Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push-up device for assembling a building body on the ground and sequentially pushing up the whole body to construct a building body.

[0002]

2. Description of the Related Art The present applicant has already made a plurality of proposals regarding such a push-up device for a building skeleton. (For example, Japanese Patent Application No. 5-259756).

[0003]

However, in the case of the conventional push-up device, when the building frame is pushed up, the push-up device is constructed so as to rise in a lengthy scale. The push-up device is not in the same state, and it may not be possible to stop in a stable state.

Therefore, it is an object of the present invention to provide a continuously rising push-up device which can be stopped in a stable state even in an unpredictable situation such as a power failure or a failure.

[0005]

According to the present invention, in a push-up device for assembling a building frame on the ground and sequentially pushing up the entire structure to construct a frame, a pair of gate-type mounts are provided,
The screw rods are non-rotatably suspended on each of the gate-shaped mounts, and nuts are screwed onto the screw rods.The nuts are rotatably attached to the pressure bearing plate supporting the body part, and the pressure bearing plates fall. A drive means is provided for engaging the stop and driving the nut. The driving means is provided with a worm wheel on the outer circumference of the nut, and has a reduction gear and a motor which are constituted by a worm that meshes with the worm wheel.

Further, the speed reducer may be composed of a worm wheel and a worm for a plurality of stages of speed reduction, and a plurality of screw rods may be provided on each of the pair of gate-shaped mounts.

[0007]

Since the present invention is constructed as described above, when the motor rotates the nut screwed to the screw rod via the speed reducer, the bearing plate engaged with the nut is pushed up. , It is possible to push up the frame placed on the bearing plate. When pushing up the entire building body, a plurality of push-up devices may be arranged so that the weight of the body is distributed as much as possible. In addition, since it is a continuous rise by the rotating means, not only a smooth rise is possible, but also a strict rise amount control is possible by control using an encoder. It can be stopped stably by the worm structure, and can be descended by reversing the motor.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, two gate-shaped mounts 1 and 1 are built on a base G at predetermined intervals and vertically held by a stay 10a. Also, referring to FIG. 2, the portal frame 1 is provided with a pair of pillars 1a and 1a on a base G, and is connected by a connecting member 1b provided on the upper part of the pillar 1a. A threaded rod 2 is suspended in the. Further, the screw rod 2 is non-rotatably fastened to the connecting member 1b by the fastening means 3, a nut 5 is screwed to the screw rod 2, and the nut 5 has a worm wheel (not shown) formed on the outer periphery thereof. It has a one-stage or two-stage speed reducer 8 composed of meshing worms, and a pressure bearing plate 4 having two holes 4a through which the screw rod 2 is inserted is provided on the speed reducer 8. .

The speed reducer 8 is connected to the motor 7 via the gear box 6, and the outer circumference of the screw rod 2 is bellows 9.
It is covered with a telescope.

FIG. 3 is a sectional view taken along line AA of FIG.
Stays 10c, 10d and 11 orthogonal to 0a and 10b
With reference to FIG. 4 as well, the stays 10a and 10b are used as standard in all cases, and other stays 10c and 10d are referred to as c and 11d.
The patterns d, 11c, and 11d may be selectively used according to the use place like the pattern P1, the pattern P2, and the pattern P3.

The operation mode of the push-up device will be described below in the case of the above-mentioned frame B. When pushing up the skeleton B, referring to FIG. 4, the pattern 1 is set at four locations so that the beams at the required locations on the skeleton B are placed on the bearing plate 4.
If pattern 2 is selected at 2 locations and pattern 3 is selected at 4 locations and the push-up device is set, the motor 7 is rotated and the nut 5 is rotated through the gear box 6 and the speed reducer 8. The bearing plate 4 in engagement continuously rises while the motor is rotating.

Ascending to a predetermined height as indicated by A,
A support 12 is put under the beam to temporarily support it, and the bearing plate 4 is lowered.

In this case, since the pressure plates driven by one motor and moved up and down by two nuts are mechanically connected, they can be raised and lowered horizontally in accordance with the rotation of the motors to control the rotations of a plurality of motors. By doing so, the level can be arbitrarily maintained.

Therefore, the push-up can always be performed in a stable state, and even if the power is stopped due to a power failure or the like, it can be stopped stably, which is safe.

[0016]

Since the present invention is constructed as described above, it has the following excellent effects.

(1) Since the elevator can be continuously moved up and down, even if the device stops due to a power failure, an earthquake, etc. during the ascent and descent, the building frame can be stably supported in that state.

(2) It is stable because the gears can be branched so as to have the same rotation speed and can be mechanically tuned.

(3) Even when the push-up amount is made different from that of another push-up device, an arbitrary level difference can be made because of the continuous system.

(4) Therefore, the push-up method can be carried out stably and safely.
