この発明は冷暖房用の蓄熱槽の断熱構造に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating structure for a heat storage tank for heating and cooling.
この種の蓄熱槽は、その蓄熱媒体としては一般的に水が
使用されており、何等かの断熱(保温、保冷)施工が必
要であって、そのために断熱材が用いられる。This type of heat storage tank generally uses water as its heat storage medium, and requires some kind of insulation (heat retention, cold retention) construction, and a heat insulating material is used for this purpose.
通常使用される断熱材の熱伝導率は0.0狐oaそ/m
h。0前後であるが、吸水すれば水の性状に近づくため
著しく断熱性能が低下する。The thermal conductivity of commonly used insulation materials is 0.0 oaso/m
h. However, if it absorbs water, its properties will approach those of water, and its insulation performance will drop significantly.
例えば、水の熱伝導率は0.5狐caゼノmh。0であ
るから、吸水状態での断熱材の断熱性能は1′10以下
に低下することになる。For example, the thermal conductivity of water is 0.5 fox ca xeno mh. 0, the heat insulating performance of the heat insulating material in the water absorption state will drop to 1'10 or less.

は、断熱材に対し何等かの防水(湿)対策を施さなけれ
ばならない。In addition, some of the insulation materials most commonly used today, such as styrofoam, glass wool, and urethane foam, have a closed-cell structure due to their formation process and are relatively difficult to absorb water (for example, stylofoam). However, if they are immersed in water for a long period of time, they will absorb water. Moreover, once water has been absorbed, it is difficult to release water. Therefore, when using insulation material inside the fly body wall of a heat storage tank (insulation construction is usually done inside the tank)
, some kind of waterproof (moisture) measures must be taken for the insulation material.

In other words, the reason why a heat insulating material has high heat insulating properties is due to the finely divided air layers (which may also be bubbles) contained therein, and air convection is prevented due to the finely divided air layers. It is said to be for the purpose of For this reason, the insulation material also contains a large amount of air and is relatively light for its volume, so naturally it receives much more buoyancy than its own weight in water, and in heat storage tanks, the buoyancy causes it to fall off the walls or bottom. Preventive measures are required. In view of the above points,
The insulation structure applied to the lateral inside is a waterproof layer (
A structure is adopted in which a heat insulating layer (asphalt, etc.), a waterproof layer, and a supporting and reinforcing layer (mortar, lath with reinforcing steel, perlite mortar, 9/2 skin steel plate, etc.) are sequentially formed.

である。However, such a structure not only requires a large number of steps and is time-consuming, but also requires all construction on-site, resulting in high manufacturing costs. In addition, if the support layer is not reinforced,
It is incomplete to prevent buckling due to the buoyant force acting on the insulation material (a force that causes the insulation material to warp back toward the water side, causing it to fall off). Rust between the slabs becomes a problem. As shown in FIG. 1, a heat insulating material 2 is applied to the inner surface of the hatchling crab 1, and after this is fixed to the key body wall 1 with a bolt-shaped fixing member 3, a waterproof sheet 4 is applied to the surface and the bottom of the turret. There is a heat storage tank that is attached to the heat storage tank itself and the heat insulating material to make it waterproof, but in this case, no waterproofing means is provided between the fly wall (concrete) 1 and the heat insulating material 2. Therefore, the heat insulating material 2 may absorb water due to water vapor emanating from the nest wall 1 for a long period of time. In order to avoid this even to the slightest extent, it is necessary to allow a considerable dry period after pouring concrete, which increases the construction period. This invention was made in view of the above points, and its purpose is to prevent water absorption in the insulation material for a long period of time with a simple structure, prevent it from falling off from the side wall, and achieve a relatively short construction period. The present invention provides a heat insulating structure for a heat storage tank that can be easily manufactured.

