At the same time, the heat shield sheet covering the entire area between the rafters is fixed to the sheet support portion, and a space forming portion is provided on the side surface of the rafter to form an appropriate gap with the heat shield sheet. A heat insulating material having an appropriate thickness determined by a position is provided, and a cross-sectional structure is provided in which a space between rafters is filled and an earth plate is stretched on the bottom surface of the rafters.

  Thus, the panel is constructed by directly passing between the purlin and the eaves or between the purlin and the main building and between the main building and the eaves, and performs appropriate roofing on the roof base plate. In particular, a heat shield sheet is provided inside, and the upper and lower layers of the heat shield seed have a ventilation space in which air is distributed over the entire surface between the rafters. As a result, an appropriate temperature inside the room (inside the roof panel) is secured. In particular, even if the heat insulating material is thinned by reflection and ventilation of radiant heat, it can have a sufficient heat shielding function.

  Further, the roof panel according to claim 2 of the present invention is the above panel, wherein the roof rafter is extended to the eave portion, the field plate is fixed to the eave portion, and a number of small through holes are formed on the bottom surface of the rafter. The perforated ventilation plate is stretched with an appropriate gap between the heat insulating structure portions.

  Therefore, if the roof is constructed with the above-mentioned roof panel, it can be constructed up to the eaves part at the same time, and it enters the eaves interior space from the small through-holes on the eaves side and the ventilation layer on the back of the outer wall from the eaves boundary. It flows into the ventilation layer.

  The roof panel according to claim 3 of the present invention is such that the surface of the interstices is covered with a decorative board, and the ceiling decoration of the attic room can be performed simultaneously with the construction of the roof.

  As described above, the configuration of the present invention was able to provide a roof panel that was equipped with a heat shield sheet and was excellent in heat insulating function, facilitated the manufacture of a roof panel that uniformed heat distribution, and could also be applied to the eaves portion at the same time. Is.

The top view which cut off part of embodiment of this invention. FIG. FIG.

  Next, an embodiment of the present invention will be described. The roof panel shown in the embodiment is an example in which a heat insulating part and an eaves part are integrally formed.

  The overall width and length are pre-manufactured according to the design standard (182 cm or 200 cm) of the house to be constructed, and the width is equivalent to 1 and the length is equivalent to 3.

  The basic structure of the panel is that the upper surface of roof rafters (hereinafter simply referred to as “rafters”) 1 arranged in parallel at appropriate intervals (corresponding to ¼) is connected by a field plywood 2 of structural plywood to form a panel base. Specifically, the rafter 1 is raised to 12 mm thick plywood (raised material 1a), taking into account the formation of upper and lower layer ventilation portions A and B, which will be described later, on a standard material of W38 mm × H89 mm, The field board 2 uses a 12 mm thick structural plywood.

  The said panel base | substrate differs in the heat insulation structure part 3 of the range installed in the house side, and the eaves part 4 of the range installed in the house outdoor side. Further, the internal structural members are sequentially constructed on the back surface of the base plate 2 so that the entire panel is manufactured.

  The heat insulation structure unit 3 includes a sheet support unit 31, a heat shield sheet 32, a gap formation unit 33, a heat insulating material 34, a dirt plate 35, and a decorative plate 36.

  The sheet support portion 31 is obtained by cutting a trunk edge standard material (W45 mm × H18 mm) to about L90 cm, and an appropriate point distribution such as a position along the side surface of each rafter 1 or an intermediate position between the rafters 1. It adheres to the base plate 1.

  The heat shield sheet 32 is formed of an aluminum sheet whose surface is mirrored, and is fixed to the sheet support portion 31 and stretches over the entire heat insulating portion between the rafters 1 so that no large deflection occurs when stretched. Next, the point distribution of the sheet support portion 31 is determined. A gap between the heat shield sheet 32 and the back surface of the base plate 2 serves as an upper layer ventilation portion A.

  The space | interval formation part 33 is for securing the lower layer ventilation | gas_flowing part B, and adheres the fine material 20mm in height along the contact position with the side surface of the rafter 1 in the heat insulation sheet 32. As shown in FIG.

  The heat insulating material 34 employs a high-performance phenol foam (one type A type phenol foam heat insulating plate) and is fitted between the rafters 1.

  The earthen board 35 connects the lower surface portion of the rafter 1 and constitutes the back surface of the panel base. The decorative board 36 is made of, for example, a 6 mm thick red pine board so that it can be used as a ceiling board in the room (back room).

  The eaves part 4 connects the front end surface of the rafter 1 with a nose cover material (rafter standard material) 41, and opens a gap C at an appropriate distance (about 18 to 25.5 mm) from the front end of the heat insulating structure 3. The base member 43 of the ventilation plate 42 is placed between the rafters 1 so as to coincide with the bottom surface of the base plate, and the ventilation plate 42 is fixed to the bottom surfaces of the rafters 1, the nose masking material 41, and the base member 43, A space D is formed. The vent plate 42 is a calc board (gypsum board) having a large number of small through holes 44 formed therein.

  The rafters 1, the base plate 2, the heat insulating structure 3 and the eaves part 4 may be fixed to each other by means of nailing, using an adhesive, or using both.

  Thus, the roof panel 01 shown in the above embodiment is used for construction including the eaves, and on the ridge side, the roof panel 02 formed only by the heat insulating structure is used, and the purlin a, the main building b, The roof is constructed by passing directly between the main building b and the eaves beam c, and appropriate roofing is performed on the field board 2.

  After being constructed as a roof, radiant heat due to direct sunlight on the roof is reflected by the heat shielding sheet 32, and the upper and lower air vents AB and the heat insulating material 34 block the heat from the outside air and maintain the room temperature. .

  When the heat shield sheet 32 is warmed or cooled by outside air or direct sunlight, an air flow is generated in the upper and lower layer ventilation portions AB. For example, in the summer, when the air in the upper and lower air vents AB is warmed, the air flows upward and rises to the purlin location, and is released to the outside air from the louver formed on the ridge wrap.

  Along with this, the outside air rises in the outer wall space E on the back surface of the outer wall d and enters the eaves space D from the gap C, and also enters the eaves space D through the small through holes 44, and flows into the air flow in the upper and lower layer ventilation portions AB. The outside air that has followed and entered the eaves space D enters the upper and lower layer ventilation portions AB.

  Therefore, the roof panel of the present invention can be constructed as a roof having an excellent heat shut-off function because the roof is easily constructed by the construction, heat is also diffused by the circulation of air in the panel along with reflection of radiant heat. It is.
