Description

Technical Field

[0002] The installation and application of insulation boards play an important role in energy conservation and emission reduction, pollution reduction, and extension of building service life in construction projects. The traditional insulation board installation process is mainly pasting, "pasting the insulation board to the wall through bonding glue" and supplemented by anchoring, "drilling holes on the wall where the insulation board is pasted and implanting insulation nails". This process has been used since its birth, but the problems existing in the process have not been solved: first, pasting is the main method, the quality of the bonding glue is uncontrollable, and the construction process is uncontrollable, which will cause weak bonding and cause the insulation board to fall off; second, anchoring is supplemented, and the effectiveness of anchoring depends on the strength of the insulation nail, expansion method, wall type, wall strength and other constraints and restrictions. For example: before this, there was no insulation nail suitable for all wall structures, so whether the insulation nail anchoring is effective also determines the quality of a project.
