And in such a column stand, a gripping recess is formed on the opposing inner wall surface of the recessed groove to facilitate gripping, and the safety during moving work is further enhanced. According to the invention of claim 2, the surface of the stand main body is a surface having no edges or recesses to ensure safety and to be preferable in terms of design. A night sign that is clearly displayed at night is provided as the invention of claim 4, and an identification sign such as a letter is projected on the upper surface of the stand body, while a position corresponding to the identification sign is provided on the groove bottom of the groove. Has a shallow groove, and when a plurality of the column stands are crossed up and down, the identification mark of the column stand on the lower side is placed in the shallow groove on the column stand on the upper side. They are the ones to the invention of claim 5. Further, the stand main body made of spheroidal graphite cast iron is defined as the invention of claim 6, and the stand body whose surface is galvanized is defined as the invention of claim 7.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.
Reference numeral 1 denotes a stand body made of a hard heavy material such as spheroidal graphite cast iron, and the surface thereof is galvanized. The stand body 1 is a block body having a substantially rectangular outer shape whose left-right width is longer than the front-rear width and is edge-dropped when viewed from above, and is vertically extended at the center portion of the outer surface on the opposite long side. Arc-shaped bulging portions 2 and 2 as shown in the figure bulged into a semi-column shape are formed, and a pair of column insertion holes 3 and 3 are formed in the vertical direction on the left and right bisector of the stand body 1. Has been. Further, the both sides of the long side are left as short legs 1a and 1a at the bottom of the stand main body 1, and the groove width is substantially equal to the width of the short side of the stand main body 1, and the opposite groove wall surface Concave grooves 5 having arc-shaped concave portions 4 and 4 corresponding to the arc-shaped bulging portions 2 and 2 are provided in the front-rear direction, and the arc-shaped concave portions 4 and the concave grooves 5 alternately form a plurality of support columns. When crossed and stacked vertically, the upper part of the lower column stand is fitted into the concave groove 5 of the upper column stand, and at the same time the arcuate bulging portions 2 and 2 of the upper column stand are It is assumed that a stable multi-stacked state is obtained by engaging with the arcuate recesses 4, 4 of the column stand on the side.
[0006]
In addition, the concave portions 6 and 6 for the hand are formed in the central portion of the groove wall surfaces of the groove 5 facing each other, and the required surface of the stand body 1 receives and reflects light at night. A night sign 7 is provided by applying a reflective tape or a reflective plate, applying a reflective paint, an array of lamps, or any other means. Further, on the upper surface of the stand body 1, an owner's name, precautions and other arbitrary intentions are provided. While the identification mark 8 such as characters for displaying is projected, the above-mentioned identification mark 8 is provided even when a plurality of support stands are vertically stacked on the groove bottom of the groove 5 as described above. A shallow groove 9 is provided so as to be stably accommodated.
[0007]
In such a configuration, a plurality of the units are installed on the ground at a predetermined interval, and the columns are inserted into the column insertion holes 3 formed on the left and right bisectors of each stand body 1. Although it is the same as a conventional column stand made of heavy materials, it is the same as a column stand made of a heavy material, and it is the same as that of a conventional support stand made of heavy materials. One of the left-right width and the front-rear width is longer than the other, and is made of a heavy weight material such as spheroidal graphite cast iron in which short legs 1a, 1a having a groove width separated by a concave groove 5 are formed at the bottom. Therefore, if it installs with the short leg parts 1a and 1a of both sides, the very stable installation state will be obtained.
[0008]
Moreover, the stand body 1 in which one of the left and right widths and the front and rear widths is longer than the other has the arcuate bulges 2 and 2 formed at the center portions of the outer surfaces on the opposite long sides, and the bottom portion has a groove width. The stand body 1 is substantially equal in width to the short side, and a groove 5 having arcuate recesses 4 and 4 into which the arcuate bulges 2 and 2 can be fitted is provided on the opposing groove wall surface. Therefore, when a plurality of the column stands are alternately crossed and overlapped vertically, the concave groove 5 of the column support on the upper side and the upper part of the column stand on the lower side are the arc-shaped recess 4 and the arc-shaped bulging portion. Since they are fitted under the engagement with No. 2, they are stacked in a stable state and are convenient for storage and transportation.
[0009]
Further, by setting the surface of the stand main body 1 to be a surface having no edge, other objects are not damaged by the edge, and the concave recesses 6 and 6 are formed on the opposite groove wall surfaces of the concave groove 5. Therefore, when the stand body 1 is lifted, it can be lifted accurately without dropping by using the recesses 6 and 6 for the hand, and is excellent in safety. Safety at night can be ensured by providing a night sign 7 on the required surface of the stand body 1 by applying reflective tape or reflector, applying reflective paint, arranging lamps or any other means. .
[0010]
Furthermore, it is more convenient to use an identification mark 8 such as an owner name, precautions, or other characters for displaying an intention of intention on the upper surface of the stand main body 1. In the case where the mark 8 is provided, it is preferable to provide a shallow groove 9 at a position corresponding to the identification mark 8 on the groove bottom of the groove 5 so that the stability at the time of stacking is not impaired. As long as the stand body 1 is made of a hard heavy material, concrete, gray cast iron and other materials are not particularly limited. It can be made into a product with a better appearance in terms of safety management, work, recycling, etc. at the work site, especially if the surface is galvanized. And it is excellent in more appearance and durability.
[0011]
【The invention's effect】
As is apparent from the above description, the present invention is such that the stand main body is formed with an arcuate bulging portion at the center portion of the outer side on the long side where either one of the left-right width and the front-rear width is longer than the other and faces. Since the groove width is substantially equal to the short side width of the stand body, and the opposing groove wall surface is a block body provided with a concave groove provided with an arc-shaped concave portion capable of fitting the arc-shaped bulged portion, Compared to this type of conventional stand, it has a good appearance and is excellent in safety and durability.In addition, it is possible to stack multiple pieces in a stable state by alternately crossing multiple pieces, so it is easy to store and transport, It also has excellent stability.
Therefore, the present invention solves the problems of this type of conventional column stand, combined with the advantage that it can be mass-produced inexpensively because of its simple structure and easy manufacture, and it contributes to the industry. is there.
