DETAILED DESCRIPTION

[0023] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the utility model of an electrical concealed piping installation structure suitable for prefabricated building construction in conjunction with the accompanying drawings.

[0024] See also Figure 1-4 The utility model is a kind of electrical concealed piping installation structure suitable for prefabricated building construction, comprising a junction box 1, two groups of connection boxes 2 and two groups of connection blocks 3, a side of each connection box 2 close to the junction box 1 is fixedly connected to the outer surface of the junction box 1, each connection block 3 is clamped in the inside of the connection box 2, the outer surface of the junction box 1 is respectively provided with a prefabricated cement layer 8 and a cast-in-place cement layer 9, the inner wall of the cast-in-place cement layer 9 is fixedly installed with a first steel bar 10, the prefabricated cement layer 8 is cast before the electrical concealed piping is installed, and the cast-in-place cement layer 9 is cast after the electrical concealed piping is installed, so that the junction box 1 and other devices are embedded in the floor slab formed by the cement layer, so as to facilitate the use of the floor slab to assemble the building, and the installation of the first steel bar 10 increases the firmness of the floor slab.

[0025] A wiring tube 4 is fixedly installed on the inner wall of each connecting block 3, and the wiring tube 4 is composed of a tube body with different inner diameters. Three fixed blocks 11 are fixedly installed on the outer surface of the junction box 1. The interior of each fixed block 11 is slidably connected to a second steel bar 12. The outer surfaces of the three second steel bars 12 are jointly sleeved with an iron wire 13, and the second steel bars 12 are fixed by the iron wire 13. By providing the fixed blocks 11, the second steel bars 12 and the iron wire 13, the contact area between the device and the prefabricated cement layer 8 is increased, thereby ensuring the stability of the junction box 1.

[0026] A fixing spring 5 is fixedly installed on the inner wall of each connection box 2, a box cover 14 is clamped inside the junction box 1, and a solid column 15 is clamped inside each wiring tube 4. The installation of the box cover 14 and the solid column 15 plays a role in sealing the junction box 1 and the wiring tube 4, thereby avoiding cement from entering the inside of the junction box 1 and the wiring tube 4 during the cement pouring process, thereby ensuring the smoothness of the electrical concealed piping installation.

[0027] A wedge block 6 is fixedly installed at the bottom end of each fixed spring 5, and each wedge block 6 is clamped in the inside of the connecting block 3. A telescopic rod 18 is fixedly installed on the inner wall of each connecting box 2, and the telescopic end of each telescopic rod 18 is fixedly connected to the upper surface of the wedge block 6. The installation of the telescopic rod 18 plays a role in limiting the moving trajectory of the wedge block 6, thereby avoiding the phenomenon of the wedge block 6 deviating from the moving trajectory when moving, thereby ensuring the stability of the movement of the wedge block 6.

[0028] A concave block 16 is fixedly mounted on the upper surface of the box cover 14, and a handle 17 is movably hinged inside the concave block 16. The installation of the concave block 16 and the handle 17 makes it convenient for workers to open the box cover 14 during the installation of concealed electrical piping, thereby reducing the complexity of the workers' operation.

[0029] A pull rod 7 is fixedly installed on the upper surface of each wedge block 6, a connecting column 19 is fixedly installed on the top of each pull rod 7, and a pull ring 20 is rotatably connected inside each connecting column 19. The installation of the connecting column 19 and the pull ring 20 makes it convenient for workers to pull the pull rod 7, thereby reducing the complexity of the operation when the workers pull the pull rod 7.

[0030] Two groups of magnetic columns 21 are fixedly installed on the inner wall of each connection box 2, and a baffle 22 is clamped inside each connection box 2. Two groups of magnets 23 are fixedly installed on the bottom surface of each baffle 22. The bottom end of each magnet 23 is in contact with the top of the magnetic column 21. The attraction between the magnet 23 and the magnetic column 21 is utilized to clamp the baffle 22 inside the connection box 2, so as to avoid cement from entering the inside of the connection box 2 during pouring, and to avoid the phenomenon that the pull rod 7 cannot be pulled due to the solidification of cement.

[0031] The working principle of the utility model is as follows: first, the worker inserts the second steel bar 12 into the interior of the fixing block 11, and then uses the iron wire 13 to fix the second steel bars 12 in pairs, so as to ensure the stability of the second steel bars 12, and then the worker uses the solid column 15 to seal the wiring tube 4, and uses the box cover 14 to seal the wiring box 1, and then the worker pours the prefabricated cement layer 8 on the outer surface of the wiring box 1 to solidify it, and when the prefabricated cement layer 8 is completely solidified, it is transported to the construction site for building splicing, and then the worker removes the box cover 14 and the solid column 15, and installs the electrical concealed piping. During the installation process, when it is necessary to install electrical concealed piping of different diameters, the worker first removes the corresponding baffle 22, and then the worker pulls the pull ring 20 upwards so that the pull ring 20 The connecting column 19 drives the pull rod 7 to move upward, so that the pull rod 7 drives the wedge block 6 to move upward, and then the wedge block 6 slides away from the inside of the connecting block 3. Then the worker pulls the connecting block 3 out of the connecting box 2, so that the worker switches to the wiring tube 4 that is suitable for the diameter of the electrical concealed piping. Then the worker inserts the replaced connecting block 3 into the inside of the connecting box 2. During the insertion of the connecting block 3, the connecting block 3 pushes the wedge block 6 to compress the fixing spring 5. When the wedge block 6 is fully inserted, the wedge block 6 is clamped in the inside of the connecting block 3 under the action of the elastic force of the fixing spring 5, thereby completing the replacement process of the connecting block 3. After the installation of the electrical concealed piping is completed, the worker pours a cast-in-place cement layer 9 on the device so that it completely covers the wiring box 1, thereby completing the installation process of the electrical concealed piping.
