A thermal insulation system for exterior walls and its construction method

Abstract

The present application relates to the field of building structures, in particular to an insulation system for an exterior wall and a construction method thereof, including insulation boards bonded to the wall, and there are multiple insulation boards, and the insulation system for the exterior walls also includes connecting plates , the connecting plate is located on the inner side of the ends where two adjacent insulation boards are close to each other, the connecting plate is fixedly connected to the wall, the two ends of the connecting plate in the width direction are fixedly connected to the limit piece, and one end of the limit piece protrudes from the connecting plate close to the heat preservation plate On one side of the insulation board, there is a slot on the inner side of the insulation board, and the limiter is plugged into the insulation board through the slot, and the two adjacent insulation boards are connected to the connecting plate through the limiter and the slot. A sealant is filled between the insulation boards. During use, the limit piece on the connecting plate will reduce the possibility that the ends of two adjacent insulation boards close to each other will move too much in the direction of moving away from each other or approaching each other, so as to improve the distance between the insulation board and the wall. The purpose of the robustness of the connection.

Description

technical field [0001] The present application relates to the field of building structures, in particular to an external wall thermal insulation system and a construction method thereof. Background technique [0002] In the building construction industry, external wall insulation is composed of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board or extruded board and other materials, and is bonded on site. [0003] refer to figure 1 , the thermal insulation system of the external wall includes a thermal insulation board 1 installed on the outside of the wall 6, the thermal insulation board 1 is bonded to the wall 6, the end of the thermal insulation board 1 is plugged with a connector 5, and the connector 5 is fixedly connected to the wall 6 , there are multiple insulation boards 1, and a sealant is filled between the gaps between two adjacent insulation boards 1 . In the process of installing the thermal insulation system of the external ...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, after the external wall insulation system has been used for a period of time, the insulation board 1 will have a slight displacement relative to the wall surface 6 due to wind, impact or deformation. At this time, the distance between adjacent insulation boards 1 The size of the gap will change. When the size of the gap between adjacent insulation boards 1 changes too much, the sealant will crack. In the case of rainfall or relative humidity, water will enter the inner side of the insulation board 1 along the cracks of the sealant, and the heat preservation The adhesive in the board 1 will fail after being soaked in water for a period of time, so that the insulation board 1 is easy to fall off from the wall 6, so the stability of the connection between the insulation board 1 and the wall 6 is poor
