Description

Technical Field

[0001] This utility model relates to the technical field of PC prefabricated components, and in particular to a precision leveling device for PC prefabricated components used in prefabricated buildings. Background Technology

[0002] PC (precast concrete) construction refers to a construction method in which concrete components are prefabricated and processed in a factory, and then transported to the construction site for assembly. During the assembly of precast PC components, leveling is required, and shims are used to support and fix the components after leveling. Chinese utility model patent CN217897350U discloses a precision leveling device for precast PC components in prefabricated buildings. This leveling device includes a base plate, an adjustment mechanism on the upper side of the base plate, a stabilizing plate on the upper side of the adjustment mechanism, and fixed plates fixedly connected to the upper sides of both ends of the stabilizing plate. A lifting plate is located on the upper side of the fixed plate, a connecting plate is fixedly connected between the two lifting plates, a placement plate is fixedly connected to the upper side of the lifting plate, a clamping mechanism is located on the upper side of the placement plate, and a detection mechanism is located on the front side of the placement plate. In this invention, by providing a sliding groove, a bidirectional screw, a slider, a clamping plate, and a turntable, the PC precast components can be quickly clamped, making it easier for the device to clamp different types of PC precast components, increasing the applicability of the device, and reducing the workload of workers in fixing PC precast components.

[0003] However, the aforementioned leveling device lacks a support and installation mechanism for the shims, which means that after the PC precast components are leveled, the shims need to be manually installed between the PC precast components and the building's support base. Existing technologies typically use shims of different thicknesses, and the PC precast components are supported by a combination of multiple shims. Due to the large weight of the shims, it is not convenient to install the combined shims in place, resulting in high workload. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a precise leveling device for prefabricated PC components of prefabricated buildings, which has a support and installation mechanism with gaskets, making it easier to fill the combined gaskets into place and reducing the workload.

[0005] This utility model discloses a precision leveling device for precast PC components in assembled buildings, comprising a base plate and a clamping mechanism. The clamping mechanism is mounted on the base plate and is used to clamp and support the ends of the precast PC components. It also includes two turntables, two support rods, a vertical shaft, a shim support plate, a threaded seat, and a screw. The two turntables are symmetrically mounted on the left and right sides of the front of the base plate, and the clamping mechanism is located on the left and right sides of the rear of the base plate. The two support rods are slidably mounted on the rotating ends of the two turntables, and the inner ends of the two support rods are rotatably connected to the lower end of the vertical shaft, which is vertically positioned. The shim support plate is rotatably mounted on the vertical shaft and is used to support a shim assembly. The threaded seat is mounted on the shim support plate, which is located above the vertical shaft. The middle part of the screw is rotatably screwed to the threaded seat, and a push plate is mounted on the end of the screw, positioned above the shim support plate. The rotating ends of the two turntables slidably support the two support rods, so that the two turntables, two support rods, vertical shaft, and shim support plate constitute a movable shim support mechanism. During operation, the base plate is fixed. The clamping mechanism is positioned next to the support base of the precast building, clamping and supporting the PC precast component and leveling it. After the PC precast component is leveled, appropriate shims are selected and combined according to the distance between the bottom of the PC precast component and the support base on the building. The shim set is placed on the shim tray, and the shim tray is pushed downwards towards the end of the PC precast component. During this process, two support rods rotate around two turntables, and simultaneously slide and extend relative to the two turntables. This allows the two turntables to support the two support rods, the vertical shaft, and the shim tray, with the shim tray bearing the weight of the shim set. This reduces the workload of the workers. After the shim tray is in place, the screw is rotated, causing the screw to drive the push plate to move towards the shim tray. The push plate pushes the shim set out of the shim tray and fills it between the PC precast component and the support base, thus completing the reliable support of the PC precast component. Compared with existing technologies that have shim support and installation mechanisms, this method makes it easier to fill the combined shims and reduces the workload.

[0006] Preferably, the assembly also includes a vertical rod, a sliding sleeve, and a horizontal rod. The vertical rod is vertically mounted on a threaded seat and has a scale. The sliding sleeve is slidably fitted onto the vertical rod, and a locking screw is rotatably screwed onto the sliding sleeve, locking the sliding sleeve onto the vertical rod. The horizontal rod is mounted on the sliding sleeve. After the PC precast component is leveled, the sliding sleeve is raised and lowered along the vertical rod, causing the sliding sleeve to drive the horizontal rod to rise and fall. The tip of the horizontal rod points to the lower edge of the PC precast component. At this time, the distance between the lower edge of the PC precast component and the support seat is measured by cooperating with the scale on the sliding sleeve and the vertical rod. The tip of the horizontal rod is rotated to the outside of the shim support plate, and suitable shims are selected for assembly. The shim assembly is placed on the base plate, and the top of the shim assembly is aligned with the tip of the horizontal rod, so that the height of the shim assembly matches the distance between the PC precast component and the support seat, achieving the purpose of quickly matching and assembling the shims, which is beneficial to improving work efficiency.

