Abstract
Description
この発明は、法面補強部材を取り付けるためのアンカーボルトを所望の高さに設置するための法面補強部材取付ボルトの取付高さ設定部材に関する。 The present invention relates to a mounting height setting member for a slope reinforcing member mounting bolt for installing an anchor bolt for mounting a slope reinforcing member at a desired height.
法面を補強するために各種の受圧パネルが取り付けられている。例えば特許文献1や特許文献2などには、さまざまな受圧パネルが提案されている。いずれの受圧パネルも予め法面に設置されたアンカーボルトの先端部に取り付けられる。受圧パネルの中心部の穴にアンカーボルトを通し、その上からナットを取り付けて受圧パネルが設置される。
Various pressure receiving panels are attached to reinforce the slope. For example,
そのためには、アンカーボルトの先端部はそれぞれの受圧パネルに合った適切な高さで地上に突出していなければならない。それよりも低ければナットを取り付けることができず、高ければナット先端が法面から過剰に突出す。しかし、特許文献1や特許文献2にはアンカーボルトの設置方法については特に説明はない。
For this purpose, the tip of the anchor bolt must protrude to the ground at an appropriate height that matches the pressure receiving panel. If it is lower than that, the nut cannot be attached, and if it is higher, the nut tip protrudes excessively from the slope. However,
これまでアンカーボルトの設置においては、物差しなどを当てて突出高さを決め、固定のためのセメントが硬化するまでの間は木の棒などを組んでアンカーボルトを仮に固定し、セメントの硬化後にその木の棒などを撤去していた。 Until now, when installing anchor bolts, determine the protruding height using a ruler, etc., and fix the anchor bolts temporarily with a wooden stick etc. until the cement for fixing is hardened. The wooden stick was removed.
従来のアンカーボルトの設置では、その都度、木材などを組み合わせてアンカーボルトの仮支持を行っていたが、このような支持部材の取付・撤去は煩雑な作業である。また、作業が正確になされなければ、アンカーボルトの上端部の高さが不揃いになるおそれがある。 In the conventional installation of anchor bolts, temporary support of the anchor bolts is performed by combining wood or the like each time. However, mounting and removing of such support members is a complicated operation. Further, if the work is not performed accurately, the heights of the upper ends of the anchor bolts may be uneven.
この発明は、法面補強部材取付ボルトに対して簡単に着脱でき、しかも、法面補強部材取付ボルトの上端部の高さを適切に設定できる法面補強部材取付ボルトの取付高さ設定部材を提供することを目的とする。 The present invention provides a mounting height setting member for a slope reinforcing member mounting bolt that can be easily attached to and detached from the slope reinforcing member mounting bolt and that can appropriately set the height of the upper end of the slope reinforcing member mounting bolt. The purpose is to provide.
上記の課題を解決するために、この発明の法面補強部材取付ボルトの取付高さ設定部材は、法面に接する法面当接部材と、法面補強部材取付ボルトに着脱自在に接続される法面補強部材取付ボルト接続部材と、法面当接部材から所定の距離に設けられた法面補強部材取付ボルト上端部当接部材を有する。さらに、法面補強部材取付ボルト接続部材を法面補強部材取付ボルトに係合するメネジを有する部材とすることができる。 In order to solve the above problems, the mounting height setting member of the slope reinforcing member mounting bolt according to the present invention is detachably connected to the slope contact member that contacts the slope and the slope reinforcing member mounting bolt. A slope reinforcing member attachment bolt connecting member and a slope reinforcement member attachment bolt upper end contact member provided at a predetermined distance from the slope contact member. Further, the slope reinforcing member mounting bolt connecting member can be a member having a female screw that engages the slope reinforcing member mounting bolt.
この発明の法面補強部材取付ボルトの取付高さ設定部材は、法面補強部材取付ボルト接続部材により法面補強部材取付ボルトの上部に取り付けることができ、法面補強部材取付ボルトの上端部を所望の高さに設定して法面に設置することができる。 The mounting height setting member of the slope reinforcing member mounting bolt of this invention can be attached to the upper part of the slope reinforcing member mounting bolt by the slope reinforcing member mounting bolt connecting member, and the upper end portion of the slope reinforcing member mounting bolt is It can be set to a desired height and set on a slope.
