Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a pipe fixing device for use in prefabricated buildings. Background Technology

[0002] In the traditional process of installing electromechanical systems in integrated pipe shafts of high-rise buildings, the various professional pipe supports are fixed to the partition walls of the pipe shaft, and the support clamps are used to secure the risers. However, the pipe shaft walls in prefabricated buildings use lightweight steel keel partition walls. Due to the special structure and strength limitations of the lightweight steel keel partition walls, the pipe installation inside the pipe shaft cannot be carried out by drilling holes in the wall and using expansion bolts to fix the pipe supports as in the traditional method. Otherwise, it will easily lead to problems such as loose supports, violent pipe shaking, support detachment, partition wall panel breakage, and pipe deformation and sinking, which will greatly affect the use effect and pose serious quality and safety hazards.

[0003] Faced with increasingly tight construction schedules, simply strengthening supervision and management of work teams to properly fix the pipes in the integrated pipe wells is insufficient to fully guarantee that the large number of pipes on site will meet quality and safety requirements. Therefore, there is an urgent need to adopt an effective and rapid integrated pipe well fixing device to improve the efficiency of pipe installation and fixing, while effectively preventing damage to the pipe well walls and pipes and other quality and safety hazards caused by improper fixing. Summary of the Invention

[0004] Therefore, it is necessary to provide a pipe fixing device for prefabricated buildings that can quickly fix pipes and ensure the quality and safety of the building, in order to address the above problems.

[0005] A pipe fixing device for prefabricated buildings includes a support assembly, a connecting assembly, and fixing elements. The support assembly includes a first support rod, a second support rod, and a third support rod, one end of each of the three support rods being fixedly mounted to the building's base. The connecting assembly includes a first connecting rod and a second connecting rod, which are not collinear and are connected at a first connection point. The first connecting rod and the second connecting rod are fixedly connected to the first support rod through the first connection point. The end of the first connecting rod furthest from the first connection point is fixedly connected to the second support rod, and the end of the second connecting rod furthest from the first connection point is fixedly connected to the third support rod. Multiple fixing elements are disposed on the first connecting rod and the second connecting rod and are configured to fix the pipe.

[0006] By adopting the above technical solution, the pipe is fixed in the fastener on the connecting assembly, and the connecting assembly is fixed to the building floor by the support assembly, so that the pipe can be fixed without relying on the building wall. The first connecting rod and the second connecting rod are connected non-collinearly, so that when the first connecting rod and the second connecting rod are deflected by circumferential tension, they can not only be supported by the support assembly, but also provide mutual support within the connecting assembly to maintain the overall stability of the connecting assembly.

[0007] In one embodiment, the fastener is disposed on the side of the first connecting rod near the building wall, the side of the first connecting rod near the building wall is designated as the first placement area, and the side of the first connecting rod away from the building wall is designated as the maintenance area.

[0008] By adopting the above technical solution, the pipeline is fixed to the first installation area near the building wall of the first connecting rod, which can effectively utilize the space inside the building. At the same time, the side away from the building wall is set as the maintenance area to provide sufficient space for maintenance operations.

[0009] In one embodiment, the fastener is disposed on the side of the second connecting rod near the building wall, and the side of the second connecting rod near the building wall is designated as the second placement area.

[0010] By adopting the above technical solution, a separate second placement area is formed on the second connecting rod to separate the pipe fixed on the second placement area from the pipe on the first placement area, so as to meet the requirement that liquid pipes and gas pipes need to be isolated to maintain safety.

[0011] In one embodiment, the first connecting rod and the second connecting rod are arranged perpendicularly.

[0012] By adopting the above technical solution, the first connecting rod and the second connecting rod are arranged perpendicularly to each other, which facilitates connection and installation, reduces the processing cost and processing time when connecting the first connecting rod and the second connecting rod, and thus improves the installation speed of the pipe fixing device.

[0013] In one embodiment, the fasteners include a plurality of fasteners arranged on the first connecting rod in a direction toward the first connection point in order of decreasing size.

[0014] By adopting the above technical solution, the pipelines can be arranged in descending order to the first connection point, thereby alleviating the problem of space congestion at the connection point and improving the space utilization rate within the building.

[0015] In one embodiment, the connecting assembly further includes an adapter disposed at the first connection point, the adapter being fixedly connected to the first connecting rod, the second connecting rod, and the first support rod.

[0016] By adopting the above technical solution, the adapter is set on the first connection point, which can improve the connection strength between the first connecting rod, the second connecting rod and the first support rod.

[0017] In one embodiment, the first support rod is provided with a plurality of mounting slots, and the adapter is mounted on the first support rod through the mounting slots.

