Description

Technical Field

[0001] The present invention belongs to the technical field of building steel structure installation, and particularly relates to an installation positioning device for box columns. Background Art

[0002] In building steel structure projects, box columns are widely used as important vertical load-bearing members. With the continuous increase of building height and structural complexity, the requirements for the installation accuracy and efficiency of box columns are also increasing day by day.

[0003] At present, during the installation of box columns, there are many difficulties in the butt joint installation of upper and lower box columns. The traditional installation method mainly relies on manual experience and conventional measuring tools for positioning. It is difficult to accurately control the position of the upper box column during the operation, resulting in difficult alignment of bolt holes. Often, repeated adjustments are required, consuming a large amount of time and labor costs, and seriously affecting the construction progress. At the same time, due to the lack of an effective positioning auxiliary device, the box column is prone to deviation during the butt joint process, affecting the overall stability and safety of the structure, and may cause surface damage to the column due to multiple adjustments, reducing the durability of the structure. Summary of the Invention

[0004] The purpose of the present invention is to provide an installation positioning device for box columns, aiming to solve the problems of inaccurate positioning, low installation efficiency, and difficult guarantee of structural stability during the installation of existing box columns in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An installation positioning device for box columns, comprising:

[0007] An internal butt joint wedge-shaped positioning sleeve, which is arranged at the top of the lower box steel column. The internal butt joint wedge-shaped positioning sleeve is adapted to the bottom of the upper box steel column and has a taper. Through holes matching the bolt holes of the box steel column are provided on the wall surface.

[0008] A column head through partition, which is connected to the inner wall of the box steel column at a position near the top inside the lower box steel column.

[0009] As a preferred solution of the present invention, the internal butt joint wedge-shaped positioning sleeve is stably supported by the column head through partition and maintains a horizontal position.

[0010] As a preferred solution of the present invention, bolts are arranged in the through holes of the internal butt joint wedge-shaped positioning sleeve and the bolt holes of the lower box steel column.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In this solution, the built-in docking wedge-shaped positioning sleeve is designed to be adapted to the bottom of the upper box-shaped steel column and have a taper. When hoisting the upper box-shaped steel column, it can guide it to be accurately sleeved in, reducing the positioning difficulty and docking deviation, enabling the upper and lower box-shaped steel columns to quickly approach the correct position during the initial docking;

[0013] The through holes on the wall surface of the positioning sleeve that match the bolt holes can ensure that the bolt holes of the upper box-shaped steel column and the bolt holes of the lower box-shaped steel column are accurately aligned along the trajectory of the through holes, providing an accurate basis for subsequent installation and improving the overall positioning accuracy.

[0014] 2. In this solution, with the help of the positioning sleeve and the through holes, the upper box-shaped steel column can be quickly sleeved in and the bolt holes can be aligned, and the built-in one-way self-locking bolts can be quickly inserted to complete the initial fixation, greatly shortening the installation time and reducing the time cost of manual repeated adjustment;

[0015] The precise positioning and rapid initial fixation make the subsequent calibration work more convenient and efficient, improving the fluency of the entire installation process, effectively enhancing the installation efficiency of the box-shaped column, and meeting the requirements of rapid construction of modern buildings.

[0016] 3. In this solution, the column head through diaphragm strengthens the local structural strength of the top of the lower box-shaped steel column, disperses the concentrated stress at the column top during the docking and load-bearing of the upper and lower box-shaped steel columns, prevents the deformation and damage of the column top, and ensures the overall structural stability;

[0017] The column head through diaphragm stably supports the positioning sleeve, ensuring its stability during the installation process, preventing its displacement or inclination, ensuring the effective play of the positioning and guiding function, thereby indirectly improving the installation accuracy of the box-shaped column, enabling the structure to more stably bear the load after installation, and enhancing the structural stability and reliability; at the same time, reducing the impact of column damage during the installation process on the structural durability, and ensuring the structural stability from the perspective of long-term use.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figures 1-4 , the present invention provides the following technical solutions:

[0027] An installation and positioning device for a box-shaped column, comprising:

[0028] A built-in butt joint wedge-shaped positioning sleeve 4, which is arranged at the top of the lower box-shaped steel column 2. The built-in butt joint wedge-shaped positioning sleeve 4 is adapted to the bottom of the upper box-shaped steel column 1 and has a taper. Through holes matching the bolt holes of the box-shaped steel column are opened on the wall surface;

[0029] A column head through partition 3, which is connected to the inner wall of the box-shaped steel column near the top inside the lower box-shaped steel column 2.

