Embodiment 1

[0044] Embodiment 1: as figure 1 As shown, a post-cast belt waterproof structure includes a belt body 2 arranged between adjacent substrates 1, the substrate 1 is formed by pouring concrete, and a plurality of end-to-end spliced ​​protective plates 3 are placed on the upper surface of the substrate 1 to protect The plate 3 is used to cover the strip body 2 so as to prevent moisture from entering the strip body 2 .

[0045] A plurality of steel bars 11 are laid in the matrix 1 , and one end of the steel bars 11 extends into the belt body 2 , and the steel bars 11 on both sides of the belt body 2 correspond one by one. The surface of the exposed steel bar 11 is covered with a waterproof membrane 111, which is used to protect the steel bar 11 and avoid corrosion of the steel bar 11 exposed to the air for a long time; a sleeve 5 is arranged between the opposite steel bars 11, and the sleeve 5 is two-stage. The connection between the two sections of sleeves 5 is realized through s...

Embodiment 2

[0054] Embodiment 2: as figure 1 , figure 2 Shown is a post-cast waterproof structure. The difference between this embodiment and Embodiment 1 is that in this embodiment, the shell 61 is made of non-toxic AS resin. AS resin is a polymer compound formed by the copolymerization of acrylonitrile and styrene. It has excellent solvent resistance and good load bearing capacity. It is not easy to be damaged during concrete pouring, so as to avoid the shell 61 cracking and affecting the post-casting belt. pouring.

Embodiment 3

[0055] Embodiment 3: as figure 1 , figure 2 As shown, a post-cast waterproof structure, the difference between this embodiment and embodiment 1 is that in this embodiment, the shell 61 includes three layers, the outer layer is made of non-toxic AS resin, and its excellent solvent resistance The outer shell 61 can be prevented from decomposing when encountering water; the middle layer is made of ABS plastic, so as to increase the strength and toughness of the pouring pipe 6, and can effectively prevent concrete from breaking into the pouring pipe 6; the inner layer is made of non-toxic PS plastic. PS plastic refers to a class of plastics including styrene base in the macromolecular chain, including styrene and its copolymers. Specific varieties include general-purpose polystyrene (GPPS), high-impact polystyrene (HIPS), expandable Polystyrene (EPS) and metallocene polystyrene (SPS), etc. In this embodiment, general-purpose polystyrene is selected, and its melting temperature i...

Abstract

The invention discloses a post-cast tape waterproof structure and a construction method thereof, wherein the waterproof structure includes a belt body arranged between adjacent substrates, steel bars are arranged on the substrate, and a plurality of end-to-end joints are placed on the upper surface of the substrate to cover The protective plate with body, the middle part of the protective plate is bent downward to form a water collection pipe, the middle part of the protective plate forms a water inlet with a width smaller than the diameter of the water collection pipe, and the upper surface of the protective plate on both sides of the water inlet slopes downward to the water inlet, and the two sides of the water collection pipe The end is fixed with an overflow plate whose upper surface height is lower than that of the water inlet. In this scheme, a protective plate is used to cover the belt body, and a water inlet and a water collecting pipe are arranged on the protective plate. The water flows into the water collecting pipe along the surface of the protective plate. The weight of the water in the water collection pipe makes the protective plate and the surface of the substrate more tightly, so as to prevent moisture from penetrating from between the protective plate and the substrate, thereby effectively preventing water from entering the post-casting belt.

Description

technical field [0001] The invention relates to the technical field of building construction waterproofing, in particular to a post-cast tape waterproofing structure and a construction method thereof. Background technique [0002] The post-pouring belt is a temporary part set at the corresponding positions of the foundation floor, wall and beam in order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement during construction. construction joints. In the construction of high-rise buildings and basements of large shopping malls, post-pouring belt construction and basement waterproofing are two key operating procedures. However, in the specific construction process, construction personnel often only pay attention to the waterproofing of the outer wall and the floor and ignore the waterproof construction of the post-casting belt. A series of quality problems of the post-casting belt will app...
