Straw-steel composite prefabricated load-bearing wall and manufacturing method thereof

Abstract

Disclosed are a straw-steel composite fabricated load-bearing wall and a manufacturing method thereof. At present, most of adopted fabricated composite wall bodies use ordinary concrete as a structural layer, and the thermal insulation performance of the ordinary concrete needs to be improved; a current solution is that fine stone concrete is adopted, while the method takes strength sacrifice as prerequisite, and the most of current concrete composite wall bodies are non-load-bearing wall bodies; and it is the research direction at the present stage to develop a composite wall body which can bear and is good in heat insulation performance. The straw-steel composite fabricated load-bearing wall comprises a steel frame used for assembling, and the two inner wall side surfaces of the steel frame are provided with steel wire nets; a defined space in the steel frame is filled with straw plates, and wall body vertical connecting openings used for direct abutting joint are formed in the upperend and the lower end of the steel frame; and wall body connecting openings used for staggered abutting joint are formed in the left end and the right end of the steel frame.

Description

Technical field:[0001]The invention relates to a straw-steel composite assembly type bearing wall and a manufacturing method thereof.Background technique:[0002]For a long time in our country, the walls of middle and low-rise buildings mostly use sintered clay bricks, and the fired clay bricks consume a lot of land and coal resources, and the random burning of straw is also one of the sources of smog. The present invention makes full use of straw, a renewable resource. As a new green material, it can greatly reduce the consumption of coal and other fossil fuels and the air pollution caused by straw burning. The new compacted straw board has high strength, good fire resistance and waterproof performance, thermal insulation, and light weight. It is easy to install. Compared with the traditional sintered ordinary brick wall, it can effectively reduce construction waste and environmental pollution. As a new wall material, it has obvious advantages in environmental protection and energy s...

Problems solved by technology

[0004] At this stage, a lot of research has been done on the performance of composite wall panels such as wind resistance and earthquake resistance at home and abroad, and some specific theories and formulas have been deduced, but the research results for composite walls are still not comprehensive enough. Energy-saving composite wall panels and The basis and advantage of its promotion is its good thermal insulation performance, but it is difficult to connect the composite wallboard to the steel structure, so it is necessary to choose a scientific node installation method, which can not only ensure excellent thermal insulation performance, but also achieve The basic mechanical performance indicators required by itself

Most of the prefabricated composite walls currently used use ordinary concrete as the structural layer, and the thermal insulation performance of ordinary concrete needs to be improved. The current solution is to use fine stone concrete, but this method is based on the premise of sacrificing strength, and currently Most of the concrete composite walls in the world are non-load-bearing walls, and the development of composite walls that can bear loads and have good thermal insulation performance is the direction of research at this stage
