Description

[Detailed Description of the Invention] The present invention relates to an assembly structure of a corner portion of a liquid tank that is strong and durable without liquid leakage.

In recent years, instead of expensive and heavy stainless steel plates for liquid tanks, such as chemical tanks, hard synthetic resin panels such as vinyl chloride, which are relatively cheap, lightweight, and have excellent chemical resistance and durability, are being used. It is starting to form.

Therefore, in order to facilitate the assembly work of chemical tanks using such synthetic resin panels and to improve the joint strength at the same time, the applicant has proposed a design that allows assembly by inserting the side edges of the panels in directions orthogonal to each other. A panel joint was proposed in Utility Application No. 56-189557 (Utility Model Application No. 58-93135), but such a panel joint is extremely effective when connecting two panels perpendicular to each other. but,
At the corners where three panels are perpendicular to each other, as shown in Figure 7, the three joints connecting the panels get in the way, making it impossible to connect the joints in close contact with each other. First, there is a problem in construction that another backing member must be used, or a joint must be used only to connect the side walls of the panel, and the bottom wall of the panel must be attached to the bottom surface of the joint.

However, the assembly structure of the present invention solves the above-mentioned problems and provides a strong and durable assembly structure with little leakage.

The preferred embodiment will be described below with reference to the accompanying drawings, but in order to facilitate understanding, each necessary component will be explained first.

FIG. 1 shows an example of a corner panel joint, and this joint A has a pair of panel side edge insertion grooves 1 and 2 that are orthogonal to each other, sandwiching a central hollow spacer portion 3, and further includes The ends 1a, 2a of the respective grooves 1, 2 are panel insertion openings 1c, 2.
The slanted notch ends 4 and 5 are cut away from the c side toward the top part 3b of the spacer part 3 so as to form an angle α of 45 degrees.

The center spacer part 3 is hollowed out in the center to form a hollow part 3a in order to reduce material costs and weight, but even if it is a solid body, it does not affect the assembly structure of the present invention in any way. do not have.

By the way, the corner panel joint A having such a unique shape is made by extrusion molding of hard vinyl chloride or the like, and as shown in FIG. After forming the joint 6 having the insertion grooves 1 and 2, as shown in b, one end of the joint 6 is shaped along the respective planes formed by the broken lines X, Y and X', Y' at an angle α of 45 degrees. It is formed by cutting the grooves 1 and 2 and the spacer portion 3.

In the embodiment shown in FIG. 1, the inner side pieces 1d and 2 of each of the grooves 1 and 2 are
By making the panel d extend slightly longer than the outer side pieces 1e and 2e and by tilting it slightly inward with respect to the insertion direction of the panel B (not shown in FIG. 1), the panel It serves as a guide when inserting panel B, making it easier to insert panel B, and also easily dealing with slight errors in the thickness of panel B, so that panel B can be placed snugly into the grooves 1 and 2. Efforts have been made to enable insertion and attachment, but on the contrary, the outer side pieces 1e and 2e may have a similar configuration.

Furthermore, in order to better cope with errors in the thickness of the panel B, either one of the inner side pieces 1d, 2d or the outer side pieces 1e, 2e may be made thinner than the other so that it can be easily deformed. , and the right angle part in the grooves 1 and 2 and the inner side piece 1 as necessary.
Grooves (not shown) may be formed on the inner surfaces of d, 2d and the outer side pieces 1e, 2e to effectively prevent the occurrence of cracks or to make them easier to bend elastically. (None of the above are shown).

On the other hand, panel B, which is used in combination with the corner panel joint A described above to form the side wall and bottom wall of the liquid tank, is selected as appropriate depending on the purpose of use. When forming a chemical tank used in Composite panel with 7b and 7b
B ₁ is used. Additionally, hard vinyl chloride veneers are used as panels in chemical tanks that are used at room temperature. Furthermore, when forming an ordinary liquid tank such as an aquarium, various types of panels are used that have a strength that will not cause damage.

Therefore, in order to form the assembled structure of the present invention using such structural members, first, the bottom wall panel is assembled.
Insert both side edges B ₂ of B' into the grooves 1 of the two corner joints A' and A'' (see Figure 4), and then insert the side edges B 2 of the side wall panel B into the grooves 2 of one joint A'. Insert the side edge B ₂ of the other side wall panel B into the groove ₂ of the other joint A'' (see Figure 5).
and insert the vertical side edges B2 of each side wall panel B'', B into the grooves _1, 2 of the third corner joint A, and then insert the three corner joints A', A. '', A are pressed against each other from three sides to bring the inclined notch ends 4, 5 of the joint A into close contact with each other, thereby forming each panel B', A as shown in FIG.
A corner structure is assembled in which B'' and B are inserted so as to extend across the respective grooves 1 and 2 of the adjacent joints A', A'' and A.

After assembling the liquid tank having such a corner structure, the grooves 1 and 2 and the panel B are bonded with adhesive as necessary, and the inner pieces 1d and 1d of the grooves 1 and 2 are attached.
2d and the tips of the outer side pieces 1e, 2e and the surface of the panel B are welded with a vinyl chloride welding rod to form a seal part, and at the same time, the inclined notched ends 4, 5 of the joint A are joined at the corner parts. By welding the bonding surfaces of panels B with vinyl chloride, a liquid tank is obtained in which the bonding strength between panels B is maintained at the joint, and the watertightness is reliably maintained at the sealed portion.

As detailed above, the assembly structure of the present invention consists of three
The difference between each panel joint for book corners is that it is formed simply by inserting the side edges of the panel into the grooves and then joining and fixing the slanted notched ends of the joints to each other from three sides, so the workability is extremely good. be.

In addition, since the side edges of each panel are inserted in such a way that they extend across the grooves of the adjacent joints, the joints at the corners are strong, and unique effects such as no leakage are achieved. .
