Description

Automatic rebar arrangement apparatus for XY rebar grid manufacturing for square column reinforcement

The present invention is for rectangular column reinforcing bars capable of automatically arranging a plurality of main bars at regular intervals in order to manufacture an XY reinforcing bar grid network composed of a plurality of spaced bars connecting a plurality of main bars arranged in parallel at regular intervals to each other at regular intervals. It relates to an automatic rebar arrangement device for manufacturing XY rebar grid mesh.

Among the architectural and civil engineering technologies, one of the reinforced concrete technologies, the rebar line assembly technology, is the slowest technology to advance.

Recently, automatic rebar grid manufacturing facilities capable of manufacturing rebar grids in an automated way have been developed in developed countries in Europe and are being distributed around the world. As a result, there is a shortage of skilled workers and an aging phenomenon, and construction sites are experiencing many difficulties.

Fortunately, the field of applying rebar line assembly using full XY rebar grids, XY rebar grids, and XY rebar grids with spacing bars for reinforcement for foundation floors, slabs, walls, etc. is rapidly increasing. .

In addition, CIP for basement retaining pile construction, PRD and RCD for pile construction for structures, and round-shaped pile structures such as piers are being actively assembled through factory production through coil rebar production by domestic steelmakers.

However, the reinforcing bar of the square column rebar assembly is still assembled in a conventional way that relies on manpower at the site, not befitting the high-rise and large-scale construction of civil engineering structures.

In other words, in a state where all the main bars of each strand are erected according to the design quantity, the closed hoop reinforcing bars inserted in the lower part are raised upwards, and then repeatedly tied at regular intervals along the longitudinal direction of the main bars, and then deep restraint, which is a reinforcing bar for shear. By assembling and binding anchor reinforcing bars, a square column reinforcing bar assembly is completed.

Here, the reason that the square column rebar assembly cannot be manufactured in an automated way is because the size of the square column, the size of the reinforcing bars, and the quantity are not standardized by the structural calculation, but are designed in various ways according to the number of floors, the scale, and the purpose of the building.

That is, since only the standard and quantity of the main bars constituting the rectangular column reinforcing bar assembly are regulated, the spacing of the main bars is not constant, making it impossible to pre-assemble in an automated manner.

And in the case of a low-rise building with a low four-story height, the standard of the square column rebar assembly is not large and the number of main bars is small. As the length of the lap splicing is added to the length, even the single main reinforcing bars are heavy, so they must be erected vertically to bind or fasten with the main bar of the lower-layer rectangular column reinforcing bar assembly where the lapped splices are exposed so that they do not fall over. The physical fatigue of people increases and the risk of safety accidents is inevitably high.

Therefore, in order to respond to the shortage of manpower and aging, to solve the risk of safety accidents, and to protect the safety of workers, it is necessary to research and develop a technology that can manufacture medium-to-large rectangular pole rebar assemblies in a safer and more effective way than the conventional method. do.

Hereinafter, an automatic reinforcing bar arrangement apparatus for manufacturing an XY reinforcing bar grid for square column reinforcing bars according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The automatic reinforcing bar arrangement apparatus 100 for manufacturing an XY reinforcing bar grid for square column reinforcing bars according to a preferred embodiment of the present invention is shown in FIG. Used when arranging the main bars (M) separated and supplied one by one at a predetermined interval in the left and right directions in the step-by-step main bar separation device (not shown) disposed at the front end for the manufacture of the XY reinforcing bar grid network (G) shown in Fig. As shown in FIGS. 2 and 4, the support frame 10, the slide ramp 20, the spacing adjusting bar 30, the main fall guide bar 40, the stopper 50, the detection sensor (not shown) and a controller (not shown).

First, the support frame 10 may be provided with an upper surface that is seated on the floor and gradually decreases in height from right to left.

That is, a plurality of support frames 10 are spaced apart from each other in the front and rear and left and right directions, the lower part is seated on the floor, and the upper part is lowered in height from right to left depending on the installation position. It may be composed of a connecting reinforcing bar 12 for reinforcing and supporting the horizontally connecting between the posts 11 .

Next, a plurality of the slide ramp 20 may be installed on the upper portion of the support frame 10 in the left and right directions at a predetermined distance from each other in the front and rear directions.

That is, the slide ramp 20 may be installed to be inclined downwardly from the right to the left according to the height of each installation position of the support stand 11 .

And the guide rail 21 may be installed on the upper portion of the slide slope 20 . In addition, the separation prevention block 22 for limiting the guide path of the guide rail 21 may be installed at the left end and the right end of the slide ramp 20, respectively.

Next, a plurality of the spacing adjusting bar 30 may be installed in parallel to each other in the front-rear direction on the upper portion of the slide ramp 20 .

In addition, the interval adjusting bar 30 is engaged with the guide rail 21 at the lower portion so as to be movable in the left and right directions on the slide ramp 20, and the moving block 31 sliding along the guide rail 21 is installed. Thus, the distance between each other along the left and right directions can be manually adjusted.

In addition, a rotation shaft 32 for performing a rotation operation of the stopper 50 may be rotatably installed on the upper portion of the spacer 30 .

