グルデッキ式である。2. Description of the Related Art Generally, in a storage tank of heavy oil, crude oil, or the like having a high viscosity at room temperature, the oil storage temperature is maintained at 50 to 60 ° C. in order to ensure fluidity of the oil storage. Therefore, it is necessary to install a heat insulating material in the tank from the viewpoint of energy saving. However, tanks for storing heavy oil, crude oil, etc. are often of the floating roof type, and most of them are of the single deck type.

多くある。FIG. 2 schematically shows the structure of a storage tank having a single-deck floating roof. In the figure, T is a tank, B is a circular floating roof, 1 is a steel deck plate constituting the floating roof, 2 is a pontoon, and 3 is a seal member. Since the deck plate of the single deck type floating roof is made of a steel plate with a thickness of about 4.5 mm, it can be easily wavy deformed by wind pressure or walking of inspection workers. Insulation is difficult to apply, and the deck plates of existing single-deck tanks often have no insulation.

Since the temperature inside the tank is 50 to 60 ° C., the heat insulating material does not deform at this temperature, and there is no occurrence of peeling or cracking. Excellent weather resistance. Since it is often exposed to rainwater, it has a structure that does not absorb water. It has the flexibility to always follow the deformation of the deck material. Does not promote deck material corrosion. Passes the fire resistance standard of the Fire Service Law.

In the figure, reference numeral 1 denotes a deck plate, on which a heat insulating material 4 having fire resistance and flexibility is attached to an adhesive 5 having flexibility even after curing.
When the waterproof sheet member 6 is provided on the surface of the heat insulating material 4 to form a heat insulating structure, the deck plate 1 is deformed by wind pressure or the like until the adhesive is cured, and the waterproof heat insulating material 4 is Since it is highly possible that the adhesive 7 is peeled off, it is necessary to place the weight 7 on the waterproof heat insulating material until the adhesive is cured.

くない。However, when a rigid material such as a concrete block is used as the weight, when the deck plate is deformed due to wind pressure or the like, the weight cannot follow the wavy deformation of the deck plate, as shown in FIG. In addition, the waterproof insulation may peel off from the deck plate. In order to prevent this, it is sufficient to prepare a weight having a sufficient weight so that the deck plate is not deformed by wind pressure or the like. However, the thickness of the deck plate is as thin as about 4.5 mm, and a waterproof insulation material is used. In view of the mechanical strength of the above, it is not preferable to use a heavy weight.

材が剥離することはなかった。While the adhesive was being cured, the deck plate was deformed due to wind pressure and the walking of the inspection worker. However, as shown in FIG. 1B, the ability of the weight 8 to follow the deformation of the deck plate was reduced. Because of the good condition, the waterproof heat insulating material did not peel off from the deck plate during the curing of the adhesive. Also, even if the weight is removed after curing of the adhesive, the adhesive has flexibility even after curing, and the waterproof insulation material also has flexibility,
The deformation of the deck plate could be followed, and the waterproof insulation did not peel off.
