A construction method for an anti-falling-off building external thermal insulation structure

Abstract

The invention relates to a construction method of a falling-off prevention building outer heat preservation structure. The falling-off prevention building outer heat preservation structure comprises afirst reinforced layer, a bonding mortar layer, a second reinforced layer, a reinforcing bonding layer, a heat preservation and heat insulation layer, a bonding anti-cracking layer, a water insulation layer and a decorating layer which are arranged sequentially on the outer side of a building outer wall. Built-in bolts are pre-arranged inside the falling-off prevention building outer heat preservation structure and connected with anchoring connection screw rods; a vertical connecting groove is formed in the outer surface of the building outer wall and internally provided with a reinforcing bonding body; vertical reinforced belts and post-injected glue are arranged between the reinforcing bonding layer and the heat preservation and heat insulation layer; a plane pressing strip and a cornerpressing strip are arranged on the outer side of the heat preservation and heat insulation layer; and the vertical reinforced belts, second glue injecting pipes, the plane pressing strip and the corner pressing strip are all connected with the anchoring connection screw rods. According to the construction method of the falling-off prevention building outer heat preservation structure, the connecting strength between an outer heat preservation layer and a cast-in-situ concrete wall body can be improved, the outer heat preservation layer is prevented from cracking and falling off, and the difficulty of disease treatment is lowered.

Description

technical field [0001] The invention relates to an external thermal insulation structure of a building, in particular to a construction method for an anti-falling external thermal insulation structure of a building that can effectively enhance structural integrity and prevent structural cracking, belongs to the field of construction engineering, and is suitable for external thermal insulation structures of thermal insulation slurry and thermal insulation boards External thermal insulation structure engineering. Background technique [0002] At present, the external wall insulation methods used in buildings mainly include internal insulation, external insulation, and internal and external hybrid insulation. Among them, compared with internal insulation, external thermal insulation has the characteristics of good thermal insulation structure continuity and little impact on building decoration, and is more widely used. However, from the perspective of engineering application, ...

AI Technical Summary

Problems solved by technology

Although the thermal insulation system can prevent and control the cracking and falling off of the thermal insulation layer induced by the external temperature difference to a certain extent, it is difficult to effectively strengthen the connection between the thermal insulation layer and the outer wall, and cannot block the infiltration channel of rainwater, so it is difficult to overcome the uneven stress problem of the thermal insulation structure layer

[0004] To sum up, the existing external thermal insulation structures and construction methods of building external walls have achieved good application results in suitable environments, but in terms of improving the bonding performance between building external walls and thermal insulation materials, enhancing structural integrity, and local There are still areas for further improvement in the prevention and control of uneven stress
