That is, in the elevator construction method of the present invention,

An upper mold plate installing process for installing the upper mold plate 16 on the upper portion of the hoistway 10 and a lower mold plate installing process for lowering the steel wire from the upper portion of the elevator shaft 10 to connect the lower mold plate 17.

And raising the elevator rails to connect the elevator rails 11 through the upper and lower mold clamping steps S110 to raise the elevator rails 10.

A car installation process (S110) in which the car 12 is installed on the hoistway 10 after the elevator rails 11 are connected.

In addition, it is possible to further include a falling shock absorbing installation step of installing a fall air matt 13 for preventing damage when the car 12 falls during the car installation step S130.

And a car moving rail fixing process (S140) in which the fluorescent identification welding and the anti-corrosive coating are performed when the elevator rail (11) is fixed to the wall surface after the car installation process (S130).

And a template removing process S150 for removing the upper template 16 and the lower template 17 after fixing the elevator rail 11 through the car moving rail fixing process S140.

When the template is removed through the template removal process (S150), a car finishing process (S160) for finishing interior and exterior construction of the car (12) is included.

And the high speed start-up procedure (S170) is performed by the car 12 in a high speed up and down operation along the elevator rail 11. [

Also, a rail inspection process may be further included for inspecting the rail through the vibration and heat sensation in the rail condition during the high-speed start-up operation (S170).

And a maintenance process (S180) for finely repairing the rail after the rail inspection process (S130).

Here, in the elevator rail connection raising step (S120), the elevator rails 11 are installed through the rail jig binding process. That is, when raising the elevator rail 11 in the elevation direction of the elevator shaft 10, rail connecting ports 11a are provided so that both sides of the elevator rails 11 are fixed so that they do not deviate from each other.

The crash damper installation process of installing the falling air mats 13 under the car in the car installation process S130 is performed by mounting the car 12 on the elevator rail 11 constructed through the connection raising process of the elevator rails 11 A falling air mat 13 is installed on the lower part of the hoistway to prevent the operator from being injured and to prevent damage to the car 12 when the hoistway motor 10 is mounted on the hoistway 10.

The fall air mats 13 are provided with a fall sensor 13a which senses falling speed and a direct collision with the rail and friction and operates it to instantaneously become bulky by the internal gas filler to reduce the fall height, .

For example, the crash sensor 13a is installed on the car 12 and is connected to the crash air mat 13 by a cable. At this time, the cable is fixed to the fall sensor 13a and is formed between the elevator rails 11, and a winding device for continuously winding the cable 13b inside the fall air mat 13 is formed.

When the cable 13b exposed between the fall sensor and the rail 11 is broken at the high frictional heat generated in the elevator rail 11 at the time of the fall, the winding device winds the cable 13b, The gas filler valve is opened and operated

In addition, the falling air mat 13 can be instantaneously discharged by the pressure caused by the fall, so that the discharge port can be formed so that the car 12 does not bounce up.

In addition, it may further include that the reversing device is installed on the car 12 that detects the fall when the vehicle falls.

The reversing device senses the impact of the car 12 when it collides with the elevator rail and the heat due to the friction, and injects gas from the inside of the car 12 to generate reverse thrust. Therefore, when the car 12 is falling, the amount of impact of the fall can be reduced through the reverse thrust of the reversing device.
