Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an assembled liquid storage tank with a partition wall for a water receiving layer, etc., and in particular, the partition wall is strongly reinforced with a reinforcing material to eliminate the need for internal reinforcing material. The present invention also relates to a prefabricated liquid storage tank with a partition wall in which the upper part of the partition wall is strongly reinforced.

(Prior art and its problems) In a prefabricated liquid storage tank in which a ceiling wall, a side wall, and a bottom wall are constructed by interconnecting a large number of unit plates having bonding edges on the four peripheries of a right-angled substrate, bonding is made to the periphery. 2. Description of the Related Art A prefabricated liquid storage tank with a partition wall is known in which a partition wall is formed by connecting unit plates having edges to each other at their joining edges, and the partition wall is used to partition the inside of the tank.
In this case, it is known to install braces and stays inside the tank to reinforce the partition walls in order to support the load acting on the partition walls, but in this case, the braces and stays get in the way during repairs and cleaning. There was a problem. For this reason, partition walls are reinforced by fixing reinforcing materials to them, but this is especially true when the liquid volume on both sides of the partition wall is significantly different or when sudden loads are applied, such as during an earthquake. The upper part of the partition wall was not sufficiently reinforced, and there was a risk that the part would break if a large load was applied, such as during an earthquake.

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and involves attaching and fixing reinforcing sections to the joint edges in the vertical direction of unit plates for partition walls. Fixing one mounting piece of the substantially U-shaped upper fixture to the upper part of the profile, and fixing the other mounting piece to the partition wall unit plate,
On the other hand, on the other side of the partition wall unit plate, one side of the angular internal fixing plate is fixed to the partition wall unit plate, and the other side is fixed to the joint edge of the ceiling wall unit plate perpendicular to the partition wall, and the water tank is fixed. This makes internal repair and cleaning work easier, and the partition wall is strongly reinforced to prevent the upper part of the partition wall unit plate from being destroyed even if a large load is applied to it, such as during an earthquake. It is.

(Example) Hereinafter, the specific structure of the present invention will be explained based on the example shown in FIGS. 1 to 6.

FIG. 1 is a perspective view showing the assembled liquid storage tank of the present invention;
Figure 2 is a cross-sectional view showing part A in Figure 1, Figure 3 is a longitudinal cross-sectional view showing part B in Figure 1, Figure 4 is a cross-sectional view showing part C in Figure 1, and Figure 5 is a cross-sectional view showing part A in Figure 1. This figure is a longitudinal cross-sectional view showing section C in FIG. 1, and FIG. 6 is a longitudinal cross-sectional view showing section D in FIG.

In FIG. 1, reference numeral 1A denotes a unit plate for the ceiling wall, in which joint edges 1a are erected around the four peripheries of a right-angled rectangular substrate, and the joint edges 1a of the unit plates 1A are directed toward the inside of the tank and are connected to each other. It forms the ceiling wall.

Reference numeral 1B denotes a unit plate for a partition wall, and the upper unit plate 1B has joint edges erected on three sides, and the lower unit plate 1B has joint edges 1b erected on all four sides.
These joining edges 1b are joined together to form a partition wall, and the inside of the tank is partitioned by the partition wall. In addition, 1C is a unit plate for the bottom wall, and a joining edge 1c is set up around a rectangular substrate, and the unit plates 1C are joined together with the joining edge 1c facing downward to form the bottom wall. , the lower joint edge 1b of the partition wall unit plate 1B is coupled to the bottom wall unit plate 1C.

Reinforcing sections 2 are attached to both sides of the joining edge 1b of the partition wall unit plate 1B over almost the entire length in the vertical direction. As shown in the sectional view of FIG. 2, the reinforcing profile 2 has a mounting portion 21 to be attached to the joint edge 1b of the partition wall unit plate 1B, a flat portion 22 and a bent portion 23 continuing from the mounting portion 21. There is. By forming the bent portion 23, the section modulus is increased. The mounting part 21 of the reinforcing profile 2 is fixed to the joint edge 1b with bolts 3, and the flat part 22 of the reinforcing profile 2 is fixed to the joint edge 1b with bolts 3.
They are polymerized and fixed together with bolts 4.

