Description

本発明は、例えば石膏ボード等のクロス下地同士がほぼ直角に結合された出隅または入隅に使用される下地コーナー材に関するものである。 TECHNICAL FIELD The present invention relates to a base corner material used in a projecting corner or a entering corner where, for example, gypsum boards or the like are bonded to each other at substantially right angles.

建物の内装工事では、壁紙、布地、合成樹脂クロス等の壁装材(クロス)で施工することが主流となっている。この種の壁装材(クロス)を貼り付けする際、美麗な仕上げを得るためには、下地面を凹凸のない平滑な面に仕上げておく必要がある。通常用いられる石膏ボードや合板の表面は平坦であるが、その接合部には継ぎ目が表出する。 In the interior work of buildings, wall coverings (cloths) such as wallpaper, cloth, and synthetic resin cloth are the mainstream. When applying this kind of wall covering (cloth), in order to obtain a beautiful finish, it is necessary to finish the base surface to a smooth surface without unevenness. The surface of gypsum board or plywood that is commonly used is flat, but a seam appears at the joint.

そのため、石膏ボードや合板の継ぎ目をパテ処理して平滑にする。特に出っ張った側の角である出隅部や、凹んだ側の角である入隅部では、多くの場合に石膏ボードや合板の継ぎ目となり、その下地仕上げは面倒の多いものであった。例えば、建物の壁面の出隅部や入隅部を平坦に仕上げるために、薄い合成樹脂製のL型コーナー材を出隅部や入隅部にあてがって角を出し、パテ剤等で各壁面を平滑化する施工が行われている。 Therefore, the seams of gypsum board and plywood are putty-treated to be smooth. In particular, at the corners on the protruding side and the corners on the concave side, in many cases, the seams of gypsum board or plywood were used, and the ground finish was troublesome. For example, in order to finish the projecting and entering corners of the wall surface of the building flat, apply a thin synthetic resin L-shaped corner material to the projecting and entering corners to make corners, and put each wall surface with a putty agent etc. Is being carried out.

このL型コーナー材の材質としては、従来から紙製、金属製、合成樹脂製あるいはこれらの材質を組み合わせて複合体としたものが商品化されてきた。 As the material of the L-shaped corner material, conventionally, a material made of paper, metal, synthetic resin, or a combination of these materials has been commercialized.

例えば、突出部を有するコーナー材によって、建物の構造材の2つの壁面が交差して角部を形成する隅部分の角部を明確に現出させるために、一対の剛性を有する平板部と、これら一対の平板部が前記2つの壁面のなす角度になるように一対の平板部間を屈曲可能に連絡する蝶番部と、この蝶番部に平板部の厚さ方向に対して少なくとも一側に突出する突出部とを一体的に設けたコーナー材が提案されている(例えば、特許文献1参照)。 For example, by a corner material having a protruding portion, a pair of flat plate portions having rigidity to clearly reveal a corner portion of a corner portion where two wall surfaces of a structural material of a building intersect to form a corner portion, A hinge portion that flexibly connects between the pair of flat plate portions such that the pair of flat plate portions forms an angle formed by the two wall surfaces, and a hinge portion that projects toward at least one side in the thickness direction of the flat plate portion. There has been proposed a corner member integrally provided with a protruding portion (see, for example, Patent Document 1).

このようなコーナー材としては、コーナー部分を覆うように下地に貼り付け、コーナー材の上からパテ剤を展延塗布し、平滑化した後に展延塗布されたパテ剤を充分に乾燥させて、クロスを貼着する。パテ剤をパテベラ等で展延塗布する際に、パテ剤と下地とコーナー材との馴染みをよくするため、コーナー材の殆どには平板部に多数の貫通孔が穿設されている。 As such a corner material, the corner material is attached to a base so as to cover the corner portion, the putty agent is spread and applied on the corner material, and after smoothing, the spread and applied putty agent is sufficiently dried, Stick the cloth. When the putty agent is spread and applied by a putty vera or the like, a large number of through holes are formed in the flat plate portion of most of the corner material in order to improve the familiarity between the putty agent, the base and the corner material.

貫通孔の種類については、丸形、長丸形、四角形、楕円形等々のものがあり、穿設位置についても、一つの平板部に2列以上、千鳥状に穿設されるのが殆どである。また、同一の貫通孔を平板部に備えるものはまれであり、平板部の列ごとに相違する貫通孔を備えるものや、丸形のみの貫通孔を備えるものが主流となっている。 There are various types of through-holes such as round, oval, quadrangular, and elliptical, and most of the holes are staggered in two or more rows on one flat plate. is there. Further, it is rare that the flat plate portion has the same through hole, and the one having a different through hole for each row of the flat plate portion and the one having only a round through hole are predominant.

