Description

Manufacturing device and manufacturing method of reinforcing steel rings for CIP

[0001] The present invention relates to a manufacturing device and a manufacturing method of a CIP reinforcing bar ring, and more particularly, to a manufacturing device and a manufacturing method of a CIP reinforcing bar ring, which allows for more quickly binding of coil reinforcing bars by pushing in coil reinforcing bars to be bound while placing reinforcing bars on a reinforcing bar support piston of a jig, and which reduces worker fatigue and improves work efficiency by supporting reinforcing bars and coil reinforcing bars by reinforcing bar support pistons that move back and forth.

[0002] In the field of architectural and civil engineering, which boasts a long history, the field with the slowest pace of progress is the field of reinforced concrete, specifically the field of prefabrication of reinforced concrete.

[0003] This is because the field of rebar prefabrication technology relies heavily on manual labor, as heavy rebars must be processed and arranged to match a predetermined structure and shape, and then the rebars must be tied or welded together to ensure that the processed and arranged shape is maintained until construction is completed.

[0004] Recently, automatic manufacturing equipment for circular reinforcing bar cages for Reverse Circulation Drill (RCD), Percussing Rotary Drill (PRD), and RCD, which manufactures large diameter circular reinforcing bar cages with a diameter of 800 mm or more used in bridge piers, has been developed and distributed, and at the same time, as domestic steelmakers produce coil reinforcing bars, the field of reinforcing bar prefabrication technology through factory manufacturing is gradually advancing, which is greatly contributing to shortening the construction period and improving quality.

[0005] Here, the automatic manufacturing device for a circular reinforcing bar cage for RCD is composed of a reinforcing bar supplying unit that supplies a plurality of reinforcing bars, a reinforcing bar arrangement unit that arranges a plurality of reinforcing bars in a circular shape through a plurality of radially arranged array wings, a fixed rotating unit that supports the ends of a plurality of reinforcing bars arranged in a circular shape by penetrating through them, a moving rotating unit that fixes and rotates the ends of a plurality of reinforcing bars arranged in a circular shape and moves them forward, a hoop reinforcing bar supplying unit that supplies hoop reinforcing bars, a welding unit that welds hoop reinforcing bars to the outer surfaces of a plurality of reinforcing bars being moved forward so that they are spirally wound, and a support unit that supports a plurality of reinforcing bars on the outer surfaces of which hoop reinforcing bars are spirally welded.

[0006] Meanwhile, with the rapid and simultaneous construction of high-rise apartment complexes and large-scale buildings across the country, safety is becoming a top priority, strengthening quality and shortening construction periods.

[0007] As the number of underground floors increases in proportion to the trend toward higher-rise and larger buildings, the collapse of retaining walls during underground excavation work is occurring frequently, leading to an increase in casualties. As a result, design reviews are now mandatory.

[0008] In particular, since the Cast In Place prepacked pile (CIP) method, which is the most representative method among the earth retaining methods essential for temporary facilities in underground excavation work, has not been developed to automatically manufacture small-diameter circular rebar cages with an array diameter of 350 mm or less, most of them are manufactured manually by on-site personnel.

[0009] In the past, there were some inconveniences due to the use of small rebars with a diameter of 22 mm or less for the main bars of the circular rebar cages for CIP, but it was possible to manufacture the circular rebar cages for CIP using the automatic manufacturing equipment for the circular rebar cages for RCD.

[0010] Recently, the number of casualties due to repeated collapses of earth retaining structures has increased, and as the number of underground floors has increased due to the increase in the number of high-rise and large-scale buildings, the number of deep-depth excavation sites has increased explosively.

[0011] Accordingly, as the safety factor based on structural calculations for deep depths increases, large reinforcing bars with a diameter of 32 mm or 35 mm are being applied to the main reinforcing bars of circular reinforcing cages for CIP. However, there are significant problems in manufacturing circular reinforcing cages for CIP with main reinforcing bars of such large sizes using automatic manufacturing equipment for circular reinforcing cages for RCD.

[0012]

[0013] Figure 1 is an exploded three-dimensional drawing showing the state before tying a reinforcing ring made of conventional reinforcing bars and coil reinforcing bars.

[0014] Fig. 1 shows a conventional method for manufacturing a reinforcing bar ring for CIP, in which jigs (10) are arranged at regular intervals and a plurality of reinforcing bars are placed on the jig (10). At this time, six reinforcing bars (11) are usually placed on the jig (10), and the six reinforcing bars (11) are tied to the inner upper, middle, and lower heights of the coil reinforcing bar (12) at intervals, respectively.

