DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of installing a roof panel for laying rafters and a base plate on a house whose building has been completed, and a roof panel used for the method.

[0002]

2. Description of the Related Art For example, in a wooden building that has been completed in a conventional building, a scaffold is constructed, and a worker such as a carpenter himself nails a plurality of rafters onto the top of the purlin, girder or eaves girder. He nailed the rafters as if laying a field board. This construction naturally requires specialized skills and is also an operation at a high place, so it involves dangers, and therefore has to be performed by a professional worker such as a carpenter.

[0003]

In recent years, young people have been remarkably separated from physical labor, and the number of field workers specialized in civil engineering and construction has decreased. For this reason, it has become difficult to carry out the above-mentioned work of attaching the rafters and the baseboards by relying on a specialized worker such as a carpenter as in the past. In addition, when a skilled worker is used, there is a problem that the construction cost is increased due to the increased labor unit price. However, generally, it has been desired to reduce the construction cost and further shorten the construction period, and in such a situation, it has become difficult to manually assemble the members individually.

[0004] Therefore, first of all, to supplement the decrease in the number of specialized workers, work at high altitudes that involves danger is improved,
At the same time, in consideration of reducing the construction cost and shortening the construction period, the review of the installation work of the rafters and the baseboard was examined from the viewpoint of the materials used and the construction method.

[0005]

As a result, what has been developed is that a plurality of rafters 1 each having a length from the ridge to the eaves are arranged, and a field board 2 having a predetermined width is placed on the rafters 1 on the ridge side. Ridge 1 on the ridge side excluding the baseboard 2 except for the floor board 2
Scoop groove 11 hooked on 31, nail hole 12 nailed on purlin 3
And a hook receiver 13 for receiving a hook of a crane, and a roof panel 6 having a roof plate 6 attached between the rafters 1 on the eaves side and the base plate 2 and the eaves girder 4 between the rafters 1 on the eaves side is manufactured in advance at a factory. 6 is lifted by a crane on the hook receiver 13 at the construction site, and the protruding portion of the purlin 3 of the house building which has finished building.
31 is placed from the ridge to the eaves so as to catch the scooping groove 11 on the rafter 1 on the ridge side except for the base plate 2, and the rafters 1 each having the same shape as the existing base plate 2 on the rafter 1 on the ridge side. The roof panel 6 is nailed to the purlin 3 by nailing the nail hole 12 and one end of the bent connecting metal fitting 7 is connected to the side of the spar 8, and then the other end of the connecting metal fitting 7 is attached to the rafter of the roof panel 6. 1 is a method for installing a roof panel.

A roof panel 6 suitable for this construction method
A plurality of rafters 1 each having a length from the ridge to the eaves are arranged, and a baseboard 2 having a predetermined width is laid on the rafters 1 except for one on the ridge side. Rafter 1 and ridge 3
Scoop groove 11 hooked on 31, nail hole 12 nailed on purlin 3
And a hook receiver 13 for receiving a hook of a crane, and a roof panel in which a face plate 5 which is in contact with a base plate 2 and an eaves girder 4 is mounted between rafters 1 on the eaves side.

[0007] In the method of mounting the roof panel, a bent fitting 7 for joining the rafter 1 and the girder 8 is used.
It is preferable that the bending angle of the joining metal fitting 7 is wider than the included angle on the ridge side formed by the lower surface of the rafter 1 and the side surface of the spar 8. The connection between the connection fitting 7 and the rafter 1 or the spar 8 may be made by wood screws instead of nailing.

[0008]

According to the roof panel mounting method of the present invention, a roof panel 6 manufactured in a factory is mounted at a building site. The roof panel 6 is a sheet in which the baseboard 2 is laid in advance on the rafter 1, and thereby, the rafter 1
In addition, the installation work of the base plate 2 is omitted, and the construction work is simplified only by placing and fixing the roof panel 6.

