Description

Technical Field

[0001] This utility model belongs to the field of building technology, specifically relating to a building exterior wall insulation structure. Background Technology

[0002] Building insulation is a measure to reduce the loss of heat from the interior of a building to the exterior, playing an important role in creating a suitable indoor thermal environment and saving energy. Building insulation mainly involves measures taken on the building's external envelope to reduce the loss of heat from the interior to the exterior, thus playing a crucial role in creating a suitable indoor thermal environment and saving energy.

[0003] Insulation boards are an indispensable part of building insulation. To improve the strength of insulation boards, it is necessary to hang mesh or directly composite steel wire mesh on the outside of the insulation boards. However, the operation is relatively complicated. For example, it is necessary to tie the web wires on site, which is time-consuming and labor-intensive. Traditional steel wire mesh non-removable formwork consists of insulation boards and steel wire mesh. The steel wire mesh is arranged on the outside of the insulation board and the insulation board and steel wire mesh are fixed together by multiple connecting steel wires. However, since both ends of each connecting steel wire are welded to the steel wire mesh, the welding process brings a huge workload to the workers during temporary on-site construction or production, increasing the labor intensity of the workers.

[0004] Furthermore, when assembling traditional wire mesh insulation layers, the end faces are directly connected. During the subsequent pouring process, the wire mesh insulation layer is prone to displacement when poured in a loosely fixed state, which is not conducive to construction.

[0005] In view of the above factors, this utility model provides a building exterior wall insulation structure in which the exterior wall insulation board and connectors are prefabricated, and the steel wire mesh frame is integrally spliced ​​and welded to the connectors. The modular design facilitates on-site operation, saves on-site installation time, and improves work efficiency. Utility Model Content
