Description

  The present invention relates to a fence structure that is mainly used outdoors, such as a roadside or a site boundary, and is preferably used particularly for an inclined installation surface, and a fence body that constitutes the fence structure.

  Conventionally, as this kind of fence structure, it is provided with a support and a fence attached to the support via a joint, and the fence is arranged so that the axis direction intersects the horizontal beam and the axial direction of the horizontal beam. A vertical beam connected to the horizontal beam, and the vertical beam and the horizontal beam are connected so as to be relatively rotatable so that the crossing angle in the axial direction of both of them changes. A gap portion with a downward opening is formed at the end in the axial direction, and a joint for connecting the support column and the fence body includes a fixed portion fixed to the support column, and the axial direction of the horizontal rail from the fixed portion.

  However, in the above-described conventional fence structure, the fixture is inserted along a direction orthogonal to the axial direction of the horizontal beam and the width direction of the connection portion to connect and fix the connection portion and the horizontal beam. Therefore, for example, a load applied to the fence body due to snow accumulation or the like acts on the fixture as a shearing force. That is, the conventional fence structure has a structure that supports the load applied to the fence body by the shearing force of bolts and pins as a fixture, and therefore there is room for improvement in terms of strength.

The horizontal beam is provided with a groove part into which the axial end of each end vertical beam can be inserted at both ends in the axial direction, and at least one end of the both ends in the axial direction. Each of the end vertical bars is inserted into the groove portion in the horizontal direction. The at least one end vertical beam is connected to a horizontal beam by an attachment member inserted through the hole and the positioning hole, and the positioning of the mounting member is determined. The rail body is configured to be movable relative to the horizontal beam along the axial direction of the horizontal beam by movement with respect to the hole, and the fence body is connected to the support column through the connecting portion. By being done, it is attached to this support | pillar, and the said connection part protrudes from the side surface of each said end vertical beam, The fence protrusion part integrally formed in this each end vertical beam, and the said support | pillar It is provided with a column projection protruding from a side surface and formed integrally with the column, and the fence projection is mounted on the column projection.

  In the fence structure of the configuration, the vertical beam and the horizontal beam that constitute the fence body are connected so as to be relatively rotatable so that the crossing angle in the axial direction of both changes. The shape of the fence can be changed by relatively rotating the vertical beam or the horizontal beam. Therefore, the fence structure can be installed by changing the shape of the fence body according to the inclination of the inclined installation surface.

  Moreover, the fence protrusion part and the column protrusion part which constitute the connecting part for connecting the vertical beam and the column of the fence body are respectively projected integrally with the vertical beam and the column, and the fence projection part is Since the vertical rail and the column of the fence body are connected to each other by being placed on the column projecting portion, the load applied to the fence body due to, for example, snow can be supported by the fence projecting portion and the column projecting portion.

  A pair of the horizontal rails 6 are provided so that the axis C3 is parallel to each other, and the groove portions 62 are arranged to face each other.

  One end of each of the vertical bars 7 and 8 is connected to one horizontal bar 6, and the other end is connected to the other horizontal bar 6. A plurality of the vertical bars 7 and 8 are arranged along the direction of the axis C <b> 3 of the horizontal bar 6. The plurality of vertical bars include an end vertical bar 7 positioned at both ends of the horizontal bar 6 in the direction of the axis C <b> 3, and an intermediate vertical bar 8 disposed between the vertical bars 7 at both ends.

  As shown in FIGS. 4 (A) and 4 (B), the end vertical rail 7 is crushed so that both ends of a tube body having a straight circular cross section having a straight line C4 are substantially flat, thereby forming a flat portion 71. The flat portion 71 is formed with a rotation hole 72. In addition, the front-end | tip part 711 of the flat part 71 is formed in circular shape. The end vertical bar 7 is manufactured from a metal pipe such as a steel pipe or an aluminum alloy pipe, and is appropriately subjected to a surface treatment such as painting or plating. In addition, a tubular body having a circular cross section is preferably used as the end vertical rail 7, but a tubular body having a rectangular cross section or an elliptical shape may be used.

