[0002] With the rapid development of infrastructure construction, various processes and methods in building construction are constantly being updated and improved, but there are still some long-standing unresolved problems in the construction of pre-buried drainage pipes. At present, most conventional pre-buried drainage pipes are fixed with steel bars, that is, when the construction of the floor slab steel bars is completed, the position of the drainage pipe is determined by measurement, and then the embedded parts are placed in the corresponding place, and then short steel bars are used to clamp the embedded parts around and bind them to the floor slab steel bars to fix them, and the pipe mouth is sealed with tape. However, this process will cause the embedded parts to have a certain displacement when the concrete vibrator vibrates, and the concrete slurry will also enter the embedded parts with the displacement; secondly, when the process is cross-operated, the pipe mouth tape is easily damaged, resulting in a large amount of concrete entering the embedded parts, and finally blocking the embedded parts.

[0005] Furthermore, a waterproof sleeve is provided on the outside of the embedded pipe, and the bottom end of the waterproof sleeve is in contact with the bottom mold.

[0006] Furthermore, a skirt ring is provided in the middle of the waterproof cover.

[0007] Furthermore, the waterproof cover is made of polyvinyl chloride material.

[0008] Furthermore, a positioning mold matched with the inner hole of the embedded pipe is installed on one end surface of the cover plate.

[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0019] Example 1

[0020] The following is further described in conjunction with specific embodiments. Figure 1-Figure 2 As shown, this embodiment is a reusable fixing device for embedded parts of drainage pipes for building construction, which is characterized by: comprising a bottom mold 3, an embedded pipe 2 and a cover plate 1 arranged vertically in sequence, the bottom end of the embedded pipe 2 abuts and fits with the bottom mold 3, and the cover plate 1 is sealed on the top of the embedded pipe 2; a connecting screw 4 passes through the bottom mold 3, the embedded pipe 2 and the cover plate 1, and fastening nuts 5 are provided at both ends of the connecting screw 4; specifically, after the construction of the bottom mold 3 of the floor slab is completed, a hole is drilled on the bottom mold 3 so that the connecting screw 4 passes through the hole of the bottom mold 3, and the embedded pipe 2 is placed, the top of the connecting screw 4 passes through the cover plate 1, and the cover plate 1 is covered on the top of the embedded pipe 2, the fastening nuts 5 at both ends of the connecting screw 4 are tightened and locked, and the exposed connecting screw 4 and fastening nut 5 are wrapped with tape to prevent adhesion when pouring concrete 9, so that the concrete 9 solidifies on the connecting screw 4 and is difficult to remove. Then, after the two ends of the embedded pipe 2 are closed, concrete 9 can be poured on the bottom mold 3. During this process, the fixing device is not prone to deviation and concrete 9 entering the embedded pipe 2. When the concrete 9 is solidified, the cover plate 1, the connecting screw 4 and the fastening nut 5 are removed for secondary use, and the construction efficiency is high.

[0021] In addition, a waterproof sleeve 6 is provided on the outside of the embedded pipe 2. The length of the waterproof sleeve 6 is approximately half of the embedded pipe 2, and the diameter of the waterproof sleeve 6 is adapted to the embedded pipe 2. The bottom end of the waterproof sleeve 6 is abutted against the bottom mold 3. The waterproof sleeve 6 can isolate the concrete 9 and the embedded pipe 2. The embedded pipe 2 can still be removed even after the concrete 9 solidifies.

[0022] In order to increase the bearing surface, a skirt ring 7 is provided in the middle of the waterproof sleeve 6, so that the waterproof sleeve 6 and the embedded pipe 2 are not easy to fall over during the pouring of the concrete 9.

[0023] It is worth noting that the waterproof cover 6 in this embodiment is made of polyvinyl chloride material, which has excellent waterproof performance and is not easily corroded by acid, alkali, salt and other solutions.

[0024] In order to prevent the embedded pipe 2 from lateral displacement relative to the connecting screw 4 during the pouring of concrete 9, a positioning mold 8 matched with the inner hole of the embedded pipe 2 is installed on one side end face of the cover plate 1. The edge of the positioning mold 8 presses against the inner wall of the embedded pipe 2. When the embedded pipe 2 is subjected to lateral force, the force is transmitted to the connecting screw 4 through the positioning mold 8. Since the connecting screw 4 and the fastening nut 5 are fixed, the entire fixing device will not be displaced.

[0025] It can be explained that, in order to facilitate assembly and disassembly, or to replace the positioning mold 8 according to the diameter of the embedded pipe 2, the positioning mold 8 and the cover plate 1 are detachably connected by screws.

[0026] The cover plate 1 in this embodiment is a square plate or a circular plate. The area of ​​the cover plate 1 is larger than the diameter of the embedded pipe 2. The cover plate 1 can be made of waste wood materials at the construction site to save costs.

[0027] Example 2

[0028] Different from Example 1, Figure 2 As shown, the fixing device can also be used for pre-buried installation of the floor drain 10.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
