Abstract: A waterproof structure which does not require use of fixing tools, suppresses swelling and is easily installed. A waterproof structure provided with a waterproof sheet, which is laid on a part of a target region of a foundation that is a flat site, and a waterproof coating film, which is formed on at least a part of a peripheral region. The waterproof sheet has a resin sheet containing a poly(vinyl chloride)-based resin and an adhesive layer which is provided on one side of the resin sheet and which is bonded to the foundation. The adhesive layer is provided on a partial region of the resin sheet. The waterproof coating film contains a polyurethane-based resin and is provided so as to be in contact with the resin sheet on at least a surface of a rim part of the waterproof sheet.

Abstract: An underlay cushioning sheet that is arranged on the surface of a foundation and that has a waterproof coating film formed thereon. The underlay cushioning sheet includes a cushioning layer having an overlay surface and a curing acceleration layer having a coating film formation surface on the opposite side from the overlay surface. A waterproof coating film including a polyurethane resin is formed on the coating film formation surface of the curing acceleration layer by applying a one pack-type liquid waterproofing material. The curing acceleration layer includes a reactive material capable of reacting with the liquid waterproofing material. The reactive material either (1) includes a functional group capable of reacting with an isocyanate included in the liquid waterproofing material or (2) reacts with a latent curing agent included in the liquid waterproofing material and generates a functional group capable of reacting with the components of the liquid waterproofing material.

Abstract: A fixed roller is laterally axially supported by a movable body so as to ow an axial center line of the fixed roller to extend in parallel to a lateral direction, and driven to rotate an upper peripheral surface of the fixed roller backward, and a plurality of split press rollers respectively having the axes inclined by a predetermined angle with respect to an axial center line of the fixed roller as viewed in plan are arranged in a row in a lateral direction above the fixed roller in the manner of supporting the split press rollers by press roller frames. The split press rollers are energized to the descending side by oil-hydraulic cylinders respectively provided between a frame of the body and the press roller frames so as to bring the lower peripheral surface side of each split press roller into contact with the upper peripheral surface of the fixed roller under the action of pressure.
