Description

Reinforcing bar support for assembling cages for tunnel construction and rebar support system for assembling cages for tunnel construction including the same

[0001] The present invention relates to a rebar support used in assembling a cage for tunnel construction and a rebar support system including the same.

[0002] In civil engineering work for tunnel construction, which is generally performed in mountainous terrain and urban areas, a concrete structure (T) as shown in Fig. 1 is installed for reinforcement after a hole is drilled in the terrain.

[0003] These concrete structures (T) are usually constructed by drilling holes, fabricating a frame with steel bars on site to match the shape of the holes, and then pouring concrete.

[0004] Large concrete structures (T) constructed manually on site like this not only take a long time to manufacture but also require a lot of labor costs, which increases the overall construction cost.

[0005] To solve these problems, attempts are being made to pre-manufacture cages (or steel frames) in factories through automated processes. However, for large structures such as tunnels, the main and transverse reinforcing bars that make up the cage are large, and various technological developments are still required to enable automated processes in factories.

[0006] For example, referring to FIG. 2, a cage for an arch-shaped concrete structure (T) is assembled by arranging arch-shaped first reinforcing bars (or main reinforcing bars) (P1) at predetermined intervals, intersecting a plurality of spaced first reinforcing bars (P1) with second reinforcing bars (or band reinforcing bars, transverse reinforcing bars) (P2), and weaving together the intersected first reinforcing bars (P1) and second reinforcing bars (P2).

[0007] In order to perform this as an automated process, it is necessary to develop automation technology for the process of placing multiple first reinforcing bars (P1) at a predetermined interval and supplying the second reinforcing bars (P2) by intersecting them with the multiple placed first reinforcing bars (P1).

[0008] The present invention is intended to solve the above-described problem and to provide a reinforcing bar holder for assembling a cage for tunnel construction in which a plurality of first reinforcing bars are automatically placed at predetermined intervals.

[0009] In addition, it is to provide a reinforcing bar placement system for assembling a cage for tunnel construction, which is automated and supplies second reinforcing bars to cross the first reinforcing bars that are spaced at predetermined intervals.

[0010] In order to solve the above-described problem, the present invention provides a reinforcing bar support for assembling a cage for tunnel construction, comprising: a support frame; a rod extending in one direction; and a support bar including a holder portion for receiving a first reinforcing bar supported at a front end of the rod so that the first reinforcing bar does not come off; a moving portion connected to the rod for moving the support bar forward or backward; a plurality of support units installed in the support frame spaced apart from each other in the vertical direction; and a first control portion for controlling the support units, so that the process of supporting the first reinforcing bar in a plurality of stages spaced apart from each other can be automated.

[0018] In one embodiment of the present invention, the tilting member may include the main member that moves in a direction parallel to the ground to move the longitudinal member upward or downward.

[0019] In one embodiment of the present invention, the first control unit can control the plurality of mounting units so that the first reinforcing bar is sequentially mounted from the mounting unit located at the bottom to the mounting unit located at the top.

[0020] In one embodiment of the present invention, the first control unit may control the tilting unit so that the front end of the rod tilts upward with respect to the mounting unit that mounts the first reinforcing bar located at the lowest end, or may control the tilting unit so that the front end of the rod tilts downward with respect to the mounting unit that mounts the first reinforcing bar located at the highest end.

[0021] Another embodiment of the present invention for solving the above-described problem is a system for placing reinforcing bars for assembling a cage for tunnel construction, comprising: a plurality of reinforcing bar holders arranged along the longitudinal direction of a first reinforcing bar; a reinforcing bar supplying unit that moves along the longitudinal direction of the first reinforcing bar and supplies a second reinforcing bar; and a second control unit that controls the plurality of reinforcing bar holders and the reinforcing bar supplying unit, wherein one of the first reinforcing bars is supported by the plurality of reinforcing bar holders arranged along the longitudinal direction of the first reinforcing bar, and the first reinforcing bars are placed in a plurality of stages spaced apart from each other on each of the reinforcing bar holders, and the second reinforcing bars are supplied at right angles to the first reinforcing bars placed in a plurality of stages, and the second control unit sequentially controls one of the plurality of holders so that a movement path of the reinforcing bar supplying unit is temporarily opened, so that an assembly process of a cage for tunnel construction including the first reinforcing bar and the second reinforcing bar intersecting therewith can be automated.

