特開２００２−７０２９０号公報 特開２００１−３４８９８６号公報 特開平７−１３９１２９号公報 In order to reduce the influence of weight and lightweight floor impact sound as a conventional floor structure of an apartment house, for example, the inventions of JP 2002-70290 A, JP 2001-348986 A, and JP 7-139129 A are disclosed. Has been. These are all intended to reduce the influence of weight and light floor impact sound by supporting the floor board using the support legs.
JP 2002-70290 A JP 2001-348986 A JP 7-139129 A

しかし、上記の床構造は、いずれも床板を支持する支持脚でレベル調整をするため、レベル調整が簡単にできず床の構築に手間がかかるという問題があった。   However, all of the above floor structures have a problem that the level adjustment is not easy because the level is adjusted by the supporting legs that support the floor board, and it takes time to construct the floor.

本発明はこれらの問題に鑑みてなされたものであり、その目的は、床板のレベル調整が簡単にでき、かつ重量および軽量床衝撃音の影響を少なくすることができる床構造およびその構築方法を提供することである。   The present invention has been made in view of these problems, and an object of the present invention is to provide a floor structure capable of easily adjusting the level of a floor board and reducing the influence of weight and light floor impact sound, and a construction method thereof. Is to provide.

し、該下床上に仕上材を敷き詰めることを特徴とする。 In the floor structure for solving the above-described problems, an additional striking layer having an appropriate thickness is formed on the upper surface of the concrete slab, and a large number of dumpling-shaped unevenness adjusting materials are installed on the striking layer. Ri Na a number of the underfloor member is laid closely on the adjustment member, it is that the lower portion of the uneven surface adjustment member is buried in increasing droplet layer.
In addition, the floor structure is constructed by forming a striking layer in an appropriate range on the upper surface of the concrete slab, and installing a large number of dumpling-like land-fitting conditioners thereon before the striking layer is dried. After the floor base material is installed on the adjustment material, this process is sequentially repeated to form a lower floor by closely spreading the floor base material, and then laying the finishing material on the lower floor.

不陸調整材に連続した増打層を介して床下地材を設置したことにより、スラブ厚が大きくなったので、重量および軽量床衝撃音を効果的に吸収することができるとともに、いわゆる太鼓現象という、共振現象を防ぐことができる。また不陸調整材の下部が増打層に埋没したことにより、コンクリートスラブとの接着が容易になるとともに、不陸調整も簡単にできる。また増打層とコンクリートスラブとでスラブ厚を形成することにより、不陸調整材と一体になった増打層がスラブの増打ち効果となって、重量および軽量床衝撃音の影響を少なくすることができる。また流動性を有する増打層と不陸調整材とを介して床下地材を設置したことにより、レベル調整が簡単かつ迅速で、精度良く行える。   By installing the floor base material through a continuous striking layer on the non-land surface adjustment material, the slab thickness has increased, so it is possible to effectively absorb the weight and light floor impact sound and the so-called drum phenomenon That is, the resonance phenomenon can be prevented. Further, since the lower part of the unevenness adjusting material is buried in the striking layer, adhesion with the concrete slab is facilitated and unevenness adjustment can be easily performed. In addition, by forming a slab thickness between the striking layer and the concrete slab, the striking layer that is integrated with the unevenness adjusting material becomes a striking effect of the slab, reducing the influence of weight and light floor impact sound. be able to. In addition, by installing the floor base material via the additional striking layer having fluidity and the unevenness adjusting material, level adjustment can be performed easily, quickly and accurately.

以下、本発明の床構造およびその構築方法の実施の形態を図面に基づいて説明する。また各実施の形態において同じ構成は同じ符号を付して説明し、異なった構成にのみ異なった符号を付して説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a floor structure and a construction method thereof according to the present invention will be described with reference to the drawings. In the embodiments, the same components are described with the same reference numerals, and only different components are described with different reference numerals.

図１および図２は床構造１を示す断面図および平面図である。この床構造１は既存建物のコンクリートスラブ２の上面にモルタルなどで適宜厚さの増打層３が形成され、この増打層３の上に団子状の不陸調整材４が設置され、この不陸調整材４の上に床下地材５が密接して設置されて下床６が形成され、該下床６に仕上材７が敷き詰められて構成されている。   1 and 2 are a cross-sectional view and a plan view showing the floor structure 1. FIG. In this floor structure 1, an additional striking layer 3 having an appropriate thickness is formed on the upper surface of a concrete slab 2 of an existing building with a mortar or the like, and a dumpling-shaped unevenness adjusting material 4 is installed on the striking layer 3. A floor base material 5 is closely placed on the non-land surface adjusting material 4 to form a lower floor 6, and a finishing material 7 is spread on the lower floor 6.

