[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is suitably applied to the construction of a roof with a unitized roof panel 3 in which each component is shown in an exploded state as an example in FIG. The hut group 1 is constructed in advance. A plurality of unitized roof panels 3 are regularly suspended and fixed in a predetermined order on the main house 2 on the roof surface, and after which the wrapping 4
4 'is also suspended and installed. The unitized roof panel 3 is configured as a unit member that has been finished up to the roofing material 7 (metal tile) in addition to the rafters 5 and the baseboard 6 (see FIG. 2), and in the example of FIG. It is unitized in length.

FIG. 2 shows that both the eaves side and the ridge side of the roof panel 3 are suspended by crane wires 26 (or ropes, chains, etc .; the same applies hereinafter), and the roof surface of the hut set 1 is inclined. Is shown in a suspended state. An eaves hanging hardware 22 is used to suspend the roof panel 3 on the eaves side, and a position protruding long from the panel edge is hung so as not to damage the roofing material 7 made of a thin steel plate or the like. The ridge-side hanging hardware 29 is used for suspension on the ridge side, and the roofing material 7 and the field plate 6 also made of a thin steel plate or the like are hung so as not to be damaged. The eaves hanging hardware 22 and the ridge hanging hardware 29 are each fixed to the terminal of the wire 26 of the crane by the shackle 27, and can be repeatedly used in crane work.

In order to use the above-mentioned hanging hardware 22 and 29, a reinforcing lightweight steel such as a C-shaped steel used as the hanging metal fastener 20 is provided along the side surface of the rafter 5 of the roof panel 3. The rafter is attached to substantially the entire length or only to a necessary portion at a necessary length, and a hanging metal fitting member on the eaves side and the ridge side is formed. The reinforcing lightweight steel is a ridge hanging hardware 29.
In addition to the case where the required length is attached to the ridge section side where the roof is used as the hanging member locking member 20, the rafter itself of the roof panel is made of a member such as C-shaped steel, and the rafter itself is used as the hanging bracket. In some embodiments, it is used as a locking member. The hanging member locking member 20 is not limited to a C-shaped cross section, and may be used even if it is square. Further, members having other cross-sectional shapes can be used.

By the way, the eaves hanging hardware 2 shown in FIG.
2 is inserted into the groove of the eaves-side hanging member locking member 20, and the retaining projection 21 protruding from the distal end of the hanging-end metal hanging member 22 is fitted into the locking hole 23 of the eaves-side hanging hardware 22. Lock. Furthermore, the above-mentioned locked state is always safely maintained by the action of the leaf spring 24 raising the eaves hanging metal member 22. On the other hand, when the rope 19 fastened to the hole 18 at the tip of the eaves hanging part 22 is strongly pulled down from the ground side, the retaining projection 21 comes off the hooking hole 23, and the eaves hanging part 22 is further connected to the hanging fitting. It can be removed from the stop member 20.

The first aspect of the present invention covers the inventions of the second to fifth aspects. As an embodiment of the ridge side suspension structure of the roof panel according to the present invention, the side end of the ridge side suspension metal fitting locking member 20 of the roof panel 3 unitized as described above has a lower surface portion. , The cylindrical body 28 forming the suspension hole is substantially horizontal (by ridge) by means such as welding.
(FIGS. 2 and 3). On the other hand, it is fixed to the wire 26 of the crane,
A detachable ridge hanging hardware 29 is prepared on the ridge side of the ridge. As shown in FIG. 3, the ridge suspender 29 is formed of a long member having a groove-shaped cross section large enough to fit the suspending member retaining member 20, and an upper portion thereof is bolted to the shackle 27. And use it in a vertical position. The ridge suspension hardware 29 is connected to the hole of the cylindrical body 28 by a horizontal stopper pin 30 to perform a suspension operation. In addition, cylindrical body (or pin hole)
May be provided in a direction perpendicular to the web of the ridge hanging hardware 29. The stop pin 30 is in a state in which a spring plate 31 (or an elastic material such as a coil spring, etc .; the same applies hereafter) is always bulged to a diameter larger than the hole diameter of the cylindrical body 28 at the tip end for safety. is set up. As shown in FIG. 2, the ridge hanging metal fitting 29 has a contact metal 29a that comes into contact with only the outer end of the lightweight reinforcing steel member 20 having high hardness and rigidity when the roof panel 3 is hung, and is soft during the hanging operation. The construction is such that the base plate 6, the water stop plate 14, and the like are not damaged by the ridge hanging hardware 29. In addition to the case where the cylindrical body 28 is attached to the suspension fitting locking member 20 of this embodiment by welding or the like, a hole through which the stopper pin 30 directly penetrates may be provided in the suspension fitting locking member 20 itself. .

By the way, in suspending the roof panel 3, the ridge suspension hardware 29 located at the highest ridge of the roof is removed from the ground side by removing the locking pin 30, and the ridge suspension hardware 29 is removed from the roof. As a means for detaching from the panel, a tool for removing a locking pin shown in FIG. 4 is used. An operator fits the lower end of the ridge hook 29 on the upper end of a lightweight tube 32 that is easily reachable to the lower end of the ridge suspender 29 of the ridge by the worker holding it from the floor side of the hut assembly 1. Upward grooved metal fitting 3 capable of taking a reaction force
3 is attached. Further, an arm 34 protrudes laterally from the metal fitting 33, and a rope guide 35 is provided on the arm 34. When preparing the suspension of the roof panel 3 on the ground, a sufficiently long operation rope 36 (wire, chain, etc.) is attached to the base ring of the pin 30 connecting the lightweight lightweight section steel 20 for reinforcement and the ridge suspension hardware 29. And the same shall apply hereinafter). When the roof panel 3 is suspended in the hut set 1 and the ridge hanging hardware 29 is to be detached, a worker on the ground side lifts the pin removal tool shown in FIG. The rope 36 descending from the gap between the ridges is hung on the rope guide 35, and the bracket 33 is inserted into the lower end of the ridge hanging hardware 29 to sufficiently secure the reaction force, and then the rope 36 is pulled strongly. Then, it is possible to overcome the action of the retaining spring 31 and pull out the pin 30 by the pulling force of the rope 36 which is bent in the horizontal direction by passing through the rope guide 35 and forms a series of horizontal portions with the pin 30. As a result, the ridge hanging hardware 29 is detached from the reinforcing lightweight steel 20.

In short, the ridge hanging hardware 29 is attached to the wire 26 of the crane and can be used repeatedly, and is detachable from the roof panel 3. After the roof panel 3 is suspended and fixed on the hut set 1, it is a great feature that the worker does not need to climb the roof and can be detached from the roof panel 3 as an operation from the ground side. .

[0017]

According to the roof panel ridge suspension structure of the present invention, the roof panel has a structure in which all necessary related parts such as roofing material, water stoppage, drainage, etc. are unitized into one panel. Can be suspended without damaging any soft roofing material. Then, the ridge hanging hardware that has become useless after the hanging installation of the roof panel can be easily and reliably detached from the roof panel by a simple operation such as pulling a rope from the ground. Therefore,
It is completely unnecessary for a roof craftsman to climb and work on the roof when constructing the roof, which contributes to labor saving, improvement in work efficiency, and improvement in worker safety. Moreover, even if the suspension structure is implemented, there is no inconvenience that a post-treatment such as a rain break is required. Therefore, in this sense, the work efficiency is high, and it is possible to easily achieve the goal of completing the roof in one day. Close.
