"Example" Hereinafter, the floor slab of the present invention and the method of constructing a floor slab using the same will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the floor slab of the present invention.

The floor slab 5 of this embodiment is a plate-shaped thing that is inserted into a pillar l of a building to form a floor. The through hole 5a through which the pillar l is inserted and the notch 5b are formed so as to penetrate through the floor slab in the thickness direction thereof.

The floor slab 5 is a flat slab-like plate member mainly composed of a precast concrete plate, and is shaped into a substantially rectangular shape to match the exterior of the building.

Near some of the four corners of this floor slab 5, through holes 5a or notches 5b are formed for inserting columns. These through holes 5a and notches 5b are set to have a shape that matches the cross-sectional shape of the pillar l.

Note 1 is a rod-shaped member inserted into the through hole 5a and notch 5b of the floor slab 5. Further, on the side surface of the pillar l at a predetermined height, there is a bracket as a receiving part for receiving the floor slab 5! a is formed. As shown in Fig. 3, this bracket la is installed near the upper end of the column l, and has a generally wedge-shaped cross section, with its tip facing downward. has been done.

Next, a method of constructing a floor slab for a building using the floor slab 5 of this embodiment will be described.

First, a foundation (not shown) including the pillar I is constructed at a location on the ground where the building is to be constructed.

Next, the above-mentioned lift is carried out by lifting means (not shown) such as a lifting machine.
Lift the floor slab 5 above the pillar! , ... the upper end of the floor slab 5
The floor slab 5 is lowered downward while facing each through hole 5a and notch 5b.

And, there are pillars in the through holes 5a,... of the floor slab 5! , ... and fit the column l into the notch 5b, and place the floor slab 5 on the bracket la shaped on the side of the column according to the floor height of the building, so that the surface of the floor slab 5 is Install it so that it is approximately horizontal to the ground.

After this, another column 1 is added on top of the column 1 to construct the upper part of the upper floor, and a floor section is constructed on this column 1 in the same manner as in the above process.

By repeating these steps, the floor of the building is constructed, and then walls and the like are installed to complete the building construction work.

According to the floor slab 5 of this embodiment and the floor construction method using the same, the following excellent effects can be achieved.

Since flooring over a relatively wide area can be constructed in a short period of time, the work process for constructing the flooring of a building can be simplified, making it possible to shorten the construction period and reduce work costs.

Existing pillars are constructed in advance on the ground where the building is to be constructed, and the floor slab 5 is built in using the existing pillars as the target for erection, thereby making it possible to easily construct the floor of the building.

Furthermore, since the size of the floor slab is set to be longer than one span of the columns, it is possible to construct the floor over a wide range with one lift.

Further, if the structure is such that equipment such as piping is provided in advance on the lower surface of the floor slab 5, the construction period required for piping work etc. can be shortened.

Since the bracket 1a provided on the column 1 is placed near the upper end of the column 1, when the floor slab 5 is inserted through it, the side surface of the column 1 does not rise up, making it easy to insert the bracket 1a. can.

Note that the floor slab of the present invention is not limited to the details of the above-mentioned embodiments, and other modifications are also possible.

For example, the setting positions of through holes and notches in the floor slab,
The number may be determined as necessary.

Further, the present invention can be applied even if the cross-sectional shape of the building is approximately circular. In this case, the shape of the floor slab is approximately circular in appearance, and the pillars are arranged almost continuously along the outer periphery of the floor slab, thereby achieving the same effect as in the embodiment described above.

Furthermore, it can also be applied to flat slabs.

"Effects of the Invention" The floor slab of the present invention is a plate-shaped thing that is inserted into the pillars of a building to constitute a floor part, and the floor slab has a length in at least one of the longitudinal direction and the width direction. The pillars are formed to have a length of at least one span, and the through-holes or notches through which the pillars are inserted penetrate through the floor slab in the thickness direction, making it easy to construct a building. By constructing an existing house in advance on the desired ground, and incorporating the floor slab using the existing pillars as the target of erection, it is possible to easily construct the floor of the building. Furthermore, since the size of the floor slab is set to be longer than one span of the columns, it is possible to construct the floor over a wider area with a single lift.

Moreover, the present invention. The method for constructing a floor using floor slabs is to construct the pillars that make up the building, lift the floor slab upwards using a lifting means, and insert the upper end of the pillar into each through-hole of the floor slab. Alternatively, lower the floor slab downwards while facing the notch, insert the column into the through hole or notch in the floor slab, and place the floor slab on the bracket formed on the side of the column to match the floor height of the building. Since we decided to install the floor slab so that its surface is approximately horizontal to the ground, we can construct the floor over a relatively wide area in a short period of time, which simplifies the work process for constructing the floor of the building. It is possible to shorten the construction period and reduce work costs.

Furthermore, since the floor slab can be installed quickly, the construction period can be shortened.
