Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of structural engineering, and particularly relates to a quickly-installed fabricated concrete structure beam-column joint and a construction method thereof. BACKGROUND

[0002] Fabricated building is a modern building method, which transfers a large number of on-site operations in traditional building construction to factories. The fabricated concrete structure beam-column joint is a key part of the fabricated building, which is mainly responsible for bearing and transmitting loads. The joint is usually composed of a precast beam, a precast column and a connecting piece, and is completed by on-site assembly and pouring of concrete. The design of the fabricated concrete structure beam-column joint needs to consider the structural strength, stability and durability, as well as the construction convenience and economy. During the construction process, the design requirements and construction specifications need to be strictly followed to ensure the quality and safety of the joint.

[0003] In the existing construction method, the beam and column are prefabricated, the precast column is accurately placed on the foundation according to the design position, and temporary fixing measures are taken to ensure the position unchanged. The precast beam is hoisted to the design position by using a lifting machine, and is connected with the precast column or other beams. The connecting holes are reserved on the contact surface of the beam and column, or the reserved steel bars are used for joint connection. The beam and column are firmly connected together by using bolts, welding or other connection methods. Finally, the concrete is injected into the reserved holes of the beam-column connection part to form an integral connection. Compared with the traditional building method, the fabricated building method is more efficient, environmentally friendly, reduces the demand for manpower and reduces the cost. However, when the precast beam is hoisted to the design position by using the lifting machine, the position of the column and the beam needs to be accurately placed to ensure the pouring effect. The lifting machine needs to be repeatedly corrected in position, which causes complicated construction operation, low efficiency and easy position deviation, and affects the subsequent pouring connection. Therefore, the present application proposes a quickly-installed fabricated concrete structure beam-column joint and a construction method thereof. SUMMARY

[0004] In order to make up for the deficiencies of the prior art, solve the problem that when the precast beam is hoisted to the design position by using the lifting machine, the position of the column and the beam needs to be accurately placed to ensure the pouring effect, the lifting machine needs to be repeatedly corrected in position, which causes complicated construction operation, low efficiency and easy position deviation, and affects the subsequent pouring connection, the present application proposes a quickly-installed fabricated concrete structure beam-column joint and a construction method thereof.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A quick-installation prefabricated concrete structure beam-column joint and its construction method, comprising a column; a connecting block is fixedly installed on one side of the column, a reinforcing bar column is fixedly installed on the top of the connecting block, a crossbeam is installed on one side of the reinforcing bar column, a reinforcing bar ring is fixedly installed on the side of the crossbeam near the reinforcing bar column, and a correction component is provided at the top of the crossbeam; by setting the correction component and the fixing component, when positioning the component, the crane is operated to move the crossbeam above the connecting block, and the position of the crossbeam is corrected by the correction component and the fixing component, and then the crane is operated to move the crossbeam downwards to complete the component positioning. This avoids the problem that when using crane machinery to hoist the precast beam to the design position, in order to ensure the pouring effect, the positions of the column and the crossbeam need to be precisely placed, requiring the crane to repeatedly correct the position, resulting in cumbersome construction operations, low efficiency, and easy positional deviations that affect subsequent pouring connections. This makes the correction of the crossbeam position simpler, faster, and more accurate.

