Description

Technical Field

[0001] This utility model relates to the field of fixing devices, and in particular to a fire-fighting pipeline fixing device. Background Technology

[0002] A fire hydrant system is a facility that provides water for fire fighting in a building. It connects water sources to various fire-fighting facilities, such as fire hydrants and sprinkler heads, through a pipe network. Since fire hydrants are usually laid on the ceiling of a room, appropriate fixing devices are needed to secure them.

[0003] Existing fire protection pipe fixing devices typically use hangers or steel brackets for fixing during use. However, regardless of whether hangers or steel brackets are used to fix fire protection pipes, the stress points of the support are relatively concentrated. This makes the fire protection pipes prone to dislocation and loosening during earthquakes due to vibration, which can lead to a significant increase in stress at the stress points and create safety hazards.

[0004] Therefore, in response to the aforementioned safety hazard caused by the significant increase in stress at stress points in fire-fighting pipelines during earthquakes, leading to dislocation and loosening, a fire-fighting pipeline fixing device can be designed. By adding multiple stress points to the fixing device, the stress of the fixing device can be distributed among multiple points during an earthquake, thereby solving the above problem. Utility Model Content

[0005] To overcome the limitations of existing fire-fighting pipeline fixing devices, which typically use hangers or steel brackets for fixing during use, the stress points of the support are relatively concentrated when fixing fire-fighting pipelines. This makes it easy for the stress points to increase significantly during earthquakes, leading to dislocation and loosening, which can cause safety hazards.

[0006] The technical solution of this utility model is as follows: a fire-fighting pipeline fixing device, including a first channel steel and a second channel steel, a load-bearing angle steel, a suspension angle steel and a semi-circular pipe support; the opposite surfaces of the first channel steel and the second channel steel are provided with installation grooves, the two ends and the middle section between the first channel steel and the second channel steel are provided with load-bearing angle steel, the two ends of the load-bearing angle steel are provided with notches below, the two ends of the load-bearing angle steel extend into the interior of the installation groove, two sets of suspension angle steel are symmetrically arranged above the middle section of the load-bearing angle steel, and half-circular pipe supports are fixedly installed on both sides of the two sets of suspension angle steel.

[0007] Preferably, this application combines a first channel steel, a second channel steel, a load-bearing angle steel, a suspension angle steel, and a semi-circular pipe support. In the event of an earthquake, the semi-circular pipe support supports and fixes the fire-fighting pipe, the load-bearing angle steel disperses and transmits the stress generated by the vibration and the stress of the fire-fighting pipe itself, the first channel steel and the second channel steel disperse the transmitted stress to the side walls of the room, and the suspension angle steel suspends the middle section of the load-bearing angle steel and disperses the transmitted stress to the top of the room.

[0008] Preferably, L-shaped lugs are fixedly installed on the middle section and both ends of the upper end face of the first channel steel and the second channel steel. The L-shaped lugs include side plates, and the lower end of the side plates is provided with a bottom plate. Two sets of primary connection holes are symmetrically opened at both ends and the middle section of the bottom of the mounting groove. The primary connection holes penetrate the first channel steel and the second channel steel.

[0009] Preferably, the base plate of the L-shaped hook has two sets of secondary connection holes corresponding to the primary connection holes, and the side plate surface of the L-shaped hook has three sets of primary mounting holes in a triangular pattern.

[0010] As a preferred embodiment, the load-bearing angle steel has two sets of tertiary connection holes corresponding to the primary connection holes symmetrically opened at both ends. A primary nut is welded to the upper end of the tertiary connection hole. Triangular plates are welded to both the upper and lower ends of the suspension angle steel. A suspension hole is opened in the center of the triangular plate. Two sets of primary fixing holes corresponding to the suspension hole are symmetrically opened in the middle section of the load-bearing angle steel. A secondary nut is welded to the lower end of the primary fixing hole. Two sets of secondary mounting holes are symmetrically opened on the upper surface of the suspension angle steel.

[0011] As a preferred embodiment, the lower end of the half-arc tube support is symmetrically provided with two sets of support legs in a figure-eight shape. The ends of the two sets of support legs away from the half-arc tube support are provided with fixing plates. The surface of the fixing plates is provided with three sets of secondary fixing holes in a triangular pattern. The three sets of secondary fixing holes penetrate the fixing plates and the load-bearing angle steel.

[0012] Preferably, two sets of quarter-arc blocks are symmetrically arranged above the half-arc tube support. Both ends of the half-arc tube support are provided with movable connecting sleeves. One end of the two sets of quarter-arc blocks is movably connected to both ends of the half-arc tube support through the movable connecting sleeves. The other end of the two sets of quarter-arc blocks is provided with a locking block. The surface of the locking block is symmetrically provided with two sets of locking holes.

