Back bolt dry hanging structure of stone curtain wall and construction method thereof

Abstract

The invention discloses a back bolt dry hanging structure of a stone curtain wall and a construction method thereof. The stone curtain wall comprises a stone face plate and back bolt implanting holes formed in one side facing the interior of the stone face plate in a dry hanging state. The back bolt dry hanging structure comprises back bolt bodies. One ends of the back bolt bodies are implanted into the back bolt implanting holes, and the other ends of the back bolt bodies lean out of the back bolt implanting holes and are connected with an adapting mechanism in the dry hanging state. The back bolt dry hanging structure has the characteristics that the back bolt dry hanging structure further comprises stone face plate crazing-preventing reinforcing plates fixed to the inward-facing side of the stone face plate, and back bolt place-giving holes are formed in the stone face plate crazing-preventing reinforcing plates; one ends of the back bolt bodies are locked by back bolt locking nuts matched on the back bolt bodies in a screwed mode; and the other ends of the back bolt bodies lean out of the back bolt place-giving holes are connected with the adapting mechanism. Breakthrough preventing and crazing preventing capacity of the back portion of the stone face plate is strengthened; the requirement of horizontally hanging the downward-facing side of the top of a building gallery is met; the structure is simple and low in cost; and the construction method is simple and convenient to operate, the construction cost is not increased, and the technical effect of the back bolt dry hanging structure can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building wall decoration, and in particular relates to a back-bolt dry-hanging structure of a stone curtain wall, and also relates to a construction method thereof. Background technique [0002] Stone curtain walls are widely used in the architectural decoration industry because of their simple elegance, natural atmosphere, heat insulation, noise reduction, and the ability to significantly improve the visibility of buildings and not bear the load of the main structure of the building. There is no shortage of technical information about stone curtain walls in the disclosed Chinese patent documents, such as document A.CN203160475U recommending "a kind of removable back-bolt type stone curtain wall"; document B.CN103452214B provides "back-bolt stone curtain wall"; document C.CN105672539A introduces "a stone back bolt pendant and its use method"; document D.CN106013543A discloses "a hanging back bolt structur...

AI Technical Summary

Problems solved by technology

Since the thickness of the currently commonly used stone panels is usually 25mm, the strength of the stone panels in the holes where the back bolts are implanted is relatively weak and even cracks may exist. , then there is no doubt that it will affect the dry hanging effect and even cause accidents due to the falling of the stone panel

There is another situation: during the process of handling and installation, when the back bolt is touched, especially the back bolt that has been implanted in the hole of the back bolt is touched, the back bolt is easy to loosen, and even the stone panel will appear tortoise around the back bolt in a chain reaction. In the case of cracks, when the back bolt is loose, the anchoring force during dry hanging is significantly reduced

There is another situation: because the stone plate will produce expansion
