[0002] Reinforced concrete (also known as steel-concrete or reinforced steel-reinforced concrete) composite structural components are composed of concrete, steel sections, longitudinal reinforcement, and stirrups. Reinforced concrete structures can be divided into those where all structural components are reinforced concrete and those where only some are. Reinforced concrete offers advantages such as high strength, small cross-sectional dimensions, strong bond strength with concrete, concrete conservation, increased usable space, reduced project costs, and improved project quality. The presence of steel structures significantly improves the ductility of components, resulting in strong deformation resistance, excellent seismic performance, and high bearing capacity.

DETAILED DESCRIPTION

[0018] In the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish between protective components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] Example 1: Please refer to Figure 1A device for quickly positioning and clamping steel bars at a rigid concrete beam-column node comprises a pillar 1, wherein each pillar 1 is connected by a steel bar 2, a first clamping assembly 3 is arranged between the steel bar 2 and the pillar 1, and the first clamping assembly 3 is used to fix the steel bar 2 and the pillar 1, and different steel bars 2 are connected by a second clamping assembly 4, and the second clamping assembly 4 is used to position steel bars 2 in the coaxial direction, and the second clamping assembly 4 is used to fix steel bars 2 in different axial directions.

[0020] The working principle and beneficial effects of the above scheme: The present application provides a first clamping assembly 3 to fix the support 1 and the steel bar 2, and a second clamping assembly 4 to fix different steel bars 2 together, thereby eliminating the need for welding the support 1 and the steel bar 2 at the node, thereby solving the problem of inconvenience in welding due to the complex structure of the node. Moreover, since the first clamping assembly 3 can be provided in advance, the steel bar 2 can be directly fixed to the first clamping assembly 3, which can effectively avoid the problem of difficulty in accurately positioning the steel bar. In some cases, the steel bars 2 between the two groups of pillars 1 need to be welded in position. When the two ends of the steel bars are not aligned accurately, it is easy to cause poor welding effect. The second clamping component 4 is used to accurately connect the two ends of the steel bars 2 to ensure the welding effect.

[0021] Example 2: Please refer to Figure 2-Figure 7 On the basis of Example 1, the first clamping assembly 3 includes a fixed plate 5, the fixed plate 5 is fixedly connected to the pillar 1, a fixed head 6 is provided on the fixed plate 5, a gripper 7 is clamped on the outer periphery of the fixed head 6, a clamping member 11 is provided on the inner side of the gripper 7, and a steel bar 2 is clamped between the clamping member 11 and the fixed head 6.

[0022] An arc-shaped groove is provided on a side of the fixing head 6 facing the clamping member 11 .

[0023] The clamping members 11 are symmetrically arranged in two groups. A fixed slide rod 24 is fixedly connected to the side of the clamping member 11. The fixed slide rod 24 is inserted into the gripper 7. The gripper 7 is fixedly connected to a driving rod 26. An adjusting disk 8 is provided on the side of the gripper 7 away from the fixed head 6, and a driving cover 9 is rotatably connected to the adjusting disk 8; The adjusting disk 8 is provided with a second slide groove 16, and the second slide groove 16 is a linear slide groove; The driving cover 9 is provided with a first slide groove 12, and the first slide groove 12 is an arc slide groove; The driving rod 26 is slidably connected to the second sliding groove 16 , and the driving rod 26 passes through the second sliding groove 16 . The end of the driving rod 26 is slidably connected to the first sliding groove 12 .

[0024] A second communication hole 17 is provided at the center of the adjusting disk 8, the side wall of the second communication hole 17 extends beyond the surface of the adjusting disk 8, and a latching tooth 18 is provided on the side wall of the second communication hole 17; The latch teeth 18 are preferably ratchet wheels; A first connecting hole 13 is provided at the center of the driving cover 9. An elastic block 14 is provided on the side of the first connecting hole 13. The elastic block 14 can be engaged with the latching teeth 18. The side of the adjusting disk 8 is provided with a connecting plate 20, and the connecting plate 20 is provided with two groups. An empty slot 19 is provided between the two groups of the connecting plates 20, and a card slot 21 is provided on the connecting plate 20; Two groups of limit blocks 15 are provided on the inner side of the edge of the driving cover 9 , and the limit blocks 15 are slidably engaged in the card slots 21 .

[0025] The adjusting disk 8 is provided with a slider 22 on the side facing the gripper 7, and the slider 22 is located on both sides of the second chute 16; The gripper 7 is provided with a moving groove 25 , and the slider 22 is slidably connected in the moving groove 25 .

[0026] A connecting piece 10 is provided on one side of the driving cover 9, and a bolt is fixedly connected to the connecting piece 10. A fixing groove 23 is provided in the second connecting hole 17, and a nut is provided in the fixing groove 23. The bolt passes through the first connecting hole 13 and is threadedly connected to the nut.

