Novel sealing strip for building

Abstract

The invention relates to a novel sealing strip for a building. The 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). 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 arranged at the inner side of the second inclined section (3). Outer teeth (7) are arranged at the outer side of the third inclined section (4). A pectinate insertion body (10) made of resin is embedded into the sealing strip. The insertion body (10) comprises a main body (10.1) and tooth portions (10.2). The novel sealing strip for the building is small in consumption, good in sealing effect, convenient to mount, low in cost and applicable to doors and windows with complex profile cross sections; and meanwhile, large gripping force is achieved between the sealing part and a matched part, and in the bending operation process, good flexibility is achieved.

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 helpless; 5) Now Some sealing strips are made of pure rubber material, so the grip on the fittings is small, and the flexibility is poor during the bending operation, which cannot meet the needs of customers
