Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to an adjustable support for portal steel structure installation. Background Technology

[0002] During the construction process, columns are the core load-bearing components of the spatial structural system. Their installation must meet strict verticality standards and spatial geometric positioning accuracy. As a key control node for the safety of the main building structure, the installation deviation of steel columns directly affects the load transfer path and seismic performance.

[0003] The installation of steel structure columns mainly relies on crane hoisting, temporary support for fixation, and measurement of verticality using equipment such as total station. Verticality is then adjusted manually with the help of jacks or mechanical shims. However, manual calibration is inefficient and has poor accuracy, requiring repeated calibration and adjustment. This repeated adjustment process increases the wear rate of materials such as shims. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable support for portal steel structure installation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable support for a portal steel structure, comprising a steel column, the lower end of which is connected to the ground via pre-embedded anchor bolts, and a pre-embedded part connected to the ground installed on both sides of the pre-embedded anchor bolts, the upper end of which has a groove, a sliding block slidably connected inside the groove, an adjusting rod installed on the upper end of the sliding block, a second plate installed on the end of the adjusting rod near the steel column, a support column installed on the lower end of the adjusting rod, and a synchronous jack installed on the lower end of the support column.

[0006] Preferably, the adjusting inclined rod includes a fixed inclined plate, a lifting inclined plate, and a sliding rod. The upper end of the sliding block is fixedly installed with a fixed inclined plate, the upper end of the fixed inclined plate is installed with a sliding rod, the outside of the sliding rod is slidably connected with a lifting inclined plate, and the lower end of the lifting inclined plate is connected to the upper end of the support column.

[0007] Preferably, the side wall of the sliding block is provided with a threaded groove, and a first threaded rod is threadedly connected inside the threaded groove. A steering rod is installed at one end of the outer side of the first threaded rod, and a first plate is rotatably installed at the other end of the first threaded rod. A clamping plate is installed on both sides of the first plate.

[0008] Preferably, threaded grooves are provided on both side walls of the first plate, and a second threaded rod is threadedly connected inside the threaded groove. The second threaded rod is threadedly connected to the clamping plate, and two guide rods are symmetrically installed between the clamping plate and the side wall of the first plate with the second threaded rod as the center.

[0009] Preferably, the side wall of the support column is provided with a through groove, the width of which is greater than the size of the first threaded rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This portal steel structure uses adjustable supports. During use, the steel column is connected to the pre-embedded anchor bolts, and the position of the sliding block is moved. The sliding block drives the adjusting rod to move towards the side wall of the steel column until the second plate contacts the side wall. At this point, synchronous jacks are installed on both sides of the steel column. The upper end of the jacks is connected to the lower end of the adjusting rod through a support column. By synchronously changing the height of the adjusting rod with two synchronous jacks, the two adjusting rods will drive the two second plates to move synchronously longitudinally along the side wall of the steel column. This allows for synchronous pressure correction of the verticality of the steel column's side wall from both sides. Combined with equipment such as a total station, the verticality of the steel column can be measured. Compared to manual calibration and correction, this method is more efficient, more accurate, and can reduce material waste to some extent.

[0012] 2. This portal steel structure is equipped with an adjustable support. The distance between the two clamping plates and the first plate can be adjusted by the second threaded rod, thereby increasing or decreasing the distance between the two clamping plates. This allows the two clamping plates to be used for steel columns of different sizes within a certain range, increasing the applicability of the device and meeting the verticality adjustment needs of steel columns of most sizes.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3As shown, this embodiment of the adjustable support for the portal steel structure includes a steel column 1. The lower end of the steel column 1 is connected to the ground via pre-embedded anchor bolts 2. The pre-embedded anchor bolts 2 specifically refer to pre-embedded anchors connected by threads. On both sides of the pre-embedded anchor bolts 2, there is a pre-embedded part 3 connected to the ground. The pre-embedded part 3 has the same function as the pre-embedded anchor bolt 2, connecting to the ground. The upper end of the pre-embedded part 3 has a groove, and a sliding block 4 is slidably connected inside the groove. The sliding block 4 can slide inside the groove. It should be noted that the sliding block 4 has a certain friction with the side wall of the groove and can only slide inside the groove under the action of external force. An adjusting rod 9 is installed on the upper end of the sliding block 4. One end of the adjusting rod 9 is fixedly connected to the sliding block 4, allowing for a certain degree of adjustment in the vertical direction. A second plate 15 is installed on the end of the adjusting rod 9 near the steel column 1. The second plate 15 is tightly fitted to the side wall of the steel column 1 for adjustment. A support column 10 is installed at the lower end of the diagonal rod 9, and a synchronous jack 8 is installed at the lower end of the support column 10. The oil inlet and outlet of the two synchronous jacks 8 are connected in parallel and the oil flow is controlled by a proportional valve. The proportional valve is installed inside the two synchronous jacks 8, which can adjust the oil flow rate into the cylinder of the two synchronous jacks 8, so that the two synchronous jacks 8 can be adjusted and raised synchronously. The synchronous adjustment of the two synchronous jacks 8 drives the support column 10 to move synchronously. The support column 10 drives the adjusting diagonal rod 9 to move synchronously. The adjusting diagonal rod 9 drives the second plate 15 to move synchronously. The two adjusting diagonal rods 9 will drive the two second plates 15 to move synchronously longitudinally along the side wall of the steel column 1, thereby synchronously correcting the verticality of the side wall of the steel column 1 from both sides. In conjunction with equipment such as a total station, the verticality of the steel column 1 can be measured. Compared with manual calibration and correction, it is more efficient, more accurate, and can reduce material waste to a certain extent.

