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.

[0003] 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.

[0004] To address this, a prefabricated column positioning device for prefabricated frame structures is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a prefabricated column positioning device for assembled frame structures.

[0006] 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:

[0007] 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.

[0009] 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.

[0010] Four slurry detection mechanisms are arranged inside the four positioning plates, and the two side detection parts of the slurry detection mechanisms extend to the inside and outside of the positioning plates respectively, the four slurry detection mechanisms correspond to the vibration end positions of the vibration mechanism respectively, and the slurry detection mechanisms are used for detecting the overflow height of the slurry and the vibration intensity of the vibration mechanism.

[0011] A PLC controller is arranged on one side of the positioning plate, and the vibration mechanism and the slurry detection mechanism are electrically connected with the PLC controller.

[0012] Preferably, the first fixing mechanism comprises first fixing rings fixedly arranged on the side surfaces of adjacent two positioning plates, and first bolts and first nuts matched with each other are arranged between the adjacent two first fixing rings.

[0013] Preferably, the guide mechanism comprises support rods fixedly arranged on the top of adjacent two positioning plates, guide seats are fixedly arranged on the upper ends of the two support rods, the two guide seats are arranged in a 90° joint mode, and inclined guide grooves are arranged on the top of the two guide seats.

[0014] Preferably, the vibration mechanism comprises four fixed plates arranged in a rectangular joint mode, second fixing mechanisms are arranged between the opposite sides of adjacent two fixed plates, air cylinders are fixedly arranged on the outer side surfaces of the four fixed plates, connecting plates extending upwards are fixedly arranged on the moving ends of the four air cylinders, vibration hammers are fixedly arranged on the side of the four connecting plates facing the inside of the four fixed plates, and the four air cylinders are electrically connected with the PLC controller through execution elements and feedback elements.

[0015] Preferably, the second fixing mechanism comprises second fixing rings fixedly arranged on the side surfaces of the fixed plates, and second bolts and second nuts matched with each other are arranged between the adjacent two second fixing rings.

[0016] Preferably, the slurry detection mechanism comprises a first detection groove arranged on the side wall of the grouting groove, a detection plate is slidably arranged at the opening of the first detection groove, a pressure sensor is fixedly arranged on the side of the detection plate facing the inside of the first detection groove, the pressure sensor is electrically connected with the PLC controller through a wire, a first spring is fixedly arranged on the side wall of the pressure sensor, telescopic rods are fixedly arranged on the side wall of the detection plate and located on the two sides of the pressure sensor, and one end of the telescopic rod away from the detection plate is fixedly connected with the side wall of the first detection groove.

[0017] 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.

[0018] 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.

[0019] Compared with existing technologies, the advantages of this invention are as follows:

[0020] 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.

[0021] 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.

[0022] 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.

[0035] The PLC controller 7 is arranged on one side of the positioning plate 1, the vibration mechanism 5 and the slurry detection mechanism 6 are electrically connected with the PLC controller 7, the four cylinders 53 in the vibration mechanism 5 are electrically connected with the PLC controller 7 through execution elements (solenoid valves) and feedback elements (magnetic switches, position sensors, etc.), to form an electrical connection link between the cylinders and the PLC controller 7, the feedback elements transmit the state signals of the cylinders 53 to the PLC controller 7, and the execution elements receive the control signals of the PLC controller 7 and drive the cylinders 53 to act; the pressure sensor 63 in the slurry detection mechanism 6 is electrically connected with the PLC controller 7 through wires.

[0036] The operation principle of the present application is described as follows: the construction personnel first clean the four side walls of the prefabricated column foundation, ensure that the installation surface is flat, clean and free of sundries, then splice the four positioning plates 1 to the four side walls of the prefabricated column foundation one by one, make each positioning plate 1 be at the preset position close to the upper end of the foundation, and carefully calibrate the levelness of each positioning plate 1, ensure that the bottom of the grouting groove 3 on the positioning plate 1 is flush with the upper end surface of the prefabricated column foundation, lay a foundation for the smoothness of subsequent grouting operation, after the positioning plate 1 is initially positioned, the first bolt 22 penetrates the first fixing ring 21 on the side surface of the adjacent two positioning plates 1, and the first nut 23 is fastened and connected, with the gradual tightening of the first bolt 22 and the first nut 23, the four positioning plates 1 gradually form a whole frame and are firmly fixed on the upper end of the prefabricated column foundation, since the grouting grooves 3 on the four positioning plates 1 have consistent distance from the side walls of the prefabricated column foundation, the quality of subsequent grouting can be ensured;

[0037] In this process, the guide seats 42 at the top of the adjacent two positioning plates 1 are automatically aligned and spliced to form a whole structure, the included angle at the splicing place is kept at 90°, and the included angle position of the guide seat 42 is completely coincided with the included angle position of the frame formed by splicing the four positioning plates 1, providing a unified reference for the subsequent hoisting and guiding of the prefabricated column;

[0038] After the installation of the positioning plate 1 is completed, the construction personnel splice the four fixed plates 51 corresponding to the four side walls of the prefabricated column foundation, so that the fixed plate 51 is at the position directly below the positioning plate 1, and during installation, the vibration hammer 55 on the side wall of each fixed plate 51 and the detection disc 67 on the outer side surface of the corresponding positioning plate 1 need to be accurately aligned in the horizontal direction to ensure that the vibration energy can be effectively transmitted to the detection area, then the second bolt 522 penetrates the second fixing ring 521 of the adjacent fixed plate 51, and the second nut 523 is fastened, so that the four fixed plates 51 form a stable whole and tightly fit with 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 connected, and the preparation for the hoisting and docking of the prefabricated column and the subsequent grouting operation is completed;

