Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire water supply pipeline installation technology, and in particular to a riser mounting bracket for fire water supply pipelines. Background Technology
[0002] Fire water supply pipelines are pipeline systems used to transport fire water in fire protection systems. They are an important part of the fire protection facilities of buildings or places. Fire risers are a type of vertical main pipeline in the fire water supply system of buildings. Their main function is to provide a stable water source and water pressure for fire equipment on each floor in the event of a fire.
[0003] Fire risers are fixed to the building walls using brackets, providing stable support and fixation. Currently, fire risers are typically fixed to the wall using angle steel, with U-bolts straddling both sides of the pipe, the bolts passing through pre-drilled holes in the angle steel, and nuts tightened for complete fixation. Because of its rigid U-shaped structure, the U-bolt cannot undergo significant elastic deformation. When the pipe sways or is impacted by water flow, the U-bolt cannot absorb the external force through bending or expansion, causing stress to concentrate at the contact point between the U-bolt and the fire riser. This localized stress concentration can cause localized deformation of the pipe, such as dents or ellipticization, affecting its mechanical properties and sealing, increasing the risk of pipe rupture and leakage. Furthermore, factors such as thermal expansion and contraction or water flow impact can cause minute displacements and vibrations, accelerating wear at the pipe-bolt contact point and reducing the pipe's service life.
[0004] Therefore, this application provides a riser mounting bracket for fire water supply pipelines to solve the problems mentioned in the background art. Summary of the Invention
[0005] The purpose of this utility model is to provide a riser mounting bracket for fire water supply pipelines, which solves the problems of local deformation of pipelines caused by existing U-bolt fixing, accelerated wear at the contact point between the pipeline and the bolt, and reduced service life of the pipeline.
[0006] To solve the above-mentioned technical problems, this utility model provides a riser mounting bracket for fire-fighting water supply pipelines, including a wall-mounted bracket, a clamp body set on the front side wall of the wall-mounted bracket, fixing rings set at intervals inside the clamp body, and a deformation space formed between the clamp body and the fixing rings. A plurality of spring steel sheets are evenly arranged in the deformation space. The other edge of the spring steel sheet abuts against the annular groove set in the inner side wall of the clamp body, and the other edge of the inner side of the spring steel sheet is fixed to the outer ring wall of the fixing ring. The fixing ring squeezes the spring steel sheet, causing the spring steel sheet to undergo elastic deformation in the deformation space, which is used to buffer the force on the fire-fighting riser and disperse the stress of the fire-fighting riser.
[0007] A further improvement of the present invention is that the spring steel sheet body includes an inner side and an outer side. The portion of the inner side 1 / 5 from the left edge is abutted and fixed to the outer ring wall of the fixing ring, and the portion of the outer side 1 / 3 from the right edge is abutted and fixed to the inner wall of the annular groove.
[0008] A further improvement of this utility model is that the spring steel sheet is arc-shaped, made of spring steel, and the bending direction of the spring steel sheet and the clamp body is the same.
[0009] A further improvement of the present invention is that the clamp body includes two identical, symmetrically arranged semicircular clamps. Ear plates are provided at both ends of the semicircular clamps, and through mounting holes are provided in the ear plates. Mounting bolts are provided in the mounting holes, and the mounting bolts are used to connect the two semicircular clamps together to form a complete clamp structure.
[0010] A further improvement of this utility model is that: one of the semicircular clamps is fixedly connected to the U-shaped angle iron; the inner sidewall of the semicircular clamp is provided with an annular groove, the annular groove and the spring steel sheet have the same thickness, and the outer side of the spring steel sheet is fixed to the inner wall of the annular groove at 1 / 3 of the distance from the right edge.
[0011] A further improvement of the present invention is that the fixing ring includes four ring pieces with the same structure, each ring piece being a quarter-circle ring piece, and several annular convex strips are evenly arranged on the inner sidewall of the ring piece, with the height of the annular convex strips being 0.1~0.5 mm.
[0012] A further improvement of this utility model is that the inner diameter of the fixing ring is 1-3 mm smaller than the inner diameter of the fire riser.
[0013] A further improvement of this utility model is that a spring steel sheet is connected to the middle of the outer side of each ring piece, and the inner side of the spring steel sheet, 1 / 5 of the distance from the left edge, is abutted and fixed to the middle of the outer side wall of the ring piece.
[0014] A further improvement of this utility model is that the width of the deformation space is 5-8 mm.
