Novel building sealing strip

Abstract

The invention relates to a novel building sealing strip. The novel building sealing strip comprises a transverse section (1), a first inclined section (2), a second inclined section (3), a third inclined section (4), a fourth inclined section (5) and a fifth inclined section (6), wherein the first inclined section (2), the second inclined section (3), the third inclined section (4), the fourth inclined section (5) and the fifth inclined section (6) are connected end to end to form a hollow structure (9), the left end of the first inclined section (2) and the left end of the fourth inclined section (5) are both connected with the right end of the transverse section (1), inner teeth (8) are formed in the inner side of the second inclined section (3), and outer teeth (7) are formed in the outer side of the third inclined section (4). The novel building sealing strip is good in sealing effect, convenient to mount and also low in cost, and is suitable for doors and windows with complex cross-sections of profiles, and the use amount of the sealing strip is low.

Description

technical field [0001] The invention relates to a sealing strip, which is suitable for doors and windows with complex profile sections. The utility model belongs to the technical field of accessories for building doors, windows and curtain walls. Background technique [0002] During the use of building doors, windows and curtain walls after installation, the corners are the main parts of the doors, windows and curtain walls for water and air leakage. The treatment methods at the corners and corners are as follows: 1) The cut-off sealing strips are only physically lapped. Any other treatment; 2) Cold glue the sealing strip with quick-drying glue on site; 3) Install the factory-prefabricated corners. Among them, the first two are mainly used in some low-end door and window curtain walls, while the third type is often used in high-end door and window curtain walls. From the perspective of sealing, it is a better treatment method, but this method also has the following four di...

AI Technical Summary

Problems solved by technology

From the perspective of sealing, it is a better treatment method, but this method also has the following four disadvantages: 1) The cost of prefabricated corners is high; 2) This only transfers the defective parts of the seal to not far from the corners, and prefabricated corners The physical connection with the sealing strip may still be a hidden danger of water leakage and air leakage; 3) There is a joint between the prefabricated corner and the sealing head, which is not beautiful; 4) If you encounter doors and windows with complex cross-sections, this treatment method is powerless
