Abstract
Description
Technical Field
[0001] This invention relates to the field of floor construction technology, and in particular to a flatness control device for large-area concrete floor construction. Background Technology
[0002] The ground floor is the part of the ground floor room that comes into contact with the soil layer. It bears the load of the ground floor room and is required to have certain strength and rigidity, as well as moisture-proof, waterproof, heat-insulating, and wear-resistant properties. The ground floor and the building's outdoor site are closely related. It is important to properly handle the relationship between the ground floor and platforms, steps, and the edges of the building to ensure a clear connection between the building and the site and overall harmony.
[0003] During large-area concrete construction, uneven mixing and spreading of concrete, uneven concrete gradation, and inadequate control of the water-cement ratio can lead to inconsistencies in the density, wetness, and shrinkage of the concrete mixture, resulting in localized unevenness. Uneven concrete spreading thickness and uneven vibration compaction will also cause inconsistent concrete shrinkage, affecting the smoothness. Insufficient or excessive vibration, and poor slurry leveling, will all make manual surface finishing difficult, resulting in unsatisfactory smoothness.
[0004] To reduce surface cracks and improve surface smoothness, a segmented pouring method is used for large-area concrete construction. Workers use guide rails and wire mesh to divide the extra-long concrete block into several smaller blocks with a calculated length to prevent cracking. After a short period of stress release, these smaller blocks are then connected together, relying on the concrete's tensile strength to resist the subsequent temperature shrinkage stress. When pouring concrete into each smaller block, the guide rails and wire mesh act as formwork to prevent concrete leakage. When workers use a concrete vibrator to compact the concrete near the guide rails and wire mesh, the vibrator causes them to shake continuously, potentially leading to misalignment and concrete leakage at the connection point. Furthermore, the misalignment of the guide rails can result in unevenness on the concrete surface.
[0005] Therefore, it is necessary to provide a new flatness control device for large-area concrete floor construction to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with related technologies, the flatness control equipment for large-area concrete floor construction provided by this invention has the following beneficial effects:
[0017] This invention provides a flatness control device for large-area concrete floor construction. After the reinforcing cage is tied, multiple concrete blocks are placed at designed positions on the surface of the reinforcing cage. A wire mesh is then installed between two concrete blocks and fixed to the wire mesh and reinforcing cage by welding with reinforcing bars. A pressure plate is placed at the top of the wire mesh, and a guide rail is placed inside the groove. The guide rail moves downward inside the concrete block, pressing the pressure plate so that the triangular-sectioned pressure plate enters the interior of the wire mesh. The sidewall of the wire mesh has a "Y"-shaped structure. When the pressure plate enters the concrete block... Inside the wire mesh, the pressure plate continuously presses the wire mesh towards the reinforcing steel bar, while the wire mesh tightly presses against the pressure plate, fixing the pressure plate to the top of the wire mesh. When installing the guide rail, the surface of the guide rail is leveled, and the top surface of the guide rail serves as the reference surface for the floor. After the guide rail is installed, the spliced steel bars are tied to the reinforcing cage with steel wire, fixing the concrete block to the surface of the reinforcing cage. After the guide rail and wire mesh are installed, the concrete pouring area is divided into multiple sections. When pouring concrete into the sections, the leveling mechanism is located on the surface of the guide rail. When a concrete vibrator is used to vibrate the concrete, this... When the third hydraulic rod operates, it drives the fixed rod to rotate. The fixed rod drives the fixed plate and the roller to rotate, causing the roller to press tightly against the side wall of the guide rail. Simultaneously, the vibration leveling mechanism moves, causing the fixed block to operate. The fixed block causes the rubber pad to contact the guide