Description

Technical Field

[0001] The invention relates to the technical field of steel column verticality correction, and in particular to a device for quickly adjusting the verticality of a steel structure and a construction process thereof. Background Art

[0002] Vertical adjustment of steel structures is an important construction link, especially in high-rise buildings, bridges and other large structures. In steel structure construction, the device for adjusting verticality is mainly used on key components that need to ensure verticality, among which steel columns are a particularly important part; as an important part of the load-bearing structure, the verticality of the steel column directly affects the safety and stability of the entire building. Therefore, ensuring the verticality of the steel column is very critical.

[0003] Steel columns mainly include I-beams, channel steels, angle steels, round tube columns, square tube columns, box columns, T-shaped steel columns and combined columns, etc. Existing steel structure verticality adjustment devices are relatively cumbersome and have a relatively narrow scope. For example, the Chinese invention patent with the document number CN112282394A, named as a steel column verticality efficient adjustment device, requires manual connection of two adjacent steel columns, and then installation of a jack to adjust the verticality. The device needs to detect the verticality first, and then start the jack, and the two processes are separated, so the adjustment is relatively cumbersome and the efficiency is low. Another example is the Chinese invention patent with the document number CN114150882B, named as a verticality correction device for steel columns of steel structure buildings, which has a relatively complex overall structure and many operation processes, so the adjustment efficiency is low. Summary of the invention

[0009] A second oil cylinder capable of driving the slide bar to extend and retract along the slide groove is arranged outside the movable rod; the second oil cylinder is detachably fixedly connected to the slide bar.

[0011] Furthermore, a motor slot is formed on the inward side of the base, and a protective cover is hinged at the outlet of the motor slot; a motor is fixedly installed inside the motor slot, and a first driving shaft is connected to the output end of the motor. The first driving shaft passes through the base upward, and a turntable is connected to the top of the first driving shaft, and a fixed seat is fixedly installed on the upper surface of the turntable.

[0012] Furthermore, the transmission component includes a connecting rod connected to the top of the slide rod, and a movable ball is arranged on the top of the connecting rod; a ball seat is arranged on the side of the abutment plate close to the slide rod, and the ball seat has a spherical groove; the movable ball is confined in the spherical groove and is rotatably connected thereto.

[0013] Furthermore, a supporting structure is provided between the bottom of the abutment plate and the telescopic rod; the supporting structure comprises an adjusting rod which is rotatably connected to the bottom of the abutment plate and can be telescopic.

[0014] Furthermore, the sliding rod has several positioning screw holes equidistantly arranged along its length direction, and a fixing plate is fixedly connected to both ends of the second oil cylinder. The fixing plate at the front end of the second oil cylinder is fixedly connected to the movable rod, and the fixing plate at the end of the second oil cylinder is also provided with positioning screw holes; the screw rod is threadedly connected to the positioning screw holes on the fixing plate and the positioning screw holes on the sliding rod at the same time.

[0015] Furthermore, a level is provided on the side of the abutment plate; and a counterweight is connected to the bottom of the abutment plate.

[0017] A construction process of a device for quickly adjusting the verticality of a steel structure comprises the following steps:

[0018] Step 1: Determine the width of the abutment plate according to the shape and size of the steel column, install the movable ball into the ball seat, then connect the connecting rod with the movable ball, then insert and fix the connecting rod to the top of the sliding rod, then weld the ball seat to the abutment plate, then connect the sliding rod to the spring, and then fix the spring to the bottom of the slide groove;

[0021] Step 4: Start the first oil cylinder to extend the movable rod so that the abutment plate is close to the upper steel column. When the lower part of the abutment plate contacts the outer side of the upper steel column first, stop the first oil cylinder corresponding to the abutment plate; when the upper part of the abutment plate contacts the outer side of the upper steel column first, continue to start the first oil cylinder to extend the movable rod until the side surface of the abutment plate completely contacts the side surface of the upper steel column after tilting;

The operation is simple and fast, which improves the efficiency of the verticality detection and adjustment of the steel column, and the detection and adjustment are more accurate.

[0025] 2. By setting a device for quickly adjusting the verticality of the steel structure around the steel column, the width of each abutment plate is much smaller than the width of one side of the steel column. For steel columns of different shapes, the abutment plate can be tightly attached to different parts of the outer side of the corresponding steel column, which greatly improves the application scope of this solution.

