Seal connection method and structure of exposed frame curtain wall

Abstract

The invention relates to a seal connection method of an exposed frame curtain wall. The method comprises the following steps of: 1, arranging a ternary ethylene propylene rubber bar at a connection position of two angles of an aluminum alloy vertical post and hollow glass; 2, placing a ternary ethylene propylene rubber bar between an aluminum alloy decoration pinch plate on a vertical aluminum alloy decoration cover plate of the exposed frame curtain wall and the hollow glass; 3, respectively coating a layer of sealing glue on the surfaces of the ternary ethylene propylene rubber bars of the step 1 and the step 2; 4, placing a backer rod between the hollow glass and the aluminum alloy vertical post before installing the aluminum alloy cover plate; and 5, coating a layer of sealing glue at a bonding position among the backer rod, the hollow glass and the aluminum alloy vertical post. A seal connection structure of the exposed frame curtain wall comprises the aluminum alloy vertical post, the hollow glass, the aluminum alloy decoration cover plate, the aluminum alloy decoration pinch plate, the sealing glue, the ternary ethylene propylene rubber bar and the backer rod. Compared with the prior art, the seal connection structure has the advantages of good sealing performance, no water leakage, complete water tightness due to two times of sealing and the like.

Description

technical field [0001] The invention relates to a sealing connection method and structure, in particular to a sealing connection method and structure of an exposed frame curtain wall. Background technique [0002] At present, EPDM strips are used to apply sealant on the vertical buckle cover of the exposed frame curtain wall, such as figure 1 shown. But there are obvious disadvantages in this way of gluing: [0003] 1. Due to the thin thickness of the sealant applied on the outside of EPDM rubber, the sealing performance will decrease significantly after a long time of use, and the EPDM rubber strip does not have waterproof performance, so it is easy to appear after several years of use. Local water leakage. [0004] 2. Once water leakage occurs, no water leakage point can be detected at all, and it cannot be repaired. [0005] 3. If the building has a high floor, it is inconvenient to maintain in case of water leakage. Contents of the invention [0006] The purpose o...

Problems solved by technology

[0003] 1. Due to the thin thickness of the sealant applied on the outside of EPDM rubber, the sealing performance will decrease significantly after a long time of use, and the EPDM rubber strip does not have waterproof performance, so it is easy to appear after several years of use. Partial water leakage

[0004] 2. Once a water leak occurs, the leak point cannot be found at all, and it cannot be repaired

[0005] 3. If the building floor is high, in case of water leakage, it is inconvenient to maintain