[0006] Preferably, the calibration assembly includes a connecting plate, a calibration column, a first calibration groove, a second calibration groove, a first push block, a handle connection port, a lead screw, a first calibration plate, a second push block, an auxiliary rod, a first rack, a gear, a second rack, and a second calibration block. A connecting plate is fixedly installed at the top of the crossbeam, and a calibration column is fixedly installed at the bottom of the connecting plate. The calibration column is slidably installed on the inner wall of the first calibration groove. The first calibration groove is located at the top of the connecting block, and a second calibration groove is located at the bottom of the first calibration groove. A first push block is slidably installed on one side of the connecting plate, and a handle connection port is installed on the inner wall of the first push block. A lead screw is located at the end of the handle connection port away from the connecting plate. The handle connector is rotatably mounted on the outer wall of the connecting plate. A first correction plate is fixedly mounted on the bottom of the first push block. A pouring port is installed on one side of the first correction plate. Second push blocks are symmetrically mounted on both sides of the first push block. Each second push block is fixedly mounted on the top of the first correction plate. A reinforcing component is provided on one side of the second push block near the column. An auxiliary rod is installed on the inner wall of each second push block. The end of the auxiliary rod near the connecting plate is fixedly mounted on the outer wall of the connecting plate. A first rack is fixedly mounted on the top of the first correction plate. A gear is meshed on one side of the first rack. A fixing component is provided on the side of the first rack away from the gear. The gear is meshed with a second rack on the side away from the first rack, and a second alignment block is fixedly installed on the end of the second rack away from the gear. By setting up the alignment assembly, when the precast beam is hoisted to the design position using lifting machinery, the operator moves the crossbeam above the connecting block and pushes the crossbeam to adjust the position of the alignment column, so that the alignment column is above the first alignment groove. The operator then moves the alignment column downwards to the inner wall of the first alignment groove. At this time, the operator inserts the rotating handle into the inner wall of the lead screw, connecting the handle to the handle connection port. Rotating the handle drives the lead screw to rotate, which in turn drives the first push block to move closer to the connecting plate. The first push block then drives the first alignment plate to move, and the first alignment plate... The auxiliary rod moves with the first rack, which in turn drives the gear to rotate. This causes the gear to move the second rack closer to the gear, which in turn moves the second correction block. This causes the first correction plate and the second correction block to abut against the sides of the connecting block, making the crossbeam perpendicular to the column. This completes the correction of the crossbeam's position. Then, the crane is operated to move the correction column downwards to the inner wall of the second correction groove, completing the component positioning. This avoids the problem of cumbersome and inefficient construction operations caused by the need for repeated position corrections of the crane when using cranes to lift precast beams to the design position in order to ensure the pouring effect. This makes the crossbeam position correction simpler and improves construction efficiency.

[0007] Preferably, the distance between the two ends of the first correction groove is greater than the distance between the two sides of the correction column. By setting the distance between the two ends of the first correction groove to be greater than the distance between the two sides of the correction column, it is easier to place the correction column on the inner wall of the first correction groove. This avoids the problem of workers having to push a heavy crossbeam to repeatedly correct the position when the distance between the two ends of the first correction groove is the same as the distance between the two sides of the correction column, so as to place the correction column on the inner wall of the first correction groove, which causes cumbersome and inconvenient construction. This makes the correction steps simpler.

[0008] Preferably, the fixing component includes a first limiting groove, a torsion spring column, a rotating toothed block, and a fixed toothed block. The first limiting groove is evenly distributed on the side of the first rack away from the gear. A torsion spring column is installed on the inner wall of each first limiting groove, and a rotating toothed block is installed on the outer wall of each torsion spring column. A fixed toothed block is installed on the side of each rotating toothed block away from the first rack, and the fixed toothed block is fixedly installed on the inner wall of the connecting plate. By setting the fixing component, when the correction component corrects the crossbeam, the first rack drives the rotating toothed block to move. The rotating toothed block is squeezed by the fixed toothed block and rotates towards the first limiting groove. When the fixed toothed block stops squeezing the rotating toothed block, the torsion spring column releases its pressure. The elastic potential energy is released, and the torsion spring column drives the rotating toothed block to rotate away from the first limiting groove. When the first rack moves away from the gear, the gear drives the rotating toothed block to move, so that the rotating toothed block abuts against the fixed toothed block. The fixed toothed block hinders the movement of the rotating toothed block, thereby hindering the movement of the correction assembly. This avoids the problem that when the correction assembly corrects the crossbeam, the crossbeam swings left and right due to inertia, causing the first correction plate and the second correction block to continuously squeeze the connecting block, causing the first correction plate and the second correction block to move away from the gear, thus affecting the correction process. This ensures that the first correction plate and the second correction block will not move away from the gear, making the correction process of the correction assembly more stable.