本発明においては、クロス張りされる2つの壁面が交わる入隅部又は出隅部の交線に沿って配される長尺体である下地コーナー材であって、長尺体の長手方向に沿った中央部に沿った曲折部と、中央部の両側に形成された一対の平板部と、一対の平板部に表裏面を貫通する多数の貫通孔とを備え、多数の貫通孔の全てが、長手方向に直交する方向の最大横幅長に対して、長尺体の長手方向に沿った方向の最大縦幅長が長い長孔であるため、下地に貼り付けてパテ塗りして平滑化した後にパテ剤が乾燥してもヤセが少ない利点が得られる。 In the present invention, a base corner material that is a long body arranged along a line of intersection of an entrance corner or an exit corner where two wall surfaces crossed with each other intersect, and is a long corner of the long body. A bent portion along the central portion, a pair of flat plate portions formed on both sides of the central portion, and a large number of through holes penetrating the front and back surfaces in the pair of flat plate portions, all of the large number of through holes, Since the maximum vertical width in the direction along the longitudinal direction of the elongated body is longer than the maximum horizontal width in the direction orthogonal to the longitudinal direction, after pasting it on the base and applying putty to smooth it Even if the putty agent is dried, the advantage of having a small amount of dryness can be obtained.

具体的に説明すると、下地コーナー材を設置する際には、設置するコーナー部にパテ剤を薄く塗るか、コーナー材をコーナー部に両面テープで貼着した上で、更に、パテ剤を下地コーナー材の上から塗って、下地コーナー材とコーナー部との段差を無くすように両者をパテベラ等で平滑化する。この際、下地コーナー材とコーナー部との段差はコーナー材の長手方向に伸びているため、作業者は下地コーナー材の長手方向に沿ってパテベラ等でパテ剤を塗り広げることとなる。 Specifically, when installing the base corner material, apply a thin putty agent to the corner part to be installed, or stick the corner material to the corner part with double-sided tape, and then add the putty agent to the base corner. Apply from above the material, and smooth both with a putter, etc. so as to eliminate the step between the base corner material and the corner portion. At this time, since the level difference between the base corner material and the corner portion extends in the longitudinal direction of the corner material, the worker spreads the putty agent with a putter or the like along the longitudinal direction of the base corner material.

この際に、パテベラ等によって同じように平滑化させた下地について、下地コーナー材の貫通孔の種類に応じて明確な差が生じ、長手方向に直交する方向の最大横幅長に対して、長尺体の長手方向に沿った方向の最大縦幅長が長い長孔である貫通孔においては、パテ剤のヤセが少ないことが検証され、本発明に至ったものである。 At this time, there is a clear difference depending on the type of the through-holes of the base corner material for the base smoothed in the same manner with a putty vera, etc. The present invention has been completed by verifying that the putty agent is less likely to be lost in the through hole, which is a long hole having a long maximum vertical width along the longitudinal direction of the body.

本発明の下地コーナー材の一対の平板部形成される長孔の貫通孔については、好ましくは、長孔の最大横幅長に対する最大縦幅長の比率が、1.5倍以上であるものがヤセが少なく良好である。具体的な長孔としては、例えば、長孔が、長丸孔、楕円孔、ひし形孔等が挙げられる。 Regarding the through holes of the long holes formed in the pair of flat plate portions of the base corner material of the present invention, it is preferable that the ratio of the maximum vertical width to the maximum horizontal width of the long holes is 1.5 times or more. Is less and is good. Specific examples of the long holes include long holes, oval holes, elliptical holes, and diamond-shaped holes.

