A pair of upper and lower brackets (6) and (6) are integrally formed on the outer surface in the panel width direction of the one vertical frame (4) of the panel body (1) having the above-mentioned structure with a vertical gap. It is projected. These brackets (6) (6) are in the shape of a rectangular block when viewed from the front, and have connection holes (7) penetrating from the upper surface to the lower surface. Also, as shown in FIG.
A slit (8) is also formed penetrating from the upper surface to the lower surface so as to penetrate from the inner circumference of the connecting hole (7) to the side surface opposite to the panel body (1). Furthermore, the slit
A stepwise cutout (11) is formed from the upper end of the bracket (6) to the middle of the upper and lower sides of the bracket (6) with a surface passing through the center of the connection hole (8) and the connection hole (7) as a boundary. The slit (8) is exposed in a half-divided manner from the upper end over a certain length.

The vertical frame (4) on the opposite side of the same panel body (1) corresponds to the positions of the brackets (6) and (6) on the outer surface of the panel (p) in the width direction. A pair of upper and lower vertical shafts 9 and 9 are provided. These vertical axes (9)
(9) has a diameter slightly smaller than that of the connecting hole (7), and upper and lower ends thereof are vertical plate-shaped supporting pieces (10) and (10) protruding from the outer surface of the vertical frame (4), respectively. It is connected to the vertical frame (4) through. The support piece (10) has a thickness smaller than the width of the slit (8), and the width thereof is longer than the left and right widths of the slit (8).

A vertical support pipe (12) is fixed to the lower ends of the left and right vertical frames (4) of the panel body (1). (13)
Is a flat plate-shaped installation plate, and as shown in FIG. 2, a pair of vertical pieces (14) and (14) facing each other are erected on the upper surface of the installation plate (13). Bolt pin (15) and wing nut inserted between pieces (14) (14)
Depending on (27), the supporting leg (1) which consists of a round bar (a pipe is also acceptable) (1
The lower end of 6) is attached rotatably in the vertical direction. At that time, the hole of the support leg (16) through which the bolt pin (15) is inserted.
(31) is a long hole that is long in the vertical direction, and as shown in Fig. 3,
When the supporting leg (16) is moved downward within the range of the elongated hole (31), the lower end of the supporting leg (16) is a supporting hole formed in the installation plate (13).
By being inserted into the (32), the supporting leg (16) is supported in a state substantially vertical to the installation plate (13) so as not to fall.

The supporting leg (16) is the support pipe.
It is inserted into the hole of (12), and the height of the panel body (1) is adjusted by sliding the support leg (16) up and down in this hole, and as shown in FIG. (12) It is supposed that the supporting leg (16) is pressed by the tip of the push bolt (17) screwed into the screw hole on the side surface and fixed at the height position. In addition, the supporting leg (16) is thus 1 per panel (p).
Only the individual pieces are held vertically by connecting the panels (p) to each other. Note that FIG.
The mounting plate (13) has fixing holes (28), as shown in.
Is formed, and the anchor (29) is driven into the ground through the fixing hole (28) and fixed to the ground.

FIG. 5 is a view of the panel (p) seen from the back side, and (18) is a rod-shaped cane, the lower end of which is the support leg.
It is rotatably mounted on a bolt pin (15) of a mounting plate (13) having the same structure as mounted on (16). On the other hand,
As shown in FIGS. 6 and 7, a pair of left and right L-shaped protrusions (19) and (19) are provided on the back surface of the left and right vertical frames (4) in a back-to-back relationship with each other along the vertical direction. As a result, rail grooves (20) (20) are formed on the left and right side surfaces of the vertical frame (4). (21) is a slider formed in a U shape when viewed from the top, and the inward lip pieces (21) and (21) integrally formed at both ends in the U shape are respectively attached to the rail groove. (2
It is inserted in the 0) (20) and slid up and down along the rail grooves (20) (20).

Further, a bolt pin (23) inserted between a pair of support pieces (22) (22) protruding from the surface of the slider (21).
The upper end of the cane (18) is rotatably attached. Then, the tips of the push bolts (24) screwed into the same slider (21) from the outside are brought into contact with the vertical frame (4) and further screwed, so that the lip pieces (21) (21) are attached to the rail groove (20). It will be pressed against (20) and will be fixed in that position.
Therefore, for example, when there is no extra space on the back side of the panel body (1), loosen the push bolt (24) to remove the slider.
The cane (18) can be fixed by sliding (21) upward.
If the lower end of the cane (18) can be installed by pulling it toward the panel body (1) side, or if there is sufficient space and the lower end of the cane (18) is to be installed separately, the slider (21) is slid downward.

