The upper waterproofing material 9 of the upper joint board to which the above-mentioned upper joint board is attached should be installed so that it can slide as appropriate while holding the main boards 1. By engaging the bent part 10 at the front end of the two-part joint plate with the upper part 3 and inserting the rear end into the lower part 2, firstly, the connection point can be constructed in an extremely simple manner. Second, installation of the connection points can be done easily and quickly, and third, it can respond well to thermal expansion and contraction in the longitudinal direction of the architectural board A for horizontal roofing. play.

To explain the function and effect in detail, first, the lower waterproofing material 7.7 of the lower joint board C and the upper waterproofing material 9 of the upper joint board are adjacent to each other at a distance from each other.

Since the ends of the main plates 1 and 1 are clamped, rainwater does not enter between the ends of the main plates 1 and 1 at the connection point of the horizontal roofing enclosure and the upper joint main plate 8, resulting in extremely watertightness. It is possible to provide a flexible connection structure.

In addition, in particular, in the present invention, the main plate 1.1 end of the building boards A and A for the horizontal beams are placed on the lower joint plate C, and the upper joint plate is placed at the connecting interval. By simply locking the bent portion 10 of the upper joint plate in this way, the connection point can be constructed, and there is a great advantage that not only is the construction extremely simple, but the construction can be performed simply and quickly. moreover,
Since the connection point is supported by the lower joint plate C, it can be strengthened by preventing deformation and distortion even if someone steps on that point during work.

Furthermore, at the connection point, the lower waterproof material 7 of the lower joint plate C.
7 and the upper waterproofing material 9 of the upper joint iD are arranged so that they can slide as appropriate while holding the ends of the main plates 1.1 of the building boards A and A for the horizontal beams adjacent to each other at the interval, Even if the architectural board A for the horizontal roofing is made of a material with a high degree of expansion and contraction (WL, etc.), or even if the temperature difference in the area where the architectural board A for the horizontal roofing is installed is large, the architectural board for the horizontal roofing Thermal expansion and contraction that occurs in the plate in response to the outside temperature in the longitudinal direction can be absorbed by the above-mentioned sliding, and especially in the lower joint main plate 6 of the lower joint plate C.
The upper joint main plate 8 of the upper joint board is not fixed to the edge of the building board A for horizontal beams on either side of the interval, and is free, so that the building boards for horizontal beams on the left and right sides. Board A, A
Furthermore, no 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 H building board exposed 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 also possible to prevent the conventional deterioration in strength due to strain generation and the plate ringing phenomenon.

As described above, while the lower waterproofing material 7 and the upper waterproofing material 9 are configured to sandwich the end of the main plate 1 to ensure good watertightness, the lower waterproofing material 7 and the upper waterproofing material 9 are connected to the lower joint main plate. 6 and the upper joint main plate 8, the lower waterproof material 7 and the upper waterproof material 9 can be made to have excellent weather resistance while increasing the strength of the connection point. A major feature of the present invention is that it can maintain good watertightness over a long period of time. Furthermore, even with an extremely simple configuration, it is possible to connect watertightly, and at the same time, the architectural board A for the horizontal beams can be thermally expanded and contracted in response to the outside temperature in the longitudinal direction to the sandwiching part of the sliding connection point. There is also a big advantage that it can be absorbed.

In addition, if the folded edges 8a, 8a are folded downward on both sides of the upper joint main plate 8 of the upper joint board, even if the horizontal construction board is moved by heat expansion and contraction in the horizontal direction, the horizontal It is possible to prevent damage to the outer surface of the main board 1 to the architectural board for rods, and furthermore, even if rainwater enters through the folded edges 8a, 8a, the folded edges 8a and the upper waterproof material 9 A hollow part is formed in between, and the capillary phenomenon of rainwater can be prevented in the hollow part, thereby achieving even better water tightness.
