A prefabricated steel formwork for prefabricated stairs

Abstract

The invention relates to the technical field of building construction, in particular to a prefabricated steel formwork for stairs of an assembled building. It includes a support frame set on the ground, the support frame is provided with a first support plate, and one end of the first support plate close to the ground is rotated to be provided with a second support plate that fits the ground, and the first support plate Stair side panels are vertically arranged on both sides of the slab, and a stair panel module that is rotatably connected to the second support panel is provided between the stair side panels. Hold-down device for holding down the stair module. The steel formwork for prefabricated stairs of an assembled building provided by the invention has the effect of convenient disassembly and installation.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated steel formwork for stairs of an assembled building. Background technique [0002] In house construction, stairs have functions such as up and down passage and beautiful decoration. Usually, the construction of stairs is completed by pouring concrete. Concreting refers to the process of pouring concrete into a mold until it solidifies. After curing, the mold can be removed to obtain the stairs. [0003] The mold used in traditional stair pouring is mainly composed of base plates, side plates, kick plates and pedals made of wooden materials. First, the base plate is installed and supported and fixed by supporting frames, and then the side plates are fixed to the base plate one by one with screws. After that, the kick board and the pedal are fixed vertically and alternately to the side board by screws, and then concrete is poured into the mold cavity f...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: during the installation of the stair formwork, it is necessary to use tools such as hammers to knock the side panels, kick plates and pedals one by one to remove them, which is cumbersome and expensive to install; when removing the formwork, it is also necessary to Use tools such as hammers to knock the side boards, kick boards, and pedals one by one, which takes time to disassemble; moreover, because the stair formwork is connected by nails, it is easy for the nails to sink into the cured stairs, further increasing the formwork Difficulty of dismantling
