FIG. 3 is a side view showing a state in which the inner member 30 and the outer member 40 of the stanchion 10 of FIG. 1 are combined. FIG. 4 is a side view of the tip member 50 of the stanchion 10 of FIG. The stanchion 10 is installed in a factory or on a truck bed. Although the stanchion 10 installed on the floor surface 80 in the factory is described in the first embodiment, the present invention is not limited to this.

The stanchion 10 is fixed to a floor surface 80 in the factory, extends vertically upward, and has a pointed end 51. The stanchions 10 are arranged in parallel in parallel, and guide the material suspended from above by a crane or the like so that it can be placed between the stanchions 10 so that the material can be placed so as not to collapse the load. is there.

(Structure of stanchion 10)
As shown in FIG. 1, in the stanchion 10, the bottom member 20 is fixed to the floor surface 80, the inner member 30 and the outer member 40 are stacked on the bottom member 20, and the tip member 50 is fitted to the uppermost part. .. The bottom member 20 is configured by fixing one end of a base inner member 22 to the upper surface of the base plate 21. Further, the bottom member 20 is fixed to the floor surface 80 by driving the base plate 21 into the fixing member 26 on the floor surface 80. The fixing member 26 is, for example, a bolt or a nail that is driven into the floor surface and fixed, so that the stanchion 10 does not fall down due to the load applied to the stanchion 10.

As shown in FIG. 2, in the bottom member 20, one end of the base inner member 22 in the longitudinal direction is fixed to the upper surface of the base plate 21. The base inner member 22 is, for example, a rectangular parallelepiped having a top surface 23 and a bottom surface 24 each having a length and width of 90 mm and a height of 200 mm. The side surface 25 of the base inner member 22 is formed perpendicular to the base plate 21.

As shown in FIG. 1, the outer member 40 a is fitted on the side surface 25 of the base inner member 22. The outer member 40a has a tubular shape with both ends open. The outer member 40 has, for example, a tubular shape with a horizontal cross section of 100 mm square and a height of 300 mm. The wall thickness of the tubular shape is, for example, 3.2 mm. Therefore, in the first embodiment, the fitting portion between the outer member 40a and the base inner member 22 is fitted with a gap of 1.8 mm on each side. The lower end surface 41 a of the outer member 40 a is in contact with the upper surface of the base plate 21.

When the outer member 40a is fitted to the base inner member 22, a tubular shape inside the outer member 40a on the upper end surface 42a side is a space, and the inner member 30a is fitted in the space. In other words, the height of the base inner member 22 is configured to be smaller than the height (cylindrical length) of the outer member 40a. The inner member 30 is, for example, a rectangular parallelepiped having a horizontal cross section of 90 mm square and a height of 300 mm. The inner member 30 is configured such that at least the dimension of the horizontal cross section fits into the inner peripheral surface of the outer member 40.

When the inner member 30a is fitted inside the tubular shape on the upper end surface 42a side of the outer member 40a, one end of the inner member 30a projects from the upper end surface 42a of the outer member 40a. At this time, the inner member 30a is in contact with the top surface 23 of the base inner member 22. The height of the outer member 40a is shorter than the height in which the base inner member 22 and the inner member 30a are vertically stacked. Therefore, the upper portion of the inner member 30a can be projected from the upper end surface 42a of the outer member 40a, and the outer member 40b can be further fitted. The outer member 40a and the outer member 40b are both fitted with the inner member 30a, and the upper end surface 42a of the outer member 40a and the lower end surface 41b of the outer member 40b are butted against each other and stacked, and the outer peripheral surfaces are substantially the same surface. Be assembled to be. The stanchion 10 is configured such that the outer peripheral surface from the tip end member 50 to the lowermost outer member 40a is substantially flush with each other, so that when the material is lowered along the stanchion 10, the stanchion 10 should be caught. There is no.

The height in which two outer members 40 are vertically stacked is configured to be longer than the height in which two base inner members 22 and two inner members 30a are stacked. Therefore, the outer member 40b fitted with the inner member 30a has a space inside the tubular shape on the upper end surface 42b side, and the inner member 30b is fitted into the space. In the first embodiment, the height of the outer member 40 is set to be the same as the height of the inner member 30. Therefore, when the outer member 40 and the inner member 30 are further stacked vertically above the outer member 40b and the inner member 30b, the outer member 40 fits with the upper and lower inner members 30, and the inner member 30 moves up and down. The height of the stanchion 10 can be increased by repeatedly fitting the outer member 40. In the first embodiment, the outer member 40 and the inner member 30 are stacked in three steps, and the inner member 30c protruding from the upper end surface 42c of the outer member 40c is fitted into the opening on the lower end surface 52 side of the tip member 50. A stanchion 10 is constructed.

The tip member 50 is formed such that one end of the tubular shape becomes narrower toward the tip in a side view. In the first embodiment, as shown in FIG. 1, the tip member 50 has slopes on the left and right sides in a side view. By sharpening the tip of the stanchion 10 in this way, when the material suspended by a crane is lowered to the side of the stanchion 10, the tip of the stanchion 10 can be safely operated without being caught by the material. .. Further, since the tip of the stanchion 10 is not easily caught by the material, the efficiency of the material moving work is improved. In the first embodiment, for example, the tip member 50 is set to have a horizontal cross section of 100 mm square and a height of 600 mm. The tip end portion 51 is formed in a pointed shape as shown in FIG. 1, but the lower end face 52 side is cylindrical so that the inner member 30 can be fitted therein like the outer member 40. ing.

FIG. 5 is a side view showing a state in which the numbers of the outer member 40 and the inner member 30 constituting the stanchion 10 of FIG. 1 are changed. In FIG. 1, the stanchion 10 is configured by stacking each of the outer member 40 and the inner member 30 in three stages, but the outer member 40 and the inner member 30 are stacked in two stages in FIG. In FIG. 5B, one stage is provided, and in FIG. 5C, there is no stage (that is, 0 stage). With such a configuration, the height of the stanchion 10 can be easily changed by changing the numbers of the outer member 40 and the inner member 30. Further, when changing the height of the stanchion 10, it is sufficient to prepare a plurality of outer members 40 and inner members 30 having the same shape and the same size, and it is necessary to prepare parts having different shapes and different sizes according to the height. Therefore, it is possible to share parts with other stanchions 10 without cost.

As shown in FIG. 3, the connecting portion between the outer member 40 and the inner member 30 may be fixed by the fixing member 90. The fixing member 90 may have a structure in which, for example, a bar member having a threaded end is passed through both the outer member 40 and the inner member 30 and a nut is tightened from the end part of the bar member. Since the fixing member 90 protrudes from the surface of the stanchion 10, it is preferable to provide the fixing member 90 on the side surface where the material to be placed does not face. Further, the connecting portion between the tip member 50 and the inner member 30 may be similarly fixed by the fixing member 90.

In the first embodiment, the structure of one stanchion 10 has been described. However, for example, when laying a material in a factory, a plurality of stanchions 10 are installed at intervals, and a space between the stanchions 10 is provided. Be sure to put in the materials. The space between the plurality of stanchions 10 can be appropriately set according to the width dimension of the material to be placed.
