Description

Technical Field

[0001] This invention relates to the field of building technology, and specifically to a protective structure for a ground junction box and its construction method. Background Technology

[0002] In existing technologies, finished junction boxes are usually pre-buried in the ground. The top of the junction box is a metal cover that can be opened and closed to facilitate the inspection and maintenance of the wires inside the junction box. The metal cover is exposed on the ground surface. In public areas with passing vehicles, the metal cover is easily deformed by pressure, which can damage the junction box and shorten its service life. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a protective structure for ground junction boxes and its construction method to solve the problem that the metal cover of existing underground junction boxes is easily damaged by pressure.

[0004] To achieve the above objectives, the present invention provides a protective structure for a ground junction box, embedded within the road surface structure, the protective structure comprising:

[0005] A box for installation on the road surface structure, wherein the box has an internal space for accommodating a junction box, and the top surface of the box is open;

[0006] A tray is horizontally fixed above the box body. The tray has an inspection hole penetrating the tray and communicating with the accommodating space. The top surface of the road structure is higher than the top surface of the tray. The road structure has a mounting hole at the tray that communicates with the inspection hole.

[0007] A stone slab is placed on the support plate and located in the mounting hole. A gap is formed between the wall of the mounting hole and the stone slab to allow the stone slab to be pried open. The top surface of the stone slab is flush with the top surface of the road structure.

[0008] A limiting plate is horizontally fixed on the support plate. The limiting plate is provided with a limiting hole adapted to the stone slab for inserting the stone slab. The limiting hole is connected to the inspection hole. The support plate portion is located in the limiting hole to form a supporting part to support the stone slab.

[0009] A reinforcing plate is horizontally fixed on the support plate, and the reinforcing plate has a through hole penetrating the reinforcing plate;

[0010] The limiting plate is fixed horizontally on the reinforcing plate, the through hole communicates with the limiting hole and the inspection hole, and the reinforcing plate part is located in the limiting hole to form a bearing part to support the stone slab;

[0011] It also includes a stainless steel plate fixed under the stone slab, the cross-sectional dimensions of which are the same as those of the stone slab.

[0012] This invention involves installing a box housing a junction box with a support plate on top to support a stone slab. Installation holes are provided during road construction, and the stone slab is installed inside these holes to cover the inspection holes. Because a hard stone slab is used, it is less prone to deformation under pressure, resulting in a longer service life. When opening the stone slab, tools are inserted into the gap between the hole wall and the stone slab to pry it open, facilitating easy access for inspection. The junction box is further protected by the box housing, support plate, and stone slab, preventing damage caused by the junction box being exposed on the ground.

[0013] A further improvement to the protective structure of the ground junction box of the present invention is that it also includes a stainless steel sleeve that is fitted and fixed to the outside of the stone slab.

[0014] A further improvement to the protective structure of the ground junction box of the present invention is that it also includes a positioning plate fixed on the support plate. The positioning plate is provided with a positioning hole adapted to the stone slab for inserting the stone slab. The positioning hole communicates with the inspection hole. The support plate portion is located in the positioning hole to form a support portion.

[0015] The bottom surface of the stainless steel sleeve and the bottom surface of the stainless steel plate have a gap, the length of which is equal to the thickness of the positioning plate;

[0016] The stainless steel plate is placed on the support and its side abuts against the inner wall of the positioning hole, and the stainless steel is sleeved on the positioning plate.

[0017] A further improvement to the protective structure of the ground junction box of the present invention is that it also includes a baffle that is vertically fixed to the support plate along the wall of the mounting hole.

[0018] A further improvement to the protective structure of the ground junction box of the present invention is that the bottom surface of the box is open, and the bottom end of the box is bent outward to form a horizontally arranged folded edge, which is fixed to the construction surface by fasteners.

[0019] The present invention also provides a construction method for using the protective structure of the ground junction box as described above, comprising the following steps:

[0020] The junction box is fixed to the construction surface according to its designed location, and the junction box is installed inside the junction box.

[0021] The tray is fixed horizontally to the top surface of the box, and the inspection hole on the tray is connected to the accommodating space.

[0022] The road surface structure is constructed on the construction surface and the box body is embedded, so that the top surface of the road surface structure is higher than the top surface of the support plate, and the road surface structure has an installation hole at the support plate that communicates with the inspection hole.

[0023] The stone slab is placed on the support plate and located in the mounting hole, so that a gap is formed between the wall of the mounting hole and the stone slab, and the top surface of the stone slab is flush with the top surface of the road structure.

[0024] A further improvement to the construction method of the protective structure of the ground junction box of the present invention is that, after the support plate is installed, a limiting plate is provided. The provided limiting plate is provided with a limiting hole adapted to the stone slab. The limiting plate is horizontally fixed on the support plate, so that the limiting hole is connected to and aligned with the inspection hole, and the support plate part is located in the limiting hole to form a supporting part to support the stone slab.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0029] This invention provides a protective structure for a ground junction box and its construction method, including a box body, a support plate, a stone slab, a limiting plate, a stainless steel plate, and a stainless steel sleeve. The stone slab is made of high-hardness material, which is not easily deformed under pressure and is more robust and durable. The limiting plate limits the stone slab to prevent it from moving or misaligning, ensuring that the stone slab tightly covers the inspection hole.

[0030] The protective structure and construction method of the ground junction box of the present invention will be described below with reference to the accompanying drawings.

