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

Embodiment 1

[0030] A straw-steel composite prefabricated load-bearing wall, the composition of which includes: a steel frame used for assembly, steel wire mesh is arranged on the sides of the two inner walls of the steel frame, and the space enclosed by the steel frame is filled with straw plate, the upper and lower ends of the steel frame have vertical wall interfaces for direct docking, and the left and right ends of the steel frame have wall interfaces for staggered docking.

Embodiment 2

[0032]According to the straw-steel composite prefabricated load-bearing wall described in Example 1, the surrounding steel frame is welded into a rectangular frame by channel steel, and the well-shaped grid formed by welding strip steel plates is welded on the flange of the channel steel. As the side of the steel frame; the flange of the channel steel is welded with a set of hooks, and the steel wire mesh is hung on the hooks close to the well-shaped grid, so that the steel wire mesh plays a restraining and supporting role on the straw board, so that the straw The lateral load on the plate is evenly distributed;

[0033] The wall interface is a group of cuboid interfaces welded on the channel steel. The cuboid interface has an upper groove, and a trapezoidal steel block is arranged in the upper groove, and a spring is arranged under the trapezoidal steel block. The cuboid interface described above also has a lower groove, and when the wall interface is staggered butted, the tr...

Embodiment 3

[0036] In the method for making the above-mentioned straw-steel composite prefabricated load-bearing wall, the surrounding steel frame is welded by light channel steel, the well-shaped grid in the middle is welded by light steel plate, and the end of the straw plate is inserted into the groove of the light channel steel In the process, the groove of the channel steel must be equal to the thickness of the straw plate, and the channel steel is specifically selected as C-shaped steel; the C-shaped steel is set around the straw plate, and the C-shaped steel is welded together; the well-shaped grid is welded to the wings of the C-shaped steel At the edge, the hook is connected to the steel frame in the form of welding, the two ends of the horizontal and vertical steel wires pass through the hook respectively, the steel wire is pulled tight, and then the steel wire goes out of the hook part, folded back and twisted into a twist with the steel wire, so that the steel wire It is fixed ...

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 assembled load-bearing wall and a manufacturing method thereof. Background technique: [0002] For a long time in my country, most of the middle and low-rise building walls have been made of fired clay bricks, but firing clay bricks consumes a lot of land and coal resources, and the random burning of straw is also one of the root causes of smog. The present invention makes full use of this renewable resource of straw As a new green material, it can greatly reduce the consumption of fossil fuels such as coal and the air pollution caused by straw incineration, and the new compacted straw board has high strength, good fireproof and waterproof performance, thermal insulation, light weight, Compared with traditional sintered ordinary brick walls, it can effectively reduce construction waste and environmental pollution. As a new type of wall material, it has obvious advantages in environmental protection and en...
