[0003] The single-layer pipe racks commonly used in the present technology usually adopt a longitudinal single-layer steel beam system set on the column, or a traditional open section (H-beam and I-beam) truss structure. This type of steel beam has a large cross section, uses a large amount of steel beams, and the overall layout is cumbersome and uneconomical. Moreover, when supporting pipes, the number that can be arranged is relatively small, and as the service time is extended, the placement of the pipes will also become unstable.

[0004] Therefore, it is necessary to propose a triangular truss assembly structure for supporting pipelines to solve or at least alleviate the above-mentioned defects. Utility Model Content

The top end of the first oblique web member is connected to the upper chord tube and is located near a transverse web member. The top end of the second oblique web member is connected to the upper chord tube and is located near an adjacent transverse web member. The bottom ends of the first oblique web member and the second oblique web member are both connected to the lower chord tube and are located directly below the middle of the two transverse web members.

[0011] Preferably, the upper support assembly includes an upper support beam and two upper angle steels arranged laterally opposite each other.

[0017] Preferably, the number of grooves in the upper support beam is greater than the number of grooves in the lower support steel plate.

[0018] Preferably, it also includes a crossbeam edge sealing plate and a cable tray, with both ends of the upper support crossbeam extending out of the upper angle steel, the crossbeam edge sealing plate connected to one end of the upper support crossbeam, and the cable tray connected to the top of the crossbeam edge sealing plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides a triangular truss assembly structure for supporting pipelines, including a truss mechanism, an installation support mechanism, and two support units arranged longitudinally opposite each other. The truss mechanism includes a lower chord tube, two upper chord tubes, two sets of diagonal web members, and multiple horizontal web members. The two upper chord tubes are arranged laterally opposite each other, and the multiple horizontal web members are arranged longitudinally at intervals and connected between the two upper chord tubes. The ends of the two upper chord tubes are respectively connected to the two support units. The lower chord tube is located directly below the middle of the two upper chord tubes, and the two upper chord tubes are respectively connected to the lower chord tube through a set of diagonal web members. The installation support mechanism includes an upper support assembly and a lower support assembly. The upper support assembly is connected to the upper chord tube, and the lower support assembly is connected to the lower chord tube.

[0036] Please see the appendix Figure 1-7 This utility model provides a triangular truss assembly structure for supporting pipelines, comprising a truss mechanism 10, a mounting support mechanism 20, and two support units 30 arranged longitudinally opposite each other. First, it should be noted that in this application, "longitudinal" refers to the direction of pipeline extension, and "lateral" refers to the horizontal extension direction perpendicular to the longitudinal direction, as shown in the accompanying drawings. Unlike the single-layer pipe racks commonly used in the prior art, which typically employ a longitudinal single-layer steel beam system mounted on columns, or traditional open-section (H-beams and I-beams) truss structures, this application addresses the aforementioned shortcomings of the prior art by providing a triangular truss assembly structure for supporting pipelines, as detailed below:

[0037] The truss mechanism 10 includes a lower chord tube 110, two upper chord tubes 120, two sets of diagonal web member assemblies 130, and multiple transverse web members 140. The two upper chord tubes 120 are arranged opposite each other in the transverse direction, and the multiple transverse web members 140 are arranged longitudinally at intervals and connected between the two upper chord tubes 120. The ends of the two upper chord tubes 120 are respectively connected to the two support units 30. The lower chord tube 110 is located directly below the middle of the two upper chord tubes 120, and the two upper chord tubes 120 are respectively connected to the lower chord tube 110 through a set of diagonal web member assemblies 130. The mounting support mechanism 20 includes an upper support assembly 210 and a lower support assembly 220. The upper support assembly 210 is connected to the upper chord tube 120, and the lower support assembly 220 is connected to the lower chord tube 110. Both the upper support assembly 210 and the lower support assembly 220 have recessed grooves 230 for placing pipes.

[0038] Specifically, the triangular truss assembly structure for supporting pipelines in this application includes a truss mechanism 10, an installation support mechanism 20, and two support units 30. The support units 30 are used to support the ends of the truss mechanism 10 to improve the installation stability of the truss mechanism 10. The truss mechanism 10 serves as the load-bearing main body of the entire assembly structure. It adopts a three-dimensional spatial structure with a triangular cross-section, which significantly reduces the amount of steel used while ensuring structural stability. The installation support mechanism 20 is then used for pipeline installation, thereby forming a stable pipeline installation system.

