  However, although the beam mounting structure described above can handle up to a certain angle in the vertical direction, it must be used separately when installing at an angle in the horizontal direction. In addition, the construction has to be performed while discriminating the metal fitting depending on the mounting location, which is complicated and very troublesome.

  Therefore, the present invention is intended to provide a beam mounting structure for a fence that can handle both the vertical and horizontal angles with a single type of metal fitting.

In order to achieve the above object, the present invention is configured as follows.
In other words, the beam mounting structure for a fence according to the present invention is a beam mounting structure for a fence in which a beam is installed on the front wall of two support columns erected at an interval via a mounting bracket. The beam holding part extends forward from the upper and lower ends of the vertical plate part, except for the column mounting part formed at one end of the vertical plate part, and each of the column mounting part and the beam holding part has one bolt. A mounting hole is drilled, and through the bolt mounting hole, the column mounting portion is mounted to the column by one bolt, and the end of the beam held by the beam holding unit is fixed by one bolt. It is characterized in that it was made to do so.

  According to the present invention, the beam holding part is extended forward from the upper and lower ends of the vertical plate part except for the column mounting part formed at one end of the vertical plate part, and the column mounting part and the beam holding part are provided. Each of which is provided with one bolt mounting hole, and the column mounting portion is mounted on the column with one bolt through the bolt mounting hole, and the end of the beam held by the beam holding unit is mounted on one beam. Since it is fixed with bolts, the mounting bracket can be turned up and down around the bolt inserted in the bolt mounting hole drilled in the column mounting section, so that the fence installation location can be inclined. The beam can be rotated in the horizontal direction around the bolt inserted in the bolt mounting hole drilled in the beam holding section, so that the curvature of the place where the fence is installed can be freely adjusted. Can respond Since one type of mounting bracket can handle the inclination and curvature of the installation location of the fence, the cost of manufacturing and storing many types of mounting brackets can be reduced, and construction must be performed while identifying the mounting bracket according to the mounting location. The above-mentioned troublesome work can be eliminated, and after the fence is temporarily assembled, fine adjustment of the beam angle and mounting bracket angle according to the site's inclination and curvature is carried out efficiently. can do.

  Furthermore, since the beam holding part is extended forward from the upper and lower ends of the vertical plate part, excluding the column attachment part formed at one end of the vertical plate part, when fixing the column attachment part to the column with bolts Since the bolt or nut to be inserted does not interfere with the beam holding portion, it is possible to fix the mounting bracket to the support column after fixing the beam to the beam holding portion, thereby improving the workability.

  Further, in the present invention, at least one of the upper beam holding portion and the lower beam holding portion respectively extending forward from the upper and lower ends of the vertical plate portion has a vertical wall at the end on the column mounting portion side. May be formed. In this way, when the beam is attached to the support via the mounting bracket, the beam end can be pressed against the vertical wall and positioned, so that the beam can be mounted efficiently, Since the end face of the attached beam can be concealed by the vertical wall, the appearance can be improved, which is preferable.

Embodiments of the present invention will be specifically described below with reference to the drawings.
1 is an exploded perspective view showing an embodiment of a beam mounting structure for a fence according to the present invention, FIG. 2 is a perspective view of a mounting bracket shown in FIG. 1, and FIG. 3 is a beam mounting structure for a fence according to the present invention. FIG. 4 is a perspective view of the mounting bracket shown in FIG. 3.

  Reference numeral 1 denotes a support, and a lower portion thereof is buried in the ground and is erected on a plurality of ground surfaces at appropriate intervals. At appropriate positions on the front side and the back side of the support column 1, metal fitting mounting bolt holes 11 are formed at the same level relative to each other. A cap 12 is attached to the top of the column 1 to improve its appearance and prevent rainwater and the like from flowing into the inner surface of the column 1. The support column 1 is made of a metal tube having an appropriate cross-sectional shape such as a circular cross-section, and the surface thereof is subjected to a treatment such as painting or plating.

  Reference numeral 2 denotes a beam, which is installed between the front walls of the plurality of columns 1 via two mounting brackets 3. A beam mounting hole 21 is formed on the side surface of the end portion of the beam 2 at the same level. The beam 2 is also made of a metal tube having an appropriate cross-sectional shape such as a circular cross-section generally used conventionally, and the surface thereof is subjected to treatment such as painting or plating.

  The mounting bracket 3 has a beam holding portion 33 extending forward from the upper and lower ends of the vertical plate portion 31 except for the column mounting portion 32 formed at one end of the vertical plate portion 31. Each of the portions 33 is provided with one bolt mounting hole 34, and the column mounting portion 32 is mounted on the column 1 with one bolt B 1 through the bolt mounting hole 34, and at the beam holding unit 33. The end of the held beam 2 is fixed by one bolt B2. Further, the vertical plate portion 31 is cut off at the end opposite to the column mounting portion 32 so that the end portion of the vertical plate portion 31 does not hit when the beam 2 is rotated to the vertical plate portion 31 side. Yes. Furthermore, there are cases where the beam 1 is attached to the right side and the left side with the support column 1 facing the front, but it is troublesome and costly to separately prepare the right-handed and left-handed mounting brackets. In this embodiment, the mounting bracket 3 is symmetrical with respect to the vertical line so that the left and right can be shared.

