Exposed frame glass curtain wall

Technical Field

The application relates to the technical field of curtain walls, in particular to a glass curtain wall with an exposed frame.

Background

The glass curtain wall is a building envelope structure or a decorative structure which has a certain displacement capacity relative to the main structure and does not bear the action of the main structure. The glass curtain wall has good visual effect by using aluminum alloy keels and glass surface layers.

The exposed frame glass curtain wall has the double functions of a framework structure and glass fixing due to the aluminum alloy section, and is wide in application. In order to improve the decorative effect of the glass curtain wall, the LED lamp strip can be installed on the glass curtain wall, and the lamp strip is generally installed on a buckle plate of an aluminum alloy framework.

With respect to the related art in the above, the inventors consider that: when the buckle need carry out the bearing to the lamp area of great region, including the weight of buckle self, the connection stability of buckle reduces, and punches on the buckle and increase the steadiness in order to use bolted connection and arouse the seepage again easily.

Disclosure of Invention

The application provides a bright frame glass curtain wall adopts following technical scheme:

a exposed frame glass curtain wall comprises a vertical column and a cross beam, wherein the vertical column is vertically fixed on a building wall body, the cross beam is horizontally fixed on the vertical column, a boss for supporting a glass unit is respectively and integrally fixed on the vertical column and the cross beam, a pressing plate for pressing the outer edge of the glass unit is fixed on the boss through a bolt, a fastening strip is fastened on one side, away from the glass unit, of the pressing plate, a through hole for the bolt to pass through is formed in the middle of the pressing plate, fastening hooks are integrally arranged on the edges of the two sides, two fastening hooks are arranged on each side, a groove for installing a sealing strip is; the lines are of a section with an open surface, and clamping edges matched and clamped with the clamping grooves are fixedly arranged on two adjacent side walls of the open end of the lines.

Through adopting above-mentioned technical scheme, the clamp plate installation back moves the lines to the clamp plate, and the card arris can block admittedly to the draw-in groove of clamp plate side edge for the layering is direct to block admittedly to the clamp plate on. The sealing strip can be installed in the groove of the pressing plate, and the waterproof performance between the pressing plate and the glass unit is further improved. Because the clamping edges are matched with the clamping grooves to be clamped and fixed, the path that external rainwater flows around to enter the interior of the lines is increased to a certain extent, the possibility of leakage is reduced, and the integral anti-seepage effect of the glass curtain wall is improved.

Optionally, the pressing plate is integrally provided with a limiting hook which is far away from the clamping hook and is parallel to the axis of the through hole, two adjacent side walls of the opening end of the line are fixedly provided with limiting strips, and when the clamping edges are clamped and fixed in the clamping grooves, the limiting hooks are abutted with the limiting strips to limit the line to move towards the pressing plate.

Through adopting above-mentioned technical scheme, after the card arris card was gone into the draw-in groove, spacing and spacing hook cooperation can stop the lines and continue to remove to the glass unit, prevent that the card arris from being close to the draw-in groove of the one side sliding out of pothook along the draw-in groove. And spacing hook is equivalent to block in between card arris and the spacing strip, still plays the solid effect of secondary card, has further improved the installation steadiness between lines and the clamp plate.