[0039] The construction personnel introduce the grouting pipe of the grouting pump into the grouting groove 3, start the grouting pump to continuously inject slurry into the grouting groove 3, and the slurry flows stably into the connection between the precast column foundation and the precast column along the grouting groove 3 under the action of its own fluidity and grouting pressure. The connection is provided with a specially designed grouting channel that can guide the slurry to be uniformly distributed and completely filled to each area of the connection interface, so as to ensure reliable bonding and anchoring after solidification, and firmly connect the precast column and the foundation. At the same time, the construction personnel issue an instruction through the PLC controller 7 to synchronously start the four air cylinders 53. The four air cylinders 53 are connected to the same air source through air pipes and are provided with precise gas regulating valves on the air pipes to ensure that the actions of the air cylinders 53 are highly consistent. When the air cylinders 53 perform the retracting action, the corresponding connecting plates 54 are synchronously moved, the vibration hammers 55 mounted on the connecting plates 54 are in contact with the detection disc 67 on the positioning plate 1 and apply hammering, the detection disc 67 is vibrated, the vibration energy is efficiently transmitted to the positioning plate 1 by the detection disc 67, and the four positioning plates 1 are simultaneously vibrated uniformly. The synchronous vibration can significantly improve the fluidity of the slurry, promote the bubble to be discharged, reduce the dead angle of filling, and greatly improve the grouting quality and the compactness of the connection part. After the hammering is completed, the PLC controller 7 is automatically switched to the extended state of the air cylinders 53 to separate the vibration hammers 55 from the detection disc 67, and then the above cycle is repeatedly performed to realize the continuous and stable vibration of the positioning plate 1.

[0040] During the hammering process, the detection disc 67 moves to the inside of the fixed plate 51 under the action of external force, so that the second spring 69 is compressed between the detection disc 67 and the second detection groove 66. At the same time, the detection disc 67 synchronously moves the detection column 68, so that the end of the detection column 68 extrudes the first spring 64. The change of the elastic force of the first spring 64 directly acts on the pressure sensor 63 (a piezoelectric pressure sensor is adopted, which can not only accurately capture the effective hammering pressure of the vibration hammer 55, but also can minimize the signal interference brought by continuous vibration), so that the external force between the pressure sensor 63 and the detection plate 62 gradually increases. The pressure sensor 63 converts the real-time detected pressure signal into an electric signal and transmits it to the PLC controller 7. The PLC controller 7 can accurately judge the hammering force of each vibration hammer 55 by analyzing these pressure data. The intelligent algorithm built in the PLC controller 7 compares the pressure values of each point and automatically adjusts the retraction amount of the corresponding air cylinder 53 to ensure that the four positioning plates 1 are always subjected to uniform and consistent hammering force, so as to realize the best vibration-assisted grouting effect.

[0041] With the continuous progress of the grouting operation, the connection gap between the precast column foundation and the precast column is gradually filled with grout, and when the connection reaches the full state, the excess grout begins to overflow outward and gradually accumulates and rises along the bottom of the grouting groove 3. During this process, the grouting groove 3 acts as a buffer container to temporarily accommodate the overflowing grout until its liquid level rises to contact the detection plate 62 on the side wall of the grouting groove 3. At this time, the grout with fluidity will continuously extrude the detection plate 62, slowly pushing the detection plate 62 to move inside the first detection groove 61. This action directly transmits to the pressure sensor 63, while the extension rods 65 on both sides of the pressure sensor 63 are synchronously retracted, forcing the pressure sensor 63 to form extrusion on the first spring 64 (it is worth noting that due to the greater elastic force of the second spring 69 than the first spring 64, the compression of the first spring 64 will not push the detection column 68 to move in the opposite direction during this process, ensuring that the detection plate 62 is only driven by the pressure of the grout, avoiding force interference between structures). The pressure sensor 63 continuously transmits the real-time detected pressure signal to the PLC controller 7, and the PLC controller 7 can accurately judge the accumulation amount of grout in the grouting groove 3 by analyzing the stable and continuous pressure change, so that the warning module in the PLC controller 7 gives a warning before the grout is about to overflow the grouting groove 3, reminding the construction personnel to immediately close the grouting pump, effectively avoiding the waste of materials and the pollution of the site caused by the overflow of grout. What is particularly key is that the PLC controller 7 has intelligent signal recognition capability. The pressure generated by the grout on the pressure sensor 63 presents the characteristics of continuous, stable and small intensity, while the pressure generated by the hammering of the vibrating hammer 55 presents the characteristics of intermittent, pulse and large intensity. The PLC controller 7 can accurately distinguish the pressure source by distinguishing and recognizing the waveform characteristics, duration and intensity threshold of the two signals, ensuring that the judgment of the grouting amount and the monitoring of the hammering intensity do not interfere with each other, realizing the reliable application of the same pressure sensor 63 in double scenes.

[0042] After the grouting operation is completed, a period of time is needed for curing to allow the grout to fully solidify and harden to form a stable structural connection. During this process, the construction personnel will perform a simple cleaning of the site and observe the surface state of the grout to ensure that there is no abnormal shrinkage or cracks. After the grout reaches the design strength, the construction personnel will begin the removal work of the positioning device. During the removal process, the construction personnel will pay special attention to protecting the completed connection part to avoid damage caused by tool collision. After the removal work is completed, an appearance inspection of the connection area between the precast column and the foundation will be performed to confirm that the grouting quality meets the requirements.

[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