[0018] By adopting the above technical solution, the mounting groove can simultaneously provide a base for installing the adapter, and at the same time, the mounting groove can reduce the weight of the first support rod and improve its stability.

[0019] In one embodiment, the first connecting rod includes multiple first connecting rods, which are connected to the first support rod and the second support rod through the mounting groove.

[0020] By adopting the above technical solution, more fasteners can be installed on multiple first connecting rods, thereby providing more pipe installation positions and increasing the stability of the pipe fixed on the first connecting rods.

[0021] In one embodiment, the plurality of mounting slots are distributed at equal intervals along the axial direction of the first support rod.

[0022] By adopting the above technical solution, the adapter can be freely adjusted in installation position on the first support rod via the mounting slot to adapt to installation requirements under different conditions and improve installation flexibility.

[0023] In one embodiment, the inner wall profile of the mounting groove is configured as a cross shape.

[0024] By adopting the above technical solution, the cross-shaped mounting groove can increase the contact area between the first connecting rod, the second connecting rod and the first support rod, thereby improving the connection strength between the first connecting rod, the second connecting rod and the first support rod.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By adopting the above technical solution, the pipeline is fixed in the fastener on the connecting assembly, and the connecting assembly is fixed to the building floor by the supporting assembly, so that the pipeline can be fixed without relying on the building wall. The first connecting rod and the second connecting rod are connected non-collinearly, so that when the first connecting rod and the second connecting rod are deflected by the circumferential tensile force, they can not only be supported by the supporting assembly, but also provide mutual support within the connecting assembly to maintain the overall stability of the connecting assembly.

[0027] 2. By adopting the above technical solution, the pipeline is fixed to the first installation area near the building wall of the first connecting rod, which can effectively utilize the space inside the building, while setting the side away from the building wall as the maintenance area to provide sufficient space for maintenance operations.

[0028] 3. By adopting the above technical solution, a separate second placement area is formed on the second connecting rod to separate the pipe fixed on the second placement area from the pipe on the first placement area, so as to meet the requirement that liquid pipes and gas pipes need to be isolated to maintain safety.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] Please see Figure 1 , Figure 1This diagram illustrates a first-view structural schematic of a pipe fixing device according to an embodiment of this application. The pipe fixing device provided in this embodiment includes a support assembly 100, a connecting assembly, and fixing members 300. The support assembly 100 is disposed on the building's base and provides an installation foundation for the connecting assembly. The connecting assembly includes multiple intersecting connecting rods, which form a stable frame structure to improve the overall stability of the pipe fixing device. Each connecting rod is equipped with a fixing member 300 for fixing different pipes. By using the support assembly 100 disposed on the building's base and the interconnected connecting rods to provide support and fix the pipes, this method replaces the method of fixing pipes with supports on building walls, avoiding the safety hazards caused by damage to the walls of prefabricated buildings caused by installing supports on the walls.

[0035] The support assembly 100 includes a first support rod 110, a second support rod 120, and a third support rod 130. One end of each of the first, second, and third support rods is fixed to the building's base to provide support. Specifically, the positions of the first, second, and third support rods define the location of the connecting assembly, thereby indirectly defining the location of the pipe. The projections of the centers of the first, second, and third support rods on the horizontal plane are not collinear, ensuring that the connecting assembly mounted on the first, second, second, and third support rods forms a stable triangular structure, improving the stability of the pipe fixing device.

[0036] The pipe fixing device is installed in the integrated pipe shaft of the prefabricated building. The space inside the integrated pipe shaft is relatively narrow. Therefore, the first support rod 110, the second support rod 120 and the third support rod 130 are all set close to the building wall. This ensures that enough space is reserved between the support rod and the wall for fixing the pipe, while also providing sufficient maintenance space for the maintenance area on the side of the support rod away from the wall.

[0037] Please refer to the following: Figure 2 , Figure 2 The diagram shows a second-view structural schematic of a pipe fixing device according to an embodiment of this application. A fixing base 112 is provided on one end of the first support rod 110 that connects to the building floor. The fixing base 112 is used to fix the first support rod 110 to the building floor. Specifically, the fixing base 112 is a rectangular structure with multiple screw holes symmetrically arranged along its edges. After drilling holes in the floor decking inside the integrated pipe shaft and inserting expansion bolts, the fixing base 112 is fixed to the floor decking through threaded connections, thereby fixing the first support rod 110 to the building floor.

