Description

Technical Field

[0001] This application relates to the field of building technology, and in particular to a temporary support PVC pipe positioning structure for a post-cast strip cantilever structure. Background Technology

[0002] The published patent document CN222456796U discloses a temporary support PVC pipe positioning structure for a post-cast strip cantilever structure. The structure includes a beam slab, with a groove at the upper part of the beam slab forming the casting space. A lower PVC pipe is installed at the bottom of the beam slab. A through hole is located at the bottom of the beam slab corresponding to the top of the lower PVC pipe, and this through hole communicates with the center hole of the lower PVC pipe. A PVC pipe locator is installed at the upper part of the lower PVC pipe, comprising a lower PVC pipe connecting part and an upper PVC pipe positioning part. The lower PVC pipe connecting part extends into and fixes the lower PVC pipe, while the PVC pipe positioning part extends beyond the highest point of the beam slab. This design solves the technical problem in the prior art where the temporary supports above and below the beam slab cannot be accurately aligned, leading to misalignment and potential safety hazards.

[0003] Since PVC pipes of different diameters may be used as temporary supports at the construction site, the above devices may not be directly compatible in actual use, resulting in the need to prepare a variety of different specifications of locators, which leads to low construction efficiency. Therefore, this application provides a PVC pipe positioning structure for temporary support of post-cast strip cantilever structures. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a PVC pipe positioning structure for temporary support of post-cast strip cantilever structures. This structure overcomes the deficiencies of existing technologies and aims to solve the problem that, when PVC pipes of different diameters may be used as temporary supports at the construction site, the above devices may not be directly compatible in actual use, resulting in the need to prepare multiple positioning devices of different specifications and low construction efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a temporary support PVC pipe positioning structure for a post-cast strip cantilever structure, comprising a PVC pipe positioning part, an upper fixed seat fixedly installed at the bottom of the PVC pipe positioning part, a middle movable seat threadedly connected to the bottom of the PVC pipe positioning part below the upper fixed seat, a lower fixed seat rotatably connected to the bottom end of the PVC pipe positioning part, a first connecting rod fixedly installed between the four corners of the upper fixed seat and the lower fixed seat, a positioning mechanism provided on the outer periphery of the middle movable seat and the lower fixed seat, the positioning mechanism comprising several sets of rotating seats, several sets of rotating seats fixedly installed on the outside of the middle movable seat, a telescopic rod hinged to the middle of the rotating seat, several sets of fixed rods fixedly installed on the outside of the lower fixed seat, a support plate hinged to the telescopic end of the telescopic rod, and the bottom of the support plate hinged to the corresponding fixed rod.

[0006] By adopting the above technical solution, the PVC pipe positioning part is fixed to the bottom of the beam slab by a limiting mechanism, and the bottom of the PVC pipe positioning part extends out of the bottom of the beam slab. It is connected to the PVC pipe of the lower layer of the beam slab through the positioning mechanism. After the positioning mechanism is inserted into the interior of the lower layer of PVC pipe, the PVC pipe positioning part is rotated, causing the middle moving seat to descend under the action of the thread. The middle moving seat drives several sets of telescopic rods to move down, causing the telescopic rods to rotate and push the top of the support plate outward, so that the top of several sets of support plates abuts against the inner wall of the lower layer of PVC pipe for support. Then, concrete can be poured. At this time, a part of the top of the PVC pipe positioning part will still be exposed, which facilitates the positioning and installation of the PVC pipe at the top of the beam slab. By rotating the PVC pipe positioning part, the middle moving seat and positioning mechanism can be adjusted, which is beneficial for the application of PVC pipes of different diameters and improves construction efficiency.

[0007] As a preferred technical solution of this application, the limiting mechanism includes two sets of second connecting rods, which are respectively fixedly installed on both sides of the upper fixed seat. A retaining ring is fixedly installed at the end of the two sets of second connecting rods away from the upper fixed seat, and a retaining block is installed at the top of the retaining ring.

