[0033] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] Example 1

[0035] like Figures 1-6 As shown in this embodiment, a secondary structure dense PVC pre-reserved conduit fixing device includes a supporting angle steel, a fastening mechanism, a U-shaped connecting plate 2, multiple metal pipes 3, and positioning bolts 4. The supporting angle steel includes a first connecting plate 1 and a second connecting plate 11 integrally connected vertically into an L-shape. The fastening mechanism penetrates the first connecting plate 1 vertically and is threadedly connected to the first connecting plate 1. The two ends of the U-shaped connecting plate 2 are respectively vertically connected to the outer surface of the second connecting plate 11. The bottom plate 21 of the U-shaped connecting plate 2 is arranged parallel to and spaced apart from the second connecting plate 11. Multiple metal pipes 3 are placed in the gap between the bottom plate 21 and the second connecting plate 11. The outer wall of the metal pipe 3 is slidably connected to the second connecting plate 11 and the bottom plate 21 through a first sliding support 31 and a second sliding support 32, respectively. Multiple positioning bolts 4 are threadedly connected to the peripheral side end face of the bottom plate 21. The positioning bolts 4 can abut against the second sliding support 32 and are inserted and limited within the second sliding support 32.

[0036] like Figures 1-6 As shown, in a preferred embodiment, the first sliding support 31 and the second sliding support 32 are both plate-shaped structures, and the plate-shaped structures are arranged perpendicular to the central axis of the metal tube 3.

[0037] like Figure 6 As shown, specifically, in this embodiment, the first sliding support 31 and the second sliding support 32 are arranged opposite each other along the radial direction of the metal tube 3.

[0038] Preferably, each metal pipe 3 can correspond to a threaded hole. The spacing between adjacent threaded holes can be determined according to the electrical piping requirements of the building unit, the number of sleeves and the arrangement density can be determined, and the axial spacing of adjacent PVC conduits can be completely coincided with the positioning reference of the metal pipe. After the spacing of the metal pipe is adjusted, the position of the metal pipe after movement can be fixed by positioning bolts, ensuring geometric alignment control throughout the entire on-site installation process.

[0039] In this embodiment, the supporting angle steel serves as the fundamental support component of the entire structure. Made of high-quality steel, it possesses high strength and rigidity. The L-shaped cross-section of the supporting angle steel provides a stable support surface, ensuring the stability of the entire fixing device during movement. The supporting angle steel is fixed to the secondary structure's inverted retaining wall template via a tightening mechanism, providing a reliable installation foundation for other components.

[0040] The secondary structure dense PVC pre-reserved conduit fixing device of this embodiment can realize the geometric alignment control of the entire process of pipeline prefabrication and installation in the secondary structure retaining wall area, which significantly improves the load-bearing stability of the dense pipeline group in the retaining wall area. Compared with the traditional wire binding process, this device has the advantages of high positioning accuracy, strong load-bearing capacity, high construction efficiency, and fewer common quality defects, effectively solving problems such as large pipeline positioning deviation and high wire pulling resistance.

[0041] This embodiment of the secondary structure dense PVC pre-reserved conduit fixing device can construct a standardized conduit bundle system through parametric design and CNC welding technology, achieving precise three-dimensional spatial alignment and completely solving the rework problem caused by conduit misalignment in traditional processes. Its truss-like mechanical structure combined with the rigid constraint of galvanized steel sleeves ensures uniform stress distribution, improved load-bearing capacity, and effective resistance to concrete pouring impact, preventing conduit collapse and deformation. The guide rail groove design for moving metal pipes allows for flexible adjustment of conduit spacing, and the smooth inner wall of the metal pipe significantly reduces conduit insertion resistance, solving the problems of wire damage and difficult wiring. This device breaks through the limitations of traditional processes, reconstructing technical standards in terms of positioning accuracy, structural strength, and construction efficiency, providing an efficient and reliable solution for building electromechanical installation.

[0042] Example 2

[0043] Based on Example 1, this example provides a sliding connection structure for a metal tube. For example, 1. Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the base plate 21 has an elongated adjustment hole 22, which is arranged parallel to the corner line of the supporting angle steel. A guide rail groove 12 is provided on the outer surface of the second connecting plate 11, which is arranged opposite to and parallel to the adjustment hole 22. The first sliding support 31 is slidably connected within the guide rail groove 12, and the second sliding support 32 is slidably connected within the adjustment hole 22. The positioning bolt 4 extends into the adjustment hole 22. By providing the adjustment hole and guide rail groove, the metal tube can be moved along the base plate, facilitating the adjustment of the metal tube's position.

