Waterproof and leakage-proof expansion joint for roof

Abstract

The invention discloses a waterproof and leakage-proof expansion joint for a roof, and belongs to the technical field of constructional engineering. The waterproof and leakage-proof expansion joint comprises constructional joint parapet walls, an aluminum alloy panel, an aluminum alloy water guide groove and a water stop belt, the aluminum alloy panel is formed by connecting a fixed side plate, an inclined panel and an eave shielding side plate, the inner side of the aluminum alloy panel is further connected with a movable partition plate device, the water stop belts is arranged on the structural joint parapet walls in a lap joint mode, the aluminum alloy water guide groove presses the two sides of the water stop belt and is fixed to the structural joint parapet walls, the fixed side plate is fixed to the first parapet wall, the inclined face plate covers gaps between the two corresponding structural joint parapet walls, the eave shielding side plate extends out and is suspended outside the outer side wall of the second parapet wall, and meanwhile, the movable partition plate device is placed on the upper surface of the second parapet wall, so that the waterproof and leakage-proof expansion joint for the roof is formed. The waterproof and leakage-proof expansion joint for the roof has the beneficial effects that a three-stage waterproof structure and an anti-deformation structure are adopted, deposition and leakage can be avoided, and a structural body is allowed to deform along with the deformation of the expansion joint.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to an anti-leakage expansion joint of an outer wall. Background technique [0002] Due to changes in climate and temperature, building components will expand with heat and contract with cold. In construction engineering, in order to prevent cracks or damage to the building structure, a structural joint is generally arranged at an appropriate position along the construction joint direction of the building or structure. The expansion joint is to divide the building components above the foundation such as walls, floors, roofs, etc. into two independent parts, so that the building or structure can be horizontally expanded along the long direction. [0003] In construction engineering, the leakage of outdoor expansion joints has become a common problem of building leakage, and once leakage is difficult to deal with, so leakage prevention measures should be taken in cons...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an anti-deformation expansion joint structure to achieve expansion and dislocation in all directions and waterproof and leak-proof in view of the phenomenon that the roof expansion joints cannot adapt to the misalignment caused by expansion and contraction and are prone to rainwater leakage the goal of
