Abstract

PURPOSE:To improve the pressure tightness, by placing insulator between partition panels which are erected face to face and which flanges are fixed to a side wall and bottom wall. CONSTITUTION:Partition panels 11, 12 are fixed to a bottom wall 15 with bolts and nuts while making pressure receiving surfaces 13 face each other and flanges 14 locate outside. Between the partition panels 11, 12, which are facing each other, an insulator 16 is placed to form a partition wall 10; the flanges 14 are fixed to the bottom wall 15 and a side wall without clearance. To the space between the pressure receiving surfaces 13, the insulator 16, which has been liquidized, is poured and foamed. The space between the upper ends of the partition panels 11, 12 and flanges 18 of a ceiling wall 17 is connected with brackets 19, which have an L-shaped cross section, using bolts and nuts, etc.; the space is eliminated to prevent the foamed insulator from being exposed through the upper ends.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to a partition wall applicable to a water tank for storing heat of hot water, and a method for forming the partition wall.

[Prior art]

In recent years, so-called heat storage tanks, which have a heat-retaining structure surrounding an assembled water tank and store hot water, have come into widespread use.

However, in order to store water with different temperatures, partition walls are formed, but there are few effective heat retention structures for these partition walls, and improvements have been sought.

FIG. 2 is a partial cross-sectional view of an assembled water tank used as a heat storage tank, and FIG. 3 is a cross-sectional view of a conventionally used unit panel 1 provided with heat retention performance. The unit panel 1 constitutes the side wall W1 and the bottom wall W2 of the prefabricated aquarium, and eight walls W1 and W2 are constructed by sequentially connecting flanges 3 erected around the pressure receiving surface 2. Although not shown, the ceiling wall is also constructed in the same manner.

As shown in Fig. 2, the unit panel l constituting each outer wall has a heat insulating material 4 such as polyurethane foam attached to the surface surrounded by the pressure receiving surface 2 and the flange 3, and an outer surface material 5 is attached to this surface. It will be done. In this case, the outer surface material 5 that forms the outside of the water tank is very thin and does not require much strength because the pressure of the stored water is directly applied to it.

However, if this unit panel 1 is applied as it is to the partition wall W3, the water pressure of the stored water will be directly applied to this outer surface material 5, and the cost for forming the outer surface material 5 will be extremely high, so it is not used. . On the other hand, it is also possible to sandwich the foam material 4 and press-form it from both sides, but this also requires a difficult technique considering the possibility of buckling of the foam material 4 due to pressure.

〔the purpose〕

The present invention takes the above facts into consideration and aims to provide a partition wall with excellent pressure resistance and a method for forming the partition wall.

〔composition〕

The first invention of the present application is characterized in that a side wall, a bottom wall, and a flange around the side walls and a flange around the sides are fixed, and a partition panel body is erected facing each other, and a heat insulating material is interposed between the partition panel bodies. There is.

The second invention of the present application connects a side wall and a bottom wall at a right angle, fixes a flange provided around a unit panel forming a partition wall to each wall, and fixes a flange of the unit panel to each wall. The present invention is characterized in that after sequentially connecting one partition panel body to form one partition panel body and forming the other partition panel body at intervals in the same manner, a heat insulating material is inserted between these partition panel bodies.

Here, the unit panel body may be made of stainless steel or FRP, and the heat insulating material may be polyurethane foam, polystyrene foam, incyanurate foam, glass fiber, or the like. Considering the molding method, this heat insulating material is also preferably injected in liquid form between the partition panels, and in this example, rigid polyurethane foam is preferred. In short, the partition wall has a structure in which partition panels, which serve as the surface material of the wall, are opposed to each other, preferably assembled with their faces facing each other so that the flanges are opposite, and it is desirable to inject and foam a heat insulating material between them.

〔Example〕

FIG. 1 is a cross-sectional end view of an assembled water tank mainly having a partition wall according to the first invention. That is, the inner partition panels 11 and 12 are placed on the bottom wall 1 with the so-called pressure receiving surfaces 13 facing each other and the flanges 14 on the outside.
5 with bolts and nuts (not shown).

A heat insulating material 16 is interposed between the opposing partition panels 11 and 12 to form the partition wall 10.

This flange 14 is fixed to a bottom wall 15 and a side wall (not shown) without any gaps. Insulating material 16 between pressure receiving surfaces 13
is injected into a liquid and foamed. In so-called in-situ foaming, connection without gaps is particularly required.

The upper end of the partition panel 11.12 is connected to the flange 18 of the ceiling wall 17 using bolts, nuts, etc. with a cross-sectional bracket 19, with no gaps left so that the foam insulation material is exposed from the upper end. I try not to do that. The bracket 19 may be fixed after the foam is filled, or if the bracket 19 is fixed in advance, an air vent hole may be formed in the bracket 19 etc. when the foam is filled.

〔effect〕

The present invention has the above-described structure, and the partition panel has an excellent effect that not only the unit panels constituting the side walls and the bottom wall can be used as they are, but also that it is extremely easy to cope with water pressure.

Furthermore, the thickness of the partition walls can be easily adjusted by changing the spacing between the partition panels, and if the expected water temperature is known, it is now possible to easily improve the heat retention performance.
