Description

Detailed description of the invention

  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.

  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).

Conventional technology

  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.

  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.

  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.

  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.
