Description

Technical Field

[0001] This invention belongs to the field of auxiliary installation technology in building construction, and in particular relates to a positioning device for prefabricated columns in prefabricated frame structures. Background Technology

[0002] Currently, in the construction of precast columns, the reliable connection between the precast column and the precast column foundation is the core link in building the structural load-bearing skeleton. The prefabricated frame structure positioning device is a key auxiliary component for achieving precise docking between the two. It can guide the pre-embedded steel bars on the precast column foundation to be accurately aligned and inserted into the positioning holes at the bottom of the precast column, while limiting the gap between the positioning device and the precast column and the precast column foundation, thus creating a stable filling space for subsequent grouting operations, such as the prefabricated column positioning device for precast frame structures disclosed in announcement number CN219060927U. However, due to the slight displacement of the precast column foundation embedded steel bars during the pouring process caused by formwork offset and vibration, and the instability of the precast column posture due to the precision of the lifting equipment and the interference of the site environment, the existing positioning device cannot accurately guide the bottom of the precast column during hoisting, making it difficult to complete the insertion of the steel bars and positioning holes in one go. Construction personnel need to repeatedly adjust the horizontal position of the precast column. In addition, the existing positioning device cannot ensure the consistency of the gap between the positioning device and the precast column and the precast column foundation. Areas with excessively large gaps are prone to excessive accumulation of grout, forming local stress concentration points after solidification. Areas with excessively small gaps will hinder the flow of grout, forming dead corners, or even causing hollow areas due to insufficient penetration of grout.

[0003] To address this, a prefabricated column positioning device for prefabricated frame structures is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a prefabricated column positioning device for assembled frame structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated column positioning device for an assembled frame structure, comprising four positioning plates arranged in a rectangular splicing configuration, and further comprising: The first fixing mechanism is located between the opposite sides of two adjacent positioning plates, and the first fixing mechanism connects the four positioning plates into a whole. The sides of the four positioning plates are provided with grouting grooves. A guiding mechanism is provided at the top position of two adjacent positioning plates, and the guiding mechanism is used to guide the bottom of the hoisted precast column; A vibration mechanism is located below the four positioning plates, and the vibration end of the vibration mechanism extends to one side of the four positioning plates. Four slurry detection mechanisms are respectively installed inside the four positioning plates, and the detection parts on both sides of the slurry detection mechanism extend to the inside and outside of the positioning plate, respectively. The four slurry detection mechanisms correspond to the vibration end positions of the vibration mechanism. The slurry detection mechanisms are used to detect the overflow height of the slurry and the vibration intensity of the vibration mechanism. A PLC controller is located on one side of the positioning plate, and the vibration mechanism and the slurry detection mechanism are both electrically connected to the PLC controller.

[0006] Preferably, the first fixing mechanism includes a first fixing ring fixedly disposed on the side of two adjacent positioning plates, and a first bolt and a first nut that cooperate with each other are provided between the two adjacent first fixing rings.

[0007] Preferably, the guiding mechanism includes support rods fixedly disposed on the top of two adjacent positioning plates, and guide seats are fixedly disposed at the upper ends of the two support rods. The two guide seats are spliced ​​together at 90°, and the top of the two guide seats is provided with inclined guide grooves.

[0008] Preferably, the vibration mechanism includes four fixed plates arranged in a rectangular splice, with a second fixing mechanism between the opposite sides of each of the two adjacent fixed plates, a cylinder fixedly mounted on the outer side of each of the four fixed plates, an upwardly extending connecting plate fixedly mounted on the moving end of each of the four cylinders, a vibrating hammer fixedly mounted on the side of each of the four connecting plates facing the inside of the four fixed plates, and each of the four cylinders electrically connected to the PLC controller through an actuator and a feedback element.

[0009] Preferably, the second fixing mechanism includes a second fixing ring fixedly disposed on the side of the fixing plate, and a second bolt and a second nut that cooperate with each other are provided between two adjacent second fixing rings.

