Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a column used when a sheet or the like is stretched as a temporary enclosure around a site to be a construction site.
[0002]
[Prior art]
Generally, at a construction site, in order to prevent materials etc. from protruding beyond the boundary with the adjacent land, or to prevent outsiders from inadvertently entering the construction site, In many cases, temporary enclosures are provided by placing a sheet around the site. As such a temporary enclosure 51, for example, as shown in FIG. 6, a column 54 is erected at each corner 53 of the site 52, and a long mesh sheet 55 is stretched between the columns 54. A structure surrounding the site 52 is known.
[0003]
And as the said support | pillar 54 used for such a temporary enclosure 51, what is shown in FIG. 7 is known. This is made up of a column main body 56 formed in a rod shape, a fixed pile guide 57 that is fixed substantially parallel to the column main body 56 in the vicinity of the lower end portion of the column main body 56, and two columns up and down, and a column main body 56. The upper end 58 is coupled to the predetermined height position, the support pile guide 60 is provided at the lower end 59, and the two support legs 61 are inclined at a predetermined angle so as to spread downward with respect to the column main body 56. Is provided.
[0004]
Here, at the connecting portion between the upper end portion 58 of the support leg 61 and the column main body 56, two connecting plates 62 projecting sideways are provided at substantially right angles to each other at a predetermined height position of the column main body 56. The upper end portion 58 of the support leg 61 is fixed to each of the two connection plates 62. That is, the two support legs 61 are disposed substantially at right angles to each other. The fixed pile 63 is inserted into the fixed pile guide 57 and driven into the ground 64, and the support pile 65 is also inserted into the support pile guide 60 of each of the two support legs 61 and driven into the ground 64. The support 54 is erected.
[0005]
A tensile force by the mesh sheet 55 stretched thereon acts on the column 54 standing upright in this way. Therefore, in order to efficiently support the column 54 against the tensile force of the mesh sheet 55 and not to disturb the construction work, the support leg 61 is parallel to the direction in which the tensile force acts. In such a way, they are arranged in parallel along the inside of the mesh sheet 55.
[0006]
[Problems to be solved by the invention]
However, such a conventional support 54 has the following problems. That is, the site that is the construction site is not always rectangular at all corners such as rectangles and squares, and there are sites that have acute or obtuse corners. Since the conventional support 54 is fixed so that the two support legs 61 are substantially perpendicular to each other, as described above, when the support is placed at such an acute or obtuse corner, the support legs There is a problem that 61 cannot be arranged in parallel along the inside of the mesh sheet 55 and the support 54 cannot be efficiently supported against the tensile force. In addition, when arranged at the acute corner 53, the support leg 61 and the mesh sheet 55 come into contact with each other, and the mesh sheet 55 cannot be neatly stretched, and is arranged at the obtuse corner 53. In this case, there is a problem that the supporting leg 61 cannot be suitably used, for example, because the supporting leg 61 is disposed so as to protrude to the center side of the site 52 and obstructs the construction work.
[0007]
The present invention has been made in view of the above problems, and by allowing support legs to be arranged in parallel along the inside of a temporary enclosure sheet or the like at corners of arbitrary angles, An object of the present invention is to provide a support column that can be suitably used regardless of the shape of the site to be a construction site.
[0008]
[Means for Solving the Problems]
Specific means for solving the above technical problems are as follows. That is, the support column according to claim 1 includes a support column main body formed in a rod shape, a fixed pile insertion pipe fixed substantially parallel to the support column main body in the vicinity of the lower end portion of the support column main body, and the support column main body. Two support leg insertion pipes fixed substantially parallel to the column main body at a predetermined height position, and an upper end support shaft part inserted through the support leg insertion pipe are rotatably coupled to each other, Two support legs inclined at a predetermined angle with respect to the column main body, and a fixture for fixing the upper end support shaft portion of the support leg inserted through the support leg insertion tube at an arbitrary angle. It is a feature.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the support | pillar 1 which concerns on this invention is demonstrated based on drawing. FIG. 1 is a perspective view of a support 1 according to an embodiment of the present invention as viewed from the front, FIG. 2 is a perspective view of the support 1 as viewed from the side, and FIG. 3 is a plan view of the support 1. As shown in these drawings, a column 1 according to an embodiment of the present invention is fixed to a column main body 2 formed in a rod shape and substantially parallel to the column main body 2 in the vicinity of the lower end portion of the column main body 2. Fixed pile insertion tube 3, two support leg insertion tubes 4 fixed substantially parallel to the column main body 2 at a predetermined height position of the column main body 2, and an upper end inserted through the support leg insertion tube 4 Two support legs 6 that are rotatably coupled around the support shaft portion 5 and are inclined at a predetermined angle with respect to the column main body 2 are provided. This will be described in more detail below.
[0012]
The column main body 2 is a column portion that becomes the main body of the column 1 and is formed in a rod shape. Here, in order to reduce the weight, etc., it is constituted by a circular pipe. It is preferable that the height of the column main body 2 is slightly higher than the height of the mesh sheet 9 stretched around the site 8 (see FIG. 5) in the temporary enclosure 7 configured using the column 1. This height is usually around 1.5 m. It is preferable to provide a bottom plate 10 at the lower end of the column main body 2 in order to prevent clogging with sand and mud. Although not shown, it is also possible to provide a jack having a height adjusting function at the lower end of the column main body 2. Thereby, even when the ground surface 11 has some unevenness, it is possible to adjust the height of the column 1 to match the height of the adjacent column 1.
[0013]
In addition, attachment hooks 13 are provided at the upper end and lower end of the support body 2 to wrap the fastening band 12 used when attaching the mesh sheet 9 to the support 1. When the direction in which the fixed pile insertion tube 3 is provided is the front surface of the column main body 2, the mounting hook 13 is constituted by a vertically long rod-like body or ring-like body that protrudes on both sides of the column main body 2. Here, by fixing the curved portion of the rod-like body bent in a substantially U shape by welding or the like from the back side of the column main body 2, the straight portion protrudes on both sides of the column main body 2 to form the column main body 2. The mounting hook 13 is provided in parallel with the mounting hook 13. As shown in the conventional example of FIG. 6, the attachment hook 13 may not be provided. In this case, the fastening band 12 is directly wound around the column main body 2.
