Description

[Detailed Description of the Invention] <Industrial application field> This invention is to create a protective mass of the anchor device head for protecting the head exposed from the structure of the anchor device arranged on a slope or a retaining wall. For more information on tools, mountain retaining and retaining walls,
Protect the head of the anchor device used in parts that receive earth pressure from rust and damage, such as landslide prevention piles, sloped lattice frames, etc., underground structures built underground or buildings built on sloping ground, The present invention relates to a tool for forming a protective mass on the head of an anchor device for maintaining a stable anchoring action.

<Prior Art> When connecting ground, rock, etc. and a structure such as a block, there is a construction method in which an anchor device is arranged between the two and the structure is stabilized by the pull-out resistance of the anchor device. is there. Then, in this case, normally, the fastener of the head exposed from the structure of the anchor device is operated, that is, the nut is normally tightened to the tip of the tension material protruding to the surface of the earth to make the anchor device function. ing.

Therefore, in order to protect the exposed head of the anchor device from rust and damage, a mortar or concrete protective lump is wound around the anchor device head or oils and fats are applied.

Then, at the time of use, it is general to apply a release agent to the formwork and fix it to a structure with a numbering wire or the like, and then pour mortar, concrete or the like onto the formwork.

<Problems to be solved by the invention> Therefore, since the conventional iron formwork is heavy and the wooden formwork is bulky, it is difficult to transfer. Further, the conventional formwork can be used repeatedly, but the reuse is limited to about 5 to 10 times. Further, in order to reuse the mold, the fixing wire is cut, the mold is removed from the hardened concrete or the like so as not to be broken, and the mold is cleaned and the release agent is applied again. , It is extremely troublesome. If the same formwork is repeatedly used at the same site, not only is it troublesome, but the curing time of the placed concrete is integrated in proportion to the number of repetitions, so the construction period is prolonged. Further, since the cut number wire remains in the concrete, the number wire causes rust, resulting in deterioration of durability. In the current situation, when the formwork is stored until it is reused, it is necessary to consider the storage location and the storage method.

Therefore, there is a need for an anchor head protection device that is easy to handle and inexpensive.
