Description

  The present invention relates to a column structure and a construction method thereof.

  Conventionally, a temporary fence (a strut structure) including a pedestal, a strut standing on the pedestal, and a fence body (supported member) supported by the strut is known (see, for example, Patent Document 1). . The lower end of the support is inserted and held in an attachment opening formed on the upper surface of the pedestal. In the technique described in Patent Document 1, the size of the mounting opening of the pedestal is such that the lower end of the column is inserted and that the column can be stably supported.

  By the way, the temporary fence is often removed after a certain period of time after installation, and it is desired that the temporary fence can be manufactured at a low cost, can be easily installed, and can be easily removed. Therefore, from the viewpoint of installing a temporary fence at a low cost, an existing base (for example, a guard rail base) may be used to install the temporary fence. For example, in the case of a guard rail, a guard rail column is inserted into the mounting opening of the guard rail pedestal, and concrete is poured into the gap between the mounting opening of the pedestal and the column to fix the column.

  However, if the pedestal is not dedicated to the temporary fence, the mounting opening of the pedestal may be larger than the diameter of the fence column. Therefore, when attaching a support post to the mounting opening of the pedestal, in the state as it is, even if the fence support is inserted, the gap between the mounting opening of the base and the support post of the fence is large, and the support is supported stably. There was something I couldn't do.

  Here, in the structure for supporting the support of the road sign, the mounting opening of the pedestal is formed larger than the diameter of the support, and when the lower end of the support is inserted into the mounting opening of the pedestal, There has been proposed a structure in which a support member is erected on a pedestal with a locking member interposed therebetween (for example, see Patent Document 2).

A larger mounting opening (for example, a mounting opening 21 described later) is disposed between a pedestal (for example, a pedestal 2 described later) formed on the upper surface (for example, a later described upper surface 22) and the support column and the pedestal. A support bracket (for example, a support bracket 5 described later), and a cylindrical portion (for example, described later) having the bottom portion (for example, a bottom plate 53 described later) inserted into the mounting opening while the support column is inserted. And a support bracket having an extending portion (for example, an intermediate plate member 52 described later) that extends in the radial direction from the outer peripheral surface of the cylindrical portion and is disposed on the upper surface of the pedestal, Inserted into the tubular part A first fixing member (for example, a first fixing screw 11 described later) that fixes a column to the cylindrical portion, and a second fixing member (for example, a second fixing described later) that fixes the extending portion to the upper surface of the pedestal. Screw 13), and a post structure (for example, temporary fence 1 described later).

  Moreover, it is preferable to provide an inclination adjusting unit (for example, an inclination adjusting washer 15 described later) capable of adjusting the inclination of the support bracket with respect to the horizontal direction.

  Moreover, it is preferable to further include a spacer member (for example, a spacer sheet 6 described later) disposed between the support column and the cylindrical portion.

  In addition, in the construction method of the support structure, a bracket installation process of installing the support bracket in the mounting opening, a support arrangement process of inserting a lower end portion of the support into the cylindrical part, and the first It is related with the construction method of the support | pillar structure including the fixing process which fixes the said support | pillar to the said cylindrical part with a fixing member.

FIG. 2 is a longitudinal sectional view showing a support structure of the support column 3. FIG. 3 is a plan view showing the support structure of the column 3. FIG. 4 is an exploded perspective view showing the support structure of the column 3.

In the present embodiment, an example in which the support structure is applied to a temporary fence will be described. In the description of the present embodiment, the left-right direction in FIG. 1 is referred to as “left-right direction”.
As shown in FIGS. 1 to 4, the temporary fence 1 includes a plurality of pedestals 2, a plurality of support columns 3, a plurality of fence bodies 4 (supported members), a plurality of support brackets 5, and two spacer sheets. 6 (spacer member), a plurality of first fixing screws 11 (first fixing members), a plurality of second fixing screws 13 (second fixing members), and an inclination adjusting washer 15 (inclination adjusting portion). .

  As shown in FIG. 1, each of the plurality of pedestals 2 is composed of, for example, a concrete block having a predetermined width and extending in a predetermined direction (left-right direction) by a predetermined length. The plurality of pedestals 2 are arranged side by side in a predetermined direction (left-right direction), and adjacent pedestals 2 are connected to each other. The base 2 in the present embodiment is not manufactured exclusively for the temporary fence of the present embodiment, for example, but is an existing guard rail base. Since the temporary fence is often removed after a certain period of time after installation, in this embodiment, for example, an existing guard rail pedestal is used as a pedestal, avoiding embedding the pillars in the ground. . In the case of the guard rail, a guard rail post is inserted into the mounting opening of the guard rail base, and concrete is poured into the gap between the mounting opening of the base and the post to fix the post.

