Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reinforcing structure for a panel aquarium.

A panel aquarium is made by dividing into a large number of unit boards (panels), which are then assembled on site. The panel used here has flanges bent in the same direction on the four sides of a rectangle, and these flanges are abutted against each other and assembled in sequence to form a box-shaped aquarium. The side walls of the panel water tank assembled in this manner were deformed by hydrostatic pressure and fluctuating water pressure during an earthquake, and there was a risk of destruction. Therefore, attempts have been made to improve earthquake resistance, durability, etc. by installing a large number of reinforcing agents such as tension rods and diagonal stays between the side walls and between the side walls and the bottom wall within the water tank. However, since the reinforcing material that is bridged within the tank is a metal rod-shaped member, there were problems in terms of rust and hygiene. Even when stainless steel is used as a reinforcing material, rust is observed in aquariums that store drinking water due to sodium hypochlorite, which is used to sterilize tap water, and aquariums that store seawater. However, even stainless steel is severely corroded and has a lifespan of only about one year. Further, if the reinforcing material is made of metal, heat transfer is good, so it is not suitable for a heat insulating water tank, and dew condensation is likely to occur at the attachment portions of each wall of the water tank and the reinforcing material. Furthermore, in aquariums assembled with FRP panels, the main body of the aquarium (FRP)
The reinforcing material (metal) and the reinforcing material (metal) have extremely different strength characteristics and elastic modulus due to the difference in materials, which makes it extremely difficult to design the mounting part and also difficult to install. Furthermore, in order to provide sufficient seismic performance, a considerable number of reinforcing materials must be placed around the premises, which results in poor work efficiency and makes maintenance management such as periodic cleaning of the inside of the tank extremely difficult. It was hot.

The present invention was invented in view of the above circumstances, and it prevents the occurrence of rust, is highly safe in terms of hygiene, is suitable as an insulating water tank, and is not only easy to install but also easy to maintain. It is an object of the present invention to provide a reinforced structure for a panel aquarium that is easy to carry out and has excellent earthquake resistance and durability.

Some preferred embodiments of the present invention will be described below with reference to the drawings.

In the first embodiment shown in FIGS. 1 to 7, a panel aquarium 1 is assembled from a plurality of panels 2, and the flanges 2a of each panel 2 are abutted and joined together. The panel 2 used here is usually 1m x 1
m size is used, but so-called half size 1m x 0.5m size is also used,
As for the material, one made of FRP is suitable. A lightweight structure 7 having a skeleton made of reinforced plastic 6 is installed between the corner part formed by the adjacent side walls 3, 3 in this panel aquarium 1, along the ceiling 4, and between the ceiling 4 and the bottom wall 5. be. As shown in FIG. 2, this lightweight structure 7 has a hollow quadrangular column shape and is constructed in a truss structure. The skeleton of the reinforced plastic 6 is constructed from a plurality of rods, and the basic rod is prepared with a plurality of joints 8 as shown in Fig. 3a and b, and as shown in Fig. 4a. , b, a continuous fibrous (string-like) piece of uncured reinforced plastic 6 is wound between joints 8, 8 a plurality of times. By arranging four such rods at predetermined positions, and wrapping or adhering uncured reinforced plastic 6 around these rods (bonding as it hardens),
A hollow quadrangular prism-shaped structure 7 as shown in FIG. 2 can be constructed. Alternatively, as shown in FIG. 5, it is also possible to construct a truss structure structure 7 using two joints 8, 8 on one end side. A hole 8a is bored in the joint 8, and the joint 8 is connected to a fixture 9 that is attached to the side wall 3, the ceiling 4, or the bottom wall 5 using this hole 8a. The relationship between the fixture 9 and the joint 8 will be described later. Reinforced plastic 6 forming the skeleton of the lightweight structure 7
For example, by impregnating a bundle of glass fibers (called roving, which has never been twisted) with unsaturated polyester, when the unsaturated polyester is in an uncured state, a three-dimensional structure as shown in Figure 2 is constructed. An integrated lightweight structure 7 is obtained by curing the unsaturated polyester. The glass fibers used here are continuous high-tensile glass fibers, but in addition to glass fibers, carbon fibers and Kevlar can also be used, and epoxy resins, phenolic resins, etc. can also be used as resins. It is possible. Further, since the roving in an uncured state has various degrees of freedom in design, it is possible to manufacture the structure 7 having a shape other than a hollow square columnar truss structure. That is, it is possible to manufacture structures 7 having various one-dimensional to three-dimensional shapes and functions.

