All-prefabricated rapid assembly type light-steel-keel load-bearing composite wall

Abstract

The invention discloses an all-prefabricated rapid assembly type light-steel-keel load-bearing composite wall comprising square steel tube columns, an upper guide rail, a lower guide rail and wall units. The guide rails are U-shaped light-steel guide rails with flanges and webs, and the wall units are slidably arranged in a frame formed by the square steel tube columns at two ends and the upper and lower U-shaped light-steel guide rails in a filling manner. The wall units are prefabricated load-bearing members, each wall unit is composed of a pair of wall panels and a light gage steel joist stud and a heat insulation filling material clamped between the wall panels, parallel sliding grooves are formed between the inner sides of the wall panels at the top end and the bottom end and the heat insulation filling material as well as between the inner sides of the wall panels and light gage steel joist stud, and the parallel sliding grooves are in slide fit with the upper and lower guide rails; the flanges of the upper and lower guide rails are connected with the light gage steel joist studs in the wall units through bolts, and the guide rails are connected with the square steel tube columns through screws. The all-prefabricated rapid assembly type light-steel-keel load-bearing composite wall is few in variety of built-up members, lightweight, steel-saving, capable of realizing heat and sound insulation and applicable to low and multi-story building load-bearing wall systems, wet construction and the welding process on a construction site are omitted, large hoisting equipment is omitted, and quick all-prefabricated assembly construction can be achieved.

Description

Technical field [0001] The invention relates to an assembled building structure, in particular to a fast construction, fully prefabricated assembly type light steel keel load-bearing composite wall structure, and belongs to the technical field of civil engineering. Background technique [0002] Compared with the traditional reinforced concrete structure, the steel structure has the characteristics of environmental protection, good seismic performance, fast construction speed, and recyclable materials. With the rapid development of the national economy, my country's steel output has become the world's first, and the domestic steel structure industry has also developed rapidly. However, compared with developed countries, the proportion of steel structures in my country’s steel output is still significantly lower. At the same time, my country’s building structures are energy-saving and consumption-reducing (recyclable), industrialized production, and large-scale enterprise group ope...

Problems solved by technology

Each sandwich wall panel unit includes A-side and B-side wall panels, and between the A-side and B-side wall panels, there are autoclaved aerated concrete slats and thermal insulation cotton, which are adjacent on the same side The sandwich wall panel unit is spliced ​​by inserting autoclaved aerated concrete butt joints in the grooves of its long sides, which realizes the prefabricated assembly of the firewall body, but still requires a large number of self-supplied screws, and the installation process is cumbersome