[0009] Preferably, the rotation range of the rotating tooth block within the inner wall of the first limiting groove is 90 degrees. By setting the rotation range of the rotating tooth block within the inner wall of the first limiting groove to 90 degrees, when the first correction plate moves away from the gear, the rotating tooth block abuts against the fixed tooth block. At this time, the first limiting groove limits the rotating tooth block, preventing it from continuing to rotate, thereby achieving the obstruction effect on the first correction plate.

[0010] Preferably, the rotating tooth block abuts against the fixed tooth block; by setting the rotating tooth block to abut against the fixed tooth block when the correction component completes the correction, the rotating tooth block prevents the first correction plate from moving away from the gear after the correction component completes the correction, so that the position of the crossbeam will not move, avoiding the crossbeam from still being able to move slightly after the correction is completed, which would reduce the correction effect and affect the effect of the casting connection. This ensures that the crossbeam does not move after the position correction is completed, thereby improving the casting effect.

[0011] Preferably, the reinforcing assembly includes a first limiting plate, a second limiting groove, a second limiting plate, a push rod, a first sliding groove, a first spring, a reinforcing shell, a reinforcing block, a second spring, a support plate, a second sliding groove, and a third sliding groove. A first limiting plate is fixedly installed on one side of the second push block near the column. Second limiting grooves are evenly distributed at the bottom end of the first limiting plate. Second limiting plates are slidably installed on the inner wall of the second limiting grooves. Push rods are fixedly installed at the bottom end of each of the second limiting plates, and each push rod is slidably installed on the inner wall of the first sliding groove. The first sliding groove is located on the side of the connecting plate near the column. A first spring is installed at the end of the push rod near the connecting plate. The end of the first spring away from the push rod is installed on the inner wall of the first sliding groove. A reinforcing shell is fixedly installed at the end of the push rod away from the first spring. Reinforcing blocks are symmetrically installed on the inner wall of the reinforcing shell. Limiting components are provided between the reinforcing blocks. A second spring is installed on one side of each reinforcing block. A support plate is installed at the end of the second spring away from the reinforcing block. The support plates are fixedly installed on the inner wall of the reinforcing shell. The reinforcing shell is slidably installed on the inner wall of the second sliding groove. The second sliding groove is located at the top of the connecting block. Third sliding grooves are provided on both sides of the bottom of the second sliding groove. By setting the reinforcing components, when the correction component corrects the position of the crossbeam, the second push block near the column drives the first limiting plate to move. The first limiting plate drives the second limiting groove to move, so that the second limiting groove is located on one side of the second limiting plate, thereby stopping the first limiting plate from limiting the second limiting plate. At this time, the first spring releases its elastic potential energy, pushing the push rod away from the column. The first spring moves, and the push rod drives the reinforcing shell to move, so that the reinforcing shell abuts against the side of the column near the crossbeam. After the position is corrected, the crane drives the crossbeam to move closer to the connecting block, and at the same time drives the reinforcing shell to move. The reinforcing shell moves to the inner wall of the second sliding groove. When the reinforcing shell moves to the bottom of the second sliding groove, the second spring releases its elastic potential energy, pushing the reinforcing block to move away from the reinforcing shell, so that the reinforcing block moves to the inner wall of the third sliding groove, completing the reinforcement of the connection point between the column and the crossbeam, making the beam-column joint more solid and improving the service life of the beam and column.

[0012] Preferably, the distance between the two sides of the second push block is equal to the distance between the second limiting groove and the second limiting plate. By setting the distance between the two sides of the second push block to be equal to the distance between the second limiting groove and the second limiting plate before the correction component operates, the second limiting groove moves to one side of the second limiting plate when the correction is completed. This allows the reinforcement component to start after the correction component completes the correction, avoiding the problem that when the correction component is performing correction, the reinforcement shell moves to abut against one side of the column, causing the reinforcement shell to not fit against the side of the column, thus affecting the rotation of the crossbeam and consequently affecting the operation of the correction component.

