How to measure the elevator shaft and what is the elevator shaft?

One. Hoistway plane dimensions.

1) Shaft width: Facing the elevator hall door, measure the clearance size of the two walls of the shaft.

2) Shaft depth: the size of the clearance between the inner wall of the hall entrance and the back wall of the shaft (if the shaft is too deep, you can find a thinner long rod to go deep into the shaft, and then measure the long rod, and pay attention to whether there is a verticality deviation in the shaft and whether there are beams and columns in the shaft).

Two. 1) The width and depth of the door opening and the position size of the call hole, as well as the width of the wall buttresses on the left and right sides, determine whether the center of the door is the center of the feeding well.

2) Whether there is a door head beam above the door opening, and whether there is a corbel below the door opening. Floor height (the vertical distance between the ground and the ground of two adjacent floors) can be measured with a ruler or a thin stick instead of a thin stick.

Four. The height of the top floor, the net size between the ground and the lower skin of the hoistway roof after the completion of the top floor decoration.

Fifth, the depth of the pit, the depth from the lowest layer of ground to the pit.

Sixth, the wall structure, whether the brick wall has ring beams, the center spacing of the ring beams or concrete Seven, the length and width of the machine room, as well as the height between the lower edge of the hook and the upper skin of the roof of the hoistway, the position and size of the machine room opening.

And so on...

Length, width and height, plus slope. If the drawing is a 2000x2000 top view, the upper side is also the lower side, but the difference between the upper and lower sides of the hoistway is 200, then the elevator is installed and becomes a 2000x1800 hoistway.

There are drawings to look at directly, although there is a bit of a discrepancy, but it is quite authoritative.

If you don't have it, take a box ruler, measure the depth of the pit in the pit, measure the height of the top layer on the top of the car, and the height of each layer is about one or two layers, and the total height will naturally come out. Measure the length and width of the shaft in the pit. It's basically OK

Pit Depth! The width of the hall door on each floor (the distance from the hall door to the left and right hoistway walls), the height of the hall door!

Top Floor Height! Very important!

Raise the height! The length and width of the hoistway!

It is recommended to use a laser rangefinder with high accuracy!

The method of measuring the elevator shaft is as follows:

1) Shaft width: Facing the elevator hall door, measure the clearance size of the two walls of the shaft.

2. The depth of the hoistway: the clearance size between the inner wall of the hall entrance and the back wall of the hoistway;

3. The width and depth of the door hole and the position size of the old call ladder hole of the bridge, as well as the width of the wall buttresses on the left and right sides, judge whether the center of the door is the center of the fish feeding well;

4. The height of the liquid ascending layer can be measured by a ruler or a thin stick instead of measurement.

The building does not require the oak to be used as a place to prevent the spread of flames, and the shaft does not need to be fully enclosed, but a fence needs to be set up where the elevator can be approached by personnel: the height of the door side is not less than; On the remaining side, when the horizontal distance between the fence wall and the moving parts of the elevator is the minimum allowable value, the height should not be less than; If the horizontal distance is larger, the height can decrease with the distance; When the distance is equal to, the height can be reduced to a minimum; The maximum distance between the wall and the edge of the Xuntuan floor, staircase or platform is three) the access door, the safety door leading to the hoistway, the hoistway safety door and the maintenance trap door, except for the safety or maintenance needs of the user, generally should not be used, the height of the access door shall not be less than, the width shall not be less than; The height of the hoistway safety door shall not be less than and the width shall not be less than. When the distance between the adjacent two layers of door sill is greater than 11m, the hoistway safety door should be set up to ensure that the distance between adjacent sill is not more than 11m.

The access door and the hoistway safety door should not be opened into the hoistway; All should be installed with a key to open.

When two or more elevators are installed in a shaft, a middle beam is required in order to install a guide rail between the two cars. The middle beam is ordinary I-shaped steel 200x100 mm, or channel steel 200x90 mm, and is buried in the front wall and rear wall of the hoistway. Since the specified length of the guide rail is 5 meters, and a guide rail needs to be fixed in at least two places, the installation spacing of the upper and lower directions of the middle beam is 2 meters.

The smallest elevator shaft in China is 1250mm wide and 1450mm deep; The hoistway is mainly used in villa elevators. The smallest sightseeing elevator shaft is 1600mm*1600mm, the sightseeing elevator is in the form of fan-shaped sightseeing, used in shopping malls, villas, and may be a little small outside Xiangxiang.

The two elevator shafts can carry 320kg, which is also the smallest elevator shaft at home and abroad, and meets the national requirements of 320kg for manned elevators.
