Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a surface structure forming the roof, outer wall, etc. of a building.

[Conventional technology]

BACKGROUND ART Conventionally, as a surface structure constituting a roof, one described in, for example, Japanese Utility Model Publication No. 57-15952 is known. However, in this planar structure, the rafters, which are the attachment members, are fixed to the outdoor side of the support member consisting of the main building, perpendicular to these, and the support members are erected between the rafters to form a frame, and the roof is placed on the outdoor side of the rafters. There was one with a board roof.

In addition, as shown in Japanese Patent Application Laid-Open No. 1984-19459,
A main gutter that also serves as a rafter is fixed vertically to the outdoor side of the support member, and the end of the branch gutter that is to be arranged horizontally between the main gutter protrudes into the groove of the main gutter, and the main gutter and branch gutter are A solar heat collector is placed on the outdoor side of the waterproof plate, and a solar heat collector is placed between the outer periphery of the transparent plate of these heat collectors. There was a roof with a cover to let it out.

[Problem that the invention seeks to solve]

However, in the former type of conventional roof, it is difficult to position and connect the edge portions of the roof panels perpendicular to the rafters, and it is also difficult to prevent rainwater from entering through the connecting portions. In addition, if long roof panels were used in the direction along the rafters to improve this problem, the roof panels would be large and heavy, making them difficult to transport and install, resulting in poor workability. .

In addition, since the conventional latter type of roof is equipped with a solar heat collector, it has a complicated structure, including a transparent plate on the outdoor side, a waterproof plate on the indoor side, and two inner and outer face plates. In addition to poor workability during construction, there were problems in that the cover bulged out toward the outdoor side of the transparent plate, making it look unsightly. When the solar heat collector is removed from the latter roof, a long protrusion protrudes from the bottom of the main gutter toward the outdoors, and the waterproof board is supported to the main gutter through insulation. Various problems arise, such as the possibility of instability, and it is impossible to use the heat collector with the heat collector removed.

The present invention solves the above-mentioned problems, has a relatively simple structure, can be constructed with good workability, reliably prevents water from leaking indoors from the joints of face plates, etc., and has a good-looking roof. The object is to provide a surface structure.

[Means for solving problems]

In the present invention, a main gutter which also serves as a mounting member for a face plate is vertically fixed to the outdoor side of a support member, and an end of a branch gutter disposed horizontally between the main gutter protrudes into a groove of the main gutter. In a building surface structure in which a part surrounded by a main gutter and a branch gutter is covered with a single face plate, the main gutter is provided with a wall facing inward in the width direction at the opening edge of both side walls. A protruding flange, a convex portion protruding on the groove bottom to a height lower than the opening edge, and a protrusion protruding from between the opening edge of both side walls and the groove bottom inwardly in the width direction, respectively. formed along the longitudinal direction, the convex part of the main gutter is fixed to the support member, and the end of the branch gutter is fitted into a notch provided on the side wall opening side of the main gutter to be supported by the protrusion. , the outdoor sides of the flange of the main gutter and both side plates of the branch gutter are arranged on the same or almost the same plane, and the opposite side edges connected to the indoor side of the laterally adjacent face plates are placed in the groove of the main gutter. The opposing ends fixed to the convex portion and connected to the indoor side of vertically adjacent face plates are brought into contact with or connected to each other in the groove of the branch gutter, and the face plates are attached to the flange of the main gutter and the outdoor side of the side plate of the branch gutter. The outdoor side of the cover that is supported on the side, spans the opposite side edges of the laterally adjacent face plates, and covers these side edges on the outdoor side of the convex part is on the same or almost the same plane as the outdoor side of the face plate. It is placed above.

[Effect]

In the building surface structure according to the present invention, the ends of the support gutter are supported by the protrusions protruding inward in the width direction from the side walls of the main gutter, so the support gutter can be reliably maintained in a stable state without using it as a separate member. The outdoor sides of the flange of the main gutter and the side plates of the branch gutter can be easily positioned in the same or nearly coplanar line, thereby allowing the flange of the main gutter and the side plates of the branch gutter Support is also stable.

