Description

Technical Field

[0001] This invention relates to the field of shear wall technology, and more specifically, to an integrated precast shear wall. Background Technology

[0002] Integrated precast shear walls are building components that are prefabricated in a factory and are an important part of prefabricated buildings. These shear walls are manufactured in the factory using high-precision molds and advanced production processes, combining materials such as steel bars and concrete into an integral wall structure according to design requirements. The design and manufacturing process fully considers various requirements such as the mechanical performance, waterproof performance, and thermal insulation performance of the building structure.

[0003] When connecting integrated precast shear walls to the ground foundation, sleeve grouting is a common connection method. During the factory production of precast shear walls, sleeves are usually pre-embedded at the bottom of the shear wall. The bottom of the longitudinal reinforcement of the shear wall is placed inside the sleeve. The outer wall of the shear wall is provided with grouting holes and grout outlet holes that communicate with the inside of the sleeve. During installation, the sleeve at the bottom of the shear wall is aligned with the reinforcement on the ground, so that the reinforcement is inserted into the sleeve. Then, high-strength grout is injected from the grouting holes. The grout fills the sleeve densely, and after hardening, it firmly connects the two reinforcements together. In actual construction, due to the numerous sleeves at the bottom of the shear wall, workers may need to repeatedly adjust the position of the shear wall to ensure that every steel bar on the ground is inserted into the sleeve. Because the shear wall is heavy, the adjustment process is cumbersome, leading to reduced construction efficiency. Therefore, we propose an integrated precast shear wall system.

[0014] Preferably, the baffle is arranged at the top of the guide cylinder, the baffle is used to restrict the upward movement of the guide cylinder, and the baffle, together with the limiting block, keeps the guide cylinder in a fixed state.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by designing a guiding component, a fastening and straightening component, and a locking component within the longitudinal cylinder of the sleeve grouting assembly, allows the shear wall body to quickly and smoothly guide the ground-mounted reinforcing bars through the fixed guiding component and insert them into the longitudinal cylinder cavity. During the insertion process, the fastening and straightening component rises, fastening and straightening the reinforcing bars and improving their stability within the longitudinal cylinder. The locking component, in conjunction with the fastening and straightening component, causes the guiding component to transition from a fixed to a movable state. The movable guiding component follows the reinforcing bars as it rises into the shear wall body, preventing it from affecting the adhesion between the shear wall body and the ground. Grouting is then performed through the grouting input pipe into the longitudinal and transverse cylinder cavities, connecting the reinforcing bars with the secondary structural transverse and longitudinal reinforcing bars to form a stable and secure connection. The entire process is seamless. The guiding component guides the ground-mounted reinforcing bars into the longitudinal cylinder cavity, providing auxiliary alignment and reducing the difficulty for workers adjusting the position of the shear wall body, making the adjustment process easier and improving work efficiency.

[0016] 2. This invention designs the top of the guide tube as a straight cylindrical structure to match the shape of the inner cavity of the longitudinal tube, and the bottom as a conical cylindrical structure to match the shape of the conical cavity. The bottom opening of the conical cylindrical structure is relatively large, making it easier to align the reinforcing bar with the bottom of the guide tube. During the insertion of the reinforcing bar into the guide tube, the conical cylindrical structure of the guide tube can guide the insertion path, allowing the reinforcing bar to quickly and accurately enter the straight cylindrical structure of the guide tube and then be inserted into the inner cavity of the longitudinal tube. By designing the guide tube, the difficulty of aligning the reinforcing bar between the shear wall body and the ground is reduced, further improving the accuracy and speed of alignment, and increasing work efficiency.

[0017] 3. The present invention also designs four sliding pillars on the fixing ring at the bottom of the guide tube that fit into the insertion cavity. The guide tube can maintain a relatively stable structural state through the four sliding pillars, so that the guide tube is not easy to shake during the insertion of the reinforcing bar, ensuring that the reinforcing bar is accurately inserted into the inner cavity of the longitudinal tube, and further improving the accuracy and stability of aligning the shear wall body with the ground reinforcing bar.

