Description

Technical Field

[0001] The present application relates to the technical field of composite floor slabs, and in particular to an adaptive adjustment structure and construction method in the construction of composite floor slabs. Background Art

[0002] With the acceleration of building industrialization, prefabricated buildings are becoming a mainstream trend in the construction industry. Composite floor slabs, a key component of prefabricated concrete structures, are composed of prefabricated thin panels and cast-in-place concrete layers. The prefabricated thin panels are prefabricated in the factory. The installation accuracy of composite floor slabs at the construction site, especially the level control, is directly related to the stability of the entire building structure. Therefore, how to achieve accurate and efficient installation and leveling of composite floor slabs has become a key technical challenge that needs to be overcome in the field of prefabricated buildings.

[0003] Conventional technology typically uses a straightedge and shims to calibrate the levelness of composite floor slabs. After the composite floor slab is hoisted into place, construction workers use a straightedge to check the surface of the slab, ensuring it fits snugly against the slab. A feeler gauge is used to measure the gap between the straightedge and the slab to determine any flatness deviations. For any low spots detected, steel shims of appropriate thickness are inserted between the composite floor slab and the supporting structure, compensating for the height difference. For any raised areas, the support height is adjusted, allowing the downward pressure of the support to level the raised areas.

[0004] Regarding the aforementioned related technologies, the inventors believe that when construction workers use a straightedge and feeler gauge to test the flatness of composite floor slabs, human factors significantly influence the test results. The placement of the straightedge, the amount of force applied, and the angle of insertion of the feeler gauge depend heavily on the operator's experience and feel. Different operators testing the same composite floor slab may obtain slightly different results. This lack of an objective, unified standard results in inaccurate flatness deviation assessments, which in turn affects subsequent corrective measures. Summary of the Invention

[0005] The purpose of this application is to provide an adaptive adjustment structure and construction method in the construction of composite floor slabs, so as to improve the problem that when construction workers use a straightedge and a feeler gauge to detect the flatness of composite floor slabs, human factors have a significant impact on the detection results.

[0006] The first purpose of this application is to provide an adaptive adjustment structure for composite floor construction, which adopts the following technical solutions: An adaptive adjustment structure for composite floor construction includes a base plate, a plurality of support legs being provided on the bottom surface of the base plate, a ball groove being provided at the center of the base plate, and a connecting groove being provided on the top surface of the base plate to connect with the ball groove; a rotating ball being provided to rotate in the ball groove, and support columns being provided along the vertical direction of the rotating ball, and a placement plate for placing the composite floor being provided at one end of the support column away from the base plate; The bottom plate is provided with a plurality of through grooves around the spherical groove as the center circumference, the through grooves being arranged in the up-down direction, and a balancing ball is rotatably mounted in the through grooves; a positioning rod is provided on the top surface of the balancing ball, a positioning plate is provided on the end of the positioning rod away from the balancing ball, a positioning rod is provided on the positioning plate, one end of the positioning rod is abutted against the support column, a hanging rope is connected to the bottom surface of the balancing ball, and a counterweight is provided on the end of the hanging rope away from the balancing ball to maintain the positioning rod upright; Several of the positioning rods are provided with pressure sensors, and a return rod is provided at one end of the positioning rod away from the support column, and the return rod is against the pressure sensor at one end away from the connecting plate; a cover is provided on the top surface of the base plate, and a plurality of hydraulic cylinders corresponding to the positioning rods in the up and down directions are provided on the circumference of the top surface of the cover, and a return plate is provided at the output end of the hydraulic cylinder; the hydraulic cylinder is provided with an oil pipe, and the oil pipe is provided with an electromagnetic valve, and several of the electromagnetic valves and several of the press sensors are provided in a one-to-one correspondence along the up and down directions to control the oil supply to the hydraulic cylinder. When the return rod releases the press sensor, the corresponding hydraulic cylinder pushes the support column through the return plate.

