Glue injection flow deflector for two ends of assembled mullion corner brace in doors and windows

Abstract

The invention relates to a glue injection flow deflector for the two ends of an assembled mullion corner brace in doors and windows. The glue injection flow deflector is characterized by comprising a glue injection flow deflector body; the glue injection flow deflector body is rectangular, small columnar jaws are arranged on the back face of the glue injection flow deflector body, and a rectangular through groove is formed in the glue injection flow deflector body. The glue injection flow deflector has the advantages that compared with the prior art, the flow deflector is arranged on the assembled corner brace, during glue injection, the purposes that the flow direction of corner assembling glue is guided and a cavity of the corner brace is blocked to block air convection can be achieved, after the flow deflector is used, the strength and sealing performance of the corners of the doors and windows are greatly improved, and more importantly, the energy-saving effect of the windows can be improved. Through the glue injection flow guide process, the situation of leakage and dew formation at the corners is completely eradicated. According to the mullion glue injection flow deflector, hard connection of the assembled corners of the doors and windows is changed into glue flexible connection, and therefore leakage can be completely eradicated from the source.

Description

technical field [0001] The invention belongs to door and window fittings, in particular to a glue-injected guide plate at both ends of a stile in a door and window assembly. Background technique [0002] The assembly of aluminum alloy door and window mullions adopts a mechanical connection process. Generally, screw connection is used without glue injection process. Use the cut aluminum alloy corner brackets to rigidly connect the door and window stiles and corner brackets through corner rubber mechanical extrusion, so that the gaps on the sides cannot be filled, and it is easy to cause water leakage on the doors and windows. There will be gaps in the middle stile during mechanical connection. After installation, after long-term wind pressure, it is very easy to cause leakage in the middle stile of aluminum alloy doors and windows, and the leakage problem is difficult to solve. Hidden dangers such as the window sills of the newly renovated houses of the common people, the w...

Problems solved by technology

At present, there are also glues directly into the cavity of the profile, but it doesn’t work, only point-to-point bonding and gluing, the gaps are still empty, and the real sealing performance cannot be achieved.

At the same time, because there is a gap between the profile cavity and the corner bracket, it is easy to cause the deformation of the corner and the size change of the diagonal, resulting in the poor sealing of the stiles of the doors and windows, air leakage and rain leakage, which directly affect the normal use of the doors and windows

Now there is also a glue injection process without deflectors, which will greatly increase the cost, and the glue injected into the cavity of the profile will go directly into the cavity of the profile, resulting in waste of glue, and it does not play a role in the real flexible connection.