[0018] 4. During the insertion of the reinforcing bar into the inner cavity of the longitudinal cylinder, the top of the reinforcing bar pushes the pull plate to slide upward along the movable groove. The pull plate drives two fastening blocks to slide upward along the T-shaped groove through two pull rods. At this time, the fastening blocks and the reinforcing bar move upward synchronously and remain relatively stationary in the vertical direction. By designing the T-shaped groove as an inclined groove structure that matches the side wall of the inclined block, the fastening block gradually approaches the reinforcing bar in the horizontal direction during its ascent. The fastening block is constrained by the arc surface structure of the inclined state of the two symmetrically arranged inclined blocks, and the space above it gradually narrows. This causes the fastening block to be squeezed between the inclined block and the reinforcing bar, forming a fastening effect to straighten the reinforcing bar and ensuring that the reinforcing bar remains vertical and fixed in the inner cavity of the longitudinal cylinder. This allows the grout to be distributed more evenly around the reinforcing bar when grouting the inner cavity of the longitudinal cylinder, improving the reliability and firmness of the connection between the reinforcing bar and the secondary structure's horizontal and longitudinal reinforcing bars.

[0019] 5. In this invention, when the top of the reinforcing bar pushes the fastening and straightening assembly upward, the fastening block drives the pull strap connected to its bottom to rise within the guide channel of the guide frame. During the rise of the pull strap, the second tooth on its side wall drives the rotating circular plate to rotate within the semi-circular groove through the first tooth. The rope groove on the side wall of the rotating circular plate pulls the wire rope upward, thereby driving the traction column and the reinforcing bar to rise. At this time, the reinforcing bar loses its insertion function onto the baffle. The baffle is subjected to the elastic force of the first spring, causing the baffle to slide inward within the sliding groove, thereby causing the baffle to lose its function of restricting the upward movement of the guide cylinder. As the reinforcing bar is gradually inserted into the inner cavity of the longitudinal cylinder, the shear wall body gradually comes into contact with the ground, driving the guide cylinder to rise into the conical cavity. This avoids the guide assembly affecting the degree of contact between the shear wall body and the ground, completing the contact operation between the shear wall body and the ground. Through the linkage between the locking assembly and the fastening and straightening assembly, the guide assembly is driven to rise, making the construction process an automated and continuous operation, further improving work efficiency.

Detailed Implementation

[0022] like Figures 1 to 15 As shown, the present invention relates to an integrated precast shear wall, comprising a shear wall body 1, wherein multiple main structural transverse steel bars 2, multiple secondary structural transverse steel bars 3, multiple main structural longitudinal steel bars 4, multiple secondary structural longitudinal steel bars 5, and multiple sleeve grouting components 6 are arranged inside the shear wall body 1.

[0023] In an embodiment of the present invention, the main structural transverse reinforcement 2 is arranged between the main structural longitudinal reinforcement 4 and the secondary structural longitudinal reinforcement 5. The secondary structural transverse reinforcement 3 is connected to the main structural longitudinal reinforcement 4 through connecting reinforcement 7. The reinforcement of the main structural transverse reinforcement 2 is tied to the reinforcement of the main structural longitudinal reinforcement 4 and the secondary structural longitudinal reinforcement 5. The reinforcement is pre-tied and embedded in the concrete of the shear wall body 1, so that the shear wall body 1 forms an integrated structure. The sleeve grouting assembly 6 includes a longitudinal cylinder 61 and two transverse cylinders 62. The two transverse cylinders 62 are symmetrically distributed on both sides of the longitudinal cylinder 61. One end of 62 is connected to the outer wall of the longitudinal cylinder 61. The inner cavities of the longitudinal cylinder 61 and the transverse cylinder 62 are connected. The outer wall of the longitudinal cylinder 61 is connected to a grouting input pipe 63 and a grouting exhaust pipe 64 that are connected to its inner cavity. The grouting input pipe 63 is connected to an external grouting device. The external grouting device injects grout into the inner cavities of the longitudinal cylinder 61 and the transverse cylinder 62 through the grouting input pipe 63. The grouting input pipe 63 and the grouting exhaust pipe 64 penetrate the side wall of the shear wall main body 1. The bottom end of the secondary structural longitudinal steel bar 5 is arranged in the inner cavity of the longitudinal cylinder 61, and one end of the secondary structural transverse steel bar 3 is arranged in the inner cavity of the transverse cylinder 62.

