Description

  The present invention relates to a work tool for performing work on slab bars used in reinforced concrete floor construction work or the like.

  The work performed on the assembled slab reinforcement includes, for example, placing slab concrete.

Regarding work tools on rebars, the following patent documents are also proposed as work tools that can be used at work sites where rebars are bound, and can be bound and moved on rebars while sitting. As shown in FIG. 6, the work chair 1 includes a base part 2 of a size that can be seated by an operator and two pieces arranged in parallel on the back surface of the base part so as to roll on the reinforcing bar 3. The metal roller 4 and the seat portion 5 installed on the upper surface of the base portion are provided, and the axial length of the roller 4 is set to be longer than the arrangement interval of the reinforcing bars 3. In this state, the roller 4 can be moved to move on the rebar 3 to work.
Utility Model Registration No. 3136200

  Although the said patent document 1 was proposed as a working chair which an operator sat down and used on the arranged reinforcing bar in the work site which binds a reinforcing bar, in addition to this, on slab reinforcement In order to secure a working scaffold when placing concrete or the like, a temporary passage safety mat 7 assembled on a lattice with steel bars 6 as shown in FIG. 5 may be used.

  This temporary passage safety mat 7 is laid on the rebar 3 with assembled slab rebars, and serves as a passage for workers to sit on and walk on.

  When working on slab reinforcement (concrete placement, etc.), using tabi (underground socks) only touches the width of the reinforcing bars, which increases the support pressure on the soles and hurts the soles.

  In safety shoes, it is easy to slip. Even when the safety mat 7 for the temporary passage is used, if the steel rod 6 itself is a round bar, the safety shoes on the steel rod 6 are easily slipped. Although it is eliminated, especially in the case of raw concrete, the mat 7 is not fixed to the reinforcing bar 3 because the mat 7 is removed as the concrete is launched, so the mat 7 is easy to slide on the reinforcing bar 3 and the operator may become unstable. There is.

  The object of the present invention is to eliminate the inconvenience of the conventional example, and when working on the slab reinforcement, it does not slip and can maintain a stable state, and it can be worn on the foot and used as a shoe. It is intended to provide a work tool on the slab muscle that can be effectively supported by both feet by attaching it to both feet and that is easy to move and use.

  In order to achieve the above object, the present invention according to claim 1 is a work tool for working on an assembled slab bar, wherein a reinforcing bar engaging recess for the slab bar is formed on the bottom surface. The gist of the invention is that an overshoe body is provided above the sole so that the on-site work shoes can be put on.

  According to the first aspect of the present invention, since the field work shoes can be inserted into the overshoe body portion, the field work shoes can be used by being attached to the field work shoes, and the slab bars are stored in the reinforcing bar engaging recesses formed on the bottom of the shoe sole. Thus, it can be locked so as not to slide on the slab muscle, and when working on the slab muscle, both feet can be fixed to the slab muscle and a stable state can be maintained.

  Furthermore, since it can be worn on the left and right feet, it can be performed easily by moving the feet to move.

  The gist of the present invention described in claim 2 is that the overshoe body and the shoe sole are separated from each other in a vertical relationship with a space therebetween and are coupled to each other so as to be rotatable.

  According to the second aspect of the present invention, since the foot including the overshoe body can freely rotate with respect to the shoe sole engaged with the slab muscle, an unreasonable posture is not forced.

  The gist of the present invention described in claim 3 is that the reinforcing bar engaging recesses of the shoe sole are formed in a cross shape in the crossing direction.

  According to the third aspect of the present invention, the slab bars are in the form of a lattice, and the vertical bars and the horizontal bars are crossed by the binding lines in the horizontal direction. It may be housed in a concavity and can take a more stable posture.

  The gist of the present invention described in claim 4 is that the shoe sole has a degree of rigidity that transmits the support pressure from the reinforcing bars to the whole.

  According to the fourth aspect of the present invention, since the shoe sole has such a degree of rigidity that it transmits the support pressure from the reinforcing bar to the whole, even if only the width of the reinforcing bar is grounded, the support pressure of the sole acts on the whole. Can be made.

  As described above, the work implement on the slab muscle of the present invention does not slip when working on the slab reinforcement, and can be maintained in a stable state and used as a shoe when worn on the foot. Because it can, it can support both feet effectively and is easy to use.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of a working tool on a slab bar according to the present invention, FIG. 2 is a rear view thereof, and FIG. 3 is a bottom view thereof.

  The work tool on the slab muscle of the present invention is composed of a combination of a shoe sole 8 and an overshoe body 9 to which the shoe sole 8 is attached.

  The shoe sole 8 will be described first. The shoe sole 8 has a shape similar to or equivalent to that of a shoe sole such as an ordinary rubber boot or the like, and is formed with an uneven portion 12 for preventing slipping in a corrugated shape or other shapes.

  In the present invention, on the bottom surface of the shoe sole 8, reinforcing bar engaging ridges 10, 10 'to the reinforcing bars of the assembled slab bars are formed.