[0013] Preferably, the limiting component includes a limiting block and a protrusion. The limiting block is installed between the reinforcing blocks, and a protrusion is installed at the bottom end of the limiting block. The protrusion is fixedly installed at the top end of the connecting block. By setting the limiting component, before the reinforcing component operates, the limiting block abuts against the reinforcing block, preventing the reinforcing block from moving. When the reinforcing shell moves to the bottom of the second sliding groove, the limiting block pushes the second sliding groove to move, causing the second sliding groove to stop limiting the reinforcing block. This allows the reinforcing component to complete its reinforcing function, avoiding the problem that the reinforcing block moves away from the second spring due to the release of elastic potential energy by the second spring before the reinforcing component operates, preventing the reinforcing shell from moving on the inner wall of the second sliding groove and causing the reinforcing component to malfunction. This ensures that the reinforcing block can remain on the inner wall of the reinforcing shell before the reinforcing component operates.

[0014] A construction method for rapidly installing prefabricated concrete beam-column joints includes the following steps:

[0015] Step 1: Prefabricate the column and connecting block. The column and connecting block are prefabricated as one piece. The connecting block is located on the side of the column. A first correction groove, a second correction groove, a second sliding groove and a third sliding groove are opened on the top of the connecting block. A steel column is installed on the top of the connecting block.

[0016] Step 2: Precast beams and connecting plates, install steel rings at the ends of the beams, install straightening columns at the bottom of the connecting plates, install straightening and fixing components on the inner wall of the connecting plates, and install reinforcement components on the side of the connecting plates near the ends of the beams.

[0017] Step 3: On-site installation. Fix the column in the preset position. Use a crane to move the crossbeam above the connecting block and push the crossbeam to adjust the position of the correction column so that the correction column is above the first correction groove. Operate the crane to move the correction column down to the inner wall of the first correction groove. At this time, the worker inserts the handle into the inner wall of the screw rod to connect the handle with the handle connection port. Turn the handle to drive the screw rod to rotate. The screw rod drives the first push block to move closer to the connecting plate. The first push block drives the first correction plate to move. The first correction plate drives the auxiliary rod and the first rack to move. The first rack then drives the gear to rotate, so that the gear drives the second rack to move closer to the gear. The second rack drives the second correction block to move, so that the first correction plate and the second correction block abut against the two sides of the connecting block, making the crossbeam perpendicular to the column, completing the correction of the crossbeam position. Then operate the crane to move the correction column down to the inner wall of the second correction groove to complete the component positioning. At the same time, the reinforcement component operates automatically to reinforce the beam-column joint.

[0018] Step 4: Pour concrete through the pouring port set on one side of the first correction plate to complete the connection of the beam-column joint.

[0019] The advantages of this invention are:

[0020] 1. This invention, by setting up a correction component, allows for the following process: When a precast beam is hoisted to its designed position using lifting machinery, the operator moves the crossbeam above the connecting block and pushes the crossbeam to adjust the position of the correction column, positioning it above the first correction groove. The operator then moves the correction column downwards to the inner wall of the first correction groove. At this point, the operator inserts a rotating handle into the inner wall of the lead screw, connecting the handle to the handle connector. Rotating the handle causes the lead screw to rotate, which in turn moves the first push block closer to the connecting plate. The first push block moves the first correction plate, which in turn moves the auxiliary rod and the first rack. The first rack then drives the gear to rotate, causing the gear to drive the second rack... The first rack moves towards the gear, and the second rack drives the second correction block to move, so that the first correction plate and the second correction block abut against the two sides of the connecting block, making the crossbeam perpendicular to the column, thus completing the correction of the crossbeam position. Then, the crane is operated to move the correction column downward to the inner wall of the second correction groove, thus completing the component positioning. This avoids the problem that when using cranes to hoist the precast beam to the design position, in order to ensure the pouring effect, the position of the column and the crossbeam needs to be precisely placed, requiring the crane to repeatedly correct the position, which makes the construction operation cumbersome, inefficient, and prone to crossbeam position deviation, affecting the subsequent pouring connection. This makes the crossbeam position correction simpler and improves the construction efficiency.

