An external dry-hanging stone curtain wall fixing device

Abstract

The invention discloses an external dry hanging stone curtain wall fixing device. The fixing device comprises an embedded part, a steel bracket, a square steel pipe, angle steel, an aluminum alloy pendant set and a stone material, wherein the steel bracket is connected with the embedded part by welding; the square steel pipe is connected with the steel bracket through a bolt; the angle steel is continuously arranged according to a stone cutting line and welded with the square steel pipe; the aluminum alloy pendant set comprises an aluminum alloy hanging seat, an aluminum alloy hanging groove, an upper aluminum alloy pendant and a lower aluminum alloy pendant; the aluminum alloy hanging seat is L-shaped; one edge of the L shape is connected with the angle steel by a bolt while the other edge of the L shape is connected with the aluminum alloy hanging groove; one side of the upper aluminum alloy pendant and one side of the lower aluminum alloy pendant are both hung on the aluminum alloy hanging groove while the other side of the upper aluminum alloy pendant and the other side of the lower aluminum alloy pendant are hitched in a stone groove and are caulked and sealed by using epoxy resin glue; and a gap of the stone material is sealed and lined with a foam cushion rod. According to the fixing device, the stone material is connected with the square steel pipe by adopting the aluminum alloy pendant set, so that the whole stone curtain wall is in an elastic state and the wind resistance, seismic resistance and the like of the stone curtain wall are improved.

Description

technical field [0001] The invention relates to the field of curtain wall construction, in particular to an external dry-hanging stone curtain wall fixing device, which is especially suitable for buildings with high requirements for earthquake resistance. Background technique [0002] With the continuous development of stone curtain wall technology in my country, the height of buildings has generally increased, and the stone dry hanging method has become the most widely used method for stone curtain walls. In this method, the stone is directly hung on the wall by the pendant, without grouting and pasting. At present, there are many types of dry hangings on the market, but the models and installation methods of the dry hangings cannot improve the impact of external forces such as wind resistance or earthquake resistance of stone curtain walls. [0003] The public document whose application number is 200810029325.7 discloses a dry-hanging structure of a stone curtain wall. Th...

Problems solved by technology

At present, there are many types of dry hanging parts on the market, and the type and installation method of the dry hanging parts cannot improve the impact of external forces such as wind resistance or earthquake resistance of the stone curtain wall.

[0003] The public document whose application number is 200810029325.7 discloses a dry-hanging structure of a stone curtain wall. The joint between the hanging piece and the hanging seat is provided with a screw for adjusting the height deviation of the plate, and the stone plate can be replaced separately. The force point is too concentrated and easy to deform; the patent document with application number 201420812358.X discloses a stone dry-hanging node, adding adjusting gaskets and adjusting screws to make the structure safe and firm, and easy to replace, but the stone board can only enter and exit through the hanging seat The adjustment with the angle steel is relatively simple. The angle steel is connected by bolts, which weakens the overall stress of the angle steel; the patent document with the application number 201220012707.0 discloses a stone pendant and a stone curtain wall. Elastic elastic strips are set in the pendant groove without using glue Stone can be installed, but the three-dimensional adjustability of this scheme is poor