本発明を実施するための形態について、図面に基づいて詳細に説明する。図1は法面補強部材取付ボルトの取付高さ設定部材を示す正面図、図2は同側面図である。 EMBODIMENT OF THE INVENTION The form for implementing this invention is demonstrated in detail based on drawing. FIG. 1 is a front view showing a mounting height setting member of a slope reinforcing member mounting bolt, and FIG. 2 is a side view thereof.
法面補強部材取付ボルトの取付高さ設定部材1は、法面GLに接する法面当接部材2と、法面補強部材取付ボルトxに着脱自在に接続される法面補強部材取付ボルト接続部材3と、法面当接部材2から所定の距離に設けられた法面補強部材取付ボルト上端部当接部材4を有する。
The mounting
法面当接部材2は、少なくともアンカー設置用穴をまたいで法面GLに接するだけの広がりがあればよく、ここでは金属棒を使用しているが、面状の部材などであってもよい。
The
法面補強部材取付ボルト接続部材3はアンカーとなる法面補強部材取付ボルトxの上部に着脱自在に接続できる部材である。法面補強部材取付ボルトxは、通常はアンカーボルトと呼ばれる上部にオネジが設けられた金属棒であるので、このオネジに係合するメネジを有する部材が適している。この例では、ナットを使用しており、法面当接部材2に溶接して固定している。これ以外にも、はさみつけによって着脱するクランプ状の部材などを適用してもよい。
The slope reinforcing member mounting
法面補強部材取付ボルト接続部材3であるナットの外周には、先端部がほぼ直角に曲げられたL字状の金属棒4が溶接により取り付けられている。この金属棒4の先端部は、ナットの内側に向けて折り曲げられている。この折り曲げ部4aの下端から法面当接部材2の下端(法面当接箇所)までの距離Lは、後述するように法面補強部材取付ボルトが法面から突き出す長さを規定するものであり、距離Lは所望の突き出す長さに合わせて設定される。

次に、取付高さ設定部材を使用した法面補強部材取付ボルトの設置方法および法面補強部材の設置方法について説明する。図3は、法面補強部材取付ボルトの設置方法を示す断面図である。 Next, a method for installing a slope reinforcing member mounting bolt using a mounting height setting member and a method for installing a slope reinforcing member will be described. FIG. 3 is a cross-sectional view showing a method for installing a slope reinforcing member mounting bolt.
まず、法面において所定の位置に法面補強部材取付ボルトxを設置するための孔yを掘る。通常は、法面補強部材の中心に相当する位置であり、本例では法面GLに対して垂直な方向に掘孔する。しかし、工法に応じてこれ以外の穿孔角度が選択される場合もある。 First, a hole y for installing the slope reinforcing member mounting bolt x is dug in a predetermined position on the slope. Usually, it is a position corresponding to the center of the slope reinforcing member, and in this example, a hole is formed in a direction perpendicular to the slope GL. However, other drilling angles may be selected depending on the construction method.
