Nowadays, more and more construction projects are using multi-layer building panels, leading to the existence of many defective products in the market. So how should we choose and purchase multi-layer building panels? How should the quality of multi story building panels be judged?

　　Many people may not be clear about it, but today, building formwork manufacturer Hongshi Wood Industry will discuss it with everyone.

　　How to judge the quality of multi story building panels? Mainly from six aspects

　　1. The edges and corners should be neat, the surface should be bright, flat, without cracks or peeling (individual areas for repair are allowed without affecting the quality of use), all of which are considered qualified.

　　2. Due to loading and unloading, some edges and corners may have scratches, which do not affect the quality of use and are considered qualified.

　　3. Take 3 ‰ of the entire batch and saw it in the middle, without any voids or layers. If it reaches 8-9 layers, it is considered qualified.

　　4. The thickness shall be randomly checked in a random manner, with a tolerance of ± 0.3mm for each piece or ± 3cm for the entire package.

　　5. Each corner should be in a square shape and there should be no diagonal angles.

　　6. Each length and width must meet the standard, and there should be no length phenomenon. If there is a length, it is considered unqualified.

　　How to choose high-quality Guangxi multi-layer boards

　　Based on the above six aspects, it is recommended to check when selecting multi-layer boards. It is recommended to use the entire multi-layer board as the building template, and try to use a 10-18mm thick multi-layer building template with phenolic resin coating. The edge of this type of building template is damaged after multiple uses, and it needs to be cut in a timely manner to ensure that the edges of the multi-layer board are flat. The construction of buildings with beam column structures should use medium-sized composite building templates. Due to the frequent changes in the cross-section of beams and columns, it is not suitable to use multi-layer panels for cutting, so it is suitable. In the construction industry, the selection of building materials is crucial. Any slight differences can lead to the failure of engineering projects, so normal material selection is particularly important.

　　The axial displacement of building membrane panels is a common quality issue in engineering, and almost many projects have this situation to some extent, mainly because after the removal of building membrane panels, it is found that the actual position of columns and walls is offset from the building axis position. Why does this phenomenon occur? The main reasons are careless sampling or unclear technical disclosure, the assembly of building membrane panels not being in place according to regulations or errors in axis measurement during assembly, as well as the lack of infinite or limited positioning measures at the root and top of wall and column formwork. Today, the manufacturer of building laminated panels will give you a few solutions:

　　1、 We can design templates specifically based on the characteristics of concrete structures to ensure that the templates and their supports have sufficient strength, stiffness, and stability.

　　2、 Reliable limiting measures must be installed at the root and top of the wall and column building membrane panels, such as using short steel bars embedded in the cast-in-place floor concrete to fix the steel support, to ensure accurate bottom position.

　　3、 When supporting the formwork, horizontal and vertical lines should be drawn, and vertical verticality control lines should be set to ensure accurate horizontal and vertical positions of the building membrane panels.

　　4、 After the construction of building membrane panels is completed, what should be paid attention to when pouring concrete:

　　1. When pouring concrete, the material should be evenly and symmetrically discharged, and the pouring height should be strictly controlled within the allowable range of construction specifications.

　　2. The manufacturer of building membrane panels said that before pouring concrete, the template axis, brackets, top supports, and bolts should be carefully inspected and rechecked, and any problems found should be dealt with in a timely manner.

　　Many construction companies choose to use laminated panels for support during construction. Why do people choose laminated panels when there are so many building materials? Firstly, laminated board is one of the higher grade building templates and is frequently used in daily life. In order to meet the needs of different building environments, laminated board needs to pay more attention to daily maintenance during use. To ensure that the laminated board does not deform during transportation and has good glossiness. Avoid contact with products with strong acidity and alkalinity during storage.

　　In the past decade, manufacturers of laminated panels have been doing well in business, and traditional templates have gradually been replaced by laminated panels. Why do engineers like to use laminated panels? It is because the laminated board mainly has the following characteristics:

　　1. Laminated panels have the characteristics of no warping, no deformation, no cracking, good water resistance, easy demolding, high turnover times, and long service life.

