Description

Technical Field

[0001] This invention relates to the field of pre-embedded building water pipe technology, and more particularly to a pre-embedded device for water supply pipes in shear walls. Background Technology

[0002] In building construction, PPR water supply pipes in the shear wall sections of kitchens and bathrooms are not allowed to be embedded in the concrete. Therefore, the current common practice is to pre-install pipe trenches. Before the shear wall concrete is poured, extruded polystyrene boards or wooden strips are reserved in the formwork. After the concrete is formed, the extruded polystyrene boards or wooden strips are removed to form the pipe trench for installing the water supply pipes. However, this method requires chiseling and cleaning the pipe trench, cleaning up the concrete debris, and fixing the water supply pipes. After fixing, M10 cement mortar is needed to fill the gaps and repair the grout. This is not only very troublesome, but also results in a noticeable color difference between the wall surface and the shear wall concrete after grouting, which is not aesthetically pleasing.

[0003] After searching, it was found that the application with publication number CN214461488U, entitled "A Pre-set Pipe Groove for PPR Water Supply Pipes in Shear Walls," adopts an internal pipe groove method to run the water supply pipes into the shear wall, avoiding the problems caused by pre-set surface grooves. Although the application uses staged pressure testing, some pipes may inevitably have insufficient pressure during the overall pressure test, requiring the water supply pipes to be inspected and replaced. The water supply pipes running into the shear wall have high strength and poor deformation capacity, making them difficult to pull out and re-run, resulting in significant trouble for maintenance and difficulty in handling later. Further improvements can be made.

[0004] To address these shortcomings, we proposed a pre-embedded water supply pipe device for shear walls. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pre-embedded device for water supply pipes in shear walls.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pre-embedded water supply pipe device for shear walls, comprising a shear wall body, a template, and a water supply pipe body. Vertical and horizontal reinforcing bars are bound inside the shear wall body, and the water supply pipe body is fixedly bound to the outer surface of the horizontal reinforcing bars by binding wire. A pipe groove is formed on the surface of the template, and the template is fixedly connected to the shear wall body by square timber and scaffolding steel pipes. The water supply pipe body is located in the pipe groove, and a rubber strip is inserted between the water supply pipe body and the pipe groove. The shear wall body includes a reinforcing bar protective layer, which is located outside the horizontal and vertical reinforcing bars and inside the template. Clips are fixedly installed on both sides of the pipe groove on the outer surface of the template. Fasteners are used in conjunction with the water supply pipe body, and the fasteners are fixedly connected to the clips.

[0007] Preferably, the fasteners and snap-fit ​​components are arranged in multiple sets from top to bottom, and the snap-fit ​​components are distributed at equal intervals.

[0008] Preferably, the top of the water supply pipe body is bent and extends into a pipe groove, and a plug is threaded onto the top of the water supply pipe body.

[0009] Preferably, the thickness of the rubber strip is greater than the gap width between the water supply pipe body and the pipe groove, and the rubber strip is the same length as the inner perimeter of the pipe groove.

[0010] Preferably, the snap-fit ​​component includes a post, a side groove, a spring, and a snap-fit ​​block. The outer wall of the snap-fit ​​component has a side groove, and the snap-fit ​​block is slidably connected inside the side groove. One end of the snap-fit ​​block is connected to the inner wall of the side groove through a spring, and the other end of the snap-fit ​​block has an oblique opening.

[0011] Preferably, the fastener includes a pressure ring, a side plate, and a socket, and the pressure ring and the side plate are integrally connected, and the side plate has a socket on its surface.

[0012] Preferably, the socket is provided corresponding to the post, and the diameter of the socket is larger than the diameter of the post.

[0013] Preferably, the two ends of the spring are fixedly connected to the locking block and the inner wall of the side groove, respectively, and the spring is made of manganese steel.

[0014] Preferably, the distance between the bottom surface of the card block and the template is equal to the thickness of the side plate.

