AI Technical Summary
In prefabricated structures, direct connection between reinforced concrete cast-in-place or laminated plates and prefabricated reinforced concrete shear walls is difficult, especially in case of split-layer, mezzanine or cross-layer arrangements.
The prefabricated reinforced concrete shear wall reserves steel plate embedded parts at the connection position with the floor slab, and the cast-in-place steel bars or stacked plate cast-in-place steel bars are welded on the reserved steel plates, and cast-in-place concrete of cast-in-place concrete of cast-in-place floor slabs or stacked plates is poured to achieve direct connection.
Through this method, the stable and direct connection between the reinforced concrete cast-in-place plate or laminate plate and the prefabricated shear wall is achieved, solving the problems of disassembled layers, interlayers and cross-layer settings, and improving construction efficiency and structural stability.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction engineering, in particular to the design and construction of an assembled structure, which is a structural construction method for connecting a reinforced concrete cast-in-place slab or a composite slab with a prefabricated reinforced concrete shear wall. Background Art
[0002] In prefabricated structures, the connection between prefabricated reinforced concrete shear walls and reinforced concrete cast-in-place slabs or composite slabs is generally at the floor level. The top elevation of the prefabricated shear wall is set below the bottom of the floor slab. After the prefabricated shear wall is installed and fixed, the composite slab or cast-in-place slab is constructed. The connection between the upper prefabricated shear wall and the lower prefabricated shear wall needs to be at the top elevation of the floor slab. When there are staggered floors, or mezzanines, or prefabricated shear walls need to be set across floors, the floor slab (cast-in-place slab or composite slab) and the prefabricated shear wall need to be directly connected. Utility Model Content
[0003] The utility model provides a structural construction method, which solves the problem of directly connecting a reinforced concrete cast-in-place slab or a composite slab with a prefabricated reinforced concrete shear wall.
[0004] The solutions provided by the utility model include:
[0005] Precast reinforced concrete shear walls have steel plate embedded parts reserved at the connection position with the floor slab, the cast-in-place slab steel bars or the cast-in-place layer steel bars of the composite slab are welded to the reserved steel plates, and after pouring the cast-in-place floor slab or the cast-in-place layer concrete of the composite slab, direct connection between the reinforced concrete cast-in-place slab or the composite slab and the precast shear wall is achieved.

[0009] Precast reinforced concrete shear walls have embedded steel plates at the connection with the floor slabs. When the floor slabs are composite slabs, steel supports need to be welded. During construction, after the precast reinforced concrete shear walls are installed and fixed, the cast-in-place slab formwork or the composite slab bottom plate is hoisted, and the upper and lower steel bars of the cast-in-place slab or the cast-in-place layer of the composite slab are welded to the embedded steel plates. After the formwork and steel bar binding are completed, cast-in-place concrete is poured to realize the direct connection between the precast reinforced concrete shear walls and the reinforced concrete cast-in-place slabs or composite slabs.