[0026] 3. By setting up a supporting structure, after determining the abutment position between the abutment plate and the steel column, the position of the abutment plate is relatively fixed and will not shake at will, affecting the verticality detection; when the verticality of the steel column needs to be adjusted, the abutment plate is provided with supporting force so that the abutment plate pushes the steel column to restore verticality; by setting up driving components and servos, the angle of the telescopic rod can be adjusted at will, making it more convenient to use; by setting up a connecting plate, multiple bases are connected together around the steel column.

The sleeve rod and the limit seat 36 are both made of magnetic materials, and a magnet 37 is arranged in the limit seat 36; the magnet 37 is arranged corresponding to the sleeve rod and abuts against the sleeve rod, and the magnet 37 attracts the sleeve rod to fix it; because the telescopic rod 10 will not rotate at the same inclination angle for different adjustment positions, the sleeve rod corresponds to the height of the telescopic rod. Therefore, the sleeve rod is fixed by a detachable limit seat 36 and a magnet 37 that is convenient for adjusting the position at will, which is easy to operate and can adapt to various situations.

[0049] By setting up a supporting structure, after the abutment position between the abutment plate and the steel column is determined, the position of the abutment plate is relatively fixed and will not shake at will, affecting the verticality detection; when the verticality of the steel column needs to be adjusted, supporting force is provided for the abutment plate so that the abutment plate pushes the steel column to restore verticality.

[0050] The slide bar 19 has a number of positioning screw holes 22 equidistantly provided along its length direction. A fixing plate 21 is fixedly connected to both ends of the second oil cylinder 20. The fixing plate 21 at the head end of the second oil cylinder 20 is fixedly connected to the movable rod, and the fixing plate 21 at the end of the second oil cylinder 20 is also provided with a positioning screw hole 22; the screw rod 23 is threadedly connected to the positioning screw hole 22 on the fixing plate 21 and the positioning screw hole 22 on the slide bar 19 at the same time, so that the end of the second oil cylinder 20 is connected to the slide bar 19 when the steel column is pushed to make it vertical, and when the abutment plate 25 begins to approach the steel column, the second oil cylinder 20 is not connected to the slide bar 19.

[0051] A spirit level 31 is provided on the side of the abutment plate 25; a counterweight block 32 is connected to the bottom of the abutment plate 25 to facilitate its natural verticality; the spirit level 31 has a simple structure, and is small in mass and volume, and is convenient for installation on the abutment plate 25 to assist in detecting verticality and prevent errors; the spirit level 31 is used to place one side of the spirit level 31 close to the surface to be measured so that the spirit level 31 is in a side position. If the bubble is in the middle position, it indicates that the spirit level 31 is in a horizontal state at this time, but since it is placed on its side, this means that the surface it is against is actually vertical.

[0052] When there are two or more bases 1, limiting grooves 11 are opened on opposite sides of adjacent bases 1, and both ends of the connecting plate 12 are inserted into the limiting grooves 11 of the adjacent bases 1. The limiting grooves 11 of the adjacent bases 1 are connected through the connecting plate 12, and the connecting plate 12 is fixedly connected to the base 1 through positioning bolts 13, and the connecting plate 12 is arc-shaped.

[0053] By arranging a device for quickly adjusting the verticality of the steel structure around the steel column, the width of each abutment plate is much smaller than the width of one side of the steel column. For steel columns of different shapes, the abutment plate can be made to fit tightly against different parts of the outer side of the corresponding steel column, which greatly improves the application scope of the present solution; by arranging driving components and servos, the angle of the telescopic rod can be adjusted at will, which is more convenient to use; by arranging connecting plates, multiple bases are connected together around the steel column. The modular design facilitates disassembly and installation, and improves stability during connection.

[0054] A construction process of a device for quickly adjusting the verticality of a steel structure comprises the following steps:

[0055] Step 1: Determine the width of the abutment plate 25 according to the shape and size of the steel column, install the movable ball 28 into the ball seat 26, then connect the connecting rod 24 with the movable ball 28, then insert and fix the connecting rod 24 on the top of the slide bar 19, then weld the ball seat 26 to the abutment plate 25, then connect the slide bar 19 to the spring 18, and then fix the spring 18 to the bottom of the slide groove 17; each component of this scheme can be prefabricated and can be disassembled and reused;

[0056] Step 2: Determine the number of abutment plates 25 required. When the number is two or more, the bases 1 are arranged equidistantly around the steel column. After the bases 1 are placed, the adjacent bases 1 are connected by connecting plates 12. The size of the connecting plates 12 is determined according to the curvature between the adjacent bases 1. Determine the position of the abutment plate 25 to fit the steel column, then start the motor 4 to rotate the turntable 6 and start the steering gear 701 to adjust the position of the telescopic rod 10, so that the abutment plate 25 can directly contact the preset corresponding position of the steel column after the telescopic rod 10 is extended.

