Description

Technical Field

[0001] This utility model belongs to the field of gas riser support technology, and in particular relates to a fixed support for gas risers in high-rise buildings. Background Technology

[0002] With the acceleration of urbanization and a significant increase in the number of high-rise buildings, the safe installation and long-term stable operation of gas risers, a core energy supply method, have become critical requirements for both building engineering and the gas industry. Currently, gas risers in high-rise buildings are mostly installed on the exterior walls using fixed supports. Traditional supports generally employ a basic structure of "angle steel + U-shaped clamps," which only fulfills the function of fixing the risers. In practical applications, this has gradually revealed several technical defects, making it difficult to meet the needs of complex outdoor usage scenarios. Gas risers in high-rise buildings are laid along the exterior walls. The supports on lower floors can easily become support points for people (especially children or non-professionals) to climb. Traditional supports have no anti-climbing structure design, which may not only cause people to fall and get injured, but may also cause safety accidents such as loose pipe joints and gas leaks due to collisions and shaking of the risers during climbing.

[0003] The gaps and corners of outdoor pipe supports are easy for birds (such as sparrows and pigeons) to build nests. The branches, weeds, feathers and other debris in the nests may block the gas pipe valves or exhaust ports. At the same time, bird droppings are highly corrosive and will accelerate the corrosion of the metal parts of the support (such as angle steel and bolts), shorten the service life of the support, and increase the cost and frequency of later maintenance.

[0004] Therefore, it is essential to invent a fixed support for gas risers in high-rise buildings. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gas riser fixing bracket for high-rise buildings, including a wall plate, a pipe support plate, a nut, a clamp, a gas riser, a screw seat, anti-climbing spiked bamboo, bird-repelling spiked bamboo, and spiked branches. The wall plate is fixedly installed on the building wall by expansion bolts. The pipe support plate is welded and fixedly installed on the wall plate. The pipe support plate is fixedly connected to the gas riser by nuts and clamps. The anti-climbing spiked bamboo and bird-repelling spiked bamboo are respectively installed on the pipe support plate by screw seats. Each anti-climbing spiked bamboo and bird-repelling spiked bamboo is provided with numerous spiked branches.

[0006] Preferably, the pipe support plate is an "L"-shaped angle steel plate structure, wherein the vertical part has a connecting hole that allows the U-shaped clamp to pass through, and at least three screw seats are installed on the upper and lower surfaces of the horizontal part, and the clamp has threads at both ends that engage with nuts.

[0007] Preferably, the screw seat is engaged with the lower end of the corresponding anti-climbing bamboo or bird-repelling bamboo, and the ends of the anti-climbing bamboo and bird-repelling bamboo are provided with studs that match the screw seat.

[0008] Preferably, the axes of both the anti-climbing spiked bamboo and the bird-repelling spiked bamboo are perpendicular to the ground, and both adopt a pointed conical rod structure. The bird-repelling spiked bamboo is threadedly connected to the screw seat above the pipe support plate, and the anti-climbing spiked bamboo is threadedly connected to the screw seat below the pipe support plate.

[0009] Preferably, each of the anti-climbing or bird-repelling thorny bamboos has several sharp branches arranged alternately, and the angle between the axis of the sharp branches and the axis of the anti-climbing or bird-repelling thorny bamboo is less than 90 degrees.

[0010] Preferably, the spiked branches are obliquely arranged on the anti-climbing or bird-repelling bamboo, and the spiked branches have a bamboo shoot-shaped structure. The spiked branches on the anti-climbing and bird-repelling bamboo do not contact or interfere with the surrounding structures.

[0011] Preferably, the surfaces of the anti-climbing thorny bamboo, the bird-repelling thorny bamboo, and the spiked branches are coated with a dark dye, wherein the surfaces of the anti-climbing thorny bamboo and the bird-repelling thorny bamboo are coated with a yellow dye, and the surfaces of the spiked branches provided on both are coated with a red dye.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model's anti-climbing spiked bamboo and bird-repelling spiked bamboo are both connected to the pipe support plate by screw seats, and are detachable structures. When a single spiked bamboo is rusted, damaged, or the spikes are worn, it is not necessary to disassemble the entire support. The corresponding spiked bamboo can be replaced simply by unscrewing it. The operation is simple and does not require interruption of gas supply, which greatly improves maintenance efficiency and reduces the time and labor costs of later operation and maintenance.

