Description

Technical Field

[0001] This utility model relates to the field of steel structure column installation, and in particular to a bottom installation kit for steel structure columns. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Steel structures are connected by bolts and rivets.

[0003] When installing steel structure columns, a bottom mounting kit for the steel structure columns is required to ensure a stable connection.

[0004] Currently, when installing steel structure columns, a crane is typically used to lift the column, and then a person manually aligns the bottom of the column with the fixed base before fixing it. However, in actual use, manual alignment is not very accurate, and the verticality of the column is insufficient during alignment. This can easily cause one side of the column to contact the base first, resulting in deformation of the column. It can also cause the threaded holes of the column bottom and the base to misalign, making the next step of installation more difficult. Therefore, a bottom installation kit for steel structure columns is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bottom mounting kit for steel structure columns, which aims to improve the problem of poor alignment accuracy when manually aligning the bottom of the steel structure column with the fixed base in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a bottom mounting kit for a steel structure column, including a fixing plate, a lifting cylinder at the top of the fixing plate, a compression frame fixedly connected to the top telescopic end of the lifting cylinder, a side plate fixedly connected to the outer periphery of the fixing plate, a support assembly inside the side plate for supporting the fixing plate, a connecting rod hinged to the top of the side plate, a sliding column rotatably connected to the top of the connecting rod, a sliding sleeve elastically connected to the outside of the sliding column via a limiting spring, and a limiting assembly fixedly connected to the outside of the sliding sleeve for limiting the position of the steel structure column.

[0007] As a further description of the above technical solution:

[0008] The support assembly includes a support frame, a worm gear rotatably connected inside the support frame, a handwheel provided on the outside of the worm gear, a worm wheel meshing on the left side of the worm gear, a threaded rod fixedly connected inside the worm wheel, and a support foot threadedly connected to the outer circumference of the threaded rod.

[0009] As a further description of the above technical solution:

[0010] The bottom end of the extrusion frame is set as an arc surface, and the bottom surface of the extrusion frame is in contact with the upper side of the connecting rod.

[0011] As a further description of the above technical solution:

[0012] One end of the limiting spring is fixedly connected to the outside of the sliding column, and the other end of the sliding column is fixedly connected to the inner wall of the sliding sleeve. The outer periphery of the sliding column is slidably connected to the inside of the sliding sleeve.

[0013] As a further description of the above technical solution:

[0014] The limiting component includes a limiting angle, the outer periphery of which is fixedly connected to the outer side of the sliding sleeve, and a rubber wheel is provided on the inner side of the limiting angle.

[0015] As a further description of the above technical solution:

[0016] The limiting angle is set as a right angle and the inner wall of the side is provided with a rectangular groove. The two sets of rubber wheels are set perpendicularly to each other in the groove of the inner wall of the limiting angle.

[0017] As a further description of the above technical solution:

[0018] A level is installed at the top of the fixed plate.

[0019] As a further description of the above technical solution:

[0020] The threaded rod is rotatably connected to the inside of the side plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a connecting rod, a pressing frame, a sliding sleeve and other mechanisms, the lifting cylinder is opened, which drives the pressing frame to press down and drives the limiting angle to clamp and limit the steel structure column inward. At this time, moving the steel structure column downward can ensure the verticality of the steel structure column and ensure that the steel structure column is aligned with the fixed base, which is more convenient to use.

[0023] 2. In this utility model, by setting up mechanisms such as worm gear, worm, and threaded rod, the handwheel on one side is rotated according to the display of the level, and the worm gear and worm precisely drive the threaded rod to rotate, so that the threaded rod can drive the fixed plate to rise and fall, thereby leveling the fixed plate and making the installation more precise.

[0030] 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.

[0031] Reference Figures 1-2 This utility model provides an embodiment of a bottom mounting kit for a steel structure column, including a fixing plate 1 for fixed connection. The fixing plate 1 has a rectangular frame inside to facilitate the passage of the fixing base of the steel structure column. A lifting cylinder 2 is mounted on the top of the fixing plate 1. Four sets of lifting cylinders 2 are evenly distributed at the four corners of the fixing plate 1. A pressing frame 3 is fixedly connected to the top telescopic end of the lifting cylinder 2. Activating the lifting cylinder 2 allows the pressing frame 3 to move precisely up and down. Side plates 4 are fixedly connected to the outer periphery of the fixing plate 1. Four sets of side plates 4 are fixedly connected to the four sides of the fixing plate 1. A connecting rod 5 is hinged to the top of the side plate 4. The bottom surface of the pressing frame 3 contacts the upper side of the connecting rod 5. The bottom end of the pressing frame 3 is curved to facilitate contact with the connecting rod 5. A sliding column 6 is rotatably connected to the top of the connecting rod 5.