  Further, the end vertical rail 7 is formed with a fence protrusion 9 that protrudes radially outward from the side surface of the end vertical rail 7. The fence protruding portion 9 includes a cylindrical portion 91 whose axis C5 direction extends along the axis C4 direction of the end vertical rail 7 and a mounting portion 92 that extends radially outward of the cylindrical portion 91. In this embodiment, the cylinder part 91 is a rectangular tube shape, and the internal hole becomes the fence side connection hole 911 which is a long hole long in the said protrusion direction (namely, radial direction of the end vertical bar 7). In addition, one end surface of the cylindrical portion 91 is a fence-side mounting surface 912 that is perpendicular to the axis C4 of the end vertical rail 7 and is flat. In addition, although the fence protrusion part 9 comprises the connection part 4 which connects the fence body 3 and the support | pillar 2, this point is mentioned later.

  The fence protrusion 9 is formed so as to be integrated with the end vertical rail 7. Specifically, the fence protrusion 9 is integrated with the end vertical beam 7 by welding the attachment portion 92 to the side surface of the end vertical beam 7. In the present embodiment, two fence protrusions 9 are provided at a predetermined interval in the direction of the axis C4 of the end vertical rail 7.

  As shown in FIGS. 5 (A) and 5 (B), a plurality of intermediate vertical bars 8 are provided so that the distance between the axis lines C6 is a predetermined pitch. It is composed. Specifically, the vertical beam unit includes a plurality of intermediate vertical beams 8 and a pitch securing member 10 that connects the intermediate vertical beams 8 with a predetermined pitch.

  The intermediate vertical beam 8 is crushed so that both ends of a tube body having a straight circular cross section with an axis C6 being substantially flat are formed into a flat portion 81, and a distal end portion 811 of the flat portion 81 has a circular shape. Is formed. The intermediate vertical beam 8 is manufactured from a metal pipe such as a steel pipe or an aluminum alloy pipe, and is appropriately subjected to a surface treatment such as painting or plating. In addition, a tubular body having a circular cross section is preferably used as the intermediate vertical beam 8. However, a tubular body having a rectangular cross section or an elliptical shape may be used. Further, the outer diameter of the intermediate vertical beam 8 is smaller than the outer diameter of the end vertical beam 7.

  The pitch securing member 10 is a long plate-like body having an L-shaped cross section in which one piece is an attachment piece 101 and the other piece is a positioning piece 102, and is a metal plate such as a long steel plate. The pitch securing member 10 has mounting holes 1011 formed at both ends in the longitudinal direction of the mounting piece 101. The mounting hole 1011 is a long hole that is long in the longitudinal direction of the pitch securing member 10. Note that a pair of pitch securing members 10 are provided so that their longitudinal directions are parallel to each other.

  A plurality of intermediate vertical bars 8 are pivotally attached to the pitch securing member 10 so as to be rotatable at a predetermined pitch, thereby constituting a vertical beam unit. Specifically, each mounting piece 101 of the pair of pitch securing members 10 and the flat portion 81 of the intermediate vertical beam 8 are overlapped, and the mounting piece 101 and the flat portion 81 are pressed and deformed in an uneven shape and caulked. Thus, the vertical beam unit is configured. Therefore, the pitch between the intermediate vertical bars 8 is a fixed pitch. The pitch securing member 10 and the intermediate vertical beam 8 are relatively rotatable with a caulked portion as a caulking shaft 82. That is, the pitch securing material 10 and the intermediate vertical beam 8 are connected so that the longitudinal direction of the pitch securing material 10 and the axis C6 direction of the intermediate vertical beam 8 intersect, and the intersection angle changes. Are pivotably connected to each other.

  The fence body 3 is configured by attaching the end vertical beam 7 and the vertical beam unit to the horizontal beam 6 as described above. Specifically, as shown in FIGS. 6A and 6B, the pitch securing member 10 is accommodated inside the horizontal beam 6 so that the flat portion 81 of the intermediate vertical beam 8 fits into the groove 62 of the horizontal beam 6. The flat portion 71 of the end vertical beam 7 is fitted into the groove 62 of the horizontal beam 6, and the mounting member 11 such as a bolt is attached to the positioning hole 61 of the horizontal beam 6, the rotation hole 72 of the end vertical beam 7, and the pitch securing material. The fence body 3 is configured by being inserted into the 10 mounting holes 1011 and tightening. The axis C4 of the end vertical beam 7 and the axis C6 of the intermediate vertical beam 8 are parallel to each other. Further, the end vertical bars 7 are not fastened to the pitch securing member 10. Further, the positioning piece 102 of the pitch securing member 10 is in contact with the end portion of the bent piece 63 of the horizontal rail 6.

