Description

Technical Field

[0001] This utility model belongs to the field of steel structure installation and construction technology, specifically relating to a verticality correction device for high-rise box-type column installation. Background Technology

[0002] Steel structures possess advantages such as superior mechanical properties, high degree of industrialization, and environmentally friendly materials. These advantages are particularly prominent in the construction of high-rise buildings, large-scale spatial facilities, commercial facilities, factories and warehouses, and complete sets of equipment structures. Currently, the application and development of steel structures in the construction field has entered a golden age. Thanks to the strong promotion of prefabricated steel structure policies in my country, the development space for high-rise and super high-rise steel structure buildings in my country is also expanding rapidly.

[0003] In high-rise and super high-rise buildings, steel columns are mostly box-shaped columns, typically fabricated and installed in sections. However, due to factors such as factory processing deviations, installation sequence, and inadequate welding, the verticality of upper and lower steel columns is prone to deviation. If the lower steel columns are not properly aligned before installing steel beams, the cumulative deviation of subsequent steel columns will increase exponentially, making column alignment significantly more difficult and causing serious construction quality and safety hazards. Therefore, controlling the verticality of steel columns during the installation of high-rise and super high-rise steel structures has always been a challenging issue in the industry and a key factor affecting the overall installation quality. This requires us to measure each steel column section during installation and connection, and to promptly correct any deviations exceeding the specified values.

[0004] Traditional steel column verticality correction involves welding temporary support plates above and below the inclined side of the steel column as load-bearing fulcrums, loosening the clamping bolts, and placing a jack between the upper and lower support plates, using guy ropes for correction. This method has significant safety hazards and is unreasonable. After correction, the temporary support plates need to be removed, requiring grinding and repainting of the removed areas, which is time-consuming, labor-intensive, inefficient, and affects the construction schedule. While portable plug-in correction devices have appeared on some sites, these are not fixed connections, and force applied during construction may cause the jack to dislodge, posing a safety hazard. Therefore, a safe, easy-to-operate, and convenient device is needed to meet the installation and correction requirements of high-rise box-type columns. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a verticality correction device for the installation of high-rise box-type columns. The purpose of this utility model is to quickly adjust the angle of the steel column by fine adjustment while ensuring safe construction, control the verticality of the steel column, solve the problem of verticality deviation in the installation of high-rise and super high-rise box-type columns, and achieve the purpose of quickly and safely correcting the verticality of steel columns at high altitudes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A verticality correction device for a high-rise box-type column includes a lower column lug plate located on the side of the lower box-type column and an upper column lug plate located on the side of the upper box-type column, which is installed vertically to the lower box-type column. It also includes double clamping plates and a correction device. The double clamping plates are inserted into both sides of the upper and lower column lug plates during use. The correction device includes an upper limit plate, a lower limit plate, and a closing device. During use, one end of the upper limit plate is connected to the upper end of the double clamping plates and the upper column lug plate, and one end of the lower limit plate is connected to the lower end of the double clamping plates and the lower column lug plate, keeping the upper and lower limit plates horizontally parallel. The closing device is located between the upper and lower limit plates, with both ends connected to the upper and lower limit plates respectively. The closing device achieves fine-tuning of the angle of the upper box-type column by pushing against the upper and lower limit plates.

[0008] The upper limit plate and the lower limit plate are both L-shaped structures. One side of the upper limit plate is connected to the upper column ear plate and the double clamping plate by two or more pins or bolts, and the other side of the upper limit plate is connected to the closing device by pins or bolts. One side of the lower limit plate is connected to the lower column ear plate and the double clamping plate by two or more pins or bolts, and the other side of the lower limit plate is connected to the closing device by pins or bolts.

[0009] Furthermore, the upper limit plate of the L-shaped plate has two or more upper limit bolt holes evenly distributed on one side for connecting with the upper column ear plate and the double clamping plate. The upper limit bolt holes are connected to the corresponding holes on the upper column ear plate and the double clamping plate by pins or bolts. The lower limit plate of the L-shaped plate has two or more lower limit bolt holes evenly distributed on one side for connecting with the lower column ear plate and the double clamping plate. The lower limit bolt holes are connected to the corresponding holes on the lower column ear plate and the double clamping plate by pins or bolts.

