Description

本発明は、複数のベース部材が連結されることにより、ベース部材の上面に取り付けられた平面視略四角形の床化粧材が隣同士で目地隙間を形成して床面に敷設される床材の敷設構造に関する。   The present invention relates to a flooring material in which a plurality of base members are connected to each other so that a floor covering material having a substantially rectangular shape in plan view attached to the upper surface of the base member forms a joint gap next to each other and is laid on the floor surface. It relates to the laying structure.

従来、バルコニー、ベランダ、テラス及び屋上などのコンクリート床には、複数の床タイルが隣同士で目地隙間を形成するように敷設されている。床タイルの敷設において、目地隙間は、部材間に2〜8mm程度の幅であけられる継ぎ目であり、床タイルの熱膨張による挙動を緩和し、割り付け誤差を吸収し、下方への排水を促し、意匠性を向上させるために必要となる。しかし、目地隙間を設けることは、床タイルを正確な位置に割り付けたり、目地隙間を微調整したりするなど、熟練した技能が必要となるため、作業員の確保、作業の効率化、作業時間の短縮などを困難なものにしている。   Conventionally, a plurality of floor tiles are laid on concrete floors such as balconies, verandas, terraces, and rooftops so as to form joint gaps next to each other. In laying the floor tile, the joint gap is a joint that is opened with a width of about 2 to 8 mm between the members, relaxes the behavior due to the thermal expansion of the floor tile, absorbs the allocation error, and promotes drainage downward, Necessary for improving the design. However, providing joint spaces requires skilled skills such as assigning floor tiles to the correct position and fine-tuning the joint spaces, thus securing workers, improving work efficiency, and working time. It is difficult to shorten the time.

そこで、近年、敷設作業が容易な床タイルユニットが普及し、作業の効率化や、作業時間の短縮化が図られている。即ち、床タイルユニットは、隣接するベース部材の間に連結部材を介在させることにより、ベース部材の上面に取り付けられた床タイルの間に目地隙間が形成される。その結果、作業者は、熟練した技能を要することなく、床タイルの間に見栄えの良い目地隙間を形成させて床タイルを効率良く敷設することができる。   Therefore, in recent years, floor tile units that can be easily laid have become widespread, and work efficiency and work time have been shortened. That is, in the floor tile unit, a joint member is interposed between adjacent base members, so that a joint gap is formed between the floor tiles attached to the upper surface of the base member. As a result, the operator can efficiently lay the floor tiles by forming a good-looking joint gap between the floor tiles without requiring skill.

このような床タイルユニットの普及に伴い、床タイルの連結についての工夫が多数提案されている(例えば、特許文献1及び特許文献2)。   With the widespread use of such floor tile units, many ideas for connecting floor tiles have been proposed (for example, Patent Document 1 and Patent Document 2).

特開2010−53552号公報JP 2010-53552 A 特開2002−206329号公報JP 2002-206329 A

しかしながら、特許文献1に記載された敷設構造にあっては、床タイルの目地隙間から下方のベース部材が露出しているため、火災時の炎や、煙草の火種などが目地隙間から侵入してベース部材を延焼させるおそれがある。特に、ベース部材は、加工が容易であることと、コンクリート床に対する傷を防ぐこととから、合成樹脂製であることが多く、炎や火種により燃焼しやすい。また、市場では、建築物に対する安全性が着目されており、建築基準法の認定を受けた床材の敷設構造が望まれている。しかし、従来の敷設構造では、ベース部材が燃焼しやすいため、認証を受けることが難しく、市場のニーズに応えることができない。   However, in the laying structure described in Patent Document 1, since the lower base member is exposed from the joint gap of the floor tile, a flame at the time of fire, a fire type of cigarette, and the like have entered from the joint gap. There is a risk of spreading the base member. In particular, the base member is often made of synthetic resin because it is easy to process and prevents scratches on the concrete floor, and is easily burned by flames or fire types. Also, in the market, safety for buildings is attracting attention, and a flooring laying structure that is certified by the Building Standards Act is desired. However, in the conventional laying structure, since the base member is easy to burn, it is difficult to receive certification and cannot meet market needs.