[0015] A further improvement of the present invention is that the wall mounting bracket includes a mounting plate, expansion bolts are provided on both sides of the mounting plate body, the expansion bolts are used to fix the mounting plate to the wall, and a U-shaped angle iron is provided on the outer wall of the mounting plate body, and a clamp body is fixed on the outer wall of the U-shaped angle iron.
[0016] By adopting the above technical solution, this utility model has the following beneficial effects:
[0017] 1. This utility model provides a riser mounting bracket for fire-fighting water supply pipelines. The riser mounting bracket sets a deformation space between the clamp body and the fixing ring, and evenly arranges arc-shaped spring steel sheets in the same bending direction as the clamp body within the space. When the fire riser is subjected to external forces such as water flow impact and thermal expansion and contraction, the fire riser squeezes the fixing ring, and the fixing ring squeezes the spring steel sheets outward. The spring steel sheets can undergo elastic deformation within the deformation space, thereby buffering the shaking and impact of the pipeline, effectively reducing stress concentration, avoiding deformation of the pipeline due to excessive local stress (such as dents or ellipticization), reducing the risk of pipeline rupture and leakage, and effectively protecting the mechanical properties and sealing of the pipeline.
[0018] 2. This utility model provides a riser mounting bracket for fire-fighting water supply pipelines. The riser mounting bracket is equipped with spring steel plates. The spring steel plates are made of spring steel, which has good elasticity and durability. They can effectively play a buffering and stress-dispersing role for a long time. The buffering effect of the spring steel plates can reduce the wear caused by the relative movement between the pipeline and the riser mounting bracket when the pipeline undergoes minor displacement and vibration during use. Compared with the traditional U-bolt fixing method, this mounting bracket extends the service life of the fire-fighting riser, reduces the frequency of maintenance and replacement due to pipeline wear, and lowers maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] The present invention will be further explained below with reference to specific embodiments.
[0035] like Figures 1-10 As shown in the figure, this embodiment provides a fire-fighting water supply pipeline riser mounting bracket, including a wall-mounted bracket 1, a clamp body 2 set on the front side wall of the wall-mounted bracket 1, and fixing rings 3 set at intervals inside the clamp body 2. The clamp body 2 and the fixing rings 3 enclose a deformation space 4, the width of which is 5-8 mm. Several spring steel sheets 5 are evenly arranged in the deformation space 4. The spring steel sheets 5 are made of spring steel, which has good elasticity and durability and can effectively play a buffering and stress-dispersing role for a long time. One edge of the spring steel sheet 5 abuts against the annular groove 25 set in the inner side wall of the clamp body 2, and the other edge of the inner side 51 of the spring steel sheet 5 is fixed to the outer ring wall of the fixing ring 3. The fixing ring 3 squeezes the spring steel sheet 5, causing the spring steel sheet 5 to undergo elastic deformation in the deformation space 4, which is used to buffer the force on the fire-fighting riser and disperse the stress of the fire-fighting riser. This riser mounting bracket creates a deformation space 4 between the clamp body 2 and the fixing ring 3, and evenly arranges arc-shaped spring steel sheets 5 in the space, which are in the same bending direction as the clamp body 2. When the fire riser is subjected to external forces such as water flow impact and thermal expansion and contraction, the fire riser squeezes the fixing ring 3, and the fixing ring squeezes the spring steel sheets 5 outward, allowing the spring steel sheets 5 to undergo elastic deformation within the deformation space. This buffers the shaking and impact of the pipeline, effectively reduces stress concentration, avoids deformation of the pipeline due to excessive local stress, reduces the risk of pipeline rupture and leakage, and effectively protects the mechanical properties and sealing of the pipeline.
[0036] like Figures 1-3 As shown, in this embodiment, the wall mounting bracket 1 includes a mounting plate 11. Expansion bolts 12 are provided on both sides of the mounting plate 11 body. The expansion bolts 12 are used to fix the mounting plate 11 to the wall. The mounting plate 11 is fixed to the wall by the expansion bolts 12, which can provide a stable foundation for the entire fire riser installation bracket. A U-shaped angle iron 13 is provided on the outer wall of the mounting plate 11 body. The clamp body 2 is fixed on the outer wall of the U-shaped angle iron 13, which provides direct support for the clamp body 2. It can withstand the weight of the pipe and various forces transmitted by the clamp body 2 and effectively transmit these forces to the mounting plate 11.