[0021] 2. By setting a fixed component, when the correction component corrects the crossbeam, the first rack drives the rotating toothed block to move. The rotating toothed block is squeezed by the fixed toothed block and rotates towards the first limiting groove. When the fixed toothed block stops squeezing the rotating toothed block, the torsion spring column releases elastic potential energy, and the torsion spring column drives the rotating toothed block to rotate away from the first limiting groove. When the first rack moves away from the gear, the gear drives the rotating toothed block to move, so that the rotating toothed block abuts against the fixed toothed block. The fixed toothed block hinders the movement of the rotating toothed block, thereby hindering the movement of the correction component. This avoids the problem that when the correction component corrects the crossbeam, the crossbeam swings left and right due to inertia, causing the first correction plate and the second correction block to continuously squeeze the connecting block, causing the first correction plate and the second correction block to move away from the gear, affecting the correction process. This invention prevents the first correction plate and the second correction block from moving away from the gear, making the correction process of the correction component more stable.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figures 1-8As shown, a quick-installation prefabricated concrete beam-column joint includes a column 1; a connecting block 2 is fixedly installed on one side of the column 1, a reinforcing bar column 3 is fixedly installed on the top of the connecting block 2, a crossbeam 4 is installed on one side of the reinforcing bar column 3, a reinforcing bar ring 5 is fixedly installed on the side of the crossbeam 4 near the reinforcing bar column 3, and a correction component is set on the top of the crossbeam 4; by setting the correction component and the fixing component, when positioning the component, the crane is operated to move the crossbeam 4 above the connecting block 2, and the position of the crossbeam 4 is corrected by the correction component and the fixing component, and then the crane is operated to move the crossbeam 4 downward to complete the component positioning. This avoids the problem that when using cranes to lift precast beams to the design position, in order to ensure the pouring effect, the positions of the column 1 and the crossbeam 4 need to be precisely placed, requiring the crane to repeatedly correct the position, which makes the construction operation cumbersome, inefficient, and prone to positional deviation, affecting the subsequent pouring connection. This makes the correction of the position of the crossbeam 4 simpler and faster, and makes the correction of the position of the crossbeam 4 more accurate.

[0035] Please see Figures 1-3 and Figure 5As shown, the calibration assembly includes a connecting plate 6, a calibration column 7, a first calibration groove 8, a second calibration groove 9, a first push block 10, a handle connection port 11, a lead screw 12, a first calibration plate 13, a second push block 14, an auxiliary rod 15, a first rack 16, a gear 17, a second rack 18, and a second calibration block 19. The connecting plate 6 is fixedly installed at the top of the crossbeam 4, and the calibration column 7 is fixedly installed at the bottom of the connecting plate 6. The calibration column 7 is slidably installed on the inner wall of the first calibration groove 8. The first calibration groove 8 is located at the top of the connecting block 2, and the second calibration groove 9 is located at the bottom of the first calibration groove 8. The first push block 10 is slidably installed on one side of the connecting plate 6, and the handle connection port 11 is installed on the inner wall of the first push block 10. A lead screw 12 is located at the end of the handle connection port 11 away from the connecting plate 6, and the other end of the handle connection port 11 is rotatably installed on the outer side of the connecting plate 6. The wall has a first correction plate 13 fixedly installed at the bottom of the first push block 10. A pouring port is installed on one side of the first correction plate 13. Second push blocks 14 are symmetrically installed on both sides of the first push block 10. The second push blocks 14 are all fixedly installed at the top of the first correction plate 13. A reinforcing component is provided on one side of the second push block 14 near the column 1. An auxiliary rod 15 is installed on the inner wall of the second push block 14. The end of the auxiliary rod 15 near the connecting plate 6 is fixedly installed on the outer wall of the connecting plate 6. A first rack 16 is fixedly installed at the top of the first correction plate 13. A gear 17 is meshed on one side of the first rack 16. A fixing component is provided on the side of the first rack 16 away from the gear 17. A second rack 18 is meshed on the side of the gear 17 away from the first rack 16. A second correction block 19 is fixedly installed on the end of the second rack 18 away from the gear 17.By setting up the correction components, when the precast beam is hoisted to the design position using lifting machinery, the operator moves the crossbeam 4 above the connecting block 2 and pushes the crossbeam 4 to adjust the position of the correction column 7, so that the correction column 7 is above the first correction groove 8. The operator then moves the correction column 7 downward to the inner wall of the first correction groove 8. At this time, the operator inserts the rotating handle into the inner wall of the lead screw 12, so that the handle is connected to the handle connection port 11. Rotating the handle drives the lead screw 12 to rotate. The lead screw 12 drives the first push block 10 to move closer to the connecting plate 6. The first push block 10 drives the first correction plate 13 to move. The first correction plate 13 drives the auxiliary rod 15 and the first rack 16 to move. The first rack 16 then drives the gear 17 to rotate, so that the gear 17 drives... The second rack 18 moves closer to the gear 17, causing the second correction block 19 to move. This causes the first correction plate 13 and the second correction block 19 to abut against both sides of the connecting block 2, making the crossbeam 4 perpendicular to the column 1. This completes the correction of the crossbeam 4's position. Then, the crane is operated to move the correction column 7 downwards to the inner wall of the second correction groove 9, completing the component positioning. This avoids the need for precise placement of the column 1 and crossbeam 4 when using cranes to lift the precast beam to the design position, requiring repeated position corrections by the crane to ensure the pouring effect. This process is cumbersome, inefficient, and prone to causing crossbeam 4 positional deviations, affecting subsequent pouring connections. The crossbeam 4 position correction is now simpler, improving construction efficiency.

