Description

  The present invention relates to a roof panel for forming a lower ground of a roof, and more particularly to a roof panel that uses a wooden building material to facilitate construction.

As a construction method for roofs in wooden buildings, in the conventional construction method, a rafter is built between purlins, purlins, eaves girder, a ground plate is stretched on top of it, and a heat insulating material and a sealing member are provided for waterproofing. A method such as placing roof exterior materials such as tiles and roofing boards on the roof was used. However, such a method tends to be expensive as a result of a long construction period in terms of a large number of members and an increase in work at high places.
In order to solve such a problem, a method has been proposed in which a roof panel is prepared in a factory in advance and is transported to a construction site to shorten the work on the construction site.
For example, as a report on the configuration and shape of the panel, a roof panel is formed by attaching a heat insulating material to a plate material, and a wiring groove is provided in the heat insulating material (see Patent Document 1), a basic roof panel and an eaves edge. An example in which productivity is improved by providing a common portion on a roof panel has been reported (see Patent Document 2). Moreover, as a report about the roof panel considered also considering the attachment method, the example which made construction easy using a roof panel, a gusset, and a bracket is reported (refer patent document 3).

However, in these conventional methods, a purlin or a support member having a specific inclined section is required to attach the roof panel at a predetermined angle, and special creation is required for the creation and attachment work. There was a problem that the construction period could not be shortened sufficiently. In addition, the number of parts for creating the roof panel is large, and there are not many special parts for the part, and the roof panel cannot be provided at a low price.

It is possible to provide a roof panel that can be easily constructed without requiring a special purlin or a support member when realizing a roof base.

  The present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an external perspective view of the roof panel of the present invention, FIG. 2 is a sectional view thereof, FIG. 3 is a perspective view and a side view of an I-beam used in the roof panel of the present invention, and FIGS. It is explanatory drawing which shows the manufacture order of a panel. In these drawings, reference numeral 1 is a roof plywood, reference numeral 2 is a ceiling plywood, reference numeral 3 is a heat insulating material, reference numeral 4 is an I-beam, reference numeral 5 is an eaves board, reference numeral 6 is an eaves crosspiece, reference numeral 7 is a crosspiece, reference numeral Reference numeral 8 denotes a ridge fitting, reference numeral 9 denotes a girder fitting, and reference numeral 10 denotes a roof panel.

First, the I-type beam 4 which is a framework of the configuration of the roof panel 10 of the present invention will be described with reference to FIG.
As shown in FIG. 3, the I-shaped beam 4 includes a pair of concave frame bodies (hereinafter referred to as flanges) 41 and a plate member (hereinafter referred to as flanges) that is fitted between the flanges 41 and sandwiched between the pair of flanges 41 from below. (Referred to as a web) 42. As shown in the side view of FIG. 3B, the web 42 is a trapezoidal trapezoidal shape. A short one of the non-parallel opposite sides is perpendicular to the bottom side, and a long one is a horizontal surface of the roof base surface. It intersects with the base at an additional angle β of the inclination angle α. The long side of the trapezoidal parallel opposite side of the I-beam 4, that is, the bottom side is the roof plywood 1 side, and the short side of the trapezoidal parallel opposite side is the ceiling plywood 2 side. Ready-made products can be used for the flange 41 and the web 42. By using a wooden structure beam, a lightweight, sufficient strength and good workability can be produced.

A procedure for manufacturing the roof panel 10 using the I-shaped beam 4 will be described with reference to FIGS.
First, as shown in FIG. 4, the heat insulating material pressing plate 43 is attached to the I-type beam 4. The heat insulating material pressing plate 43 presses the end of the panel 44 made of the heat insulating material 3 so that the heat insulating material panel 44 does not move in the space of the roof panel 10. Also, vent holes are formed in the web 42 to remove burrs and protrusions from the holes so that the subsequent work is not hindered.

