Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a lattice column correction device and method. Background Technology

[0002] In building construction, due to space constraints and other factors, there is often no large area available for temporary roads during the underground structure construction phase to facilitate material transportation and structural pouring. Therefore, trestle areas are commonly designed for vehicular traffic. To meet load-bearing requirements, lattice columns are typically inserted into the engineering piles beneath the trestle, reinforced with longitudinal and transverse channel steel scissor bracing to increase load-bearing capacity. However, current trestle areas are generally lower than existing road surfaces. Once the lattice columns are inserted below the road surface or mud level, it is difficult to observe their position and verticality. On-site monitoring often struggles to ensure overall verticality and positional deviations, leading to inaccurate column positioning and tilting. This negatively impacts the quality of scissor bracing welding, increasing the risk of safety accidents. Current construction techniques do not consider the verticality, horizontal angle, and positioning of the lattice columns after they are submerged in mud or ground level, which is detrimental to construction safety and quality. Summary of the Invention

[0003] The purpose of this invention is to provide a lattice column correction device and method to solve the problem of how to correct the verticality and horizontal angle of lattice columns.

[0004] To solve the above-mentioned technical problems, the present invention provides a lattice column correction device, comprising:

[0005] A verticality correction component includes a horizontally arranged top plate, four side plates arranged in a rectangular array on the same horizontal plane with the vertical center line of the top plate as the center, parallel to the bottom of the top plate, and four flexible adjustment ropes vertically connected between the four corners of the top plate and the corresponding side plates. A first hydraulic cylinder is provided between two adjacent side plates. The extension and retraction of the four side plates relative to the vertical center line of the top plate are adjusted by controlling the extension and retraction of each first hydraulic cylinder. Each side plate is provided with two second hydraulic cylinders parallel to the first hydraulic cylinder on its side and located inside it. Each second hydraulic cylinder is connected to a fastening clamp plate. The fastening clamp plate is a right-angle plate. The plate body of the fastening clamp plate parallel to the second hydraulic cylinder is provided with a blind groove for installing the lacing plate of the lattice column and a longitudinal through groove for installing the corner plate of the lattice column. The blind groove and the longitudinal through groove are interconnected.

[0006] Furthermore, the lattice column correction device provided by the present invention includes an upper connecting rope disposed on the top plate and a lower connecting rope disposed on the side plate, as well as a bidirectional threaded sleeve connecting the upper connecting rope and the lower connecting rope at the same corner position. The length of the flexible adjusting rope can be adjusted by rotating the bidirectional threaded sleeve.

[0007] Furthermore, the lattice column correction device provided by the present invention also includes a central controller, which is connected to an operation panel and four position sensors, which are disposed on the corners of the four side plates or on the four corners of the same plane at the top of the lattice column.

[0008] Furthermore, the lattice column correction device provided by the present invention includes a right-angled plate with a stepped hypotenuse, formed by alternating horizontal and vertical cuts along two inner sides of a rectangular plate. The stepped surface includes a first end face, a third end face, a fifth end face, and a seventh end face that are parallel to the first outer side of the right-angled plate and are sequentially tapered, and a second end face, a fourth end face, a sixth end face, and an eighth end face that are parallel to the second outer side of the right-angled plate and are sequentially tapered. Two second hydraulic cylinders on each side plate are respectively vertically arranged on the third end face and the sixth end face. The included angle of the fastening clamps is distributed towards the stepped surface of the side plate.

[0009] To address the aforementioned technical problems, the present invention also provides a method for correcting lattice columns, employing the aforementioned lattice column correction device, comprising:

[0010] By controlling the extension and retraction of each first hydraulic cylinder, each side plate unfolds outward with the vertical center line of the top plate as the center, so that the lattice column correction device can be fitted onto the lattice column through the central opening after the four side plates have unfolded. By controlling the extension and retraction of each first hydraulic cylinder, each side plate retracts inward with the vertical center line of the top plate as the center. At the same time, by controlling the extension and retraction of each second hydraulic cylinder, the blind groove of the fastening clamp is assembled on the lower end face of the lacing plate in the corresponding direction of the lattice column, and the longitudinal through groove of the fastening clamp is assembled on one side plate of the corner plate in the corresponding direction of the lattice column, so that the lattice column correction device and the lattice column are clamped and fixedly connected by the fastening clamp.

