Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating envelope that can be made of a heat insulating board of a predetermined length and has extremely excellent heat insulating properties, and has good water resistance (rain protection) and ease of construction. .

Conventionally, various heat insulating plates have been developed in which a heat insulating material such as glass wool or foamed synthetic resin is entirely or partially covered with a metal plate. However, there are disadvantages in that it is extremely troublesome to connect the insulation plates to each other or to attach them to structural materials such as the main building and the roof, and that the insulation effect cannot be fully exerted especially at the attachment (connection) points. Ta. Furthermore, even when heat insulating plates are installed, the connection between the adjacent sections is not completely protected from rain, and it is not possible to mount them firmly. In addition, when such insulation boards are made to the maximum length (10-odd meters or more), there is no need to connect them in the longitudinal direction, but for convenience of transportation and handling, they must be formed at the construction site. Ta. For this reason,
We transport the insulation plate roll forming machine (a device that covers and shapes part or all of the insulation material with a metal plate) to the site,
This required a lot of time to set up the hemming, and the completed long and heavy insulation boards needed to be handled by a large number of people. For this reason, when there are few workers, there is a drawback that work on external structures such as roofs or walls may be hindered, construction may take a long time, and construction costs may become high. Therefore, the present invention aims to cover the upper surface of the main heat insulating plate with notched stripes formed at the lower corners of both sides in the longitudinal direction and up to the middle of the notched strips on both sides with a metal plate. A protrusion is formed above, a large protrusion with a height higher than the protrusion is formed slightly inside the protrusion, and the upper end of the large protrusion is bent inward to form a predetermined protrusion. A groove of a certain depth is formed on the metal plate between the large ridges on both sides near the upper end in the longitudinal direction of the heat insulating plate, and the upper end of the groove is made higher. Cut out the protrusion from the bottom position to the top green, the metal plate on the outside of it, and the protrusion, and remove the bottom end of the main plate.
The length of the removed protrusions and protrusions on the upper end side is cut out, and the grooves are filled with a sealing material, and the cut portion of the main plate on the lower end side of the upper heat insulation board is cut out. It is polymerized and fixed on the protruding stripes and the protruding strip portions, forming a gap between the upper and lower metal slopes, and interposing a joiner with a convex cross section between the heat-insulating slopes, and bringing the outside of the protruding stripes and the notched strips into contact with this. The bolts are installed on the structural material, the adjacent protruding strips are covered with iron washers, the bolts are passed through the washer and the joiner and attached to the structural material, and a cap material is applied between the adjacent protruding strips. By bending the edge green inward, the mutual connection with the heat insulating plates can exhibit a good heat insulating effect, and the connection can be made simple and strong, and the entire outer enclosure can be improved. It can be made to have excellent insulation properties, and the connection point can be reliably protected from rain. Even if the insulation board is of a specified length, the overlapping part of the upper and lower layers can be easily joined, and the joint part can be easily sealed. The rain protection is extremely good, the overall construction is relatively quick, and the construction cost is low, thus solving the above-mentioned drawbacks.

Its structure will be explained with reference to the drawings.

Reference numeral A denotes a heat insulating plate, which is formed to have a predetermined length (its length in the longitudinal direction is about 10 mm or less), and is composed of a main heat insulating plate 1 and a metal plate 2 covering the main plate 1.

This heat-insulating main plate 1 has a fan-flat cross section, has a predetermined width, and has a longitudinal length slightly shorter than the length of the metal plate 2 (the length of overlapping). The main plate 1 is made of glass wool, rock wool, wood wool, foamed synthetic resin, or the like. Inverted L-shaped notch strips 3, 3 are formed in the longitudinal direction at the lower corners of both sides of the main plate 1. A metal plate 2 is formed to cover the upper surface of the main heat-insulating plate 1 and the vertical portions of the cutout strips 3 on both sides of the main plate 1 up to the middle. Projections 4, 4 are bent above both side edges of this metal plate 2, and these projections 4,
A large protrusion 5 with a height higher than that protrusion 4 is slightly inside of 4,
5 is bent, and horizontal protruding stripes 6, 6 are formed that extend inward from the upper ends of the large protruding strips 6, 5. An enlarged portion 7 having a fig-shaped cross section is formed at the tips of the protruding strips 6, 6. In order to cover the main plate 11 with this metal plate 2, the protrusions 4 and 4 bases on both sides of the metal plate 2 are expanded in advance (first
(See the dotted lines in Figure 7), after superimposing the main plate 1,
Narrow the base and shape it as shown by the solid line in Figure 17. The lower end of the metal plate 2 in the longitudinal direction (the upper side that is inclined or vertical when used as a roof or wall) is formed to protrude from the lower end of the main plate 1 (Figs. 6 and 17). reference). A groove 8 is formed by press working on the metal plate 2 between the large protrusions 5 near the upper end of the heat insulating plate A in the longitudinal direction.