[0036] Please see Figure 1 , Figure 5 and Figure 6 As shown, the distance between the two ends of the first correction groove 8 is greater than the distance between the two sides of the correction column 7. By setting the distance between the two ends of the first correction groove 8 to be greater than the distance between the two sides of the correction column 7, it is easier to place the correction column 7 on the inner wall of the first correction groove 8. This avoids the problem of cumbersome and inconvenient construction caused by the need for workers to push the heavy crossbeam 4 to repeatedly correct the position when the distance between the two ends of the first correction groove 8 is the same as the distance between the two sides of the correction column 7, so that the correction column 7 is placed on the inner wall of the first correction groove 8. This makes the correction steps simpler.

[0037] Please see Figure 2 , Figure 3 and Figure 5As shown, the fixing assembly includes a first limiting groove 20, a torsion spring column 21, a rotating toothed block 22, and a fixed toothed block 23. The first limiting groove 20 is evenly distributed on the side of the first rack 16 away from the gear 17. Torsion spring columns 21 are installed on the inner walls of the first limiting groove 20, and rotating toothed blocks 22 are installed on the outer walls of the torsion spring columns 21. Fixed toothed blocks 23 are installed on the side of the rotating toothed blocks 22 away from the first rack 16, and the fixed toothed blocks 23 are fixedly installed on the inner wall of the connecting plate 6. By setting up the fixing assembly, when the correction assembly corrects the crossbeam 4, the first rack 16 drives the rotating toothed blocks 22 to move. The rotating toothed blocks 22 are squeezed by the fixed toothed blocks 23 and rotate towards the first limiting groove 20. When the fixed toothed blocks 23 stop squeezing the rotating toothed blocks 22, the torsion spring column 21 releases its elastic potential. Yes, the torsion spring column 21 drives the rotating toothed block 22 to rotate away from the first limiting groove 20. When the first rack 16 moves away from the gear 17, the gear 17 drives the rotating toothed block 22 to move, so that the rotating toothed block 22 abuts against the fixed toothed block 23, and the fixed toothed block 23 hinders the movement of the rotating toothed block 22. Thus, the rotating toothed block 22 hinders the movement of the correction assembly, avoiding the problem that when the correction assembly corrects the crossbeam 4, the crossbeam 4 swings left and right due to inertia, causing the first correction plate 13 and the second correction block 19 to continuously press against the connecting block 2, causing the first correction plate 13 and the second correction block 19 to move away from the gear 17, affecting the correction process. This ensures that the first correction plate 13 and the second correction block 19 will not move away from the gear 17, making the correction process of the correction assembly more stable.

