[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a barricade base installed around a construction site or on a road to control pedestrian safety and vehicle traffic.

[0002]

[Prior Art]

 It is well known to install fences and other barricades on the roads around various construction sites to control pedestrian safety and vehicle traffic. By the way, the following equipment has been conventionally used as the equipment used to install these barricades.

First, as the most general one, a portable plastic one formed in a conical shape is used. That is, a plurality of cone-shaped ones are simply arranged on the road surface, and they are used by connecting them with a rope or a bar. Next, there is also a portable type in which the pipe material and the angle material are configured in a folding type.

[0004]

[Problems to be solved by the device]

 However, since all of them are portable, they have the advantage that they can be easily moved or removed, but they have the drawback that the installation position can be easily changed by a third party. That is, there was a drawback that it hindered the role of the safety fence.

Therefore, as a means for solving such a drawback, a fixed type has been devised instead of the portable type. FIG. 5 is an example thereof. As shown in the figure, a guide post 51 is erected on a concrete block 50, and casters 52 are attached to the side surfaces of the block 50. That is, the weight of the block 50 is used for fixing. In the case of relocation or removal, the upper end of the guide post 51 is held in the hand, the block 50 is tilted down, and the caster 52 attached to the side surface is used to move the block.

However, such a type has a drawback that a large number of concrete blocks and the like are naturally required when a fence or a barricade having a long span to be installed has a long span. As a result, there is a drawback that it takes time to remove the work. This invention was devised with the purpose of providing a base for installing fences or barricades that eliminates the above-mentioned drawbacks of conventional equipment.Especially, even though the installation span is long, it can be moved or fixed. It is an object of the present invention to provide a base that can be extremely easily constructed and on which stable barricades can be constructed.

[0007]

[Means for Solving the Problems]

 As a means for achieving the above-mentioned object, the present invention is configured as a barricade type base which can be easily moved and fixed by attaching a plurality of casters to a base member having a predetermined length as follows. ..

First, as the base member having the predetermined length, a groove-shaped steel material having a U-shaped cross section was used in order to increase the fixed weight, that is, to enable setting in a stable state. Then, openings are bored at regular intervals near both ends of the horizontal portion in the longitudinal direction and in the middle portion thereof, and a spindle perpendicular to the longitudinal direction of the base member is provided above each opening. The structure was pivoted.

Next, the plurality of casters are integrally attached to a support shaft pivotally supported above the respective openings of the base member via support metal fittings, and the casters support the base member while moving. It was configured to do. Further, an operation lever is attached to each of the support shafts, and when the operation lever is operated, the support shaft is rotated and the casters supporting the base member are housed in the opening of the base member and relatively moved. The stand member is characterized in that it is configured to be grounded on the road surface.

Since the present invention is configured as described above, when constructing fences or barricades by using the bases of the barricades, it is necessary to use the bases in advance, specifically, the bases. The fence, which is a component of the barricades, should be installed integrally on the base member that makes up the, or only the base should first be moved to the desired installation location, and then the fence should be assembled. The so-called barricades are used for construction.

[0011]

[Action]

 The base for barricades according to the present invention is operated by operating the operation lever attached to each support shaft to rotate each support shaft, so that each caster attached to each support shaft supports the base member. It is stored in the opening formed in the base member. At the same time, the base member is grounded to the road surface. To be precise, the lower surface of the base member is grounded on the road surface. As a result, the entire base is stably fixed on the road surface. When relocating or removing, move the operating lever to the opposite side. Then, the casters stored in both openings are turned around the fulcrum and are grounded on the road surface. That is, the base member forming the base is relatively lifted up on the road surface using the casters as a fulcrum. As a result, the entire base is movably supported on the road surface using the casters as the running wheels.

That is, the casters 3 and 3 integrally attached to the support shaft 2 through the support fitting 4 are locked in a vertical state and held. Specifically, as shown in FIG. 2, a support shaft 7a is attached to the outer surface of the right web 1c of the base member 1, and the locking metal fitting 7 is tiltable on the support shaft 7a as shown by an imaginary line. When the operating lever 5 is supported in the engaging groove portion 7b formed in the engaging metal fitting 7, the casters 3 and 3 are locked to be grounded on the road surface. Therefore, on the contrary, when the operating lever 5 is unlocked and, as shown by the phantom line in FIG. 2, it rotates about 90 degrees, the casters 3 and 3 turn horizontally about the support shaft 2 as a fulcrum, that is, The base member 1 is stored in the opening 1b provided in the base member 1, and the base member 1 is relatively grounded and fixed on the road surface.

FIG. 3 is a side view showing a schematic configuration of the base 10 configured as described above. In the drawing, as described above, the unit base 10 has casters 3 and 3 attached to the front and back of the base member 1 having a length of 5,500 mm. Then, the unit bases 10 and 10 were further connected before and after the unit base 10. FIG. 4 is a perspective view showing a state in which a fence or a fence 20 as a barricade is integrally mounted on the unit base 10 to construct a so-called barricade. Although the means for attaching the fence 20 to the base 10 is not shown in the drawing, as seen in the assembly structure such as the pipe scaffolding, the base 10 which constitutes the base 10 is preliminarily set in advance. A stanchion joint was set in advance, and it was used to assemble it integrally.
