Technical Field
[0001] This utility model relates to the field of pipe support technology, and in particular to a horizontal pre-embedded pipe support for a subway C-shaped steel chute. Background Technology
[0002] Urban rail transit projects involve complex electromechanical systems, requiring the installation and fixing of numerous devices and pipelines on reinforced concrete structures. To facilitate the installation and fixing of these systems and pipelines, steel grooves are typically pre-embedded in the reinforced concrete structure. These pre-embedded grooves are primarily used in rail transit projects to facilitate the later installation of pipeline supports.
[0003] Currently, existing pipe supports, when assembled with C-shaped steel chutes, cannot adjust their position according to the pipe's direction, resulting in low installation accuracy and poor stability. Therefore, in order to improve the installation effect of pipe supports and to promote technological progress in the industry and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from the existing technology in terms of structure and application. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of existing pipe supports, which cannot adjust the position of the pipe support according to the direction of the pipe when assembled with C-shaped steel chutes, resulting in low installation accuracy and poor stability. Therefore, this utility model proposes a horizontal pre-embedded pipe support for subway C-shaped steel chutes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A C-shaped steel chute for horizontally embedded pipe support in subway systems includes a C-shaped chute. The bottom inner wall of the C-shaped chute has two sets of first toothed grooves. Two sliders are horizontally slidably connected to the bottom of the C-shaped chute, and the sliders can slide up and down within the C-shaped chute. The bottom of each slider has two sets of second toothed grooves that mesh with the first toothed grooves. The bottom of each slider is rotatably connected to two pipe supports via pins, and the two pipe supports are fixed together by bolts. An adjusting screw is threaded onto each slider, and a rotating disk is rotatably connected to the top of the adjusting screw. The rotating disk rests against the top inner wall of the C-shaped chute, and an adjusting knob is fixedly connected to the bottom of the adjusting screw.
[0006] Furthermore, the C-shaped slide is provided with multiple mounting holes between the top and bottom, and a pull rod is inserted into two of the mounting holes. The bottom of the pull rod is provided with a threaded groove, and a fastening nut and an adjusting nut are threadedly connected to the threaded groove of the pull rod. The C-shaped slide is located between the fastening nut and the adjusting nut.
[0007] Furthermore, the bottom of the C-shaped groove is provided with two gaskets, and the bottom end of the pull rod passes through the gaskets.
[0008] Furthermore, the outer wall of the pull rod is fixedly connected with multiple limiting discs, and the limiting discs are provided with multiple through holes.
[0009] Furthermore, the inner wall of the pipe support is bonded with a gasket.
[0010] Furthermore, both ends of the top of the C-shaped chute are fixedly connected to anti-seismic connectors, and the other end of the anti-seismic connector is rotatably connected to an anti-seismic diagonal brace.
[0011] Furthermore, an expansion bolt is inserted into the other end of the seismic brace.
[0012] The beneficial effects of this utility model are as follows: 1. By pushing the slider upwards, the second toothed groove separates from the first toothed groove. Then, by pulling the slider horizontally, the pipe support moves, thereby adjusting the position of the pipe support. This allows the position of the pipe support to be adjusted according to the direction of the pipe, improving the installation accuracy.
[0013] 2. Adjust the height of the C-shaped slide by pulling it along the pull rod. Then, tighten the adjusting nut and the fastening nut to fix the height of the C-shaped slide, thereby improving the applicability of the installation. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figures 1-4 A C-shaped steel chute horizontal pre-embedded pipe support for subways includes a C-shaped chute 1. The bottom inner wall of the C-shaped chute 1 is provided with two sets of first toothed grooves 10. The bottom of the C-shaped chute 1 is horizontally slidably connected with two sliders 11, and the sliders 11 can slide up and down in the C-shaped chute 1. The bottom of the sliders 11 is provided with two sets of second toothed grooves 12, and the second toothed grooves 12 can mesh with the first toothed grooves 10. The bottom of the slider 11 is rotatably connected to two pipe supports 13 via a pin, and the two pipe supports 13 are fixed together by bolts; The slider 11 is threadedly connected to an adjusting screw 15, and the top of the adjusting screw 15 is rotatably connected to a rotating disk 16. After adjustment, the rotating disk 16 can abut against the top inner wall of the C-shaped slide groove 1. The bottom of the adjusting screw 15 is welded with an adjusting knob 17. First, turn the adjustment knob 17 so that the rotating disk 16 is close to the top outer wall of the slider 11. Then push the slider 11 upward as a whole so that the second tooth groove 12 is separated from the first tooth groove 10. Next, move the slider 11 horizontally to move the pipe support 13, thereby adjusting the position of the pipe support 13. Then lower the slider 11 as a whole so that the second tooth groove 12 and the first tooth groove 10 are engaged again. Continue turning the adjustment knob 17 to raise the rotating disk 16 until it rests against the top inner wall of the C-shaped slide 1. Tighten the adjustment screw 15 so that the slider 11 cannot move upward as a whole, thereby fixing the position of the pipe support 13.
