Reinforced structure, system and method of back-bolt type stone curtain wall mounting joint

Abstract

The invention relates to the technical field of installation projects of stone curtain walls, in particular to a reinforced structure, system and method of a back-bolt type stone curtain wall mountingjoint. A groove with the bottom expanding is formed in the back surface of a panel body of the joint reinforced structure, and a prefabricated shim is installed between a back bolt and the groove, the load bearing on the front surface of the panel body changes from the interaction between the original back bolt and a thinner panel on the front surface of the groove to the interaction between theback bolt and the prefabricated shim. The load to be borne depends on the high tensile strength of the shim, the bearing load is transmitted to the back surface of the panel to reduce the impact stress and shear stress between the back bolt and the panel body, so that when larger load is applied on a curtain wall assembly system, the prefabricated shim can be used for avoiding direct contact between the back bolt and the panel body, and the generation of stress concentration problem is reduced. The joint reinforced method can simplify the technological process, improves the efficiency and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of stone curtain wall installation engineering, in particular to a reinforcement structure, system and method for a back-bolt type stone curtain wall installation connection point. Background technique [0002] With the development of the construction industry, building decoration materials can be described as a hundred flowers blooming, and various building decoration materials have sprung up like mushrooms. Among them, stone, with its unique advantages of being natural, heavy, luxurious, etc., makes the style of the buildings built with stone be dignified, luxurious, simple and natural, or magnificent, all of which produce shocking momentum and colorful colors. The infinite changes of nature are contained in abstraction. [0003] At present, the stone curtain wall has attracted many people who pursue the sense of the times and art with its elegant external shape, thus improving the overall urban landscape...

AI Technical Summary

Problems solved by technology

The back bolt type stone curtain wall is generally connected to the stone panel with the back bolt as the connector. When the load is controlled by the wind load, the shear failure of the stone surface is likely to occur at the joint between the back bolt and the hole groove.

This situation is mainly due to the "hard" contact between the metal back bolt and the notch of the stone panel, which leads to the problem of stress concentration at the contact part. At the same time, due to the low shear strength of the stone panel, the groove of the stone panel Mouth prone to shear failure
