Description

Technical Field

[0001] This utility model relates to the field of building steel structure construction technology, and in particular to an adjustment device for auxiliary connection during the installation of box-type columns of building steel structures. Background Technology

[0002] In the installation of steel structures, the installation of steel columns is a crucial step. For box-type steel columns, the conventional method is to install and fix the lower column first, and then hoist the upper column onto the top surface of the lower column, so that the bottom end of the upper column is aligned with the top end of the lower column. When aligning the two columns, the usual technical measures are to first use four sets of clamps to simultaneously clamp the corresponding upper column fixing plate and lower column lifting lug plate, and use bolt pairs to temporarily position the upper and lower columns. Then, tools such as pry bars, jacks, and heavy hammers are used to correct and adjust the coaxiality of the two column axes, the verticality of the upper column axis relative to the top surface of the lower column, and the horizontal elevation of the top surface of the upper column. After the correction is satisfactory, the clamps are tightened, and then the mating ends of the two columns are welded. After welding, the four sets of clamps are removed, thus completing the installation and connection of the upper and lower steel columns.

[0003] In the existing technology, the traditional installation of box-type steel columns has the disadvantages of being troublesome and inefficient during the adjustment process, as well as being labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustment device for auxiliary connection during the installation of box-type steel columns in building steel structures, so as to solve the problems mentioned in the background art, such as the troublesome adjustment process, low efficiency and high labor intensity of traditional box-type steel columns during installation.

[0006] In a preferred embodiment, the outer wall of the upper steel column is fixedly connected to one side of the upper column bearing plate, and the upper column bearing plate is provided with four sets.

[0007] In a preferred embodiment, the upper column bearing plate has a first mounting hole inside, and the inner wall of the first mounting hole is movably connected to the outer wall of the standard bolt, and the outer wall of the standard bolt is threadedly connected to the inner wall of the standard nut.

[0008] In a preferred embodiment, a lower steel column is provided at the bottom of the upper steel column, and the outer wall of the lower steel column is fixedly connected to one side of the lower column bearing plate. The lower column bearing plate is provided in four sets.

[0009] In a preferred embodiment, the lower column bearing plate has a second mounting hole inside, and the inner wall of the second mounting hole is movably connected to the outer wall of the fixing bolt, and the outer wall of the fixing bolt is threadedly connected to the inner wall of the fixing nut.

[0010] In a preferred embodiment, the outer wall of the lower steel column is provided with a support frame, and the bottom of the support frame is provided with a third mounting hole, and the inner wall of the third mounting hole is movably connected to the outer wall of the fixing bolt, and the top of the support frame is provided with a sliding hole.

[0011] In a preferred embodiment, the top of the support frame is provided with a vertical guide sleeve, and both sides of the vertical guide sleeve are fixedly connected to one end of the limiting rod. The outer wall of the limiting rod is movably connected to the inner wall of the sliding hole. The inner wall of the vertical guide sleeve is movably connected to the outer wall of the vertical adjusting screw, and the outer wall of the vertical adjusting screw is threadedly connected to the inner wall of the vertical locking nut.

[0012] In a preferred embodiment, two sets of vertical locking nuts are provided, and the two sets of vertical locking nuts are respectively located at the upper and lower ends of the vertical guide sleeve. The top end of the vertical adjusting screw is fixedly connected to the bottom of the adjusting frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model places an upper steel column above a lower steel column. When the upper steel column tilts, the support frame is fixed to the lower steel column with fixing bolts and nuts. Then, the adjusting frame is fixed to the upper steel column with standard bolts and nuts. The vertical locking nut located below the vertical guide sleeve at the tilted part is rotated. As the vertical locking nut rotates, it drives the vertical adjusting screw to move downward, which in turn drives the adjusting frame to move downward, causing the tilted part of the upper steel column to move downward, thus adjusting the upper and lower steel columns. After the angle tilt is adjusted, it is convenient to adjust when the tilt between the upper and lower steel columns deviates, increasing the adjustment efficiency.