[0008] By adopting the above technical solution, an installation groove adapted to the retaining ring is opened above the PVC pipe in the lower layer inside the beam plate, so that the retaining ring is locked inside the beam plate. Four sets of blocks are locked above the beam plate to limit the retaining ring and the components connected to the limiting mechanism, thereby improving the stability of the device.

[0009] As a preferred technical solution of this application, two sets of upright plates are fixedly installed on the top of the upper fixing seat on both sides of the PVC pipe positioning part, and a plug rod is inserted between the two sets of upright plates. The PVC pipe positioning part has a through groove that matches the upright plate, and a nut is threaded to one end of the plug rod.

[0010] By adopting the above technical solution, after adjusting the positioning mechanism by rotating the PVC pipe positioning part, the insertion rod is inserted through the two sets of upright plates and the PVC pipe positioning part in the middle, and the nut is connected to the insertion rod, thereby completing the fixing of the insertion rod and the PVC pipe positioning part, and locking the PVC pipe positioning part, which improves the stability of the positioning mechanism after adjustment.

[0011] As a preferred technical solution of this application, a rotating cap is fixedly installed on the outer surface of the PVC pipe positioning part above the vertical plate.

[0012] By adopting the above technical solution, the rotating cap provides a hand action point for adjusting the PVC pipe positioning part, thus improving the practicality of adjusting the PVC pipe positioning part.

[0013] As a preferred technical solution of this application, anti-slip pads are fixedly installed at the bottom of each of the four sets of retaining rings.

[0014] By adopting the above technical solution, the friction between the block and the beam is increased by using anti-slip pads, thereby improving the stability of the limiting mechanism after it is connected to the beam.

[0015] As a preferred technical solution of this application, the four corners of the central movable seat are provided with guide holes that match the first connecting rod, and the central movable seat is slidably connected to the four sets of the first connecting rods through the four sets of guide holes.

[0016] By adopting the above technical solution, the central moving seat is slidably connected to four sets of first connecting rods through four sets of guide holes, so that the connecting rods play a guiding role when the central moving seat moves up and down, thereby improving the stability of the central moving seat when moving up and down.

[0017] As a preferred embodiment of this application, bearings are installed at the connection points between the upper fixing seat and the lower fixing seat and the PVC pipe positioning part.

[0018] By adopting the above technical solution, the bearing improves the smoothness of the connection between the PVC pipe positioning part and the upper and lower fixed seats when rotating, thus improving its practicality in use.

[0019] As a preferred technical solution of this application, the number of rotating seats and fixed rods is the same, and the number of rotating seats and fixed rods is at least 4 sets.

[0020] By adopting the above technical solution, at least four sets of rotating seats and fixed rods are provided to ensure good support for the PVC pipe through the corresponding rotating seats and fixed rods.

[0021] The beneficial effects of this application are:

[0022] 1. The PVC pipe positioning part is fixed to the bottom of the beam slab by a limiting mechanism, with the bottom of the PVC pipe positioning part extending beyond the bottom of the beam slab. It is connected to the PVC pipe of the lower layer of the beam slab through the positioning mechanism. After the positioning mechanism is inserted into the interior of the lower layer of PVC pipe, the PVC pipe positioning part is rotated, causing the middle moving seat to descend under the action of the thread. The middle moving seat drives several sets of telescopic rods to move down, causing the telescopic rods to rotate and push the top of the support plate outward, so that the top of several sets of support plates abuts against the inner wall of the lower layer of PVC pipe for support. Then, concrete can be poured. At this time, a part of the top of the PVC pipe positioning part will still be exposed, which facilitates the positioning and installation of the PVC pipe at the top of the beam slab. The middle moving seat and positioning mechanism can be adjusted by rotating the PVC pipe positioning part, which is beneficial for accommodating PVC pipes of different diameters and improving construction efficiency.

