Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a grating that is laid as a walkway of a factory or a plant, and a stanchion that is installed to partition a construction area. It is about a stanchion to fix to.

[Prior Art] In the corridors of factories or plants, gratings are laid to reduce the weight of structures and prevent slipping. In areas where this grating is laid, access is blocked or construction areas, etc. are sectioned and entry is prohibited. In order to do so, a stanchion as shown in FIG. 8 is installed.

As shown in the figure, the stanchion 1 has a column 2, and a substrate 3 for vertically supporting the column 2 is attached to the lower end of the column 2. In addition, 4 is a pillar 2
It is a hook formed on the.

For example, a plurality of stanchions 1 are installed so as to divide a construction area, and a steel pipe for scaffolding (not shown) is horizontally stretched between the stanchions 1 and a division net is stretched.

Such a stanchion 1 is carried and placed on the marking line, and after the stanchion 1 is placed, it is held in an upright posture by the substrate 3 placed along the upper surface of the grating. Therefore, the stability of the stance of the stanchion 1 depends on the substrate 3.

[Problems to be Solved by the Invention] By the way, the stanchion 1 is merely placed on the grating. Therefore, there is a problem that the stanchion 1 is installed outdoors and easily falls when a cross wind is received.

In order to prevent this, as shown in FIG. 9, when the substrate 5 is formed of concrete material or the like, the stability is increased, but it is not completely fixed to the grating, and therefore may move and fall. Further, since the weight of the stanchion 1 is increased, there is a problem that handling such as carrying is troublesome.

The present invention was created to effectively solve the above problems.

It is an object of the present invention to provide a stanchion that can be fixed to a grating without fail to prevent falling.

[Means for Solving the Problem] In the present invention, in a stanchion installed to partition a construction area into a grating laid as a corridor of a plant, a substrate for standing up the pillar on the grating is installed at the lower end of the hollow pillar. The stanchion body has a locking piece that is inserted into and removed from the pillar and is locked at the lower end by rotation through the grating hole at the lower end, and the extension that extends from the upper end of the pillar. A rod body having a threaded portion at the projecting portion and a threaded portion at the upper end portion of the rod body extending from the upper end portion of the column are screwed together and the locking piece is fastened to the lower surface of the grating, and the locking piece and the board are It is composed of a handle for holding the grating in between.

A peep hole for confirming the orientation of the locking piece may be formed on the substrate.

[Operation] First, in the case of fixing the stanchion to the grating, the locking piece at the lower end of the rod body inserted into the stanchion body is passed through the hole of the grating and half-turned along the lower surface of the grating.

Then, by rotating the handle screwed onto the upper end of the rod, the locking piece is tightened and locked on the lower surface of the grating. That is, the tightening force of the handle causes the grating to be pinched between the base plate and the locking piece of the stanchion body, and the stanchion body is integrally fixed on the grating and held in the standing posture.
It should be noted that this stanchion can also be used as a normal stanchion if the rod is removed from the stanchion body.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

As shown in FIG. 1, a grating 11 forming a corridor is laid in a plant or the like.
A large number of holes 13 having a rectangular cross section, which are partitioned by bars 12 that intersect each other in the vertical and horizontal directions, are formed in the hole.

Further, the grating 11 is provided with a stanchion 21 for partitioning a construction area or the like.

In particular, the stanchion 21 has a stanchion body 22 as shown in FIGS. The stanchion body 22 has a hollow pillar 23 to which a steel pipe for scaffolding (not shown) is horizontally bound (using a clamp).
A division net is stretched.

Further, as shown in FIGS. 2 and 3, a circular substrate 25 is formed at the lower end of the column 23 so as to erect the column 23, and the substrate 25 should be placed along the upper surface of the grating 11. It is enlarged like a flange from the lower end of the column 23. On the upper surface of the substrate 25, three reinforcing ribs 26 that are integrally raised along the pillars 23 are formed at equal intervals in the circumferential direction of the substrate 25 in the illustrated example.

Further, as shown in FIGS. 1 and 2, a rod body is inserted into and removed from the lower end of the hollow portion 27 of the column 23 and is rotatable.
31 is inserted. Therefore, in the center of the substrate 25
An insertion port 28 for inserting 31 will be formed.