この現象の作用機構については、種々の仮説が考慮されるが、次の仮説が最も有力であると思われる。即ち、塗り広げられるパテ剤は微細な骨材と、水や接着剤等の液体とが混合されたものであり、所謂「スラリー流体」の一種であり、このスラリー流体の挙動による作用機構が良好な説明を与える。即ち、長手方向に沿ってパテベラを往復してパテ剤を展延塗布しながら平滑化する場合、パテベラの素早い動きによって、スラリー流体のパテ剤がずり応力に対向するために固化したり、その後パテベラが通り過ぎた後に流動化したりする。 Regarding the mechanism of action of this phenomenon, various hypotheses are considered, but the following hypothesis seems to be most effective. That is, the putty agent to be spread is a mixture of fine aggregate and a liquid such as water or an adhesive and is a kind of so-called "slurry fluid", and the action mechanism by the behavior of this slurry fluid is good. Give a detailed explanation. That is, when smoothing while putting and applying the putty agent by reciprocating the putty agent along the longitudinal direction, the putty agent of the slurry fluid is solidified because the putty agent faces the shear stress by the quick movement of the putty agent, and then the putty agent is solidified. It fluidizes after passing by.

詳しくは、スラリー流体とは液体と固体粒子との懸濁液であり、泥漿(でいしよう)とも呼ばれ、状況によって固体のような挙動と、液体のような挙動とをとる。更に詳しくは、スラリー流体の一種とされるチキソトロピーは、非ニュートン流体の一種で、ゲルのような塑性固体とゾルのような中間的な物質を示す。下地調整に用いられるパテ剤についても、似たような挙動を示すと考えられる。 Specifically, the slurry fluid is a suspension of liquid and solid particles, and is also called sludge, and behaves like a solid and behaves like a liquid depending on the situation. More specifically, thixotropy, which is a kind of slurry fluid, is a kind of non-Newtonian fluid and shows an intermediate substance such as a plastic solid and a sol such as a gel. It is considered that the putty agent used for the undercoat adjustment also exhibits similar behavior.

図1は下地コーナー材の貫通孔へのパテ展延工程を説明する説明図である。図1のa図に示す通り、下地コーナー材11の平板部12上にパテベラ14がパテ剤15を展延しながら貫通孔13へ移動させる。b図に示す通り、平板部12の貫通孔13上にパテベラ14に押されてパテ剤が移動されてくるとパテベラ14で押されたパテ剤15は貫通孔13内に逃げる。この際には、貫通孔13の全ての方向に押されるため、貫通孔13の幅が広い場合には、広い幅全体に行き渡り、パテベラ14の先端を超えて展延方向と反対する方向へのパテ剤の逃げは殆ど無いと考えられる。 FIG. 1 is an explanatory diagram illustrating a step of spreading putty into a through hole of a base corner material. As shown in FIG. 1A, the putty vera 14 moves the putty agent 15 to the through hole 13 while spreading the putty agent 15 on the flat plate portion 12 of the base corner material 11. As shown in FIG. b, when the putty agent 14 is pushed by the putty vera 14 onto the through hole 13 of the flat plate portion 12, the putty agent 15 pushed by the putty vera 14 escapes into the through hole 13. At this time, since it is pushed in all directions of the through hole 13, when the width of the through hole 13 is wide, it extends over the entire wide width and goes beyond the tip of the putty vera 14 in a direction opposite to the spreading direction. It is considered that there is almost no escape of the putty agent.

c図に示す通り、貫通孔13の幅が狭く、パテベラ14の展延方向に長い場合には、パテベラ14の先端を超えて展延方向と反対する方向へのパテ剤の逃げが発生し、その流れが一旦平滑化した貫通孔部分の表面を持ち上げ、結果的に膨れる現象が生じたものと考えられる。 As shown in FIG. c, when the width of the through hole 13 is narrow and is long in the spreading direction of the putty vera 14, escape of the putty agent occurs in a direction opposite to the spreading direction beyond the tip of the putty vera 14, It is considered that the flow lifted the surface of the through-hole portion, which had been once smoothed, resulting in the phenomenon of swelling.

d図に示す通り、貫通孔13からパテベラ14が外れる寸前には、貫通孔13の底面方向へのパテ剤15の逃げがなくなるため、一旦膨れた表面はそのままの状態となり、パテ剤の乾燥に伴って、水分が蒸発しても、結果的にヤセが発生し難く、更には膨れの状態となることもあるとと考えられる。 As shown in FIG. 3D, just before the putty vera 14 comes off from the through hole 13, the putty agent 15 does not escape toward the bottom surface of the through hole 13, so that the swollen surface remains as it is and the putty agent is dried. As a result, even if the water evaporates, it is considered that as a result, the fray is unlikely to occur and the swelling may occur.

