Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an auxiliary device and construction method for pre-embedded lattice columns. Background Technology

[0002] When multiple internal supports are used for the foundation pit, in order to prevent the first concrete support from deforming excessively due to excessive bending moment, lattice columns must be installed to improve the bending resistance of the support components and ensure the overall stability of the foundation pit support system.

[0003] Patent document CN116537192A discloses an auxiliary system and its construction method for positioning and installing lattice columns. The auxiliary system includes a guide frame and a positioning mechanism. The guide frame can be nested into the lattice column and detachably connected to it. The guide frame includes a positioning frame and multiple first positioning blocks fixed to the outside of the positioning frame. The positioning mechanism controls the center deviation and verticality by adjusting the center deviation and verticality of the guide frame. The positioning mechanism includes a hollow rectangular frame, four jacks installed at the bottom of the four corners of the rectangular frame, and an adjustment mechanism for adjusting the orifice size through which the guide frame passes. The orifice is located within the rectangular frame, and the orifice size matches the size of the positioning frame. The multiple first positioning blocks are located on the rectangular frame and abut against it.

[0004] The above-mentioned device has the following shortcomings: it requires the use of multiple cranes, which is difficult to coordinate, occupies a large area, and takes a long time to operate. In addition, the device is constructed by hoisting and connecting at the same time, which can easily cause the center of gravity to be misaligned with the actual axis line due to hoisting, resulting in instability during connection. Furthermore, the positioning components of the device cannot be recycled and need to be continuously consumed, which causes the lattice columns to support the weight of the positioning components, reducing the load capacity. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems and shortcomings by providing an auxiliary device and construction method for pre-embedded lattice columns, thereby improving overall work efficiency.

[0006] The technical problem solved by this invention is:

[0007] (1) The above-mentioned device requires the use of multiple cranes, which is difficult to coordinate, occupies a large area, and takes a long time to operate.

[0008] (2) The above-mentioned device is installed and connected at the same time. The center of gravity may not coincide with the actual axis line due to the hoisting, and the connection is unstable.

[0009] (3) The positioning components of the above-mentioned device cannot be recycled and need to be consumed continuously, which causes the lattice column to support the weight of the positioning components and reduce the load.

[0010] The objective of this invention can be achieved through the following technical solution: An auxiliary device for pre-embedded lattice columns, comprising a steel cage support member set at the top of a steel cage, a lower support member set at the bottom of the lattice column, an upper support member set at the top of the lattice column, support vertical rods set around the pre-embedded opening, a lifting device fixed at the top of the lattice column, and a horizontal indicator platform. The support vertical rods are vertical and arranged in a circular array of several members. Each support vertical rod is provided with several jacking adjustment members, which are evenly arranged in several layers of circular arrays. The steel cage support members are arranged in a circular array of several members and are all located on the same plane. The plane where the steel cage support members are located is perpendicular to the axis of the steel cage. The lower support member and the upper support member are each arranged in a circular array of several members and are each located on the same plane. The planes where the lower support member and the upper support member are located are both perpendicular to the axis of the lattice column.

[0011] As a further embodiment of the invention, the steel cage support includes a first slide, a first lap block is installed on the movable end of the first slide, a first positioning block is installed on one side of the first slide, and several first clamping blocks arranged in a row at equal intervals are installed on both sides of the first positioning block. A first stud is threaded through the middle of the first clamping block, and each pair of first studs on each side is jointly installed with a first clamping plate. A first nut is threaded onto the end of the first stud closest to the first slide.

[0012] As a further embodiment of the invention, both the lower support and the upper support include a second slide. A second overlapping block is installed at the sliding end of the second slide. A second positioning block is installed on one side of the second slide. Several evenly distributed and parallel coplanar positioning rods are movably inserted through the middle of the second positioning block.

The second positioning block and the adjusting block are both fixedly installed on the positioning rods by positioning bolts. The positioning bolts are threaded through the second positioning block and the adjusting block, respectively, and the positioning bolts abut against the side of the positioning rods.

[0013] As a further embodiment of the invention, a second clamping block is installed on one side of the adjusting block. A double-ended screw is inserted through the middle of the second clamping block and rotatably connected to it. The threads at both ends of the double-ended screw are symmetrical. Vertical clamping blocks are threaded through both ends of the double-ended screw. A second stud is installed at the end of the vertical clamping block closest to the lattice column. A second clamping plate is installed on each pair of second studs. A second nut is threaded onto the second stud. A positioning nut is threaded onto both ends of the double-ended screw. The second nut and the inner wall of the lattice column abut against and clamp the second clamping plate.

