Description

Technical Field

[0001] This utility model belongs to the field of pipe support technology, specifically relating to a large-span lightweight pipe support. Background Technology

[0002] Pipe supports are used in the petrochemical industry to support process pipelines, fire-fighting pipelines, and cable trays. They are typically installed beside workshop columns, with a span matching the column spacing of the frame. Generally, pipe and cable tray spans are around 3 meters, while column spacing is usually over 6 meters. Due to the limited column spacing, longitudinal beams are needed in the middle of the pipe supports to support the pipes and cable trays. For column spacing exceeding 10 meters, large-section steel beams or trusses are required to connect the pipe supports. This approach has the following disadvantages: 1. High steel consumption, uneconomical; 2. Large site space occupation, affecting the opening of doors and windows and pipeline layout; 3. If there are few pipelines, the pipelines and large-section steel structures look out of place, affecting aesthetics. Therefore, the design of a large-span lightweight pipe support aims to save costs and reduce space occupation as much as possible while ensuring quality. Utility Model Content

[0003] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0004] A large-span lightweight pipe support includes: support bases, support longitudinal beams, rigid tie rods, support lower struts, and support web members. The support bases are located at both ends of the support and connected to structural columns via embedded parts, serving to support the support longitudinal beams. The upper part of each support base is equipped with pulleys and pipe fixing clamps. The support longitudinal beams connect two support bases, transferring pipe loads to the support bases. The rigid tie rods are located below the support longitudinal beams, connecting the support lower struts to the support bases, and are used to bear the axial tensile force generated by the deformation of the support longitudinal beams. The support lower struts are located below the support longitudinal beams, converting the deformation of the support longitudinal beams into axial force in the rigid tie rods. The support web members are located between the support longitudinal beams, supporting the pipes and transferring loads to the support longitudinal beams.

[0005] Furthermore, the support also includes diagonal braces and a support beam. The diagonal braces are welded between the embedded part and the support beam to transfer vertical loads to the structural column. The upper part of the support beam is fixed with pulleys and pipe fixing clamps.

[0006] Furthermore, the pulleys are made of rubber, have internal bearings, and are installed on the support beam in an adjustable manner.

[0007] Furthermore, the pipe fixing clamps are fixed to the support beam by double nuts, and the number can be adjusted according to the pipe layout requirements.

[0008] Furthermore, the rigid tie rod is connected to the support bracket and the lower support rod of the support bracket by bolts anchored at both ends, and the bolts are used to adjust the tension of the rigid tie rod.

[0009] Furthermore, the longitudinal beams, lower support rods, and web members of the support are all made of small-section lightweight steel, and the cross-sectional height of the longitudinal beams is no more than 120mm.

[0010] Furthermore, the spacing and number of the support web members can be adjusted according to the pipe span and load requirements.

[0011] Furthermore, the number and position of the lower support rods of the bracket are configured according to the deformation of the longitudinal beam of the bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a large-span lightweight pipe support. Through the reasonable configuration of the support base, support longitudinal beam, rigid tie rod, support lower support rod and support web rod, this utility model forms a stable support system, which converts the deflection deformation at the mid-span position into axial force, which is borne by the rigid tie rod, thus significantly improving the load-bearing capacity of the support.

[0014] 2. This utility model provides a large-span lightweight pipe support. The large-span lightweight pipe support used in this application is made of small-section lightweight steel, which has the characteristics of supporting a large span, saving materials, saving space, and being aesthetically pleasing. It significantly reduces material usage and manufacturing costs. At the same time, the use of lightweight steel reduces the self-weight of the support while ensuring strength, which is conducive to the lightweight design of the overall structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1 to 5 As shown, this utility model provides a large-span lightweight pipe support, comprising the following components: a support base 1, disposed at both ends of the support, for supporting the longitudinal beams 2 of the support, and welded and fixed to the structural column by pre-embedded parts 101. The support base 1 includes a diagonal brace 102 and a support beam 103. The diagonal brace 102 is made of angle steel welded between the embedded parts 101 and the support beam 103, with an inclination angle of 45° to 60°, for transferring the vertical load of the pipe to the structural column.

[0024] The support beam 103 is made of 80mm×80mm square steel tubing, with pulleys 105 and pipe fixing clamps 104 mounted on its upper part. The pulleys 105 are made of rubber and contain 6200-type deep groove ball bearings. Their number can be adjusted with bolts to accommodate different pipe installation requirements. The pipe fixing clamps 104 are fixed to the support beam 103 with double nuts, and their number can be adjusted according to the pipe layout.

[0025] The longitudinal beam 2 of the support is attached at both ends to the pulleys 105 of the support beam 103, and is used to connect the two support supports 1 and transfer the mid-span load of the pipeline. The longitudinal beam 2 of the support is made of H-beam steel with a cross section of 100mm×60mm×3mm and a cross section height of 100mm, which meets the requirements of lightweight steel.

[0026] The rigid tie rod 3 connects the support beam 103 of the support bracket 1 to the lower support rod 4 of the support bracket 1 via M20 high-strength bolts 301 anchored at both ends. A preload can be applied to the tie rod by adjusting the nuts of the bolts 301 to counteract the deformation of the longitudinal beam 2 of the support bracket. The rigid tie rod 3 is made of φ20mm round steel.

