Description

A glass curtain wall corner expansion joint system

technical field

The utility model belongs to the field of curtain walls, in particular to a corner expansion joint system for glass curtain walls.

Background technique

Glass curtain wall refers to the outer protective structure suspended on the main body of the building with glass as the main material. It mainly inlays the glass plate with an aluminum frame around it to form a curtain wall element, and inlays the curtain wall element on the beam and column set on the main body of the building. Then form the curtain wall system form. In order to avoid the slight displacement/deformation of the main body of the building due to factors such as weather or geological movement, resulting in damage to the glass curtain wall, the expansion joints of the glass curtain wall came into being.

Conventional curtain wall expansion joints are set according to the location of the main body of the building, and usually use special structures and special materials, which is inconvenient to install. Especially for the glass curtain wall expansion joint system between the main building bodies that are perpendicular to each other, the connection reliability and good Sealing and waterproofing are particularly important. Of course, it is also necessary to ensure the aesthetics and facade effect of the expansion joint system relative to the building after installation.

Detailed ways

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, a glass curtain wall corner expansion joint system includes two right-angled and parallel veneers 1; a transition plate 2 is provided at the end of the veneer; the transition plate 2 includes a bottom plate 22 , the draw-in groove 21 that is vertically arranged at the two ends of the bottom plate, the connecting plate 23 that is arranged on the extended surface of one end of the bottom plate 22, and the right-angled sealing plate 24 that is vertically arranged at the other end of the bottom plate 22; the two veneers 1 The end is clamped in the slot 21 of the transition plate 2 through the flexible gasket 3; the veneer 1, the slot 21 and the bottom plate 22 form a circumferentially closed hollow structure, and the hollow structure is filled with a foaming agent 4.

Further, the transition plate 2 adopted in this embodiment also includes a positioning plate 25 arranged perpendicular to the connecting plate 23 .

Further, the card slot 21, the bottom plate 22, the connecting plate 23, the sealing plate 24 and the positioning plate 25 used in this embodiment are integrally formed. This design can simplify the structure of the transition plate 2 without too many unit connection relationships , It is very convenient to use and install.

Furthermore, the veneer 1, the transition plate 2 and the flexible spacer 3 used in this embodiment are all made of aluminum alloy. This design can prevent rust and corrosion while ensuring the overall structure is light.

As shown in Figure 4, for two mutually perpendicular building main bodies 5, glass curtain walls 10 are installed through aluminum alloy columns 6. The bottom of the glass curtain wall is fitted and positioned, and then the connecting plate 23 and the side of the aluminum alloy column 6 are fastened by stainless steel screws 7 to realize the reliable connection of the transition plate 2 to ensure the reliable connection of the subsequent entire glass curtain wall corner expansion joint system. Next, the ends of the two veneers 1 are clipped into the flexible gasket 3 and then inserted into the slot 21. One right-angled side of the right-angled sealing plate 24 is flush with the outside of the glass curtain wall 10, and the other right-angled side is flush with the outside of the glass curtain wall. The sealant 9 at the end of 10 is connected, combined with the veneer 1 and the flexible gasket 3, a good sealing and waterproof structure is formed inside and outside the expansion joint system. Finally, the foaming agent 4 is filled into the hollow structure surrounded by the veneer 1, the slot 21 and the bottom plate 22, so that the two veneers 1 are connected as one, and are fixed relatively tightly under the plug of the flexible gasket 3. In the card slot 21, the whole installation process is convenient and fast.

The main body 5 of the two buildings is relatively independent, and there is a gap opening 8 between them. Under the influence of factors such as weather or geological movement, the main body 5 of the building will drive the glass curtain wall 10 installed on it to make a slight displacement, such as the horizontal or vertical direction in the diagram, or even When settling, make a movement vertical to the direction shown in the figure. At this time, the veneer 1 and the foaming agent 4 in the card slot 21 overcome the friction of the flexible gasket 3 and perform corresponding telescopic movements to ensure that the aluminum alloy column and The glass curtain wall installed on it will not be damaged.

The utility model is installed at the corners of the main bodies of two vertically standing buildings, and the corresponding veneer 1 is also in a right-angle shape, which also achieves the purpose of not affecting the beauty of the building and the effect of the facade.

Finally, it is noted that the above preferred embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that it can be described in the form Various changes can be made in the above and in the details without departing from the scope defined by the claims of the present invention.
