A slidable connection node structure between wall panels and steel beams and its construction method

Abstract

The invention provides a slidable connection node structure between a wall panel and a steel beam and a construction method thereof. The connection node structure includes a steel beam, a wall panel and a connector, the steel beam includes an upper flange, a web and a lower flange, and the connector It includes two L-shaped embedded parts. One end of the L-shaped embedded part is a free end, and the other end is a connecting end. The connecting ends of the two L-shaped embedded parts are connected to one end of a sleeve. The other end is connected with a bolt passing through the lower flange. The two bolts are symmetrically arranged on both sides of the web, and the connection between the bolt and the lower flange is a long round hole. Two L-shaped embedded parts and corresponding sleeves All are pre-buried in the wall panel, and the wall panel is connected with the lower flange of the steel beam by bolts passing through the oblong hole on the lower flange and connecting with the corresponding sleeve. In the present invention, when the building is subjected to a horizontal load, the entire wall panel slides in the length direction of the steel beam, avoiding the participation of the rigid wall panel in resisting the horizontal load, and ensuring that the stress mode of the structure matches the design intention.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a slidable connection node structure between a wall panel and a steel beam and a construction method thereof. Background technique [0002] As an ideal form of green building, prefabricated building is one of the main development directions of my country's construction industry, especially residential buildings. Although the traditional steel structure buildings have realized the prefabrication of structural components, there are still problems such as relatively complicated design process and a large number of on-site welding in the construction process, which consume energy and time. In recent years, a prefabricated steel structure system that separates the anti-gravity system and the anti-lateral force system has effectively solved the above problems: the beam-column joints are all hinged, and only resist the effect of vertical loads. The hinged connection not onl...

Problems solved by technology

For the above-mentioned separable structural system of anti-gravity and lateral force systems, if the outer wall panels with high rigidity participate in the structural stress, it will undoubtedly have a great impact on the overall stress model of the structure, making the structure unable to Carry loads in the manner envisioned by design
