Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side-roof structure applied to various roofing materials for buildings (metal side-roofing, press roofing tile, roofing tile, natural slate, tiles, etc.).

[0002]

2. Description of the Related Art Conventionally, in such a type of thatched roof structure, when the lateral thatched roof members are connected in the lateral direction, the actual construction of the roofed roof structure is performed.
There is a structure having a joint member as disclosed in Japanese Patent Laid-Open No. 100720.

In such a roofing roofing material, a ridge-side engaging portion bent upward to the ridge side and an eave-side engaging portion bent downward to the eaves side are formed, and the roof eaves direction ( When connecting each of the horizontal roofing materials adjacent to each other in the vertical direction, the ridge-side engaging portion and the eave-side engaging portion are engaged with each other.

On the other hand, a joint member used for connecting lateral roofing roof members in the lateral direction is formed by raising the ridge side of the board to the upper side and folding the eaves side to the lower side. At the end edge portion, a rising edge or a folding edge is formed to stop water.

Then, in order to connect the lateral thatched roof members in the lateral direction by using the joint member, the joint members are arranged on the back surfaces of the side edges of the lateral thatched roof members which are adjacent to each other in the lateral direction, and the substrate is almost While inserting the side edge of the roofing roofing material into the roofing material locking portion of the joiner member arranged in the center, insert the folding portion into the eaves side engaging portion of the roofing roofing material, and further This is done by locating the standing portions outside the ridge-side engaging portions of the thatched roofing material.

In this way, the side-roof roofing material connected by the joint member has its ridge-side engaging portion fixed on the base member by a fixture such as a hanging member, and The eaves-side engaging portion of the lateral thatched roof material arranged on the ridge side is sequentially raised by engaging the eaves-side engaging portion of the eaves side thatched roofing material, at this time, the joint member The lower end of the folding part is located between the ridge-side engaging part and the eaves-side engaging part in the eaves-side engaging part of the roofing roofing material.

[0007]

However, in the above-mentioned conventional structure, the side edge portions of the lateral thatched roofing materials that are laterally adjacent to each other and the joint member into which the side edge portions of the lateral thatched roofing material are inserted are inserted. Rainwater entering from the connecting part of the joiner member of the roofing material with the roof material locking part must be allowed to flow out onto the lower thatched roofing material, but the joint member must be attached to the back of the side edge of the adjacent thatched roofing material. Since it is arranged, since it is fitted in the engaging portion of the roofing roofing material, it is necessary to suppress the thickness of the substrate forming the joint member as much as possible, thereby reducing the flow passage cross-sectional area, Rainwater cannot be drained effectively.

Further, in the case of using the joint member having a small flow passage cross-sectional area as described above, the rainwater that has infiltrated onto the substrate cannot be completely discharged and is formed on the side edge thereof in an abnormal weather such as a storm. There is a risk that rainwater may get over the standing piece or the folded piece for stopping water and enter the room to leak rain.

Further, the lower end of the folded portion of the joint member is located between the ridge-side engaging portion and the eave-side engaging portion within the eave-side engaging portion of the side-roofing roofing material and penetrates onto the substrate. The rainwater that has flowed down flows into the engaging part of the thatched roofing material along the folded part of the board, and is discharged from the engaging part of the thatched roofing material onto the lower thatched roofing material. Therefore, the rainwater when it cannot be completely discharged on the lower thatched roofing material flows laterally along the eaves side engaging part of the thatched roofing material,
The rainwater flowing in the lateral direction is likely to stay in the engaging portion of the horizontal roofing material, which may cause corrosion of the horizontal roofing material.

Conventionally, as disclosed in Japanese Utility Model Laid-Open No. Sho 49-81522, there is a structure in which a gutter member is arranged on the lower surface of a joint member for connecting roof materials adjacent to each other. Such a conventional structure is a technique for a so-called thatched roof, and cannot be applied to a horizontal thatched roof structure like the present invention.

An object of the present invention is to increase the flow passage cross-sectional area of rainwater so that rainwater can be reliably prevented from leaking to the indoor side even during abnormal weather such as storms. An object of the present invention is to provide a lateral thatched roof structure capable of easily performing thatching work.

[0012]

In order to solve the above problems, the present invention provides a base member such as a purlin, and a gutter-shaped running water member vertically arranged on the eaves side of the base member. On the rafter member arranged in the water flow member, a first fixing member for fixing the rafter member and the water flow member to each other on the base member, and on the rafter member fixed by the first fixing member. Lateral roofing materials laid by arranging the mutually adjacent ends in the lateral direction at a predetermined interval, and the adjacent ends of these lateral thatch roofing materials are sandwiched and fixed on the rafter member. The second fixing member and a cover member fixed to the second fixing member in a fitted state and covering the adjacent ends of the roof material with each other.

[0013]

That is, according to the present invention, the rafter member is arranged in the gutter-shaped running water member vertically arranged on the eaves side on the base member,
While fixing the rafter member and the running water member on the base member by the first fixing member, the adjacent ends of the adjacent thatched roofing members which are laterally adjacent to each other are arranged on the rafter member at a predetermined interval. , The adjacent ends of these thatched roof materials are sandwiched and fixed on the rafter member through the second fixing member, so that the running water members are disposed so that the adjacent ends of the thatched roof material are adjacent to each other. The cross-sectional area of the flow path of the water infiltrated from is increased, and a large amount of infiltrated water can be processed, and this infiltrated water is received by the running water member, guided to the eaves side, and discharged from the eaves side. It is possible to prevent the leakage of the infiltration water to the outside of the rafter member, and the infiltration water does not flow into the eaves side engaging portion of the horizontal roofing material.

On the rafter members, adjacent ends of laterally-roofing roofing members which are laterally adjacent to each other are arranged at a predetermined interval, and adjacent ends of the laterally-roofing roofing members are rafter members. Since it is held and fixed via the second fixing member above,
The roofing work can be performed easily, and roof fixing tools such as hangings around the adjacent end of the horizontal thatched roof material are not required.

Moreover, since the adjacent end portions of the side-roofing roofing material are pressed and fixed from above by the second fixing member, even if a negative pressure acts on the roofing material due to strong wind during abnormal weather such as storm. , The roofing material does not float up.

Further, a cover member is attached in a fitted state together with the adjoining ends of the thatched roofing material being held by the second fixing member, and the adjoining ends of the thatched roofing material are covered by this cover member. As a result, the work of attaching the cover member can be performed easily, and it is possible to minimize the intrusion of water from the adjacent ends of the side-roofing roofing materials, and moreover, in terms of design. Great effect.
