Description

Technical Field

[0001] This invention relates to the field of steel bar block assembly, and in particular to an automatic assembly device and method for U-shaped steel bar blocks. Background Technology

[0002] In the field of engineering, the steel reinforcement structure of reinforced concrete structures such as box girders and bridge towers is relatively complex. With the development of industrialized construction, automated production lines are widely used for the flexible processing and forming of various steel reinforcement blocks. For precast small box girders, the bottom plate steel reinforcement blocks and the left and right web plate steel reinforcement blocks are usually produced mechanically first. Then, these three blocks need to be assembled into U-shaped steel reinforcement components.

[0003] The current assembly process is mainly carried out in the steel bar production workshop, using two gantry cranes with specialized lifting equipment to sequentially lift the bottom slab steel bar blocks and the left / right side web steel bar blocks into U-shaped component jigs for assembly. The web steel bar blocks are initially in a flat position and require adjustment and turning using specialized lifting equipment and a turning jig for successful assembly. This traditional process suffers from problems such as cumbersome procedures, long gantry crane usage time, and long assembly cycles. Furthermore, because the bottom slab and web steel bar blocks need to be temporarily stored before assembly, a large storage area is required on-site, hindering efficient use of space resources. In addition, the assembly process... The process still requires multiple operators. Although it is an improvement over the traditional loose-binding rebar process, its effectiveness in achieving mechanization to replace manual labor and reducing manpower through intelligentization is limited. While overall assembly reduces labor intensity and the number of workers to some extent, the core objective of current industrialized construction technology for rebar components is to further improve product quality, achieve efficiency improvement with reduced manpower, reduce reliance on the skill level of operators, and improve the mechanization and intelligence level of rebar skeleton fabrication, thereby ensuring the stability and consistency of construction quality. Therefore, an automatic assembly device for U-shaped rebar blocks and its assembly method are proposed to solve the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide an automatic assembly device and method for U-shaped steel bar blocks, which solves the problems of insufficient mechanization and low efficiency in existing assembly technologies.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic assembly device and method for U-shaped steel bar blocks, wherein the U-shaped steel bar block is composed of a bottom plate steel bar block and two web plate steel bar blocks, comprising: The base plate frame includes a longitudinally arranged longitudinal slide rail and a longitudinal telescopic cylinder. A base plate support frame for placing the base plate steel reinforcement blocks is slidably mounted on the longitudinal slide rail. The telescopic end of the longitudinal telescopic cylinder is connected to the base plate support frame. A positioning component is provided on the top of the base plate support frame. There are two web plate frames, which are symmetrically arranged on both sides of the base plate frame. The web plate frame includes a transversely arranged transverse track and a transverse telescopic cylinder. A transverse support frame is slidably arranged on the transverse track. The telescopic end of the transverse telescopic cylinder is connected to the transverse support frame.

A tilting telescopic cylinder for controlling the tilting support frame is provided in the transverse support frame. A positioning and locking component is provided on the top of the tilting support frame.

[0006] In the preferred embodiment, the positioning component includes bottom plate comb grooves on the four sides of the top of the bottom plate support frame, which are used to engage the transverse stirrups and longitudinal bars of the bottom plate reinforcing steel blocks.

[0007] In the preferred embodiment, the positioning and locking components include web comb grooves on the four sides of the top of the flipping support frame, which are used to engage the transverse stirrups and longitudinal bars of the web steel reinforcement blocks. A baffle is provided on the outer side of the web comb groove near the bottom plate frame, and a locking mechanism is provided on the web comb groove on the other side.

[0008] In the preferred embodiment, the locking mechanism includes a driving device and a connecting shaft located next to the slot of the web comb groove. A locking hook is rotatably mounted on the connecting shaft. By rotating, the locking hook can lock the transverse stirrups of the web steel reinforcement block into the slot of the web comb groove. A telescopic groove is provided at the bottom of the side of the web comb groove, and a rack is slidably mounted on the telescopic groove. A toothed ring that meshes with the rack is provided at the rotating part of the locking hook. A driving gear that meshes with the rack is provided on the output shaft of the driving device.

