Description

Technical Field

[0001] This application relates to the field of prefabricated building technology, specifically to a leveling device for column connection. Background Technology

[0002] In related technologies, steel column connection nodes typically consist of two parts: an upper steel column and a lower steel column. During construction, the lower steel column is installed first, followed by the upper steel column being hoisted directly above the lower steel column and lowered vertically to its top. The lower steel column usually has an end cap plate flush with the column's cross-section. After the upper steel column is lowered, it should make surface contact with the top of the lower steel column and be temporarily secured using ear plates, connecting plates, and bolts pre-welded to the column body in the factory. After the upper steel column is placed on top of the lower column, due to the inability of the crane to precisely align the upper and lower steel columns, the following misalignments often occur after hoisting and positioning: misalignment of the upper and lower column planes; misalignment of the upper and lower column plane angles; and misalignment of the upper column axis relative to the lower column axis (not on the same straight line). These misalignments require secondary engineering correction. For plane and angle misalignment correction between the upper and lower columns, the traditional method is to erect horizontal jacks at different positions between the upper and lower columns; for angle misalignment, vertical jacks are erected at different positions between the upper and lower columns. This calibration method involves complicated procedures, requires a large amount of auxiliary materials, and necessitates workers with certain engineering experience to operate and complete it. Summary of the Invention

[0003] This application provides a leveling device for column connection, which can facilitate leveling and thus better solve the problem of temporary anti-overturning and tilt angle correction (leveling) between two steel columns.

[0004] The leveling device for column connection provided in this application includes multiple leveling parts. The leveling parts are used to adjust the angle of the first column relative to the second column in the vertical direction. The first column and the second column are connected. In the connected state, the first column is located above the second column, and the first column part is inserted into the second column. The leveling part includes a first connector, a second connector, a first rod, and a plurality of limiting members. The first connector and the second connector are respectively fixedly disposed on the side walls of the first column and the second column, and are arranged at intervals relative to each other. The length direction of the first rod extends along the length direction of the first column and the second column, and the first rod is inserted into the oppositely arranged first connector and the second connector. The limiting members can adjust the length of the first rod between the first connector and the second connector, thereby adjusting the angle of the first column.

[0005] In addition, the leveling device for column connection provided in this application may also have the following additional technical features: In one alternative embodiment, the first rod is a threaded rod, and the limiting member includes a first nut and a second nut. The first nut and the second nut are screwed onto the first rod, and the first nut is located on the top side of the first connecting member, while the second nut is located on the bottom side of the first connecting member. The first nut and the second nut have a fixed state and an adjustable state with the first rod. In the fixed state, the first nut and the second nut are respectively close to the two sides of the first connector. In the adjustable state, the first nut has a preset distance from the first connector, and the second nut moves closer to or further away from the first connector to adjust the length of the first rod.

[0006] In one alternative embodiment, the limiting member further includes a third nut and a fourth nut, which are screwed onto the first rod respectively. The third nut is located on the top side of the second connector, and the fourth nut is located on the bottom side of the second connector. The third nut and the fourth nut are respectively close to the two sides of the second connector.

[0007] In one alternative embodiment, the first connector includes a first plate that is welded to the first column, the first plate having a first screw hole with the opening penetrating the side wall of the first plate; the second connector includes a second plate that is welded to the second column, the second plate having a second screw hole with the opening penetrating the side wall of the second plate.

[0008] In one alternative embodiment, the first connector further includes a first reinforcing plate, which is welded to the sidewalls of the first plate and the first column respectively. The second connector further includes a second reinforcing plate, which is welded to the sidewalls of the second plate and the second column respectively.

[0009] In one alternative embodiment, multiple leveling parts are respectively disposed on the sidewalls of the first column and the second column on opposite sides, and at least two leveling parts are disposed on one sidewall.

[0010] In one alternative embodiment, the first column includes a first steel hoop and a positioning tenon, the positioning tenon being fixedly disposed on the inner wall of the first steel hoop, and the positioning tenon being partially exposed outside the first steel hoop; the second column includes a second steel hoop and an inner lining eaves, the inner lining eaves being fixedly disposed on the inner wall of the second steel hoop, and a preset distance being between the inner lining eaves and the open end of the second steel hoop; in the connected state, the positioning tenon is at least partially inserted into the second steel hoop, and the end of the positioning tenon abuts against the inner lining eaves.

[0011] In one alternative embodiment, the first column and / or the second column further includes a steel column or a reinforced concrete column; there is a first gap between the end of the first steel hoop and the end of the second steel hoop, and after being leveled by the leveling part, the first steel hoop and the second steel hoop are welded together by welding material filled in the first gap, and the leveling part is removed after the welding connection.

