Title:
EDGE CUTTING JOINT MATERIAL, AND JOINT STRUCTURE THEREOF
Document Type and Number:
Japanese Patent JP2018044405
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an edge cutting joint material 10 on a wall balustrade 2 that follows expansion/contraction of concrete C without being peeled off from the concrete.SOLUTION: An edge cutting joint material 10 comprises a foamed PE base material 11, an elastic resin (EPDM) layer 12 provided on both plate surfaces of the base material 11, and a calcium carbonate-mixed resin adhesive layer 13 on a side surface of the elastic resin layer 12. The edge cutting joint material may serve as a mold for the joint, because the base material 11 ensures shape retention property. When concrete C is cast, calcium carbonate forms an inorganic bond with the concrete C before solidification, and is joined firmly. As such, the elastic resin layer 12 expands/contracts when the concrete C expands/contracts, and absorbs the expansion/contraction of the concrete C. Therefore, the joint material 10 does not come off (is not peeled off) from the concrete C.SELECTED DRAWING: Figure 2