[0014] As a further embodiment of the invention, the push adjustment component includes a third slide, a third overlapping block is installed on the movable end of the third slide, a third positioning block is installed on one side of the third slide, the side of the third positioning block abuts against the outer side of the supporting vertical rod, and a number of strip-shaped grooves are provided on the side of the third positioning block. The third positioning block is stably abutted against the supporting vertical rod through the grooves, and the third positioning block makes the axis of the third slide parallel to the supporting vertical rod.

[0015] As a further embodiment of the invention, several third studs are installed on both sides of the third positioning block at equal intervals. Several third clamping plates are installed on both sides of the third studs. Third nuts are threaded onto the third studs, and the third clamping plates and the third positioning block stably clamp the supporting vertical rod through the third nuts.

[0016] As a further aspect of the invention, a T-shaped support platform is installed at the bottom of the supporting vertical rod, and each end of the T-shaped support platform is supported by a diagonal brace to push the supporting vertical rod.

[0017] As a further aspect of the invention, a laser pointer is installed at the lower end of the second slide of the upper support member, and the light emitted by the laser pointer is parallel to the axis of the second slide.

[0018] As a further embodiment of the invention, the horizontal indicator platform includes a fourth slide, which is in a vertical position. A support plate is installed at the bottom of the fourth slide. The axis of the fourth slide is perpendicular to the plane of the support plate. At least three support studs are threaded through the edge of the support plate. The support studs are in a vertical position. A support flat pad is installed at the bottom of the support studs. An indicator plate is installed at the movable end of the fourth slide, and the indicator plate is parallel to the support plate.

[0019] A construction method for an auxiliary device for pre-embedded lattice columns, the method comprising the following steps:

[0020] Step 1: Install steel cage supports on each steel cage to maintain a circular array and ensure they are coplanar.

[0021] Step 2: Install lower and upper supports on each lattice column, with the lower supports at least three meters away from the bottom of the lattice column, maintaining a circular array and coplanarity respectively;

[0022] Step 3: Install support vertical rods at each pre-embedded opening, and install jacking adjustment components on the support vertical rods to maintain the circular array and ensure that they are coplanar;

[0023] Step 4: Hoist the steel cage, overlap the steel cage support components and jacking adjustment components, and then install another layer of jacking adjustment components;

[0024] Step 5: Hoist the lattice column, overlap the lower support and jacking adjustment components, and connect the lattice column and the steel cage after stabilization. At the same time, take advantage of the rapid connection and stable support of the overlap to create a time difference, and hoist the steel cage and lattice column to the adjacent pre-embedded opening.

[0025] Step Six: Hoist the lattice column again, remove the lower support, steel cage support and jacking adjustment components, and lower it until the steel cage touches the bottom;

[0026] Step 7: Reinstall the jacking adjustment component and jack the upper support component. Monitor the vertical status using a laser indicator and a horizontal indicator platform.

[0027] Step 8: Pour and monitor to ensure verticality, and complete the pre-embedding.

[0028] The beneficial effects of this invention are:

[0029] (1) During operation, the jacking adjustment component is connected to the corresponding steel cage support component, lower support component and upper support component respectively. The jacking adjustment component is supported by the support vertical rod, which in turn supports the lattice column and steel cage, thereby calibrating the verticality of the lattice column and steel cage, so that the lattice column and steel cage always remain vertical. This ensures that the lattice column and steel cage remain vertical under adjustment and support during the lowering process, connection process, bottoming process, verticality adjustment process and pouring process. At the same time, the corresponding lap support avoids rotation during hoisting and lowering, reduces the rotation angle, and stabilizes the support during the pouring process, preventing the verticality of the lattice column and steel cage from being affected by the buoyancy of concrete and the expansion and contraction during solidification. During construction, the installation of the jacking adjustment component and the arrangement of the support sequence enable the hoisting equipment to hoist at least two sets of lattice columns and steel cages for pre-embedding and pouring intermittently. This optimizes the time arrangement, shortens the overall working time, improves work efficiency, and reduces vertical and rotational errors.

