Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation wall casting, in particular to a thermal insulation shear wall connecting pull-tab assembly. Background Art

[0002] Insulation walls can effectively improve the energy efficiency of buildings, reduce the temperature difference between indoors and outdoors, and enhance the comfort of the living environment. In addition, wall insulation also protects the building structure. The wall insulation layer can reduce the temperature change on the wall surface and reduce the structural contraction and expansion caused by temperature differences, thereby extending the service life of the building, reducing the erosion of external wind, rain and ultraviolet rays, playing a role in waterproofing, anti-corrosion, and anti-aging, and enhancing the durability of the building.

[0003] In the prior art, the materials used for the thermal insulation shear wall are generally foam board, steel wire mesh and steel cage. However, the structure of most of the current cast-in-place concrete shear wall self-insulation systems is relatively simple. The foam board and the steel wire mesh are connected by connecting pull tabs and ties. During pouring, the foam board is prone to position displacement, resulting in poor pouring effect, and the ties are prone to leak out of the pouring layer to produce a cold and hot bridge phenomenon, affecting the wall insulation effect.

The thermal insulation shear wall includes an insulation board 4, a steel mesh 5 and a steel cage 6, the steel mesh 5 and the steel cage 6 are respectively located on the left and right sides of the insulation board 4, and the fixed tab 1 is arranged to penetrate the insulation board 4 from left to right.

[0025] The left side of the fixed pull tab 1 is sleeved with a plastic support positioning member 7, and its structure mainly includes a cylindrical card-shaped limiting plate 71 and a steel wire support block 72 fixedly arranged on one side of the limiting plate 71. A steel wire slot 73 is arranged at the left end of the steel wire support block 72, and the extension direction of the steel wire slot 73 is perpendicular to the extension direction of the fixed pull tab 1. The steel wire on the steel wire mesh 5 on the left side of the insulation board 4 is clamped in the steel wire slot 73. A limiting column 74 is fixedly arranged on the other side of the limiting plate 71, and the length of the limiting column 74 is equal to the thickness of the insulation board 4. The centers of the limiting plate 71, the steel wire support block 72 and the limiting column 74 are on the same axis, and a pull tab passing channel 75 is commonly arranged at the axis.
