Thread-off proof fastener for assembling heat preservation and decoration integrated plate, wall body structure and construction method thereof

Abstract

The invention discloses a thread-off proof fastener for assembling a heat preservation and decoration integrated plate, a wall body structure of an exterior wall dried hanging heat preservation and decoration integrated plate using the thread-off proof fastener and a construction method thereof. The thread-off proof fastener comprises a connecting belt, a fixed part, a positioning part and a distance adjusting mechanism. The fixed part is fixed to one end of the connecting belt and used for being embedded into an exterior wall and fixed to the exterior wall. The positioning part is arranged atthe other end of the connecting belt and comprises an upper clamping part, a lower clamping part, an upper positioning plate and a lower positioning plate, wherein the upper clamping part and the lower clamping part extend up and down and are used for clamping into a corresponding heat preservation decoration integrated plate, the upper positioning plate and the lower positioning plate are horizontal, located inside at intervals, and used for attaching to the end face of the corresponding heat preservation decoration integrated plate, and the lower positioning plate remains horizontal with the bottom of the fixed part. The distance adjusting mechanism is provided with a locking structure, the adjusting end of the distance adjusting mechanism is arranged outside the positioning part, and the distance adjusting mechanism connects the positioning part and the connecting belt and can drive the positioning part to move towards the fixed part. The intensity of a wall body is greatly improved.

Description

technical field [0001] The invention relates to the field of building structure systems, in particular to an anti-tripping piece for assembling a thermal insulation and decoration integrated panel, a wall structure of an external wall dry-hanging thermal insulation and decoration integrated panel and a construction method thereof. Background technique [0002] Prefabricated buildings and passive low-energy buildings are two important development directions for building energy-saving and green buildings, and their development prospects are very broad. [0003] Prefabricated buildings are buildings assembled from prefabricated parts on site. In September 2016, the General Office of the State Council issued the "Guiding Opinions of the General Office of the State Council on Vigorously Developing Prefabricated Buildings" (Guo Fa [2016] No. 71), stating that the development of prefabricated buildings is a major change in the construction method, which is conducive to saving resou...

AI Technical Summary

Problems solved by technology

Since the anchors are arranged in the thickness direction of the thermal insulation decorative board, and at least two anchors are placed on each board, there are a large number of thermal (cold) bridges in the building external thermal insulation system, which increases energy consumption

On the other hand, the support of the insulation board is basically a combination of two steel plates. Both steel plates have long round holes. By adjusting the relative position of the long round holes, the insulation boards of different thicknesses can be adapted. Due to the design of the long round holes, only the distance can be adjusted. , can not produce pre-tightening force, so the insulation board cannot become an effective force-bearing body with the base wall, and cannot play a corresponding protective role
