[0023] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Please see Figure 1 and Figure 4The present invention provides a device for aligning the verticality of large steel column joints. The device comprises a lower steel column 1, an upper steel column 2, a connecting assembly, and an adjusting assembly. The upper steel column 2 is longitudinally joined to the lower steel column 1. The connecting assembly includes a lower ear plate 4, an upper ear plate 3, and a connecting plate 5. The lower ear plate 4 is welded to the upper part of the lower steel column 1, and the upper ear plate 3 is welded to the lower part of the upper steel column 2. The lower ear plate 4 and the upper ear plate 3 correspond one-to-one. The two ends of the connecting plate 5 are respectively connected to the lower ear plate 4 and the upper ear plate 3. The adjusting assembly includes a lower support member, an upper support member, and two lifting members 9. The lower end of the upper support member has two inclined surfaces, symmetrically arranged on both sides of the centerline of the upper support member. The lifting members 9 are spaced apart and installed on the upper end of the lower support member. The upper ends of the two lifting members 9 each have supporting inclined surfaces, which are respectively attached to the two inclined surfaces.

[0025] When the upper steel column 2 is placed on the lower steel column 1, the verticality of the upper steel column 2 needs to be adjusted again due to the installation process. During installation, in the process of adjusting the verticality, the inclined upper steel column is first lifted and leveled by the jacking component 9, and then the lower steel column 1 and the upper steel column 2 are positioned by the fixing connecting plate 5.

[0026] There are two lifting components 9, which are used to lift the two sides of the upper support component respectively. When vertical lifting is required, both lifting components 9 are adjusted simultaneously; when both horizontal and vertical adjustment are required, only one lifting component 9 needs to be adjusted.

[0027] The vertical alignment device for large steel column joints provided by this utility model, compared with the prior art, adds an adjustment component and uses the lifting function of the lifting component 9 to apply force to the upper support component, thereby achieving longitudinal fine adjustment of the upper steel column 2; and the support slope of the lifting component 9 and the force-bearing slope of the upper support component cooperate to achieve lateral and longitudinal fine adjustment of the upper steel column 2, thus improving the installation quality.

[0028] In some possible embodiments, please refer to Figure 1 , Figure 2 and Figure 4 The upper support includes an upper support plate 7 and an upper support block 11. The upper support plate 7 is welded to the side wall of the upper steel column 2 on the side closest to the upper steel column 2. The cross section of the upper support block 11 is an inverted isosceles triangle. The centerline of the upper support block 11 coincides with the centerline of the upper support plate 7. The lower end of the upper support block 11 forms two force-bearing inclined surfaces.

[0029] The structure of the upper support plate 7 of the upper support member is the same as that of the upper ear plate 3. The upper support plate 7 and the upper ear plate 3 are arranged in parallel and are both fixed by welding.

[0030] The length direction of the upper support plate 7 is consistent with the height direction of the upper steel column 2. One edge of the upper support plate 7 along its length direction is welded to the outer wall of the upper steel column 2, and the lower edge of the upper support plate 7 is fixed to the upper support block 11. The upper support block 11 is not fixedly connected to the upper steel column 2 to reduce the welding area of ​​the upper steel column 2, thereby reducing its welding stress and deformation. When under stress, the force on the upper support block 11 is only transmitted to the upper support plate 7, and then to the upper steel column 2 through the upper support plate 7.

[0031] The upper support plate 7 and the upper support block 11 are first prefabricated and welded to form an upper support component. Then, the upper support plate 7 part of the upper support component is attached to the side wall of the upper steel column 2 and welded to fix it.

[0032] The extension length of the upper support member in the direction perpendicular to the upper steel column 2 is greater than or equal to the extension length of the upper support block 11 in that direction. After installation, ensure that the lower end face of the upper support member is above the lower end face of the upper steel column 2 to avoid it contacting the lower steel column 1 and affecting the adjustment effect.

[0033] In some possible embodiments, please refer to Figure 1 , Figures 3 to 4 The lower support includes a lower support plate 6 and a lower support block 8. The lower support plate 6 is longitudinally welded to the side wall of the lower section steel column 1. The lower support block 8 is located at the upper end of the lower support plate 6. The upper end of the lower support block 8 has a horizontal mounting surface, which is used to install two lifting components 9.

[0034] The lower support plate 6 and the upper support plate 7 are longitudinally corresponding one-to-one. The structure of the lower support plate 6 is the same as that of the lower ear plate 4. The lower support plate 6 and the lower ear plate 4 are arranged in parallel and are both welded to the outer wall of the lower steel column 1.

[0035] The upper surface of the lower support plate 6 has a small cross-section, making it impossible to fix the lifting component 9. Therefore, a lower support block 8 is installed on the lower support plate 6. The lower part of the lower support block 8 is fixedly connected to the lower support plate 6, and the upper surface of the lower support block 8 forms a horizontal mounting surface. The area of ​​the horizontal mounting surface is larger than the longitudinal projected area of ​​the upper support block 11.

[0036] Specifically, the lower support block 8 includes a horizontal plate 13 and two longitudinal side plates 12. The horizontal plate 13 overlaps the upper end surface of the lower support member, and the upper end surface of the horizontal plate 13 forms a horizontal mounting surface. The two longitudinal side plates 12 are located on the lower end surface of the horizontal plate 13, and the two longitudinal side plates 12 are spaced apart. The two longitudinal side plates 12 are respectively attached to both sides of the lower support plate 6 and are fixedly connected to the lower support plate 6.

[0037] The horizontal plate 13 and the two longitudinal side plates 12 cooperate to form a π-shaped structure. The horizontal plate 13 overlaps the upper end of the lower support plate 6, while the two longitudinal side plates 12 connected to the lower end of the horizontal plate 13 are respectively attached to the two sides of the lower support plate 6. The longitudinal side plates 12 are parallel to the lower support plate 6, and the longitudinal side plates 12 and the lower support plate 6 are welded or bolted together.

[0038] One end of the horizontal plate 13 along its length is attached to the outer wall of the lower steel column 1, and the other end of the horizontal plate 13 along its length extends to the edge of the free end of the lower support plate 6.

[0039] Two lifting components 9 are installed at intervals on the upper end face of the horizontal plate 13. The lifting component 9 includes a lifting structure, which can be a telescopic structure such as a hydraulic rod or a cylinder.

[0040] The two longitudinal plates are fixedly connected to the lower support plate 6 by bolts. Both the longitudinal plates and the lower support plate 6 have horizontal through holes. Bolts are passed through the three through holes in sequence, and nuts are used to fix the longitudinal plates and the lower support plate 6 together.

[0041] In some possible embodiments, please refer to Figure 1 and Figure 4 The movable end of the lifting component 9 has a wedge 10, the cross section of which is triangular or trapezoidal, and the inclined surface of which is a supporting inclined surface.

[0042] Since the cross-section of the upper support block 11 is an inverted isosceles triangle, and the centerline of the upper support block 11 coincides with the centerline of the upper support plate 7, the height of the two force-bearing inclined surfaces at the lower end of the upper support block 11 gradually increases from the middle to both sides. The upper end face of the wedge block 10 at the upper end of the lifting member 9 forms a supporting inclined surface to fit against the force-bearing inclined surface and support the upper support block 11.

[0043] The lower end face of the wedge 10 of the lifting component 9 is a horizontal plane, and the lower end face of the wedge 10 is used to connect the lifting structure; the upper end face of the wedge 10 forms a supporting inclined surface. The longitudinal section of the wedge 10 is a right triangle or a right trapezoid, and the hypotenuse of the right triangle or the hypotenuse of the right trapezoid faces the force-bearing inclined surface of the upper support block 11.

[0044] Optionally, the angle between the inclined plane and the horizontal plane can be 30°-60°.

[0045] Optionally, the longitudinal section of the wedge 10 is a right trapezoid. The top edge of the right trapezoid corresponds to the upper end face of the wedge 10, which is located on one side of the upper support block 11. The bottom edge of the right trapezoid corresponds to the lower end face of the wedge 10, which is used to connect the lifting structure. The height of the right trapezoid corresponds to one longitudinal end face of the wedge 10, which is located on the side away from the upper support block 11. The hypotenuse of the right trapezoid corresponds to the supporting inclined surface of the wedge 10, which is used to fit the force-bearing inclined surface of the upper support block 11.

[0046] The two wedges 10 have identical structures and are symmetrically arranged along the axial direction of the upper support member. The two wedges 10 are symmetrically arranged, and the supporting inclined surfaces of the two wedges 10 respectively abut against the two force-bearing inclined surfaces of the upper support block 11.

[0047] When the two lifting components 9 rise simultaneously, the two wedges 10 adhere to the two force-bearing inclined surfaces of the upper support block 11 and drive the upper support block 11 and the upper support plate 7 to rise, thereby driving one side of the upper steel column 2 connected to the upper support plate 7 to rise upward.

[0048] When the upper steel column 2 is tilted, or when it needs to be lifted on one side, only one of the lifting parts 9 needs to be adjusted. When the upper support block 11 receives force from the wedge block 10 on one side, it will rotate horizontally to one side or be lifted to one side.

[0049] Since the upper steel column 2 is equipped with adjustment components on all four sides, if it is necessary to rotate the upper steel column 2 clockwise or counterclockwise, only the lifting component 9 on the same side of each adjustment component needs to be adjusted. For example, raising the right-side lifting component 9 in each adjustment component will allow the upper steel column 2 to move clockwise. The rotation direction of the upper steel column 2 is the rotation direction seen from a top-down view.

[0050] When only one side needs to be raised, only the single lifting component 9 needs to be adjusted. Synchronous adjustment of all adjustment components is not required.

[0051] In some possible embodiments, please refer to Figure 1 and Figure 4 The lower steel column 1 and the upper steel column 2 are connected to form the steel column body; the same side of the steel column body has a connecting component and two adjusting components, the two adjusting components are located on both sides of the connecting component and are spaced apart from the connecting component; or the same side of the steel column body has two connecting components and one adjusting component, the two connecting components are located on both sides of the adjusting component and are spaced apart from the adjusting component.

[0052] In the first embodiment, each side of the steel column body formed by the lower steel column 1 and the upper steel column 2 has a connecting component and two adjusting components. Taking one side of the steel column body as an example, the side of the steel column body is hereinafter referred to as the working surface. The connecting component is located on the centerline of the working surface, and the two adjusting components are symmetrically arranged along the centerline of the working surface. The distance between the adjusting component and the connecting component is equal to or greater than the distance between the adjusting component and the edge of the working surface it is close to.

[0053] In the second embodiment, each side of the steel column body has an adjusting component and two connecting components. Taking one side of the steel column body as an example, the side of the steel column body is hereinafter referred to as the working surface. The centerline of the adjusting component coincides with the centerline of the working surface. The two connecting components are symmetrically arranged along the centerline of the working surface, and the distance between the connecting component and the adjusting component is equal to or greater than the distance between the connecting component and the edge of the working surface it is close to.

[0054] In the third embodiment, the four sides of the steel column body are divided into two first working surfaces and two second working surfaces, and the two first working surfaces are symmetrical. The connecting components and adjusting components are alternately arranged along the circumference of the steel column body, that is, there is one connecting component and two adjusting components in the first working surface, and one adjusting component and two connecting components in the second working surface. Since the first working surface and the second working surface are adjacent, the connecting components and adjusting components are alternately arranged.

[0055] Pre-install upper ear plates 3 and upper support components on the upper steel column 2, and pre-fabricate lower ear plates 4 and lower support plates 6 on the lower steel column 1. After the upper steel column 2 is hoisted, first install the connecting plate 5. Keep the bolts connecting the connecting plate 5 to the upper ear plates 3 and lower ear plates 4 loose, and ensure that the diameter of the bolt holes in the connecting plate 5 is larger than the diameter of the bolt holes on the upper ear plates 3 and lower ear plates 4. Then install the lifting component 9 and drive it to adjust the upper steel column 2. Finally, tighten the bolts on the connecting plate 5 and weld it at the interface between the lower steel column 1 and the upper steel column 2. When adjusting the lifting component 9, instruments such as a laser leveling instrument can be used.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
