A steel-plastic composite corner bracket for aluminum alloy doors and windows

Abstract

The invention discloses a steel-plastic composition corner brace for an aluminum alloy door / window. The steel-plastic composition corner brace comprises an outer layer plastic main body and an interior metal framework, wherein the outer layer plastic main body coats the interior metal framework, multiple reinforcing locating holes are formed in the interior metal framework, framework grooves are formed in the outer side of the interior metal framework, framework protruded blocks are arranged on the inner side of the interior metal framework, the framework grooves are located in outer side grooves of the outer layer plastic main body, and the framework protruded blocks are located at inner side protruded blocks of the outer layer plastic main body. Compared with the prior art, the steel-plastic composition corner brace for the aluminum alloy door / window has the advantages that an improved interior metal framework is mainly utilized, so that the framework grooves of the interior metal framework can directly contact with aluminum alloy, and meanwhile, the framework protruded blocks can bear the pressure of an aluminum alloy frame on the inner side, so that the grooves and the protruded blocks on the two sides are matched to further reinforce the aluminum alloy door / window, and the aluminum alloy door / window is firmer and prevents from cracking and removing; and the service life is prolonged, the maintenance rate is reduced, and popularization and application values are achieved.

Description

technical field [0001] The invention relates to an aluminum alloy door and window fitting, in particular to a steel-plastic composite corner bracket for an aluminum alloy door and window. Background technique [0002] In architecture, corner brackets are hardware that connect components that intersect at 90 degrees at right angles. The model and form of the corner code and the type of material are determined according to the force of the connected components. Corner codes are often used in decoration engineering and furniture assembly. For example, curtain wall installation is connected by corner codes. In the frame assembly of aluminum alloy doors and windows, the corners are put into the end of the frame, and the hydraulic press is used to squeeze the interior of the aluminum alloy to fit the corners, so as to achieve the effect of forming, but the existing technology Most of the corners are made of plastic, and the internal skeleton is a straight strip, while the alumi...

Problems solved by technology

In the frame assembly of aluminum alloy doors and windows, the corners are put into the end of the frame, and the hydraulic press is used to squeeze the interior of the aluminum alloy to fit the corners, so as to achieve the effect of forming, but the existing technology Most of the corners are made of plastic, and the internal skeleton is straight, but the aluminum alloy profiles of doors and windows cannot be completely strained, which will lead to cracking or even falling off of the seams after a little longer use time. Therefore, there is room for improvement