As shown in FIGS. 4 and 5, a locking piece 32 extending in a diametrically inverted T-shape is formed at the lower end of the rod body 31, and the locking piece 32 is formed by a grating. 11 holes
It rotates through a predetermined angle through 13 and is locked to the lower surface of grating 11.

That is, as shown in FIG. 6, the locking piece 32 is formed in a rectangular shape smaller than the rectangular hole 13 of the grating 11.
When it is inserted into the hole 13 of the grating 11, it is inserted into the hole 13 of the grating 11 at the rotation position shown by the solid line in the figure, and after insertion, it is rotated 90 degrees as shown by the dashed line in the figure to lock with the bottom surface of the grating 11. To be done.

On the other hand, the rod body 31 is formed to be longer than the stanchion body 22, and a male screw portion 34 is formed at the extending portion of the rod body 31 extending from the upper end portion of the column 23.

As shown in FIGS. 1 and 7, a handle 42 having a female screw portion 41 at the center is screwed into the male screw portion 34. The handle 42 is constructed so as to clamp the locking piece 32 to the lower surface of the grating 11 by its rotation. That is, the tightening force of the handle 42 presses the grating 11 between the base plate 25 of the stanchion body 22 and the locking piece 32.

Further, as shown in FIG. 3, the substrate 25 is formed with a plurality of peep holes 29 for confirming the orientation of the locking pieces 32. These peep holes 29 are formed at positions where the tip 33 of the locking piece 32 is opened when the locking piece 32 is inserted into the grating hole 13 and engages with the lower surface of the grating 11. In this embodiment, three peeping holes 29 are formed between the reinforcing ribs 26, one for each, and each peeping hole 29 has 18 holes.
It is formed in the range of 0 degree at every 90 degrees.

 Next, the operation of the above embodiment will be described.

As shown in Fig. 1, stanchions on the grating 11
In installing 21, the locking piece 32 formed at the lower end of the rod body 31 is passed through the grating hole 13 to form the grating.
Exposed on the underside of 11. When the locking piece 32 is sufficiently exposed, as shown in FIG. 6, the locking piece 32 is moved along the lower surface of the grating 11 to a position where the locking piece 32 intersects the major axis of the grating hole 13 at a substantially right angle. It will be rotated.

Since the substrate 25 has the peephole 29 formed therein, the engagement piece 32 is inserted into the grating hole 13 while confirming that the tip 33 of the engagement piece 32 is positioned in the peephole 29. Further, the locking piece 32 is rotated until it is confirmed that the tip end portion 33 of the locking piece 32 appears in the peep hole 29 formed at the locking position.

When the locking piece 32 is thus rotated to the locking position and then the handle 42 is rotated by a predetermined amount, the locking piece 32 is fastened and locked to the lower surface of the grating 11, and the stanchion body is pressed so as to press the grating 11. A tightening force will be generated between 22 and the locking piece 32. Therefore, the stanchion body 22 is pressed against the grating 11 and integrally fixed in an upright state. Since the stanchion body 22 is held by the tightening force of the handle 42 in this manner, it is securely fixed to the grating 11 and does not fall.

When the stanchion body 22 is removed from the grating 11, the procedure reverse to the above-mentioned installation procedure is performed.

In addition, since the substrate 25 is provided at the lower end of the column 23, if the installation environment is acceptable, such as when it is installed indoors and does not receive cross winds, or the stanchion arrangement is not straight,
In the case where the compartments themselves are arranged in a square shape or a square shape and the rigidity can be maintained in the compartment itself, by removing the rod body 31 from the stanchion body 22, it is possible to place only the stanchion body 22 on the level ground as in the conventional case. . That is, the stanchion 21 can be fixed to the grating 11 without fail, or can be used as a normal stanchion only by the stanchion body 22, so that the stanchion 21 can be selectively installed according to the installation environment.

The peep hole 29 may be a substrate 25 having radial slits formed therein. Further, if the substrate 25 is formed of a transparent member such as an acrylic plate, the peephole 29 is unnecessary.

[Effects of the Invention] In summary, according to the present invention, the following excellent effects are exhibited.

(1) The stanchion can be reliably fixed to the grating by using the tightening force, and the stanchion can be prevented from falling.

(2) The stanchion itself becomes a stanchion,
Selective installation is possible according to the installation environment.
