Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a prefabricated pipe support and an assembled pipe support. Background Technology

[0002] In pipeline construction across petrochemical, municipal engineering, power, and metallurgical industries, concrete pipe supports serve as core structures supporting pipeline systems and are widely used. Traditional pipe supports are primarily formed using a cast-in-place method, involving on-site formwork erection, rebar tying, and concrete pouring. This construction method has inherent drawbacks: a long construction cycle requiring significant on-site curing time; substantial on-site wet work, resulting in significant environmental impact and substantial pressure on material storage and waste disposal; and construction quality is easily affected by environmental temperature, humidity, and worker skill levels, making it difficult to effectively guarantee the stability of structural dimensions and concrete strength. Furthermore, cast-in-place operations in the high-altitude, frequently overlapping environments of pipe galleries also pose significant safety risks.

[0003] To overcome the shortcomings of cast-in-place structures, prefabricated concrete structures have emerged and have been initially applied in the field of pipe supports. Existing prefabricated concrete pipe support solutions mostly involve assembling and installing prefabricated full-height columns and prefabricated single beams on-site. While this method reduces some on-site wet work, its practical promotion and application have revealed a series of technical problems that urgently need to be solved:

[0004] Firstly, the traditional precast column + precast beam model means that each independent "gate" or "H" shaped support requires multiple independent hoisting operations (at least one column and one beam). For utility tunnel projects stretching for several kilometers, the sheer number of supports results in an astonishing number of hoisting operations, leading to low hoisting efficiency and high costs for machinery and labor. More importantly, the beam-column connection nodes are usually located at the points of greatest stress at the beam ends, making the treatment of these nodes a technical challenge. While complex dry connections (such as flanges and prestressed steel cables) offer fast construction speeds, the cost of the connectors is high, and the requirements for manufacturing and installation precision are extremely stringent. Traditional wet connections (such as grouting with pre-reinforced steel sleeves or post-cast concrete) still require on-site rebar splicing, formwork, and pouring, making it difficult to control the connection quality. Furthermore, it is necessary to wait for the concrete at the node to reach the design strength before continuing loading or subsequent construction, thus not completely eliminating the dilemma of long construction cycles and low efficiency.

[0005] Secondly, the existing prefabricated cross beams and vertical beams mainly form a standard main support frame, which has a single function and lacks flexibility. In actual engineering, the pipeline layout in the utility tunnel is complex and variable: for example, after the inner space of the utility tunnel is fully occupied by main pipelines, the pipeline layout space is often insufficient, and it is necessary to erect new, modified or smaller-sized pipelines without adding additional main frames; for another example, at the end of the direction of the utility tunnel, at corners or at intersections with other utility tunnels, reliable supports need to be provided for the turning of pipelines. Facing these demands, traditional prefabricated supports are often helpless, and can only be solved by additionally customizing non-standard components or returning to the cast-in-place method, which seriously violates the original intention of standardized and industrialized production of prefabricated buildings, leads to the breakage of the design, production and construction chain, and cannot achieve rapid and economical flexible response.

[0006] Thirdly, the discretized column and beam units are connected through limited nodes, and their overall stability and structural redundancy are usually lower than those of cast-in-place structures. When it is necessary to construct multi-span continuous support structures such as "mouth" shape and "day" shape, it is required to prefabricate a large number of components of different specifications and carry out complex assembly on site, with low degree of modularization and standardization and poor system scalability. At the same time, the support column and the upper support assembly are usually of split type, which adds another potential weak connection point and affects the overall stiffness and bearing efficiency of the entire support system.