The scooping groove 11 provided in the rafter 1 can be hooked on the convex portion 31 of the purlin 3, thereby simplifying the positioning of the roof panel 6 in mounting. Hook support 13 provided on rafter 1
Allows the lifting of the heavy roof panel 6 by a power machine such as a crane. The nail holes 12 formed in the rafter 1 prevent the rafter 1 from cracking when the base plate 2 and the rafter 1 are nailed to the purlin 3 for fixing the roof panel 6. Since the face plate 5 is attached to the roof panel 6 in advance, the risky work of mounting the face plate at a high place is eliminated, and the construction cost and construction time are reduced.

[0010] The connecting bracket 7 to be connected to the side of the spar 8 and the rafter 1 is wider than the narrow angle on the ridge side formed by the spar 8 and the rafter 1, so that the fitting surfaces 71 and 72 are the spar 8 or the spar. When the rafters 1 are joined to each other in a state of being closely attached to each other, the girder 8 and the rafters 1 can be joined together in a state where the rafters 1 are attracted in the direction of the girder 8. Thereby, the installed roof panel 6
To the girder 8 or the eaves girder 4 in a crimped state without rattling,
Stabilize.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a roof panel mounting method according to the present invention; FIG. 1 is a partially cutaway perspective view showing a state in which a roof panel is placed from a ridge to an eave, FIG. 2 is a side view thereof, and FIG. 3 is an area A in FIG.
FIG. 4 is an enlarged view of the part, and FIG.
FIG. 5 is an enlarged view of a portion B in the middle, and FIG. 5 is a partially cutaway side view of the portion C in FIG. 2 near a fitting for joining the rafter and the girder of the roof panel.

First, a roof panel 6 previously manufactured in a factory.
The structure of each part will be described in order while showing the relationship with the purlin 3, the eaves girder 4 or the girder 8. As can be seen in FIG. 1, the roof panel 6 is a rafter 1 having a cross section of about 40 to 60 mm on a side and having a length of 6 m or more, and the rafter 1 is about 1 m in length.
5 pieces are arranged at equal intervals within the width of
A base plate 2 of about mm, length of about 1 m and width of about 20 to 30 cm is stretched so as to cover all except one roof panel 6 on the ridge side. The roof panel 6 has a size of about 1 m in width and 6 m or more in length. Although the length of the roof panel 6 is free, adding the roof panel 6 has a problem in strength. Therefore, a roof panel 6 having a length from the ridge to the eaves is prepared, and one roof panel 6 is used. Be able to hang from the ridge to the eaves. The rafters and the ground boards may be used as they are made as needed.

As can be seen in FIG. 1, FIG. 2 and FIG. 3, the roof panel 6 has a depth of about 30 to 40 mm from the upper end so that the ridge side of the rafter 1 can be hung on the ridge 3. Sa15
A lug groove 11 of about mm is provided, and a bolt is provided on both sides as a hook receiver 13 for receiving a hook of a crane at a position about 60 mm from the upper end of the rafter 1 and at a position approximately halfway between the upper surface and the lower surface of the rafter 1. Has been established. Since one of the baseboards 2 attached to the rafters 1 is excluded from the ridge side, the crane can catch the bolts serving as the hook supports 13 from the upper surface of the roof panel 6 and lift the entire roof panel 6. At the upper end of the rafter 1, a nail hole 12 for nailing the rafter 1 to the purlin 3 is penetrated from the upper surface to the lower surface.

As can be seen from FIG. 1 or FIG. 2 and FIG. 4, the roof panel 6 is provided with a base plate 2 and a facing door plate 5 which is in contact with the eaves girder 4 on the eaves girder 4 side of the rafter 1. A pair of fitting grooves 51 are provided in each side surface and fitted, and in some cases, the face door plate 5 is nailed to the rafter 1 from the ridge side. The purpose of this face plate 5 is to prevent small animals such as rats and pigeons, dust, dust and the like from entering the attic. .

