Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a stop at the abutting points of three or more unit panels of a panel aquarium that is assembled by joining joint flanges formed on the periphery of the unit panels with bolts and nuts. It is related to water construction methods.

[Background technology]

Each flange of a unit panel that has joining flanges for installation on the four peripheries is joined together, an elastic material is sandwiched between the joined flanges, and the flanges are sequentially fastened by tightening them with bolts, nuts, etc., and multiple In panel aquariums in which the aquarium is constructed from unit panels, it has not been possible to completely prevent water leakage from between the joint flanges at the butt points of the unit panels. especially,
At the location where 3 to 4 unit panels are butted together, i.e. at the T-shaped section or at the cross section, there is a lack of accuracy in the assembly process, variations in the product during manufacturing, and it is also a location where the tightening force after assembly is difficult to act. Water leaks are likely to occur.

Conventionally, an elastic material 100 using a foam such as polyethylene or polypropylene or a rubber-like elastic body such as EPT rubber or neoprene rubber has been used to connect flanges 101, 102, 103, etc. as shown in FIG.
104 and tightened these three parts with bolts and nuts (not particularly shown) to prevent water from leaking. In order to enhance the water-stopping effect through the intervention of the elastic material 100, it is necessary to apply a high surface pressure of the elastic material 100 to the flanges to be joined even if the tightening force by bolts and nuts is small, and to prevent the elastic material from moving against the movement of the unit panel. 100 plastic deformation is small,
It is required that the surface pressure be restored and that the elastic material has little deterioration over time. However, since the conventional elastic material 100 has a particularly flat cross-sectional shape, the tightening force acts on the entire surface, causing flange deformation before high surface pressure can be achieved, making it unsatisfactory for use in panel aquariums. It was hot. In addition, products using foam initially exhibit high water-stopping properties even with a small tightening force, but due to deterioration over time, hardening and collapse of bubbles weaken the resilience, resulting in water leakage after use. In addition, the pressing process for steel panels in particular is longer than for FRP panels, resulting in large variations in dimensions, and these variations are concentrated at the cross section, causing problems such as poor surface pressure and cutting of the sealing material.

[Purpose of the invention]

The present invention was invented in view of the above circumstances, and exhibits a water-stopping effect over a long period of time.
It is an object of the present invention to provide a water-stopping construction method for a panel aquarium that has an excellent water-stopping effect at a location where four unit panels are butted together, that is, a T-shaped portion or a cross portion.

[Structure of the invention]

In order to achieve the above object, the present invention provides a water stop construction method for abutting points of three or more unit panels of a panel aquarium that is assembled by joining joint flanges formed on the periphery of the unit panels with bolts and nuts. An elastic material having ribs on both longitudinal sides and both surfaces is sandwiched between the flanges over substantially the entire length of the joint between the joint flanges, and along the joint flanges at the butt part of the panels, and on both sides of the elastic material. Short, closed-cell soft foam plates that fit between the ribs are sandwiched between the joint flanges, and the joint flanges are tightened with bolts and nuts.

〔Example〕

Preferred embodiments of the present invention will be described below based on the drawings from FIG. 2 onwards.

FIG. 2 is a cross-sectional view of the present construction method applied to the so-called cross section where the unit panels 1 to 4 are butted together, and the elastic material 5 and the independent A soft foam plate material 6 of air bubbles is interposed. The elastic material 5 is
As shown in FIGS. 3 and 4, ribs 5a, 5a are provided on both sides in the longitudinal direction. As the soft foam plate material 6, EPDM foam, polyethylene foam, polyvinyl chloride foam, etc. are suitable. The elastic material 5 is interposed over almost the entire length of the joint flange, and the soft foam plate 6 attached thereto is preferably placed in the bolt holes counting from the ends of the unit panels 1, 2 to 4, that is, the end of the joint flange. It is applied to the spot long enough to cover the first or second hole. The soft foam board 6 in FIG. 2 is applied from the end to the area beyond the first hole. Therefore, the fourth
As shown in the figure, a hole 6a is bored in the soft foam plate 6 corresponding to the first hole of the joining flange. This soft foam board 6 must extend along with the elastic material 5. 5 and 6 show modified examples of the elastic material 5. FIG. The soft foam board has a thickness of about 3 mm.

