Description

Technical Field

[0001] The utility model relates to the technical field of building electrical construction, in particular to a building electrical pipeline system passing through an earthquake-resistant joint. Background Art

[0002] Building electrical construction technology is a construction technology that uses buildings as a platform to artificially create a humanized living environment in a limited space. Modern buildings tend to be diversified in design, so pouring electrical construction is also facing greater challenges. In order to avoid the destruction of buildings, seismic joints must be set according to seismic requirements when the buildings are constructed. Seismic joints are generally set at sensitive locations of structural deformation and are fully set along the top surface of the house foundation. The structures on both sides of the seismic joints are completely separated, and the gap distance in the middle ensures that the structures on both sides do not collide under the action of an earthquake.

[0003] Application No. CN202122543097.9 discloses a building electrical pipeline system passing through an anti-seismic joint, which belongs to the field of building electrical construction technology, and includes a support mechanism fixedly connected to the building structure. A set of support mechanisms are provided on the building structures on both sides of the anti-seismic joint. The wires pass through the two sets of support mechanisms in turn, and the wires are retained in the support mechanisms. The wires located between the two sets of support mechanisms are arranged in an arc shape. This application has the effect of reducing the situation in which the electrical pipelines are broken due to the shaking of the building structures on both sides of the anti-seismic joint, thereby causing the interruption of power supply. However, the drooping part in this application is exposed to the outside, and it is easy to be broken by falling rocks without a protective structure in the event of an earthquake. The electrical pipelines passing through the anti-seismic joint are fixed to the building structures on both sides of the gap. When an earthquake occurs, the building structures on both sides of the anti-seismic joint shake, causing the electrical pipelines to break, thereby causing the interruption of power supply.

[0004] How to solve the above problems is the research focus of this program. Utility Model Content

[0030] Example 1

[0031] See also Figures 1 to 4 The utility model provides a building electrical pipeline system passing through an earthquake-resistant joint, including a wall surface 100, a junction box housing 200, a fixing plate 300, a second fixing plate 400, a tension spring 500 and a protection plate 600.

[0032] A seismic joint 110 is formed on the side wall of the wall 100 .

[0033] There are two junction box shells 200 and they are respectively located on both sides of the seismic joint 110. An inner cavity is opened inside the junction box shell 200. Wire holes 210 are opened on the symmetrical side walls of the junction box shell 200. The wire holes 210 are connected to the inner cavity. The line extends into the inner cavity of the junction box shell 200 through the wire holes 210 and extends out from the wire holes 210 on the other side wall of the junction box shell 200. A fixing plate 220 is provided on the side wall of the junction box shell 200 facing the wall 100. A plurality of screw holes 230 are opened on the side wall of the fixing plate 220. The screw holes 230 are consistent with the common screw caliber, so that the screws can pass through the screw holes 230 to fix the junction box shell 200 to the side wall of the wall 100. Guide grooves 240 are opened on the symmetrical side walls of the junction box shell 200. The guide grooves 240 can guide and limit the guide blocks 620, limit the protection plate 600 above the junction box shell 200, and improve the stability of the protection plate 600 when it moves vertically.

[0034] The fixing plate 300 is arranged on one of the side walls of the junction box shell 200, and a second wire hole 310 is opened on the side wall of the fixing plate 300. A fixing column 320 is arranged on the side wall of the fixing plate 300, and a slide groove 330 is opened on the side wall of the fixing column 320. The slide groove 330 is connected with the second wire hole 310, and the line passes through the second wire hole 310 into the slide groove 330 and hangs down inside the slide groove 330.

[0035] The second fixing plate 400 is arranged on the side wall of another junction box housing 200, and a third wire hole 410 is opened on the side wall of the second fixing plate 400. A sliding column 420 is arranged on the side wall of the second fixing plate 400, and a second slide groove 430 is opened on the side wall of the sliding column 420. The sliding column 420 is located inside the slide groove 330, and the sliding column 420 slides and matches with the slide groove 330. A piston 440 is arranged on the end of the sliding column 420 away from the second fixing plate 400, and the piston 440 is located inside the slide groove 330. A fourth wire hole 450 is opened on the side wall of the piston 440, and an air hole 460 is also opened on the side wall of the piston 440. The air holes 460 are multiple and evenly spaced. The fourth wire hole 450 is evenly surrounded by the outside, and the fourth wire hole 450 and the air hole 460 are connected with the sliding column 420. The line passes through the fourth wire hole 450 and extends into the second slide groove 430, and passes through the third wire hole 410 and extends into the inner cavity of another junction box shell 200. When an earthquake occurs, the two junction box shells 200 move away from each other, driving the second slide groove 430 and the piston 440 to slide inside the slide groove 330. When the piston 440 slides, the air inside the sliding column 420 flows through the air hole 460 and the fourth wire hole 450, and the friction of the air is used to neutralize the pulling force generated by the two junction box shells 200 moving away from each other, thereby playing a buffering role.

[0036] Two ends of the tension spring 500 are respectively connected to the side wall of the fixing plate 300 and the side wall of the second fixing plate 400. When the two junction box housings 200 move away from each other, the tension spring 500 buffers the pulling force generated by the two junction box housings 200 moving away from each other.

[0037] Side panels 610 are symmetrically arranged at both ends of the protection plate 600, and guide blocks 620 are arranged inside the side walls of the side panels 610. The guide blocks 620 are located inside the guide grooves 240, and the guide blocks 620 are slidably connected to the guide grooves 240. A spring 630 is arranged at the bottom of the protection plate 600, and the bottom of the spring 630 is connected to the top of the junction box housing 200. The protection plate 600 protects the top of the junction box housing 200. When falling rocks hit the top of the protection plate 600, the protection plate 600 slides downward to squeeze the spring 630. The spring 630 buffers the downward force of the protection plate 600 to prevent falling rocks from directly hitting the junction box housing 200 and causing damage to the junction box housing 200.

[0038] During use, screws are inserted through the screw holes 230 to install the two junction box housings 200 on both sides of the seismic joint 110, the sliding column 420 and the piston 440 are located inside the slide groove 330, and the wires are respectively inserted through the two junction box housings 200 with the drooping parts located inside the slide groove 330. When an earthquake occurs, the two junction box housings 200 move away from each other, pulling the sliding column 420 and the piston 440 to move inside the slide groove 330. The air inside the sliding column 420 passes through the fourth wire hole 450 and the air hole 460, and the air friction force and the tensile force of the tension spring 500 are used to neutralize and buffer the tension generated when the two junction box housings 200 move away from each other. At the same time, the fixed column 320 and the sliding column 420 can protect the wires to prevent falling rocks from hitting the lines and causing damage to the lines.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
