Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a multi-directional adjustment device and method for positioning steel structures. Background Technology

[0002] The reverse construction method is a construction method that utilizes all or part of the main underground structure as a supporting structure, and constructs the underground structure from top to bottom, alternating with the excavation of the foundation pit. The reverse construction method is increasingly being used in underground building engineering.

[0003] After the inverted floor slab is formed, the vertical structure needs to be constructed, typically using steel or concrete columns. If steel columns are used as the vertical structural columns, the steel column heads need to be embedded during the construction of the inverted floor slab for subsequent connection to the steel columns. During the connection process, due to the influence of the inverted floor slab, large machinery cannot use a one-step hoisting method; the steel columns need to be installed in sections. When installing the intermediate steel structural columns, the intermediate steel structural columns and the lower steel structural columns below need to maintain consistent verticality, and the connection accuracy between the steel column heads and the intermediate steel structural columns also needs to be controlled.

[0004] Currently, in order to ensure the verticality of the intermediate steel structure columns and the lower steel structure columns, it is necessary to pre-install heavy objects so that the line of the heavy objects coincides with the line of the lower steel structure columns. During the process of lowering the intermediate steel structure, the alignment of the lines needs to be performed several times at intervals, which increases the manpower required for installing the steel structure columns and results in low installation efficiency. Summary of the Invention

[0005] To reduce the manpower required for installing steel structure columns and thus improve the efficiency of steel structure column installation, this application provides a multi-directional adjustment device and method for steel structure positioning.

[0006] On the one hand, the multi-directional adjustment device for steel structure positioning provided in this application adopts the following technical solution:

[0007] A multi-directional adjustment device for positioning steel structures includes:

[0008] An adjustable outer frame is set between the upper steel structure column and the lower steel structure column to determine the position of the middle steel structure column. The middle steel structure column can be embedded in the adjustable outer frame. The adjustable outer frame includes multiple fixed mounting rods, with each pair of mounting rods forming a group. The mounting rods in the same group are on the same straight line.

[0009] A telescopic screw, installed between the same group of mounting rods, is used to adjust the distance between the same group of mounting rods;

[0010] An jacking screw is installed on two sets of parallel mounting rods, and the jacking screw is perpendicular to the mounting rods.

[0011] By adopting the above technical solution, the operation does not require preparatory activities. The positions of the upper and lower steel structure columns are fixed first, and then the adjustable frame is fixed. The middle steel structure column to be installed is moved from away from the upper steel structure column to closer to the upper steel structure column. Adjustment is made by using the jacking screw and fastening nut. There is no need to perform several straight alignments at intervals, which reduces the manpower required for installing steel structure columns and improves the efficiency of steel structure column installation.

[0012] Optionally, a fastening nut is also provided on the outside of the mounting rod. The fastening nut cooperates with the jacking screw. When the fastening nut is tightened, the jacking screw can apply pressure to the mounting rod.

[0013] By adopting the above technical solution, the fastening nut can fix the position of the jacking screw, thereby fixing the adjustable outer frame and the central steel structure column. During operation, the jacking screws on both sides need to be tightened separately, and then the fastening nut should be tightened. The unscrewing of the jacking screw will push the central steel structure to the desired position.

[0014] Optionally, the number of fastening nuts and the number of jacking screws correspond, and at least two fastening nuts and two jacking screws are provided.

[0015] By adopting the above technical solution, the fastening nut is responsible for tightening and fixing the position of the jacking screw. Therefore, the number of fastening nuts and jacking screws needs to correspond, with each fastening nut responsible for fixing a pair of jacking screws. Furthermore, at least two fastening nuts and jacking screws are provided, two on each side of the mounting rod, allowing for symmetrical position adjustment.

[0016] Optionally, an angle steel is installed on one side of the mounting rod that is not used for installing the fastening nut and the jacking screw. The angle steel is located at the end of the mounting rod away from the telescopic screw.

[0017] By employing the above technical solution, the angle steel is used to limit the position of the central steel structure column. When the central steel structure column abuts against the angle steel, it proves that the central steel structure column has moved to the appropriate position.

[0018] Optionally, ear plates are provided between the middle steel structure column and the upper steel structure column. The ear plates are respectively provided on the sides of the middle steel structure column and the upper steel structure column, and ear plates are provided on both sides of the middle steel structure column and the upper steel structure column.

