[0002]

[Prior art]

 Mats with high elasticity, such as rock wool and glass wool, are widely used as building insulation materials because they have excellent performance such as fire resistance, heat insulation, soundproofing, economy, moisture resistance, and durability. .

The structure of this type of conventional mat will be described with reference to FIGS. 3 and 4. The mat 1 shown in FIG. 3 is configured such that an insulating material 2 made of an inorganic fiber such as rock wool or glass wool is wrapped with a jacket material 3 and a sheet material 4. As shown in the figure, the outer covering material 3 covers the front surface 5 and both side surfaces 6 and 6 of the heat insulating material 2, and both ends of the outer covering material 3 are not folded back to the back surface 7 side of the heat insulating material 2. In addition, the bent portions 8 and 8 are directed outward.

The sheet material 4 is provided along the back surface 7 of the heat insulating material 2, and both ends thereof are folded portions 9 and 9 which are folded back so as to surround the folded portions 8 of the outer covering material 3. . Then, a predetermined adhesive 10 is arranged on the back surface 7 of the heat insulating material 2 and the bent portions 8, 8 of the jacket material 3 to bond the sheet material 4 thereto.

In the mat 11 shown in FIG. 4, the sheet material 4 is heat-insulated by the adhesive 10 with the both ends of the outer covering material 3 being folded back portions 12 and 12 which are folded back to the back surface 7 side of the heat insulating material 2. It is adhered to the back surface 7 of the material 2 and the folded-back portions 12, 12 of the jacket material 3. Reference numeral 13 is a protruding portion.

The mats 1 and 11 having such a structure usually have a thickness of about 55 to 100 mm in order to ensure the heat insulating performance, and packing them one by one is bulky and inconvenient to handle. Is. In consideration of this, in order to facilitate transportation and storage, a plurality of mats 1 and 11 are compressed upward and packaged and sold on the market.

Specifically, the mat manufactured and sold by the applicant of the present application has a density of 40 ± 10 kg / m ² , a thickness of 55-100 mm, a width of 270-435 mm, and a length of 1360 mm. 8 to 19 mats are kept in a compressed state and transported and stored as one package.

A compression packing device 15 as shown in FIG. 5, for example, is used for the compression packing of the mat. This compression packing device 15 stacks a plurality of mats 1, 1, ... Commercialized as shown in the figure, and applies a load from above with a press plate 15a to put the mats 1, 1, ... into a compressed state. To do. Next, the mats 1, 1, ... Are pushed by the pusher 16 into the space formed by the guide plate 15b arranged at the front end of the compression packing device 15 and the lower guide part 15c, and the guide plates 15b and 15c Insert into the polyethylene packing bag 17 placed at the tip.

[0009]

[Problems to be solved by the device]

 By the way, when the above-mentioned structure for compressing and packing the mats 1 and 11 using the compression packing device 15, there are the following problems. As described above, the mats 1 and 11 only have the outer covering material 3 coated on the surface 5 of the heat insulating material 2 and are not bonded to each other, so that there is play therebetween. Therefore, when the mats 1 and 11 are inserted into the packing material 17 via the guide box 16, the mats 1 and 11 in the guide box 16 exert a restoring force and play on the outer cover material 3. If so, a large frictional force acts on the contact surface between the guide box 16 and the jacket material 3, causing peeling, wrinkles, or tears of the jacket material 3. In the worst case, the jacket material 3 is left on the guide box 16. Becomes Further, since the sheet 4 of the mat 1 located at the lowermost portion also contacts the lower guide plate 15c, a frictional force works also in this portion when the pusher 16 pushes it in, and the same phenomenon as that of the above-mentioned jacket material 3 is exhibited. If the outer covering material 3 is peeled off or torn, the mats 1 and 11 become defective products and there is an economic loss. On the other hand, the mat 1 has a double structure in which folded portions 9 are provided at both ends of the sheet material 4 and the bent portions 8 of the outer covering material 3 are interposed, and the contact agent 10 is arranged between them. Therefore, the structure is rich in rigidity and thick. For example, when the mat 1 is used as a heat insulating material on a wall, when the folded portions 9 are mounted between the studs, the folded portions 9 on both sides of the stud overlap each other. For this reason, the flatness of the surface of the sheet material 4 is lost, and a step and a curvature of the construction surface occur during the interior material construction. The mat 11 has a similar problem. Particularly, in the case of the mat 1, since the adhesive 10 is disposed on the bent portion 8 and the folded portion 9 as described above, the adhesive 10 leaks to the outside at the time of manufacturing and compression packing, and the manufacturing device and the compression device are compressed. May stain packing equipment. As described above, the mats 1 and 11 have no adhesive on the surface 5 of the heat insulating material 2 and the outer covering material 3, so that the outer covering material 5 is peeled off or torn during the construction, so that the desired heat insulating performance is obtained. There are things I can't expect.