[0014] 2. In this utility model, when the central axes of the upper and lower steel columns are not aligned, the upper steel column is moved on top of the lower steel column by rotating the horizontal adjusting nut and adjusting the horizontal adjusting screw. By adjusting the horizontal position of the offset, the central axes of the upper and lower steel columns are aligned, eliminating the need for traditional tools such as pry bars, jacks, and hammers, and making the alignment of the central axes of the upper and lower steel columns more convenient.

[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] Please see Figures 1-3This utility model provides a technical solution comprising: an upper column mechanism 1, which includes an upper steel column 101, a standard bolt 102, and a standard nut 103; a lower column mechanism 2 is provided at the bottom of the upper column mechanism 1, which includes a lower steel column 201, a fixing bolt 202, and a fixing nut 203; and an adjustment mechanism 3 is provided on the outer wall of the upper column mechanism 1, which includes a support frame 301, a vertical guide sleeve 302, a limiting rod 303, a vertical adjusting screw 304, a vertical locking nut 305, an adjustment frame 306, a horizontal adjusting nut 307, and a horizontal adjusting screw 308.

[0019] In one embodiment, the outer wall of the upper steel column 101 is fixedly connected to one side of the upper column bearing plate. The upper column bearing plate is provided with four sets of ...

[0020] Specifically: After the upper steel column 101 is placed on top of the lower steel column 201 and installed in place, if the upper steel column 101 is detected to be tilted, the support frame 301 is fixed to the lower steel column 201 by fixing bolts 202 and fixing nuts 203. Then, the adjusting frame 306 is fixed to the upper steel column 101 by standard bolts 102 and standard nuts 103. The vertical locking nut 305, which is located below the vertical guide sleeve 302 at the tilted part, is rotated. As the vertical locking nut 305 rotates, it drives the vertical adjusting screw 304 to move downward, which in turn drives the adjusting frame 306 to move downward, so that the tilted part of the upper steel column 101 moves downward, thereby correcting the tilt deviation of the upper steel column 101 relative to the lower steel column 201.

[0021] In one embodiment, a vertical guide sleeve 302 is provided at the top of the support frame 301, and both sides of the vertical guide sleeve 302 are fixedly connected to one end of the limiting rod 303. The outer wall of the limiting rod 303 is movably connected to the inner wall of the sliding hole. The inner wall of the vertical guide sleeve 302 is movably connected to the outer wall of the vertical adjusting screw 304, and the outer wall of the vertical adjusting screw 304 is threadedly connected to the inner wall of the vertical locking nut 305. Two sets of vertical locking nuts 305 are provided, and the two sets of vertical locking nuts 305 are located at the upper and lower ends of the vertical guide sleeve 302, respectively. The top end of the vertical adjusting screw 304 is fixedly connected to the bottom of the adjusting frame 306. A fourth mounting hole is opened inside the adjusting frame 306, and the inner wall of the fourth mounting hole is movably connected to the outer wall of the standard bolt 102. One side of the support frame 301 is fixedly connected to one side of the horizontal adjusting nut 307, and the inner wall of the horizontal adjusting nut 307 is threadedly connected to the outer wall of the horizontal adjusting screw 308.

[0022] Specifically: If a deviation is detected between the central axis of the upper steel column 101 and the central axis of the lower steel column 201, the upper steel column 101 is moved to the top of the lower steel column 201 by rotating the horizontal adjusting screw 308 in the horizontal adjusting nut 307, so that the deviation between the central axis of the upper steel column 101 and the central axis of the lower steel column 201 is corrected. Specifically: If the central axis of the upper steel column 101 is not aligned after the tilt deviation of the lower steel column 201 is corrected, the above steps can still be used to perform the alignment operation of the central axis of the upper steel column 101 relative to the lower steel column 201.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