[0007] By adopting the above technical solution, balancing balls and counterweights are set to maintain the positioning rod upright, the positioning rod is used to offset the support column, and the hydraulic cylinder is controlled in conjunction with the pressure sensor and the solenoid valve. When the return rod releases the pressure sensor, the corresponding hydraulic cylinder pushes the support column to achieve adaptive adjustment of the horizontality of the composite floor; it avoids the influence of human factors in traditional straightedge and feeler gauge detection, and can automatically adjust according to the actual state of the composite floor, making the adjustment of the horizontality of the composite floor more accurate and objective.

[0008] Optionally, a plug-in column is provided at the end of the support column away from the rotating ball, and the plug-in column is plugged and fixed to the placement plate. Beams are provided on both sides of the base plate in the up and down directions, and the composite floor is provided with a plurality of screws. After the composite floor is stabilized and leveled, the composite floor is threadedly fixed to the placement plate through the screws. A cross bar is provided at one end of the screw, and the cross bar is abutted against the top surface of the beam to fix the position of the composite floor.

[0009] By adopting the above technical solution, after the composite floor is stabilized and leveled, the placement plate and the composite floor are fixed by screws, and the position of the composite floor is fixed by a number of cross bars and beams on both sides of the bottom plate, ensuring that the position of the floor is stable after leveling and is not prone to displacement or shaking, thereby improving the stability and safety of the composite floor after leveling. It is easy to operate during construction, and the installation and fixation of the composite floor can be completed through simple plug-in and threaded connection, which helps to improve construction efficiency.

[0010] Optionally, a buffer groove is provided at one end of the support column away from the rotating ball, the plug-in column is slidably inserted into the buffer groove, a buffer part is provided on the bottom surface of the buffer groove, and the end of the buffer part away from the bottom surface of the buffer groove is fixed to the bottom surface of the plug-in column.

[0011] By adopting the above technical solution, the buffer groove and buffer member of the support column can play a role in buffering and shock absorption when the support column is impacted by external force, such as the impact force at the moment of floor placement or vibration during subsequent construction; it helps to protect the support column and the composite floor, reduce problems such as component damage and cracks in the composite floor caused by excessive impact force, and help to extend the service life of the structure.

[0012] Optionally, the positioning rod is slidably arranged through the positioning plate, and a connecting plate is provided at one end of the positioning rod away from the support column. The connecting plate and the positioning plate are connected to form an elastic member for resetting the positioning rod.

[0013] By adopting the above technical solution, when the positioning rod is squeezed by the support column and its position changes, the elastic part can keep the positioning rod close to the support column until the support column is vertical, thereby ensuring the continuity and accuracy of the positioning and enabling the entire adaptive adjustment system to work continuously and stably; at the same time, the elastic part helps to buffer the squeezing force of the support column and helps to protect the positioning column.

[0014] Optionally, the positioning rod includes a rod 1 fixed to the connecting plate and a rod 2 with one end abutting against the support column, the rod 1 is provided with a threaded hole, the rod 2 is provided with a threaded rod, and the rod 1 and the rod 2 are threadedly connected.

[0015] By adopting the above technical solution, rod one and rod two of the positioning rod are connected by threads, and the overall length of the positioning rod can be adjusted according to actual conditions so that the positioning rod is close to the support column, which helps to improve the positioning accuracy; at the same time, it is easy to install and debug, and helps to repair and replace rod two.

[0016] Optionally, a ball bearing that abuts against the support column is rotatably provided on one end of the positioning rod close to the support column.

[0017] By adopting the above technical solution, it is helpful to reduce the friction between the positioning rod and the support column, so that the positioning rod can more sensitively sense the position changes of the support column, improve the accuracy and timeliness of detection, and thus enable the hydraulic cylinder to adjust the support column more accurately to ensure the effect of floor level adjustment; reducing friction also reduces the wear on the surface of the positioning rod and the support column, which helps to extend the service life of the components and reduce maintenance costs.

[0018] Optionally, the cover shell is provided with a receiving hole for the support column to pass through, and an elastic pad is provided on the inner side wall of the receiving hole.