また、特許文献2に記載された敷設構造にあっては、目地隙間側に張り出した係合部を嵌め合うことにより、目地隙間を隠して床材を連結するようにしている。しかし、床材を一枚一枚取り外すことができないため、例えば、破損した床材を部分的に交換することができない、など作業性に問題がある。   Moreover, in the laying structure described in Patent Document 2, the floor space is concealed and the flooring is connected by fitting the engaging portions protruding to the joint gap side. However, since the floor materials cannot be removed one by one, there is a problem in workability, for example, a damaged floor material cannot be partially replaced.

本発明はかかる事情を鑑みてなされたものであり、ベース部材の間に、不燃材料からなる、上方に突出する突条部を有する短手方向断面略凸形状の連結部材を介在し、この突条部をベース部材の上面に取り付けられた床化粧材の間に形成された目地隙間に嵌め込むようにしてベース部材を連結させることにより、目地隙間から露出するベース部材を外部から遮断するとともに、床化粧材の敷設作業を容易にすることができる床材の敷設構造を提供することを目的とする。   The present invention has been made in view of such circumstances, and a connecting member made of a non-combustible material and having a projecting ridge portion protruding upward is interposed between the base members. The base member exposed from the joint gap is blocked from the outside by connecting the base member so that the strip is fitted into the joint gap formed between the floor decorative materials attached to the upper surface of the base member, and the floor makeup An object of the present invention is to provide a floor laying structure capable of facilitating the laying work of the material.

本発明に係る床材の敷設構造は、複数のベース部材が連結されることにより、該ベース部材の上面に取り付けられた平面視略四角形の床化粧材が隣同士で目地隙間を形成して床面に敷設される床材の敷設構造において、複数の前記ベース部材は、その間に、不燃材料からなる、上方に突出する突条部を有する短手方向断面略凸形状の連結部材が介在され、前記突条部が前記目地隙間に嵌り込むように連結されることを特徴とする。   The floor covering laying structure according to the present invention has a structure in which a plurality of base members are connected to each other so that a floor covering material having a substantially rectangular shape in plan view attached to the upper surface of the base member forms a joint gap next to each other. In the laying structure of the flooring laid on the surface, a plurality of the base members are interposed between the connecting members having a substantially convex shape in the short direction cross section having a protruding ridge portion made of an incombustible material. The ridges are connected so as to fit into the joint gaps.

本発明に係る床材の敷設構造にあっては、ベース部材の間に、不燃材料からなる、上方に突出する突条部を有する短手方向断面略凸形状の連結部材を介在することにより、隣り合うベース部材の上面に取り付けられた床化粧材の間に目地隙間を形成させる。また、形成された目地隙間に連結部材の突条部を嵌め込むことにより、目地隙間から露出するベース部材を外部から遮断し、炎や火種などの侵入を防ぐ。   In the laying structure of the flooring according to the present invention, by interposing a connecting member having a substantially convex shape in the short-side cross section having a protruding portion protruding upward, made of a non-combustible material, between the base members, A joint gap is formed between the floor decorative materials attached to the upper surfaces of the adjacent base members. Further, by fitting the protrusions of the connecting member into the formed joint gap, the base member exposed from the joint gap is blocked from the outside, and intrusion of flames, fire types, and the like is prevented.

更にまた、本発明に係る床材の敷設構造は、前記ベース部材は、上面に複数の前記床化粧材が取り付けられる場合、隣接する前記床化粧材の隙間から露出する前記上面の部分が、不燃材料からなる保護材によって隠されるようにしてある構成であってもよい。   Furthermore, in the flooring laying structure according to the present invention, when a plurality of the floor decorative materials are attached to the upper surface of the base member, the portion of the upper surface exposed from the gap between the adjacent floor decorative materials is nonflammable. It may be configured to be hidden by a protective material made of a material.

本発明に係る床材の敷設構造にあっては、ベース部材の上面に複数の床化粧材が取り付けられる場合、隣接する床化粧材の隙間から露出するベース部材の上面部分を不燃材料からなる保護材によって覆い隠すことにより、床化粧材の隙間から露出するベース部材の上面部分を外部から遮断し、炎や火種などの侵入を防ぐ。   In the floor covering laying structure according to the present invention, when a plurality of floor decorative materials are attached to the upper surface of the base member, the upper surface portion of the base member exposed from the gap between adjacent floor decorative materials is made of a non-combustible material. By covering with the material, the upper surface portion of the base member exposed from the gaps in the floor decorative material is blocked from the outside, and intrusion of flames, fire types, and the like is prevented.