[0010] Preferably, the slurry detection mechanism includes a first detection groove disposed on the side wall of the grouting tank. A detection plate is slidably disposed at the opening of the first detection groove. A pressure sensor is fixedly disposed on the side of the detection plate facing the inside of the first detection groove. The pressure sensor is electrically connected to a PLC controller via a wire. A first spring is fixedly disposed on the side wall of the pressure sensor. Telescopic rods are fixedly disposed on the side wall of the detection plate on both sides of the pressure sensor. The end of the telescopic rod away from the detection plate is fixedly connected to the side wall of the first detection groove.

[0011] Preferably, a second detection groove is provided on the side of the positioning plate away from the first detection groove. A detection disk is slidably provided inside the second detection groove. A detection column extending into the first detection groove is fixedly provided on the side wall of the detection disk, and one end of the detection column is fixedly connected to one end of the first spring. A second spring is sleeved on the column wall of the detection column, and the two ends of the second spring are fixedly connected to the side wall of the detection disk and the side wall of the second detection groove, respectively.

[0012] Preferably, limiting blocks are fixedly provided on both sides of the detection plate, and limiting grooves that cooperate with the limiting blocks are provided on both sides of the first detection groove.

[0013] Compared with existing technologies, the advantages of this invention are as follows: 1. Through the grouting groove set on the positioning plate and the guide mechanism on the top of the positioning plate, the guide mechanism consists of a support rod and a guide seat. The four guide seats form a 90° angle after the positioning plate is spliced. The inclined guide groove on the top can guide the bottom of the hoisted precast column to move down smoothly, help adjust the posture of the precast column, and make the pre-embedded steel bars on the foundation accurately aligned with the positioning holes at the bottom of the precast column, so as to achieve one-time precise insertion. The grouting groove provides a channel for the flow of grout, and the distance between the grouting groove and the precast column is consistent, ensuring that the grout can flow smoothly into the connection part, laying the foundation for subsequent stable connection.

[0014] 2. The vibration mechanism consists of a fixed plate, cylinders, connecting plates, and vibrating hammers. The four cylinders are connected to the same air source through air pipes and are synchronously controlled by a PLC controller. When the cylinders retract, they drive the vibrating hammers to contact the detection discs on the positioning plates and apply hammering. The resulting vibration is transmitted to the positioning plates through the detection discs, causing the four positioning plates to vibrate uniformly at the same time. This synchronous vibration improves the fluidity of the grout inside the grouting tank, promotes the discharge of air bubbles, reduces dead corners in the filling, and ensures that the grout is evenly distributed and fully filled at the connection points.

[0015] 3. Through the set slurry detection mechanism, when the slurry is filled to the fullness of the connection part and begins to overflow, the overflowing slurry will accumulate in the grouting tank and contact the detection plate, pushing the detection plate to move and squeeze the pressure sensor. The PLC controller judges the amount of slurry based on the pressure change and issues an early warning. During the vibration, after the detection plate is hammered, the force is transmitted to the pressure sensor through the detection column. The PLC controller adjusts the cylinder action according to the pressure signal to ensure that each positioning plate is subjected to a uniform hammering force and achieves the best vibration effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] like Figures 1-5 As shown, a prefabricated column positioning device for an assembled frame structure includes four positioning plates 1 arranged in a rectangular splicing configuration, and also includes: The first fixing mechanism 2 is set between the opposite sides of two adjacent positioning plates 1, and the first fixing mechanism 2 connects the four positioning plates 1 into a whole. The sides of the four positioning plates 1 are provided with grouting grooves 3, which can provide gaps for grouting. At the same time, the distance between the grouting grooves 3 and the precast column is consistent, which improves the quality of grouting. The first fixing mechanism 2 includes a first fixing ring 21 fixedly set on the sides of two adjacent positioning plates 1. A first bolt 22 and a first nut 23 are provided between the two adjacent first fixing rings 21 to cooperate with each other, which can gradually form the four positioning plates 1 into an integral frame and fix it to the upper end of the precast column foundation.