[0019] By adopting the above technical solution, the ear plates are designed to measure the adjustable outer frame before the central steel structure column is finally fixed, and then fine-tune the position of the adjustable outer frame by tightening nuts and jacking screws, thereby indirectly adjusting the position of the central steel structure column. During operation, a chain hoist is used to lift the steel column through the ear plates on both sides for subsequent measurements.

[0020] Optionally, a support rod is provided at the end of the mounting rod away from the mounting of the fastening nut and the jacking screw. Multiple support rods are provided, with two support rods forming a group, and each group of support rods is symmetrically arranged about the mounting rod.

[0021] By adopting the above technical solution, the support rods are positioned appropriately within the adjustable outer frame, thereby allowing for further refinement of the location of the central steel structure columns. Furthermore, multiple support rods are provided, resulting in more stable support for the adjustable outer frame. The symmetrical arrangement of two support rods ensures that each mounting rod of the adjustable outer frame is parallel, guaranteeing the accuracy of the adjustment.

[0022] On the other hand, this application provides an installation method for a multi-directional adjustment device for steel structure positioning.

[0023] Optional steps include:

[0024] Preparation: The lower and upper steel structure columns have been positioned and temporarily fixed; the adjustable outer frame is passed through the upper and lower steel structure columns and tightly connected to the upper and lower steel structure columns respectively;

[0025] Positioning Completed: Using lifting equipment, the middle steel structure column to be installed is moved from the direction away from the upper steel structure column to the direction closer to the upper steel structure column until the middle steel structure column is pushed to abut against the angle steel and cannot be pushed further.

[0026] Fixed position: After completion, weld the two side ear plates to the central steel structure column. After welding, lift the steel column by passing a chain hoist through the two side ear plates. Support the column at a suitable external position and clarify the corresponding position of the steel column in the front and rear directions.

[0027] Position adjustment: Adjust simultaneously based on measurement results. If the steel column is found to be twisted, the jacking screw can be adjusted individually to correct the twist.

[0028] Installation complete: After adjustment, weld the ear plate to the upper steel structure column to complete the steel column positioning and temporary fixing installation.

[0029] By adopting the above technical solution, the operation requires preparatory activities first, fixing the positions of the upper and lower steel structure columns, then fixing the adjustable frame, moving the middle steel structure column to be installed from away from the upper steel structure column to closer to the upper steel structure column, and then measuring and further accurately positioning it through the ear plate. After adjustment, the installation is complete.

[0030] Optionally, the adjustable outer frame is tightly connected to the upper steel structure column and the lower steel structure column respectively, including the steps of: adjusting the telescopic screw to make the adjustable outer frame tightly hug the lower steel structure column and the upper steel structure column respectively.

[0031] By adopting the above technical solution, when it is necessary to connect the adjustable outer frame to the upper and lower steel structure columns respectively, the middle steel structure column can be indirectly installed using the adjustable outer frame. During operation, the adjustable outer frame is moved below the upper steel structure column, and the telescopic screw is screwed on, allowing the telescopic outer frame to abut against both the upper and lower steel structure columns respectively.

[0032] Optionally, support rods are installed at suitable external locations, and the corresponding positions of the steel columns in the front and rear directions are determined. This includes the following steps: connecting the support rods to the installation rods, adjusting the angle of the support rods to support the adjustable outer frame, taking measurements, and determining whether the installation is qualified based on the measurement results.

[0033] By adopting the above technical solution, the support rods are installed at suitable positions on the adjustable outer frame, thereby further refining the position of the central steel structure column. During operation, the support rods are connected to the mounting rods, which alters the angle of the adjustable outer frame. Measurements and subsequent fine-tuning ensure the correct installation position of the central steel structure column.

[0034] Optionally, adjustments can be made simultaneously based on the measurement results, including the following steps: the jacking screws on both sides are used to push the central steel structure column to the designated position by the stroke of the jacking screws and fix it with the fastening nuts at the rear.