The above-mentioned elastic materials 5 that do not have ribs 5a, 5a or that use an elastic unvulcanized sealant as the elastic material 5 have been known in the past, but with such elastic materials, it is difficult to tighten bolts and nuts. The force causes deformation of the flange, and the surface pressure is low and water-stopping properties are poor. Particularly in those using elastic unvulcanized sealant, the movement of the unit panels 1, 2 to 4 or the tightening of bolts and nuts can cause plastic deformation. It has been difficult to maintain performance over time. In addition, if a material similar to the soft foam plate material 6 is sandwiched between joint flanges alone, it will harden over time, and it will not be possible to obtain high surface pressure with a small tightening force, which is a characteristic of the foam, but after deterioration over time. In addition, it became impossible to respond to the movements of the unit panels 1, 2 to 4.

In the present invention, as described above, an elastic material 5 made of vulcanized rubber or the like instead of unvulcanized rubber and having ribs 5a, 5a on both sides in the longitudinal direction is sandwiched between the joining flanges (for example, between 1a, 2a). Furthermore, it is sufficient to attach the closed-cell soft foam plate 6 not over the entire length of the joint flange, but only over a very short length, and as described above, it is sufficient to attach the closed-cell soft foam plate 6 to the unit panels 1, 2 to 4 of the bolt holes. 1 from the end
It is preferable to perform construction by applying the material to the first hole or the second hole and interposing it between the joining flanges, and the present invention is thus able to take advantage of the features of both members to a high degree. However, when the ribbed elastic material 5 of the present invention is combined with unvulcanized rubber instead of the soft foam board 6, tightening of the bolts causes shape deformation of the unvulcanized rubber instead of volume change. The ribs 5a of the elastic material 5 are pushed outside by the deformation pressure, and a sufficient water-stopping effect is not achieved.

FIGS. 7 and 8 are cross-sectional views during construction of the present invention similar to FIG. 2, and the reference numerals are the same.

〔Effect of the invention〕

As explained above, according to the water stop method of the present invention, three or more butting points of each unit panel of a panel aquarium that is assembled by joining the joining flanges formed on the periphery of the unit panel with bolts and nuts. This is a waterproof construction method in which an elastic material having ribs on both sides in the longitudinal direction is sandwiched between the flanges over almost the entire length of the joint between the joint flanges, and an elastic material is placed along the joint flange at the butt part of the panels. A short closed-cell soft foam board that fits between the ribs on both sides of the material was sandwiched between the joint flanges, and the joint flanges were tightened with bolts and nuts, so that the corners of the unit panels butted, i.e. Even if misalignment occurs in each unit panel at the cross section or T-shaped section due to variations in manufacturing or construction, lack of assembly precision, etc., the presence of the soft foam plate material can absorb the misalignment, and it can be tightened with a small tightening force. High surface pressure can be obtained. Especially near the intersection of crosses and T-shaped parts,
Since it is difficult for bolts and nuts to have sufficient tightening force, it is effective to obtain a high surface pressure with a small tightening force in order to increase the water-stopping effect. In particular, a water-stopping effect can be achieved by attaching a closed-cell soft foam board to an elastic material with a length sufficient to cover the first or second hole of the bolt hole provided in the joint flange from the butt point. This is an outstanding improvement. In this way, if a high surface pressure can be obtained with a small clamping force, it is possible to prevent the joining flange from deforming due to increasing the clamping force. Even if the soft foam board installed at the end of the joining flange hardens over time, the presence of the elastic material prevents the surface pressure from decreasing. Furthermore, since the elastic material has ribs, a high surface pressure can be obtained with a small tightening force, increasing the water-stopping effect.

Furthermore, since the members used for water-stopping are ribbed elastic materials and short plates, they are easy to manufacture and do not require the troublesome effort of assembling both members. Water can be stopped reliably at low cost.