不陸調整材４は増打層３と同じモルタルであり、団子状の下部が増打層３に埋没されて一体となり、この埋没によりレベル調整および不陸調整が行われている。また増打層３と不陸調整材４とが一体になって、コンクリートスラブ２とでスラブ厚を形成するので、増打層３がスラブの増打ち効果になる。   The unevenness adjusting material 4 is the same mortar as the additional striking layer 3, and the dumpling-shaped lower part is buried in the striking layer 3 to be integrated, and level adjustment and unevenness adjustment are performed by this embedding. Further, since the striking layer 3 and the unevenness adjusting material 4 are integrated to form a slab thickness with the concrete slab 2, the striking layer 3 provides a slab increasing effect.

床下地材５は発泡樹脂複合体であり、ポリスチレン系樹脂やポリオレフィン系樹脂、ウレタンなどの発泡樹脂からなる下部材８と、この下部材８の上面に設置された硬質熱可塑性発泡樹脂の桟木９とから構成され、この桟木９に仕上材７が釘１０で固定されている。   The floor base material 5 is a foamed resin composite, and includes a lower member 8 made of a foamed resin such as a polystyrene resin, a polyolefin resin, or urethane, and a pier 9 of a hard thermoplastic foamed resin installed on the upper surface of the lower member 8. The finishing material 7 is fixed to the pier 9 with nails 10.

なお、上記の床構造１は既存建物のコンクリートスラブ２であったが、これは既存建物に限らず、新築建物のコンクリートスラブであってもよい。   In addition, although said floor structure 1 was the concrete slab 2 of the existing building, this may not be an existing building but the concrete slab of a new building.

次に、床構造の構築方法について説明する。はじめに、図３に示すように、コンクリートスラブ２の上面にプライマーなどの接着剤を塗布した後、この接着剤の上に適宜厚さのモルタルを塗って増打層３を形成する。この増打層３は、例えば一列目の床下地材５を設置する箇所にのみ形成する。   Next, a method for constructing the floor structure will be described. First, as shown in FIG. 3, an adhesive such as a primer is applied to the upper surface of the concrete slab 2, and then a mortar with an appropriate thickness is applied on the adhesive to form the striking layer 3. For example, the additional striking layer 3 is formed only at a place where the first-layer floor base material 5 is installed.

次に、図４に示すように、この増打層３が乾燥する前に、この上にモルタルで団子状の不陸調整材４を多数設置し、この不陸調整材４の上に床下地材５を設置する。そして、部屋内周に設置した際根太１１の上面を基準線として、床下地材５を下側に押し込むと、不陸調整材４の上部が押し潰されるとともに、その下部が増打層３に埋没して一体となり、不陸とレベルとの調整ができる。   Next, as shown in FIG. 4, before the additional striking layer 3 dries, a large number of mortar dumpling-like conditioners 4 are installed thereon, and the floor foundation is placed on the irregularity conditioner 4. Material 5 is installed. Then, when the floor base material 5 is pushed downward with the upper surface of the joist 11 as the reference line when installed on the inner periphery of the room, the upper portion of the unevenness adjusting material 4 is crushed, and the lower portion thereof becomes the additional striking layer 3 It is buried and united, and can adjust the unevenness and level.

次に、１列目の床下地材５を設置した後、図５に示すように、２列目の床下地材を設置する箇所にモルタルを塗って２列目の増打層３を形成する。そして、上記と同じ方法で床下地材５を設置するとともに、この工程を順次繰り返すことによって、コンクリートスラブ２の全面に床下地材５を密接して下床６を形成する。そして、この下床６上に仕上材７を敷き詰めて床構造１を構築する。   Next, after the first row of the floor base material 5 is installed, as shown in FIG. 5, mortar is applied to the place where the second row of the floor base material is installed to form the second row of striking layers 3. . And while installing the floor base material 5 by the same method as the above, the floor base material 5 is brought into close contact with the entire surface of the concrete slab 2 by sequentially repeating this process to form the lower floor 6. Then, the floor structure 1 is constructed by spreading the finishing material 7 on the lower floor 6.

なお、床下地材５は一列ずつ設置したが、一列ずつに限らず、二列または三列などの複数列ずつ設置することもでき、増打層３も複数列の範囲に形成することができる。さらに、列単位ではなく、１個ずつ床下地材５を設置することもでき、１個ずつ設置するための箇所に増打層３を形成することもできる。   In addition, although the floor base material 5 was installed one row at a time, it is not limited to one row but can be installed in a plurality of rows such as two rows or three rows, and the striking layer 3 can be formed in a range of a plurality of rows. . Furthermore, the floor base material 5 can be installed one by one, not in units of rows, and the additional striking layer 3 can be formed at a location for installing one by one.

このようにコンクリートスラブ２の増打層３に不陸調整材４を介して床下地材５を設置する工程を繰り返すことにより、床下地材５を簡単に敷き詰めることができ、しかも不陸およびレベルの調整も簡単にできるので、床構造１を簡単に構築することができる。   In this way, by repeating the process of installing the floor base material 5 on the additional striking layer 3 of the concrete slab 2 via the non-land surface adjusting material 4, the floor base material 5 can be easily spread, and the unevenness and level Therefore, the floor structure 1 can be easily constructed.