[0030] (2) When installing the reinforcing cage support, the reinforcing bars on the side wall of the reinforcing cage are clamped and fixed by the first clamping plate and the first positioning block. The first nut and the first stud maintain the thrust on the first clamping plate and the first positioning block, thereby stably installing the first slide onto the outer periphery of the upper end of the reinforcing cage. The reinforcing cage is a standard cylindrical steel structure, so when the axis of the reinforcing cage is vertical, its outer periphery is vertical. The first positioning block and the first slide are both standard cuboid steel structures, so when the side of the first positioning block is stably and tightly attached to the outer periphery of the reinforcing cage, the axis lines of the first positioning block and the first slide are aligned with the reinforcing cage. With the centerlines parallel and the installation stable, the vertical height of the lap surface of the first lap block is accurately adjusted using the first slide table, ensuring that the lap surfaces of the first lap blocks on each steel cage support are coplanar. The symmetrical rotation of the double-ended screw thread causes the vertical clamping blocks to symmetrically close and abut against the upper and lower sides of the lattice column gusset plate. The second nut and second stud cause the second clamping plate and second clamping block to close and abut against the horizontal sides of the lattice column gusset plate, thus ensuring that the centerlines of each component are stably parallel to the centerline of the lattice column, maintaining stable installation. This, in turn, ensures that the adjusting block, positioning rod, and second positioning block are located... The centerlines of all the slides are parallel to the centerline of the lattice column, ensuring that the centerline of the second slide is parallel to the lattice column during operation. This ultimately makes the overlapping surface of the second lap block perpendicular to the centerline of the lattice column, with all lower and upper supports coplanar. This facilitates the quick and easy maintenance of the lattice column and its corresponding centerline in a vertical position. The third slide is then stably installed on the support vertical rod using the third positioning block, third stud, third clamp, and third nut, ensuring that the centerline of the third slide is parallel to the centerline of the support vertical rod. Simultaneously, all third slides are positioned on the same horizontal plane, utilizing the support vertical rod... The third slides are arranged in a circular array, and the precise movement of the third slides makes the overlapping surfaces of the third lap blocks coplanar. This makes the common overlapping surface of the third lap blocks perpendicular to the axis of the steel cage and the lattice column. When the steel cage and the lattice column are lowered, they can be quickly supported by the overlapping of the third lap block and the first lap block, as well as the overlapping of the third lap block and the second lap block. This allows the steel cage and the lattice column to be quickly overlapped and kept vertical, facilitating stable and accurate vertical lowering, corresponding fixed connection, and vertical adjustment upon bottoming out.

[0031] (3) When the reinforcing cage does not touch the bottom, the vertical distance between the second lap block of the upper support and the bottom of the reinforcing cage connected to the lattice column is the fixed length after the lattice column and the reinforcing cage are connected. The height of the lap surface of the third lap block of the jacking adjustment component is the elevation of the lattice column after connection. At this time, the upper support does not need to turn on the laser indicator. The verticality of the lattice column and the reinforcing cage can be quickly calibrated by the corresponding lap of the third lap block and the second lap block. Then, concrete is poured into the pre-embedded opening through the guide pipe, and it is ensured that the lattice column remains stable and does not shake, and the third lap block and the second lap block are tightly connected and do not separate, so as to avoid the concrete pushing the lattice column and causing it to deviate. When the reinforcing cage touches the bottom, the height of each jacking support component is first adjusted on the support vertical rod. Positioning ensures that each third overlapping block stably overlaps with the second overlapping block of the upper support. Then, the laser pointer and horizontal indicator are activated, and each support stud is adjusted to make the support plate horizontal, thereby making the indicator plate horizontal. Then, the indicator plate is positioned directly below the laser pointer. The height of the third overlapping block is adjusted by the third slide, pushing the second overlapping block to adjust the verticality of the lattice column. The laser emitted by the laser pointer to the indicator plate can return and be received by the laser pointer, thus proving that the light is vertical, and further deducing that the lattice column is vertical. Thus, the lattice column is kept vertical through adjustment. All adjustment parts are removed after completion, with no extra parts remaining, and no need to consider additional load requirements.

[0046] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0047] Please see Figure 1-12As shown: An auxiliary device for pre-embedded lattice columns includes a steel cage support 1 set at the top of the steel cage, a lower support 3 set at the bottom of the lattice column, an upper support 5 set at the top of the lattice column, support vertical rods 2 set around the pre-embedded opening, a lifting device 6 fixed at the top of the lattice column, and a horizontal indicator platform 9. The support vertical rods 2 are vertical and arranged in a circular array. Each support vertical rod 2 is provided with several jacking adjustment parts 4. The jacking adjustment parts 4 are evenly arranged in several layers of circular array. The steel cage support 1 is arranged in a circular array and is located on the same plane. The plane where the steel cage support 1 is located is perpendicular to the axis of the steel cage. The lower support 3 and the upper support 5 are each arranged in a circular array and are located on the same plane. The plane where the lower support 3 is located and the plane where the upper support 5 is located are both perpendicular to the axis of the lattice column.