[0020] Specifically, the adjusting inclined rod 9 includes a fixed inclined plate 901, a lifting inclined plate 902, and a sliding rod 903. The fixed inclined plate 901 is fixedly installed on the upper end of the sliding block 4, and the sliding rod 903 is installed on the upper end of the fixed inclined plate 901. The lifting inclined plate 902 is slidably connected to the outside of the sliding rod 903. The position of the fixed inclined plate 901 is fixed. When the lifting inclined plate 902 is subjected to an upward force from the support column 10, the lifting inclined plate 902 will move within a certain range along the direction of the sliding rod 903. It should be noted that a limit plate is provided at the connection between the sliding rod 903 and the slide groove. The sliding rod 903 can slide through the slide groove, but it cannot completely leave the interior of the slide groove.

[0021] Furthermore, the side wall of the sliding block 4 is provided with a threaded groove, and the inside of the threaded groove is threadedly connected to a first threaded rod 5. A steering rod 6 is installed at one end of the outer side of the first threaded rod 5, and a first plate 7 is rotatably installed at the other end of the first threaded rod 5. A clamping plate 11 is installed on both sides of the first plate 7. The two clamping plates 11 can clamp the two sides of the steel column 1. Since the clamping plates 11 are connected to the first plate 7, the positions of the first plate 7, the first threaded rod 5, and the sliding block 4 can be fixed.

[0022] Furthermore, threaded grooves are provided on both side walls of the first plate 7, and a second threaded rod 12 is threadedly connected inside the threaded groove. The second threaded rod 12 is threadedly connected to the clamping plate 11. Two guide rods 13 are symmetrically installed between the clamping plate 11 and the side wall of the first plate 7, with the second threaded rod 12 as the center. The distance between the two clamping plates 11 and the first plate 7 can be adjusted by the second threaded rod 12, thereby increasing or decreasing the distance between the two clamping plates 11. This allows the two clamping plates 11 to be applicable to steel columns 1 of different sizes within a certain range, increasing the applicability of the device and meeting the verticality adjustment requirements of steel columns 1 of most sizes. The guide rod 13 is inserted inside the first plate 7. When the clamping plate 11 is moved outward, the guide rod 13 will move outward synchronously. The guide rod 13 cannot completely leave the interior of the first plate 7. Similar to the structure of the slide rod 903, the guide rod 13 can play a guiding role.

[0023] Furthermore, the side wall of the support column 10 is provided with a through groove 14. The width of the through groove 14 is greater than the size of the first threaded rod 5. The first threaded rod 5 passes through the through groove 14. The through groove 14 can prevent contact between the support column 10 and the first threaded rod 5.

[0024] Furthermore, the oil inlet and outlet of the two synchronous jacks 8 are connected in parallel, and the oil flow is controlled by a proportional valve. The proportional valve is installed inside the two synchronous jacks 8, which can adjust the oil flow rate into the cylinder of the two synchronous jacks 8, so that the two synchronous jacks 8 can be adjusted synchronously for lifting and lowering.

[0025] The usage method of this embodiment is as follows: The steel column 1 is installed on the upper end of the pre-embedded anchor bolt 2, and the two sliding blocks 4 are moved. The sliding blocks 4 will drive the first threaded rod 5 and the first mounting plate 7 to move towards the side wall of the steel column 1 until the first mounting plate 7 contacts the side wall of the steel column 1. The position of the clamping plate 11 is adjusted by the two second threaded rods 12, so that the two clamping plates 11 clamp the steel column 1 from both sides. At this time, the positions of the first mounting plate 7, the first threaded rod 5, and the sliding blocks 4 are temporarily fixed. The first threaded rod 5 is rotated by the steering rod 6. When the first threaded rod 5 rotates… The sliding block 4 will move along the length of the first threaded rod 5, thereby driving the adjusting rod 9 to move towards the side wall of the steel column 1 until the second plate 15 contacts the side wall of the steel column 1. It should be noted that the initial contact position of the second plate 15 with the steel column 1 is at two-thirds of the height of the steel column 1. At this time, the two synchronous jacks 8 are activated. The two synchronous jacks 8 can synchronously drive the two support columns 10 to move upward, thereby driving the adjusting rod 9 to move, and synchronously applying pressure to both sides of the steel column 1 to correct the verticality of the steel column 1.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
