Description

Technical Field

[0001] The present invention belongs to the technical field of steel column installation of steel structure workshops, and in particular relates to an automatic deviation correction device and a construction method suitable for installing steel structure columns of different shapes. Background Art

[0002] Steel structural columns are often large and heavy. Large steel columns can weigh tens or even hundreds of tons and can be quite large, placing high demands on the lifting capacity and operating radius of the lifting equipment. Steel columns require high installation precision, and vertical deviations must generally be kept within allowable limits.

[0003] For example, in high-rise steel structure buildings, the vertical deviation of the columns is strictly required, and the deviation may be required to not exceed H / 1000 (H is the column height). However, during the actual lifting process, it is difficult to accurately control the impact of various factors such as wind force, shaking of lifting equipment, and operation of installation workers. The positioning of steel columns is also critical. It is necessary to ensure that their plane position is accurate and the position accuracy of the connection nodes with other components (such as steel beams) meets the design requirements, otherwise it will cause difficulties in subsequent construction. During the process of steel columns being in place, if temporary fixing measures are not in place, they will also cause displacement or shaking during construction, affecting the stability and safety of the structure. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic deviation correction device and a construction method suitable for the installation of steel structure columns of different shapes to solve the problems mentioned in the background technology or achieve better technical effects.

[0005] To solve the above technical problems, the inventors, through practice and summary, have arrived at the technical solution of the present invention. The present invention discloses an automatic misalignment correction device suitable for installing steel structure columns of different shapes. The device comprises a tightening strap and a hydraulic rod. The tightening strap has an opening, and one end of the tightening strap near the opening is connected to a tightening bolt. A plummet sensor is movably mounted on the right side of the tightening strap near the tightening bolt. The hydraulic rod is connected to the lower end of the tightening strap and is equipped with a hydraulic control switch. The plummet sensor and the hydraulic control switch are connected via a signal line. The plummet sensor transmits a signal to the hydraulic control switch via the signal line. Under the action of an external power source, the hydraulic control switch is activated to move the hydraulic rod to correct the misalignment of the steel structure column.

[0006] Preferably, the number of hydraulic rods is 4, and each hydraulic rod is equipped with a hydraulic control switch, which can achieve precise adjustment in different directions according to the actual position and verticality of the steel structure column.

[0007] Preferably, the hydraulic control switches on each set of hydraulic rods are connected to the hydraulic pump via a hydraulic pipeline.

[0008] Preferably, a laser device is detachably mounted on the left side of the fastening strap at a front-to-back symmetrical position. During the process of automatically correcting the position and verticality of the steel structure column by extending the hydraulic rod, the laser device is used to verify the accuracy of the automatic correction of the position and verticality of the steel structure column, greatly improving the accuracy of the automatic correction of the position and verticality of the steel structure column.

[0009] Preferably, the fastening belt is further detachably provided with a fall arrester, which can prevent the fastening belt from falling when adjusting the steel structure column, thereby further improving the installation accuracy of the steel structure column.

[0010] Preferably, a plurality of groups of sockets are detachably mounted on the fastening belt, and the laser device, the vertical meter sensor and the anti-fall device are all detachably connected to the fastening belt via the sockets.

[0014] S3: Power on the hydraulic pump, use the vertical meter sensor to collect position signals, and transmit the collected signals to the hydraulic control switch through the signal line. Under the operation of the hydraulic pump, the hydraulic rod is driven to extend and retract through the transmission of the hydraulic pipeline, and the length of the hydraulic rod is adjusted to correct the position and verticality of the steel column;

[0015] S4: Fix the steel column, tighten the steel column anchor bolts, and the lifting is completed.

[0016] Preferably, in S2, according to the actual specifications of the steel structure column, the fastening belt in the automatic deviation correction device for the steel structure column is first sleeved on the steel structure column, and then fixed by fastening bolts.

[0017] Preferably, in S3, when the hydraulic rod is extended and retracted to automatically correct the position and verticality of the steel structure column, a laser device is used for verification.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with specific embodiments.

[0051] Example 1

[0052] like Figure 1 As shown, an automatic deviation correction device suitable for installing steel structure columns of different shapes includes a fastening belt 7 and a hydraulic rod 1 movably connected to the lower end of the fastening belt 7. The fastening belt 7 is surrounded into a circular ring with a gap to adapt to steel structure columns of different diameters. A fastening bolt 8 is connected to one end of the gap of the fastening belt 7. The position of the fastening belt 7 and the steel structure column can be fixed by adjusting the fastening bolt 8. A vertical meter sensor 10 is movably installed on the right side of the fastening belt 7 near the fastening bolt 8. The vertical meter sensor 10 can be used to detect the offset of the steel structure column and achieve rapid calibration.

