What is the building template

The building template is actually a kind of support structure, which is composed of three parts: panel, support structure and connector. The supporting structure of the panel is a temporary structure supporting the panel, concrete and construction load. The connector is an accessory that connects the panel and the supporting structure into a whole. In this way, the structure of the building formwork is firm, and it is not easy to be deformed and damaged. According to the nature of materials, building formwork （Linyi Luju International Trade Co., Ltd. has the brand leader and cc film faced plywood） can be divided into building formwork, building wooden plywood, laminated plate, multi-layer plate, double-sided adhesive, double-sided laminated building formwork, etc. According to the construction process conditions, it can be divided into cast-in-situ concrete formwork, pre-assembled formwork, large formwork, and leaping formwork, etc. According to the type, it can be divided into combined steel formwork, cast-in-situ concrete structure, aluminum formwork, etc. The purpose of construction formwork is to ensure the quality of the project, which will speed up the construction progress and reduce the labor cost.
The types of building formwork mainly include wood building formwork, steel and wood building formwork, steel and bamboo building formwork, plastic building formwork, etc. Let's compare the characteristics of various types of building formwork:

1、 The wood plywood formwork has high strength and good toughness. The static bending strength of the board is 8-10 times of the wood strength and 4-5 times of the wood plywood strength. The use of wood formwork can reduce the number of supports. The width of wood plywood formwork is wide, and there are few seams. There are two common specifications in the market: 1830 * 915mm and 2440 * 1220mm, which are equivalent to the area of 6.6 P3015 small steel formworks, and the speed of formwork erection and removal is fast.
1. The surface of the wood plywood formwork is flat and smooth. The adsorption force of the wood plywood formwork surface coated by the construction formwork manufacturer to the concrete is only one eighth of that of the steel formwork, so it is easy to demould. The concrete surface is flat and smooth, which can reduce the plastering operation and shorten the duration of the decoration operation.
2. The wood plywood formwork has good water resistance and does not open the glue after boiling for 6 hours. It can still maintain high strength after boiling and freezing. The surface water absorption of wood glue formwork is close to that of steel formwork, and the water retention of concrete surface can be significantly improved by pouring and tamping concrete with wood plywood formwork. In the process of concrete curing, it will not deform in case of water, which is convenient for maintenance.
3. The wood plywood formwork shall be protected from corrosion and moths.
4. The thermal conductivity of wood plywood formwork is 0.14-0.16w/m.k, which is far less than the thermal conductivity of steel formwork, which is conducive to thermal insulation in winter construction.
5. The wooden plywood formwork has high turnover times and obvious economic benefits. The board can be used on both sides without frame
2、 Steel and wood building formwork: steel and wood building formwork is a stereotyped building formwork with angle steel as the frame and wood building formwork as the panel. Its advantage is that it can make full use of short wood and can be used repeatedly.
3、 Steel and bamboo building formwork: steel and bamboo building formwork is a stereotyped building formwork with angle steel as the frame and bamboo woven plywood as the panel. This kind of building formwork has large rigidity, is not easy to deform, is light in weight, and is easy to operate.
4、 Steel building formwork: steel building formwork is generally made into stereotyped building formwork, which is assembled into various shapes and sizes with connecting members, suitable for various structural forms, and widely used in the construction of cast-in-place reinforced concrete structures. The steel construction formwork has a large investment at one time, but a high turnover rate. In the process of use, attention should be paid to storage and maintenance, to prevent rust, and to extend the service life of the steel construction formwork.
5、 Others, such as plastic building formwork, glass fiber reinforced plastic building formwork and aluminum alloy building formwork, have the characteristics of light weight, high rigidity, convenient assembly and high turnover rate, but they have not been widely used in construction due to high cost.
What are the uses of building templates?
Construction formwork is used frequently in the construction industry. It can be said that it is an indispensable building material in engineering construction. To put it bluntly, the building template is actually the red or black that is often seen on the construction site

The main role of wood board is to support formwork and bear load in construction projects, bridge construction, tunnel water conservancy and other projects.
The combined steel formwork can play the role of reinforcement when used as building materials. This frame structure can protect the supporting frame and make the building more solid during construction;

The construction formwork of cast-in-place concrete structure is used as a temporary structure and can be removed, so that the newly poured concrete can be formed and maintained faster;

Building wood plywood can play the role of thermal insulation and maintenance in engineering, because the thermal conductivity of wood plywood is low, not only in engineering, but also in the artificial wood used in many of our home decoration;

The building formwork of reinforced concrete structure is to ensure the support of the shape, size and space position of the building formwork.
