Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly type hoop for a reinforcing bar basket used for cast-in-place piles and the like.

[0002]

2. Description of the Related Art As a conventional technique, a hoop reinforcement H is inserted from above a reinforcing bar cage body TH formed by welding a main reinforcement S at a required pitch to an assembly ring R (also referred to as a reinforcing material) provided at required intervals. .. (See FIGS. 13 and 14) Next, one end of the hoop muscle H is moved to the outside of the main muscle S and rotated. (See FIG. 15) Subsequently, the hoop muscle H is wrapped around the outer circumference of the main muscle S. (See FIG. 16) Finally, the hoop muscle H and the main muscle S are zigzag welded Y. (Fig. 1
(See 7)

The above method has the following problems. (1) Only a skilled worker, who is a specialist, can process and assemble the hoop muscles. (2) Welding is always required to fix the hoop muscles and the main muscles. (3) The finished reinforced steel basket is heavy, and the welded part may be damaged due to impact during movement and installation. (4) Since the hoop muscles are attached by welding, the rebar cage is likely to be twisted. (5) Since the processing becomes a specialized contractor and a skilled worker, the cost becomes high.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and its purpose is to reduce the cost because no skill is required for on-site processing, and there is no welding stop so that deformation does not occur and welding is performed. It is intended to provide a prefabricated hoop for a reinforcing bar basket, which is stable in quality without being damaged due to.

[0005]

As means for solving the problems, at least two arcuate hoop bodies are provided with locking portions corresponding to the main bars of each pitch. A locking part should be provided inside the arcuate hoop body. Also, the arc-shaped hoop body must be a deformed steel bar. The arc-shaped hoop body must be a flat plate. In addition, a connecting tool for connecting the arcuate hoop bodies should be provided. Furthermore, the connector is a fixing coupler. The connector has bolts and nuts. It is characterized in that the connector has a supporting portion for supporting the main bar.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION 1 is an assembly type hoop for a reinforcing bar basket, in which an engaging groove 3a made of a flat plate corresponding to the main bar of each pitch is formed inside an arcuate hoop body 2 made of two deformed steel bars. The locking portion 3 is fixedly provided. Further, reference numeral 4 is a connecting member made of a circular tubular fixing coupler that connects the arcuate hoop bodies 2 to each other.

An example of use of the assembly type hoop 1 for the reinforcing bar basket will be described below. The locking groove 3a of the locking portion is attached to each main bar S1 --- from the up and down direction of the pre-assembled rebar cage body TH1.
And attach the assembly type hoop 1.1 for the reinforced steel basket. At this time, the connecting tools 4 are inserted into both ends of the reinforced basket assembly hoop 1 and crimped 4a with a hydraulic crimping machine (not shown).

Next, another embodiment will be described. In the assembly type hoop 21 for a reinforcing bar basket, an arc hoop body 22 made of a flat plate is integrally provided with a locking portion 23 formed by forming a locking groove 23a, and a bolt 24a and a nut 24 are provided at both ends.
A connecting member 24 is provided by b.

The rebar cage assembling hoop 21 is connected by screwing a bolt 24a into a nut 24b.

The connecting member 34 has support members 3 on both sides at the bottom of a fixing coupler 34a having a slit 34a1 formed at the top.
4b1 is formed in a reverse T-shaped support portion 34b.

The connecting member 34 is formed by adjoining main bars S2 and S.
After inserting the support portion 34b between the two, the both ends of the arcuate hoop body 2 are inserted into the fixing coupler 34a and pressure-bonded by a pressure bonding machine (not shown) or the like. In this way, the support piece 34b1
-34b1 can securely support and fix the main bars S2 and S2.

In each of the above embodiments, the reinforced basket assembly type hoop is composed of two arcuate hoop bodies (divided into two), but three or more arc hoop bodies may be used as required. Further, the shape of the locking portion is not limited to the embodiment, but other shapes may be used as long as they have the same function, and the number of locking grooves may be set as necessary. Further, the arc-shaped hoop body may be a deformed steel bar or a flat plate (for example, a round bar). Furthermore, the connector may be in another form as long as it has a similar function.

[0013]

[Effects of the Invention] 1) Since it can be mass-produced in a factory and does not require on-site processing, no skill is required and anyone can easily
It can be installed securely and quickly. 2) Since it can be connected by a connecting tool, welding is not required and a qualified welding person is not required. 3) No deformation occurs because there is no welding stop. 4) By using a fixing coupler as the coupling tool, the coupling can be reliably performed. 5) The connecting tool can be attached with a simple tool by using bolts and nuts. 6) Since it can be firmly attached to the main bar by the supporting portion, the arcuate hoop body is more unlikely to come off.