[0031] See Figure 1 In this embodiment, a protective structure for a ground junction box is embedded in a road structure 10. The protective structure includes: a box body 30 embedded in the road structure 10, the box body 30 having an internal accommodating space 31 for accommodating a junction box 20, and the top surface of the box body 30 being open; a support plate 40 horizontally fixed above the box body 30, the support plate 40 having an inspection hole 41 penetrating through the support plate 40, the inspection hole 41 communicating with the accommodating space 31, the top surface of the road structure 10 being higher than the top surface of the support plate 40, and the road structure 10 having an installation hole at the support plate 40 communicating with the inspection hole 41; a stone slab 50 covering the support plate 40 and located within the installation hole, a gap being formed between the hole wall of the installation hole and the stone slab 50 to allow the stone slab 50 to be pried open, and the top surface of the stone slab 50 being flush with the top surface of the road structure 10.

[0032] In this embodiment, the protective structure utilizes the box body 30, the support plate 40, and the stone slab 50 to form a protective structure covering the junction box 20, isolating the junction box 20 from the external environment, preventing the junction box 20 from being crushed by vehicles and corroded by rainwater, thus strengthening the protection of the junction box 20. The use of the hard stone slab 50 as the cover plate of the protective structure can withstand a large load, ensuring that the stone slab 50 will not deform or be damaged under pressure, making it more robust and durable.

[0033] See Figure 1 In one specific embodiment, the protective structure further includes a limiting plate 60 that is laterally fixed on the support plate 40. The limiting plate 60 is provided with a limiting hole 61 that is adapted to the stone slab 50 for inserting the stone slab 50. The limiting hole 61 is connected to and aligned with the inspection hole 41. A portion of the support plate 40 is located in the limiting hole 61 to form a supporting part to support the stone slab 50.

[0034] The stone slab 50 is inserted into the limiting hole 61 and placed on the supporting part of the support plate 40. The limiting hole 61 on the limiting plate 60 limits the stone slab 50, preventing the stone slab 50 from moving or misaligning when it is rolled over by a vehicle. At the same time, it also limits the gap between the hole wall of the mounting hole and the stone slab 50, making it easier to pry open the stone slab 50.

[0035] See Figure 1Furthermore, the protective structure also includes a reinforcing plate 70 that is laterally fixed on the support plate 40, and the reinforcing plate 70 has a through hole 71 that penetrates the reinforcing plate 70; the limiting plate 60 is laterally fixed on the reinforcing plate 70, and the through hole 71 is connected to and aligned with the limiting hole 61 and the inspection hole 41. The reinforcing plate 70 is partially located in the limiting hole 61 to form a bearing portion to support the stone slab 50.

[0036] By setting a reinforcing plate 70 on the support plate 40 and combining them together, the overall load-bearing capacity is enhanced to support the stone slab 50 and the load from the stone slab 50.

[0037] See Figure 1 and Figure 2 Furthermore, the protective structure also includes a stainless steel plate 81 fixed under the stone slab 50, the cross-sectional dimensions of the stainless steel plate 81 being consistent with the cross-sectional dimensions of the stone slab 50.

[0038] See Figure 1 and Figure 2 Furthermore, the protective structure also includes a stainless steel sleeve 82 that is fitted and fixed to the outside of the stone slab 50.

[0039] Preferably, the stainless steel sleeve 82 and the stainless steel plate 81 are installed and fixed to the stone slab 50 by means of an adhesive material.

[0040] See Figure 2 In another preferred embodiment, the protective structure further includes a positioning plate 90 fixed on the support plate 40. The positioning plate 90 has a positioning hole 91 adapted to the stone slab 50 for inserting the stone slab 50. The positioning hole 91 communicates with the inspection hole 41. The support plate 40 is partially located in the positioning hole 91 to form a support portion. The bottom surface of the stainless steel sleeve 82 and the bottom surface of the stainless steel plate 81 have a gap, the length of which is equal to the thickness of the positioning plate 90. The stainless steel plate 81 is placed on the support portion and its side abuts against the inner wall of the positioning hole 91. The stainless steel sleeve 82 is placed on the positioning plate 90.

[0041] The support portion of the tray 40 and the positioning plate 90 form a stepped shape to position the stainless steel plate 81 and the stainless steel sleeve 82, which serves to limit the position and strengthen the seal. Since the bottom surface of the stainless steel sleeve 82 abuts against the positioning plate 90, it can prevent rainwater from seeping into the accommodating space 31 along the gap.

[0042] See Figure 1 and Figure 2 Furthermore, the protective structure also includes a baffle 42 that is vertically fixed to the support plate 40 along the wall of the mounting hole.

[0043] Preferably, the baffle 42 is vertically fixed on the support plate 40.

[0044] See Figure 1 and Figure 2 Furthermore, the bottom surface of the box body 30 is open, and the bottom end of the box body 30 is bent outward to form a horizontally arranged folded edge 32, which is fixed to the construction surface by fasteners.

The stone slab 50 is placed on top of the support plate 40 and located inside the mounting hole, so that a gap is formed between the hole wall of the mounting hole and the stone slab 50, and the top surface of the stone slab 50 is flush with the top surface of the road structure 10.

[0047] Preferably, the road structure 10 includes a cement mortar layer disposed on the construction surface and a stone slab 50 layer disposed on the cement mortar layer, wherein the top surface of the stone slab 50 layer is flush with the top surface of the stone slab 50, and the bottom surface of the limiting plate 60 is flush with the bottom surface of the stone slab 50 layer.
