Structure and method for floor-surface covering

Abstract

To effectively improve the durability against polishing of a floor sheet by placing a seal part having an improved material and shape on the periphery of edges of the floor sheet bonded to a floor surface. A floor-surface covering structure, comprising: a floor of a building; a floor sheet having an outside size smaller than the size of the floor surface, bonded to the surface of the floor (floor surface); and a seal part that is placed along the edge of the floor sheet and set to the edge and the floor surface, wherein: a material of the seal part is an epoxy resin or a polyester resin, and the seal part has a width that is substantially uniform when viewed is a direction vertical to the floor surface.

What is claimed is:  
     
         1 . A floor-surface covering structure, comprising: a floor of a building; a floor sheet having an outside size smaller than the size of the floor surface, bonded to the surface of the floor (floor surface); and a seal part that is placed along the edge of the floor sheet and set to the edge and the floor surface, 
 wherein: a material of the seal part is an epoxy resin or a polyester resin, and    the seal part has a width that is substantially constant when viewed in a direction vertical to the floor surface.    
     
     
         2 . The floor-surface covering structure according to  claim 1 , wherein the seal part has a cross-section, cut by a face vertical to the floor surface, having a tapered shape in which the height from the floor face is made smaller from the edge of the floor sheet toward the edge of the seal part.  
     
     
         3 . The floor-surface covering structure according to  claim 1 , wherein the seal part is made from a resin composition containing an epoxy resin and a polyhydric mercaptan curing agent.  
     
     
         4 . A floor-surface covering method comprising the steps of: (i) bonding a floor sheet to a floor surface, the floor sheet having an outside size smaller than the size of the floor surface; and (ii) forming a seal part along the edge of the floor sheet, the seal part being set to the edge and the floor surface, 
 wherein: a material of the seal part is an epoxy resin or a polyester resin, and    the seal part has a width that is substantially constant when viewed in a direction vertical to the floor surface.    
     
     
         5 . A floor-surface covering method comprising the steps of: 
 (i) bonding a floor sheet to a floor surface, the floor sheet having an outside size smaller than the size of the floor surface;    (ii) placing a masking tape thinner than the floor sheet on the floor surface with a predetermined space from the edge of the floor sheet;    (iii) coating the floor surface between the edge of the floor sheet and the masking tape with a resin composition containing an epoxy resin or a polyester resin;    (iv) curing the resin composition so as to form the seal part; and    (v) removing the masking tape.
