Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method of constructing a heat storage tank, etc., and more specifically, mainly relates to a method of constructing a heat storage tank, other water tanks, pools, etc.

(Prior art) Conventionally, as a construction method for this type of heat storage tank, for example, as in the technology described in Japanese Patent Application Laid-open No. 58-90093, a plurality of heat insulating materials are attached inside an outer wall layer made of concrete. , and there is a construction method in which the joint parts of each of the heat insulating materials are joined with a joint member such as a nail.

(Problems to be Solved by the Invention) (a) However, in the conventional construction method as described above, the joints of each insulation material are joined using joint members such as nails, so the gap between the insulation materials at the joint is The gap cannot be completely sealed off, and as a result, moisture, etc. flows in through the gap and penetrates between the insulation material and the outer wall layer, causing internal condensation and corrosion in the heat storage tank, causing damage to the heat storage tank. There was a problem that the function of the device was deteriorated.

(b) Furthermore, since the above-mentioned joint members are used, the work of joining the insulation materials becomes extremely complicated, and as a result, there is a problem that the overall construction work also becomes complicated.

The present invention was made in order to solve these problems, and it prevents the occurrence of internal condensation and corrosion as described above, maintains the function as a heat storage tank such as heat insulation effect, and also prevents the occurrence of internal condensation and corrosion. The purpose is to make the joining work easier.

(Means for Solving the Problems) The present invention has been made to solve the above problems in order to achieve such an object, and the means for solving the problems are as follows:
A plurality of heat insulating materials 2, . A plurality of bonding materials 4, separate from the waterproof sheet 3, are welded to the inside of the waterproof sheet 3 to cover the edges of each of the waterproof sheets 3, or
The method is to extend the end edge of the heat insulating material 2 from the end edge of the heat insulating material 2 in advance to form an extended portion 5, and to construct the extended portion 5 by welding it to the waterproof sheet 3 inside the adjacent heat insulating material 2. .

(Function) That is, in order to cover the edges of each heat insulating material 2, a separate bonding material 4 as described above is welded to the inside of the waterproof sheet, or the extension portion 5 of the waterproof sheet 3 as described above is adjacent to the inner side of the waterproof sheet. Since the insulation material 2 is welded to the waterproof sheet 3 on the inner side of the insulation material 2, the gaps between the plurality of insulation materials are almost completely blocked by these welds. Moisture or the like will not penetrate into the gaps between them, and therefore no condensation will occur inside the heat storage tank or the like.

(Example) Examples of the present invention will be described below with reference to the drawings.

First, as shown in Fig. 1, a plurality of waterproof sheets 3 made of polyvinyl chloride resin are pasted on the inside of a fixed-sized heat insulating material 2 made of urethane foam, and the waterproof sheets 3 are pasted. A plurality of heat insulating materials 2, . . . are installed inside the outer wall layer 1 made of concrete as shown in FIG. 2 so that the heat insulating materials 2, . . . are adjacent to each other.

As a result of this work, a heat insulating layer consisting of a plurality of heat insulating materials 2, . . . is formed inside the outer wall layer 1 as shown in Fig. 3, a waterproof layer will be formed.

Next, a bonding material 4 made of the same polyvinyl chloride resin as the waterproof sheet 3 is heated inside the waterproof sheet 3 to cover the edges of the plurality of heat insulating materials 2, . . . as shown in FIG. Weld by.

As a result, the heat insulating materials 2, . . . are interconnected, and construction of the heat storage tank is completed.

In this case, since the waterproof sheet 3 provided inside the heat insulating material 2 and the bonding material 4 are both made of the same material made of polyvinyl chloride resin, the bonding material 4 may melt due to heat. At this time, it will be integrated with the waterproof sheet 3 by welding.

Therefore, the bonding material 4 made of the same material is the heat insulating material 2.
Since they are thermally welded to the waterproof sheet 3 at the joints, the gaps between the heat insulating materials 2, . Then,
Moisture or the like does not inadvertently infiltrate from the joints between the heat insulating materials 2, . . . , and the occurrence of internal condensation and corrosion in the heat storage tank, which conventionally occurred, can be prevented.

Furthermore, since the waterproof sheet 3 is attached to the heat insulating material 2 in advance, a heat insulating layer and a waterproof layer are formed at the same time by installing the heat insulating material 2 on the outer wall layer 1, and also between each heat insulating material 2. can be very easily joined by thermal welding using the joining material 4 as described above, so that the construction work of the heat storage tank as a whole has become significantly easier than in the past.