[0024] In an embodiment of the present invention, the sleeve grouting assembly 6 further includes a guide assembly 65 disposed at the lower end of the inner cavity of the longitudinal cylinder 61 and a fastening and straightening assembly 66 disposed in the inner cavity of the longitudinal cylinder 61. A locking assembly 67 is disposed between the guide assembly 65 and the fastening and straightening assembly 66. The locking assembly 67 is linked and cooperates with the fastening and straightening assembly 66. The locking assembly 67 is used to control the guide assembly 65 to be in a fixed state or a movable state. The shear wall body 1 guides the ground reinforcing bars 8 through the fixed state guide assembly 65 and inserts them into the inner cavity of the longitudinal cylinder 61. The reinforcing bars 8 drive the fastening and straightening. As component 66 rises, it tightens and straightens the reinforcing bar 8. Simultaneously, the tightening and straightening component 66 drives the locking component 67 to unlock the guiding component 65, making the guiding component 65 movable. It then rises along with the reinforcing bar 8, completing the connection between the reinforcing bar 8 and the sleeve grouting component 6. Grout is then injected into the inner cavities of the longitudinal cylinder 61 and the transverse cylinder 62 through the grouting input pipe 63, connecting the reinforcing bar 8 to the secondary structural transverse reinforcing bars 3 and the secondary structural longitudinal reinforcing bars 5. This invention, by designing the guiding component 65, the tightening and straightening component 66, and the locking component 67 within the longitudinal cylinder 61 of the sleeve grouting component 6, enables… The shear wall body 1 can quickly and smoothly guide the ground reinforcing bars 8 through the fixed guide component 65 and insert them into the inner cavity of the longitudinal tube 61. During the insertion of the reinforcing bars 8, the fastening and straightening component 66 is raised, which can fasten and straighten the reinforcing bars 8, improving the stability of the reinforcing bars 8 in the longitudinal tube 61. The locking component 67 and the fastening and straightening component 66 work together to change the guide component 65 from a fixed state to a movable state. The movable guide component 65 rises with the reinforcing bars 8 and enters the shear wall body 1. This avoids the guide component 65 affecting the fit between the shear wall body 1 and the ground. Grouting is injected into the inner cavity of the longitudinal cylinder 61 and the transverse cylinder 62 through the grouting input pipe 63, so that the reinforcing bars 8 are connected with the secondary structural transverse reinforcing bars 3 and the secondary structural longitudinal reinforcing bars 5, forming a stable and firm connection. The whole process is completed in one go. The guide component 65 guides the reinforcing bars 8 on the ground to insert them into the inner cavity of the longitudinal cylinder 61, forming an auxiliary alignment function, which greatly improves the efficiency of workers in adjusting the position of the shear wall body 1, making the adjustment process easier and improving work efficiency.

[0025] In another embodiment of the present invention, the side wall of the horizontal cylinder 62 is connected to the upper side wall of the vertical cylinder 61 through a connecting pipe 68. The inner cavity of the horizontal cylinder 62 is connected to the inner cavity of the vertical cylinder 61 through the connecting pipe 68. When the grout is injected into the inner cavity of the horizontal cylinder 62, the air in the inner cavity of the horizontal cylinder 62 can be discharged into the upper end of the inner cavity of the vertical cylinder 61 through the connecting pipe 68 and discharged through the grouting exhaust pipe 64. By designing the connecting pipe 68, when the grouting input pipe 63 injects grout into the inner cavities of the vertical cylinder 61 and the horizontal cylinder 62, the grout can be smoothly filled into the inner cavity of the horizontal cylinder 62.

[0026] In another embodiment of the present invention, a thickened cylinder 6101 is integrally formed at the bottom of the longitudinal cylinder 61. The thickened cylinder 6101 has a conical cavity 6102 and four insertion cavities 6103 at its bottom. A limiting cavity 6104 is formed at the top of the insertion cavity 6103. A sliding groove 6105 is formed on the inner circumference of the thickened cylinder 6101. There are two sliding grooves 6105, which are symmetrically distributed. A control groove 6106 is formed on the bottom surface of the sliding groove 6105. A locking groove 6107 is formed on the top surface of the locking groove 6107. A wire groove 6108 is formed on the top surface of the locking groove 6107. A semi-circular groove 6110 is formed on the top of the wire groove 6108. The wire groove 6108 communicates with the inner cavity of the longitudinal cylinder 61 through the semi-circular groove 6110. Four movable grooves 6109 are arranged in a ring at equal intervals on the inner circumference of the longitudinal cylinder 61.

