Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a structure such as a driving range, a stand for an event or a stadium, a parking lot or the like.

[0002]

2. Description of the Related Art Conventionally, a structure of this type is constructed by vertically connecting vertically standing steel frame columns in a girder direction and projecting a steel beam supporting the floor slab from the steel column. It had been.

[0003]

However, a steel frame structure of three stories or more requires a fireproof coating, has a design problem, and requires a lot of labor and time for assembling the steel members, so that the steel column and the floor slab are required to be assembled. There was a problem in the balance of stress of the propelled steel beam supporting it. The present invention has been proposed in view of the above problems of the prior art, and an object thereof is to provide a golf driving range, a stand for use in an event or a stadium, which is structurally advantageous and has an improved design and a shortened construction period. There is a point to provide a construction method of the structure.

[0004]

In order to achieve the above-mentioned object, according to the method of constructing a structure according to the present invention, P is formed on the foundation.
The Ca column is inclined at a predetermined angle, the column base is fixed by the steel rod anchored to the foundation, and the diagonal column is erected.
A PCa protruding beam is erected on the side opposite to the slanting direction of the same slanted column, and a PC steel material is inserted through the protruding beam and the column, and a tensioned and integrated frame is constructed. Frames are lined up at predetermined intervals, and PCs are installed between the frames.
A girder beam is disposed, and a floor slab is constructed on the projecting beam while inserting and tightening a PC steel material between each girder beam and each column.

[0005]

According to the present invention, as described above, the inclined PCa column is erected on the foundation, and the PCa ejection beam for supporting the floor slab is provided on the side opposite to the inclined direction of the PCa column. And P
PCa girder beams are arranged between Ca columns to form the structure of the structure. By making the columns oblique, the stress generated in the columns during long-term loading is reduced, and The rational design of the structure including is possible.

[0006]

The present invention will be described below with reference to the illustrated embodiments. The foundation pile 1 is placed, the foundation 2 is constructed, and the PC steel rod 3 is raised from the foundation 2. (See FIG. 1) Next, a PCa pillar 4 that is tilted outward at a predetermined angle is installed on the foundation 2 and is fixed by a PC steel rod 3 fixed to the foundation 2 to erect the oblique pillar. ,
The PC steel material extended from the foundation 2 is inserted into the PCa pillar 4 and tightened to erect the oblique pillar. (See FIG. 2) Next, on the inner surface of the PCa pillar 4, the PCa protrusion beam 5 is formed.
Install. At this time, the base end portion of the beam 5 is supported by the beam supporting notch 6 provided in the PCa column 4, and the free end of the beam 5 is supported by the support 7, and the beam 5 and the P
A PC steel material 8 is transversely passed through the Ca pillar 4 and tensioned to construct a frame in which the PCa protruding beam 5 and the PCa pillar 4 are integrated. (See FIG. 3) The frames are constructed in parallel or arcuately in parallel on a plane at a predetermined interval, and temporary brackets 9 are attached to the facing surfaces of adjacent PCa pillars 4, and the brackets are attached. A PCa girder beam 10 is bridged between 9 and the same girder beam 10 and the PC.
The girder beam is installed by inserting and tightening the PC steel material 11 across the a pillar 4. (See FIG. 4) In the figure, 10 'is a rising wall.

On the other hand, a half-PCa floor slab 12 is laid over the PCa projection beam 5 (see FIG. 5), and a slab concrete 13 is placed on the floor slab 12. (See FIG. 6) In addition, if necessary, at the lower end of the PCa protrusion beam 5, P
The strength can be further increased by laterally passing through and tensioning the PC steel material 8 ′ across the Ca columns 4. (Refer to FIG. 7.) The girder direction is affected by creep due to pre-stress stress, and due to drying and shrinkage.
Since the PCa bracket 14 is attached to the PCa pillar 4 via the PC steel rod 15 with an appropriate span, the RC beam 16 is mounted between the opposing brackets 14 to expand the expansion joint. Provide an int.
(See FIG. 8) FIG. 9 and FIG. 10 show bending moment distribution diagrams of the frame structure by the construction method of the above-mentioned embodiment in which the columns are inclined and the frame structure by the conventional method in which the columns are erected, respectively. As described above, according to the present embodiment, by sloping the column, the design of the column and the foundation of long-term stress by the canter lever is advantageous, and not only the stress of the column but also the stress in the column base can be reduced, and the overall Improves stress balance.

[0008]

As described above, according to the present invention, the pillars, beams, and floors of the structure such as the golf driving range, the stand of the event or the stadium, which are conventionally designed by the steel structure, are assembled into the precast concrete. By using the construction method, the conventional steel frame construction with three or more floors required a fireproof coating, which was problematic in design. According to the present invention, however, such a need is eliminated, the design is improved, and the construction period is increased. The floor vibration is shorter than that of the steel frame structure, and the dismantling is easier than that of the conventional RC structure.

Furthermore, by designing the column as a PCa sloping column and installing a protruding PCa beam on it, it is advantageous to design the column and foundation during long-term stress by the canister lever (20 to 30% compared to the conventional vertical column). Therefore, the stress in the column base can be remarkably reduced, and the stress balance is improved as a whole.
