Lightgage steel joist composite wall body and construction technology

Abstract

The invention discloses a lightgage steel joist composite wall body which comprises a joist and face plates on the two sides of the wall body. The joist comprises a ground horizontal joist, a top horizontal joist, a column joist and vertical joists. The vertical joists are evenly arranged between the face plates. Each vertical joist comprises two vertical steel plates and a plurality of horizontal steel plates evenly arranged between the vertical steel plates. Bridge cutoff cushion blocks are arranged between the vertical joists and the face plates. Cross-brace joists are arranged between the vertical joists. The cross-brace joists and the vertical joists are connected through angle brackets. Gaps of the vertical joists are large, concrete circulating can be well achieved, construction difficulty is lowered, and the construction schedule is accelerated. The invention further provides a construction method of the composite wall body. The method is suitable for transforming, expanding and rebuilding a civil building and is suitable for an inner partitioning wall and an outer partitioning wall, the construction procedure is standardized, construction speed is accelerated, so that building of the composite wall body is reasonable, and the building quality of the composite wall body is improved.

Description

technical field [0001] The invention relates to the technical field of keel composite walls, in particular to a light steel keel composite wall and a construction process. Background technique [0002] In the current construction, the light steel keel composite wall uses the thin-walled C-shaped steel keel as the main support, and the inorganic panels are fixed with screws or other fixing parts on the inner and outer sides of the keel. A cavity is formed between the two side panels, and the foam concrete slurry is poured into the cavity, and the insulating core layer is formed after hardening. Between the panel and the keel, a bridge break pad is set. In this way, with the keel as the support, the panel as the surface layer, and the foam concrete as the core layer, a new type of composite wall with a more reasonable structure is formed. This kind of composite wall is mainly used in the inner partition wall of high-rise frame structure buildings, and a small amount is used ...

Problems solved by technology

Among them, the prefabricated wall panels form a cavity between the prefabricated wall panels as a formwork for the closed space during pouring. After the wall is constructed, the surface of the prefabricated wall panels is directly used as the wall surface without other plastering operations, which simplifies The wall construction process is completed, but the reserved opening is too small, the fluidity of the concrete is not particularly good, it is easy to cause an increase in the construction time and even a cavity that is not filled with concrete inside the wall, which reduces the quality of the construction

[0005] The utility model with the publication number of 201321667 discloses an inorganic light steel composite wall. The chord of the wall is fixed by a W-shaped or V-shaped connector, which is also not conducive to the flow of concrete during pouring and reduces the construction quality.