Next, the main root drop guide bar 40 may be installed parallel to each other at a predetermined distance on the upper portion of the spacing adjusting bar 30 .

That is, the main root drop guide bar 40 can guide the main bars M, which are separated and supplied one by one through the stepped separation device from the right side, to fall downward in the left direction along the upper surface.

To this end, the main muscle drop guide bar 40 may be installed to be spaced apart from the floor by a predetermined distance by a pair of support legs 41 having different heights.

And the main root drop guide bar 40 may be formed so that the lower right end and the lower left end are connected to the upper end of each support leg 41 so that the upper surface is inclined downward from the right to the left due to the height difference of the support leg 41 .

However, the main root fall guide bar 40 has a plurality of main roots M to guide the fall stably while rolling on the upper surface of the main muscle drop guide bar 40 due to acceleration. It can be installed to have an inclination angle of 6° larger than 8°, which is less likely to deviate from 7° and has a high possibility that the main bar (M) may not fall properly by the reinforcing bar ribs due to insufficient acceleration.

Next, a plurality of the stoppers 50 are installed at regular intervals on the interval adjusting bar 30 and operate sequentially according to a control signal input from the outside to protrude higher than the upper surface of the main drop guide bar 40 . can

That is, the stopper 50 sequentially stops a plurality of main roots (M) falling from the right to the left downward on the upper surface of the main root drop guide bar 40 to be arranged to be spaced apart from each other by the interval according to the stopped position. can

To this end, the stopper 50 may include a connection bracket 51 , a driving cylinder 52 , a connection piece 53 , a main rotation piece 54 , and an auxiliary rotation piece 55 .

The connection bracket 51 may be fixedly installed at the end of the spacing adjusting bar 30 .

The driving cylinder 52 may be rotatably connected to the connecting bracket 51 .

The connecting piece 53 may be rotatably installed on the rod of the driving cylinder 52 .

The pivoting piece 54 is rotatably fixed at its center to the end of the pivoting shaft 32 and rotatably connected to the connecting piece 53 at the lower end, and the main locking end 54a at the upper portion is bent upward. As shown in FIG. 5, the end of the main locking end 54a protrudes further to the upper portion of the spacing adjusting bar 30 while rotating along with the rotation shaft 32 according to the operation of the driving cylinder 52 to stop the main root (M). function can be performed.

A plurality of the auxiliary rotation pieces 55 are integrally rotatably connected to the rotation shaft 32 at regular intervals, and the auxiliary locking end 55a corresponding to the main stopping end 54a is bent upward at the upper portion. It can perform a function of stopping the main muscle (M) by the auxiliary locking end (55a) while rotating with the main rotating piece (54).

Here, the stopper 50 can adjust the plurality of main rods M to correspond to the spacing of the spacer 30 as each is connected to the spacer 30 .

That is, when the user adjusts the left and right positions of the spacing bars 30 in order to arrange the plurality of main bars at a predetermined interval and adjusts them to the same intervals as the predetermined intervals, the plurality of main bars M is adjusted to the spacing of the spacing bars 30 . It can be easily arranged at a correspondingly determined interval.

On the other hand, the stopper 50 eliminates the operational interference between the main rotational pieces 54 and the auxiliary rotational pieces 55 adjacent to each other along the left and right directions in the spacer 30, thereby reducing the spacing of the spacer 30. It can be adjusted as narrow as possible.

To this end, the connecting bracket 51, the driving cylinder 52, the connecting piece 53, and the main rotating piece 54 are respectively the odd-numbered spacer 30 and the rotating shaft 32 in the order from the left to the right. It may be installed at the front end and at the rear end of the even-numbered spacer 30 and the rotation shaft 32 in the order from left to right.

And the auxiliary rotation piece 55 installed on the rotation shaft 32 located at odd-numbered positions in the order from left to right and the auxiliary rotation piece 55 installed on the rotation shaft 30 located at even-numbered positions in the order from left to right direction. The front and rear positions may be different and may be installed to be spaced apart from each other.

That is, as the positions of the main rotating piece 54 and the auxiliary rotating piece 55 adjacent to each other along the left and right directions are installed with a position difference in front and rear so as not to interfere with each other, the main rotating piece 54 and the main rotating piece 54 during operation of the driving cylinder 53 Since the rotation radius of the auxiliary rotation piece 55 does not overlap with each other, it is possible to completely exclude the operation interference between each other.

Therefore, even if the distance between the stoppers 50 is adjusted as narrow as possible by adjusting the spacing of the spacing bars 30 as narrow as possible, it does not cause an inoperable state due to operational interference between the stoppers 50, so that the main bars M are spaced more closely. can be arranged as

Next, the detection sensor is provided in the step separation device to individually detect a plurality of main roots (M) separately supplied one by one in the step separation device, generate a detection signal with a time difference and sequentially output it to the outside have.

Finally, the controller sequentially receives the detection signals output to the outside as each of the plurality of main roots M is individually detected by the detection sensor, and generates a control signal corresponding to the detection signal with a time difference so that the stopper 50 is Control signals may be input to the driving cylinders 53 of each stopper 50 to sequentially operate.
