Bottom-bearing connection structure for external wall panels of assembled steel structure

Abstract

The invention discloses a bottom-bearing connection structure for external wall panels of an assembled steel structure, and relates to the technical field of architectural structures. T-shaped steel and angle steel are slidably connected with an upper wall panel and a lower wall panel in a vertical friction mode through connecting components respectively, and the upper flange and the lower flange of a steel beam are slidably connected with the T-shaped steel and the angle steel in a horizontal friction mode through high-strength bolt groups respectively; the angle steel is suspended below the lower flange of the steel beam and conducts limiting adjustment of hanging and pulling on the upper wall panel, the T-shaped steel is located above the upper flange of the steel beam, the T-shaped steel extends into the seam of the wall panels, a steel plate above the seam is buried in advance, and the T-shaped steel is used for lifting the upper wall panel; composite floor slabs are anchored to the upper flange of the steel beam through welding studs and supported by the steel beam. According to the bottom-bearing connection structure for external wall panels of the assembled steel structure, the T-shaped steel is used for supporting the wall and bearing the weight of the wall, which is in good accordance with a wall panel bottom-bearing force model. Under the action of an earthquake, the connecting components and the high-strength bolt groups can relatively slide in the vertical holes and horizontal holes of the T-shaped steel and the angle steel, consuming and loading energy to protect the wall panels, and achieving the functions of dissipating the earthquake energy and reducing structural earthquake responses.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a connection structure for an externally hung wall panel of an assembled steel structure. Background technique [0002] Assembled steel structure is a common structural system in modern buildings. Its structural components are transported to the site after being processed in the factory, and are connected by high-strength bolts and welding. It has the advantages of less on-site workload, fast construction speed, and light weight. The function of small earthquake action. Each process on the construction site can be operated in a three-dimensional manner, which further improves construction efficiency and shortens the construction period. [0003] Composite wall panels are widely used in steel structure residential systems. Compared with ordinary wall materials, composite wall panels have the advantages of high bearing capacity, good thermal insulation and sound insul...

Problems solved by technology

However, under the action of an earthquake, the wall panels in this structure will jointly resist the horizontal shear force with the steel frame, and at the same time bear the wind load, and generate displacement to a certain extent, which will inevitably cause damage and destruction of the connecting nodes, resulting in the durability of the connecting parts. reduce, which in turn causes partial wall panels to fall off, and there is a certain degree of potential safety hazard
