Description

  The present invention relates to a scaffold unit that is used to construct a walking part that serves as a scaffold when performing operations such as mowing weeds on slopes such as ridge slopes and banks.

  When weeds grow on the shores of paddy fields, they become a hotbed for pests that damage crops such as rice. Agricultural workers who manage the shores cut grass weeds on the slopes and banks, but some weeds grow fast and have strong reproductive power. Since the new shoots and side shoots grew immediately to form a large community, the mowing work had to be repeated many times between the time of rice planting and the harvesting of rice.

  However, the slopes in the mountainous terraced areas are often steep slopes, and when you walk across the slopes or stand on the slopes and operate an engine-equipped brush cutter, The burden on the workers was heavy, and there was a risk of slipping and falling when the feet were slipped. Especially in mountainous areas, large ridge slopes with a length of several tens of meters or more have been created by infrastructure development, and the slopes are steep with a slope of about 40-50 °.

  On the other hand, agricultural workers are aging, and the mowing work on the slope becomes very severe and there is a high risk of causing a sliding accident. Therefore, in order to reduce the labor of mowing work on a large ridge slope and prevent a sliding accident, it is desirable to provide a path or step that serves as a scaffold for mowing work across the slope. Yes.

  In order to solve this problem, the unit body of the dog running construction unit on the slope such as the shore is a horizontally long top plate part with a plurality of pile driving holes and one long side of the top plate part. A first leg plate portion that forms a short leg along the top and a second leg plate portion that forms a long leg along the other long side of the top plate portion. A dog running construction unit is disclosed which is configured to be fixed to the slope of the soil by a resistance driven from a pile driving hole provided in (see Patent Document 1).

Utility Model Registration No. 3151694

  The dog running construction unit described in Patent Document 1 is made of hard plastic, is formed into a box shape with an open bottom, and a plurality of anchors that pierce the soil slope at the lower ends of the first and second leg plate portions The protrusion is formed so as to protrude downward, and a flange serving as a stopper that restricts the depth at which the anchor protrusion pierces the slope of the soil is formed protruding sideways.

  The dog running construction unit having such a configuration is restricted from soil entering the inner side from the flange surface, creating a space, so even if the dog running construction unit is held on the slope with an anchor, it is exposed to wind and rain. If the bottom of the dog-running construction unit installed on the slope with rainwater is eroded, the dog-running construction unit becomes unstable with respect to the slope, and the farmer stands on the slope and stands on the engine. When manipulating etc., there was a risk that the foot would slip or fall down.

  The shoreline mowing scaffold unit of the present invention has been made to solve the above-mentioned problems, and can be used as a shoreline mowing scaffolding unit stably for a long time after being constructed on a slope. It is.

The anchorage unit for mowing the slope slope of the present invention is a scaffold unit that is installed on a slope of a slope and has a width that allows a person to walk in a direction perpendicular to the slope, and the scaffold unit has a predetermined length. And an anchor bolt for fixing the scaffold to the slope of the slope.
The scaffold is a pedestal on which one side of a triangular prism having a predetermined length is placed on the slope, and the pedestal is provided with a groove having a predetermined width along the central axis on the long side, and both sides of the groove. Has a protrusion embedded in the slope.
The other two sides of the triangular prism having a predetermined length are used as a walking surface, and a plurality of through holes penetrating the pedestal from any one of the walking surfaces are provided, and the scaffold is used as a slope of the slope. A plurality of anchor bolts to be fixed to is inserted.

  The scaffold is formed such that the pedestal has a predetermined thickness and the width of the pedestal extends in a direction perpendicular to the long side of the triangular prism. Further, the scaffold is formed by separating a pedestal and a walking surface, and a bottom surface of the walking surface is straddled on the surface of the pedestal, and the surface of the pedestal has a long side of the pedestal surface. A convex wall having a predetermined width is provided along the central axis, and a concave groove having a predetermined width is formed on the bottom surface of the walking surface along the central axis on the long side of the walking surface. And

  The scaffold is characterized in that the surface side of the pedestal at the part where the bottom surface of the walking surface extends is provided with a gradient with respect to the surface of the pedestal. Further, at least the pedestal of the scaffold is formed of reinforced concrete.

  The anchorage unit for cutting the shore slope of the present invention is strong because it is formed of reinforced concrete, and since the projections embedded in the slope of the slope are projected downward on both sides of the long side of the pedestal, When the scaffold unit is placed on the slope, the protrusion can bite into the slope and be stably fixed. In addition, since the hypotenuse of the triangular prism forming the walking part is formed at a different angle, if the walking surface is reversed and installed, the walking surface can be made more horizontal in accordance with the slope angle of the slope. Can be installed. Furthermore, a predetermined slope is formed on the surface of the pedestal according to another embodiment that is in contact with the walking portion. Thereby, the walking surface can be set closer to the horizontal by applying the scaffold unit for mowing the mower according to the slope of the slope.
