Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an assembled template suitable for the construction of plain concrete beams and slabs. Background Art

[0002] Fair-faced concrete beams and slabs refer to the combination of beams and slabs cast in place during the floor construction process. In the subsequent construction, only a layer of waterproof membrane is sprayed on the surface, and no external decoration such as painting or tiling is required. Therefore, the casting formwork of the fair-faced concrete beams and slabs is the key to the quality of the entire beam and slab forming.

[0003] Most of the existing casting formworks for plain concrete beams and slabs are wooden board structures. The beam structure in the beam and slab protrudes from the lower end of the slab structure. When the wooden formwork is used to build the casting formwork of the beam structure, the first bottom formwork and the side formworks on both sides of the beam structure are independently fixed using horizontal or vertical struts. Since the thickness of the beam structure in different environments is different, the struts used to support the formwork for beam structures of different thicknesses are not universal, and it is necessary to propose improvements.