[0022] In one embodiment of the present invention, each of the rebar holders may include a support frame, a holder bar including a rod extending in one direction and a holder portion for receiving a first rebar placed at the front end of the rod so that it does not come off, a moving portion connected to the rod for moving the holder bar forward or backward, a plurality of mounting units installed on the support frame spaced apart from each other in the vertical direction, and a first control unit for controlling the mounting units according to a command from the second control unit.

[0023] In one embodiment of the present invention, the moving part may include a first cylinder installed on the support frame and arranged parallel to the ground, a first piston reciprocating the first cylinder, and a first link member connecting the rod and the first piston so that the rod moves in a direction parallel to the first piston.

[0024] In one embodiment of the present invention, the holder portion rotates in the circumferential direction of the rod to receive or discharge the first reinforcing bar, and the mounting unit may further include a rotating portion that rotates the mounting bar in the circumferential direction of the rod.

[0025] In one embodiment of the present invention, the load may be connected to the first link member so as to be rotatable in the circumferential direction of the load.

[0026] In one embodiment of the present invention, the rotating member may include at least one flat surface formed on the outer circumferential surface of the rod, an annular link member fitted to the rod and having an inner circumferential surface in contact with the flat surface, a second cylinder installed on the support frame, a second piston reciprocating the second cylinder, and a second link member connecting the annular link member and the second piston so that the annular link member rotates in the circumferential direction of the rod.

[0027] In one embodiment of the present invention, the mounting unit may further include a tilting part that tilts the front end of the load upward or downward.

[0028] In one embodiment of the present invention, the tilting member may include a third cylinder installed in the support frame and arranged parallel to the ground, a third piston that reciprocates the third cylinder, a longitudinal member that is connected between the front and rear ends of the rod and includes a slot in a path inclined at a predetermined angle from a direction parallel to the rod, and a main member that has one side connected to the third piston and the other side inserted into the slot so that the slot moves in a direction parallel to the third piston.

[0029] In one embodiment of the present invention, the first control unit can control the plurality of mounting units so that the first reinforcing bar is sequentially mounted from the mounting unit located at the bottom to the mounting unit located at the top.

[0030] In one embodiment of the present invention, the first control unit may control the tilting unit so that the front end of the rod tilts upward with respect to the mounting unit that mounts the first reinforcing bar located at the lowest end, or may control the tilting unit so that the front end of the rod tilts downward with respect to the mounting unit that mounts the first reinforcing bar located at the highest end.

[0031] The rebar support for assembling a cage for tunnel construction disclosed in the present invention and the rebar support system including the same have the advantage of being able to support the first rebar in multiple stages in the vertical direction through automation.

[0032] In addition, when placing the first reinforcing bar in multiple stages in the vertical direction according to automation, there is an advantage in that it can be placed sequentially from the bottom to the top.

[0033] In addition, among the first reinforcing bars temporarily placed in multiple stages in the vertical direction on the reinforcing bar rack, the first reinforcing bar placed at the top is lowered slightly downwards and the first reinforcing bar placed at the bottom is raised slightly upwards, so that the reinforcing bar supply unit can easily supply the second reinforcing bars, which has the advantage.

[0034] In addition, with automation, the rebar supply unit moves along the first rebar supported by the rebar holder and supplies the second rebar, and the movement path of the rebar supply unit is temporarily opened, which has the advantage of allowing the rebar supply unit to easily and quickly supply the second rebar.

[0057] Hereinafter, with reference to FIGS. 2 to 10, a reinforcing bar support for assembling a cage for tunnel construction according to one embodiment of the present invention will be described in detail.

