Description

Technical Field

[0001] The present invention relates to the technical field of composite slab positioning, and in particular to a positioning device and a construction method for prefabricated composite slab construction. Background Art

[0002] Precast composite slabs are composite components composed of a factory-fabricated concrete base plate and a cast-in-place concrete layer. They combine the efficiency of precast components with the integrity of cast-in-place structures. The base plate is typically reinforced with prestressed steel or reinforced trusses and transported to the construction site as formwork. The cast-in-place upper layer ensures coordinated load-bearing through shear-resistant structures in the composite surface (such as roughened surfaces, keyways, or truss reinforcement). This technology reduces on-site formwork, shortens construction time, and improves quality consistency. It is suitable for floor slabs, wall panels, and other applications, aligning with the trend of industrialized construction. Its lightweight, material-efficient, and seismic-resistant properties make it widely used in prefabricated buildings.

[0003] Precast composite slabs are prefabricated building components consisting of a factory-fabricated concrete base and cast-in-place composite layers. Precast bases typically utilize prestressing technology or internal steel trusses to enhance load-bearing capacity and crack resistance. The composite surfaces are roughened, keyed, or welded with truss reinforcement to enhance the bond between new and old concrete. During construction, the precast base serves as formwork to support the cast-in-place upper layers, forming the integral load-bearing structure.

[0004] However, in actual construction, due to the protruding steel bars around the prefabricated composite slab, it is difficult to position it during hoisting. Currently, the position adjustment mainly relies on manual measurement, which is prone to positioning deviation and requires repeated correction, affecting construction efficiency. In addition, adjacent composite slabs form large joints due to inaccurate alignment, which is prone to leakage during pouring, reducing the strength of the node and even causing cracking and water seepage. Therefore, a positioning device and construction method for prefabricated composite slab construction are proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a positioning device and construction method for prefabricated composite slab construction, aiming to improve the problem in the prior art of relying on manual measurement to adjust the position, which is prone to positioning deviation and requires repeated correction.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a positioning device and construction method for prefabricated composite panel construction, comprising a composite panel body, a plurality of mounting mechanisms mounted on the top of the composite panel body, a positioning mechanism mounted on the outside of the composite panel body, and a transmission mechanism disposed on one side of the positioning mechanism; The mounting mechanism includes multiple GPS locators, the tops of the multiple GPS locators are installed in the reserved holes on the top of the composite plate body, grooves are provided on both sides of the interior of the GPS locators, a spring is fixedly connected to the inner wall of one side of the groove, the other end of the spring is fixedly connected to a sliding plate, the other end of the sliding plate is fixedly connected to a ball, and buffer components are provided at the four corners of the bottom of the composite plate body.

[0007] Preferably, the buffer assembly includes a protective block, the top of the protective block is fixedly connected to a limiting ring, the inner wall of the protective block is fixedly connected to a spring 2, the other end of the spring 2 is fixedly connected to the inner wall of the superimposed plate body, and the outer part of the limiting ring is slidably connected to the inner wall of the superimposed plate body.

[0008] Preferably, the positioning mechanism includes a mounting box, the top inner wall of the mounting box is fixedly connected to a motor, the driving end of the motor is fixedly connected to a rotating plate, both sides of the rotating plate are rotatably connected to connecting rods, the other end of the connecting rod is rotatably connected to a support platform, the top of the support platform is fixedly connected to a telescopic rod, the other end of the telescopic rod is fixedly connected to a sliding block, one side of the sliding block is fixedly connected to a control panel, and the other end of the control panel is fixedly connected to a positioning plate.

[0009] Preferably, the transmission mechanism includes two sliding frames, one side of the sliding frame is fixedly connected to an extension block, the top of the extension block is installed with a slide rail, the bottom of the sliding block is slidably connected to the top of the slide rail, one side of the sliding frame is fixedly connected to a plurality of teeth, the inner wall of the installation box is rotatably connected to a gear, and the teeth are meshed with the gear.

[0010] Preferably, the outer portion of the sliding frame is slidably connected to the inner wall of the installation box, and the outer portion of the rotating plate is rotatably connected to the inner wall of the installation box.

