(1) Design Description
1. The general description is consistent with the overall design, and whether the general description and the sub-description are conflicting.
2. Whether the pipeline in the human defense zone is a galvanized pipe, whether there is an alarm bell and an alarm button across the human defense door.
3. The design specification of the installation height and position of the equipment is consistent with the plan, large sample and so on.
(2) Floor plan
1. Sockets, lamps, switches, telephones, televisions, walkie-talkies, doorbells, and collection lines are fault-free, whether the installation location is reasonable, and whether it conforms to the architectural layout.
2. Are there large pipes such as SC70 and SC50 laid in the floor, causing the pipes to pass through and the thickness of the protective layer to be insufficient, and whether there is a concentrated arrangement of the rows of dark pipes (such as entering the shaft or concentrated in the corridor), resulting in the need to thicken the floor Or modify the installation method.
3. Whether the dark assembly electric box thickness and wall thickness match.
4. Whether the height of the anti-static board such as the telephone room and the information room affects the height of the switch and socket.
5. Whether the installation position, mode and height of lamps, switches and sockets are reasonable; whether the safety distance from other facilities meets the requirements of the specification.
6. Whether the design position of the distribution box is reasonable and whether it is convenient for construction.
7. The lighting distribution box is in the same position in the power plan and the lighting plan.
8. Whether the designed line, cable and pipe diameter meet the requirements of the specification and atlas when there is a bend.
9. Points such as shafts, machine rooms, power distribution rooms, etc.
10. Design whether the reserved holes meet the construction requirements, large-size bridges, pipelines consider the radius of gyration, construction space at the branch, plug-in bus lines and other large-scale lines, steering, continuity, etc., distribution boxes, cabinets, etc. Whether it is easy to construct and maintain.
11. Whether the position and size of the window, door and rear wall in the electrical drawing and the civil engineering drawing are consistent, and whether the size and structure of the wall of the distribution box meet the installation requirements.
12. Plug in busbars, bare busbars, etc. Large lines with poor water resistance consider the safety distance from professional water pipes.
(3) System diagram
1. Verify that all outlet circuits are protected against leakage, and that there are no settings in the drawings, especially the modified socket circuit.
2. Verify that the power and position of the electrical equipment (such as fans and pumps) in the electrical diagram are consistent with the HVAC professional, whether the control loop parameters match, and whether the conductor specifications meet the requirements.
3. Whether the contact with weak electricity, fire fighting, etc. meets the requirements, including the voltage level requirements, position of each electric valve, the setting of each electric contact pressure gauge, the distribution box that needs to participate in the fire linkage, and the weak electrical interface in the cabinet.
4. In the strong electric power distribution system, it is necessary to set the fire-strength control connection point, which is one-to-one correspondence with the fire protection system.
5. Check the plan, check the position of the box, the cabinet, the control circuit, the equipment used and its control equipment, whether it is reasonable, whether it is a phase-out product. Whether the system diagram and the plan plan are consistent (pipe diameter, laying method, Cable specification model).
6. Whether the designed wire, cable and pipe diameter meet the requirements of the specification and atlas when there is a bend, and whether the cable cannot pass through in the bending part.
7. Whether the control principle in the control system diagram satisfies the usage function.
8. Whether the power supply required by weak current is designed in strong electricity; (building control box, TV amplifier box, integrated wiring transfer cabinet, etc.).
9. Whether the distribution box arrangement in the shaft and small distribution room can be arranged, and whether the opening direction of the door intersects with the distribution box and cabinet.
