Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for constructing columns and beams, and more particularly to a method and a device for constructing a roof and a shelter for work under all weather conditions.

[0002]

2. Description of the Related Art Conventionally, in the case of constructing a building, first, a foundation is formed, and then pillars made of steel or the like are built, and between these pillars,
Beams are formed by horizontally passing and fixing steel materials for beams. In these works, it is usual to hang up a steel frame using a large crane, transport it to a predetermined floor, weld and bolt it to a predetermined place, and assemble the whole.

In this case, the work progresses from the lower floor to the upper floor, and after the pillars and beams of the first floor are assembled, the work is sequentially transferred to the upper floor by assembling the second floor. Go on.

[0004]

However, in such a conventional method, the assembly work proceeds in a place without a roof, so to speak, and the work depends on the weather.
If the weather is bad, the construction period will be delayed and it will be difficult to adjust.

Further, special equipment for installing the crane is required, and when the installation space is not present in the surroundings, the crane is attached to a part of the building, which requires a lot of labor for the work. Under these circumstances, the present inventor, as a result of various studies, built a roof in advance and climbed it while sequentially supporting it on the mast column toward the upper floor,
At the same time, the above problem was solved by using it as a support for the crane.

It is an object of the present invention to provide an all-weather method and apparatus for constructing columns and beams which can be used as a support for a crane and can be used for constructing columns and beams under a floor that serves as a roof. To do.

[0007]

The present invention has the following configuration in order to achieve the above object. That is,
First, the process of assembling a climbing floor that corresponds to the rooftop of a building on the ground, and while supporting the climbing floor with an arbitrary number of mast columns, raise the climbing floor to a height that can secure a space where work on the lower floor can be performed. It includes a step and a step of assembling columns and beams under the climbing floor, and these steps are repeatedly performed.

When dismantling the mast column without using it as a main column, the mast column is erected after the climbing floor is raised to a height where a working space on the lower floor can be secured. Pillars and beams to be provided in places other than the places are first assembled, and the mast column is sequentially pulled up, and the climbing floor is supported only by the assembled columns. Then, the process of assembling the remaining beam portions is performed.

Further, when assembling the pillar and the beam, the outer wall of the lower floor can be attached. If the above-mentioned work is performed by computer control, it can be performed accurately and quickly.
The apparatus for carrying out the above-mentioned method includes a plurality of mast columns that support the climbing floor, and a lifting mechanism that is attached to the mast columns and that lifts the climbing floor along the mast columns, and the lifting mechanism is used to lift the climbing floor. The top floor of the building is supported on the climbing floor, and the rails for mounting the overhead traveling crane are provided on the bottom surface of the climbing floor.

Further, in the lifting device, a plurality of mast columns which are erected upright are inserted into the climbing floor so that the climbing floor can be moved along the mast columns and can be detachably locked to the mast columns. An elevating body that is detachably engaged with the mast column is provided, and the elevating body and the climbing floor are connected by a stretchable jack.

Further, in the lifting mechanism, a plurality of mast columns provided with holes through which fixing pins are inserted at the same distance as one stroke of the jack are fitted into the climbing floor, and the climbing floor is covered with the mast column. Along with a movable body, and a mast column that can be detachably locked by a pin through which the hole is inserted, while the mast column is provided with a lifting body that is detachably locked by a fixing pin, The elevating body and the upper end of the climbing floor may be connected by a stretchable jack.

[0012]

Since the present invention has the above-described structure, the climbing floor corresponding to the roof of the building raises the mast column, and at the lower part thereof, a space for working on the lower floor is secured. Therefore, it is possible to work in any weather. Further, an overhead traveling crane can be attached to the lower surface of the climbing floor that is attached to the mast column and that is raised by a lifting mechanism that raises the climbing floor along the mast column, and the work of assembling the lower columns and beams can be performed.

The lifting mechanism fixes the lifting body to the mast column and then operates the jack to lift the climbing floor. Next, the climbing floor is fixed to the mast column at the raised position, the jack is returned to the original position, and the lifting body is fixed to the mast column again. By repeating this work, the climbing floor rises along the mast column for each stroke of the jack.

When the climbing floor reaches the top floor, it is used as it is as the rooftop of the building. In this way, the climbing floor, which is the roof portion, is gradually raised by the jack, so that reliable support can be obtained without adopting a complicated mechanism and safety can be secured.