[0038] Please see Figure 2 , Figure 3 and Figure 5 As shown, the rotation range of the rotating tooth block 22 on the inner wall of the first limiting groove 20 is 90 degrees. By setting the rotation range of the rotating tooth block 22 on the inner wall of the first limiting groove 20 to 90 degrees, when the first correction plate 13 moves away from the gear 17, the rotating tooth block 22 abuts against the fixed tooth block 23. At this time, the first limiting groove 20 limits the rotating tooth block 22, so that the rotating tooth block 22 will not continue to rotate, thereby achieving the obstruction effect on the first correction plate 13.

[0039] Please see Figure 2 , Figure 3 and Figure 5 As shown, the rotating tooth block 22 abuts against the fixed tooth block 23. By setting the rotating tooth block 22 to abut against the fixed tooth block 23 when the correction component completes the correction, the rotating tooth block 22 prevents the first correction plate 13 from moving away from the gear 17 after the correction component completes the correction. This prevents the position of the crossbeam 4 from moving, thus avoiding the crossbeam 4 from moving slightly after the correction is completed, which would reduce the correction effect and affect the casting connection effect. This ensures that the crossbeam 4 does not move after the position correction is completed, thereby improving the casting effect.

[0040] A construction method for rapidly installing prefabricated concrete beam-column joints includes the following steps:

[0041] Step 1: Prefabricate column 1 and connecting block 2. Prefabricate column 1 and connecting block 2 as one piece. Connecting block 2 is located on the side of column 1. A first correction groove 8, a second correction groove 9, a second sliding groove 34 and a third sliding groove 35 are opened on the top of connecting block 2. Reinforcing steel column 3 is installed on the top of connecting block 2.

[0042] Step 2: Precast crossbeam 4 and connecting plate 6, install steel ring 5 at the end of crossbeam 4, install correction column 7 at the bottom of connecting plate 6, install correction component and fixing component on the inner wall of connecting plate 6, and install reinforcement component on the side of connecting plate 6 near the end of crossbeam 4.

[0043] Step 3: On-site installation. Fix column 1 in the preset position. Use a crane to move crossbeam 4 above connecting block 2 and push crossbeam 4 to adjust the position of correction column 7 so that correction column 7 is above the first correction groove 8. Operate the crane to move correction column 7 down to the inner wall of the first correction groove 8. At this time, the worker inserts the handle into the inner wall of screw rod 12, so that the handle is connected to the handle connection port 11. Turn the handle to drive screw rod 12 to rotate. Screw rod 12 drives the first push block 10 to move closer to connecting plate 6. The first push block 10 drives the first correction plate 13 to move. The positive plate 13 drives the auxiliary rod 15 and the first rack 16 to move. The first rack 16 then drives the gear 17 to rotate, causing the gear 17 to drive the second rack 18 to move closer to the gear 17. The second rack 18 drives the second correction block 19 to move, so that the first correction plate 13 and the second correction block 19 abut against the two sides of the connecting block 2, making the crossbeam 4 perpendicular to the column 1, thus completing the correction of the position of the crossbeam 4. Then, the crane is operated to move the correction column 7 downward to the inner wall of the second correction groove 9, thus completing the component positioning. At the same time, the reinforcement component operates automatically to reinforce the beam-column joint.

[0044] Step 4: Pour concrete through the pouring port set on one side of the first correction plate 13 to complete the connection of the beam-column joint.

