DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art In order to enhance the cooling effect, a heat insulating plate is attached to the entire outer surface of a cooling tank, a cooling pipe or the like. As the material of the heat insulating plate, a foamed resin obtained by foaming a polystyrene, polyvinyl chloride, polyurethane or the like is usually used. Although this foamed resin is light and easy to handle, it has a property that it has low resistance to bending and easily cracks.

Therefore, conventionally, when attaching an insulating plate to an object to be insulated, such as a cooling tank having a curved surface on which the insulating plate is attached, a bendable large-sized insulating plate is used. It is cut into small pieces according to the surface shape of the cooling tank, and the cut heat insulating plates are arranged adjacent to the cooling tank while adhering to the cooling tank. In addition, when the heat insulating plate is stuck on the entire outer surface of the cooling tank, the heat insulating plate is stuck on the outside of the stuck heat insulating plate so as to further double or triple the heat insulating plate in order to improve the heat insulating performance.

However, in the case of an object to be insulated, such as a cooling tank, having an extremely large area to which the heat insulating plate is to be attached, it is difficult to apply the heat insulating plate in a double or triple manner. However, there is a disadvantage that cutting waste is generated since the large heat insulating plate is used while being cut.

[0005] Further, when there is unevenness on the tank surface to which the heat insulating plate is attached, such as a tank, the adhesion between the heat insulating plate and the tank surface is deteriorated and a gap is easily formed between adjacent heat insulating plates. There is a disadvantage that heat insulation performance is deteriorated. The present invention has been made in view of such circumstances, and proposes a heat insulating plate structure capable of easily and quickly laying a heat insulating plate on an object to be thermally insulated, and improving a heat insulating performance, and a method of attaching the heat insulating plate. The purpose is to do.

In order to achieve the above object, the present invention provides a heat insulating plate structure for laying a heat insulating plate on a surface of an object to be insulated to insulate the object. At least one formed according to the surface shape of the object to be thermally insulated
It is characterized in that a soft heat insulating plate is integrally laminated inside the hard heat insulating plate of the layer.

Further, the present invention has been made in order to achieve the above object.
In the method of attaching a heat insulating plate to the surface of the heat insulating object, in advance, a soft heat insulating plate is integrally laminated inside at least one layer of the hard heat insulating plate in accordance with the surface shape of the heat insulating object, When a heat insulating plate unit having a step portion formed at an end thereof is manufactured, and the manufactured heat insulating plates are arranged adjacently up and down and left and right and attached to the object to be insulated, a step portion of the adjacent one heat insulating plate is formed. The step formed on the other heat insulating plate is fitted into a groove formed by the surface of the object to be thermally insulated.

According to the present invention, the heat insulating plate is formed by integrally laminating the soft heat insulating plate inside the hard heat insulating plate. Absorb. Furthermore, for example, when attaching a heat insulating plate to a cylindrical heat insulating object, even if there is an error between the curvature of the heat insulating object and the curvature of the hard heat insulating plate, the soft heat insulating plate absorbs the error. Therefore,

The hard heat insulating plate 12 and the soft heat insulating plate 14
The thickness of each of them, or the ratio of the thickness of both 12 and 14, is not particularly limited, but the heat insulating performance of the heat insulating plate 10 of the present invention is ensured without using a double or triple heat insulating plate as in the conventional case. Preferably, the thickness is as large as possible. When manufacturing the heat insulating plate 10, first, the hard heat insulating plate 12 is formed according to the peripheral surface shape of the cooling tank 16.
It can be easily manufactured by displacing the flexible heat insulating plate 14 with high flexibility and bonding it with an adhesive so that the stepped portion 18 is formed.

Next, a method for attaching the heat insulating plate 10 configured as described above to the cooling tank 16 will be described. First, in a manufacturing plant or the like, a required number of heat insulating plates 10 having a required shape and size are manufactured as a required number of unit parts based on the shape, size, and the like of the cooling tank 16 to which the heat insulating plates 10 are attached, by a simulation system such as a computer. Keep it. For example, the cylindrical cooling tank 16 shown in FIG.
In this case, the peripheral surface 16A is subdivided into quadrangular shapes having the same size, and the size, the degree of curvature, and the like of the heat insulating plate 10 as a unit component for the tank peripheral surface are determined. Usually, a cylindrical cooling tank 10 having a height of about 10 m and a diameter of about 5 m
In this case, the size of the heat insulating plate 10 is usually 0.9
A tatami mat of about mx 1.8 m in width is used, and the overhang dimension L of the step is about 5 cm. Similarly, the heat insulating plate 10 obtained by subdividing the top plate 16B of the cooling tank 16 is manufactured as a unit component for the tank top plate.

When attaching the heat insulating plate 10 to the peripheral surface 16 A of the cooling tank 16, first, as shown in FIGS.
0 (A) is fixed with an adhesive or the like. Next, a vertical groove 20A (a groove formed at the left end or the right end of the heat insulating plate 10) formed between the stepped portion 18 of the heat insulating plate 10 (A) and the surface of the cooling tank 16 is fixed. The step 18 of the next heat insulating plate 10 (B) is fitted, and the heat insulating plates 10A and 10B are connected to each other with the adhesive tape 22. Thereby, the adjacent heat insulating plate 1
The 0 step portions 18 are connected in an overlapping state.
Similarly, the heat insulating plates 10 (C), (D), and (E) are sequentially fitted and connected with the adhesive tape 22, and the cooling tank 1
6, a first-stage heat-insulating plate continuous body in which the heat-insulating plates 10 are annularly connected to each other is formed. The outer periphery of the continuous heat insulating plate is banded with a band 24 and fixed.

Subsequently, a groove 2 formed at the upper end portion of the heat insulating plate continuum between the first-stage heat insulating plate continuum and the surface of the cooling tank 16.
0B, the lower step portion 18 on the lower side of the first heat insulating plate 10F of the second step.
Fit. Next, a vertical groove 20A formed by the first heat insulating plate 10 (F) of the second stage and the surface of the cooling tank 16 is formed.
The step 18 of the heat insulating plate 10 (G) is fitted into the (groove formed at the left or right end of the heat insulating plate 10), and the second step is formed in the same manner as when the first-stage heat insulating plate continuous body is formed. And then banding. In FIG. 5, the groove 20B is formed at the upper end of the heat insulating plate 10. However, when the groove 20B is formed at the lower end of the heat insulating plate 10 as shown in FIG. 6, rainwater hardly collects in the groove 20B.

Then, the work of attaching the heat insulating plate 10 to the upper part of the cooling tank 16 is performed, so that the heat insulating plate 10 is attached to the entire peripheral surface 16A of the cooling tank 16. After the heat insulating plate 10 is attached to the entire peripheral surface 16A of the cooling tank 16, a thin iron plate 24 is wound around the heat insulating plate 10 to protect and fix the heat insulating plate 10 as shown in FIG.

For this reason, it is not necessary to cut the large-sized heat insulating plate into a required size according to the surface shape of the cooling tank 16 as in the conventional case, and the heat insulating plate is attached to the cooling tank 16 one by one with an adhesive. You don't have to. Accordingly, no cutting waste is generated by cutting, so that not only the loss of the heat insulating plate material can be reduced, but also the on-site environment can be improved.

In addition, by overlapping the step portions 10 of the heat insulating plates 10, no gap is generated between adjacent portions of the heat insulating plates 10, so that the heat insulating performance is improved. In this case, the heat insulating performance is further improved by arranging the heat insulating plates 10 attached to the cooling tank 16 such that the positions of the left and right ends of the heat insulating plates 10 coincide with every other step as shown in FIG. be able to.
