[Technical field to which the invention belongs]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-weight slope body for vehicle travel that is installed at a stepped portion on a travel path of a vehicle such as heavy machinery in a construction site such as civil engineering work and facilitates travel of the vehicle such as heavy machinery.
[0002]
[Prior art]
Conventionally, when driving heavy equipment and other vehicles on heavy work sites, carry high-quality earth and sand to the work site with the steps, fill and compact to match the level difference of the steps. A method is used in which a slope body is formed and run on the slope body.
[0003]
However, with this method, when the work is finished and the vehicle is no longer required to travel, it is necessary to remove the soil that has been brought in and embanked to eliminate the level difference. In addition, when there are steps in other parts of the work site, it is necessary to carry in the earth and sand to the places where there are steps and perform embankment to form a slope body that matches the level difference of the steps.
As described above, it takes a lot of labor to form and remove the embankment and to carry in and out the high quality earth and sand, and there are also problems from the work environment such as dirt on the work site due to the earth and sand that has been brought in.
[0004]
[Problems to be solved by the invention]
In order to solve these problems, a method can be considered in which a block body is made of a material having rigidity sufficient to withstand a vehicle load, and a slope body made of the block body is disposed in the step portion to eliminate the step. In particular, in the case of a step with a large difference in height, the weight of the block body becomes heavy and handling becomes troublesome.
In addition, in order to construct a slope body corresponding to various steps with different heights, there arises a problem that it is necessary to prepare and prepare several types of block bodies adapted to these steps.
[0005]
The present invention has been made to solve the above-mentioned problems, is lightweight, easy to handle, can cope with height differences of various steps, and is safe and has no problem from the work environment. A lightweight slope body is provided.
[0006]
[Means for Solving the Problems]
The present invention forms a front unit of a parallel hexahedron panel formed of a hard foam resin, a base unit formed on an inclined surface, and an intermediate stage unit formed of a panel similar in shape to the base unit, and A triangular pentahedral top block body unit having an inclined surface with the same inclination angle as that of the base unit and the intermediate stage unit is formed on the front surface, and the base unit, the intermediate stage unit, and the top block body unit are inclined. It is that it was constructed as a light-weight slope body for vehicle travel by sequentially stacking to be flush with each other.
[0007]
Further, the entire surface of the inclined surface of each unit is reinforced with a plate-shaped inclined surface reinforcing material having rigidity, and each corner portion is reinforced with a corner reinforcing material such as an angle material.
[0008]
Further, the edge of the corner reinforcement on the upper and lower surfaces of each unit is projected outward from the unit, and the projected reinforcement edge is connected with a connector such as a bolt or a clip so that the units are integrated. This is a fixed structure.
[0009]
Moreover, it is set as the structure which provided the protrusion for ground fixation in the bottom face of the base unit of the lowest step.
[0010]
The lightweight slope body for vehicle travel according to the present invention is:
(1) In constructing the slope body, a base body unit, intermediate stage unit and top block body unit formed from the hard foam resin that has been transported are stacked in sequence on the front of the step part to construct a slope body that eliminates the step. Since it is set as the structure to do, a slope body can be easily formed only by stacking a lightweight unit easily by human power.
[0011]
(2) In constructing the slope body, each unit is stacked and formed, so that a slope body corresponding to the height difference of various steps can be formed.
(3) The inclined surface of each unit is reinforced with a rigid plate-shaped inclined surface reinforcing material, and each corner portion is reinforced with a corner reinforcing material such as an angle material, so that it can sufficiently withstand the vehicle load. The unit will not be broken and the corners will not be missing.
(4) Since the ends of the corner reinforcements on the top and bottom of the unit are projected outside the unit and connected between each unit with bolts and clips, etc., the unity of the slope body is maintained, so each unit There is no gap between them.
(5) Since the ground fixing protrusion is provided on the bottom surface of the lowermost base unit, the slope body is firmly fixed to the ground and does not move.