In order to solve such a problem, the present invention prevents peeling, wrinkles, tears, etc. of the outer covering material in a process of packing a plurality of mats in a compressed state, and thus in a good state. It is an object of the present invention to provide a mat that can be packaged and that can exhibit desired heat insulation performance during construction and is easy to construct.

[0011]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is an inorganic fiber in which a heat insulating material of inorganic fiber is covered with a covering material and a sheet material, adhered at a sheet material portion, and projecting pieces are formed at both ends of the sheet material. The mat is characterized in that the heat insulating material and the covering material are adhered to each other on the surface portion of the heat insulating material.

[0012]

[Action]

 According to the mat of the present invention, the surface portion of the heat insulating material is bonded to a part of the covering material, so that when the plural mats are compressed and packed, the restoring force of the mat in the guide box is reduced. Even if a large frictional force acts on the contact part between the guide box and the outer covering material, the outer covering material can be prevented from peeling, wrinkles or tears, and multiple mats can be compressed and packed in the packing material.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view for explaining a mat according to a first embodiment of the present invention, and FIG. 2 is a sectional view for explaining a second embodiment.

The mat 20 of the first embodiment shown in FIG. 1 is configured so that a heat insulating material 21 is surrounded by an outer covering material 22 and a sheet material 23, and these materials are the same as conventional ones. . That is, the heat insulating material 21 uses an inorganic fiber such as rock wool or glass wool.

As the outer cover material 22, a known material such as kraft paper, a plastic sheet such as polyethylene, or an aluminum-processed plastic sheet such as an aluminum vapor-deposited or aluminum foil-attached plastic sheet is used. The front surface 24, both side surfaces 25, 25, and the end portion of the back surface 26 are covered so as to wrap. Then, the surface 24 of the heat insulating material 21 and the outer covering material 22 are subjected to a plurality of spot adhesions 27 by means of an adhesive means such as asphalt, hot mel, or an adhesive, so that the outer covering material 22 is exposed on the surface of the heat insulating material 21. It is glued to 24. In the illustrated case, an adhesive is used for spot adhesion 27.

On the back surface 26 of the heat insulating material 21, the sheet material 23 is formed with protrusions 28, 28 with both ends thereof protruded by a predetermined length via an adhesive means such as asphalt, hot melt, or adhesive. Then, the entire surface is bonded 29 to integrate the heat insulating material 21 and the sheet material 23. However, instead of the whole surface adhesion 29, for example, a plurality of strips of adhesion can be adopted so that the heat insulating material 21 and the sheet material 23 are not easily separated. As the sheet material 23, a known material can be used, and in addition to kraft paper, a flexible sheet material made of the same material as that of the outer covering material 22 can be used.

The mat 30 of the second embodiment shown in FIG. 2 has a configuration slightly different from that of the mat 20 described above. That is, the difference is that the outer covering material 22 is bonded 31 to the entire surface 24 of the heat insulating material 21 through an adhesive means such as asphalt, hot mel, or adhesive.

Although not shown in the drawings, the means for adhering the outer covering material 22 is not limited to the first and second embodiments, and the outer covering material 22 can be heat-insulated uniformly by, for example, plural lines of adhesion. The surface 24 of the material 21 can be adhesively coated.

Since the outer covering material of the mat having such a structure is at least partially adhered to the surface portion of the heat insulating material, the outer covering material can be evenly adhered to the surface of the heat insulating material without play. . Therefore, during the process of stacking a plurality of mats and packing them in a compressed state, peeling, wrinkles, and tears of the covering material can be prevented, and the packing can be compressed and packed to prevent defective products.

[0020]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

Since the outer covering material of the mat is partially bonded to the surface portion of the heat insulating material, the outer covering material has no uniform play. Therefore, even if the mat's restoring force is applied in the guide box, a large frictional force does not work on the contact part between the guide box and the outer covering material, so that peeling, wrinkling, or tearing of the outer covering material does not occur. Can be packed in a packing bag. In addition, it is possible to prevent breakdown of the compression packing device.

It is possible to pack a mat without peeling, wrinkles, or tears in the outer covering material, and to provide a mat exhibiting a desired effect as a heat insulating material.

Since the mat has only the projecting portions of the sheet material at both ends of the sheet material, the mat can be installed on the stud surface without a step, and is superior in workability to the conventional mat having a double structure and being rich in rigidity.

Similarly, since the sheet-shaped both ends have the protruding portions, the adhesive is prevented from leaking out and the manufacturing apparatus is not polluted as compared with the conventional mat.

Since the outer covering material is adhered uniformly and without play, external contact during the construction or after the construction becomes strong, and peeling or tearing of the outer covering material can be prevented, and a desired heat insulating state can be obtained. Can be kept.