[0039] The truss mechanism 10 includes a lower chord tube 110, two upper chord tubes 120, two sets of diagonal web member assemblies 130, and multiple transverse web members 140. The lower chord tubes 110 and the two upper chord tubes 120 form a triangular cross-section, a stable geometric shape that is generally not prone to deformation. The diagonal web member assemblies 130 and the transverse web members 140 are connected to form a three-dimensional spatial structure. The multiple transverse web members 140 are longitudinally spaced and connected between the two upper chord tubes 120 to improve the lateral strength between the two upper chord tubes 120 and prevent lateral deformation. Preferably, the interval between two adjacent transverse web members 140 can be set to 260 cm. 280cm, which can be set by those skilled in the art according to actual conditions; the two upper chord tubes 120 are respectively connected to the lower chord tube 110 through a set of diagonal web member assemblies 130. The diagonal web member assemblies 130 can be used to distribute the load and improve the overall stiffness; the lower chord tube 110 and the upper chord tube 120 are usually in the form of round tubes. When the round tubes are welded to each web member, intersecting line break welding can be used, which is convenient for construction and can save the node plate. Moreover, all components and nodes of the truss can be manufactured in the factory, and the finished product has high quality. Then, the installation support mechanism 20 is used to support the pipes, avoiding direct welding of the pipes to the truss mechanism 10, which would affect the structural strength of the truss mechanism 10.

[0040] Furthermore, after the truss mechanism 10 is welded as a whole, the installation support mechanism 20 can be installed and connected, which includes an upper support component 210 and a lower support component 220. The upper support component 210 is used to arrange the pipe on the upper layer of the structure (on the upper chord pipe 120), and the lower support component 220 is used to arrange the pipe on the lower layer of the structure (on the lower chord pipe 110), thus forming a double-layer pipe arrangement, which fully improves the space utilization. Both the upper support component 210 and the lower support component 220 have recessed grooves 230, which are used for placing the pipe, thereby improving the stability of the pipe placement. Normally, only the contact points and planes of the pipe are welded. However, the pipe will vibrate during the process of conveying materials or ventilating, which can easily lead to loosening over time. Therefore, placing the pipe in the corresponding groove 230 before welding can further improve the stability of the pipe placement.

[0041] In a preferred embodiment of this utility model, each set of diagonal bracing components 130 includes multiple diagonal bracing units arranged sequentially along the longitudinal direction, and one diagonal bracing unit is provided between every two transverse bracing units 140; wherein, each diagonal bracing unit includes a first diagonal bracing unit 131 and a second diagonal bracing unit 132, the top end of the first diagonal bracing unit 131 is connected to the upper chord tube 120 and is disposed near one transverse bracing unit 140, the top end of the second diagonal bracing unit 132 is connected to the upper chord tube 120 and is disposed near the other adjacent transverse bracing unit 140, and the bottom ends of the first diagonal bracing unit 131 and the second diagonal bracing unit 132 are both connected to the lower chord tube 110 and disposed near the middle directly below the two transverse bracing units 140.

[0042] It should be noted that multiple sets of diagonal bracing units are arranged longitudinally to ensure the uniformity of the diagonal bracing distribution throughout the structure. The presence of one diagonal bracing unit between every two transverse bracing units 140 ensures that each connection node at a transverse bracing unit 140 is equipped with a diagonal bracing unit to strengthen the structural strength at the node. Each diagonal bracing unit includes a first diagonal bracing unit 131 and a second diagonal bracing unit 132. By using two diagonal bracing units, the connection strength at the nodes of the two transverse bracing units 140 is strengthened respectively. Therefore, the first diagonal bracing unit... The top end of the first oblique web 131 is connected to the upper chord tube 120 and is positioned near a horizontal web 140. The top end of the second oblique web 132 is connected to the upper chord tube 120 and is positioned near another adjacent horizontal web 140. The bottom ends of both extend obliquely downward to connect to the lower chord tube 110. It should be noted that the bottom ends of both should be positioned close to the middle and directly below the two horizontal webs 140 to ensure the uniformity of the distribution of the first oblique web 131 and the second oblique web 132, to ensure balanced force distribution, and thus ensure stability.

[0043] In a preferred embodiment of the present invention, the upper support assembly 210 includes an upper support beam 211 and two upper angle steels 212 arranged laterally opposite each other. The two upper angle steels 212 are respectively connected to the two upper chord tubes 120. The two ends of the upper support beam 211 are respectively connected to the two upper angle steels 212, and the upper support beam 211 has a plurality of grooves 230 arranged laterally at intervals.

