As a thing. Then, the acrylic resin plate 3 adheres the rear side plate and the left and right side plates with an adhesive for acrylic resin at the end, and only the front side plate is the left and right side plates that are opposed to each other as the glass plate 2. It arrange | positions between the front ends of the system resin board 3 and 3. FIG. In this case, as the state the glass plate 2 which is in contact with the other party inner surface of the short eave plate 4 mentioned above the distal end outer surface is provided on both the acrylic resin plate 3, the left and right both ends surfaces of the glass plate 2 It arrange | positions so that the required clearance gap 5 may each be formed between the acrylic resin plates 3 which are side plates. Further, in the gap 5, as described above, a protruding step portion 7 is provided in a portion extending from the inner surface of the end portion of the acrylic resin plate 2 to the inner surface of the short rib plate portion 4 to improve the bonding strength. A band plate made of an acrylic resin that is the same material as the acrylic resin plate 2 and the short rib plate portion 4 is bonded with an adhesive for the acrylic resin. In addition, it is good also as what made the adhesive layer 6b intervene between the front-end | tip outer surface of the said glass plate 2, and the front inner surface of the short eaves board part 4. FIG.
[0007]
The glass plate 2 and the acrylic resin plate 3 are joined together by a silicon resin joining material 6 that fills a corner formed by both plates and interposes a part 6a thereof in the gap 5 described above. It has become. In this case, the above-described convex stepped portion 7 is not necessarily required. However, if the convex stepped portion 7 as described above is provided, the glass plate 2 and the acrylic plate 6 are partly interposed in the gap 5 described above. The silicon resin-based bonding material 6 filling the corners where the resin-based resin plate 3 is bonded becomes bowl-shaped, so that the water pressure applied from the inside of the water tank body 1 to the glass plate 2 and the acrylic resin plate 3 is increased. On the other hand, it is more preferable because it has a better pressure strength. A part 6a of the silicon resin-based bonding material 6 intervening in the gap 5 is also interposed between the front outer surface of the glass plate 2 and the front inner surface of the short rib plate portion 4 as shown in FIG. Even if the adhesive layer 6b for bonding the two is formed, as shown in FIG. 3, it is not intervened between the tip inner surface of the glass plate 2 and the front inner surface of the short rib plate portion 4. Also good.
[0008]
Since what was comprised in this way makes the subjective prize surface into the glass plate 2 among each side plate surface which comprises the water tank main body 1, and makes the remaining side plate surface into the acrylic resin board 3, From the glass plate 2, The subjective award plane will not be deformed due to moisture absorption, etc., and will be excellent in appreciation. Moreover, since the glass plate 2 is hard and hard to be damaged, it can efficiently remove dirt with a simple work. Management. Furthermore, since it was made of a lightweight acrylic resin plate 3 except for the subjective award, it is light and easy to handle as a whole, and the acrylic resin plate 3 has good hole workability, so it can be connected to peripheral equipment. In addition, the hole processing for piping is easy, and there is an advantage that it can be manufactured at a relatively low cost.