  Of these, the reinforcing bar engaging groove 10 is a groove that crosses the shoe sole 8 in the length direction, and the reinforcing bar engaging groove 10 'is a groove that crosses the shoe sole 8 orthogonal to the reinforcing bar engagement groove 10 in the width direction. It becomes.

  Here, the concave line is a generic name for the continuous concave line, and there is a variation as shown in FIG. 4 in the reinforcing bar engaging groove 10, 10 'as an embodiment. FIG. 4A shows a case where a V-shaped groove is used. When a part of the reinforcing bar (upper side) is accommodated in the length direction, FIG. 4B shows a case where the reinforcing bar is fitted and accommodated as a groove, and FIG. Is drawn, and the rebar is in contact with the apex.

  Note that the concave stripe may have a rectangular cross section. In the figure, reference numeral 15 denotes a rough surface provided on the inner surface of the concave strip as a slip stopper.

  The slab bars are the vertical bars and the horizontal bars are crossed by the binding line in the horizontal direction. The horizontal bars are located on the lower side of the vertical bars. In the fitting, the reinforcing bar engaging recess 10 'is fitted with a horizontal bar located on the lower side.

  The reinforcing bar engaging recesses 10 and 10 'only need to have a width and depth sufficient to accommodate the reinforcing bars 11 constituting the slab bars, and the reinforcing bar engaging recesses 10 and the reinforcing bar engaging recesses 10' have the same depth. However, the reinforcing bar engaging groove 10 may be smaller than the reinforcing bar engaging groove 10 ′, and the reinforcing bar engaging groove 10 ′ may be approximately twice as deep as the reinforcing bar engaging groove 10.

  The sole 8 is made of synthetic rubber, synthetic resin, wood, or the like, and is selected to have a degree of rigidity that can transmit the support pressure from the reinforcing bar 11 to the whole.

  The relationship between the sole 8 and the overshoe body 9 to which the sole 8 is attached is that the upper attached to the sole corresponds to the overshoe body 9, and the sole 8 forms the sole of the overshoe body 9. In the illustrated embodiment, the overshoe body 9 and the sole 8 are formed as separate bodies.

  The shoe sole 8 and the overshoe body 9 are in a vertical relationship with a space therebetween, and the shoe sole 8 raises a coupling column 13 to the overboot 9 at the center of the upper surface. The coupling column 13 includes a core column 13 a such as a metal pipe, and covers the outside with the same material as that of the shoe sole 8 so as to have a sense of unity as a part of the shoe sole 8.

  The overshoe body 9 may be flat or deep as long as it can be worn with on-site work shoes, but in the illustrated example, it has an opening 9a on its upper surface. The field work shoes 14 were inserted from 9a so that the field work shoes 14 could be put on from above.

  Although not shown, the opening 9a can be provided with a band, a Velcro (trademark) hook and loop fastener, or other convenient fixing device for holding the instep portion of the inserted field work shoe 14.

  As an example of this fixing device, the field work shoe 14 normally includes a protective iron plate that covers the toe portion of the foot, but a magnet is attached to the upper and back sides of the front side of the overshoe body 9 to fix the field work shoe 14. It is also possible to do. The magnetic force of the magnet is such that it does not hinder the on-site work shoe 14 from being attached to and detached from the overshoe body 9.

  The material for forming the overshoe body 9 is also not particularly limited, such as synthetic rubber, synthetic resin, synthetic leather, and the bottom part has an appropriate hardness and thickness, and there is an arch-like space as an arch 9b. The coupling column 13 is disposed by using the coupling column 13 and is coupled to the shoe sole 8 via the coupling column 13 so as to be rotatable. A bearing may be interposed in the pivotable coupling, or the coupling pillar 13 may be a bearing.

  Even if the overshoe body 9 and the shoe sole 8 are separated from each other and have a vertical relationship, the distance between the overshoe body 9 and the shoe sole 8 is not particularly limited. I'm sorry.

  The toe lower surface and the heel lower surface of the bottom surface of the overshoe body 9 can be brought into contact with the upper surface of the shoe sole 8.

  It is not necessary for the overshoe body 9 and the shoe sole 8 to have the same or similar outer shape. In particular, the shoe sole 8 has a footwear shape as shown in the figure, and can be of any shape, such as circular or rectangular. Something like that.

  Next, usage will be described. The work tool on the slab muscle according to the present invention is attached to the field work shoes 14 such as boots and is a pair of left and right pairs.

  The on-site work shoes 14 are inserted from the openings 9 a and the on-site work shoes 14 are stored in the overshoe body 9.

  Then, the reinforcing bar engaging recess 10 or 10 ′ is fitted to the reinforcing bar 11, and the worker stands on the slab bar and performs operations such as concrete placement.

  When moving, if the foot is lifted, the work implement on the slab bar of the present invention can be lifted together with the on-site work shoes 14, and the bar is moved to another place and the reinforcing bar engaging groove 10 or 10 ′ is similarly fitted to the bar 11. Just stop.