[0018] Multiple mounting holes 2 are provided between the top and bottom of the C-shaped slide 1. Two of the mounting holes 2 are fitted with pull rods 3, which pull the C-shaped slide 1 to move along the pull rods 3, thereby adjusting the height of the C-shaped slide 1. The bottom of the pull rod 3 is provided with a threaded groove 4. A fastening nut 8 and an adjusting nut 9 are threadedly connected to the threaded groove 4 of the pull rod 3. The C-shaped slide 1 is located between the fastening nut 8 and the adjusting nut 9. Tightening the adjusting nut 9 and the fastening nut 8 fixes the height of the C-shaped slide 1.
[0019] The bottom of the C-shaped slide 1 is provided with two gaskets 7. The bottom end of the pull rod 3 passes through the gaskets 7. The gaskets are made of elastic or rigid material to distribute the pressure of the adjusting nut 9 and the fastening nut 8 on the C-shaped slide 1, so as to avoid deformation of the bottom of the C-shaped slide 1 and prevent the adjusting nut 9 from loosening.
[0020] Multiple limiting discs 5 are welded to the outer wall of the tie rod 3. The limiting discs 5 increase the contact area between the tie rod 3 and the structure, thereby improving the stability of the fixation. Multiple through holes 6 are provided on the limiting discs 5.
[0021] The inner wall of the pipe support 13 is bonded with a gasket 14 made of elastic and wear-resistant materials such as rubber and polyurethane, which increases the friction between the pipe and the support, prevents the pipe from sliding, and buffers the vibration of the subway during operation, reducing pipe wear.
[0022] Both ends of the top of the C-shaped chute 1 are fixed with seismic connectors 18 by bolts. The other end of the seismic connector 18 is rotatably connected to a seismic brace 19. When the subway runs and vibrates, the seismic brace 19 reduces vibration through its own rigid support and rotatable connection.
[0023] An expansion bolt 20 is inserted into the other end of the seismic brace 19.
[0024] The working principle of this embodiment is as follows: When in use, the tie rod 3 is embedded in the pre-embedded area of the subway structure, and the expansion bolt 20 is screwed into the subway structure to fix the bracket. Loosen the fastening nut 8 and the adjusting nut 9, then pull the C-shaped slide 1 along the pull rod 3 to adjust the height of the C-shaped slide 1. Then, tighten the adjusting nut 9 and the fastening nut 8 to fix the height of the C-shaped slide 1. The level can be adjusted by placing a level on the C-shaped slide 1 and observing the bubble. Then, turn the adjustment knob 17 and loosen the adjustment screw 15 so that the rotating disk 16 is close to the slider 11. Then push the slider 11 upward as a whole so that the second tooth groove 12 is separated from the first tooth groove 10. Then, move the slider 11 horizontally to drive the pipe support 13 to move, thereby adjusting the position of the pipe support 13. Next, pull down the slider 11 so that the second tooth groove 12 engages with the first tooth groove 10, and then turn the adjustment knob 17 in the opposite direction so that the rotating disk 16 abuts against the top inner wall of the C-shaped slide groove 1. Continue to turn the adjustment knob 17 and tighten the adjustment screw 15 so that the slider 11 cannot move upward, thereby fixing the position of the pipe support 13. Then, the pipe is inserted between the two pipe supports 13, and the two pipe supports 13 are fixed together with bolts to install the pipe.