にある。The feature of the present invention for the above-mentioned purpose is that the inner surface of the hatch wall of the heat storage tank is mirror-slanted inward toward the top, and a flat insulating material that receives a buoyancy force greater than its own weight is placed on the inner surface of the key wall. A large number of block-shaped unit heat insulators are formed and provided with moisture-proofing means, and a large number of unit insulators are arranged in a row, and a fixing member to the nest wall is provided at the joint of each unit insulator.
この発明を第2図以下に示す実施例により詳説する。This invention will be explained in detail with reference to embodiments shown in FIG. 2 and below.

が防止される。A unit heat insulating material (hereinafter simply referred to as a heat insulating material) formed into a block shape and wrapped in a moisture-proof sheet (such as a polyethylene sheet) 13, and 14 are stud-like fixing members to prevent peeling. The inner surface of the fly body wall 11 is inclined inward toward the top, and the opening at the top end, which is closed by the top slab 15, is smaller than the bottom dimension. The square heat insulating material 12 formed in a block shape is aligned and attached to the inner surface of the fly body crab 11 whose forehead is inclined inward, and the key body wall is fixed by the fixing member 14 so as not to damage the moisture proof sheet 13. It is fixed at 11. That is, each heat insulating material 12 is fixed at each joint (in the drawings, at each corner). The fixing member 14 is attached to the sea bream wall 11 by driving or screwing, and its flat head prevents the heat insulating material 12 from falling off. The peeling prevention force of the fixing member 14 may be sufficient to prevent the insulation material 12 from peeling off due to its own weight during drying during cleaning or construction process, and when it is full of water, a pressure component against the side wall due to buoyancy is added to ensure a reliable This prevents peeling.
このような浮力の側壁部への押圧成分が剥落防止力とし
て作用することは、第4図より明らかである。It is clear from FIG. 4 that the component of the buoyant force that presses against the side wall portion acts as a peeling prevention force.

=Vsinaとなる。That is, when the hatchling body wall 11 is inclined inward by the forehead oblique angle 0 and a buoyancy force F acts on the heat insulating material 12 on the inner surface of the fly body wall, the buoyancy force F is equal to the upward force component Q acting upward along the wall surface, and the wall surface. can be divided into a pressure component P that presses the pressure component P: Fs
It is expressed as in8. The above buoyant force F is expressed as F=V if the volume of the heat insulating material 12 is V, so the pressure component P is P
=Vsina.

にもなる。For example, if a styrofoam with a thickness of 10 mm and 1 square inch is used as a heat insulating material, and the oblique angle of the forehead is 10 degrees, the pressure component P of each heat insulating material 12 on the wall surface of the sea bream body is P = 10 (2) x 100. (inhibition)

ものとなる。This pressing component P provides a stable peeling prevention force at all times (when the water is full). Note that the upward force component Q is received by the upper slab 15 as a cumulative force from the bottom to the top. On the other hand, when the water is full, the insulating material 12 is constantly under pressure against the frame wall 11, so the flow resistance of the permeated water between the moisture-proof sheet 13 on the back of the insulating material 12 and the gutter wall is large, and the permeated water The heat transfer loss (convection heat loss) associated with the flow of is so small that it can be ignored.

ことができ、良好な断熱性が維持される。Note that the heat insulating material 12 may be primarily fixed to the inner surface of the frame wall using an adhesive. As described above, according to the present invention, the inner surface of the frame wall of the heat storage tank is formed to be inclined inward toward the top, and the unit heat insulating material formed in a block shape and wrapped with a moisture-proof sheet is arranged on the inner surface. Since it is attached to the wall and fixed with a fixing member, the component of buoyancy that presses against the inner surface of the building wall can be used as a force to prevent peeling, making it possible to stably maintain the unit insulation material and preventing water absorption over a long period of time. can maintain good thermal insulation properties.

効果をも有する。In addition, the process of converting the unit heat insulating material into a flock and packaging it with a moisture-proof sheet can be done in a factory, which has the advantage of not only being able to manufacture the unit in a short period of time and at low cost, but also making it easy to install.
