Description

Technical Field

[0001] The invention relates to the field of pipeline positioning support, and in particular to a protective positioning device for hot-melt parts of pre-buried water supply pipes. Background Art

[0002] In cast-in-place concrete shear wall structures, pre-buried water pipes are an important part of the building's water supply and drainage system. The traditional construction process is usually divided into two stages: first, the reinforcement workers complete the binding of the shear wall reinforcement, and then the plumbers install and hot-melt the water pipes; However, the above construction method has certain technical defects, especially in the protection of the hot-melt connection parts. Since the strength of the connection area formed by the hot-melt connector during the hot-melt process is relatively low, during the concrete pouring and vibration process, the mechanical action of the vibrating device can easily cause the water supply pipe to be stressed, thereby producing a tendency to break and separate. Therefore, it is very easy to cause cracking or damage to the hot-melt parts. This damage is difficult to be found after the concrete hardens, but it may cause leakage problems when water is passed through in the later stage. Since the water pipe is completely embedded in the shear wall, once leakage occurs, the maintenance work will be extremely complicated, not only requiring the destruction of the wall structure, but also possibly affecting the integrity and safety of the building.

[0003] Therefore, how to effectively protect the hot-melt connection parts of the pre-buried water supply pipes and avoid damage during the concrete vibration process has become an important technical problem in the construction of cast-in-place concrete shear walls. In order to solve this problem, it is urgent to develop a protective positioning device specifically for the hot-melt connection parts of the pre-buried water supply pipes to ensure that the hot-melt connection parts are protected from damage during the construction process, thereby improving the construction quality and reducing the subsequent maintenance costs.

The auxiliary clamping assembly also includes a fixed The second clamping plate 8 is close to the connecting column 13 on one side of the first clamping plate 7, and the connecting column 13 is evenly arranged. The inner side of the first clamping plate 7 is provided with a first accommodating groove 16, and the inner side of the first accommodating groove 16 is provided with a first abutting block 12 along the radial movement of the water supply pipe body 1. The first abutting block 12 is arc-shaped, and one side thereof is flush with the inner wall of the first clamping plate 7.

[0022] like Figure 3-Figure 12As shown, in order to improve the firmness of the second clamping plate 8 and the water supply pipe body 1, a gluing assembly is arranged on the second clamping plate 8, and the gluing assembly includes a glue storage cavity 28 arranged on the side of the second clamping plate 8 close to the hot melt portion 6 and used to store glue, and a sealing plate 29 is arranged on the side of the glue storage cavity 28 close to the hot melt portion 6, and a through hole 30 corresponding to the glue storage cavity 28 is arranged on the inner side of the second clamping plate 8, and a push rod 20 is movably connected to the inner side of the through hole 30 along the radial direction of the water supply pipe body 1. Initially, one end of the push rod 20 protrudes from the inner wall of the second clamping plate 8, and the storage The inner side of the glue cavity 28 is movably connected with an extrusion plate 24 for extruding glue and connected to one end of the push rod 20 on one side. The sealing plate 29 is provided with a discharge hole 25 corresponding to the extrusion plate 24, and a sealing film is provided in the discharge hole 25. The second holding plate 8 is provided with a solidification shell 9 corresponding to the sealing plate 29 on the side close to the hot melt portion 6. The side of the solidification shell 9 close to the sealing plate 29 and the side facing the water supply pipe body 1 are both open, and the inner side of the end of the solidification shell 9 away from the second holding plate 8 is tightly fitted with the outer wall of the water supply pipe body 1, and is located in the glue storage cavity 28. The glue in the glue storage cavity 28 is a two-component epoxy resin glue. The partitions 23 are evenly arranged in the glue storage cavity 28. A cavity for storing the two-component epoxy resin glue is formed between adjacent partitions 23. The two components of the two-component epoxy resin glue are arranged in the cavity at intervals. There are multiple extrusion plates 24 and they correspond to the cavities one by one. The two components of the two-component epoxy resin glue are epoxy resin and curing agent. In order to mix the two components, a mixing component is arranged in the solidification shell 9. The mixing component includes a mixing mesh plate 19 slidably arranged on the inner side of the solidification shell 9. The mixing mesh The plate 19 has at least two layers, and the positions and apertures of the holes on the multi-layer hybrid mesh plate 19 are different. The side wall of the hybrid mesh plate 19 is connected with a flexible traction wire 15, and the traction wire 15 extends to the outside of the sheath 2 at one end away from the hybrid mesh plate 19. The traction wire 15 is movably connected to the sheath 2. A pull ring 10 for pulling the traction wire 15 and the hybrid mesh plate 19 as a whole is provided on the end of the traction wire 15 extending to the outside of the sheath 2. The traction wire 15 is preferably made of stainless steel wire or nylon wire, and has the advantages of high strength, smooth surface and low cost.