本発明にあっては、従来の床タイルユニットによる敷設作業の容易性を確保しつつ、目地隙間から露出するベース部材を外部から遮断して炎や火種の浸入を防ぐことができ、安全性の高い製品が求められている市場のニーズに応えることができる。   In the present invention, while ensuring the ease of laying work by the conventional floor tile unit, the base member exposed from the joint gap can be blocked from the outside to prevent intrusion of flames and fire types, It can meet the needs of the market where high products are required.

実施の形態1.
本発明に係る床材の敷設構造について、実施の形態を示す図面に基づいて以下説明する。床材の敷設構造は、図1に示すように、平面視略四角形の床化粧材1と、床化粧材1を下から支持するベース部材2と、複数のベース部材2を連結するための連結部材3とを備える。
Embodiment 1 FIG.
A flooring laying structure according to the present invention will be described below with reference to the drawings showing embodiments. As shown in FIG. 1, the flooring laying structure has a substantially square floor decorative material 1 in plan view, a base member 2 that supports the floor decorative material 1 from below, and a connection for connecting a plurality of base members 2. And a member 3.

床化粧材1は、不燃材料で形成されている。不燃材料は、建築基準法で定める技術的基準に適合する不燃性を持つ材料であり、陶磁器質、石、ガラス、コンクリートなどの材料が含まれる。特に、陶磁器質は、耐熱性、耐候性に優れ、変色や変形が少ないため、床化粧材1の材料として好ましい。   The floor decorative material 1 is formed of a noncombustible material. The non-combustible material is a material having non-combustibility that meets the technical standards defined by the Building Standard Law, and includes materials such as ceramics, stone, glass, and concrete. In particular, porcelain is excellent as a material for the floor decorative material 1 because it is excellent in heat resistance and weather resistance and has little discoloration or deformation.

また、床化粧材1は、平面視四角形のタイル状に形成され、床上面となる表面10と、表面10の周縁から垂下する端面11と、ベース部材2と対向する裏面12とを備える。表面10は、水に濡れても滑ることがないように細かな凹凸が付けられており、無地、様々な模様又は色彩が付されている。また、表面10から端面11にかけての周縁部分は、不陸などでの床化粧材1の角浮きをなくし、躓きを防ぐため、面取りがなされている(図示せず)。また、端面11は、敷設された際、隣接する別の床化粧材1の側面11との間に目地隙間4を形成する。   Further, the floor decorative material 1 is formed in a square tile shape in plan view, and includes a surface 10 that is a floor upper surface, an end surface 11 that hangs down from the periphery of the surface 10, and a back surface 12 that faces the base member 2. The surface 10 has fine irregularities so that it does not slip even when wet, and is plain and has various patterns or colors. Moreover, the peripheral part from the surface 10 to the end surface 11 is chamfered (not shown) in order to eliminate the corner floating of the floor decorative material 1 due to unevenness or the like, and to prevent rolling. Further, when the end surface 11 is laid, a joint gap 4 is formed between the side surface 11 of another adjacent floor decorative material 1.