[0013] Preferably, rubber pads are fitted at the joints of the first channel steel, the second channel steel, the load-bearing angle steel, the suspension angle steel and the semi-circular pipe support.

[0014] The beneficial effects of this utility model are as follows: Compared with the fixing devices currently on the market, when an earthquake occurs, the stress on the fire-fighting pipes is easily increased due to vibration, leading to dislocation and loosening, which poses a safety hazard. This application combines a first channel steel, a second channel steel, a load-bearing angle steel, a suspension angle steel, and a semi-circular pipe support. In the event of an earthquake, the semi-circular pipe support can support and fix the fire-fighting pipe, preventing it from shaking significantly and increasing unnecessary stress during vibration. The load-bearing angle steel bears the weight of the fire-fighting pipe and distributes the stress generated by the vibration and the stress of the fire-fighting pipe itself to the first channel steel, the second channel steel, and the suspension angle steel. The first and second channel steels are connected to the walls on both sides of the room through L-shaped lugs. The first and second channel steels distribute the transmitted stress to the walls on both sides of the room through multiple connection points, improving the seismic performance of the fixing device. The suspension angle steel suspends the middle section of the load-bearing angle steel, providing a certain degree of support for the load-bearing angle steel, while also distributing some stress to the top wall of the room, further improving the seismic performance of the fixing device.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment: a fire-fighting pipe fixing device, including a first channel steel and a second channel steel 2, a load-bearing angle steel 4, a suspension angle steel 5, and a semi-circular pipe support; the opposite surfaces of the first channel steel 1 and the second channel steel 2 are provided with installation grooves 3, the two ends and the middle section between the first channel steel 1 and the second channel steel 2 are provided with load-bearing angle steel 4, the lower ends of the two ends of the load-bearing angle steel 4 are provided with notches, the two ends of the load-bearing angle steel 4 extend into the interior of the installation groove 3, two sets of suspension angle steel 5 are symmetrically arranged above the middle section of the load-bearing angle steel 4, and half-circular pipe supports 6 are fixedly installed on both sides of the two sets of suspension angle steel 5.

[0023] Please see Figures 2-3 In this embodiment, L-shaped lugs 9 are fixedly installed on the upper end face of the first channel steel 1 and the second channel steel 2 at the middle and both ends. The L-shaped lugs 9 include side plates, and the lower end of the side plates is provided with a bottom plate. Two sets of primary connection holes 8 are symmetrically opened at both ends and the middle of the bottom of the mounting groove 3. The primary connection holes 8 penetrate the first channel steel 1 and the second channel steel 2. The bottom plate of the L-shaped lugs 9 is symmetrically opened with two sets of secondary connection holes 11 corresponding to the primary connection holes 8. The side plate surface of the L-shaped lugs 9 is provided with three sets of primary mounting holes 10 in a triangular pattern. By combining the primary connection holes 8 with the secondary connection holes 11, the operator can pass long bolts through the primary connection holes 8. The long bolt is screwed through the first channel steel 1 or the second channel steel 2, and then screwed into the second-level connection hole 11 from the first-level connection hole 8 and locked with bolts, so that the L-shaped hanging ear 9 is fixedly installed on the first channel steel 1 and the second channel steel 2. Since the long bolt passes through the first channel steel 1 or the second channel steel 2, the deformation of the installation groove 3 caused by vibration can be reduced after the long bolt is locked by the nut. Through the combination of three sets of first-level installation holes 10, the workers can drive the expansion bolts into the first-level installation holes 10. Through the triangular structure of the three sets of first-level installation holes 10, the connection strength between the first channel steel 1, the second channel steel 2 and the wall is improved and strengthened, which can effectively prevent dislocation and loosening.

