Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention can be preferably applied to the construction of various structures from low-rise to high-rise without requiring manpower (that is, as unattended as possible). The present invention relates to a personalized construction device.

《Prior art》 Generally, for the construction of various structures such as middle- and high-rise buildings, after constructing pillars up to the top floor, the slabs assembled on the ground are sequentially pulled up with a winch or mounted, or the body members are mounted with a crane or the like. It is carried out by methods such as lifting, building from the lower floor to the upper floor for each one floor, and stacking.

FIG. 5 is for explaining the latter method, and shows that the first and second floors have already been constructed and the third floor has been constructed. That is, the worker H rides on the floor of the third floor and is lifted by the crane C.
Then, it is attached to the predetermined position on the third floor by welding, bolts or other means.

In addition, recently, a plant installed on the first basement floor was used to intensively construct a building for the first floor using machines such as robots, and after the completion of the construction work for the first floor, push up by the height of the floor. There has been proposed a method of repeating the above process to construct the entire building (see Japanese Patent Laid-Open No. 62-244941).

<Problems to be solved by the invention> However, there are many methods for pulling up and installing the slab with the winch after building the pillars up to the top floor, and for building every floor from the lower floor to the upper floor. It takes manpower,
Due to weather conditions and restrictions on work time, etc., it often led to an extension of the construction period, and it was necessary to give great consideration to the safety of workers.

Further, in the above-mentioned method of the previous proposal, although such a problem is considerably solved, a member for supporting the structure under construction,
That is, there is a problem that the height of the building is limited due to the strength of the members pushed up.

Furthermore, as the construction progresses, the floor height of the building will become considerably higher and the weight will become heavier. Therefore, if the plant is built on the first floor above the ground, it will not be possible to support the building pushed up. Could be unstable, and there was a problem with earthquake resistance during construction.

The present invention solves the above problems, and can be preferably applied to the construction of various types of buildings from low-rise to high-rise as much as possible without being unattended, and it is an object of the present invention to propose a construction apparatus capable of improving the earthquake resistance during construction. It is what

<< Means for Solving the Problem >> The present invention provides a construction work space which is provided above a building to be constructed and in which standing construction of a main pillar and other construction work are performed between the construction below the construction. And a column structure that is detachably supported by the building and is erected upright, and a column structure that is provided in the beam structure and is detachably locked to the column body to hold it in the structure. Equipped with lifting lock means that is released and raises the beam structure along the pillar to form a construction work space with the building, and construction means provided in the beam structure and performing construction work in the construction work space It is characterized by that.

Further, the present invention is characterized in that, in the above-mentioned configuration, the beam structure has a cover portion that covers the construction work space.

Furthermore, the present invention is characterized in that, in the above-mentioned structure, the columnar body has a rack portion, and the lifting locking means has a pinion.

<< Operation >> To describe the operation of the present invention, the lifting lock means provided in the beam structure is locked to the pillar supported by the building, whereby the beam structure is firmly held above the building. To be done. Since the ascending locking means and the pillar are in a locking relationship, sufficient seismic strength can be ensured even during construction, and seismic resistance can be improved.

And by releasing the lifting lock means from the pillar,
The beam structure is lifted along the pillar to form a construction work space between it and the building, and once the construction work space is formed, the pillar is again locked with the lifting lock means. . That is, the pillar body functions as a pillar that forms a construction work space by being locked with the lifting lock means. Here, the main construction pillar is erected by the construction means in the formed construction work space, integrated with the main construction pillar in advance, or a beam is attached by retrofitting, and these are fixed. And by repeating this work for all main columns and main beams,
All the main columns and main beams will be constructed in the construction work space that forms the floor, so that the floor of the building can be constructed.

When the construction work of the height floor is completed, the beam structure is then raised again by the lifting and locking means, and the construction work above is further advanced.

That is, by repeating the raising and locking of the beam structure by the pillars and the lifting and locking means, the construction work can be sequentially advanced upward while securing the construction work space. When constructing means above the construction work and installing construction means in the beam structure that is always located in the construction work space and proceeding with the construction work, we will automate the raising control of the beam structure, drive control of the extension means, and control of the construction means. It is easy to introduce and is suitable for automation of construction work in combination with other automatic construction equipment.

In addition, since the construction work space is shielded from the outside by the cover provided on the beam structure, there is no inconvenience that the construction work depends on the weather, and the construction work can be carried out without disturbing the surrounding environment. .
