Embodiment 1

[0035] Such as Figure 1-6As shown, a connection device between prefabricated stairs and cast-in-situ concrete shear wall limbs in this embodiment includes a shear wall body 1, a staircase body 2, an installation base 3 and angle steel 11, and the installation base 3 includes a plurality of The stair body (2) is distributed at intervals in the length direction, and one side of the stair body (2) is rotatably connected with a rotating plate 4 . The surface of the installation base 3 and the shear wall 1 is provided with a fixing mechanism 5 used in conjunction with each other, the surface of the installation base 3 and the rotating plate 4 is provided with a positioning mechanism 6 used in cooperation, and the other side of the rotating plate 4 is installed with a support Slant bar 7, support platform 8 is installed on the other end of support slant bar 7, and the top of support platform 8 is bolted with positioning column 9, and the bottom of stair body 2 is provided with bott...

Embodiment 2

[0037] Such as figure 2 and image 3 As shown, a connection device between prefabricated stairs and cast-in-place concrete shear wall limbs in this embodiment, its main structure is basically the same as in Embodiment 1, the main difference is that the fixing mechanism 5 includes fixing bolts 51, fixing holes 52 and the fixing groove 53, the fixing hole 52 runs through the surface of the installation base 3, the fixing groove 53 is set on the surface of the shear wall 1, and the fixing bolt 51 passes through the fixing hole 52 and is threadedly connected with the inner wall of the fixing groove 53, through The setting of fixing bolt 51, fixing hole 52 and fixing groove 53, fixing bolt 51 passes through fixing hole 52 and enters the inside of fixing groove 53, just can fix installation base 3 on the surface of shear wall body 1, realize to install The base 3 has the effect of being fixed, and can also be disassembled simultaneously.

Abstract

The invention discloses a connection device between a prefabricated staircase and a cast-in-situ concrete shear wall, which belongs to the technical field of construction. It includes a shear wall, a stair body, an installation base and angle steel, one side of the installation base is rotatably connected with a rotating plate, and the surface of the installation base and the shear wall is provided with a fixing mechanism that cooperates with each other. The surfaces of the installation base and the rotating plate are provided with positioning mechanisms that cooperate with each other. The device of the present invention can fix the prefabricated staircase and the cast-in-place concrete shear wall, and effectively support the bottom of the prefabricated staircase, so that the overall earthquake resistance of the prefabricated staircase is improved, and the safety of the prefabricated staircase is improved at the same time, which solves the problem of the current prefabricated staircase. The installation of stairs is generally connected by hinge supports at the upper and lower ends of the stairs, resulting in the problem that the middle part of the bottom of the prefabricated stairs cannot be effectively fixed and supported, and the overall seismic performance of the stairs cannot be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction, and more specifically relates to a connection device between a prefabricated staircase and a cast-in-situ concrete shear wall. Background technique [0002] Compared with traditional buildings, prefabricated buildings have the advantages of energy saving and emission reduction, green environmental protection, industrialized production, rapid construction, and shortened construction period, which can improve the core competitiveness of enterprises in the industrial chain, standardize and standardize the whole industry; As a new building construction method, PC prefabricated buildings mainly produce PC components in factories and hoist them on site. The advantages are that the main assembly is fast and efficient. The prefabricated building is different from the previous cast-in-place concrete building. Since the structure of each component is directly prefabricated in the prefabrication yard o...
