本考案はマット状の排水材を擁壁、トンネル等の壁面に
取付けるための取付具に関するものである。[Detailed Description of the Invention] The present invention relates to a fixture for attaching a mat-like drainage material to a wall surface such as a retaining wall or a tunnel.
一般に、コンクリート擁壁、もたれ擁壁の排水や、カル
バートボックス、トンネル等の裏面排水には、化学繊維
、天然繊維をランダムに絡合したマット状の排水材や、
繊維状の合成樹脂をランダムに交叉し、マット状に成形
加工した排水材が用いられている。Generally, for drainage from concrete retaining walls, leaning retaining walls, and back drainage from culvert boxes, tunnels, etc., mat-like drainage materials made of randomly intertwined chemical fibers and natural fibers are used.
Drainage material is used that is made by randomly intersecting fibrous synthetic resin and forming it into a mat shape.
上記マット状の排水材は擁壁やカルバートボックス、ト
ンネル等の壁面に、コンクリート釘や接着テープによっ
て取付けられている。The above-mentioned mat-like drainage material is attached to the walls of retaining walls, culvert boxes, tunnels, etc. using concrete nails or adhesive tape.
しかし、コンクリート釘による場合、取付に手数を要す
るばかりか、コンクリート壁面にひび割れを生じたり、
取付壁面が硬い岩や凹凸があって垂直に打撃できない箇
所には、その取付が極めて困難であるという欠点がある
。However, when using concrete nails, not only is it time-consuming to install, but it can also cause cracks in the concrete wall.
The drawback is that it is extremely difficult to install the device where the mounting wall surface is a hard rock or has uneven surfaces that prevent it from being hit vertically.
また、接着テープによる場合、取付は簡単であるが、取
付壁面の状態、排水材の表面状態が悪いため、接着が困
難で、容易に剥離上で排水材が落下するという問題点が
ある。In addition, when using adhesive tape, installation is easy, but due to the poor condition of the mounting wall surface and the surface condition of the drainage material, adhesion is difficult and there is a problem that the drainage material easily falls off when peeled off.
本考案はこれに鑑みてなしたもので、いかなる取付壁面
にも、マット状の排水材を簡単かつ確実に取付は可能に
した取付具を提供するものである。The present invention was developed in view of this, and provides a mounting tool that allows mat-like drainage material to be easily and reliably mounted on any mounting wall surface.
以下本考案の実施例を図面に基づいて説明する。Embodiments of the present invention will be described below based on the drawings.
図に於てAは合成樹脂で以て一体に成形した取付具で、
この取付具Aは取付部1と差込部2とから威る。In the figure, A is a fixture integrally molded from synthetic resin.
This fixture A has a mounting part 1 and an insertion part 2.
上記取付部1は所要の厚みを有する略正方形、円形、多
角形等の任意の外形形状になし、その下面に水平な接着
座面1aを形成すると共に、中央に凹部1bを、周縁適
所に複数の孔(又は凹部)le、lc・・・・・・を設
ける。The mounting portion 1 has an arbitrary outer shape such as a substantially square, circular, polygonal, etc. having a required thickness, and has a horizontal adhesive seating surface 1a on its lower surface, a recess 1b in the center, and a plurality of recesses 1b at appropriate positions on the periphery. holes (or recesses) le, lc... are provided.
ところで、上記孔1cは時に省略したり、取付部周縁よ
り切欠いて形成することもある。By the way, the hole 1c is sometimes omitted or formed by cutting out from the periphery of the mounting portion.
次に、前記差込部2は所要の長さくマット状排水材の厚
みに応じて適宜決定する。Next, the length of the insertion portion 2 is appropriately determined depending on the thickness of the mat-like drainage material.
を有する柱状に威し、その周面適所に複数の抜止片2a
、2a・・・・・・を突設したものである。It has a columnar shape with a plurality of retaining pieces 2a at appropriate places on its circumferential surface.
, 2a... are provided protrudingly.
ところで、上記差込部2の形状は略三角錐状、略円錐状
、砲弾状、多角錐状等差込みやすい柱状に威すものであ
る。By the way, the shape of the insertion part 2 is a columnar shape that is easy to insert, such as a substantially triangular pyramid shape, a substantially conical shape, a cannonball shape, and a polygonal pyramid shape.
また、上記抜止片2aは、実施例では上下に所要間隔を
おいて対称的に設けたが、マット状排水材の厚みに合せ
て、一方を省略したり、散点的に配設することもある。Further, in the embodiment, the retaining pieces 2a are provided symmetrically at the required intervals vertically, but depending on the thickness of the mat-like drainage material, one of the retaining pieces 2a may be omitted or they may be disposed in a scattered manner. be.
よって、本考案に係る取付具を用いる時は、取付具Aの
接着座面1aに速乾性接着剤を塗布して、取付壁面Wに
所要間隔をおいて配設すると、接着剤Cは取付部1の凹
部1b、孔(又は切欠き)lc内にも充填されて取付壁
面に確固に固着される。Therefore, when using the fixture according to the present invention, if a quick-drying adhesive is applied to the adhesive seat surface 1a of the fixture A and the adhesive is placed on the mounting wall surface W at a required interval, the adhesive C will be applied to the mounting part. The concave portion 1b and hole (or notch) lc of No. 1 are also filled and firmly fixed to the mounting wall surface.
その後、マット状排水材Gを差込部2の上方より押込む
と、差込部2が排水材中に差込まれ、抜止片2aによっ
て排水材は簡単かつ確実に取付けることができる。Thereafter, when the mat-like drainage material G is pushed in from above the insertion part 2, the insertion part 2 is inserted into the drainage material, and the drainage material can be easily and reliably attached by the retaining piece 2a.
ところで上記接着剤は、取付壁面が水もれ等で濡れてい
る時には、水中エポキシ等の接着剤を用いるもので、ま
た、接着剤は取付部の接着座面に予め塗布しておき、そ
の上面に剥離自在のシールを貼着しておくことも可能で
ある。By the way, when the mounting wall surface is wet due to water leakage, an adhesive such as underwater epoxy is used for the above adhesive.Also, the adhesive is applied in advance to the adhesive seat surface of the mounting part, and then the upper surface is It is also possible to attach a removable sticker to the holder.
従って、本考案による時は、構造簡単で安価に大量生産
できると共に、マット状排水材を簡単かつ確実に取付け
ることができる。Therefore, according to the present invention, the structure is simple and can be mass-produced at low cost, and the mat-like drainage material can be easily and reliably attached.
また、取付部に孔(又は切欠き)等を設けたときは、軽
量化が図れると共に、より確固に固着することができる
。Furthermore, when a hole (or notch) or the like is provided in the attachment part, weight reduction can be achieved and the attachment can be more firmly fixed.
更に、その取付作業も何らの熟練を要しない等のすぐれ