[0011] Preferably, slide grooves are provided on both sides of the installation box, and the outer portion of the control panel is slidably connected to the inner wall of the slide groove.

[0012] Preferably, a hook is installed on the top of the installation box, and the inner side wall of the positioning plate is in contact with the outside of the composite plate body.

[0013] Preferably, the outside of the sphere is slidably connected to one side of the GPS locator, and the outside of the sphere is engaged with the reserved hole of the composite plate body.

[0014] Preferably, the plurality of GPS locators are evenly distributed on the top four corners and side walls of the composite plate body, and the outer portion of the sliding plate is slidably connected to the inner wall of the GPS locator.

[0015] A prefabricated composite slab construction method is used as follows: S1. Insert the GPS tracker into the reserved hole at the top of the laminated plate. When the ball contacts the inner wall of the hole, the sliding plate compresses spring 1, causing the ball to retract. After the tracker is fully inserted, spring 1 releases its elastic force, pushing the ball into the spherical groove of the reserved hole, achieving self-locking fixation. S2. Start the motor to drive the rotating plate to rotate, and push the support platform to move through the connecting rod, so that the telescopic rod drives the sliding block and the control plate, driving the positioning plate to clamp the laminated plate body. The telescopic rod adjusts the clamping force, and the sliding block drives the teeth to move through the extension block and the sliding frame, and the meshing gears realize synchronous movement on both sides; S3. The GPS locator sends position data to the data processing unit in real time, automatically calculates the deviation between the actual position and the designed coordinates, and displays it through the GPS base station. Construction personnel can quickly adjust the position of the composite slab based on the feedback; S4. During construction, the protective block contacts the working surface, pushing the limiting ring to compress the spring 2 to form a buffer force. After installation is completed, the protective block is completely retracted into the composite plate body, hiding the buffer component.

[0016] In summary, the present invention includes at least one of the following beneficial technical effects: 1. In the present invention, when the GPS locator is inserted into the reserved hole, the ball at its bottom is compressed and pushes the sliding plate to compress the spring, causing the ball to temporarily retract. After the locator is fully inserted, the spring releases its elastic force, pushing the sliding plate to make the ball fit into the spherical groove on the inner wall of the reserved hole, achieving self-locking fixation. This mechanical matching structure ensures that the GPS locator is installed firmly and avoids deviation caused by construction vibration. At the same time, the GPS locator transmits position data to the data processing unit in real time, automatically calculates deviations and guides adjustments by comparing with the design coordinates, completely replacing the traditional manual measurement method, controlling the installation accuracy of the composite plate to the millimeter level, and significantly reducing the time for repeated adjustments.

[0017] 2. In the present invention, the motor drives the rotating plate to drive the connecting rod to move, so that the support platform pushes the telescopic rod and the sliding block to move the linkage control plate, so as to realize the precise clamping of the positioning plate to the composite plate. The telescopic rod can adjust the clamping force, and the gear tooth synchronization mechanism ensures that the positioning plates on both sides move synchronously to avoid deflection. The mechanical linkage system realizes the automatic positioning and fixation of the composite plate, replacing the traditional manual adjustment method, and improving the installation efficiency.

[0018] 3. In the present invention, the protective block pushes the limiting ring to slide when it contacts the construction surface, and compresses the spring 2 to generate a buffering force, which effectively absorbs the construction impact and protects the composite plate body from damage. When the composite plate is installed in place, the protective block is completely retracted into the plate body, which not only realizes the buffering protection function, but also avoids the interference of exposed components on the construction. The buffer structure is cleverly designed, which maintains the flatness of the appearance of the composite plate while ensuring the protective effect, making the construction process safer and more efficient, reducing the risk of component damage, and improving the overall construction quality.

[0021] The following is combined with Figure 1 -Attached Figure 7 , the present invention is described in further detail.