　　2. Laminated panels can prevent corrosion from corrosive substances and will not contaminate the surface of concrete. The environmental friendliness is also relatively good.

　　3. The surface of the laminated board is smooth and beautiful, which can reduce the secondary plastering process of the wall. It can be directly used for veneer decoration and can also shorten the construction period.

　　4. As is well known, laminated panels have good insulation performance and can be used in winter construction.

　　5. Laminated panels can be processed into various shapes of templates according to construction needs, with strong plasticity.

　　6. Another major feature of laminated panels is their lightness, making them more suitable for high-rise building and bridge construction.

　　7. The width of the laminated board is larger than that of traditional templates, and using laminated boards can reduce the number of joints and improve the efficiency of formwork support.

　　Building formwork is one of the main materials widely used in engineering construction, mainly playing a role in concrete support and shaping. Therefore, it has high requirements for the strength of the board. In addition to controlling the processing, manufacturers also need to pay attention to some matters when using it. Below, let building formwork manufacturers explain some factors that affect strength.

　　Firstly, when using it, everyone should choose templates that match the construction standards, because building templates have different materials and specifications, so their load-bearing performance is also different, with some differences. It is necessary to choose products with appropriate strength to prevent cracking and danger caused by excessive load.

　　Secondly, the different materials used for the board, that is, the difference in raw materials, will ultimately affect the strength and quality of the finished product. In order to ensure safety and efficiency during construction, it is important to pay attention to whether the strength of the board meets the requirements when purchasing.

　　Finally, it will be affected by the surrounding environment of the template. If the surrounding environment is too dry, it is easy to cause a large amount of water inside the board to evaporate, resulting in stress imbalance inside the board and ultimately leading to cracking. At this time, the strength of the board will naturally decrease significantly.

　　The use of building templates is to facilitate the construction process. Once the concrete has dried, it must be removed, otherwise it will affect the progress of construction. Demolition also requires methods, and the specific details should be explained to us by the building template manufacturer.

　　1. The dismantling time is very important: there is no specific dismantling time, and it mainly depends on the degree of dryness of the concrete. The standard for identifying the degree of setting is actually very simple. As long as you keep an eye on it, the edges and corners of the concrete block will not be damaged, and you can also ensure that it will not be damaged (dismantling too early can cause concrete damage, affecting the quality of the building).

　　2. In order: The most basic order is to demolish from top to bottom. First, demolish the smaller ones, then demolish the larger ones. First, demolish the non load-bearing ones, and then carry out the load-bearing ones. First, demolish the two sides and then the middle ones. This is the most basic way of demolishing. Demolition requires skills and should not be done forcefully.

　　The above are some key points about the demolition of building formwork. We hope everyone can operate according to the requirements.

　　As a commonly used building material, quality assurance is crucial in the production and manufacturing of building formwork. The smoothness and flatness of the formwork surface will directly affect the flatness of the engineering concrete surface. To ensure good product quality, the main manufacturing process is as follows:

　　1. Pay attention to the cutting of raw materials. According to the size of the template, cut the wood layer into layers with the same proportion, and remove the magazine on the surface of the wood layer. The magazine can affect the bonding strength of the adhesive in the later stage, and cut horizontally according to the required thickness.

　　2. Do a good job of drying and drying treatment. When producing building templates on a large scale, wood dryers are used for drying treatment. The dried wood layer is relatively brittle, so it should be naturally left for 2-3 days to ensure the toughness of the wood layer.

　　3. Gluing treatment. There is a dedicated glue rolling machine set up, which passes the wooden board through the glue filling machine. The front and back sides of the board will be evenly coated with glue. The wooden board with the glue layer will be placed flat on the surface of the template, and the glue should be evenly spread to meet the requirements.

　　4. Carry out surface painting and treatment. During the production and manufacturing process of building templates, there may be a small amount of misalignment and irregular edges of the inner layer wooden boards. The excess boards are cut with a knife and coated with anti-corrosion paint, which is beneficial for extending their service life.

