Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating envelope which has particularly excellent heat insulating performance, good rust prevention at the overlapping end, excellent durability, and good watertightness and strength.

BACKGROUND ART Conventionally, heat insulating enclosures such as various roofs or walls have been constructed using heat insulating building boards made of folded metal building boards with a heat insulating material adhered to the lower surface thereof. As shown in Fig. 8, the overlapping installation configuration of the heat insulating building board is such that the top of the crest a of the heat insulating building board, which is an example of a heat insulating building board having a heat insulating material affixed to the entire lower surface, is attached to the adjacent heat insulating building board. When applying polymerization to the top of the yamabushi section on the other side, since the insulation material is pasted, it is not only difficult to perform polymerization, but also the overlapped area often does not adhere well, resulting in a decrease in insulation performance. was there.

In addition, if the insulation material is attached to the sloped edge of the yamabushi section, rainwater will seep in from there, making it difficult to shut down the rain, and the insulation performance of the insulation material that contains rainwater will be significantly reduced by half. There was a point. Also, as shown in Figure 9, if the insulation material of the upper mountain bush section is appropriately cut and polymerized, polymerization will be easier, but in actual construction, there will be a gap between the ends of the insulation material ( There was a drawback that a few parts (11 to 10 parts) opened and condensation occurred due to the cold bridging effect. In addition, the sloped edges are often exposed to rainwater and are particularly prone to corrosion, resulting in poor rust prevention treatment and a drawback that the durability is halved.

Therefore, in the present invention, outwardly upwardly inclined parts are formed on both sides of the bottom part, a stepped part is formed above the inclined part, a narrow top part is formed outward from the upper end of the stepped part, and An inclined edge is formed downward outward from the outer end of the narrow top part, and an upper folded edge is bent from the lower end of the inclined edge so as to be substantially in close contact with the inclined edge, and outward from the upper end of the other inclined part. A bottom part 1 of a metal construction board, which has a wide top formed at the top, a downwardly inclined edge outward from the outer end of the wide top, and a gap formed by bending the folded edge below the bottom end. Both 1'fi oblique part 1 step part.

An insulating building board with heat insulating material attached to the back of each of the narrow top, the sloped edge on the narrow top side, and the upper folded edge is placed on the structural material, and the steps, narrow top, and slope of the heat insulating building board are edge,
The lower folded edge, stretch edge, and wide top of the insulation building board adjacent to the upper folded edge are overlapped, and the insulation material on the back side of the upper folded edge is applied to the sloped part of the adjacent insulation construction board. By crimping the insulation material on the bottom surface, the insulation performance is particularly excellent, and the overlapping edges are extremely rust-proofed, making it possible to have long-term durability and excellent watertightness and strength. This eliminates the above-mentioned drawbacks.

The structure will be explained with reference to the drawings.

A stepped portion 3 is formed from the upper end of the oblique portion 2 around the bottom.

It is formed at the same height as the inclined portion 2 (on the left side in FIGS. 5 and 7). A substantially horizontal narrow top portion 4 is provided outward from the upper end of the stepped portion 3, and a downwardly inclined slanted edge portion 5 is formed outward from the outer end of the narrow top portion 4.

A beveled edge part 8 is formed outwardly and downwardly from the outer end of the wide top part 7, and is slightly (approximately 2 to 5 degrees) steeper than the inclination of the inclined part 2 extending to the step part 3. .

A folded edge 9 lower than the lower end of the inclined edge 8 is bent, and the inclined edge 8. An appropriate gap 10 is formed between the lower folded edge 9 and the lower folded edge 9. That slope 1tQB

A length of metal construction board is constructed. When the width of the bottom portion 1 is wide, a plurality of chevron-shaped bulges 11 (see FIGS. 1, 4, and 7) are formed in a bent manner.

The sloped surfaces on both sides of the chevron-shaped bulging portion 11 are formed between the slope portions 2 of the seven wide top portions, and the upper surface thereof is formed between the wide top portion 7 and the like.

The upper side and lower side of the upper folded edge 6 and the lower folded edge 9 refer to the concept of folding upward or downward.

Next, the effects will be explained.

In the present invention, inclined parts 2, 2 are formed on both sides of the bottom part 10, and a step part 3 is formed above the inclined part 2, and the step part 3 is formed from the upper end of the step part 3. A narrow top portion 4 is formed outwardly, a sloped edge portion 5 is formed outwardly and downwardly from the outer end of the narrow top portion 4, and a folded edge 6 above the lower end of the sloped edge portion 5 is bent to form a sloped edge portion. 5, and forms a wide apex 7 outward from the upper end of the inclined part 2 on the other side, and forms a downwardly sloping edge 8 1 outward from the outer end of the wide apex 7, and below the lower end. A bottom part of a metal construction board with a folded edge 9 bent to form a void part 1o 1 both inclined parts 2.2 stepped parts 3 narrow top part 4
A heat insulating building board A with a heat insulating material 12 affixed to the back side of each of the inclined edge 5 on the narrow top 4 side and the upper folded edge 6 is used as a structural material 13.
Place the lower folded edge 9 inclined edge 8 wide top 7 of the insulation building board A adjacent to the stepped part 3 narrow top 4 sloping edge 5 upper folded edge 6 of the heat insulation building board A. The insulating material 12 on the back side of the upper folded edge 6 is superposed and crimped to the insulating material 12 on the lower surface of the inclined part 2 on the other side of the adjacent insulating building board A.
As a result, firstly, the heat insulation performance of the polymerized part is particularly excellent, and secondly, the rust prevention of the polymerized end part is extremely good, and in turn, long-term quality assurance is possible, making it extremely durable. Thirdly, it can completely prevent the occurrence of scratches on the slope during polymerization construction, etc. Fourthly, it can improve watertightness (rain sealing), and fifthly, it can be used as an insulating building board. It has many functions and effects, such as being able to adjust the dimensional error of A, orderly and reliably constructing it, sixthly increasing the overall strength, and seventhly improving workability.

