Description
【0001】[0001]
本考案はコンクリート下地に接着剤を介して直貼りする木質の床板に関する。 The present invention relates to a wooden floorboard that is directly attached to a concrete substrate with an adhesive.
【0002】[0002]
コンクリート下地に直接木質の床板を貼り込むと、コンクリートから発散する 水分や周囲の湿度によって床板に狂いが発生する。その狂いを解消するため、本 願出願人は昭和60年実第192103号(コンクリート直貼用床材成形品)の 先行技術を提供している。該技術は繊維板を上下から木材単板で挟持積層した長 尺床材成形品であって、繊維板により保湿性を保ち、裏面の横溝と縦方向の接合 間に形成される溝によって囲まれる小面積単位の収縮、膨張により床面全体に狂 いを発現させないようにし、かつ小面積の四周に接着剤を充填して床面との接着 強度を増強するものである。しかし、フローリング相互の縦、横方向の凹凸嵌合 による接合部への接着剤の侵入による接合強度の増強と、該増強による上面側合 わせ面の狂いの抑制技術に関しては未解決であった。 If a wooden floorboard is directly attached to the concrete base, the floorboard will be distorted due to moisture emanating from the concrete and ambient humidity. In order to solve the problem, the applicant of the present invention has provided the prior art of No. 192103, 1985 (molded floor material for direct cementing). The technology is a long floor molding formed by sandwiching and laminating fiberboard from above and below with wood veneers. The fiberboard maintains moisture retention and is surrounded by a groove formed between the lateral groove on the back surface and the vertical joint. The shrinkage and expansion of a small area unit prevent the entire floor surface from being deformed, and the four areas of the small area are filled with an adhesive to enhance the adhesive strength with the floor surface. However, there is an unsolved problem regarding the enhancement of the bonding strength due to the intrusion of the adhesive into the joint due to the concave and convex fitting of the flooring to each other in the vertical and horizontal directions, and the technology for suppressing the deviation of the upper surface-side mating surface due to the enhancement.
【0003】[0003]
本考案は床板貼り込み時に、接着剤が凹凸嵌合の接合部に浸入して床板相互の 接合強度を増強し、上面側合わせ面の呼吸による狂いを極力抑制できるコンクリ ート直貼用床板を提供するものである。 The present invention provides a floor board for direct concrete adhesion, in which when the floor board is attached, the adhesive penetrates into the joints of the concave and convex fittings to enhance the joint strength between the floor boards and to suppress the deviation of the upper mating surface due to breathing as much as possible. It is provided.
【0004】[0004]
本考案のコンクリート直貼用床板は、所要の長尺平板の板体の一側面と一端面 とに厚さ方向中央部に凸部を続けて突設し、他側面と他端面とに凸部に嵌着する 凹部を続けて凹設し、板体の裏面では縁部に適宜な切込み段差部を欠設するとと もに、緩衝材を貼着し、該緩衝材から板体に及んで長手方向に、所要のピッチで 多数個の横溝を横設して成る床板において、前記切込み段差部を凸部配設周縁側 に欠設するとともに、切込み段差部が凸部の底面に達する深さと所要幅を有し、 横溝が一側の凹部の内底面から他側の凸部の底面に達する深さで掘設されて成る ものである。 The floorboard for direct concrete adhering of the present invention is such that one side surface and one end surface of a required long flat plate are continuously provided with a protruding portion in the central portion in the thickness direction, and the other side surface and the other end surface are provided with protruding portions. The recessed part that is to be fitted to the plate body is continuously formed, and on the back surface of the plate body, an appropriate cut step is formed at the edge part, and at the same time, a cushioning material is adhered and In a floorboard with a large number of lateral grooves provided at a required pitch in the same direction, the cut step portion is not provided on the peripheral edge side of the convex portion, and the depth at which the cut step portion reaches the bottom surface of the convex portion is required. It has a width, and the lateral groove is dug to a depth reaching from the inner bottom surface of the concave portion on one side to the bottom surface of the convex portion on the other side.
【0005】[0005]
上記床板の構成によれば、床板の貼り込み時に、切込み段差部に充填される接 着剤が床板相互の両側面と前後端面とを接着するとともに、横溝を介して凹部と 凸部の底面から、嵌合により形成される凹部の溝底と凸部先端間の空間に接着剤 を浸入させる。 According to the above construction of the floorboard, when the floorboard is stuck, the adhesive filled in the cut step portion adheres both side surfaces of the floorboard to each other and the front and rear end surfaces, and from the bottom surface of the concave portion and the convex portion via the lateral groove. , The adhesive is allowed to penetrate into the space between the groove bottom of the recess formed by fitting and the tip of the projection.