　　The above introduces the important details of building templates in the process of cutting, drying, gluing, painting, and finishing manufacturing. Through these measures, the produced building templates have the characteristics and advantages of light weight, strong resistance to gravity, and strong anti-corrosion effect, which are highly welcomed by customers! Hongshi Wood Industry provides various types of building templates, with a maximum turnover of 15 times or more.

　　Building templates are used in construction, so what are the precautions that must be taken when constructing building templates on rainy days? Hongshi Wood Industry takes you to understand:

　　Pay attention to weather forecast: During construction, it is important to understand the recent weather forecast, especially the rainfall situation. This helps to avoid important template installation and disassembly work during rainfall, as rainwater may damage the surface of the template or cause it to become wet and heavy, making it difficult to operate.

　　Template isolation layer protection: Before applying the isolation layer, it is necessary to understand the weather forecast to prevent the isolation layer from being washed away by rainwater. If rain is expected, it is recommended to apply an isolation layer in dry weather and ensure that the isolation layer is completely dry before installing the template.

　　On site drainage: Ensure that the construction site has a good drainage system to prevent rainwater accumulation. If possible, formwork construction should be avoided in areas with rain or high groundwater levels.

　　Stable template support: The template support must be stable to prevent tilting or collapse in the rain. If the support system is not stable enough, danger may occur in the rain.

　　Anti slip measures: During the installation and disassembly of the template, attention should be paid to anti slip measures. It is recommended to use anti slip shoes and gloves to prevent operators from slipping or templates from falling and causing injury.

　　Tool and equipment protection: When working in the rain, ensure that tools and equipment (such as drills and hammers) are kept dry. Wet tools may cause difficulties in operation and even pose a danger to operators.

　　Safety awareness: Maintain a high level of safety awareness under any weather conditions. During rainy construction, safety awareness is particularly important as the environment may become slippery or visibility may be affected.

　　Nowadays, the construction machinery and technology of building wooden formwork are relatively proficient, and the loss rate can be basically fixed. Therefore, the key element of building wooden formwork construction is the human factor. Below, building formwork manufacturers will introduce how to control the loss rate of building wooden formwork.

　　Elements of construction plan

　　The construction template manufacturer introduced that when planning the construction plan for building wooden templates, a reasonable construction plan should be selected based on different template types and engineering characteristics. A reasonable construction plan has a huge impact on the engineering cost of the entire formwork project. So when selecting the template construction plan, engineering personnel need to undergo strict accounting and review, including the entire template structure system and usage, to reduce the use of wooden templates and then reduce the total loss of templates. The equipment and removal of templates should be as specific as possible, and the construction process should be standardized, such as applying release agents, precautions for template removal, etc., in order to maintain the template as much as possible and improve its utilization rate.

　　The elements of a carpenter team

　　The same project, the same plan, and the selection of different construction teams will result in significant differences in the usage and loss of templates. So it is necessary to improve the technical level and sense of responsibility of the carpenter team members. For example, some construction teams can turnover a set of templates 10 times or even more, while others can only turnover a set of templates 3-5 times, resulting in a significant difference in the amount of work. Due to the improvement of the technical level and sense of responsibility of the carpenter team members, the loss rate of templates can be effectively reduced. Nowadays, there is a high turnover of construction workers, and the carpenter team is composed of temporary workers with varying levels of professional skills, which has a significant impact on the loss rate of formwork. Therefore, the essence of advancing carpenter team workers is a major way to increase the utilization rate of templates. The company should arrange regular training for construction workers, conduct certification exams, obtain work permits, and implement the integration of certification and personnel. Only in this way can we effectively advance the power of workers and reduce the loss rate of wooden templates.

　　Elements of Engineering Processing Personnel

　　The construction template manufacturer introduced that compared to a general project department, a project department that is skilled in processing will have a significant difference in project costs. Therefore, the technical level of project processing personnel can effectively reduce project costs by improving their sense of responsibility. The same goes for template engineering. For example, project personnel strictly regulate the processing and production of templates, supervise carpenter team members to process and produce according to construction requirements, check the methods of wooden template equipment and removal during the construction process, command carpenter template engineering personnel to work, advance work power, and reduce the loss rate of templates.

