Self-resetting connecting joint between steel frame and composite wallboard and fabricated building thereof

Abstract

The invention provides a self-resetting connecting joint between a steel frame and a composite wallboard and a fabricated building thereof. The composite wallboard connecting joint comprises the steel frame, the composite wallboard and a self-resetting connecting piece. The composite wallboard is arranged on the frame through the plurality of self-resetting connecting pieces; the self-resetting connecting piece comprises a middle cylinder body; the cross section of the middle cylinder is in a long circle shape, and the middle cylinder comprises two straight line sections arranged in parallel and two arc sections symmetrically arranged on the two sides. And the middle barrel is fixedly connected with the frame and the composite wallboard through the two linear sections respectively. According to the structural form of the self-resetting connecting piece, energy can be effectively absorbed and consumed, the self-resetting connecting piece has certain self-resetting capacity, particularly, residual deformation of the structure after unloading in the early stage is basically zero, and residual deformation of the structure after loading is still small. And the permanent damage of the structure can be effectively reduced through reduction of residual deformation, the loss of the structure is reduced, and the repairability of the structure is improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a self-resetting connection node between a steel frame and a composite wall panel and an assembled building thereof. Background technique [0002] Prefabricated buildings have been widely popularized and applied due to their high efficiency and ease of implementation. However, there are the following deficiencies or defects between the frame and the wall of the existing prefabricated building: [0003] (1) The traditional steel frame embedded RC shear wall structure has many consumables, heavy self-consumption, high construction cost, and high maintenance cost after the structure is damaged. [0004] (2) Although the traditional concrete sandwich wall has good thermal insulation performance, when the concrete cladding is thin, it mainly exhibits the characteristics of non-structural components similar to the infill wall, and the mechanical properties such as bearing capacit...

AI Technical Summary

Problems solved by technology

[0003] (1) The RC shear wall structure embedded in the traditional steel frame has many consumables, heavy weight, high cost, and high maintenance cost after the structure is damaged

[0004] (2) Although the traditional concrete sandwich wall has good thermal insulation performance, when the concrete cladding is thin, it mainly shows the characteristics of non-structural components similar to the filling wall, and the mechanical properties such as bearing capacity and stiffness are average; thicker concrete cladding is used When its own weight is larger

[0005] (3) The research on the structural system of frame-supported densely ribbed composite wall mainly focuses on the synergistic structure of reinforced concrete frame and densely ribbed composite wall. Connector performance research

In addition, the traditional frame-supported dense-ribbed composite wall panel structure adopts an embedded structure, and when it is combined with a steel frame to form a synergistic structure, the frame columns are exposed, which is not conducive to the corrosion resistance of the steel structure and affects the durability of the structure

[0006] (4) Under the action of load, the residual deformation of the connection node is relatively large, it does not have the ability of self-resetting, and to a certain extent, it cannot meet the requirements of large deformation of the structure, etc.
