Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a butt joint and assembly structure. Background Technique

[0002] Steel structure support columns are the main components used to support and stabilize the structure in steel structure buildings. The support columns can bear the self-weight of the building and external loads, such as wind loads and seismic actions, and transfer them to the foundation; currently, during the installation process of steel structure support columns, it is necessary to hoist steel columns for butt joint and assembly.

[0003] The utility model patent with the authorization announcement number of CN209353754U discloses a correction device for steel column butt joints. The correction device for steel column butt joints includes a support seat arranged at the butt joint position of the lower steel column and the upper steel column. The support seat is formed with a lower fixing surface that is detachably attached and fixed to the side surface of the lower steel column; and a vertical jack that is detachably vertically fixed to the support seat and corresponds to the upper steel column. The vertical jack includes a vertical cylinder body fixed to the support seat and a vertical push rod telescopically connected to the vertical cylinder body. The vertical push rod is formed with an upper fixing surface that is detachably attached and fixed to the side surface of the upper steel column. The upper fixing surface and the lower fixing surface are located in the same vertical plane, so that the corresponding side surfaces of the upper steel column and the lower steel column are located in the same vertical plane, and by telescoping the vertical push rod, the vertical movement of the upper steel column is driven to correct the position of the upper steel column. By using the support seat to be detachably fixed to the lower steel column through the lower fixing surface and to the upper steel column through the upper fixing surface, the lateral position of the upper steel column can be restricted by the upper fixing surface, and the lateral position of the lower steel column can be restricted by the lower fixing surface. Since the upper fixing surface and the lower fixing surface are located in the same vertical plane, the corresponding side surfaces of the upper steel column and the lower steel column can be restricted to be located in the same vertical plane to adjust the horizontal position of the upper steel column. The vertical jack is detachably vertically fixed to the support seat and corresponds to the upper steel column, so that the vertical movement of the upper steel column can be driven by the telescopic movement of the vertical push rod to adjust the vertical position of the upper steel column. Thus, it can be used to adjust the position of the upper steel column butt-jointed to the top of the lower steel column, achieve butt joint correction, and improve the welding quality of the steel column butt joint. Therefore, by using this device, the problems in the prior art that when correcting the assembly of steel columns, positioning cards are welded up and down around the steel columns, which damages the steel columns, and cutting off the positioning cards causes the surface of the steel columns to be uneven, affecting the welding quality after the steel column butt joint, can be solved.

[0004] Although the correction device for butt joint of steel columns can improve the welding quality of butt joint of steel columns, there are still the following problems in the actual use of this device: The device only sets a butt joint structure on one side between two steel columns, and the correction effect of this structure is limited, which cannot guarantee the accuracy of the butt joint between two steel columns. In addition, the bearing capacity of this structure is relatively limited and cannot fully meet the strength requirements for the butt joint between two steel columns. In the case of long-term use or under large loads, it will have an adverse impact on the overall performance of the steel structure. In view of this, we propose a butt joint assembly structure.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] This embodiment provides a technical solution:

[0031] Please refer to Figures 1-6As shown in the figure, a docking and assembly structure includes a lower column 1. Above the lower column 1, there is an upper column 2. One end of the lower column 1 and the upper column 2 close to each other has an opening respectively, and openings are provided on both sides of the opening. On both sides of the lower column 1 and the upper column 2, there are top plates 392 respectively. On each top plate 392, there is a connecting bolt 39 respectively. Two connecting nuts 391 are screwed on each connecting bolt 39; There is an adjusting part 3 between the lower column 1 and the upper column 2; The adjusting part 3 includes two side plates 30 that are symmetrical to each other and can be clamped on both sides of the lower column 1 and the upper column 2. Horizontal plates 31 are fixed at the upper and lower ends of the two side plates 30 respectively. A connecting hole 311 for the corresponding connecting bolt 39 to pass through is opened on the horizontal plate 31, and the two connecting nuts 391 on the connecting bolt 39 are respectively located on the upper and lower sides of the horizontal plate 31. Two spaced connecting plates 32 are arranged between the two side plates 30; A bidirectional lead screw 33 is rotatably installed between the two connecting plates 32. Movable seats 35 that can move horizontally are respectively threadedly connected to two threaded sections of the bidirectional lead screw 33; Two movable plates 37 are respectively slidably installed on the upper and lower sides of the movable seat 35 between the two side plates 30. In the middle of one side of each movable plate 37 facing the movable seat 35, two pairs of support rods 36 are respectively rotatably connected through hinge seats 361. The other end of each pair of support rods 36 is respectively rotatably connected to the corresponding movable seat 35 through a hinge seat 361. Connecting frames 38 are respectively arranged on the sides of the two movable plates 37 away from each other. The connecting frames 38 can be movably inserted into the end openings of the lower column 1 or the upper column 2. A tie bolt 381 is passed through the connecting frame 38. The tie bolt 381 can movably penetrate the corresponding opening and a locking nut 382 is threadedly screwed at its end.

