Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roof panel used as a constituent member of a wooden house or the like.

[0002]

[Prior Art]

 In view of the shortage of workers and the soaring construction costs in recent years, there is a tendency for the roof panels to be unitized as much as possible. It has become common to mount the roof panel on the building body side by hoisting it with a crane truck and fixing the rafters on the upper side of the main building with a predetermined roof slope.

FIG. 5 shows a conventional fixing structure of such a unitized roof panel and a purlin. In the figure, the roof panel 25 is provided with a base plate 26 whose upper surface is tiled in advance in a factory or the like, and a rafter 27 framed on the lower surface of the base plate 26. A girder receiving material 29 in the longitudinal direction of the purlin is fixed to 28. A purlin 30 is fixed along the H steel 31 arranged on the eaves side of the building body, and a girder member 32 is attached along the upper surface of the purlin 30. In addition, 37 is a top plate (ALC plate) installed on the H steel 31.

The girder material 32 and the girder receiving material 29 are provided with bolt holes 33 and 34 penetrating the same members in the horizontal direction, respectively. Therefore, in the prior art, as shown by phantom lines in FIG. The roof panel 25 is placed on the girder material 32 so that the girder support material 29 is attached to the side surface of the 32, and the bolt 35 is inserted into the bolt holes 33 and 34, and the bolt 35 is fixed with the nut 36. The roof panel 25 was fixed to the purlin 30 side by tightening.

[0005]

[Problems to be solved by the device]

 However, in the above conventional technique, the girder material 32 and the girder support material 29 are fastened by the bolts 35 penetrating in the horizontal direction, so that one worker enters the ceiling space 38 and The bolt 35 must be inserted into the bolt holes 33 and 34, and another worker must tighten the bolt 35 protruding toward the eaves side with the nut 36, which is extremely difficult for the roof panel 25 installation work. It took time.

In view of the above situation, an object of the present invention is to enable only one worker from the eaves side to perform the work of installing the roof panel, and to reduce the construction labor.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the technical means taken by the present invention comprises a panel frame 3 whose upper surface is tiled on a panel frame 3 framed by rafters 2, and said rafters 2 are on the eaves side of the building body 12. In the roof panel that is fixed to the upper surface side of the purlin 14 with a predetermined roof slope, a recess 7 is provided on the lower surface side of the rafter 2 in the roof flow direction, and a purlin 14 longitudinal girder 6 is provided. The cross section is installed between the rafters 2 so as to be accommodated in the recesses, and bolt holes 9 for fastening the bolts 22 to the purlin 14 side are vertically provided in the girder member 6 thereof.

[0008]

[Action]

 The girder material 6 erected between the recesses 7 of the rafters 2 is provided with bolt holes 9 for fastening the bolts 22 to the purlins 14 on the eaves side of the building body 12 in the vertical direction. 22 bolt holes 9 can be inserted and tightened from the eaves side by one person.

[0009]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In FIGS. 1 to 4, reference numeral 1 denotes a roof panel used in this embodiment, which is mainly constituted by sticking a field board 4 on a panel frame 3 framed by a rafter 2 having a rectangular cross section. Flat roof tiles have been installed on the upper surface of the factory in advance through a waterproof sheet in factories. In addition, 5 is a purlin, and is attached to the lower surface side of the base plate 4 so as to form the upper edge of the roof panel 1 in the roof flow direction.

Reference numeral 6 denotes a girder material having a rectangular cross section. In this embodiment, the girder material 6 is attached to the roof panel 1 side in advance in a factory or the like. That is, a pair of rafters 2 and 2 facing the roof flow direction are formed with notches 7 in the shape of a right-angled triangle in a side view, and the girder 6 has a cross section of both ends of the girder 6. The rafters 2 and girders 6 are arranged so as to be housed in the right-angled corners, and by connecting the vertical side surfaces of the rafters 2 and the girders 6 with the L-shaped mounting metal fittings 8, the pair of rafters 2 and 2 can be firmly erected. It has become. In addition, a bolt hole 9 for bolting to a purlin 14 side described later is provided at a predetermined position in the longitudinal direction of the girder member 6 so as to vertically penetrate therethrough.

The angle θ formed by the lateral surface 10 of the recess 7 and the lower surface of the rafter 2 is set to be the same as the roof slope of the roof panel 1, and therefore the roof panel 1 is set to a predetermined roof slope. Then, the horizontal surface 10 of the recess 7 is horizontal and the vertical surface 11 is oriented in the vertical direction. The vertical distance h of the vertical surface 11 of the recess 7 is set to be the same as the cross-sectional height of the girder 6.

In FIG. 4, reference numeral 12 denotes a building body to which the roof panel 1 is attached, and H steel 13 as a beam member is arranged on the eaves side. Reference numeral 14 is a purlin made of a channel material having a U-shaped cross section, which is fixed along the flange of the H steel 13 and is arranged so that its cross sectional opening faces the eaves side. A bolt hole 16 corresponding to the bolt hole 9 of the girder member 6 is formed in the upper flange portion 15 of the purlin 14.

Reference numeral 17 denotes a ceiling plate made of ALC material or the like, which is installed on the H steel 13. A bundle 18 is erected at the center of the upper surface of the ceiling plate 13, and a purlin support member 19 is installed at the upper end of the bundle 18. Reference numeral 20 denotes a connecting metal fitting for connecting the purlin 5 and the purlin support member 19, which is nailed to the vertical side surface of the purlin support material 19 side so as to project upward, and is fitted between the coupling metal fittings 19 from above. The purlin 5 is fixed to the purlin support member 19 by bolting the purlin 5 with a horizontal through bolt 21.

The roof panel 1 having the above structure is hoisted by a crane or the like (not shown), and as shown in FIG. 4, the purlin 5 is placed on the purlin support 19 and the girder 6 is placed on the purlin 14. It is set on the building body 12 side so as to be touched. After that, the purlin 5 and the purlin receiving member 19 are connected to each other through the coupling fitting 20, and the girder member 6 and the purlin 14 are inserted with bolts 22 into their bolt holes 9 and 16, and the bolt 22 is tightened. It is firmly fixed by tightening with the glove 23.

At this time, according to the present embodiment, since the bolt hole 9 for fastening the bolt 22 to the purlin 14 side is provided in the girder material 6 in the vertical direction, the bolt 22 is provided as in the conventional case. There is no need for a worker to go into the ceiling to insert it, and only the worker on the eaves side can insert and tighten the bolt 22, which greatly reduces the construction time when installing the roof panel 1. be able to.

Further, in this embodiment, since the girder material 6 is attached to the roof panel 1 in advance in a factory or the like, and it is not necessary to provide the girder receiving material 29 as in the conventional case, the material cost of the roof panel 1 is reduced. There is also an advantage that it can be reduced.

[0017]

[Effect of the device]

 As described above, according to the present invention, it is possible to insert and tighten the bolt 22 into the bolt hole 9 by one worker from the eaves side, so that the work for mounting the roof panel 1 can be performed. The labor can be greatly reduced.