[0038] Specifically, in this embodiment, when installing the fixed base 112, it is necessary to first use a tape measure to measure and locate the position on-site, mark the precise position of the expansion bolts, and use a φ10 drill bit to drill holes in the floor decking. The hole depth should not exceed 1 / 2 of the floor decking thickness, and the hole depth is usually no more than 50mm. Align the screw holes on the fixed base 112 with the holes in the floor decking, and use a laser level to check and level them. Finally, use M8 or M10 expansion bolts to firmly fix the fixed base 112 to the floor decking, ensuring the tightness of the fixed base 112 while preventing cracking and leakage in the floor decking structure.

[0039] In some other embodiments, since the building's bottom surface is not suitable for drilling operations, the fixed base 112 is a cast concrete circular pier, and the first support rod 110 is set at the center of the concrete circular pier to fix the first support rod 110 to the building's bottom surface.

[0040] It is understood that the first support rod 110, the second support rod 120 and the third support rod 130 can all be fixedly connected to the bottom surface of the building in the same way, and those skilled in the art can select a suitable connection method to fix the first support rod 110, the second support rod 120 and the third support rod 130 to the bottom surface of the building according to the specific material and structure of the building.

[0041] The first support rod 110 is provided with a plurality of mounting slots 111, which provide a mounting base for the connecting components. Simultaneously, the mounting slots 111 reduce the weight of the first support rod 110 itself, thereby achieving lightweighting of the pipe fixing device and improving its stability. Specifically, the multiple mounting slots 111 are evenly distributed along the axial direction of the first support rod 110, providing multiple mounting positions for the connecting components on the first support rod 110, allowing the installation height of the connecting components to be adjusted according to specific pipe layout requirements.

[0042] In a specific embodiment, the inner wall contour of the mounting groove 111 is set as a strip hole, and the relatively short side of the strip hole is set as an arc, so as to facilitate the installation of the connecting components and reduce the processing cost of the mounting groove 111.

[0043] In some other embodiments, the inner wall profile of the mounting groove 111 is set to a cross shape to increase the contact area when the connecting component is connected to the mounting groove 111, thereby increasing the connection strength between the first support rod 110 and the connecting component.

[0044] To enable rapid pipeline installation, the first support rod 110 is pre-processed before installation in the integrated pipe well. Specifically, in this embodiment, the first support rod 110 is a galvanized C-shaped channel steel. The first support rod 110 undergoes pre-custom measurement, cutting, edge grinding, and corrosion protection, and is assembled using bolts and right-angle connectors. This allows the bottom of the first support rod 110 to be locked together with the fixed base 112, forming a three-dimensional spliced ​​structure from line to surface to volume. Finally, it is transported to the installation area, thereby reducing on-site construction time and increasing the construction speed of the pipeline fixing device.

[0045] The connecting assembly includes a first connecting rod 210 and a second connecting rod 220. The first connecting rod 210 is connected to the first support rod 110 and the second support rod 120, and the second connecting rod 220 is connected to the first support rod 110 and the third support rod 130. The first connecting rod 210 and the second connecting rod 220 intersect at the first connection point 230, so that the first connecting rod 210 and the second connecting rod 220 form a whole and provide mutual support, thereby improving the overall stability of the connecting assembly.

[0046] Specifically, the first connecting rod 210 is provided with multiple fasteners 300 for fixing the pipes. The fasteners 300 are located on the side of the first connecting rod 210 closest to the building wall and form a first installation area, in which the pipes on the first connecting rod 210 are correspondingly installed. The side of the first connecting rod 210 away from the building wall is an empty maintenance area, providing sufficient space for pipe maintenance.

[0047] In a specific embodiment, the first connecting rod 210 comprises multiple rods, which are arranged parallel to each other between the first support rod 110 and the second support rod 120 to jointly fix the pipeline. Sufficient space needs to be reserved between the multiple first connecting rods 210 to provide installation and maintenance space for valves, fittings, and instruments.

[0048] In other embodiments, depending on the structural type or floor height restrictions of the integrated pipe well in different projects, the pipe fixing device is set as a split-type fixed pipe or an integrated through-type fixed pipe. Therefore, those skilled in the art can adjust the number and setting position of the first connecting rod 210 in the vertical direction as needed to flexibly adapt to various building carriers.

[0049] The second connecting rod 220 is also equipped with multiple fasteners 300 for fixing the pipes. The fasteners 300 are located on the side of the second connecting rod 220 closest to the building wall, forming a second installation area. The pipes on the second connecting rod 220 are correspondingly installed within this second installation area. Since the first connecting rod 210 and the second connecting rod 220 are not collinear, the first and second installation areas are staggered. The pipes in the first installation area and the pipes in the second installation area have a large distance between them, reducing interference between them. This allows gas and liquid pipes within the integrated pipe shaft to be installed separately, facilitating the overall pipe layout design.