[0007] Preferably, it also includes multiple track wheels, with multiple track wheels rotatably mounted on the rotating ends of both turntables. The multiple track wheels on the turntables are arranged in two rows and symmetrically. Two support rods are respectively arranged between the two rows of track wheels on the two turntables. The two side walls of the two support rods are respectively rolledly connected to the track surfaces of the multiple track wheels. Four track wheels are installed on the rotating ends of both turntables. The four track wheels are arranged in a quadrilateral shape, and the outer wheel surfaces of the four track wheels are provided with limiting grooves. The limiting grooves provide rolling support for the two side walls of the support rods, so that the support rods can extend and retract under the rolling support of the four track wheels, thereby improving the smoothness of the extension and retraction of the support rods.

[0008] Preferably, it also includes multiple chamfers, with chamfers provided at both sides of the two support rods, and the multiple chamfers making rolling contact with the limiting grooves of the multiple track wheels; by providing multiple chamfers, the contact area between the two turntables and the limiting grooves of the multiple track wheels is increased, thereby improving the telescopic stability of the two support rods.

[0009] Preferably, the clamping mechanism includes two push cylinders, two connecting seats, a crossbeam, and a level. The fixed ends of the two push cylinders are respectively installed on the left and right sides of the rear of the base plate. Connecting seats are installed on the top of the piston rods of both push cylinders. Hinges are provided at both ends of the crossbeam, and the hinges of the crossbeam are slidably inserted into the long sliding holes of the two connecting seats. The level is installed on the crossbeam, and a clamping assembly is installed on the crossbeam. The clamping assembly is used to clamp the end of the PC precast component. After the clamping assembly clamps the end of the PC precast component, the piston rod of one push cylinder extends and retracts, pushing the connecting seat on it to rise and fall, so that the connecting seat drives one end of the crossbeam to rise and fall, while the other push cylinder remains stable, thereby... The crossbeam, through a clamping assembly, drives the precast PC component to rotate and level around its axis. A level is used to check the axial leveling result. Once the PC component is axially leveled, the piston rods of the two push cylinders rise and fall synchronously, thereby driving both ends of the crossbeam to rise and fall synchronously through the two connecting seats. This adjusts the height of one end of the PC component, ensuring both ends are at the same height, thus leveling the PC component. The leveling result is checked using a level. Compared to existing technologies that use two push cylinders for axial and horizontal leveling, this method is simpler, easier to operate, and more practical.

[0010] Preferably, the clamping assembly includes two clamping plates and two sliding tables. Each clamping plate is equipped with a sliding table, and the two sliding tables are slidably mounted on the crossbeam. The two clamping plates are arranged opposite each other, and a lower support plate is provided at the lower end of each clamping plate. The two clamping plates are slidably mounted on the left and right sides of the crossbeam respectively via the two sliding tables. The two sliding tables slide relative to each other along the crossbeam, so that the two clamping plates move closer or further apart, thereby enabling the lower support plates of the two clamping plates to hook onto the lower surface of PC precast components of different widths, resulting in stable clamping and good versatility.

[0011] Preferably, it also includes a bearing housing and two screw rods. The bearing housing is installed in the middle of the crossbeam, and the inner ends of the two screw rods are rotatably installed on the left and right sides of the bearing housing, respectively. The middle parts of the two screw rods are rotatably screwed to the two clamping plates. By rotating the two screw rods, the two screw rods and the two clamping plates move the two clamping plates closer or further apart along the crossbeam through the thread action, so that the lower support plates of the two clamping plates hook onto the lower surface of PC precast components of different widths, which is practical.

[0012] Compared with the prior art, the advantages of this utility model are: it has a gasket support and installation mechanism, which makes it easier to install the combined gasket in place and reduces the workload. Attached Figure Description

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0022] Example 1

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a precision leveling device for precast PC components in prefabricated buildings includes a base plate 1 and a clamping mechanism 2. The clamping mechanism 2 is mounted on the base plate 1 and is used to clamp and support the ends of the precast PC components. It also includes two turntables 3, two support rods 4, a vertical shaft 5, a gasket plate 6, a threaded seat 7, and a screw 8. The two turntables 3 are symmetrically mounted on the left and right sides of the front of the base plate 1, and the clamping mechanism 2 is located on the left and right sides of the rear of the base plate 1. The two support rods 4 are slidably mounted on the rotating ends of the two turntables 3, and the inner ends of the two support rods 4 are rotatably connected to the lower end of the vertical shaft 5. The vertical shaft 5 is vertically positioned... The assembly includes a gasket support plate 6 rotatably mounted on a vertical shaft 5, which supports the gasket assembly. A threaded seat 7 is mounted on the gasket support plate 6, which is located above the vertical shaft 5. The middle part of a screw 8 is rotatably screwed to the threaded seat 7, and a push plate is mounted on the end of the screw 8, which is positioned above the gasket support plate 6. The assembly also includes a vertical rod 9, a sliding sleeve 10, and a horizontal rod 11. The vertical rod 9 is vertically mounted on the threaded seat 7 and has a scale. The sliding sleeve 10 is slidably mounted on the vertical rod 9 and has a locking screw rotatably screwed onto it, which locks the sliding sleeve 10 onto the vertical rod 9. The horizontal rod 11 is mounted on the sliding sleeve 10.