[0020] The guide mechanism 4 is located at the top of two adjacent positioning plates 1 and is used to guide the bottom of the precast column being hoisted. The guide mechanism 4 includes a support rod 41 fixedly installed on the top of two adjacent positioning plates 1. The upper end of each of the two support rods 41 is fixedly provided with a guide seat 42. The two guide seats 42 are spliced ​​at 90° and the top of each of the two guide seats 42 is provided with an inclined guide groove 43. The included angle of the guide seat 42 is completely coincident with the included angle of the frame formed by splicing the four positioning plates 1, providing a unified benchmark for the subsequent hoisting guidance of the precast column.

[0021] The vibration mechanism 5 is located below the four positioning plates 1, and the vibration end of the vibration mechanism 5 extends to one side of the four positioning plates 1. The vibration mechanism 5 includes four rectangular spliced ​​fixed plates 51. A second fixing mechanism 52 is provided between the opposite sides of two adjacent fixed plates 51. The second fixing mechanism 52 includes a second fixing ring 521 fixedly set on the side of the fixed plate 51. A second bolt 522 and a second nut 523 are provided between two adjacent second fixing rings 521 to cooperate with each other, which can securely install the four fixed plates 51 on the four side walls of the precast column foundation. A cylinder 53 is fixedly provided on the outer side of each of the four fixed plates 51. A connecting plate 54 extending upward is fixedly provided on the moving end of each of the four cylinders 53. A vibrating hammer 55 is fixedly provided on the side of each of the four connecting plates 54 facing the inside of the four fixed plates 51. The vibrating hammer 55 is a solid metal hammer. When the cylinder 53 performs the retraction action, it will drive the corresponding connecting plate 54 to move synchronously, so that the vibrating hammer 55 contacts the detection plate 67 on the positioning plate 1 and applies hammering to generate vibration.

[0022] Four slurry detection mechanisms 6 are respectively installed inside four positioning plates 1, with the detection parts on both sides of the slurry detection mechanism 6 extending to the inside and outside of the positioning plate 1, respectively. The four slurry detection mechanisms 6 correspond to the vibration end positions of the vibration mechanism 5. The slurry detection mechanisms 6 are used to detect the overflow height of the slurry and the vibration intensity of the vibration mechanism 5. The slurry detection mechanism 6 includes a first detection groove 61 installed on the side wall of the grouting tank 3. A detection plate 62 is slidably installed at the opening of the first detection groove 61. The detection plate 62 and the first detection groove 61 are connected by a high-precision sealing connection to prevent the slurry from entering the interior of the first detection groove 61 through the gap. Limiting blocks 610 are fixed on both sides of the detection plate 62. Limiting grooves 611 that cooperate with the limiting blocks 610 are provided on both sides of the first detection groove 61. When the limiting blocks 610 move inside the limiting grooves 611, they can limit the movement distance of the detection plate 62 and prevent the detection plate 62 from moving out of the first detection groove 61. The interior of the measuring groove 61 is moved out; a pressure sensor 63 is fixedly installed on the side of the measuring plate 62 facing the interior of the first measuring groove 61. The pressure sensor 63 is a piezoelectric pressure sensor. A first spring 64 is fixedly installed on the side wall of the pressure sensor 63. Telescopic rods 65 are fixedly installed on both sides of the side wall of the measuring plate 62 and on both sides of the pressure sensor 63. The end of the telescopic rod 65 away from the measuring plate 62 is fixedly connected to the side wall of the first measuring groove 61. A second measuring groove 66 is opened on the side of the positioning plate 1 away from the first measuring groove 61. A measuring disk 67 is slidably installed inside the second measuring groove 66. A measuring column 68 extending into the interior of the first measuring groove 61 is fixedly installed on the side wall of the measuring disk 67. One end of the measuring column 68 is fixedly connected to one end of the first spring 64. A second spring 69 is sleeved on the column wall of the measuring column 68. The two ends of the second spring 69 are fixedly connected to the side wall of the measuring disk 67 and the side wall of the second measuring groove 66, respectively.

