A kind of installation method of sealing rubber strip for broken bridge aluminum alloy doors and windows

Abstract

The invention provides a method for installing a sealing rubber strip for aluminum alloy doors and windows with broken bridges. In the middle, if the rubber strip with glue is applied and then hold it, part of the glue in the hand-held part may be taken away by the hand, which reduces the surface viscosity of the rubber strip in the hand-held part, thereby reducing the connection between the notch and the rubber strip in the later stage. , and because it is artificially embedded, the rubber strip embedded in the notch may have a wavy structure, which is difficult to achieve a sealing effect, and is not aesthetically pleasing.

Description

technical field [0001] The invention relates to the field of doors and windows, in particular to a method for installing sealing rubber strips of aluminum alloy doors and windows with broken bridges. Background technique [0002] The broken bridge aluminum alloy window is an improved type introduced on the basis of the old aluminum alloy window to improve the thermal insulation performance of doors and windows. The principle of the broken bridge type aluminum alloy window is to use PA66 nylon to separate and closely connect the two layers of indoor and outdoor aluminum alloys into a whole, forming a new type of heat-insulating aluminum profile. Embedded in the sealing rubber strip, the sealing rubber strip plays an important role in waterproof, sealing and energy saving in plastic steel doors and windows, broken bridge aluminum doors and windows and wooden doors and windows. Elasticity, as well as good temperature resistance and aging resistance. [0003] In the process of...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a method for installing a sealing rubber strip for aluminum alloy doors and windows on broken bridges, which can solve the problem of partial glue on the hand-held part when the rubber strip coated with glue is held in the hand during the traditional installation process. It is taken away by the hand, which reduces the surface viscosity of the rubber strip on the hand-held part, thereby reducing the connection between the notch and the rubber strip in the later stage, and because it is artificially embedded, the rubber strip embedded in the notch may have a wavy structure, which is relatively It is difficult to achieve the effect of sealing, and it is not beautiful