[0009] In the preferred embodiment, both the base plate support frame and the flipping support frame are equipped with positioning adjustment mechanisms for accurately positioning and placing the base plate steel reinforcement blocks or the web steel reinforcement blocks. The positioning adjustment mechanism includes a Y-axis adjustment mechanism, an X-axis adjustment mechanism set on the Y-axis adjustment mechanism, and a Z-axis adjustment mechanism set on the X-axis adjustment mechanism. The Z-axis adjustment mechanism is equipped with an adjustment support platform, and the top surface of the adjustment support platform can be lowered to below the groove opening of the base plate comb groove or the web comb groove.

[0010] In the preferred embodiment, the Y-axis adjustment mechanism includes two Y-axis sliding support rods arranged along the Y-axis. A Y-axis moving frame is slidably mounted on the Y-axis sliding support rods. A Y-axis support seat is provided between the middle of the two Y-axis sliding support rods. A Y-axis telescopic cylinder arranged along the Y-axis is installed on the Y-axis support seat. The telescopic end of the Y-axis telescopic cylinder is connected to the Y-axis moving frame.

[0011] In the preferred embodiment, the X-axis adjustment mechanism includes two X-axis sliding support rods arranged along the X-axis on the Y-axis moving frame. The X-axis moving frame is slidably mounted on the X-axis sliding support rods. An X-axis support seat is provided between the middle of the two X-axis sliding support rods. An X-axis telescopic cylinder arranged along the X-axis is installed on the X-axis support seat. The telescopic end of the X-axis telescopic cylinder is connected to the X-axis moving frame. The Z-axis adjustment mechanism includes multiple Z-axis telescopic cylinders mounted on the X-axis moving frame, with an adjustment support platform mounted on the telescopic end of the Z-axis telescopic cylinders.

[0012] In the preferred embodiment, both the base plate support frame and the flipping support frame are equipped with a Y-axis positioning vision camera and an X-axis positioning vision camera on their inner sides. The Y-axis positioning vision camera corresponds to the first slot of the Y-axis in the base plate comb groove or the web comb groove, and the X-axis positioning vision camera corresponds to the first slot of the X-axis in the base plate comb groove or the web comb groove.

[0013] In the preferred embodiment, the adjustment method of the positioning adjustment mechanism is as follows: mark the bottom of the first transverse stirrup in the Y-axis and the bottom of the first longitudinal bar in the X-axis of the bottom plate steel reinforcement block or web steel reinforcement block; The bottom plate steel reinforcement blocks or web steel reinforcement blocks are horizontally hoisted onto the adjustable support platform in the raised state using a crane; Then, by adjusting the Y-axis and X-axis of the Y-axis adjustment mechanism and the X-axis adjustment mechanism, and by positioning the marker with the X-axis positioning vision camera and the Y-axis positioning vision camera, the bottom plate steel reinforcement block or web plate steel reinforcement block is adjusted to the placement position. Finally, the Z-axis telescopic cylinder lowers the adjustment support platform below the slot to complete the placement of the bottom plate steel reinforcement block or web plate steel reinforcement block. When the initial position of the bottom plate steel reinforcement block or the web steel reinforcement block is greater than the adjustment range of the positioning and adjustment mechanism, the adjustment target can be achieved by repeatedly adjusting the lowering, resetting, lifting and adjusting process of the support platform during the adjustment process.

[0014] The method includes: S1. The bottom slab steel reinforcement blocks and the two web steel reinforcement blocks are horizontally hoisted to the preset positions on the bottom slab jig and the two web jigs respectively, and the web steel reinforcement blocks on the web jigs are fixed. At this time, the transverse stirrups of the bottom slab steel reinforcement blocks and the two web steel reinforcement blocks are staggered and have gaps. S2. The flipping support frame is flipped by the flipping telescopic cylinder, carrying the web plate steel reinforcement block, and flipped to a preset angle; S3. By using the transverse telescopic cylinder to push the transverse support frame closer to the bottom plate frame, the transverse stirrups of the bottom plate steel reinforcement blocks and the web steel reinforcement blocks interpenetrate with each other. S4. The bottom plate support frame is moved longitudinally by the longitudinal telescopic cylinder, so that the transverse stirrups of the bottom plate steel bars and the web steel bars fit together, eliminating the gap reserved in step S1. S5. Supplement the longitudinal reinforcement at the connection between the transverse stirrups of the bottom slab reinforcement block and the web reinforcement block, and connect the cross connection points to form a U-shaped reinforcement block; S6. Disconnect the web plate formwork from the web plate steel reinforcement blocks, and reverse steps S3 and S2 to restore the web plate formwork. Then, use a lifting device to lift out the U-shaped steel reinforcement blocks so that the next U-shaped steel reinforcement block can be assembled.