rail. The side wall of the rubber pad has an arc-shaped structure. The guide rail squeezes the rubber pad, pushing the rubber pad and the protrusion to move and squeeze the spring and the elastic rod. The spring and the elastic rod are squeezed in the opposite direction, pushing the rubber pad to press tightly against the side wall of the guide rail. When vibrating concrete, the roller and the rubber pad tightly squeeze the guide rail, reducing the sway of the guide rail and facilitating the use of the guide rail as a reference. Concrete is poured onto the surface; and a pressure plate is installed at the connection between the guide rail and the wire mesh. One end of the pressure plate, which has a triangular cross-section, is inserted into the interior of the wire mesh. At the same time, the wire mesh, which has a "Y" shaped cross-section and is being squeezed, moves towards the center to press the pressure plate, so that the top surface of the pressure plate is in close contact with the bottom surface of the guide rail, preventing serious leakage of grout at the connection between the wire mesh and the guide rail. After a section of concrete is vibrated, the vibrating and leveling mechanism operates, driving the squeezing mechanism to move upward and separate from the guide rail. The leveling mechanism operates and moves along the guide rail, using the guide rail as a reference surface to initially smooth the surface of the concrete. At the same time, the vibrating and leveling mechanism moves to lift, level, and scrape the surface of the concrete. Attached Figure Description

Figure 10 This is a schematic diagram of the circuit structure provided by the present invention. The flatness control equipment for large-area concrete floor construction includes: a floor 1; a leveling mechanism 3; and a separating mechanism 2. The separating mechanism 2 includes a guide rail 21, a concrete block 22, splicing steel bars 23, reinforcing steel bars 24, a wire mesh 25, a pressure plate 26, and a groove 27. The surface of the guide rail 21 is slidably connected to the leveling mechanism 3, and the guide rail 21 engages with the groove 27. The two ends of the concrete block 22, whose sidewall is trapezoidal, are respectively provided with the groove 27 and the splicing steel bars 23. The wire mesh 25 is laid inside the floor 1. 5.

The fixing blocks 95 are symmetrically installed on both sides of the leveling mechanism 4, and the protrusion 92 is slidably connected inside the fixing block 95; the protrusion 92... The spring 94 and the rubber pad 91 are respectively installed at both ends of the guide rail 21, and the rubber pad 91 with an arc-shaped sidewall abuts against the sidewall of the guide rail 21; the spring 94 and the elastic rod 93 are installed inside the fixing block 95, and one end of the elastic rod 93 abuts against the protrusion 92; the reinforcing mechanism 5 includes a fixing rod 51, a third hydraulic rod 52, a fixing plate 53 and a roller 54, and the two sides of the flattening mechanism 3 are symmetrically rotatably connected to the fixing rod 51, and the two ends of the third hydraulic rod 52 are respectively rotatably connected to the fixing rod 94 and the third hydraulic rod 92. The fixed rod 51 and the leveling mechanism 3 are included; one end of the fixed rod 51 is equipped with the fixed plate 53, the roller 54 is rotatably connected inside the fixed plate 53, and the roller 54 is slidably connected to the guide rail 21; the drive mechanism 6 is connected to the vibrating leveling mechanism 4 and the third hydraulic rod 52; the filter mechanism 8 is installed on the side wall of the drive mechanism 6; the compression mechanism 7 is installed inside the leveling mechanism 3 and is connected to the drive mechanism 6.
[0031] The leveling mechanism 3 includes a frame 31, a roller 32, a motor 33, a rubber ring 34, and a sleeve 35. The roller 32 is slidably connected to the guide rail 21, and the roller 32 is symmetrically rotatably connected to the side wall of the frame 31. The sleeve 35 is respectively installed on the side wall of the frame 31 and the roller 32, and adjacent sleeves 35 are connected by the rubber ring 34. The motor 33 is installed on the side wall of the frame 31, and one of the motors 33 intercepts the sleeve 35. In order to facilitate the operation of the motor 33 to drive the sleeve 35, the rubber ring 34, and the roller 32 to rotate, the roller 32 rolls along the surface of the guide rail 21, thereby initially leveling the surface of the concrete with the top surface of the guide rail 21 as the reference surface.
