The present invention relates to a heat insulating envelope made of a coated stainless steel material, which can be expanded and contracted to prevent damage due to earthquakes, thermal stress, etc., and can also have suitable strength.

[Conventional technology and its problems, etc.]

BACKGROUND ART In recent years, from the viewpoint of energy saving and improving the living environment, it has become popular to provide structures with insulation and waterproofing. Among them, asphalt insulation and waterproofing methods for structures such as buildings are generally performed using only asphalt, which has high waterproofing efficiency, or in combination with various types of heat insulating materials. The asphalt deteriorates over a few years and its waterproofing and insulation performance deteriorates significantly, so it has to be re-waterproofed, resulting in huge maintenance costs. In addition, structures that require airtightness and insulation (for example, structures that require fumigated or sterile spaces, spaces that block outside air, etc.) are generally constructed of reinforced concrete.
There were drawbacks such as an extremely early decline in airtightness and heat insulation performance due to cracks, etc. Furthermore, it is desired to prevent damage from earthquakes, thermal stress, etc., but at present there is no one that is easy to construct and that can be expected to be sufficiently effective.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor has developed the present invention, which uses a coated stainless steel material in which rising side portions are formed on both sides of a long main plate in the width direction. It is placed on a single layer of insulation material having the same width as the covered stainless steel material laid on the outer surface or inner surface, and has a substantially flat plate-shaped hanger main body with a mounting hole bored at one location approximately in the center. , the lower end of a relatively high movable tongue piece is locked, and the movable tongue piece is made sufficiently slidable within the length of the length of the hanger body in the longitudinal direction to form a movable hanger, and the movable tongue piece is brought into contact with the rising part of one side of the coated stainless steel material, and the main body of the hanger is fixed to the outer surface or inner surface of the structure through the mounting through-hole with a fixing tool, and the movable Provide multiple suspenders and cover the suspenders themselves,
In addition, one layer of adjacent insulation material is laid so as to be in contact with the side edge of the previous insulation material, and the other side of the adjacent coated stainless steel material on the adjacent insulation material is laid on the rising part of the side of the one side. The rising parts of the side parts are overlapped, the movable tongue piece is sandwiched therebetween, and the rising parts of both sides are seam-welded to each other to form an expansion joint part with an open lower side,
The movable tongue piece can slide only in the longitudinal direction of the expansion joint, and the insulation envelope is made of coated stainless steel, etc., making it completely watertight and airtight, with extremely high insulation performance. It is an excellent product, does not require any maintenance, is extremely durable, is economically inexpensive, and can be expanded and contracted to withstand earthquakes, thermal stress, etc. , this damage can be prevented and the strength can be improved to solve the above problems, and the insulation material with the above-mentioned structure has multiple layers, with the lower layer having a lower density and the upper layer having a higher density. Accordingly, even when a load (from a worker or snow) is applied to the heat insulating layer, it does not deform, and a heat insulating layer having a desired thickness can be provided, thus solving the above-mentioned problems.

〔Effect of the invention〕

In the invention described in claim 1,
Side rising portions 2 are provided on both sides of the long main plate 1 in the width direction.
2 is placed on a layer of heat insulating material C having the same width as the covering stainless steel material laid on the outer surface or inner surface of structure A, and attached at one location approximately in the center. The lower end of the movable tongue piece 5 having a relatively high height is locked to the generally flat plate-shaped suspender body 3 having a through hole 4, and the movable tongue piece 5 is fixed to the length of the suspender body 3 in the longitudinal direction. The movable hanger D is made to be able to slide sufficiently within the range of 1. The movable tongue piece 5 is brought into contact with the side rising part 2 on one side of the covered stainless steel material B, and the hanger main body 3 is attached to the mounting through hole. A plurality of movable suspenders D are fixed to the outer surface or inner surface of the structure A using fixing members 6 via the fixing members 6, and a plurality of movable suspenders D are provided so as to cover the suspender main body 3, and the front insulation One layer of adjacent insulation material C is laid so as to be in contact with the side edge of material C, and the other side of the adjacent coated stainless steel material B on the adjacent insulation material C is laid on the side rising part 2 of one side. The side rising portions 2 are overlapped, and the movable tongue piece 5 is sandwiched therebetween,
A covering in which the rising parts 2 and 2 of both sides are seam-welded to each other to form an expansion joint part 7 which is open on the lower side, and the movable tongue piece 5 can be slid only in the longitudinal direction of the expansion joint part 7. By using a heat insulating envelope made of stainless steel, etc., firstly, it is possible to create a completely watertight covering and has extremely excellent heat insulation performance, secondly, it is extremely effective in terms of maintenance and management, and thirdly, it can be easily expanded and contracted by heat. Fourthly, an extremely strong heat insulating envelope can be provided.