[0023] 2. An installation groove adapted to the retaining ring is opened inside the beam plate above the lower PVC pipe, so that the retaining ring is locked inside the beam plate. Four sets of blocks are used to lock the retaining ring and the components connected to the limiting mechanism above the beam plate, thereby limiting the retaining ring and improving the stability of the device.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A temporary support PVC pipe positioning structure for a post-cast strip cantilever structure includes a PVC pipe positioning part 1. An upper fixing seat 2 is fixedly installed at the bottom of the PVC pipe positioning part 1. A middle movable seat 3 is threadedly connected to the bottom of the PVC pipe positioning part 1 below the upper fixing seat 2. A lower fixing seat 4 is rotatably connected to the bottom end of the PVC pipe positioning part 1. First connecting rods 5 are fixedly installed between the four corners of the upper fixing seat 2 and the lower fixing seat 4. A positioning mechanism 7 is provided on the outer periphery of the middle movable seat 3 and the lower fixing seat 4. The positioning mechanism 7 includes several sets of rotating seats 701. All 701 are fixedly installed on the outside of the middle movable seat 3. The middle of the rotating seat 701 is hinged with a telescopic rod 702. Several sets of fixed rods 704 are fixedly installed on the outside of the lower fixed seat 4. The telescopic end of the telescopic rod 702 is hinged with a support plate 705. The bottom of the support plate 705 is hinged with the corresponding fixed rod 704. Two sets of upright plates 8 are fixedly installed on both sides of the top of the upper fixed seat 2 at the PVC pipe positioning part 1. Insert rods 9 are inserted between the two sets of upright plates 8. The inside of the PVC pipe positioning part 1 is provided with a through groove that matches the upright plate 8. One end of the insert rod 9 is threaded with a nut 10.

[0031] The PVC pipe positioning part 1 is fixed to the bottom of the beam slab by the limiting mechanism 6, and the bottom of the PVC pipe positioning part 1 extends out of the bottom of the beam slab. It is connected to the PVC pipe of the lower layer of the beam slab by the positioning mechanism 7. After the positioning mechanism 7 is inserted into the interior of the lower layer of PVC pipe, the PVC pipe positioning part 1 is rotated, causing the middle moving seat 3 to descend under the action of the thread. The middle moving seat 3 drives several sets of telescopic rods 702 to move down, causing the telescopic rods 702 to rotate and push the top of the support plate 705 to expand outward, so that the top of several sets of support plates 705 abuts against the inner wall of the lower layer of PVC pipe for support. Then concrete can be poured. At this time, the PVC pipe The top of the positioning part 1 will also have a part exposed, which facilitates the positioning and installation of the PVC pipe on the top of the beam. By rotating the PVC pipe positioning part 1, the middle moving seat 3 and the positioning mechanism 7 can be adjusted, which is beneficial for PVC pipes of different diameters and improves construction efficiency. After the positioning mechanism 7 is adjusted by rotating the PVC pipe positioning part 1, the insertion rod 9 is inserted through the two sets of upright plates 8 and the middle PVC pipe positioning part 1, and then the nut 10 is connected to the insertion rod 9, thereby completing the fixation of the insertion rod 9 and the PVC pipe positioning part 1, and completing the locking of the PVC pipe positioning part 1, which improves the stability of the positioning mechanism 7 after adjustment.

[0032] Reference Figure 1-3 The limiting mechanism 6 includes two sets of second connecting rods 601, which are fixedly installed on both sides of the upper fixed seat 2. A retaining ring 602 is fixedly installed at the end of the two sets of second connecting rods 601 away from the upper fixed seat 2, and a latching block 603 is installed at the top of the retaining ring 602. A rotating cap 11 is fixedly installed on the outer surface of the PVC pipe positioning part 1 above the vertical plate 8.

[0033] An installation groove for the retaining ring 602 is provided inside the beam plate above the lower PVC pipe, allowing the retaining ring 602 to be secured inside the beam plate. Four sets of interlocking blocks 603 are used to secure the retaining ring 602 and the components connected to the limiting mechanism 6, thereby improving the stability of the device. The rotating cap 11 provides a hand action point for adjusting the PVC pipe positioning part 1, improving the practicality of adjusting the PVC pipe positioning part 1.

