Abstract

PROBLEM TO BE SOLVED: To provide a clamping metal fitting, by which the fixing section of a barricade stand and a holder and holding-attaching body are not damaged even when a fixed value or more of pushing-down force and tensile force are applied to a steel pipe under an unstable state. SOLUTION: A nut 15 is fitted and clamped to a mounting bolt 14 inserted into a through-hole 12 formed to a mount 1 for the barricade stand S from a through-hole 11 formed to the base 4a of a holder 4 through a deforming member 13. The deforming member 13 is used as a washer in which strength is weakened positively, or a spring material. The deforming member 13 is interposed on the mount 1 side of the barricade stand S.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a construction site,
The present invention relates to a binding bracket for a barricade stand mainly used for security at a road construction site or the like.

[0002]

2. Description of the Related Art In a conventional barricade stand, as shown in FIG. 9, for example, a horizontal rail 22 is bridged near a lower portion of a substantially inverted U-shaped support leg 21, and a top 21
a, and if necessary, a fastener 23 is fixed to a substantially central portion of the horizontal rail 22 by welding or the like. In order to use this barricade stand, as shown in FIG. 10, a plurality of these are arranged at predetermined intervals, steel pipes 24 are laid horizontally between the stands, and these steel pipes 24 are fastened to each other. By fixing with the bracket 23,
I am building a barricade.

As shown in FIG. 11, the binding member 23 is provided at one end of a holding member 25 having a substantially L-shaped side surface with a holding member 26 having a substantially arc-shaped side surface. One end is pivotally supported by a pin 27. Further, a bolt 28 pivotally supported at the other end of the holding body 25 is inserted into a notch 29 provided at the other end of the holding body 26, and a nut 30 is screwed into the bolt 28, thereby holding the holding body 25. The steel pipe 24 is held and fixed by the holding body 25 and the holding body 26.

[0004]

When assembling a barricade using this kind of barricade stand, first, the top 2 of the support leg 21 of the barricade stand is used.
When one end of the steel pipe 24 is fixed to the tie 23 fixed to 1a, an unstable state as shown in FIG. 12 is obtained.
Also, when the assembled barricade is dismantled, an unstable state as shown in FIG. 12 occurs during the disassembly. In particular, when an operator assembles or disassembles a barricade alone, it is impossible to avoid such an unstable state.

However, in such a state,
When a certain amount of pushing-down force or pulling force is applied to the steel pipe 24, there are many cases where the fixing portion of the fastening member 23 to the barricade stand and the holding member 25 and the holding member 26 of the fastening member 23 are damaged. Then, if these breakage occurs, there is a problem that the repair is very difficult and the tie 23 cannot be used again.

Accordingly, the present invention is to solve the above-mentioned conventional problems, and even if the steel pipe is subjected to a certain force of pushing down or pulling in an unstable state, a portion fixed to the barricade stand and a holding member are held. The object of the present invention is to provide a tying member that does not damage the body and the body.

[0007]

For this reason, the tying member for a barricade stand according to the present invention has a through hole 11 formed in the bottom surface 4a of the holder 4 and a through hole 12 formed in the installation stand 1 of the barricade stand S. A nut 15 is fitted to a mounting bolt 14 inserted with a deformable member 13 interposed therebetween and tightened.

[0008] Further, in the binding member for a barricade stand according to the present invention, the deformable member 13 may be a washer whose strength is positively weakened, or may be a spring material.

Further, in the tying member for a barricade stand according to the present invention, the deformable member 13 may be interposed on the installation table 1 side of the barricade stand S.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a binding device for a barricade stand according to the present invention.

As shown in FIGS. 1 and 2, in the tying member for a barricade stand according to the present invention, two support legs 2 are attached below an installation table 1, and a horizontal bar 3 is provided near the lower portion of the support legs 2. The barricade stand S is attached to a substantially central portion of the installation stand 1 of the barricade stand S as described below. The barricade stand S may have two support legs 2 that can be freely opened and closed as shown in FIG. 1, but as shown in FIG. 2, the two support legs 2 are made of synthetic resin. As an integral molding of
It may be a form that is always open. Further, the tying member for a barricade stand of the present invention may be attached to a substantially central portion of the horizontal bar 3 as necessary.

As shown in FIGS. 3 to 8, the tying member for a barricade stand of the present invention has a holding member 4 having a substantially L-shaped side surface, and a holding member 4 having a substantially arc-shaped side surface. One end of the body 5 is pivotally supported by a pin 6. Further, a bolt 8 is inserted from a through hole 7 provided at the other end of the holding body 5, and the bolt 8 is tightened into a cap nut 9 provided inside the other end of the holding body 4, thereby holding the holding body 4. The steel pipe 10 is held by the holding body 4 and the holding body 5.

[0013] The tying member for a barricade stand according to the present invention has a through hole 11 formed in the bottom surface 4a of the holder 4 and a through hole 12 formed in the installation stand 1 of the barricade stand S.
The nut 15 is fitted to the mounting bolt 14 inserted with the deformable member 13 interposed therebetween and tightened, whereby the barricade stand S is attached to a substantially central portion of the installation table 1.

As shown in FIGS. 3 and 4, the deformable member 13 may be a bowl-shaped washer whose strength is positively reduced by, for example, being made of relatively thin metal. The plate-like washer can also be a weakened plate, as shown in FIG. When such a bowl-shaped or plate-shaped washer is used, the bowl-shaped or plate-shaped washer is deformed by a certain or more pushing force or pulling force applied to the steel pipe 10, and these forces are absorbed. The fixed portion of the stand S to the installation table 1 and the holding body 4 and the holding body 5 are not damaged. Note that the deformed bowl-shaped or plate-shaped washer can be easily replaced with a new one, so that the restoration is very easy.

Further, the deformable member 13 can be a spring material such as a conical coil spring as shown in FIGS. When such a spring material is used, the spring material is deformed by a certain depressing force or a pulling force applied to the steel pipe 10, and these forces are absorbed, so that the barricade stand S is fixed to the installation table 1 at a fixed portion. Also, the holder 4 and the holder 5 are not damaged. The deformed spring material returns to its original shape when the pushing-down force or the pulling force is not applied, so that the spring material is not damaged and does not need to be replaced with a new one.

The deformable member 13 is interposed on the installation table 1 side of the barricade stand S, as in the embodiment shown in FIGS. It is preferable because a place can be easily secured, but it may be provided on the holding body 4 side.

[0017]

As described above, the tying member for a barricade stand according to the present invention is constructed as described above. Therefore, even if the steel pipe is subjected to a certain force of pushing down or pulling in an unstable state, the barricade stand can be connected to the tie. Of the sticking part of
The holding body and the holding body did not break.
