Description

Technical Field

[0001] The present invention relates to the technical field of pipe fitting connection, and particularly relates to a support member and a pipe fitting connection structure. Background Art

[0002] In recent years, with the need for national economic development, large-scale engineering construction projects are common, such as subway construction, new construction, renovation and expansion of airports, convention centers, museums, large intelligent buildings and other various large projects emerging in an endless stream. In these construction projects, the strong and weak power systems are complex, so a large number of power wiring operations are required, and the demand for pipe conduits is huge. During the process of arranging pipe conduits, for a relatively long line, it needs to be spliced by multiple pipe conduits. In the prior art, the connection between two adjacent pipe conduits is mainly achieved through fasteners or clamps. This connection method has poor sealing performance and cannot achieve effective waterproofing. At the same time, the fasteners or clamps hold the pipe conduits tightly from the butt joint of two adjacent pipe conduits, which easily causes the pipe conduits to deform, resulting in ineffective butt joint of two adjacent pipe conduits.

[0003] For example, the Chinese utility model patent with the publication number CN208651878U and the name of pipe fitting connection structure and pipeline discloses a pipe fitting connection structure including: a first pipe fitting, the first pipe fitting includes a first connection end; a second pipe fitting, the second pipe fitting includes a second connection end, a first notch is provided on the second connection end, and the first notch includes a first side surface and a second side surface opposite to the first side surface, the first connection end is inserted into the second connection end; and a first fastener, the first fastener is arranged on the second connection end. The pipeline includes the above-mentioned pipe fitting connection structure. When installing the above-mentioned pipe fitting connection structure, the first connection end of the first pipe fitting is inserted into the second connection end of the second pipe fitting and the first pipe fitting and the second pipe fitting are communicated with each other, and then the first side surface and the second side surface of the first notch are tightened by the first fastener, so as to achieve the purpose of fixedly connecting the first pipe fitting and the second pipe fitting. During the tightening process of the first fastener, the butt joint of the first pipe fitting and the second pipe fitting will deform and generate a gap, and the two pipe fittings cannot be effectively butted, and the sealing performance and waterproof performance are poor.

[0031] As Figures 1 to 3 shown, the present invention discloses a support member 1, including an annular main body 10, an end face 100 of the annular main body 10, and / or, a support convex portion 11 is provided on the inner wall 101. The support convex portion 11 extends out of the end face 100 of the annular main body 10 along the axial direction of the annular main body 10 (as Figure 1 and Figure 3 shown by the A direction in

[0032] That is to say, the support member 1 is mainly composed of an annular body 10 and support protrusions 11. Among them, the support protrusions 11 extend along the axial direction of the annular body 10, and can be arranged on the end face 100 of the annular body 10, or on the inner wall 101 of the annular body 10, or partially on the end face 100 of the annular body 10 and partially on the inner wall 101 of the annular body 10, as long as the support protrusions 11 can extend out of the end face 100 of the annular body 10 and can extend into the interior of the pipe fitting 2 to support the pipe fitting 2.

[0033] Specifically, refer to Figure 1 and in combination with Figure 3 As shown, in this embodiment, the support protrusions 11 can extend out from both end faces 100 of the annular body 10. During the docking process of the pipe fitting 2, the pipe fitting 2 is located on both sides of the support member. The support member 1 is close to the end of the pipe fitting 2, and the extended support protrusions 11 can be inserted into the interior of the pipe fitting 2, and the upper side surface 112 of the support protrusions 11 can be attached to the inner wall of the pipe fitting 2 to support and seal the pipe fitting 2, preventing the pipe fitting 2 from deforming under the action of the fastener, and ensuring that the adjacent pipe fittings 2 located on both sides of the support member 1 can be effectively and reliably docked.

[0034] By adopting the above technical solution, by using a support member composed of an annular body and support protrusions, it is possible to support and seal the pipe fitting after the pipe fitting docking is completed, prevent the pipe fitting from deforming under the action of the fastener, ensure that the adjacent pipe fittings located on both sides of the support member can be effectively and reliably docked, and further improve the sealing performance and waterproof performance at the docking part of the adjacent pipe fittings, so that the pipe line system formed by connecting the pipe fittings can work more safely and reliably.