本発明では、一対の平板部に表裏面を貫通する多数の貫通孔の全てが、長手方向に直交する最大横幅長に対して、長尺体の長手方向に沿った最大縦幅長が長い長孔であるため、下地に貼り付けてパテ塗りして平滑化した後にパテ剤が乾燥してもヤセが少ない利点が得られるものである。 In the present invention, all of the large number of through-holes penetrating the front and back surfaces of the pair of flat plate portions are such that the maximum vertical width along the longitudinal direction of the elongated body is long with respect to the maximum lateral width orthogonal to the longitudinal direction. Since it is a hole, even if the putty agent is dried after being pasted on the base, putty-coated and smoothed, the advantage of having less fuzz is obtained.

本発明の下地コーナー材は、クロス張りされる2つの壁面が交わる入隅部又は出隅部の交線に沿って配される長尺体であればよく、紙製、金属製、合成樹脂製あるいはこれらの材質を組み合わせて複合体とした素材で構成されればよい。例えば、金属製又はプラスチック製で可撓性のないL字状のコーナー材や、合成樹脂製の可撓性のあるテープ材で長手方向中央に曲折部を備え、使用時に曲折部で追ってL字状にするコーナーテープ材とも呼ばれるものであればよい。特に、可撓性を有する素材であれば、曲折部と一対の平板部とを同一の可撓性を有する素材で構成か、一対の平板部が平板状を保持可能である程度に腰がある素材とし尚且つ曲折部及びその近傍を可撓性を有する素材で構成するコーナーテープ材が汎用性が高い。 The base corner material of the present invention may be a long body arranged along the line of intersection of the entrance corner or the exit corner where two wall surfaces to be crossed intersect, and may be made of paper, metal, or synthetic resin. Alternatively, the material may be a composite material formed by combining these materials. For example, an inflexible L-shaped corner material made of metal or plastic, or a flexible tape material made of synthetic resin and provided with a bent portion at the center in the longitudinal direction, and the L-shaped portion is followed by the bent portion when used. What is also called a corner tape material to be shaped may be used. In particular, as long as it is a flexible material, the bent portion and the pair of flat plate portions are made of the same flexible material, or the pair of flat plate portions can hold a flat plate shape and have a certain degree of flexibility. Moreover, the corner tape material in which the bent portion and its vicinity are made of a flexible material has high versatility.

これら曲折部と一対の平板部とを構成する合成樹脂素材としては、ポリ塩化ビニル、PET樹脂、HIPS樹脂、ABS樹脂、エラストマ樹脂ゴム、或いはこれらの複合体等の合成樹脂が挙げられる。また、可撓性については、一対の平板部が曲折部に対して平たい状態でロール状に捲回可能であり、尚且つ、長尺体に力を加えない状態時に一対の平板部が曲折部を間にして互いに略直交する断面形状を保つ復元性を有する程度の可撓性があればよい。このためには、ある程度の薄さが必要となり、具体的には、平板部0.3〜1.0mm、好ましくは0.4〜0.6mmの厚さとし、曲折部は平板部よりも薄く、具体的には、0.2〜0.7mm、好ましくは0.25〜0.5mmの厚さとする。 Examples of the synthetic resin material forming the bent portions and the pair of flat plate portions include synthetic resins such as polyvinyl chloride, PET resin, HIPS resin, ABS resin, elastomer resin rubber, and composites thereof. Regarding flexibility, the pair of flat plate portions can be wound into a roll in a flat state with respect to the bent portion, and the pair of flat plate portions are bent when the force is not applied to the elongated body. It suffices that it is flexible enough to have a restoring property such that the cross-sectional shapes that are substantially orthogonal to each other are maintained with the space therebetween. For this purpose, a certain degree of thinness is required. Specifically, the flat plate portion has a thickness of 0.3 to 1.0 mm, preferably 0.4 to 0.6 mm, and the bent portion is thinner than the flat plate portion. Specifically, the thickness is 0.2 to 0.7 mm, preferably 0.25 to 0.5 mm.

例えば、合成樹脂素材を押し出し機で押し出しつつ、中央部の曲折部に対して一対の平板部をL字状に成形して長尺体を得ればよい。この場合、得られた長尺体は、一対の平板部が曲折部に対して平たい状態でロール状に捲回可能であり、尚且つ、長尺体に力を加えない状態時に一対の平板部が曲折部を間にして互いに略直交する断面形状を保つ復元性を有するように構成されればよい。 For example, while extruding a synthetic resin material with an extruder, a pair of flat plate portions may be molded into an L shape with respect to the bent portion in the central portion to obtain a long body. In this case, the obtained long body can be wound in a roll shape with the pair of flat plate portions being flat with respect to the bent portion, and the pair of flat plate portions can be wound when no force is applied to the long body. May be configured to have a restoring property that maintains cross-sectional shapes that are substantially orthogonal to each other with the bent portion in between.