  Here, since the horizontal beam 6 and the end vertical beam 7 are connected via the mounting member 11, the mounting member 11 serves as an axis, that is, the axis C7 of the mounting member 11 serves as a rotation center. It can be turned. Further, since the pitch securing member 10 and the intermediate vertical beam 8 are relatively rotatable around the caulking shaft 82, the horizontal beam 6 and the intermediate vertical beam 8 are relatively positioned around the caulking shaft 82. It can be turned. Accordingly, the vertical rails 7 and 8 and the horizontal rail 6 are coupled so as to be relatively rotatable so that the crossing angles in the directions of the axes C3, C4, and C6 are changed. The vertical rails 7 and 8 and the horizontal rail 6 are rotatable relative to each other so that the distance between the horizontal rails 6 can be kept large and small while the horizontal rails 6 are kept parallel. In other words, when the fence body 3 moves the pair of horizontal rails 6 in opposite directions in the horizontal direction, the vertical rails (specifically, the intermediate vertical rail 8 and the end vertical rail 7) are inclined with respect to the horizontal rail 6. The shape changes. Moreover, the fence protrusion part 9 is projected from the side surface of the end vertical beam 7 along the axis C3 direction of the horizontal beam 6.

  Further, since the positioning hole 61 is a long hole that is long in the direction of the axis C <b> 3 of the horizontal beam 6, the attachment member 11 can move along the direction of the axis C <b> 3 of the horizontal beam 6. Therefore, each end vertical beam 7 can move relative to the horizontal beam 6 along the direction of the axis C <b> 3 of the horizontal beam 6. In other words, the distance between the two end vertical bars 7 increases or decreases along the direction of the axis C <b> 3 of the horizontal bar 6. On the other hand, since each intermediate vertical beam 8 is connected to the pitch securing member 10 by caulking, its position is fixed. Therefore, the end vertical beam 7 can be brought into contact with and separated from the intermediate vertical beam 8 along the direction of the axis C3 of the horizontal beam 6.

  Such a fence body 3 is attached to the support column 2 by connecting the end vertical beam 7 to the support column 2 via the connecting portion 4. Specifically, as shown in FIG. 6 (A), the fence body 3 includes a fence protrusion 9 projecting from the side surface of the end vertical rail 7 toward the support column 2 from the side surface of the support column 2. 3 is mounted by being mounted on a column projection 5 projecting toward 3. In more detail, the fence protrusion 9 is placed on the column-side mounting surface 512, and, for example, an insertion member 12 such as a bolt is connected to the fence-side connection hole 911 of the fence protrusion 9 and the column-side connection hole of the column protrusion 5. The fence body 3 is attached to the column 2 by being inserted into the column 511 and tightening the fence projection 9 and the column projection 5. In addition, the connection part 4 is comprised with the fence protrusion part 9, the support | pillar protrusion part 5, and the insertion member 12. FIG. Further, the column-side mounting surface 512 of the column protrusion 5 and the fence-side mounting surface 912 of the fence protrusion 9 are in contact with each other. Further, the axis C4 of the end vertical rail 7 and the axis C1 of the support column 2 are parallel to each other. Further, the fence body 3 is rotatable around the axis C <b> 8 of the insertion member 12.

  Here, the distance between the axis C7 of the mounting member 11 which is the center of rotation of the end vertical beam 7 or the horizontal beam 6 and the lower corner 64 (or the upper corner 65) of one end of the horizontal beam 6 in the axis C3 direction. Is smaller than the distance from the axis C7 of the mounting member 11 to the side surface of the support column 2, and larger than the distance between the axis C8 of the insertion member 12 and the axis C4 of the end vertical bar 7. That is, one end surface of the horizontal rail 6 in the direction of the axis C <b> 3 is located between the axis C <b> 8 of the insertion member 12 and the side surface of the column 2.

