Description

Technical Field

[0001] This application belongs to the technical field of prefabricated buildings, and particularly relates to a precast membrane shell wall member. Background Art

[0002] Precast membrane shell wall members are a type of prefabricated material widely used in the construction field. Currently, for the formation of the framework of precast membrane shell wall members, a three-dimensional variable body stress-bearing framework structure is adopted, and the upper chord or lower chord steel bars in the framework structure do not bear the structural stress-bearing steel bars of the membrane shell wall. There are displacements, looseness, and instability between the membrane shell wallboard structures on both sides of the membrane shell wall, which is uneconomical and inconvenient for industrialized and large-scale factory production. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide a precast membrane shell wall member, which can solve at least one of the technical problems involved in the background art.

[0004] To solve the above technical problems, this application is implemented as follows:

[0005] The embodiments of this application provide a precast membrane shell wall member, including a first cement board and a second cement board that are relatively spaced apart, and a stress-bearing framework structure disposed between the first cement board and the second cement board. Metal meshes are embedded in both the first cement board and the second cement board. The stress-bearing framework structure includes a footless planar truss and a footed truss that is cross-fixed with the footless planar truss. The footed truss includes feet fixed to the first cement board and the second cement board.

[0006] Optionally, the footless planar truss is located between the first cement board and the second cement board and is spaced apart from the first cement board and the second cement board.

[0007] Optionally, the number of the footed trusses is multiple, and the multiple footed trusses are spaced apart from each other.

[0008] Optionally, the footed truss fixed to the first cement board and the footed truss fixed to the second cement board are arranged alternately.

[0009] Optionally, the footed truss and the footless planar truss are arranged cross-parallel at an interval of 90 degrees.

[0010] Optionally, the cross-section of the intersection of the footed truss and the footless planar truss is triangular or "one"-shaped.

[0011] Optionally, the footed truss is a footed triangular truss or a footed planar truss.

[0012] Optionally, the footed truss and the footless planar truss are fixed by welding.

[0013] Optionally, the feet of the truss with feet are fixedly connected to the wire mesh without angular displacement.

[0014] Optionally, the wire mesh is a steel wire mesh.

[0015] The present application has the following beneficial effects compared with the prior art:

[0016] 1. By setting a stress skeleton structure including a footless plane truss and a truss with feet cross-fixed to the footless plane truss, a large amount of steel bar material consumption is reduced, and large-scale factory production can be achieved, reducing labor costs;

[0017] 2. The cement board surface of the membrane shell wall does not need to be plastered, thereby reducing material consumption and labor;

[0018] 3. The contact surface between the membrane shell wall and the main structure is made into an inclined rough surface, reducing cracking at the joint and improving the project quality. BRIEF DESCRIPTION OF THE DRAWINGS