3 and FIG. 4, the differences from the embodiment shown in FIG. 1 and FIG. 2 will be described in particular, and the other points are substantially the same as those in FIG.
Reference numeral 35 denotes a vertical wall formed at the end of the upper beam holding portion 33 extending forward from the upper and lower ends of the vertical plate portion 31 of the mounting bracket 3 and the column mounting portion 32 side of the lower beam holding portion 33. The vertical wall 35 suspended from the edge of the upper beam holding portion 33 on the column mounting portion 32 side and the vertical wall 35 erected from the edge of the lower beam holding portion 33 on the column mounting portion 32 side. The wall 35 is formed to face the gap 35 with a gap.

Next, a method for attaching the beam 2 in the left-right direction of the column 1 will be described.
First, with the beam holding portion 33 in the opposite position, the bolt mounting holes 34 drilled in the column mounting portions 32 of the two mounting brackets 3 are aligned, and the bolt mounting holes 34 and 34 and the brackets of the column 1 are aligned. The bolt B1 is inserted into the mounting bolt hole 11, and fastened with the washer W1 and the nut N1. Next, the bolt mounting hole 34 drilled in the beam holding portion 33 and the beam mounting hole 21 drilled in the beam 2 are combined, and the bolt B2 is inserted and fastened to them to attach the beam 2 to the mounting bracket. Fasten to 3 with a washer W2 and a nut N2.

  When the beam 2 is mounted on the mounting bracket 3, the end of the beam 2 can be pressed against the vertical wall 35 formed on the mounting bracket 3 to position the beam 2, so that the beam 2 can be mounted efficiently. Can be implemented.

  Since the mounting bracket 3 can be rotated in the vertical direction around the bolt B1 inserted through the bolt mounting hole 34 drilled in the column mounting portion 32, it can be freely adapted to the inclination of the installation location of the fence. In addition, the beam 2 can be rotated in the horizontal direction around the bolt B2 inserted through the bolt mounting hole 34 formed in the beam holding portion 33, so that the curvature of the place where the fence is installed can be freely adjusted. With one type of mounting bracket 3, it is possible to cope with the inclination and curvature of the installation location of the fence.

  Further, since the beam holding portion 33 is extended forward from the upper and lower ends of the vertical plate portion 31 except for the column mounting portion 32 formed at one end of the vertical plate portion 31, the column mounting portion 32 is attached to the column 1. When the bolt B1 is fixed, the inserted bolt B1 does not interfere with the beam holding portion 33. Unlike the above mounting procedure, after fixing the beam 2 to the beam holding portion 33, the mounting bracket 3 is fixed to the column 1. This also makes it possible to improve the workability.

  Further, after the bolts B1 and B2 are slightly loosened and the fence is temporarily assembled, the bolt B1 is used for fine adjustment of the beam 2 angle and the angle of the mounting bracket 3 in accordance with the inclination and curvature of the installation site. , B2 has nothing to obstruct the tightening operation, so that the fine adjustment operation can be performed efficiently.

  In addition, the bolt attachment hole 34 drilled in the support | pillar attachment part 32 is formed in a rectangular shape, and the square root bolt in which the rectangular protrusion slightly smaller than the bolt attachment hole 34 is formed as the bolt B1 is used. Thus, in the operation of tightening the bolt B1, the washer W1, and the nut N1, it is possible to prevent the bolt B1 and the nut N1 from rotating together by fitting the rectangular protrusion of the bolt B1 into the bolt mounting hole 34.

  Also, as shown in FIG. 3, the end face of the beam 2 can be concealed by the vertical wall 35 formed at the end of the beam holding portion 33 on the column mounting portion 32 side, so that the appearance can be improved. The form of the vertical wall 35 is not limited to the form shown in FIGS. 3 and 4, and the vertical wall 35 is suspended from the end of the upper beam holding part 33 to the vicinity of the lower beam holding part 33. Thus, the vertical wall 35 may not be formed at the end of the lower beam holding portion 33, or vice versa. The point is that the end surface of the beam 2 attached to the mounting bracket 3 may be substantially covered by the vertical wall 35.

  According to the beam mounting structure of the fence according to the present invention, except for the support mounting portion formed on one end of the vertical plate portion, the mounting bracket extends the beam holding portion forward from the upper and lower ends of the vertical plate portion, A single bolt mounting hole is formed in each of the column mounting portion and the beam holding portion, and the column mounting portion is mounted on the column with one bolt through the bolt mounting hole, and the beam held by the beam holding portion. Since the end of each is fixed with a single bolt, the mounting bracket can be rotated in the vertical direction around the bolt inserted into the bolt mounting hole drilled in the column mounting portion. The beam can be freely adjusted according to the inclination of the installation place of the fence, and the beam can be rotated horizontally around the bolt inserted in the bolt mounting hole drilled in the beam holding section. For the curvature of the installation location Since one type of mounting bracket can handle the inclination and curvature of the installation location of the fence, the cost of manufacturing and storing various types of mounting brackets can be reduced, and the mounting bracket can be identified by the mounting location. It is possible to eliminate the troublesome work that must be done while constructing, and after temporarily assembling the fence, the beam angle and the angle of the mounting bracket are adjusted according to the inclination and curvature of the installation site. This can be suitably used as a beam mounting structure for a fence that can efficiently perform the fine adjustment operation.