[0024] Please see Figures 2-3In this embodiment, two sets of tertiary connection holes 13 corresponding to primary connection holes 8 are symmetrically opened at both ends of the load-bearing angle steel 4. A primary nut 14 is welded to the upper end of the tertiary connection hole 13. Triangular plates 16 are welded to both the upper and lower ends of the suspension angle iron. A suspension hole 17 is opened in the center of the triangular plate 16. Two sets of primary fixing holes 18 corresponding to the suspension holes 17 are symmetrically opened in the middle section of the load-bearing angle steel 4. A secondary nut 19 is welded to the lower end of the primary fixing hole 18. Two sets of secondary mounting holes 15 are symmetrically opened on the upper surface of the suspension angle iron. Rubber pads 12 are attached to the connection points of the first channel steel 1, the second channel steel 2, the load-bearing angle steel 4, the suspension angle steel 5 and the semi-circular pipe support. The combination of the tertiary connection holes 13 and the primary fixing holes 18 makes the installation... When the long bolt mentioned above is tightened, it can pass through the primary connection hole 8, the tertiary connection hole 13 and the secondary connection hole 11 in sequence. With the long bolt and the primary nut 14 in cooperation, the two ends of the load-bearing angle steel 4 can be prevented from shaking in the mounting groove 3. Through the suspension hole 17, during installation, the workers can drive the expansion bolt into the roof through the upper suspension hole 17 of the suspension angle steel and screw the bolt into the lower suspension hole 17 of the suspension angle steel, which passes through the suspension hole 17 and the secondary nut 19 in sequence for installation. Through the two sets of secondary mounting holes 15, the workers can drive the expansion bolt into the roof beam through the two sets of secondary mounting holes 15 to further distribute the stress. The rubber pad 12 provides a certain degree of buffering to avoid rigid collisions between the components.

[0025] Please see Figures 3-5 In this embodiment, the lower end of the half-arc pipe support 6 is symmetrically provided with two sets of support legs 20 in a figure-eight shape. Each set of support legs 20 has a fixing plate 21 at the end furthest from the half-arc pipe support 6. The surface of the fixing plate 21 has three sets of secondary fixing holes 22 arranged in a triangular pattern. These three sets of secondary fixing holes 22 penetrate the fixing plate 21 and the load-bearing angle steel 4. The combination of these three sets of secondary fixing holes 22 allows workers to securely install the half-arc pipe support 6 onto the load-bearing angle steel 4 using bolts and nuts. Two sets of quarter-arc blocks 7 are symmetrically provided above the half-arc pipe support 6. Both ends of the half-arc pipe support 6 are provided with movable connecting sleeves 23. One end of each of the two sets of quarter-arc blocks 7 is movably connected to both ends of the half-arc pipe support 6 through the movable connecting sleeves 23. The other end of each of the two sets of quarter-arc blocks 7 is provided with a locking block 24. The surface of each locking block 24 is symmetrically provided with two sets of locking holes 25. By combining the two sets of quarter-arc blocks 7, after the worker places the fire pipe on the half-arc pipe support 6, the worker can rotate the two sets of quarter-arc blocks 7 through the movable connecting sleeves 23, and then pass the bolt through the locking hole 25 and lock it with a nut.

[0026] During operation, workers can pass a long bolt through the primary connection hole 8 through the first channel steel 1 or the second channel steel 2, and then screw the long bolt from the primary connection hole 8 into the secondary connection hole 11 and lock it in place with bolts, so that the L-shaped hanging lug 9 is fixedly installed on the first channel steel 1 and the second channel steel 2. Since the long bolt passes through the first channel steel 1 or the second channel steel 2, the deformation of the installation groove 3 caused by vibration can be reduced after the long bolt is locked by the nut.

[0027] Workers can drive expansion bolts into the primary mounting holes 10. The triangular structure of the three sets of primary mounting holes 10 enhances the connection strength between the first channel steel 1, the second channel steel 2 and the wall, effectively preventing dislocation and loosening.

[0028] During installation, workers can drive expansion bolts into the roof through the upper suspension hole 17 of the suspension angle iron, and screw bolts into the lower suspension hole 17 of the suspension angle iron, passing them through the suspension hole 17 and the secondary nut 19 for installation. Through the two sets of secondary mounting holes 15, workers can drive expansion bolts into the roof beam to further distribute the stress. The rubber pad 12 provides a certain degree of buffering to avoid rigid collisions between the components.

[0029] Through the above steps, this application combines the first channel steel 1, the second channel steel 2, the load-bearing angle steel 4, the suspension angle steel 5, and the semi-circular pipe support. This allows the semi-circular pipe support to firmly support and fix the fire-fighting pipe during an earthquake, preventing it from swaying excessively and increasing stress. The load-bearing angle steel 4 bears the weight of the fire-fighting pipe and distributes the stress generated by the vibration, as well as the stress within the fire-fighting pipe itself, to the first channel steel 1, the second channel steel 2, and the suspension angle steel 5. The first channel steel 1 and the second channel steel 2 are connected to the walls on both sides of the room via L-shaped lugs 9. Through multiple connection points, the first channel steel 1 and the second channel steel 2 distribute the transmitted stress to the walls on both sides of the room, improving the seismic performance of the fixing device. The suspension angle steel 5 suspends the middle section of the load-bearing angle steel 4, providing some support and simultaneously distributing some stress to the top wall of the room, further enhancing the seismic performance of the fixing device.
