The roof base panel A is the above heat insulating material. 2 is a plurality of downward block-like arrangements parallel to the rafters 23 arranged so as to be fitted between the adjacent rafters 23 of the hut assembly 20, and the block-like heat insulating materials 2 are respectively parallel to the rafters 23. Single or plural, in this example, it is assumed that a plurality of vent holes 8 are penetrated.

  That is, in this example, the field board 1 is a structural plywood having a thickness of about 1 cm in the size of a so-called sub-rock plate having a long side of about 1.8 m and a short side of about 0.9 m. A plurality of heat insulating materials 2 are used on the back surface, for example, the long side is set to about 0.9 m in width corresponding to the short side of the base plate 1, and the short side is set to 0 in width corresponding to the arrangement pitch of the rafters 23. 4 pieces of block-shaped heat insulating material 2 of about 45 m intersecting the long side of the base plate 1 and arranged parallel to the short side, and the rafters according to the width of the rafters 23 between the heat insulating materials 2 The heat insulating material 2 of this example is arranged in parallel so as to form the groove 10, and the heat insulating material 2 of this example has, for example, a base 3 and two upward protrusions 6 on both sides of the base 3. A wide groove is formed between the two upward protrusions 6 and a supporting protrusion 7 is formed at the same height as the upward protrusion 6 in the longitudinal middle of the wide groove. By disposing, an appropriate synthetic resin such as polystyrene, urethane, phenol, etc., such as expandable beads, is foam-molded at an expansion ratio of, for example, about 30 times so that the portions other than the support protrusions 7 have the same cross-sectional shape in the longitudinal direction. In particular, it is made of a closed-cell foamed synthetic resin, and the upper end surface of the upward projecting ridge 6 with respect to the lower surface of the base plate 1 is formed at one end of the half-width open groove 9 of the rafter 23 and the heat insulating material 2. In order to arrange the rafter grooves 10 in accordance with the width of the rafters 23, the arrangement is performed by fixing them by fixing means such as bonding, for example. When the wide groove is closed by the base plate 1, a plurality of, in this example, two wide vent holes 8 are formed so as to penetrate between the long sides of the roof base panel A.

  In the heat insulating material 2 of this example, slits 4 are further formed on both sides of the base portion 3 so as to be formed downward, thereby forming bullet splays 5 separated from the base portion 3 on both sides thereof, and between the adjacent rafters 23. When the heat insulating material 2 is fitted, the elastic ribs 5 are elastically adhered to the vertical surfaces of the rafters 23 on both sides in the width direction, and the heat insulating material 2 is closely fitted between the rafters 23. Can be hermetically sealed by these heat insulating materials 2.

  The above-mentioned heat insulating material 2 of the roof base panel A is a butt compression means for adjoining each other on at least one opposed end face, in this example, the long side of the field board 1 and the opposed end face of the short side of the heat insulating material 2. The butt compression means in the roof base panel A of the present example provided with the vent hole 8 is arranged in a surrounding shape on the indoor side between the rafters 23 of the vent hole 8, thereby The cabin structure 20 and the lower room are shut off on the indoor side of the vent hole 8.

  The butt compression means of this example is formed by the transverse transverse rib 11 slightly projecting from the edge of the base plate 1 arranged so that the two end faces in the width direction are connected in series with the end face of the heat insulating material 2. is there.

  That is, the butt compression means of this example is separated on one side or both sides in the longitudinal direction of the foamed heat insulating material 2, on the end faces on both sides in this example, on the base 3, and on both sides in the width direction in this example. The side ribs 11a are protruded from the end surface of the projecting ridge 5 in the longitudinal direction of the heat insulating material 2 with a small width of, for example, about 1 to 3 mm, and the base 3 end surface of the heat insulating material 2, particularly at the lower part thereof, Similarly, the bottom rib 11b protrudes in the longitudinal direction of the heat insulating material 2 with a slight width of about 1 to 3 mm, and the side rib 11a and the bottom rib 11b are continuously connected to form the vent hole 8 in a surrounding shape. The ribs 11 are adjacent to each other and cross in the direction. The rib 11 in this example is formed by integrally molding the heat insulating material 2 at the time of foam molding, and the width thereof is, for example, the same width or variable width of about several mm to several cm. In the butt compression described later, they face each other in the same shape at the same position so that the ribs 11 can be pressure-bonded in a state of mutual surface contact, and the width of the heat insulating material 2 is set to the base plate. The rib 11 has a width matched to the short side of 1, particularly a width that matches the short side, so that the rib 11 extends in the out-of-plane direction according to the protruding width from the opposite end surface of the base plate 1, particularly the end surface on the long side. It is supposed to protrude.

  The roof base panel A of the present example formed in this way is a butt compression means for the roof assembly 20 from its eaves to the ridge, in this example, a rib that crosses the heat insulating material 2 in the width direction. By fixing 11 as a pressurized state, at least the roof base panels A adjacent in the roof inclination direction are sealed to each other by the elastic compressibility of the butt compression means, and used to insulate the roof of the building. is there.

  That is, as shown in FIG. 8, the roof base panel A of this example has half-width open grooves 9 of the rafters 23 at both ends thereof placed on the rafters 23 and receives the rafters 23 in the rafter grooves 10. By nailing from the upper surface of the base plate 1 to the rafter 23, for example, the block-like heat insulating material 2 is first fitted between the rafters 23 on the eaves side excluding the ridge portion, and the ventilation holes 8 of the heat insulating material 2 are formed. A plurality of lower side sheets are placed and fixed sideways along the eaves so as to face the roof inclination direction, and then arranged in a staggered manner on the roof base panel A that has been placed and fixed in advance. As is done, the roof base panel A at the upper side of the ridge is pressed against the long side of the roof base panel A, the long side of which is placed and fixed in advance, along the inclined surface of the roof, in an end pressing manner. Pressurize downward in the inclined direction and The butt compression means of the end faces of the heat insulating material 2, in this example, the ribs 11 arranged on the indoor side of the vent hole 8 are pressure-bonded to each other by the downward pressure applied by the pressurization. In this way, the space between the heat insulating materials 2 of the roof base panel A is hermetically sealed so that the air permeability of the roof made to be air-permeable is not impaired, and the lower part of the roof 20 The indoor and outdoor are shut off to ensure high heat insulation. The roof base panel A can be placed on and fixed to the eaves portion. However, when the eaves side is removed from the eaves side as shown in this example, Finally, the roof base panel A may be disposed on all the roof structures 20 by mounting and fixing the roof base panel A last. At this time, when the long side of the roof base panel A exceeds the width of the hut 20, it is the same after cutting at the center position of the rafter groove 10 so as to form the above-mentioned one-side open groove 9 at the cut end and matching the remaining dimensions. What is necessary is just to make it mount and fix.

  As described above, the short side of the heat insulating material 2 has a width dimension that matches the arrangement pitch of the rafters 23, so that the roof base panel A is placed on the rafters 23 in a hooked manner on the one-side open groove 9 thereof. In addition, if the roof rafters 20 are arranged in the roof assembly 20 so as to receive the rafters 23 in the respective rafter grooves 10, the heat insulating material 2 of the roof base panel A placed and fixed in a staggered manner is the vent hole of each heat insulating material 2 at the upper and lower sides, respectively. 8 and the positions of the ribs 11 of the abutting means arranged on both end faces coincide with each other, and the ventilation holes 8 can communicate from the eaves side to the ridge side of the roof inclined surface to provide roof ventilation and the ventilation holes 8. The ribs 11 of the abutting means arranged so as to cover the inside of the room are elastically compressed with each other in a surface contact state, and the airtight sealing is performed.