[0048] In this embodiment, the jacking adjustment component 4 is lapped and supported by the corresponding rebar cage support component 1, lower support component 3, and upper support component 5. The jacking adjustment component 4 is supported by the support vertical rod 2, thereby supporting the lattice column and rebar cage. This allows for verticality calibration of the lattice column and rebar cage, ensuring that they remain vertical at all times. This ensures that the lattice column and rebar cage remain vertical under adjustment and support during the lowering, connection, bottoming, verticality adjustment, and pouring processes. Simultaneously, the lapped support prevents rotation during hoisting and lowering, reduces the rotation angle, and provides stable support during pouring, preventing the verticality of the lattice column and rebar cage from being affected by concrete buoyancy and expansion / contraction during solidification. During construction, the installation of the jacking adjustment component 4 and the arrangement of the support sequence allow the hoisting equipment to intermittently hoist at least two sets of lattice columns and rebar cages for pre-embedding and pouring, optimizing the time arrangement, shortening the overall working time, improving work efficiency, and reducing vertical and rotational errors.

[0049] Please see Figure 6 As shown: The steel cage support 1 includes a first slide 101, a first lap block 102 is installed on the movable end of the first slide 101, a first positioning block 107 is installed on one side of the first slide 101, and several first clamping blocks 104 are installed on both sides of the first positioning block 107, arranged in a row at equal intervals. A first stud 105 is threaded through the middle of the first clamping block 104, and a first clamping plate 103 is installed on each pair of first studs 105 on each side. A first nut 106 is threaded onto the end of the first stud 105 near the first slide 101.

[0050] In this embodiment, the reinforcing cage support members 1 are evenly installed in a circular array on the upper outer periphery of the reinforcing cage, with each support member 1 located on the same plane. Simultaneously, the plane containing the support members 1 is perpendicular to the axis of the reinforcing cage. During installation, the reinforcing bars on the sidewalls of the reinforcing cage are clamped and fixed by the first clamping plate 103 and the first positioning block 107. The first nut 106 and the first stud 105 maintain the thrust on the first clamping plate 103 and the first positioning block 107, thereby stably installing the first slide 101 onto the upper outer periphery of the reinforcing cage. Since the reinforcing cage is a standard cylindrical steel structure, its outer periphery is vertical when the axis of the reinforcing cage is vertical. Both the positioning block 107 and the first sliding table 101 are standard cuboid steel structures. Therefore, when the side of the first positioning block 107 is stably and tightly attached to the outer periphery of the reinforcing cage, the center lines of the first positioning block 107 and the first sliding table 101 are parallel to the center line of the reinforcing cage. After stable installation, the vertical height of the lap surface of the first lap block 102 is accurately adjusted by the first sliding table 101, so that the lap surfaces of the first lap blocks 102 on each reinforcing cage support 1 are coplanar, and the plane where the lap surface of the first lap block 102 is located is perpendicular to the center line of the reinforcing cage. During construction, by keeping each first lap block 102 on the same horizontal plane, the reinforcing cage and its center line can be kept vertical quickly and easily.

[0051] Please see Figure 1-4 As shown: Both the lower support 3 and the upper support 5 include a second slide 301. A second overlapping block 302 is installed on the sliding end of the second slide 301. A second positioning block 303 is installed on one side of the second slide 301. Several evenly distributed and parallel coplanar positioning rods 304 are movably inserted through the middle of the second positioning block 303. Adjusting blocks 305 are movably sleeved at both the upper and lower ends of the positioning rods 304. The second positioning block 303 and the adjusting block 305 are both fixedly installed on the positioning rods 304 by positioning bolts 306. The positioning bolts 306 are threaded through the second positioning block 303 and the adjusting block 305 respectively, and the positioning bolts 306 and the side of the positioning rods 304 are respectively threaded through the second positioning block 303 and the adjusting block 305. A second clamping block 307 is installed on one side of the adjusting block 305. A double-ended screw 308 is passed through the middle of the second clamping block 307 and rotatably connected to it. The two ends of the double-ended screw 308 have symmetrical threads. Vertical clamping blocks 309 are threaded through both ends of the double-ended screw 308. A second stud 310 is installed at the end of the vertical clamping block 309 near the lattice column. A second clamping plate 311 is installed on each pair of second studs 310. A second nut 312 is threaded onto the second stud 310. A positioning nut 313 is threaded onto both ends of the double-ended screw 308. The second nut 312 and the inner side wall of the lattice column abut against and clamp the second clamping plate 311.

