Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation walls, in particular to a pull rod assembly for a built-in thermal insulation shear wall. Background Art

[0002] Shear wall insulation is a common building insulation material. Its main function is to improve the thermal insulation performance of buildings, reduce energy consumption, and improve indoor comfort. Shear wall insulation is usually filled with materials such as polystyrene, polyurethane foam or rock wool inside the building wall. These materials have good thermal insulation performance and durability, can effectively insulate and preserve heat, reduce energy loss, and improve the energy efficiency of buildings.

[0003] As a common building insulation technology, shear wall insulation plays an important role in improving building energy efficiency, improving indoor comfort, saving energy and protecting the environment. With the improvement of people's awareness of energy conservation and environmental protection and the support of relevant policies, shear wall insulation will have broader application prospects in the future.

[0004] During the construction of the insulation shear wall, a supporting structure is required to fix the insulation material. Otherwise, the insulation material is prone to displacement, resulting in uneven coverage, which not only delays the construction speed but also reduces the construction quality. Therefore, a tensioning support device is needed to fix the insulation material to improve the construction quality. Utility Model Content
