Common sense about how to do hydropower installation in steel structure villas? 1. First installation and positioning Before construction, you should be familiar with the circuit drawings, and mark them with a marker on the wall according to the position and height marked by the sockets and switches on the drawings. 2. Reinforcement production First measure the width of the position where the bottom box needs to be installed, then draw a 4 cm connection at both ends of the C-shaped steel, extend it to the side, cut off the excess part, and fix the cut C-shaped steel on the wall. , install the U-shaped steel on the C-shaped steel to complete the reinforcement. 3.

If more than two bottom boxes are installed, the bottom box connections must be fastened. 4. Drilling line holes After the bottom box is installed, the construction personnel install the hand drill on the D25 hole opener, and open the corresponding line pipe holes at the top beam directly above the bottom box. Open 2 holes in the floor beam position above the socket, and open 3 holes in the switch. 5. After the pipe through hole is opened, carry out the construction of the wiring pipe. The pipe layout should be carried out in an orderly manner, and the construction should be carried out in accordance with the loop sequence, so as to be horizontal and vertical. Reinforce both ends. 6. Pipe bends When using a cold bender pipe bender, place the section that needs to be bent above the knee and press down slowly to make the bending angle larger for threading. 7. Threading After the wire pipe is completed, start the threading work. The threading starts from the power distribution box, and is passed from the front to the back. No leakage occurs.