[0032] The leveling mechanism 4 includes a mounting plate 41, a first hydraulic rod 42, a connecting plate 43, an inclination sensor 44, a vibration motor 45, a leveling ruler 46, and a second hydraulic rod 47. The first hydraulic rod 42 is symmetrically mounted on the sidewall of the frame 31. One end of the first hydraulic rod 42 is mounted on the mounting plate 41, and the fixing block 95 is symmetrically mounted on the bottom end of the mounting plate 41. The second hydraulic rod 47 is symmetrically mounted on the sidewall of the mounting plate 41. The top end of the second hydraulic rod 47 is connected to the connecting plate 43, and the leveling ruler 46 is mounted on the bottom end of the connecting plate 43. The inclination sensor 44 and the vibration motor 45 are mounted on the sidewall of the leveling ruler 46. To allow the first hydraulic rod 47 to be used when the leveling ruler 46 is needed, the first hydraulic rod 47... The operation of the 42 mechanism drives the mounting plate 41, the connecting plate 43, and the vibrating ruler 46 downwards, bringing the vibrating ruler 46 into contact with the concrete surface. The vibration motor 45 is then activated, causing the vibrating ruler 46 to vibrate on the concrete surface. As the vibrating ruler 46 moves across the concrete surface, it lifts, levels, and smooths the concrete surface. During the operation of the vibrating ruler 46, the tilt sensor 44 detects whether the vibrating ruler 46 is horizontal. When the surface of the vibrating ruler 46 tilts, the second hydraulic rod 47 moves, causing the mounting plate 41 and the vibrating ruler 46 to move up and down, thus bringing the vibrating ruler 46 to a horizontal position and increasing the flatness of the concrete surface.
[0033] The first hydraulic rod 42, the second hydraulic rod 47, and the third hydraulic rod 52 each include a slide rod 421, a cylinder 422, and a compression plug 423. The compression plug 423 is slidably connected inside the cylinder 422, and one end of the compression plug 423 is fixedly connected to the slide rod 421. The drive mechanism 6 includes an oil pump 61, an oil tank 62, a return oil pipe 63, an inlet oil pipe 64, a feed pipe 65, a discharge pipe 66, and a solenoid valve 67. The feed pipe 65 and the discharge pipe 66 are installed at both ends of the cylinder 422, and the solenoid valve 67 is installed on the side walls of the feed pipe 65 and the discharge pipe 66, respectively. The oil tank 62 is installed inside the frame 31, and the oil pump 61 is installed inside the oil tank 62. The oil return pipe 63 is installed on the side wall of the filter tank 62, and the oil return pipe 63 is connected to the discharge pipe 66. The feed pipe 65 is connected to the oil inlet pipe 64. The filter mechanism 8 includes a screw plug 81, an installation pipe 82, a filter element 83, a fixing cover 84, a sealing sleeve 85, a suction pipe 86, a collection pipe 87, and a connecting rod 88. The oil pump 61 is connected to the suction pipe 86, and the fixing cover 84 is installed at the top of the suction pipe 86. The installation pipe 82 is installed at the top of the oil tank 62, and the installation pipe 82 is threadedly connected to the screw plug 81. The connecting rod 88 and the two ends of the filter element 83 are respectively fixedly connected to the screw plug 81 and the collection pipe 87. The sealing sleeve 85 is installed inside the collection pipe 87, and the sealing sleeve 85 is connected to the suction pipe 86. The slide rod 421 needs to extend from the inside of the cylinder 422. When this is done, the solenoid valve 67 on the side wall of the feed pipe 65 at the top of the cylinder 422 opens, and the solenoid valve 67 on the side wall of the discharge pipe 66 at the bottom of the cylinder 422 opens. The oil pump 61 operates to bring the hydraulic oil inside the oil tank 62 into the filter element 83 through the suction pipe 86. A sealing sleeve 85 is installed between the suction pipe 86 and the collection pipe 87 to prevent the hydraulic oil inside the filter element 83 from leaking out. This allows the hydraulic oil inside the filter element 83 to pass through the filter element 83 and enter the inside of the oil inlet pipe 64. The filter element 83 filters the hydraulic oil, leaving impurities inside the filter element 83. To prevent impurities from affecting the operation of the hydraulic rod, the hydraulic oil inside the inlet pipe 64 enters the top of the cylinder 422 through the inlet pipe 64, pushing the compression plug 423 and the slide rod 421 downward inside the cylinder 422. At the same time, the compression plug 423 pushes the hydraulic oil at the bottom of the cylinder 422 back into the oil tank 62 through the outlet pipe 66 and the return pipe 63. When the hydraulic oil inside the filter element 83 is not moving, the impurities inside the hydraulic oil settle downward and enter between the sealing sleeve 85 and the collection pipe 87 to collect the impurities, reducing the impurities inside the filter element 83. The fixing cover 84 reduces the probability of impurities entering the suction pipe 86 and prevents the suction pipe 86 from becoming blocked.
