Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a security fence mounting bracket.

[Prior art and problems with the invention] In order to ensure a safe passage in civil engineering work, it is necessary to provide safety fences on both sides of the passage, and safety fence mounting brackets are sometimes used to construct the safety fences.

By the way, in trench excavation work, etc., it is sometimes necessary to cover the trench with a safety net (safety net for fall prevention) in addition to constructing a safety fence. In this case, in the past, a special safety net mounting bracket was used to install the safety net, and a safety net mounting bracket was required in addition to the safety fence mounting bracket.
Construction work was troublesome, and storage of the metal fittings was also troublesome.

[Means for Solving the Problems] The safety fence mounting bracket according to the present invention can eliminate the above-mentioned disadvantages, and a stanchion arm with a setting bolt is fixed to the lower part of the plate-shaped base, and the above-mentioned plate-shaped base Clamps for fixing security fence posts and hooks for tensioning safety nets are arranged and fixed on both upper sides of the safety fence so that these clamps and hooks are facing each other with the plate-shaped base in the middle. This is a configuration characterized by the following.

[Example] The present invention will be described below based on drawings showing examples.

FIG. 1A, FIG. 1B, and FIG. 1C are a front view, a side view, and a plan view, respectively, showing an embodiment of the safety fence mounting bracket of the present invention.

1A to 1C, reference numeral 1 denotes a plate-like base, and a stanchion arm 2 having a cross-sectional shape is located at the bottom of the base, as will be described later, between one piece of the arm 2 and the side surface of the plate-like base 1. Other pieces are welded and fixed so that the upper ends of the sheet piles can be clamped together. Arm 2 above
A setting bolt 3 is provided on one of the pieces.

Reference numeral 4 denotes a hinge type clamp for fixing the security fence post, and is fixed by welding to one side of the upper part of the plate-shaped base 1.

5 is a U-shaped hook for tensioning the safety net;
The clamp 4 is welded and fixed to the other side of the upper part of the plate-shaped base 1 so as to be back to back to each other. A hook-shaped protrusion 51 is formed on the upper part (tip) of the U-shaped hook 5 so that the stretched safety net will not easily come off as described later.

Figure 2 shows how the metal fitting of the present invention is used.
A is an excavation groove, B is a sheet pile, and a sheet pile clamping portion configured between one piece of the stanchion arm 2 of the metal fitting of the present invention and the side surface of the plate-shaped base 1 is locked to the upper end of the sheet pile B; It is fixed with a set bolt 3. Here, the hinge type clamp 4 installed on the metal fittings
The safety fence posts C are supported by the U-shaped hooks 5, and the safety net D covering the groove A is stretched by the U-shaped hooks 5. E,... are security fence handrails.

The metal fittings of this invention can be used for purposes other than the above-mentioned trench excavation work. For example, when constructing a safety fence between the decks (overhanging scaffolding) that are temporarily installed during bridge construction work, a safety fence can be installed on the edge of each deck, and construction materials can be used between the decks. It can also be used to set up safety nets to prevent falls.

FIG. 3 shows the metal fitting of the present invention and its usage when applied to the above-mentioned bridge construction work. In this metal fitting, a stanchion arm 2 having a cross-sectional shape of The edge of the deck base plate F is fixed by welding between the two opposing pieces of the square arm 2, and after the edge of the deck base plate F is sandwiched between the two opposing pieces of this It is fixed by a setting bolt 3 provided in one piece.

In FIG. 3, reference numeral 4 indicates a hinge-type clamp for fixing the security fence posts, and reference numeral 5 indicates a U-shaped hook for tensioning the safety net. They are welded and fixed to each other back to back with the plate-shaped base 1 in the middle. C is a security fence post, and D is a safety net.

[Effects of the invention] As described above, according to the safety fence mounting fittings according to the present invention, the common fittings can be used for constructing not only safety fences but also safety nets in trench excavation work, bridge construction work, etc. This has the advantage that construction work can be greatly simplified and the storage of these metal fittings can be facilitated, compared to the conventional example in which dedicated metal fittings are used for each of the safety fence and the safety net.

In particular, in the mounting bracket of the present invention, the clamp for fixing the security fence support and the hook for tensioning the safety net are
Because they are arranged and fixed on both sides of the upper part of the plate-shaped base so that they are back to back, the entire fitting can be constructed compactly and is easy to handle.Moreover, it is possible to carry out the work of fixing the support and the work of stretching the net at the same time. This has the practical effect of allowing these operations to be carried out without any problems.

Furthermore, since the stanchion arm with a setting bolt is fixed to the lower part of the plate-like base, there is an advantage that it can be attached and fixed to a sheet pile or deck base plate very easily.

[Brief explanation of the drawing]

Figure 1A is a front view showing an embodiment of the safety fence mounting bracket according to the present invention, Figures 1B and 1C are a side view and a plan view of the same bracket, respectively, and Figure 2 is the use of the bracket of the present invention. FIG. 3 is an explanatory diagram showing another embodiment of the safety fence mounting bracket according to the present invention. In the figure, 1 is a plate-shaped base, 2 is a stanchion arm, 3 is a set bolt, 4 is a clamp for fixing a security fence post, and 5 is a hook for tensioning a safety net.

Claims (1)

[Scope of utility model registration request] A stanchion arm with a setting bolt is fixed to the lower part of the plate-shaped base, and a clamp for fixing the security fence support and a hook for tensioning the safety net are attached to both sides of the upper part of the plate-shaped base, and these clamps and hooks are attached. A security fence mounting bracket characterized in that the plate-shaped base is arranged and fixed to each other so as to be back to back with the plate-shaped base in the middle.
