Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a BIM-based prefabricated building pipeline support and hanger equipment and its construction method. Background Technology

[0002] Building Information Modeling (BIM) is a three-dimensional building model built on the basis of various relevant information and data of a building project. It simulates the real information of the building through digital information, realizes project supervision, improves project production efficiency, enhances building quality, shortens construction period, and reduces construction costs.

[0003] BIM-based prefabricated building pipeline supports are devices used for the installation and fixing of pipelines such as water pipes, cables, and air conditioning ventilation pipes in buildings. In the current technology, more than 95% of building pipeline supports are installed by on-site fabrication methods. Installers cut, weld, assemble, and fix angle iron, channel steel, I-beams, and other profiles on the construction site to the building.

[0004] Traditional load-bearing supports only consider the vertical gravity and their load-bearing function. However, under the influence of factors such as earthquakes, the pipeline system will generate a huge horizontal seismic force. At this time, the pipeline and auxiliary electromechanical equipment are very easy to be damaged and malfunction due to the lack of horizontal protection.

[0005] The aforementioned traditional prefabricated building pipeline support brackets also have the following disadvantages during use: When in use, the pipeline is supported by the hanger rod to prevent it from falling, but when vibration occurs, the pipeline will rub against the corner of the hanger rod, which can easily damage the pipeline after long-term use. Furthermore, when replacing the pipeline, it needs to be removed, which is inconvenient to use. Summary of the Invention

[0006] In view of this, in order to solve the problems of traditional prefabricated building pipeline support and hanger systems that rely on hangers to support the pipeline during use, causing friction between the pipeline and the corners of the hangers during vibration, which can easily damage the pipeline over time, and requiring dismantling when replacing the pipeline, the present invention provides a BIM-based prefabricated building pipeline support and hanger system and its construction method.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A BIM-based prefabricated building pipeline support and hanger equipment includes a splicing support and hanger, with an installation plate fixedly provided on the top of the splicing support and hanger for installation, and a T-shaped seat provided inside the splicing support and hanger, with a clamping mechanism for clamping the pipeline on the top of the T-shaped seat.

[0009] A shock-absorbing mechanism is provided between the bottom inner wall of the T-shaped seat and the splicing support to dampen and buffer the pipelines on the T-shaped seat;

[0010] The splicing support consists of two sets of support rods and a second sliding rod, as well as multiple insert plates. The second sliding rod is slidably installed inside the support rod. A positioning bolt is threaded through one side of the support rod, and multiple positioning holes that cooperate with the positioning bolt are opened on one side of the second sliding rod for adjusting the height.

[0011] The top of the support rod is provided with a first rotating seat via a pin. The top of the first rotating seat and the bottom of the second sliding rod are both fixed with connecting blocks. Multiple insert plates are spliced ​​and fixed between the two sets of connecting blocks. By pulling the pin, one of the support rods and the first rotating seat are separated, and the spliced ​​support bracket is opened to place the pipeline.

[0012] The air duct has connecting ears fixed on both sides, and the connecting ears are fixed to the corresponding insert plates by fastening bolts.

[0013] Furthermore, the clamping mechanism includes connecting plates fixedly connected to both sides of the T-shaped seat. A first sliding rod is slidably provided through the top of the connecting plates. Multiple first arc-shaped clamping blocks are fixedly provided on the top of the T-shaped seat. A second arc-shaped clamping block that is offset from the first arc-shaped clamping block is fixedly provided at the bottom of the first sliding rod. A return spring is sleeved on the outer wall of the first sliding rod. The two ends of the return spring are fixedly connected to the outer wall of the first sliding rod and the top of the connecting plate, respectively. A rotating shaft is rotatably provided through one side of the T-shaped seat via a one-way bearing. An eccentric wheel that cooperates with the first sliding rod is sleeved on the outer wall of the rotating shaft.

[0014] Furthermore, a first fixed ring corresponding to the eccentric wheel is fixedly sleeved on the outer wall of the rotating shaft, and a sliding ring located on one side of the eccentric wheel is slidably sleeved on the outer wall of the rotating shaft. A positioning post is fixedly installed on one side of the sliding ring, and multiple slots that cooperate with the positioning post are opened on one side of the eccentric wheel. Multiple second springs are sleeved on the outer wall of the rotating shaft, and the two ends of the second springs are fixedly connected to the corresponding sliding rings and the adjacent sides of the first fixed rings.