[0058] Referring to FIGS. 2 and 3, a rebar holder (1000) for assembling a cage for tunnel construction disclosed in the present invention (hereinafter, the abbreviated name 'rebar holder (1000)' will be used interchangeably) is an automated device that holds or supports a first rebar (P1) corresponding to a main rebar in a cage for tunnel construction including a first rebar (P1) and a second rebar (P2) intersecting therewith.

[0059] For a first reinforcing bar (P1) that extends in one direction and is curved at a predetermined curvature, a reinforcing bar holder (1000) can support and support the first reinforcing bar (P1) between both ends of the first reinforcing bar (P1).

[0060] Referring to FIGS. 4 and 5, the steel bar support (1000) for assembling a cage for tunnel construction disclosed in the present invention may include a support frame (100), a support unit (200), and a first control unit (300).

[0061] The support frame (100) is a frame in which a mounting unit (200) can be built, and supports the mounting unit (200) so that a mounting bar (210) of the mounting unit (200), which will be described later, can move relative to the support frame (100).

[0062] The support frame (100) may be a rectangular parallelepiped frame, but is not limited thereto.

[0063] The mounting unit (200) is configured to mount the first reinforcing bar (P1) by moving the mounting bar (210) described later to the location where the first reinforcing bar (P1) is placed.

[0064] A plurality of mounting units (200) can be installed on the support frame (100). A plurality of mounting units (200) can be installed on the support frame (100) spaced apart from each other in the vertical direction. Accordingly, on each rebar mounting stand (1000), the first rebar (P1) can be arranged in the vertical direction and mounted in multiple stages spaced apart from each other.

[0065] Each mounting unit (200) may include a mounting bar (210), a moving part (220), a rotating part (230), and a tilting part (240).

[0066] The support bar (210) is a bar that supports and supports the first reinforcing bar (P1). The support bar (210) may include a rod (211) and a holder portion (212).

[0067] The rod (211) may be a bar extending in one direction. The rod (211) may be arranged so that both ends face forward and backward, respectively.

[0068] The holder part (212) is located at the front end of the load (211), and the first reinforcing bar (P1) is placed on the holder part (212).

[0069] The holder portion (212) has a function of receiving the first reinforcing bar (P1) that is being placed so that it does not come off. In addition, the holder portion (212) can rotate in the circumferential direction (D2) of the rod (211) to receive or discharge the first reinforcing bar (P1).

[0070] To this end, the holder portion (212) may be a structure that wraps around the outer circumference of the first reinforcing bar (P1) while leaving the upper portion of the first reinforcing bar (P1) open. For example, referring to Fig. 5, the holder portion (212) may be provided as a 'U'-shaped structure. However, the present invention is not limited thereto.

[0071] Referring to FIGS. 5 and 6, the moving part (220) is installed and supported on the support frame (100) and is configured to move the mounting bar (210) by the relative movement of the first cylinder (221) and the first piston (222). The moving part (220) is connected to the rod (211) and can move the mounting bar (210) forward or backward.

[0072] For this purpose, the moving part (220) may include a first cylinder (221), a first piston (222), and a first link member (223).

[0073] The first cylinder (221) is installed on the support frame (100) and can be arranged parallel to the ground. The two ends of the first cylinder (221) can be arranged to face forward and backward, respectively.

[0074] The first piston (222) reciprocates with respect to the first cylinder (221). The first piston (222) reciprocates by repeatedly inserting and discharging into the first cylinder (221). Accordingly, the first piston (222) can move forward and backward relative to the first cylinder (221).

[0075] The first link member (223) connects the rod (211) and the first piston (222). The first link member (223) can connect the rear end of the rod (211) and the rear end of the first piston (222).

[0076] The first link member (223) connects the rod (211) and the first piston (222) so that the rod (211) moves in a direction parallel to the first piston (222). To this end, the first link member (223) may be provided as a fixed plate that does not rotate or move relative to one side connecting the rod (211) and the other side connecting the first piston (222). However, this is not limited thereto.

