〔Effect of the invention〕

In the present invention, a construction board A for horizontal roofing having an appropriate length in the longitudinal direction is formed with an inner engaging part 2 on one side of the main plate 1 and an outer engaging part 3 on the other side. Arrange them on the base material B at appropriate intervals, and support the main plates 1, 1 ends of the horizontal construction boards A, A adjacent to each other at the interval points with the support fittings 5, 5. The gaps between the parts are filled with elastic absorbing material 6, and folded edges 1a, 1a are formed above the ends of the main plates 1, 1, respectively, and folded edges 8a, 8a are formed below both sides of the joint main plate 8 in the width direction. The vicinity of the gap is covered with the joint plate C formed with the above, and an appropriate gap is provided between the opposing folded edges 1a, 1a, and the gap is filled with bar-shaped sealing materials 11, 11, respectively. By engaging the bent part 9 at the front end of the joint plate C with the outer engaging part 3 and inserting the rear end into the inner engaging part 2, the first connection point can be constructed in an extremely watertight manner, Secondly, the installation work at the connection point can be done easily and quickly, and thirdly, it can cope well with thermal expansion and contraction in the longitudinal direction of the horizontal roofing building board A.

To explain these effects in detail, first, the gap between the ends of the main plates 1 and 1 is closed with elastic absorbing material 6,
Furthermore, the folded edges 1a, 1a are each folded upward from the ends of the main plates 1, 1, and the vicinity of the gap is covered with the joint plate C, and the opposing folded edges 1a, 1
Since an appropriate gap was provided between the ends a, the sides of the connection point when viewed in cross section include the widthwise side of the joint main plate 8 of the joint plate C, the folded edge 8a, the end of the main plate 1, and the folded edge 1a. A hollow part is formed, and its folded edge 8
Even if rainwater enters from the tip side of a, it is blocked by the rod-shaped sealant 11, and furthermore, the presence of the hollow part prevents capillary action of rainwater, providing a connection structure with extremely excellent watertightness. can. Furthermore, in the connection point of the present invention, both sides of the elastic absorbing material 6 that closes the gap are connected to the adjacent building boards A and A for horizontal roofing.
Since it is attached to opposite ends of the main plates 1, 1, the space between them is joined by the stretchable absorbent material 6, which prevents rainwater from penetrating into the space, resulting in a more watertight connection structure. can. As described above, even if the folded edge 1a is processed on site, the connection plate C can be attached by simply inserting the bent portion 9, which is relatively simple and quick. Further, since the connection point is supported by the receiving fittings 5, 5, even if someone steps on the connection point during work, deformation and strain can be prevented and the connection point can be strengthened.

Furthermore, even if the horizontal roofing building board A is made of a highly elastic material (such as copper), or even if there is a large temperature difference in the area where the horizontal roofing building board A is installed, the horizontal roofing Thermal expansion and contraction of construction board A that occurs in response to the outside temperature in the longitudinal direction can be absorbed by the spacing between the connection points and the expansion/contraction absorbing material 6. Because it is not fixed to the edge of the horizontal roofing building board A on either side and is free, the left and right horizontal roofing building boards A, A
Furthermore, no thermal stress is generated in the entire horizontal roofing enclosure, and in particular, almost no deformation strain or the like occurs in the main plate 1 of the horizontal roofing architectural board A exposed on the outer surface. In addition, since the locking edge 8a of the joint plate C is folded downward, even if the horizontal building board A moves due to appropriate thermal expansion and contraction, the main plate 1 of the horizontal building board A will not move. It is possible to prevent scratches etc. from occurring on the outer surface. This makes it possible to create a strong connection structure in which almost no deformation strain occurs even when subjected to external forces such as earthquakes, and it is possible to prevent the conventional reduction in strength due to strain generation and the plate rattling phenomenon.

As mentioned above, while being able to connect watertightly,
A major feature of the present invention is that the horizontal construction board A can absorb thermal expansion and contraction corresponding to the outside temperature in the longitudinal direction at the spacing between the connection points and the expansion and contraction absorbing material 6.