[0035] It should be noted that the present invention does not limit the specific shape of the annular body, and can be specifically set according to the shape of the pipe fitting, as long as the support member can effectively dock with the pipe fitting and support the pipe fitting. Specifically, in the present invention, the cross-section of the annular body 10 is any one of a circular ring, an elliptical ring, a polygonal ring, or an irregular ring composed of curves and curves, curves and straight lines, and straight lines and straight lines.

[0036] Refer to Figures 1 to 3As shown, in this embodiment, a flange 12 is provided on the end face 100 and / or the outer wall 102 of the annular body 10. The flange 12 extends along the axial direction of the annular body 10 and is used for sleeving on the outer wall of the end of the pipe fitting 2. That is to say, a flange 12 is also provided on the annular body 10. The flange 12 extends along the axial direction of the annular body 10 and can be arranged on the end face 100 of the annular body 10. That is to say, the root of the flange 12 is arranged on the end face 100 of the annular body 10 and extends in a direction away from the end face 100 from the end face 100 of the annular body 10. At this time, the outer side surface of the flange 12 can be smoothly butted with the outer wall 102 of the annular body 10 to form an integral side surface. At the same time, the flange 12 can also be arranged on the outer wall 102 of the annular body 10. That is to say, the root of the flange 12 is attached to the outer wall 102 of the annular body 10.

[0037] Specifically, refer to Figure 3 and in combination with Figure 1 As shown, in this embodiment, the flange 12 forms a complete circumference around the circumferential direction of the annular body 10 (such as the T direction shown in Figure 1 and Figure 2 ). When docking with the end of the pipe fitting 2, the flange 12 can be sleeved on the end of the pipe fitting 2 and attached to the outer wall of the pipe fitting 2 to seal the connection part of the pipe fitting 2 from the outside. Combined with the support convex part 11 sealing the connection part of the pipe fitting 2, a double-layer seal is formed to improve the sealing effect of the connection part of the pipe fitting 2. At the same time, sealing materials (such as PTFE tape, sealing rubber strips or sealing glue, etc.) can also be added between the inner wall of the flange 12 and the outer wall of the pipe fitting 2, between the end face of the annular body 10 and the end of the pipe fitting 2, and between the upper side surface 112 of the support convex part 11 and the inner wall of the pipe fitting 2, so that the support member 1 and the pipe fitting 2 are better sealed.

[0038] In other embodiments, the flange can also be intermittently arranged in the circumferential direction of the annular body. The present invention does not limit this and can be reasonably set according to actual needs as long as it is ensured that the flange of the support frame is sleeved on the end of the pipe fitting.

[0039] It should be noted that the present invention does not limit the specific quantity and distribution of the support convex parts, and can be specifically set according to the shape and size of the annular body as long as the support convex parts on the support member can effectively dock with the pipe fitting and support the pipe fitting.

[0040] Specifically, refer to Figures 1 to 3As shown, in this embodiment, the supporting convex portions 11 are evenly distributed along the circumferential direction of the annular body 10. That is to say, around the circumferential direction of the annular body 10, a plurality of supporting convex portions 11 are evenly distributed on the annular body 10. When docking with the end of the pipe fitting 2, the evenly distributed plurality of supporting convex portions 11 can all extend into the interior of the pipe fitting 2, fit with the inner wall of the pipe fitting 2, and perform multi-point support on the pipe fitting 2, enabling the pipe fitting 2 to be stressed more evenly, preventing the pipe fitting 2 from deforming under the action of the fastener, and ensuring that the adjacent pipe fittings 2 located on both sides of the support member 1 can be effectively and reliably docked.

[0041] More specifically, referring to Figures 1 to 3 As shown, in this embodiment, two supporting convex portions 11 are symmetrically arranged on the annular body 10. The supporting convex portion 11 is a sheet-like structure provided on the inner wall 101 of the annular body 10. In the axial direction of the annular body 10, both sides of the supporting convex portion 11 extend out of the end face 100 of the annular body 10.

[0042] That is to say, the two supporting convex portions 11 are symmetrically arranged on the inner walls 101 on the upper and lower sides of the annular body 10. The upper side face 112 of the supporting convex portion 11 is fixedly and fittingly connected to the inner wall 101 of the annular body 10. The supporting convex portion 11 is a sheet-like structure, and both sides of the supporting convex portion 11 symmetrically extend out from the two end faces 100 of the annular body 10 along the axial direction of the annular body 10. When docking with the pipe fitting 2, the supporting convex portion 11 extends into the interior of the pipe fitting 2, the end face 100 of the annular body 10 abuts against the end face of the pipe fitting 2, and the upper side face 112 of the sheet-like supporting convex portion 11 can fit with the flat inner wall of the pipe fitting 2, having a relatively large fitting area, and can effectively and reliably support the pipe fitting 2 to prevent the pipe fitting 2 from deforming.

