Description

考案の詳細な説明Detailed description of the invention

本考案は、アンカーピンの取り付け金具を打設装置の打設ロッド先端に弾性的に固定させて、ボルト等により固定するものと異なり固定部分が緩むことなく長期に亘り固定状態を安定に維持することのできるアンカーピン打設装置のアンカーピン固定金具に関するものである。  In the present invention, the anchor pin mounting bracket is elastically fixed to the tip of the driving rod of the driving device, and unlike the case where it is fixed by a bolt or the like, the fixing portion is stably maintained for a long time without loosening. The present invention relates to an anchor pin fixing bracket of an anchor pin placing device that can be used.

法面保護工事の吹付層下地工程であるラス張り作業は、法面になじみよく張った菱形金網を地山に固定するためにアンカーピンを打設する作業がある。従来の方法としては、2種類のアンカーピン(φ16−400mm・φ9−200mm)をハンマーを使用して人力で打設を行うが、ハンマーを打ち損じて打設始めに支えている手に当たることや、不安定な斜面上で打設作業を行うことから、打ち損じたハンマーが足(位置的に脛等)に当たる危険性があった。  The lath stretching work, which is the spray layer foundation process of slope protection work, includes the work of placing anchor pins in order to fix the rhombus wire mesh stretched well to the slope to the ground. As a conventional method, two types of anchor pins (φ16-400mm / φ9-200mm) are manually driven using a hammer, but the hammer is damaged and hits the hand that supports the beginning of the placement. Since the driving work is performed on an unstable slope, there is a risk that a hammer that has been hit will hit a foot (such as a shin).

従来技術Conventional technology

例えば、文献1(特開2003−41531号公報)には、「主に法面、土壌、コンクリート、岩盤等に打設して用いられる止釘の上部に装着される視認を易化する中空体としてその内面に蛍光顔料或いは蓄光性顔料を塗布されたものを用い、且つその一部にスクリュー構造を有してこれにより加工された止釘に着脱するものを用いるようにした。また、止釘の打設装置においてアタッチメントは止釘の上部に視認を易化する中空体を装着するためのスクリュー構造を保護する空隙を有するようにした」ものであって、「特に大規模な設備の更新等を必要としない簡便な製造方法で製造可能であり、主に法面、土壌、コンクリート、岩盤等に打設して、視認性の向上、範囲の指定、注意の喚起、或いは芸術的表現による法面、土壌、コンクリート、岩盤等の美化等を可能とする方法を実現する」旨説明されている。  For example, Document 1 (Japanese Patent Application Laid-Open No. 2003-41531) states that “a hollow body that facilitates visual recognition mounted on the top of a peg that is mainly used by placing it on a slope, soil, concrete, bedrock or the like. The inner surface is coated with a fluorescent pigment or phosphorescent pigment, and a part thereof has a screw structure and can be attached to and detached from the processed nail. In the installation device, the attachment has an air gap that protects the screw structure for mounting a hollow body that facilitates visual recognition at the top of the peg. Can be manufactured by a simple manufacturing method that does not need to be used, and is mainly placed on slopes, soil, concrete, bedrock, etc. to improve visibility, specify the range, call attention, or artistic expression Surface, soil, concrete DOO, implementing the method to allow beautification like bedrock, etc. "are effect described.

しかしながら、上記文献1には本考案の如き、アンカーピンの取り付け金具が打設装置の打設ロッド先端に弾性的に固定して、ボルト等により固定するのと異なり固定部分が緩むことなく長期に亘り固定状態を安定的に保持することができず、また複数の種類のアンカーピンを保持できて打設位置の状況に応じて同じ打設装置により行うことができず、さらに前記固定金具の重量を1.5kg以内に極めて軽量化することにより、打設作業及び装置の運搬の負担を軽減する旨が示唆されていきない。  However, in the above-mentioned document 1, as in the present invention, the anchor pin mounting bracket is elastically fixed to the tip of the driving rod of the driving device, and unlike the case where it is fixed by a bolt or the like, the fixing portion does not loosen for a long time. The fixed state cannot be stably held over a plurality of times, and a plurality of types of anchor pins can be held and cannot be performed by the same placing device according to the state of the placement position. It has not been suggested to reduce the burden of placing work and transporting the apparatus by reducing the weight to a maximum of 1.5 kg.

また、文献2(特開2002−369622号公報)には、 「止釘或いはアンカーピン或いは目串を保持及び打設するアタッチメントと、打設のための駆動力を伝達する軸とを備え、該アタッチメントは打設する対象によって交換され、該打設のための駆動力は圧縮空気或いは爆発力であり、該打設装置は止釘或いはアンカーピン或いは目串の打設後の地表からの突出量を規定する事が出来るようにした」ものであって、「主に法面保護や土壌緑化のための張芝やネット等を固定するために用いられる止釘或いはアンカーピン或いは目串の打設作業は手作業による方法であり、非常に多くの作業員を必要とし、また、作業自体が困難な法面等での打設作業は非常に困難であって、作業性の改善が望まれていた」旨説明されている。  Further, Document 2 (Japanese Patent Laid-Open No. 2002-369622) includes “an attachment for holding and driving a peg, an anchor pin or a skewer, and a shaft for transmitting driving force for driving, The attachment is exchanged depending on the object to be driven, and the driving force for the driving is compressed air or explosive force, and the driving device has a protruding amount from the ground surface after the driving of the nail, the anchor pin or the skewer. "Puts of nails, anchor pins or skewers that are mainly used to fix turf and nets for slope protection and soil greening" The work is a manual method, requiring a large number of workers, and placing work on slopes where the work itself is difficult is very difficult, and improvement in workability is desired. Is explained.

しかしながら、特許文献2においても文献1と同様に、アンカーピンの取り付け金具が打設装置の打設ロッド先端に弾性的に固定して、ボルト等により固定するのと異なり固定部分が緩むことなく長期に亘り固定状態を安定的に保持することができず、また複数の種類のアンカーピンを保持できて打設位置の状況に応じて同じ打設装置により行うことができず、さらに前記固定金具の重量を1.5kg以内に極めて軽量化することにより、打設作業及び装置の運搬の負担を軽減する旨が示唆されていない。  However, in Patent Document 2, similarly to Document 1, the anchor pin mounting bracket is elastically fixed to the tip of the driving rod of the driving device and fixed by a bolt or the like, so that the fixed portion does not loosen for a long time. The fixed state cannot be stably held, and a plurality of types of anchor pins can be held and cannot be performed by the same placing device according to the situation of the placement position. There is no suggestion of reducing the burden of placing work and transporting the device by reducing the weight to within 1.5 kg.