[0027] In another embodiment of the present invention, the guiding component 65 includes a guiding cylinder 6501 disposed within the inner cavity of the thickened cylinder 6101. The top of the guiding cylinder 6501 is a straight cylindrical structure that matches the shape of the inner cavity of the longitudinal cylinder 61, and the bottom is a conical cylindrical structure that matches the shape of the conical cavity 6102. By designing the top of the guiding cylinder 6501 as a straight cylindrical structure that matches the shape of the inner cavity of the longitudinal cylinder 61 and the bottom as a conical cylindrical structure that matches the shape of the conical cavity 6102, the present invention provides a larger bottom opening for the conical cylindrical structure, making it easier for the reinforcing bar 8 to be aligned with the bottom of the guiding cylinder 6501. During the insertion of the reinforcing bar 8 into the guiding cylinder 6501, the conical cylindrical structure of the guiding cylinder 6501 can guide the insertion path, enabling the reinforcing bar 8 to quickly and accurately enter the straight cylindrical structure of the guiding cylinder 6501 and be inserted into the inner cavity of the longitudinal cylinder 61 through the straight cylindrical structure. By designing the guiding cylinder 6501, the difficulty of aligning the reinforcing bar 8 between the shear wall body 1 and the ground is reduced, further improving the accuracy and speed of alignment. This improves work efficiency; a fixing ring 6502 is connected to the bottom outer wall of the guide cylinder 6501, and four sliding pins 6503 that fit into the insertion cavity 6103 are connected to the top surface of the fixing ring 6502. A limiting block 6504 arranged in the limiting cavity 6104 is connected to the top of the sliding pins 6503. The guide cylinder 6501 is movablely engaged with the thickened cylinder 6101 through the sliding pins 6503 and the limiting block 6504. The limiting block 6504 is used to limit the guide cylinder 6501 from sliding downward; This invention Furthermore, by designing four sliding posts 6503 on the fixing ring 6502 at the bottom of the guide tube 6501 that fit into the insertion cavity 6103, the guide tube 6501 can maintain a relatively stable structural state through the four sliding posts 6503. This ensures that the guide tube 6501 is not prone to shaking during the insertion of the reinforcing bar 8, thus guaranteeing that the reinforcing bar 8 is accurately inserted into the inner cavity of the longitudinal tube 61. This further improves the accuracy and stability of aligning the shear wall body 1 with the ground reinforcing bar 8.

[0028] In another embodiment of the present invention, the fastening and straightening assembly 66 includes two symmetrically arranged inclined blocks 6601 integrally formed with the inner circumferential wall of the longitudinal cylinder 61. The sidewalls of the inclined blocks 6601 are inclined arc-shaped structures. A T-shaped groove 6602 is provided on the sidewall of the inclined blocks 6601. The T-shaped groove 6602 is an inclined groove structure that matches the sidewall of the inclined blocks 6601. The cross-section of the T-shaped groove 6602 is T-shaped. A fastening block 6603 is arranged on the sidewall of the inclined blocks 6601. A T-shaped plate 6605 arranged in the T-shaped groove 6602 is connected to the sidewall of the fastening block 6603. The fastening block 6603 is connected to the inclined blocks through the T-shaped plate 6605. 6601 Sliding fit; the other side wall of the fastening block 6603 is connected to an extrusion plate 6604, which is a flexible arc plate structure. The extrusion plate 6604 is used to extrude the reinforcing bar 8 to ensure that the reinforcing bar 8 is fastened and straightened in the inner cavity of the longitudinal cylinder 61 and maintains a stable state; the top surface of the fastening block 6603 is movably connected to a pull rod 6606, and the top of the pull rod 6606 is movably connected to a pull plate 6607. The side wall of the pull plate 6607 is integrally formed with four sliding plates 6608 that slide in fit with the movable groove 6109. The sliding plates 6608 are arranged in the movable groove 6109. The inside of the pull plate 6607 is a cross-shaped hollow plate. The structure is hollow, with the sidewalls designed as concave arc surfaces. The pull plate 6607 is fitted with the inner circumferential wall of the longitudinal cylinder 61 through the concave arc surface of the sidewalls. During the insertion of the insert rib 8 into the inner cavity of the longitudinal cylinder 61, the top of the insert rib 8 pushes the pull plate 6607 to slide upward along the movable groove 6109. The pull plate 6607 drives the two fastening blocks 6603 to slide upward along the T-shaped groove 6602 through the two pull rods 6606 respectively. At this time, the fastening blocks 6603 and the insert rib 8 move upward synchronously and remain relatively stationary in the vertical direction. By designing the T-shaped groove 6602 as an inclined groove structure that matches the sidewall of the inclined block 6601, the fastening blocks 6603 can be effectively engaged. As the fixing block 6603 rises, it gradually approaches the reinforcing bar 8 in the horizontal direction. Due to the influence of the inclined arc surface structure of the two symmetrically arranged inclined blocks 6601, the space above the fixing block 6603 gradually narrows, causing the fixing block 6603 to be squeezed between the inclined blocks 6601 and the reinforcing bar 8, thus forming a tightening effect on the reinforcing bar 8 and ensuring that the reinforcing bar 8 remains vertical and fixed in the inner cavity of the longitudinal cylinder 61. This allows the grout to be distributed more evenly around the reinforcing bar 8 when grouting the inner cavity of the longitudinal cylinder 61, improving the reliability and firmness of the connection between the reinforcing bar 8 and the secondary structural horizontal reinforcing bar 3 and the secondary structural longitudinal reinforcing bar 5.

