Abstract
Description
Technical Field

[0002] During building design, expansion joints are installed to account for thermal expansion, settlement deformation, and earthquakes, preventing cracks or even damage to the building structure. Common expansion joints include expansion joints, settlement joints, and seismic joints. Seismic joints are designed to improve a building's earthquake resistance and reduce the destructive power of earthquakes.
[0003] During construction, electrical pipelines are installed across seismic joints. Existing electrical pipeline installation structures include junction boxes, which are fixedly installed on opposite sides of the building where the joint is located. Electrical pipelines are electrically connected between the two junction boxes. These pipelines adapt to the deformation of the seismic joint and ensure electrical connectivity between the two buildings.
[0004] However, because electrical pipelines are exposed in seismic joints, some accumulated water can easily seep into the joints from the building walls and drip into the electrical pipelines. Over time, the accumulated water that drips into the electrical pipelines will corrode the pipelines, shortening their service life. Utility Model Content

[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] See also Figure 1 A building electrical pipeline system for passing through a seismic joint includes two buildings 1 with a seismic joint 2 defined between them. Junction boxes 3 are fixedly mounted on the bottom surfaces of the two buildings 1. A pre-buried junction box 4 is fixedly connected to the top surface of the junction boxes 3 and is pre-buried within the buildings 1. Electrical pipelines 5 are electrically connected between the two junction boxes 3. A telescopic protective box 6 is also mounted between the two junction boxes 3 to house and protect the electrical pipelines 5. A fixing assembly is mounted on the junction boxes 3 to secure the telescopic protective box 6 between the two junction boxes 3.
[0033] During the construction of the seismic joint 2, the pre-embedded junction box 4 is first embedded and fixed within the building 1, while the junction box 3 is exposed on the bottom surface of the building 1. The two junction boxes 3 are then electrically connected to the electrical pipeline 5. A telescopic protective box 6 is then installed to protect the electrical pipeline 5 and secured to the telescopic protective box 6 with a fixing assembly. The telescopic protective box 6 adaptively expands and contracts according to the changes in the seismic joint 2, thus protecting the electrical pipeline 5.
[0034] See also Figure 1 and Figure 2 To facilitate the installation of protective electrical lines 5 in the telescopic protective box 6, the top surface of the telescopic protective box 6 is open. Guide bars 7 are fixedly connected to the opposite sides of the two junction boxes 3. Guide grooves 8 are formed at the ends of the telescopic protective box 6 corresponding to the positions of the guide bars 7. The guide bars 7 are slidably connected to the guide grooves 8.
[0035] When it is necessary to cover and protect the electrical pipeline 5, first align the guide groove 8 of the telescopic protection box 6 with the guide bar 7, and then slide the telescopic protection box 6 through the guide groove 8 and the guide bar 7. At this time, the telescopic protection box 6 covers and protects the electrical pipeline.
[0036] For details, see Figure 1 and Figure 3The fixing assembly includes a rod 9. A socket 10 is fixedly connected to the bottom of the junction box 3. Fixing bases 11 are fixedly connected to both sides of the bottom of the telescopic protective box 6. The rod 9 slides and rotates within the fixing bases 11, with one end of the rod 9 extending outside the fixing base 11. One end of the rod 9 is plugged into the socket 10.
[0037] In addition, to cooperate with the movement of the insertion rod 9, the fixing seat 11 is equipped with an elastic member, which is a spring 12. The spring 12 is installed in the fixing seat 11, and the spring 12 is sleeved on the insertion rod 9, and one end of the spring 12 is fixedly connected to the side wall of the insertion rod 9, and the other end of the spring 12 is fixedly connected to the inner wall of the fixing seat 11.
[0038] When the rod 9 is driven to move away from the socket 10, the rod 9 compresses the spring 12. When the rod 9 is aligned with the socket 10 and the rod 9 is released, the spring 12 releases its elastic force and drives the rod 9 to be inserted into the socket 10. At this time, the telescopic protective box 6 is fixed between the two junction boxes 3.
[0039] See also Figure 3 In order to facilitate closing the open end of the telescopic protective box 6, a telescopic cover plate 13 is slidably installed on the open end of the telescopic protective box 6. The two opposite inner sides of the open end of the telescopic protective box 6 are fixedly connected with a sliding rib 14, and the telescopic cover plate 13 is slidably connected to the sliding rib 14.
[0040] The telescopic protective box 6 is also equipped with fixings for securing the telescopic cover 13. These fixings are bolts 15. Fixing ears 16 are fixedly connected to both sides of the telescopic cover 13. The fixing ears 16 fit closely to the telescopic protective box 6. The bolts 15 pass through the fixing ears 16 and are threadedly connected to the telescopic protective box 6.
[0041] To close the open end of the telescopic protective box 6, align the telescopic cover 13 with the sliding bar 14 and insert it into the open end. Once the fixing ears 16 are in contact with the sliding bar 14, tighten the bolts 15. The telescopic cover 13 is now closed and secured to the open end of the telescopic protective box 6. If the seismic joint 2 contracts, the telescopic cover 13 automatically adjusts its elasticity.
[0042] It is worth mentioning that see Figure 3 Sealing strips 17 are fixedly connected to both ends of the telescopic cover 13. When the telescopic cover 13 is slidably connected to the sliding ribs 14, the telescopic cover 13 is pressed against the inner wall of the telescopic protective box 6 through the sealing strips 17. Under the action of the sealing strips 17, the sealing of the connection between the telescopic cover 13 and the telescopic protective box 6 is improved.
[0043] See also Figure 1 A steel pipe 18 is buried in the building 1. A cable 19 is passed through the steel pipe 18, and the cable 19 is electrically connected to the junction box 3.
[0044] The cable 19 is arranged through the steel pipe 18, which is beneficial to prevent the cable 19 from being corroded by the cement.
[0045] Referring to Figure 1 The upper part of the anti-seismic joint 2 is covered by a cover 20, and the two ends of the cover 20 are fixedly connected with the top surface of the building body 1.
[0046] The anti-seismic joint 2 is covered by the cover 20, which is beneficial to reduce the rainwater flowing into the anti-seismic joint 2.
[0047] It should be noted that the electrical pipeline 5 comprises a metal hose 21 and a cross grounding wire 22. The metal hose 21 is connected between the two junction boxes 3. The cross grounding wire 22 is arranged around the metal hose 21, and the two ends of the cross grounding wire 22 are fixedly connected with the two junction boxes 3.
[0048] Working principle of the building electrical pipeline system through the anti-seismic joint:
[0049] During the construction of the anti-seismic joint 2, first, the embedded junction box 4 is embedded and fixed in the building body 1, and the junction box 3 is exposed on the bottom surface of the building body 1. Then, the electrical pipeline 5 is electrically connected between the two junction boxes 3. Then, the guide groove 8 of the telescopic protective box 6 is aligned with the guide strip 7, and then the telescopic protective box 6 is slidably connected with the guide strip 7 through the guide groove 8. Then, the telescopic protective box 6 is fixed between the two junction boxes 3 through the plug connection of the plug rod 9 and the socket 10. Finally, the telescopic cover plate 13 is fixed on the open end of the telescopic protective box 6 through the bolt 15, and the protection of the electrical pipeline 5 is completed.
[0050] As described above, under the protection of the telescopic protective box 6, the electrical pipeline 5 is prevented from being corroded by the water seepage, which is beneficial to improve the service life of the electrical pipeline 5 system.
[0051] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
