付けるようにされた保安柵支柱の一例の使用状態
を示す説明図である。 The lining board placed over the excavation work area for conduit burying etc. may be removed for a period of time depending on the circumstances of the construction work, and security fences should be installed at the opening to prevent people and vehicles from entering. It will be done. Since such security fences are generally installed for a short period of time, it is desirable that the support posts of the security fence be able to be easily attached and removed, and that they be firmly attached. FIG. 1 is an explanatory view showing an example of a security fence post used for lifting a lining board, which is attached using a through hole formed in a corner of the post.

aを螺合させ覆工板Cをフツク12aとフランジ
20aで挟圧するように締付ける。 When attaching this security fence post to the lining plate C, rotate the hook 12a and attach the longitudinal direction to the screw 11.
After inserting the hook 12a into the through hole of the lining plate C, that is, the mounting hole C1 of the security fence post, turn the hook 12a so that its longitudinal direction is aligned with the axial direction of the screw 11a. Position them so that they are substantially orthogonal. Next, turn the handle 21a to tighten the tightening fitting 2.
a and tighten it so that the lining plate C is pinched between the hook 12a and the flange 20a.
ところで、この保安柵支柱は、締付金具2aと

覆工板を取外した開口部から転落の虞れもあり非
常に危険である。 By the way, this security fence post is different from the clamping bracket 2a by holding the handle 21 of the clamping bracket 2a while holding the hook 12a on the back side of the lining plate C in a predetermined position.
The work of rotating a is quite troublesome, and the tightening metal fitting 2
There is a risk that the screws may come loose due to insufficient tightening of (a) or vibrations from nearby traffic, and if you lean on the security fence post in such an unstable condition,
There is a risk of falling through the opening where the lining board has been removed, which is extremely dangerous.

ツパー113は支柱本体3の抜脱防止用である。 A lock pin 124 is fixed to the upper surface of the hook length protrusion 123 near the connecting portion of the connecting rod 11.
The length l 2 between the end surface 125 of the lock pin 124 and the side peripheral surface 112 on the short protrusion side of the connecting rod 11 is the third
As shown in the figure, it is slightly smaller than the diameter D of the security fence mounting hole C0 . The end surface 125 of the lock pin 124 and the side circumferential surface on the short protrusion 121 side of the connecting rod 11 are arranged so as to face the peripheral wall surface of the mounting hole C 0 , that is, the center of the mounting hole C 0 and the center of the connecting rod 11 is eccentric, so that even if the clamping plate 2 is rotated when mounting the base 1 on the lining plate C, the base 1 is prevented from rotating together with the clamping plate 2, and the clamping plate 2 is not rotated. Even if the support body 3 is turned after the attached plate 2 is tightened, the base body 1 is prevented from turning. Therefore, the base body 1 can be easily attached to the lining plate C. The short protrusion 121 is attached to the hook 1 as shown in FIG.
2 to pass through the mounting hole C0 , short protrusion 1
The dimension l 1 (Fig. 2) from the end surface 122 of the connecting rod 11 to the side peripheral surface 111 on the long protrusion side of the connecting rod 11 is the lining plate C.
The diameter of the mounting hole C0 (Fig. 3) is made slightly shorter than the diameter of the mounting hole C0 (Fig. 3). A stopper 113 fixed to the tip of the connecting rod 11 is used to prevent the column main body 3 from coming off.

固定させる。 To attach the above-mentioned security fence support to the lining plate C, first move the tightening plate 2 toward the support main body 3,
As shown in FIG. 3, the long protrusion 123 of the hook 12 is introduced into the mounting hole C 0 while being tilted, and the short protrusion 121 is inserted into the mounting hole C 0 while the base 1 is vertically erected. Then, pull up the base body 1 so that the lock pin 124 fits into the mounting hole C0 , rotate the tightening plate 2, and tighten the lining plate into the hook 1.
2 and the clamping plate 2 to fix the base 1 to the lining plate C.

ある。 As described above, in the security fence post mounting structure of the present invention, the hook 12 provided with the lock pin 124 is fixed to the base body 1 in a right angle direction with an offset in the longitudinal direction. Therefore, when installing a security fence post, all you need to do is tilt the post, insert the hook 12 into the mounting hole C0 , stand the post up, and turn the clamping plate 2. When clamping C, the mounting hole
Since the base 1 does not rotate within C 0 , the lining plate C
Easy to install and remove. Further, since the support main body 3 is further screwed onto the base body 1 which is fixed by the screwing of the tightening plate 2, the screws will not easily loosen even after installation due to vibrations or the like. In addition, by providing a through hole 32 in the upper part of the support main body 3, a metal rod can be passed through the through hole 32 and the support main body 3 can be inserted.
It is easy to fix the support main body 3 by turning the
Another advantage is that the rope can be stretched using the through hole 32.