[0043] Referring to Figure 1 And in combination with Figure 3 As shown, in this embodiment, the surface of the supporting convex portion 11 facing the inner side of the annular body 10 is a convex surface 110. By setting the surface of the supporting convex portion 11 facing the inner side of the annular body 10 as the convex surface 110, the cross-section of the supporting convex portion 11 can be gradually thickened from the end far away from the annular body 10 to the end face 100 of the annular body 10, improving the strength of the supporting convex portion 11. At the same time, the convex surface 110 can also disperse the force exerted on the supporting convex portion 11 by the inner wall of the pipe fitting 2, ensuring that the convex surface 110 can stably and effectively support the pipe fitting 2 from the inside.

[0044] Preferably, the convex surface 110 is an arc-shaped convex surface, and the surface of the arc-shaped convex surface is smooth and will not scratch the pipeline passing through the pipe fitting 2 and the support member 1. In other embodiments, the convex surface can also be a trapezoidal convex surface or other types of convex surfaces. The present invention does not limit this and can be reasonably set according to actual needs as long as the strength of the supporting convex portion can be ensured.

[0045] In addition, referring toFigure 1 and in combination with Figure 3 As shown, in this embodiment, in the axial direction of the annular body 10, the side surface 111 of the supporting convex portion 11 away from the annular body 10 protrudes towards the direction away from the annular body 10, forming a convex surface. The side surface 111 of the supporting convex portion 11 away from the annular body 10 is set as a convex surface towards the direction away from the annular body 10. When docking with the pipe fitting 2, the front end of the convex surface first contacts the inner wall of the pipe fitting 2. As the supporting convex portion 11 continues to be inserted, the contact surface between the supporting convex portion 11 and the inner wall of the pipe fitting 2 will also become wider and wider until it reaches the width of the entire supporting convex portion 11. In this way, the convex surface plays the role of guiding the docking with the pipe fitting 2, facilitating the insertion of the supporting convex portion 11 into the pipe fitting, that is, facilitating the installation of the support member 1.

[0046] Preferably, the side surface 111 of the supporting convex portion 11 away from the annular body 10 is an arc-shaped convex surface, and the arc-shaped convex surface can guide the smooth insertion of the supporting convex portion 11 into the pipe fitting 2. In other embodiments, the side surface of the supporting convex portion away from the annular body can also be a trapezoidal convex surface, or other types of convex surfaces. The present invention does not limit this, and can be reasonably set according to actual needs as long as it can guide the supporting convex portion to insert into the pipe fitting.

[0047] Furthermore, in other embodiments, the number and specific shape of the supporting convex portions can be specifically set according to the shape and size of the annular body. For example, the supporting convex portions can also be formed in a complete circular shape around the circumference of the annular body. The present invention does not limit this, as long as the supporting convex portions on the support member can effectively dock with the pipe fitting and support the pipe fitting.

[0048] In this embodiment, the annular body 10 and the supporting convex portion 11 are integrally formed of aluminum alloy material, and the annular body 10, and / or, the supporting convex portion 11 has electrical conductivity. That is to say, both the annular body 10 and the supporting convex portion 11 are processed from aluminum alloy material, and the two are an integral whole formed by integral molding. Therefore, both the annular body 10 and the supporting convex portion 11 have electrical conductivity, which can connect the pipe fittings 2 on both sides of the support member 1, enabling the entire pipeline formed by the pipe fittings 2 to act as the grounding wire of the power system, and eliminating the need to separately set grounding terminals and grounding wires in the pipeline, simplifying the structure of the pipeline. When the supporting convex portions 11 at both ends of the annular body 10 are connected as a whole, conduction can also be achieved only through the supporting convex portions 11, or conduction can also be achieved through the annular body 10 itself. The present invention does not limit this and can be reasonably selected and set according to actual needs.