[0035] By adopting the above technical solution, it is necessary to screw the jacking screws on both sides separately and then fix them with fastening nuts. The jacking screws can push the central steel structure to the required position, making the installation position of the central steel structure column more accurate. Multiple jacking screws can make fine adjustments to the central steel structure column at different positions, thereby fixing the position of the jacking screws.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] By incorporating an adjustable outer frame, mounting rods, telescopic screws, jacking screws, and fastening nuts, the installation process requires preparatory work to fix the positions of the upper and lower steel structure columns. Then, the adjustable frame is secured, and the middle steel structure column to be installed is moved from the column furthest from the upper column towards the column closest to it. Adjustment is achieved using the jacking screws and fastening nuts. This eliminates the need for multiple straight-line alignments, reducing the manpower required for steel structure column installation and thus improving installation efficiency.

[0038] By setting up ear plates, the operation requires preparatory activities first, fixing the positions of the upper and lower steel structure columns, and then fixing the adjustable frame. The middle steel structure column to be installed is then moved from away from the upper steel structure column to closer to the upper steel structure column. Adjustment is made by using the jacking screw and fastening nut. There is no need to perform several straight alignments at intervals, which reduces the manpower required for installing steel structure columns and improves the efficiency of steel structure column installation.

[0039] By incorporating support rods positioned appropriately within the adjustable outer frame, the location of the central steel structure columns can be further refined. Multiple support rods provide greater stability to the adjustable outer frame, and their symmetrical arrangement ensures that each mounting rod of the adjustable outer frame is parallel, guaranteeing accurate adjustments.

[0045] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0046] This application discloses a multi-directional adjustment device for positioning steel structures.

[0047] Reference Figure 1 and Figure 2 A multi-directional adjustment device for positioning a steel structure includes an adjustable outer frame 1 set between an upper steel structure column 8 and a lower steel structure column 10, a telescopic screw 2 set inside the adjustable outer frame 1, and a jacking screw 3 installed on two sets of parallel mounting rods 11.

[0048] The adjustable outer frame 1 is used to determine the position of the central steel structure column 9. The central steel structure column 9 can be embedded in the adjustable outer frame 1. The adjustable outer frame 1 includes multiple mounting rods 11 fixedly connected to each other. Every two mounting rods 11 form a group, and the mounting rods 11 in the same group are on the same straight line. Telescopic screws 2 are installed between the mounting rods 11 in the same group to adjust the distance between the mounting rods 11 in the same group; the jacking screw 3 is perpendicular to the mounting rods 11.

[0049] During operation, preparatory activities are required first. The positions of the upper steel structure column 8 and the lower steel structure column 10 are fixed. Then, the adjustable frame is fixed. The middle steel structure column 9 to be installed is moved from away from the upper steel structure column 8 to closer to the upper steel structure column 8. Adjustment is made by using the jacking screw 3 and the fastening nut 4. There is no need to perform several straight alignments at intervals, which reduces the manpower required for installing steel structure columns and improves the efficiency of steel structure column installation.

[0050] Reference Figure 1 and Figure 2 A fastening nut 4 is also provided on the outside of the mounting rod 11. The fastening nut 4 cooperates with the jacking screw 3. When the fastening nut 4 is tightened, the jacking screw 3 can apply pressure to the mounting rod 11. The number of fastening nuts 4 and jacking screws 3 corresponds, and the number of fastening nuts 4 and jacking screws 3 is at least two.

[0051] The fastening nut 4 secures the position of the jacking screw 3, thereby fixing the adjustable outer frame 1 and the central steel structure column 9 together. During operation, the jacking screws 3 on both sides are tightened separately, and then the fastening nut 4 is tightened. The unscrewing of the jacking screw 3 pushes the central steel structure to the desired position.

[0052] The fastening nut 4 is responsible for tightening and fixing the position of the jacking screw 3, so the number of fastening nuts 4 and jacking screws 3 must correspond, with each fastening nut 4 responsible for fixing a pair of jacking screws 3. Furthermore, at least two fastening nuts 4 and jacking screws 3 are provided, two on each side of the mounting rod 11, allowing for symmetrical position adjustment.

[0053] An angle steel 5 is installed on one side of the mounting rod 11, which is not used for installing the fastening nut 4 and the jacking screw 3. The angle steel 5 is located at the end of the mounting rod 11 away from the telescopic screw 2. The angle steel 5 is used to limit the position of the central steel structure column 9. When the central steel structure column 9 abuts against the angle steel 5, it proves that the central steel structure column 9 has moved to the appropriate position.