[0023] The PLC controller 7 is located on one side of the positioning plate 1. The vibration mechanism 5 and the slurry detection mechanism 6 are both electrically connected to the PLC controller 7. The four cylinders 53 in the vibration mechanism 5 are all electrically connected to the PLC controller 7 through actuators (solenoid valves) and feedback elements (magnetic switches, position sensors, etc.), forming an electrical connection link between the cylinders and the PLC controller 7. The feedback element transmits the status signal of the cylinder 53 to the PLC controller 7. The actuator receives the control signal from the PLC controller 7 and drives the cylinder 53 to move. The pressure sensor 63 in the slurry detection mechanism 6 is electrically connected to the PLC controller 7 through wires.

[0024] The operating principle of this invention is described as follows: First, the construction personnel clean the four sides of the precast column foundation to ensure that the installation surface is flat, clean and free of debris. Then, the four positioning plates 1 are spliced ​​one by one to the four sides of the precast column foundation, so that each positioning plate 1 is in a preset position close to the upper end of the foundation. The level of each positioning plate 1 is carefully calibrated to ensure that the bottom of the grouting groove 3 on the positioning plate 1 is flush with the upper end of the precast column foundation, laying the foundation for the smooth flow of material in the subsequent grouting operation. After the positioning plate 1 is initially in place, the first bolt 22 is inserted into the first fixing ring 21 on the side of the two adjacent positioning plates 1 and tightened with the first nut 23. As the first bolt 22 and the first nut 23 are gradually tightened, the four positioning plates 1 gradually form an overall frame and are firmly fixed to the upper end of the precast column foundation. Since the grouting groove 3 on the four positioning plates 1 is spaced at the same distance from the side wall of the precast column foundation, the quality of subsequent grouting can be guaranteed. During this process, the guide seats 42 on the top of two adjacent positioning plates 1 will automatically align and complete the splicing to form an integral structure. The included angle at the splicing point is maintained at 90°, and the included angle position of the guide seat 42 is completely coincident with the included angle position of the frame formed by splicing the four positioning plates 1, providing a unified benchmark for the subsequent hoisting guidance of precast columns. After the installation of positioning plate 1 is completed, the construction personnel will splice the four fixing plates 51 on the four sides of the precast column foundation, so that the fixing plates 51 are directly below the positioning plate 1. During installation, it is necessary to ensure that the vibratory hammer 55 on the side wall of each fixing plate 51 is precisely aligned with the detection disc 67 on the outer side of the corresponding positioning plate 1 in the horizontal direction, so as to ensure that the vibration energy can be effectively transmitted to the detection area. Then, the second bolt 522 is used to pass through the second fixing ring 521 of the adjacent fixing plate 51 and is tightened with the second nut 523, so that the four fixing plates 51 form a stable whole and fit tightly against the side wall of the foundation. After all the components of the positioning device are installed in place and checked to be correct, the power supply of the device is turned on to prepare for the hoisting and docking of the precast column and subsequent grouting operations. Construction workers introduced the grouting pipe of the grouting pump into the grouting tank 3, and started the grouting pump to continuously inject grout into the grouting tank 3. Under the action of its own fluidity and grouting pressure, the grout flowed smoothly along the grouting tank 3 into the connection between the precast column foundation and the precast column. This connection is equipped with a specially designed grouting channel, which can guide the grout to be evenly distributed and completely filled into all areas of the connection interface, ensuring reliable bonding and anchoring after solidification, so that the precast column and the foundation are firmly connected. At the same time, the construction workers issued a command through the PLC controller 7 to synchronously start four cylinders 53. The four cylinders 53 are connected to the same air source through air pipes, and precision gas regulating valves are installed on the air pipes to ensure that the actuation height of each cylinder 53 is consistent. When cylinder 53 retracts, it drives the corresponding connecting plate 54 to move synchronously, causing the vibrating hammer 55 mounted on the connecting plate 54 to contact the detection disc 67 on the positioning plate 1 and apply hammering, causing the detection disc 67 to vibrate. The detection disc 67 efficiently transmits the vibration energy to the positioning plate 1, causing all four positioning plates 1 to vibrate uniformly at the same time. This synchronous vibration can