[0052] In this embodiment, the second clamping block 307, the vertical clamping block 309, and the second clamping plate 311 simultaneously and stably clamp the four sides of the middle part of the horizontal lacing plate of the lattice column, thereby making the axis of the second clamping block 307 and the double-ended screw 308 parallel to the axis of the lattice column. This, in turn, makes the axis of the adjusting block 305, the positioning rod 304, and the second positioning block 303 parallel to the axis of the lattice column. Consequently, the axis of the second slide 301 is parallel to the lattice column during operation, and ultimately, the overlapping surface of the second overlapping block 302 is perpendicular to the axis of the lattice column. Simultaneously, the symmetrical rotation of the double-ended screw 308 causes the vertical clamping block 309 to symmetrically close and abut against the upper and lower sides of the lattice column lacing plate. The second nut 312 and the second stud 310 cause the second clamping plate 311 and the second clamping block 307 to close and abut against the horizontal sides of the lattice column lacing plate, thus ensuring that the axis of each component is stably aligned with the lattice column. The column's axis is kept parallel for stable installation. During installation, the lower support 3 is installed at least three meters away from the bottom of the lattice column, facilitating the insertion of the lower three-meter section of the lattice column into the reinforcing cage. The upper support 5 is installed on the outer periphery of the top of the lattice column according to the design. After installation, the second slide 301 is accurately adjusted to ensure that the overlapping surfaces of each second overlapping block 302 are coplanar and perpendicular to the axis of the lattice column. This ensures that each lower support 3 and each upper support 5 are coplanar, thereby facilitating and quickly keeping the lattice column and its axis vertical. When hoisting only the lattice column or the combined lattice column and reinforcing cage, verticality can be quickly determined by overlapping. Alternatively, the height of the jacking adjustment piece 4 can be adjusted on the support vertical rod 2, and then the vertical height of each lower support 3 or upper support 5 can be adjusted by overlapping and jacking the jacking adjustment piece 4. This allows for multiple methods to determine verticality, ensuring that the lattice column and reinforcing cage remain vertical.

[0053] Please see Figure 1-4 As shown: The push adjustment component 4 includes a third slide 401. A third overlapping block 402 is installed on the movable end of the third slide 401. A third positioning block 406 is installed on one side of the third slide 401. The side of the third positioning block 406 abuts against the outer side of the support vertical rod 2. Several strip-shaped grooves are opened on the side of the third positioning block 406. The third positioning block 406 abuts against the support vertical rod 2 stably through the grooves. The third positioning block 406 makes the axis of the third slide 401 parallel to the support vertical rod 2. Several third studs 403 are installed on both sides of the third positioning block 406. Several third clamping plates 404 are installed on both sides of the third studs 403. A third nut 405 is threaded on the third stud 403. The third clamping plate 404 and the third positioning block 406 stably clamp the support vertical rod 2 through the third nut 405.

[0054] In this embodiment, the supporting vertical rod 2 is first kept vertical, thus keeping its outer periphery vertical. Then, the third slide 401 is stably installed on the supporting vertical rod 2 using the third positioning block 406, the third stud 403, the third clamping plate 404, and the third nut 405, ensuring that the axis of the third slide 401 is parallel to the axis of the supporting vertical rod 2. Simultaneously, all the third slides 401 are located on the same horizontal plane, and the supporting vertical rod 2 is arranged in a circular array to form a circular array of the third slides 401. Then, through... The accurate movement of the third slide 401 makes the overlapping surfaces of each third lap block 402 coplanar, so that the common overlapping surface of each third lap block 402 is perpendicular to the axis of the steel cage and the lattice column. When the steel cage and the lattice column are lowered, they can be quickly supported by the overlapping of the third lap block 402 with the first lap block 102 and the overlapping of the third lap block 402 with the second lap block 302, so that the steel cage and the lattice column can be quickly overlapped and kept vertical, which facilitates the accurate vertical lowering, corresponding fixed connection and vertical adjustment upon contact with the bottom.

[0055] Please see Figure 1-2 As shown: A T-shaped support platform 7 is installed at the bottom of the support vertical rod 2. Each end of the T-shaped support platform 7 is supported by the support vertical rod 2 through the diagonal bracing rod 8. During operation, the ground around the pre-embedded opening is a hardened horizontal ground. The support vertical rod 2 is determined to be vertical by the T-shaped support platform 7 abutting against the horizontal ground, and the support vertical rod 2 is kept stable and vertical by the diagonal bracing rod 8.

[0056] Please see Figure 11-12 As shown: A laser pointer 10 is installed at the lower end of the second slide 301 of the upper support member 5. The light emitted by the laser pointer 10 is parallel to the axis of the second slide 301. The horizontal indicator platform 9 includes a fourth slide 901, which is in a vertical state. A support plate 902 is installed at the bottom of the fourth slide 901. The axis of the fourth slide 901 is perpendicular to the plane of the support plate 902. At least three support studs 903 are threaded through the edge of the support plate 902. The support studs 903 are in a vertical state. A support flat bottom pad 904 is installed at the bottom of the support studs 903. An indicator plate 905 is installed at the movable end of the fourth slide 901. The indicator plate 905 is parallel to the support plate 902.

