In particular, it relates to the improvement of the combination structure.

[0002]

2. Description of the Related Art As a conventional tank, for example, 1 m × 1
m, a joining edge is provided on the periphery of the pressure receiving surface formed in a square,
Using a plurality of panels integrally molded from synthetic resin such as RP, the joining edges of the panels are joined together with bolts and nuts via packing using a plurality of panels, and the bottom wall, side walls and roof of the tank are assembled to form a box. We make body containers. In particular, in a dedicated tank for storing drinking water, in order to facilitate inspection of the bottom wall, generally two or more rectangular parallelepiped cloth foundations made of concrete are arranged on the ground in parallel with each other. The gantry is constructed by hanging steel beams on the upper surface of the foundation.

FIGS. 8 to 1 show the structure of a conventional gantry.
2 is a sectional view showing a state where the tank 1 is installed on a conventional gantry 5c, and FIG. 9 is a perspective view of the gantry 5c. In FIG. 9, the orthogonal main beams 8a and 8b and the auxiliary beams 10a and 10b of the gantry 5c are orthogonal to each other in accordance with the width of the joining edge of the bottom wall panel 14, and are assembled in a crossbeam to support the bottom wall 3 of the tank. I have to.

[0004] The steel material constituting the gantry 5c can be roughly classified into three types. That is, orthogonal main beams 8a and 8b which are channel steels arranged orthogonally to the cloth foundation 11
A parallel main beam 9 which is a channel steel which is arranged in parallel with the cloth foundation 11 and serves as a frame material of the gantry 5c; and auxiliary beams 10a and 10b which are arranged in parallel with the cloth foundation 11.

Here, the orthogonal main beams 8a, 8b and the auxiliary beams 10a, 10b are generally fastened by the following method. This will be described below with reference to FIG. 10 which is a cross-sectional view taken along the line AA of FIG. 9 and FIG. 11 which is a cross-sectional view taken along the arrow B of FIG. (1) A gusset plate 13 made of a steel plate having bolt insertion holes provided on one side surface of the orthogonal main beam 8b and both side surfaces of the orthogonal main beam 8b is orthogonally welded,
(2) Auxiliary beams 10a provided with bolt insertion holes at both ends in advance,
The bolt insertion holes 10b are aligned with the bolt insertion holes of the gusset plate 13 and fastened and fixed with bolts 17a. The orthogonal main beams 8a and 8b and the parallel main beam 9 are similarly fastened via welded gusset plates.

[0006]

Problems to be Solved by the Invention There are the following problems in the above-mentioned conventional gantry, and improvement thereof has been desired. (1) Due to the welding work of the gusset plate 13, heat is generated in the orthogonal main beams 8a and 8b and the parallel main beam 9 by heat, and the shape of the gantry is twisted, so that the bottom wall 3 of the tank is distorted, and May cause leakage. (2) The work of welding the gusset plate 13 requires skill and is relatively dirty, and is often disliked by workers. For this reason, there is a shortage of workers and a long time is required for production. (3) Each time a gantry having the same size as the bottom surface is manufactured according to the shape of the bottom surface of the water tank, the operation becomes complicated and expensive. (4) As shown in FIG. 12, the side wall panel 1 on the gantry 5c
6 and the upright joint edge of the bottom wall panel 14
When assembling the tank by fastening, there is no gap between the cloth foundation 11 and the parallel main beam 9, as shown in FIG. Can not. For this reason, the bottom wall panel 14 and the side wall panel 1
When tightening the bolt 17b for fastening the bolt 6, the bolt fastening operation is difficult, and much labor and time are required.

The present invention has been made in view of the above problems, and has as its object to provide an inexpensive tank base that can be easily manufactured in a short period of time and that does not generate distortion due to heat. It is.

[0008]

The configuration of the present invention for achieving the above object will be described with reference to FIGS. 2, 3 and 7 corresponding to the embodiments. On a plurality of cloth foundations (11), foundation bolts (12)
In the gantry (5a) of the tank fixed by the above and combined in a cross-girder shape by a plurality of beams made of shaped steel, a plurality of bolts in which bolt holes are provided in the web portion (20) in advance on the upper surface of the cloth base (11). The orthogonal main beam (8c) is arranged orthogonal to the cloth foundation (11) and parallel to each other.
Between the opposed web portions (20) of the
In addition to disposing the unit auxiliary beam (6a) provided with 9), the web portion (20) of the opposed orthogonal main beam (8c ) and the both ends bent piece (19) of the unit auxiliary beam (6a) are bolted (17c). ) To secure the unit auxiliary beam (6).
a) is on the vertical surface at both ends except for the bent piece at both ends (19).
A bolt insertion hole (18a) is provided.
a) and the cloth foundation (11) are fixed to a foundation bolt having a substantially L-shaped cross section.
The technical means fastened through the plate 7 is taken.

[0009]

The present invention eliminates the welded portion and tightens the bolts, and provides a gap between the upper surface of the cloth foundation and the lower surface of the auxiliary beam outside the gantry.