[0012] The beneficial effects of this application are as follows: The leveling device for column connection in this application replaces the complex process of temporarily setting up multiple horizontal and vertical jacks at different locations in the traditional method with a leveling part (including a first connector, a second connector, a first rod, and a limiting member). By simply adjusting the limiting member, the effective length of the first rod can be controlled, thereby adjusting the angle of the first column in the vertical direction. This ensures that the axes of the first and second columns do not tilt. This correction method is simpler and more efficient, reducing adjustment time and manpower, and lowering adjustment costs. Furthermore, the plug-in connection between the first and second columns allows for a more precise connection, reducing the need to correct planar misalignment and angular misalignment, and improving installation efficiency.

[0022] like Figure 1-5As shown in the figure, this application embodiment provides a leveling device for column connection. The leveling device for column connection includes multiple leveling parts 1. The leveling parts 1 are used to adjust the angle of the first column 2 relative to the second column 3 in the vertical direction. The first column 2 and the second column 3 are in a connected state. In the connected state, the first column 2 is located above the second column 3, and the first column 2 is partially inserted into the second column 3. The leveling part 1 includes a first connector 11, a second connector 12, a first rod 13, and multiple limiting members 14. The first connector 11 and the second connector 12 are respectively fixedly disposed on the side walls of the first column 2 and the second column 3, and the first connector 11 and the second connector 12 are arranged relatively at intervals. The length direction of the first rod 13 extends along the length direction of the first column 2 and the second column 3, and the first rod 13 is inserted into the relatively arranged first connector 11 and the second connector 12. The limiting members 14 can adjust the length of the first rod 13 between the first connector 11 and the second connector 12, thereby adjusting the angle of the first column 2. It should be noted that the cross-sections of the first column 2 and the second column 3 can be rectangular or regular polygonal, or circular. This article does not specifically limit the specific shapes of the first column 2 and the second column 3.

[0023] In this embodiment, the leveling device connecting the columns replaces the complex process of temporarily setting up multiple horizontal and vertical jacks at different locations in the traditional method with the leveling part 1 (including the first connecting member 11, the second connecting member 12, the first rod 13, and the limiting member 14). By simply adjusting the limiting member 14, the effective length of the first rod 13 can be controlled, thereby adjusting the angle of the first column 2 in the horizontal direction, so that the axes of the first column 2 and the second column 3 tend to be aligned. This correction method is simpler and more efficient, reducing adjustment time and manpower, and lowering adjustment costs. In addition, the plug-in connection between the first column 2 and the second column 3 also makes the connection between them more precise, reducing the correction work for planar misalignment and planar angular misalignment, and improving installation efficiency.

[0024] like Figure 1-4As shown, in one specific embodiment, the first rod 13 is a threaded rod, and the limiting member 14 includes a first nut 141 and a second nut 142. The first nut 141 and the second nut 142 are respectively screwed onto the first rod 13, and the first nut 141 is located on the top side of the first connecting member 11, and the second nut 142 is located on the bottom side of the first connecting member 11. The first nut 141 and the second nut 142 have a fixed state and an adjustable state with the first rod 13. In the fixed state, the first nut 141 and the second nut 142 are respectively close to the two sides of the first connecting member 11. In the adjustable state, there is a preset distance between the first nut 141 and the first connecting member 11, and the second nut 142 moves closer to or further away from the first connecting member 11 to adjust the length of the first rod 13.

[0025] like Figure 1-4 As shown, in one specific embodiment, the limiting member 14 further includes a third nut 143 and a fourth nut 144. The third nut 143 and the fourth nut 144 are screwed onto the first rod 13, with the third nut 143 located on the top side of the second connector 12 and the fourth nut 144 located on the bottom side of the second connector 12. The third nut 143 and the fourth nut 144 are respectively close to both sides of the second connector 12. After the upper column 2 and the lower column 3 are connected and engaged with the first rod 13, the two relatively outer nuts 141 and 144 are immediately tightened, which can connect the upper and lower columns into one unit, preventing the upper column from tilting due to temporary horizontal forces such as earthquakes and wind loads during construction. This replaces the function of connecting the ear plate using a connecting plate in traditional steel column connections. The screw is also a component used for adjusting the upper column. This temporary connection and leveling scheme uses less steel material.