[0032] In this embodiment, the side plates 30, the horizontal plates 31 and the connecting plates 32 are of an integrally formed structure, and the included angle between the side plates 30 and the horizontal plates 31 is 90°. The integrally formed design reduces the connection gaps between components and improves the overall stability and strength.

[0033] In this embodiment, at the connection between the upper top plate 392 and the upper column 2 and at the connection between the lower top plate 392 and the lower column 1, second reinforcing blocks 393 are tightly welded. The overall shape of the second reinforcing blocks 393 is triangular. The second reinforcing blocks 393 provide additional support force and enhance the connection strength between the top plate 392 and the upper column 2.

[0034] In this embodiment, the front end of the bidirectional lead screw 33 passes through the connecting plate 32 and is coaxially fixed with a screwing block. The screwing block design makes the rotation adjustment of the bidirectional lead screw 33 more convenient and fast.

[0035] In this embodiment, a column base 10 is fixed to the bottom end of the lower column 1. Mounting holes 101 are provided at the four corners of the column base 10. A plurality of first reinforcing blocks 11 are tightly welded at the connection between the column base 10 and the lower column 1. The design of the mounting holes 101 enables the lower column 1 to be conveniently fixed to the foundation or other support structures. The first reinforcing blocks 11 increase the load-bearing capacity at the connection between the column base 10 and the lower column 1, ensuring the structural stability.

[0036] In this embodiment, a column head 20 is fixed to the top end of the upper column 2. Fixing holes 201 are provided at the four corners of the column head 20. The design of the fixing holes 201 enables the upper column 2 to be conveniently connected to other structures or devices.

[0037] In this embodiment, guide rods 34 are respectively fixed and installed on both sides of the bidirectional lead screw 33 between the two connecting plates 32. The guide rods 34 are slidably connected to the movable seats 35. The guide rods 34 provide a stable sliding track for the movable seats 35, ensuring the smoothness during the adjustment process and effectively preventing the movable seats 35 from shifting or shaking during the adjustment process.

[0038] In this embodiment, the movable plate 37 and the connecting frame 38 are of an integrally formed structure. The cross-sectional shape of the connecting frame 38 is U-shaped, and the size of the connecting frame 38 is adapted to the bottom opening size of the upper column 2 and the top opening size of the lower column 1. The integrally formed design increases the connection strength between the movable plate 37 and the connecting frame 38, and the adapted size ensures the tightness and stability of the connection.

[0039] It should be added that the overall shape of the wrench block in this embodiment is regular hexagonal, and this design facilitates the rotation of the bidirectional lead screw 33 by a wrench, improving the operation convenience.

[0040] During specific use, the user first places the adjusting part 3 between the upper column 2 and the lower column 1. Subsequently, the user inserts the connecting frames 38 on the upper and lower sides respectively into the bottom opening of the upper column 2 and the top opening of the lower column 1, and passes the tie bolts 381 through the openings of the upper column 2 and the lower column 1 and the connecting frames 38, and then tightens the lock nuts 382 on the tie bolts 381. The connecting frames 38 are then fixed to the upper column 2 and the lower column 1. Subsequently, the user tightens one of the connecting nuts 391 on the connecting bolt 39. Then the user rotates the wrench block with a wrench, and the wrench block drives the bidirectional lead screw 33 to rotate. As the bidirectional lead screw 33 rotates, the two movable seats 35 move synchronously in opposite directions. The movable seats 35 simultaneously drive the support rods 36 to move, and the support rods 36 drive the upper column 2 to approach the lower column 1. At the same time, the connecting bolt 39 passes through the connecting hole 311. When the connecting nut 391 abuts against the cross plate 31, the user stops rotating the wrench block. Finally, the user tightens the other connecting nut 391 on the connecting bolt 39. At this time, the adjacent two connecting nuts 391 clamp the cross plate 31, and the installation is completed.
