Claims

[Claims for Utility Model Registration] (1) A synthetic resin ribbed hollow plate consisting of sheet-like flat plates arranged in parallel at a constant interval, with ribs extending between the two flat plates to connect the two flat plates. In,
The hollow plate opening end face crossing the extending direction of the rib is
A synthetic resin seal plate is provided with a protrusion that intersects with the end of the rib on the joint surface with the opening end surface, so that the part of the protrusion of the seal plate that intersects with the rib end of the hollow plate is A sealing structure for an opening end face of a ribbed hollow plate made of synthetic resin, characterized in that the opening end face is sealed by ultrasonic welding into a rib. (2) A sealing structure for an open end face of a synthetic resin ribbed hollow plate according to claim 1, wherein the hollow plate is a hollow plate in which ribs are vertically disposed on a sheet-like flat plate and extend in the longitudinal direction of the hollow plate. (3) A sealing structure for an open end face of a synthetic resin ribbed hollow plate according to claim 1 or 2, wherein the open end face of the hollow plate sealed by the seal plate is an open end face perpendicular to the longitudinal direction of the hollow plate. . (4) The seal plate has, on the joint surface with the opening end surface of the hollow plate, a protrusion that intersects with the end of the sheet-like flat plate that makes up the hollow plate in addition to a protrusion that intersects with the end of the rib that makes up the hollow plate. The sealing plate is also provided with a strip, and the protruding strip intersects with the end of the sheet-like flat plate,
4. A sealing structure for an open end face of a synthetic resin ribbed hollow plate according to claim 1, wherein the intersecting portion is ultrasonically welded into the sheet-like flat plate. (5) The composition according to claim 4, wherein the protrusion that intersects with the end of the sheet-like flat plate is a protrusion in which a portion of the distal end of the protrusion on the outer peripheral end side of the seal plate is notched. Seal structure for the opening end of a hollow plate with resin ribs.
