Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat roof having a structure in which elongated roof plates are spread in parallel and both longitudinal edges of each roof plate are fixed by connecting devices.

[0002]

2. Description of the Related Art A flat roof of this kind is provided with receiving groove grooves at predetermined intervals in a lower ground structure of the roof, for example, a base plate or a heat insulating layer formed on the base plate in such a manner that the receiving groove grooves are formed in the groove. Each of the connecting members is fitted with an elongated connecting member, and each of the connecting members is provided with a holding portion for holding a side edge portion of the roof plate on both sides thereof, thereby sequentially holding and fixing the roof plate stretched on the base surface. It is configured like.

As the above-mentioned connecting member, for example, an actual fair 6-
As disclosed in Japanese Patent No. 15101, a structure in which side edges of a roof plate are horizontally inserted into fitting grooves integrally provided on both sides of a connecting member.
As disclosed in JP-A-65789 and JP-A-1-61325, a receiving member having a dish-shaped cross section in which a connecting member is fixed in the receiving groove, and a holding member accommodated in the receiving member, And an engaging member that engages with this holding member,
The holding member has an engaging groove formed at the center thereof, and flat portions are formed on both sides of the engaging groove so that the side edges of the adjacent roof plates are placed on the flat portions. The engaging member includes a leg piece engaged with the engaging groove and has a pressing portion facing the flat portion, and when the leg piece is engaged with the engaging groove. The pressing portion is configured to press and fix the side edge portion of the roof plate to the flat portion.

[0004]

In the conventional flat roof described above, in which the connecting member is provided with the fitting groove, the connecting member may be integrally molded and fixed in the receiving groove, so that the structure is simple. Moreover, since the holding force of the side edges of the roof plate in the plate thickness direction is large, there is an advantage that the roof plate is highly fixed and peeling of the roof plate can be prevented, but the roof plates cannot be individually removed. Therefore, there is a problem that it is not possible to replace each roof plate individually, and since the connecting member is already fixed in the receiving groove, the position of the connecting member is moved according to the width of the roof plate. Since it is not possible to do so, there is also a problem that if the width of two adjacent roof plates is different, the work of spreading the roof plates becomes extremely difficult.

Further, in the case where the connecting member is composed of a receiving member, a holding member and an engaging member, the holding member can be moved within the receiving member and the engaging member can be attached to and detached from the holding member. Since the roof plate can be individually attached to and detached from the connecting member, even if there is a difference in the width of the adjacent roof plate, this can be adjusted and absorbed by moving the holding member, and the roof plate can be individually replaced. Although there is an advantage that it can be done, since the fastening force of the fastening member to the holding member is not sufficient, if a strong peeling force acts on the roof plate during a typhoon, the side edge of the roof plate is peeled off from the holding member. There is a problem that it will end up.
