Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline installation technology, and in particular to the connection structure of reserved pipe racks inside the workshop. Background Technology
[0002] A workshop is a place in industrial production where product processing, assembly, and inspection are carried out. It is the core execution unit in the enterprise's production process. It is equipped with specific equipment, tools, production lines, and operators, and undertakes the task of transforming raw materials into semi-finished products and finished products. It is a basic component of the industrial manufacturing system. The reserved pipe rack connection structure inside the workshop refers to the pre-set support structure for various types of pipes in the building structure and equipment layout of the industrial workshop. It is a technical measure to ensure the stable and safe operation of the pipeline system through specific connection methods. Its core purpose is to provide a standardized support foundation for future pipeline installation, maintenance, and functional expansion during the construction and renovation phase of the workshop, and to avoid interference with production during later construction.
[0003] A search revealed Chinese Patent Publication No. CN113443569A, which discloses a method for installing pipelines in a workshop. The method includes the following steps: erecting a pipeline assembly platform at the pipeline hoisting location and setting up a rolling conveyor along the pipeline installation direction; sequentially performing pipe-end docking on the pipeline assembly platform to obtain the pipe-end docked pipe; dragging the pipe-end docked pipe onto the rolling conveyor using a traction device, which rotates along the dragging direction of the pipe-end docked pipe, moving it to the installation position under the action of the traction device and the rolling conveyor. This invention solves the problems of low installation efficiency and high cost in traditional pipeline installation techniques due to space constraints and complex segmented pipe-dragging processes. Furthermore, in existing technologies, pipelines require the removal of main beams for subsequent modification and maintenance. In recent years, several workshop projects have encountered issues with reserved pipe rack loads, where process pipelines often cannot be fully specified in the civil engineering design and require advance reservation by the civil engineering team, but the exact location cannot be clearly defined. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a pre-reserved pipe rack connection structure inside the workshop, which aims to improve the existing technology where the main beam needs to be removed when the pipeline needs to be modified and maintained in the future. In recent years, we have encountered many projects with pre-reserved pipe rack loads inside the workshop. Since the process pipelines cannot be fully proposed in the civil engineering design, the civil engineering needs to reserve them in advance, but the location cannot be clearly proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pre-reserved pipe rack connection structure inside the workshop, including multiple frame beams, a beam bottom embedded sleeve two is provided on the left side of the middle outer wall of the middle frame beam one, a beam bottom embedded sleeve one is provided on the right side of the outer wall of the middle frame beam one, a frame column one is provided in the middle of the outer wall of the upper frame beam one, a frame column three is provided in the middle of the outer wall of the lower frame beam one, a frame column two is provided on the right side of the outer wall of the lower frame beam one, a column side embedded part is provided at the top of the frame column three, and a pipe rack crossbeam is provided at the top of the column side embedded part.
[0006] The above technical solution involves multiple main frame structures, forming a three-dimensional support system through the upper frame column one, the lower frame column two, and the lower frame column three. This provides a stable load-bearing foundation for the entire pipe rack connection structure. The embedded parts on the top of the frame column three serve as prefabricated connection nodes, which can be directly fixed to the pipe rack beams. This allows for rapid assembly without the need to temporarily drill holes or damage the structure when installing steel beams later, avoiding secondary damage to the main structure.
[0007] As a further description of the above technical solution:
[0008] Multiple beam bottom embedded parts are equidistantly arranged in the middle of the outer wall of the frame beam one, and a frame longitudinal beam is arranged on the top of the beam bottom embedded parts.
[0009] The above technical solution involves embedding components at equal intervals along the outer wall of the beam, with the components pre-embedded at the bottom of the beam. These components are welded to the main reinforcement of the beam via anchor bars before the concrete beam is poured. The surface of the embedded component is flush with the bottom formwork of the beam. Bolt holes or welded pads are pre-set on the embedded component to form a rigid connection interface with the longitudinal beams of the frame, ensuring that the pipe load is directly transferred to the main reinforcement of the beam through the embedded component, avoiding localized stress concentration.
[0010] As a further description of the above technical solution:
[0011] The bottom of the embedded part at the bottom of the beam is provided with a pipe reserved groove one, and the bottom of the pipe reserved groove one is provided with a pipe reserved groove two.
[0012] The above technical solution allows for the use of two pre-reserved slots: one for smaller diameter pipes or secondary pipes, and the other for larger diameter pipes or main pipes. This facilitates the core function of gravity flow pipe layout. By pre-setting multiple slots, the solution meets the needs of pipes of different heights and diameters for cross-arrangement, while reducing space conflicts during later installation.
[0013] As a further description of the above technical solution:
[0014] The bottom of the pipe reserved groove 2 is provided with a pipe reserved groove 3, and multiple frame beams 2 are fixedly connected at equal intervals inside the embedded parts at the bottom of the beam.
[0015] Through the above technical solution: Pipe reserved groove three serves as the lowest reserved groove at the bottom of the embedded part of the beam, forming a multi-layered pipe arrangement space in the vertical direction with the pipe reserved groove one and reserved groove two above.
