Flexible Steel Frame—Prefabricated Recycled Concrete Wall Panel and Manufacturing Method

Abstract

The invention discloses a flexible steel framework-prefabricated assembling type recycled concrete wallboard. The flexible steel framework-prefabricated assembling type recycled concrete wallboard comprises a steel framework, wherein the steel framework is formed by connecting a steel beam between a pair of steel columns; a column reinforcing rib is arranged on each steel column; the column reinforcing ribs are located at the corresponding positions of the steel columns and the steel beam; end plates are arranged at the two ends of the steel beam respectively, and are connected with the pair of steel columns by node connection bolts; the bottom of the steel beam is connected with a lug plate and the lug plate is connected with a T-shaped piece by a lug plate reinforcing rib; the bottom end of the T-shaped piece is connected with a plurality of U-shaped ribs; the T-shaped piece and the U-shaped ribs are pre-buried in a recycled concrete wallboard; the recycled concrete wallboard is connected with the lug plate by a connection piece bolt; and a steel rib net piece is further arranged in the recycled concrete wallboard, and the steel rib net piece is connected with the T-shaped piece. A manufacturing method comprises the step of connecting all the parts according to a connection relation and a position relation. According to the structure system, the framework is cooperated with a wall body, the lateral rigidity resistance and the bearing capability are improved and the anti-seismic property is good; and the flexible steel framework-prefabricated assembling type recycled concrete wallboard has a simple structure, saves energy and is environmentally friendly, and standardized construction is facilitated.

Description

technical field

[0001] The invention belongs to the technical field of building wall panels, and in particular relates to a flexible steel frame-prefabricated assembled recycled concrete wall panel, and also relates to a manufacturing method of the wall panel. Background technique

[0002] Steel structure buildings have been more and more widely used and recognized for their good seismic performance, light weight, and fast construction speed. Due to the immaturity of the connection form of beam-column joints and the supporting wall panel system, the development of steel structures is limited to a certain extent. The beam-column joint form commonly used in current engineering is a rigid joint mainly with bolted and welded joints. Due to the insufficient rotation capacity of the rigid joint, brittle cracks are prone to occur at the joint of the lower flange of the beam-column under strong earthquakes, and sometimes even extend to In the flange of the column, the post-earthqua...