[0015] Preferably, the insert is fixedly connected to the outer wall of the template, and the insert is arranged perpendicular to the template.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) This invention uses a template with a pipe groove. The pipe groove is opened according to the size of the water supply pipe body. When pre-embedding the water supply pipe body, the water supply pipe body can be fixed and tied to the horizontal steel bars with tie wire. Then, the template can be fixed and installed in place with square timber and scaffolding. A space for pouring the steel reinforcement protective layer is formed between the template and the horizontal steel bars. Part of the water supply pipe body is located in the steel reinforcement protective layer, and the other part passes through the pipe groove and extends out of the pipe groove. Then, workers can use rubber strips to insert between the pipe groove and the water supply pipe body, and use fasteners and clamps to fix it. The main body of the water supply pipe can then be reinforced again. After the shear wall main body is poured and formed, the main body of the water supply pipe can be firmly embedded in the steel reinforcement protective layer of the shear wall main body, thus completing the pre-embedding of the water supply pipe main body. This invention directly pre-embeds the main body of the water supply pipe into the shear wall main body, eliminating the trouble of pressing grooves, cleaning, fixing and grouting. The forming quality is good, and it is more beautiful and neat. At the same time, the main body of the water supply pipe is located in the steel reinforcement protective layer. When the pressure test fails, it can be easily removed and replaced without damaging the structural integrity of the shear wall main body. Later replacement and maintenance are more convenient.

[0018] (2) The present invention uses a rubber strip. The thickness of the rubber strip is greater than the width of the gap between the main body of the water supply pipe and the pipe groove. When inserted, the rubber strip deforms and seals the gap between the main body of the water supply pipe and the pipe groove, avoiding grout leakage during pouring, thereby avoiding the problem of honeycomb pitting on the main body of the shear wall and further improving the molding quality.

[0019] (3) The present invention uses fasteners and snap-fit ​​components that are easy to disassemble. The fasteners include a pressure ring, a side plate and a socket. The snap-fit ​​components mainly include a snap block, a spring and a post. When installing the fasteners, the pressure ring can be placed on the outside of the water supply pipe body, the socket can be aligned with the post, the side plate can be pressed, and the post can pass through the socket. During the process of the post passing through the socket, the socket squeezes the bevel of the snap block, so that the snap block enters the side groove. The spring is compressed and deformed until the snap block passes through the socket. The spring rebounds and pushes the snap block to reset, thus locking the side plate and locking the pressure ring, completing the fixation of the snap-fit ​​component. When disassembling, the worker only needs to use his / her fingers to push the snap block back into the side groove to remove the fastener. The worker only needs to press the fastener to complete the fixation of the water supply pipe body. The installation is very convenient and simple, which significantly improves the construction efficiency and convenience. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0032] Please refer to Figure 1-8 The shear wall water supply pipe pre-embedded device includes a shear wall body 1, a template 4, and a water supply pipe body 5. Vertical steel bars 2 and horizontal steel bars 3 are tied inside the shear wall body 1, and the water supply pipe body 5 is fixedly tied to the outer surface of the horizontal steel bars 3 by tie wire 7. The template 4 has a pipe groove 9 on its surface, and the template 4 is fixedly connected to the shear wall body 1 by square timber and scaffold steel pipes. The water supply pipe body 5 is located in the pipe groove 9, and a rubber strip 10 is inserted between the water supply pipe body 5 and the pipe groove 9. The shear wall body 1 includes a steel reinforcement protective layer 12, and the steel reinforcement protective layer 12 is located outside the horizontal steel bars 3 and the vertical steel bars 2, and the steel reinforcement protective layer 12 is located inside the template 4. The outer surface of the template 4 is fixedly installed with clamping parts 11 on both sides of the pipe groove 9. The water supply pipe body 5 is used with fasteners 8, and the fasteners 8 are fixedly connected to the clamping parts 11.

