Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a prefabricated liquid storage tank, and in particular, it is composed of a side wall, a bottom wall and a ceiling wall, and a joint edge is erected on four sides of a right-angled quadrilateral substrate. Assembly type in which the joining edges of the unit plates are joined to each other so that the joining edges face downward to form a ceiling wall and / or a bottom wall, and the ceiling wall and / or the bottom wall are reinforced with a reinforcing material. Regarding the liquid storage tank.

(Prior art and its problems) Conventionally, an assembly type in which the joining edges of unit plates in which the joining edges are erected on the four sides of a right-angled quadrilateral board are joined to each other with the joining edges directed downwards to form a ceiling wall. In the liquid storage tank, in order to reinforce the ceiling wall, at the cross-shaped joint portion of the four unit plates of the ceiling wall, there is a notch sufficient to straddle the two joint edges of the adjacent unit plates. The joining edge of at least two unit plates adjacent to each other is joined by the reinforcing bracket made of a flat plate having a substantially U-shaped planar shape in which the width of the back portion of the notch is larger than the plate thickness. There is known a structure in which a reinforcing bracket is fixed so as to cross a cross-shaped joint portion of an edge so as to prevent deformation, breakage, and bending of a ceiling wall. (For example, Jikkou Sho57
In this case, it is known that the reinforcing brackets are integrally joined to each other at right angles to each other, but in the case of welded ones, it takes time to attach them to the joint edges of the four unit plates. It is inferior in workability and it is not satisfactory in terms of strength when it is connected by bolts.

The present invention has been made in view of the above-mentioned conventional points, and is composed of a side wall, a bottom wall, and a ceiling wall. In a prefabricated liquid storage tank in which the joining edges of the unit plates are connected to each other with the joining edges facing downward, a ceiling wall and / or a bottom wall are formed, and four unit plates of the ceiling wall and / or the bottom wall are provided. A first reinforcing member having a cutout portion that straddles the joint edge of the adjacent unit plate is attached and fixed directly or through the joint edge reinforcement member to the joint edge of A second reinforcing material having a cutout portion that straddles the first reinforcing material is additionally attached and fixed directly or through a joint edge reinforcing material to firmly reinforce the ceiling wall and / or the bottom wall.

(Embodiment) Hereinafter, a specific configuration of the present invention will be described based on an embodiment shown in FIGS.

1 is an exploded perspective view showing an essential part of FIG. 1, FIG. 3 is a partial perspective view showing another embodiment of the present invention, and FIG. 4 is a partial perspective view showing yet another embodiment.

As shown in FIG. 1, the assembly type liquid storage tank of the present invention comprises a side wall X, a ceiling wall Y and a bottom wall Z, and the ceiling wall Y is constructed by sequentially connecting a plurality of unit plates 1. . The unit plate 1 is provided with joint edges 2 erected on the four circumferences of the substrate, and the joint edges 2 are downwardly joined to each other to form a ceiling wall Y. The four unit plates 1 constituting the ceiling wall Y A first reinforcing material 3 is attached and fixed to the joint edge 2. As shown in FIG. 2, the first reinforcing member 3 is substantially L-shaped, has a length that straddles two adjacent unit plates 1, and is provided with a cutout 31. The notch 31 has a size that straddles the joining edge 2 of the adjacent unit plates 1,
Two joining edges 2 of the unit plate 1 joined to this are fitted.

Further, in FIG. 1, reference numeral 4 denotes a second reinforcing material, which is additionally fixed to the joint edge 2 in a direction orthogonal to the joint edge 2 to which the first reinforcing material 3 is additionally fixed. The second reinforcing member 4 is
As shown in FIG. 2, it has a flat plate portion for attaching to the joining edge 2 and a shape in which the lower portion following the flat portion is bent in a semicircular shape, and has a length that extends over two adjacent unit plates 1. And notch
41 is provided. On the opposite side of the second reinforcing member 4, a joint edge reinforcing member 6 such as a flat plate is additionally attached and fixed to the joint edge 2, and the reinforcing members 6 are connected and fixed to each other via the second reinforcing member 4. I am doing it. With such a configuration, the joint edge 2 is reinforced by the joint edge reinforcing member 6 having a flat plate shape, and the joint edge reinforcing members 6 having a flat plate shape are integrally connected and reinforced by the second reinforcing member 4. Therefore, it is preferable because the reinforcement becomes stronger.

FIG. 3 is a perspective view showing another embodiment of the present invention, in which the second reinforcing member 4 has a long length, is wider than the length of the joint edge 2, and protrudes from the end edge of the joint edge 2. The reinforcing effect of the joint edge 2 is improved, and when the elongated second reinforcing member 4 is inserted between the side walls X, the elongated second reinforcing member becomes a beam member. The ceiling wall Y is further reinforced. 42 is a bent rib, and the bent rib 42 is a notch
It is preferable that the second reinforcing member 4 is further reinforced by forming 41 so as to sandwich it.

FIG. 4 is a perspective view showing still another embodiment of the present invention, in which a wide flat plate-shaped joint edge reinforcing member 7 is additionally attached and fixed to the joint edge 2 to reinforce the joint edge 2. The first reinforcing member 3 is fixed to the joint edge 2 via the wide flat plate-shaped joint edge reinforcing member 7, and the wide flat plate-like joint edge reinforcing members 7 are joined together to form the first reinforcing member 3.
Are integrally connected and fixed via. The second reinforcing member 4 is fixed at the end of the wide flat plate-shaped joint edge reinforcing member 7, and the wide flat plate-shaped joint edge reinforcing members 7 are integrally connected and fixed. With such a configuration, the joint edge 2 is reinforced by the wide flat plate-shaped joint edge reinforcing material 7, and the wide flat plate-shaped joint edge reinforcing materials 7 are connected to each other by the first reinforcing material 3 and the second reinforcing material. Since it is integrally connected and fixed by means of 4, the reinforcement is further strengthened, which is preferable. Reference numeral 8 denotes a ceiling pillar, which supports a ceiling wall Y by standing in an appropriate place when the liquid storage tank is large.

As described above, the ceiling wall Y is attached to the first reinforcing member 3 and the second reinforcing member 4
Although the present invention is not limited to this, the present invention is not limited to this, and the joint edge 2 of the unit plate 1 is directed downward, and they are connected to each other to form the bottom wall Z, and the bottom wall Z is as described above. First reinforcement 3
The second reinforcing member 4 may be reinforced, and both the ceiling wall Y and the bottom wall Z may be reinforced with the reinforcing member 3 and the connecting member 4 as described above.

(Effects of the Invention) As described above, according to the present invention, the first cutout portion that straddles the joining edge of the unit plate adjacent to the joining edge of the four unit plates of the ceiling wall and / or the bottom wall is provided. The second reinforcing material, which is a separate body from the reinforcing material and the first reinforcing material and has a cutout portion that straddles the first reinforcing material, is joined to the joining edge to which the first reinforcing material is attached and fixed. Since it is attached and fixed to the joining edge in the orthogonal direction, there are advantages that the mounting work is easy and the workability is excellent, and the cross-shaped joint portions of the four unit plates are strongly reinforced.