[0057] During operation, when the rebar cage does not touch the bottom, the vertical distance between the second lap block 302 of the upper support 5 and the bottom of the rebar cage connected to the lattice column is the fixed length after the lattice column and the rebar cage are connected. The height of the lap surface of the third lap block 402 of the jacking adjustment 4 is the elevation of the lattice column after connection. At this time, the upper support 5 does not need to turn on the laser indicator 10. It can directly and quickly calibrate the verticality of the lattice column and the rebar cage by the corresponding lap of the third lap block 402 and the second lap block 302. Then, concrete is poured into the pre-embedded opening through the guide pipe, and the lattice column is kept stable and does not shake. The third lap block 402 and the second lap block 302 are tightly connected and do not separate, thereby avoiding the concrete from pushing the lattice column and causing it to tilt.

[0058] When the steel cage touches the bottom, first adjust the position of each jacking support on the support vertical rod 2 so that each third overlapping block 402 is stably overlapped with the second overlapping block 302 of the upper support 5. Then, activate the laser pointer 10 and the horizontal indicator platform 9, adjust each support stud 903 so that the support plate 902 is horizontal, thereby making the indicator plate 905 horizontal. Then, position the indicator plate 905 directly below the laser pointer 10, adjust the height of the third overlapping block 402 through the third slide 401, and jack the second overlapping block 302 to adjust the verticality of the lattice column. The laser emitted by the laser pointer 10 to the indicator plate 905 can be returned and received by the laser pointer 10, thus proving that the light is vertical, and further deducing that the lattice column is vertical, thereby keeping the lattice column vertical through adjustment.

[0059] A construction method for an auxiliary device for pre-embedded lattice columns, the method comprising the following steps:

[0060] Step 1: Install the rebar cage support 1 evenly in a circular array on the upper outer periphery of the rebar cage, ensuring that each rebar cage support 1 is on the same plane. When installing the rebar cage support 1, the rebar on the side wall of the rebar cage is clamped and fixed by the first clamping plate 103 and the first positioning block 107. The first nut 106 and the first stud 105 maintain the thrust on the first clamping plate 103 and the first positioning block 107, thereby stably installing the first slide table 101 on the upper outer periphery of the rebar cage. After stable installation, the vertical height of the lap surface of the first lap block 102 is accurately adjusted by the first slide table 101, so that the lap surfaces of the first lap blocks 102 on each rebar cage support 1 are coplanar, and the plane where the lap surface of the first lap block 102 is located is perpendicular to the axis of the rebar cage. Arrange for workers to install multiple rebar cages simultaneously.

[0061] Step Two: Install the lower support members 3 in a circular array evenly around the lower outer perimeter of the lattice column. The lower support members 3 should be installed at least three meters from the lower end of the lattice column to facilitate the insertion of the lower three-meter section of the lattice column into the reinforcing cage. Then, install the upper support members 5 in a circular array evenly around the top outer perimeter of the lattice column. During installation, the symmetrical rotation of the double-ended screw 308 causes the vertical clamping blocks 309 to symmetrically close and abut against the upper and lower sides of the lattice column gusset plate. The second nut 312 and the second stud 310 cause the second clamping plate 311 and the second clamping block 307 to close and abut against the horizontal sides of the lattice column gusset plate. The second clamping block 307, the vertical clamping block 309, and the second clamping plate 311 then support the four sides of the horizontal gusset plate in the middle of the lattice column. Simultaneously, the surrounding sides are stably clamped against each other, so that the axis of the second clamping block 307 and the double-headed screw 308 are parallel to the axis of the lattice column. This makes the axis of the adjusting block 305, the positioning rod 304 and the second positioning block 303 parallel to the axis of the lattice column. This makes the axis of the second slide 301 parallel to the lattice column when it is working. Finally, the overlapping surface of the second overlapping block 302 is perpendicular to the axis of the lattice column, so that the axis of each component is stably parallel to the axis of the lattice column. Then, the accurate movement of the second slide 301 makes the overlapping surfaces of each second overlapping block 302 coplanar, allowing workers to install multiple lattice columns at the same time.

[0062] Step 3: Set up several support vertical rods 2 around the pre-embedded opening, so that the support vertical rods 2 are evenly distributed in a ring array with the axis of the pre-embedded opening as the axis. Then keep the support vertical rods 2 stable and vertical. Then, install a layer of push adjustment parts 4 evenly distributed in a ring array on the support vertical rods 2 at the lower part of the support vertical rods 2 near the pre-embedded opening and in a position that is convenient for workers to connect the lattice column and the steel cage. During installation, the third slide 401 is stably installed on the support vertical rod 2 by the third positioning block 406, the third stud 403, the third clamping plate 404 and the third nut 405, so that the axis of the third slide 401 is parallel to the axis of the support vertical rod 2, and at the same time, all the third slides 401 are located on the same horizontal plane. Then, through the accurate movement of the third slide 401, the overlapping surfaces of all the third overlapping blocks 402 are coplanar. The above installation is performed in multiple adjacent pre-embedded openings.

