DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling structure of a reinforcing bar frame embedded in a gutter block.

[0002]

2. Description of the Related Art Reinforcing frames used for gutter blocks having left and right side walls and an upper wall extending between upper ends of both side walls and having a lid receiving opening formed between the upper walls are described. And left and right side reinforcing bars buried in the left and right side walls, and a connecting reinforcing material and an upper reinforcing bar buried in the upper wall.

[0003] After assembling the side rebar frame, the connecting rebar material, and the upper rebar frame, the rebar frame is set in a concrete formwork, and concrete is poured into the concrete form, whereby the rebar frame is buried. The manufactured gutter block is manufactured.

In this case, conventionally, when assembling the side reinforcing bar, the connecting reinforcing bar, and the upper reinforcing bar, these are connected by welding.

[0005]

However, when the side reinforcing bar, the connecting reinforcing bar, and the upper reinforcing bar are connected by welding as in the prior art, the assembling work takes time.
There was a problem that working efficiency could not be improved.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and is intended to assemble the side rebar frame, the connecting rebar material, and the upper rebar frame with a simple operation. It is an object of the present invention to provide a reinforcing frame for a gutter block.

[0007]

In order to solve the above-mentioned problems, a reinforcing frame for a gutter block according to the present invention comprises left and right side walls and an upper wall extending between upper ends of both side walls.
A reinforcing frame used for a side groove block in which a lid receiving opening is formed between both upper walls, and left and right side reinforcing bars embedded in left and right side walls, and embedded in the upper wall. It has a connecting rebar material and an upper rebar frame, and both ends of the connecting rebar material are connected to a side reinforcing frame by binding with a resin band, and the upper reinforcing frame is connected to the side reinforcing frame by binding with a resin band. The resin band has a band portion having a plurality of locking grooves formed on one surface in a streak shape, and a locking hole formed at a base end of the band portion. A locking claw is protruded, and a locking projection for engaging the locking claw with the locking groove is formed facing the locking hole.

In the present invention, the connection between the connecting reinforcing bar and the side reinforcing bar frame and the connection between the upper reinforcing bar frame and the side reinforcing bar frame are performed by resin band bonding. Therefore, the assembling work is simplified, and the working efficiency can be improved. That is, when the resin band is used, it is only necessary to pass the tip of the band portion through the locking hole while the band portion is wrapped around the reinforcing bar to be joined, and then tighten the band portion tightly. In this case, the locking projection of the locking claw protruding from the locking hole is engaged with the locking groove formed on one surface of the band portion, thereby preventing the band portion from being loosened. Instead of a resin band, for example, if the rebar is joined by wire binding, the wire must be wound around the rebar many times while tensioning the wire so that the wire hung on the rebar is not loosened. Work efficiency is poor due to labor and labor.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a main part of a reinforcing frame for a gutter block according to one embodiment, and FIG. 2 is a cutaway perspective view of a gutter block in which a reinforcing frame for a gutter block is embedded.

First, the gutter block will be described with reference to FIG. The side groove block 1 has left and right side walls 10 and 10.
And upper walls 11, 11 extending between upper ends of both side walls 10, 10. A lid receiving opening 12 is formed between the upper walls 11, 11, and generally has a free slope side groove. It is called.

Next, a reinforcing frame for a gutter block will be described with reference to FIGS. The reinforcing bar frame 2 includes left and right side reinforcing bars 20, 20 buried in left and right side walls 10, 10 of the side groove block 1, and connecting reinforcing bars 21, 21, 21 buried in the upper walls 11, 11. , 21 and upper rebar frames 22, 22, and are formed by assembling them.

The side reinforcing bar frame 20 is formed by welding a side main reinforcing bar 20a extending in the vertical direction of the side wall 10 and a side force reinforcing bar 20b extending in the length direction of the side wall 10. It is. In this case, the positioning reinforcing bar 20c of the upper reinforcing bar frame 22 is provided also as a side portion force bar.

The connecting reinforcing bar member 21 extends between the upper portions of the left and right side reinforcing bar frames 20, 20. Both ends of the connecting reinforcing bar member 21 are joined to the side reinforcing bar frame 20 by binding with a resin band 3. .

The upper reinforcing frame 22 extends between the upper ends of the left and right side reinforcing frames 20, 20, and includes an upper main reinforcing bar 22 a extending in the width direction of the upper wall 11, and a length of the upper wall 11. The upper force bars 22b extending in the direction are framed by welding. The four corners of the upper reinforcing bar frame 22 are joined to the side reinforcing bar frame 20 by binding with the resin band 4. In this case, the side main reinforcing bar 20a, the positioning reinforcing bar 20c, the upper main reinforcing bar 22a, and the upper The intersection with the force bar 22 b is joined by the resin band 3.

Next, as shown in FIG. 3, the resin band 3 is provided with a locking hole 31 at one end of a band portion 30 having a flat cross section.
A plurality of locking grooves 32 are formed on one surface of the band portion 30 in a streak shape, and a locking claw 33 is protruded from the locking hole 31 and engages with the locking claw 33. A locking projection 34 for engaging with the locking groove 32 is formed facing the locking hole 31. In use, it is only necessary to pass the tip of the band portion 30 through the locking hole 31 with the band portion 30 wrapped around the reinforcing bar to be joined, and then tighten the band portion 30 tightly. In this case, the locking projections 34 of the locking claws 33 projecting from the locking holes 31 engage with the locking grooves 32 formed on one surface of the band portion 30, and
Is prevented from loosening.

As described above, in the gutter block reinforcing bar 1, the connection between the connecting reinforcing bar 21 and the side reinforcing bar 20 and the connection between the upper reinforcing bar 22 and the side reinforcing bar 20 are made of the resin band 3.
This is done by binding. Therefore, the assembling work is simplified, and the working efficiency can be improved.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this. For example, the number of side main reinforcing bars and side force bars constituting the side reinforcing bar frame and the number of upper main bars and upper force reinforcing bars forming the upper reinforcing bar frame are determined according to the size of the gutter block.

In the embodiment, the cross-section of the resin band is formed in a flat shape, but the cross-section of the band may be circular, elliptical, triangular or square.

[0019]

As described above, in the reinforcing frame for the gutter block of the present invention, since it is assembled using a resin band, unlike the conventional case, the time required for welding can be saved, and the time required for welding can be reduced. The effect that the side rebar frame, the connecting rebar material, and the upper rebar frame can be assembled without loosening is obtained.
