Description

Description: TECHNICAL FIELD The present invention relates to a prefabricated water tank such as a water tank, and more particularly to a prefabricated water tank having a reinforced side wall.

(Prior Art) In a prefabricated water tank having a ceiling wall, a side wall, and a bottom wall formed by joining together a large number of unit plates having joint edges standing around the four sides of a right-angled quadrilateral substrate, supporting a load acting on the side wall. For this reason, it is known to attach a press or stay inside the water tank to reinforce the side wall, but in this case, there is a problem that members of the press or stay become an obstacle during repair or cleaning. Also,
It is known that a pillar having a length from the upper end to the lower end of the side wall is provided on the outside of the side wall, and the supporting pillar and the joining edge of the unit plate forming the side wall are fixed to each other by using a fixing piece. The column extending from the bottom to the lower end is heavy, and it is difficult to carry the column to the assembly site of the water tank, and moreover, it is troublesome to fix the column and the unit plate.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned conventional problems, in which the bonding edge of the unit plate in which the bonding edges are erected on the four circumferences of the right-angled quadrangular substrate is provided outside the water tank. In an assembled water tank that is connected to each other to form a side wall, one side of the angle member is fixed to the outside of the side wall over the entire length in the vertical direction of the joint edge of the unit plate, and the other piece of the angle member protrudes from the joint edge. Let me meanwhile,
The webs of long-shaped members having a U-shaped cross section having long-sided flanges and short-sided flanges are superposed and fixed with bolts to form an external reinforcing member, and the length of the substantially U-shaped member of the external reinforcing member is increased. The side flange portion is brought into contact with the other side of the angle member, and the long side flange portion is stuck out from the other side of the angle member over substantially the entire length in the up-down direction of the angle member to form a long side flange portion of the external reinforcing member. By fixing the unit plate to the inside of the water tank, eliminating the members that interfere with cleaning such as breaths and stays, the cleaning work inside the water tank is facilitated, and the external reinforcing material is divided to make it easier to carry it into the water tank assembly site. Further, the external reinforcing member and the side wall can be easily fixed to each other so that the assembly can be done without trouble.

(Example) Hereinafter, a specific structure of the present invention will be described based on an example shown in FIGS.

FIG. 1 is a vertical sectional view showing an assembled water tank of the present invention, FIG. 2 is a II-II sectional view of FIG. 1, FIG. 3 is a III-III sectional view of FIG. 1, and FIG. IV-IV sectional drawing of a figure, FIG. 5 is a partial perspective view which shows the reinforcement structure of the side wall upper part of this invention, and FIG. 6 is a longitudinal sectional view which shows another Example of this invention.

In FIGS. 1 to 4, reference numeral 1A is a side wall unit plate, in which joint edges 12 are provided upright on the four circumferences of a right-angled quadrangular substrate, and the joint edges 12 of the unit plates 1A are connected to each other toward the outside of the water tank. Form the side wall.

1B and 1C are unit plates for ceiling wall and bottom wall, respectively,
The ceiling wall and the bottom wall are formed by connecting the joining edges standing on the four sides of the rectangular board to each other.

On the outside of the side wall, the joining edge 12 of the unit plate 1A forming the side wall is formed.
One side of the angle member 2 is fixed over substantially the entire length in the vertical direction, and the other piece of the angle member 2 is projected from the joint edge 12.

Reference numeral 3 denotes an external reinforcing member, which is formed by stacking webs of long-shaped members having a substantially U-shaped cross section and fixing them with bolts 4.
The elongate mold member of the external reinforcing member 3 has a long side flange portion 31a and a short side flange portion 31b. That is, the long side flange portion 31a is formed longer than the short side flange portion 31b. The external reinforcing material 3
The long side flange portion 31a is brought into contact with the other side of the angle member 2 and the long side flange portion 31a is extended from the other side of the angle member 22 over substantially the entire length in the vertical direction of the angle member 2. The projecting portion of the long side flange portion 31a and the unit plate 1A are fixed to each other by bolts. In this way, since the projecting portion of the long side flange portion 31a and the unit plate 1A are fixed to each other with the bolt 5,
Since the bolt 5 can be easily fastened and the bolt 5 can be fastened at any place, the short side flange portion 31b of the outer reinforcing member 3 is formed shorter than the long side flange portion 31a. It does not get in the way when the bolt 5 is fastened. As described above, since the external reinforcing member 3 is formed by bolt-bonding a mold member having a substantially U-shaped cross section, the external reinforcing member 3 can be divided and carried into the assembly location of the water tank, and the workability is greatly improved.

The external reinforcing member 3 can be further divided and carried into the assembly location of the water tank when joined at the intermediate portion as shown in the figure, and the external reinforcing member 3 has a thicker plate at the lower portion where a large water pressure is applied. Since it is possible to use the mold material and use the external reinforcing member 3 having a thin plate thickness on the upper portion where the applied water pressure is small, the cost can be reduced, which is preferable. In order to join the upper part and the lower part of the external reinforcing material 3, the external reinforcing material 3
The flat plates 6 and 7 may be brought into contact with and fixed to the web and the brim portion. If the joining portion of the external reinforcing material 3 is the joining portion of the four unit plates, the bending at that portion becomes large, so that the joining of the external reinforcing material 3 is performed at the upper position of the unit plate 1 as illustrated.
It is better to join at the middle part of A.

At the lower end of the external reinforcement member, as shown in FIG.
The lower contact plate 32 is provided with a long hole 33 in a direction orthogonal to the projecting direction of the joint edge 12 of the unit plate 1A, and the bolt 8 is passed through the long hole 33 to mount the frame. It is fixed to 9. When the long hole 33 is formed in this manner, the pedestal 9
This is preferable because it absorbs the dimensional error of and the construction becomes easy.

FIG. 5 shows a fixing structure for the upper part of the external reinforcing member 3, and a contact plate 34 is fixed to the upper and upper ends of the external reinforcing member 3, and the upper contact plate 34 and the joint edge 12 of the side wall unit plate 1A are connected to each other. Ceiling unit board 1
The upper surface of B is fixed by the upper fixing plate 10. It is more preferable to fix the upper part of the external reinforcing member 3 to the upper part of the side wall in this way because the reinforcement becomes strong.

The external reinforcing member 3 of the present invention may not be connected at the intermediate portion as shown in FIG.

(Effects of the Invention) According to the present invention, since the side wall is reinforced by the external reinforcing material, a member for obstructing cleaning such as a breath or a stay is eliminated inside the water tank to facilitate the cleaning work inside the water tank. The external reinforcing material can be divided and carried into the assembly location of the water tank.Furthermore, the long side flange of the substantially U-shaped external reinforcing material is brought into contact with the other side of the angle material, and the upper and lower sides of the angle material are Direction, the long side flange is projected from the other side of the angle member, and the projecting part of the long side flange and the unit plate are fixed with bolts, so the long side flange and the unit plate are fastened with bolts. In addition, the bolt fastening can be performed at any place, and the short side flange portion of the external reinforcing material is formed shorter than the long side flange portion. It does not get in the way when bolting the unit plate There are various advantages such as.
