Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an existing roof slope repairing method and an existing roof slope repair metal fitting, and using an existing roof, a new roof of various slopes can be easily mounted on the existing roof. It is designed to be thatched.

[0002]

2. Description of the Related Art Conventionally, as a conventional method for improving the slope of an existing roof of this type, when a roof with a new slope is to be roofed on the existing roof 10 as shown in FIG.
The talki (moya) 12 is sequentially fixed on the square bar 11 through a plurality of horns 12 having different lengths in order to obtain an appropriate gradient.
There is one in which the base plate 13 is fixedly mounted on the ‘′, and the roof is covered with a new appropriate roofing material on the base plate 13.

In addition, Japanese Patent Laid-Open No. Sho. As in JP-A 60-138169, a truss unit formed by attaching a lattice between an upper chord member and a lower chord member which are connected in a V shape in advance is placed on the roof to be repaired, and the V-shaped tip portion is directed toward the eaves side. There is also known a method of repairing an existing roof in which a plurality of parallel roof members are mounted and fixed in parallel with each other at intervals, and a new roof constituent material is roofed on these truss units.

[0004]

By the way, according to the former method in the above-mentioned prior art, in order to form a roof with a new slope on the existing roof 10, the above-mentioned timber 11 and tsuka 1 are used.
2. All the work of installing and installing the base plate 13 is done by carpenters in carpentry work, and the roofing work is done by a roofing contractor after these carpentry works. There was a problem that it became large.

In the latter case, the truss unit, which is formed by previously connecting the upper chord member and the lower chord member in a V shape with a required slope by a lattice, is transported to the site and is attached to the existing roof. There are problems such as large scale, complicated work, and large construction and work costs.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and as an existing roof slope repairing method, a first method in which a plurality of holes are fixedly installed on both sides at predetermined intervals so as to face each other. The U-shaped channel is fixed on the existing roof with the recess side facing upward, and a plurality of holes are fixed on both sides at a predetermined interval above the first U-shaped channel. The second U-shaped channels provided are overlapped with the recess side facing downward, the positions of the holes of both channels are appropriately selected, and a plurality of U-shaped channels are formed at both ends of these holes. It is characterized in that the slopes of the second U-shaped channel are changed by inserting and fixing the screw parts of the slope adjusting metal fittings.

As the existing roof slope repair metal fitting, a first U-shape is formed by fixing a plurality of holes facing each other at a predetermined interval on the existing roof with the recess side facing upward. No. 2 channel and a second U-shaped channel formed by stacking a plurality of holes facing each other at predetermined intervals above the first U-shaped channel with the recess side facing downward. And a plurality of U-shaped slope adjustment metal fittings with the screw parts engraved on both ends, and when modifying the existing roof slope, select the holes for both channels as appropriate and use the U-shape for these holes. The slopes of the second U-shaped channel are changed by inserting and fixing the respective screw portions of the slope adjusting metal fittings.

1 to 4 are views showing a preferred embodiment of an existing roof slope repairing method and an existing roof slope repairing metal fitting of the present invention. 1 to 3 show an existing roof slope repair metal fitting used in the existing roof slope repair method of the present invention.
2 is a perspective view showing a second U-shaped channel, and FIG. 3 is a U-shaped gradient adjusting metal fitting. FIG. 4 is a schematic diagram for explaining a method of repairing a roof with a new slope on the existing roof using the existing roof slope repair metal fitting of the present invention.

1 is both sides 1b of the recess 1a as shown in FIG.
A first U-shaped channel made of steel or the like having a plurality of holes 1c facing each other at a predetermined interval is provided, and a plurality of holes 2c are provided at both sides 2b of the recess 2a as shown in FIG. It is a second U-shaped channel made of steel material and the like facing each other. Reference numeral 3 denotes a plurality of U-shaped gradient adjusting metal fittings each having a threaded portion 3a formed at both ends. The first U-shaped channel 1, the second U-shaped channel 2 and the U-shaped slope adjustment metal fitting 3 constitute an existing roof slope repair metal fitting of the present invention.

Next, an existing roof slope repair method of the present invention will be described. First, the first U-shaped channel 1 in which a plurality of holes 1c are fixedly installed on both sides 1b at a predetermined interval is fixedly installed on the existing roof 4 with the concave portion 1a side facing upward. Above the U-shaped channel 1 of 1,
A second U-shaped channel 2 having a plurality of holes 2c fixed and fixed on both sides 2b at a predetermined interval is stacked so that the recess 2a side faces downward.
The positions of c and 2c are appropriately selected and these holes 1c and 2c are
By inserting the screw portions 3a of a plurality of U-shaped gradient adjustment metal fittings 3 respectively engraved at both ends into each of them and fixing them with a nut, the gradient of the second U-shaped channel 2 can be freely set. I am trying to change.

As described above, the roof is covered with a suitable roofing material on the second U-shaped channel 2 which is installed in parallel on the existing roof 4 by using the plurality of existing roof slope repair metal fittings. Because of this, the existing roof slope renovation work can be easily carried out only by the roofing contractor, and the economic burden is small.

Although not shown, at the tops of the pair of second U-shaped channels, these side plates are butted against each other and fixed by a connecting member to improve the appearance and further improve the strength. It is a thing.

[0013]

According to the existing roof slope rehabilitation method of the present invention, a plurality of holes are fixedly installed facing each other at predetermined intervals.
The U-shaped channel is fixedly installed on the existing roof with the recess side facing upward, and a plurality of holes are provided on both sides of the first U-shaped channel at predetermined intervals above the first U-shaped channel. A fixed second U-shaped channel is overlaid with the concave side facing downward, the positions of the holes of both channels are appropriately selected, and a plurality of U-shaped channels are formed at both ends of these holes. Since the screw portions of the metal-shaped gradient adjusting metal fittings are inserted and fixed respectively, the gradient of the second U-shaped channel can be changed. By using the existing roof slope repair metal fittings consisting of the second U-shaped channel and a plurality of U-shaped slope adjustment metal fittings, carpentry work is not required and only the roofing contractor is efficient. And can be easily installed in a short time It can have a high productivity, and there is an effect, such as even less economic burden.

Further, the existing roof slope repair metal fitting of the present invention is
A first U-shaped channel, which is fixedly installed on the existing roof with the recess side facing upward, and has a plurality of holes facing each other at predetermined intervals, and the first U-shaped channel. Second U-shaped channel formed by stacking a plurality of holes facing each other on both sides at a predetermined interval, and a plurality of holes in which screw portions are engraved at both ends, respectively. It is composed of U-shaped slope adjustment metal fittings, and when modifying the existing roof slope, select the holes of both channels appropriately and insert the screw parts of the U-shaped slope adjustment metal fittings into these holes respectively. Since the slope of the second U-shaped channel can be changed by being fixed, these metal fittings can be easily manufactured in advance in a factory and have a simple structure. There is no need, handling at the time of construction is easy, and cost is low. It has the effect of Runado.