[0057] Step 3: Install the support component and ensure that the abutment plate 25 is in a vertical state by using the level 31, and then record the scale corresponding to the bottom of the slide bar 19 as the initial scale; specifically: according to the level 31, twist the sleeve rod so that one end of it is inserted into the limit seat 36 and abuts against the magnet 37; then install the counterweight 32 at the bottom of the abutment plate 25, and install the level 31 on the side of the abutment plate 25;

[0058] Step 4: Start the first oil cylinder 14 to extend the movable rod so that the contact plate 25 is close to the upper steel column 16. When the lower part of the contact plate 25 contacts the outer side of the upper steel column 16 first, stop the first oil cylinder 14 corresponding to the contact plate 25; when the upper part of the contact plate 25 contacts the outer side of the upper steel column 16 first, continue to start the first oil cylinder 14 to extend the movable rod until the side surface of the contact plate 25 completely contacts the side surface of the upper steel column 16 after the inclination; in this process, since the upper steel column 16 tilts to this side, The movable rod continues to be extended, and the movable rod drives the slide bar 19 to move toward the steel column. However, due to the resistance of the steel column, the steel column will press down the upper part of the abutment plate 25 when the movable rod is extended, and the abutment plate 25 presses down the movable ball 28 through the ball seat 26, and the movable ball 28 presses down the slide bar 19 through the connecting rod 24. Since the movable ball 28 is placed in the spherical groove 27 and can rotate arbitrarily, there will be no movement interference between the abutment plate 25 and the slide bar 19. In this process, the slide bar 19 falls in the slide groove 17 to compress the spring 18;

[0059] Step 5: Start the second oil cylinder 20 to push the slide bar 19, so that the slide bar 19 moves to the initial scale, complete the adjustment, and finally place a cushion block to permanently support the upper steel column 16; specifically: connect the fixed plate 21 to the slide bar 19 through the screw 23 and the positioning screw hole 22; start the second oil cylinder 20 to push the slide bar 19 to extend it, and the slide bar 19 pushes the abutment plate 25 through the movable ball 28 and the ball seat 26 to drive the upper steel column 16 to be adjusted to vertical. At the same time, observe whether the corresponding abutment plate 25 on the other side is completely in contact with the side of the steel column, and finally place a cushion block in the gap between the upper steel column 16 and the lower steel column 15, so as to complete the adjustment of the verticality of the steel column.

[0060] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.

A construction process using a device for quickly adjusting the verticality of a steel structure according to claims 1-8, characterized in that: The following steps are involved: Step 1: Determine the width of the abutment plate (25) according to the shape and size of the steel column, install the movable ball (28) into the ball seat (26), then connect the connecting rod (24) with the movable ball (28), then insert and fix the connecting rod (24) on the top of the sliding rod (19), then weld the ball seat (26) to the abutment plate (25), then connect the sliding rod (19) to the spring (18), and then fix the spring (18) to the bottom of the slide groove (17); Step 2: Determine the number of abutment plates (25) required. When the number is two or more, the base (1) is arranged equidistantly around the steel column; After the bases (1) are placed, adjacent bases (1) are connected by connecting plates (12), and the size of the connecting plates (12) is determined according to the curvature between the adjacent bases (1); Step 3: Install the support component and use a level (31) to ensure that the abutment plate (25) is in a vertical state, and then record the scale corresponding to the bottom of the slide rod (19) as the initial scale; Step 4: Start the first oil cylinder (14) to extend the movable rod so that the contact plate (25) is close to the upper steel column (16). When the lower part of the contact plate (25) first contacts the outer side of the upper steel column (16), stop the first oil cylinder (14) corresponding to the contact plate (25); when the upper part of the contact plate (25) first contacts the outer side of the upper steel column (16), continue to start the first oil cylinder (14) to extend the movable rod until the side surface of the contact plate (25) completely contacts the side surface of the upper steel column (16) after tilting; Step 5: Start the second oil cylinder (20) to push the slide bar (19) so that the slide bar (19) moves to the initial scale to complete the adjustment, and finally place a pad to permanently support the upper steel column (16).
