Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a mounting tool for mounting a double-legged construction site display plate on a guardrail.

(Prior art) When a conventional double-legged construction site display board is installed orthogonally to a guardrail, a distance corresponding to the dimension between the legs of the display board is set across the rail in a direction perpendicular to the guardrail. The two methods are to stand up and tie each leg of the signboard to the pile with a numbered wire, etc. and fix it, and to prevent the fall due to wind pressure etc. It is being appreciated.

(Problems to be solved by the invention) However, in the conventional method of fixing the display board, it takes a lot of labor and time to construct a pile or fix it with a numbered wire, and it is difficult to remove the display board after the construction is completed. However, there were many problems such as it was very troublesome to remove and clean up the piles.

(Means for Solving Problems) The present invention provides a double-legged construction site display panel mounting tool that solves these problems. A vertically elongated tubular upper pillar has a screw rod-shaped lower portion at its lower end. In order to enable the connecting rod to slide to the left and right and to be fixed at an appropriate position, a column is continuously provided and an upper end of the upper column is provided with a display plate receiving frame body including a connecting rod having pedestal holding metal fittings at both ends. A guardrail upper holding body that is installed orthogonally and fits and is vertically fixed by fitting to the above-mentioned strut, and a lower strut that is vertically movable and faces the above-mentioned guardrail upper holding body, and can be positioned at any height by an adjusting nut. A guard rail lower gripping concrete is provided, which is clamped and fixed to the guardrail by the guardrail upper and lower gripping concrete upper and lower clamp metal fittings, and both legs of the display board are inserted and displayed on the pedestal holding brackets on both sides of the display board receiving frame. Guardray the plate It is to be attached to the cable.

The structure and operation of the present invention will be described below with reference to the embodiments shown in the drawings.

From FIGS. 1, 3, and 4, a rectangular tube shape slidably fitted along the outer peripheral surface of the upper support column (3), and a holding tool shaft insertion hole of the upper support column (3). (2), (2) ... The lower part of the side wall part (21) on the side is the cut part (22), and the part above the intermediate lower part of the opposite side wall parts (23) is the cut part (24), and the side wall. Locking shaft that penetrates the center of the part (21) at a right angle and has the tip part slightly projecting into the cylinder, and the lower peripheral surface of the projecting part is an inclined surface (25) directed downward toward the side wall part (21). The upper holding tool shaft rod (27) fixed to the outside of the side wall portion (21) so as to project to the proper size by forming the portion (26), the upper holding metal fitting (28) made of the channel material is provided with the holding groove portion (29). Downward, and the outer side surface central part of one side wall part (30) is welded at a right angle to form a guardrail upper holding body (31), and the upper holding body (3
Tilt (1) as shown by the chain line (31 ') in Fig. 5 and upper column (3).
The holding shaft (26) so that the locking shaft (26) corresponds to any holding tool shaft insertion hole (2) and the tilt of the upper holding body (31) is returned to the vertical direction to hold the locking shaft (26). Insert it into the shaft insertion hole (2)
The guardrail upper holding body (31) is parked at the required position of (3). Cylindrical slide ring slidably inserted in the lower column (4)
On the side peripheral surface of (32), a lower holding tool shaft rod (3
3) Weld one end of the shaft rod (33) to the other end and hold a lower holding metal fitting (34) made of a channel material so as to face the upper holding metal fitting (28) of the guardrail upper holding body (31). The guard rail lower holding body (36) is constructed by welding with the groove (35) facing upward, and the sliding ring (32) of the holding body (36) is inserted into the lower strut (4), and the lower part is placed below it. Adjustment nuts (37) that thread onto posts (4)