To explain these effects in detail, first, the outer or inner surface of the structure A can be made completely watertight and airtight using the seam-welded coated stainless steel materials B, B, ..., and in particular, the insulation material C can be interposed. By doing that,
By the composition of the heat insulating material C and the covering stainless steel materials B, B,..., it is possible to completely prevent moisture permeation for the first time, and as a result, construction can be performed with extremely excellent heat insulating performance.

In other words, by requiring coated stainless steel material B, by seam welding these coated stainless steel materials B, B, ... and by interposing heat insulating material C inside this material, the heat insulation performance is significantly improved. Due to its insulation performance, it can significantly reduce heating and cooling costs in buildings, etc., making it a particularly good measure for energy conservation.

In addition, since the covering sheet is made of stainless steel, it has excellent corrosion resistance and durability, and can withstand semi-permanent use.In particular, since no maintenance is required, the effect after construction is extremely large. Therefore, even with asphalt insulation waterproofing, which has high waterproofing efficiency, it becomes obsolete after a few years and must be re-waterproofed and re-insulated, resulting in huge construction costs. This is a truly revolutionary invention for the insulation and waterproofing industry. moreover,
Even though stainless steel is relatively expensive, it can provide complete insulation and waterproofing construction at low cost, considering its long durability and no need for maintenance. Furthermore, if the outer surface of structure A is covered with heat insulating material C and coated stainless steel materials B, B, etc., so-called external insulation and waterproofing can be achieved, and structure A, that is, the structure can be protected. The original material can be kept unchanged for a long time, and the durability can be further improved.

At the same time, the airtightness is also perfect;
In conjunction with heat insulation, it can be used to create necessary structures such as fumigated or sterile spaces, or spaces that are completely isolated from the outside air.

Due to the above-mentioned effects, it can be used for coating the inside and outside of structures such as buildings, refrigerators and freezers,
It can be used in an extremely wide range of applications such as chemical plant tanks and grain silos.

Further, in the present invention, the suspender main body 3 of the movable suspender D, in which the movable tongue piece 5 is provided so as to be sufficiently slidable within the range of the length in the longitudinal direction of the suspender main body 3, is attached to the outer surface of the structure A or The movable tongue piece 5 is fixed to the inner surface part and is sandwiched between the adjacent side rising parts 2, 2, and the side rising parts 2, 2 are seam-welded to each other to form an expansion joint part 7. By making the movable tongue piece 5 slidable only in the longitudinal direction of the expansion joint part 7, the covering stainless steel materials B, B, etc. will thermally expand and contract due to external temperature etc., and thermal stress will occur. Due to the opening/closing action of the expansion joint 7 and the sliding action of the movable tongue piece 5 of the movable hanger D, the coated stainless steel materials B, B,... can be freely expanded and contracted in the longitudinal and width directions, and the members thereof to avoid causing any thermal stress to the
This has the effect of reliably preventing deformation and damage caused by thermal stress and the like.

Due to the presence of the movable hanger D, the coated stainless steel materials B, B, ... can be thermally expanded and contracted independently from the structure A, thereby eliminating any thermal strain that may occur locally or as a whole. Can be done. Because it is expandable and retractable in this way, it can withstand vibrations such as earthquakes.
Damage to the covering sheet can be prevented.