[0022] Reference Figure 1 , Figure 2 and Figure 4The present invention provides a positioning device and construction method for prefabricated composite slab construction, comprising a composite slab body 1, a plurality of mounting mechanisms 2 mounted on the top of the composite slab body 1, a positioning mechanism 4 mounted on the outside of the composite slab body 1, a transmission mechanism 5 disposed on one side of the positioning mechanism 4, the composite slab body 1 is positionally monitored by the mounting mechanisms 2, and the positioning mechanism 4 and the transmission mechanism 5 are linked to form a mechanically fixed closed loop for the composite slab body 1; Specifically, the installation mechanism 2 monitors the spatial coordinates of the composite plate body 1 in real time and transmits the data to the control system. When a position deviation is detected, the control system independently starts the transmission mechanism 5 and drives the positioning mechanism 4 to mechanically adjust the composite plate. The installation mechanism 2 is only responsible for monitoring the positioning and does not participate in the mechanical adjustment process. The positioning mechanism 4 and the transmission mechanism 5 form an independent execution closed-loop system to achieve accurate and efficient automated positioning construction.

[0023] The mounting mechanism 2 includes multiple GPS locators 21. The tops of the multiple GPS locators 21 are installed in the reserved holes on the top of the composite board body 1. The installation positions of the GPS locators 21 are distributed at the four corners and side walls of the composite board body 1 after mechanical calculation to ensure that the positioning signal covers the entire board surface. Grooves 22 are provided on both sides of the interior of the GPS locator 21. A spring 23 is fixedly connected to the inner wall of one side of the groove 22. The depth of the groove 22 matches the natural length of the spring 23, so that the spring 23 is always in linear deformation when compressed. In the interval, the other end of the spring 1 23 is fixedly connected to the sliding plate 24, and the other end of the sliding plate 24 is fixedly connected to the ball 25. The sliding path of the sliding plate 24 is parallel to the groove 22, ensuring that the movement direction of the ball 25 is perpendicular to the axis of the GPS locator 21. The outer part of the ball 25 is slidably connected to one side of the GPS locator 21, and the outer part of the ball 25 is engaged with the reserved hole of the composite plate body 1. The diameter of the ball 25 is slightly larger than the opening of the reserved hole. The elastic force of the spring 1 23 forms an interference fit to prevent the GPS locator 21 from falling off; Specifically, the installation mechanism 2 monitors the spatial position of the composite plate body 1 in real time through the GPS locator 21. After the GPS locator 21 is embedded in the reserved hole, the ball 25 inside it is pushed outward under the elastic force of the spring 23, forming an interference fit with the inner wall of the reserved hole to ensure a stable installation. When the composite plate is slightly displaced, the GPS locator 21 will feedback the coordinate deviation in real time, triggering the subsequent positioning mechanism 4 to make corrections. The linear deformation characteristics of the spring 23 ensure that the ball 25 always fits tightly in the reserved hole to avoid loosening due to vibration or impact, ensuring that the positioning signal is continuously accurate. The reasonable layout of the four corners and side walls makes the monitoring data more comprehensive and improves the construction positioning accuracy.

[0024] refer to Figure 3, buffer components 3 are provided at the four corners of the bottom of the composite plate body 1. The buffer components 3 and the mounting mechanism 2 on the top form a spatially symmetrical layout to jointly resist multi-dimensional impacts during construction. The buffer component 3 includes a protective block 31. The top of the protective block 31 is fixedly connected to a limiting ring 32. The inner diameter of the limiting ring 32 is matched with the gap between the hole wall of the composite plate body 1, limiting the protective block 31 to move only in the vertical direction. The inner wall of the protective block 31 is fixedly connected to a spring 23. The other end of the spring 23 is fixedly connected to the inner wall of the composite plate body 1. The stiffness coefficient of the spring 23 is higher than that of the spring 1 23, and it preferentially absorbs the impact energy when the composite plate body 1 falls; Specifically, the movement trajectory of the protective block 31 is constrained by the vertically guided limiting ring 32 to ensure that the impact force is transmitted axially. When the composite plate body 1 is impacted, the high-rigidity spring 2 33 is compressed first to absorb kinetic energy, and the protective block 31 moves downward synchronously for buffering. After the impact is eliminated, it is reset under the action of elastic force. This mechanism works in conjunction with the top mounting mechanism 2 to form a two-way buffer system, which effectively protects the composite plate and the internal GPS locator 21 from damage caused by dynamic construction loads.

