〔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. The main plates 1, 1 are placed on the base material B at appropriate intervals, and the ends of the main plates 1, 1 of the horizontal building boards A, A adjacent to each other at the intervals are supported by the brackets 6, and the main plates 1, The locking band-shaped weir bodies 7, 7 each having a locking piece 7b provided on the upper surface of the band-shaped body 7a are pasted on top of each other at one end, and from both sides of the joint main plate 8 in the width direction, the longitudinal sides of the sides are attached. Both the locking edges 8a, 8a of the joint plate C, in which the locking edges 8a, 8a are folded downward in at least a part of the direction, are connected to the locking pieces of the locking band-shaped weir bodies 7, 7 on the left and right sides of the spaced apart part. 7b, 7b and the vicinity of the gap is covered with the joint plate C, and the hollow part is formed by the widthwise side of the joint main plate 8, the locking edge 8a, the end of the main plate 1, and the locking piece 1a. , and furthermore, 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, firstly, the connection point is made extremely watertight. Second, the installation of the connection points can be done easily and quickly, and third,
Fourthly, the connecting points can be made stronger, and fourthly, the thermal expansion and contraction in the longitudinal direction of the horizontal roofing building board A can be well accommodated.

To explain these effects in detail, first, a locking piece 7b is provided on the upper surface of the strip 7a on the main plates 1 and 1 ends of the horizontal building boards A and A that are adjacent to each other at the interval. The locking band-like weir bodies 7, 7 are respectively pasted, and both locking edges 8a, 8a of the joint plate C are attached to the locking pieces 7 of the locking band-like weir bodies 7, 7 on the left and right sides of the above-mentioned interval.
b, 7b, a hollow part is formed by the widthwise side of the joint main plate 8, the locking edge 8a, the main plate 1 end and the locking piece 1a, and the widthwise side of the joint main plate 8 and the locking edge 8a form a hollow part. By forming a hollow part between the locking edge 8a, the end of the main plate 1, and the locking piece 1a, the presence of the hollow part on the side when the connection point is viewed as a cross section prevents rainwater from entering from the tip side of the locking edge 8a. Even if it is, the locking piece 7 of the strip 7a
The presence of the hollow part prevents the capillary phenomenon of rainwater and allows the rainwater to flow downward, providing a connection structure with extremely excellent watertightness. That is, the intrusion of rainwater can be reliably blocked at the space between the ends of the main plates 1 and 1. In addition, the end of the main plate 1 of the horizontal roofing architectural board A was not bent in any way, but the locking band-shaped weir body 7, which acts as a rainwater cutoff weir, was simply pasted on. It can be done easily and quickly. In addition, the locking edges 8a, 8a of the joint plate C,
By inserting and locking into the locking pieces 7b, 7b of the locking strip weir bodies 7, 7 on the left and right sides of the above-mentioned interval, the joint plate C will not come off even in strong wind and rain, and the connection point can be strengthened. . In particular, if only a part of the joint plate C as shown in Fig. 6 has a locking structure as shown in Fig. 7, insertion and locking can be performed efficiently and work performance can be improved. . Further, in a joint plate C as shown in FIG. 5, a locking edge 8a is provided over the entire length as shown in FIGS. 1, 3, etc.
By completely locking the locking piece 7b with the locking piece 7b, it is difficult for the locking piece to come off, and it can be made stronger. Furthermore, since the connection point is supported by the receiving metal fitting 6, deformation and strain etc. do not occur even when a worker stands on it during work, and the structure can be made strong.

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 The construction board A can absorb the thermal expansion and contraction that occurs in response to the outside temperature in the longitudinal direction at the intervals between its connection points, and in particular, the joint plate C and the bracket 6 can absorb the thermal expansion and contraction that occurs in response to the outside temperature in the longitudinal direction. Because it is not fixed to the edge of the side-roofing building board A and is free, the heat will also be applied to the left and right side side-roofing building boards A, A, and even the entire side-roofing envelope. No stress is generated, and in particular, the main plate 1 of the horizontal roofing architectural board A exposed on the outer surface can be made to have almost no deformation strain or the like. 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 outside of the main plate 1 of the horizontal building board A will not be removed. It can prevent scratches etc. from occurring on the surface. This makes it possible to create a strong connection structure that hardly experiences deformation or strain even when subjected to external forces such as earthquakes, and prevents the reduction in strength caused by conventional strain and the plate cracking phenomenon. .

As described above, it is possible to make a strong and watertight connection, and at the same time, the horizontal roofing building board A can absorb thermal expansion and contraction corresponding to the outside temperature in the longitudinal direction at the intervals between the connection points, Furthermore, the present invention has a great advantage in that it has a simple structure and can be constructed at low cost.

In addition, the locking piece 7b of the locking band-shaped weir body 7 is
If it is made of a metal plate that is a separate member from the strip 7a, it can slide more smoothly in response to the thermal expansion and contraction of the horizontal building board A.