[0050] Specifically, the first connecting rod 210 and the second connecting rod 220 intersect at the first connection point 230, and are fixedly connected to the first support rod 110 through the first connection point 230. Simultaneously, the first connecting rod 210 is fixedly connected to the second support rod 120, and the second connecting rod 220 is fixedly connected to the third support rod 130, forming connection points. This provides support to the connecting assembly at three connection points, adding a support dimension compared to the traditional method of fixing pipes to the wall, thus improving the pipe's fixation effect. Furthermore, it achieves its fixing function without relying on the wall, avoiding damage to the walls of prefabricated buildings and preventing potential safety hazards.

[0051] Specifically, in this embodiment, the first connecting rod 210 and the second connecting rod 220 are arranged perpendicularly to each other, making the overall connecting assembly T-shaped. The perpendicularly connected first connecting rod 210 and second connecting rod 220 can conform to conventional building shapes and specifications, maximizing the use of space within the integrated pipe shaft. Simultaneously, the perpendicularly connected first connecting rod 210 and second connecting rod 220 reduces connection difficulty and assembly processes, thereby improving the installation efficiency of the pipe fixing device.

[0052] In other embodiments, in order to adapt to the design and layout of integrated manholes and pipelines of different specifications and sizes, the first connecting rod 210 and the second connecting rod 220 are arranged in an L-shape or an X-shape. Those skilled in the art can make adaptive adjustments to the connection method and positional relationship between the first connecting rod 210 and the second connecting rod 220 according to actual needs.

[0053] The connecting assembly also includes an adapter 400, through which the first connecting rod 210 and the second connecting rod 220 are connected. Specifically, the adapter 400 includes a connecting portion that connects to the first connecting rod 210, the second connecting rod 220, and the first support rod 110. The connecting portion is provided with a threaded hole, which corresponds to the mounting groove 111 on the first connecting rod 210, the second connecting rod 220, and the first support rod 110. The adapter 400 is fixedly connected to the first connecting rod 210, the second connecting rod 220, and the first support rod 110 by bolts. In a specific embodiment, the connecting parts on the adapter 400 are arranged perpendicularly to each other to fit the specific structure of the pipe fixing device. When installing the adapter 400 and the first support rod 110, screws are first used to pass through the first support rod 110 and the adapter 400 for temporary fixation. Then, the splicing of the adapter 400 and the first support rod 110 is checked. After confirming that there are no errors, the bolts are tightened to the first support rod 110 with nuts.

[0054] Fixing members 300 are installed on the first connecting rod 210 and the second connecting rod 220 to fix the pipes. Specifically, the distance between each fixing member 300 is determined according to the pipe diameter and function, and multiple fixing members 300 are arranged on the first connecting rod 210 in order of decreasing size, in the direction toward the first connection point 230, thereby alleviating the problem of space congestion at the connection point and improving the space utilization rate within the building.

[0055] Specifically, in this embodiment, the spacing between each fixing member 300 is set to 140mm to 210mm. Preferably, the spacing between the fixing member 300 for fixing the drain pipe and the fixing member 300 for fixing the vent pipe is fixed at 180mm to meet the installation specifications of the finished H-type vent.

[0056] The fastener 300 is a U-shaped clamp with both ends set in the mounting grooves 111 on the first connecting rod 210. The pipe is clamped in the installation space formed by the clamp and the first connecting rod 210. When the pipe is clamped in the installation space, the clamp is locked by adjusting the fasteners on the clamp, and the bolts and nuts on the clamp are adjusted to a tight state to achieve quick connection and fixation between the device and the pipe.

[0057] In specific embodiments, those skilled in the art can select clamps of different sizes according to different pipe types and pipe diameters. A rubber pad is provided on the inner side of the clamp near the pipe to provide a cushioning function.

[0058] The working principle of the pipe fixing device in this embodiment is as follows: the first support rod 110, the second support rod 120, and the third support rod 130 are prefabricated to improve the speed of on-site construction. The support assembly 100 formed by the first support rod 110, the second support rod 120, and the third support rod 130, together with the connecting assembly formed by the first connecting rod 210 and the second connecting rod 220, forms a three-point support structure to improve the stability of the pipe fixing device. Simultaneously, the support assembly 100 is fixed using the building's base surface rather than relying on the building's walls, ensuring the stability of the protective walls in prefabricated buildings and avoiding quality and safety hazards caused by damage to the wall structure. Finally, the first installation area, the second installation area, and the maintenance area formed by the staggered arrangement of the first connecting rod 210 and the second connecting rod 220 can fully utilize the space within the narrow integrated pipe shaft, ensuring the isolation of different types of pipes to meet the pipe design layout requirements, and reserving sufficient maintenance space for repairs.
