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 buried in a sewer block.

[0002]

2. Description of the Related Art Reinforcement frames used for culvert blocks in which a pipe channel is surrounded by left and right side walls and upper and lower walls include a main body reinforce frame buried over the entire wall, and a lower wall and an upper wall. Has a large number of reinforcing bars buried in the width direction. Then, after reinforcing bars are respectively connected to the main frame, the reinforcing bars are set on a concrete form via spacers, and concrete is poured into the concrete form, thereby producing a sewer block in which the reinforcing frame is embedded. You. In this case, in the related art, the reinforcing reinforcing bars are respectively connected to the main reinforcing frame by welding.

[0003]

However, as in the prior art, if a reinforcing bar is joined to a main bar frame by welding, the assembling work is troublesome and the work efficiency cannot be improved. Was. Therefore, prior to the present application, the present applicant has already proposed a reinforcing bar frame in which reinforcing bars are connected to each other using a resin band. In the preceding reinforcing bar frame, since it is joined by using a resin band, the labor by welding can be omitted and the assembly can be performed with simple labor. However, in the preceding reinforcing bar frame, the binding portion by the resin band was an intersection where the reinforcing bar materials crossed. Normally, the resin band is bound using a dedicated binding device, but when binding such an intersecting portion of the reinforcing steel material, the winding radius of the binding device reaches the intersection. Therefore, there is a problem that it takes time and effort to set, and the efficiency of the binding operation cannot be improved.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and when reinforcing steel members are bonded to each other with a resin band, they are bonded at a parallel extending portion avoiding an intersection. By this, the resin band can be bound with simple effort,
It is an object of the present invention to provide a rebar frame for a sewer block capable of improving the efficiency of the binding work.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a steel frame for a sewer block according to the present invention (claim 1) comprises:
A reinforcing bar frame buried in a sewer block in which a pipe waterway is surrounded by left and right side walls and upper and lower walls, wherein a main body reinforcing frame buried over the entire left and right side wall and upper and lower walls, and a lower wall and an upper wall. The main reinforcing bar frame has an annular reinforcing bar buried annularly in the width direction of the block, left and right side reinforcing bars extending in the length direction of the block, and The reinforcing bars are integrally framed with a lower reinforcing bar and an upper reinforcing bar. The reinforcing reinforcing bar frame includes a horizontal reinforcing bar extending in the width direction of the block and a vertical reinforcing bar extending in the length direction of the block. Positioning bars extending in the longitudinal direction of the block and embedded in the side walls are integrally attached to the main reinforcing bar frame, and a vertical reinforcing bar connects the reinforcing bar frame to the main reinforcing bar frame. Along with the main reinforcing bar inside the frame, and cross the intersection between the vertical reinforcing bars and the positioning bars. And configured to bind the binder with the resin bands in digit parallel extending portions.

In the rebar frame for a sewer block of the present invention (claim 2), a tubular block portion is formed at both ends of the block, and a lid is provided at a middle portion of the upper wall at a middle portion of the block. Rebar frame embedded in a sewer block in which a U-shaped block portion having an opening for use is formed, a main body rebar frame embedded over the entire left and right side walls and upper and lower walls, and a lower wall and an upper wall A reinforcing bar frame buried in the main body reinforcing bar frame, wherein the main reinforcing bar frame has an annular bar buried annularly in the width direction of the block in the cylindrical block portion, and a U-shape in the width direction of the block in the U-shaped block portion. And a right and left side bar, a lower bar and an upper bar extending and buried in the length direction of the block, and the reinforcing bar frame is formed in the width direction of the block. Reinforcing bars buried to extend in the lengthwise direction of the block Positioning reinforcing bars extending in the length direction of the block and buried in the side walls are integrally attached to the main reinforcing bar frame, and the reinforcing reinforcing bar frame is integrated with the main reinforcing bar frame. The vertical reinforcing bars are set in the main body reinforcing frame along the positioning bars, and the vertical reinforcing bars and the positioning bars are connected by a resin band at a parallel extending portion avoiding the intersection.

In this case, the resin band has a band portion having a large number of locking grooves formed on one surface in a streak shape, and a locking hole formed at a base end of the band portion. The locking claw protrudes from the locking claw, and a locking projection for engaging the locking claw with the locking groove is formed by using a resin band formed facing the locking hole. There is 3).

According to the present invention, in a state in which the reinforcing bar is set in the main reinforcing bar, the vertical reinforcing bars and the positioning bars of the reinforcing bar are joined by a resin band at the parallel extending portion avoiding the intersection. Have been. As described above, since the reinforcing steel members are joined by the resin band at the parallel extending portions avoiding the intersections, the resin band can be joined with simple labor, and the efficiency of the joining operation is improved. can do.

[0009] Further, positioning bars are integrally assembled to the main body reinforcing frame. This positioning bar is used for positioning when the reinforcing bar is set in the main bar frame, and may be used as a side bar of the main bar frame, or may be provided as a separate member from the side bar. Good. By providing the positioning bars, the reinforcing bar can be set at a predetermined position. With this, it is necessary to support the reinforcing bar with a hand or a jig when attaching the resin band. And the binding work becomes easier.

When the resin band is used, it is only necessary to pass the end of the band portion through the locking hole while the band portion is hung 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.
This binding operation is performed using a dedicated binding device (for example, trade name QS-102, AT-2000, manufactured by Tyton Corporation).

A locking projection 54 for engaging with the locking groove 52 is formed facing the locking hole 51. In use, the end of the band portion 50 is passed through the locking hole 51 while the band portion 50 is hung around the rebar material to be joined, and then the band portion 50 is tightened tightly. In this case, the locking hole 51
The locking projection 54 of the locking claw 53 projecting from the
Engages with the locking groove 52 formed on one side of the
Zero loosening is prevented.

As described above, in the rebar frame 2 for culvert blocks, the reinforcing band 4a, 4b is set in the main frame 3, and the resin band 5 is formed in the parallel extending portion avoiding the intersection X. Are joined by a bond.