[0019] By adopting the above technical solution, the elastic pad on the inner side wall of the cover housing hole can prevent the support column from rigidly colliding with the cover during movement, which helps to protect the support column and extend its service life, while also reducing noise and vibration caused by collision.

[0020] Optionally, a cavity is provided in the elastic pad.

[0021] By adopting the above technical solution, the cavity set in the elastic pad further enhances the buffering performance of the elastic pad, better absorbs and disperses the energy generated when the support column collides with the cover, provides more effective protection, and adapts to greater impact force and displacement changes.

[0022] Optionally, the supporting foot includes a foot tube and a foot rod inserted in the foot tube, the end of the foot rod away from the foot tube is fixed to the base plate, and the outer wall of the foot tube is provided with a plurality of positioning bolts threadedly connected to the foot tube to fix the position of the foot rod.

[0023] By adopting the above technical solution, the foot tube and foot rod of the supporting foot are fixed by positioning bolts, which makes it easy to adjust the height of the supporting foot. In different construction sites, the horizontality and height of the base plate can be flexibly adjusted according to the ground flatness and elevation requirements, providing a stable foundation for the entire adjustment structure. At the same time, it helps the supporting foot adapt to a variety of complex construction environments, thereby improving the versatility and practicality of the equipment.

[0024] The second purpose of this application is to provide a construction method for an adaptive adjustment structure in composite floor construction: S100: Using a lifting device to slowly lift the composite floor slab (71), when the composite floor slab (71) is lifted to above the adaptive adjustment structure, the composite floor slab (71) is initially placed on the placement plate (32); S200: The placement plate (32) and the supporting column (31) are tilted. At this time, the balancing ball (4) maintains the positioning rod (41) vertically under the action of its own gravity and the suspension rope (44) and the counterweight (45). The positioning rod (43) is against the tilted supporting column (31), and the position of the positioning rod (43) changes. The displacement of the positioning rod (43) drives the elastic member (48) on the corresponding positioning plate (42) to deform, and at the same time causes the return rod (471) to release the corresponding pressure sensor (46). The pressure sensor (46) controls the corresponding electromagnetic valve (621) to open, so that the oil pipe (62) supplies oil to the hydraulic cylinder (6), pushing the return plate (61) to act on the supporting column (31), so that the supporting column (31) gradually returns to vertical. The plurality of positioning rods (43) continuously monitor, feedback and adjust in multiple ways until the composite floor (71) reaches the preset horizontal accuracy standard.

[0025] By adopting the above technical solution, by setting a balancing ball and a counterweight to maintain the vertical positioning rod, the positioning rod is counteracted with the support column, the tilt state of the support column is detected, and the hydraulic cylinder is controlled by the pressure sensor and the solenoid valve. When the return rod releases the pressure sensor, the corresponding hydraulic cylinder pushes the support column to achieve adaptive adjustment of the horizontality of the composite floor; it avoids the influence of human factors in traditional straightedge and feeler gauge detection, and can automatically adjust according to the actual state of the composite floor, making the adjustment of the horizontality of the composite floor more accurate and objective.

[0026] In summary, the present application includes at least the following beneficial technical effects of the adaptive adjustment structure and construction method in composite floor construction: 1. By installing a balancing ball and counterweight to maintain the vertical positioning rod, using the positioning rod to counteract the support column, and cooperating with a pressure sensor and solenoid valve to control the hydraulic cylinder, when the return rod releases the pressure sensor, the corresponding hydraulic cylinder pushes the support column to achieve adaptive adjustment of the composite floor level. This avoids the human factor in traditional straightedge and feeler gauge inspection, and can automatically adjust according to the actual state of the composite floor, making the composite floor level adjustment more accurate and objective. 2. After the composite floor is stabilized and leveled, the placement plate and the composite floor are fixed with screws, and the position of the composite floor is fixed by a number of cross bars against the beams on both sides of the bottom plate. This ensures that the position of the floor is stable after leveling and is not prone to displacement or shaking, thereby improving the stability and safety of the composite floor after leveling. The construction process is easy to operate, and the installation and fixation of the composite floor can be completed through simple plug-in and threaded connections, which helps to improve construction efficiency. 3. When the positioning rod is squeezed by the support column and its position changes, the elastic member can keep the positioning rod close to the support column until the support column is vertical, ensuring the continuity and accuracy of positioning and enabling the entire adaptive adjustment system to work continuously and stably; at the same time, the elastic member helps to buffer the squeezing force of the support column and help protect the positioning column.