[0007] Therefore, there is an urgent need in the art for a new type of prefabricated pipeline support solution, which should be able to realize truly efficient assembly, significantly reduce on-site operation workload and hoisting times, and at the same time have strong space adaptability and expansion capability, can flexibly cope with various complex working conditions of pipeline layout, so as to promote the development of pipeline support structures in a more efficient, more economical and more reliable direction. Summary of the Invention

[0008] Aiming at the deficiencies existing in the prior art, the present utility model provides a prefabricated pipeline support and a prefabricated pipeline support system. By arranging a cantilever beam on one side of the prefabricated cross beam, when the pipeline layout space inside the utility tunnel is insufficient, the cantilever beam can be used to erect additionally added pipelines, effectively expanding the pipeline accommodation capacity.

[0009] The present utility model achieves the above technical objectives through the following technical means.

[0010] A prefabricated pipeline support comprises prefabricated vertical beams and prefabricated cross beams, wherein two adjacent prefabricated vertical beams are connected through at least one prefabricated cross beam; a cantilever beam is arranged on one side of at least one of the prefabricated cross beams.

[0011] Further, at least one of the two ends of the prefabricated cross beam is provided with a transverse cantilever beam extending along the transverse direction.

[0012] Furthermore, a longitudinal cantilever beam extending along the longitudinal direction is provided at the junction of the precast horizontal beam and the precast vertical beam.

[0013] Furthermore, at the two junctions of the precast horizontal beam and the precast vertical beam, there are longitudinal cantilever beams extending along the longitudinal direction, and the two longitudinal cantilever beams are connected by a butt beam.

[0014] Furthermore, each of the two ends of the precast horizontal beam is provided with a transverse cantilever beam extending in the transverse direction, and each of the two junctions between the precast horizontal beam and the precast vertical beam is provided with a longitudinal cantilever beam extending in the longitudinal direction. The two longitudinal cantilever beams are connected by a butt beam.

[0015] Furthermore, the prefabricated vertical beams and prefabricated horizontal beams form a portal-shaped structure, an H-shaped structure, a square-shaped structure, a sun-shaped structure, or an eye-shaped structure.

[0016] A prefabricated pipe support includes a support column and at least one of the prefabricated pipe supports; a prefabricated vertical beam of the prefabricated pipe support assembly is connected to one end of the support column; the other end of the support column is connected to a base or embedded in the foundation.

[0017] Furthermore, several prefabricated pipe supports are connected in series, and the prefabricated vertical beams of adjacent prefabricated pipe support assemblies are connected to each other.

[0018] Furthermore, the support column and its adjacent prefabricated pipe support are prefabricated as a whole.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. The prefabricated pipe support and assembled pipe support of the present invention, by setting a cantilever beam on one side of the prefabricated crossbeam, can support additional pipes when the space for pipe arrangement inside the pipe gallery is insufficient, thereby effectively expanding the pipe capacity.

[0021] 2. The prefabricated pipe support and assembled pipe support of the present invention, by setting a longitudinal cantilever beam at the intersection of prefabricated horizontal beam and prefabricated vertical beam, can install turning pipes at the end or corner of the pipe gallery, and can realize pipe direction conversion and continuous laying.

[0022] 3. The prefabricated pipe support and assembled pipe support of the present invention, which are connected by a butt beam between the two longitudinal cantilever beams, can enhance the overall stability and load-bearing capacity of the support and can support pipe layouts with longer spans at the same time.

[0023] 4. The prefabricated pipe support and assembled pipe support of the present invention, by setting transverse cantilever beams and longitudinal cantilever beams simultaneously through prefabricated crossbeams and connecting them to the connecting beam, can comprehensively solve the needs of pipe space expansion and turning, and improve the adaptability and multifunctionality of the support.

[0024] 5. The prefabricated pipe support and assembled pipe support of the present invention form a gate-shaped, H-shaped, square-shaped, sun-shaped, or eye-shaped structure through the prefabricated vertical beams and prefabricated horizontal beams. This allows for flexible selection of support form according to the actual pipe gallery space and pipe distribution, improving the design versatility and installation convenience.