Furthermore, in the present invention, the suspender main body 3 of the movable suspender D is fixed on the structure A under the heat insulating material C, and negative pressure (wind pressure, etc.) is applied to pull out the movable suspender D. Even if a load such as snow accumulation or a load such as a holding concrete 9 placed on the top surface of the covered stainless steel materials B, B, etc. is applied, the structure A under the insulation material C will be approximately The lower end of the movable tongue piece 5 is locked to the flat plate-shaped hanger body 3, and it can slide only in the longitudinal direction, and does not move up or down, and the load etc. is transferred to the hanger through the movable tongue piece 5. Since the hanger body 3 is attached directly to the main body 3 and the entire hanger body 3 is fixed on the structure A via the fixing device 6, the covered stainless steel materials B, B, ... are attached to the structure via the movable hanger D. Since it is fixed to material A, it will not peel off easily and can have an extremely strong fixed structure.

In addition, in the movable hanger D of the present invention, the movable tongue piece 5 is made sufficiently slidable within the range of the length in the longitudinal direction of the hanger main body 3, so that the force applied to the movable tongue piece 5 is , is always at the center position of the hanger main body 3, that is, the fixing point by the fixing device 6, and can be made strong against both tension and compression.

This means that the width of the movable tongue piece 5 is smaller than that of the suspender body 3, and it slides approximately at the center of the suspender body 3, so even when a load is applied, it will not be affected by eccentric loads. It has the advantage of being strong and durable.

Further, in the present invention, the lower end of the movable tongue piece 5 having a relatively high height is locked to the substantially flat plate-shaped suspender body 3, and the lower end of the movable tongue piece 5, which is relatively high, is fixed to the outer surface or the inner surface of the structure A.
Since the fixed portion fixed by the fixing tool 6 through the mounting through-holes 4 at several locations is often located approximately directly under or near the movable tongue piece 5, a tensile force is applied to the movable tongue piece 5. However, the bending force (bending stress, etc.) generated in the fixed part of the hanger body 3 is relatively small, and as a result, even if the hanger body 3 is made of relatively thin material, it can withstand strength. It is. Therefore,
In the conventional movable hanger that is fixed at two places on both ends, the movable tongue exists between the fixed parts at both ends, and the bending force due to its tensile force becomes large (the distance between the fixed part and the line of action is large). ),
Although there was a need for the members to be made of thick material, the present invention allows easy construction by fixing in one place approximately in the center, and is also strong, so it is possible to use thin materials.

In addition, most conventional movable hangers have two or more fixing points, which makes fixing work with bolts, etc. extremely troublesome and increases construction costs, but the present invention's component parts With the movable hanger D, the fixation is at least one place, and positioning is easy if it is at one place, making installation extremely simple and quick. As a result, the efficiency of constructing a heat insulating envelope made of coated stainless steel or the like can be greatly improved.

Next, in the invention described in claim 2, the single layer of heat insulating material C in the invention of claim 1 is changed to a plurality of layers of heat insulating material, with the lower layer having a lower density and the upper layer having a higher density. Due to this high density insulation material
Due to the presence of C ₂ , the heat insulating envelope has a relatively hard structure when viewed from the surface side, and it is difficult for workers etc. to stand on the relatively thin coated stainless steel material B, B, ... on the top surface side. , or even if a snow load is applied, the high-density insulation material C ₂ acts as a support, and there is no deformation strain on the coated stainless steel materials B and B. Furthermore, a part of the insulation layer becomes flattened, which causes This can prevent insulation performance from being reduced by half. In particular, since the low-density heat insulating material _C1 is also used, it has the great feature of being able to reduce construction costs compared to constructing everything as a heat insulating material using the high-density heat insulating material _C2 .

Further, other configurations of the present invention are similar to the first aspect of the invention, and the same effects can be achieved.