本発明の下地コーナー材の一対の平板部同士のなす角度は、略直交、より具体的には、84°以上90°以下、より好ましくは86°以上90°以下である。90°を越えると出隅のコーナーに配する際に平板部をコーナーの一面に貼着する際に湾曲又は浮き上がりしやすくなり、同様に、84°を下回ると入隅のコーナーに配する際に平板部をコーナーの一面に貼着する際に湾曲しやすくなるためである。 The angle formed by the pair of flat plate portions of the base corner material of the present invention is substantially orthogonal, more specifically, 84° or more and 90° or less, and more preferably 86° or more and 90° or less. If it exceeds 90°, it tends to bend or rise when the flat plate part is attached to one surface of the corner when arranging it in the corner of the outside corner. Similarly, if it is less than 84°, it will be arranged in the corner of the inside corner. This is because when the flat plate portion is attached to one surface of the corner, it tends to bend.

The flat plate portion 23 and a large number of through holes 24 formed in the pair of flat plate portions 23 in three rows penetrating the front and back surfaces are provided.

これら図2〜図6に示した下地コーナー材を用いて、下地調整を行って貫通孔部分のヤセを検証した。具体的には、個々の下地コーナー材を出隅部を模した角柱材上の試験片に両面テープで貼着した後、同一のパテ剤を用いて、同一の操作手順及び操作速度でパテベラでパテ剤の展延塗布操作を行った。個々の下地コーナー材について、各々3つの試験片で同じ操作を行った。 By using the base corner material shown in FIGS. 2 to 6, the base was adjusted to verify the texture of the through hole. Specifically, after attaching each base corner material to the test piece on the prismatic material simulating the projected corner part with double-sided tape, using the same putty agent, with a puttera with the same operating procedure and operating speed. A spreading application operation of the putty agent was performed. The same operation was performed on each of the three test pieces for each base corner material.

展延塗布操作を行った翌日に、下地調整の貫通孔部分のヤセを検証した。検証は下地調整を行ったものと相違する者が行い、具体的にどの下地コーナー材を用いたのかを伏せて行った。結果を表1に示す。尚、表中のヤセの量は、個々の平均値を示しており、パテ塗布面よりヤセている場合はマイナス、逆に膨らんでいる場合はプラスとし、数値が大きいほど良好な値である。 The day after the spread coating operation was performed, the texture of the through-hole portion for the base adjustment was verified. The verification was carried out by a person different from the one who prepared the groundwork, and the groundwork corner material used was turned down. The results are shown in Table 1. In addition, the amount of fray in the table shows each average value. When the fray is more than the putty-coated surface, it is negative, and when it is swollen, it is positive. The larger the number, the better the value.

表1に示した通り、下地コーナー材の長手方向に長い孔形状ほど、ヤセが少なく良好な結果が得られた。逆に横巾方向に長い孔形状にすると、縦横寸法が同じである丸孔やひし形に比べてむしろ悪い結果となることが示された。尚、ヤセの量がプラスになっている場合は、表面から出ているパテ剤を削れば良いため、パテ剤を塗布する手間に比べれば短時間に処理できる。 As shown in Table 1, the longer the shape of the hole in the longitudinal direction of the base corner material, the less the texture was, and the better results were obtained. On the contrary, it was shown that when the hole shape is long in the width direction, the result is rather worse than that of the round hole or the rhombus having the same vertical and horizontal dimensions. In addition, when the amount of waste is positive, the putty agent protruding from the surface may be scraped off, so that it is possible to process the putty agent in a shorter time than the time and effort required to apply the putty agent.

また、アンカー効果については、孔の形状では明確な差はなく、孔の面積とピッチに依存している(孔の面積が大きく、ピッチが細かい程強くなる)ため、従来の製品の孔を本発明の孔形状に面積を同じにして置き換えれば、アンカー効果を維持したままヤセを少なく改善できる。 Also, regarding the anchor effect, there is no clear difference in the shape of the holes, but it depends on the area and pitch of the holes (the larger the area of the holes and the smaller the pitch, the stronger). If the hole shape of the present invention is replaced with the same area, it is possible to improve the texture while maintaining the anchor effect.