[0011] By using lifting slings or setting lifting rings on the top slab, and connecting the lifting equipment by passing the lifting rope through the lifting rings, the lifting equipment is started and the lattice column correction device and the connected lattice column are lifted synchronously by using lifting slings or lifting ropes, and the lattice column is aligned with the steel cage exposed on the ground of the pile hole and lowered.

[0012] Measure the coordinate data of the four corners of the plane where the top of the lattice column is located relative to the ground, or measure the coordinate data of the four corners of each side plate relative to the ground. Determine the direction of the deviation of the verticality of the lattice column by the coordinate data of the four corners, and correct the verticality of the lattice column by adjusting the length of the flexible adjustment rope on the side where the deviation direction is located.

[0013] The verticality-corrected lattice columns are welded onto the steel cage;

[0014] The lattice column correction device and the lattice column and the welded steel cage are hoisted and lowered into the pile hole simultaneously. During the lowering process, the verticality of the lattice column and the steel cage in the pile hole is adjusted and corrected by adjusting the length of each flexible adjustment rope.

[0015] Furthermore, the lattice column correction method provided by the present invention, when the horizontal angle of the lattice column is deviated by judging from the coordinate data of the four corners before and after the welding of the lattice column, corrects the horizontal angle of the lattice column by rotating the verticality correction component.

[0016] Furthermore, the lattice column correction device provided by the present invention further includes:

[0017] A horizontal angle correction component includes a horizontally arranged lower hanging plate, an upper hanging plate parallel to the lower hanging plate, multiple evenly distributed vertical columns vertically connected between the upper and lower hanging plates, and a rotating shaft vertically arranged between the lower hanging plate and the top plate of the verticality correction component for rotatable connection.

[0018] Furthermore, the lattice column correction device provided by the present invention further includes a central controller disposed on the upper surface of the lower hanging plate. The central controller is connected to an operation panel and includes four position sensors disposed on the corners of the four side plates or on the four corners of the same plane near the upper end face of the lattice column.

[0019] To address the aforementioned technical problems, the present invention also provides a method for correcting lattice columns, employing the aforementioned lattice column correction device, comprising:

[0020] By controlling the extension and retraction of each first hydraulic cylinder, each side plate unfolds outward with the vertical center line of the top plate as the center, so that the lattice column correction device can be fitted onto the lattice column through the central opening after the four side plates have unfolded. By controlling the extension and retraction of each first hydraulic cylinder, each side plate retracts inward with the vertical center line of the top plate as the center. At the same time, by controlling the extension and retraction of each second hydraulic cylinder, the blind groove of the fastening clamp is assembled on the lower end face of the lacing plate in the corresponding direction of the lattice column, and the longitudinal through groove of the fastening clamp is assembled on one side plate of the corner plate in the corresponding direction of the lattice column, so that the lattice column correction device and the lattice column are clamped and fixedly connected by the fastening clamp.

[0021] By using lifting slings or setting lifting rings on the upper lifting plate, and connecting the lifting equipment by passing the lifting rope through the lifting rings, the lifting equipment is started and the lattice column correction device and the connected lattice column are lifted simultaneously by the lifting slings or lifting ropes, and the lattice column is aligned with the steel cage exposed on the ground of the pile hole and lowered.

[0022] Measure the coordinate data of the four corners of the plane where the top of the lattice column is located relative to the ground, or measure the coordinate data of the four corners of each side plate relative to the ground. Determine the direction of the vertical deviation and the direction of the horizontal angle deviation of the lattice column by using the coordinate data of the four corners. Correct the verticality of the lattice column by adjusting the length of the flexible adjustment rope on the side where the deviation direction is located. Correct the horizontal angle of the lattice column by rotating the verticality correction component and keeping the horizontal angle correction component stationary by rotating the shaft.