[0027] The working principle and beneficial effects of the above scheme: When the pillar 1 and the steel bar 2 are fixed by the first clamping assembly 3, the first clamping assembly 3 pre-set on the pillar 1 can effectively solve the positioning problem of the steel bar 2; When fixing the steel bar 2, the steel bar 2 is placed in the arc groove of the fixed head 6 fixed to the pillar 1, and the driving cover 9 is rotated. The driving rod 26 is driven to move by the first slide groove 12 in the driving cover 9. The driving rod 26 is restricted by the first slide groove 12 and the second slide groove 16. During the relative rotation of the adjusting disk 8 and the driving cover 9, the overlapping position of the first slide groove 12 and the second slide groove 16 changes, driving the driving rod 26 to move toward the center of the adjusting disk 8 and the driving cover 9. The driving rod 26 drives the two sets of grippers 7 to move toward each other, holding the fixed head 6 tightly, and in this process, the clamping member 11 fixed on the gripper 7 moves accordingly, clamping the steel bar 2 stably, completing the relative fixation of the pillar 1 and the steel bar 2. During the relative rotation of the adjusting disk 8 and the driving cover 9, the elastic block 14 and the latching tooth 18 also move relatively unidirectionally, which can prevent the fixation of the pillar 1 and the steel bar 2 from loosening when the driving cover 9 loses external force; The arrangement of the connecting plate 20 makes the relative rotation between the adjusting disk 8 and the driving cover more stable, and the card slot 21 provided on the connecting plate 20 cooperates with the limit card block 15 to further increase the stability of the relative rotation between the adjusting disk 8 and the driving cover; The provision of the first clamping assembly 3 avoids the welding operation of the pillar 1 and the steel bar 2. Compared with welding fixation, it reduces the difficulty of fixation and increases efficiency while maintaining a firm fixation.

[0028] Example 3: Please refer to Figures 8-13 , based on Example 1, the second clamping assembly 4 includes a first fixing member 27 and a second fixing member 33, and the first fixing member 27 and the second fixing member 33 are connected by a fastening screw 37; The first fixing member 27 and the second fixing member 33 are both U-shaped; The bending parts of the first fixing member 27 and the second fixing member 33 are both made of flexible material; The first fixing member 27 is provided with a first fixing block 28 and a second fixing block 29 at both ends thereof. A positioning groove 30 is provided on the opposite side of the first fixing block 28 and the second fixing block 29. The positioning groove 30 is used to clamp the positioning rod. The positioning rod is preferably a rigid straight rod; The first connecting groove 31 is provided at the bending portion of the first fixing member 27, and the first connecting groove 31 is used to clamp the steel bar 2 to be positioned; A second connecting groove 35 is provided at the bending portion of the second fixing member 33 , and the second connecting groove 35 is used to clamp the fixed steel bar 2 .

[0029] The first fixing member 27 is fixedly connected to a first adjusting block 32; The second fixing member 33 is fixedly connected to a second adjusting block 34 , and the second adjusting block 34 is fixedly connected to a connecting piece 38 , and the connecting piece 38 is rotatably inserted into the first fastening hole 42 ; The first adjustment block 32 and the second adjustment block 34 are both provided with latching teeth on the opposite sides thereof, and the latching teeth on the first adjustment block 32 and the second adjustment block 34 can mesh with each other; The first fixing member 27 is provided with a second alignment strip 41; A first alignment strip 39 is provided on the second fixing member 33 .

[0030] The first fixing member 27 is provided with a second fastening hole 43, the first adjusting block 32 is provided with a first fastening hole 42, the fastening screw 37 passes through the first fastening hole 42, the second fastening hole 43, the second adjusting block 34 and is connected to the second fixing member 33; One end of the fastening screw 37 is fixedly connected to the fastening screw 36; A limiting piece 40 is provided on the fastening screw 37 .

[0031] The working principle and beneficial effects of the above scheme: In some cases, the steel bar 2 needs to be welded in position. When the two ends of the steel bar are not aligned accurately, it is easy to cause poor welding effect. The second clamping component 4 is used to accurately connect the two ends of the steel bar 2 to ensure the welding effect.

[0032] When welding different steel bars 2 in position, a group of second clamping components 4 can be first fixed to the other steel bars 2 that have been firmly fixed, that is, the second fixing piece 33 can be sleeved on the steel bars 2 that have been firmly fixed, and different first fixing pieces 27 can be sleeved on the two groups of steel bars 2 to be aligned, and the first connecting groove 31 and the second connecting groove 35 can be tightened by tightening the tightening screw 37. In this process, the positioning grooves 30 of the two different first fixing pieces 27 hold the same group of positioning rods. By rotating the first fixing piece 27 and the second fixing piece 33, the angle between the steel bars 2 to be fixed and the already firmly fixed steel bars 2 is changed, so that the positioning grooves 30 of the two different first fixing pieces 27 can stably clamp the same group of positioning rods. At this time, the two groups of steel bars 2 to be aligned clamped by the different first fixing pieces 27 are in the same straight line, that is, the alignment and pre-fixation of the two groups of steel bars 2 are completed, and waiting for welding; The locking teeth on the first adjusting block 32 and the second adjusting block 34 can prevent the first adjusting block 32 and the second adjusting block 34 from rotating relative to each other after the fastening screw 37 is tightened, thereby maintaining the alignment and stability of the steel bar 2 to be welded; When two sets of second clamping assemblies 4 are arranged on the same firmly fixed steel bar 2 or on firmly fixed steel bars 2 with a determined positional relationship, the first alignment bar 39 and the second alignment bar 41 can ensure that construction personnel can accurately determine the deflection angle and the alignment angle.