As can be seen in FIGS. 2 and 5, the roof panel 6 is made of a metal fitting 7 which is bent at a wider angle than the narrow angle on the ridge side formed by the rafter 1 and the girder 8, and Combine with digit 8. First, the metal fitting 7 is nailed by bringing the metal fitting surface 71 into close contact with the spar 8. At this time, the metal fitting surface 72 of the joining metal fitting 7 with the rafter 1 is so arranged that only its tip abuts on the lower surface of the rafter 1. Next, when a wood screw 73 is screwed in from the metal fitting surface 72 to the lower surface of the rafter 1, the metal fitting surface 72 and the rafter 1
Is narrowed, and the rafter 1 is joined by the elasticity of the joining fitting 7 in a crimped state in which the rafter 1 is pulled in the joining fitting 7, that is, in the direction of the spar 8. By using a plurality of such fittings 7 uniformly and entirely on the roof panel 6, the rafter 1 is joined to the girder 8 or the eaves girder 4 over the entire area of the roof panel 6, and the roof panel 6 can be stably mounted. In addition, the joint fitting 7
The connection with the spar 8 is preferably nailed because of the simplicity of the work, and the connection with the rafter 1 of the connection fitting 7 is preferably performed slowly while forming a crimped state.

The installation of the roof panel 6 is performed as follows. FIG. 6 shows this construction procedure in each stage of (a) placing a roof panel, (b) attaching a roof board at the upper end of the roof panel and fixing it to a purlin, and (c) joining a rafter and a girder.
It is the side view represented in order of (b) and (c). The roof panel 6
According to a predetermined standard, a large quantity is used in a factory. By doing so, the roof panel 6
Can lower the unit price. The roof panel 6 thus prepared may be transported by a required number of trucks or the like to the building site of a house whose building has been completed. On the other hand, on the completed house, the protrusion that locks the hiccup groove 11 of the roof panel 6
31 is provided symmetrically on the purlin 3 upper surface. A convex portion 31 may be provided partially on the upper surface of the purlin 3 in correspondence with the scooping groove 11, but this is inefficient, so it is preferable that the convex portion 31 be a convex streak having the same cross section.

As shown in FIG. 6 (a), the roof panel 6 is lifted by a crane at the hook receiver 13, is placed from the ridge to the eave, and is laid in order from the end. In this state, the roof panel 6 is in a state where the hiking groove 11 is merely hooked on the convex portion 31 of the purlin 3. Therefore, in order to fix the roof panel 6 in this state so that it does not fall, a base plate 21 is attached to the ridge side of the panel, and the rafter 1 is inserted through the nail hole 12 as shown in FIG. Nail to 3. At this time, the floor board 21 to be stuck together with the field board 22 at the symmetrical position closes the upper part of the purlin 3 or is covered with another member so that there is no gap on the roof top.

Next, in order to fix the entire roof panel 6 while making contact with the spar 8, first, as shown in FIG. The rafter 1 of the roof panel 6 and the joining metal fitting 7 are joined by a wood screw 73. It is also conceivable that the joining fitting 7 is attached to each girder 8 or a predetermined girder 8 in advance before the roof panel 6 is placed, and only the joining with the rafter is performed at this stage. In consideration of the purpose of fixing the roof panel 6 in the crimped state, which is the purpose of the joint fitting 7, and the workability, it is preferable to collectively attach and combine the roof panel 6 at the final stage of construction. This is because, if the fittings are attached in advance, there is a possibility that a positional deviation or a partial variation may occur in the crimping state of the roof panel 6 by the respective fittings, which is not preferable.

[0019]

According to the roof panel mounting method of the present invention, the work of mounting rafters, floor boards and the like in a house after ascending is significantly simplified and simplified, and the labor required for the work can be reduced and the time can be reduced. it can. Above all, almost uniform finish can be expected irrespective of the skill level of the workers, so it can be said that this is a very useful construction method at present when the number of specialized workers is decreasing.

On the other hand, with regard to the roof panel used in this construction method, it is possible to reduce the cost by providing a standardized product having a predetermined size to provide general versatility and at the same time mass-producing it in a factory or the like. it can. In this way, even if a large amount of stock is prepared, it can be efficiently distributed to each construction site, and the construction period of the entire construction work can be shortened. Further, since there is no need for high-risk work including mounting of the face plate at a high place, the safety of the worker is also improved.

Further, regarding each part of the roof panel, the entire roof panel can be easily and stably fixed by using the connecting metal, so that the subsequent work and the safety after the completion of the house are extremely high. This fitting can also be used when simply attaching a rafter to a girder. Further, since the face panel is automatically attached by attaching the roof panel, it is convenient and has a good appearance after completion.
