Description

{Multi-tsteel wire inserting apparatus}

The present invention relates to a multi-steel wire inserting device for reinforcing a structure, in which when tensile steel wire is installed inside a structure in order to prevent deflection deformation and cracking due to a continuous load at the time of construction of various concrete structures, And more particularly, to a multi-steel wire inserting device for reinforcing a structure for supplying a steel wire to the inside.

In general, when constructing various concrete structures such as roofs of concrete bridges, a large amount of reinforcing bars are placed inside the structure to prevent the concrete structures from being easily broken when wind, vibration, or earthquake occurs. A tensile steel wire is provided as a means for preventing the generation of cracks due to the deflection deformation and for reinforcing it more safely.

That is, after curing so as to form a plurality of hollow holes in the structure, steel wires having a high tensile strength are forcedly inserted.

Since such a steel wire is usually made by twisting a plurality of wires, it is necessary to provide a device capable of automatically feeding the steel wire because the wire is considerably large in diameter and heavy for a worker to manually work. As such technology, No. 0648638 (Steel wire inserting machine) and Patent Registration No. 10-0542154 (Steel wire inserter) have been proposed.

The steel wire inserter having such a configuration can insert the steel wire into the insertion object by driving the drive roller after bringing the draw-out side steel wire guide mechanism of the steel wire inserter close to the insertion object by using the traveling mechanism, There is a problem that the working time is delayed and the efficiency is lowered.

Patent Document 1. Patent Registration No. 10-0648638 (November 15, 2006) 2. Patent Registration No. 10-0542154 (2006.03.03)

The present invention provides a multi-steel wire inserting device for reinforcing a structure, which can insert a plurality of steel wires into a structure by a single operation.

The present invention also provides a multi-steel wire inserting device for reinforcing a structure, which is easy to move and can cope with according to a position of inserting a steel wire by being mounted on a car having a lift device.

The apparatus for inserting multi-steel wire according to the present invention is characterized in that a fixing body 20 is installed on a table 10 and a driving shaft 30 and a driven shaft 30a are installed on the fixing body 20 up and down, A driving motor 34 is connected to the driving shaft 30 and a driving roller 32 and a guide roller 32a for feeding the steel wire while being meshed with the driving shaft 30 and the driven shaft 30a are arranged in one or more rows A supply unit 100; Below the table 10 there is a lower frame 12 with a wheel 18 and an upper frame 11 connected by an upper link 14a is vertically operated by a drive cylinder 40 200).

According to the present invention, since one or more steel wires are simultaneously inserted into a plurality of steel wire insertion holes formed in a structure by a single operation, it is possible to reduce the cost due to the reduction of the working time and the number of the workforce, It is easy to control and the operation efficiency can be greatly increased.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of an apparatus for inserting a multi-steel wire for reinforcing structures according to a preferred embodiment of the present invention; FIG.
FIG. 2 is a partial view showing a side view of a multi-steel wire inserting structure for reinforcing structures according to a preferred embodiment of the present invention. FIG.

Best Mode for Carrying Out the Invention Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Like reference numerals can be used for similar elements in connection with the description of the drawings.

The apparatus for inserting multi-steel wire according to the embodiment of the present invention is characterized in that a fixing body 20 is mounted on a table 10 and a driving shaft 30 and a driven shaft 30a are connected to the fixing body 20, A drive motor 34 is connected to the drive shaft 30 and a drive roller 32 and a guide roller 32a for transmitting the steel wire while being meshed with the drive shaft 30 and the driven shaft 30a are connected to one or more A feeder (100) arranged in multiple rows;

Below the table 10 there is a lower frame 12 with a wheel 18 and an upper frame 11 connected by an upper link 14a is vertically operated by a drive cylinder 40 200).

A tensioner (24) for adjusting the tension of the driven shaft (30a) is mounted on the fixed body (20).

In addition, the lifting device 200 is provided with a support rod 50 that can be fixed to the ground surface by rotation.

The above is explained in more detail as follows.

FIG. 1 is a top view of a supply part 100 and a lower part 200 of a multi-steel wire inserting device for reinforcing a structure according to the present invention. And a lifting device 200 capable of moving the supply part to an appropriate position and adjusting the height thereof.

The feeder 100 is provided with a fixing body 20 on the table 10 and the bearing housing 26 is mounted on both sides of the fixing body so as to be parallel to the upper and lower sides and the driving shaft 30 and the driven shaft 30a ) Is installed.

A drive motor 34 having a predetermined reduction gear is connected to the drive shaft 30. The drive shaft 30 and the driven shaft 30a are engaged with a semicircular cross section along the circumference The driving roller 32 and the guide roller 32a into which the steel wire 1 is inserted are mounted.

At this time, the driving roller 32 and the guide rollers 32a are arranged in a plurality of rows and are capable of supplying one or more steel wires 1 at the same time. The spacing between the rollers is dependent on the position of the steel wire- It is desirable that the composition can be easily controlled.

A tensioner 24 is provided at the upper portion of the fixing body 20 and is formed of a screw thread so as to vertically transfer the bearing housing 26 supporting the driven shaft 30a so that the pressure input of the steel wire can be controlled do.

2, the guide tube 28 is mounted on the front and rear sides of the fixture 20 to support the steel wire 1 passing between the drive roller and the guide roller.

Next, an elevating device 200 capable of transporting the above-described supply part 100 with a wheel 18 and a handle 19 is provided under the table 10.

The elevating device 200 includes an upper frame 11 for fixing the table 10 of the supplying part 100 and a lower frame 12 for mounting the wheels 18 at the lower part. Quot; X "-shaped around the center fixing pin 15 is connected between the upper frame 11 and the lower frame 12, As the rectangular guide holes 16 are formed in the upper and lower frames, the upper frame 11 moves up and down when the links are folded.
