〔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. are arranged on the base material B at appropriate intervals, and a plurality of bulging strips 7a, 7a, ... are provided on the backing main plate 7,
A piece to be locked 8 is fixed between the adjacent bulging strips 7a, 7a, and folded edges 7b, 7b are formed above both sides in the width direction to form a backing plate C. so as to close the lower surface of the area between the edges of the main plates 1, 1 of the adjacent horizontal building boards A, A at the interval, and form folded edges 11a, 11a on the lower side of both sides of the joint main plate 11 in the width direction. and the joint main plate 1
1. The locking piece 12 of the joint plate D is arranged so as to cover the space between the joint plate D and the locking piece 12 provided on the lower surface of the joint plate D.
was locked to the locked piece 8 of the backing plate C, the bent part 13 of the front end of the joint plate D was engaged with the outer engaging part 3, and the rear end was inserted into the inner engaging part 2. As a result, firstly, the connection can be installed extremely easily and quickly, secondly, the connection can be made stronger, thirdly, the connection can be installed extremely watertight, and fourthly, the connection can be installed very easily and quickly. It has the effect of being able to cope well with thermal expansion and contraction in the longitudinal direction of the architectural board A for roofing.

To explain these effects in detail, first, the locking piece 12 of the joint plate D is connected to the locked piece 8 of the backing plate C.
A joint connection in which the backing plate C and the joint plate D sandwich the area between the edges of the main plates 1 and 1 of the adjacent horizontal building boards A and A while covering the joint part by locking the joint part. Construction is extremely simple and quick, and the locking structure prevents the joint plate D from coming off even in strong wind and rain, making the connection point strong. In particular, in the present invention, since the locking construction is simple, only a small amount of force is required for locking, which makes it extremely efficient and can improve the work efficiency of the entire horizontal roof enclosure. can. Furthermore, since the connection point is supported by the backing plate C, it can be strengthened by preventing deformation and distortion even if the connection point is stepped on during work or the like.

Also, when looking at the connection point as a cross section, even if rainwater intrudes from the edges of the main plates 1, 1 into the space between them, the backing main plate 7 has a plurality of bulging strips 7a, 7.
a, ..., and has folded edges 7b, 7b formed above both sides in the width direction.The water can flow down to a hidden gutter-like part called a backing plate C, and can be made to flow out from the underwater side to the outside, which is extremely simple. With this configuration, a connection structure with excellent watertightness can be provided.

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 that occurs in response to the outside temperature in the longitudinal direction of the construction board A can be absorbed by the presence of the spacing points at the connection points, and in particular, the joint plate D Since the side building boards A for horizontal roofing are not fixed to the ends and are free, thermal stress is applied to the left and right side building boards A, A, and even the entire horizontal roofing envelope. 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. In addition, since the folded edge 11a of the joint plate D is folded back,
Even if the architectural board A for horizontal roofing is appropriately thermally expanded and contracted and moved, scratches etc. can be prevented from occurring on the outer surface of the main board 1 of the architectural board A for horizontal roofing. By doing the above, it is 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 decrease in strength due to the generation of strain and the plate ringing phenomenon.

As described above, it is possible to make a strong and watertight connection, and at the same time, it is possible to absorb the thermal expansion and contraction corresponding to the outside temperature in the longitudinal direction of the horizontal building board A at the intervals between the connection points. The great advantage of the present invention is that these structures are extremely simple, and can be connected simply and quickly, and can be done at low cost.