[0023] The vertical and horizontal angle corrected lattice columns are welded onto the steel cage;

[0024] The lattice column correction device, the lattice column and its welded steel cage are hoisted and lowered into the pile hole simultaneously. During the lowering process, the verticality of the lattice column and steel cage in the pile hole is corrected by adjusting the length of each flexible adjustment rope, and the horizontal angle of the lattice column is corrected by rotating the verticality correction component and keeping the horizontal angle correction component stationary by rotating the shaft.

[0025] Furthermore, the lattice column correction method provided by the present invention uses external instruments or a position sensor set on the vertical center line of the lattice column to measure the deviation distance between the coordinates of the vertical center line of the lattice column and the center coordinates of the pile hole during the synchronous hoisting of the lattice column and its connected steel cage. This method corrects the positioning of the lattice column and the steel cage within the pile hole.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] The lattice column correction device and method provided by the present invention connect the lattice column correction device to the lattice column, and use the lattice column correction device to hoist and lower the lattice column and its connected steel cage. During the hoisting process, the verticality of the lattice column is corrected by adjusting the length of each flexible adjustment rope, and the horizontal angle of the lattice column is corrected by rotating the verticality correction component to drive the lattice column to rotate. This improves the installation accuracy, construction quality and safety of the lattice column and steel cage. Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0036] Example 1

[0037] Please refer to Figures 1 to 3 This invention provides a lattice column correction device 100 and method. The device includes a verticality correction component, which includes a horizontally arranged top plate 109, four side plates 101 arranged in a rectangular array on the same horizontal plane parallel to the bottom of the top plate 109 and centered on the vertical center line of the top plate 109, four flexible adjustment ropes vertically connected between the four corners of the top plate 109 and the corresponding side plates 101, and a first hydraulic cylinder 102 disposed between two adjacent side plates 101. The extension and retraction of each of the first hydraulic cylinders 102 controls the adjustment of the four side plates 101. 1. The verticality correction assembly expands or contracts relative to the vertical centerline of the top plate 109. Each side plate 101 is equipped with two second cylinders 103 parallel to the first cylinder 102 on its side and located inside it. Each second cylinder 103 is connected to a fastening clamp 104. The fastening clamp 104 is a right-angle plate. The fastening clamp 104, parallel to the second cylinder 103, is provided with a blind groove 104a for installing the gusset plate 202 of the lattice column 200 and a longitudinal through groove 104b for installing the corner plate 201 of the lattice column 200. The blind groove 104a and the longitudinal through groove 104b are interconnected. That is, the verticality correction assembly consists of four side plates 101, four first cylinders 102, eight second cylinders 103, eight fastening clamps 104, and one top plate 109.

[0038] Embodiment 1 of the present invention also provides a method for correcting lattice columns, which, using the above-described lattice column correction device 100, may include the following steps:

[0039] In step S301, the extension and retraction control of each of the first hydraulic cylinders 102 causes each side plate 101 to unfold outward with the vertical center line of the top plate 109 as the center, so that the lattice column correction device 100 is fitted onto the lattice column 200 through the central opening after the four side plates 101 have unfolded. Specifically, the central opening after the four side plates 101 have unfolded is fitted onto the lattice column 200, and the extension and retraction control of each of the first hydraulic cylinders 102 causes each side plate 101 to unfold outward with the vertical center line of the top plate 109 as the center, so that the four side plates 101 have unfolded outward with the vertical center line of the top plate 109 as the center, so that the four side plates 101 have unfolded outward with the central opening ... The straight centerline contracts inward, and the extension and retraction control of each second hydraulic cylinder 103 causes the blind groove 104a of the fastening clamping plate 104 to be assembled onto the lower end face of the lacing plate 202 in the corresponding direction of the lattice column 200, and the longitudinal through groove 104b of the fastening clamping plate 104 to be assembled onto one side plate of the corner plate 201 in the corresponding direction of the lattice column 200, so that the lattice column correction device 100 and the lattice column 200 are clamped and fixedly connected by the fastening clamping plate 104. The lattice column 200 is assembled from four rectangularly distributed corner plates 201 and multiple lacing plates 202 welded between adjacent corner plates 201. The lacing plates 202 in each direction of the lattice column 200 are assembled by two fastening clamps 104. That is, each lacing plate 202 is engaged or clamped to the blind groove 104a of the two fastening clamps 104. The side plates of each corner plate 201 in two directions are assembled by one fastening clamp 104. That is, the longitudinal through groove 104b of each fastening clamp 104 clamps one side plate of the corner plate 201 of the lattice column 200. Combined with the pressing of each first hydraulic cylinder 102 and each second hydraulic cylinder 103, the fastening clamps 104 are kept clamped and fixed to the lattice column 200, thus realizing the stable connection between the lattice column correction device 100 and the lattice column 200.

