【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is a plan view of the assembly type water tank according to the present invention, FIG. 2 is an exploded perspective view of the main part, FIG. 3 is a sectional view taken along line II-II of FIG. 1, and FIG. 4 is III-III of FIG. FIG. 5 is a sectional view taken along the line, and FIG. 5 is an enlarged sectional view of the same portion.

In FIG. 1, reference numeral 1 denotes an assembled water tank according to the present invention, which is an embodiment of a water tank in which two tanks 1A and 1B having the same shape are formed in parallel, and an outer peripheral side wall 2A, a partition side wall 2B and this side wall 2B. It is formed of a bottom plate 3 surrounded by side walls 2A and 2B.

Numeral 4 is a pillar block used at the corners of the side walls 2A and 2B, and as shown in FIG. 2, it has a square bottom plate 5 and a protrusion 6 having a cross-shaped cross section which is erected above it. The joint side end surface 6a of each protrusion 6 is formed so as to be flush with the joint end surface 5a of the bottom board 5. The column portion 7 is formed with lateral holes 8a and 8b penetrating between the projecting portions 6 and 6 facing each other. The lateral holes 8a and 8b orthogonal to each other are formed in the column portion 7. It is formed in a vertically shifted position so as not to intersect with each other inside.

Reference numeral 9 denotes a side wall block used as the side walls 2A and 2B. As shown in FIG. 2, the side wall block 9 is composed of a rectangular bottom plate portion 10 and an upright wall portion 11 standing upright there. A lateral hole 12 penetrating between the joint-side end faces 11a of the wall portion 11 is formed at a position facing the lateral hole 8a or 8b formed in the support block 4. Further, the reinforcing bar 13 disposed inside the side wall 10a of the bottom plate 10 projects in a horizontal state. In the side wall block used as the outer peripheral side wall 2A, only one side end surface 10a is provided. Also, in the case of being used as the partition side wall 2B, the reinforcing bars 13 are projected on both side end faces 10a.

In the figure, 14 is a PC steel rod inserted into the lateral holes 8a, 8b, 12; 15 is a nut for tensioning and fixing the PC steel rod 14; 16 is an assembled rebar in the bottom plate 3; 17 is cast-in-place concrete, 18 is cobblestone, and 19 is foundation.

Therefore, when the water tank 1 is constructed, as shown in FIGS. 3 to 5, first, the stones 18 are laid at the place where the water tank 1 is to be installed, and a leveling concrete is laid on the top of the stones 18 to form the foundation 19 The pillar blocks 4 are installed on the foundation 19 at the corners of the water tank 1 and at the connecting portions with the outer peripheral side wall 2A of the partition wall 2B. Next, a plurality of side wall blocks 9 are arranged between the pillar blocks 4, and the joint side end surfaces 11a of the side wall blocks 9 and the joint side end surfaces 11a and the joint end surfaces 5a and 6a of the pillar blocks 4 are respectively arranged. The outer peripheral side wall 2A and the partition side wall 2B are formed by interview. At this time, a joint gap 20 having a predetermined width is formed between the blocks in order to secure the degree of freedom of the connecting portion.

Then, when the PC steel rod 14 is inserted into the lateral holes 8a, 8b, 12 of the blocks 4, 9 and connected, the PC steel bar 14 is formed on the exposed end surfaces 5a, 6a of the support block 4 only. A nut 15 is screwed into the protruding end of the rod 14 and temporarily fixed, and then a joint frame is applied to the joint gap 20 between the blocks 4 and 9 to fill the joint concrete. After hardening to some extent, the PC steel rod 14 is tensioned to connect the blocks 4 and 9 together.

Next, the rebars 16 for the bottom slab 3 that have been assembled in advance to the required dimensions are placed on the bottoms of the tanks 1A and 1B surrounded by the side walls 2A and 2B, respectively, and the ends of the rebars 16 are assembled. The reinforcing bars 13 projecting from the bottom plate portion 10 of the side wall block 9 are joined by welding or superposition. Then, concrete 17 is cast from above the assembled rebar 16 to form the bottom slab 3 integrated with the side wall block 9. Then, if necessary, the joint between the blocks 4 and 9 is subjected to resin caulking for finishing.

[0013]

[Effects of the Invention] Since the present invention is configured as described above, it can be constructed with only a small number of parts, that is, a pillar block and a side wall block, so that product management and assembly are possible. While the work can be done efficiently, it is possible to construct aquariums of different sizes freely by combining them. Further, since the column block having the above-mentioned structure is arranged at the connection portion at the corner portion of the side wall block, there are various effects that the structural strength is large and the durability is high.
