[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a roof panel in which a plurality of support members having a posture along a slope direction of a roof are installed side by side in the slope direction, and the roof members are juxtaposed to the support members in a lateral direction perpendicular to the slope direction. A drain groove for placing and supporting the opposite ends of two roof plates facing each other in the lateral direction, receiving the water from between the opposite ends of the roof plates, and guiding the water downward along the gradient direction. And a communicating means for guiding water to flow downward from a drain groove of an upper support member located above the gradient direction to a drain groove of a lower support member located below the gradient direction among support members adjacent to each other in the gradient direction. The present invention relates to a roof structure and a connecting member in the roof structure.

[0002]

2. Description of the Related Art In the above-mentioned roof structure, a roof having a large length in a gradient direction can be formed. As such a roof structure, conventionally, as shown in FIG. Communication means for guiding water to flow down from the drain groove 6a of the upper support member 6 to the drain groove 6a of the lower support member 6 by filling the sealing material 22 between the opposing end surfaces of the drain groove forming portion 6B in the above. Was composed.

[0003]

However, in the case of the above-mentioned prior art, the filling of the sealing material is inadequate, etc.
If there is a gap due to poor adhesion between the sealing material and the end face of the drainage groove forming part, a water leakage accident will occur, and if the inner surface of the sealing material is uneven, water will accumulate. There is a drawback in that it requires special skill and poor workability. An object of the present invention is to provide a roof structure that can be constructed with good workability and a useful connecting member.

[0004]

The characteristic feature of the roof structure according to the present invention is that the communicating means comprises a gutter-like shape, which is provided at one end with the lower end of the drainage groove forming portion of the upper support member. Fit and connect with the outer surface overlapping, and
At the other end, a connection member made of an elastic resin is provided to fit into the drain groove of the lower support member.

A first characteristic configuration of the connecting member according to the present invention is that the connecting member is formed in a gutter shape from an elastic resin and overlaps with the lower surface of the drainage groove forming portion of the upper support member in the roof structure so as to overlap the outer surface thereof. At one end has a fitting connection portion for fitting connection, and at the other end a fitting portion for fitting into the drainage groove of the lower support member in the roof structure. is there.

A second characteristic configuration of the connection member according to the present invention is that a projection is formed on an inner surface of a connection portion for fitting to the upper support member.

A third characteristic configuration of the connecting member according to the present invention is that an insertion portion is provided to be inserted into the lower support member from the upper end side of the drain groove forming portion.

[0008]

According to the roof structure of the present invention, the water flowing down in the drainage groove of the upper support member is received by the connecting member connected to the drainage groove forming portion of the support member and flows down. It reaches the inside of the drain of the support member. Then, the connection member is fitted and connected to the lower end of the drainage groove forming portion of the upper support member in a state of overlapping with the outer surface thereof, and the upper end of the connection member is positioned above the lower side of the drainage groove formation portion. Therefore, even if there is a gap between the connecting member and the drainage groove forming portion, it is necessary to climb over the upper end of the connecting member in order for the water entering the gap to leak around the lower end of the drainage groove forming portion and leak outside. Water does not leak through the gap. Moreover, the connection member is fitted into the drain groove of the lower support member, and the upper end of the drain groove forming portion of the lower support member is located above the lower end of the connection member. In addition, even if there is a gap between the connecting member and the drainage groove forming portion, it is necessary to climb over the upper end of the drainage groove forming portion in order for the water entering the gap to leak around the lower end of the connecting member and leak out to the outside, No water leaks through the gap. In other words, while connecting the drain grooves of the adjacent support members in a state where there is no water leakage, there is no need to bond the connection member to the drain groove forming portion of the support member, and it is only necessary to fit them.

According to the first characteristic configuration of the connecting member of the present invention, the fitting connecting portion is fitted and connected to the drain groove forming portion of the upper support member, and the drainage groove of the lower supporting member is inserted into the drain groove. By simply fitting the fitting portions, the drain grooves of the vertically adjacent support members can be connected in a state where there is no water leakage.

According to the second characteristic configuration of the connecting member according to the present invention, the protrusion prevents the fitting connection portion from adhering to the drain groove forming portion, and a gap with the drain groove forming portion can be secured.
Movement of water in the gap due to capillary action, that is, water leakage through the gap can be reliably prevented.

According to the third characteristic configuration of the connecting member according to the present invention, the connecting member can be held by the supporting member by inserting the drainage groove forming portion of the lower supporting member into the insertion portion. Before installing the member, the connecting member can be pre-attached to the support member.

[0012]

Therefore, according to the present invention, it is possible to provide a roof structure which can easily and surely connect the drainage grooves of the supporting members which are adjacent in the gradient direction and which can be constructed with good workability. Reached.

Further, it has become possible to provide a connecting member which excels in workability, a connecting member which excels in workability and water leakage prevention, and a connecting member which can further improve workability by reducing work in high places. .