[0040] In step S302, a lifting device such as a tower crane or truck crane is connected by a lifting belt or a lifting ring (not shown) set on the top plate 109 and a lifting rope (not shown) passing through the lifting ring. The lifting device is started to lift the lattice column correction device 100 and the lattice column 200 connected thereto simultaneously by the lifting belt or the lifting rope, and the lattice column 200 is lowered with the steel cage (not shown) exposed on the ground of the pile hole aligned with it.

[0041] Step S303: Measure the coordinate data of the four corners of the plane containing the upper end of the lattice column 200 relative to the ground, or measure the coordinate data of the four corners of each side plate 101 relative to the ground. Determine the direction of the verticality deviation of the lattice column 200 based on the coordinate data of the four corners, and correct the verticality of the lattice column 200 by adjusting the length of the flexible adjustment rope on the side where the deviation direction is located. At this time, the coordinate data can be measured using measuring instruments such as a 3D laser scanner or a position sensor.

[0042] Step S304: Weld the verticality-corrected and horizontal angle-corrected lattice column 200 onto the steel cage.

[0043] In step S305, the lattice column correction device 100 and its connected lattice column 200 and welded steel cage are simultaneously hoisted and lowered into the pile hole (not shown). During the lowering process, the verticality of the lattice column 200 and steel cage in the pile hole is adjusted and corrected by adjusting the length of each flexible adjustment rope.

[0044] Please refer to Figures 1 to 3 The lattice column correction device 100 and method provided in Embodiment 1 of the present invention include a flexible adjusting rope comprising an upper connecting rope 108 disposed on the top plate 109 and a lower connecting rope 106 disposed on the side plate 101, and a bidirectional threaded sleeve 107 connecting the upper connecting rope 108 and the lower connecting rope 106 at the same corner position. The length of the flexible adjusting rope can be adjusted by rotating the bidirectional threaded sleeve 107. The bidirectional threaded sleeve 107 can control the synchronous elongation or shortening of the upper connecting rope 108 and the lower connecting rope 106 by clockwise or counterclockwise rotation. Both the upper and lower connecting ropes can be steel wire ropes, and both the upper connecting rope 108 and the lower connecting rope 106 are provided with external threads matching the bidirectional threaded sleeve 107. Of course, the flexible adjusting rope is not limited to this structure and can also be other flexible connection structures. The flexible adjustment rope allows the four side plates 101 to expand or contract relative to the vertical center line of the top plate 109 under the telescopic control of the four first oil cylinders 102. This achieves the connection between the verticality correction component and the lattice column 200, and also enables the applicability of lattice columns 200 of different specifications and sizes, thus having the advantage of wide applicability.

[0045] Please refer to Figures 1 to 3 To determine the verticality deviation of the lattice column 200, the lattice column correction device 100 and method provided in Embodiment 1 of the present invention further includes a central controller 114. The central controller 114 is connected to an operation panel 115, which can be a regular panel with a physical keyboard and display, or a touch panel. It also includes four position sensors 105, such as GPS and gyroscopes, located at the corners of the four side plates 101 or at the four corners of the lattice column 200 on the same plane at the top. The four position sensors 105 detect the coordinate data of the four side plates 101 or the lattice column 200 on the same horizontal plane and feed it back to the central controller 114. The central controller 114 determines the direction and distance of the verticality deviation of the lattice column 200 based on the elevation data in the coordinate data of the four corners and displays it on the display screen of the operation panel 115.