[0024] The rotating ends of the two turntables 3 slide to support the two support rods 4, so that the two turntables 3, the two support rods 4, the vertical shaft 5, and the shim support plate 6 form a movable shim support mechanism. During operation, the base plate 1 is fixedly set next to the support seat of the assembled building, so that the clamping mechanism 2 clamps and supports the PC precast component and levels it. After the PC precast component is leveled, appropriate shims are selected and combined according to the distance between the bottom of the PC precast component and the support seat on the building, and the shim group is placed on the shim support plate 6. The shim support plate 6 is pushed downwards towards the end of the PC precast component. During this process, the two support rods 4 rotate around the two turntables 3 respectively, and at the same time, the two support rods 4 slide and extend relative to the two turntables 3 respectively, so that the two turntables 3 support the two support rods 4, the vertical shaft 5, and the shim support plate 6. The shim support plate 6 bears the weight of the shim group, reducing the workload of the workers. After the PC precast component is leveled in place, it is raised and lowered along the vertical rod 9. The sliding sleeve 10 causes the horizontal bar 11 to rise and fall, with the tip of the horizontal bar 11 pointing towards the lower edge of the PC precast component. At this time, the distance between the lower edge of the PC precast component and the support seat is measured by the cooperation of the scale of the sliding sleeve 10 and the vertical bar 9. The tip of the horizontal bar 11 is rotated to the outside of the shim support plate 6, and suitable shims are selected for combination. The shim group is placed on the base plate 1, and the top of the shim group is aligned with the tip of the horizontal bar 11, so that the height of the shim group matches the distance between the PC precast component and the support seat, achieving the purpose of quickly matching and combining the shims. The screw 8 is rotated, causing the screw 8 to drive the push plate to move towards the shim support plate 6, so that the push plate pushes the shim group out of the shim support plate 6 and fills it between the PC precast component and the support seat, completing the reliable support of the PC precast component. Compared with the existing technology with shim support and installation mechanism, it is more convenient to fill the combined shims in place and reduce the labor intensity.

[0025] It also includes multiple track wheels 12, with multiple track wheels 12 rotatably mounted on the rotating ends of both turntables 3. The multiple track wheels 12 on the turntables 3 are arranged in two rows and symmetrically. Two support rods 4 are respectively arranged between the two rows of track wheels 12 on the two turntables 3. The two side walls of the two support rods 4 are respectively in rolling contact with the track surfaces of the multiple track wheels 12. It also includes multiple chamfers 13, with chamfers 13 provided at the two side edges of the two support rods 4. The multiple chamfers 13 are in rolling contact with the limiting grooves of the multiple track wheels 12.

[0026] Four track wheels 12 are installed on the rotating ends of both turntables 3. The four track wheels 12 are arranged in a quadrilateral shape, and the outer wheel surface of the four track wheels 12 is provided with limiting grooves. The limiting grooves provide rolling support to the two side walls of the support rod 4, so that the support rod 4 can extend and retract under the rolling support of the four track wheels 12, thereby improving the smoothness of the extension and retraction of the support rod 4. By setting multiple chamfers 13, the contact area between the two turntables 3 and the limiting grooves of the multiple track wheels 12 is increased, thereby improving the extension and retraction stability of the two support rods 4.

[0027] Example 2

[0028] like Figures 1 to 5 As shown, based on Embodiment 1, the clamping mechanism 2 includes two push cylinders 14, two connecting seats 15, a crossbeam 16, and a level 17. The fixed ends of the two push cylinders 14 are respectively installed on the left and right sides of the rear of the base plate 1. The top of the piston rod of each of the two push cylinders 14 is equipped with a connecting seat 15. Both ends of the crossbeam 16 are provided with hinge shafts, which are slidably inserted into the long sliding holes of the two connecting seats 15. The level 17 is installed on the crossbeam 16, and a clamping assembly is installed on the crossbeam 16. The clamping assembly is used to clamp the PC. The precast component ends; the clamping assembly includes two clamping plates 18 and two slides 19, each clamping plate 18 is equipped with a slide 19, the two slides 19 are slidably mounted on the crossbeam 16 respectively, the two clamping plates 18 are arranged opposite each other, and the lower end of the two clamping plates 18 is provided with a lower support plate; it also includes a bearing seat 20 and two screws 21, the bearing seat 20 is installed in the middle of the crossbeam 16, the inner ends of the two screws 21 are rotatably mounted on the left and right sides of the bearing seat 20 respectively, and the middle parts of the two screws 21 are rotatably screwed to the two clamping plates 18 respectively.

