Description

[Detailed explanation of the invention] This invention is mainly used for hot water supply and heating of residences, facilities, companies, etc.
Or side wall corner joint devices such as panel heat storage tanks for storing hot water supplied from solar water heaters or water heaters using other heat sources for the purpose of industrial use. It is related to.

Normally, the thickness of a heat insulating material filled as a core material inside a single side wall of a panel type heat storage tank etc. often has to be changed due to heat retention properties.

Along with this, a wide variety of devices of this type have been devised in the past, but in all of them, it is impossible to change the thickness of the heat insulating material with a single type of oval type. A large number of different shapes had to be prepared, and the shape of the side wall alone was not only troublesome but also uneconomical.

Therefore, this idea was devised to eliminate the above-mentioned drawbacks, and involves installing flanges at the corner side edges of a pair of single side walls that constitute the side wall corners of a panel type heat storage tank, etc. At the same time, a corner joint metal fitting having a substantially right-angled cross section and a reinforcing diagonal piece provided on the bent side is brought into contact with the corner side edge surface of each single side wall, and the corner joint metal fitting of each flange is made to protrude. By connecting the corner reinforcement plates to the opposite sides with bolts and nuts, the insulation material can be easily adjusted by simply changing the width of the flange of each side wall with a single type of guide type. To provide a highly economical side wall corner joining device for a panel type heat storage tank, etc., which allows the thickness to be freely changed and allows the side wall to be formed into a certain shape extremely easily.

An embodiment of this invention will be described below with reference to the drawings.

As shown in the figure, glass fiber reinforced plastic (hereinafter referred to as FR)
A pair of side walls 4 forming a side wall corner B of a panel type heat storage tank A, etc., in which the inner layer 1 and outer layer 2 made of P) are filled with a heat insulating material 3 made of foamed plastic such as hard urethane foam. Outward flanges 5 are provided protruding from the side edges of the corners, and several joining holes (not shown) are bored in each of the flanges 5 at appropriate intervals along the vertical direction.

On the other hand, joint holes (not shown) corresponding to the joint holes of the respective flanges 5 are formed at appropriate intervals along the vertical direction, and are connected to each joint piece 6 for abutting at right angles to each other, and on the bending part side. Corner joint fittings 8 having a substantially right-angled cross section are formed from reinforcing diagonal pieces 7 provided so as to intersect each joint piece 6 at an angle of approximately 135 degrees, and a corner joint fitting 8 is formed in the joint hole of each flange 5. A corner reinforcing plate 9 having an L-shaped cross section is formed with corresponding joining holes (not shown) formed at appropriate intervals along the vertical direction.

Then, the corner joint fittings 8 are brought into contact with the corner side edge surfaces of the respective side walls 4 arranged at right angles, and the respective joining holes of the corner joining metal fittings 8 are connected to the respective joining holes of both flanges 5. A corner reinforcing plate 9 is placed on the opposite side to which the corner joining fittings 8 of No. 5 are not in contact.
They are connected with bolts 10 and nuts 11, respectively.

Although this device is constructed as described above, only the length of the width of the flange 5 of each side wall unit 4 is changed using one type of oval type, as shown by the solid line and the dashed-dotted line in Fig. 2. Since the thickness of the heat insulator 3 can be changed freely, the side wall 4 can be shaped extremely easily without having to prepare multiple types of heat insulators 3 with different thicknesses as in the past. Not only that, but it can be provided at a low price and is extremely economical.

Furthermore, by being able to freely change the thickness of the heat insulating material 3, it is possible to increase the thermal efficiency of hot water and to significantly improve the heat storage effect of a panel type heat storage tank or the like.

Further, the provision of the diagonal piece 7 on the bent side of the corner joint fitting 8 and the interposition of the corner reinforcing plate 9 on the opposite side of the corner joint fitting 8 of each flange 5 during joining are combined. As a result, the strength of the corner joints of each side wall unit 4 can be significantly increased, so that even after long-term use, leakage of hot water from the corner joints can be reliably prevented.

Furthermore, although this invention has been explained to be used for a panel type heat storage tank, it is not limited to this in any way, and can be used for water receiving tanks,
Of course, it can also be used for aquariums such as elevated aquariums and underground aquariums.

As explained above, according to the side wall corner joining device of this invention, the thickness of the heat insulating material can be freely changed using one type of mold, making it extremely easy to shape a single side wall and extremely economical. In addition, the heat storage effect of the panel type heat storage tank and the like can be improved, and the strength of the corner joints can also be significantly increased to reliably prevent hot water from leaking.