[0010] Furthermore, the upper limit plate has an upper connecting round hole at one end connected to the closing device, and the lower limit plate has a lower connecting waist-shaped hole at one end connected to the closing device.

[0011] Furthermore, both the upper and lower ends of the closing device are fixedly connected to upright plates, and the upright plates are provided with upright plate connection holes; the upright plate connection holes on the upright plates at the upper end of the closing device are connected to the upper connecting round holes on the upper limit plate by pins or bolts.

[0012] The vertical plate connection hole on the vertical plate at the lower end of the closing device is connected to the lower connecting waist-shaped hole on the lower limit plate by a pin or bolt.

[0024] Please see Figure 1-4 The embodiments of this utility model are described in detail below.

[0025] Example: This example, while ensuring the safety of operators during the high-rise steel column straightening process, fully considers the safety of operators and prevents accidents during the straightening process. It designs a movable straightening device that can be freely installed and disassembled according to actual work conditions, specifically for the actual installation of high-rise buildings. This helps installers safely and quickly straighten steel column verticality deviations, avoiding engineering quality and safety risks caused by verticality deviations. The specific structure is as follows... Figure 1 , 2 As shown:

[0026] A verticality correction device for high-rise box-type columns is installed, including a lower column ear plate 4 welded to the side of the lower box-type column 2, and an upper column ear plate 3 welded to the side of the upper box-type column 1, which is installed vertically and vertically to the lower box-type column 2. It also includes a double clamp plate 5 and a straightening device. The double clamp plate 5 is inserted into both sides of the upper column ear plate 3 and the lower column ear plate 4 during use. The straightening device includes an upper limit plate 6, a lower limit plate 7 and a closing device 9. During use, one end of the upper limit plate 6 is connected to the upper end of the double clamp plate 5 and the upper column ear plate 3, and one end of the lower limit plate 7 is connected to the lower end of the double clamp plate 5 and the lower column ear plate 4. The upper limit plate 6 and the lower limit plate 7 are kept horizontally parallel. The closing device 9 is located between the upper limit plate 6 and the lower limit plate 7. The two ends of the closing device 9 are connected to the upper limit plate 6 and the lower limit plate 7 respectively. The closing device 9 achieves fine adjustment of the angle of the upper box column 1 by pushing the upper limit plate 6 and the lower limit plate 7.

[0027] In this embodiment, the entire connecting device adopts an assembly design for easy installation and disassembly. During steel column installation, after hoisting the upper box-type column 1 into place, ensure its bottom centerline aligns with the top control point of the lower box-type column 2 on all four sides. Smoothly insert the double clamping plates 5 into the ear plates on both sides of the upper and lower box-type columns. Install the upper and lower limiting plates sequentially in the corresponding holes of the double clamping plates 5, and then tighten them with pins or bolts. Use a measuring ruler to check for any deviation in the verticality of the upper box-type column 1. If a deviation in the verticality of the upper box-type column 1 is found, install two sets of closing devices 9 between the corresponding two sets of upper and lower limiting plates on the side of the deviation. Rotate the ratchet assembly of the closing device 9 to raise the sleeve. Adjust the angle of the steel column by pushing with the closing device 9 until the deviation on that side meets the installation accuracy requirements. This box-type column installation and correction device uses screw connections, is reusable, and is very convenient to install and disassemble. It is safe and reliable to use and effectively reduces costs.

[0028] In one specific embodiment, both the upper limit plate 6 and the lower limit plate 7 are L-shaped structures; one side of the upper limit plate 6 is connected to the upper column ear plate 3 and the double clamping plate 5 by two or more pins or bolts, and the other side of the upper limit plate 6 is connected to the closing device 9 by pins or bolts; one side of the lower limit plate 7 is connected to the lower column ear plate 4 and the double clamping plate 5 by two or more pins or bolts, and the other side of the lower limit plate 7 is connected to the closing device 9 by pins or bolts.