  The fence structure 1 having the above configuration can be installed on a flat installation surface or an inclined installation surface. That is, when installing on a flat installation surface, as shown in FIG. 1, a plurality of columns 2 are erected so that the axis C1 is in the vertical direction, and the axis C3 of the horizontal beam 6 and the axes of the vertical beams 7 and 8 are arranged. The shape of the fence body 3 is deformed so that C4 and C6 are orthogonal to each other, and the fence body 3 is attached between the columns 2.

  On the other hand, when installing on an inclined installation surface, as shown in FIG. 7, a plurality of columns 2 are erected so that the axis C1 is in the vertical direction, and the axis C3 of the horizontal rail 6 is along the inclination of the installation surface. The shape of the fence body 3 is deformed so that the axis lines C4 and C6 of the vertical bars 7 and 8 are parallel to the axis line C1 of the support column 2 (that is, in the vertical direction), and the fence body 3 is attached between the support columns 2.

  In the fence structure 1 having the above-described configuration, the crossing angles of the longitudinal beams 7 and 8 and the horizontal beam 6 constituting the fence body 3 in the directions of the axes C3, C4, and C6 are changed. Since they are connected so as to be relatively rotatable, it is possible to change the shape of the fence body 3 by relatively rotating the vertical rails 7 and 8 or the horizontal rails 6. Specifically, the shape of the fence body 3 is changed by moving the pair of horizontal rails 6 in the horizontal direction opposite to each other so that the intermediate vertical beam 8 and the end vertical beam 7 are inclined with respect to the horizontal beam 6. Can do. Therefore, the axis C3 of the horizontal beam 6 is aligned with the inclination of the installation surface, and the axes C4 and C6 of the intermediate vertical beam 8 and the end vertical beam 7 are aligned with the axis C1 of the column 2, so that the shape of the fence body 3 is obtained. It is possible to deform and install the fence structure 1 along the inclination of the installation surface.

  Moreover, the fence protrusion part 9 and the pillar protrusion part 5 which comprise the connection part 4 for attaching the fence body 3 to the support | pillar 2 are each integrated with the end vertical beam 7 and the support | pillar 2, and this fence protrusion part 9 is integrated. Since the fence body 3 and the pillar 2 are connected to each other with the pillar protrusion 5 placed on the pillar protrusion 5, the fence protrusion 9 and the pillar protrusion 5 support the load applied to the fence body 3 due to, for example, snow. And sufficient strength can be obtained.

  Moreover, when attaching the fence body 3 to the support | pillar 2, since the fence protrusion part 9 is mounted in the support | pillar protrusion part 5, that is, the fence body 3 can be temporarily placed on the support | pillar 2, construction becomes easy.

  Further, among the plurality of vertical bars 7, 8, the respective end vertical bars 7 positioned at both ends in the direction of the axis C 3 of the horizontal bar 6 move relative to the horizontal bar 6 along the direction of the axis C 3 of the horizontal bar 6. It is possible, that is, the distance between the two end vertical bars 7 can be increased or decreased along the direction of the axis C3 of the horizontal bar 6, so that the fence protrusion provided on one end vertical bar 7 is The distance between the portion 9 and the fence protrusion 9 provided on the other end vertical beam 7 can be increased or decreased along the direction of the axis C3 of the horizontal beam 6. Therefore, according to the distance between the column projection 5 of one column 2 and the column projection 5 of the other column 2, the rail projection 9 provided on one end vertical beam 7 and the other end The distance between the rail projections 9 provided on the crosspiece 7 can be changed, and the adjustment of the mounting pitch becomes easy.

However, since the distance from the axis C7 of the mounting member 11 to the side surface of the support column 2 is smaller, the shape of the fence body 3 is adjusted so as to match the inclination even when the inclination angle of the installation surface is large. Can be deformed.

  Moreover, since the cross-sectional shape of the pitch securing member 10 is L-shaped, rigidity can be maintained even if a large number of intermediate vertical bars 8 are provided. Further, the pitch securing member 10 having a substantially L-shaped cross section is accommodated inside the horizontal beam 6 in a state where the positioning piece 102 is in contact with the end of the bent piece 63 of the horizontal beam 6.