[0025] 6. The prefabricated pipe supports and assembled pipe supports described in this invention achieve rapid assembly and fixation of support components through the connection between support columns and bases, reducing construction difficulty and cost while ensuring a firm connection between the supports and the foundation. By sequentially connecting several prefabricated pipe support components in series, the scale of the pipe support system can be expanded to meet the needs of large-scale utility tunnel projects, achieving modular construction and maintenance. The support columns and prefabricated pipe support components are prefabricated as a whole, which improves structural integrity and strength, reduces on-site assembly steps, and enhances construction efficiency and reliability.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "axial," "radial," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] like Figure 1 As shown, the prefabricated pipe support of this utility model includes prefabricated vertical beams 3 and prefabricated horizontal beams 4. Adjacent prefabricated vertical beams 3 are connected by at least one prefabricated horizontal beam 4. A cantilever beam is provided on one side of at least one prefabricated horizontal beam 4. One side of the prefabricated horizontal beam 4 can be one end of either end of the prefabricated horizontal beam 4, or one side of either side of the prefabricated horizontal beam 4. This utility model, by providing a cantilever beam on one side of the prefabricated horizontal beam 4, achieves the effect of effectively expanding the pipe capacity by using the cantilever beam to support additional pipes when there is insufficient space for pipe arrangement inside the pipe gallery.

[0038] For ease of explanation later, the height direction will be defined as vertical, a direction perpendicular to the height will be defined as horizontal, and a direction perpendicular to both the horizontal and vertical directions will be defined as longitudinal.

[0039] Example 1

[0040] like Figure 1 As shown, the prefabricated pipe support described in Embodiment 1 includes a prefabricated vertical beam 3 and a prefabricated horizontal beam 4. The height direction of the prefabricated vertical beam 3 is vertical, and the upper ends of the two prefabricated vertical beams 3 are connected by the prefabricated horizontal beam 4. The two prefabricated vertical beams 3 and the prefabricated horizontal beam 4 form a portal structure.

[0041] One end of the precast beam 4 is provided with a transverse cantilever beam 5 extending laterally, which provides additional pipe laying space on one side of the pipe support, effectively solving the problem of insufficient pipe layout space inside the pipe gallery. This eliminates the need for additional support structures, making it economical and efficient. In some embodiments, both ends of the precast beam 4 are provided with transverse cantilever beams 5 extending laterally, providing additional pipe laying space on both sides of the pipe support and effectively expanding the pipe capacity.

[0042] When the prefabricated pipe support in Embodiment 1 is located at the end of the pipe or at a corner, a turning pipe needs to be installed on the prefabricated pipe support. Therefore, at the junction of the prefabricated horizontal beam 4 and the prefabricated vertical beam 3, a longitudinal cantilever beam 6 extending longitudinally is provided, which can realize the pipe direction conversion and continuous laying. The two longitudinal cantilever beams 6 are connected by a connecting beam 7. The two longitudinal cantilever beams 6 and the connecting beam 7 can be regarded as a longitudinal cantilever beam assembly. The longitudinal cantilever beam assembly designed in this way can enhance the stability and load-bearing capacity of the cantilever beam and can support the layout of pipes with longer spans at the same time.

[0043] There are two different types of prefabricated pipe supports in the middle and at the end of the pipe. In order to unify the product model and functional diversity, in embodiment 1, the two ends of the prefabricated crossbeam 4 are respectively provided with transverse cantilever beams 5 extending in the transverse direction, and the two junctions of the prefabricated crossbeam 4 and the prefabricated vertical beam 3 are respectively provided with longitudinal cantilever beams 6 extending in the longitudinal direction. The two longitudinal cantilever beams 6 are connected by a butt beam 7.

[0044] In Example 1, the prefabricated horizontal beam 4, prefabricated vertical beam 3, transverse cantilever beam 5, and longitudinal cantilever beam assembly can be prefabricated in one step.