[0046] Please refer to this carefully. Figures 3 to 4The lattice column correction device 100 and method provided in Embodiment 1 of the present invention, wherein the side plate 101 is an integral structure formed by alternating horizontal and vertical cuts of a rectangular plate along its two inner sides, with the hypotenuse of the corner plate 201 being a stepped surface. Specifically, the side plate 101 can be an integral structure formed by alternating horizontal and vertical cuts of a rectangular plate along its two inner sides, wherein the horizontal and vertical cuts are performed alternately, with three horizontal cuts and three vertical cuts; the stepped surface includes the first outer side 101i parallel to the corner plate 201 in sequence. The first end face 101a, the third end face 101c, the fifth end face 101e, the seventh end face 101g, and the second end face 101b, the fourth end face 101d, the sixth end face 101f, and the eighth end face 101h, which are parallel to the second outer side face 101j of the corner plate 201, are sequentially contracted. Two second hydraulic cylinders 103 on each side plate 101 are respectively vertically disposed on the third end face and the sixth end face. The included angle of the fastening clamps 104 is distributed towards the stepped surface of the side plate 101. The side plate 101 is a one-piece structure, which improves its structural strength and stability. The inclined edges (i.e., the two inner surfaces) of the side plates 101 form stepped surfaces, making the arrangement of the four side plates 101 more compact and smaller in size. This reduces the stroke length requirement of the first hydraulic cylinder 102, thus lowering costs. Furthermore, it provides space for the assembly of the second hydraulic cylinder 103, also reducing its stroke length requirement. Additionally, it provides greater adjustment space for the fastening clamp 104 to extend and retract under the control of the second hydraulic cylinder 103, enabling precise assembly of the fastening clamp 104 with the lattice column 200 and accommodating the assembly of lattice columns 200 of different sizes. To improve the reliability of the extension and retraction control of the fastening clamp 104, each fastening clamp 104 can be equipped with two second hydraulic cylinders 103.

[0047] The lattice column correction method provided in Embodiment 1 of this invention allows for the determination of horizontal angle deviations in the lattice column 200 before and after welding (i.e., before and after step S104) by using the coordinate data of its four corners. Specifically, the central controller 114 calculates the horizontal deviation angle between the coordinate data of the four corners and the vertical centerline of the lattice column 200 (i.e., the vertical centerline of the pile hole). After verticality correction, the horizontal angle deviation can be determined by the angle between the coordinate data of one corner and the vertical centerline. Then, the horizontal angle of the lattice column 200 is corrected by rotating the verticality correction component. When the lattice column 200 is welded to the reinforcing cage, the horizontal angle does not need adjustment if the deviation is small. However, the horizontal angle deviation caused during the lowering of the reinforcing cage into the pile hole necessitates adjustment.

[0048] It should be noted that, since there is a reserved distance between the lower end of the reinforcing cage and the bottom of the pile hole, that is, the reinforcing cage is suspended in the pile hole and does not contact the bottom of the pile hole, the horizontal angle of the lattice column 200 can be corrected by rotating the verticality correction component. Also, since the reinforcing cage is suspended in the pile hole, a flexible adjustment rope can be used.

[0049] The lattice column correction device 100 and method provided in Embodiment 1 of the present invention connect the lattice column correction device 100 to the lattice column 200. The lattice column correction device 100 is used to hoist and lower the lattice column 200 and its connected steel cage. During the hoisting process, the verticality of the lattice column 200 is corrected by adjusting the length of each flexible adjusting rope. The horizontal angle of the lattice column 200 is corrected by rotating the verticality correction component to drive the lattice column 200 to rotate. This improves the installation accuracy of the lattice column 200 and the steel cage, and improves the construction quality and safety of the lattice column 200 and the steel cage.

[0050] Example 2

[0051] Please refer to Figures 1 to 3 Embodiment 2 of the present invention provides a lattice column correction device 100, which is an improvement on Embodiment 1, the difference being that it further includes:

[0052] A horizontal angle correction assembly includes a horizontally arranged lower hanging plate 111, an upper hanging plate 113 parallel to the lower hanging plate 111, multiple evenly distributed vertical columns 112 vertically connected between the upper hanging plate 113 and the lower hanging plate 111, and a rotating shaft 110 vertically arranged and rotatably connected between the lower hanging plate 111 and the top plate 109 of the verticality correction assembly. Both the upper and lower hanging plates can be rectangular plates, and the vertical columns 112 are rigid connecting columns such as steel columns. One end of the rotating shaft 110 can be fixedly set on the lower surface of the vertical center line of either the lower hanging plate 111 or the top plate 109, and the other end of the rotating shaft 110 can be rotatably set on the upper surface of the remaining vertical center line of either the top plate 109 or the lower hanging plate 111, wherein the vertical center lines of the lower hanging plate 111 and the top plate coincide, and the two ends of the rotating shaft 110 are respectively rotatably set on the vertical center lines of the top plate 109 and the lower hanging plate 111. The rotating shaft 110 can be rotatably mounted on the top plate 109 and / or the lower hanging plate 111 via bearings.

[0053] Please refer to Figures 1 to 3 To protect the central controller 114, the lattice column correction device 100 provided in Embodiment 2 of the present invention has the central controller 114 disposed on the upper surface between the lower hanging plate 111 and the upper hanging plate 113 of the horizontal angle correction component. To improve the stability of the central controller 114 during the hoisting and lowering of the lattice column 200, the central controller 114 can be fixedly mounted on the upper hanging plate 113 and the lower hanging plate 111 respectively.

[0054] Embodiment 2 of the present invention also provides a method for correcting lattice columns, which uses the lattice column correction device 100 of Embodiment 2 of the present invention and may include:

[0055] In step S401, the extension and retraction control of each first hydraulic cylinder 102 causes each side plate 101 to expand outward with the vertical center line of the top plate 109 as the center, so that the lattice column correction device 100 is fitted onto the lattice column 200 through the gaps between the four side plates 101. The extension and retraction control of each first hydraulic cylinder 102 causes each side plate 101 to retract inward with the vertical center line of the top plate 109 as the center. At the same time, the extension and retraction control of each second hydraulic cylinder 103 causes the blind groove 104a of the fastening clamping plate 104 to be assembled on the lower end face of the lacing plate 202 in the corresponding direction of the lattice column 200, and causes the longitudinal through groove 104b of the fastening clamping plate 104 to be assembled on one side plate of the corner plate 201 in the corresponding direction of the lattice column 200, so that the lattice column correction device 100 and the lattice column 200 are clamped and fixedly connected by the fastening clamping plate 104.

[0056] In step S402, the hoisting equipment is connected via a hoisting sling or by setting lifting rings on the upper lifting plate 113 and passing lifting ropes through the lifting rings. The hoisting equipment is then started, and the lattice column correction device 100 and the connected lattice column 200 are simultaneously lifted using the hoisting sling or lifting ropes. The lattice column 200 is then aligned with the reinforcing cage exposed above the pile hole ground and lowered. At this time, the lifting rings can be set at the lifting ring positions 116 on the upper lifting plate 113, that is, at the four corners of the upper lifting plate 113.

[0057] Step S403: Measure the coordinate data of the four corners of the plane where the upper end of the lattice column 200 is located relative to the ground, or measure the coordinate data of the four corners of each side plate 101 relative to the ground. Determine the direction of the vertical deviation and the direction of the horizontal angle deviation of the lattice column 200 by using the coordinate data of the four corners. Correct the verticality of the lattice column 200 by adjusting the length of the flexible adjustment rope on the side where the deviation direction is located. Correct the horizontal angle of the lattice column 200 by rotating the verticality correction component and keeping the horizontal angle correction component stationary through the rotating shaft 110.

[0058] Step S404: Weld the lattice column 200, after verticality and horizontal angle correction, onto the steel cage.

[0059] In step S405, the lattice column correction device 100, the lattice column 200 and its welded steel cage are simultaneously hoisted and lowered into the pile hole. During the lowering process, the verticality of the lattice column 200 and the steel cage in the pile hole is corrected by adjusting the length of each flexible adjustment rope, and the horizontal angle of the lattice column 200 is corrected by rotating the verticality correction component and keeping the horizontal angle correction component stationary through the rotating shaft 110.

