Abstract

PURPOSE:To conduct the mounting operation of an eave gutter in the framework section of a building, and to improve the safety of operation by forming a shoot penetrated to an eave rear to a roof panel and discharging rainwater toward the eave gutter installed on the lower side of the shoot. CONSTITUTION:The shoot 12 of rainwater is bored to a roof panel 1 projected in the direction of eaves while being penetrated through an eave rear, and rainwater flowing down from the shoot 12 is collected in an eave gutter 7. An external guide plate 14 and an internal guide plate 16 guiding rainwater into the eave gutter 7 are mounted on the eave side and roof top section side of the shoot 12 respectively on the rear of the roof panel 1 at that time. The internal guide plate 16 and the upper end of the eave gutter 7 are overlapped in the internal and external directions of a building, thus forming a ventilation path 18 between the guide plate 16 and the upper end of the eave gutter 7. A garret space 17 communicates with the outside to take up sufficient ventilation. Accordingly, the eave gutter 7 can be installed safely on the framework side of the building such as an external wall.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain protection device for eaves of a building.

[0002]

2. Description of the Related Art Generally, in a building having an eaves structure in which the tip of the roof projects outward with respect to the outer wall of the building, a gutter is attached to the eaves end of the roof via a gutter bracket. There is.

[0003]

However, in order to attach the eaves gutter to the tip of the roof as described above, the beam or other frame of the roof truss capable of attaching the gutter bracket is extended to the tip of the eaves. It is necessary to be issued. That is, in the case where the roof of the eaves part is composed of only one thin iron plate, there is not enough strength to attach the above metal fittings or eaves gutter and the nose cover covering the outside of the eaves gutter. There is. Further, the work for attaching the eaves gutter has to be performed at the tip of the eaves, which is difficult and is dangerous. The present invention solves the conventional drawbacks described above, and provides a rain warding device for the eaves part that can discharge rainwater from the roof to the eaves without attaching the eaves gutter to the tip part of the eaves roof. That is the purpose.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a roof panel projecting in the eaves direction from a building with a rainwater outlet opening penetrating to the back of the eaves. It is characterized by being provided with eaves gutters corresponding to the outlets to collect rainwater flowing from the outlets.

In the above, it is conceivable to install a guide on the back surface of the roof panel for guiding rainwater falling from the outlet to the eaves gutter.

This guide is composed of an outer guide plate provided on the eaves side of the outlet and an inner guide plate also provided on the roof top side of the outlet.

Further, in the invention of claim 4 of this application, the inside guide plate and the upper end of the eaves gutter are overlapped in the inside and outside directions of the building, and the attic space is provided between the guide plate and the upper end of the eaves gutter. There is provided a ventilation passage for communicating the space with the outside.

[0008]

[Function] As described above, most of the rainwater that flows down the roof surface flows down from the outlet to the eaves gutter and is discharged. Even if no eaves gutter is provided at the tip, the flow rate of the rainwater that falls from the roof tip is reduced. It can be greatly reduced.

1 shows a building with a semi-cylindrical vault roof. In the figure, (1), (1), ... Are roof panels made of steel plates curved in a semicircular shape when viewed from the wife side of the building, and a plurality of roof panels (1), (1), ... And are mounted side by side to form the vault roof.

FIG. 2 shows a cross section of the eaves side tip portion of the roof panels (1) and (1). (2) is a beam in the girder direction of the building and is made of H-shaped steel,
The flanges (3) and (3) are arranged parallel to the inside and outside directions of the building. The gutter receiving fittings (5) are fixed to the upper end portions of the flanges (3) and (3) via angle members (4) and (4). A tip portion of the gutter receiving fitting (5) outside the building is formed into a U-shape with an open upper end to form a gutter receiving portion (6). The eaves gutter (7) having a groove cross section in the girder direction is fitted and attached to the gutter receiving portion (6) from above. The upper end of the vertical part (8) inside the building of the eaves gutter (7) extends to near the back surface of the roof panel (1) above the vertical part (8).

Then, the roof panel (1) made of an iron plate is provided with a spout for dropping rainwater toward the eaves trough (7) so as to correspond to the upper end open portion of the eaves trough (7). (12) is opened. The outlets (12) are arranged in multiple rows at intervals in the girder direction of the roof panel (1). Although not shown, the roof panel (13) (13)
A frame material for attaching 1) to the beam (2) side, which is fixed to the back surface of the roof panel (13) in advance. The tip of the frame (13) has the gutter (7). The outer guide plate (14) along the girder direction is fixed so as to project downward, and rainwater that has fallen from the outlet (12) , So that it does not flow out beyond the vertical part (15) outside the eaves gutter (7). On the other hand, on the roof top side of the outlet (12), on the back surface of the roof panel (1), hang down to a position closer to the inside of the eaves gutter (7) than the vertical part (8) inside the eaves gutter (7). In this way, the inner guide plate (16) is fixed so that rainwater that has fallen from the outlet (12) also does not enter the back of the hut beyond the upper end of the vertical portion (8) inside thereof. .

At this time, a gap (17) is formed between the inner guide plate (16) and the inner vertical portion (8), and passes through above the eaves gutter (7) to the back side of the shed. A ventilation passage (18) is formed for introducing ventilation. That is, there is a gap between the roof panel (1) and the upper part of the vertical part (15) outside the eaves gutter (7), and the outside air introduced through this gap is It is introduced into the back of the hut through the inner gap (17). (1
9) is a draining plate which is bent substantially inward from the upper end of the outer vertical portion (15) of the eaves gutter (7) and protrudes.
A nasal concealed plate (21) having a U-shaped cross section is attached to the outside of the vertical portion (15) of the eaves gutter (7) through a support fitting (20).

(23) is the outer wall portion of the building,
A gutter arranged at one end in the girder direction, and the upper end of the gutter (23) is connected to the eaves gutter (7) via the drop gutter (24) inserted into the gutter (23). ), The rainwater that has fallen into this eaves gutter (7) flows down from the vertical gutter (23).

[0014]

As described above, according to the present invention, the rainwater outlet is provided in the middle portion of the roof panel, and the rainwater flowing along the roof panel is directed toward the eaves gutter provided below the rainwater outlet. It is not necessary to provide eaves gutters at the tip of the eaves of the roof panel because it is designed to discharge. Therefore, even in such a thin-walled iron plate roof where it is not possible to attach such eaves troughs or supporting metal fittings to the roof panel tip, most of the water is discharged to the eaves trough without dropping rainwater from the eaves tip side. The effect is that you can do it. Further, since it is not necessary to attach a gutter to the tip of the roof panel eaves, the eaves can be attached to the frame side of the building such as the outer wall, and the work can be performed in the frame part of the building, so that the work can be performed safely.

Further, since a ventilation passage is formed by providing a gap between the inner vertical portion of the eaves trough and the inner guide plate, the eaves trough is thus provided corresponding to the back surface of the roof panel. Even though the structure is provided, the effect of being able to take in sufficient ventilation without obstructing the ventilation of the attic by this eaves gutter is obtained.