[0044] It should be noted that the upper angle steel 212 facilitates the connection of the upper support beam 211 to the upper chord tube 120. It has high tensile and compressive strength and can withstand large loads. The unique L-shaped structure of the angle steel makes it easy to connect to the circular chord tube by welding a semi-enclosed connection. The two ends of the upper support beam 211 are then welded to the two upper angle steels 212 respectively, so as to span across the two upper chord tubes 120 for pipe placement. When placing, it can be placed in the groove 230 of the upper support beam 211.

[0045] In a preferred embodiment of the present invention, each of the transverse web members 140 is provided with an upper support assembly 210.

[0046] It is worth noting that, considering that the truss mechanism 10 has not only the transverse web member 140 for lateral support, but also the top support of the adjacent first diagonal web member 131 and second diagonal web member 132, the structural strength at the transverse web member 140 is relatively stable. The upper support component 210 is set here to ensure the stress balance of the structure and avoid stress concentration at weak points.

[0047] In a preferred embodiment of this utility model, a lower support component 220 is provided directly below each of the upper support components 210. Each lower support component 220 includes a lower support steel plate 221 and a lower angle steel 222. The lower angle steel 222 is connected to the lower chord tube 110, and the lower support steel plate 221 is connected to the lower angle steel 222. The lower support steel plate 221 has a plurality of grooves 230 arranged laterally at intervals.

[0048] It is worth noting that, considering the distribution of the diagonal web members, the top of each diagonal web member is close to the horizontal web member 140 of the upper chord tube 120. Therefore, due to the inclined arrangement, there is sufficient space directly below the horizontal web member 140 of the upper chord tube 120 (at the upper support assembly 210) to weld the lower angle steel 222, and to weld the lower support steel plate 221 onto the lower angle steel 222. It is worth mentioning that, considering the stress and structural stability, the lower layer is made of steel plate, which is lighter in weight, and also has sufficient contact surface to form a groove 230 for the placement of the pipe.

[0049] Furthermore, the grooves 230 of the upper support beam 211 and the lower support steel plate 221 are both arc-shaped.

[0050] It should be noted that the pipes in the factory area are usually circular. Considering the matching characteristics, the groove 230 can also be set as an arc groove to correspond with the pipes in the factory area and facilitate placement.

[0051] Furthermore, each of the support units 30 includes two supports 310 arranged laterally opposite each other, the bottom end of the supports 310 being used to mount on the frame, and the top end of the supports 310 being welded to the end of the upper chord tube 120.

[0052] It should be understood that the support 310 can be in the form of a base and two steel plates cross-welded together to improve the support rigidity, and one of the steel plates can be extended upward to be welded to the upper chord tube 120 to achieve the support effect.

[0053] Furthermore, it also includes an edge sealing steel plate 150, which is connected to the end of the upper chord tube 120.

[0054] It should be noted that the edge sealing steel plate 150 is used to seal the end of the upper chord tube 120 to prevent the end of the upper chord tube 120 from being exposed, thereby causing various dust and impurities to fly into the interior of the upper chord tube 120.

[0055] Furthermore, the number of grooves 230 in the upper support beam 211 is greater than the number of grooves 230 in the lower support steel plate 221.

[0056] It should be noted that, considering the need to consider the structural strength of the lower steel pipe support, it is not advisable to support too many. Therefore, the number of grooves 230 in the lower support steel plate 221 should be reduced to ensure the stability of the structural support and prevent excessive weight.

[0057] Furthermore, it also includes a beam edge sealing plate 160 and a cable tray 170. The two ends of the upper support beam 211 extend out of the upper angle steel 212 respectively. The beam edge sealing plate 160 is connected to one end of the upper support beam 211, and the cable tray 170 is connected to the top of the beam edge sealing plate 160.

[0058] It should be understood that the crossbeam sealing plate 160 is used for the installation of the cable tray 170. It makes full use of the structural space by utilizing the cantilevered feature of the end of the upper support crossbeam 211, so that the cable tray 170 is connected to the top of the crossbeam sealing plate 160. The cable tray 170 is used for the cable to pass through and be placed. The length of the upper support crossbeam 211 can be set to at least 1.2m to ensure that both ends can be extended.

[0059] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
