As is known to all, building formwork is a kind of plate product commonly used in modern home decoration, which has been widely used in recent years. Building formwork manufacturers use the panel and inner panel to make a kind of glue through wood glue. Generally, the building template has three or more layers, mainly odd layers, and the physical and mechanical properties of the wood have been significantly improved after modern micromachining. The increase of plate size makes it more suitable for the manufacture and construction of furniture. When selecting, we need to ensure that the wood grain on the front of the board is clean, smooth, smooth, not rough and free of burrs, and the high-quality board should be free of defects such as damage, scratch, scratch and second-hand goods.
The building formwork has small deformation probability, large size and convenient construction. In order to tell you what to pay attention to when putting the plate into the formwork. First of all, place the wood vertically on the workbench, the joint should be as small as possible, and the board should be flat. Secondly, level the slab with putty or seal it with dry tape to avoid mud and mud polluting the edge of the slab. Then it is forbidden to collide with hard objects or drag crowbars, litters and steel bars onto the board.
In the current house construction, we often use building templates. Formwork works have a significant impact on the construction cost. In general industrial and civil buildings, the average is 1m ³ Formwork required for concrete 7.4m ²， The cost of formwork accounts for 34% of the cost of concrete works. The selection of reasonable formwork method, formwork structure and construction method in the construction of concrete structure has a significant effect on accelerating the construction of concrete engineering and reducing the cost. Building formwork is an important turnover material in the construction of the main structure of civil engineering, and an important factor in determining the quality of concrete forming, the strength of formwork erection, construction power and cost. How to improve the construction quality, improve the power of formwork erection and reduce the construction cost is an urgent problem to be solved by the construction party of the wide formwork project. To deal with these problems, it is necessary to make clear the types and use of various templates.
The building template manufacturer introduced the reusability of the product:
First of all, a layer of paint can be painted on the formwork, which is referred to as the laminated plate for short. After that, it has good physical properties and adhesion (the bonding strength with steel is up to 9MPa), wear-resistant, alkali resistant, and can be reused for many times, which can effectively protect the construction formwork.
Secondly, the formwork paint has excellent anti-corrosion and antirust properties. Due to the isolation effect of the paint film, the construction formwork can be protected from the abrasion of concrete sand and stone and the corrosion of cement hydrate, which can effectively improve the reuse rate of the construction formwork, thus extending the service life of the construction formwork.
Thirdly, the surface of formwork paint film is bright and full, with good smoothness, and can naturally form enamel to remedy the surface defects of building formwork.
Fourth, the thermal decomposition temperature of the template paint film is about 350 ℃, and it has good heat resistance and alkalinity (the physical and chemical properties of saturated calcium hydroxide soaked at 80 ℃ for 48h do not decline), which is very suitable for the use environment of building templates.
