Description

  The present invention relates to a reinforcing bar bonding method, a pre-set reinforcing bar, and a reinforcing bar bundling apparatus for bonding reinforcing bars arranged in a lattice at an intersection of the reinforcing bars.

  In reinforced concrete structures, reinforcing bars are embedded in a grid. In this structure, at the time of arrangement of bars to be formed into a grid or placing concrete, the crossing portions of the grid-like reinforcing bars are bound using a wire rod or the like so that the positions of the reinforcing bars do not shift. In addition, fixing using binding agents other than a wire is also performed.

  In addition, a technology has also been studied in which crossing points of reinforcing bars are automatically identified and the binding operation is performed automatically or semi-automatically (for example, see Patent Documents 1 and 2). In the binding machine for rebar mesh described in Patent Document 1, the rolling element is brought into contact with the flat planar notch portion and the notch portion of the rotation holder, and the binding wire is cut and operated by the blade through the swing arm. Further, the gripping body holding the winding binding wire in the gripping hole is rotated by the rotation holder, and is gradually retracted as the load applied to the rotation holder is increased, thereby causing a twist operation under tension. Furthermore, at the time of winding of the binding wire, the rolling element is brought into contact with the flat surface notch of the rotary holder, and the gripping holes formed by the pair of gripping pieces are stopped and held on the winding trajectory of the binding wire. .

  Moreover, the reinforcing bar automatic binding device described in Patent Document 2 is provided with a pair of guide arms which can be moved up and down and which can be opened and closed in a main body which can be moved to any position. Then, a pair of push bars that can slide horizontally is provided at the lower edge of the guide arm, and a rotary body is provided on the center line of the guide arm. Then, a binding wire guide passage leading to the rotating body via the guide arm closed via the rotating body is provided.

  The bundling machine for rebar mesh described in Patent Document 1 performs an operation of twisting and fixing both end portions after the entire two intersecting bars are bridged in a U-shape with a tying line. In addition, the automatic reinforcing bar binding device described in Patent Document 2 performs an operation of twisting and fixing both end portions after winding a plurality of times with a binding wire around the entire two intersecting bars. For this reason, the mechanism of the device is complicated and one binding operation takes time. Moreover, there was little freedom in the operation | movement to fix, and it could not be united unless the position of the rebar intersection part was grasped | ascertained correctly.

  This invention is made in view of the above-mentioned subject, The objective is to provide the reinforcing-bars bundling method, the pre-set reinforcing bars, and the reinforcing-bars bundling apparatus which can perform reinforcing bar binding efficiently.

  The reinforcing bar bundling method, the pre-set reinforcing bar and the reinforcing bar bundling apparatus for solving the above-mentioned problems bind the intersections of the reinforcing bars arranged in a plane. And a binding tool is arrange | positioned so that it may contact | abut with two reinforcing bars which cross | intersect in the said intersection part in the said planar work surface side, Each reinforcing bar which cross | intersects in the said crossing part, The said binding tool, Are bonded by an adhesive material supplied from the work surface side. Thereby, in the intersection part, the 1st rebar and the 2nd rebar can be bound only by the work from the one side (working surface side). Therefore, since it is not necessary to insert a part of apparatus which performs binding to the opposite side of a work surface, time required for one binding operation can be reduced, and binding operation can be performed efficiently. Further, since the binding tool and each reinforcing bar are bonded using an adhesive, if the bonding tool is within the bonding surface where the adhesive spreads, it can be fixed. Therefore, even if the positions of the respective reinforcing bars at the intersections are shifted within the bonding surface, the first and second reinforcing bars can be bound.

  In the reinforcing bar binding method, it is preferable that two reinforcing bars intersecting at the intersection portion be bonded together with the binding tool by the adhesive material. As a result, since the reinforcing bars can be adhered to each other by an adhesive, the first reinforcing bar can be more firmly fixed to the second reinforcing bar with a simple configuration.

  In the reinforcing bar bundling method, it is preferable that the bonding material is formed so as to enter the through hole as the bundling device using a case in which the through hole is formed. As a result, the adhesive also penetrates the through holes, so that the binding tool can be fixed more firmly.

  In the reinforcing bar bundling method, the wire rod constituting the bundling device straddles the first reinforcing bar arranged on the work surface side, and contacts the second reinforcing bar intersecting the first reinforcing bar at the intersection portion. It is preferable to arrange | position and adhere | attach the said 1st rebar and the said 2nd rebar, and the said binder respectively. Thereby, the 1st rebar and the 2nd rebar can be more firmly fixed with a binding tool.

