Prefabricated external wall panel waterproof assembly structure and assembly process thereof

Abstract

The invention relates to a prefabricated external wall panel waterproof assembly structure and an assembly process thereof. The prefabricated external wall panel waterproof assembly structure comprises prefabricated wall panels and water retaining pieces arranged between the adjacent prefabricated wall panels on the same horizontal plane, and vertically-arranged water retaining grooves are formedin the side walls, close to the adjacent prefabricated wall panels, of the prefabricated wall panels; the water retaining grooves penetrate through the upper end faces and the lower end faces of the prefabricated wall panels, and the water retaining pieces are inserted into the water retaining grooves of the adjacent prefabricated wall panels at the same time. Water flowing into gaps between the prefabricated wall panels which are horizontally arranged is guided through the water retaining pieces, so that the water flows downwards, and the waterproof effect is improved.

Description

technical field [0001] The present application relates to the technical field of prefabricated wall panels, in particular to a waterproof assembly structure of prefabricated exterior wall panels and an assembly process thereof. Background technique [0002] At present, in the prefabricated construction industry, the exterior wall panels are manufactured in a prefabricated manner, and then assembled on site, so that standardization can be achieved, and the quality is controllable, efficient and fast. [0003] However, during the on-site assembly of prefabricated exterior wall panels, waterproof treatment should be carried out at the joints to prevent rainwater from seeping into the room along the joints of the exterior wall panels. The effective bearing capacity of the external wall decreased, which brought major engineering hidden dangers. [0004] The traditional waterproofing of external wall panels is usually to set a groove with a low outside and high inside for waterpr...

Problems solved by technology

[0003] However, during the on-site assembly of prefabricated exterior wall panels, waterproof treatment should be carried out at the joints to prevent rainwater from seeping into the room along the joints of the exterior wall panels. The effective bearing capacity of the external wall is reduced, which brings major engineering hidden dangers

[0004] The traditional waterproofing of external wall panels is usually to set a groove with a low outside and high inside for waterproofing under the external wall panels, but the contact between adjacent external wall panels on the same level cannot be well achieved by using the tongue and groove design. waterproof effect