[0023] In addition, if Figure 1-Figure 2 , Fig.13As shown, in order to limit the water supply pipe body 1, a limiting assembly is arranged on the outer side of the sheath 2 or the water supply pipe body 1, and the limiting assembly includes a first clamp 3 arranged on the outside of the water supply pipe body 1 or the sheath 2, and the first clamp 3 is locked by bolts. A telescopic rod 5 is movably arranged on the side wall of the first clamp 3. Specifically, the movable connection is preferably a universal ball movable connection, and a ball is movably connected to the side of the first clamp 3, so that the telescopic rod 5 can be adjusted in multiple directions. The telescopic rod 5 includes an inner rod and an outer rod, which are movably connected, and the connection is tightened by a top screw. A second clamp 4 is rotatably arranged on one end of the telescopic rod 5 away from the first clamp 3, and the second clamp 4 is used to be fixed to the steel keel in the shear wall, and the second clamp 4 is locked by bolts. The telescopic adjustment of the telescopic rod 5 can make the second clamp 4 adapt to steel bars at different distances, and the second clamp 4 is rotatably connected to one end of the telescopic rod 5, which further increases the adaptability.

[0024] Working principle: when in use, after the water supply pipe body 1 is hot-melted, the sheath 2 is placed outside the hot-melt portion 6, so that the two ends of the sheath 2 correspond to the water supply pipe body 1 on both sides of the hot-melt portion 6, and then the two sheaths 2 are combined, and one end of the two sheaths 2 is gradually locked by bolts. The first clamping plate 7, the second clamping plate 8, and the solidification shell 9 are tightly fitted to the outer wall of the water supply pipe body 1, and because the push rod 20 initially protrudes from the inner wall of the second clamping plate 8, the push rod 20 is compressed when the sheath 2 is locked, and the push rod 20 pushes the extrusion plate 24 to move, and the extrusion plate 24 pushes the glue in the glue storage cavity 28 to squeeze the sealing film in the discharge hole 25, the sealing film is broken, and the glue flows into the inner cavity of the solidification shell 9. The two components of the two-component epoxy resin glue are epoxy resin and curing agent, respectively. Although they are arranged at intervals, they are not completely mixed after entering the solidification shell 9, which affects the solidification and bonding effect. Therefore, after the sheath 2 is completely tightened, the pull ring 10 can be pulled from the outside of the sheath 2, and the pull ring 10 drives the mixed mesh through the traction wire 15 The plate 19 is displaced on the inner side of the solidifying shell 9. When the multi-layer mixed mesh plate 19 is displaced, the glue is separated by the holes on the mixed mesh plate 19. When flowing through the other side of the mixed mesh plate 19, the glue will be divided into fine liquid flows and recombined after passing through the holes, thereby promoting uniform mixing and facilitating the rapid solidification of the glue. According to the amount of glue or actual conditions, traction wires 15 can be set on both sides of the mixed mesh plate 19, and the mixed mesh plate 19 can be pulled back and forth for full mixing. A single traction wire 15 can also be set. After the two components are mixed, they can be solidified, so that the second clamping plate 8 and the solidifying shell 9 are bonded to the outside of the water supply pipe body 1, thereby increasing the firmness between the second clamping plate 8 and the water supply pipe body 1. Finally, the first clamping hoop 3 is set at a suitable position on the outside of the water supply pipe body 1 or the sheath 2, so that the second clamping hoop 4 corresponds to the steel keel in the shear wall, and then the second clamping hoop 4 is clamped to the steel keel by bolts, thereby realizing the positioning and fixation of the water supply pipe body 1. In addition, in order to further ensure that the water supply pipe body 1 does not separate or break, a further reinforcement effect can be achieved through a secondary clamping component. Specifically, since the water supply pipe body 1 is made of plastic, the hot melt portion 6 will experience an elastic deformation stage and a plastic deformation stage before breaking, and finally a breaking stage. Therefore, during the elastic deformation stage and the plastic deformation stage, a small displacement tendency will occur at the hot melt portion 6 of the water supply pipe body 1. This tendency will cause the second clamping plate 8 to tend to move away from the hot melt portion 6. Since one end of the second pressure block 21 abuts against the inclined surface on the inner side of the recess 11, the second pressure block 21 is pushed by the pressure of the inclined surface under the guidance of the inclined surface. 14, the second clamping block 14 will continue to apply pressure to the water supply pipe body 1 and clamp it. At the same time, the connecting column 13 is also subjected to the pressure of the second clamping plate 8. The connecting column 13 drives the first pressure block 18 to have a tendency to approach the first clamping block 12. Under the action of the inclined surface on the inner side of the recess 17 and the inclined surface on the side of the first pressure block 18, the first clamping block 12 is subjected to the pressure of the first pressure block 18, so that the first clamping block 12 continues to apply pressure to the outer wall of the water supply pipe body 1, thereby increasing the stability between the sheath 2 and the water supply pipe body 1, avoiding the breakage and separation at the hot-melt portion 6 of the water supply pipe body 1, and cooperating with the second clamp 4 and the first clamp 3, effectively limiting the displacement of the water supply pipe body 1.