Incidentally, the material of the heat insulating material 2 is not limited to the foamed urethane of the above embodiment, and may be, for example, foamed polyethylene, etc., and the material is not limited. The key is to use a material that has heat insulation properties.

Further, the material of the waterproof sheet 3 is not limited to the polyvinyl chloride resin of the embodiment, but may be made of synthetic rubber, for example, as long as it is waterproof.

Furthermore, the material of the bonding material 4 is not limited to the polyvinyl chloride resin of the embodiment.

Furthermore, the material of the outer wall layer 1 is not limited to the concrete of the embodiment.

In addition, in the above embodiment, the waterproof sheet 3 and the bonding material 4
Since they are made of the same material, thermal welding of the bonding material 4 has the favorable effect of reliably welding and integrating the bonding material 4 with the waterproof sheet 3. However, it is not necessary that the two be made of the same material. There isn't.

Furthermore, the means for welding the bonding material 4 to the inside of the waterproof sheet 3 at the joints of the heat insulating materials 2, . Furthermore, other welding means may be used. In short, the bonding material 4 may be integrated with the inner surface of the heat insulating material 2, more specifically, with the waterproof sheet 3, by welding. No matter what welding method is used for welding, a part of the bonding material 4 melts and is welded and integrated with the waterproof sheet 3, so in any case, the gap at the joint of the insulation material 2 is almost completely blocked. It will be done.

Furthermore, in the above embodiment, by welding the separate bonding material 4 to the waterproof sheet 3, the heat insulating material 2,...
...The joining material 4 is connected between the parts, but is not necessarily a separate joining material 4.
For example, as shown in FIG. 5, the two side edges of the waterproof sheet 3 are extended from the edge of the heat insulating material 2 in advance to form an extension 5, and the extension The insulation materials 2 may be connected to each other by welding the insulation materials 5 to the waterproof sheet 3 inside the adjacent insulation materials 2.

Furthermore, in the above embodiment, the heat insulating material 2 is provided on the outer wall layer 1 by simple installation, but the means for providing the heat insulating material 2 on the outer wall layer 1 is not limited to this, for example, by pasting, etc. It may be provided by.

Furthermore, in this embodiment, the waterproof sheet 3 is replaced by the heat insulating material 2.
Although it is provided on the inner surface side by adhesion, it is not limited to adhesion, and may be provided by other means.

In the above embodiment, the entire heat storage tank is constructed by the above-described method of attaching the heat insulating material 2 to the outer wall layer 1 and welding the bonding material 4 to the waterproof sheet. It is not necessary to use this construction method; for example, only the ceiling of the heat storage tank may be constructed using the above construction method, and the parts other than the ceiling may be constructed using other construction methods. In this case, other construction methods include, for example, the patent application filed by the applicant in 1982.
-59656 method, that is, forming a heat insulating layer on the inside of the outer wall layer with a spray-on heat insulating material, then forming a base layer on the inside of the heat insulating layer with an inorganic coating material,
After that, there is a construction method that forms a waterproof layer inside the base layer.

In addition, although the above embodiment describes the construction method of a heat storage tank, it is of course possible to apply the present invention to an aquarium or a swimming pool in addition to a heat storage tank.

(Effects of the Invention) (a) As described above, the present invention provides for welding a bonding material separate from the waterproof sheet to the inside of the waterproof sheet to cover the edges of a plurality of heat insulating materials, or This construction method connects the insulation materials by welding the extended portion of the waterproof sheet to the inside waterproof sheet of the adjacent insulation material. As a result, the gap between the joints of the insulation materials is blocked, and as in the past, the gap between the joints of the insulation materials is connected to the inside of the heat storage tank, more specifically between the outer wall and the insulation material. It has achieved the remarkable effect of preventing moisture from penetrating and preventing internal condensation in heat storage tanks and the like.

(b) Also, because the connection between the insulation materials is done by welding between the joining material and the waterproof sheet or between the waterproof sheets, without using conventional joint members such as nails, The work becomes much easier than before.

(c) Furthermore, since the waterproof sheet is already provided on the inner surface of the heat insulating material, by providing the heat insulating material inside the outer wall layer, the heat insulating layer and the waterproof layer are formed at the same time. Construction is easier than.

(d) The above (b) and (c) have the advantage that the overall construction work is significantly easier than before.
