Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a steel pipe fixing fitting for barricades.

(Prior Art) Fig. 4 shows a conventional fixing device for a steel pipe to a barricade, A indicates a barricade, and a pair of angle steel opening/closing leg pieces 2, 2 are attached to both ends of the top horizontal piece 1.
are pivoted in an inverted V-shape, and when both leg pieces 2 are expanded, a horizontal opening stopper piece 3 is connected via a pin across both leg pieces 2, and the opposing legs extend in the direction of the top horizontal piece 1. A horizontal connecting member 4 is connected between the pieces 2 through pins. In the figure, 5 is a sign piece suspended from the top horizontal piece 1.

Therefore, when fixing steel pipe B to barricade A in order to prevent the movement of barricade A or the entry of unauthorized personnel during work, a steel wire C of approximately 3 mm is used.
Both A and B were bound together by.

(Problem that the invention aims to solve) However, it takes a lot of effort to fix steel pipes to barricades with iron wire, and the cut surface of the iron wire is sharp, so workers have to cut the iron wire while working. There were cases where people were injured by the mask.

(Means for Solving the Problems) The present invention relates to a steel pipe fixing hardware for barricades proposed to solve the above-mentioned problems.
A hook-shaped part that is attached to the opening/closing leg piece on the side part of the barricade is curved, and an inclined piece that is attached to the side surface of the steel pipe is extended from the base end of the horizontal piece through the twisted part, and the inclined piece is attached to the side surface of the steel pipe. By bending the tip of the hook to engage the horizontal opening stopper that connects the opening/closing leg pieces, the barricade steel pipe can be quickly and safely fixed to the barricade, thereby solving the problem mentioned above. This is to solve the problem.

(Function) Since the barricade steel pipe fixing fitting according to the present invention is configured as described above, the pair of opening/closing leg pieces of the barricade can be expanded, and the barricade can be opened between the horizontal opening stopper pieces that connect the two leg pieces. The horizontal piece is attached to the upper surface of the steel pipe, and the hooked end of the horizontal piece is hooked to the leg piece of the barricade, and the inclined piece is attached to the side of the steel pipe. The steel pipe is quickly and reliably fixed to the barricade via the fixing fitting of the present invention by engaging the tip hook-shaped portion with the horizontal opening stopper piece that connects the pair of opening/closing leg pieces of the barricade. .

(Example) The present invention will be described below with reference to the illustrated embodiments.

Reference numeral 11 denotes a horizontal piece attached to the upper surface of the steel pipe for the barricade, and a hook-shaped part 1 is attached to the tip of the horizontal piece to be attached to a pair of inverted V-shaped opening/closing legs 2 made of angle material in the barricade.
2 is composed.

An inclined piece 14 extending downward from the base end of the horizontal piece 11 via the twisting part 13 is provided at the tip end of the inclined piece 14. A hook-shaped portion 15 that engages with the horizontal stopper piece 3 is curved.

Since the illustrated embodiment is configured as described above, the opening/closing leg pieces 2, 2 are expanded in an inverted V shape on both left and right sides of the barricade A, and the horizontal opening stopper piece 3 is connected between the opening/closing leg pieces 2, 2 and 2, 2. . By attaching the part 12 to the leg piece 2, further attaching the inclined piece 14 of the fixture to the side surface of the steel pipe B, and attaching the hook-shaped part 15 at the tip to the horizontal opening stopper piece 3, The steel pipe B can be easily and quickly attached to the barricade A via the fixture.

(Effect of the invention) As described above, the steel pipe fixing fitting for barricades according to the invention consists of a slanted piece extending from the base end of the horizontal piece having a hooked part at its tip via a twisted part. Since it is configured with a hook-shaped part curved at the tip, it is suitable for barricades in which the horizontal piece and the inclined piece are mounted across the horizontal opening stopper piece that connects the respective opening/closing leg pieces on both the left and right sides of the barricade. The steel pipe can be easily and quickly barricaded by attaching it to the top and side surfaces of the steel pipe, and by engaging the hook-shaped portions at the ends of the horizontal and inclined pieces to the leg pieces and the horizontal stopper pieces, respectively. Can be installed.

Furthermore, since the barricade steel pipe fixture according to the present invention does not have a sharp cut surface unlike the conventional binding wire, there is no risk of injury to workers during the work, and the work can be performed safely.