　　The construction template manufacturer reminds everyone to check whether the wooden products have been removed according to the construction requirements when removing the formwork, rather than randomly removing them. Prohibit smashing or prying. The removed building wood formwork shall be cleaned in time, stacked neatly, and covered when it rains, otherwise it is easy to produce foam and other defects, and then reduce the loss rate of building wood formwork.

　　Building formwork is an essential and important material in construction engineering, accounting for a considerable proportion of the entire project cost. Choosing the right building template can save money and shorten the construction cycle! However, among the many types of building templates, wooden templates are the most commonly used. Today, Hongshi Wood Industry Template will introduce you to mainstream wooden building templates and their characteristics, as well as how to choose them.

　　1、 Red face template

　　Red faced template is an early type of building template, with a surface made of red melamine waterproof adhesive and a core made of different wood materials such as poplar, pine, and eucalyptus. Due to its low weight, it is convenient to use.

　　2、 Phenolic mirror template

　　The building phenolic mirror template is an upgraded product of the building red template. The materials used are strict, and the drier the core material, the better. The production cycle is long, and all are formed by secondary hot pressing. Its surface adopts a more advanced phenolic adhesive, which is smoother and easier to demold. Due to its smooth surface resembling a mirror, it is named Mirror Surface Template. Phenolic resin mirrored building formwork has better waterproofing properties than ordinary building formwork, and the price of building formwork is also higher than that of triamine adhesive.

　　3、 Laminated board

　　The laminating template is the best quality among the three products. It is made by covering a good artificial board with a layer of laminating paper, and then heating and pressing the laminating paper and the artificial board. Its surface adopts laminating technology, and both sides are covered with black or red laminating paper made of special adhesive. The surface of the laminated board is smooth, bright, waterproof, and fire-resistant, with excellent durability (weather resistance, corrosion resistance, chemical resistance) and strong anti fouling ability. The use of membrane board construction makes the surface of the cement mold smoother, can be demolded better, avoid secondary ash, greatly improve work efficiency, and save manpower and material resources. At the same time, it will not cause any pollution to the building and can strictly control the amount of harmful gases.

　　How to choose the appropriate template?

　　The construction of basements, factories, and ground floors usually requires the use of building red boards. Mid story buildings can be upgraded with red panels and mirror panels. It is recommended to use laminated panels for the construction of high-rise buildings and important bridges.

　　Hongshi Wood Industry provides red panels, mirror panels, laminated panels, and clear water panels. High quality templates adopt full core technology, which has high strength, is not easy to crack, and is used frequently. The size of the templates is complete, and customized template solutions can be provided according to customer needs.

　　In terms of production specifications, traditional building templates can generally only produce two sizes. 915 * 1830, 1220 * 2440, and ultra strong composite templates can be produced in any size according to the engineering design structure size, customization, and standardization. This can save materials, production time, construction time, and labor costs. That is to say, workers can earn more money, and contractors can earn more money.

　　It consists of a panel and a support system. The panel is the part that forms the shape of concrete, and the support system is the structural part that stabilizes the position of the panel and bears the upper load. The quality of formwork is related to the quality of concrete engineering. The key lies in accurate dimensions, firm assembly, tight joints, and convenient disassembly and assembly. To achieve good technical and economic results, appropriate templates should be selected based on the structural form and characteristics.

　　It is necessary to calculate the templates and support systems for large and special projects, and check the stiffness, strength, stability, and lateral bearing capacity of the templates and support systems.

　　Material requirements:

　　1. The basic template is made of pine wood, poplar wood, and eucalyptus wood, and the thickness of the side plate of the floor beam is 20mm.

　　2. The bottom formwork of the main beam is made of pine wood board. The thickness of the bottom mold is 40mm. The thickness of the column and ground molds is 12 mm.

　　3. The support system adopts cedar logs with a diameter of no less than 70mm, small square logs with a size of 400 × 500mm are used for pulling, and steel pipes are used for the bottom support system.

　　4. Wooden formwork and support systems shall not use fragile, severely deformed, or damp wood.
