Anti-crack net for wall

Abstract

The invention relates to a wall anti-crack network, which is characterized in that: several parallel folded steel wires are arranged whose folded edges are the same; the inner angle of nearby folded edges is 120degrees; and the nearby folded edges are welded. The invention can keep stable state of thermal-insulated wall, improve its anti-crack property.

Description

Technical field: [0001] The invention relates to building materials, in particular to an anti-crack net for walls. Background technique: [0002] We know that external wall insulation is one of the main measures for energy-saving buildings, and cracks in the external wall insulation layer are serious problems in the quality of thermal insulation buildings. Crack resistance is one of the key technologies to be solved by the wall insulation system. Because once the thermal insulation layer cracks, the thermal insulation performance of the wall will change greatly, not only failing to meet the energy-saving requirements of the design, but even endangering the safety of the wall. The existence of cracks in the thermal insulation wall reduces the quality of the wall, such as the overall performance, thermal insulation, penetration resistance and earthquake resistance, as there are more and more disputes or lawsuits involving cracks in the thermal insulation wall of residential pr...

Problems solved by technology

[0003] The grid insulation board currently used is equipped with a steel wire mesh on the insulation board. The steel wire mesh is welded vertically by radial wires and weft wires. The radial wires and weft wires form a quadrangular shape. , the cracks in the actual thermal insulation project mostly occur along the diagonal direction of the mesh, mainly because the four-angle steel mesh has a good effect on low resistance and dispersing the stress in the same direction as the steel mesh mesh, but in the diagonal direction of the mesh There is no rib in the line direction, the length of the diagonal line is 1.14 times the length of the side, and the difference in the length of the holes is too large. When the steel wire mesh is subjected to stress in all directions, the force (c-c` and d-d`) in the diagonal direction is the least tensile. , the effect of resisting and dispersing the stress in the diagonal direction of the mesh is very limited, and it is very easy to generate cracks along the diagonal of the square mesh. In addition, the square steel mesh is welded by radial wires and weft wires vertically, and If the diameter wire and the weft wire are superimposed together, the cement mortar is not easy to complete the full throw, so that the mortar and the steel wire mesh cannot become a common force-bearing body