[0015] This invention provides an automatic assembly device and method for U-shaped steel reinforcement blocks. By setting up a base plate support frame with longitudinal sliding function and symmetrically arranged flip-over web plate support frames, it achieves precise positioning, automatic avoidance, flipping assembly, and tight fitting of the base plate steel reinforcement blocks and web plate steel reinforcement blocks during the assembly process. The longitudinal movement of the base plate support frame effectively avoids interference problems of the transverse stirrups in the early stage of assembly, creating conditions for smooth insertion. The flip-over support frame, driven by a flipping telescopic cylinder, can smoothly and safely flip the web plate steel reinforcement blocks from a flat position to a vertical assembly posture, completely replacing the traditional manual or semi-mechanical flipping method that relies on lifting equipment and flipping support frames, significantly reducing operational risks. The moving web plate jig enables automatic rebar connection between the web plate and the bottom plate reinforcement blocks. The reverse movement of the bottom plate support frame eliminates gaps, ensuring a tight and reliable connection. The entire assembly process does not require frequent use of gantry cranes, significantly reducing equipment occupancy time and manpower. The device itself integrates three major functions: temporary storage, automatic turning, and assembly forming. This allows the bottom plate and web plate reinforcement blocks to be temporarily stored and assembled directly on the jig without additional storage space, effectively saving workshop space. Furthermore, through seamless integration with the automated rebar production line, it truly achieves continuous, efficient, and standardized operation of U-shaped rebar components, improving assembly efficiency and consistency of forming quality, and reducing reliance on operator skills.

Detailed Implementation

[0018] Example 1 like Figure 1-10 As shown, an automatic assembly device for U-shaped steel bar blocks is provided. The U-shaped steel bar blocks are composed of a bottom plate steel bar block 3 and two web plate steel bar blocks 4. The bottom plate steel bar block 3 and the two web plate steel bar blocks 4 are all produced by mechanized equipment. This is the prior art in this field, so it will not be described in detail here.

[0019] The automatic assembly device includes a base plate frame 1 and a web plate frame 2. The base plate frame 1 includes a longitudinally arranged longitudinal slide rail 10 and a longitudinal telescopic cylinder 14. In this embodiment, there are two longitudinal slide rails 10 and two longitudinal telescopic cylinders 14. The longitudinal slide rail 10 is fixed to the ground by anchor bolts. A base plate support frame 11 for placing the base plate steel reinforcement blocks 3 is slidably arranged on the longitudinal slide rail 10. The base plate support frame 11 is slidably engaged with the longitudinal slide rail 10 by a first pulley 12 at the bottom. The telescopic end of the longitudinal telescopic cylinder 14 is connected to the base plate support frame 11. One end of the longitudinal telescopic cylinder 14 is hinged to the ground, and the telescopic end is hinged to the base plate support frame 11. Thus, the longitudinal movement of the base plate support frame 11 can be realized by the extension and retraction of the longitudinal telescopic cylinder 14. A positioning component is provided on the top of the base plate support frame 11 for positioning the placement position of the base plate steel reinforcement blocks 3, which facilitates subsequent assembly.

[0020] There are two web plate frames 2, symmetrically arranged on both sides of the base plate frame 1. The web plate frame 2 includes transversely arranged transverse rails 20 and transverse telescopic cylinders 23. In this embodiment, there are four transverse rails 20, which are fixed to the ground by anchor bolts. There are three transverse telescopic cylinders 23. A transverse support frame 21 is slidably arranged on the transverse rails 20. The transverse support frame 21 is slidably engaged with the transverse rails 20 by a second pulley 22 at its bottom. The telescopic end of the transverse telescopic cylinder 23 is connected to the transverse support frame 21. One end of the transverse telescopic cylinder 23 is hinged to the ground, and the telescopic end is hinged to the transverse support frame 21, thereby allowing the transverse support frame 23 to move through the transverse rails 20. The extension and retraction of the telescopic cylinder 23 enables the lateral movement of the transverse support frame 21. A flip support frame 24 is hinged on the transverse support frame 21, and the hinge point between the two is located on the side near the bottom plate jig 1. A flip telescopic cylinder 25 is provided in the transverse support frame 21 to control the flip support frame 24 to flip. One end of the flip telescopic cylinder 25 is hinged on the bottom plate of the transverse support frame 21, and the telescopic end is hinged to the bottom of the flip support frame 24. Thus, the flip support frame 24 can be flipped by extending and retracting the flip telescopic cylinder 25. A positioning and locking component is provided on the top of the flip support frame 24 to position and fix the web reinforcement block 4, which facilitates subsequent assembly.

