Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a grid panel mounting bracket, and more particularly to a grid panel mounting bracket that allows a grid panel to be easily mounted on a column.
[0002]
[Prior art]
Conventionally, in order to attach a grid panel composed of horizontal wires and vertical wires assembled in a grid shape to a square column, bolt holes are formed in the front and rear walls of the square column, and the bolts inserted into the bolt holes are used to form a grid. This is done by fixing the panel mounting bracket, or by previously installing a blind nut on the front wall of the square column and fixing the lattice panel mounting bracket with bolts screwed into the blind nut.
[0003]
[Problems to be solved by the invention]
However, in each of the above-described conventional techniques, the grid panel mounting bracket and the bolt for fixing the same to the column are separate, so the grid panel mounting bracket can be mounted to the column with one hand. Since it was necessary to hold the metal fittings, insert the bolts with the other hand, and tighten them, it took time and effort to install the lattice panel.
[0004]
Accordingly, an object of the present invention is to provide a lattice panel mounting bracket that can easily attach a lattice panel to a column.
[0005]
[Means for Solving the Problems]
According to the first aspect of the present invention, in the metal fitting for attaching the lattice panel made of the horizontal wire and the vertical wire assembled in a lattice shape to the support having the attachment hole formed in the side wall, the through hole is formed in the lower part. A web that is in close contact with the side wall of the column, a flange that is formed at the upper end with a notch into which the horizontal wire is fitted, and a web for fixing the horizontal wire that is fitted into the notch of the flange. A U-shaped member formed of a pressing piece having a bolt hole formed by bending a lower portion between the flanges, and a beak-shaped expansion piece having a protrusion formed on the outer surface, which is inserted into the mounting hole of the support column; And a nut formed at the base of the beak-shaped extension piece, which is larger than the bolt hole of the pressing piece and can be inserted into the through-hole of the web. And the beak inserted into the nut of the connecting member inserted into the through hole of the web from the bolt hole of the pressing piece, and thus inserted into the mounting hole of the support column. It is characterized in that it comprises a bolt for expanding the shape expansion piece and engaging the protrusion with the back surface of the mounting hole.

DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the lattice panel mounting bracket of the present invention will be described with reference to the drawings.
[0007]
FIG. 1 is a perspective view showing a state in which a lattice panel is attached to a square column by the lattice panel attachment fitting of the present invention, FIG. 2 is a front view showing a U-shaped member in the lattice panel attachment fitting of the present invention, and FIG. FIG. 4 is a side view showing a U-shaped member in the lattice panel mounting bracket of the present invention, and FIG. 5 is a U-shaped shape in the lattice panel mounting bracket of the present invention. FIG. 6 is a rear view showing a U-shaped member in the grid panel mounting bracket of the present invention, FIG. 7 is an assembled side view of the grid panel mounting bracket of the present invention, and FIG. 8 is a grid of the present invention. It is a top view which shows the expansion state of the beak-shaped expansion piece of the coupling member in a panel mounting bracket.
[0008]
1 to 8, reference numeral 1 denotes a square column in which a mounting hole 1 </ b> A (see FIG. 8) is formed on one side wall, and 2 denotes a grid attached to the square column 1 by the grid panel mounting bracket A of the present invention. It is a panel, and is composed of a horizontal wire 2A and a vertical wire 2B assembled in a grid pattern. Note that the column 1 to which the lattice panel 2 is attached may be a circular column or the like.
[0009]
3 is a U-shaped member having a through-hole 4A formed in the lower part thereof, a web 4 closely contacting the side wall of the square support 1, a flange 5 in which a cut 5A into which the horizontal wire 2A is fitted is formed at the upper end, and a flange 5 and a pressing piece 6 for fixing the horizontal wire 2A fitted in the notch 5A. The upper width of the cut 5A is formed to be narrower than the lower width, thereby making it difficult for the horizontal wire 2A of the lattice panel 2 to come out of the cut 5A. The pressing piece 6 is formed by bending the lower part of the web 4 between the flanges 5, and has a long hole bolt hole 6 </ b> A into which a bolt described later is inserted. The pressing piece 6 opens in a direction away from the web 4 in a state before the bolt is tightened by a spring action. The upper part of the pressing piece 6 is curved in an arc shape so that the horizontal wire 2A can be easily fixed.
[0010]
Reference numeral 7 denotes a coupling member for fixing the U-shaped member 3 to the side wall of the square column 1, and a beak-shaped expansion piece 8 having a projection 8 </ b> A formed on the outer surface thereof, which is inserted into the mounting hole 1 </ b> A of the square column 1. The nut 9 is formed in the base portion of the beak-shaped extension piece 8 and can be inserted into the through hole 4A of the web 4 of the U-shaped member 3. The nut 9 is formed larger than the width of the bolt hole 6 </ b> A of the pressing piece 6. Therefore, when the bolt is inserted from the bolt hole 6 </ b> A of the pressing piece 6 and screwed into the nut 9, the coupling member 7 cannot be detached from the U-shaped member 3.
[0011]
Reference numeral 10 denotes a bolt for expanding the beak-shaped expansion piece 8. The bolt 10 is screwed into the nut 9 inserted into the through hole 4A of the web 4 from the bolt hole 6A of the pressing piece 6, and thus the beak-shaped extension piece 8 inserted into the mounting hole 1A of the square column 1. And the protrusion 8A is engaged with the back surface of the mounting hole 1A. That is, the protrusion 8A is brought into contact with the back surface of the side wall of the square column 1 to fix the U-shaped member 3 to the side wall of the square column 1.
[0012]
According to the lattice panel mounting bracket of the present invention configured as described above, the lattice panel 2 is attached to the square column 1 as follows.
The nut 9 of the coupling member 7 is inserted into the through hole 4A of the U-shaped member 3 with the beak-shaped extension piece 8 protruding from the web 4, and the bolt 10 is inserted into the nut 9 from the bolt hole 6A of the pressing piece 6 in advance. Screw it in. Thereby, the U-shaped member 3, the coupling member 7 and the bolt 10 are integrated without being detached from each other. Next, the beak-shaped extension piece 8 is inserted into the mounting hole 1 </ b> A of the square column 1. Since the protrusion 8 </ b> A is formed on the beak-shaped extension piece 8, the U-shaped member 3 is unlikely to drop from the mounting hole 1 </ b> A of the square column 1.
[0013]
Next, the horizontal wire 2 </ b> A of the lattice panel 2 is put into the notch 5 </ b> A of the U-shaped member 3 while holding the U-shaped member 3. Then, the bolt 10 is tightened. As a result, the pressing piece 6 of the U-shaped member 3 is closed and the horizontal wire 2 </ b> A is fixed to the U-shaped member 3. At the same time, the beak-shaped extension piece 8 is pushed and spread on both sides, whereby the projection 8A engages with the back surface of the mounting hole 1A of the square column 1 and the coupling member 7 is pulled forward. Are firmly fixed to the square column 1 together with the lattice panel 2.
[0014]
【The invention's effect】
As described above, according to the present invention, the U-shaped member, the coupling member, and the bolt are integrated so as not to be separated from each other, thereby providing a useful effect that the lattice panel can be easily fixed to the column. It is.
