Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof relining method.

[0002]

2. Description of the Related Art When changing the roof of an old building, remove roofing materials such as roof tiles, then remove the ground boards and rafters, and leave only the main building, and install new rafters on the main building. , Laying a field board on it and roofing it.

However, since most of the members constituting the existing roof are removed in this construction method, if rain or the like falls during the roofing work, rain will enter the interior of the building. Japanese inventor applied for a patent No. 1 in 1986
No. 11243 was filed as an application for an improved construction method for the thatching method.

In this construction method, roofing materials such as roof tiles of the existing roof are peeled off, and as shown in FIG. 5, a veneer board is laid on the existing base plate, waterproof paper is stuck on the plywood board, and rafters are placed on it. The roof was arranged by laying a field board on it. When arranging the rafters, they were nailed to an existing purlin. In this way, only roofing materials such as roof tiles are peeled off from the existing roof members, and a plywood board is laid on the existing baseboard and waterproof paper is applied, so it rained during the roofing work. Even so, the inside of the building can be rebuilt without leaking rain.

[0005]

However, according to this construction method, when a new rafter is installed, it penetrates through the existing field board and is nailed to the existing purlin. The existing rafters arranged above are often arranged at different intervals, and are not necessarily constant intervals. For this reason, when a new rafter is nailed, it is often nailed where there is a space between the existing field board and the existing purlin, and it is not possible to obtain a sufficient fixing force and a new rafter is used. Had a weak sticking force.

Further, when a new rafter is installed, the core bar is installed at the same position as the position where the new rafter is installed, so that accurate indexing must be performed. Since it is flexible, it is difficult to perform accurate indexing due to wrinkles, etc.Also, if the spacing between cores is changed due to design changes after laying a new base plate, the cores will be Since the installed position is not the position where the new rafter is installed, it is not possible to obtain a sufficient fixing force when fixing the core bar.

Further, as shown in FIG. 6, there is a case where an existing rafter has a wide interval and a new rafter is disposed at the center of the rafter interval. In this case, the existing rafter penetrates through the existing field board. Since there is a space between the existing baseboard and the existing mainboard when nailing the mainboard, the new weight of the rafters and the force to hit the nail are added to the existing baseboard, and the existing baseboard becomes uneven. Or, there was a risk of cracks or, in the worst case, cracks.

[0008] When a new rafter is arranged on an existing ground plate having a flat surface, the height of the rafter arranged is not constant, and a new ground plate laid on the rafter is also the same. There is a risk that the roof will become uneven and in this case the roof that has been changed will also become uneven and thatched.
The aesthetics of the re-roofed roof was bad.

In view of the above problems, the present invention can more firmly and securely fix members such as a new purlin to be installed, and can be applied to existing field boards even if the interval between existing rafters is not constant. It is an object of the present invention to provide a roof-roofing method that can replace the roof without causing unevenness or cracks, and can solve the problems that have occurred due to the existing unevenness of the baseboard. And

[0010]

Therefore, according to the present invention, a new purlin is placed on an existing floorboard, and a new plainboard is laid on the purlin parallel to the flow direction of the roof. The cores are arranged on the main plate at predetermined intervals.

[0011]

[Operation] The new purlin placed on the existing field board is fixed to the existing rafter via the existing field board, and the core tree placed on the new field board is fixed to the new purlin via the new field board. Therefore, the fixation between these members can be made stronger and more reliable. Also, even when the new purlin is placed on the existing floorboard, the new purlin is placed perpendicular to the flow direction of the roof and is fixed to the existing rafters through the existing floorboard.
Even if the weight of the new purlin itself or the fixing force at the time of fixing is applied to the existing field board, the existing field board will not be roughened.

[0012]

Embodiments of the present invention will now be described with reference to the drawings. It is needless to say that the present invention is not limited to the embodiments described below and can be variously implemented without departing from the scope of the claims.

FIG. 1 is a schematic cross-sectional view showing a state in which the roof has been refurbished, and FIG. 2 shows an existing floorboard. FIG. 3 is a schematic perspective view showing a state in which a new purlin is arranged, FIG. 3 is a schematic perspective view showing a state in which a new field board is laid on the new purlin, and FIG. 4 is a schematic showing a state in which core wood is arranged in the new field board. It is a perspective view. 1 is a new purlin, 2 is a new floorboard, 3 is a core bar, 4 is a fastener such as a nail, 5 is a fastener such as a nail, 11 is an existing purlin, 12
Is an existing rafter, and 13 is an existing field board.