[0049] Such as Figures 4 to 6As shown, the present invention also discloses a pipe fitting connection structure 4, which includes a hoop 3 and the support member 1 in any of the above embodiments. The hoop 3 is used to tightly hold the pipe fittings 2 on both sides of the support member 1 at the docking place of the pipe fittings 2. The support member 1 is located inside the hoop 3 and is docked with the pipe fittings 2 on both sides of the support member 1. A sealing ring 5 is provided between the hoop 3 and the support member 1.

[0050] That is to say, the pipe fitting connection structure 4 is mainly composed of a hoop 3, a support member 1 and a sealing ring 5. Among them, the support member 1 is located in the innermost part. The support protrusion 11 on the support member 1 can extend into the pipe fittings 2 on both sides of the support member 1 along the axial direction of the annular main body 10 (such as Figure 4 and Figure 5 the A direction shown in the figure), and fits with the inner wall of the pipe fitting 2 to support the pipe fitting 2 from the inside. After the support member 1 is docked with the pipe fittings 2 on both sides, the sealing ring 5 is sleeved at the docking place of the pipe fittings 2, so that the sealing ring 5 completely covers the flange 12 and the outer wall 102 of the support part 1, realizing the sealing of the connection part of the pipe fittings 2. Then, the hoop 3 is installed outside the sealing ring 5, so that the hoop 3 completely covers the sealing ring 5. By tightly holding the pipe fittings 2 on both sides of the support member 1 and pressing the sealing ring 5 with the hoop 3, the effective and reliable docking and sealing of the pipe fittings 2 are realized. This pipe fitting connection structure 4 can not only support the pipe fitting 2 from the inside through the support member 1 to prevent the hoop 3 from squeezing and deforming the pipe fitting 2. At the same time, it can also realize the effective docking and reliable sealing of the connection part of the pipe fitting 2 through the combination of the hoop 3, the support member 1 and the sealing ring 5, improving the waterproof performance of the whole pipeline.

[0051] See Figures 4 to 6 As shown, in this embodiment, the hoop 3 includes at least two hoop segments 30. The end of the hoop segment 30 is provided with a connection part 300. The hoop segments 30 are sequentially connected through the connection part 300 to form a complete hoop 3. That is to say, the hoop 3 is composed of a plurality of hoop segments 30 connected in sequence. The present invention does not limit the number and specific structure of the hoop segments, and can be reasonably selected according to the shape, structure and size of the pipe fitting, as long as the hoop can tightly hold the sealing ring and the connection part of the pipe fitting.

[0052] Specifically, see Figures 4 to 6 As shown, in this embodiment, the hoop 3 is formed by connecting two hoop segments 30. Connection parts 300 are provided on both ends of each hoop segment 30. The two hoop segments 30 are relatively connected through the connection parts 300 to form a complete hoop 3. In this embodiment, the connection part 300 on the hoop segment 30 is a lug structure. When the two hoop segments 30 are relatively engaged, the corresponding connection parts 300 can also be docked, and then the docked connection parts 300 are locked through a locking member (such as a bolt, a screw, a pin, a rivet, etc.), so that the two hoop segments 30 form a complete hoop 3 surrounding the sealing ring. At the same time, the force of the hoop 3 holding the connection part of the pipe fitting 2 can be adjusted by adjusting the locking member, which is convenient for use.

[0053] In addition, for the convenience of docking and engaging the connection parts 300 docked on the adjacent hoop segments 30, refer to Figure 6 As shown, in this embodiment, a concave portion 302 is provided on the connection part 300 at one end of the hoop segment 30, and a convex portion 301 is provided on the connection part at the other end. The convex portion 301 on the hoop segment 30 engages with the concave portion 302 on the adjacent hoop segment 30, and an anti-fooling portion 31 is provided on the connection part 300 of the hoop segment 30. That is, by respectively providing the convex portion 301 and the concave portion 302 on the connection parts 300 at both ends of the hoop segment 30, the connection part 300 with the concave portion 302 on the hoop segment 30 can only be docked and engaged with the connection part 300 with the convex portion 301 on the adjacent hoop segment 30. At the same time, combined with the anti-fooling portion 31 provided on the connection part 300, the situation of incorrect connection of the hoop segment 30 is avoided, ensuring that the hoop segments 30 can be connected in sequence and orderly.