ベース部材2は、ポリエチレン、ポリプロピレンなどの合成樹脂で形成されている。ベース部材2は、床化粧材1を取り付けるための取付面20と、取付面20の周縁から垂下する端面21と、底面22と、底面22から下方に突出する脚部23とを備える。取付面20は、ベース部材2の上面であり、床化粧材1と平面視で同形同大となるように形成され、床化粧材1が取り付けられる。端面21は、連結された際、隣接する別のベース部材2の端面21との間に目地隙間4を形成する。底面22は、床上面を歩く歩行者が帯電しないように一面にカーボン繊維が貼り付けられている。脚部23は、底面22から複数突出し、ベース部材2の周縁より僅かに内側寄りであり、且つ、この周縁に沿うように所定の間隔をあけて底面22から下方に突出している。なお、本発明において、床化粧材1の間に形成された目地隙間と、ベース部材2の間に形成された目地隙間とは、連続して一体的なものとして捉えており、区別することなく「目地隙間4」と表す。   The base member 2 is formed of a synthetic resin such as polyethylene or polypropylene. The base member 2 includes an attachment surface 20 for attaching the floor decorative material 1, an end surface 21 depending from the periphery of the attachment surface 20, a bottom surface 22, and a leg portion 23 that protrudes downward from the bottom surface 22. The mounting surface 20 is the upper surface of the base member 2 and is formed to have the same shape and size as the floor decorative material 1 in plan view, and the floor decorative material 1 is attached thereto. When the end face 21 is connected, a joint gap 4 is formed between the end face 21 and the end face 21 of another adjacent base member 2. Carbon fiber is affixed to the bottom surface 22 so that a pedestrian walking on the floor top surface is not charged. A plurality of leg portions 23 protrude from the bottom surface 22, slightly inward from the periphery of the base member 2, and protrude downward from the bottom surface 22 with a predetermined interval along the periphery. In the present invention, the joint gap formed between the floor decorative materials 1 and the joint gap formed between the base members 2 are regarded as a continuous and integral one, and are not distinguished. This is expressed as “joint gap 4”.

連結部材3は、上述する床化粧材1と同様に不燃材料で形成されている。不燃材料は、建築基準法で定める技術的基準に適合する不燃性を持つ材料である。連結部材3は、上面30と、上面30から突出する突条部31と、上面30に形成された複数の取付孔32と、底面33とを備える。連結部材3は、平面視L字状、平面視I字状など、様々な形態に形成されたものが準備されているが、実施の形態1では、平面視L字状の連結部材3を一例として説明する。   The connecting member 3 is formed of a non-combustible material, similar to the floor decorative material 1 described above. The non-combustible material is a material having non-combustibility that meets the technical standards defined by the Building Standard Law. The connecting member 3 includes an upper surface 30, a protrusion 31 protruding from the upper surface 30, a plurality of attachment holes 32 formed in the upper surface 30, and a bottom surface 33. The connecting member 3 is prepared in various forms such as an L shape in plan view and an I shape in plan view. In the first embodiment, the connecting member 3 having an L shape in plan view is taken as an example. Will be described.

突条部31は、上面30の平面視短手方向中央位置から垂直に立ち上がり、その立ち上がりが上面30の平面視長手方向に沿って連続することによりレール状をなしている。また、突条部31は、平面視L字状をなす上面30に沿って2方向に形成されたレール状となっており、この2本のレールが上面30のコーナ部付近で交わって十字状をなしている。また、突条部31は、図1に示すように、その高さ寸法Aが少なくともベース部材2の厚み寸法B以上となるように形成されている。また、突条部31は、その幅寸法(図示せず)が目地隙間4にぴたりと嵌り込む寸法となるように形成されている。また、連結部材3は、突条部31を備えることにより、平面視短手方向に沿って切断したときの側面視断面形状が略凸形状となる。   The protruding portion 31 rises vertically from the center position in the short side direction of the top surface of the upper surface 30 and forms a rail shape by continuing the rising along the longitudinal direction of the upper surface 30 in the plan view. Further, the protruding portion 31 has a rail shape formed in two directions along the upper surface 30 having an L shape in plan view, and the two rails intersect in the vicinity of the corner portion of the upper surface 30 to form a cross shape. I am doing. Further, as shown in FIG. 1, the protrusion 31 is formed such that its height dimension A is at least equal to or greater than the thickness dimension B of the base member 2. Further, the protrusion 31 is formed such that its width dimension (not shown) fits into the joint gap 4 exactly. Moreover, the connection member 3 is provided with the protruding portion 31 so that the cross-sectional shape in a side view when cut along the lateral direction in the plan view is a substantially convex shape.