[0029] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0030] Adaptive adjustment structure and construction method in composite floor slab 71 construction, refer to Figure 1 , comprising a base plate 1, with a plurality of supporting legs 2 provided on the bottom surface of the base plate 1, preferably four in this embodiment, the supporting legs 2 comprising a foot tube 21 and a foot rod 22 inserted into the foot tube 21, the end of the foot rod 22 away from the foot tube 21 being fixed to the base plate 1 by welding. The outer wall of the foot tube 21 is provided with a plurality of positioning bolts 23 threadedly connected to the foot tube 21 to fix the position of the foot rod 22. There is no specific requirement for the number of positioning bolts 23. By tightening the positioning bolts 23, the position of the foot rod 22 in the foot tube 21 can be fixed, thereby adjusting the overall height and levelness of the base plate 1. Construction personnel can adjust the length of the foot rod 22 extending out of the foot tube 21 according to the elevation requirements, so that the base plate 1 reaches an ideal initial installation state.

[0031] Reference Figure 1 、 Figure 2The top surface of the base plate 1 is provided with a cover 5 by means of bolts. The cover 5 has a receiving hole 51 for the support column 31 to pass through. The inner wall of the receiving hole 51 is provided with an elastic pad 511, and the elastic pad 511 has a cavity 5111. The elastic pad 511 is generally made of an elastic material such as rubber and is fixed to the inner wall of the receiving hole 51 by gluing or bolts.

[0032] Reference Figure 1 The top surface of the housing 5 is provided with a plurality of hydraulic cylinders 6 arranged in a circle centered around the receiving space, corresponding one to one with the positioning rods 43 in the vertical direction. In this embodiment, there are four hydraulic cylinders 6. A stop plate 61 is rotatably provided at the output end of the hydraulic cylinder 6. The stop plate 61 is rotatably connected to the output end of the hydraulic cylinder 6 via a pin or hinge. This rotatable arrangement allows the stop plate 61 to better fit the support column 31 when pushing the support column 31.

[0033] Reference Figure 2 A ball groove 11 is defined in the center of the base plate 1, and a connecting groove 111 is defined on the top surface of the base plate 1, connecting to the ball groove 11. A rotating ball 3 is rotatably mounted within the ball groove 11, allowing the rotating ball 3 to flexibly rotate within the groove 11 to adapt to varying forces in different directions. Rotating ball 3 is integrally formed with a support column 31 in the vertical direction. The support column 31 is in the form of a quadrangular prism. A placement plate 32 is provided at the end of the support column 31 away from the base plate 1, for placing the composite floor slab 71.

[0034] Reference Figure 2 The end of the support column 31 away from the rotating ball 3 is provided with a plug-in column 313. The bottom surface of the placement plate 32 is provided with a hole corresponding to the plug-in column 313. The plug-in column 313 and the placement plate 32 are fixed by plugging. The end of the support column 31 away from the rotating ball 3 is provided with a buffer groove 311. The plug-in column 313 is slidably inserted into the buffer groove 311. The bottom surface of the buffer groove 311 is provided with a buffer member 312. In this embodiment, the buffer member 312 is a spring. The end of the buffer member 312 away from the bottom surface of the buffer groove 311 is fixed to the bottom surface of the plug-in column 313 by welding.