[0013] This utility model uses screw seats to install anti-climbing spikes on the lower surface of the pipe support plate. The vertically arranged pointed cone-shaped rods and the inclined bamboo shoot-shaped spikes form a dense protective area, which can effectively prevent people from climbing and avoid the risk of personnel safety and pipeline damage caused by climbing from the source.

[0014] This invention uses a screw seat to install bird-repelling spiked bamboo on the upper surface of the pipe support plate. The staggered distribution of the spiked branches also interferes with birds staying and nesting near the support, preventing debris from clogging the pipe and bird droppings from corroding the parts, reducing maintenance costs, and extending the service life of the support and riser.

[0020] As attached Figure 1 To be continued Figure 2 As shown: This utility model provides a fixed support for a gas riser in a high-rise building, comprising a wall plate 1, a pipe support plate 2, a nut 3, a clamp 4, a gas riser 5, a screw seat 6, anti-climbing spiked bamboo 7, bird-repelling spiked bamboo 8, and spiked branches 9. The wall plate 1 is fixedly installed on the building wall by expansion bolts. The pipe support plate 2 is welded and fixedly installed on the wall plate 1. The pipe support plate 2 is fixedly connected to the gas riser 5 by the nut 3 and the clamp 4. The anti-climbing spiked bamboo 7 and bird-repelling spiked bamboo 8 are respectively installed on the pipe support plate 2 by the screw seat 6. Each anti-climbing spiked bamboo 7 and bird-repelling spiked bamboo 8 is provided with numerous spiked branches 9.

[0021] Furthermore, the pipe support plate 2 is made of Q235 low-carbon steel "L"-shaped angle steel plate to meet the load-bearing requirements of the gas riser 5 in high-rise buildings (load-bearing capacity not less than 50kg). The vertical part of the pipe support plate 2 has two circular connection holes along the vertical direction. The diameter of the connection holes is 1-2mm larger than the diameter of the U-shaped clamp 4 (for example, if the clamp's diameter is 8mm, the hole diameter is set to 9mm), ensuring that the clamp 4 can pass through smoothly and has a small adjustment range. At least three screw seats 6 are fixedly installed on the upper and lower surfaces of the horizontal part of the pipe support plate 2 using a full welding process. The screw seats 6 are evenly spaced along the length of the horizontal part (spacing 100-150mm), and the screw seats 6 on the upper and lower surfaces are symmetrically distributed to avoid uneven stress on the pipe support plate 2 after installation. The U-shaped clamp 4 is made of 304 stainless steel (resistant to outdoor corrosion). The surfaces of its two ends are machined with external threads (specifications M8-M12). These external threads can engage with the nut 3 (matching hexagonal nut, material same as clamp 4). During assembly, the arc-shaped section of clamp 4 fits against the outer wall of gas riser 5. After the two ends of the clamp pass through the connection holes of the vertical part of pipe support plate 2, tighten the nut 3 to firmly clamp the gas riser 5 on the inner side of the vertical part of pipe support plate 2, while leaving a gap of 0.5-1mm to accommodate the displacement caused by thermal expansion and contraction of the pipe.