[0034] Reference Figure 1-3 The bottom ends of the four sets of retaining rings 602 are all fixedly equipped with anti-slip pads 12; bearings 13 are installed at the connection between the upper fixing seat 2 and the lower fixing seat 4 and the PVC pipe positioning part 1; the anti-slip pads 12 increase the friction between the block 603 and the beam plate contact surface, improving the stability of the limiting mechanism 6 after it is connected to the beam plate; the bearings 13 improve the smoothness of the connection between the PVC pipe positioning part 1 and the upper fixing seat 2 and the lower fixing seat 4 when rotating, improving the practicality during use.

[0035] Reference Figure 1-3 The central movable seat 3 has guide holes 14 at each of its four corners that match the first connecting rod 5. The central movable seat 3 is slidably connected to the four sets of first connecting rods 5 through the four sets of guide holes 14. The number of rotating seats 701 and fixed rods 704 is the same, and the number of rotating seats 701 and fixed rods 704 is at least four sets. The central movable seat 3 is slidably connected to the four sets of first connecting rods 5 through the four sets of guide holes 14, so that the first connecting rods 5 play a guiding role when the central movable seat 3 moves up and down, thereby improving the stability of the central movable seat 3 when moving up and down. The rotating seats 701 and fixed rods 704 correspond to each other, and the at least four sets of rotating seats 701 and fixed rods 704 provide a good support effect for the PVC pipe.

[0036] Working principle: The PVC pipe positioning part 1 is fixed to the bottom of the beam slab by the limiting mechanism 6, and the bottom of the PVC pipe positioning part 1 extends out of the bottom of the beam slab. It is connected to the PVC pipe of the lower layer of the beam slab by the positioning mechanism 7. After the positioning mechanism 7 is inserted into the interior of the lower layer of PVC pipe, the PVC pipe positioning part 1 is rotated, causing the middle moving seat 3 to descend under the action of the thread. The middle moving seat 3 drives several sets of telescopic rods 702 to move down, causing the telescopic rods 702 to rotate and push the top of the support plate 705 to expand outward, so that the top of several sets of support plates 705 abuts against the inner wall of the lower layer of PVC pipe for support. Then, concrete is poured. At this time, the top of the PVC pipe positioning part 1 will still be exposed, which facilitates the positioning and installation of the PVC pipe on the top of the beam. By rotating the PVC pipe positioning part 1, the middle moving seat 3 and the positioning mechanism 7 can be adjusted, which is beneficial for the application of PVC pipes of different diameters and improves construction efficiency. An installation groove that matches the retaining ring 602 will be opened above the PVC pipe in the lower layer inside the beam, so that the retaining ring 602 is locked inside the beam. The retaining ring 602 and the components connected to the limiting mechanism 6 are limited by four sets of blocks 603 on the top of the beam, which improves the stability of the device.

[0037] After adjusting the positioning mechanism 7 by rotating the PVC pipe positioning part 1, the insertion rod 9 is inserted through the two sets of upright plates 8 and the PVC pipe positioning part 1 in the middle. Then, the nut 10 is connected to the insertion rod 9, thereby fixing the insertion rod 9 and the PVC pipe positioning part 1 and locking the PVC pipe positioning part 1. This improves the stability of the positioning mechanism 7 after adjustment. The rotating cap 11 provides a hand action point when adjusting the PVC pipe positioning part 1, thus improving the practicality of adjusting the PVC pipe positioning part 1.

[0038] Meanwhile, the friction between the anti-slip pad 12 and the contact surface between the block 603 and the beam plate is increased, which improves the stability of the limiting mechanism 6 after it is connected to the beam plate; the middle moving seat 3 is slidably connected to the four sets of first connecting rods 5 through four sets of guide holes 14, so that the first connecting rods 5 play a guiding role when the middle moving seat 3 moves up and down, which improves the stability of the middle moving seat 3 when it moves up and down.

[0039] In addition, the bearing 13 improves the smoothness of the connection between the PVC pipe positioning part 1 and the upper fixed seat 2 and the lower fixed seat 4 when rotating, thus improving its practicality during use; the rotating seat 701 and the fixed rod 704 correspond to each other, and at least four sets of rotating seats 701 and fixed rods 704 provide good support for the PVC pipe.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
