Rainwater leakage prevention structure for precast concrete external wall panel

Abstract

The invention provides a rainwater leakage prevention structure for a precast concrete external wall panel. The precast concrete external wall panel is composed of precast concrete slabs and structural components, wherein a horizontal gap separating belt is formed at the intersection position of the upper and lower adjacent precast concrete slabs, a vertical gap separating belt is formed at the intersection position of the left and right adjacent precast concrete slabs, horizontal connecting pieces used for connecting the upper and lower adjacent prefabricated concrete slabs are arranged at the horizontal gap separating belt position, the horizontal connecting pieces comprise a water separation component I and a water conveying component I which are perpendicular to each other, and vertical connecting pieces used for connecting the left and right adjacent prefabricated concrete slabs are arranged at the vertical gap separating belt position, and each vertical connecting piece comprises a water separation component II and a water conveying component II which are perpendicular to each other. According to the rainwater leakage prevention structure, the upper and lower adjacent prefabricated concrete slabs are connected through the horizontal connecting pieces, the left and right adjacent prefabricated concrete slabs are connected through the vertical connecting pieces, the structure is simple, and assembling and using are convenient.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a rainwater seepage-proof structure for prefabricated concrete exterior wall panels. Background technique [0002] The public number is CN101864829B, which provides a prefabricated concrete exterior wall slab anti-rainwater leakage structure. The intersection of every two left and right adjacent precast concrete slabs forms a vertical separation joint; every two upper and lower adjacent precast concrete slabs are stepped. The connections form the horizontal separation joints on the outside of the building, the internal separation joints and the horizontal separation joints on the inside of the building; the foamed polyethylene round rods and waterproof glue are set on the horizontal separation joints on the inside of the building and on the vertical separation joints on the inside of the building; The horizontal partition on the outside of the building forms a wedg...
