Embodiment 1

[0045] Refer to attached Figure 1-Figure 5 , Figure 13 and Figure 14 As shown, a prefabricated steel structure laminated shear wall, its wall panel 3 is a new type of prefabricated lightweight concrete wall panel, in the factory, polystyrene, cement, additives and water are used as raw materials, and through specialized machinery A new type of prefabrication in which the equipment is manufactured into a cement polystyrene formwork plate with horizontal and vertical holes (using it as a formwork), and self-compacting vibration-free concrete is used to form horizontal and vertical criss-cross grid members in the formwork holes. Concrete siding. The number of wall panels 3 is two, and the two wall panels 3 are anchored together by the angle steel self-locking component 1 and the self-locking component 2 2 on both sides, and there is a hollow layer between the two wall panels 3. After hoisting Concrete can be poured; each wall panel 3 is provided with multiple longitudinal g...

Embodiment 2

[0048] refer to Figure 6 and Figure 7 As shown, it is the on-site splicing process of the prefabricated steel laminated shear wall: after the previous shear wall is fixed and formed, the self-locking member 2 of the second shear wall is docked with the self-locking member 1 of the previous shear wall , docked and inserted from above, the entire wall can be automatically locked by self-locking component 1 and self-locking component 2 2, and the remaining walls are connected in sequence, and finally concrete is poured, and the high-fluidity concrete can automatically compact each wall. Thus pouring into a whole. Self-locking component 1 and self-locking component 2 2 are self-locking tools, which can clamp two wall panels 3 of a single wall to form a wall, and are also the connecting parts when the two walls are docked, and finally cast High fluidity concrete. The shear wall panel is a single-piece shell formed by pouring and molding according to certain specifications and si...

Embodiment 3

[0056] refer to Figure 8-Figure 12 As shown, the prefabricated steel structure laminated shear wall also includes the inner wall, outer wall and internal steel skeleton of the main beam - I-beam 5, which is welded by multiple T-shaped steel materials at the bottom of the web to form a ┻-shaped or ╋-shaped, as a connecting member, it can replace the structural ribs at the beams, structural columns and edge joints—that is, it is poured into a structural steel skeleton, and its flange width is based on the size of the self-locking member-1 joint, and the height and thickness of the web are based on the actual beam and slab size 1. Design of structural column stress requirements, if necessary, formwork is required to cast beam-column joints.

[0057] On-site splicing process of prefabricated steel structure laminated shear wall interior wall and exterior wall: install three pieces of shear wall on site and fix them with temporary fixing brackets. This bracket is similar to constr...

Abstract

The invention provides a prefabricated steel structural superposed shear wall and a construction method thereof. According to a prefabricated steel structural superposed shear wall plate, each shear wall comprises two double-faced heat preservation light wall plates; a deep longitudinal groove and a plurality of rows of transverse holes penetrating through the groove are formed in each wall plate;and self-locking components formed by welding a plurality of steel plates are arranged on the left and the right of a wall body, and the wall body can select different chaining lock catches and tailend lock catches according to different joints. The upper, lower, left and right portions of the wall body are all of symmetrical structures, a plurality of rows of transverse penetrating reinforcingsteel bars are arranged in the wall body, longitudinal reinforcing steel bars are connected with the transverse reinforcing steel bars in a lap joint or welded mode, and short bars are welded to the joint points of the transverse reinforcing steel bars and the longitudinal reinforcing steel bars. The construction method of the prefabricated steel structural superposed shear wall comprises the following steps that in-situ wire paying off is conducted, and temporary fixing frames are mounted; the shear wall is assembled and spliced in place, and connected and fixed to the temporary fixing frames; a prefabricated upper layer floor slab is placed in place; hidden beam steel plates and various additional reinforcing steel bars are arranged, and pipelines are arranged; high-fluidity free of vibration concrete is poured; and mounting construction of a next layer is entered in.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a prefabricated steel structure laminated shear wall and a construction method thereof. technical background [0002] Shear walls are also called wind-resistant walls, seismic walls or structural walls. Walls in houses or structures that mainly bear horizontal loads and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. [0003] The existing prefabricated shear wall structures mostly use sleeve grouting connections, steel bar welding connections or lap grout anchor connections, all of which have problems such as high cost, high construction precision requirements, and difficult construction, which make the implementation of prefabricated shear walls difficult. Big. Contents of the invention [0004] In order to solve the above problems, the object of the present invention is to provide a prefabricated steel structure laminated shear wall ...
