SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to improve the problems. The construction and mounting of siding is not limited to one direction, and an arbitrary intermediate position can be obtained. The purpose of the present invention is to provide a prefabricated siding method that enables construction to be performed from a position and can significantly shorten the construction period.

[0004]

In order to achieve the above object, the present invention relates to a steel frame frame in which a steel frame is assembled into a frame having a predetermined size, and the end valleys of the corrugated sheet are arranged along both sides of the steel frame. Attach the corrugated sheet to the prefabricated siding and hang it at the outer wall construction position, install a predetermined gap between the connecting parts of the siding on both sides and attach it to the wall base of the skeleton, and In the gap, bend both sides in the longitudinal direction at an angle approximately equal to the valley inclination angle of the corrugated plate, and form convex protrusions in the longitudinal direction on the intermediate plane part of both bent parts. Of the corrugated sheet, projecting into the gap between the troughs of the corrugated sheet, and inserting the bent sections on both sides against the back side of the valley slope section of the corrugated sheet on both sides; Put a waterproof sealing material on the upper surface of the valley at the end of the plate and cover the convex protrusion with a groove type metal fitting with a lip, A prefabricated structure in which the outer wall siding is constructed by inserting through bolts from the top surface of the retainer into the convex protrusions on the mattress plate and passing through the gap between the connection parts of the siding on both sides and fixing the nuts on the back side of the steel frame. It features a siding method.

[0005]

As described above, since the siding is prefabricated with a predetermined size as described above, more uniform and accurate siding can be obtained as compared with siding that is pasted on site, and on-site construction can be performed efficiently. Also, connect the siding on both sides by laying the end troughs of both corrugated plates along the side edges of the steel frame instead of overlapping the end troughs of the corrugated sheet extending from the side edges of the steel frame. Since it is sandwiched with bolts and grooved metal fittings with eye plate and lip, it is not necessary to install sequentially from one direction for construction, for example, installation of siding starts from the middle position of outer wall construction for convenience of construction. Finally, a flexible construction method is possible, such as inserting the last missing siding to complete a continuous outer wall.