[0029] In another embodiment of the present invention, the locking component 67 includes a baffle 6701 disposed in the slide groove 6105, the baffle 6701 being disposed at the top of the guide cylinder 6501, the baffle 6701 being used to restrict the upward movement of the guide cylinder 6501, the baffle 6701 cooperating with the limiting block 6504 to keep the guide cylinder 6501 in a fixed state, the bottom surface of the baffle 6701 being connected to a driving block 6702, the driving block 6702 being disposed in the control groove 6106, the inner side wall of the control groove 6106 being connected to a fixing rod 6703 penetrating the side wall of the driving block 6702, the baffle 6701 being slidably engaged with the fixing rod 6703 through the driving block 6702, and the outer circumferential wall of the fixing rod 6703 being sleeved with Spring 6704 is positioned between the drive block 6702 and the inner wall of the control groove 6106. A slot 6705 is provided on the top surface of the baffle 6701, into which a plug 6706 is inserted. The top of the plug 6706 is positioned within the lock groove 6107, and a traction post 6707 is connected to its top surface. The top of the traction post 6707 penetrates the inner top surface of the lock groove 6107 and extends into the wire groove 6108. The traction post 6707 slides within the inner top surface of the lock groove 6107. Spring 6708 is fitted around the outer circumference of the traction post 6707, positioned between the plug 6706 and the inner top surface of the lock groove 6107. Through the elastic force of spring 6708, the insert 6706 is kept inserted into the slot 6705 on the top surface of the baffle 6701, forming an insertion connection with the baffle 6701, making it difficult for the baffle 6701 to slide in the groove 6105, thereby limiting the upward movement of the guide cylinder 6501. A steel wire rope 6709 is connected to the top surface of the traction column 6707, and the steel wire rope 6709 is arranged in the wire groove 6108. The locking assembly 67 also includes a rotating circular plate 6710 rotatably arranged on the inner side wall of the semi-circular groove 6110. The outer circumference of the rotating circular plate 6710 is provided with multiple teeth 6711, and a rope groove 67 is also provided on the outer circumference of the rotating circular plate 6710. 12. The top of the wire rope 6709 is connected to the inner wall of the rope groove 6712; a guide frame 6713 connected to the inner circumference of the longitudinal cylinder 61 is arranged on the side of the semi-circular groove 6110. The top surface of the guide frame 6713 has a slot, and the bottom surface of the guide frame 6713 has a slot with the same structure as the top surface. The guide frame 6713 forms a guide channel through the slot; a pull strap 6714 connected to the bottom surface of the fastening block 6603 is arranged in the guide channel. The side wall of the pull strap 6714 is provided with multiple teeth 6715 that mesh with the teeth 6711; the pull strap 6714 is movably matched with the guide channel of the guide frame 6713. The pull strap 6714 is a strip structure made of flexible material.In this invention, when the top of the insert 8 pushes the fastening and straightening assembly 66 upward, the fastening block 6603 drives the pull strap 6714 connected to its bottom to rise within the guide channel of the guide frame 6713. During the upward movement of the pull strap 6714, the second tooth 6715 on its side wall drives the rotating circular plate 6710 to rotate within the semi-circular groove 6110 through the first tooth 6711. The rope groove 6712 on the side wall of the rotating circular plate 6710 pulls the wire rope 6709 upward, thereby driving the traction column 6707 and the insert block 6706 to rise. At this time, the insert block 6706 loses its insertion function on the baffle 6701, and the baffle 6701 is subjected to the elastic force of the first spring 6704. The function of the guide component 65 is to allow the baffle 6701 to slide inward within the groove 6105, thereby removing the baffle 6701's function of restricting the upward movement of the guide cylinder 6501. As the reinforcing bars 8 are gradually inserted into the inner cavity of the longitudinal cylinder 61, the shear wall body 1 gradually comes into contact with the ground, causing the guide cylinder 6501 to rise and enter the cone cavity 6102. This prevents the guide component 65 from affecting the degree of contact between the shear wall body 1 and the ground, completing the contact operation between the shear wall body 1 and the ground. Through the linkage between the locking component 67 and the fastening and straightening component 66, the guide component 65 is driven to rise, making the construction process an automated and continuous operation, further improving work efficiency.

