The width of the hooking portion 12 is approximately 100 to 150 mm. In addition, the anti-slip portion 15 shown in FIG.

The reinforcing portion 21A is composed of four belt-like members 22A attached in parallel in the longitudinal direction on the rear surface of the aluminum plate portion 11A. Each strip-shaped member 22A is configured by combining a strip-shaped aluminum plate 23 and a strip-shaped steel plate 24 .

The strip-shaped aluminum plate 23 that constitutes the strip-shaped member 22A is, for example, 40 to 60 mm long and 10 to 14 mm thick. Consists of 6 to 8 mm.
The strip-shaped aluminum plate 23 is fixed to one end of the aluminum plate portion 11A by welding or the like, and has a stop portion 25 that abuts against the edge of the upper surface of the stepped portion.
The strip-shaped steel plate 24 is fixed to the other end side of the aluminum plate portion 11A by welding or the like, and has an inclined portion 26 that can be grounded on the lower surface of the stepped portion. The connecting portion between the strip-shaped aluminum plate 23 and the strip-shaped steel plate 24 is also fixed by welding or the like. Note that, in another configuration example, the strip-shaped member 22A may be composed of the strip-shaped aluminum plate 23 only.

FIG. 3(b) is a front view showing a state in which the construction site slope 10A is installed on a step portion having a height h3.
As shown in FIG. 3(b), when the construction site slope 10A is installed on a stepped portion having a height h3, the inclined portion 26 of the belt-shaped member 22 is set in contact with the lower surface of the stepped portion. , the angle β of the slope 26 is designed.

For example, the maximum height of the installable stepped portion can be adjusted by the predetermined angle α formed by the hook portion 12 . If the predetermined angle α is made closer to 170 degrees (if the angle α is made smaller), the maximum height that can be installed is increased, for example, it is possible to set the maximum value to about 300 mm. Also, if the predetermined angle α is brought close to 175 degrees (if the angle α is increased), the maximum installable height can be made smaller than when the predetermined angle α is 170 degrees.

Further, it is preferable to adjust the angle β of the inclined portion 26 together with the adjustment of the predetermined angle α. For example, as shown in FIG. 1(b), when the height of the installable stepped portion is the minimum value, the inclined portion 26 of the belt-shaped member 22A is in contact with the lower surface of the stepped portion. , the angle β of the ramp 26 may be designed.

According to the construction site slope 10A according to the above-described embodiment (2), substantially the same effects as those of the construction site slope 10 described above can be obtained. In addition, since the aluminum plate portion 11 has a thickness of about 6 mm, a width of about 450 mm in the width direction, and a width of about 1450 mm in the length direction, it can be used for relatively high steps of about 150 mm to 300 mm that occur frequently at construction sites. It is possible to appropriately bridge the structure, and it is possible for a single worker to perform the transportation and installation work on the stepped portion without excessive burden. Therefore, it is possible to provide a construction site slope that has a load resistance required for a general construction site, is sufficiently light in weight, and has a good balance between strength and weight reduction.
Further, according to the construction site slope 10A, the four strip-shaped members 22A that constitute the reinforcing portion 21A are configured by combining the strip-shaped aluminum plate 23 and the strip-shaped steel plate 24, so that the following effects can be obtained. .

Since the steel strip 24 has a higher strength than the aluminum strip 23, if the same level of strength is required, the steel strip 24 thinner than the aluminum strip 23 can be used. Machining such as cutting is easier than the strip-shaped aluminum plate 23 .
In the plurality of belt-shaped members 22A attached to the rear surface of the aluminum plate portion 11A, by using the belt-shaped steel plate 24 in the portion near the other end side of the rear surface of the aluminum plate portion 11A, the inclined portion 26 can be easily inclined. It can be carried out. Therefore, the machinability and strength of the plurality of belt-like members 22A constituting the reinforcing portion 21A can be well balanced.

Although the preferred examples of the present invention have been described above, the construction site slope according to the present invention is not limited to the above-described embodiments (1) and (2), and is within the scope of the invention. It goes without saying that various modifications are possible.
