A curtain wall glass peripheral structure

Abstract

The invention provides a curtain wall glass peripheral structure comprising an upright column, a cross beam and glass arranged on the outer side of a supporting frame formed by the upright column and the cross beam. The edges of the glass are fixedly connected with corrugated plates through structural glue, through holes are formed in the crests of the corrugated plates, the glass is fixed to the outer side of the supporting frame in the mode that screws penetrate through the through holes, and the corrugated plates of the two adjacent pieces of glass are meshed. The glass is fixed to the supporting frame through the meshed corrugated plates. Firstly, the defect that according to a traditional hidden frame, the glass is attached to a metal framework through structural glue, the structural glue is prone to losing efficacy, and the glass falls off is avoided. Moreover, a gap exists between the adjacent pieces of glass through the meshed corrugated plates, when the glass is heated and expands, generated stress is released into the gap, the glass can not be affected by the stress, and in other words, the situation that the when glass is heated and expands, the glass is easily broken is avoided.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a curtain wall glass peripheral structure. Background technique [0002] The glass curtain wall is a new type of wall in the contemporary era. The biggest feature it gives to the building is the organic unity of architectural aesthetics, building functions, building energy efficiency and building structure. The building presents different tones from different angles. , Moonlight, and light changes give people a dynamic beauty. [0003] Among them, the hidden frame glass curtain wall is to bond the glass to the aluminum frame with silicone structural sealant, and in most cases, no metal connectors are added. Therefore, the aluminum frame is all concealed behind the glass, forming a large-area all-glass mirror surface, which makes the overall building more beautiful. [0004] However, this kind of hidden frame glass curtain wall is completely bonded by structural glue...

Problems solved by technology

[0004] However, this kind of hidden frame glass curtain wall is completely bonded by structural glue between the glass and the aluminum frame. The structural glue must bear the weight of the glass, the wind load and the earthquake effect of the glass, and the curtain wall is affected by the unfavorable factors of the natural environment for a long time. , the structural adhesive is easy to age and fail, causing the glass curtain wall to fall

Therefore, the hidden frame curtain wall is still not widely used, and most curtain wall buildings use exposed frame or semi-hidden frame glass curtain wall. Even if the structural glue fails, due to the support and constraints of the frame, the chance of glass falling will be greatly reduced

[0005] However, when the glass curtain wall with open frame or semi-hidden frame is used, the glass will expand when heated. If the heating is uneven, tensile stress will be generated inside the glass. When there are small cracks on the edge of the glass, these small flaws are easily affected by thermal stress. Eventually lead to glass breakage

In some projects, there are also vertical glass curtain walls with hidden frame curtain walls with metal connectors. Metal fasteners can be used as safety measures, but it is easy to break the glass due to concentrated stress
