Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grid fence, and more particularly to a support column fixing device for a grid fence with a rim.

[Prior art] As this kind of column fixing device, for example,
No. 6523 is known.

According to this proposal, a cylindrical rim of the grid fence formed by curving the end of the fence into a cylindrical shape, a fitting cylindrical body that fits into the cylindrical rim, and a pillar attached to the fitting cylindrical body protruding from the support side. It is arranged on the outside between a connecting member consisting of a piece and a pair of parallel cross members, and is fastened with bolts and nuts in a face shape to the fitting cylinder, and can be freely fixed to the body rim in the shape of a pressure on the body rim. The above-mentioned pillar fixing device is provided with a pair of abutment plates having the same structure as the above-mentioned ones, and bolts and nuts for fastening and fixing the pillar attachment piece to the pillar.

[Problems to be solved by the invention] However, in this case, since a connecting member and a pair of backing plates are used, the number of parts is large, and since the connecting member is equipped with a support support piece, it is difficult to attach the fitting cylinder to the body rim. Until it is inserted and fixed, this connecting member itself rotates and tends to fall over, so it is necessary to hold it down by hand, locate the tightening position of the body rim, and then attach a pair of abutments. It is necessary to fasten with plates and bolts/nuts. For this reason, the work of fixing the grid fence to the rim of the grid fence using this column fixing device is complicated, and together with the large number of parts mentioned above, the workability of this column fixing device cannot necessarily be said to be good.

The present invention was developed in view of the above circumstances, and the problem to be solved is to reduce the number of parts as much as possible, and to improve workability so that the grid fence can be fixed to the support simply and reliably. To provide a support post fixing device for a grid fence with a rim.

[Means for Solving the Problems] In order to solve this problem, the present invention uses a split cylinder as the fitting cylinder of the connecting member, and provides a pair of upper and lower end split slits in this, and the end split slits are provided with holes in the body rim. By fitting the fitting cylindrical body into the body rim so as to receive the ends of the vertical members, the connecting member is held in a manner to prevent it from falling over, and the single connecting member fitting cylindrical body can be attached to bolts and nuts without using a backing plate or the like. In other words, the present invention includes a configuration in which the longitudinal members are extended and the end portions of the longitudinal members are fixed. A grid fence is formed into a split tube shape having a rim of the grid fence which is vertically penetrated at the center position in the depth direction, and a pair of upper and lower split slits that fit into the rim and receive the end portions of the vertical members, and are bolted to the fence by bolts and nuts. A connecting member consisting of a fitting cylinder which is fastened in a compressed manner with a split slit at an intermediate position between the ends of the vertical members and can be freely fixed to the above-mentioned trunk edge, and a column attachment piece protruding from the column side of the fitting cylinder; This invention relates to a pillar fixing device for a grid fence with a rim, characterized in that it is equipped with bolts and nuts for tightening and fixing a pillar attachment piece to the pillar, and this is a means for solving the above-mentioned problems as a gist of the invention.

[Example] The present invention will be explained in more detail with reference to the drawings showing the example below. 1 is a grid fence made of a combination of steel round bars with a diameter of 5 mm, and 3 and 4 are its vertical members and 4, respectively. A horizontal member, 5 is a cylindrical body edge disposed at the upper and lower ends thereof, 10 is a connecting member, 19
indicates a cylindrical support.

In this example, the rim 5 is separate from the grid fence and has the same length as a ring material 6, a pair of front and rear end cross members 7 that define an end opening groove 9, and a number of intermediate cross members 8. The furring 5 is welded and fixed to the upper and lower ends of the grid fence 1, respectively.

That is, this welding and fixing is performed by fitting the furring 5 to the upper and lower ends of the grid fence 1 through the end opening groove 9, and attaching each vertical bar 3 to the end cross member 7 and the uppermost part of the grid fence 1 facing each other at the tip. This is done by welding to the intermediate cross member 8 of the grid fence 1, so that the furrow 5 of the grid fence 1 is formed by vertically extending the vertical members 3 and vertically aligning the ends of the vertical members 3 to the central position in the depth direction. It is assumed that it is provided in a penetrating manner.

