Description

[Detailed description of the invention] [Industrial application field] The present invention is a road sign that has an elongated conical shape and a square seat plate at the bottom to indicate a construction area during road construction. It concerns a device for continuous installation.

[Conventional technology]

Conventional road signs are mostly long conical shaped with rounded tops, and when road construction is underway to indicate a construction zone, a large number of them are placed on the road at appropriate intervals. However, when installing them, workers have to carry them one by one,
Usually, a large number of them are loaded onto a car, and workers get off the car and carry them around at each installation location.

[Problem that the invention attempts to solve]

However, in the conventional method as mentioned above,
It is extremely time-consuming and inefficient, and especially when the work area is long, such as when working on a highway, a large number of road signs are loaded onto a car, and workers have to place each sign at each location. As mentioned above, the work efficiency is low, and there is a growing demand for improvements in the installation method.

[Means for solving problems]

The present invention was developed with the aim of solving the problems of the prior art as described above, and its structure consists of a road sign with a long conical shape and a rectangular seat plate integrally provided around the bottom of the road sign. A large number of holes are provided in the sign for insertion of pipes, etc., and a large number of the holes are stacked on top of each other, and at least two stoppers are provided in the insertion hole of the sign, which become larger than the hole when inflated or expanded, and become smaller than the hole when contracted or narrowed. The present invention is characterized in that a pipe or the like is inserted through the road sign and the road sign is sequentially dropped and installed using a gravity drop method by operating the stopper.

[Effect]

That is, the present invention has a hole through which a pipe or the like can be inserted at the top of a conventionally known road sign, and a large number of holes are stacked on top of each other. A pipe or the like provided with at least two stoppers smaller than the hole is inserted into the insertion hole with the stopper facing down, and loaded into a car with the lower stopper of the lowest sign inflated or expanded. When the sign reaches its installation location, if the lower stopper is contracted or closed from above the vehicle, the lowermost sign will fall due to its own weight, and the upper stopper will expand or expand, causing other signs to fall. In this state, the lower stopper of the newly placed lowest sign is inflated or expanded, and the upper stopper is contracted or narrowed to keep it in a standby state. When they reached the next installation location, they performed the same operations as before, allowing them to place the signs one after the other.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

A is a road sign in which a rectangular seat plate 2 is integrated at the bottom of a long conical body 1 and a through hole 3 is bored at the top for passing a pipe, etc. A weight plate is attached to the back of the seat plate 2. 4 is pasted on the road sign A, and when a large number of these road signs A are stacked, the inner wall of the upper one does not come into close contact with the outer wall of the lower one.

B is a stopper member having a pipe shape and provided with spherical stoppers 5, 5a that expand and contract at its lower part;
When the stopper 5 is expanded, the stopper 5a is contracted, and when the stopper 5 is contracted, the stopper 5a is
For example, when two road signs A are stacked and the stopper member B is inserted into their through hole 3, the stopper 5 is expanded. It is assumed that the stopper 5a is positioned within the top of the lower marker, and the stopper 5a is positioned within the top of the upper marker in the contracted state.

This stopper member B is used when a large number of road signs A are stacked on the loading platform of a car and installed one after another on the road. lowest road sign A
1, the stopper 5 is inflated to standby, and when the road sign A is to be installed, the stacked road signs are placed at the installation location, and the stopper member B is operated to deflate the stopper 5. At the same time, when the stopper 5a is inflated and the road sign group is pulled up, the lowest road sign A1 is left at the installation location due to its own weight, and the new lowest road sign A1 is installed until it reaches the next installation location. To continuously and efficiently operate a road sign A by sequentially repeating the work of contracting a stopper 5a in a road sign A2, moving it to a road sign A3 above it, and inflating a stopper 5 to put it in a standby state. This is possible.

B' is another example of a stopper member using a link mechanism, in which the lower end of the stopper link 7 is attached to the lower end of the operating lever 6, the upper end of the stopper link 7a is attached to an appropriate location of the operating lever 6, and the upper end of the link 7 is attached to the lower end of the operating lever 6. The lower end of the link 7a is connected by a connecting rod 8, and when the link 7 is in the expanded state, the link 7a
is in a narrowly closed state, and if the operating rod 6 is moved downward in this state, the link 7 is narrowly closed and the link 7a is expanded.

Therefore, similarly to the stopper member B, the stopper link 7 is set in the expanded state so that it is within the lowest road sign A1 and is in a standby state, and when the road sign A reaches the place where it is to be installed, it is stacked. Place the road sign at the installation location, operate the operating lever 6 to narrow the link 7 and expand the link 7a to pull up the road sign group, and the lowest road sign A1
is left as it is at the installation location due to its own weight, and before reaching the next installation location, link 7a in the new lowest road sign A2 is narrowed and moved to the road sign A3 above it. The road signs A are successively installed by sequentially repeating the work of expanding the links 7 and putting them in a standby state.

[Effect of idea]

Since the present invention is as described above, road signs can be installed continuously and efficiently, making it extremely convenient and suitable as a road sign installation device for road construction.