[0016] As a further description of the above technical solution:
[0017] The frame beam 1 has a side-embedded sleeve 3 inside, the top of the side-embedded sleeve 3 is provided with a roof panel 1, and the top of the frame longitudinal beam is provided with a roof panel 2.
[0018] Through the above technical solution: the frame longitudinal beams serve as horizontal load-bearing components, supporting the roof slabs at the top, and are fixedly connected to the beams through embedded parts at the bottom, forming a stable structural support system.
[0019] As a further description of the above technical solution:
[0020] A secondary steel beam is installed on the outer side of the crossbeam of the pipe rack, and a beam-side embedded sleeve is installed in the middle of the outer wall of the upper frame beam.
[0021] The above technical solution involves embedding parts at the top of the pipe rack beam and on the side of the column, with pre-set modular connection nodes on the outer side for later installation of steel beams.
[0022] This utility model has the following beneficial effects:
[0023] In this invention, embedded parts are pre-embedded on the side of the column during the construction of the concrete column, and bolt holes or welding interfaces are reserved at the top. Later, the pipe rack beams are directly installed to form vertical pipe support points. The outer side of the pipe rack beams can be connected to steel beams later to adapt to the needs of adjusting the span of the process pipeline. No additional drilling or welding is required to damage the column. This avoids the problem that in the existing technology, when the pipeline needs to be modified and maintained later, the main beam needs to be removed. In recent years, we have encountered many projects in workshops that reserve pipe rack loads. Because the process pipelines cannot be fully specified in the civil engineering design, the civil engineering needs to reserve them in advance, but the location cannot be clearly specified.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: a pre-reserved pipe rack connection structure inside the workshop, including multiple frame beams 1, a beam bottom embedded sleeve 2 8 is provided on the left side of the middle outer wall of the middle frame beam 1, a beam bottom embedded sleeve 3 is provided on the right side of the outer wall of the middle frame beam 1, a frame column 2 is provided in the middle of the outer wall of the upper frame beam 1, a frame column 3 5 is provided in the middle of the outer wall of the lower frame beam 1, a frame column 4 is provided on the right side of the outer wall of the lower frame beam 1, a column side embedded part 6 is provided at the top of the frame column 3 5, a pipe rack crossbeam 10 is provided at the top of the column side embedded part 6, multiple beam bottom embedded parts 7 are equidistantly provided in the middle of the outer wall of the middle frame beam 1, and a frame longitudinal beam 13 is provided at the top of the beam bottom embedded part 7.
[0032] Specifically, multiple components form the main frame structure, creating a three-dimensional support system through the upper frame column 1 (2), the lower frame column 2 (4), and the lower frame column 3 (5). This provides a stable load-bearing foundation for the entire pipe rack connection structure. Embedded parts 6 are installed on the top of frame column 3 (5) as prefabricated connection nodes, allowing direct fixed connection to the pipe rack beams. This eliminates the need for temporary drilling or structural damage during later steel beam installation, enabling rapid assembly and avoiding secondary damage to the main structure. Embedded parts 7 are equidistantly located at the bottom of the beams on the outer wall of frame beam 1 (1) in conjunction with the beams. These are welded to the main reinforcement of the beams via anchor bars before concrete pouring, with the surface of the embedded parts flush with the bottom formwork. Bolt holes or welded pads are pre-installed on the embedded parts to form a rigid connection interface with the frame longitudinal beams 13, ensuring that the pipe load is directly transferred to the main reinforcement of the beams through the embedded parts, avoiding localized stress concentration.
[0033] Reference Figure 1 and Figure 4 The bottom of the embedded part 7 at the bottom of the beam is provided with a pipe reserved groove 15, and the bottom of the pipe reserved groove 15 is provided with a pipe reserved groove 2 16. The upper groove, such as the pipe reserved groove 15, can be used for smaller pipe diameters or secondary pipes, and the lower groove, such as the pipe reserved groove 2 16, can be used for larger pipe diameters or main pipes, which facilitates the layout of gravity flow pipes. The core function is to meet the cross-arrangement requirements of pipes of different heights and diameters by pre-setting multiple groove positions, while reducing the space conflict during later installation. The bottom of the pipe reserved groove 2 16 is provided with a pipe reserved groove 3 17. Multiple frame beams 2 14 are fixedly connected at equal intervals inside the embedded part 7 at the bottom of the beam. The pipe reserved groove 3 17 is the lowest reserved groove at the bottom of the embedded part 7 at the bottom of the beam, forming a vertical multi-layer pipe arrangement space with the pipe reserved groove 15 and the pipe reserved groove 2 16 above.

[0035] Reference Figure 1 and Figure 2The frame beam 11 has a side-embedded sleeve 3 12 inside, and a roof panel 11 is installed on the top of the side-embedded sleeve 3 12. The frame longitudinal beam 13 serves as a horizontal load-bearing component, supporting the roof panel 2 18 on top. It is fixedly connected to the frame beam 11 through the embedded part 7 at the bottom of the beam, forming a stable structural support system. The roof panel 2 18 is installed on the top of the frame longitudinal beam 13. The outer side of the pipe rack crossbeam 10 is equipped with a later steel beam 9. The middle of the outer wall of the upper frame beam 11 is equipped with a side-embedded sleeve 3 12. The top of the pipe rack crossbeam 10 is connected to the column side embedded part 6. The outer side is pre-modulated connection node for later installation of the later steel beam 9.