[0077] The moving part (220) may further include a first measuring sensor (224) for precise control of the mounting bar (210). The first measuring sensor (224) may measure the relative movement distance of the first piston (222) with respect to the first cylinder (221). The first measuring sensor (224) may include a detection part (224-1) installed in the first cylinder (221), and a measuring bar (224-2) installed at the rear end of the first piston (222) or the first link member (223).

[0078] The measuring bar (224-2) moves along the rear end of the first piston (222) or the first link member (223), and can be inserted into the detection unit (224-1) when the first piston (222) is inserted into the first cylinder (221).

[0079] Since the length of the measuring bar (224-2) inserted into the detection unit (224-1) can be directly checked according to the control value of the moving unit (220), the movement of the holding bar (210) can be accurately and precisely controlled.

[0080] Referring to FIGS. 7 and 8, the rotating part (230) is configured to rotate the support bar (210) in the circumferential direction (D2) of the load (211).

[0081] As the rotating part (230) rotates the holder (210) in the circumferential direction (D2) of the load (211), the holder part (212) located at the front end of the load (211) can rotate together. The holder part (212) can rotate in the circumferential direction (D2) of the load (211) to receive the first reinforcing bar (P1) in the holder part (212) or discharge it from the holder part (212).

[0082] For this purpose, the load (211) can be connected to the first link member (223) so as to be rotatable.

[0083] The rod (211) can be connected to the first link member (223) so as to be rotatable in the circumferential direction (D2) of the rod (211). The rod (211) can be connected to the first link member (223) via a bearing.

[0084] Additionally, the rotating part (230) may include a flat surface (231), an annular link member (232), a second cylinder (233), a second piston (234), and a second link member (235).

[0085] The flat surface (231) may be formed on the outer surface of the rod (211). The flat surface (231) may be an engraved portion of the outer surface of the rod (211), as illustrated in FIG. 7. The flat surface (231) may be formed in a continuous form from one end of the rod (211) to the other end along the longitudinal direction of the rod (211) on the outer surface of the rod (211). The flat surfaces (231) may be formed in parallel on both sides of the outer surface of the rod (211) with the central axis of the rod (211) interposed therebetween to form a pair. However, the present invention is not limited thereto.

[0086] The annular link member (232) can be fitted to the load (211).

[0087] At this time, the inner surface of the annular link member (232) can be in contact with the flat surface (231) formed on the outer surface of the rod (211). If a plurality of flat surfaces (231) are formed on the rod (211), the inner surface of the annular link member (232) can be provided in a shape that can be in contact with all of the plurality of flat surfaces (231).

[0088] The annular link member (232) may be a structure including a body (232-1) that surrounds a rod (211) as illustrated in FIG. 8, and an abutment surface (232-2) provided in a shape that can come into contact with a flat surface (231) engraved on the outer surface of the rod (211) on the body (232-1). However, the present invention is not limited thereto.

[0089] The second cylinder (233) may be installed on the support frame (100). The second cylinder (233) may be arranged parallel to the ground, and may be arranged so that both ends are vertically aligned to the front and rear, respectively. However, this is not limited thereto. The second piston (234) reciprocates the second cylinder (233).

[0090] The second link member (235) connects the annular link member (232) and the second piston (234). The second link member (235) can move along the second piston (234) connected to one side. The second link member (235) can rotate the annular link member (232) connected to the other side in the circumferential direction (D2) of the rod (211).

[0091] The second link member (235) may be composed of a second-first link member (235-1) and a second-second link member (235-2), as illustrated in FIG. 7. The second-first link member (235-1) and the second-second link member (235-2) may be connected to the annular link member (232) and the second piston (234) on one side, respectively, and the second-first link member (235-1) and the second-second link member (235-2) may be connected to each other on the other side.

[0092] The second-first link member (235-1) is pulled by the second-second link member (235-2) moving away from the load (211) along the second piston (234), causing the annular link member (232) to rotate counterclockwise, and the second-first link member (235-1) is pushed by the second-second link member (235-2) moving toward the load (211) along the second piston (234), causing the annular link member (232) to rotate clockwise.

