【課題】打ち込み式の良い点と、薬液注入式の良い点を併せ持ち、更に接着強度を高めたアンカーボルトを開発することが課題です。【解決手段】現在の打ち込み式と薬液注入式で共通な点は、縦孔を削り、その縦孔の側壁とアンカー本体や薬液本体との接触圧のみで、アンカー強度を出しています。本発明は、アンカーボルト挿入用縦孔を開削後、前記アンカーボルト挿入用縦孔の底部に薬液ガラス管を置き、その上にガイド付きアンカー開補助基台を設置し、振動ドリルで回転させながら、サイドグリップアンカー本体を降ろして行きます。薬液ガラス管は、破損し薬液が、流出します。さらに降ろして行くと、ガイド付きアンカー開補助基台にサイドグリップアンカー本体が、食い込んでいき、サイドグリップアンカー本体の先端が、押し広げられ、縦孔壁面を掘削します。【選択図】 図２PROBLEM TO BE SOLVED: To develop an anchor bolt which has both a good point of a driving type and a good point of a chemical injection type and has further improved adhesive strength. SOLUTION: The common point between the current driving type and the chemical injection type is that the vertical hole is cut and the anchor strength is obtained only by the contact pressure between the side wall of the vertical hole and the anchor body or the chemical solution body. In the present invention, after excavating a vertical hole for inserting an anchor bolt, a chemical glass tube is placed at the bottom of the vertical hole for inserting an anchor bolt, a guided anchor opening auxiliary base is installed on the glass tube, and the anchor bolt is rotated by a vibration drill. , Side grip anchor body will be lowered. The chemical glass tube will be damaged and the chemical will flow out. As it is further lowered, the side grip anchor body bites into the guided anchor opening auxiliary base, the tip of the side grip anchor body is expanded, and the vertical hole wall surface is excavated.

Description
あと施工アンカーの分野は、施工技術の優劣で、アンカーボルトの強度や耐久性に大きく影響が出てきます。 In the field of construction anchors, the superiority and inferiority of construction technology greatly affects the strength and durability of anchor bolts.
平成２４年12月の笹子トンネル天井板落下事故は、記憶に新しいところです。
あの事故で、薬液注入神話が崩れました。
The Sasako tunnel ceiling board fall accident in December 2012 is a new place in my memory.
That accident broke the myth of injecting chemicals.
あと施工アンカーの施工方法は、大きく2種類に分けられます。
打ち込み方式と薬液注入アンカー方式の2種類です。
Post-installed anchor construction methods can be broadly divided into two types.
There are two types: driving method and chemical injection anchor method.
打ち込み方式は、キリで下孔を開け、下孔にアンカーボルトを挿入し、ピン若しくは、玉を打ち込み、アンカー先端部付近を拡張して、下孔の壁にくい込ませて固定します。 The driving method is to make a pilot hole with a drill, insert an anchor bolt into the pilot hole, drive a pin or a ball, expand the area near the tip of the anchor, and insert it into the wall of the pilot hole to fix it.
薬液注入アンカー方式は、キリで下孔を開け、下孔に薬液を注入し、アンカーボルトを挿入し、化学反応で硬化させ、アンカー強度を増します。
笹子トンネルは、この方式のアンカーでした。
In the chemical injection anchor method, a pilot hole is made with a drill, a chemical solution is injected into the pilot hole, an anchor bolt is inserted, and the anchor bolt is hardened by a chemical reaction to increase the anchor strength.
The Sasago Tunnel was an anchor of this type.
特願2003-340526号は、あと施工アンカー工法に付いてのべられています。 Japanese Patent Application No. 2003-340526 is mentioned in the post-installed anchor construction method.
特願2016-216710号は、拡張アンカーについてのべられています。 Japanese Patent Application No. 2016-216710 mentions expansion anchors.
拡張打ち込み式のよいところは、下孔を開け、打ち込んですぐに作業が、済み、器具固定などが出来ることです。欠点は、アンカー先端を広げて、掘削した孔の側面に強く接触させるために、ハンマーなどで強く打ち込むので、周囲を破壊し、強度を弱める可能性があります。 The good thing about the extended driving type is that you can make a pilot hole, work immediately after driving, and fix the equipment. The disadvantage is that the tip of the anchor is widened and hit hard with a hammer to make strong contact with the side of the excavated hole, which may destroy the surroundings and weaken the strength.