  Next, as shown in FIG. 5, a plurality of I-type beams 4 are arranged with spacers. Then, the eaves frame material 6 is affixed to the eave side perpendicular to the bottom side of the web 42, and the crosspiece (spacing material) 7 is inserted between the ridge side sides inclined with respect to the bottom side. Stick.

  Next, as shown in FIG. 6, the roof plywood 1 is attached to the bottom side of the web 42. The thickness of the roof plywood 1 is, for example, 12 mm. Thereafter, as shown in FIG. 7, the roof panel 10 to which the roof plywood 1 is attached is turned upside down and the opening portion is kept upward.

  Next, as shown in FIG. 8, the heat insulating material panel 44 is inserted into the roof panel 10 from the opening portion of the roof panel 10. As an example, as shown in FIG. 2B, the heat insulating material panel 44 has the same thickness (40 mm in this case) as the height of the flange 41 and a width equal to the distance between the flanges 41, and the width is the web 42. It is composed of one sheet having a thickness equal to the distance between them and a thickness of 40 mm, and one sheet having a width equal to the distance between the webs 42 and a thickness of 100 mm. As a result, the heat insulating panel 44 can be packed to a predetermined thickness without any gap, and a sufficient heat insulating effect can be obtained. When the heat insulating material panel 44 is inserted, the lower part of the heat insulating material panel 44 is caught by the heat insulating material pressing plate 43 and stopped, so that a slight gap space can be formed between the heat insulating material panel 44 and the roof plywood 1. This space can be used for ventilation or for wiring. The heat insulating material panel 44 is made using, for example, polystyrene foam, etc., is excellent in heat retention and air permeability, and is lightweight.

  Next, as shown in FIG. 9, the ceiling plywood 2 is attached to the ceiling side. The thickness of the ceiling plywood 2 is 9 mm, for example. The ceiling plywood 2 is slightly shorter than the length of the roof panel 10 for ventilation, and the I-shaped beam 4 is exposed at the eaves portion. Thereby, air is sucked into the roof panel 10 from here, is discharged from the ridge portion through the gap space between the heat insulating material 44 and the roof plywood 1, and is naturally ventilated. Finally, a roof panel 10 as shown in FIG. 1 is realized. In addition, it is also possible to affix the eaves board 5 to this part and to confine ventilation by concealing the I-type beam 4.

  As described above, the roof panel 10 of the present invention is composed of the I-shaped beam 4, the roof plywood 1, the ceiling plywood 2, and the heat insulating material 3. It is lightweight, but has sufficient strength and has excellent heat retention and airtightness.

Next, FIG. 10 shows a schematic external view when a gable-shaped roof base is formed using the roof panel 10 of the present invention, and FIG. 11 shows a side view of the roof base.
Since the roof panel 10 has sufficient strength, as shown in FIG. 10, a plurality of the roof panels 10 are arranged in the width direction, and the roof panel 10 on the other side or the adjacent roof is used in the ridge portion using metal fittings. By fastening to the panel 10, fastening to the girder at the girder part, and connecting and fixing to each other, it can be made independent without providing rafters, special purlins and support members, as shown in FIGS. A simple roof base can be constructed in a relatively short time. For fastening, the ridge fitting 8 and the girder fitting 9 are used, but details of these fittings will not be described in detail here.
As can be seen from FIG. 11, when the inclination angle between the roof base surface and the horizontal plane is α, the abutment angle of the roof panel 10 at the ridge, that is, the side surface of the web 42 of the I-type beam 4 described above. The angle β between the long side of the opposite side of the unequal leg trapezoid and the base is the remainder angle β of the inclination angle α.
The obtained roof base is light and inexpensive, and has the advantage that a large space can be created in the back of the hut because rafters and purlins can be omitted.

  The roof panel of the present invention is lightweight, excellent in heat retention and breathability, has sufficient strength, can be manufactured at low cost using off-the-shelf materials, and a special purlin is used when realizing a roof base. It can be used efficiently for a wide range of architectural roofs, and it can be used effectively for a wide range of architectural roofs. have.
