Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a reed-type fixing braided bar in which a plurality of U-shaped rebars are connected by an annealed iron wire, and a stack-type fixing roll formed by stacking the rebar-shaped rebar The present invention relates to a method for manufacturing a braided rebar and a method for constructing a roll-shaped curled rebar that is wound around a plurality of rings and a laminated or rolled braided bar for anchoring.

[0002]

2. Description of the Related Art A roll type slack type braided rebar and a braided type anchoring rebar have been developed and proposed (Japanese Patent Laid-Open No. 2001-20.
0613 publication). This roll-shaped slab type rebar is made up of a large number of rebars that have been arranged in parallel at a certain fixed interval in a factory, etc., sequentially connected by a plurality of flexible strips to form a slab type rebar, which is the core. It is wound around the material and manufactured into a roll. Further, the slack type fixing braided rebar is manufactured in a sloping shape by sequentially connecting a plurality of relatively short rebars arranged in parallel at a predetermined constant interval in advance in a factory or the like with a flexible strip. The roll-shaped sudare type braided bar is carried on a plurality of spacer rows and unrolled and unfolded to be spread as a sudare type braided bar. Will be placed. Also,
The sudare fixing bracing rebar has a structure in which it is inserted between the existing rebar and the rebar to be fixed and is connected to the rebar to be fixed and fixed.

[0003]

The conventional roll-shaped slack type braided rebar is manufactured in advance in a relatively lightweight and compact roll shape at a factory or the like, and is stored, transported before construction, or installed on a construction site (base). It is easy to carry in, for example, unwinding and unfolding on the spacer row, removing the core material and spreading it as a slack type assembled rebar Although the workability and reliability are remarkably enhanced, it is difficult to insert the end portions of the reinforcing bars into the existing reinforcing bars such as beams with only the above-mentioned spreading, and it is necessary to use the reinforcing bar fixing braces together. In addition, in the conventional slack-type anchoring rebar, variations are likely to occur in the inclination of each anchoring rebar and insertion into the existing reinforcing bar, and it takes time and effort to eliminate this variation. There is a problem in improving workability and reliability as well as workability at the construction site, such as the need for laborious site work in which the individual reinforcing bars are individually connected.

The present invention was developed in order to solve the above-mentioned problems, and the object of the present invention is to form a slack type fixing in which the central portions of a large number of U-shaped reinforcing bars are connected by smoothed iron wires. Manufacturing method of the braided rebar for use and the braided type rebar for fixing in a laminated or roll form, and the roll-shaped braided braided bar that is wound by winding a plurality of rings onto the braided type rebar It is to provide a construction method of a braided fixing braided bar.

[0005]

Means for Solving the Problems The braided fixing braided reinforcing bar of the present invention uses a plurality of U-shaped reinforcing bars formed to have a width size corresponding to the reinforcing bar spacing of the reinforcing bars to be fixed. By providing a separation distance in which two or one reinforcing bars to be fixed are arranged between each other, and by sequentially connecting the central portions of the legs of each U-shaped reinforcing bar with an excellent flexible smoothed iron wire, When inserted between the existing reinforcement and the tip of the reinforcement,
The tips of both legs of the U-shaped rebar are easily and properly inserted into the existing bar arrangement, and each U-shaped rebar is aligned without any particular variation between the tips of the rebars to be anchored. Each U-shaped rebar is placed precisely every other or each rebar interval, and each U-shaped rebar is connected to the rebar to be anchored. Easy and easy on-site anchoring work allows quick and accurate construction. In addition to the workability at the construction site, the workability and reliability are significantly improved.

Further, the above-mentioned slack-type fixing braided bar is manufactured in a factory or the like, and is easily folded or rolled up due to the excellent flexibility of the annealed iron wire to be a lightweight and compact laminated or roll shape. It is manufactured in the sudare type anchoring rebar, and it is easily transported and stored before construction and carried in to the construction site, and it is easily rolled out at the construction site for construction. Work is done efficiently and accurately.

[0007] Further, as a slack type braided rebar in which a large number of rebars are provided at regular intervals and are sequentially welded with a plurality of flexible flat steel strips, the bar is wound around a plurality of rings to be manufactured. By rolling the rolled sudare type braided rebar close to the existing rebar, unrolling it and expanding it to spread it as a bundle type braided rebar, each rebar of the braided type braided rebar is fixed at predetermined intervals as the reinforcing bars to be anchored. Precisely and easily constructed, between each rebar tip of this sudare type rebar and the existing bar arrangement,
When the above-mentioned laminated or roll type braided reinforcing bar for reinforcement is unrolled and inserted as a braided type braided bar for fixing, each leg end side of each U-shaped rebar of the braided type braided reinforcing bar easily fits within the existing bar arrangement. The U-shaped rebars are properly inserted into the legs, and the base ends of both legs of the U-shaped rebars are aligned with each other without any particular arrangement variation between the tips of the rebars to be anchored (rebars of the braided rebar). Each U-shaped rebar is placed precisely every other space or each rebar, and each U-shaped rebar is connected to the rebar to be anchored. Easy and easy construction work is performed by fixing work at the construction site. As a result, workability at the construction site as well as workability and reliability are significantly improved.

The above-mentioned slack type anchoring braid is constructed between various existing bar arrangements and the tips of various anchoring rebars arranged at regular intervals. In the case of a small scale, it is laminated or It is also possible to carry it into the construction site without forming it into a roll shape and omit the step of unrolling, and to carry out construction, and basically the same actions and effects as described above can be obtained.

[0012] The above-mentioned slack type anchoring rebar and its laminated or roll type slag type anchoring rebar are used for various concrete structures (RC construction, S construction, etc.) in various constructions, civil engineering, concrete paved roads and the like. When SRC construction etc.) is constructed, it is effectively applied as a concrete reinforcing bar arranged and fixed between various existing reinforcing bars and various fixing target reinforcing bars arranged at regular intervals.