[0021] This design allows the bottom slab reinforcement blocks 3 and the two web reinforcement blocks 4 to be installed and assembled on the bottom slab jig 1 and the two web jig 2 respectively, according to the required assembly positions. The longitudinal sliding of the bottom slab support frame 11 prevents interference between the transverse stirrups of the bottom slab reinforcement blocks 3 and the web reinforcement blocks 4 during assembly, maintaining a certain gap between the transverse stirrups at the connection points and creating conditions for assembly. Then, the flipping support frame 24 flips the web reinforcement blocks 4 to the assembly angle. At this point, the web jig 2 maintains a certain distance from the bottom slab jig 1, providing a suitable position for assembly. The flipping process creates the necessary conditions, and after the flipping is complete, the transverse extension cylinder 23 pushes the transverse stirrups of the web reinforcement block 4 and the bottom plate reinforcement block 3 to interlock, achieving a preliminary connection. Then, the reverse movement of the bottom plate support frame 11 eliminates the gaps between the transverse stirrups, making the transverse stirrups of the web reinforcement block 4 and the bottom plate reinforcement block 3 fit together, creating conditions for connection, thus achieving automated assembly. The completed bottom plate reinforcement block 3 and web reinforcement block 4 can be directly placed on the bottom plate jig 1 or the web plate jig 2, avoiding the need for additional storage space.

[0022] In the preferred embodiment, the placement and positioning component includes bottom plate comb grooves 13 on the four sides of the top of the bottom plate support frame 11, which are used to engage the transverse stirrups and longitudinal bars of the bottom plate steel reinforcement block 1. The number of grooves on the bottom plate comb grooves 13 is matched with the transverse stirrups and longitudinal bars of the bottom plate steel reinforcement block 1, thereby realizing the transverse and longitudinal positioning of the bottom plate steel reinforcement block 1 during placement and ensuring the accuracy of assembly.

[0023] In the preferred embodiment, the positioning and locking components include web plate comb grooves 26 on the four sides of the top of the flipping support frame 24, which are used to engage the transverse stirrups and longitudinal bars of the web plate steel reinforcement blocks 4, thereby achieving transverse and longitudinal positioning of the web plate steel reinforcement blocks 4 when placed, ensuring the accuracy of assembly. In addition, a baffle 27 is provided on the outer side of the web plate comb grooves 26 near the bottom plate jig 1. The baffle 27 can provide bottom support for the web plate steel reinforcement blocks 4 during the flipping process to prevent them from slipping. A locking mechanism 28 is provided on the web plate comb grooves 26 on the other side. The locking mechanism 28 prevents the collapse due to the shift of the center of gravity during the flipping process.

[0024] The locking mechanism 28 includes a drive device 285 and a connecting shaft 280 located next to the slot of the web comb groove 26. A locking hook 281 is rotatably mounted on the connecting shaft 280, and an anti-disengagement cap is provided at the end of the connecting shaft 280 to prevent the locking hook 281 from disengaging. The locking hook 281 can lock the transverse stirrups of the web steel block 4 into the slot of the web comb groove 26 by rotation. At the same time, when the locking hook 281 is reversed and opened, it can completely disengage from the slot, avoiding affecting the normal installation of the web steel block 4. A telescopic slide groove 283 is provided at the bottom of the side of the web comb groove 26, and a rack 284 is slidably mounted on the telescopic slide groove 283. A toothed ring 282 that meshes with the rack 284 is provided at the rotating part of the locking hook 281. A drive gear 286 that meshes with the rack 284 is provided on the output shaft of the drive device 285.

[0025] With this design, the drive gear 286 can be rotated by the drive device 285, so that the rack 284 slides in the telescopic groove 283, and then through its meshing relationship with the locking hook 281, the locking hook 281 is driven to rotate, thereby achieving the effect of locking or unlocking the transverse stirrups of the web steel reinforcement block 4.

