Zusammenfassung:PROBLEM TO BE SOLVED: To provide a technology for enhancing sound insulation performance without increasing a floor height, specifically a dry double floor structure with a floor panel that has the floor panel installed stably without the adjacent floor panels contacting each other, and also provide a construction method of the dry double floor structure and a connecting material used with the dry double floor structure.SOLUTION: A dry double floor structure of the present invention includes a foundation slab, a support leg, a floor joist, a floor panel, and a connecting material. The floor joist includes at least a thin plate-form top plate, and the connecting material is installed between the adjacent floor panels. The connecting material has a housing hole for housing the support leg and a protrusion protruding toward the floor panel side. A recess is formed on an edge surface of the floor panel. A connecting space is formed by laying out the adjacent floor panels with a gap in between, and the connecting material is installed in the connecting space. Here, the protrusion of the connecting material is inserted into the recess of the floor panel.SELECTED DRAWING: Figure 1 【課題】本願発明の課題は、床高を大きくすることなく遮音性能を高める技術の提供であって、床パネルを設けた床構造とし、しかも隣接する床パネルどうしが接触することなく連結されるとともに、確実に安定するよう床パネルが設置された乾式二重床構造、その乾式二重床構造の構築方法、及び乾式二重床構造に用いられる連結材を提供することである。【解決手段】本願発明の乾式二重床構造は、基礎スラブと、支持脚、根太、床パネル、連結材を備えた構造である。根太は少なくとも薄板状の頂板を有するものであり、連結材は隣接する床パネル間に設置される。この連結材は、支持脚を収容する収容孔と床パネル側に突出する突起部を有している。また床パネルの端部面には凹部が設けられ、隣接する床パネルが隙間を設けて配置されることで接続空間が形成され、この接続空間に連結材が設置される。このとき、連結材の突起部が床パネルの凹部に挿入される。【選択図】図1