[0036] Specifically, the frame beam 1 has a side-embedded sleeve 3 12 inside, and a roof panel 11 is installed on the top of the side-embedded sleeve 3 12. The frame longitudinal beam 13 serves as a horizontal load-bearing component, supporting the roof panel 2 18 on top. It is fixedly connected to the frame beam 1 through the embedded part 7 at the bottom of the beam, forming a stable structural support system. The roof panel 2 18 is installed on the top of the frame longitudinal beam 13. A later steel beam 9 is installed on the outside of the pipe rack crossbeam 10. The side-embedded sleeve 3 12 is installed in the middle of the outer wall of the upper frame beam 11. The top of the pipe rack crossbeam 10 is connected to the column side embedded part 6. The outer side has a pre-set modular connection node for the later installation of the later steel beam 9.
[0037] Working principle: Embedded parts 6 are installed on the side of the column during the construction of the concrete column. Bolt holes or welding interfaces are reserved at the top. The pipe rack beam 10 is directly installed later to form a vertical pipe support fulcrum. The outer side of the pipe rack beam 10 can be connected to the steel beam 9 later to meet the needs of process pipeline span adjustment without additional drilling or welding damage to the column. Embedded parts 7 are installed at the bottom of the beam along the bottom of the frame longitudinal beam 13 at equal intervals. They are welded to the main reinforcement of the frame beam 14 to form a horizontal load transfer channel. Pipe reserved groove 15, pipe reserved groove 2 16, and pipe reserved groove 3 17 are opened at the bottom of the embedded parts 7. The width of the groove is prefabricated according to the outer diameter of commonly used pipes. The pipes can be directly inserted into the grooves later. Inside, U-shaped clamps are used for fixing to avoid drilling into the beam. Sleeve 1 (3) and Sleeve 2 (8) are pre-embedded on both sides of the beam, with the sleeve axis aligned with the pipe direction, serving as a positioning channel for the pipe passing through the beam. The inner wall of the sleeve is pre-threaded or has anti-slip ridges to enhance the connection rigidity between the pipe and the beam. Roof slab 1 (11) and Roof slab 2 (18) are connected to frame beam 1 (1) through sleeve 3 (12) embedded on the side of the beam. The sleeve penetrates the floor slab and the beam. The inner diameter of sleeve 3 (12) embedded on the side of the beam is 20-30mm larger than the outer diameter of the pipe to allow for thermal expansion and contraction displacement. At the same time, a waterproof wing ring is installed at the top of the sleeve to prevent water seepage from the floor. During the civil engineering design phase, the possible loads of the process pipes are calculated according to 3.The 0m width range is uniformly included in the floor live load to avoid structural reinforcement due to insufficient load later. Frame beam 14 and frame longitudinal beam 13 adopt a variable cross-section design, increasing the reinforcement ratio in the mid-span area by 15% to 20% to enhance the shear and bending resistance of the embedded area. The pipeline load is transferred to the main structure through embedded parts 6 on the side of the pipe rack beam 10 or embedded parts 7 on the bottom of the beam, frame longitudinal beam 13 and frame beam 14. The bond strength between the embedded parts and the concrete ensures uniform load distribution. When the process pipeline needs to cross the frame longitudinal beam 13, it is directly fixed using the reserved groove of the embedded part 7 at the bottom of the beam. Small-diameter pipelines are installed with sliding supports through bolt holes in the groove, allowing ±10mm radial displacement to compensate for thermal expansion. Large-diameter pipelines have stiffening plates welded on both sides of the groove to form rigid support nodes to avoid stress concentration at the bottom of the beam. When the pipeline passes through the floor, it is positioned by embedded sleeve 12 on the side of the beam. The guide ridge on the inner wall of the sleeve ensures that the verticality error of the pipeline is ≤3‰. The top uses a flexible... The adjusting flange is fixed to roof panels 11 and 18, eliminating the need for on-site floor excavation. Later, steel beams 9 can slide or be spliced along the outside of pipe rack beams 10. Different pipe spans are matched using bolt hole spacing, resolving the issue of unclear spans during process planning. When process changes require pipe position adjustments, only the bolts at the corresponding nodes need to be removed, and the pipes can be reinstalled at other pre-embedded points in the same area. This avoids the lengthy process of beam removal, reinforcement, and reconstruction required in traditional renovations, improving construction efficiency by over 60%. Pre-reserved interfaces shorten project cycles by 20%–30%, and loads are factored into the main design in advance, avoiding structural hazards caused by later load additions. This avoids the need to remove main beams for subsequent pipe modifications and maintenance, a problem encountered in recent years where multiple workshop internal pipe rack load-reserving projects have faced challenges where process piping cannot be fully specified in the civil engineering design, requiring advance reservation by the civil engineering team, but the location cannot be clearly defined.
