Stair connecting piece, manufacturing method, aluminum formwork system utilizing stair connecting pieces and stair construction method

Abstract

The invention provides a stair connecting piece, a manufacturing method, an aluminum formwork system utilizing the stair connecting pieces and a stair construction method. The stair connecting piece comprises a stepped main body, wherein side plates perpendicular to a step surface are arranged on two sides of each step of the main body, pin holes A are formed in the side plates, connecting plates perpendicular to the side plates are fixedly arranged on the corresponding side plates, and pin holes are formed in the connecting plates. The aluminum formwork system comprises stair aluminum formworks and wall aluminum formworks, each stair aluminum formwork is connected with the corresponding wall aluminum formwork through the corresponding stair connecting piece. During stair construction, the wall aluminum formworks are arranged firstly, then the stair connecting pieces are arranged and connected with the wall aluminum formworks, then the stair aluminum formworks are built and connected with the stair connecting pieces, concrete is poured, and the equipment is disassembled after the concrete is set. The stair connecting piece which is simple in structure, low in cost and simple and convenient to operate, facilitates splicing of the stair aluminum formworks and the wall aluminum formworks and provides great convenience for construction, the manufacturing method of the stair connecting piece, the aluminum formwork system utilizing the connecting pieces and the stair construction method utilizing the system are provided.

Description

technical field [0001] The invention relates to the field of aluminum formwork construction, in particular to a staircase connector for building stairs, a manufacturing method, an aluminum formwork system using the same, and a staircase construction method. Background technique [0002] Such as figure 1 , figure 2 As shown, the existing aluminum formwork for stairs includes a base plate 1', a vertical plate 2' and supporting guard plates 5' on both sides, the upper end of the vertical plate 2' is provided with an upper connecting plate 3', and the lower end of the vertical plate 2' is connected to the One end of the base plate 1' is vertically connected, the other end of the base plate 1' is provided with a lower connecting plate 4', the two ends of the lower connecting plate 4' are connected with the supporting guard plate 5', and the bottom of the lower connecting plate 4' is connected with the base plate 1' , The lower connecting plate 4' is a vertical structure.

AI Technical Summary

Problems solved by technology

Before the pouring is completed and the aluminum formwork is not removed, the construction workers still need to transport construction equipment by going up and down the stairs. Since the upper and lower steps in the existing aluminum formwork structure are connected by angle irons 8', the lower connecting plate 4 on the bottom plate 1' 'It is also a vertical structure, so the aluminum formwork after pouring concrete is not conducive to the construction personnel going up and down, especially when carrying a lot of items, it is also prone to safety accidents, and the construction safety cannot be guaranteed

At the same time, the edge of the existing aluminum formwork for stairs is also stepped, which cannot be spliced ​​with the aluminum formwork for the wall, which brings great inconvenience to the construction
