Description

[Detailed Description of the Invention] The present invention relates to a roof using a hollow roofing material having excellent physical properties such as rigidity and appearance.

Conventionally, when hollow roofing materials are used for terraces, entrance eaves, or carports of houses, for example, as shown in FIG. The rainwater flowing on the hollow roofing material 1' is collected by a water collector 3' and drained by a downspout 4', or as shown in Fig. 6.
The end opening of the sloped hollow roof material 5' is closed with an end cap 6', and a parapet 8' with a gutter 7' integrally formed is attached to the eaves, and rainwater is transmitted through the chain gutter 9'. Water may be drained. However, as in the former case, if nothing is attached to the end opening of the hollow roofing material 1' and construction is carried out with the hollow part 1'a of the hollow roofing material 1' left open, rainwater and dust may be blown up by the wind. As a result, dirt and dust accumulate in the hollow part 1'a, causing dirt, and in the latter case, the connection between the end cap 6' and the hollow roofing material 5' Rainwater enters the hollow part of the hollow roofing material 5 due to capillary action, and the water collected inside is heated by solar heat and vaporizes, causing dew condensation, which can impair transparency and appearance, and cause damage to the inside of the hollow part. There was a drawback that the high temperature caused the hollow roofing material 5' to deform and deteriorate its durability.

The present invention was made with the aim of solving the conventional drawbacks as described above, and its gist is a hollow roofing material in which a top plate and a bottom plate are connected by a number of connecting plates along the longitudinal direction. On the back side of the front panel, between the upper panel, the lower panel, and the upper and lower panels, a plurality of ribs are provided at intervals in the longitudinal direction and a convex portion that fits into the hollow part of the hollow roofing material. The rib has a shape corresponding to a hollow roof material, and the rib is shorter than the convex part and spaced apart from the bottom plate, and the gap between the convex part and the top plate is the same as that of the top plate. It is larger than the thickness of the roof, the rear end of the lower plate is raised to form a gutter, and the lower plate is equipped with an end cap and a rainwater drainage member, and is mounted on a main building fixed to a pillar. The hollow roofing material is fixed by being tilted in the longitudinal direction, and the convex part of the end cap is fitted into the hollow part at the lower end of the hollow roofing material, and between the end surface of the hollow roofing material and the back surface of the front plate of the endcap. Also, gaps for rainwater drainage are formed between the upper surface of the top plate of the hollow roof material and the lower surface of the upper surface plate of the end cap, and a rainwater drainage member is provided below the drainage hole of the end cap.

Hereinafter, the present invention will be explained with reference to embodiments of the drawings.

and a bottom plate 25 are provided. A plurality of ribs 23... and a plurality of convex portions 24... are provided alternately in a portion slightly closer to the upper surface plate 22 between the upper surface plate 22 and the lower surface plate 25, and the ribs 23 are shorter than the convex portions 24 and are lower. The space is spaced apart from the face plate 25,
The gap between the convex portions 24... and the lower surface of the top plate 22 is made considerably larger than the thickness of the top plate 11 of the hollow roofing material 1, and as shown in FIG. The portion 24 is fitted and its end surface is connected to the rib 2.
3, a rib 23 is formed between the end surface of the hollow roof material 1 and the back surface of the front plate 21 of the end cap 2.
A gap corresponding to the protrusion length is formed between the upper surface of the top plate 11 of the hollow roofing material 1 and the lower surface of the upper surface plate 22 of the end cap 2, and a gap between the convex portion 24 and the lower surface of the upper surface plate 22. A gap corresponding to the thickness of the top plate 11 is formed, rainwater flows down from each gap, and the rear end of the bottom plate 25 is raised to form a gutter part 27. Drain holes 26, 26 are provided at both ends of the bottom plate 25.

FIG. 4 is a perspective view showing an embodiment of the present invention.
A plurality of hollow roofing materials 1 are arranged on the main building material 32 fixed on the pillars 33, 33 at an angle in the longitudinal direction, adjacent connecting parts are connected to each other, and the main building material 32 is fixed on the pillars 33, 33. It is fixed to the material 32. At the lower end of each hollow roofing material 1..., an end cap 2...
As shown in FIG. 3, the convex part 24 is fitted into the hollow part 14 of the hollow roofing material 1, and its end surface is brought into contact with the rib 23, and the end surface of the hollow roofing material 1 and the front of the end cap 2 are brought into contact with each other. Between the back surface of the face plate 21 and the upper surface of the top plate 11 of the hollow roofing material 1 and the upper surface plate 21 of the end cap
A gap is formed between the bottom surface and the bottom surface for rainwater to flow down. Below the drainage hole of the end cap 2..., a rainwater drainage member 3 is provided which is connected to a hollow hanging pipe 31..., a hollow purlin 32, and hollow pillars 33, 33, and the rainwater drainage member 3 is connected to Rainwater is made to flow down from the drainage hole of end cap 2.

The rainwater drainage member is not limited to those mentioned above, and may be a chain gutter or the like. Also, only one hollow roofing material 1 may be used.

In the roof of the present invention, a hollow roofing material is fixed in the longitudinal direction on the purlin material fixed on the pillars, and in the hollow part of the lower end of the hollow roofing material, the upper surface plate, the lower surface plate and the upper A plurality of ribs arranged at intervals in the longitudinal direction and a convex portion that fits into the hollow part of the hollow roofing material are provided between the bottom plates, and the overall shape is compatible with the hollow roofing material. , the rib is shorter than the convex part and spaced apart from the bottom plate, the gap between the convex part and the top plate is larger than the thickness of the top plate, and the rear end of the bottom plate is raised up. The convex part of the end cap, which has a drainage hole formed in the bottom plate, is fitted into the gap between the end face of the hollow roofing material and the back surface of the front plate of the end cap, and the top plate of the hollow roofing material. A gap for rainwater drainage is formed between the top surface and the lower surface of the top plate of the end cap, and a rainwater drainage member is provided below the drainage hole of the endcap, so dust etc. will not enter the hollow part of the hollow roofing material. It is possible to prevent adhesion and keep the hollow roofing material beautiful for a long time.Rainwater flowing on the hollow member and water that has entered the hollow part can be collected in the end cap and drained through the rainwater drainage member. Moreover, since conventional eaves gutters are not required, construction is easy and costs can be reduced, and the eaves can be made to look clean and beautiful.

In addition, ribs are provided on the back side of the front plate of the end cap, and a gap is formed between the end of the hollow roofing material and the back side of the front plate of the end cap, allowing rainwater to flow smoothly into the gutter. Also, since this gap also serves as a ventilation hole, water drainage inside the end cap is good, and the end cap itself has great strength due to the ribs, and the ends of the hollow roofing material are covered by this end cap. There is no possibility of warping or bending of the hollow roofing material.