[0054] In another embodiment of the present invention, concave portions are provided on the connection parts at both ends of the hoop segment, convex portions are provided on the connection parts at both ends of the adjacent hoop segment, and the convex portion on the hoop segment engages with the concave portion on the adjacent hoop segment. That is, the concave portions are provided on the connection parts at both ends of the same hoop segment, the convex portions are provided on the connection parts at both ends of the adjacent hoop segment, and the hoop segments provided with convex portions and the hoop segments provided with concave portions are connected in sequence and orderly around the circumference of the pipe fitting to form a complete hoop. In other embodiments, the forms and specific numbers of the convex portions and the concave portions can be reasonably set and selected according to actual needs, and the present invention does not limit this, as long as the adjacent hoop segments can be effectively engaged and connected.

[0055] Refer to Figure 6 And in combination with Figure 4 As shown, in this embodiment, the anti-fooling portion 31 on the connection part 300 is a raised stripe. Specifically, two vertical raised stripes are provided on the outer side of the connection part 300 with the convex portion 301, and one vertical raised stripe is provided on the outer side of the connection part 300 with the concave portion 302. By identifying the number of the raised stripes, it is very convenient to identify which end of the hoop segment 30 the convex portion 301 and the concave portion 302 on the connection part 300 are located at, which is convenient for the installation and use of the hoop segment 30. In other embodiments, the anti-fooling portion can also be other structures, such as different numbers of convex points, patterns of different shapes, etc. The present invention does not limit this and can be reasonably set according to actual needs.

[0056] In summary, by adopting the technical solution provided by the present application and using the support member composed of the annular main body and the support protrusion, it is possible to support and seal the pipe fittings after the butt joint of the pipe fittings is completed, prevent the pipe fittings from deforming under the action of the fasteners, ensure that the adjacent pipe fittings on both sides of the support member can be effectively and reliably butted, and further improve the sealing performance and waterproof performance at the butt joint of the adjacent pipe fittings, making the pipe system formed by connecting the pipe fittings safer and more reliable.

[0057] In addition, it should be noted that the present invention does not limit the specific structure, type and use of the pipe fittings in the above embodiments, and can be reasonably selected according to actual needs, as long as it can be butted with the support member and the pipe fitting connection structure composed of the support member, the hoop and the sealing ring. Preferably, as shown in Figures 7 to 9 FIG. 5, the pipe fitting 2 is a pipe 6 applied to the pipeline layout of the power system.

[0058] Specifically, as shown in Figures 7 to 9 FIG. 6, the cross-section of the pipe 6 includes a closed contour 600 formed by the smooth connection of a first side 60, a second side 61, a third side 62 and a fourth side 63 in sequence. Among them, the first side 60 and the third side 62 are oppositely arranged in a first direction (such as the Z direction shown in Figures 7 to 9 FIG. 6), the second side 61 and the fourth side 63 are oppositely arranged in a second direction (such as the X direction shown in Figures 7 to 9 FIG. 6), the first direction and the second direction are perpendicular to each other, and among them, the second side 61 and the fourth side 63 are curves protruding outward from the contour 600.

[0059] That is to say, the contour 600 of the cross-section of the pipe 6 is mainly composed of the first side 60, the second side 61, the third side 62 and the fourth side 63. Each side can be connected by a node or by a connecting section. Specifically, in this embodiment, the contour 600 is a closed polygon formed by the smooth connection of each side in sequence, that is, each side is connected by a smooth connecting section in sequence. In this article, "smooth" means smooth and slippery, avoiding the formation of a fold angle between each side, which can well disperse the resultant force formed by the gravity and stress of the concrete, and improve the strength of the pipe 6. At the same time, each side of the contour 600 is also smooth, which is conducive to dispersing the force.

[0060] Specifically, as shown in Figures 7 to 9As shown, in this embodiment, the first side 60 and the third side 62 are oppositely arranged in the first direction, and the second side 61 and the fourth side 63 are oppositely arranged in the second direction. Among them, the first direction is the thickness direction of the wire tube 6, that is, the height direction of the wire tube 6, and the second direction is the width direction of the wire tube 6. Therefore, the first direction and the second direction are perpendicular to each other. That is to say, the first side 60 and the third side 62 are respectively the upper side and the lower side of the wire tube 6, and the second side 61 and the fourth side 63 are respectively the right side and the left side of the wire tube 6.

[0061] In other embodiments, the first direction and the second direction can be set according to the specific structure of the wire tube. The present invention does not limit this and can be reasonably selected according to actual needs. For example, the first direction and the second direction can also be set at a certain angle as long as the sides of the wire tube can be oppositely arranged and are easy to distinguish.

