Abstract

PURPOSE: To install large main rope reels and feeding cable reels by forming a temporary machine room with a first layer where a winding machine and a control panel are installed and a second layer where the main rope reels and the feeding cable reels are installed. CONSTITUTION: For construction work while jumping up a temporary machine room 2 on the way of an upper floor in the process of the construction of a high-rise building, the temporary machine room 2 is formed with a first layer 6 and a second layer 7 disposed thereon. The first layer 6 is formed into a box of shape steel, on the floor surface 6a of which a finger beam 29 is mounted in an accessible manner to be engaged with a steel frame 30. The floor surface 6a is provided with a winding machine 3 for elevating up and down a working box and a control panel 8. On the other hand, the second layer 7 includes a plurality of supporting shafts 13-15 laterally mounted on which a plurality of main rope reels 16, 19 and feeding cable reels are supported in a rotatable manner.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary machine room for a jump-up elevator, which is adapted to be moved according to the progress of construction of a construction frame.

[0002]

2. Description of the Related Art Conventionally, a movable temporary machine room, which is composed of a table to which a drive device such as a hoisting machine and a control device are attached, quickly moves (jumps) from one floor to another as construction work progresses. A jump-up elevator is used.

That is, a temporary machine room, which is a combination of temporary parts and a part of the main equipment, is temporarily installed in the hoistway of the main elevator, and the elevator is operated from the lower level according to the progress of the construction of the construction frame. . Next, as the construction of the steel frame progresses, the temporary machine room is lifted by a crane every few floors and temporarily installed in the hoistway, and the elevator is operated again.

[0004]

In such a conventional jump-up elevator, when it is installed in a high-rise building, the main rope for pulling the car and the power feeding cable for feeding the car , It has to be lengthened according to the height of the hoistway, and inevitably the reel for the main rope and the reel for the power supply cable around which it is wound become large. Here, the reel for the main rope and the reel for the power feeding cable are installed in the temporary machine room. Therefore, there is a problem that the large-sized main rope reel and the power supply cable reel cannot be installed in the temporary machine room due to space limitations.

An object of the present invention is to provide a temporary machine room for a jump-up elevator in which a large-sized main rope reel and a power supply cable reel can be installed.

[0006]

In order to achieve such an object, according to the present invention, a hoisting machine for driving a car and a control panel for controlling the driving of the hoisting machine are provided. The installed first layer part, the main rope reel around which the main rope for pulling the car is wound, and the power cable reel around which the power cable for supplying power to the car is wound around. And a layer portion.

[0007]

Since the reel for the main rope and the reel for the power feeding cable are provided in the second layer portion different from the first layer portion provided with the hoisting machine and the control board, the reel for the main rope and the power feeding cable are provided. Even if the cable reel is large, it can be sufficiently provided in the second layer portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 7 are views showing an embodiment of a temporary machine room of a jump-up elevator according to the present invention.

In FIG. 6, reference numeral 1 is a high-rise building under construction (for example, the total height is 30 floors), and an intermediate floor (for example, 1 floor).
It is a hoistway when it is completed up to the 0th floor). The temporary machine room 2 is on the top floor (10th floor) of this hoistway 1.
Is temporarily installed, and the hoisting machine 3 provided in the temporary machine room 2 vertically moves the construction car 4. As a result, the worker of the building under construction plays a role of vertical transportation, and the worker uses this transportation to work.

Next, during the above-mentioned work, in a high-rise building under construction, the hoistway is on an intermediate floor (for example, 20
If it is completed up to the first floor, the temporary machine room 2 is lifted by a crane to temporarily install it on the intermediate floor above the floor as shown in FIG. 7, and the above work is performed again.

Here, as shown in FIG. 1, the temporary machine room 2 is composed of a first layer portion 6 and a second layer portion 7 located thereon. The first layer portion 6 is formed of a shaped steel into a box shape, and as shown in FIG. 2, a finger beam 29 that can be moved in and out is attached to the floor surface 6a of the first layer portion 6. Are engaged on the steel frame 30. Further, a hoisting machine 3 for vertically moving the construction car 4 and a control panel 8 for controlling the drive of the hoisting machine 3 are provided on the floor surface 6a. The hoisting machine 3 has a drive sheave 9, and a main rope 10 for pulling the construction car 4 is hung on the drive sheave 9. Further, a shaped steel 11 is laid horizontally in the first layer portion 6, and a clipping sheave 12 is rotatably supported on the shaped steel 11.

The second layer portion 7 is also made of shaped steel into a box shape. As shown in FIG. 3 and FIG. 4, a plurality of support shafts 13, 14, 15 are laterally installed in the second layer portion 7, and the support shafts 13, 14 are connected to the main rope reel 16, 17, 18, 19, and 20 are rotatably supported. Further, as shown in FIG. 5, the power feeding cable reels 21 and 22 are rotatably supported on the support shaft 14, and the power feeding cable 23 wound around the power feeding cable reels 21 and 22 (see FIG. 1) is connected to a car operation panel or the like in the car 4 for construction. The main rope reels 16, 17, 18, 19, 20 and the power supply cable reels 21, 22 are provided in a second layer portion 7 different from the first layer portion 6 provided with the hoisting machine 3 and the control panel 8. Because it is provided,
This main rope reel 16, 17, 18, 19, 2
0 and the feeding cable reels 21 and 22 can be sufficiently provided in the second layer portion 7 even if they are large in size.

Here, the reels 16, 17, 18, 19,
As shown in FIG. 6, the main rope 10 fed out from 20 is hung on the sheave 24 of the car 4 for construction after being wrapped around the gripping sheave 12, and further hung on the drive sheave 9 of the hoisting machine 3. Counterweight 2
It is hung on the sheave 26 of 5. One end side of the rope 10 is pressed by the rope clamp 27 so that the first layer portion 6
, And the other end is fixed to the fixing portion 28 of the first layer portion 6. In addition, construction basket 4 and counterweight 2
The hoisting machine 3 that moves the 5 up and down, by the principle of the moving pulley,
The power is half compared to the case where the rope is directly attached to the car and the counterweight.

[0014]

As described above, according to the present invention,
Since the reel for the main rope and the reel for the power feeding cable are provided in the second layer portion, even if these reels are for a high-rise building with a large size, they can be provided in the temporary machine room. Also, by installing a reel on the upper part of the hoisting machine, it is possible to easily feed the main rope, and it is also useful for protecting the upper part of the hoisting machine.