[0034] The compression mechanism 7 includes a connecting pipe 71, a compression cylinder 72, a piston 73, a pull rod 74, a turntable 75, and a slide groove 76. The connecting pipe 71 is symmetrically installed on the side wall of the oil tank 62. The two ends of the compression cylinder 72 are respectively fixedly connected to the connecting pipe 71. The piston 73 and the pull rod 74 are slidably connected inside the compression cylinder 72. The top end of the pull rod 74 is fixedly connected to the piston 73. The turntable 75 is fixedly connected to the side wall of one of the sleeve shafts 35. The side wall of the turntable 75 is provided with an elliptical slide groove 76. The pull rod 74 is slidably connected inside the slide groove 76. (Winter construction) At this time, due to the decrease in temperature, the fluidity of the hydraulic oil decreases, which is not conducive to the circulation of the hydraulic oil in the cylinder and the oil tank. When the sleeve shaft 35 rotates, it drives the turntable 75 to rotate. The turntable 75 drives the elliptical slide groove 76 to rotate. One end of the pull rod 74 is stuck inside the slide groove 76. When the slide groove 76 rotates, it drives the pull rod 74 and the piston 73 to move up and down continuously inside the compression cylinder 72, thereby driving the lubricating oil to move back and forth continuously inside the oil tank 62 and the compression cylinder 72, thereby increasing the fluidity of the lubricating oil and making it easier for the oil pump 61 to draw hydraulic oil.
[0035] The floor 1 is provided with a steel cage 11 and a subfloor 12. The steel cage 11 is placed on the surface of the subfloor 12. Multiple concrete blocks 22 are placed on the surface of the steel cage 11, and the splicing steel bars 23 are welded to the side walls of the steel cage 11 to facilitate fixing the concrete blocks 22 and the wire mesh 25 to the surface of the steel cage 11.
[0036] The side wall cross-section of the wire mesh 25 is Y-shaped, and the internal sliding connection cross-section of the wire mesh 25 is a triangular pressure plate 26. In order to facilitate the insertion of the pressure plate 26 into the interior of the wire mesh 25, the pressure plate 26 is fixed between the wire mesh 25 and the guide rail 21.
[0037] The working principle of the flatness control device for large-area concrete floor construction provided by this invention is as follows: After the concrete subbase 12 solidifies, the reinforcing cage 11 is installed on the surface of the subbase 12; after the reinforcing cage 11 is tied, multiple concrete blocks 22 are placed at the designed positions on the surface of the reinforcing cage 11, and then the wire mesh 25 is installed between two concrete blocks 22, and the reinforcing steel bars 24 are welded to the wire mesh 25 and the reinforcing cage 11 to fix them; the pressure plate 26 is placed at the top of the wire mesh 25, and then the guide rail 21 is placed inside the groove 27. The guide rail 21 moves downward inside the concrete block 22, and the guide rail 21 squeezes the pressure plate 26 under the action of gravity, so that the pressure plate 26 with a triangular cross section enters the interior of the wire mesh 25. The side wall cross section of the wire mesh 25 has a "Y" shaped structure. When the pressure plate 26 enters the interior of the wire mesh 25, the pressure plate 26 continuously presses the wire mesh 25 towards the reinforcing steel bar 24, while the wire mesh 25 tightly presses the pressure plate 26, fixing the pressure plate 26 to the top of the wire mesh 25. When installing the guide rail 21, multiple laser receivers are placed on the surface of the guide rail 21. When the laser emitter is placed on the ground, the laser emitter emits a rotating laser. The laser receivers receive the signal and transmit the information to the central processing unit. The central processing unit determines whether the top surface of the guide rail 21 is on the same plane. Based on the information sent by the central processing unit, the