In this example, the connecting member 10 is made by bending a steel plate and integrally includes a fitting cylinder 11 and a support support piece 14. It has a pair of upper and lower split slits 12 with a width of 6 mm, for example, and long holes 13 on the front and rear walls, and has a split cylinder shape with an upwardly curved cross section, and is inserted into the inner wall and receives the ends of the vertical members 3. The column attachment piece 14 is a vertical curved plate-like piece that is provided with an elongated bolt hole 15 in the width direction of the column 19 and protrudes from one side of the column 19 of the fitting cylinder 11.

The connection member 10 is generally fixed to the support column 19 of the grid fence 1 by first fixing the insertion tube portion 11 of the connection member 10 to the grid fence 1 in advance, and then further fixing the support support piece 14 to the support column 19.

That is, the fitting cylinder part 11 of the connecting member 10 is fixed to the grid fence 1 by fitting the fitting cylinder part 11 into the furring rim 5 and inserting the fitting cylinder part 11 into the pair of upper and lower split slits 12 on the longitudinal end side of the furring 5. By receiving the ends of the plurality of vertical members 3 located therein, the connecting member 10 is held on the flange 5 in a manner that prevents it from falling over, and the fitting cylindrical portion 1
1 through the elongated hole 13 and screwing the nut 18, the split slit 12 is compressed using the bolt nut at an intermediate position between the ends of the vertical members 3 of the rim 5. It is said that this is done by tightening it in a shape. That is, due to this tightening, the split slits 12 clamp the ends of the plurality of longitudinal members 3 located at the longitudinal ends of the furring 5, and the clamping due to this tightening causes the fitting members to 1
0 is fixed to the furring 5 in a fitted state.

Also, a connecting member 1 fixed to the grid fence 1
The post attachment piece 14 is attached to the post 19 in the manner shown in FIG. 10 by attaching the post attachment piece 14 to the post 19 and then inserting a bolt 15 through the bolt hole 15.
The post attachment piece 14 is generally fixed by arranging the connecting members 10 of the adjacent grid fence 1 on the opposing surfaces of the post 19 and fastening them together simultaneously and integrally with a single bolt nut.

At this time, since the bolt holes 15 are elongated in the width direction of the support columns 19, the adjacent grid fences 1 can be installed at different angles with respect to the support columns 19.

In addition, when actually fixing the grid fence 1 to the pillars 19, it is recommended to temporarily fix the fitting cylinder 11 to the flange 5, fix the column attachment piece 14 to the pillar 19, and then permanently fix the fitting cylinder 11. This is convenient, for example, for ensuring the horizontality of the furrow 5.

In the figure, reference numeral 16 denotes an independent column attachment piece that is used for the column 19 located at the end, and 21 indicates an independent column attachment piece that is additionally fixed with bolts 17 and nuts 18 depending on the height dimension of the grid fence 1. This is an auxiliary fixing band.

The illustrated example is as above, but for example,
In order to enable the grid fence to be installed at an angle with respect to the support column, it is also possible to construct the fitting cylinder of the connecting member and the support support piece by connecting separate pieces so that the inclination can be adjusted freely. In carrying out the present invention, including this point, the grid fence, its rim,
The shapes, structures, materials, dimensions, relationships thereof, additions to these, etc. of the connecting members and supports can be variously modified as long as they do not go against the gist of the above-mentioned invention. It's not enough to limit it.

[Effects of the invention] As described above, the present invention provides a rim of a grid fence in which longitudinal members are extended and the end portions of the longitudinal members are vertically penetrated at the central position in the depth direction, and The fitting is made into a split cylinder having a pair of upper and lower split slits that are inserted into and receive the ends of the vertical members, and the split slits are compressed and fastened with a bolt nut at an intermediate position between the ends of the vertical members, so that the fitting can be freely fixed to the above-mentioned rim. The connecting member is characterized by comprising a connecting member consisting of a column attachment piece protruding from the column side of the cylindrical body and the fitting cylinder, and a bolt nut for fastening the column attachment piece to the column. By using the grid fence alone, the grid fence can be fixed to the pillar with as few parts as possible, and the fixing is done by fitting the fitting cylinder into the frame and receiving the end of the vertical member into the split slit. Therefore, it is possible to provide a column fixing device for a grid fence with a rim that has good workability and can easily and reliably fix the grid fence to the column. .

In addition, the fitting cylinder part of the connecting member is fixed by clamping the vertical member in a compressed slit shape by tightening bolts and nuts, while the column attachment piece is also fixed to the column by bolts and nuts. Because of this, it is possible to obtain strong and durable fixing strength.