[0093] Referring to FIGS. 9 and 10, the tilting portion (240) is configured to tilt the front end of the load (211) upward or downward.

[0094] For this purpose, the tilting part (240) may include a third cylinder (241), a third piston (242), a longitudinal member (243), and a main member (244).

[0095] The third cylinder (241) is installed on the support frame (100) and can be arranged parallel to the ground. The third cylinder (241) can be arranged so that both ends face forward and backward. The third cylinder (241) can be installed at an angle toward the front of the support frame (100). This is to effectively tilt the front end of the rod (211).

[0096] The third piston (242) reciprocates with respect to the third cylinder (241). The third piston (242) can move forward and backward through the reciprocating motion.

[0097] The longitudinal member (243) can be connected between the front and rear ends of the rod (211). It is a member that wraps around and connects the outer surface of the rod (211). The longitudinal member (243) can include a slot (243-1) of a path inclined at a predetermined angle from a direction parallel to the rod (211).

[0098] As illustrated in Fig. 9, the end member (243) may be provided as a structure in which the outer surface of the rod (211) is wrapped around a portion connected to the rod (211) and extends forward and backward, but includes a slot (243-1). At this time, the slot (243-1) may have a path inclined at a predetermined angle from a direction parallel to the rod (211), as illustrated in Fig. 10. The path of the slot (243-1) may face upward or downward of the rod (211).

[0099] The main member (244) can have one side connected to the third piston (242). The other side of the main member (244) can be inserted into the slot (243-1) so that the slot (243-1) can move in a direction parallel to the third piston (242). As the main member (244) moves in the slot (243-1) in a direction parallel to the third piston (242), the longitudinal member (243) is pushed upward or downward, and accordingly, the rod (211) wrapped by the longitudinal member (243) also tilts upward or downward.

[0100] Specifically, referring to FIGS. 9 and 10, when the slot (243-1) of the longitudinal member (243) has a path facing upward of the load (211), when the main member (244) inserted into the slot (243-1) is connected to the third piston (242) and moves from the rear to the front (+x-axis direction), the longitudinal member (243) is pushed downward and tilts the front end of the load (211) downward.

[0101] Likewise, when the slot (243-1) of the longitudinal member (243) has a path facing downward of the load (211), when the main member (244) inserted into the slot (243-1) is connected to the third piston (242) and moves from the front to the rear (-x-axis direction), the longitudinal member (243) is lifted upward and tilts the front end of the load (211) upward.

[0102] The first control unit (300) is connected to a plurality of mounting units (200) installed on the support frame (100) and can control each mounting unit (200).

[0103] The first control unit (300) can control the first reinforcing bar (P1) to be sequentially placed on the reinforcing bar support (1000) from the bottom to the top so that the first reinforcing bar (P1) can be sequentially placed from the bottom to the top, starting from the placing unit (200) located at the bottom to operate sequentially.

[0104] Specifically, the mounting unit (200) located at the bottom of the rebar holder (1000) is controlled to position the mounting bar (210) to the position where the first rebar (P1) is placed, and when the first rebar (P1) is placed, the mounting unit (200) located at the top is controlled to similarly position the mounting bar (210) to the position where the first rebar (P1) is placed. By repeating this operation, the first rebar (P1) can be sequentially placed on the rebar holder (1000) from the bottom to the top.

[0105] The first control unit (300) can control the mounting unit (200) so that the first reinforcing bar (P1) positioned at the lowest stage slightly rises and the first reinforcing bar (P1) positioned at the highest stage slightly lowers, with respect to the first reinforcing bar (P1) mounted in multiple stages in the vertical direction on the reinforcing bar mounting stand (1000).

[0106] To this end, the mounting unit (200) that mounts the first reinforcing bar (P1) mounted at the bottom controls the tilting unit (240) so that the front end of the rod (211) tilts upward, and the mounting unit (200) that mounts the first reinforcing bar (P1) mounted at the top can control the tilting unit (240) so that the front end of the rod (211) tilts downward.