[0062] See Figures 7 to 9 As shown, in this embodiment, the second side 61 and the fourth side 63 of the wire tube 6 are curves protruding outward from the outer contour 600. That is to say, the second side 61 and the fourth side 63 of the wire tube 6 protrude outward in the second direction, so that the second side 61 and the fourth side 63 form a curved shape, and the second side 61 and the fourth side 63 are respectively smoothly connected to the first side 60 and the third side 62 in sequence.

[0063] When the first side 60 of the wire tube 6 bears the resultant force formed by the gravity and stress of the concrete, the first side 60 can transfer the force it bears to the second side 61 and the fourth side 63 with a curved shape through a smooth connection section, and can well disperse the force exerted by the concrete on the first side 60. In addition, since the second side 61 and the fourth side 63 are in a curved shape, while bearing the force transmitted from the first side 60, the second side 61 and the fourth side 63 are also subjected to the extrusion force exerted by the concrete on both sides. At the same time, since the second side 61 and the fourth side 63 protrude outward from the outer contour 600, the extrusion force is directed towards the inner side of the contour 600. The extrusion force can form a support for the second side 61 and the fourth side 63 in the radial direction of the second side 61 and the fourth side 63, thereby resisting the force transmitted from the first side 60, keeping the entire contour 600 of the wire tube 6 stable, avoiding deformation, eliminating the hidden danger of possible gaps between the wire tubes 6, and being able to effectively achieve the effects of waterproofing and preventing mud leakage, improving the waterproof performance and strength of the wire tube 6, and ensuring that the pipeline system arranged by the entire wire tube 6 is safer and more reliable.

[0064] Adopting the above technical solution, by smoothly connecting each side of the wire pipe in sequence and designing the second side and the fourth side as a curved shape protruding outward from the contour, it can not only well disperse and bear the resultant force exerted by the concrete, improve the strength and waterproof performance of the wire pipe, making the wire pipe safer and more reliable, but also designing the second side and the fourth side as a curved shape can make the pipeline better fit with the second side and the fourth side, improving the space utilization rate inside the wire pipe.

[0065] It should be noted that the present invention does not limit the specific shapes of the first side and the third side, and can be reasonably selected according to actual needs as long as it can ensure the strength, waterproof performance of the wire pipe and the space utilization rate inside the wire pipe.

[0066] Specifically, referring to Figures 7 to 8 As shown, in this embodiment, the first side 60 and the third side 62 are straight lines. By setting the first side 60 and the third side 62 as straight lines, not only can the wire pipe 6 be more simple in structure, facilitating production, transportation and installation while ensuring sufficient strength and waterproof performance, but also it can ensure that the wire pipe 6 has a high space utilization rate under certain height requirements.

[0067] Referring to Figure 9 As shown, in another embodiment of the present invention, the first side 60 and the third side 62 are curves protruding outward from the contour 600, and the curvature K1, K3 of the first side 60 and the third side 62 are less than 0.002, that is, the curvature K1, K3 at each point of the first side 60 and the third side 62 are less than 0.002. By also designing the first side 60 and the third side 62 as curves protruding outward from the contour 600, not only can the sides of the wire pipe 6 be more smoothly connected, better disperse and bear the force exerted by the concrete and ensure that the wire pipe 6 has sufficient strength and waterproof performance, but also it can increase the space inside the wire pipe 6, improving the wire threading capacity and space utilization rate of the wire pipe 6. In addition, limiting the curvature K1, K3 at each point of the first side 60 and the third side 62 within the range less than 0.002 can limit the bending degree of the first side 60 and the third side 62, ensuring that the height of the wire pipe 6 remains within an effective use range.

[0068] It should be further noted that the present invention does not limit the specific shapes of the second side and the fourth side, and can be reasonably selected according to actual needs as long as it can ensure the strength, waterproof performance of the wire pipe and the space utilization rate inside the wire pipe.

[0069] Specifically, in the present invention, both the second side 61 and the fourth side 63 include any one or any combination of an arc, an elliptical arc, a parabolic segment, an involute segment, and a spiral segment. In this embodiment, the second side 61 and the fourth side 63 have the same shape, which can make the force on the wire tube 6 symmetrically distributed. Preferably, both the second side 61 and the fourth side 63 are elliptical arcs. In other embodiments, the second side and the fourth side may also be other shapes, and the present invention does not limit this.