薬液注入アンカーは、下孔を開け、薬剤を下孔に注入し、アンカーボルトを挿入し、一定時間待てば、硬化します。薬液注入アンカーのよいところは、ハンマーなどで強く打ち込まないので、周囲を破壊する可能性がありません。欠点は、アンカーボルトが、まっすぐで、孔の側面との接触力が、薬液注入溶剤の硬化力に成り、硬化力が、弱いとアンカーボルトが、引っ張り力に負けて、すっぽ抜けてしまい大事故につながります。更に、施工後に薬液注入溶剤の硬化時間がかかりますので、硬化完了まで、待っておく必要が、有ります。
その間に少しでも動くと、不良施工になり強度の保証ができなくなります。
The chemical injection anchor will cure after making a pilot hole, injecting the drug into the pilot hole, inserting the anchor bolt, and waiting for a certain period of time. The good thing about the chemical injection anchor is that it doesn't hit hard with a hammer, so there is no possibility of damaging the surroundings. The disadvantage is that the anchor bolt is straight and the contact force with the side surface of the hole becomes the curing force of the chemical injection solvent, and if the curing force is weak, the anchor bolt loses the pulling force and slips out completely. It will lead to an accident. In addition, it takes time to cure the chemical injection solvent after construction, so it is necessary to wait until the curing is completed.
If you move even a little during that time, the construction will be defective and the strength cannot be guaranteed.
打ち込み式の良い点と、薬液注入式の良い点を併せ持ち、更に接着強度を高めたアンカーボルトを開発することが課題です。 The challenge is to develop an anchor bolt that has both the good points of the driving type and the good points of the chemical injection type, and further enhances the adhesive strength.
現在の打ち込み式と薬液注入式で共通な点は、縦孔を削り、その縦孔の側壁とアンカー本体や薬液本体との接触圧のみで、アンカー強度を出しています。
本発明は、アンカーボルト挿入用縦孔を開削後、前記アンカーボルト挿入用縦孔の底部に薬液ガラス管を置き、その上にガイド付きアンカー開補助基台を設置し、振動ドリルで回転させながら、サイドグリップアンカー本体を降ろして行きます。
The common point between the current driving type and the chemical injection type is that the vertical hole is cut and the anchor strength is obtained only by the contact pressure between the side wall of the vertical hole and the anchor body or the chemical solution body.
In the present invention, after excavating a vertical hole for inserting an anchor bolt, a chemical glass tube is placed at the bottom of the vertical hole for inserting an anchor bolt, a guided anchor opening auxiliary base is installed on the glass tube, and the anchor bolt is rotated by a vibration drill. , Side grip anchor body will be lowered.
薬液ガラス管は、破損し薬液が、流出します。さらに降ろして行くと、ガイド付きアンカー開補助基台にサイドグリップアンカー本体が、食い込んでいき、サイドグリップアンカー本体の先端が、押し広げられ、縦孔壁面を掘削します。 The chemical glass tube will be damaged and the chemical will flow out. As it is further lowered, the side grip anchor body bites into the guided anchor opening auxiliary base, the tip of the side grip anchor body is expanded, and the vertical hole wall surface is excavated.
従来の打ち込み式アンカーや薬液注入アンカーでは、出来なかった強度が、実現でき、経年変化してもオープンクリップの効果で、強度が落ちない。 Strength that could not be achieved with conventional driving anchors and chemical injection anchors can be achieved, and the strength does not decrease due to the effect of the open clip even if it changes over time.
あと施工アンカーの安全性が格段に良くなる。 The safety of post-installed anchors will be significantly improved.
薬液注入アンカーのように硬化時間を待たずに、打込ピンを打ち込み、前記拡張式アンカーを拡張させたらすぐに使用できます。 It can be used as soon as the expansion anchor is expanded by driving the driving pin without waiting for the curing time like the chemical injection anchor.