  In the reinforcing bar binding device, the binding tool straddles the first reinforcing bar disposed on the work surface side, and the shape in which both ends are in contact with the second reinforcing bar intersecting the first reinforcing bar at the intersection portion I am Thereby, the 1st rebar and the 2nd rebar can be more firmly fixed with a binding tool.

  According to the present invention, reinforcing bars can be bound efficiently.

As shown in FIG. Then, the first and second reinforcing bars (11, 12) are adhered to the wire with an adhesive. Below, the case where the reinforcement binding device 40 which automated this work is used is demonstrated.

(Bar binding device)
Next, the configuration of the reinforcing bar binding device 40 having the reinforcing bar binding device in which the first reinforcing bar 11 and the second reinforcing bar 12 are bound at each of the intersections 15 of the wall bars 10 will be described using FIG. 2.

The wire connection device 40 includes a wire connection control unit 41, an intersection detection unit 42, a bonding head moving device 45, and a reinforcing wire bonding head 50.
The wire connection control unit 41 controls the binding head moving device 45 and the reinforcing bar binding head 50 in accordance with the signal from the intersection detection unit 42.

The intersection detection unit 42 includes a position sensor or the like, and detects the position of each intersection 15.
The binding head moving device 45 moves the reinforcing bar binding head 50 in a two-dimensional direction (x direction and y direction).

  The reinforcing bar binding head 50 functions as a reinforcing bar binding device, and performs binding at each intersection. The reinforcing bar binding head 50 includes a binding processing control unit 51, a wire placement unit 52, a wire cutting unit 53, a wire forming unit 54, an adhesive discharge unit 55, and a discharge head moving unit 56. In the present embodiment, the wire placement portion 52, the wire cutting portion 53, and the wire formation portion 54 function as a binding placement means, and the adhesive discharge portion 55 and the discharge head moving portion 56 function as a bonding formation means.

  The binding processing control unit 51 controls the binding by the reinforcing bar binding head 50. In the present embodiment, the binding processing control unit 51 controls the disposition of the binding device 20 on the intersection portion 15, the formation of the shape of the binding device 20, and the discharge of the adhesive.

The wire placement portion 52 accommodates a wire, sends a part of the wire onto the intersection 15, and places the wire so as to straddle the first reinforcing bar 11 on the second reinforcing bar 12.

(Bar arrangement process)
Next, with reference to FIG. 3 and FIG. 4, the wire arrangement processing by the wire arrangement device 40 described above will be described. Here, after arranging the second reinforcing bars 12 on the mounting member, the first reinforcing bars 11 are arranged in advance on the second reinforcing bars 12 so as to be orthogonal to the second reinforcing bars 12.

  First, the wire connection control unit 41 of the wire connection device 40 executes moving processing of the reinforcing bar bonding head (step S1). Specifically, the arrangement control unit 41 drives the binding head moving device 45 to move the reinforcing bar binding head 50 in a two-dimensional direction.

Then, the wire bundle binding control unit 41 of the wire tie device 40 performs a process of determining whether or not it is a crossing portion (step S2). Specifically, in response to the detection signal from the position sensor of the intersection detection unit 42, the wire arrangement control unit 41 detects the intersection of the wall muscle 10 placed on the placement member.
Here, when it is determined that it is not a crossing portion (in the case of “NO” in step S2), the rebar / bundling control unit 41 continues the moving process of the reinforcing bar binding head (step S1).

  On the other hand, when it is determined that the crossing portion is the crossing portion based on the detection signal (in the case of “YES” in step S2), the rebar and bundling control unit 41 executes the binding process (step S3). Specifically, the wire connection control unit 41 outputs a movement stop instruction signal to the binding head moving device 45 and outputs an instruction signal to the reinforcing bar binding head 50 so as to perform the binding process.

Then, the binding processing control unit 51 of the reinforcing bar binding head 50 executes a placement processing of the wire (step S3-1). Specifically, the binding processing control unit 51 controls the wire placement unit 52 to send out a part of the wire rod 20 a stored on the detected crossing portion 15.
Here, as shown in FIG. 4A, the wire placement unit 52 sends out the wire 20 a at the intersection 15 so as to straddle the first reinforcing bar 11 and along the second reinforcing bar 12.

  Next, the binding processing control unit 51 of the reinforcing bar binding head 50 executes a forming processing of the wire (step S3-2). Specifically, the binding processing control unit 51 controls the wire placement unit 52 and the wire forming unit 54 to form the wire 20a.