In reality, this groove 8 is formed halfway up the inner side of the large protrusion 5. Further, when a bulge 9, which will be described later, is formed on the metal plate 2, grooves 8 are also formed on this bulge 9. This groove 8 is formed to have a substantially constant width. This bulge 9 is formed on the metal plate 2 between the large protrusions 5, 5 as necessary. The flat part and the bulging part 9 of the metal plate 2 are vertically moved in parallel to the upper end side of this groove 8, that is, the upper end side of the metal plate 2 and the winning part 9 between the large protrusions 5, 5. A raised local portion 10 is formed by pressing or the like. The groove 8 has a substantially constant deep round shape from the top surface of the high portion 10 to the bottom surface of the groove 8. Both protrusions 4 on the upper end of the heat insulating board A (the upper side that will be sloped or vertical when used as a roof or wall), the metal plate 2 on the outside thereof, and the protrusion 6 are slightly below the groove 8. It was excised from the position of 1 to the upper edge (Fig. 6,
(See Figure 7). B is a joiner with a convex cross section, which is formed to be long or to a predetermined length, and is made up of a heat insulating section 11 on the upper surface and a bent metal strip superimposed on the lower surface. 12. The height of the protruding parts on both sides of the heat insulating part 11 having a convex cross section is equal to the height of the cutout strip 3 of the main plate 1, and the strip plate 12
It is formed slightly wider than the width of the Reference numeral C denotes structural members such as purlins and selvedges, which are provided in plural at predetermined intervals on the top or side of the structure. A heat insulating board A is placed perpendicularly to this structural member C, and in particular, the upper end surface in the longitudinal direction is placed at a position approximately half of the upper surface of the structural member C (see Fig. 6). Next, joiner B is applied to the side of this heat insulating board A, that is, the three notched stripes (7th
(see figure), and the same heat insulating plate A is brought into contact with the joiner B and joined together. Next, a washer 13 having a hat-shaped cross section is placed on the protrusions 4, 4 of the heat insulating plates A, A, which are provided side by side. And the drill-shaped bolt 14 is the washer 1.
3 is inserted through the joiner B and fixed to the structural member C, and its washer 13 is installed in the structural member C (see Fig. 8). In some cases, a bolt with a protruding shaft is fixed to the structural member C, and the bolt shaft is inserted into the joiner B and the washer 13, and the washer 13 is fixed by screwing it with a nut. The groove 8 is filled with a sealing material 15 (see Fig. 10).The sealing material 15 is made of synthetic resin or synthetic rubber material, has a tape shape, and is slightly thicker than the depth of the groove 8.