[0026] like Figure 1-4 As shown, in one specific embodiment, the first connecting member 11 includes a first plate 111, which is welded to the first column 2. The first plate 111 has a first screw hole, the opening of which penetrates the side wall of the first plate 111. The second connecting member 12 includes a second plate 121, which is welded to the second column 3. The second plate 121 has a second screw hole, the opening of which penetrates the side wall of the second plate 121. The first screw hole and the second screw hole respectively provided on the first plate 111 and the second plate 121 allow the first rod 13 to be quickly inserted and fixed, simplifying the assembly process. At the same time, the welding connection method ensures a firm connection between the corresponding connecting member and the corresponding column, improving the load-bearing capacity and deformation resistance of the overall structure.

[0027] like Figure 2-4As shown, in one specific embodiment, the first connecting member 11 further includes a first reinforcing plate 112, which is welded to the side walls of the first plate 111 and the first column 2, respectively. The second connecting member 12 further includes a second reinforcing plate 122, which is welded to the side walls of the second plate 121 and the second column 3, respectively. Furthermore, multiple leveling parts 1 are respectively disposed on the side walls of the first column 2 and the second column 3 on opposite sides, with at least two leveling parts 1 on each side wall. The placement of the first reinforcing plate 112 and the second reinforcing plate 122 significantly improves the bending and shear strength of the first connecting member 11 and the second connecting member 12, preventing weld cracking or plate deformation caused by local stress concentration during leveling. In addition, the symmetrical arrangement of the multiple leveling parts 1 further enhances the uniformity of the leveling force, avoiding column distortion caused by single-point adjustment, and ensuring the balance and controllability of the leveling process.

[0028] like Figure 5 As shown, in one specific embodiment, the first column 2 includes a first steel hoop 21 and a positioning tenon 22. The positioning tenon 22 is fixedly disposed on the inner wall of the first steel hoop 21, and a portion of the positioning tenon 22 is exposed outside the first steel hoop 21. The second column 3 includes a second steel hoop 31 and an inner lining eaves 32. The inner lining eaves 32 is fixedly disposed on the inner wall of the second steel hoop 31, and a preset distance exists between the inner lining eaves 32 and the open end of the second steel hoop 31. In the connected state, the positioning tenon 22 is at least partially inserted into the second steel hoop 31, and the end of the positioning tenon 22 abuts against the inner lining eaves 32. In this embodiment, through the insertion and abutment design of the positioning tenon 22 and the inner lining eaves 32, the initial centering and limiting of the column are achieved, significantly reducing the probability of planar misalignment and corner misalignment, providing good initial conditions for subsequent leveling operations, and further shortening the overall installation time.

[0029] like Figure 5 As shown, in one specific embodiment, the first column 2 and / or the second column 3 may further include steel columns or reinforced concrete columns. A first gap 4 exists between the ends of the first steel hoop 21 and the second steel hoop 31. After leveling by the leveling part 1, the first steel hoop 21 and the second steel hoop 31 are welded together using welding material filled in the first gap 4. The leveling part 1 is then removed after welding. When the first column 2 and / or the second column 3 also include reinforced concrete columns, the first steel hoop 21 and the second steel hoop 31 are welded to the longitudinal reinforcing bars within the reinforced concrete column, respectively. In this embodiment, the leveling part 1 is used as a temporary tooling. After leveling and welding are completed, it can be removed and reused, which not only reduces material costs but also minimizes the impact on permanent structures. This aligns with the modern engineering concept of "removable, adjustable, and repeatable" in prefabricated building construction, demonstrating high economic efficiency and promotional value.

[0030] The leveling device connected to the column is used as follows: In the factory, a first connector 11 and a second connector 12 are welded to the outer surfaces of the first column 2 and the second column 3, respectively. The first column 2 is then hoisted. After the positioning tenon 22 at the lower end of the first column 2 is inserted into the cavity of the second column 3, a first rod 13 with four nuts (first to fourth nuts 144) is inserted into the first connector 11 and the second connector 12. The first nut 141 and the fourth nut 144 are then tightened, temporarily fixing the first column 2 and the second column 3 to prevent the first column 2 from tipping over. Before tilting (leveling) the first column 2, the tilt angle is observed using instruments. Simultaneously, the tilt angle is adjusted using multiple (generally four are sufficient) second nuts 142 around the first column 2 and the second column 3. Before adjusting the second nut 142, slightly loosen the first nut 141 that has been tightened. When the inclination angle of the first column 2 is adjusted to meet the requirements of its verticality, tighten the first nut 141 again. Then weld the first gap 4 between the first column 2 and the second column 3. After welding, remove all leveling parts 1.

[0031] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