[0033] In this implementation plan: the shear wall main body 1 adopts a reinforced concrete structure, the thickness of the reinforcement protective layer 12 is not less than 20mm, the vertical reinforcement 2 and the horizontal reinforcement 3 are common structures in this field, and will not be described in detail here. The fixing method of the formwork 4 is also a common structure in this field, and is not shown in detail in the figure. There are two water supply pipe bodies 5, one for hot water and one for cold water. The spacing between the pipe grooves 9 is not less than 10cm. The pipe grooves 9 are opened according to the size of the water supply pipe body 5. When pre-embedding the water supply pipe body 5, the water supply pipe body 5 can be fixed and tied to the horizontal reinforcement 3 with tie wire 7. Subsequently, the formwork 4 can be fixed and installed in place with square timber and scaffolding. The space between the formwork 4 and the horizontal reinforcement 3 forms the pouring space of the reinforcement protective layer 12. Part of the water supply pipe body 5 is located in the reinforcement protective layer 12. Another part penetrates through the pipe groove 9 and extends out of the pipe groove 9. Then, the workers can use rubber strips 10 to insert between the pipe groove 9 and the water supply pipe body 5, and use fasteners 8 and snap-fit ​​parts 11 to fix it to reinforce the water supply pipe body 5 again. After the shear wall body 1 is poured and formed, the water supply pipe body 5 can be firmly embedded in the steel reinforcement protective layer 12 of the shear wall body 1, completing the pre-embedding of the water supply pipe body 5. This invention directly pre-embeds the water supply pipe body 5 into the shear wall body 1, saving the trouble of pressing grooves, cleaning, fixing and grouting. The forming quality is good and more beautiful and neat. At the same time, the water supply pipe body 5 is located in the steel reinforcement protective layer 12. When the pressure test is unqualified, it can be easily removed and replaced without damaging the structural integrity of the shear wall body 1. Later replacement and maintenance are more convenient.

[0034] Specifically, fasteners 8 and snap-fit ​​parts 11 are arranged in multiple sets from top to bottom, and snap-fit ​​parts 11 are distributed at equal intervals.

[0035] In this implementation plan: Fastener 8 and clamp 11 serve to assist the tie wire 7 in secondary fixing of the water supply pipe body 5, so as to prevent the water supply pipe body 5 from shifting when the shear wall body 1 is poured.

[0036] Specifically, the top of the water supply pipe body 5 is bent and extends into the pipe groove 9, and a plug 6 is threaded onto the top of the water supply pipe body 5.

[0037] In this implementation plan: the plug 6 prevents concrete from contaminating the main body of the water supply pipe 5 during concrete pouring.

[0038] Specifically, the thickness of the rubber strip 10 is greater than the gap width between the main body 5 of the water supply pipe and the pipe groove 9, and the rubber strip 10 and the inner perimeter of the pipe groove 9 are the same.

[0039] In this implementation plan: when the rubber strip 10 is inserted, the rubber strip 10 deforms and seals the gap between the water supply pipe body 5 and the pipe groove 9, preventing grout leakage during pouring, thereby avoiding the honeycomb pitting problem of the shear wall body 1 and further improving the molding quality.

[0040] Specifically, the snap-fit ​​component 11 includes a post 13, a side groove 14, a spring 17, and a snap-fit ​​block 15. The outer wall of the snap-fit ​​component 11 has a side groove 14, and the snap-fit ​​block 15 is slidably connected inside the side groove 14. One end of the snap-fit ​​block 15 is connected to the inner wall of the side groove 14 through the spring 17, and the other end of the snap-fit ​​block 15 has a bevel 16.

[0041] In this embodiment: the insert post 13 is fixedly connected to the outer wall of the template 4, and the insert post 13 is arranged perpendicular to the template 4. The oblique opening 16 facilitates the generation of component force after being pressed, and facilitates the insertion of the locking block 15 into the side groove 14.

[0042] Specifically, the fastener 8 includes a pressure ring 18, a side plate 19, and a socket 20. The pressure ring 18 and the side plate 19 are integrally connected, and the socket 20 is provided on the surface of the side plate 19.

[0043] In this implementation scheme: the insertion hole 20 is opened corresponding to the insertion post 13, and the diameter of the insertion hole 20 is larger than the diameter of the insertion post 13, so as to facilitate the passage of the insertion post 13.

[0044] Specifically, the two ends of the spring 17 are fixedly connected to the inner wall of the block 15 and the side groove 14, respectively, and the spring 17 is made of manganese steel.