Moreover, it is formed to have the same width as the groove 8. Then, the upper end side of the lower heat insulating plate A including the grooves 8, the high part 10 and the sealing material 15 is covered, and the lower end side of the upper metal plate 2 [the part where the main heat insulating plate 1 is not attached to the bottom surface] is covered. Polymerized and fixed~
That is, the metal plate 2 between the large protrusions 5, 5 on the lower end side of the upper-cut insulation board A is superposed on the high part 1 on the upper end side of the lower insulation board A,
It is fixed watertightly with water-resistant glue pet 16, and
The large protrusion 5 on the lower end side of the upper heat insulation board A
Large protrusion 5 on the upper end side [where the protrusion 6 is removed]
The four protrusions of the upper heat insulating board A are joined so as to cover the parts where the protrusions 4 of the lower heat insulating board A have been removed (see Fig. 11). The flat metal plate 2 and bulge 9 between the upper and lower heat insulation plates A, A, that is, the upper large protrusions 5, 5, and the flat metal plate 2 and the bulge 9 between the lower large protrusions 5, 5. A gap 17 is formed between the metal plate 2 and the bulge 9. In this way, the upper heat insulating plates A and A are arranged side by side and approved. Then, the upper and lower insulation boards A,
A washer I3 is placed over the adjacent protrusions 4, 4 at the overlapping location of A in the same manner as described above, and is fixed to the structural member C with bolts 14. D is a cap material formed to a predetermined length, and vertical portions 19, 19 are formed upward from both sides of the flat portion 18, and a horizontal portion 20 is formed from the upper end of the vertical portions 19, 19.
, 20 are formed. Bent parts 21, 21 are bent below the outer ends of the horizontal parts 20, 20, and horizontal edges 22, 22 are provided outward from the lower ends, which are integrally formed. A horizontal portion 20 and a bent portion 2 of an appropriate length (overlapping length) on the upper end of the material D (the upper side that is sloped or vertical when used as a roof or wall).
1. The edge 22 is cut off (see FIGS. 12 and 19). The horizontal parts 20, 20 of this cap material D are placed on the opposing protruding strips 6, 6 of the lower adjacent heat insulating plates A, A, and the flat part 18 and the vertical part 1 on the upper end side of the cap material D
9, 19 [where the horizontal portion 20, the bent portion 21, and the edge 22 are cut] are inserted between the opposing large protrusions 5, 5 of the upper adjacent heat insulating plates A, A (the 12th (See Figure 13). Then, the horizontal parts 20, 20 of the cap material D are placed on the opposing protruding strips 6, 6 of the upper adjacent heat insulating plates A, A, and the lower end side of the cap material D is aligned with the lower end of the cap material D. It is overlapped in steps on the flat portion 17 on the upper end side (see FIG. 14). Then, the bent portions 21, 21 of the upper and lower cap materials D, D are bent inward (fastened) to form the lower part of the protruding strip 6 [the lower surface of the protruding strip 6 excluding the enlarged portion 7]. A gap 23 is formed between the bent portion 21 (see FIG. 5).
. Next, a waterproof adhesive is applied to the overlapped portion of the upper and lower cap materials D (see Fig. 15), and the end edge 2 of the cap material D, which has a cross-sectional shape similar to that of the cap material D,
2], a joint plate 24 formed in a step shape
are iron-bonded, their outer edges are bent, and then they are tightened together (see Figure 1). By repeating these steps one after another, a heat insulating enclosure such as a roof or wall is approved. Next, the effects will be explained. In the present invention, a joiner B is interposed between the heat insulating plates A and A of a predetermined length and installed on the structural member C, and a washer 13 is placed on the adjacent protrusions 4 and 4, and the washer 13 is The bolts 14 pass through and are attached to the structural member C, and the adjacent protruding strips 6, 6 are covered with the cap material ○, and this edge is bent inward, so that the mutual engagement portion between the heat insulating plates A, A, etc. Even if the heat insulating plate A is not formed, it can be easily and easily done by using the joiner B, the washer 13, the bolt 14, the cap material D, etc. from above the heat insulating plate A, without building scaffolding etc., and without requiring any skills. The outer enclosure such as a roof or wall can be quickly constructed, and the protrusions 4, 4 on both sides of the heat insulating board A are pressed and fixed to the structural member C by washers 13, which means that the wind pressure is reduced. Both sides of the heat insulating plate A, which applies the maximum amount of heat, are fixed, and a strong heat insulating outer body that does not come off or scatter due to strong winds etc. can be obtained.