[0035] Reference Figure 1 、 Figure 2Beams 7 are provided on both sides of the bottom plate 1 in the vertical direction. The composite floor 71 is provided with a plurality of screws 72. In this embodiment, two rows of screws 72 are provided, totaling six. After the composite floor 71 is stabilized and leveled, the composite floor 71 is screwed to the placement plate 32 via the screws 72. The screws 72 and the threads of the placement plate 32 fit tightly together, effectively fixing the composite floor 71 to the placement plate 32 and preventing it from moving. A crossbar 721 is integrally provided at one end of the screw 72. The crossbar 721 and the screw 72 form an integrally formed structure, which enhances the integrity and strength of the components. The crossbar 721 abuts against the top surface of the beam 7 to fix the position of the composite floor 71. The crossbar 721 acts as a lateral limiter. In conjunction with the vertical fixation of the screws 72, the composite floor 71 is constrained in both the horizontal and vertical directions, ensuring the stability of the position of the composite floor 71 during subsequent construction.

[0036] Reference Figure 2 、 Figure 3 The bottom plate 1 is provided with a plurality of through grooves 12 with the ball groove 11 as the center circumference. In this embodiment, there are four through grooves 12. The through grooves 12 are arranged in the up and down directions. A balancing ball 4 is rotatably fitted in the through groove 12. The fitting of the balancing ball 4 and the through groove 12 is similar to a small spherical bearing structure.

[0037] Reference Figure 3 , a positioning rod 41 is provided on the top surface of the balancing ball 4 by welding, and welding ensures that the positioning rod 41 is firmly connected to the balancing ball 4. A positioning plate 42 is provided on the end of the positioning rod 41 away from the balancing ball 4 by welding, and a positioning rod 43 is provided on the positioning plate 42, and one end of the positioning rod 43 is against the support column 31. The positioning rod 43 includes a rod 1 431 (not shown in the figure) fixed to the connecting plate 47 and a rod 2 432 with one end against the support column 31, the rod 1 431 is provided with a threaded hole 4311, and the rod 2 432 is provided with a threaded rod 4321, and the rod 1 431 and the rod 2 432 are connected by threads. This threaded connection method makes it possible to adjust the overall length of the rod 1 431 and the rod 2 432 according to actual conditions, and the construction personnel can make the positioning rod 43 fit the support column 31 by rotating the rod 2 432.

[0038] Reference Figure 3 The positioning rod 43 slides through the positioning plate 42. The positioning plate 42 has a hole for the positioning rod 43 to pass through, which provides a certain guiding function, ensuring that the positioning rod 43 can only move in the preset direction. A connecting plate 47 is welded to the end of the positioning rod 43 away from the support column 31. The connecting plate 47 is connected to the positioning plate 42 and is provided with an elastic member 48 for resetting the positioning rod 43. In this embodiment, the elastic member 48 is a spring. When the positioning rod 43 is subjected to an external force, such as when the support column 31 is squeezed and displaced, the spring, acting as the elastic member 48, uses its own elastic force to restore the positioning rod 43 to its original position, close to the support column 31, ensuring the continuity and accuracy of positioning.

[0039] Reference Figure 3 The end of the positioning rod 43 near the support column 31 and the end of the second rod 432 near the support column 31 are provided with a ball 433 that rotates and engages with the support column 31. The ball 433 is embedded in a small groove at the end of the positioning rod 43 to achieve rotation, reducing the friction between the positioning rod 43 and the support column 31, making positioning more sensitive.

[0040] Reference Figure 1 、 Figure 2 The bottom surface of the balancing ball 4 is provided with a lifting ring (not shown), which is connected to a lifting rope 44 by a buckle. The buckle connection is simple and reliable. The end of the lifting rope 44 away from the balancing ball 4 is buckled with a counterweight 45, which maintains the vertical position of the positioning rod 41. The gravity of the counterweight 45 keeps the positioning rod 41 in a vertical position, providing a reference for subsequent measurement and adjustment.

[0041] Reference Figure 3 Each of the positioning rods 41 is provided with a pressure sensor 46, which is typically mounted at a predetermined position on the surface of the positioning rod 41 by adhesive bonding or embedding. A return lever 471 is provided at the end of the positioning rod 41 away from the support column 31. In this embodiment, the return lever 471 is U-shaped, and the end away from the connecting plate 47 contacts the pressure sensor 46. When the position of the support column 31 changes, the return lever 471 moves accordingly, changing the pressure on the pressure sensor 46 and triggering a corresponding signal.