  In addition, in this embodiment, although the example at the time of utilizing the base for existing guardrails as the base 2 is demonstrated, it is not limited to this. The pedestal 2 is not limited to existing ones, and may be newly produced. The pedestal 2 is not limited to a guard rail pedestal, and may have a mounting opening larger than the diameter of the column, and may be, for example, a pedestal that supports a road sign column.

  A mounting opening 21 is formed on the upper surface 22 of the base 2. The attachment opening 21 is formed in a circular shape in plan view, and extends downward from the upper surface 22 of the base 2. In the present embodiment, the attachment opening 21 is formed by a through hole that penetrates the base 2 in the vertical direction. The attachment opening 21 is not limited to a through hole that penetrates the base 2 in the vertical direction. The mounting opening 21 does not have to penetrate the pedestal 2 in the vertical direction. For example, the mounting opening 21 is opened in the upper surface 22 of the pedestal 2 and is recessed downward from the upper surface 22 of the pedestal 2. Alternatively, it may be constituted by a concave groove, or may be constituted by forming an opening in the upper surface plate when the pedestal 2 is hollow. In the mounting opening 21, it is preferable that a vertical space in which a housing cylinder 51 of the support bracket 5 to be described later can be inserted is secured below a portion opened to the upper surface 22 of the base 2.

  The attachment opening 21 is an opening larger than the diameter of the support column 3. In the present embodiment, for example, an existing guard rail base is used as the base 2, and the mounting opening 21 is large enough to insert a guard rail post, and is therefore larger than the diameter of the post 3. . In the present embodiment, the mounting opening 21 is configured to open in a circular shape in plan view, but is not limited thereto, and may be configured to open in a polygonal shape, for example, or an oval You may comprise by opening in a shape.

  As shown in FIG. 1, the plurality of columns 3 are arranged side by side in a predetermined direction (left-right direction) above the plurality of bases 2 arranged side by side in a predetermined direction (left-right direction). Each of the plurality of support columns 3 is formed to extend in the vertical direction. The lower end portion of the column 3 is fixed to the pedestal 2 through the support bracket 5 at the mounting opening 21 of the pedestal 2. Details of the support bracket 5 will be described later.

  A plurality of fence attachment hooks 31 are attached to the column 3 at a plurality of predetermined positions in the vertical direction. The fence body 4 is connected to the column 30 via a plurality of fence attachment hooks 31.

  As shown in FIG. 1, the fence body 4 extends along the column 3. The fence body 4 is configured by arranging a plurality of upper fence bodies 41 and a plurality of lower fence bodies 42 on substantially the same plane. The plurality of upper fence bodies 41 and the plurality of lower fence bodies 42 are formed in a mesh shape.

  The upper fence body 41 and the lower fence body 42 are arranged side by side in the vertical direction, and are connected by a connecting member 401. The plurality of upper fence bodies 41 are arranged in the left-right direction on the upper side of the fence body 4, and the adjacent upper fence bodies 41 are connected to each other by the connecting member 402. The plurality of lower fence bodies 42 are arranged side by side in the left-right direction on the lower side of the fence body 4, and the adjacent lower fence bodies 42 are connected by a connecting member 402. The fence body 4 is supported by the support column 3 via a plurality of fence attachment hooks 31.

The support bracket 5 will be described.
The support bracket 5 is disposed between the support column 3 and the base 2. The support bracket 5 supports the column 3 while being fixed to the base 2. As shown in FIGS. 2 to 4, the support bracket 5 includes a housing cylinder 51 (cylindrical portion) having a bottom plate 53 (bottom portion), an intermediate plate member 52, and a pair of reinforcing support plates 54.

  The accommodating cylinder 51 is formed in a cylindrical shape that extends in the vertical direction. The housing cylinder 51 is also referred to as a sheath tube formed by a tube, for example. The lower end portion of the column 3 is inserted into the housing cylinder 51. The housing cylinder 51 is inserted into the mounting opening 21 of the pedestal 2 with the lower end of the column 3 inserted. The housing cylinder 51 includes an upper cylinder portion 511 disposed on the upper side of the intermediate plate material 52 and a lower cylinder portion 512 disposed on the lower side of the intermediate plate material 52.

  From the viewpoint that the housing cylinder 51 supports the support column 3, the inner diameter of the housing cylinder 51 is preferably the same as the outer shape of the column 3. However, in the present embodiment, the inner diameter of the accommodation cylinder 51 is formed slightly larger than the outer diameter of the support 3 in consideration of ease of insertion of the support 3 into the accommodation cylinder 51. Thereby, a slight gap (for example, 1 mm or less) is provided between the inner peripheral surface of the housing cylinder 51 and the outer peripheral surface of the support column 3. By inserting the support column 3 on which the spacer sheet 6 (described later) is attached to the storage cylinder 51, the gap between the inner peripheral surface of the storage cylinder 51 and the outer peripheral surface of the support column 3 is set in the vertical direction. Spacer sheets 6 are arranged at two spaced locations.