Furthermore, by bending the edges of the cap material D to the protruding strips 6 and joining them together, the connection between the adjacent heat insulating plates A, A can be strengthened. In addition, by fastening the cap material D, rainwater is difficult to enter, but even if rainwater were to enter between the cap material D and the protruding strips 6, the space between the protruding strips 4 and 6 serves as a gutter-like part. Rainwater flows out from the gutter-like part to the eaves, and does not enter the interior, making it possible to effectively shut off rain. In addition, the heat insulating board A is one in which the upper surface of the heat insulating main board 1, which has notched stripes 3, 3 formed at the lower corners on both sides, and up to the middle of the notched strips 3 on both sides are covered with a metal plate 2. As a result, the main plate 1 comes into contact with the structural member C, and the metal plate 2 does not come into contact with the structural member C. By interposing the joiner B between the heat insulating plates A and A and attaching it to the structural member C, the metal plate 2 Even if the outside temperature that is transmitted to 2 changes,
The outside air can be prevented from being transmitted to the structural material C by being blocked by the main insulation board 1, and the joint part is connected to the joiner B.
The large gap between the adjacent protruding strips 6, 6 and the cap material D can substantially block the outside air, resulting in an outer envelope with extremely high heat insulation efficiency. In addition, if the insulation board is made long, it becomes unnecessary to connect it in the longitudinal direction, but it also becomes impossible to transport, and after the preparation work such as transporting and installing the roll forming machine of the insulation board to the construction site, it is necessary to connect the insulation board in the longitudinal direction. The long insulation board A had to be formed on site. However, in the present invention, by making the heat insulating board A have a predetermined length in the longitudinal direction,
It is possible to use all factory-produced products, eliminating the need for setup work such as transporting and installing the molding machine, preventing the drop in efficiency that would otherwise be caused by having to perform molding on site, and improving work efficiency. The price of the insulation board A can be lowered.Furthermore, if the insulation board A is made into a long length of several tens, the weight will increase and a large number of workers will be required to handle it, and the work may not be possible when there are fewer people. However, the work of the present invention, which has a predetermined length, can be easily handled by a small number of people, such as a minimum of two or one person. In addition, in the present invention, the upper end side of the heat insulating board A in the longitudinal direction can be
A groove 8 is formed on the metal plate 2 between the large protrusions 5 and 5, and the upper end side of this groove 8 is made into a higher part 10, and a part of the groove 8 from the lower layer to the upper edge is formed. The protruding strip 4, the metal plate 2 on the outside thereof, and the protruding strip 6 are cut out, and the lower end side of the main plate 1 of that length is cut off. The groove strip 8 is filled with the sealing material 15, and the upper end side is cut out. The cutout lower end of the main plate 1 of the upper heat insulating board A is polymerized and fixed onto the protruding ridges 4 and 6, so even if the sealing material is adjusted slightly up and down in the longitudinal direction of L during installation, the sealing material will not change. 15 is filled in the convex groove 8, and the sealing material 15 can polymerize and fix the upper and lower insulation plates A, A in a watertight manner without coming off from the groove 8. In addition, even if the sealing material 15 is in the form of a belt with a constant thickness, the groove 8 has a substantially constant depth, so the sealing material 15 is placed between the upper and lower insulation plates A and the metal plates 2 of A. The sealing material 15 is filled with a substantially uniform degree of compression.
It can be made highly watertight at any location. Furthermore, by cutting off the upper ends of the protrusions 4 and 6 and the lower end of the main plate 1 as described above, the upper and lower insulation plates A, A can be superposed in a step-like manner very orderly and reliably. In addition, since a gap 17 is formed between the upper and lower metal plates 2, 2, rainwater will blow into the overlapping part that is arranged in the upper and lower steps, but the gap 17 prevents the capillary phenomenon of rainwater. This allows the rainwater to flow out to the eaves side, making the stepped overlapping area better protected against rain. Further, since the upper end side of the groove 8 is further raised and the lower end side of the upper metal plate 2 is polymerized and fixed, the sealing material 15 can be pressed and watertightness can be further ensured at the overlapped portion. In this way, the characteristics of the present invention are that the stepped structure not only provides good protection from rain, but also improves workability and provides excellent heat insulation. In addition, the metal plate 2 of the heat insulating plate A in the present invention has many bent parts, and there are cap members D, joiners B, washers, etc. at the joints, and the section modulus of each member is large, so that the heat insulating envelope It can be made significantly stronger as a whole.
