Except for the above embodiment, it is not always necessary to provide a narrow notch (2) in the long base (1), and the base (1) is not provided with the fitting hole (5), and the column is fitted. The tube (4) may be welded to the upper surface of the long foundation (1). Further, the fitting hole (5) may be provided in a part or all of the part (3) other than the narrow notch (2).

When a car or the like collides with the guardrail (11), the impact is received by the weight of the long base (1) and dispersed to another connected long base (1). .

When the long base (1) of this embodiment is made into scrap, it can be melted and cut into small pieces from the narrow notch (2) and reused as an iron raw material.

FIGS. 9 to 14 show another embodiment of the present invention. In this embodiment, the main body (31A) of the long temporary guardrail foundation (31) is made of a channel steel having a U-shaped cross section, and the foundation main body (31A) is provided with mounting holes (32) at predetermined intervals. An intermediate block (33) is mounted in the mounting hole (32) and fixed by welding. The intermediate block (33) is manufactured by fusing or cutting a steel ingot, and is provided with a fitting hole (35) for a column fitting cylinder (4) from the front surface and a fence (1) from the rear surface.
A fitting hole (36) for the column (19A) of 9) is provided. As shown in FIG. 12, reinforcing beams (37) are provided on both sides of the base body (31A) where the intermediate block (33) is attached.

One end of the base body (31A) is cut out, and a hook block (38A) having a hook (38) protruding therefrom is fixed, and the other end is cut out to form an engaging groove into which the hook (38) fits properly. The groove block (39A) penetrating (39) is fixed. Then, as shown in FIG. 13, both sides of the block (38A, 39A) have reinforcing beams (40, 4).
Reinforced by 0). The hook (38) has a flat inverted trapezoidal shape, and the back wall (391) of the engagement groove (39) is curved in an arch shape. Further, a through hole (41) for the anchor (14) is provided at a predetermined position of the base body (31A).

The basis (31) of this embodiment is the basis (1) of the previous embodiment.
Much lighter, the length is usually set to 1.5-4m, in which case the weight is approximately 100-600kg. Therefore, it is easy to heat, and it is easy to apply galvanizing treatment for rust prevention, rust prevention coating treatment, and the like.

The basis (31) of this embodiment is also the basis (1) of the previous embodiment.
Same as for example on the side of the road, adjacent foundation (31)
Comrades fit the hooks (38) of the hook block (38A) at one end into the engaging grooves (39) of the groove block (39A) at the other end by connecting them from above, and further connect the anchor (14) with the anchor through hole (41). And fixed by driving into the ground. As described above, since the inner wall (391) of the engaging groove (39) of the groove block (39A) is curved in an arch shape, the base (31) can have a maximum of 1 at the connecting portion.
It can be bent to 0 °, so that the foundation (31) of this embodiment can correspond to the curve of a general road. And as in the previous embodiment, the support fitting cylinder (4) of the foundation (31)
The support (12) of the guardrail (11) is fitted to the support, and the support (19A) of the fence (19) is fitted to the fence support fitting hole (36).

In addition to the above embodiment, as shown in FIG. 15, the mounting hole (32A) of the base body (31A) is fitted into the mounting hole (4) of the column fitting tube (4).
(45), and a bracket (46A) having fitting holes (46, 46) for fence posts (19A, 19A) separately from the intermediate block (43). You may. In this case, the fence post fitting holes (46, 46) outside the intermediate block (43) are projected from the basic body (31A). Further, the intermediate block (43) may be fixed on the base body (31A) or below the base body (31A) without providing the mounting hole (32A) in the base body (31A). Further, in this embodiment, as shown in FIG. 16, H is used as the base body (51A).
Shaped steel may be used.

[0019]

According to the present invention, the positioning of the foundation is easy, and the connection between the foundations does not require a connecting rod, so that the operation can be performed extremely easily. In particular, the work of installing the temporary guard rail becomes simple and easy.