[0054] Reference Figure 1 and Figure 2 A lug plate 6 is installed between the middle steel structure column 9 and the upper steel structure column 8. The lug plate 6 is located on the sides of both the middle steel structure column 9 and the upper steel structure column 8, and lug plates 6 are also installed on both sides of the middle steel structure column 9 and the upper steel structure column 8. The lug plate 6 is installed to measure the adjustable outer frame 1 before finally fixing the middle steel structure column 9, and then fine-tune the position of the adjustable outer frame 1 by tightening the fastening nut 4 and the jacking screw 3, thereby indirectly adjusting the position of the middle steel structure column. During operation, the steel column is lifted by passing a chain hoist through the lug plates 6 on both sides, so as to perform subsequent measurements.

[0055] A support rod 7 is provided at the end of the mounting rod 11 away from the mounting fastening nut 4 and the jacking screw 3. Multiple support rods 7 are provided, with two support rods 7 forming a group, and each group of support rods 7 is symmetrically arranged about the mounting rod 11. The support rods 7 are positioned appropriately on the adjustable outer frame 1, thereby allowing for further refinement of the position of the central steel structure column 9. Furthermore, the multiple support rods 7 provide more stable support for the adjustable outer frame 1, and the symmetrical arrangement of two support rods 7 ensures that each mounting rod 11 of the adjustable outer frame 1 is parallel, thus guaranteeing the accuracy of adjustment.

[0056] The implementation principle of the multi-directional adjustment device for steel structure positioning in this application embodiment is as follows: During operation, preparatory activities are required first. The positions of the upper steel structure column 8 and the lower steel structure column 10 are fixed. Then, the adjustable frame is fixed. The middle steel structure column 9 to be installed is moved from away from the upper steel structure column 8 to closer to the upper steel structure column 8. Then, the ear plate 6 is used for measurement and further precise positioning. After adjustment, the installation is completed.

[0057] Reference Figure 3 and Figure 4 On the other hand, this application provides an installation method for a multi-directional adjustment device for steel structure positioning.

[0058] Including the following steps:

[0060] S11. By adjusting the telescopic screw 2, the adjustable outer frame 1 is made to hug the lower steel structure column 10 and the upper steel structure column 8 respectively.

[0061] When it is necessary to connect the adjustable outer frame 1 to the upper steel structure column 8 and the lower steel structure column 10 respectively, so that the middle steel structure column 9 can be indirectly installed using the adjustable outer frame 1, the operation is as follows: move the adjustable outer frame 1 below the upper steel structure column 8, and screw the telescopic screw 2 so that the telescopic outer frame can abut against the upper steel structure column 8 and the lower steel structure column 10 respectively.

[0062] S2. Complete positioning: Use lifting equipment to move the middle steel structure column 9 to be installed in a direction from away from the upper steel structure column 8 to close to the upper steel structure column 8, until the middle steel structure column 9 is pushed to abut against the angle steel 5 and cannot be pushed further.

[0063] S3. Fixing the position: After completion, weld the two side ear plates 6 to the central steel structure column 9. After welding, lift the steel column by passing a chain hoist through the two side ear plates 6.

During operation, the support rod 7 is connected to the mounting rod 11, thereby changing the angle of the adjustable outer frame 1. Measurement and subsequent fine-tuning ensure that the installation position of the central steel structure column 9 is qualified.

[0066] S4. Adjust position: Adjust simultaneously according to the measurement results. If the steel column is found to be twisted, the jacking screw 3 can be adjusted individually to correct the twist.

[0067] S41. The jacking screws 3 on both sides push the central steel structure column 9 to the designated position by the stroke of the jacking screws 3 and fix it with the fastening nuts 4 at the rear.

[0068] The two jacking screws 3 on both sides need to be screwed on separately, and then the fastening nut 4 is fixed in place. The jacking screws 3 can be screwed on to push the central steel structure to the required position, so that the installation position of the central steel structure column 9 is more accurate. Multiple jacking screws 3 can be used to fine-tune the central steel structure column 9 at different positions, thereby fixing the position of the jacking screws 3.

[0069] S5. Installation complete: After the adjustment is completed, weld the ear plate 6 to the upper steel structure column 8 to complete the steel column positioning and temporary fixing installation.

[0070] During operation, preparatory activities are required first. The positions of the upper steel structure column 8 and the lower steel structure column 10 are fixed.
