Device used for connecting curtain wall aluminum alloy cross beam with upright

Abstract

The invention relates to a component type device used for connecting an curtain wall aluminum alloy cross beam with an aluminum alloy upright. The device mainly comprises the aluminum alloy upright, the aluminum alloy cross beam and an aluminum alloy bracket, wherein the aluminum alloy bracket is a right-angled component of which one side is inserted in the rectangular cavity of the aluminum alloy cross beam and the other side closely sticks to the limit groove of the aluminum alloy upright; one side of the the aluminum alloy bracket is the rectangular cavity which has two triangular edges on each of four sides; the head of the inserted side of the aluminum alloy bracket is a cone with a guiding function; and the other side sticking to the aluminum alloy upright is a flat rectangular hexahedron. The device of the invention has simple, compact and reasonable structure; and under the guidance of the cone with the guiding function, the aluminum alloy bracket can be conveniently inserted in the cavity of the aluminum alloy cross beam, then the aluminum alloy bracket is placed against the aluminum alloy upright and finally the cross beam is arranged on the upright by screwing up two bolts. The device is suitable for various component type curtain wall systems such as hidden frame curtain walls, semi-hidden frame curtain walls and exposed frame curtain walls.

Problems solved by technology

[0002] In the installation of component-type curtain walls, it is often necessary to install and fix the aluminum alloy beams to a certain height position of the aluminum alloy columns. The angle aluminum is connected to the aluminum alloy beam, and then two bolts are used to connect the angle aluminum and the aluminum alloy beam to the aluminum alloy column. The process is complicated, the installation accuracy is low, the efficiency is low, and human resources are wasted.

Moreover, the stress on the components is unreasonable. The bolts bear the gravity of the curtain wall itself and the triple load of the horizontal wind load and the horizontal earthquake force. Due to the limitation of the geometric size, the bolt specifications cannot be enlarged accordingly, which poses a safety hazard.

When the aluminum alloy beam is loaded by glass, the beam is prone to tilt under the action of eccentric force, which affects the appearance