surface of the guide rail 21 is leveled. The top surface of the guide rail 21 is the reference surface of the ground surface. After the guide rail 21 is installed, the splicing steel bar 23 is tied to the steel cage 11 with steel wire to fix the concrete block 22. After the guide rail 21 and the wire mesh 25 are installed, the concrete pouring area is divided into multiple partitions. When pouring concrete into the partitions, the roller 32 is located on the surface of the guide rail 21 and the device is connected to an external power source.After pouring concrete into the partition, when using a concrete vibrator to compact the concrete, the central processing unit (CPU) operates, causing the third hydraulic rod 52 to retract and push the fixed rod 51 to rotate. The fixed rod 51 drives the fixed plate 53 and the roller 54 to rotate, causing the roller 54 to press tightly against the side wall of the guide rail 21. Simultaneously, the CPU operates, causing the second hydraulic rod 47 to operate, pushing the mounting plate 41 and the vibrating ruler 46 upward. The first hydraulic rod 42 operates, driving the mounting plate 41 and the fixed block 95 downward. The fixed block 95 drives the rubber pad 91 and... The guide rail 21 contacts the rubber pad 91, whose sidewall is arc-shaped. The guide rail 21 presses against the rubber pad 91, pushing the rubber pad 91 and the protrusion 92 to press against the spring 94 and the elastic rod 93. The spring 94 and the elastic rod 93, under pressure, push the rubber pad 91 in the opposite direction to press it tightly against the sidewall of the guide rail 21. When vibrating concrete, the roller 54 and the rubber pad 91 tightly press against the guide rail 21, reducing the shaking of the guide rail 21 and facilitating concrete pouring with the guide rail 21 as a reference surface. Furthermore, the connection between the guide rail 21 and the wire mesh 25 is secured... The pressure plate 26, with a triangular cross-section, is inserted into the wire mesh 25 at one end. Simultaneously, the Y-shaped wire mesh 25, being compressed, moves towards the pressure plate 26, ensuring the top surface of the pressure plate 26 is tightly against the bottom surface of the guide rail 21. This prevents severe grout leakage at the connection between the wire mesh 25 and the guide rail 21. After a section of concrete is vibrated, the first hydraulic rod 42 moves the mounting plate 41 and the fixing block 95 upwards. After the rubber pad 91 separates from the guide rail 21, the second hydraulic rod 47 moves the connecting plate 4... 3. The vibrating leveling ruler 46 moves downward, bringing it into contact with the concrete surface. The motor 33 is turned on, causing the sleeve shaft 35, the rubber ring 34, and the roller 32 to rotate. The roller 32 rolls along the surface of the guide rail 21, thus initially smoothing the concrete surface with the top surface of the guide rail 21 as the reference surface. At the same time, the vibrating motor 45 is turned on, causing the vibrating leveling ruler 46 to vibrate on the concrete surface. As the vibrating leveling ruler 46 moves on the concrete surface, the concrete surface is lifted, leveled, and smoothed.During the operation of the vibratory leveling ruler 46, the tilt sensor 44 detects whether the vibratory leveling ruler 46 is in a horizontal state. When the surface of the vibratory leveling ruler 46 tilts, the second hydraulic rod 47 moves, causing the mounting plate 41 and the vibratory leveling ruler 46 to move up and down, thereby keeping the vibratory leveling ruler 46 in a horizontal state and increasing the flatness of the concrete surface. When smoothing the concrete, the roller 54 moves along the guide rail 21, and at the same time, the roller 54 presses against the guide rail 21, increasing the stability of the guide rail 21. Pouring concrete section by section between the guide rails 21 not only reduces concrete cracks, but also improves the flatness of the concrete surface by smoothing the concrete with the guide rails 21 as a reference surface.