[0026] In this embodiment, the specific number of locking hooks 281 can be adjusted according to the locking requirements. In addition, the drive device 285 is composed of a motor and a reducer transmission combination, and has a self-locking function in the stopped state. This is prior art, so it will not be described in detail here.

[0027] In the preferred embodiment, in order to accurately place the bottom plate steel reinforcement block 3 or the web steel reinforcement block 4 on the bottom plate support frame 11 or the flipping support frame 24, and reduce manual interference during the placement process and the long-term occupation of the lifting equipment, both the bottom plate support frame 11 and the flipping support frame 24 are equipped with a positioning adjustment mechanism 15 for accurately positioning and placing the bottom plate steel reinforcement block 3 or the web steel reinforcement block 4. The positioning adjustment mechanism 15 includes a Y-axis adjustment mechanism, an X-axis adjustment mechanism set on the Y-axis adjustment mechanism, and a Z-axis adjustment mechanism set on the X-axis adjustment mechanism. An adjustment support platform 159 is set on the Z-axis adjustment mechanism, and the top surface of the adjustment support platform 159 can be lowered to below the groove opening of the bottom plate comb groove 13 or the web comb groove 26.

[0028] With this design, the adjustment support platform 159 can be raised to the top of the base plate support frame 11 or the flip support frame 24 via the Z-axis adjustment mechanism to support the base plate steel reinforcement block 3 or the web steel reinforcement block 4 before placement. At this time, the lifting device can be released, and then the base plate steel reinforcement block 3 or the web steel reinforcement block 4 can be adjusted to the placement position via the Y-axis adjustment mechanism and the X-axis adjustment mechanism. The placement of the base plate steel reinforcement block 3 or the web steel reinforcement block 4 is completed by the lowering of the adjustment support platform 159.

[0029] The Y-axis adjustment mechanism includes two Y-axis sliding support rods 150 arranged along the Y-axis. A Y-axis moving frame 151 is slidably mounted on the Y-axis sliding support rods 150. Specifically, the Y-axis moving frame 151 is slidably mounted on the two Y-axis sliding support rods 150 through four sleeve shafts set at the bottom. A Y-axis support seat 152 is set between the middle of the two Y-axis sliding support rods 150. A Y-axis telescopic cylinder 153 arranged along the Y-axis is installed on the Y-axis support seat 152. In this embodiment, there are two Y-axis support seats 152 and two Y-axis telescopic cylinders 153. The Y-axis support seat 152 is U-shaped, which can effectively reduce the installation height of the Y-axis telescopic cylinder 153. The telescopic end of the Y-axis telescopic cylinder 153 is connected to the Y-axis moving frame 151.

[0030] With this design, the Y-axis moving frame 151 can be moved along the Y-axis on the Y-axis sliding support rod 150 by extending and retracting the Y-axis telescopic cylinder 153.

[0031] In addition, the X-axis adjustment mechanism includes two X-axis sliding support rods 154 arranged along the X-axis on the Y-axis moving frame 151. An X-axis moving frame 155 is slidably mounted on the X-axis sliding support rods 154. Specifically, the X-axis moving frame 155 is slidably mounted on the two X-axis sliding support rods 154 by four sleeves set at the bottom. An X-axis support seat 156 is provided between the middle of the two X-axis sliding support rods 154. An X-axis telescopic cylinder 157 arranged along the X-axis is installed on the X-axis support seat 156. In this embodiment, there are two X-axis support seats 156 and two X-axis telescopic cylinders 157. The X-axis support seat 156 is U-shaped, which can effectively reduce the installation height of the X-axis telescopic cylinder 157. The telescopic end of the X-axis telescopic cylinder 157 is connected to the X-axis moving frame 155.

[0032] With this design, the X-axis moving frame 155 can be moved along the X-axis on the X-axis sliding support rod 154 by extending and retracting the X-axis telescopic cylinder 157.

[0033] The Z-axis adjustment mechanism includes multiple Z-axis telescopic cylinders 158 mounted on the X-axis moving frame 155. The specific number of Z-axis telescopic cylinders 158 can be adjusted according to actual needs. An adjustment support platform 159 is mounted on the telescopic end of the Z-axis telescopic cylinder 158, thereby adjusting the height of the X-axis moving frame 155 by telescopically extending or retracting the Z-axis telescopic cylinder 158.

