Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents the basic structure of a corrugated sheet structure, particularly the basic concrete block from being divided due to the corrugated sheet structure, and exerts the proof strength of the basic concrete block sufficiently. The present invention relates to a basic structure of a corrugated plate structure that is made possible.

[0002]

2. Description of the Related Art Conventionally, for example, when a warehouse is constructed on the ground by a corrugated plate made of a steel corrugated plate as shown in FIG. The structure was as follows.

As shown in FIG. 8, a hole is previously dug in the ground,
The end portion of the arc-shaped corrugated sheet 1 forming the corrugated sheet structure is put in this hole, and concrete 2 is placed in the hole. Hereinafter, it will be referred to as Prior Art 1.

As shown in FIG. 9, a plate 3 is welded to an end face of an arcuate corrugated plate 1 constituting a corrugated plate structure, and the plate 3 and a base 4 fixed to the ground are bolted. Hereinafter, it will be referred to as Prior Art 2.

However, the prior art 1 shown in FIG.
Work such as placing concrete 2 in the hole and corrugated corrugated plate 1
Since it is necessary to perform the assembling work at the same time, the work becomes complicated. In particular, if the structure becomes large, temporary construction is required, which increases construction costs. Moreover, if rainwater accumulates in the previously dug hole, it takes time and effort to drain it.

According to the prior art 2 shown in FIG. 9, in order to make the plate 3 resistant to an external force acting in the longitudinal direction of the arc-shaped corrugated plate 1, the plate thickness of the plate 3 is set to be smaller than that of the corrugated plate 1. Since the plate 3 needs to be made considerably thick and the plate 3 needs to be welded over the entire length of the end face of the corrugated plate 1, the construction cost is increased.

Therefore, as shown in FIG. 10, a lower part of a corrugated plate-shaped fixing member 6 having the same cross-sectional shape as the arc-shaped corrugated plate 1 is embedded in a basic concrete block 5 buried in the ground, and the corrugated plate is fixed to the fixing member 6. There is a basic structure consisting of bolting the lower part of 1. Hereinafter, this basic structure is referred to as Prior Art 3.

[0008]

However, the above-mentioned prior art 3 has the following problems. That is,
Since the lower part of the corrugated plate-shaped fixing member 6 is embedded in the basic concrete block 5, the basic concrete block 5 is divided by the fixing member 6. Therefore, the strength of the basic concrete block 5 is reduced, and the proof stress necessary for fixing the fixing member 6 cannot be secured. In order to secure the necessary proof stress, it is necessary to increase the size of the basic concrete block 5. It was

Therefore, an object of the present invention is to prevent the basic concrete block from being divided so that the basic concrete block can have a sufficiently high strength without increasing the size of the basic concrete block. To provide the basic structure of a product.

SUMMARY OF THE INVENTION The present invention is a foundation structure for constructing a corrugated sheet structure on the ground, in which a foundation concrete block buried in the ground and an upper portion from above the foundation concrete block. The projecting, lower part is composed of a plurality of fixing members embedded in the basic concrete block, the fixing members are spaced apart from each other at positions corresponding to the flanges of the corrugated plates constituting the structure, It is characterized in that it is fixed in two rows along the corrugation direction.

Another feature of the present invention is that the fixing member of one row is fixed to the outer surface of one flange of the structure, and the fixing member of the other row is fixed to the other flange of the structure. It is fixed to either the inner surface or the outer surface.

Still another feature of the present invention is that the fixing member of one row is fixed to the inner surface of one flange of the structure, and the fixing member of the other row is the other flange of the structure. It is fixed to either one of the inner surface and the outer surface.

[0013]

When the lower part of the fixing member to which the lower part of the corrugated plate structure is bolted is embedded in the foundation concrete block, the fixing member such as grooved steel or L-shaped steel is used for the corrugated plate structure. By embedding the flanges at positions corresponding to each other at intervals, the foundation concrete block is not divided by the fixing member. Therefore, without increasing the size of the basic concrete block,
The foundation concrete block can have sufficiently high strength.
