BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to examples. However, the examples are merely representative examples, and the present invention is limited by the following examples unless departing from the gist thereof. Instead, it can be implemented with various design changes.
[0014]
FIG. 1A is a schematic front view schematically showing a column structure 10 according to a first embodiment of the present invention, and FIG. 1B is a diagram showing the column structure 10 bent. It is a schematic front view which shows a state typically. FIG. 2 is a main part front view in which main parts of the support structure 10 are enlarged.
[0015]
In the figure, a strut structure 10 includes an anchor 18 (lower strut 21) embedded in a foundation 12 formed by casting concrete on a roadside, an upper strut 22 having a reflector 13 attached to an upper end thereof, The reflecting mirror 13 is configured so that the bird's-eye view angle and the left and right angles can be adjusted.
[0016]
The upper strut 22 is formed of a cylindrical wooden round bar formed by processing a thinned material, and a lower end portion thereof is inserted into a receiving portion 14 provided at an upper end of the connecting member 15 and screwed if necessary. It is configured to be connected and fixed by fixing.
[0017]
However, the raw material of the upper support 22 is not limited, and the design can be changed as necessary, such as forming a metal, for example, iron or aluminum or plastic cylinder, prism, circular pipe, square pipe, or the like. I do.
[0018]
The connecting member 15 includes a connecting round bar 15a that bends first when a large external force acts upon a collision of a vehicle or the like (claims 1 and 2). A male screw is screwed into a lower end portion of the connection round bar 15a, and is fixed by being detachably screwed to an anchor member 18 (functioning as a lower support 21) embedded in the concrete foundation 12. . However, the connecting means for removably connecting and fixing the connecting member 15 to the upper support 22 and the lower support 21 can be implemented with various design changes.
[0019]
The support structure 10 always maintains an upright state, but when a large external force such as a collision of a vehicle acts on the upper support 22, the connecting member 15 bends (bends) first and selectively. External force can be absorbed and buffered without self-restoration.
[0020]
After the accident, when the upper support 22 is returned to the original upright state by hand, the bent state of the connecting member 15 can be restored to the original state, and the repair is completed by adjusting the mounting angle of the reflector 13. . If the connecting member 15 is severely damaged that is difficult to restore, the original state can be easily restored by replacing only the connecting member 15 with a new connecting member 15 and reassembling. Therefore, the restoration work is significantly simplified as compared with the conventional restoration work that had to be rebuilt from the foundation, and the construction cost can be reduced.
[0021]
FIG. 3 is a cross-sectional view of a main part schematically showing a column structure 30 according to a second embodiment of the present invention.
[0022]
This support structure 30 is characterized in that the central part of the connecting member 15 is formed of a connecting round bar 15b whose diameter is reduced, and an anchor provided at the top end of a concrete or wooden base member 23 built on the ground X. The other configuration is the same as that of the support structure 10 of the first embodiment except that the lower end of the connecting member 15 is detachably screwed and fixed to the member 18 (the lower support 21). The configuration is substantially the same.
[0023]
Therefore, even if a large external force acts on the column structure 30 of the second embodiment, only the central portion of the connecting round bar 15b is preferentially and selectively bent (bent) without self-restoring. Can be absorbed and the restoration operation can be completed in the same procedure as that of the column structure 10 of the first embodiment, so that the restoration operation can be remarkably simplified and the repair work cost can be reduced. Further, after the accident, there is no need to dig the foundation member buried in the soil and replace it with a new foundation member, and if the connecting round bar 15b is severely damaged that is difficult to recover, the connection is made. It is a matter of course that the original state can be easily restored by replacing only the member 15 with a new connecting member 15 and reassembling.
[0024]
The material, dimensions, and the like of the connecting member 15 and the connecting round bars 15a and 15b are appropriately changed in design so as to obtain the most appropriate absorption buffer effect in consideration of the type, speed, and weight of the assumed collision vehicle. Of course.
[0025]
Next, FIG. 4 is a main part front view schematically showing a column structure 40 according to a third embodiment of the present invention.
[0026]
In the figure, the support structure 40 is built upright on a roadside or in a parking lot by embedding the lower end of the lower support 21 in the ground. The lower support 21 and the upper support 22 are both made of metal pipes, and the connecting member 16 has a plurality of vertical slits (through holes) 16a formed in the center and thread grooves 16b at both ends. And a metal pipe having Further, the connecting members 16a and 17b are detachably connected to the screw grooves 21a and 21b provided at the upper end of the lower support 21 and the lower end of the upper support 22, respectively, at both ends of the connecting member 16. Screw grooves 16b, 16b for screwing are provided.
[0027]
Therefore, even if a large external force such as a collision of a vehicle acts on the column structure 40 of the third embodiment, the connecting member 16 is formed by a plurality of slits (through holes) arranged in the center in the vertical direction. Since the slit 16a is formed of a hollow pipe, the position of the slit is weakened, so that this portion bends (bends) first and selectively to absorb and buffer external force.
[0028]
After the accident, the restoration work can be completed by the same procedure as that of the column structure 10 of the first embodiment, and the restoration work can be remarkably simplified, and the repair work cost can be reduced. In addition, when the connecting member 16 is severely damaged that is difficult to restore, it can be easily restored to the original state by replacing it with a new connecting member 16 and newly reassembling. An effect can be obtained.
[0029]
The material, dimensions and shape of the connecting member 15, and the width and length of the slit (through hole) 16a, the number of holes to be drilled, and the like are most appropriate in consideration of the type, speed, weight, and the like of the assumed collision vehicle. It is a matter of course that the design is appropriately changed so as to obtain the absorption buffer effect.
[0030]
Next, FIG. 5 is a main part front view schematically showing a strut structure 50 according to a fourth embodiment of the present invention.
[0031]
In the figure, in the support structure 50, the raw material of the connecting member 55 is a pipe or a rod made of gypsum, cement, stone, plastic, or the like, and a support provided at the lower end of the upper support 52. The distal end portion of the connecting member 55 is inserted and fitted in the portion 53 and the anchor 51b (corresponding to the lower support 51) embedded in the foundation 51a, and is removably connected. When a large external force such as a collision of the vehicle with the body 50 is applied, the connecting member 55 is preferentially and selectively broken.
[0032]
Therefore, after an accident, the original state can be easily restored by replacing the connecting member 55 with a new connecting member 55 and newly reassembling. Therefore, there is no need to rebuild from the foundation, and the restoring work is greatly simplified. Moreover, construction costs can be reduced.
[0033]
As described above, the typical embodiment according to the present invention has been described. For example, as shown in a perspective view of a main part in FIG. 6, the connecting member 65 is provided with a plurality of vertical slits 65 a at a central portion, The female screw 65b is provided on the bottom surface, and the receiving portion 62a for inserting and preferably screwing and fixing the upper support column 62 made of wood is constituted by a steel pipe provided at the upper end by a well-known connecting means. Needless to say, it may be configured to be detachable.
[0034]
【The invention's effect】