[0015] Furthermore, a second fixing ring is fitted on the outer wall of the rotating shaft on the other side of the eccentric wheel, and a torsion spring is fitted on the outer wall of the rotating shaft on one side of the second fixing ring. The two ends of the torsion spring are fixedly connected to the second fixing ring and the side of the eccentric wheel that are close to each other, respectively.

[0016] Furthermore, the shock absorption mechanism includes a shock absorption frame disposed between the T-shaped seat and the lower insert plate. The top of the shock absorption frame has a first rectangular hole, and two piston blocks are slidably disposed on the inner wall of the first rectangular hole. The two piston blocks are fixedly connected to the corresponding T-shaped seat and insert plate respectively, and a receiving cavity for holding nitrogen is formed between the two piston blocks and the first rectangular hole.

[0017] Furthermore, two second rectangular holes are opened on one side of the shock absorber frame. A guide rod is fixedly installed in the second rectangular hole. A sliding block is slidably fitted on the outer wall of the guide rod. A first spring is fitted on the outer wall of the guide rod. The two ends of the first spring are fixedly connected to the second rectangular hole and the sliding block respectively on the side close to each other. Two rotating rods are rotatably installed on both sides of the sliding block. A second rotating seat is rotatably installed on the other end of the rotating rod. The two sets of second rotating seats are fixedly connected to the T-shaped seat and the insert plate respectively on the side close to each other.

[0018] Furthermore, one end of one of the connecting blocks and the insert plate is fixedly provided with a stud, and one side of the other connecting block and the insert plate is provided with a threaded hole corresponding to the stud.

[0019] A construction method for prefabricated building pipeline support and hanger equipment based on BIM includes the following steps:

[0020] S1. Assemble the splicing supports according to the number of pipelines, and install the mounting plate at the location of the information collected by BIM;

[0021] S2. Pull out one of the pins to open the splicing support, place the pipelines on the first arc-shaped clamp, and then close the splicing support through the pin.

[0022] S3. Rotating the rotating shaft drives the eccentric wheel to rotate, which in turn moves the first sliding rod downward, causing the second arc-shaped clamp and the first arc-shaped clamp to clamp the pipeline.

[0023] S4. Secure the plate to the bottom using the fastening bolts and connecting lugs. Installation complete.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The prefabricated building pipeline support and hanger equipment based on BIM disclosed in this invention, through the setting of the clamping mechanism, can drive the eccentric wheel to rotate by rotating the rotating shaft. When the eccentric wheel rotates, it can drive the second arc-shaped clamping block to move downward through the first sliding rod to clamp the pipeline in conjunction with the first arc-shaped clamping block. It can fix pipelines of different sizes and can fix pipelines of the same size at the same time, thereby improving the fixing effect.

[0026] 2. The prefabricated building pipeline support and hanger equipment based on BIM disclosed in this invention, through the setting of the shock absorption mechanism, when vibration occurs, the pipeline will drive the T-shaped seat to move downward, so that the two piston blocks will move closer to each other and squeeze the nitrogen in the receiving cavity. At the same time, the rotating rod will drive the sliding block to slide and squeeze the first spring, so as to dampen the pipeline and prevent the pipeline from pulling on the splicing support and hanger during vibration, thereby improving its service life.

[0027] 3. The prefabricated building pipeline support and hanger equipment based on BIM disclosed in this invention allows the supports and hangers to be installed in different positions by setting them in a spliced ​​manner, ensuring that they are parallel and avoiding large height differences. In addition, by setting the supports and hangers in a spliced ​​manner, they can be opened, so that the supports and hangers do not need to be disassembled when installing pipelines or replacing the entire pipeline later, thus improving maintenance efficiency.

[0028] 4. The prefabricated building pipeline support device based on BIM disclosed in this invention can fix pipelines of different sizes by setting the second arc-shaped clamp and the first arc-shaped clamp, preventing the pipeline from rubbing against the T-shaped seat during vibration, and can reduce vibration by setting the first spring and nitrogen gas, thereby improving its service life.