[0027] The lower support struts 4 are arranged in three sets every 6m span, located below the longitudinal beams 2 of the support, forming a triangular truss structure with the longitudinal beams. Their number is dynamically adjusted according to the deformation of the longitudinal beams, and is used to convert the deflection of the longitudinal beams into the axial force of the rigid tie rods 3; the lower support struts 4 are made of 80mm×40mm rectangular steel pipes.

[0028] The web members 5 of the support structure are welded between the longitudinal beams 2 of the support structure at 1.5m intervals to form a grid-like support structure, which is used to directly support the tunnel and transfer the load to the longitudinal beams. The spacing can be adjusted according to the span and load requirements; the web members 5 of the support structure are made of φ16mm round steel.

[0029] Installation steps of this utility model:

[0030] Embedded parts 101 are installed on the structural column. After the concrete strength reaches the standard, the support bracket 1 is welded. The longitudinal beam 2 of the support is installed on the pulley 105 of the support crossbeam 103, and the web member 5 of the support is welded. The lower support rod 4 of the support is connected to the rigid tie rod 3. Pre-tightening force is applied by adjusting bolt 301 to make the longitudinal beam 2 of the support arch by 10mm to counteract the deflection. After the pipe is placed on the pulley 105 and slid into place, the position is locked by the pipe fixing clamp 104.

[0031] During construction, first install the support bracket 1 and weld it to the embedded part 101. After installing the support bracket 1, install the longitudinal beam 2 and weld both ends of the longitudinal beam 2 to the support bracket 1. Weld the web members 5 of the support bracket to the longitudinal beam 2. The spacing and number of the web members 5 can be adjusted according to the required span of the pipeline. After installing the support bracket 1, the longitudinal beam 2, and the web members 5, install the rigid tie rod 3. One end of the rigid tie rod 3 is anchored to the support bracket 1, and the other end is anchored to the lower support rod 4 of the support. The tension of the tie rod is adjusted using bolts anchored at both ends.

[0032] In use, the pipe is placed on the upper part of the support, and the pipe load is directly borne by the support support 1 and the web member 5. After bearing the pipe load, the web member 5 transfers the load to the longitudinal beam 2 of the support. At this time, the longitudinal beam 2 will have a certain bending deformation due to its large span. The bending deformation is transferred to the lower support rod 4 of the support. At this time, the bolt 301 at the lower support rod 4 and the support support 1 is rotated to reduce the length of the rigid tie rod 3 for adjustment, so that the rigid tie rod 3 is fully tensioned. After the rigid tie rod 3 is adjusted, the lower support rod 4 of the support moves upward, which will offset the bending deformation of the longitudinal beam 2 of the support (the axial force Fn generated by the rigid tie rod 3 forms a resultant force Fa to offset the load Fb generated by the bending deformation of the longitudinal beam 2 of the support).

[0033] Example 2

[0034] When applied to a 15m span, this embodiment is optimized based on Embodiment 1 as follows:

[0035] Support longitudinal beam 2: Select cold-formed thin-walled steel with a cross-section of 120mm×80mm×4mm to meet the cross-section height limit of no more than 120mm.

[0036] Support strut 4: The number of struts has been increased to five, and the spacing has been adjusted to 3m to enhance the control of longitudinal beam deformation.

[0037] Support web member 5: Made of φ20mm round steel, with spacing increased to 1.2m to improve support strength.

[0038] Rigid tie rod 3: Upgraded to φ25mm round steel, and a 30kN preload is applied by a hydraulic tensioner to further suppress deflection.

[0039] Support beam 103: Extended to 2m, with five sets of pulleys 105 and three sets of pipe fixing clamps 104 with shock-absorbing rubber pads to accommodate large-span pipe layouts.

[0040] Example 3

[0041] For high-temperature environments such as high-temperature pipelines in chemical plants, this embodiment makes the following improvements based on Embodiment 1:

[0042] Pulley 105: The material has been changed to heat-resistant silicone rubber, and the bearings are graphite self-lubricating bearings to avoid high-temperature failure. Support longitudinal beam 2: The surface is coated with a 3mm thick fire-retardant coating to improve fire resistance. Pipe fixing clamp 104: Made of stainless steel, with a ceramic fiber insulation layer added to the clamping part to prevent heat conduction. Support lower support rod 4: A 20mm expansion gap is reserved at the connection with the longitudinal beam to accommodate thermal expansion deformation.

[0043] Working principle

[0044] The pipe load is transferred to the longitudinal beam 2 of the support through the web member 5. When the longitudinal beam undergoes deflection deformation due to its large span, the lower support member 4 transfers the deformation to the rigid tie rod 3. The tie rod generates an axial tensile force Fn through the adjusting bolt 301, forming a counterforce Fa to counteract the bending load Fb of the longitudinal beam. The pulley 105 reduces installation friction, and the pipe fixing clamp 104 ensures stability during use.

[0045] Technical effect

[0046] With a span of 10m, the deflection of the longitudinal beams of the support is controlled within L / 400, and the bearing capacity reaches 8kN / m including the medium. The amount of steel used is reduced by 40% compared with traditional trusses, and the space occupation is reduced by 50%, making it suitable for large-span scenarios with sparse pipelines.

[0047] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