取付孔32は、以下のように形成されている(図3参照)。取付孔32は、平面視長手方向に寸法Cの間隔をあけて複数形成されている。また、複数の取付孔32は、突条部31を挟むようにして平行に形成され、平行する間隔が寸法Dとなっている。また、複数の取付孔32は、上面30のコーナ部付近において、十字状をなす突条部31に仕切られるように寸法Eの間隔をあけて形成されている。また、複数の取付孔32は、上面30の平面視長手方向の端からコーナ部寄りに寸法Fの間隔をあけて形成されている。また、複数の取付孔32は、上面30のコーナ角から内側寄りに寸法Gの間隔をあけて形成されている。なお、寸法Cと、寸法Dと、寸法Eと、寸法Fと寸法Gとの合計寸法とは、4つとも同じ値となるように形成されている。   The attachment hole 32 is formed as follows (see FIG. 3). A plurality of the attachment holes 32 are formed at intervals of a dimension C in the longitudinal direction in plan view. Further, the plurality of mounting holes 32 are formed in parallel so as to sandwich the protrusion 31, and the parallel interval is the dimension D. Further, the plurality of mounting holes 32 are formed at intervals of a dimension E so as to be partitioned by a cross-shaped protrusion 31 in the vicinity of the corner portion of the upper surface 30. Further, the plurality of mounting holes 32 are formed at an interval of a dimension F from the end of the upper surface 30 in the longitudinal direction in plan view toward the corner portion. Further, the plurality of mounting holes 32 are formed with an interval of a dimension G inward from the corner angle of the upper surface 30. In addition, the dimension C, the dimension D, the dimension E, and the total dimension of the dimension F and the dimension G are formed so that all four may have the same value.

また、連結部材3は、全体が以下のように形成されている。連結部材3は、長手方向の長さ寸法Hが床化粧材1の一辺の長さと等しくなるに形成されている。また、連結部材3は、その厚みがベース部材2の脚部23の高さ寸法以上となるように形成されている。   Moreover, the whole connection member 3 is formed as follows. The connecting member 3 is formed such that the length dimension H in the longitudinal direction is equal to the length of one side of the floor decorative material 1. Further, the connecting member 3 is formed so that its thickness is equal to or greater than the height of the leg portion 23 of the base member 2.

このように、床材の敷設構造は、複数の部材により構成されている。以下、これらの部材を用いた床材の敷設方法について説明する。   Thus, the flooring laying structure is composed of a plurality of members. Hereinafter, a method for laying a flooring using these members will be described.

(床材の組み立て)
ベース部材2は、取付面20に接着剤が塗布され、この取付面20に一枚の床化粧材1が貼り付けられる。このとき、床化粧材1は、端面11がベース部材2の端面21と揃うように取り付けられる。ベース部材2は、床化粧材1が取り付けられることにより、取付面20が床化粧材1によって覆い隠される一方、取付面20以外の部分(例えば端面21など)が露出した状態となる。
(Assembling flooring)
In the base member 2, an adhesive is applied to the mounting surface 20, and the single floor decorative material 1 is attached to the mounting surface 20. At this time, the floor decorative material 1 is attached so that the end surface 11 is aligned with the end surface 21 of the base member 2. When the floor decorative material 1 is attached to the base member 2, the attachment surface 20 is covered with the floor decorative material 1, while a portion other than the attachment surface 20 (for example, the end surface 21) is exposed.

(床材の敷設)
連結部材3は、図3に示すように、コンクリート床上に規則正しく配置され、隣接する別の連結部材3とで、突条部31により囲まれた平面視四角形状の凹空間を形成する。ベース部材2は、図2に示すように、床化粧材1が取り付けられた状態で連結部材3の凹空間に導かれ、脚部23が連結部材3の凹空間内に存在する取付孔32にそれぞれ挿入される。このとき、ベース部材2は、全ての脚部23が一つの連結部材3の取付孔32に挿入されるのでなく、連結部材3の上面30のコーナ部から離れた位置にある脚部23については、隣接する別の連結部材3の取付孔32に挿入されることとなる。ベース部材2は、全体が連結部材3の凹空間にぴたりと嵌り込む。
(Laying flooring)
As shown in FIG. 3, the connecting member 3 is regularly arranged on the concrete floor, and forms a concave space with a rectangular shape in plan view surrounded by the protruding portion 31 with another adjacent connecting member 3. As shown in FIG. 2, the base member 2 is guided to the recessed space of the connecting member 3 in a state where the floor decorative material 1 is attached, and the leg portion 23 is inserted into the mounting hole 32 existing in the recessed space of the connecting member 3. Each inserted. At this time, in the base member 2, not all the leg portions 23 are inserted into the mounting holes 32 of the one connecting member 3, but the leg portions 23 located at a position away from the corner portion of the upper surface 30 of the connecting member 3. Then, it is inserted into the mounting hole 32 of another adjacent connecting member 3. The base member 2 fits perfectly into the concave space of the connecting member 3 as a whole.