[0042] Reference Figures 1-7 The diagram shows a BIM-based prefabricated building pipeline support and hanger equipment. The top of the splicing support and hanger 1 is fixed with an installation plate 2 for installation, and the interior of the splicing support and hanger 1 is provided with a T-shaped seat 4.

[0043] The splicing support bracket 1 consists of two sets of support rods 12 and a second sliding rod 13, as well as multiple insert plates 18. The second sliding rod 13 is slidably disposed inside the support rod 12. A positioning bolt 15 is threaded through one side of the support rod 12. Multiple positioning holes 14 are opened on one side of the second sliding rod 13 to cooperate with the positioning bolt 15 for adjusting the height of the support rod 12.

[0044] The top of the support rod 12 is provided with a first rotating seat 11 via a pin. The top of the first rotating seat 11 and the bottom of the second sliding rod 13 are both fixed with connecting blocks 10. Multiple insert plates 18 are sequentially spliced ​​and fixed between the two sets of connecting blocks 10. By pulling the pin, one of the support rods 12 and the first rotating seat 11 are separated, and the splicing support bracket 1 is opened to place the pipeline.

[0045] Both sides of the duct 3 are fixed with connecting ears 19. The connecting ears 19 are fixedly connected to the corresponding insert plates 18 by fastening bolts 20. By pulling the pin, one of the support rods 12 can be separated from the first rotating seat 11, and one side of the splicing support 1 can be opened to facilitate the placement of pipelines. The pipeline can be fixed on the T-shaped seat 4 by the clamping mechanism. At the same time, during use, the shock absorption mechanism can provide shock absorption and buffer for the pipeline and the splicing support 1, thereby improving their service life.

[0046] The top of the T-shaped seat 4 is provided with a clamping mechanism for clamping pipelines. The clamping mechanism includes connecting plates 6 fixedly connected to both sides of the T-shaped seat 4. A first sliding rod 8 is slidably provided through the top of the connecting plate 6. Multiple first arc-shaped clamping blocks 5 are fixedly provided on the top of the T-shaped seat 4. A second arc-shaped clamping block 7, which is offset from the first arc-shaped clamping block 5, is fixedly provided at the bottom of the first sliding rod 8. A return spring 21 is sleeved on the outer wall of the first sliding rod 8. The two ends of the return spring 21 are fixedly connected to the outer wall of the first sliding rod 8 and the top of the connecting plate 6, respectively. A rotating shaft 22 is rotatably provided through one side of the T-shaped seat 4 via a one-way bearing 33. An eccentric wheel 9, which works with the first sliding rod 8, is sleeved on the outer wall of the rotating shaft 22. Rotating the rotating shaft 22 can drive the eccentric wheel 9 to rotate. When the eccentric wheel 9 rotates, it can drive the second arc-shaped clamping block 7 to move downward through the first sliding rod 8 to cooperate with the first arc-shaped clamping block 5 to clamp the pipeline.

[0047] A shock-absorbing mechanism is provided between the bottom inner wall of the T-shaped seat 4 and the splicing support 1 to dampen the pipeline on the T-shaped seat 4. The shock-absorbing mechanism includes a shock-absorbing frame 23 disposed between the T-shaped seat 4 and the lower insert plate 18. The top of the shock-absorbing frame 23 has a first rectangular hole 24. Two piston blocks 25 are slidably disposed on the inner wall of the first rectangular hole 24. The two piston blocks 25 are fixedly connected to the corresponding T-shaped seat 4 and insert plate 18, respectively. A receiving cavity 26 for holding nitrogen is formed between the two piston blocks 25 and the first rectangular hole 24. By placing nitrogen in the shock-absorbing frame 23, the pipeline can be buffered when it moves downward due to vibration, preventing the pipeline vibration from pulling on the splicing support 1.

[0048] Two second rectangular holes 27 are opened on one side of the shock absorber 23. A guide rod 28 is fixedly installed in the second rectangular hole 27. A sliding block 29 is slidably fitted on the outer wall of the guide rod 28. A first spring 30 is fitted on the outer wall of the guide rod 28. The two ends of the first spring 30 are fixedly connected to the second rectangular hole 27 and the sliding block 29 respectively on their respective adjacent sides. Two rotating rods 31 are rotatably installed on both sides of the sliding block 29. A second rotating seat 32 is rotatably installed on the other end of the rotating rod 31. The two sets of second rotating seats 32 are fixedly connected to the T-shaped seat 4 and the insert plate 18 respectively on their respective adjacent sides. When the T-shaped seat 4 is subjected to vibration, it moves downward. The rotating rods 31 can drive the sliding block 29 to move on the second rectangular hole 27, which can compress the guide rod 28, thereby achieving a shock absorption effect.