[0045] Example 2

[0046] Please see Figures 1-2 , Figures 4-8As shown in the comparison with Embodiment 1, as another embodiment of the present invention, the reinforcement component includes a first limiting plate 24, a second limiting groove 25, a second limiting plate 26, a push rod 27, a first sliding groove 28, a first spring 29, a reinforcement shell 30, a reinforcement block 31, a second spring 32, a support plate 33, a second sliding groove 34, and a third sliding groove 35. The first limiting plate 24 is fixedly installed on one side near the second push block 14 of the column 1. The bottom end of the first limiting plate 24 is evenly provided with second limiting grooves 25. The inner wall of the second limiting groove 25 is slidably installed with a second limiting plate 26. The bottom end of each second limiting plate 26 is fixedly installed with a push rod 27. All push rods 27 are slidably mounted on the inner wall of the first sliding groove 28. The first sliding groove 28 is opened on the side of the connecting plate 6 near the column 1. A first spring 29 is installed on the end of each push rod 27 near the connecting plate 6. The end of each first spring 29 away from the push rod 27 is installed on the inner wall of the first sliding groove 28. A reinforcing shell 30 is fixedly installed on the end of each push rod 27 away from the first spring 29. Reinforcing blocks 31 are symmetrically installed on the inner wall of each reinforcing shell 30. Limiting components are provided between the reinforcing blocks 31. A second spring 32 is installed on one side of each reinforcing block 31. A support plate 33 is installed on the end of each second spring 32 away from the reinforcing block 31. The support plates 33 are all fixed. Installed on the inner wall of the reinforced outer shell 30, the reinforced outer shell 30 is slidably installed on the inner wall of the second sliding groove 34. The second sliding groove 34 is opened at the top of the connecting block 2, and the bottom of the second sliding groove 34 is provided with a third sliding groove 35 on both sides. By setting the reinforcement component, when the correction component corrects the position of the crossbeam 4, the second push block 14 near the column 1 drives the first limiting plate 24 to move. The first limiting plate 24 drives the second limiting groove 25 to move, so that the second limiting groove 25 is located on one side of the second limiting plate 26, thereby stopping the first limiting plate 24 from limiting the second limiting plate 26. At this time, the first spring 29 releases elastic potential energy and pushes the push rod 27 away. The first spring 29 moves, and the push rod 27 drives the reinforced outer shell 30 to move, so that the reinforced outer shell 30 abuts against the side of the column 1 near the crossbeam 4. After the position is corrected, the crane drives the crossbeam 4 to move closer to the connecting block 2, and at the same time drives the reinforced outer shell 30 to move, so that the reinforced outer shell 30 moves to the inner wall of the second sliding groove 34. When the reinforced outer shell 30 moves to the bottom of the second sliding groove 34, the second spring 32 releases elastic potential energy, pushing the reinforced block 31 to move away from the reinforced outer shell 30, so that the reinforced block 31 moves to the inner wall of the third sliding groove 35, completing the reinforcement of the connection point between the column 1 and the crossbeam 4, making the beam-column joint more solid and improving the service life of the beam-column.

[0047] Please see Figure 2 and Figure 4As shown, the distance between the two sides of the second push block 14 is equal to the distance between the second limiting groove 25 and the second limiting plate 26. By setting the distance between the two sides of the second push block 14 and the distance between the second limiting groove 25 and the second limiting plate 26 to be equal before the correction component operates, the second limiting groove 25 moves to one side of the second limiting plate 26 when the correction is completed, so that the reinforcement component starts after the correction component completes the correction. This avoids the problem that when the correction component is performing correction, the reinforcement shell 30 moves to abut against one side of the column 1, so that the reinforcement shell 30 is not in contact with the side of the column 1, which affects the rotation of the crossbeam 4 and thus affects the operation of the correction component.

[0048] Please see Figures 6-8 As shown, the limiting component includes a limiting block 36 and a protrusion 37. The limiting block 36 is installed between the reinforcing blocks 31, and the protrusion 37 is installed at the bottom end of the limiting block 36. The protrusion 37 is fixedly installed at the top of the connecting block 2. By setting the limiting component, before the reinforcing component operates, the limiting block 36 abuts against the reinforcing block 31, preventing the reinforcing block 31 from moving. When the reinforcing shell 30 moves to the bottom of the second sliding groove 34, the limiting block 36 pushes the second sliding groove 34 to move, so that the second sliding groove 34 stops limiting the reinforcing block 31, allowing the reinforcing component to complete the reinforcing function. This avoids the problem that the reinforcing block 31 moves away from the second spring 32 due to the release of elastic potential energy by the second spring 32 before the reinforcing component operates, preventing the reinforcing shell 30 from moving on the inner wall of the second sliding groove 34 and causing the reinforcing component to not operate normally. This ensures that the reinforcing block 31 can remain on the inner wall of the reinforcing shell 30 before the reinforcing component operates.
