Description
本発明は、下地上に接着剤を用いることなく、置敷きにより容易に着脱可能に表面材を施工することができ、しかも表面材は下地上に接着剤が無くともズレ等を生ずることなくしっかりと固定できる下地の施工方法及び施工体に関する。 In the present invention, the surface material can be easily detachable by placing without using an adhesive on the base, and the surface material can be firmly fixed without causing any deviation even if there is no adhesive on the base. It is related with the construction method and construction body of the foundation which can be fixed.
従来、置敷型床タイルの施工方法としては例えば固定板とそれから上部に突出した突起部をもつ滑止具を、床板ないし床下地に固定したのち、前記滑止具の突起部を置敷型床タイルの裏面に貫入させることを特徴とする置敷型床タイルの敷設方法が知られている（例えば、特許文献１参照）。 Conventionally, as a method for constructing a floor tile, for example, after fixing a non-slip device having a fixed plate and a protrusion protruding upward from the fixed plate to a floor board or a floor base, the protrusion of the non-slip device is mounted on the floor tile. There is known a method of laying floor tiles that penetrates the back surface of the floor (see, for example, Patent Document 1).
しかしこの方法では釘状、刃状の突起部を床タイルの裏面に貫入すると記載されており、容易に着脱することができない。
また接着剤を用いずに着脱可能で且つ防滑性を有する敷物として、裏面にループ構造を有する敷物本体と、片面に該敷物本体の裏面のループ構造と係合するフック構造を有し、もう一方の面に粘着剤層を有する面ファスナーテープとからなる敷物が知られている（例えば、特許文献２参照）。しかしこの方法ではループとフックで係合するためコストが高く、当初はループとフックの係合力は強いため着脱がかなり困難である一方、経時的に該係合力が弱くなり耐久性がないという欠点を有する。
However, this method describes that a nail-like or blade-like protrusion is inserted into the back surface of the floor tile and cannot be easily attached or detached.
Further, as a rug that can be attached and detached without using an adhesive and has slip resistance, a rug main body having a loop structure on the back surface and a hook structure that engages with the loop structure on the back surface of the rug main body on one side, A rug comprising a surface fastener tape having an adhesive layer on its surface is known (see, for example, Patent Document 2). However, this method is costly because it is engaged with the loop and the hook, and initially, the engagement force between the loop and the hook is strong, so that it is quite difficult to attach and detach. On the other hand, the engagement force becomes weak over time and there is no durability. Have
さらに接着剤を不要とした置敷きにより床仕上げ材を載置する床仕上げ工法として、表面に植毛を施した既設床材上に、該植毛面と相対する面に植毛を施した床仕上げ材を置敷くことを特徴とする建物の床仕上げ工法が知られている（例えば、特許文献３参照）。この方法においては、既設床材とこの上に載置する床仕上げ材の相対する面双方に施された植毛の作用は、双方の面上において垂直方向に起毛された毛が絡み合うことにより、接着剤や係止部材のような格別な固定手段を講じなくても、床仕上げ材が横方向にずれるのを防止することができると記載されているが、双方の植毛が弾力的に接触することにより、既設床材と床仕上げ材が密着せず、植毛同士の弾力的な接触では床仕上げ材の固定の程度は十分ではない。 Furthermore, as a floor finishing method for placing floor finishing materials by laying without the need for adhesives, floor finishing materials with flocking on the surface opposite to the flocked surface on the existing flooring with flocking on the surface There has been known a floor finishing method for buildings characterized by laying (see, for example, Patent Document 3). In this method, the action of flocking applied to both the existing floor material and the opposite surface of the floor finishing material placed thereon is bonded to each other by tangling the hair raised in the vertical direction on both surfaces. Although it is described that it is possible to prevent the floor finish from shifting laterally without taking special fixing means such as agents and locking members, both flocks should be in elastic contact. Therefore, the existing flooring and the floor finishing material do not adhere to each other, and the degree of fixing of the floor finishing material is not sufficient in the elastic contact between the flocks.
本発明の課題は接着剤を用いることなく施工するにも拘わらず、容易に着脱可能で、且つコストが安く、耐久性に優れ、しかも表面材を下地上にしっかりと固定できる表面材を下地上に施工する方法及び施工体を提供することにある。 The object of the present invention is to provide a surface material on the substrate that can be easily attached and detached, is inexpensive, has excellent durability, and can firmly fix the surface material on the substrate in spite of construction without using an adhesive. It is in providing the method and construction body to construct.