【0006】[0006]
本考案の一実施例を説明すると、図1、図2に示すように、厚さ13mm、幅7 5mm、長さ600mm或いは900mmの無垢材から成る長尺平板の板体1の周側面 では、長手方向の一側面と一端面とに凸部2を続けて突設し、他側面と他端面と に凸部2に嵌着する凹部3を続けて凹設している。板体1の裏面では、凸部2の 裏面側の突出根部5から板体に約1.5mm食い込んで、すなわち、凸部2の表面 側の根部4よりも深く食い込んで切込み段差部6を欠設し、該部6を除く裏面全 面に2mm厚の緩衝材7を貼着し、図2、3に示すように、緩衝材7及び凸部2、 凹部3にまで及んで所要のピッチ(75mm)で幅1.5mmの横溝8を、その深さ は緩衝材7の上面より凹部3に達し、さらに凸部2の裏面側の底面に達する溝9 を掘設して成っている。切込み段差部6は凹部2の裏面側においても切り欠き設 けることができる。 An embodiment of the present invention will be described. As shown in FIGS. 1 and 2, on the peripheral side surface of a plate body 1 of a long flat plate made of a solid material having a thickness of 13 mm, a width of 75 mm and a length of 600 mm or 900 mm, A convex portion 2 is continuously provided on one side surface and one end surface in the longitudinal direction, and a concave portion 3 fitted to the convex portion 2 is continuously provided on the other side surface and the other end surface. On the back surface of the plate body 1, the protruding step portion 5 on the back surface side of the convex portion 2 cuts into the plate body by about 1.5 mm, that is, it penetrates deeper than the root portion 4 on the front surface side of the convex portion 2, and the cut step portion 6 is missing. The cushioning material 7 having a thickness of 2 mm is attached to the entire rear surface except the portion 6, and as shown in FIGS. 2 and 3, the cushioning material 7 and the convex portion 2 and the concave portion 3 are covered with a required pitch ( A lateral groove 8 having a width of 75 mm and a width of 1.5 mm is formed by digging a groove 9 which reaches the concave portion 3 from the upper surface of the cushioning material 7 and further reaches the bottom surface of the convex portion 2 on the rear surface side. The cut step portion 6 can also be cut out on the back surface side of the recess 2.
【0007】 このようにして成るコンクリート直貼用床板a(以下、単に床板aとする。) は、床板貼り込み時において、長手方向両側面は図4に示すように、一方の床板 aの凸部2を他方の床板aの凹部3に嵌着し、前後端面では図7に示すように、 一方の床板aの凸部2を他方の床板aの凹部3に嵌着して貼り込むものであるが 、凹部3の溝の深さが凸部2の突出度より深いため、凹部3の溝底と凸部2の先 端間に空間10が形成される。コンクリートの床面に塗布された接着剤は緩衝材 7を接着することはもちろんのこと、両側部と前後端部の切込み段差部6に充填 されて相互の床板aを接着するとともに、横溝8に充填される接着剤は図6に示 すように、凹部3側からは連通口11より空間10に浸入して凹部3と凸部2の 接合部を接合し、凸部2側からは図5、図6に示すように、凸部2の上面にまで 達した溝9より空間10に浸入し、凹部3と凸部2の接合部を接合する。また、 図7に示す前後端部の接合部に形成される空間10も両側部の接合部に形成され る空間10と連通しているから、前後端部の空間10にも接着剤が浸入して接合 強度が増強されるとともに、それだけ上面側合わせ面の変形、狂いを抑制できる 。The floorboard a for concrete direct-adhesion (hereinafter, simply referred to as floorboard a) constructed in this manner has two sides in the longitudinal direction when the floorboard is attached, as shown in FIG. The portion 2 is fitted in the recess 3 of the other floor plate a, and the front and rear end surfaces are fitted and the protrusion 2 of one floor plate a is fitted in the recess 3 of the other floor plate a as shown in FIG. 7. Since the depth of the groove of the concave portion 3 is deeper than the protrusion degree of the convex portion 2, the space 10 is formed between the groove bottom of the concave portion 3 and the front end of the convex portion 2. The adhesive applied to the concrete floor surface not only bonds the cushioning material 7, but also fills the cut step portions 6 on both sides and the front and rear ends to bond the floor boards a to each other and to the lateral groove 8. As shown in FIG. 6, the filled adhesive penetrates into the space 10 through the communication port 11 from the concave portion 3 side to bond the joint portion between the concave portion 3 and the convex portion 2 and from the convex portion 2 side to the joint portion of FIG. As shown in FIG. 6, the groove 9 reaching the upper surface of the convex portion 2 penetrates into the space 10 to join the joint portion between the concave portion 3 and the convex portion 2. In addition, since the space 10 formed at the joints at the front and rear ends shown in FIG. 7 is also in communication with the space 10 formed at the joints at both sides, the adhesive will also penetrate into the spaces 10 at the front and rear ends. As a result, the joint strength is enhanced and deformation and deformation of the upper mating surface can be suppressed.
【0008】 このようにコンクリート下地に塗布される接着剤は多少多くなっても、横溝8 を介して空間10に浸入し、緩衝材7の接着面に適度な接着層を形成し、余分な 接着剤を貼り込み外縁からはみ出すことなく敷設できる。As described above, even if the amount of the adhesive applied to the concrete base is slightly increased, it penetrates into the space 10 through the lateral groove 8 to form an appropriate adhesive layer on the adhesive surface of the cushioning material 7 to prevent excess adhesive. Can be laid without sticking the agent and protruding from the outer edge.
