Description

Technical Field

[0001] The utility model belongs to the field of construction equipment, and particularly relates to a leveling device for the column foot of a stiffened column that can penetrate steel bars. Background Art

[0002] A stiffened column is a commonly used structural member in building construction, mainly used to enhance the seismic resistance and load-bearing capacity of a building. It is usually made of steel, with high strength and good ductility. The stiffened column can be used in combination with concrete to form a reinforced concrete structure, thereby improving the overall stability and safety of the building. Such columns are particularly common in high-rise buildings and structures that need to bear large loads. By using stiffened columns, various forces acting on the building can be effectively dispersed and transmitted, reducing the risk of structural deformation and damage.

[0003] During the construction process of a stiffened column, the installation of the first section of the steel column requires adjusting its elevation and verticality. Since there are steel bars outside the stiffened column, the conventional adjustment method usually requires bending the steel bars before adjusting the steel column. This method not only affects the construction quality of the steel bars, but also takes a long time and has low construction efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and provide a leveling device for the column foot of a stiffened column that can penetrate steel bars.

[0025] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the present utility model can be combined correspondingly without conflict.

[0026] As Figure 1 and Figure 2 shown, as a preferred embodiment of the specific embodiment of the present utility model, this embodiment provides a leveling device for a rigid column footing that can penetrate steel bars. The leveling device is used to adjust the first steel column 4 on the concrete floor 5, and includes an adjustment device 1 and a lifting device 2.

[0027] As Figure 3As shown in the figure, in the device provided by the present utility model, the adjusting device 1 includes a fixing structure 1-1, a limiting structure 1-3 and a plurality of adjusting structures 1-2 with the same structure. In this embodiment, two adjusting structures 1-2 are adopted. Each adjusting structure 1-2 is in a Z shape, including a lower wing plate 1-21, an upper wing plate 1-22 that are parallel to each other, and a web plate 1-23 perpendicular between the lower wing plate 1-21 and the upper wing plate 1-22, and the extending directions of the lower wing plate 1-21 and the upper wing plate 1-22 are opposite.

[0028] In this embodiment, the lower wing plate 1-21, the upper wing plate 1-22 and the web plate 1-23 in the adjusting structure 1-2 are all made of steel plates and are fixed as a whole by welding. Those skilled in the art can also select other suitable materials as the adjusting structure 1-2 according to the actual situation.

[0029] In the device provided by the present utility model, a through-hole with a certain length is opened on the web plate 1-23 of the adjusting structure 1-2, and the through-hole is opened along the length direction of the web plate 1-23. The two adjusting structures 1-2 are arranged in parallel at intervals and are connected into a whole through the fixing structure 1-1.

[0030] In the device provided by the present utility model, the fixing structure 1-1 includes a web plate part and a wing plate part perpendicular to the web plate part. A connecting hole corresponding to the through-hole on the web plate 1-23 of the adjusting structure 1-2 is opened on the web plate part of the fixing structure 1-1. The web plate part of the fixing structure 1-1 covers the web plates 1-23 of the two adjusting structures 1-2, and bolts are passed through the connecting holes opened on the web plate part of the fixing structure 1-1 and the through-holes opened on the web plates 1-23 of the adjusting structures 1-2. After the two ends of the bolts are tightened with matching nuts, the fixing structure 1-1 is fixed on the web plates 1-23 of the adjusting structures 1-2. The wing plate part of the fixing structure 1-1 is perpendicular to the web plate part and is parallel to the extending direction of the lower wing plate 1-21 of the adjusting structure 1-2.

[0031] The operator can adjust the distance between the wing plate part of the fixing structure 1-1 and the lower wing plate 1-21 of the adjusting structure 1-2 according to the thickness of the bottom plate of the steel column 4. Specifically, the height position of the bolt in the through-hole on the web plate 1-23 of the adjusting structure 1-2 is adjusted, so as to adjust the distance between the wing plate part of the fixing structure 1-1 and the lower wing plate 1-21 of the adjusting structure 1-2.

[0032] Generally, there are steel bars around the periphery of the stiffened column steel column. The conventional adjustment method usually requires bending the steel bars before adjusting the steel column. In the device provided by the present utility model, the width of the lower wing plate 1-21 is smaller than the spacing of the steel bars 3 arranged around the steel column 4, so the lower wing plate 1-21 can penetrate into the gap between the steel bars 3.

[0033] In this embodiment, the lifting device 2 uses a jack. A jack is a mechanical device for lifting heavy objects. By applying force, it can lift or move heavy objects and adjust the verticality and elevation of the steel column 4. To avoid the unsafe factors caused by the displacement during the operation of the jack, a limit structure 1-3 is also provided in the present utility model.

[0034] As Figure 4 shown, in this embodiment, the limit structure 1-3 is a box body with an opening facing downwards, which can be welded into a whole by 5 steel plates. The bottom surface of the limit structure 1-3 is fixed to the lower surface of the upper wing plate 1-22 of the adjusting structure 1-2 by means of bolt connection. To improve the overall stability of the device, the bottom surface of the limit structure 1-3 needs to cover the upper wing plates 1-22 of two adjusting structures 1-2 and is bolted to each upper wing plate 1-22. The steel plates around the limit structure 1-3 extend downwards to form a square area to limit the lifting device 2. It should be noted that those skilled in the art can also adopt connection methods such as pin shafts that are convenient for disassembly and adjustment.

[0035] The above embodiments are only a preferred solution of the present utility model, but they are not intended to limit the present utility model. Those of ordinary skill in the relevant technical field can still make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all technical solutions obtained by adopting the means of equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.
