Abstract

PURPOSE:To lift a roof panel to the roof portion of a building with safety and certainty in such a manner as to prevent the panel from being broken. CONSTITUTION:A ridge-side cross core member 111 and an eaves-side cross core member 112 are disposed and longitudinal core members 121-125 are disposed between the ridge-side cross core member and the eaves-side cross core member and hook through holes 113 are formed through the respective side portions of the ridge-side cross core member 11 and the eaves-side cross core member 112 and hooks pass through the hook through holes 113, and a roof panel is formed which is lifted to the roof portion of a building by a lifting means via the hooks. Reinforcing members 140 for resisting outward bending moment which is exerted on the cross core members 111,112 when the roof is lifted are mounted on the respective junction corner portions of the cross core members 111,112 to the longitudinal core members 121-125.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to roof panels which are carried by hooks onto the roof of a building.

0002

2. Description of the Related Art Recently, unit-type roof panels that constitute the roof of a building are known. This type of roof panel is typically hung onto the roof of a building using a crane or the like.

0003

However, there is a problem in that it is difficult to lift the roof panel safely and reliably without damaging the roof panel. This invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a roof panel that can be lifted safely and reliably without breaking.

0004

[Means for Solving the Problems] In order to solve the above-mentioned problems, the roof panel according to the present invention is provided with a ridge side horizontal core material and an eave side horizontal core material, the ridge side horizontal core material and the eave side horizontal core material. A vertical core material is disposed between the core material, hook through holes are formed in the sides of the ridge side horizontal core material and the eave side horizontal core material, and the hooks are passed through the hook through holes, A roof panel that is hoisted onto a roof portion of a building by a hoisting means via the hook, wherein an outward facing part is provided at a joint corner of the horizontal core material and the vertical core material to hang on the horizontal core material during the lifting. The structure is such that a reinforcing member is installed to withstand the bending moment.

[0005]

[Operation] By inserting hooks into the hook holes of the ridge side horizontal core material and the eave side horizontal core material, and lifting it up with a crane etc. through the hooks, it can be safely and reliably placed on the roof of the building. . Even if an outward bending moment is generated on the ridge-side horizontal core material and the eave-side horizontal core material due to the lifting when they are lifted by the hooks, these horizontal core materials are reinforced by the reinforcing members, so the bending moment The horizontal core material is not separated from the joint of the vertical core material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 4 show an embodiment of a roof panel 100 according to the present invention. Of these, FIG. 1 is a broken perspective view of the roof panel 100, FIG. 2 is a partial perspective view of the roof frame frame 130, FIG. 3 is a perspective view of the reinforcing member 140, and FIG. 4 is a state in which the roof panel 100 is suspended by a crane or the like. FIG. The roof panel 100 according to this embodiment includes horizontal core members 111, 112 on the ridge side and eave side, and
A roofing material 135 and the like is attached to a frame 130 made up of vertical core members 121, 122, etc. arranged vertically therebetween.

To explain in more detail, the ridge side horizontal core material 1
11 and the eave side horizontal core material 112 are arranged parallel to each other, for example. The vertical core members 121, 122, .
, the ridge side horizontal core material 111 and the eave side horizontal core material 11 at both ends of the
2 are attached with nails or the like.

Roof frame frame 130 constructed in this way
The roofing material 135 is attached above. Hook through holes 113 are formed at left and right positions on the sides of the ridge side horizontal core material 111 and the eave side horizontal core material 112, respectively. Then, the horizontal core members 111 and 112 and the vertical core member 1
As shown in FIGS. 1 and 2, reinforcing members 140 are attached to each joint corner with screws 22 and 124 using screws or the like.

As shown in FIG. 4, this reinforcing material 140 has a hook 150 passed through the hook passage hole 113 of the ridge side horizontal core material 111 and the eave side horizontal core material 112, and is connected to a crane or the like through the hook 150. Roof panel 100 by lifting means
When the horizontal core members 111, 112
Due to the outward bending moment applied to the vertical core 121
This prevents it from being peeled off from the joint with ~125. This reinforcing member 140 is made of, for example, an L-shaped iron piece shown in FIG. 3, and screw holes 141 are provided in each side plate portion 143, 144 of the reinforcing member 140.

The reinforcing member 140 is constructed as described above, and each of its side plate portions 143, 144 is connected to the horizontal core member 112 (1).
11) and the vertical core material 122 (124), respectively, screw 1.
45 through the screw hole 141.

As described above, the roof panel 130 according to this embodiment has the hook through holes 141 formed in the sides of the ridge side horizontal core material 111 and the eave side horizontal core material 112 of the roof panel 100, and Horizontal core materials 111, 112 and the vertical core material 1
Since the reinforcing member 140 is attached to the joint corner with the hooks 22 and 124, the hook 15 is inserted into the hook passage hole 141.
If it is hoisted by a crane through the 0, it can be safely and securely placed on the roof of a building. Then, when the hook 150 is used to lift the ridge side horizontal core material 11
Even if an outward bending moment (a bending moment in the direction in which the lower ends of the horizontal core members 111, 112 bend outward) is generated in the horizontal core members 111 and 112 due to their lifting, the horizontal core members 111 and 112 Since the horizontal core members 111, 1 are reinforced by the bending moment,
12 will not be peeled off from the joints with the vertical core members 121 to 125.

Note that the ridge side horizontal core material 111 and the eave side horizontal core material 11
The position and number of the second hook through holes 113 may be freely changed in design. Further, the attachment position, attachment location, shape, etc. of the reinforcing member 140 may be freely changed in design as necessary. Furthermore, the shape of the hook 150 is similar to that of the hook through hole 113.
Any shape may be used as long as the roof panel 100 can be hung through the hook 150 therein. The numbers of the horizontal core members 111, 112 and the vertical core members 121 to 125 are not limited to those described above.

[0013]

Effects of the Invention As described above, the roof panel of the present invention has hook holes formed in the sides of the ridge side horizontal core material and the eave side horizontal core material of the roof panel, and the hooks pass through these hook holes. Since the device is lifted onto the roof of the building by means of a lifting means via the hook, it can be safely and reliably placed on the roof of the building. In addition, even if an outward bending moment is generated in the horizontal core material when it is lifted by the hook, the bending moment will be avoided because reinforcing members are attached to the joint corners of the horizontal core material and the vertical core material. The horizontal core material will not be destroyed.