[0030] Working Principle: This embodiment provides an integrated precast shear wall. During use, the shear wall body 1 is lifted by external hoisting equipment and moved above the ground reinforcing bars 8. The bottom of the shear wall body 1 is gradually moved closer to the reinforcing bars 8, and adjustments are made by staff to align the guide tube 6501 at the bottom of the shear wall body 1 with the reinforcing bars 8. During the insertion of the reinforcing bars 8 into the guide tube 6501, the conical cylindrical structure of the guide tube 6501 guides the insertion path, allowing the reinforcing bars 8 to quickly and accurately enter the straight cylindrical structure of the guide tube 6501 and then into the inner cavity of the longitudinal cylinder 61. The top of the reinforcing bars 8 pushes the pull plate within the inner cavity of the longitudinal cylinder 61. 6607 slides upward along the movable groove 6109. The pull plate 6607 drives the two fastening blocks 6603 to slide upward along the T-shaped groove 6602 via two pull rods 6606. At this time, the fastening blocks 6603 and the insert 8 move upward synchronously and remain relatively stationary in the vertical direction. By designing the T-shaped groove 6602 as an inclined groove structure that matches the side wall of the inclined block 6601, the fastening block 6603 gradually approaches the insert 8 in the horizontal direction during its ascent. The fastening block 6603 is constrained by the arc surface structure of the inclined state of the two symmetrically arranged inclined blocks 6601, and the space above it gradually narrows, causing the fastening block 6603 to be squeezed against the inclined block 6601. Between block 6601 and insert 8, a fastening effect is formed on insert 8 to straighten it. At the same time, when the top of insert 8 pushes the fastening and straightening component 66 to rise, fastening block 6603 drives the pull strap 6714 connected to its bottom to rise in the guide channel of guide frame 6713. During the rise of pull strap 6714, the second tooth 6715 on its side wall drives the rotating circular plate 6710 to rotate in the semi-circular groove 6110 through the first tooth 6711. The rope groove 6712 on the side wall of rotating circular plate 6710 pulls the wire rope 6709 to rise, thereby driving the traction column 6707 and insert block 6706 to rise. At this time, insert block 6706 loses its insertion into baffle 6701. The baffle 6701 is subjected to the elastic force of spring 6704, causing the baffle 6701 to slide inward in the groove 6105. This causes the baffle 6701 to lose its function of restricting the upward movement of the guide cylinder 6501. As the reinforcing bar 8 is gradually inserted into the inner cavity of the longitudinal cylinder 61, the shear wall body 1 gradually comes into contact with the ground, driving the guide cylinder 6501 to rise into the cone cavity 6102, completing the contact operation between the shear wall body 1 and the ground. Finally, grout is injected into the inner cavities of the longitudinal cylinder 61 and the transverse cylinder 62 through the grouting input pipe 63 using external grouting equipment, so that the reinforcing bar 8 is connected with the secondary structural transverse reinforcing bar 3 and the secondary structural longitudinal reinforcing bar 5, forming a stable and firm connection.