[0045] In this embodiment: the spring 17 connects the locking block 15 and the side groove 14 to prevent the locking block 15 from falling off.

[0046] Specifically, the distance between the bottom surface of the card block 15 and the template 4 is equal to the thickness of the side plate 19.

[0047] In this implementation scheme: After the locking block 15 is reset, it can clamp the side plate 19 to prevent the side plate 19 from falling off. When installing the fastener 8, the pressure ring 18 can be placed on the outside of the water supply pipe body 5, the insertion hole 20 is aligned with the insertion post 13, and the side plate 19 is pressed. The insertion post 13 passes through the insertion hole 20. During the process of the insertion post 13 passing through the insertion hole 20, the insertion hole 20 squeezes the inclined opening 16 of the locking block 15, so that the locking block 15 enters the side groove 14. The spring 17 is compressed and deformed until the locking block 15 passes through the insertion hole 20. The spring 17 rebounds and pushes the locking block 15 to reset, thus locking the side plate 19 and the pressure ring 18, completing the fixation of the snap fastener 11. When disassembling, the operator only needs to use their fingers to push the locking block 15 back into the side groove 14 to remove the fastener 8. The operator only needs to press the fastener 8 to complete the fixation of the water supply pipe body 5. The installation is very convenient and simple, significantly improving the construction efficiency and convenience.

[0048] Working principle: During operation, the pipe trench 9 is cut according to the dimensions of the water supply pipe body 5. When pre-embedding the water supply pipe body 5, it can be fixed and tied to the transverse steel bar 3 with tie wire 7. Then, the template 4 can be fixed and installed in place with square timber and scaffolding. A steel reinforcement protective layer 12 is formed between the template 4 and the transverse steel bar 3 to form a pouring space. Part of the water supply pipe body 5 is located in the steel reinforcement protective layer 12, and the other part passes through the pipe trench 9 and extends out of the pipe trench 9. Then, the workers can use rubber strips 10 to insert between the pipe trench 9 and the water supply pipe body 5, and use fasteners 8 to clamp it. Once component 11 is fixed, the water supply pipe body 5 can be reinforced again. After the shear wall body 1 is poured and formed, the water supply pipe body 5 can be firmly embedded in the steel reinforcement protective layer 12 of the shear wall body 1, completing the pre-embedding of the water supply pipe body 5. This invention directly pre-embeds the water supply pipe body 5 into the shear wall body 1, eliminating the trouble of grooving, cleaning, fixing, and grouting. The forming quality is good, and it is more beautiful and neat. At the same time, the water supply pipe body 5 is located in the steel reinforcement protective layer 12. When the pressure test fails, it can be easily removed and replaced without damaging the structural integrity of the shear wall body 1. Replacement and maintenance are more convenient. Furthermore, the thickness of the rubber strip 10 is greater than the width of the gap between the water supply pipe body 5 and the pipe groove 9. When inserted, the rubber strip 10 deforms and seals the gap between the water supply pipe body 5 and the pipe groove 9, preventing grout leakage during pouring and thus avoiding the honeycomb and pitted surface problem of the shear wall body 1, further improving the molding quality. Additionally, when installing the fastener 8, the pressure ring 18 can be placed outside the water supply pipe body 5, the insertion hole 20 aligned with the insertion post 13, and the side plate 19 pressed down. The insertion post 13 passes through the insertion hole 20. During the process of the insertion post 13 passing through the insertion hole 20, the insertion hole 2... The angled opening 16 of the clamping block 15 is squeezed to allow the clamping block 15 to enter the side groove 14. The spring 17 is compressed and deformed until the clamping block 15 passes through the insertion hole 20. The spring 17 rebounds and pushes the clamping block 15 back to its original position, thus locking the side plate 19 and locking the pressure ring 18, completing the fixation of the clamping component 11. When disassembling, the worker only needs to use their fingers to push the clamping block 15 back into the side groove 14 to remove the fastener 8. The worker only needs to press the fastener 8 to complete the fixation of the water supply pipe body 5. The installation is very convenient and simple, significantly improving construction efficiency and convenience.