[0029] Rotating the two screws 21 causes the two screws 21 and the two clamping plates 18 to move closer or further apart along the crossbeam 16 via the threaded action. This allows the lower supports of the two clamping plates 18 to hook onto the lower surfaces of PC precast components of different widths. After the two clamping plates 18 clamp the ends of the PC precast components, the piston rod of one push cylinder 14 extends and retracts, pushing the connecting seat 15 on it to rise and fall. This causes the connecting seat 15 to drive one end of the crossbeam 16 to rise and fall, while the other push cylinder 14 remains stable. This allows the crossbeam 16 to move the PC precast components around the axis of the PC precast components via the clamping assembly. The PC precast component is leveled by torsion adjustment. The axial leveling result of the PC precast component is detected by the level 17. After the axial leveling of the PC precast component is completed, the piston rods of the two push cylinders 14 rise and fall synchronously, thereby driving the two ends of the crossbeam 16 to rise and fall synchronously through the two connecting seats 15. This adjusts the height of one end of the PC precast component, making the heights of both ends of the PC precast component the same, thus leveling the PC precast component. The horizontal leveling result of the PC precast component is detected by the level 17. Compared with the existing technology that uses the cooperation of two push cylinders 14 to perform axial and horizontal leveling of PC precast components, the structure is simpler and the operation is more convenient.

[0030] like Figures 1 to 7As shown, this utility model discloses a precision leveling device for precast PC components in assembled buildings. During operation, a base plate 1 is first fixed next to the support of the assembled building. Two screws 21 are rotated, and the two screws 21 and two clamping plates 18, through threaded action, bring the two clamping plates 18 closer together along the crossbeam 16. This causes the lower supports of the two clamping plates 18 to hook onto the lower surfaces of the ends of PC precast components of different widths. Then, the piston rod of one push cylinder 14 extends and retracts, pushing the connecting seat 15 on it to rise and fall. This causes the connecting seat 15 to move one end of the crossbeam 16 up and down, while the other push cylinder 14... To maintain stability, the crossbeam 16, through the clamping assembly, drives the PC precast component to rotate and level around its axis. The axial leveling result of the PC precast component is detected by the level 17. After the PC precast component is axially leveled, the piston rods of the two push cylinders 14 rise and fall synchronously, thereby driving both ends of the crossbeam 16 to rise and fall synchronously through the two connecting seats 15. This adjusts the height of one end of the PC precast component, ensuring that both ends are at the same height, thus leveling the PC precast component. The leveling result of the PC precast component is detected by the level 17. After the PC precast component is leveled... The sliding sleeve 10 is raised and lowered along the vertical rod 9, causing the sliding sleeve 10 to drive the horizontal rod 11 to rise and fall. The tip of the horizontal rod 11 points to the lower edge of the PC precast component. At this time, the distance between the lower edge of the PC precast component and the support base is measured by cooperating with the scale of the sliding sleeve 10 and the vertical rod 9. The tip of the horizontal rod 11 is rotated to the outside of the shim support plate 6. Suitable shims are selected and assembled. The shim assembly is placed on the base plate 1, and the top of the shim assembly is aligned with the tip of the horizontal rod 11, so that the height of the shim assembly matches the distance between the PC precast component and the support base. The shim assembly is then stacked on the shim support plate 6. Finally... Push the gasket plate 6 downwards towards the end of the PC precast component. During this process, the two support rods 4 rotate around the two turntables 3 respectively, and at the same time, the two support rods 4 slide and extend relative to the two turntables 3 respectively, so that the two turntables 3 support the two support rods 4, the vertical shaft 5 and the gasket plate 6. The weight of the gasket assembly is borne by the gasket plate 6, reducing the workload of the workers. After the gasket plate 6 is in place, rotate the screw 8, so that the screw 8 drives the push plate to move towards the gasket plate 6, so that the push plate pushes the gasket assembly out of the gasket plate 6 and fills it between the PC precast component and the support base, thus completing the reliable support of the PC precast component.

[0031] The main functions achieved by this utility model are:

[0032] 1. It has a gasket support and installation mechanism, which makes it easier to install the combined gaskets and reduces the workload;

[0033] 2. The PC precast components are axially and horizontally leveled by the cooperation of two push cylinders 14, which makes the structure simpler and the operation more convenient;
