Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a saving device that can be preferably applied when constructing various buildings ranging from low-rise to high-rise buildings without requiring human labor (that is, unmanned as much as possible). This is about humanized construction equipment.

(Conventional technology) In general, construction of various buildings such as medium-to-high-rise buildings is carried out by building columns up to the top floor and then sequentially pulling up and installing slabs assembled on the ground using a winch, or by lifting the frame members using a crane, etc. This is done by building each floor one floor at a time from the lower floor to the upper floor and stacking them up.

FIG. 5 is for explaining the latter method, and this figure shows that the first and second floors have already been constructed and the third floor is being constructed. In other words, a worker H gets on the floor of the third floor and lifts the frame member S by a crane C.
Then, they would be attached to the third floor at a predetermined location using welding, bolts, or other means.

In addition, recently, in a plant installed on the first floor above ground, a one-story building is intensively constructed using machines such as robots, and after the construction of the first floor is completed, the building will be raised upward by the floor height. A method has been proposed in which the entire building is constructed by repeating this process (see Japanese Patent Laid-Open No. 62-244941).

(Problems to be Solved by the Invention) However, the above-mentioned method of pulling up and attaching the slab with a winch after constructing columns up to the top floor, and the method of constructing each floor from the lower floor to the upper floor, both require a large number of methods. Requires manpower,
The work was affected by the weather and had significant restrictions on work hours, often resulting in an extension of the construction period, and required great consideration for the safety of the workers.

In addition, although the previously proposed method eliminates this problem to a large extent, it also
That is, there was a problem in that there was a limit to the height of the building due to the strength of the members to be pushed up.

Furthermore, as construction progresses, the height of the building becomes considerably higher and the weight becomes heavier. There was a risk that the structure would become unstable, and there were problems with earthquake resistance during construction.

The purpose of the present invention is to solve the above-mentioned problems and to propose a construction device that can be preferably applied when constructing various buildings from low-rise to high-rise buildings as unmanned as possible, and can improve seismic resistance during construction. That is.

(Means for Solving the Problems) The present invention provides a construction work space that is provided above a building to be constructed, and in which construction work such as erection of main pillars is performed between it and the structure below. A beam structure is formed, a pillar body is erected while being removably supported by a building, and a pillar body is installed on the beam structure and is removably locked to the pillar body in order to hold it in the building and is released. and a lifting locking means for raising the beam structure along the column body to form a construction work space between the beam structure and the building, and a construction means provided on the beam structure for performing construction work within the construction work space. It is characterized by

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

Furthermore, in the above structure, the present invention is characterized in that the column has a rack portion and the upward locking means has a pinion.

(Function) Regarding the function of the present invention, the lift locking means provided in the beam structure is locked to the column supported by the building, thereby firmly holding the flexible structure above the building. be done.

Since this upward locking means and the column are in a locking relationship,
Sufficient seismic strength can be secured even during the construction stage, and earthquake resistance can be improved.

Then, by releasing the upward locking means from the column,
The flexible structure is raised along the column to form a construction work space between it and the building, and once this construction work space is formed, the lift locking means is again locked to the column. That is, the column functions as a column that forms a construction work space by being locked with the upward locking means. Here, a permanent column is erected by the construction means in the formed construction work space, and a beam is attached to the main column by integrating it in advance or by retrofitting, and these are fixed. By repeating this work for all the main pillars and main beams, all the main pillars and main beams will be constructed within the construction work space that forms the relevant floor. can be constructed.

Once the construction work on the floor at the relevant height is completed, the beam structure is raised again using the lifting locking means, and the construction work on the upper part is continued.

In other words, by repeating the raising and locking of the beam structure using the pillars and the lifting locking means, construction work can proceed upwards in sequence while securing the construction work space. When constructing work upwards and proceeding with construction work by installing construction means on the beam structure that is always located in the construction work space, it is necessary to automate the lifting control of the beam structure, the drive control of the extension means, and the control of the construction means. It is easy to introduce and suitable for automating 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, the inconvenience of having construction work affected by the weather is eliminated, and construction work can be carried out without disturbing the surrounding environment. .