[0015] Meanwhile, as shown in Fig. 1, a plurality of reinforcing bars (11) are placed on a jig (10) and a coil reinforcing bar (12) formed in a coil shape is inserted. In order for the coil reinforcing bar (12) to penetrate the jig (10), the coil reinforcing bar (12) is pushed in while rotating.

[0016] That is, the worker must continuously rotate the coil rebar (12) so that it can penetrate the jig (10).

[0017] Accordingly, the worker has to push the coil rebar (12) while rotating it so that it can pass through the jig (10), which takes a long time to work, and as the heavy coil rebar (12) is moved while rotating it, it puts a strain on the worker's musculoskeletal system, and the worker's fatigue increases, which reduces work efficiency.

[0018] In addition, six reinforcing bars are tied to the coil reinforcing bar (12), and since the reinforcing bar (11), which is a heavy object, is tied while being lifted to the upper and middle height of the coil reinforcing bar (12), there are problems such as a decrease in work efficiency and an increase in worker fatigue.

[0019]

[0020] For example, the following patent document 1 discloses an 'automatic manufacturing device for circular reinforcing bar cages for CIP'.

[0021] The automatic manufacturing device for a circular reinforcing bar cage for CIP according to the following patent document 1 is for manufacturing a circular reinforcing bar cage for CIP having a shape in which hoop reinforcing bars are spirally wound on the outer surfaces of a plurality of main bars, and comprises: a first supply unit for supplying the plurality of main bars by lowering them one by one through a stopper; a circular arrangement unit provided on one side of the first supply unit for arranging the plurality of main bars supplied from the first supply unit in a circular shape; a fixed rotation unit provided in front of the circular arrangement unit for supporting and rotating the ends of the main bars by passing them through the circular arrangement unit in a circular shape so that the plurality of main bars are arranged in a circular shape in the circular arrangement unit; a moving rotation unit provided in front of the fixed rotation unit for fixing the ends of the plurality of main bars arranged in a circular shape by the circular arrangement unit and the fixed rotation unit and rotating them while moving them forward; a second supply unit provided on one side of the fixed rotation unit for supplying the hoop reinforcing bars to the outer surfaces of the plurality of main bars while rotating forward by the moving rotation unit; and a second supply unit for supplying the hoop reinforcing bars to the outer surfaces of the plurality of main bars while rotating forward by the moving rotation unit, and wherein the hoop reinforcing bars are arranged in the It includes a welded portion that welds the intersection of the plurality of main bars and the hoop reinforcement so that the plurality of main bars are spirally wound on the outer surfaces of the main bars.

[0022] The diameter of the circular arrangement of the main bars arranged by the circular arrangement part, the diameter of the circular arrangement of the main bars supported by the fixed rotation part, and the diameter of the circular arrangement of the main bars fixed by the movable rotation part are all configured to be the same, so that when a worker moves the main bars forward to arrange the plurality of main bars in a circle, they can move in a straight line without bending.

[0023]

[0070] Accordingly, the reinforcing bar support piston (142) of the first reinforcing bar jig (130) is installed higher than the reinforcing bar support piston (142) of the second reinforcing bar jig (150).

[0071] Meanwhile, in FIG. 3, a first reinforcing bar jig (130) composed of three jig bodies (131 to 133) and a second reinforcing bar jig (150) composed of three jig bodies (151 to 153) are illustrated, but it is to be understood that the jig bodies of the reinforcing bar jigs (130, 150) may be increased or decreased as needed.

[0072] As shown in Fig. 4, a ground support (134) is installed on the lower part of the first reinforcing jig (130) and the second reinforcing jig (150) to be placed on the floor surface, and a lower support (135) is fixed to the upper surface of the ground support (134).

[0098] Figure 12 is a process diagram illustrating a manufacturing process of a reinforcing ring for CIP according to a preferred embodiment of the present invention.