[0032] Reference Figures 2-3A sliding sleeve 8 is elastically connected to the outside of the sliding column 6 via a limiting spring 7. Two sets of sliding sleeves 8 are symmetrically arranged at both ends of the sliding column 6. One end of the limiting spring 7 is fixedly connected to the outside of the sliding column 6. When the sliding sleeve 8 is not under force, the limiting spring 7 will push the sliding sleeve 8 outwards. The other end of the sliding column 6 is fixedly connected to the inner wall of the sliding sleeve 8. The outer periphery of the sliding column 6 is slidably connected to the inside of the sliding sleeve 8, allowing the sliding sleeve 8 to slide along the outer periphery of the sliding column 6. A sliding sleeve 8 is fixedly connected to the outside of the sliding sleeve 8. The limiting component is used to restrict the position of the steel structure column. The limiting component includes a limiting angle 9, which is fixedly connected to the outer side of the sliding sleeve 8. A rubber wheel 10 is provided on the inner side of the limiting angle 9. The rubber wheel 10 contacts the four corners of the steel structure column to restrict the position of the steel structure column, while allowing the steel structure column to move up and down. The limiting angle 9 is set as a right angle and has a rectangular groove on its inner side wall. Two sets of rubber wheels 10 are perpendicularly set in the groove on the inner side wall of the limiting angle 9, so that the steel structure column can be aligned with the fixed base.

[0033] Reference Figure 1 and Figure 4 A level 17 is installed at the top of the fixed plate 1, which can determine whether the fixed plate 1 is level based on the bubble inside the level 17. A support assembly is installed inside the side plate 4 to support the fixed plate 1. The support assembly includes a support frame 11 for fixed support. A worm gear 12 is rotatably connected inside the support frame 11. A handwheel 13 for easy rotation is installed on the outside of the worm gear 12. A worm wheel 14 is engaged on the left side of the worm gear 12. The rotation of the worm gear 12 can drive the worm wheel 14 to rotate, and the rotation is relatively high. For one rotation of the worm wheel 14, the worm gear 12 needs to rotate multiple times. A threaded rod 15 is fixedly connected inside the worm wheel 14. The outer periphery of the threaded rod 15 is rotatably connected to the inside of the side plate 4. The rotation of the threaded rod 15 can slide up and down on the inner wall of the side plate 4. A support foot 16 for fixed support is threadedly connected to the outer periphery of the threaded rod 15.

[0034] Working principle: To ensure the bottom of the steel structure column is aligned with the mounting base, first align the fixing plate 1 with the fixed base of the steel structure column. Use a crane to lift the steel structure column and move it inside the four sets of limiting angles 9. At this time, activate the lifting cylinder 2. The telescopic end of the top of the lifting cylinder 2 drives the pressing frame 3 to move downward. The pressing frame 3 moves downward to press the connecting rod 5. The top of the connecting rod 5 moves downward and inward, driving the four sets of limiting angles 9 to move inward simultaneously. When the rubber wheels 10 on the inner side of the four sets of limiting angles 9 are in contact with the outer periphery of the steel structure column, moving the steel structure column downward at this time can ensure the verticality of the steel structure column and ensure that the steel structure column is aligned with the fixed base, which is relatively convenient to use. To ensure that the fixing plate 1 is level with the bottom surface, align the fixing plate 1 with the fixing base. Observe the level 17 and confirm the position of the bubble on the level 17. Select one side plate 4 for adjustment according to the position of the bubble. Then, rotate the handwheel 13 on the top of the side plate 4 to be adjusted. The handwheel 13 drives the worm gear 12 to rotate, the worm gear 12 drives the worm wheel 14 to rotate, and the worm wheel 14 drives the threaded rod 15 to rotate. The threaded rod 15 moves up and down along the inner wall of the support foot 16, which can easily level the fixing plate 1 and make the installation more accurate.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
