Description

[Detailed description of the invention] (Industrial application field) This invention is applied to the inside corner of a roofing board, which is installed on the side of the inside corner of a building frame, and is made by using roofing boards with seams. Regarding the roof.

(Prior Art) Conventionally, a roof installed at the corner of a building has one side horizontally attached to the side of the building frame, and the other side that intersects with this side slopes downward to the side that intersects with the side. It has been installed. In order to protect the roof from the rain at the corner where it connects to the building frame and the outer wall, roofing boards such as galvanized iron are installed with seams, and the horizontal and slanted attachment areas of the roof are protected from rain. These roofing boards were then stood up vertically along the building frame, bent and fixed to the building frame, and then the exterior walls were installed.

(Problems to be Solved by the Invention) In the case of the above-mentioned conventional technology, rain that hits the outer wall and rain that is blown by the wind flows along the attachment part of the roof. Here, since the horizontal mounting part is inclined in a direction perpendicular to the mounting part, rainwater does not accumulate in the mounting part, and rainwater does not infiltrate into the building. However, the slanted mounting part is parallel to the direction of the roof's inclination, and all the rainwater that has fallen from the wall surface and the rainwater that has blown over flows along the corners of this mounting part, and the amount increases as it goes downward. . Therefore, when it rains, a large amount of rainwater always flows into the corner of the slanted mounting part of a conventional corner roof, and rainwater flows between the outer wall and the roofing board and from the joints of the seams. There was a problem that it was easy for people to enter the building. especially,
It is extremely difficult to completely seal the joint between the seam and the exterior wall, and the deterioration of the sealing material is unavoidable, so it is inevitable that rainwater will enter this area after years of use. .

This invention was made in view of the problems of the conventional technology described above, and provides a corner roof that prevents rainwater from penetrating into the building from the sloping attachment part of the corner roof. The purpose is to

(Means for Solving the Problems) This invention provides a method for attaching a roof in a direction perpendicular to the direction of inclination to an inclined attachment part of the attachment part between the roof main body and the building frame, which is provided at the corner of a building. A sloped member having an inclined surface is provided, a roofing board is attached along this sloped member, and the roofing board is installed along the sloped member with an outer wall provided on the building frame. This is a corner roof with a part of the slope exposed to the outside.

(Function) In the corner roof of this invention, the inclined member provided at the inclined attachment part to the building frame prevents rainwater from concentrating on the joining member between the roofing board and the outer wall, and the rainwater is transferred to the inclined member. The water flows downward along the roof.

(Example) Hereinafter, an example of this invention will be described based on FIGS. 1 to 3.

The roof 2 attached to the side of the corner of the building body 1 has a top plate 4 on top of the rafters 3, and a roof 5 on top of the roof 4 at right angles to the rafters 3. A roof main body 7 is formed by pasting a roofing board 6 on top. This roof body 7 has a rectangular shape, and one side of the roof body 7 is attached horizontally to the side surface of the inside corner of the building frame 1, and the other side that intersects this side is attached downwardly to the side surface that intersects with the side surface of the inside corner. It is installed at an angle.

Among the attachment parts of the roof body 7, a surface 9 inclined downward in a direction perpendicular to the inclination direction of the roof body 7 is provided at a corner formed by the roofing board 6 of the inclined inclined attachment part 8 and the building frame 1. A tilting member 10 is attached. The inclined member 10 is a triangular prism having a wedge-shaped cross section and a length shorter than the length of the inclined mounting portion 8. The installation of this inclined member 10 is as follows:
Leave both ends of the inclined mounting part 8 open by approximately the same length,
The base end of the wedge shape is fixed to a corner of the building frame 1 so that it comes into contact with the building frame 1.

The roof 2 at the entrance corner is constructed by placing roofing boards 11 such as long galvanized iron plates with seams on the long sides parallel to the top surface of the shedding board 6 and with the seams horizontal. The roofing board 11 is laid down in sequence, and at the attachment point between the roof 2 and the building frame 1, the roofing board 11 forms a rising portion 11a that rises vertically along the building frame 1. In addition, in the inclined attachment part 8, the roofing board 11 is laid along the inclined surface 9 of the inclined member 10, and rises vertically at the position where it contacts the building frame 1 to form a rising part 11a. are doing. Further, at both ends of the inclined member 10, the roofing plate 11 forms a triangular surface 11b at each end with both ends of the inclined mounting portion 8. Here, this triangular surface 11b is formed by bending a single roofing board 11. Therefore, the end of the inclined mounting part 8 and the inclined member 10
The length of the inclined member 10 is determined so that the distance from the end thereof is smaller than the width of the roofing board 11.

This corner roof 2 is constructed by fixing the roof body 7 to the building frame 1, attaching the inclined member 10, and laying roofing boards 11, and then attaching an outer wall 12 of mortar or the like to the building frame 1. . With this outer wall 12 provided, a part of the inclined surface 11c of the roofing board 11 laid on the inclined surface 9 of the inclined member 10 is exposed from the outer wall surface. Furthermore, outer wall 1
A sealing material 13 is packed in the joint between the roofing plate 2 and the roofing board 11.

As a result, rainwater flowing down from the outer wall 12 flows in an inclined direction along the inclined surface 11c, and flows down along the slope of the roof 2 below the inclined surface 11c. Further, rainwater blown by the wind onto the inclined attachment part 8 of the roof 2 does not go up the inclined surface 11c in the opposite direction, but flows down along the slope of the roof 2 below the inclined surface 11c. Therefore, rainwater does not flow downward along the joint between the outer wall 12 and the roofing board 11.

According to the roof at the corner of this embodiment, since the sloped surface 11c is formed on the roofing board 11 of the inclined attachment part 8, rainwater is concentrated at the joint between the outer wall 12 and the roofing board 11. It does not flow in large quantities.
Furthermore, even if the sealing material 13 deteriorates over time, rainwater will not be concentrated at this joint, so it is possible to effectively prevent rainwater from penetrating into the building.

Further, the ends of the inclined member 10 are positioned slightly apart from both ends of the inclined mounting portion 8, and at both ends, the roofing board 11 is treated by forming a triangular surface 11b, It prevents rainwater from entering from the edges and has a good appearance.

Note that the roofing boards for the corner roof of this invention are not limited to long ones, but may also be rectangular boards arranged vertically and horizontally to cover the roof. Also,
The inclined member may be integrated with the roofing board, or may be of a structure in which the roofing board is simply supported at two or more points so that it is inclined.

(Effect of the invention) The roof at the corner of this invention is equipped with an inclined member having an inclined surface perpendicular to the direction of the slope at the inclined attachment point to the building frame, so that rain water that flows down from the side wall of the corner can be removed. This prevents rainwater from flowing concentratedly along the joint between the outer wall of the sloping mounting part and the roofing board, thereby effectively preventing rainwater from entering the building from the sloping mounting part. It is something that can be prevented.

Furthermore, rainwater that is blown by the wind onto this slanted mounting part does not reach the joint between the exterior wall and the roofing board, but flows down along the slope of the roof below the sloping surface, and is carried away by the wind. It can also prevent rainwater from entering the building. In particular, even if the watertightness of the joint between the roofing board and the exterior wall is not perfect due to seams or has deteriorated over time, rainwater will flow down along the slope of the sloped member, making it difficult to Infiltration of rainwater into the building can be minimized.
