Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for attaching a mullion and a mullion to a building frame, and then using an edge frame to fit the glass into the glass fitting groove between the mullion and the mullion. relates to a method for on-site installation of glass in curtain walls.

[Conventional technology]

A typical example of this type of attachment method is the method disclosed in Japanese Unexamined Patent Application Publication No. 60-212547, which is generally known. According to this method, mullions and mullions are attached to the main body side in the same way as with general curtain walls, and a framework is constructed in which the glass will be placed. Glue it to the back side of the glass, top, bottom, left and right edges, with the inside facing up, and prepare for installation. Normally, a glass fitting groove is formed in the mullion and the open space, but in this installation method, the frame is especially used for installation, so the support surface of the outdoor wall is It is no longer needed, so the outdoor side of the glass fitting groove is left open. After the glass is suspended from this open surface and once placed in the glass fitting groove, the legs of the clip are inserted into the opening of the frame, and the clip is further pulled to the side of the room using bolts for installation. At the same time, airtightness is achieved by pressing the edge frame against the mullions and tight material pre-attached to the mullions.

After construction, there is nothing to support the glass in front of the glass, and the joint width is relatively narrow, improving the overall appearance of the building. In this way, the exterior appearance is quite innovative compared to ordinary curtain walls, and many constructions are expected in the future.

[Problem that the invention seeks to solve]

In the conventional method, before the glass is erected, a frame must be attached to the back side of the glass and the top, bottom, left and right edges, and in many cases this also needs to be done at a factory, etc., off-site. Many of these factories are far away from the site, and considering the current traffic conditions, it takes a lot of time and money to transport them.

Therefore, there is a need for a method of installing glass that can be installed on site without having to transport each glass to a factory, etc., and that can be easily replaced.
