Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof construction method and a roof panel hanging tool.

[0002]

2. Description of the Related Art Conventionally, a method of constructing a roof by installing a plurality of roof panels on an upper part of a living room structure has been performed.

As an example of such a method, Japanese Patent No. 285
JP-A No. 4715 (Japanese Unexamined Patent Publication No. Hei 4-269243) discloses an example. In this publication, the roof panel is lifted one by one from the cargo bed of the truck one by one in the living room structure.

[0004]

However, in the above-mentioned publication, since the roof panels are lifted one by one from the truck bed to the upper part of the living room structure, the reciprocating path of the roof panels is long, and the construction time is long. There was a problem of hanging.

Accordingly, an object of the present invention is to provide a roof construction method and a roof panel hanging device which can solve the above-mentioned problems and shorten the construction time by shortening the trajectory of the roof panel. It is in.

[0006]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a plurality of stacked roof panels are collectively lifted and installed at a fixed position of a lowermost roof panel. After that, it is characterized by the construction method of the roof which is installed at the fixed position in order from the upper roof panel.

According to the first aspect of the present invention, a plurality of stacked roof panels are lifted at a time and installed at a fixed position on the lowermost roof panel to fix the roof panels. By releasing and installing the roof panel at the fixed position in order from the upper roof panel, the trajectory of the roof panel is shortened, and the construction time can be shortened accordingly.

According to the second aspect of the invention, a substantially L-shaped locking portion in side view, which can lock the side and bottom portions of the roof panel and has a hook locking hole near the upper end, is provided. A connecting portion projecting downward from the stop portion and having a connecting hole that can be interconnected by a connecting member to a hook locking hole of a locking portion of another roof panel hanging device located below; It is characterized by a roof panel hanger equipped with:

According to the second aspect of the present invention, a plurality of roof panels whose side portions and bottom portion are locked by locking portions substantially L-shaped in side view are vertically stacked, and Between the connecting hole of the connecting portion projecting downward from the locking portion located at the bottom and the hook locking hole of the locking portion of another roof panel hanging device positioned below using the connecting member. By interconnecting, a plurality of roof panels can be fixed in a stacked state.

First Embodiment A first embodiment of the present invention will be described below with reference to the drawings.

1 to 7 show a first embodiment of the present invention.

In the first embodiment, FIGS. 1 and 2
As shown in FIG. 1, a substantially L-shaped locking member in side view having a vertical portion 5 capable of locking the side portions of the roof panels 1 to 4 and a horizontal portion 6 capable of locking the bottom portions of the roof panels 1 to 4. A roof panel hanger 8 having a part 7 is provided. Then, a hook locking hole 9 is formed near the upper end of the vertical portion 5 in the locking portion 7. Further, a plurality of screw holes 10 are formed in the horizontal portion 6 of the locking portion 7.

A vertical portion 11 protruding downward from a substantially middle portion of the horizontal portion 6 of the locking portion 7 and a horizontal portion 12 capable of pressing and holding the upper portions of the roof panels 2 to 4 located below. The roof panel hanging device 8 is provided with a substantially L-shaped connecting portion 13 having a side view. A connection hole 15 is formed in the vertical portion 11 of the connection portion 13 between the hook portion 9 and the hook engagement hole 9 of another engagement portion 7 located below, by a coupling member 14 such as a bolt. .

At the factory, a plurality of pieces (four pieces in FIG. 1) of which four portions near both end portions on both sides and the corresponding bottom portion are locked by locking portions 7 substantially L-shaped in side view. ) Are vertically stacked, and a connecting hole 15 of a connecting portion 13 protruding downward from the locking portion 7 positioned above and another locking portion 7 positioned below. The plurality of roof panels 1 to 4 are fixed in a stacked state by mutually connecting the hook locking holes 9 with the connecting members 14 such as bolts.

As shown in FIG. 3, a plurality of roof panels 1-4 fixed to each other in a stacked state are attached to a crane 16
The cargo is loaded on the loading platform of the truck 17 by using, for example, and transported to a construction site as shown in FIG. At this time, the hanging hook of the crane 17 is locked in the hook locking hole 9 of the locking portion 7 of the roof panel hanging tool 8 at the uppermost stage.

As shown in FIG. 5, a plurality of stacked roof panels 1 to 4 are collectively lifted by using a crane 18 or the like at a building site in the same manner as described above, and a roof truss 21 at an upper part of the living room structure 20 is lifted. At the bottom of the roof panel 1
4 and the temporary peg 2 is positioned at a position avoiding the roof panel hanger 8 of the lowermost roof panel 4 as shown in FIG.
At 2, it is temporarily fixed to the roof truss 21. In addition, roof truss 2
In the case of No. 1, since the strength is given in consideration of the snow load, even if the roof panels 1 to 4 are temporarily mounted, there is no problem.

Next, the fixing between the roof panels 1 to 4 is released by removing the connecting members 14 such as bolts, and FIG.
As shown in (1), the roof panels 1, 2, 3 in the upper stage are sequentially installed at fixed positions and fixed to the corresponding roof truss 21. In addition,
Roof panel hanging tools 8 that have become unnecessary due to fixation to the roof truss 21 are removed by pulling down from between the roof truss 21 and the roof panels 1-4.

As described above, after the plurality of stacked roof panels 1 to 4 are collectively lifted and set at the fixed position of the lowermost roof panel 1, the upper roof panels 1, 2 and 3 are sequentially set to the fixed positions. , The trajectories of the roof panels 1 to 4 are shortened, and the construction time can be shortened accordingly.

[0019]

As described above, according to the first aspect of the present invention, a plurality of stacked roof panels are lifted at a time and installed at a fixed position of the lowermost roof panel, and then the upper roof panel is installed. By installing the roof panel at a fixed position sequentially from the panel, the trajectory of the roof panel is shortened, and the construction time can be shortened accordingly.

According to the second aspect of the present invention, a plurality of roof panels whose side portions and bottom portion are locked by substantially L-shaped locking portions in side view are stacked one on top of the other, and from the locking portion located above. By interconnecting the connecting hole of the connecting portion projecting downward and the hook engaging hole of the engaging portion of another roof panel hanging device located below by using a connecting member, This can exert a practically useful effect that the roof panels can be fixed in a stacked state.