[0029] In this embodiment, the upper limit plate 6 of the L-shape has three evenly distributed upper limit bolt holes 6-1 with a diameter of 22mm on one side for connecting with the upper pillar ear plate 3 and the double clamping plate 5. The upper limit bolt holes 6-1 are connected to the corresponding holes on the upper pillar ear plate 3 and the double clamping plate 5 by pins or bolts. The lower limit plate 7 of the L-shape has three evenly distributed lower limit bolt holes 7-1 with a diameter of 22mm on one side for connecting with the lower pillar ear plate 4 and the double clamping plate 5. The lower limit bolt holes 7-1 are connected to the corresponding holes on the lower pillar ear plate 4 and the double clamping plate 5 by pins or bolts.

[0030] The upper limit plate 6 has an upper connecting round hole 6-2 with a diameter of 32mm at one end connected to the closing device 9, and the lower limit plate 7 has a lower connecting waist-shaped hole 7-2 with a diameter of 32mm*100mm at one end connected to the closing device 9, which facilitates installation and adjustment.

[0031] In the above structure, during installation, the two right-angled interlocking upper and lower limit plates face inwards, and the closing device is placed between them, connected to the upper and lower limit plates with pins. The upper and lower limit plates are fixed to the upper and lower box-shaped columns respectively by pins or bolts, ensuring the horizontality of the upper and lower limit plates, and also ensuring the flatness and horizontality of the straightening device during operation.

[0032] In one specific implementation: See Figure 3 and4 As shown, the upper and lower ends of the closing device 9 are fixedly connected with upright plates 8. In this embodiment, each end has two upright plates, which are placed in the middle with a gap of 30mm between them. They are welded to the top plate of the original chain link of the closing device.

[0033] The upright plate 8 is provided with an upright plate connecting hole 8-1; the upright plate connecting hole 8-1 on the upper end of the upright plate 8 of the closing device 9 is connected to the upper connecting round hole 6-2 on the upper limit plate 6 by a pin or bolt; the upright plate connecting hole 8-1 on the lower end of the upright plate 8 of the closing device 9 is connected to the lower connecting waist-shaped hole 7-2 on the lower limit plate 7 by a pin or bolt.

[0034] In this embodiment, considering that the chain link of the traditional closing device cannot be fixed to the lower limit plate, the chain link is modified into a perforated vertical plate, which is welded to the lower chain position of the closing device for easy installation. In this way, both the upper and lower parts of the closing device are securely connected to the upper and lower limit plates by pins or bolts, preventing the closing device from slipping under force during operation and ensuring that the operator can work in a safe condition.

[0035] Construction process of this device:

[0036] 1) Before hoisting, insert the double clamping plate 5 and the upper limit plate 6 into the corresponding upper column ear plate 3 of the upper box column 1, and thread the connecting pins or bolts. After hoisting into place, ensure that the center line of the bottom of the upper box column 1 aligns with the center line of the top of the lower box column 2 on all four sides. Then, thread the double clamping plate 5 and the lower limit plate 7 corresponding to the lower column ear plate 4 on the lower box column 2 with pins or bolts, and promptly install guy ropes to initially fix the steel column. At this time, tighten the ear plates between the upper and lower box columns with bolts to prevent loosening. Use a measuring ruler to check whether there are any deviations in the verticality and angle of the upper box column.

[0037] 2) When there are deviations in the verticality and angle of the upper box column 1, two sets of closing devices 9 shall be installed in the direction of the verticality deviation of the box column. The closing devices 9 shall be installed between the upper and lower limit plates and connected to the upper and lower supports with pins or bolts.

[0038] 3) The next step of correction work can only be carried out after the upper and lower limit plates and the closing device are firmly fixed to prevent accidents during use. When using the two sets of closing devices, the lifting speed should be kept synchronized.

[0039] 4) By rotating the ratchet assembly of the closing device, the lifting sleeve is raised. Through the pushing action of the closing device, the angle of the upper box column is finely adjusted until the deviation of the side column meets the installation accuracy requirements.

[0040] 5) After adjustment, remove the correction device and move it to other steel columns with deviations. Repeat the above operation method until all directions of this steel column meet the installation requirements before proceeding with subsequent construction.

[0041] This device, while ensuring safe construction, enables rapid adjustment of the steel column angle to control the verticality of the steel column, solving the problem of verticality deviation in the installation of box-type columns in high-rise and super high-rise buildings, and playing a role in quickly and safely correcting the verticality of steel columns at high altitudes.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