significantly improve the fluidity of the grout, promote the discharge of air bubbles, and reduce dead corners in the filling, thereby greatly improving the grouting quality and the compactness of the connection parts. After the hammering is completed, the PLC controller 7 automatically switches to the cylinder 53 extended state, causing the vibrating hammer 55 to separate from the detection disc 67. Then the above cycle is repeated to achieve continuous and stable vibration of the positioning plate 1. During the hammering process, the detection disc 67 moves inward toward the fixed plate 51 under the action of external force, which compresses the second spring 69 between the detection disc 67 and the second detection groove 66. At the same time, the detection disc 67 drives the detection column 68 to move synchronously, which causes the end of the detection column 68 to squeeze the first spring 64. The change in the elastic force of the first spring 64 directly acts on the pressure sensor 63 (which adopts a piezoelectric pressure sensor, which can accurately capture the effective hammering pressure of the vibrating hammer 55 and minimize the signal interference caused by continuous vibration), which gradually increases the external force between the pressure sensor 63 and the detection plate 62. The pressure sensor 63 converts the pressure signal detected in real time into an electrical signal and transmits it to the PLC controller 7. By analyzing these pressure data, the PLC controller 7 can accurately determine the hammering force applied by each vibrating hammer 55. The intelligent algorithm built into the PLC controller 7 will compare the pressure values ​​at each point and automatically adjust the retraction amount of the corresponding cylinder 53 to ensure that the four positioning plates 1 are always subjected to a uniform hammering force, thereby achieving the best vibration-assisted grouting effect. As the grouting operation continues, the joint between the precast column foundation and the precast column is gradually filled with grout. When the joint reaches fullness, excess grout begins to overflow, gradually accumulating and rising along the bottom of the grouting tank 3. During this process, the grouting tank 3 acts as a buffer container, temporarily accommodating the overflowing grout until its level rises to contact the detection plate 62 on the side wall of the grouting tank 3. At this point, the fluid grout exerts a continuous squeezing force on the detection plate 62, pushing it slowly into the first detection tank 61. This action is directly transmitted to the pressure sensor 63, simultaneously causing the telescopic rods 65 on both sides of the pressure sensor 63 to contract synchronously, forcing the pressure sensor 63 to compress the first spring 64. (It is worth noting that because the elastic force of the second spring 69 is much greater than that of the first spring 64, the compression of the first spring 64 during this process will not push the detection column 68 to move in the opposite direction, ensuring that the detection plate 62 is only driven by the grout pressure, avoiding mutual interference between structural forces.) Force sensor 63 continuously transmits the detected pressure signal to PLC controller 7. By analyzing this stable and continuous pressure change, PLC controller 7 can accurately determine the amount of grout accumulated in grouting tank 3. As a result, the built-in alarm module of PLC controller 7 issues a warning before the grout overflows from grouting tank 3, reminding construction personnel to immediately shut down the grouting pump. This effectively avoids material waste and on-site pollution caused by grout overflow. More importantly, PLC controller 7 has intelligent signal recognition capabilities. The pressure generated by the grout on pressure sensor 63 is continuous, stable, and low in intensity, while the pressure generated by the vibrating hammer 55 is intermittent, pulsed, and high in intensity. PLC controller 7 distinguishes and identifies the waveform characteristics, duration, and intensity threshold of the two signals through built-in algorithms. It can accurately identify the source of pressure and ensure that the judgment of grouting volume and the monitoring of hammering force do not interfere with each other. This enables the reliable application of the same pressure sensor 63 in two scenarios. After the grouting operation is completed, a period of static curing is required to allow the grout to fully solidify and harden, forming a stable structural connection. During this process, the construction workers will conduct a simple cleanup of the site and observe the surface condition of the grout to ensure that there is no abnormal shrinkage or cracks. Once the grout has reached the design strength, the construction workers will begin to remove the positioning device. During the removal process, the construction workers will pay special attention to protecting the completed connection parts to avoid damage caused by tool collisions. After the removal work is completed, a visual inspection will be carried out on the connection area between the precast column and the foundation to confirm that the grouting quality meets the requirements.
