〔Effect of the invention〕

First, in the invention recited in claim 1, in the downward valley (a) of the horizontal roof plate which is constructed by engaging the lower part 9 and the upper part 10 of the horizontal roof board A, , this descending valley (
A flat U-shaped valley gutter material 4 is attached between both supporting members 2°2 installed along the line A), and the drooping edge 7b of the arabesque material 7 consisting of a horizontal portion 7a and a drooping edge 7b is attached to the valley gutter material 4. The arabesque material 7 is fixed to both supporting members 2, 2 at the downward valley (A) part, respectively, so that the arabesque material 7 is located on the bottom part 4a of the downward valley (A). The ends A and A were cut at an appropriate angle in plane, and this end was folded into the horizontal parts 7a, 7a of the arabesque materials 7, 7 to form a valley repair structure in a horizontal roof. As a result, firstly, the watertightness (watertightness) is particularly good, and secondly, there is a strong downhill valley (a).
It is possible to repair the parts, and thirdly, it is possible to cope well with the thermal expansion and contraction of the valley gutter material 4 and the thermal expansion and contraction of the roof board A for horizontal roofing.

To explain these effects in detail, the drooping edge 7b of the arabesque material 7 is placed on the bottom part 4a of the valley gutter material 4, and the arabesque material 7 is descended to both supporting materials 2.2 at the valley (a). Because they are fixed together, even if rainwater intrudes into the gutter material 4, the hanging edge 7b of the arabesque material 7 acts as a dam, and the rising part 4b, bottom 4a, and drooping edge 7b of the gutter material 4 are A void is formed, and the capillary phenomenon does not occur, allowing rainwater to infiltrate into both sides of the gutter material 4. As a result, the rainwater that has flowed down to the downward valley (a) of the horizontal cover roof is Rainwater flows down the bottom 4a of the gutter material 4 to the outside, and rainwater can be reliably blocked from entering into the interior from both sides of the gutter material 4, resulting in extremely good watertightness.

In addition, the horizontal roof board A facing the downward valley (A).

9 end phase "i2・'. Target 1" angle """ cut etc. L7.
.

This end was fixed to both supporting members 2.2 at the downward valley (a). At the tips of the horizontal parts 7a and 7a of the arabesque material 7.7
□Due to the folding process, the downward valley (
b) The ends of the horizontal roofing sheets A and A are fixed to the supporting material 2 via the arabesque material 7, and can be fixed relatively firmly and can withstand wind pressure sufficiently. There are advantages that can be achieved.

In addition, even if the horizontal roofing board A expands and contracts due to heat in the longitudinal direction,
The end portion in the longitudinal direction is simply folded at the tip of the horizontal portion 7a of the arabesque material 7, and is not fixed, so that it can absorb the thermal expansion and contraction.

Further, even if the valley gutter material 4 expands and contracts due to heat in the longitudinal direction, it has the advantage of being able to respond favorably while ensuring watertightness (reappointment n).

Next, in the invention recited in claim 2, in the structure of the invention recited in claim 1, a ladder-shaped frame member is placed on the valley gutter material 4 and between both arabesque materials 7. 1
3 is placed and fixed, and the mesh body 15 is stretched over this ladder-shaped frame material 13 to create a valley repair structure on the horizontal roof.
In particular, the mesh body 15 can prevent snow from falling and prevent the flow of snowmelt water from being obstructed.Secondly, it can avoid the sugamore phenomenon, and thirdly, it can prevent snow from falling. The configuration of the ladder-like frame material 13 with the net body 15 is also simple,
It has the advantage of being able to be constructed at a relatively low cost.

To explain these effects in detail, first, the descending valley (a) part of a horizontal roof has a V-shaped cross section and is sloping, so it is an extremely common part of the roof where snow accumulates. At such locations, the presence of the net 15 of the ladder-like frame material 13 provided on the valley gutter material 4 prevents the snow from falling off the net 15.
A gap is formed between the gutter material 4 and the net body 15, and the snowmelt water flows down extremely smoothly in this gap, and there is a great effect that the snow melt water can be suitably prevented from interfering with the flow.

Furthermore, because of this, snowmelt water does not accumulate,
It is possible to avoid the phenomenon of water leakage, and in turn, it is possible to reliably prevent rainwater from entering indoors.

In addition, the ladder-like frame material 13 with the net body 15 is simply made into a frame rod and has a simple structure, so it can be used as a descending valley (
b) It can be installed at a relatively low cost even if it is installed at a certain location.

In addition, since the structure of the invention other than this is the same as that of the invention of item 1, it can exhibit the same effect as this invention.
