The present invention relates to a roof eave repair structure having a dovetail part that can be made simpler and cheaper.

[Conventional technology and its problems]

Conventionally, roofs with dovetail hooks have been constructed using roof boards, dovetail hooks, dovetail hooks, etc., and are popular in the Tohoku and Hokkaido regions because they require fewer parts, have a simple structure, and can be made at low cost. Even today, the roof is being actively constructed. However, the dovetail part is generally quite small, and the dovetail part is difficult to attach with a simple cap material at the eave side position, and even if it is attached, it easily comes off. Currently, it is being crushed with a hammer, etc. This had disadvantages, such as poor appearance and reduced product value by half, and rainwater entering through cracks when crushed.

[Means to solve the problem]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor has developed the present invention by placing and fixing dovetail hangers on the base material such as roofing boards or heat insulation boards, In a roof having a dovetailed part formed by dovetailing the protruding strips of the roof board on which the protruding stripes are formed on the dovetailed ropes, the roof has a dovetailed part formed as a dovetailed part. The main surface portion of the dovetail eave front door, which has a bent piece with a flat U-shaped cross section with a closed front surface formed on the lower side of the main surface thereof, is attached within the eave tip of the dovetailed part, and the bent piece By adopting a roof eaves repair structure having a dovetail part clamped and fixed within the bent edge of the tip of the bottom main plate of the roof board, the watertightness (rain protection) of the dovetail part is improved, and The eaves of the dovetail area were repaired to improve the appearance.
Furthermore, the structure can be made simple and inexpensive, and the above-mentioned problems have been solved.

Alternatively, a tile rod may be formed by the hanger 2 which has a U-shaped cross section (not shown) and the cap material and the rising portion of the end of the roof board 1, or a tile rod may be formed into an inverted T-shape. If the joint A ₂ is
The invention is not limited to the embodiments shown in the drawings.

B is a dovetail eave front door, which is bent at approximately right angles as side pieces on the top and both sides of the main surface 7 in an inverted T-shape or one-shape shape (in this way, the side pieces are bent on the main surface 7). The formed part is also referred to as the "principal surface 7 portion"), and on the lower side of this main surface 7, the front side (with the eaves side as a reference) is closed and a bent piece 8 having a flat U-shaped cross section is integrated. The inside of this bent piece 8 is provided with an insertion part 9.
It is formed as.

Reference numeral 10 denotes a fascia material for the eaves of the roof A, and a long arabesque material 11 made of metal and having a deformed gate shape in cross section is attached to the fascia material 10.

The insertion part 9 of the dovetailed eave front door B is inserted into the tip side of the arabesque material 11, and its main surface 7 is inserted and fixed appropriately into the eave tip of the dovetailed part _A1 of the roof A,
Then, the _dovetailed eave front door B
The bent piece 8 is clamped and fixed, and the dovetail eave front door B is attached in a watertight manner. In this case, the end of the dovetail portion _A1 to which the dovetail eave front door B is attached may be cut off as appropriate, as shown in FIG.

[Effect of idea]

In the present invention, the dovetail hanger 3 is placed and fixed on the base material 6 such as a field board or a heat insulation board, and the bottom main board 1a
The bulging strip 1b of the roof plate 1, which has the bulging strip 1b formed in the middle thereof, is dovetailed and joined to the dovetail hanging rope 3 to form the dovetailed portion _A1.
In a roof A having a dovetailed part _A1 , side pieces are formed on the upper side and both sides of the main surface 7, and on the lower side of the main surface 7, a bent piece with a flat U-shaped cross section with a closed front is formed. The 7 parts of the main surface of the dovetailed eave front door B formed with the dovetailed eaves 8 are installed within the eave tip of the dovetailed part _A1 , and the bent piece 8 is held within the bent edge of the tip of the bottom main plate 1a of the roof board 1. By adopting a roof eave repair structure with a fixed dovetail part, firstly, the watertightness (rainproofing) of the eave part of the dovetail part _A1 can be improved;
Second, it has a simple configuration and can be constructed at a relatively low cost.
Thirdly, the eaves at the dovetail portion _A1 can be repaired in an orderly manner, resulting in an extremely favorable appearance.

To explain these effects in detail, first, in the present invention, side pieces are formed above and on both sides of the main surface 7, and a bent piece 8 with a flat U-shaped cross section with a closed front is formed below the main surface 7. The 7 parts of the main surface of the dovetailed eave front door B that has been formed are attached within the eave tip of the dovetailed part _A1 , and the bent piece 8 is clamped and fixed within the bent edge of the tip of the bottom main plate 1a of the roof board 1. In particular, the rain protection (watertightness) at the tips of the eaves can be improved. In other words, the height of the dovetail part _A1 is generally small (about a few centimeters), so it is extremely difficult to install the dovetail eave front door.
Moreover, because it is easy to come off, conventionally, the dovetail part A ₁
At the eave side position, it was crushed with a hammer etc.
This had drawbacks such as rainwater infiltrating through cracks when crushed, but in this invention, even if it is small, the dovetailed eaves side door B is installed to make it watertight, so it can be made watertight. It is possible to provide an eaves repair structure that does not cause cracks and is extremely watertight (rainproof).

Furthermore, the dovetail eave front door B has a bent piece 8 with a flat U-shaped cross section with a closed front on the lower side of the main surface 7, and furthermore, the main surface 7 of the dovetail eave front door is dovetailed. By attaching it to the tip of the eaves of section A ₁ and clamping and fixing the bent piece 8 within the bent edge of the tip of the bottom main plate 1a of the roof board 1, the eaves tip is particularly useful in areas with heavy snowfall, etc. It is possible to eliminate the inconvenience that the dovetail eave front door B is extremely likely to come off due to falling.

Also, the dovetail part A ₁ has a dovetail eave front door B at the tip of the eaves.
It has the advantage of being easy to configure and relatively inexpensive to install.

Furthermore, in the past, the dovetailed part was crushed with a hammer etc., which had disadvantages such as poor appearance and halved product value, but in the present invention, the dovetailed eave front door B is It is attached to the tip of the _A1 eaves, and this eave has an extremely neat finish, which is completely different from the conventional eaves with dovetails, giving it an excellent architectural aesthetic.
