From the elevator design, construction, owner acceptance should pay attention to design, construction, acceptance in the operation of the project if there are imperfections, if it is good to change the pre-construction drawings, if it is not found or rectified after the completion of acceptance of the project, it is necessary to leave the project with accident hidden dangers, Heigel household elevator is willing to work frequently occur. Several questions should be notified to the peers. If the conclusions are not in conformity with the norms, the norms shall prevail.
1. In the preliminary design of the project, the owner should first determine the elevator specifications, manufacturer, model, intelligent requirements, the main design of the elevator model to determine the size of the well, reserve control buttons, monitors and other reserved ports, to prevent the change of the elevator model, to bring repetitive construction.
2. Drainage wells should be reserved in the bottom design of elevator. The drainage volume should not be less than 2 m?, the drainage volume of drainage pump should not be less than 10 l/s, or the diameter of reserved drainage pipe should be 100-150 mm. When fire fighting, backflow water in elevator should flow smoothly to underground drainage wells.
3. Elevator track and equipotential connection. There are three methods: the first method is to use the main steel bar of the shear wall of the elevator shaft to be larger than 6mm, and reserve an equipotential connection point to weld the elevator track every 3-5 layers of the steel bar. The second method: in the bottom layer, the top layer draws two points from the lightning conductor, and reserves the equipotential welding with the track every 20 meters near the lightning conductor. The third method: in the bottom layer, the top layer draws two reserved equipotential points from the lightning arrester lead and directly sets 25*4mm hot dip galvanized flat iron to weld with rails. The grounding should be that the section of auxiliary equipotential steel bar is larger than 6 mm2, and the lightning protection lead should be more than 48 mm2, according to the design specifications.
4. The standard spacing of the elevator for well lighting is 7 m, and a socket circuit is added to the civil design code. The leakage switch can be added to the second circuit combined circuit switch. When the elevator is installed on the spot, the power supply on the sedan car is generally 220 V, which makes the lighting and socket construction convenient. The design position of well lighting should not be located in the rear of the car, because of the weight shielding, nor on the right side of the car. This space is the car control cable running channel, good position can be located on both sides of the car left track.
5. There should be alarm button, fire telephone and emergency light in the car. The blackout time should be 90-120 minutes.
When the building grade is 1 or 2, the double power box of the elevator should be located at the last stage of the load and in the fire elevator room. The main switch of elevator room should be separated from the power supply of elevator main engine, car lighting, engine room lighting, well lighting, maintenance socket and drainage machine.
7. Fire-fighting elevator room and passenger elevator room should be separated by firewall.
8. The floor structure of non-bottom elevator shaft should be strong enough to bear elevator impact force.
9. Super high-rise high-speed elevator should reserve elevator buffer space.
10. The front room of the elevator should be redecorated twice. The passenger elevator door should not be reserved more than 6 mm and the cargo elevator should not be more than 8 mm. "Code for Fire Protection in High-rise Civil Architectural Design": It is necessary to take waterproofing measures for control lines. For example, in the elevator door
A 40-50mm overflow slope. Inside the elevator door canal, the elevator door canal is 50 mm high and flat with the corridor. It is not affected to step out of the elevator. Practice has proved that flood slopes are reserved according to fire protection regulations, and running elevators do not enter water. Usually 6 mm is reserved according to elevator specifications. Once pressure test runs out of water, pipeline valves freeze and crack, fire fighting also encounters many times in construction. Once the running elevator is flooded, the elevator can not run, disputes continue, I hope to draw attention to this summary.
Family elevator manufacturers inherit craftsmanship and aesthetic and design concepts of Europe and America. The United Nations senior design team has created outstanding performance of Haiger family elevator in civil construction, decoration design, component design and other aspects, and created elevator space with aesthetic quality and humanized elevator ride experience.
Villa elevator manufacturers uphold the Swedish royal style of housekeeping service, on the basis of ensuring safety first. In terms of details and services, customers are always given lofty enjoyment, so that customers can enjoy royal treatment at home, truly reflecting the high value of service. Haiger has always made persistent pursuit and unremitting efforts.