[0099] As shown in Fig. 12, the manufacturing process of the reinforcing bar ring for CIP includes (a) a step (S10) of placing a plurality of reinforcing bars on a reinforcing bar support jig (110), (b) a step (S20) of placing the horizontal reinforcing bars (11) placed on the reinforcing bar support jig (110) on the reinforcing bar support piston (142) moved forward of the first reinforcing bar jig (130) and the second reinforcing bar jig (150), (c) a step (S30) of pushing the coil reinforcing bars (12) toward the horizontal reinforcing bars (11) so that the coil reinforcing bars (12) can be tied to the horizontal reinforcing bars (11) placed on the reinforcing bar support piston (142), and (d) a step (S30) of temporarily tying the horizontal reinforcing bars (11) and the coil reinforcing bars (12) by a tie line (15) to form a reinforcing bar ring unit (170). It includes a step (S40) and a step (S50) of binding the horizontal reinforcing bar (11) and the coil reinforcing bar (12) while placing the bonded reinforcing bar ring unit (170) on a lift.

[0100] As shown in FIGS. 2 to 12, six horizontal reinforcing bars (11) to be tied to coil reinforcing bars (12) are placed on the reinforcing bar stacking frame (115) of the reinforcing bar support jig (110) (S10).

[0101] The above six horizontal reinforcing bars (11) are moved to the reinforcing bar support piston (142) protruding forward of the first reinforcing bar jig (130) (S20).

[0102] With the above six horizontal reinforcing bars (11) placed on the reinforcing bar support piston (142), the coil reinforcing bar (12) is pushed in (S30).

[0103] At this time, the reinforcing bar support piston (142) of the reinforcing bar jig (130, 150) moves backward sequentially, and when the insertion of the coil reinforcing bar (12) is completed, the reinforcing bar support piston (142) moves forward to support the horizontal reinforcing bar (11).

[0104] That is, when the first and fourth jig bodies (131, 151) retreat and the coiled reinforcing bar (12) passes the first and fourth jig bodies (131, 151), the reinforcing bar support pistons (142) of the second and fifth jig bodies (132, 152) retreat and the reinforcing bar support pistons (142) of the first and fourth jig bodies (131, 151) advance to support the horizontal reinforcing bar (11).

[0105] When the coil rebar (12) passes the second and fifth jig bodies (132, 152), the rebar support pistons (142) of the second and fifth jig bodies (132, 152) advance to support the horizontal rebar (11), and the rebar support pistons (142) of the third and sixth jig bodies (133, 153) retreat, and when the coil rebar (12) passes the third and sixth jig bodies (133, 153), the rebar support pistons (142) advance to support the horizontal rebar (11).

[0106] In the step (d), the method includes a first tying step (S42) of tying the coil reinforcement (12) and two horizontal reinforcements (11) while positioning the two horizontal reinforcements (11) on the inner upper side of the coil reinforcement (12), a second tying step (S44) of tying the coil reinforcement (12) and two horizontal reinforcements (11) while positioning the two horizontal reinforcements (11) on the inner middle height of the coil reinforcement (12), and a third tying step (S46) of tying the coil reinforcement (12) and two horizontal reinforcements (11) while positioning the two horizontal reinforcements (11) on the inner lower side of the coil reinforcement (12).

[0107] When the insertion of the above coil reinforcement (12) is completed, the coil reinforcement (12) and the two upper reinforcement bars (11a) are temporarily fastened (S42).

[0108] At this time, the above-mentioned temporary bonding is secured by a bonding line (15), and the bonding line (15) passes through 2 to 3 locations of the bonding position and temporarily bonds the horizontal reinforcing bar (11) and the coil reinforcing bar (12).

[0109] At this time, the upper reinforcing bar (11a) is supported by the reinforcing bar support piston (142) of the first reinforcing bar jig (130), and when the temporary fastening of the upper reinforcing bar (11a) is completed, the reinforcing bar support piston (142) of the second reinforcing bar jig (150) moves forward.

[0110] Four horizontal reinforcing bars (11) are placed on the reinforcing bar support piston (142) moved forward in this manner, and two horizontal reinforcing bars (11) are temporarily fastened to the middle height of the coil reinforcing bars (12) (S44).

[0111] When the temporary bonding of the above intermediate reinforcing bars (11b) is completed, the remaining two horizontal reinforcing bars (11) are temporary bonded to the lower part of the coil reinforcing bars (12) (S46).

[0112] The reinforcing bar ring unit (170) in which the horizontal reinforcing bar (11) and coil reinforcing bar (12) have been temporarily fastened is placed on a pair of rollers (175, see Fig. 7) installed on a lift (not shown).

[0113] With the above reinforcing bar ring unit (170) placed on the roller (175), a tie line (15) is tied to the remaining tie portion of the horizontal reinforcing bar (11) and the coil reinforcing bar (12) (S50).
