INSTALLATION METHOD OF FLOOR MATERIAL

PROBLEM TO BE SOLVED: To provide an installation method of a floor material for easily executing engaging work of mutual tongue parts, and enhancing joining force of the mutual floor materials on the lower ground.SOLUTION: Respective tongue parts in both end parts comprise a projection part of projecting to the side and a return part of extending so as to fold back at an engaging space between the projection part and itself from the tip of the projection part, and are formed in a hook shape of being engageable so that the return part is mutually fitted to the other engaging space, and at least one among the tongue parts joins mutual floor materials by engaging the mutual tongue parts while deforming an elastic material part of the return part, by mutually pressing by vertically opposing the mutual return parts, by applying a hardener to the elastic material part of the return part on joining of the mutual floor materials, on both floor materials mutually joined on the lower ground, by forming the return part of an elastic material.SELECTED DRAWING: Figure 1 【課題】実部同士の係合作業がしやすく、かつ下地上での床材同士の接合力を高められる床材の設置方法を提供する。【解決手段】両端部における各実部は、側方に突出した突出部と、突出部の先端より、突出部との間に係合空所を隔てて折り返すように延びた返し部とを有し、相互に返し部が他方の係合空所に嵌合するようにして係合できる鉤形状とされており、実部のうちの少なくとも一方は、返し部が弾性材で形成されており、下地上において相互に接合される両床材について、床材同士の接合に係る返し部の弾性材部分に硬化剤を塗布し、返し部同士を上下に向き合わせて相互に押圧して、返し部の弾性材部分を変形させながら、実部同士を係合させて床材同士を接合する。【選択図】図１
