[Industrial applications]

 The present invention relates to a tank mount, and more particularly to improvement of its combined structure.

[0002]

[Prior Art]

 As a conventional tank, for example, a joint edge is provided on the peripheral edge of a pressure receiving surface formed in a square of 1 m x 1 m, and a plurality of panels integrally molded with synthetic resin such as FRP are used to pack the joint edges of the panels. A box-shaped container is manufactured by joining the bottom wall, side wall, and roof of the tank by connecting them with bolts and nuts via the. Especially in a dedicated tank for storing drinking water, in order to facilitate inspection of the bottom wall, two or more rectangular parallelepiped cloth foundations, which are generally made of concrete, are placed on the ground in parallel with each other. Steel beams are hung on the upper surface of these cloth foundations to form a pedestal.

The structure of a conventional pedestal will be described below with reference to FIGS. 8 to 12. FIG. 8 is a sectional view showing a state in which the tank 1 is installed on the conventional pedestal 5c, and FIG. 9 is a pedestal. 5c is a perspective view of FIG. In FIG. 9, the orthogonal main beams 8a, 8b and the auxiliary beams 10a, 10b of the gantry 5c are orthogonal to each other according to the width of the joint edge of the bottom wall panel 14, and are assembled in a cross beam shape to support the bottom wall 3 of the tank. I am trying.

The steel material forming the frame 5c can be roughly classified into three types. That is, the orthogonal main beams 8a and 8b, which are channel steels arranged orthogonally to the cloth foundation 11, and the channel steels which are arranged parallel to the cloth foundation 11 and serve as a frame member of the frame 5c. A main beam 9 and auxiliary beams 10a and 10b arranged parallel to the cloth foundation 11.

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

[0006]

[Problems to be solved by the device]

 The conventional pedestal has the following problems, and its improvement has been desired. (1) Due to the welding work of the gusset plate 13, distortion due to heat is generated in the orthogonal main beams 8a and 8b and the parallel main beam 9, and the bottom wall 3 of the tank is distorted due to the twisting of the shape of the gantry. This could cause a leak. (2) Since the work of welding the gusset plate 13 requires skill and is relatively dirty, it is often disliked by workers. Therefore, the number of workers is insufficient and it takes a long time for production. (3) Since a pedestal of the same size as the bottom is manufactured each time according to the shape of the bottom of the water tank, it is a complicated work and expensive. (4) As shown in FIG. 12, when the lower part of the side wall panel 16 and the upright joint edge of the bottom wall panel 14 are fastened with the bolts 17b on the frame 5c to assemble the tank, as shown in FIG. Since there is no gap between the parallel main beams 9, it is impossible to put a hand from the outside of the gantry to the back side of the parallel main beams 9, that is, the inside. For this reason, when tightening the bolts 17b that fasten the bottom wall panel 14 and the side wall panel 16, the bolt tightening work is difficult and takes a lot of time and effort.

The present invention has been made in view of the above problems, and an object thereof is to provide an inexpensive tank mount that can be easily manufactured in a short period of time and that is free from distortion due to heat. It is a thing.

[0008]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to FIG. 4 corresponding to an embodiment. The present invention shows that a plurality of cloth foundations (11) arranged in parallel and facing each other are provided with a foundation bolt. In the tank frame (5a) fixed by (12) and combined in a cross beam shape by a plurality of shaped steel beams, a plurality of tank bases (5a) arranged orthogonal to the upper surface of the cloth foundation (11) and parallel to each other. Placing Daihiki (6a), which is an orthogonal main beam of a book, and joists (7), which are multiple parallel main beams, on the upper surface of this Daihiki (6a) at appropriate intervals in parallel with the cloth foundation (11), A technical means is employed in which the Daihiki (6a) and the joist (7) are fastened and fixed with bolts (17c).

[0009]

[Action]

 The welded part is eliminated and bolts are fastened, and a gap is provided between the upper surface of the cloth foundation and the lower joist surface outside the gantry.