[0107] When the first control unit (300) wants to release the first reinforcing bar (P1) from the reinforcing bar placement state, the first control unit (300) rotates the placement bar (210) under the control of the rotating unit (230) to discharge the first reinforcing bar (P1) placed on the holder unit (212), and then moves the placement bar (210) away from the first reinforcing bar (P1) under the control of the moving unit (220).

[0108] In some cases, after the above process, the rotating part (230) can be controlled again to rotate the holder (210) to its original state.

The holder part (212) can rotate in the circumferential direction (D2) of the rod (211) to accommodate or discharge the first reinforcing bar (P1).

[0123] Referring to FIGS. 5 and 6, the moving part (220) is connected to the load (211). The moving part (220) moves the mounting bar (210) forward or backward. The moving part (220) may include a first cylinder (221), a first piston (222), and a first link member (223).

[0124] The first cylinder (221) is installed on the support frame (100) and can be arranged parallel to the ground. The first piston (222) reciprocates with respect to the first cylinder (221).

[0125] The first link member (223) connects the rod (211) and the first piston (222). The first link member (223) connects the rod (211) and the first piston (222) so that the rod (211) moves in a direction parallel to the first piston (222).

[0126] The moving part (220) may further include a first measurement sensor (224) for precise control of the mounting bar (210).

[0127] Referring to FIGS. 7 and 8, the rotating part (230) rotates the holder (210). The rotating part (230) can rotate the holder (210) in the circumferential direction (D2) of the rod (211). As the rotating part (230) rotates the holder (210) in the circumferential direction (D2) of the rod (211), the holder part (212) located at the front end of the rod (211) can rotate together. The holder part (212) can rotate in the circumferential direction (D2) of the rod (211) to accommodate the first reinforcing bar (P1) in the holder part (212) or discharge it from the holder part (212).

[0128] For this purpose, the load (211) can be connected to the first link member (223) so as to be rotatable.

[0129] The rod (211) can be connected to the first link member (223) so as to be rotatable in the circumferential direction (D2) of the rod (211). The rod (211) can be connected to the first link member (223) via a bearing.

[0130] Additionally, the rotating part (230) may include a flat surface (231), an annular link member (232), a second cylinder (233), a second piston (234), and a second link member (235).

[0131] At least one flat surface (231) can be formed on the outer surface of the rod (211). The annular link member (232) is fitted to the rod (211) and its inner surface can be in contact with the flat surface (231).

[0132] The second cylinder (233) can be installed on the support frame (100). The second piston (234) reciprocates the second cylinder (233).

[0133] The second link member (235) connects the annular link member (232) and the second piston (234). The second link member (235) can move along the second piston (234) connected to one side. The second link member (235) can rotate the annular link member (232) connected to the other side in the circumferential direction (D2) of the rod (211).

[0134] Referring to FIGS. 9 and 10, the tilting member (240) can tilt the front end of the load (211) upward or downward.

[0135] The tilting member (240) may include a third cylinder (241), a third piston (242), a longitudinal member (243), and a main member (244).

[0136] The third cylinder (241) is installed on the support frame (100) and can be arranged parallel to the ground. The third piston (242) reciprocates with respect to the third cylinder (241).

[0137] The longitudinal member (243) may be connected between the front and rear ends of the load (211). The longitudinal member (243) may include a slot (243-1) of a path inclined at a predetermined angle from a direction parallel to the load (211).

[0138] The main member (244) can be connected to the third piston (242) on one side. The other side of the main member (244) can be inserted into the slot (243-1) so that the slot (243-1) can move in a direction parallel to the third piston (242).

[0139] The first control unit (300) is connected to a plurality of mounting units (200) installed on the support frame (100) and can control each mounting unit (200). In addition, the first control unit (300) can control the mounting unit (200) according to a command from the second control unit (3000).

[0140] The first control unit (300) can control the first reinforcing bar (P1) to be sequentially placed on the reinforcing bar support (1000) from the bottom to the top so that the first reinforcing bar (P1) can be sequentially placed from the bottom to the top, starting from the placing unit (200) located at the bottom to operate sequentially.

