Dry type seal structure of glass curtain wall without vertical frames

Abstract

The invention provides a dry type seal structure of a glass curtain wall without vertical frames. The dry type seal structure of the glass curtain wall without the vertical frames comprises a plurality of beams and glass panels between neighboring beams; sealing rubber strips are arranged inside the gaps between transverse neighboring glass panels; every sealing rubber strip comprises a strip body, the head end and the middle portion of the strip body are arranged inside the corresponding gap between the glass panels, and the fin at the tail end of every sealing rubber strip is exposed outside the glass panels and is tightly adhered to the glass panels to seal the gap between the glass panels; the outside of every beam is provided with a press board for pressing the corresponding glass panels, and a covering belt is arranged outside every press board; the contact surface of every beam and the corresponding press board is provided with a groove to form a first water drainage hole, and the bottom of the corresponding covering belt is provided with a second water drainage hole. The dry type seal structure of the glass curtain wall without the vertical frames can achieve rain curtain type water drainage, airtight requirements can be met simply by applying glue onto the outside of the head end of the indoor side of every sealing rubber strip, accordingly onsite glue injection amounts can be greatly reduced, and the quality of curtain wall systems can be improved.

Description

technical field [0001] The invention belongs to the technical field of glass curtain walls, in particular to a dry sealing structure of a glass curtain wall without a mullion. Background technique [0002] "Technical Specifications for Glass Curtain Wall Engineering" JGJ102-2003 mentions that the glass curtain wall supported by a metal frame around the glass panel can be divided into: 1) exposed frame glass curtain wall, 2) hidden frame glass curtain wall, 3) semi-hidden frame Glass curtain wall. This division is based on whether the vertical or transverse members of the metal frame are exposed on the outer surface of the panel. From the inner surface, there are still horizontal and vertical metal components. There has never been a design form of a mullion-free curtain wall structure on the inside and outside of the glass panel. [0003] However, as owners and architects continue to increase their requirements for building transparency, beauty, and style, mullion-free cur...

AI Technical Summary

Problems solved by technology

At present, with this new type of mullionless glass curtain wall, the traditional method of applying sealant to the vertical joints of the two glass panels is to apply sealant on the inside and outside at the same time. glue quality

In addition, it is not possible to carry out drainage measures for possible deep rainwater and condensation water