[0044] like Figure 1 , Figure 2 and Figure 6 As shown, preferably, the positioning bolt 4 is arranged perpendicular to the extension direction of the adjusting hole 22.

[0045] like Figure 6 As shown, in a preferred embodiment, the guide rail groove 12 is a dovetail groove, and the first sliding support 31 is slidably connected to one end of the guide rail groove 12 in a dovetail shape. The dovetail groove design prevents the first sliding support from dislodging from the guide rail groove. A dovetail groove guide rail is a commonly used type of precision guide rail, with a dovetail-shaped cross-section that is narrower at the top and wider at the bottom, forming an embedded fit with the tenon of the first sliding support.

[0046] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in a preferred embodiment, the second sliding support 32 passes through the adjustment hole 22. This facilitates the sliding of the second sliding support within the adjustment hole, making it easier to adjust the position of the metal tube within the U-shaped connecting plate.

[0047] like Figure 6 As shown, the bottom plate 21 has multiple threaded holes on its peripheral side end face that communicate with the adjustment hole 22, and the second sliding support 32 of each metal tube 3 is arranged corresponding to one or more threaded holes.

[0048] In this embodiment, the metal tube can be made of galvanized steel, and the inner diameter of the metal tube can be selected from 20mm to 40mm, possessing high strength and wear resistance. The inner diameter of the metal tube in this embodiment matches that of the PVC pipe. The metal tube can move along the guide groove and adjustment hole. After being moved to the corresponding position, the rotating positioning bolt is used to position itself by abutting downwards against the second sliding support, or by passing through the second sliding support, thereby achieving precise position adjustment.

[0049] In this embodiment, the positioning bolt, as a connecting component, is made of high-quality steel and possesses high strength and toughness. The positioning bolt is used to fix the metal pipe in position, ensuring that the metal pipe cannot move arbitrarily.

[0050] In this embodiment, the U-shaped connecting plate can be made of channel steel. Adjustment holes parallel to the guide rail groove can be precisely cut into the bottom plate of the U-shaped connecting plate to form a dedicated trajectory for the movement of the metal tube. This embodiment can ensure the geometric consistency between the adjustment holes and the guide rail groove through high-precision CNC technology, optimize the movement path of the metal tube, and, in conjunction with the rigidity of the metal tube, achieve flexible adjustment and precise positioning of the pipeline layout.

[0051] Example 3

[0052] Based on Embodiment 1 or Embodiment 2, this embodiment provides a specific structure for a locking mechanism. For example... Figure 1 , Figure 2 , Figures 4-6As shown, the first connecting plate 1 in this embodiment has a through hole, and a set nut 51 is fixed to the first connecting plate 1 at the position of the through hole. The fastening mechanism includes a lead screw 5 and a metal washer 52. The lead screw 5 passes through the through hole and is threadedly connected to the set nut 51. The metal washer 52 is fixed to one end of the lead screw 5 near the second connecting plate 11. By setting the lead screw and the metal washer, the metal washer can be supported at the position that needs support by rotating the lead screw, so that the entire device can be stably supported.

[0053] like Figures 1-6 As shown, preferably, the other end of the lead screw 5 is provided with a handle 53. By providing a handle, it is convenient to operate the handle and rotate the lead screw.

[0054] In this embodiment, the lead screw can be 12mm in diameter. As a precision transmission component, the lead screw is made of high-strength alloy steel with a precision-machined surface and high-precision threads. The set nut is used in conjunction with the lead screw and has a matching thread specification. The set nut is fixed to the first connecting plate. When the lead screw rotates, it moves axially up and down. A handle is fixed to the upper end of the lead screw for easy rotation by the operator. By rotating the lead screw, the metal washer below it can reliably contact the template wood, increasing the contact area and ensuring the stability of the entire fixing device. This fixing method is not only simple in structure and easy to operate, but also ensures that the entire system remains stable and accurate during movement.

[0055] This embodiment innovatively adopts a combination design of supporting angle steel, guide rail groove and screw rod, which can optimize the layout of support and hanging nodes through mechanical simulation, and significantly improve the load-bearing stability of the dense pipeline group in the reverse slope area.
