JPH07145672A - Device for raising up column member - Google Patents

Abstract

PURPOSE:To raise up a column member safely at low cost by a method wherein the lower end of the column member is placed on a platform of one truck while the top is placed on the other truck, and the hanging center of the column member placed on the other truck is hoisted up with a wire ripe. CONSTITUTION:The lower end of a column member 1 is placed on a platform 2 of a truck A and the top of the column member 1 is placed on a truck B. As the balance for rotation is considered with the center of gravity for the platform 2 of the truck A penetrating through a horizontal shaft 3, optional rotative positions can be taken manually without the need for excessive force. A wire rope is wound round the hanging center of the column member 1 placed on the truck B, and wound up slowly with a crane. Then, the top of the column member 1 is elevated slowly while the lower end of the column member 1 rotates round the horizontal shaft 3 on the truck A, and the truck A moves on rails 7 toward a position beneath the hanging center. When hoisting-up is completed, the column member 1 is placed upright and set on a specified position.

Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention relates to a device for unloading horizontally and erection of a column member temporarily placed.

[0002]

2. Description of the Related Art In the case where a column member temporarily placed horizontally is to be erected, a method is generally adopted in which two cranes are used to suspend each other.

[0003]

However, there are the following problems in the method of constructing a pillar material by suspending two cranes which are generally used in common.

(A) Since the two cranes are suspended from each other, the operator's cues of the cranes are complicated, and the danger of dropping the suspended load is high.

(B) Therefore, the construction cost is high.

(C) For example, when the pillar member is a precast box pillar, there is a risk that the surface may be damaged by a wire or the like, or a steel frame pillar in which a joint member is welded may be damaged by colliding the welded portion with the floor. There is a nature.

The present invention has been devised to solve these problems.

[0008]

A pillar member erection device according to the present invention is a bogie A having a function of rotating an end of a pillar member and a bogie for horizontally supporting the other end when the pillar member is mounted on the carriage A. B and a rail mount on which the carriage A and the carriage B travel.

On the carriage A, there is pivotally mounted a mounting table on which a terminal of a pillar member is mounted and an end of the pillar member can be rotated around a horizontal axis.

The carriage B has a flat top portion for supporting the other end of the pillar member, and is adapted to travel on a rail mount slightly longer than the pillar member together with the carriage A. The lower part of the pillar member is placed on the platform of the carriage A, and the upper part of the pillar member is placed on the carriage B. When erected, the hanging core of the pillar member at the portion of the carriage B is slid with a wire rope. When gradually lifted by a crane, the upper part of the pillar member floats up from the carriage B and the lower part of the pillar member remains on the platform of the carriage A while rotating around the horizontal rotation axis so that the pillar is gradually raised and at the same time the carriage A moves below the suspension core. The column member becomes vertical when it is directly below the hanging hook of the crane, and is set at a predetermined position.

EXAMPLE FIG. 1 is a view showing a state in which a precast box column 1 is about to be erected. FIG. 2 is a side view thereof.

The precast box pillars 1 received from the factory are horizontally unloaded and temporarily placed. The lower end is mounted on the L-shaped board 2 of the trolley A in a horizontal state during erection. The platform 2 is pivotally attached to a shaft 3 provided at the center of the upper portion of the carriage A, and is freely rotatable around the shaft 3.
Moreover, when the pillar member 1 is not mounted on the boarding platform 2,
The rotation balance is taken into consideration so that the shaft 3 penetrates the center of gravity of the platform 2 so as to be stationary at any rotation position.
Further, the portion where the pillar member 1 abuts is a rubber plate 4 as a cushioning material.
When the main bar 5 of the column member 1 is extended as shown in the figure, a hole through which the main bar 5 penetrates is provided at the end of the L-shaped board 2 or the main bar 5 is formed to escape the main bar.

Wheels 6 are attached to the lower part of the carriage A and rails 7 are attached.
It is possible to move freely on the above.

The carriage B supporting the top of the pillar member 1 is a carriage B.
A cushioning rubber 4 is adhered to the upper part to prevent the pillar member 1 from being damaged and has a flat structure. Rail 7 at the bottom as well as truck A
Wheels 8 are provided so that they can move freely above. When the pillar member 1 becomes large and the suspension core on the trolley B is far from the ground, a step 9 is provided so that the suspension core can be easily reached. Reference numeral 10 is a handrail of the step stool 9. Numeral 11 is a stopper for preventing the carriages A and B from derailing from the rails.

Next, the operation of this apparatus will be described. Before erecting the pillar, the lower end of the pillar member 1 is mounted on the board 2 of the carriage A as shown in FIG. In this case, as described above, the L-shaped board 2 has a rotational balance with respect to the rotary shaft 3, so that it is possible to manually and smoothly take a free rotational posture without requiring excessive force. There is no danger above. At the same time, the top of the pillar member 1 is mounted on the carriage B. Then, the wire rope is slung on the suspension core of the pillar member 1 on the upper portion of the carriage B. In this case, when the pillar member 1 is large and the height to the suspension core is high, the step 9 is used. When the sling is finished, gradually hoist it with a crane. The top of the pillar member 1 gradually floats above the carriage B, and the lower portion of the pillar member 1 rotates around the rotation shaft 3 of the carriage A while the carriage A moves toward the lower portion of the suspension core. When the column member 1 is completely lifted, the column member 1 is set vertically and set at a predetermined position.

Although FIG. 1 illustrates the example of the precast box column, the present apparatus can be applied to other steel frame columns.

[0017]

The effects of the present invention are as follows.

(B) The crane operates only by hoisting,
The work is very safe because it is extremely simple.

(B) Since the number of slinging personnel and phase number cranes can be reduced, the construction cost can be reduced.

(C) The construction quality can be secured without damage to the surface of the precast box column or damage to the joint of the steel frame column.