[0042] Reference Figure 3 The hydraulic cylinder 6 is provided with an oil pipe 62, which cooperates with external equipment to supply oil to the hydraulic cylinder 6. The oil pipe 62 is equipped with a solenoid valve 621. Several solenoid valves 621 are arranged in a one-to-one correspondence with several pressure sensors 46 along the vertical direction to control the oil supply to the hydraulic cylinder 6. When the return rod 471 releases the pressure sensor 46, the corresponding hydraulic cylinder 6 pushes the support column 31 through the support plate 61. The coordinated cooperation between the several positioning rods 43 and the hydraulic cylinder 6 maintains the support column 31 vertically, thereby leveling the composite floor slab 71 on the placement plate 32. Through this adaptive adjustment method, it can automatically adjust according to the actual state of the composite floor slab 71 to ensure its horizontal state.

[0043] The implementation principle of the embodiment of this application is: Before the construction of the composite floor 71, the adaptive adjustment structure is first installed in the predetermined position. By adjusting the height of the support legs 2, the base plate 1 is brought into a roughly horizontal state by utilizing the cooperation between the leg tubes 21 and the leg rods 22 and the fixation of the positioning bolts 23, laying the foundation for subsequent precise adjustment.

[0044] Begin hoisting the composite floor slab 71, slowly lifting it above the placement plate 32 and initially positioning it. At this point, due to the floor slab's own weight and possible placement deviations, the placement plate 32 and the support column 31 will tilt. The balancing ball 4, within the through-hole 12, will maintain the positioning rod 41 vertically due to its own gravity and the interaction with the suspension rope 44 and counterweight 45. One end of the positioning rod 43 abuts against the tilted support column 31. Because the positioning rod 43 is equipped with a ball bearing 433 near the end of the support column 31, it can sensitively detect subtle displacement changes in the support column 31, allowing the positioning rod 43 to react quickly.

[0045] The positioning rod 43 slides through the positioning plate 42. Its connecting plate 47, located at the end away from the support column 31, is connected to the positioning plate 42 via an elastic member 48. When the positioning rod 43 is displaced due to the tilting of the support column 31, the elastic member 48 corresponding to the positioning rod 43 is compressed, and the corresponding return rod 471 releases the corresponding pressure sensor 46 on the positioning rod 41.

[0046] The pressure sensor 46 transmits a signal to the control system (which can be pre-installed in the device or connected to an external control unit). The control system quickly determines the tilt direction and angle based on a pre-set algorithm and then issues a command to the corresponding solenoid valve 621 to open. Solenoid valve 621 controls the flow of oil into the oil pipe 62 of the hydraulic cylinder 6. The oil pressure pushes the support column 31 against the plate 61 at the output end of the hydraulic cylinder 6. Because the plate 61 is rotatable with the output end of the hydraulic cylinder 6, it can precisely adapt to the tilt angle of the support column 31 and apply a corrective force, restoring the support column 31 to its vertical position.

[0047] Several positioning rods 43 cooperate with each other to continuously maintain the verticality of the support column 31 through continuous sensing, feedback and adjustment, thereby ensuring that the composite floor 71 on the placement plate 32 reaches a horizontal state. The horizontality of the composite floor 71 can be detected by measuring instruments (such as a level, a total station, etc.) to ensure that the flatness error is within the allowable range. After the leveling of the composite floor 71 is completed, the composite floor 71 is threadedly fixed to the placement plate 32 by the screw 72, and the cross bar 721 at one end of the screw 72 is against the top surface of the beam 7, further constraining the composite floor 71 in the horizontal and vertical directions to ensure its stability in subsequent construction; realizing adaptive adjustment of the horizontality of the composite floor 71, avoiding the influence of human factors in traditional straightedge and feeler gauge detection, and automatically adjusting according to the state of the composite floor 71, so that the horizontality adjustment of the composite floor 71 is more accurate and objective.
