Problems solved by technology
At present, PVC pipes or ordinary steel sleeves are mostly used for pre-embedding, and they are taken out after the concrete is formed. However, PVC pipes or ordinary steel sleeves are often closely bonded to concrete and are not easy to take out. They are directly discarded after use, resulting in waste of materials; and construction Inconvenient, poor forming of the tube hole
Once it cannot be removed, it is often necessary to destroy the embedded casing, and it is also easy to cause damage to the reserved holes, affecting the quality of the structural layer

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the embedded casing used in the present invention and the accompanying drawings.
[0027] During specific implementation: if figure 1 , figure 2 and image 3 As shown, a new type of reusable pre-embedded casing includes a straight tube body as a whole, the tube body includes a first bending part 1, a second bending part 2 and a connecting part 3, the first bending part A bending part 1, the second bending part 2 and the cross section perpendicular to the length direction of the connecting part 3 are all in the shape of a minor arc; One side of the direction is hinged through the hinge shaft, and the other side is hinged with the inferior arc circumferential side of the second bending part 2 through the hinge shaft; the first bending part 1 and the second bending part 2 are both The tubular body can be rotated about the axis of the tubular body around their respective hinges; the mova...

The invention discloses a floor slab waterproof sleeve casting construction method, which is characterized by comprising the following steps that: an embedded sleeve in the following structure is obtained, wherein the embedded sleeve comprises a pipe body integrally in a straight pipe shape; the pipe body comprises a first bending part, a second bending part and a connecting part; each of the cross sections, perpendicular to the length direction, of the first bending part, the second bending part and the connecting part is in an inferior arc shape; one side in the circumferential direction of the inferior arc of the connecting part is hinged to one side in the circumferential direction of the inferior arc of the first bending part through a hinge shaft; the other side in the circumferential direction of the inferior arc of the connecting part is hinged to one side in the circumferential direction of the inferior arc of the second bending part through a hinge shaft; the first bending part and the second bending part can rotate around the respective hinge shaft towards the axis direction of the pipe body; and the movable side of the first bending part and the movable side of the second bending part can be butted to form a round pipe body. The floor slab waterproof sleeve casting construction method has the advantages that the operation is simple and convenient; the construction cost can be reduced; the construction quality is high, and the like.
Description
technical field [0001] The invention relates to the technical field of high-rise building construction, in particular to a floor waterproof casing pouring construction method. Background technique [0002] Waterproof casing is also called wall casing, wall pipe. The flexible waterproof casing is generally suitable for structures where the pipe passes through the wall and is subject to vibration or strict waterproof requirements. After the casing part is processed, the outer wall is painted with a primer (the primer includes camphordan or cold primer oil) . Waterproof casings are divided into rigid waterproof casings and flexible waterproof casings. The two are mainly used in different places. The flexible waterproof casing is mainly used in places with high requirements such as civil defense walls and pools, and the rigid waterproof casing is generally used in places where pipelines need to pass through pipelines such as basements. [0003] The waterproof casing is often ...
