Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves structure with a vertical roof suitable for buildings such as gymnasiums, warehouses, factories and clubhouses.

[0002]

2. Description of the Related Art In this type of roof, if a roof plate having a flat upper surface is used, it opens at the eaves. It is necessary to waterproof this opening by closing it with a cap material having the same outer shape as the cross-sectional shape of the roof board or covering it with a drain board. FIG. 6 shows an example using a draining plate.

The above-mentioned vertical roof will be described with reference to the embodiment of the present invention shown in FIG.
Elastically engages the through suspension 11 fixed to the roof plate 5
-Fixed by the cap 16 that is press-fitted between the five. A gutter body portion 9 is integrally provided at the inner end of the joint portion of the roof plates 5, 5, and rainwater that has infiltrated the joint portion can flow down to the eaves through the gutter body portion 9 or the through suspension 11.

As shown in FIG. 6, the eaves are waterproofed by a draining plate 46 fixed to the eaves frame 45. That is, the eaves-end frame 45 is fixed near the edge of the eaves on the exterior base material 4, and the draining plate 46 is fixed to the outer surface thereof with the rivets 48. A receiving wall 49 is bent forward at the upper end of the draining plate 46, and a continuous end edge of the main surface wall 6 of the roof plate 5 with the connecting portion cut out is hooked on the receiving wall 49. Similarly, the continuous end edge of the upper wall of the cap 16 is also hooked on the receiving wall 49. 50 is a rain gutter, 51 is a gutter receiver, and 52 is a drainage drain.

In the present invention, an aluminum profile is used as the eaves arabesque, but this kind of eaves arabesque is widely used for a thatched roof and is well known. However, in a thatched roof, it is not assumed that rainwater will infiltrate from the joint part of the roof plate, and it is considered that the infiltrated rainwater is drained down by using the joint part as a gutter as described above. Absent.

[0006]

As described above, in the waterproof structure of the draining plate 46 whose upper end is cantilevered, a gap is provided between the lower end of the draining plate 46 and the rain gutter 50. It is necessary to flow down the rainwater that has entered the trough body portion 9 at, and wind and rainwater easily enter through the gap as shown by the arrow in FIG. Since it is necessary to discharge rainwater that intrudes from the adjacent gaps between the roof plate 5 and the cap 16 at the eaves and the rainwater that flows down through the suspension hangers, it is not possible to close the drainboard 46 to the rain gutter 50 to eliminate the gap. . In addition, when the wind is strong, the draining plate 46 may be pushed and separated from the eaves frame 45, and the waterproof function may be completely impaired.

An object of the present invention is to provide an eaves structure for a thatched roof, which is excellent in waterproofness and wind resistance and can surely discharge rainwater that has flowed down into the eaves arabesque. Another object of the present invention is to firmly lock the roof plate to the eaves arabesque and to fix it, and thus, when the roof plate is subjected to a strong external force and is shaken in the longitudinal direction, or is thermally deformed in the longitudinal direction, The purpose is to provide a robust eaves structure for a thatched roof that can remain hung.

[0008]

According to the present invention, as shown in FIG. 3, the adjacent roof plates 5.5 are elastically engaged with the suspensions 11 fixed to the inner layer base material 2, respectively. It is premised on a vertically-roofed roof in which a cap 16 for maintaining the engagement state between both members 5 and 5 is press-fitted and engaged. Then, the eaves arabesque 23 made of an extruded aluminum material is arranged at the eaves edge of the inner layer base material 2. The eaves arabesque 23 is attached with a mounting portion 27 having an inverted L-shaped cross section as shown in FIGS. 1 and 2. A hollow frame portion 28 that continuously protrudes forward from the portion 27,
A roof receiving portion 29 that projects upward from the upper end of the front surface of the frame portion 28 and receives and supports the eave edges of the roof plate 5 and the cap 16.
It has and. Between the rain gutter 24 supported by the roof support member 1 and the eaves arabesque 23, a draining plate 22 for closing a gap between the two 23.24 is provided. Roof board 5 and cap 16
The hooking edges 36 and 37 provided at the eaves end are hooked and connected to the outermost receiving wall 35 of the roof receiving portion 29, respectively. Then, water drainage holes 32 are provided at predetermined intervals in the horizontal wall 31 of the frame portion 28.

The frame portion 28 is an upper wall 27b of the mounting portion 27.
A pair of upper and lower horizontal bridge walls 31 and 31 projecting forward from the front wall 27a below and a vertical frame wall 30 provided in parallel with the front wall 27a are formed in a rectangular cross section. Further, the roof receiving portion 29 is formed in a U-shaped cross section that opens downward,
The roof wall 5 and the hooking edges 36 and 37 of the cap 16 are hooked and connected to the receiving wall 35 protruding downward.

[0010]

The eaves opening of the roof board 5 is closed by the eaves arabesque 23 made of extruded aluminum, which prevents rainwater from entering the attic, so that a reliable waterproofing action can be obtained. Moreover, the rainwater that has flowed into the eaves arabesque 23 can be drained through the drainage hole 32 provided in the horizontal wall 31 without any trouble. Drainer 22
Prevents rainwater from seeping in between the eaves arabesque 23 and the rain gutter 24. Since the attachment portion 27 and the roof receiving portion 29 are connected by the hollow frame portion 28, the structural strength of the eaves arabesque 23 itself can be increased and the wind resistance can be improved.

In particular, in the eaves arabesque 23 having the pair of upper and lower horizontal walls 31, 31, the roof receiving portion 29 can be firmly supported, and the horizontal walls 31 and 31 block the inflow of rainwater both inside and outside. It will be. When the roof plate 5 and the cap 16 are hooked and connected to the receiving wall 35 protruding downward of the roof receiving part 29, when an external force or a thermal deformation force in the longitudinal direction acts on the roof plate 5 and the cap 16. Also, these are absorbed by elastic deformation of the hooking edges 36 and 37, and the connected state is well maintained.

[0012]

According to the present invention, the eaves arabesque 23 is made of an extruded aluminum material having the mounting portion 27, the frame portion 28, and the roof receiving portion 29, and the eaves opening of the roof board 5 is closed with this to waterproof.

That is, the rainwater that inevitably invades the inside of the eaves arabesque 23 can be drained through the drain holes 32 provided in the horizontal wall 31 without hindrance, while maximally preventing the intrusion of wind and rain from the outside. As a result, an eaves-edge structure having sufficient waterproofness and wind resistance and, in addition, the rainwater discharge function that is indispensable for a thatched roof can be obtained.

The roof plate 5 and the cap 16 are bent downward to form hooking edges 36 and 37, which are hooked and connected to the receiving wall 35 projecting downward. Even when external force in the longitudinal direction or thermal deformation is applied to these, these are applied to the locking edges 36 and 37.
It is possible to absorb the elastic deformation and maintain the connected state well, and a strong eaves structure that is strong against abnormal climate and earthquake can be obtained, which is particularly suitable for a large building where a long and flat roof plate 5 is used. .