As an example of attaching the joint 8 and the fixing device 9, as shown in FIGS. 6 and 7, the base plate 91 of the channel-shaped fixing device 9 is attached to the location where the four panels 2 constituting the side wall 3 are butted together. and then install the joint 8 between the vertical plates 92, 92 of the fixture 9. Four holes 91a are drilled in the board 91, and the bolts 11 are inserted into the holes 91a and the four holes of the fixture 10, which are inserted between the holes 91a and the places where the flanges 2a form a cross. It has been concluded. A spacer 13 is fitted onto the bolt 11. The joint 8 is attached by aligning the holes 92a, 92a of the vertical plates 92, 92 with the hole 8a of the joint 8, inserting bolts 11 into these holes, and fastening them with nuts 12. Note that the fixture 9 itself and the reinforced plastic 6 may be integrated from the beginning. In this case, the fixture 9 also serves as the joint 8. Further, the shapes of the fixture 9 and the joint 8 are not limited to those shown in the drawings, and various shapes and structures can be adopted.

8 to 10 show a second embodiment of the present invention, in which a hollow right triangular prism-shaped lightweight structure 7 is provided at each corner formed by adjacent side walls 3, 3 in a panel aquarium 1. It is installed. In this embodiment, the joint 8 also serves as a fixture 9, and the hole 8a of the joint 8 is used to attach a lightweight structure to each wall (3 to 5, in some cases, it may not be necessary to attach it to the wall of the ceiling 4). 7 is installed.

11 to 13 show a third embodiment of the present invention, in which the space between the opposing walls (side walls 3, 3) in the panel aquarium 1 is shown.
A lightweight structure 7 formed not three-dimensionally but in a flat plate shape is attached between the ceiling 4 and the bottom wall 5. This flat plate-shaped lightweight structure 7 may have a truss structure as shown in FIG. 12 or a ladder-like structure as shown in FIG. 13.

FIGS. 14 and 15 a and b show the fourth embodiment of the present invention.
In this embodiment, a flat plate-like lightweight structure 7 shown in FIGS. 12 and 13 is vertically installed along the abutting points of the panels 2 of the four side walls 3. In addition to this embodiment, a flat plate-like lightweight structure 7 is added along the butting points of the panels 2 of the ceiling 4 and the bottom wall 5.
It is of course possible to additionally install the
(See Figure 6). Furthermore, these flat lightweight structures 7
It is also possible to install a three-dimensional lightweight structure 7 having a predetermined depth along the wall surface inside the panel aquarium.

FIG. 17 shows a fifth embodiment of the present invention, in which a flat lightweight structure 7 is installed obliquely between adjacent walls of a panel aquarium 1, that is, between a side wall 3 and a bottom wall 5. .

FIG. 18 shows an example of how three-dimensional lightweight structures 7 are connected to each other. In this structure, hollow quadrangular prism-shaped lightweight structures 7 are made separately and connected using joints and bolts and nuts.

FIG. 19 shows a structure made by intersecting the flat lightweight structures 7, which can also be installed inside the panel aquarium 1 as shown in FIG. 20.

In the various embodiments described above, the lightweight structure 7 has a flat plate shape or a three-dimensional shape, but as mentioned earlier, this lightweight structure 7 has various shapes and functions from one dimension to three dimensions. The present invention is not limited to the shape and structure of the light-weight structure 7 shown in the drawings, since it is possible to manufacture a structure having a similar structure. Therefore, it is of course possible to use a rod-shaped lightweight structure 7.
Furthermore, it goes without saying that the manner in which the lightweight structure 7 is attached within the panel aquarium 1 is not limited to the illustrated embodiment. That is, the lightweight structure 7
may be arranged along the wall in the panel aquarium 1, may be arranged astride between opposing walls, or may be further arranged astride between adjacent walls. Furthermore, any two or more of these attachment modes may be combined.

As explained above, the present invention provides continuous high tensile strength that can be applied along the walls of a rectangular aquarium constructed by assembling panels, or between opposing walls, or between adjacent walls, or a combination of two or more of the above. It is characterized by the attachment of a lightweight structure whose skeleton is made of reinforced plastic made of a combination of fibers and unsaturated polyester. Therefore, rust is prevented from forming inside the panel water tank, which is sanitary, and the insulation performance is also improved compared to metal reinforcement.
Furthermore, when a flat or three-dimensional lightweight structure is used, installation work and maintenance management become easier. Furthermore, according to the present invention, reinforcement with excellent earthquake resistance and durability can be easily performed.

A lightweight structure constructed into a truss structure has better strength. In addition, in cases where the reinforced plastic that forms the skeleton of a lightweight structure is formed by wrapping it in a continuous uncured fibrous state between various joints multiple times, for example, a combination of glass fiber and unsaturated polyester is used. When reinforced plastic is used, the weight is reduced to one-fourth to one-fifth compared to a steel structure with the same strength (equivalent stiffness), and the tensile strength is approximately 8000 kg/cm ² and the compressive strength is approximately 3500Kg/cm ² , expansion coefficient approximately 8.6×10 ^-6 /
℃, and the thermal conductivity was approximately 0.3W/m℃, which is suitable for use in reinforcing panel water tanks.
