〔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 intervals with the support fittings 6, 6, and The gap between the parts is closed with an elastic absorbing material 7, and the stop pieces 1a, 1a are each folded upward from the ends of the main plates 1, 1, and from both sides of the main joint plate 9 in the width direction, the longitudinal direction of the sides is Locking edges 9a, 9 on both sides of the joint plate C, with the locking edges 9a, 9a folded downward at least in part
A is inserted and locked into the locking pieces 1a, 1a on the left and right sides of the spaced part so that the area near the spaced part is covered with the joint plate C, and the widthwise sides of the joint main plate 9 and the locking edge 9a are connected to each other. A hollow part is formed by the end of the main plate 1 and the locking piece 1a, and the bent part 10 at the front end of the joint plate C is engaged with the outer engaging part 3, and the rear end is inserted into the inner engaging part 2. Firstly, the connection point can be constructed extremely watertight, secondly, the connection point can be installed easily and quickly, thirdly, the connection point can be made stronger, and fourthly, it can be used for horizontal roofing. This has the effect of being able to respond favorably to thermal expansion and contraction in the longitudinal direction of the architectural board A.

To explain these effects in detail, first, the space between the ends of the main plates 1 and 1 is closed with elastic absorbing material 7,
Furthermore, the locking pieces 1a, 1a are folded upward from the ends of the main plates 1, 1, respectively, and the locking edges 9a, 9a on both sides of the joint plate C,
9a to the locking pieces 1a, 1a on the left and right sides of the space
The joint plate C is inserted into and locked so that the vicinity of the gap is covered by the joint plate C, and a hollow part is formed by the widthwise side of the joint main plate 9, the locking edge 9a, the end of the main plate 1, and the locking piece 1a. Therefore, even if rainwater enters from the tip side of the locking edge 9a in the hollow part of the side viewed from the cross section of the connection point, it will be blocked by the locking piece 1a, and furthermore, due to the presence of the hollow part. It can prevent the capillary phenomenon of rainwater and allow the rainwater to flow down to the bottom.
A connection structure with extremely excellent watertightness can be provided.

Furthermore, in the connection point of the present invention, both sides of the elastic absorbing material 7 that closes the gap are attached to opposite ends of the main plates 1, 1 of the adjacent horizontal building boards A, A, so that the elastic absorber 7 can be freely expanded and contracted. The spaced portions are joined by the stretchable absorbent material 7, preventing rainwater from penetrating into the spaced portions, resulting in a more watertight connection structure.
Also, by inserting and locking the locking edges 9a, 9a on both sides of the joint plate C into the locking pieces 1a, 1a on the left and right sides of the above-mentioned interval, the joint plate C can be connected without coming off even in strong wind and rain. It can strengthen the parts. 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. . Also, with a joint plate C as shown in Fig. 5, the first
As shown in Fig. 3, etc., the locking edge 9a is provided over the entire length, and by locking the locking edge 9a and the locking piece 1a as a whole, it is extremely difficult for the locking edge 9a to come off, and the strength is increased. can be made excellent. Also, the bracket 6,
Since the connection point is supported by the connection point 6, it can be strengthened by preventing deformation and distortion even if someone steps on that point during work.

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 7. 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 9a of the joint plate C is folded back, even if the horizontal building board A undergoes appropriate thermal expansion and contraction and moves, the outer surface of the main plate 1 of the horizontal building board A will not be damaged. etc. can be prevented from occurring. 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, the horizontal roofing building board A can be connected in a strong and watertight manner, 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 and the expansion and contraction absorbing material 7. A major feature of the present invention is that it can be absorbed.
