DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat roofing material, in which a connecting piece is formed by being bent downward, and connecting pieces of an adjacent roofing material are connected to each other by a suspension and connected to the connecting piece. The roof is provided with a gutter member below the gutter member and a field plate having a heat insulating function is provided below the gutter member. Specifically, the heat insulation function of the field plate is degraded by dew condensation generated on the gutter member. The present invention relates to a technique for reducing the pressure and effectively utilizing such a configuration so that the water gradient of the gutter member can be set regardless of the gradient of the roof.

It was something that was closely attached.

[0003]

However, when the gutter member is in close contact with the field plate using the heat insulating material as described above, the dew water condensed on the gutter member permeates the field plate and deteriorates the heat insulation function. Also, since the gutter member is in close contact with the base plate,
The gradient of the gutter member cannot be changed, there is no water gradient,
Or on a roof with a small water gradient, such as a flat roof,
There was a problem that it was difficult to enhance the drainage function of rainwater that entered from the connection point of the roofing material.

An object of the present invention is to solve such a problem and to reduce the deterioration of the heat insulating function of a field board due to dew water generated in a gutter member, and to make effective use of such a configuration. Accordingly, an object of the present invention is to provide a roof capable of setting a water gradient of a gutter member irrespective of a roof gradient.

1 and 2 (b) are schematic sectional views, and FIG. 2 (a) is a perspective view of a main part. A field board 4 such as a wool cement board which is compressed and hardened at high pressure on a roof base 20 such as a purlin using mold steel.
Is laid. Asphalt roofing 14 is laid on the base plate 4.

The roofing material 1 is formed flat from a metal plate, and connection pieces 2 are bent on both sides of the roofing material 1 at a substantially right angle to the roofing material 1 and substantially inwardly upward from the lower end of the connection piece 2. The L-shaped supported piece 7 is bent. The hanging member 5 is formed by bending the standing piece 10 from the fixed piece 9, extending the horizontal piece 11 from the upper end of the rising piece 10, and bending the substantially L-shaped support piece 6 at the tip of the horizontal piece 11. I have. A substantially U-shaped gutter receiver 8 having a relatively shallow bottom is supported by the suspender 5 by welding, for example.

[0010] Then, on the asphalt roofing 14 laid on the base plate 4 such as a wood wool cement board, heat insulating materials 12, 12 having the same specifications as the base plate 4 are laid.
A connection space E for the roof materials 1, 1 is formed between the two heat insulating materials 12, 12. In this connection space E, suspenders 5 and 5 provided with gutter receivers 8 are disposed, and drill screws 1 and 5 are fixed at fixing pieces 9 and 9.
3 is penetrated through the base plate 4 and is driven into the roof foundation 20 to fix the suspender 5. In this case, the upper part of the gutter receiver 8 supported between the suspenders 5, 5 is open, and the gutter member 3 is placed and supported on the gutter receiver 8, and the gutter member 3 and the base plate 4 are opened. To form a gap S. Next, the roofing materials 1 and 1 are placed on the heat insulating materials 12 and 12, and the connecting pieces 2 and the supported pieces 7 of the roofing material 1 are placed under the supporting pieces 6 of the suspenders 5 by utilizing these elastic deformations. By pushing and elastic restoration of the supported piece 7 etc.,
The supporting pieces 7 are pressed by the supporting pieces 6 and the connecting pieces 2 and 2 are pressed against each other to connect the roof materials 1 and 1.

Thus, the gutter member 3 floats from the base plate 4 to form a gap S, and it is possible to prevent the dew water condensed on the gutter member 3 from seeping into the base plate 4 using the heat insulating material.
Deterioration of the field board 4 can be reduced. Moreover, the water gradient of the gutter member 3 can be appropriately changed by changing the height of the suspenders 5 arranged at appropriate intervals from the eaves to the ridge.

FIGS. 3 and 4 show another embodiment, in which a connecting piece 2 of a roofing material 1 is folded back along a side end of the roofing material 1. FIG. On the other hand, the support piece 6 of the suspender 5 is formed substantially horizontally. A space seat 18 is interposed between the base plate 4 and the heat insulating material 12, and
An empty space X is formed between the heat insulating material 12 and the heat insulating material 12. As shown in FIG. 4, the roof material 1 has a crosspiece 15 interposed between the roof material 1 and the heat insulating material 12 at a substantially central portion in the width direction to flex the roof material 1 a little and at both ends. The connection pieces 2 and 2 are engaged with the support pieces 6 of the suspenders 5 and 5 with a sealing material 17 interposed therebetween. Other configurations are the same as those in FIGS. 1 and 2, and the same components are denoted by the same reference numerals and description thereof will be omitted.