[0063] Step 4: First, lower the steel cage equipped with the steel cage support 1 onto the pre-embedded opening with the jacking adjustment component 4 using a crane. Align the third lap block 402 of the jacking adjustment component 4 with the first lap block 102 of the steel cage support 1, thereby ensuring that the axis of the steel cage remains vertical and that the steel cage is coaxial with the pre-embedded opening. Then, separate the crane from the steel cage and install another layer of jacking adjustment components 4 evenly distributed in a circular array on the support vertical rod 2, ensuring that the lap surfaces of each third lap block 402 are coplanar.

[0064] Step 5: After the crane lifts the lattice column using the lifting device 6, it lifts the lattice column equipped with the lower support 3 and the upper support 5 to the top of the rebar cage. The lattice column is then connected to the rebar cage and inserted into the rebar cage to a depth of three meters. The second lap block 302 and the third lap block 402 of the lower support 3 are accurately fitted together, ensuring that the lattice column and the rebar cage are coaxial and that the axis of the lattice column is stable and vertical. At the same time, the rapid connection and stable support of the lap create a time difference. After the lap is completed, the lattice column is stably stopped above the pre-embedded opening. The crane is then separated from the lifting device 6. While the workers are connecting the lattice column and the rebar cage, the crane lifts the rebar cage and lattice column on the adjacent pre-embedded opening. The rebar cage and lattice column are installed simultaneously in a controlled manner at both pre-embedded openings, shortening the interval between the connection of the lattice column and the rebar cage on the adjacent pre-embedded openings and shortening the construction period.

[0065] Step 6: After the lattice column and the steel cage are connected, the crane lifts the lattice column and the steel cage through the lifting device 6, so that the lower support 3 and the steel cage support 1 are separated from the corresponding jacking adjustment device 4 respectively. Then the lower support 3 and the steel cage support 1 are removed and reused. At the same time, the jacking adjustment device 4 is removed. Then the lattice column and the steel cage are lowered until the steel cage touches the bottom.

[0066] Step 7: Then, install the jacking adjustment component 4 on the support rod 2 below the upper support component 5, and make the third overlapping block 402 of the jacking adjustment component 4 stably overlap with the second overlapping block 302 of the upper support component 5. Then, start the laser pointer 10 and the horizontal indicator platform 9, adjust each support stud 903 to make the support plate 902 horizontal, so that the indicator plate 905 is horizontal. Then, place the indicator plate 905 directly below the laser pointer 10, adjust the height of the third overlapping block 402 through the third slide 401, and jack the second overlapping block 302 to adjust the verticality of the lattice column. The laser emitted by the laser pointer 10 to the indicator plate 905 can be returned and received by the laser pointer 10, thus proving that the light is vertical, and further deducing that the lattice column is vertical. Thus, the lattice column is kept vertical by adjustment. The crane can either assist the jacking adjustment component 4 to provide part of the support force for quick adjustment, or adjust only through the jacking adjustment component 4. The crane can carry out hoisting construction on adjacent pre-embedded openings to shorten the construction period.

[0067] Step 8: Install a conduit into the pre-embedded opening and pour concrete. Monitor the swaying of the lattice column during pouring using a laser indicator 10, and ensure that the lattice column remains vertical using a jacking adjustment component 4, thus completing the pre-embedding of one lattice column.

[0068] In use, the present invention allows workers to use the jacking adjustment component 4 to overlap and support the corresponding steel cage support component 1, lower support component 3, and upper support component 5. The jacking adjustment component 4 is supported by the support vertical rod 2, thereby supporting the lattice column and steel cage. This allows for verticality calibration of the lattice column and steel cage, ensuring that they remain vertical at all times. This ensures that the lattice column and steel cage remain vertical under adjustment and support during the lowering, connection, bottoming, verticality adjustment, and pouring processes. Simultaneously, the overlapping support prevents rotation during hoisting and lowering, reduces the rotation angle, and provides stable support during pouring, preventing the verticality of the lattice column and steel cage from being affected by concrete buoyancy and expansion / contraction during solidification. During construction, the installation of the jacking adjustment component 4 and the arrangement of the support sequence allow the hoisting equipment to intermittently hoist at least two sets of lattice columns and steel cages for pre-embedding and pouring, thus optimizing the time arrangement, shortening the overall working hours, improving work efficiency, and reducing vertical and rotational errors.