[0053] Preferably, in order to further improve the actual installation accuracy of the steel structure column and avoid the displacement of the steel structure column, four groups of hydraulic rods 1 are connected to the lower end of the fastening belt 7, and a hydraulic control switch 2 is installed on each group of hydraulic rods 1.

[0054] Specifically, the vertical meter sensor 10 on the fastening belt 7 is connected to the hydraulic control switch 2 on the hydraulic rod 1 through the signal line 9. The vertical meter sensor 10 transmits the signal to the hydraulic control switch 2 through the signal line 9. Under the action of external power, the hydraulic rod 1 can be moved by starting the hydraulic control switch 2 to complete the deviation correction of the steel structure column.

[0055] Preferably, the above-mentioned power is provided by a hydraulic pump 12; the hydraulic control switch 2 on each group of hydraulic rods 1 is connected to the hydraulic pump 12 through a hydraulic pipe 11. When the hydraulic pump 12 is energized, the vertical meter sensor 10 transmits a signal to the hydraulic control switch 2. After receiving the signal, the hydraulic control switch 2 will respond and use the power generated by the hydraulic pump 12 to drive the extension or contraction of the hydraulic rod 1 through the transmission of the hydraulic pipe 11, thereby realizing automatic correction of the position and verticality of the steel column.

[0056] Preferably, a laser device 6 is detachably installed at the front and rear symmetrical positions on the left side of the fastening belt 7. During the process of the hydraulic rod 1 extending to automatically correct the position and verticality of the steel structure column, the laser device 6 is used for verification. The laser device 6 emits laser light to the ground and feeds back the position and verticality information of the steel structure column according to the position of the bright light reflected from the ground, which greatly improves the accuracy of the automatic correction of the position and verticality of the steel structure column.

[0057] Preferably, a fall arrester 13 is detachably mounted on the fastening belt 7. The fall arrester 13 is used to fix the fastening belt 7, thereby preventing the fastening belt from falling when adjusting the steel structure column, thereby further improving the installation accuracy of the steel structure column.

[0058] Preferably, a plurality of groups of jacks 5 are detachably mounted on the fastening belt 7 , and the laser device 6 , the vertical meter sensor 10 and the anti-fall device 13 are all detachably connected to the fastening belt 7 via the jacks 5 .

[0059] Example 2

[0060] The assembly method of the steel column automatic deviation correction device proposed by the present invention comprises the following steps:

[0061] Step 1: Insert the socket 5 into the fastening belt 7, and install the laser device 6, the vertical meter sensor 10 and the anti-drop device 13;

[0062] Step 2: Adjust the fastening belt 7 to a certain height (according to the actual situation, the fastening belt 7 can fix the steel structure column), and tighten the fastening bolt 8;

[0063] Step 3: Install the hydraulic rod 1, adjust and fix the rod foot, and install the steel foot plate fixing rod 3;

[0064] Step 4: Connect the plummet sensor 10 to the hydraulic control switch 2 with signal cable 9, and connect the hydraulic control switch 2 to the hydraulic pump 12 with hydraulic piping 11. When the hydraulic pump is powered on, the plummet sensor 10 transmits a signal to the hydraulic control switch 2, which extends the hydraulic rod 1 to automatically correct the column's position and verticality. This process is verified using a laser.

[0065] The present invention is easy to operate and can efficiently complete the steel column hoisting operation. Safety is guaranteed during the operation process, and while improving work efficiency, the stability and safety of the steel column hoisting are also guaranteed.

[0066] Example 3

[0067] A construction method for an automatic deviation correction device suitable for installing steel structure columns of different shapes, comprising the following steps:

[0068] (1) Use a crane to lift the target steel structure column to the designated location;

[0069] (2) The automatic deviation correction device for the steel structure column is fixed to the steel column by fastening bolts 8, and the crane keeps the steel column in a suspended state;

[0070] (3) The hydraulic pump 12 is powered on, and the vertical meter sensor collects position signals and transmits the collected signals to the hydraulic control switch 2 through the signal line 9. The power generated by the hydraulic pump 12 is transmitted through the hydraulic pipe 11 to drive the extension or contraction of the hydraulic rod 1 to automatically adjust the length of the hydraulic rod and correct the position and verticality of the steel column;

[0071] (4) Fix the steel column, tighten the steel column anchor bolts, and the lifting is completed.

Once the plummet sensor stabilizes, the column's verticality is adjusted, and the entire column misalignment correction process is automated. This invention addresses issues such as difficulty controlling steel column installation accuracy, difficulty in hoisting operations, and wobbling steel columns during installation, accelerating construction progress and improving acceptance rates.