[0022] Furthermore, the screw seat 6 is a cylindrical structure with an internally threaded hole. The internal thread specification (M10-M14) is matched with the studs at the lower ends of the anti-climbing spiked bamboo 7 and the bird-repelling spiked bamboo 8. The lower ends of both the anti-climbing spiked bamboo 7 and the bird-repelling spiked bamboo 8 are integrally formed with cylindrical studs (the diameter of which matches the internal thread of the screw seat). The surface of the studs is machined with external threads. During assembly, align the stud at the lower end of the anti-climbing spiked bamboo 7 with the internal threaded hole of the screw seat 6 below the pipe support plate 2, and screw it in clockwise until the stud is fully inserted into the screw seat 6 (the screwing depth is equal to the length of the stud), thus fixing the anti-climbing spiked bamboo 7. Similarly, align the stud at the lower end of the bird-repelling spiked bamboo 8 with the screw seat 6 above the pipe support plate 2, and tighten it in the same way. This threaded connection method not only ensures the stability of the spiked bamboo after installation (pull-out resistance not less than 10kg), but also allows for individual disassembly and replacement of the spiked bamboo when it is damaged, without disassembling the entire bracket.

[0023] Furthermore, both the anti-climbing bamboo 7 and bird-repelling bamboo 8 are made of 201 stainless steel (balancing strength and lightweight, with a single piece weighing no more than 200g). Both are perpendicular to the ground to prevent a reduction in the protective area due to tilting. Both feature a tapered pole structure, with the pole diameter gradually decreasing from 12-15mm at the bottom (where it connects to the screw base) to 5-8mm at the top. This gradual reduction enhances the pole's bending resistance while reducing wind resistance (suitable for strong winds in high-rise buildings). Among them, the bird-repelling spiked bamboo 8 is threadedly connected to the screw seat 6 above the pipe support plate 2 in a one-to-one correspondence. The height of a single bird-repelling spiked bamboo 8 is set to 150-200mm. After installation, its upper end does not exceed the center line of the gas riser 5 to avoid obstructing the pipe valve. The anti-climbing spiked bamboo 7 is threadedly connected to the screw seat 6 below the pipe support plate 2 in a one-to-one correspondence. The height of a single anti-climbing spiked bamboo 7 is set to 200-250mm. After installation, the distance between its lower end and the adjacent support below is not less than 300mm, forming a continuous anti-climbing barrier. Both the anti-climbing spiked bamboo 7 and the bird-repelling spiked bamboo 8 maintain a distance of 20-25mm from the gas riser 5 and a distance of 30-35mm from the building wall to avoid contact and interference with other structures.

[0024] Furthermore, each anti-climbing bamboo 7 or bird-repelling bamboo 8 has 8-12 staggered spiked branches 9 welded together using a welding process. These spiked branches 9 are made of 201 stainless steel and are plug-welded to the pole to ensure connection strength (bending resistance not less than 5kg). The angle between the axis of the spiked branch 9 and the axis of the anti-climbing bamboo 7 or bird-repelling bamboo 8 is set at 60-80° (less than 90°), and the angles of adjacent spiked branches 9 are evenly distributed (staggered vertically and horizontally). For example, spiked branches 9 on the same horizontal plane are arranged every 90° along the circumference of the pole, with a vertical spacing of 30-40mm between adjacent spiked branches 9, forming a blind-spot-free protective area. This angle design allows the spiked branches 9 to tilt outwards, expanding the protective range while preventing collisions between them, ensuring the effective bird-repelling and anti-climbing functions.

[0025] Furthermore, the spiked branches 9 are fixed at an angle to the poles of the anti-climbing bamboo 7 or the bird-repelling bamboo 8. The spiked branches 9 on the bird-repelling bamboo 8 are angled upwards away from the gas riser 5, while the spiked branches 9 on the anti-climbing bamboo 7 are angled downwards away from the wall, specifically preventing birds from perching above and people from climbing below. The spiked branches 9 have a bamboo shoot-shaped structure, with a root diameter (at the end connected to the pole) of 5-6mm, gradually decreasing to 3-4mm towards the tip, and a length of 30-40mm. The tips are blunt (0.5mm radius), ensuring both bird-repelling and anti-climbing effects while preventing injury to maintenance personnel. After installation, all spiked branches 9 shall not come into contact with the surrounding structure: the minimum distance from the gas riser 5 shall be ≥25mm, the minimum distance from the building wall shall be ≥30mm, and the minimum distance from adjacent pipelines (such as rainwater pipes and air conditioning pipes) shall be ≥30mm. At the same time, they shall not obstruct the valves, pressure gauges and other key components of the gas riser 5, so as to ensure that the operation and maintenance are not interfered with in the later stage, and that they will not cause noise or structural damage due to collision under wind force.

