Description

Widened combined sealing strip and window frame using same

Technical Field

The utility model relates to the technical field of doors and windows, in particular to a widened combined sealing strip and a window frame using the same.

Background

The bridge-cut-off aluminum is also called heat-insulating bridge-cut-off aluminum profile, heat-insulating aluminum alloy profile, bridge-cut-off aluminum alloy, cold and hot bridge-cut-off profile, bridge-cut-off aluminum plastic composite profile. It has more excellent performance than common aluminum alloy section. Specifically, because aluminum alloy is metal and has relatively fast heat conduction, when the indoor and outdoor temperatures are different greatly, the aluminum alloy can become a bridge for transferring heat, and the heat insulation performance of the door and window made of the material is poor. The bridge-cut aluminum is characterized in that aluminum alloy is cut off from the middle, the cut aluminum alloy is connected into a whole by hard plastic, and the plastic is known to have obviously slower heat conduction than metal, so that heat cannot easily pass through the whole material, the heat insulation performance of the material is improved, and the name of the bridge-cut aluminum (alloy) is the origin.

The bridge-cut aluminum has the characteristics of reducing heat conduction, preventing condensation, saving energy, protecting environment, reducing noise and the like. The production method of the heat insulation section mainly comprises two production modes, one mode is that a heat insulation strip material and an aluminum section are adopted, and a heat insulation bridge is formed through the processes of mechanical tooth punching, strip penetrating, rolling and the like, and is called as a heat insulation section 'strip penetrating type'. The other method is to pour the heat insulation material into the heat insulation cavity of the aluminum alloy section bar, and form a heat insulation bridge through the working procedures of curing, removing bridge-cut metal and the like, which is called as a pouring type heat insulation section bar.

The bridge cut-off aluminium door and window among the correlation technique includes window frame and casement, is provided with the duckbilled strip of paper used for sealing up on the bottom surface of window frame, and when window frame and casement closed connection, the duckbilled strip of paper used for sealing up plays the effect in the gap between sealed window frame and the casement.

However, in the existing bridge-cut-off aluminum door and window, the sealing strip made of single material is adopted to seal the gap between the window frame and the window sash, the effect is poor, and the service life is short.