In the roof relining method, as shown in FIG. 1, a new purlin 1 is arranged on the existing floorboard 13 so as to be perpendicular to the flow direction of the roof, and the roof flow direction is arranged on the new purlin 1. The new base plate 2 is laid so as to be parallel to the base plate, and the core 3 is arranged on the new base plate 2.

The new purlins 1 are arranged on the existing field board 13 at substantially equal intervals as shown in FIG. The new purlin 1 can be fixed to the existing rafter 12 through the existing field board 13 by a fastener 4 such as a nail.

The new field board 2 is laid on the new purlin 1 so as to be parallel to the flow direction of the roof as shown in FIG. The sticking of this new field board 2 on the new purlin 1 is
Although not shown in the drawing, it is fixed to a portion that intersects with and is in contact with the new purlin 1 by a fastener such as a nail.

The core bars 3 are arranged on the new field board 2 at predetermined intervals as shown in FIGS.
The core wood 3 can be fixed to the new field board 2 via the new field board 2 by the fasteners 5 such as nails. Further, the core wood 3 is composed of a rootstock 3a, a rootstock 3b, and a half-round rootstock 3c as shown in the figure. Fasten, install the rootstock 3b on the rootstock 3a, and fasten it with the fasteners 5a such as nails, and further install the half-round rootstock 3c on the rootstock 3b to fasten the nails and the like. It is fixed on the new field board 2 with the tool 5. In addition, although the ventilation holes are provided between the rootstocks 3b,
Not limited to this, the vent may not necessarily be provided.

Next, the procedure of the roof changing method will be described. First, remove roofing materials such as roof tiles from the existing roof, and
The new purlins 1 are arranged on the above at substantially equal intervals. Next, a new field board 2 is laid on the new purlin 1 so as to be parallel to the flow direction of the roof. Then, the new baseboard 2 is accurately indexed, the cores 3 are arranged at the indexed intervals, and roofing materials such as tiles are roofed by a known method.

Since it may rain during the construction, after installing the new purlin 1 on the existing floorboard 13, or on the new floorboard 2, the base of the core 3 can be installed. After fixing the tree 3a, waterproof treatment such as sticking waterproof paper (not shown) is performed.

The roofing replacement method of the present invention is the same as the existing floorboard 1
3 is fixed to the existing rafter 12 through the existing field board 13 and the core 3 is disposed on the new field board 2 to the new purlin 1 through the new field board 2. Because of the fixation, the fixation between these members becomes stronger and the new purlin 1 is arranged on the existing field board 13 so that the height is constant. The ground plate 2 will not be rough, and the aesthetic appearance of the roof that has been changed will be good.

When arranging the new purlins 1, it is sufficient to dispose them at right angles to the roof flow direction and at substantially equal intervals without arranging the fixing positions accurately.
It is also possible to arrange the new purlin 1 while peeling off roofing materials such as roof tiles of the existing roof at the time of construction. In this case, it is possible to shorten the working time, and thus to shorten the cost and the overall construction period. Become.

When it is determined that the existing roof plate 13 cannot be used due to cracking or corrosion when the roof material such as roof tiles is peeled off, the existing roof plate 13 is removed.
Peel off and lay a new field board. In this case, it may rain when laying the ground plate, so
Make sure that the waterproof sheet is stretched.

Further, since the roof that has been used for a long period of time is often uneven, when the new purlin 1 is arranged on the existing floorboard 13, a gap may occur between them. is there. In this case, the new main building 1 and the existing floorboard 1
While sandwiching a piece of wood, etc. with 3, and fixing the unevenness, fix the new purlin 1 and the piece of wood, etc. on the existing field board 13 with the fasteners 4, and then change the roof in the same procedure as described above. Go.

[0024]

[Effect] As described above, in the roofing replacement method according to the present invention, the new purlin to be placed on the existing floorboard is fixed to the existing rafters through the existing floorboard, and is placed on the new floorboard. Since the core wood is fixed to the new purlin via the new field board, the fixation between these members can be made firmer and more reliable.

Further, since the new field board can be indexed after being laid, it is possible to dispose the cores accurately and at a predetermined interval, and when the cores are fixed, the new field board is fixed. Since it will be fixed to the new purlin through the, even if the spacing of the core bars is changed due to design changes after laying the new ground board, the core bars should be firmly and securely fixed at the changed intervals. You can

Further, even when the new purlin is arranged on the existing floorboard, the new purlin is arranged perpendicularly to the flow direction of the roof and fixed to the existing rafters through the existing floorboard. Since the new purlin is installed on the existing floorboard so that the height is constant, each member newly built on it, for example, the new floorboard, will not be damaged, and the aesthetics of the roof that was changed Will also be good.