[0025] refer to Figures 5 to 7 The positioning mechanism 4 includes a mounting box 41. The top inner wall of the mounting box 41 is fixedly connected to a motor 42. The mounting box 41 provides sealing protection for the motor 42 to prevent dust from affecting its operation at the construction site. The driving end of the motor 42 is fixedly connected to a rotating plate 43. Both sides of the rotating plate 43 are rotatably connected to connecting rods 44. The starting of the motor 42 will drive the rotating plate 43 to rotate, so that the connecting rod 44 rotates. The other end of the connecting rod 44 is rotatably connected to a support platform 45. The top of the support platform 45 is fixedly connected to an extension rod 44. The retracting rod 46 and the support platform 45 convert the swing of the connecting rod 44 into the linear motion of the telescopic rod 46. The other end of the telescopic rod 46 is fixedly connected to a sliding block 47. One side of the sliding block 47 is fixedly connected to a control plate 48. The contact surface between the sliding block 47 and the slide rail 53 is provided with a lubricating coating to reduce the friction resistance when the control plate 48 moves. The other end of the control plate 48 is fixedly connected to a positioning plate 49. The inner side wall of the positioning plate 49 contacts the outside of the composite plate body 1, and the composite plate body 1 is fixed by the positioning plate 49. Specifically, after the motor 42 is started, it drives the rotating plate 43 to rotate, driving the connecting rods 44 on both sides to swing synchronously. The connecting rods 44 push the support platform 45 to perform reciprocating motion, thereby driving the telescopic rod 46 to perform linear telescopic movement. The sliding block 47 at the end of the telescopic rod 46 moves smoothly along the slide rail 53, driving the control plate 48 and the positioning plate 49 to move laterally. When the positioning plate 49 contacts the side of the composite plate body 1, mechanical locking is achieved by continuous pressure, and the lubricating coating ensures low-friction operation of the sliding block 47. The forward and reverse control of the motor 42 can realize the clamping and release of the positioning plate 49, forming an adjustable rigid fixing system.

[0026] The transmission mechanism 5 includes two sliding frames 51, one side of the sliding frame 51 is fixedly connected to an extension block 52, the length of the extension block 52 matches the stroke of the sliding frame 51, ensuring that the rotation angle of the gear 55 accurately corresponds to the displacement of the positioning plate 49, one side of the sliding frame 51 is fixedly connected to a plurality of teeth 54, the inner wall of the mounting box 41 is rotatably connected to a gear 55, the pitch of the teeth 54 is an integer multiple of the pitch circle diameter of the gear 55, to avoid cumulative errors during the transmission process, the teeth 54 and the gear 55 are meshingly connected, and the meshing of the teeth 54 and the gear 55 enables the gear 55 to rotate, the outer portion of the sliding frame 51 is slidably connected to the inner wall of the mounting box 41, so that the sliding frame 51 can slide stably, and the outer portion of the rotating plate 43 is rotatably connected to the inner wall of the mounting box 41; refer to Figure 2 , both sides of the mounting box 41 are provided with a slide groove 6, and the outer portion of the control panel 48 is slidably connected to the inner wall of the slide groove 6, so that the sliding of the control panel 48 will be restricted; Specifically, when the motor 42 drives the rotating plate 43 to rotate, the connecting rod 44 pushes the support platform 45 to move, driving the telescopic rod 46 and the sliding block 47 to move horizontally. The sliding block 47 is linked to the sliding frame 51 through the control panel 48, so that it can slide stably in the installation box 41. The teeth 54 of the sliding frame 51 are precisely engaged with the gear 55, converting the linear motion into the rotational motion of the gear 55. The rotation angle of the gear 55 strictly corresponds to the displacement of the teeth 54, ensuring that the moving stroke of the positioning plate 49 is accurately controllable. The extension block 52 limits the maximum stroke of the sliding frame 51 to avoid overload. The entire transmission system realizes efficient power transmission and precise displacement control through the engagement of the gear 55 rack.

