Combination type steel net frame and concrete composite block, and method of making same

Abstract

The present invention discloses a combination type steel net frame and concrete composite block and a method of making same. The invention is invented in order to solve the problem of bad durability, bad intensity, slow in assembly construction and high in cost existing in reinforced concrete structure and steel structure. The structure of the composite block of the invention is that: one side or more sides of the outer surface of a cold bending lattice rolled-steel section backbone is fixed with steel plate or steel plate net composite thermal insulation board, the concrete is filled in the holes of the cold bending lattice rolled-steel section backbone and steel plate net; the fabricating method of the invention is that: fixing more than two cold bending lattice rolled-steel section on a connection member to form the cold bending lattice rolled-steel section backbone; fixing the steel net or steel net composite thermal insulation board on one side or more sides of the outer surface of a cold bending lattice rolled-steel section backbone; filling the concrete into the holes of the cold bending lattice rolled-steel section backbone and steel plate net. The invention has the advantages of durable, high-strength, fast in assembly and construction and low cost, and can be applied to various buildings.

Description

technical field [0001] The invention relates to a building structural component and a manufacturing method thereof, in particular to a building component formed by fixing steel plate mesh on a cold-formed lattice steel frame, a combined steel grid frame and concrete composite, and a manufacturing method thereof. Background technique [0002] In recent years, the production and consumption of steel, cement and red bricks in my country rank first in the world. As we all know, reinforced concrete, especially red bricks, not only benefit the society, but also bring serious resource disasters to the society. Our country mainly develops multi-storey and high-rise residential buildings. Only nearly 50 million tons of steel bars and nearly 150 million tons of cement are used for residential buildings every year. The subsequent clay red bricks and building formwork consume huge resources. It has become an urgent basic national policy to promote energy-saving, water-saving, and land-...

AI Technical Summary

Problems solved by technology

[0007] In recent years, there is also a kind of cold-formed steel with space lattice structure in foreign countries, which is characterized in that there are continuous and large-area holes with flanges on the web of ordinary cold-formed steel, which has high strength, light weight, and good shape. Beautiful, easy to thread and other advantages; its production technology has matured, but the application technology has not changed