[0070] Furthermore, referring to Figure 9 As shown, in this embodiment, the curvature K2 and K4 of the second side 61 and the fourth side 63 range from 0.01 to 0.05. That is, the curvature K2 and K4 at each point of the second side 61 and the fourth side 63 both range from 0.01 to 0.05. When the curvature K2 and K4 of the second side 61 and the fourth side 63 are larger, the second side 61 and the fourth side 63 will bulge more towards the outside of the contour 600, making the shapes of the second side 61 and the fourth side 63 become flatter, and pipelines cannot be effectively arranged on both sides, reducing the space utilization rate inside the wire tube 6. When the curvature K2 and K4 of the second side 61 and the fourth side 63 are smaller, the second side 61 and the fourth side 63 will become straighter, increasing the smooth transition between the second side 61 and the fourth side 63 and the first side 60 and the third side 62, and unable to effectively disperse and bear the force exerted by the concrete, reducing the strength and waterproof performance of the wire tube 6. Therefore, preferably, the curvature K2 and K4 of the second side 61 and the fourth side 63 range from 0.01 to 0.05. By limiting the bending degree of the second side 61 and the fourth side 63, the wire tube 6 can effectively disperse the force exerted by the concrete, avoid deformation of the wire tube 6, and further ensure that the wire tube 6 has high strength and good waterproof performance while ensuring a high space utilization rate inside the wire tube 6.

[0071] During the actual use process, there are certain limitations on the thickness of the poured concrete and the size of the steel bar framework structure. Generally, the thickness of the concrete is between 80 mm and 150 mm. Therefore, it is necessary to limit the size of the wire tube to ensure that the wire tube can be completely poured into the concrete and the steel bar framework structure.

[0072] Specifically, referring to Figures 8 to 9As shown, in this embodiment, the distance L1 between the first side 60 and the third side 62 is 25 mm to 45 mm, that is, the maximum distance L1 between the first side 60 and the third side 62 is 25 mm to 45 mm. The distance L2 between the second side 61 and the fourth side 63 ranges from 50 mm to 300 mm, that is, the maximum distance L2 between the second side 61 and the fourth side 63 ranges from 50 mm to 300 mm. By restricting the size of the wire conduit 6, the wire conduit 6 can be completely cast in the concrete and the steel frame structure, preventing the wire conduit 6 from protruding from the concrete and the steel frame structure.

[0073] In addition, to keep a high space utilization rate inside the wire conduit, refer to Figures 8 to 9 As shown, in this embodiment, the ratio range of the distance between the first side 60 and the third side 62 to the distance between the second side 61 and the fourth side 63 is 0.1 to 0.7. That is to say, the wire conduit 6 needs to conform to a certain ratio range in the height direction and the width direction. Preferably, this ratio range is 0.1 to 0.7, that is, the range of L1 / L2 is 0.1 to 0.7. If the ratio of the height to the width of the wire conduit 6 is small, the lengths of the first side 60 and the third side 62 of the wire conduit 6 will be too long, and its ability to bear the concrete pressure will be reduced, and deformation is likely to occur. If the ratio of the height to the width of the wire conduit 6 is large, the lengths of the second side 61 and the fourth side 63 of the wire conduit 6 will be too long, increasing the height of the wire conduit 6, which cannot ensure that the wire conduit 6 can be completely cast in the concrete, and reduces the space utilization rate inside the wire conduit 6. In this embodiment, by limiting the range of L1 / L2 between 0.1 and 0.7, the space utilization rate inside the wire conduit 6 can be improved on the premise of ensuring the strength of the wire conduit 6.

[0074] Refer to Figures 7 to 9 As shown, in this embodiment, the wire conduit 6 is integrally formed from an aluminum alloy material. By integrally forming the aluminum alloy material into a wire conduit, not only can the sealing performance of the overall structure of the wire conduit 6 be ensured, improving the waterproof performance of the wire conduit 6, but also the aluminum alloy material can make the wire conduit have a better anti-corrosion effect, increasing the service life of the wire conduit. Moreover, the aluminum alloy material is easy to form and convenient for processing and manufacturing. At the same time, the aluminum alloy material can conduct electricity and can be used as the grounding wire of the pipeline system, eliminating the need to separately set up grounding terminals and grounding wires in the pipeline system, simplifying the structure of the pipeline system.