[0037] like Figures 3-6 as well as Figure 8In this embodiment, the clamp body 2 includes two identical, symmetrically arranged semicircular clamps 21. Ear plates 22 are provided at both ends of the semicircular clamps 21, and through mounting holes 23 are provided in the ear plates 22. Mounting bolts 24 are installed in the mounting holes 23, and the mounting bolts 24 are used to connect the two semicircular clamps 21 together to form a complete clamp structure. One of the semicircular clamps 21 is fixedly connected to a U-shaped angle iron 13. The inner sidewalls of the semicircular clamps 21 are provided with annular grooves 25. The annular grooves 25 and the spring steel sheet 5 have the same thickness. The outer side 52 of the spring steel sheet 5, one-third of the way from its right edge, abuts against and is fixed to the inner wall of the annular groove 25. The annular groove 25 is located on the inner sidewall of the clamp body 2 and is used to accommodate the right edge portion of the spring steel sheet 5.
[0038] like Figure 4 , Figure 5 , Figure 7 As shown in this embodiment, the fixing ring 3 includes four identical ring pieces 31, each ring piece 31 being a quarter-circle ring piece. Several annular protrusions 32 are evenly arranged on the inner wall of each ring piece 31. The height of the annular protrusions 32 is 0.1~0.5 mm. These small protrusions increase the friction between the fixing ring 3 and the outer wall of the fire riser, increasing the clamping effect on the riser. The inner diameter of the fixing ring 3 is 1~3 mm smaller than the inner diameter of the fire riser. A spring steel sheet 5 is connected to the outer center of each ring piece 31. The inner side 51 of the spring steel sheet 5, located 1 / 5 of the way from the left edge, abuts and is fixed to the center of the outer wall of the ring piece 31.
[0039] like Figures 7-10 As shown, in this embodiment, the spring steel sheet 5 body includes an inner side 51 and an outer side 52. The inner side 51 refers to the side of the spring steel sheet 5 facing the fixing ring 3, and the outer side 52 is the side facing the clamp body 2. The portion of the inner side 51 from the left edge 1 / 5 is abutted and fixed to the outer ring wall of the fixing ring 3, and the portion of the outer side 52 from the right edge 1 / 3 is abutted and fixed to the inner wall of the annular groove 25. The spring steel sheet 5 is made of spring steel and is arc-shaped. The spring steel sheet 5 and the clamp body 2 bend in the same direction. The arc-shaped structure of the spring steel sheet 5 allows it to return to its original shape using its elasticity after being deformed by force.
[0040] This utility model also provides a working principle for a fire-fighting water supply pipeline riser mounting bracket: In use, the operator first fixes the wall-mounted bracket 1 to the installation position on the wall, and firmly anchors the fixing plate 11 to the wall using expansion bolts 12, providing a stable foundation for the entire mounting bracket. Next, the fire riser is placed into the semi-circular clamp 21 connected to the wall-mounted bracket 1, and then the two semi-circular clamps 21 are connected into a complete clamp using bolts 24, so that the fire riser is tightly fixed inside the clamp body 2, ensuring its stable installation position. At this time, the ring plate 31 of the fixing ring 3 tightly fits against the outer wall of the fire riser. Since the inner diameter of the fixing ring 3 is 1-3 mm smaller than the inner diameter of the fire riser, the spring steel plate 5 is compressed and deformed in the deformation space 4, reducing the gap in the deformation space 4. After the spring steel plate 5 deforms, more of the left side of the spring steel plate 5 is fitted and engaged with the concave... Inside the groove 25, the compressed spring steel sheet 5 generates a reaction force. This reaction force acts evenly on the ring plate 31 in the fixing ring 3, increasing the effect of the ring plate 31 of the fixing ring 3 in clamping the fire riser. The width of the deformation space 4 is 5~8 mm, which is greater than the 1~3 mm deformation of the fire riser pressing against the fixing ring 3. Therefore, when the fire riser is subjected to external forces such as water flow impact and thermal expansion and contraction, the spring steel sheet 5 still has a certain deformation margin in the deformation space 4. The elasticity of the spring steel sheet 5 can effectively buffer these external forces, disperse stress, reduce the risk of fatigue damage to the pipeline, reduce wear caused by relative movement between the fire riser and the riser mounting bracket, and improve the service life of the pipeline. When the fire riser is not subjected to external factors such as water flow impact and thermal expansion and contraction, the spring steel sheet 5 can spring back to the initial clamping state of the fire riser.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