[0049] refer to Figure 3 , Figure 6 and Figure 7 The outer wall of the rotating shaft 22 is fixedly fitted with a first fixed ring 34 corresponding to the eccentric wheel 9. The outer wall of the rotating shaft 22 is slidably fitted with a sliding ring 35 located on one side of the eccentric wheel 9. A positioning post 37 is fixedly fitted on one side of the sliding ring 35. A plurality of slots that cooperate with the positioning post 37 are opened on one side of the eccentric wheel 9. A plurality of second springs 36 are fitted on the outer wall of the rotating shaft 22. The two ends of the second springs 36 are fixedly connected to the corresponding sliding ring 35 and the side of the first fixed ring 34 that are close to each other. When there is a thinner wire in the pipeline, the corresponding sliding ring 35 is pushed to move, so that the positioning post 37 moves away from the slot. Then the eccentric wheel 9 is manually rotated to drive the first sliding rod 8 to move downward to clamp the wire.

[0050] The outer wall of the rotating shaft 22 is fitted with a second fixing ring 39 located on the other side of the eccentric wheel 9. The outer wall of the rotating shaft 22 is fitted with a torsion spring 38 located on one side of the second fixing ring 39. The two ends of the torsion spring 38 are fixedly connected to the second fixing ring 39 and the eccentric wheel 9 respectively. By setting the torsion spring 38, the eccentric wheel 9 can be automatically reset when the positioning pin 37 moves away from the eccentric wheel 9, which makes it easy to adjust the positions of multiple eccentric wheels 9 to be consistent.

[0051] One end of each of the connecting block 10 and the insert plate 18 is fixed with a stud 17, and the other connecting block 10 and the insert plate 18 are provided with threaded holes 16 corresponding to the stud 17 on one side. The stud 17 and the threaded holes 16 are designed to facilitate splicing and improve installation efficiency.

[0052] When using the BIM-based prefabricated building pipeline support and hanger equipment, according to the information obtained from BIM, an appropriate number of insert plates 18 are installed on one side of the connecting block 10, the mounting plate 2 is installed in the appropriate position, and then the pin on one side is pulled to disengage one of the support rods 12 from the first rotating seat 11. At this time, the support rod 12 on the other side can rotate, so that the splicing support and hanger 1 is opened. Then, the line body is placed on the corresponding first arc-shaped clamp 5 in sequence. After the placement is completed, the splicing support and hanger 1 is closed by the pin.

[0053] Next, rotating the rotating shaft 22 drives the eccentric wheel 9 to rotate, causing the first sliding rod 8 to move downward, so that the second arc-shaped clamp 7 and the first arc-shaped clamp 5 clamp the pipeline. When the pipeline is not clamped, push the sliding ring 35 to move the positioning pin 37 away from the eccentric wheel 9. Manually rotate the eccentric wheel 9 to drive the first sliding rod 8 to continue to descend until the second arc-shaped clamp 7 and the first arc-shaped clamp 5 completely clamp the pipeline. Then release the sliding ring 35, and push the positioning pin 37 to lock on one side of the eccentric wheel 9 through the second spring 36. Finally, fix it to the bottom of the insert plate 18 by fastening the bolt 20 and connecting ear 19, and the installation is completed.

[0054] When the height needs to be adjusted, rotate the positioning bolt 15 so that the positioning bolt 15 moves away from the positioning hole 14. At this time, the second sliding rod 13 moves telescopically within the support rod 12. After the adjustment is completed, it is fixed by the positioning bolt 15.

[0055] When vibration occurs during use, the pipeline will cause the T-shaped seat 4 to move downward, so that the two piston blocks 25 move closer to each other and squeeze the nitrogen in the receiving cavity 26. At the same time, the rotating rod 31 will drive the sliding block 29 to slide and squeeze the first spring 30, so that it can dampen the pipeline and improve the service life of the pipeline.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
