Description

Technical Field

[0001] The utility model relates to the field of wall joint connection devices, in particular to a steel structure component used for joint connection of double-leaf cavity superimposed walls. Background Art

[0002] The double-leaf cavity composite wall is a special building structure system, which mainly consists of prefabricated double-leaf shear walls as formwork and load-bearing components, and cast-in-place construction is carried out in the double-leaf cavity. In construction, this technology replaces the traditional fully prefabricated assembled structure, thereby improving construction efficiency and structural strength. In addition, the double-leaf composite shear wall also uses a "U-shaped" reinforcement anchor connection to replace the traditional grouting sleeve connection, further enhancing the stability and safety of the wall.

[0003] The utility model with announcement number CN219732355U discloses a steel structure assembly for joint connection of double-leaf cavity composite wall, which solves the technical problems of weak seismic performance, low construction efficiency, and long construction period at the joint of the upper and lower layers of the existing double-leaf cavity composite wall. The technical solution of the utility model includes a vertical steel column for running through the double-leaf cavity composite wall from top to bottom, the vertical steel column is vertically connected with a joint steel beam, and the joint steel beam extends laterally to the outside of the double-leaf cavity composite wall. The upper and lower ends of the vertical steel column are provided with mutually matching plug-in structures, and the upper and lower adjacent vertical steel columns are plugged and fixed by the plug-in structure. The utility model can directly connect the vertical steel bars of the upper and lower wall bodies, improve the seismic performance of the joint of the upper and lower double-leaf cavity composite wall, and at the same time, the vertical steel column is used as the shear wall constraint end column, which can avoid the on-site tying of steel bars of the shear wall constraint end column, thereby improving the construction efficiency. When the device is connecting wall panels, the reinforcing steel plate needs to be inserted into the slot. During actual construction, the wall panel is lifted by a crane. During this process, the reinforcing steel plate located above needs to be moved down to face the slot located below. If there is a deviation in the docking position between the reinforcing steel plate and the slot, the construction workers need to make multiple adjustments, which is more troublesome to operate.

[0004] Therefore, it is necessary to provide a new steel structure component for connecting the joints of double-leaf cavity composite walls to solve the above technical problems. Utility Model Content
