Description

Technical Field

[0001] This application relates to the technical field of thermal insulation materials, and in particular to a novel straw thermal insulation wall. Background Technology

[0002] Insulated walls are typically made by installing insulation boards on one side of the wall. The insulation boards are usually made of materials with low thermal conductivity to reduce heat conduction. At the same time, the closed pore structure inside the insulation board prevents air convection and reduces heat convection transfer. In addition, the insulation board has the function of reflecting and absorbing heat radiation, further enhancing the insulation effect.

[0003] When installing insulation boards on a wall, it is usually necessary to align the bolt holes on the insulation board with the bolt holes on the wall. Workers manually limit the position of the insulation board and install it on the wall with bolts. This can easily cause inconvenience in the installation of insulation boards, which in turn has an adverse impact on construction efficiency. Utility Model Content