[0026] Furthermore, the surfaces of the anti-climbing thorny bamboo 7, the bird-repelling thorny bamboo 8, and the spiked branches 9 are coated with a dark dye with a thickness of 0.1mm-0.5mm, which is used to warn people around to avoid approaching and accidentally touching them. The surfaces of the anti-climbing thorny bamboo 7 and the bird-repelling thorny bamboo 8 are coated with yellow dye, while the surfaces of the spiked branches 9 on both are coated with red dye.

[0027] The working principle is as follows: First, the wall plate 1 is fixed to the building wall by expansion bolts, providing a stable installation base for the gas riser fixing bracket of the entire high-rise building, ensuring that the bracket as a whole can withstand the weight of the gas riser 5 and external forces in the outdoor environment (such as wind force), and preventing the bracket from shifting or falling off.

[0028] Next, the pipe support plate 2 is welded and fixed to the wall plate 1. As the core load-bearing component of the support, it bears the wall support force transmitted by the wall plate 1 on the one hand, and provides an installation carrier for other functional components such as clamps 4 and screw seats 6 on the other hand, so that each component can be arranged in an orderly manner around the fixing and protection requirements of the gas riser 5.

[0029] Then, the arc-shaped section of the clamp 4 fits against the outer wall of the gas riser 5, and after its two ends pass through the connection holes of the vertical part of the pipe support plate 2, it is tightened by the engagement of the nut 3, which firmly clamps the gas riser 5 to the inner side of the pipe support plate 2, thereby fixing the gas riser 5. At the same time, the small gap reserved between the two can provide a certain displacement space for the pipe when the gas riser 5 expands and contracts due to temperature changes, so as to avoid the pipe from deforming or being damaged due to stress concentration.

[0030] Subsequently, the screw seat 6, as a connecting component, cooperates with the pipe support plate 2, the anti-climbing spiked bamboo 7, and the bird-repelling spiked bamboo 8 respectively. The anti-climbing spiked bamboo 7 is fixed below the pipe support plate 2, and the bird-repelling spiked bamboo 8 is fixed above the pipe support plate 2, so that the two types of spiked bamboo can play a role in different risk scenarios: the anti-climbing spiked bamboo 7 forms a protective barrier below through its own pole and the spread spiked branches 9, preventing people from climbing from the lower floor to the upper floor, avoiding personnel safety accidents and pipe collision damage caused by climbing behavior; the bird-repelling spiked bamboo 8 forms an interference area above the pipe support plate 2 through its own pole and spiked branches 9, preventing birds from staying and nesting near the support, and preventing bird nests and debris from clogging the pipe or bird droppings from corroding the support components.

[0031] Meanwhile, the spiked branches 9 on the anti-climbing bamboo 7 and the bird-repelling bamboo 8 are distributed in an alternating and inclined manner. The spiked branches 9 of the bird-repelling bamboo 8 are inclined upwards away from the gas riser 5, which can more effectively interfere with birds landing from above. The spiked branches 9 of the anti-climbing bamboo 7 are inclined downwards away from the wall, which can specifically prevent people from grabbing and climbing from below. The bamboo shoot-shaped structure and blunt tip treatment of the spiked branches 9 ensure the anti-climbing and bird-repelling effects while avoiding accidental scratches to maintenance personnel or surrounding objects.

[0032] Finally, when the anti-climbing spiked bamboo 7 or bird-repelling spiked bamboo 8 is damaged (such as broken spiked branches 9 or rusted poles), the damaged spiked bamboo can be removed directly through the threaded connection of the screw seat 6 without disassembling the entire bracket. This allows for quick replacement of individual components, reducing the difficulty and cost of later maintenance and ensuring that the bracket maintains stable protection and fixation functions for a long time.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