[0141] The first control unit (300) can control the mounting unit (200) so that the first reinforcing bar (P1) positioned at the lowest stage slightly rises and the first reinforcing bar (P1) positioned at the highest stage slightly lowers, with respect to the first reinforcing bar (P1) mounted in multiple stages in the vertical direction on the reinforcing bar mounting stand (1000).

[0142] To this end, the mounting unit (200) that mounts the first reinforcing bar (P1) mounted at the bottom controls the tilting unit (240) so that the front end of the rod (211) tilts upward, and the mounting unit (200) that mounts the first reinforcing bar (P1) mounted at the top can control the tilting unit (240) so that the front end of the rod (211) tilts downward.

[0143] When the first control unit (300) wants to release the first reinforcing bar (P1) from the reinforcing bar placement state, the first control unit (300) rotates the placement bar (210) under the control of the rotating unit (230) to discharge the first reinforcing bar (P1) placed on the holder unit (212), and then moves the placement bar (210) away from the first reinforcing bar (P1) under the control of the moving unit (220).

[0144] In some cases, after the above process, the rotating part (230) can be controlled again to rotate the holder (210) to its original state.

[0145] The rebar supply unit (2000) is a device that supplies a second rebar (P2) that intersects the first rebar (P1) placed on the rebar holder (1000).

[0146] The rebar supply unit (2000) can move along the longitudinal direction (D1) of the first rebar (P1) to supply the second rebar (P2). At this time, the second rebar (P2) can be supplied in a state where the longitudinal direction of the second rebar (P2) intersects the longitudinal direction (D1) of the first rebar (P1). The second rebar (P2) can be supplied to the first rebar (P1) installed in multiple stages in a manner where the longitudinal direction of the second rebar (P2) and the longitudinal direction (D1) of the first rebar (P1) are perpendicular to each other.

[0147] Referring to FIG. 3 and FIG. 11, the second control unit (3000) is a control unit that controls the rebar placement system and can provide commands to the first control unit (300) of each rebar supply unit (2000).

[0148] The second control unit (3000) can control a plurality of reinforcing bar holders (1000) arranged along the longitudinal direction (D1) of the first reinforcing bar (P1) and a reinforcing bar supply unit (2000) that moves along the longitudinal direction (D1) of the first reinforcing bar (P1) and supplies the second reinforcing bar (P2).

[0149] The second control unit (3000) controls a plurality of reinforcing bar holders (1000) arranged along the longitudinal direction (D1) of the first reinforcing bar (P1) to place one of the first reinforcing bars (P1), and can simultaneously move the placing bar (210) of each reinforcing bar holder (1000) to a position where the first reinforcing bar (P1) in front is placed.

[0150] At this time, the distance at which the support bar (210) of each rebar support (1000) moves may vary depending on the gap between each rebar support (1000) and the first rebar (P1).

[0151] The second control unit (3000) can sequentially control any one of the plurality of supports so that the movement path of the rebar supply unit (2000) is temporarily opened.

[0152] Specifically, as illustrated in FIG. 2, in a state where the first reinforcing bar (P1) is supported by a plurality of reinforcing bar holders (1000), the second control unit (3000) controls an adjacent reinforcing bar holder (1000) to temporarily release the support of the first reinforcing bar (P1) and move the support bar (210) away from the first reinforcing bar (P1) when the reinforcing bar supply unit (2000) approaches along the longitudinal direction (D1) of the first reinforcing bar (P1), and when the reinforcing bar supply unit (2000) moves away, the support bar (210) is moved again to support the first reinforcing bar (P1).

[0153] According to the aforementioned configuration, the steel bar placement system for assembling a cage for tunnel construction of the present invention has the advantage of automatically performing the process of placing a main steel bar (or first steel bar (P1)) of considerable weight in multiple stages by separating them in the vertical direction and the process of supplying a second steel bar (P2) to intersect them under control.
