FLOOR MATERIAL AND FLOOR STRUCTURE USING FLOOR MATERIAL

MATSUOKA NAOTO / HAMADA MAKOTO

To provide a floor material capable of making a span between large beams long where floor plates can be installed free from deflection without small beams, in a wooden building utilizing CLT, and to provide a floor structure using the floor material.SOLUTION: A floor material 2 includes: an upper plate 3 having a rectangular plate surface; a lower plate 4 having a rectangular plate surface; one end part connection member 5; and the other end part connection member 6. The upper plate 3 and the lower plate 4 are formed by an orthogonal collection plate, and the one end part connection member 5 and the other end part connection member 6 are formed by an orthogonal collection plate or a collection plate. The upper plate 3 and the lower plate 4 are arranged so that a plate surface which is a lower surface 31 of the upper plate 3 and a plate surface which is an upper surface 41 of the lower plate 4 oppose to each other with an interval. One long side end part of the upper plate 3 and one long side end part of the lower plate 4 are connected by the one end part connection member 5, and the other long side end part of the upper plate 3 and the other long side end part of the lower plate 4 are connected by the other end part connection member 6.SELECTED DRAWING: Figure 2

【課題】ＣＬＴを活用した木造建築物において、小梁無しでたわみが生じないように床板を設置可能な大梁間のスパンを長くできる床材、及び、当該床材を用いた床構造を提供する。【解決手段】本発明に係る床材２は、長方形の板面を有した上板３と、長方形の板面を有した下板４と、一方端部連結部材５と、他方端部連結部材６とを備え、上板３及び下板４が直交集成板により形成されるとともに、一方端部連結部材５及び他方端部連結部材６が直交集成板又は集成材により形成され、上板３の下面３１となる板面と下板４の上面４１となる板面とが間隔を隔てて対向するように上板３と下板４とが配置され、上板３の一方の長辺側端部と下板４の一方の長辺側端部とが一方端部連結部材５により連結され、上板３の他方の長辺側端部と下板４の他方の長辺側端部とが他方端部連結部材６により連結されたことを特徴とする。【選択図】図２
