Extended data:

Building formwork is a temporary supporting structure made according to the design requirements, which enables concrete structures and components to be shaped according to the specified position and geometric dimensions, maintain their correct positions, and bear the self-weight of building formwork and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete engineering, speed up the construction progress and reduce the engineering cost.

The building formwork structure used in the construction of cast-in-place concrete structure is mainly composed of three parts: panel, supporting structure and connector. The panel is a load-bearing plate that directly contacts the newly poured concrete; The supporting structure is a temporary structure to support the panel, concrete and construction load, which ensures that the building formwork structure is firmly combined and does not deform or destroy; Connectors are fittings that connect panels and supporting structures into a whole.

Building formwork is the formwork and support formed by concrete pouring. According to the material properties, it can be divided into building formwork, building veneer, laminated board, multilayer board, double-sided laminated board and double-sided laminated building formwork. Building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork and jumping formwork according to construction technology conditions.

Composite steel formwork is a new type of formwork with strong universality, convenient disassembly and assembly and many turnover times in modern formwork technology. When it is used in the construction of cast-in-place reinforced concrete structures, it can be assembled into large formwork of beams, columns, walls and floors in advance according to the design requirements, hoisted in place as a whole, or dismantled in bulk.

Template support

1, the beam side formwork is made of wood square with an inner space of about 330mm, wood square with an outer space of 500mm, reinforced with recyclable M 12 ordinary wall bolts with a horizontal space of 500mm and a vertical space in the middle. The beam formwork adopts 18mm plywood as the panel, and the beam bottom is horizontally arranged with 60×80mm square timber with a spacing of 300mm.

Longitudinal support adopts φ48×3.5 steel pipe. Fastener-type steel pipe scaffold is used as support system. The span of scaffold beam is 1.2m, the distance between vertical poles on both sides of the beam is 0.7m, the rest of the longitudinal distance is 1.5m, and the step distance is1.5m. ..

2. The floor formwork is supported by 60mm×80mm (wood square) with the center spacing of 300mm. Fastener-type steel pipe scaffold is adopted for the support system, with scaffold row spacing 1.0m, span 1.0m and step spacing1.5m. Double fasteners are required for the connection between the cross bar and the upright post supporting the wood square.

3, wall template, vertical back stare blankly with 60 x 80 (spacing of 300 mm (starting spacing of 200mm, more than 400mm spacing, the rest of the spacing of 600mm), horizontal stare blankly with 80 x100 (spacing of 500 mm). Through punching holes in the back stare blankly, the horizontal spacing of Rachel wall bolts is 600mm, the vertical spacing is 500mm, and the diagonal braces are reinforced with three middle and lower steel pipes with a spacing of 600 mm to ensure their stability.

4. Column formwork is assembled in woodworking workshop, using 18mm bamboo plywood formwork. The vertical inner edge is about 60×80 (square @250), the column hoop is 48×3.5, and the spacing between column section B and column section H is 200 ~ 350. Reinforced with recyclable M 12 ordinary wall bolts, and steel pipes are thrown around.

At the corner of the column, sponge strips are filled with wooden boards to ensure that the edges are straight and beautiful. Bracing begins at 150mm, and every 1500mm, steel pipes are used for symmetrical diagonal reinforcement (try to take 45), and pull-through lines are used for inspection and acceptance between columns.