[0045] Example 2

[0046] like Figure 2 As shown, based on Embodiment 1, the two prefabricated vertical beams 3 are connected at their midpoints by a prefabricated horizontal beam 4, and the two prefabricated vertical beams 3 and the prefabricated horizontal beam 4 form an H-shaped structure. The H-shaped structure provides two independent support spans, which facilitates the layered arrangement of pipes. A cantilever beam is provided on one side of the prefabricated horizontal beam 4 in the H-shaped structure. The cantilever beam can be any one of those in Embodiment 1, that is, the cantilever beam can be a transverse cantilever beam 5 and / or a longitudinal cantilever beam assembly.

[0047] Example 3

[0048] As Figure 3 shown, on the basis of Embodiment 1, the middle parts of the two prefabricated vertical beams 3 are connected by two prefabricated cross beams 4, and the two prefabricated vertical beams 3 and the two prefabricated cross beams 4 form a square-shaped structure. The square-shaped structure has high torsional rigidity and is suitable for working conditions with large spans and large pipe diameters. The square-shaped structure only requires hoisting of one component to realize a structure that can only be built by multiple beam and column components in the traditional solution, maximizing the construction efficiency. One side of any prefabricated cross beam 4 in the square-shaped structure is provided with a cantilever beam, and the cantilever beam can be any one of those in Embodiment 1, that is, the cantilever beam can be a transverse cantilever beam 5 and / or a longitudinal cantilever beam assembly.

[0049] In Embodiment 3, the prefabricated vertical beams 3 and the prefabricated cross beams 4 can also form a structure shaped like the Chinese character "Ri" or a structure shaped like the Chinese character "Mu", and one side of any prefabricated cross beam 4 is provided with a cantilever beam.

[0050] Embodiment 4

[0051] As Figure 4 shown, Embodiment 4 is a single-layer prefabricated pipe support, which comprises support columns 2 and the prefabricated pipe support assembly according to any one of Embodiment 1 or Embodiment 3; the lower end of the support column 2 is firmly connected to the concrete base 1 through embedded bolts, or the lower end of the support column 2 can be directly embedded in the foundation. The lower end of the prefabricated vertical beam 3 of the prefabricated pipe support assembly is butted with the upper end of the support column 2 by means of flanges or socket-type grouting. Through the connection between the support columns 2 and the base 1, the support assembly can be quickly assembled and fixed, reducing the construction difficulty and cost, and at the same time ensuring the effect of firm connection between the support and the foundation. Through the means of sequentially connecting a plurality of prefabricated pipe support assemblies in series, the scale of the pipe support system can be expanded to meet the needs of large-scale pipe gallery projects, and the effects of modular construction and maintenance can be achieved. The support column and the prefabricated pipe support assembly are integrally prefabricated, which can improve the structural integrity and strength, reduce on-site assembly steps, and improve construction efficiency and reliability.

[0052] In some embodiments, the support column 2 and the prefabricated pipe support assembly can also be integrally prefabricated.

[0053] Embodiment 5

[0054] For the convenience of description, any prefabricated pipe support in Embodiment 1 or Embodiment 3 is defined as an upper-layer support, and any prefabricated pipe support in Embodiment 2 is defined as a lower-layer support; as Figure 5As shown, Embodiment 5 is a series-type multi-layer prefabricated pipe support, including a support column 2, an upper support, and a lower support. One end of the support column 2 is connected to one end of the prefabricated vertical beam 3 of the lower support, and the other end of the support column 2 is connected to the base 1 or pre-embedded in the foundation. The other end of the prefabricated vertical beam 3 of the lower support is connected to one end of the prefabricated vertical beam 3 of the upper support. Both the upper and lower supports have cantilever beams. The support column 2 and the lower support can be prefabricated as a whole, facilitating on-site installation.

[0055] In some embodiments, multiple lower supports are connected in series to form a lower support group. One side of the lower support group is connected to the support column 2, and the other side of the lower support group is connected to the upper support.

[0056] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0057] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