Reference numeral (25) is a curtain plate provided with elongated holes (26) (26) elongated in the vertical direction at both left and right ends, and bolts (30) (30) inserted into these elongated holes (26) (26). ) Is screwed to the back of the vertical frame (4) and fixed, and after the panel (p) is installed, slide it downward within the long hole (26) to lower the ground below the panel (p). It is possible to close the gap between.

A method of connecting the panels (p) for the guard fence having the above structure will be described. First, as shown in FIG. 8, the bracket (6) of one panel (p) and the other of the panels (p) to be connected to each other are connected. With the vertical axis (9) of the panel (p) facing each other, lift up the panel (p) on the vertical axis (9) side, and at the same time insert the lower end of the vertical axis (9) into the connecting hole (7) from above. While inserting the lower vertical support pieces (10) into the slits (8), the bracket (6) moves the upper and lower vertical support pieces (10) (1).
It is only necessary to lower it to the position shown in FIG.

At this time, the lower end of the vertical axis (9) on the upper side is
Once placed on the notch (11), the vertical shaft (9) is aligned with the connecting hole (7) exposed in half, and the vertical support piece (10) is slit ( When contacting the exposed part of 8), the lower vertical shaft (9) and the vertical support piece (10) also
Since it is automatically positioned with respect to the corresponding connecting hole (7) and slit (8), it is sufficient to lower it as it is, and the connecting work can be performed very easily. The half of the connecting hole (7) is not an exact half and may be smaller than that. Further, the slit (8) may be formed on the front side or the back side of the bracket (6).

The vertical shaft (9) in the state of being connected as described above.
Can rotate within the connecting hole (7), so as shown in FIG. 10, by horizontally rotating the panel (p) about its vertical axis (9) as a fulcrum, the panel (p) ( p) can be installed by bending each other in the range of about 180 degrees. At this time, since the gap between the slits (8) is smaller than the diameter of the connecting hole (7), there is no risk that the vertical shaft (9) will come off in the horizontal direction. Also, the bracket (6) has a push bolt from the front side.
(27) is screwed in, and by pushing the tip of this push bolt (22) against the vertical shaft (9) and screwing it in, the vertical shaft
(9) can be pressed against the inner wall of the connecting hole (7) and fixed so as not to rotate and move vertically.

FIG. 11 and FIG. 12 show the case of installation on a sloping ground. When the bracket (6) is located at the upper and lower center of the vertical axis (9), the length of the vertical axis (9) is set so as to allow a considerable margin between the bracket and the upper and lower support pieces (10). Has been done. Therefore, the bracket (6) changes its height with respect to the vertical axis (9) by sliding in the range between the upper and lower vertical support pieces (10), (10) with respect to the vertical axis (9). It is possible,
Accordingly, the panels (p) and (p) can be installed with a step difference therebetween. FIG. 11 shows the case where the vertical axis (9) side is low, and the bracket (6) has moved upward to the lower end position of the upper support piece (10). FIG. 12 shows the case where the bracket (6) side is low, and the bracket (6) has moved to the upper end position of the lower support piece (10).

In each case, the supporting leg (16) is shown in FIG.
As shown in 3, loosen the wing nut (27) of the bolt pin (15) and pull up the support leg (16) within the range of the elongated hole (31) to raise it from the support hole (32) of the installation plate (13). Pull out and rotate the mounting plate (13) so that it tilts along the inclined surface around the bolt pin (15) and the push bolt (1
Loosen (7) and adjust the length of the support leg (16) so that the installation plate (13) is in contact with the ground.

The panel body (1) can be molded from a resin material, which makes it lightweight and easy to handle. Further, the wall plate (6) can also be made lighter by using a resin material in the same manner.

[0023]

As described above, according to the present invention, since it is only necessary to insert the vertical shaft into the connecting hole while inserting the supporting piece into the slit, it is possible to easily connect the panels to each other. There is an effect that the connection work can be performed in a short time.

Further, since the bracket having the connecting hole and the slit is provided at one end of the panel and the vertical shaft supported through the supporting piece is provided at the other end, the structure is simple and the manufacturing can be performed at a low cost.

Further, since the height of the bracket can be changed with respect to the vertical axis in the range between the opposing ends of the upper and lower support pieces, the panels can be stepped and connected to each other in this range. It can be easily applied to slopes and steps.

In addition, by forming a notch in the bracket,
Since the connecting holes and slits are exposed in half from the upper end to a certain length, when inserting the vertical shaft and the vertical support pieces into them, you do not have to aim them from above, but just abut from the side. Since they can be positioned, the connecting work can be performed more easily. In particular, when two brackets and two vertical shafts are provided on the upper and lower sides, it is necessary to perform positioning on both the upper and lower sides at the same time, and this positioning is very difficult. It can be resolved.
