Building template

The building template is a temporary supporting structure, which is made according to the design requirements, so that the concrete structure and components are shaped according to the specified position and geometric size, maintain their correct position
The formwork structure for the construction of cast-in-situ concrete structures is mainly composed of three parts: a panel, a supporting structure and a connector. The face plate is a bearing plate that directly contacts the freshly poured concrete; the supporting structure is a temporary structure that supports the face plate, concrete, and construction loads, ensuring that the building formwork structure is firmly combined so that it does not deform or break; the connecting piece is the face plate and support The structure is connected as a whole.
Architectural formwork is a formwork and bracket formed by concrete pouring. According to the nature of the material, it can be divided into architectural formwork, construction wood plywood, laminated board, multi-layer board, double-sided adhesive, double-sided coated building template and so on. Building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork, jump formwork, etc. according to the construction process conditions.
The combined steel formwork is a new formwork of "steel instead of wood" in modern formwork technology, which has the advantages of strong versatility, convenient assembly and disassembly, and a large number of turnovers. It can be used for construction of cast-in-situ reinforced concrete structures. According to the design requirements, the large-scale formwork assembled into beams, columns, walls and floors is hoisted in place as a whole, and the bulk disassembly method can also be used.
Aluminum formwork, new building formwork made of aluminum alloy, and green construction formwork emerging in the construction industry. They are easy to operate, fast in construction, high in return, environmentally friendly and energy-saving, many times used, good concrete pouring effect, and recyclable. Company adopted. On November 27, 2014, at the "Expanding Aluminum Application in the Construction Industry High-level Forum", it was proposed to expand the application of aluminum formwork, focus on promoting aluminum formwork, and implement aluminum formwork construction standards as soon as possible.
(1) Low cost: Compared with ordinary floor slabs, the use of one-time magnesia building mold shells can reduce the amount of concrete by 10-20%, the amount of reinforcing steel by 30-40%, and the overall cost by 20-30%.
(2) Flexible design: The length, width, and height of the rib beam can be arbitrarily changed. The designer can accurately calculate the height of the beam rib according to the large and small load of the floor, and does not need to design according to the fixed size of the turnover formwork.
(3) Sound insulation and heat insulation: The disposable magnesite building mold shell has good heat insulation and sound insulation effects and good fire resistance.
(4) Fast construction and short construction period: The construction process of the disposable magnesite building mold shell is simple. After the floor mold is laid, the mold shell is directly placed, adjusted, fixed, and finally the small rib beam can be bound. After the concrete is poured, the formwork is combined with the concrete without the need to disassemble the formwork, shortening the construction period, saving materials and labor costs.
Wooden building template is a kind of artificial board. Slabs made of glued veneers are criss-crossed according to the direction of wood grain and pressed under heating or non-heating conditions. The number of layers is generally odd, and a few have even numbers. The difference in physical and mechanical properties in the vertical and horizontal directions is small. Commonly used are plywood, plywood, etc.
