Anchor for thermal insulation board and construction technology of external wall thermal insulation system using the anchor

Abstract

The invention discloses a heat insulation board anchoring part and an external wall heat insulation system construction technology adopting the heat insulation board anchoring part. The anchoring partcomprises anchoring strips and a chuck detachably connected with each anchoring strip, and each anchoring strip comprises a wing plate as well as a unidirectional clamping belt and a web which are respectively arranged on the upper end face and the lower end face of the wing plate. The construction technology comprises the following steps: smearing a leveling layer on a wall body basement layer;pressing multiple anchoring strips into the leveling layer; fixing the anchoring strips by adopting steel nails; smearing a waterproof layer on the leveling layer; smearing a binding agent layer on the waterproof layer, and covering the unidirectional clamping belts of the anchoring strips with a heat insulation board, so that the heat insulation board is fixed; covering each unidirectional clamping belt with one chuck; smearing one anti-crack mortar layer with the outer end face flushed with the chucks on the heat insulation board, and pressing in glass fiber grid cloth. The heat insulation anchoring part and the external wall heat insulation system construction technology adopting the anchoring part have the advantages that the heat insulation board is firmly mounted, wall body heat insulation effect is good and construction period is short.

Description

technical field [0001] The invention relates to an exterior wall insulation construction technology, in particular to an insulation board anchor and an exterior wall insulation system construction technology using the anchor. Background technique [0002] At present, the insulation system of exterior wall panels is widely used in my country. The construction method is: first apply a thin layer of plastering and leveling layer (generally 20mm thick) on the base of the wall, and then paste the insulation board on the wall with adhesive On the wall, in order to ensure the firmness of the insulation board, it is necessary to use an impact drilling machine to drill holes according to relevant specifications, then plant plastic expansion rivets to fix them, and finally apply a layer of anti-cracking mortar and press into the glass fiber mesh. After adopting the above fixing method, there will be the following problems: 1. When the anchor bolt is installed and drilled, the adhesive ...

AI Technical Summary

Problems solved by technology

After adopting the above fixing method, there will be the following problems: 1. When the anchor bolt is installed and drilled, the adhesive between the insulation board and the wall will be vibrated, so that the insulation board and the adhesive will fall off; 2. The position of the anchor bolt will form a rigid fulcrum, which will affect the insulation expansion and deformation of the board; 3. Drilling holes on the finished wall may also affect the waterproof function of the external wall insulation system; 4. The hammering when fixing the rivets may make the plastic anchor tray easy to deform, and the anti-crack mortar layer is easy to deform. Form raised points, affect the flatness of the wall
