Description
Technical Field
The utility model relates to structural design and factory manufacturing of an industrial steel structure building (fabricated steel structure building), and site construction, namely fabricated construction, in particular to a double-steel-plate concrete combined shear wall for assembling and stiffening bolt and lock pieces.
Background
In steel structures, particularly residential steel structure buildings, the steel plate composite shear wall is easier to accept by vast residents than steel frame and frame support structure buildings due to the fact that exposed columns and exposed beams are few indoors, and the steel plate composite shear wall is widely used in high-rise residences. Fig. 1 shows 5 kinds of construction schematic diagrams of the steel plate composite shear wall.
At present, a steel pipe bundle column shear wall structure is also provided by Hangzhou Xiao steel structures, and is also a steel plate combined shear wall form with concrete poured in steel plates, as shown in figure 2.
In the existing steel plate composite shear wall, the stud connection is adopted (a) most, and a special stud welding machine can be adopted for welding the stud and the steel plate in a factory, so that the specialization degree is high, the welding quality is stable and reliable, and the production efficiency of workers is highest; (b) the form and the mechanical property of the T-shaped stiffening rib are similar to those of the stud, only the T-shaped stiffening rib is welded without professional equipment, the welding efficiency is low, the steel plates can be horizontally arranged and welded when the connecting piece is welded on the combined shear wall of the two steel plates, the processing is convenient, and the two steel plates and the end plate are assembled and welded to be processed and finished. The outsourcing steel plates of the two steel plate combined shear walls are not connected except the middle of the wall end and the outer wall body. Both of these two types of steel plate composite shear walls present a problem: when concrete is poured and tamped into the steel plate wall in construction, the steel plate can bulge outwards and deform due to pressure generated on the side wall of the steel plate; if the concrete is poured and tamped for 3 to 4 layers at a time, the lateral pressure generated by the 12 meters of liquid concrete and the additional pressure of vibration generated when the vibrating spear vibrates to tamp the dense concrete are high, and the plate explosion often occurs due to the large pressure value. Because the function of the studs or T-shaped stiffening ribs is to integrate the steel plate and the concrete filled in and prevent the two from separating from each other. Under the action of compressive stress, the steel plate has the tendency of local buckling outwards, and the design only considers the tensile force borne by the part of the stud and the T-shaped stiffening rib in the compression stage. The designed width-thickness ratio of the plate is the ratio of the width to the thickness of the steel plate between the stud and the T-shaped stiffening rib, the outward local buckling of the steel plate can be limited only in the use stage under the compression state of the plate, the calculated width of the outward buckling of the plate in the construction stage is the distance between the transverse steel plates at the end part of the straight section of the wall body, and no connection between the two outer-wrapped steel plates needs to take measures to control the steel plate explosion.
(c) The batten plate connection or (d) the split bolt connection is used as the combined shear wall of the other two steel plates connected between the steel plates, the lateral pressure of the cast concrete can be balanced by the connection between the steel plates before the concrete is hardened, and the plate explosion is not easy to generate. However, the batten plates are welded in a closed space, and are not used much due to difficulty in processing and manufacturing, and can be welded between steel plates unless the batten plates are used for a shear wall with the thickness of more than 600mm, the number of holes formed in the split bolt steel plates is large, bolt heads on the outer sides of the steel plates are exposed, the shear wall surface needs post-processing, and a large amount of labor is needed.
The steel tube bundle column shear wall structure is pushed out by Hangzhou Xiao steel structures, the problem of steel plate explosion is well solved, special welding equipment is developed to realize automatic welding of a machine, and the working efficiency is high. However, the welding amount of each wall is very large, two vertical through long welding lines are formed at intervals of a certain width determined by a production mode, the number of factors causing defects of the welding lines is large, the carbon emission amount corresponding to the large welding amount is large, each closed cavity needs to be independently poured and compacted when concrete is poured and tamped, and construction is complex.
