Cold bent lattice type steel and gypsum composite wall and preparing method thereof

Abstract

The invention discloses a cold bent lattice type steel and gypsum composite wall and a preparing method in the technical field of house building. The cold bent lattice type steel and gypsum compositewall is formed by combining a cold bent lattice type steel framework, a steel net, anchor bolts, self-tapping screws or fasteners and gypsum mortar in a spraying building mode. The cold bent lattice type steel framework comprises a vertical stand column and a transverse keel, and the transverse keel is divided into an upper guide rail, a lower guide rail and an interlamination beam when the wall height exceeds specific height. The cold bent lattice type steel framework and a building structure are fixed through the anchor bolts. The steel net is installed on one or two sides of the cold bent lattice type steel framework through the self-tapping screws or fasteners. A machine spraying construction mode is adopted for the gypsum mortar, gaps of the cold bent lattice type steel framework andthe steel net are filled, wrapped, covered and leveled, and an overall seamless wall is formed after hardening and drying. The wall structure system is good in overall performance, and the wall is free of seams overall, firm and free of bulging and has the excellent performance of lightness, high strength, shock resistance, fire prevention, sound isolation, heat insulation, humid adjustment and the like.

Description

technical field [0001] The invention relates to an inner partition wall structure in the field of house construction and a method for preparing the wall body, in particular to a cold-formed lattice steel composite gypsum wall and a preparation method thereof. Background technique [0002] At present, the country is vigorously advocating prefabricated building technology, including prefabricated concrete structures, prefabricated steel structures, and prefabricated wood structures. Masonry technology includes lightweight slats, prefabricated slabs and light steel keel composite walls. Lightweight batten walls include solid or porous strips made of inorganic cementitious materials and aggregates (such as lightweight aggregate concrete strips, autoclaved aerated concrete strips, steel mesh ceramsite concrete strips, gypsum strips etc.), and prefabricated sandwich panels (such as concrete rock wool or polystyrene sandwich panels, fiber cement board lightweight sandwich panels, ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a cold-formed lattice steel composite gypsum wall and its preparation method, through cold-formed lattice steel skeleton, steel mesh, anchor bolts, self-tapping screws or nails, gypsum The integration of mortar and building structure connectors solves the problems of internal partition walls such as poor earthquake resistance, sound insulation, heat insulation performance and easy cracking of walls, and at the same time absorbs a large amount of industrial solid waste
