[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for holding a wire mesh or a reinforcing bar used as a reinforcing material at a certain distance from the ground in a slope protection work or the like.

[0002]

2. Description of the Related Art Concrete spraying is known as a slope protection method. In this method, a thick wire mesh is laid on the slope, and then concrete is sprayed on the entire mesh surface,
It is a method of covering the surface of the ground with concrete. Further, conventionally, a block-shaped spacer has been used to hold the wire mesh at a certain height around the ground.

[0003]

[Problems to be Solved by the Present Invention] Problems to be solved by the present invention are as follows. <A> Since the spacer is a block body made of concrete, it is relatively heavy. Therefore, the work of transporting the spacer to the site where the scaffolding has a bad slope is extremely laborious.

<B> When arranging the spacers, the spacers will not be stable and the position will be displaced unless the construction site is leveled, and thus some leveling is required.

<C> When it is necessary to move or add a spacer after the wire net is placed on the spacer, it is very difficult to move or add the spacer while the wire net is laid.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a spacer having excellent operability and capable of stably holding a held body.

[0007]

[Means for Solving the Problems] That is, according to the present invention, a pair of support legs formed by bending a single wire rod and spreading in a divergent shape, a resilient portion formed between the upper parts of the both legs, and a support And a space for accommodating an object to be held, which is formed between both legs by bending the upper part of the leg outward.

[0008]

First Embodiment The present invention will be described below with reference to the drawings.

<A> Overall Configuration FIG. 1 shows an example of a spacer 1 according to the present invention. The spacer 1 is basically composed of a circular elastic portion 2 and a pair of support legs 3 and 4, which are integrally formed by bending a single steel wire. Each support leg 3 and 4 is a vertical line portion 3
1 and 41, and landing portions 32 and 42 that are horizontally bent from the ends of the vertical line portions 31 and 41. On the upper part of the vertical line portion 31 of the one support leg 3, a jaw portion 33 is formed which is bent in a C shape and has a recess space. This jaw 33
The holding space 6 is formed by the vertical line portion 41 of the other support leg 4 that closes the opening of the jaw 33.

<B> Resilient part The resilient part 2 has a function of keeping the holding space 6 in a normally closed state,
It is a part that also has the function of measuring the covering thickness of shotcrete. The elastic portion 2 is not limited to a circular shape, but may be a rectangular shape, a triangular shape, or an oval shape.

<C> Holding Space Since the holding space 6 is a part which supports the wire mesh 5 and the like to be held at a certain distance from the slope while preventing the held object from falling off, the size of the holding space 6 is large. In consideration of the wire diameter of the wire material to be formed, its height is also determined based on the planned support height of the held object such as the wire mesh 5.

[0012]

Next, a method of constructing a slope using the spacer 1 will be described with reference to FIGS.

<A> Laying a wire mesh A wire mesh 5 is laid on the slope 7 to be protected. In the present invention, the wire mesh 5 is placed directly on the slope 7.

<B> Setting of Spacer In order to separate the wire net 5 from the slope 7, it is sufficient to partially lift the wire net 5 slightly and push the spacer 1 from above the wire net 5. As a method of setting the spacer 1 on the wire mesh 5, the elastic portion 2 is held by hand, and the intersection of both legs 3 and 4 of the spacer 1 is pressed against the wire material forming the wire mesh 5, and this wire material is held in the holding space 6 of the spacer 1. The elastic member 2 can be set by opening the elastic member 2 or holding the elastic member 2 in the diameter reducing direction to open the holding space 6 and accommodating the wire material constituting the wire net 5 in the holding space 6. . In this way, the spacer 1 is attached to the wire mesh 5 to attach the wire mesh 5 to the slope 7
Away from. The weight of the wire net 5 is the jaw 33 and the elastic portion 2.
The legs 3 and 4 are supported through the same, and the vertical line portion 41 of the straight leg 4 closes the holding space 6 and restrains the wire mesh 5 from falling off.

<C> Concrete spraying Finally, concrete 8 is sprayed on the entire surface of the wire netting 5 to complete the construction. When the concrete 8 is sprayed, the sprayed thickness of the concrete 8 can be measured by the elastic portion 2 of the spacer 1, and the spacer 1 is finally buried together with the wire net 5.

[0016]

[Embodiment 2] FIGS. 3 and 4 show spacers 1a and 1b corresponding to a case where the held body is a reinforcing bar 9. The spacer 1a of FIG. 3 has basically the same structure as the spacer 1 of the above-mentioned embodiment, except that the vertical line portion 41 of the other support leg 4 is formed with a curved portion 43 that is curved outward. By doing so, not only the wire netting 5 but also the reinforcing bar 9 having a large diameter can be supported. In the case of the spacer 1a shown in FIG. 3, the weight of the reinforcing bar 9 is supported by the jaw portion 33, and at the same time, the weight of the reinforcing bar 9 is supported by the contracting force of the elastic portion 2 through both legs 3, 4.

As shown in FIG. 4, bilaterally symmetrical curved portions 33 and 43 are formed on both legs 3 and 4, and the curved portions 33 and 4 are formed.
The reinforcing bar 9 may be supported by 3. Spacer 1b of this embodiment
Is not limited to supporting the reinforcing bar 9 and may be used to support the wire net 5. In the case of the spacer 1b of FIG. 4, the weight of the reinforcing bar 9 is supported only by the diameter reducing force of the elastic portion 2 via the curved portions 33 and 43. The present embodiment is convenient when reinforcing bars 9 are arranged on the upper and lower sides of the wire mesh 5.

[0018]

Third Embodiment The spacers 1, 1a, 1b may be formed by bending a single wire into double or more as shown in FIG. 5, for example.

[0019]

Since the present invention has been described above, the following effects can be obtained.

<B> Since the spacer is lightweight, it can be easily transported to a slope, and since it has a simple shape, it is excellent in mass productivity.

<B> While the spacer can be attached and detached satisfactorily, the object to be held can be reliably supported while being prevented from falling off.

<C> Spacers can be easily moved and added, and workability is improved.