[0060] In other words, the main difference between the lattice column correction method provided in Embodiment 2 and the lattice column correction method provided in Embodiment 1 lies in the horizontal angle correction method. Specifically, in Embodiment 2, the hoisting equipment is connected to the upper hanging plate 113 of the horizontal angle correction component. When rotating the verticality correction component, under the action of the rotating shaft 110, the horizontal angle correction component does not rotate or rotates only slightly, thereby ensuring the reliability of the connection between the horizontal angle correction component and the hoisting equipment. This reduces the significant change in the position of the lifting point after the connection, ensuring the stability of the lattice column correction device 100 during the horizontal angle correction process. This minimizes the disturbance of the rotational force on the lattice column correction device 100 and the lattice column 200 when rotating the verticality correction component, thus reducing the amplitude of verticality changes in the lattice column correction device 100 and the lattice column 200, thereby improving the stability of the verticality of the lattice column 200 during the horizontal angle correction process and reducing the number of repeated verticality corrections. The rotation of the verticality correction component can be done manually or with the aid of tools.

[0061] To further improve the installation accuracy of the lattice column 200 and its connected reinforcing cage in the pile hole, the lattice column correction device 100 and method provided in the above embodiments of the present invention can measure the deviation distance between the coordinates of the vertical center line of the lattice column 200 and the coordinates of the center of the pile hole by using an external measuring instrument or a position sensor 105 set on the vertical center line of the upper lifting plate 113 to correct the positioning of the lattice column 200 and the reinforcing cage in the pile hole.

[0062] The lattice column correction device 100 and method provided in the above embodiments of the present invention allow for adjustments to the verticality, horizontal angle, and center positioning of the lattice column 200 by observing the data displayed on the operation panel 115. The operation panel 115 allows input of data such as the vertical centerline coordinates of the pile hole via a keyboard. It also allows input of the allowable error ranges for verticality, horizontal angle, and positioning. For example, a positioning deviation of 50mm and a verticality deviation of 1 / 300L can be set via keyboard input. Here, L represents the length.

[0063] The lattice column correction device 100 and method provided in the above embodiments of the present invention can effectively intervene to increase the accuracy of the positioning of the lattice column 200, ensure the requirements of verticality and horizontal angle, avoid the need to add gusset plates due to deviations in verticality and horizontal angle, improve the welding quality and efficiency of the scissor bracing, and to a certain extent avoid the safety problems caused by the deviation of the lattice column 200, thereby improving the construction quality and safety factor.

[0064] The lattice column correction device 100 and method provided in the above embodiments of the present invention can be operated as follows:

[0065] I. Drilling of engineering piles to form pile holes.

[0066] 2. The reinforcing cage is lowered into the pile hole and protrudes above the ground surface of the pile hole.

[0067] 3. Install a position sensor 105 at each corner of the four side plates 101 and on the upper surface of the vertical center line of the upper hanging plate 113, for a total of 5 position sensors 105.

[0068] IV. Perform steps S401 to S405 as described above. In step S405, during the synchronous hoisting and lowering of the lattice column correction device 100, the lattice column 200, and its welded steel cage into the pile hole, when the mud surface of the lattice column 200 is 50cm below the plane of the pile hole, the coordinates of the vertical center line of the lattice column correction device 100 are fed back by the position sensor 105 on the upper lifting plate 113 as the coordinates of the lattice column 200. The central controller 114 calculates the positioning deviation between the coordinates of the vertical center line of the lattice column 200 and the vertical center line of the pile hole, and applies external force to pull the lattice column correction device 100 laterally to adjust the positioning of the lattice column correction device 100, the lattice column 200, and its welded steel cage in the center of the pile hole. When the mud surface of the lattice column 200 submerged in the pile hole is 10cm from the plane of the pile hole, the positioning deviation of the lattice column correction device 100, the lattice column 200, and its welded steel cage in the center of the pile hole can be readjusted. That is, the positioning accuracy is improved by the initial coarse adjustment and the subsequent fine adjustment. Of course, the positioning adjustment is not limited to two times and can be adjusted appropriately according to the construction situation.

All other embodiments obtained by those skilled in the art based on the described embodiments of this invention are within the scope of protection of this invention. Those skilled in the art can make other modifications and variations to this invention. Therefore, if these modifications and variations of this invention fall within the scope of the claims of this invention, then this invention also intends to include these modifications and variations.