To explain the effect in detail, by crimping the outer surface of the heat insulating material 12 on the back surface of the upper folded edge 6 with the heat insulating material 12 on the lower surface of the other side (IJ oblique portion 2), the crimping causes the The density of the heat insulating material 12 becomes higher, the amount of heat loss through flow can be significantly reduced, and the heat conduction resistance value can be increased, and the lamination of the heat insulating material 12 and the metal plate provides a heat insulating envelope with extremely excellent heat insulation performance. Furthermore, with such excellent insulation performance, there is no cold bridge part, and it is possible to prevent condensation from occurring over the entire back surface of the insulation building board A, and also to provide sound insulation. Good sound insulation effect can be achieved.Furthermore,
If the heat insulating material 12 is made of nonflammable rock wool or the like, the pressing portion can have a fireproof structure that does not easily burn.

In addition, the corrosion of the polymerized portion generally starts from the edges, and the battery action corrosion (commonly known as "electrolytic corrosion") quickly spreads to the entire polymerized portion, but from the outer edge of the large top 7. By forming an outwardly downward inclined edge 8 and bending the lower folded edge 9 from the lower end, the lower folded edge 9
The edges of the insulation building board A are simply polymerized and become present inside the polymerization point, making it possible to minimize the proportion of exposure to rainwater, thereby making the edges of the insulation building board A extremely resistant to corrosion. The polymerized portion as a whole has excellent corrosion resistance, and its durability can be maintained over a long period of time. In recent years, there has been a particular demand for insulating envelopes such as roofs that are corrosion resistant and durable, and specifically, warranties of 100% to 100% have changed from the traditional 3 to 5 year warranty. The present invention can satisfy the requirement for durability guaranteed for 20 to 20 years. Furthermore, in the present invention, since the heat insulating material 12 is not present at the end where the metal plate overlaps from above, the end of the metal plate and the heat insulating material may separate from each other, or rainwater may enter the heat insulating material from there. This can prevent drawbacks such as a decline in insulation performance. Furthermore, by bending the lower folded edge 9 from the lower end of the inclined edge 8, it is possible to perform construction without scratches on the surface of the inclined part 2 of the three stepped parts during overlapping construction, and the appearance is extremely good. It can be made to have excellent corrosion resistance and corrosion resistance. Furthermore, since the folded edge 9 below the lower end of the inclined edge 8 is bent to form the void 10, the void 10 will always be present at the overlap location even if the overlap is performed. This makes it possible to prevent the capillary phenomenon of rainwater and reliably block the intrusion of rainwater from the ends of the overlapped parts, resulting in a heat-insulating envelope with excellent rain-proofing (watertightness). By the way, coil steel sheets, which are the base material for forming conventional construction boards, have a tolerance dimension on the plus side.
When this material is used for roll forming, the ends (sloped edges) of the architectural boards are often formed with a wide width, resulting in variations in product dimensions, reducing the product value by half, and making it difficult to construct the construction board. However, in the present invention, the lower folded edge 9 is only widened, and the width of the ends of the overlapping Yamabushi parts becomes irregular, making it impossible to roof. This allows for the construction of a heat insulating enclosure such as a roof or wall in an orderly and reliable manner.

In addition, the ends of the standard coil mesh plate generally have better rust prevention treatment than other parts, and since there is no intervening slick, good rust prevention can be achieved.

In addition, by bending the lower folded edge 9 from the lower end of the inclined edge 8, the section modulus is increased compared to only the inclined edge 8, and the strength of the overlapping end and the entire overlapping portion is significantly strengthened. The lower folded edge 9 of the inclined edge 8 is housed in the stepped portion 3 of the adjacent heat-insulating building board A, thereby providing an elegant appearance and a structure that is strong against wind pressure and the like. Further, when the lower folded edge 9 of the inclined edge 8 is housed in the stepped portion 3 in this manner, the outer surface thereof becomes flat, making it difficult for rainwater to enter. In addition, polymerization can be performed simply by placing it from above, and if a heat insulating material is attached to the back side as in conventional polymerization (see Figure 8), polymerization will not adhere even if a worker steps on it. It is possible to provide a heat insulating envelope that is significantly easier to construct than the conventional method.