In addition, a small and lightweight face plate can be used that covers one area surrounded by the main gutter and the branch gutter, and the opposite side edge of the horizontally adjacent face plate can be used. It is fixed in the groove of the main gutter to the convex part that protrudes above the groove bottom of the main gutter, and the opposing ends of vertically adjacent face plates are brought into contact with or connected to each other in the branch gutter, so the positioning and fixing of the face plate is possible. It's easy to do.

Furthermore, since the height of the convex part protruding above the groove bottom of the main gutter is lower than the opening edge of the main gutter, the convex part extends over the opposite side edges of the laterally adjacent face plates and makes these side edges convex. The outdoor side surface of the cover that covers the outdoor side of the section can be arranged on the same or almost the same plane as the outdoor side surface of the face plate, resulting in a good appearance.

In addition, even if rainwater enters the indoor side from the side edges of the roof panels, the abutting parts of the ends, or the connecting pipes, it can be collected by the grooves of the main gutter and branch gutter and drained out of the surface structure. It can reliably prevent water from leaking into the room rather than the body.

〔Effect of the invention〕

As explained above, the present invention fixes the main gutter, which also serves as a mounting member for the face plate, vertically on the outdoor side of the support member, and fixes the end of the branch gutter horizontally between the main gutter as the main gutter. In a building surface structure in which a part of the gutter protrudes into the gutter groove and is surrounded by a main gutter and a branch gutter is covered with a single face plate, the main gutter has a width at the opening edges of both side walls. A flange that protrudes inward in the width direction, a convex portion that protrudes on the groove bottom at a height lower than the opening edge, and a protrusion that protrudes inward in the width direction from between the opening edge and the groove bottom on both side walls. a protrusion is formed along the longitudinal direction, and the protrusion of the main gutter is fixed to the support member,
The end of the branch gutter is fitted into a notch provided on the side wall opening side of the main gutter and supported by the protrusion, so that the outdoor sides of the flange of the main gutter and both side plates of the branch gutter are on the same or almost the same plane. The opposite side edges arranged on the indoor side of the horizontally adjacent face plates are fixed to the convex part in the groove of the main gutter, and the opposite side edges are arranged continuously on the indoor side of the vertically adjacent face plates. The ends abut or connect to each other within the groove of the support gutter, the face plate is supported on the flange of the main gutter and the outdoor side of the side plate of the support gutter, and the laterally adjacent face plates straddle the opposite side edges, Since the outdoor side surface of the cover that covers these side edges on the outdoor side of the convex portion is disposed on the same or almost the same plane as the outdoor side surface of the face plate, the following effects can be obtained.

That is, in the building surface structure according to the present invention, the ends of the support gutter are supported by the protrusions that protrude inward in the width direction from the side walls of the main gutter, so the support gutter can be maintained in a stable state without using it as a separate member. The outdoor sides of the flange of the main gutter and both side plates of the branch gutter can be easily positioned on the same or almost the same plane. Support for will also be stable.

In addition, a small and lightweight face plate can be used that covers one area surrounded by the main gutter and the branch gutter, and the opposite side edge of the horizontally adjacent face plate can be used. It is fixed in the groove of the main gutter to the convex part that protrudes above the groove bottom of the main gutter, and the opposing ends of vertically adjacent face plates are brought into contact with or connected to each other in the branch gutter, so the positioning and fixing of the face plate is possible. It is easy to make, has a relatively simple structure, and can be constructed with good workability.

Furthermore, since the height of the convex part protruding above the groove bottom of the main gutter is lower than the opening edge of the main gutter, the convex part extends over the opposite side edges of the laterally adjacent face plates and makes these side edges convex. The outdoor side surface of the cover that covers the outdoor side of the section can be arranged on the same or almost the same plane as the outdoor side surface of the face plate, resulting in a good appearance.

Even if rainwater enters the indoor side from the side edges, end abutments, or connections of the roof shingles, it can be caught by the main gutter and branch gutter grooves and drained out of the surface structure. It can reliably prevent water from leaking into the room rather than the body.