[0069] When installing the rebar cage support 1, the rebar on the side wall of the rebar cage is clamped and fixed by the first clamping plate 103 and the first positioning block 107. The first nut 106 and the first stud 105 maintain the thrust that abuts against the first clamping plate 103 and the first positioning block 107, thereby stably installing the first slide 101 onto the outer periphery of the upper end of the rebar cage. The rebar cage is a standard cylindrical steel structure, so when the axis of the rebar cage is vertical, its outer periphery is vertical. Both the first positioning block 107 and the first slide 101 are standard cuboid steel structures, so when the side of the first positioning block 107 is stably and tightly attached to the outer periphery of the rebar cage, the axis of each of the first positioning block 107 and the first slide 101 is aligned with the steel cage. After the centerlines of the reinforcing cages are parallel and stably installed, the vertical height of the lap surface of the first lap block 102 is accurately adjusted by the first slide table 101, so that the lap surfaces of the first lap blocks 102 on each reinforcing cage support 1 are coplanar. The symmetrical rotation of the threads of the double-ended screw 308 causes the vertical clamping blocks 309 to symmetrically close and abut against the upper and lower sides of the lattice column gusset plate. The second nut 312 and the second stud 310 cause the second clamping plate 311 and the second clamping block 307 to close and abut against the horizontal sides of the lattice column gusset plate, so that the centerlines of each component are stably parallel to the centerline of the lattice column, maintaining stable installation. This, in turn, ensures that the adjusting block 305, the positioning rod 304, and the first The centerlines of the two positioning blocks 303 are parallel to the centerline of the lattice column, thus ensuring that the centerline of the second slide 301 is parallel to the lattice column during operation. This results in the overlapping surface of the second overlapping block 302 being perpendicular to the centerline of the lattice column, with all lower support members 3 and upper support members 5 being coplanar. This facilitates the quick and easy maintenance of the lattice column and its centerline. The third slide 401 is then stably installed on the support rod 2 using the third positioning block 406, third stud 403, third clamping plate 404, and third nut 405, ensuring that the centerline of the third slide 401 is parallel to the centerline of the support rod 2, and that all third slides 401 are located on the same horizontal plane. The support vertical rods 2 are arranged in a circular array so that the third slides 401 are arranged in a circular array. Then, the accurate movement of the third slides 401 makes the overlapping surfaces of the third lap blocks 402 coplanar, so that the common overlapping surface of the third lap blocks 402 is perpendicular to the axis of the steel cage and the lattice column. When the steel cage and the lattice column are lowered, they can be quickly supported by the overlapping of the third lap block 402 with the first lap block 102 and the overlapping of the third lap block 402 with the second lap block 302, so that the steel cage and the lattice column can be quickly overlapped and kept vertical, which facilitates the accurate vertical lowering, corresponding fixed connection and vertical adjustment upon bottoming.

[0070] When the reinforcing cage does not touch the bottom, the vertical distance between the second lap block 302 of the upper support 5 and the bottom of the reinforcing cage connected to the lattice column is the fixed length after the lattice column and the reinforcing cage are connected. The height of the lap surface of the third lap block 402 of the jacking adjustment component 4 is the elevation of the lattice column after connection. At this time, the upper support 5 does not need to turn on the laser indicator 10. It can directly and quickly calibrate the verticality of the lattice column and the reinforcing cage by the corresponding lap of the third lap block 402 and the second lap block 302. Then, concrete is poured into the pre-embedded opening through the guide pipe, and it is ensured that the lattice column remains stable and does not shake, and that the third lap block 402 and the second lap block 302 are tightly connected and do not separate, so as to avoid the concrete pushing the lattice column and causing it to tilt. When the reinforcing cage touches the bottom, it is first adjusted on the support vertical rod 2. The positions of each jacking support are adjusted so that each third overlapping block 402 is stably connected to the second overlapping block 302 of the upper support 5. Then, the laser pointer 10 and the horizontal indicator platform 9 are activated, and each support stud 903 is adjusted so that the support plate 902 is horizontal, thereby making the indicator plate 905 horizontal. Then, the indicator plate 905 is positioned directly below the laser pointer 10. The height of the third overlapping block 402 is adjusted by the third slide 401, and the second overlapping block 302 is jacked up, thereby adjusting the verticality of the lattice column. The laser emitted by the laser pointer 10 to the indicator plate 905 can be reflected back and received by the laser pointer 10, thus proving that the light is vertical, and further deducing that the lattice column is vertical, thereby keeping the lattice column vertical through adjustment.