そして、同様の作業を繰り返すことにより、床化粧材1がコンクリート床全体に敷きつめられたとき、ベース部材2は、コンクリート床に規則正しく配置された状態で連結部材3により連結固定される。また、ベース部材2は、図6に示すように、端面21が、隣接する別のベース部材2の端面21と対向して目地隙間4を形成し、この目地隙間4に連結部材3の突条部31が嵌り込み、少なくとも端面21が突条部31により隠される。また、隣接する4つのベース部材2(図示せず)は、間に十字状の目地隙間4を形成し、この目地隙間4に、連結部材3の上面30のコーナ部付近において十字状をなす突条部31が嵌り込む。なお、コンクリート床のレイアウトの関係から、目地隙間4に連結部材3の突条部31が嵌り込んでいない部分については、突条部31の代わりとなる部材(図示せず)を目地隙間4に嵌め込むことにより調整する。   Then, by repeating the same operation, when the floor decorative material 1 is spread over the entire concrete floor, the base member 2 is connected and fixed by the connecting member 3 in a state of being regularly arranged on the concrete floor. In addition, as shown in FIG. 6, the end surface 21 of the base member 2 faces the end surface 21 of another adjacent base member 2 to form a joint gap 4, and the protrusion of the connecting member 3 is formed in the joint gap 4. The portion 31 is fitted, and at least the end surface 21 is hidden by the protruding portion 31. Four adjacent base members 2 (not shown) form a cross joint gap 4 between them, and the joint gap 4 has a cross-shaped protrusion in the vicinity of the corner portion of the upper surface 30 of the connecting member 3. The strip 31 is fitted. In addition, from the relation of the layout of the concrete floor, a member (not shown) instead of the ridge portion 31 is used as the joint gap 4 for a portion where the ridge portion 31 of the connecting member 3 is not fitted in the joint gap 4. Adjust by fitting.

床材の敷設構造は、上述する方法で敷設されることにより、以下の作用効果を奏する。ベース部材2は、コンクリート床に規則正しく配置された連結部材3によって位置が規制されることにより、コンクリート床上に規則正しく敷設される。また、ベース部材2に取り付けられた床化粧材1が規則正しく敷設される。また、目地隙間4が少なくとも床化粧材1の間で規則正しく形成される。その結果、床材の敷設作業が容易となる。   The laying structure of the flooring has the following effects by being laid by the method described above. The base member 2 is regularly laid on the concrete floor by the position of the base member 2 being regulated by the connecting members 3 regularly arranged on the concrete floor. Further, the floor decorative material 1 attached to the base member 2 is laid regularly. Further, the joint gaps 4 are regularly formed at least between the floor decorative materials 1. As a result, the flooring work is facilitated.

また、目地隙間4に連結部材3の突条部31が嵌り込むことにより、目地隙間4から露出するベース部材2が外部から遮断され、延焼に弱いベース部材2を炎や火種から守る。その結果、床材の敷設構造として安全性が向上する。   Moreover, when the protrusion 31 of the connecting member 3 is fitted into the joint gap 4, the base member 2 exposed from the joint gap 4 is blocked from the outside, and the base member 2 that is vulnerable to fire spread is protected from flames and fire types. As a result, safety is improved as a flooring laying structure.

また、ベース部材2の脚部23を、接着剤を用いることなく、連結部材3の取付孔32に挿入するようにしていることから、脚部23を取付孔32から上方に引き抜くだけでベース部材2を取り外すことができる。
また、連結部材3を不燃性且つ弾性素材にすることにより、床化粧材1の熱膨張による挙動が緩和される。
また、連結部材3の各部分の寸法Cと、寸法Dと、寸法Eと、FとGとの合計寸法とを等しい関係にしてあることにより、少なくとも、図3に示すように連結部材3が配置された場合、連結部材3により連結されたベース部材2及び床化粧材1が隙間なく敷設される。
また、ベース部材2は、2つの連結部材3を跨ぐようにして脚部23が取付孔32に挿入されることにより、連結部材3が互いの位置がずれることがないように固定される。