一方、法面補強部材取付ボルトxの上部に取付高さ設定部材1を取り付ける。取付高さ設定部材1は先に取り付けてもよく、法面補強部材取付ボルトxを孔yに導入した後で取り付けてもよい。本例では、法面補強部材取付ボルト接続部材3は法面補強部材取付ボルトxの上端部に係合するメネジを有するナットであるので、ナット3を法面補強部材取付ボルトxの上端部のオネジに合わせ、法面補強部材取付ボルト上端部当接部材4の折り曲げ部4bに法面補強部材取付ボルトxの上端が当たるように取り付ける。
On the other hand, the attachment
法面補強部材取付ボルトxを孔yに導入し、さらに法面補強部材取付ボルトxを固定するためのセメントを入れる。セメントが固化するまでにある程度時間がかかるが、その間、本発明の取付高さ設定部材1によって法面補強部材取付ボルトxは所定の突出し長さLが維持された状態で支持される。セメントが固化するまでの間、次の法面補強部材取付ボルトの設置作業を開始してもよい。
The slope reinforcing member mounting bolt x is introduced into the hole y, and cement for fixing the slope reinforcing member mounting bolt x is added. While it takes some time for the cement to solidify, the slope reinforcing member mounting bolt x is supported by the mounting
セメントが固化したら、取付高さ設定部材1を法面補強部材取付ボルトxから取り外す。本例では、取付高さ設定部材1が法面補強部材取付ボルトxから離れる方向に回転させることにより、取付高さ設定部材1を切り離すことができる。回収された取付高さ設定部材1は再利用することができる。こうして、法面補強部材取付ボルトxは適切な突出し長さを実現した状態で法面GLに設置される。
When the cement is solidified, the mounting
それから後の法面補強部材の取り付け作業については、特に制限はなく、従来の方法がそのまま適用できる。たとえば、コンクリート板や金属板、あるいは格子状の部材で構成される法面補強部材zの中心部の穴を法面補強部材取付ボルトxに当てはめ、ナットなどの取付部材で法面補強部材zを固定する。法面補強部材取付ボルトxは適切な突出し長さで設置されているので、これらの作業は確実かつ正確に実施できる。施工後においても、過剰に突出した法面補強部材取付ボルトxはなく、その先端部は均一な高さに揃っている。 Then, there is no particular limitation on the subsequent work of attaching the slope reinforcing member, and a conventional method can be applied as it is. For example, a hole at the center of a slope reinforcing member z composed of a concrete plate, a metal plate, or a lattice-like member is applied to the slope reinforcing member mounting bolt x, and the slope reinforcing member z is attached with a mounting member such as a nut. Fix it. Since the slope reinforcing member mounting bolt x is installed with an appropriate protruding length, these operations can be performed reliably and accurately. Even after the construction, the slope reinforcing member mounting bolt x protruding excessively is not present, and the tip portion thereof is aligned at a uniform height.
さらに、法面補強部材取付ボルトの取付高さ設定部材の別の例について説明する。図4は法面補強部材取付ボルトの取付高さ設定部材の別の例を示す正面図である。 Furthermore, another example of the mounting height setting member of the slope reinforcing member mounting bolt will be described. FIG. 4 is a front view showing another example of the mounting height setting member of the slope reinforcing member mounting bolt.
この例では、1本の金属棒の中央部にナットが溶接された構造になっている。ここで、金属棒はナットの上面をまたぐように接続されており、この部分が法面補強部材取付ボルト上端部当接部材となる。一方、ナットの両側に伸びる金属棒の部分は法面当接部材として機能する。 In this example, a nut is welded to the central portion of one metal bar. Here, the metal rod is connected so as to straddle the upper surface of the nut, and this portion becomes a slope reinforcing member mounting bolt upper end contact member. On the other hand, the portion of the metal rod extending on both sides of the nut functions as a slope contact member.
本例の取付高さ設定部材を使用した法面補強部材取付ボルトの設置方法および法面補強部材の設置方法は、図1に示す例と同様である。本例の取付高さ設定部材を使用すると、法面補強部材取付ボルトxの上端の高さは法面GLの高さと同じになる。法面補強部材には中心部が窪んでいるものもあり、そのよう法面補強部材の設置に際して使用できる。したがって、この発明においては、法面当接部材から所定の距離とは、その距離が0である場合や、負の値である場合も含む。 The method of installing the slope reinforcing member mounting bolt and the method of installing the slope reinforcing member using the mounting height setting member of this example are the same as the example shown in FIG. When the mounting height setting member of this example is used, the height of the upper end of the slope reinforcing member mounting bolt x is the same as the height of the slope GL. Some slope reinforcing members have a depressed central portion, and can be used when installing such a slope reinforcing member. Therefore, in the present invention, the predetermined distance from the slope contact member includes a case where the distance is 0 or a negative value.
