Door installation

1 scope

This technology is applicable to rated load 5000kg and below rated speed 3M/s and the following types of Chinese-made traction-drive elevator door installations.

2 construction preparation

2.1 devices, materials requirements:

2.1.1 door parts should be in conformity with drawings, quantity range.

2.1.2 sill, doors, Office doors should be no deformation of the slide, damaged. All other parts should be intact, functional and reliable.

2.1.3 production of steel bracket and bracket bracket steel to meet the requirements.

2.1.4 welded and bolted to the factory certificate.

2.1.5 cement, sand must conform to the provisions of chapter II.

2.2 the main tools:

Bench drill, hammer, level, steel ruler, square, welding tools, welding tools, wire pendant, oblique feeler gauges, small shovels, shovels, hammers, chisels.

2.3 operating conditions:

2.3.1 scaffold beams should be without prejudice to the stable loading sill, door installation and construction requirements.

2.3.2 the entrance hall and the scaffold on a clean, clutter-free. Protective door is safe and reliable. Fire safety measures, and designated personnel to watch the fire.

3 operational processes

3.1 process:

Steady load sill → install the door pillar, slides, door pockets machine → → installed Office doors, adjust the door locks, electric lock installation

3.2 steady loading sill:

3.2.1 by requirements by model put two root office door installation baseline (senior ladder best put three article line, that door in the a article line, door on both sides two article line), in Office door to Kan Shang draw NET door width line and the Office door center line, in corresponding of location playing Shang three a lying points, to baseline and the this logo determine to kan, and cattle leg and the cattle leg bracket of installation location (Figure 5-53).

3.2.2 If the sill bracket to concrete structures, rinse with water, will put his paw on the sill. Then use the fine stone concrete (cement grade not less than 325#. The volume ratio of cement, sand and stone is 1:2:2). Sill with stabilization level leveling feet, while three-bedroom respectively are three baselines, and finding a good distance from the line.

Cooking good stability should be higher than the finished decorating the ground 2~3mm, if finished decorating the ground for concrete to, then 5~10MM should be high, and according to 1:50 grade concrete floors and sill flat trowel (Figure 5-54).

3.2.3 If no concrete door bracket, embedded iron welding on brackets, installation of steel bracket to steady loading sill, in two ways:

3.2.3.1 lift rated load in the elevator up to the 1000kg, available not less than 65mm angle steel frame, welded, and steady load sill (Figure 5-55). Corbel brackets of not less than 3.

3.2.3.2 lift more than rated load 1000kg of all types of elevators (not including 1000kg) δ =10 plate and trough can be used steel Corbel bracket, welded, stable loading sill outside (Figure 5-56). Corbel brackets of not less than 5.

M1 and M2 are respectively marked (l for car guide spacing).

3.2.5.2 stability when loading sill, square measurements, the hall door sill from the car side before the two rails are in the size of B+H-d/2

B--

H——

D--car guide car sill centerline to edge size;

Elevator sill and door sill from the Office (usually 25mm or 30mm);

Car guide working face width.

3.2.5.3 about moving the door sill to M1, M2 and align the square outside corners, so that the location of the sill is determined (Figure 5-58). To review the Office center point is correct, m door sill center point can be measured from the cabin two lateral edges of the rail distance, S1 and S2 are equal (Figure 5-59).

3.3 Installing the slides, on the door pillars, door

3.3.1 sill installation door pillar after hardening. Brick wall with the discerning wall eyes buried anchor bolt (Figure 5-60).

3.3.2 if any embedded iron concrete structure wall, screws can be welded directly on the embedded iron (Figure 5-61).

3.3.3 wall concrete structure without embedded iron, add location to the corresponding M12 expansion bolts 2 150mmx100mmx10mm steel used as embedded iron installed (Figure 5-62). Other installation above.