[0034] It should be noted that the top of the base plate support frame 11 and the flip support frame 24 can be open or grid-shaped as shown in the attached figure of this embodiment. When it is grid-shaped, the grid openings on it should meet the requirements of the arrangement and adjustment movement of the positioning adjustment mechanism 15.

[0035] In the preferred embodiment, to further improve the positioning accuracy of the positioning adjustment mechanism 15, a Y-axis positioning vision camera 1510 and an X-axis positioning vision camera 1511 are respectively installed on the inner side of the base plate support frame 11 and the flipping support frame 24. The Y-axis positioning vision camera 1510 corresponds to the first slot of the base plate comb groove 13 or the web comb groove 26 along the Y-axis, and the X-axis positioning vision camera 1511 corresponds to the first slot of the base plate comb groove 13 or the web comb groove 26 along the X-axis. The specific installation locations are as follows: Figure 10 As shown, the Y-axis positioning vision camera 1510 and the X-axis positioning vision camera 1511 are connected to a corresponding visual recognition system.

[0036] With this design, the installation and positioning of the bottom plate steel reinforcement block 3 or the web plate steel reinforcement block 4 can be achieved through the recognition functions of the Y-axis positioning vision camera 1510 and the X-axis positioning vision camera 1511.

[0037] The specific adjustment method is as follows: mark the bottom of the first transverse stirrup in the Y-axis and the bottom of the first longitudinal bar in the X-axis of the bottom plate steel reinforcement block 3 or the web steel reinforcement block 4; The bottom plate steel reinforcement block 3 or the web plate steel reinforcement block 4 are horizontally hoisted onto the adjustable support platform 159 in the raised state using a crane. Then, by adjusting the Y-axis and X-axis of the Y-axis adjustment mechanism and the X-axis adjustment mechanism, and by positioning the marker with the X-axis positioning vision camera 1511 and the Y-axis positioning vision camera 1510, the bottom plate steel reinforcement block 3 or the web plate steel reinforcement block 4 is adjusted to the placement position. Finally, the Z-axis telescopic cylinder 158 lowers the adjustment support platform 159 below the slot to complete the placement of the bottom plate steel reinforcement block 3 or the web plate steel reinforcement block 4. When the initial position of the bottom plate steel reinforcement block 3 or the web plate steel reinforcement block 4 is greater than the adjustment range of the positioning adjustment mechanism 15, the adjustment target can be achieved by repeatedly adjusting the lowering, resetting, lifting and adjusting process of the support platform 159 during the adjustment process.

[0038] Example 2 Further explanation in conjunction with Example 1, such as Figure 11-16 The structure shown, according to the assembly method of the automatic assembly device for U-shaped steel bar blocks described in Embodiment 1, includes: S1. The bottom plate steel reinforcement block 3 and the two web plate steel reinforcement blocks 4 are horizontally hoisted to the preset positions on the bottom plate jig 1 and the two web plate jig 2 respectively, and the web plate steel reinforcement blocks 4 on the web plate jig 2 are fixed. At this time, the transverse stirrups of the bottom plate steel reinforcement block 3 and the two web plate steel reinforcement blocks 4 are staggered and there are gaps.

[0039] S2. The flipping support frame 24 is flipped by the flipping telescopic cylinder 25, carrying the web steel bar block 4, and flipped to a preset angle.

[0040] S3. The transverse telescopic cylinder 23 pushes the transverse support frame 21 closer to the bottom plate frame 1, so that the transverse stirrups of the bottom plate steel reinforcement block 3 and the web plate steel reinforcement block 4 interweave with each other.

[0041] S4. The longitudinal telescopic cylinder 14 pushes the bottom plate support frame 11 to move longitudinally, so that the transverse stirrups of the bottom plate steel reinforcement block 3 and the web plate steel reinforcement block 4 fit together, eliminating the gap reserved in step S1.

[0042] S5. Supplement the longitudinal reinforcement at the connection between the bottom slab reinforcement block 3 and the web reinforcement block 4 with the transverse stirrups, and connect the cross connection points to form a U-shaped reinforcement block.

[0043] S6. Disconnect the web plate formwork 2 from the web plate steel bar block 4, and reverse steps S3 and S2 to restore the web plate formwork 2. Then, lift the U-shaped steel bar block out using a lifting device, and then proceed with the assembly of the next U-shaped steel bar block.

[0044] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