  The intermediate plate member 52 is formed to extend in the radial direction of the housing cylinder 51 from the outer peripheral surface in the middle of the housing cylinder 51 in the vertical direction (axial direction). The intermediate plate material 52 is formed of, for example, a metal plate. In the present embodiment, the intermediate plate member 52 extends in the radial direction from the outer peripheral surface of the storage cylinder 51 above the center in the vertical direction (axial direction) of the storage cylinder 51. The intermediate plate 52 is formed in a rectangular shape whose outer shape is larger than that of the mounting opening 21 of the base 2 in plan view. The intermediate plate 52 is disposed on the upper surface 22 of the base 2 at the periphery of the mounting opening 21 of the base 2. In the present embodiment, the intermediate plate 52 is joined to the outer peripheral surface of the housing cylinder 51 by welding.

  In the present embodiment, when the support bracket 5 is manufactured, for example, the housing cylinder 51 that is a sheath pipe is passed through the intermediate plate material 52 that is a metal plate, and the outer peripheral surface of the housing cylinder 51 (saya pipe). The intermediate plate material 52 (metal plate) is welded to.

  As shown in FIGS. 2 and 4, the pair of reinforcing support plates 54 is formed by a substantially right triangular plate member that connects the lower surface of the intermediate plate 52 and the surface of the housing cylinder 51. The pair of reinforcing support plates 54 supports and reinforces the intermediate plate material 52 from the lower surface side.

  The two spacer sheets 6 are spaced apart from each other in the vertical direction at the portion of the column 3 inserted into the housing cylinder 51. The spacer member 6 has a predetermined width and is attached around the circumferential surface of the support column 3 in the circumferential direction. The spacer sheet 6 is made of an elastic material, for example, hard rubber. The spacer sheet 6 is disposed between the support column 3 and the inner surface of the housing cylinder 51 of the support bracket 5, and holds the column 3 firmly and stably on the housing cylinder 51.

  As shown in FIGS. 2 to 4, the plurality of first fixing screws 11 pass through the peripheral surface of the upper cylinder portion 511 of the housing cylinder 51 through the nut 12, respectively, and The support 3 inserted in the storage cylinder 51 is fixed to the storage cylinder 51 of the support bracket 5 by pressing the tip against the peripheral surface of the support 3 inserted in the storage cylinder 51. In the present embodiment, the three first fixing screws 11 are arranged apart from each other in the circumferential direction of the housing cylinder 51. The three first fixing screws 11 connect the support columns 3 inserted into the housing cylinder 51 to the housing cylinder 51 of the support bracket 5 at three predetermined positions in the circumferential direction of the upper cylinder portion 511 of the housing cylinder 51.

  The plurality of second fixing screws 13 pass through the intermediate plate member 52 and are fastened to the pedestal 2 at positions inside the corners of the intermediate plate member 52 via the washer 14, thereby fastening the intermediate plate member 52 to the pedestal 2. The upper surface 22 is fixed. In the present embodiment, the intermediate plate 52 is fixed to the upper surface 22 of the base 2 at four positions inside the corners of the intermediate plate 52 by the four second fixing screws 13.

  The inclination adjusting washer 15 can adjust the inclination of the support bracket 5 with respect to the horizontal direction. When adjusting the inclination of the support bracket 5 with respect to the horizontal direction, the inclination adjusting washer 15 is, as shown in FIG. 4, the position of the second fixing screw 13 selected in accordance with the direction in which the column 3 is inclined or the degree of inclination. 2, the intermediate plate 52 of the support bracket 5 and the upper surface 22 of the base 2 are disposed. In a state where the intermediate plate 52 is fixed to the upper surface 22 of the pedestal 2 by the second fixing screw 13, the inclination adjusting washer 15 is disposed between the intermediate plate 52 of the support bracket 5 and the upper surface 22 of the pedestal 2 to perform the second fixing. The screw 13 is passed through the tilt adjusting washer 15. Thereby, the inclination of the support bracket 5 with respect to a horizontal direction can be adjusted, and the inclination of the support | pillar 3 can be adjusted.

  Next, the construction method of the temporary fence 1 is demonstrated. FIG. 5 is a method for constructing a temporary fence according to the present embodiment. FIG. 5A is a diagram illustrating a case where the support bracket 5 is attached to the base 2, and FIG. 5B is a diagram illustrating a case where the support 3 is attached to the support bracket 5.