[0027] A prefabricated composite slab construction method is used as follows: S1. Insert the GPS tracker 21 into the reserved hole at the top of the composite plate body 1. When the ball 25 contacts the inner wall of the hole, the sliding plate 24 is pushed to compress the spring 1 23, causing the ball 25 to retract. After the tracker is fully inserted, the spring 1 23 releases its elastic force, pushing the ball 25 into the spherical groove of the reserved hole to achieve self-locking fixation. S2. Start the motor 42 to rotate the rotating plate 43, which pushes the support platform 45 to move through the connecting rod 44. The telescopic rod 46 drives the sliding block 47 and the control plate 48, which drives the positioning plate 49 to clamp the laminated plate body 1. The telescopic rod 46 adjusts the clamping force. The sliding block 47 drives the teeth 54 to move through the extension block 52 and the sliding frame 51, and the meshing gear 55 realizes synchronous movement on both sides. S3, GPS locator 21 sends position data to the data processing unit in real time, automatically calculates the deviation between the actual position and the designed coordinates, and displays it through the GPS base station. Construction personnel can quickly adjust the position of the composite board according to the feedback; S4. During construction, the protective block 31 contacts the working surface, pushing the limiting ring 32 to compress the second spring 33 to form a buffer force. After the installation is completed, the protective block 31 is completely retracted into the composite plate body 1, hiding the buffer assembly 3.

[0028] Working principle: When the device needs to be used, the GPS locator 21 is inserted into the reserved hole at the top of the laminate body 1. When the ball 25 contacts the inner wall of the hole of the laminate body 1, the ball 25 pushes the sliding plate 24 to squeeze the spring 1 23. At this time, the ball 25 will retract into the inner wall of the GPS locator 21 until the bottom of the GPS locator 21 contacts the inner wall of the reserved hole of the laminate body 1, so that the spring 1 23 releases its elastic potential energy to push the sliding plate 24 to drive the ball 25, so that the ball 25 engages with the spherical groove of the reserved hole inside the laminate body 1, thereby realizing the installation of the GPS locator 21. After the GPS locator 21 is installed, the motor 42 is started, and the rotation plate 43 is driven to rotate by the start of the motor 42, and the rotation of the rotation plate 43 drives the connecting rod 44 to rotate. At this time, the connecting rod 44 drives the support platform 45 to move, and the movement of the support platform 45 can make the telescopic rod 46 move. Under the movement of the telescopic rod 46, the sliding block 47 is driven to make the control plate 48 drive the positioning plate 49 to move. The movement of the positioning plate 49 can contact the outside of the laminated plate body 1, so that the laminated plate body 1 can be clamped. The sliding block 47 is held fixed, and before being clamped and fixed, the sliding block 47 can be driven to move by starting the telescopic rod 46, so that the sliding block 47 drives the control plate 48 to control the positioning plate 49 to move. When the sliding block 47 moves, it drives the extension block 52, so that the extension block 52 drives the sliding frame 51 to move. The movement of the sliding frame 51 drives the teeth 54 to move, and the teeth 54 mesh with the gear 55, so that the gear 55 rotates. The rotation of the gear 55 can make the sliding frames 51 on both sides keep moving synchronously, and finally the position of the positioning plate 49 is adjusted. Finally, during construction, the GPS locator 21 receives and sends the location information to the data processing unit in real time. The data processing unit automatically calculates the actual position of the composite plate based on the received location information, and displays the position of the composite plate through the GPS base station and compares it with the designed position. The commander guides the construction personnel to quickly adjust the positioning of the composite plate based on the location information displayed by the GPS base station to improve construction efficiency. During construction, the protective block 31 will first contact the construction surface, so that the protective block 31 pushes the limiting ring 32 to slide on the inner wall of the composite plate body 1. At this time, the spring 2 33 will be squeezed by the protective block 31, causing the spring 2 33 to deform and generate elastic potential energy, which can provide buffering force and protect the composite plate body 1 during construction. When the composite plate body 1 is installed, the protective block 31 will be completely retracted into the inner wall of the composite plate body 1, thereby hiding the buffer component 3 to avoid affecting the construction.