A notch 24 is formed in the attachment portion 23 of the reinforcing profile 2, and the notch 24 is fitted so as to straddle the joining edge 1b in the left and right direction of the partition wall unit plate 1B. In this way, the reinforcing section 2 is attached and fixed over substantially the entire vertical length of the joint edge 1b of the partition wall unit plate 1B, thereby reinforcing the partition wall. At this time, as shown in the figure, the reinforcing sections 2 and 2 are connected to the flat part 22.
If they are joined together with bolts 4, even if a large load is applied to the reinforcing section 2 during an earthquake, the joints between the joint edges 1b of the partition wall unit plates 1B will expand, causing water to leak from the joints or break. There is no fear and it is suitable.

In the upper part of the reinforcing section 2, as shown in part B of FIG. 1 and FIG.
One mounting piece is fixed to the bent part 23 of the reinforcing frame 2, the other mounting piece is fixed to the partition wall unit plate 1B, and one side of the angular internal fixing plate 6 on the other side is fixed to the partition wall unit plate 1B. A unit plate 1 for a ceiling wall is fixed integrally with a bolt 7 passing through the unit plate 1B, and the other side of the angular internal fixing plate 6 is perpendicular to the partition wall.
It is fixed to the joint edge 1a of A. In this way, the load applied to the reinforcing section 2 can be transmitted to the ceiling wall, and the reinforcement of the upper part of the partition wall becomes strong.

At the lower part of the reinforcing profile 2, as shown in part C in FIG. 1 and in FIGS. At the same time as fixing to the plate 1B, an angular internal abutment plate 10 is brought into contact with the corner of the partition wall unit plate 1B and the bottom wall unit plate 1C on the other side, and one side of the angular internal abutment plate 10 is fixed to the plate 1B. Partition wall unit plate 1
B, and the other side is fixed to the bottom wall unit plate 1C. In this way, the joint between the joint edge 1b of the partition wall unit plate 1B and the bottom wall unit plate 1C is reinforced, and even if a large load is applied to the part during an earthquake, water will not leak from the part. This is preferable because it can prevent damage.

Further, as shown in part D in FIG. 1 and FIG. 6, a substantially U-shaped upper fixture 5 There is a substantially flat internal fixing plate 1 on the other side of the
1 is arranged, and the lower part of the substantially flat internal fixing plate 11 is fixed to the other mounting piece of the substantially U-shaped upper fixture 5 by bolts 12 passing through the partition wall unit plate 1B, and is fixed in a substantially flat plate shape. The upper part of the plate 11 is fixed to the joining edge 1a of the ceiling wall unit plate 1A, which is parallel to the partition wall. In this way, the upper part of the partition wall unit plate 1B is fixed to the joint edge 1a of the ceiling wall unit plate 1A, and can sufficiently withstand the pressing force acting in the direction perpendicular to the partition wall, so that the partition wall due to liquid pressure etc. This is preferable because it can prevent deformation and destruction of the material.

Note that 13 is a frame made of H-beam steel or the like that supports the liquid storage tank.

(Effects of the invention) According to the invention, since the reinforcing material is attached and fixed to the vertical joint edge of the partition wall unit plate to reinforce the partition wall, there are no stays, braces, etc. in the tank that will interfere with repair or cleaning. This eliminates the need for parts that become damaged, making repair and cleaning work easier. Also, one mounting piece of the substantially U-shaped upper fixture is fixed to the upper part of the reinforcing section, and the other mounting piece is fixed to the partition wall unit plate, while the other part of the partition wall unit plate is angled. Since one side of the shaped internal fixing plate was fixed to the unit plate for the partition wall, and the other side was fixed to the joint edge of the unit plate for the ceiling wall perpendicular to the partition wall, the upper part of the reinforcing frame was formed into a substantially U-shaped upper fixing member. is fixed integrally with the upper part of the partition wall unit plate,
The load applied to the reinforcing profile is transmitted to the upper part of the partition wall unit plate, making the reinforcement stronger.Furthermore, one side is fixed to the partition wall unit plate, and the other side is fixed to the ceiling wall unit plate perpendicular to the partition wall. The load is transmitted to the ceiling wall through the angled internal fixing plate fixed to the joint edge, so even if a load is applied in a direction perpendicular to the partition wall, water leakage or destruction is prevented from that part. There are various advantages such as:
