Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a steel column installation and positioning device. Background Technology

[0002] In the field of steel structure construction, steel columns (such as H-beams) are the main load-bearing components, and the accuracy and efficiency of their on-site installation directly affect the overall quality and progress of the project. Due to limitations in transportation and hoisting capabilities, steel columns in high-rise buildings need to be fabricated and transported in sections, and then connected and installed on the construction site.

[0003] Currently, the conventional process for on-site connection of steel columns is as follows: first, the lower column section is fixed, then the upper column section is hoisted and aligned with the end of the lower column section, and temporarily fixed, and finally welded. In the temporary fixing stage, the traditional approach mainly relies on manual calibration and temporary welding for fixing.

[0004] In existing technologies, alignment mainly relies on the experience and visual inspection of construction workers, which makes it difficult to accurately guarantee the verticality of the upper and lower column sections. This results in low construction efficiency, high safety risks, and the need for manual cutting after welding, which is cumbersome and inconvenient to disassemble and reassemble. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a steel column installation and positioning device that can effectively solve the problems mentioned in the background art.

[0006] The present invention adopts the following technical solution: a steel column installation and positioning device, comprising an upper positioning seat for fixing to the bottom end of the upper column section and a lower positioning seat for fixing to the top end of the lower column section. Guide wedges are provided on both sides of the upper positioning seat, and guide sleeves adapted to the guide wedges are provided on both sides of the lower positioning seat. The guide wedges are configured to be inserted into the guide sleeves during hoisting to guide the upper and lower column sections to automatically align.

[0007] The upper positioning seat includes a left frame and a right frame, and the lower positioning seat includes a left group and a right group corresponding to the left frame and the right frame.

[0008] The cross-sectional dimension of the end of the guide wedge is smaller than that of its root, forming a frustum-shaped structure.

[0009] The left and right frames are fixed together by a fixing group, and the left and right groups are fixed together by a connecting group.

[0010] The guide wedges on both sides of the upper positioning seat are provided with reinforcing ribs at the connection points with the left and right frames, respectively.

[0011] Both the fixing group and the connecting group are bolted connection structures.

[0012] The upper and lower positioning seats are symmetrically arranged with the web of the steel column as the center.

[0013] The bottom working surface of the guide wedge is an outwardly convex arc surface.

[0014] The upper and lower positioning seats are respectively provided with pads on the surfaces that contact the upper and lower column sections to increase friction. The pads are made of rubber or polyurethane.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This device uses a mechanical structure that combines a guide wedge and a guide sleeve to achieve automatic alignment of the upper and lower column sections, reduce verticality deviation, and ensure structural safety. It adopts a detachable bolt connection method, which completely avoids temporary welding and subsequent gas cutting on the base material. The modular design can adapt to steel columns of different specifications, shorten the installation time of steel columns, and speed up the overall construction progress. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a steel column installation and positioning device includes an upper positioning seat 1 for fixing to the bottom end of the upper column 3 and a lower positioning seat 2 for fixing to the top end of the lower column 4. Guide wedges 13 are provided on both sides of the upper positioning seat 1, and guide sleeves 23 adapted to the guide wedges 13 are provided on both sides of the lower positioning seat 2. The guide wedges 13 are configured to be inserted into the guide sleeves 23 during hoisting to guide the upper and lower columns to automatically align.

[0020] The upper positioning seat 1 includes a left side frame 11 and a right side frame 12, and the lower positioning seat 2 includes a left side group 21 and a right side group 22 corresponding to the left side frame 11 and the right side frame 12.

[0021] The cross-sectional dimension of the end of the guide wedge 13 is smaller than that of its root, forming a frustum-shaped structure.

[0022] The left side frame 11 and the right side frame 12 are fixed together by a fixing group 14, and the left side group 21 and the right side group 22 are fixed together by a connecting group 24.

[0023] The guide wedges 13 on both sides of the upper positioning seat 1 are provided with reinforcing ribs at the connection points with the left frame 11 and the right frame 12, respectively.

[0024] Both the fixing group 14 and the connecting group 24 are bolted connection structures.

[0025] The upper positioning seat 1 and the lower positioning seat 2 are symmetrically arranged with the web of the steel column as the center.

[0026] The bottom working surface of the guide wedge 13 is an outwardly convex arc surface.

[0027] The upper positioning seat 1 and the lower positioning seat 2 are respectively provided with pads on their contact surfaces with the upper column 3 and the lower column 4 to increase friction. The pads are made of rubber or polyurethane, or can be anti-slip patterns or serrated grooves machined on the contact surfaces.

[0028] The guide wedge 13 is integrally formed from the same metal billet as the left side frame 11 and the right side frame 12 by casting or forging. The guide sleeve 23 is integrally formed from the same metal billet as the left side group 21 and the right side group 22 by casting or forging.

[0029] The installation gap between the fixed assembly 14 and the connecting assembly 24 is controlled to reserve space for structural deformation compensation.

[0030] One embodiment of this utility model: The left side frame 11 and left side frame 12 of the upper positioning seat 1 are horizontally installed at the lower end of the required upper column 3 and locked with bolts. The left side group 21 and right side group 22 of the lower positioning seat 2 are horizontally installed at the upper end of the required lower column 4 and locked with bolts. The upper steel column 3 is hoisted so that the guide wedge 13 at its bottom is aligned with the guide sleeve 23 at the top of the lower column 4. Under the action of gravity, the guide wedge 13 will naturally insert into the guide sleeve 23. The guide wedge 13 is usually designed as a frustum structure. Even if there is a slight initial deviation, it can automatically guide the steel column to return to its position during the insertion process, which greatly reduces the difficulty of adjustment. After confirming that the verticality, elevation and axis of the steel column fully meet the design requirements, the joint interface of the upper and lower steel columns is formally welded. After the welding is completed, the weld quality is inspected according to regulations. After the welding quality is accepted, the bolts connecting the upper and lower positioning seats can be loosened and removed. The entire device can be removed from the fixed steel column, cleaned and reused at the next column position.

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