3.3.4 If the door slides, door pillar to circle away from the wall than 30mm should be fixed if the washer higher use made of thick steel pipes welded on both ends processed iron, to ensure that they are firmly (Figure 5-63).

3.4 Installing the door, adjusting the door:

3.4.1 feet at the end of the door, door pulley mounted on the door, turn the cam to the maximum value (and sliding distance). And guide at the end of the foot into the door sill trough, hang round on the slide.

3.4.2 in 6mm thick on the doors and sill pad support. Pulleys with special gasket between the frame and door leaf adjustment, so as to meet the requirements, then the wheel frame and the door leaf fastening the connecting screws, the repatriation of the eccentric wheel to slide the spacing is less than 0.5 m m, removed doors and sill pad things, coasting test, reached the light easily qualified (Figure 5-65).

3.5 lock, electronic lock, safe switch installation:

3.5.1 installed prior to locking, locking arms, rollers, springs and other adjustments as required, making it flexible and reliable.

3.5.2 locks and door safety switch according to the drawing provided locations for installation. If the mounting screw holes on the device meets the requirements of drawing you want to modify.

3.5.3 adjust door locks and door safety switch, to reach only two doors (or fans) off met the requirement in order to make door lock electrical contacts and the door safety switch.

If the door fixing screw holes for adjustable, locks in place installation and adjustment, you must add set screws to prevent locking shift.

3.5.4 when the car door and hoistway door linkage, hook lock should be no decoupling and the tool holder, the door should run smooth, jitter-free and crash.

4 quality criteria

4.1 the elevator sill and hoistway door sill pitch deviation of each layer no more than mm.

Inspection method: standard checks.

4.2 open knife with the hoistway door sill and door opening set of wheels car gap between sill and must be within the scope of 5~8mm.

Inspection method: standard checks.

4.3 the Office doors slide on lateral vertical plane inside of the sill slot vertical distance a, should conform to the drawings, slides on the ends and the Middle three (1, 2, 3) wait for measuring relative error shall not exceed ± 1mm. Track and sill on the parallelism error should be less than 1mm. Guide is not Plumb a ' shall be not more than 0.5mm (5-66).

Inspection method: hanging, standard inspection.

4.4 Hall doors vertical deviation is less than 2mm, out the door opens is not greater 10MM, turn eccentric wheel door slide clearance shall not exceed 0.5mm.

Inspection method: hanging, standard inspection.

4.5 door installation, adjustment should be to:

Doors smooth, clean and without damage. Brisk opening and closing smoothly. Also closed when the door is closed in, the door.

4.6 office door frame pillar dip errors and on slide level errors should not exceed 1/1000.

Inspection method: do open and close Visual check.

4.7 after the door closed, machine locks should be immediately locked the door, and for its flexible, hook has 1mm activity (Figure 5-67), hook is locked in the Office door, not the door opens.

Inspection method: standard and Visual check.

4.8 after the door closed, door lock electrical conductivity and contact must be good. If the door mounting holes for adjustable door town after installation and adjustment, you must add set screw fixed.

Inspection method: Visual check. 4.9 office door door bottom and sill gaps at 6 ± 2mm.

Door with door spacing of 6 ± 2mm.

Inspection method: standard checks.

4.10 allows deviation:

Hoistway door sill and door installation size, tolerance and inspection methods should meet the requirements of table 5-10.

5 finished product protection

5.1 the doors, door sets, sill has a protective film to completion before you can remove the protective film.

5.2 door components in the construction process to protect, not to break it.

5.3 filling gaps between the wall and calls for measures to prevent deformation of the door.

6 quality problems to be noticed

6.1 fixed when steel door frame, welding on stiffening the door, do not weld directly on the door.

6.2 all welded and bolted the fixed part must be solid and reliable.

6.3 usually need embedded in concrete components, must be checked by the relevant departments to handle the concealed work procedures, to pouring concrete.

6.4 If there is damage, deformation of the various components of the Office and must be repaired or replaced, qualified before the use.