  Here, as shown in FIG. 4 (b), the wire rod forming unit 54 deforms the pair of pressing members 54 a by pressing the wire rod 20 a against the second reinforcing bar 12 at positions on both sides of the first reinforcing bar 11. As a result, the linear wire 20 a is formed into a substantially inverted U-shape that straddles the first reinforcing bar 11.

  Next, the binding processing control unit 51 of the reinforcing bar binding head 50 executes an adhesive discharge processing (step S3-3). Specifically, the binding processing control unit 51 controls the adhesive discharge unit 55 and the discharge head moving unit 56 to discharge the adhesive onto the wire 20 a disposed on the first reinforcing bar 11 and the second reinforcing bar 12. Do.

  Here, as shown in FIG. 4C, the discharge head moving unit 56 moves the nozzle 55 a of the adhesive discharge unit 55 onto the wire 20 a at the central position of the first reinforcing bar 11. Then, the adhesive discharge unit 55 discharges the adhesive from the nozzle 55 a to form the bonding member 21. Furthermore, the discharge head moving unit 56 moves the nozzle 55a to the contact position between the second reinforcing bar 12 and the wire 20a. Then, the adhesive discharge unit 55 discharges the adhesive from the nozzle 55 a in an amount such that spot adhesion is achieved, and forms the adhesive member 22.

Then, the binding processing control unit 51 of the reinforcing bar binding head 50 executes the cutting processing of the wire rod (step S3-4). Specifically, the binding processing control unit 51 cuts between the bonding member 22 on the wire placement unit 52 side and the wire placement unit 52 using a cutting tool.
Here, as shown in FIG. 4 (d), the first reinforcing bar 11 and the second reinforcing bar 12 are bound by the binding tool 20.

  When the binding process is completed, the binding process control unit 51 transmits a binding process end signal to the wire connection control unit 41.

  Then, the wire connection control unit 41 executes a determination process as to whether or not all the bonds are completed (step S4). Here, in the wall 10, when there are other crossing portions 15 that are not bound (in the case of "NO" in step S4), the rebar binding control unit 41 performs the rebar binding head movement process (step S1) Execute the process of

On the other hand, in the case of the wall muscle 10, when there is no crossing portion which is not bound (in the case of "YES" in step S4), the wire connection control part 41 ends the wire connection process.
According to the reinforcing bar binding method, the pre-set reinforcing bar, and the reinforcing bar binding device of the present embodiment, the following effects can be obtained.

  (1) The crossing portion 15 between the first reinforcing bar 11 and the second reinforcing bar 12 of the wall reinforcement 10 of the present embodiment is bundled using a linear tie 20. The binding tool 20 is disposed on the work surface (upper surface) side. The binding tool 20 is bonded to the first reinforcing bar 11 via the bonding member 21, and is bonded to the upper side (working surface side) of the second reinforcing bar 12 via the bonding member 22. Thereby, in the intersection part 15, the 1st rebar 11 and the 2nd rebar 12 can be bound by the operation from the upper side (one side) of the surface comprised from the 1st rebar 11 and the 2nd rebar 12 . Therefore, it is possible to reduce the time required for the binding operation and to improve the efficiency of the binding operation. Further, since the binder 20 and the respective reinforcing bars (11, 12) are bonded using an adhesive, if the binder 20 is present in the bonding surface in which the adhesive is spread, it can be fixed. Therefore, even if the positions of the first reinforcing bar 11 and the second reinforcing bar 12 at the intersection portion 15 are shifted in the range within the bonding surface, the first reinforcing bar 11 and the second reinforcing bar 12 can be bound.

  (2) In the present embodiment, the central portion of the binder 20 has a convex shape of a size straddling the first reinforcing bar 11, and is bonded to the second reinforcing bar 12 at both end portions of the binder 20. Thereby, the 1st rebar 11 can be more firmly fixed with the binding tool 20.

  (3) In the present embodiment, the binding member 20 and the bonding member 22 for bonding the second reinforcing bar 12 are bonded by point bonding. Thereby, when the bending force is applied to the second reinforcing bar 12, the spread of the adhesive surface which is easily peeled can be suppressed, so that the adhesion between the binder 20 and the second reinforcing bar 12 can be hardly peeled off.

In this case, the binding processing control unit 51 of the reinforcing bar binding head 50 drives the adhesive discharge unit 55 and the discharge head moving unit 56 in the discharge processing of the adhesive (step S3-3) in the wire repositioning processing. The bonding member 27 is formed to bond the first reinforcing bar 11, the second reinforcing bar 12 and the wire 20a.

According to this embodiment, in addition to the effects of the above (1) and (2), the following effects can be obtained.