[0030] In a specific embodiment of the present invention, the unique structural design of the built-in butt joint wedge-shaped positioning sleeve 4, which is adapted to the bottom of the upper box-shaped steel column 1 and has a taper, plays a key guiding role during the hoisting operation of the upper box-shaped steel column 1. When the upper box-shaped steel column 1 is slowly lowered, it can be conveniently and accurately sleeved into it along the taper of the built-in butt joint wedge-shaped positioning sleeve 4. This ingenious design greatly reduces the positioning difficulty during the docking process of the upper box-shaped steel column 1 and the lower box-shaped steel column 2, effectively reducing the docking deviation caused by manual operation errors or other external factors. It enables the upper and lower box-shaped steel columns 1 and 2 to quickly approach the ideal correct relative position at the initial docking stage, laying a good foundation for subsequent precise installation and adjustment;

[0031] Another important function of the built-in docking wedge positioning sleeve 4 is reflected in the through holes carefully opened on its wall surface, which are matched with the bolt holes of the box-shaped steel column. During the sleeving process, these through holes are like precise tracks, enabling the bolt holes of the upper box-shaped steel column 1 and the bolt holes of the lower box-shaped steel column 2 to gradually achieve precise alignment along the trajectory of the through holes. This effectively avoids the subsequent dilemma that the built-in one-way self-locking bolt 5 cannot be smoothly inserted due to the misalignment of the bolt holes, significantly improving the smoothness and efficiency of the installation process. Once the bolt holes are successfully aligned, the built-in one-way self-locking bolt 5 can be quickly inserted to complete the preliminary fixing operation, greatly shortening the overall installation time. At the same time, it also provides a stable and reliable connection foundation guarantee for the precise alignment work of the upper box-shaped steel column 1 in the subsequent process;

[0032] The position of the column head through diaphragm 3 is inside the lower box-shaped steel column 2 near the column top and is closely connected to the inner wall of the box-shaped steel column. In the entire box-column structure system, this component undertakes extremely important structural strengthening tasks. Especially during the docking of the upper and lower box-shaped steel columns 1 and 2 and the subsequent process of the entire structure bearing various loads, the column top part is often a key area where stress is relatively concentrated. The column head through diaphragm 3 can effectively disperse these concentrated stresses, preventing the column top from deforming, being damaged, etc. due to excessive local stress, thus effectively ensuring the stability and safety of the entire box-column structure during use;

[0033] The column head through diaphragm 3 provides an indispensable stable and reliable support foundation for the built-in docking wedge positioning sleeve 4. Given that the built-in docking wedge positioning sleeve 4 plays a decisive key role in the installation accuracy of the upper and lower box-shaped steel columns 1 and 2, its own stability during the installation process is particularly important. The column head through diaphragm 3 can ensure that the built-in docking wedge positioning sleeve 4 always maintains an accurate horizontal position and a fixed spatial attitude throughout the installation process. It effectively prevents the built-in docking wedge positioning sleeve 4 from shifting or tilting due to external force interference, possible slight deformation of the lower box-shaped steel column 2 itself, etc., thus effectively ensuring that the positioning and guiding function of the built-in docking wedge positioning sleeve 4 can continuously and stably play its role, indirectly significantly improving the accuracy and quality level of the entire box-column installation operation.

[0034] Specifically, please refer to Figures 1-4 , the built-in docking wedge positioning sleeve 4 is stably supported by the column head through diaphragm 3 and maintains a horizontal position.

[0035] In this embodiment: When fabricating the lower box-shaped steel column 2, the column head through partition 3 is precisely welded at a predetermined position near the column top inside the lower box-shaped steel column 2. Its welding process must strictly follow relevant steel structure welding standards to ensure the weld quality between the column head through partition 3 and the inner wall of the box-shaped steel column, making their connection firm and reliable without defects such as deformation and cracking. Then, the built-in docking wedge-shaped positioning sleeve 4 is installed on the column head through partition 3. During installation, the level of the built-in docking wedge-shaped positioning sleeve 4 is precisely adjusted using measuring tools such as a level to meet the design requirements. In this way, during the subsequent hoisting operation of the upper box-shaped steel column 1, the built-in docking wedge-shaped positioning sleeve 4 can always receive the insertion operation of the upper box-shaped steel column 1 in a stable and horizontal posture, providing an accurate positioning reference for the upper box-shaped steel column 1, effectively avoiding the docking deviation problem of the upper box-shaped steel column 1 caused by the position deviation or inclination of the positioning sleeve, and thus greatly improving the accuracy and efficiency of the docking installation of the upper and lower box-shaped steel columns 1 and 2.

[0036] For details, please refer to Figures 1-3 , bolts 5 are provided in the through holes of the built-in docking wedge-shaped positioning sleeve 4 and the bolt holes of the lower box-shaped steel column 2.

[0037] In this embodiment: After the built-in docking wedge-shaped positioning sleeve 4 is installed on the column head through partition 3 and its horizontal position is adjusted, it is necessary to ensure that the through holes of the built-in docking wedge-shaped positioning sleeve 4 are precisely aligned with the bolt holes of the lower box-shaped steel column 2. The alignment accuracy needs to be controlled within a very small tolerance range. This process can be repeatedly verified with the help of professional measuring instruments such as calipers and positioning templates. When the upper box-shaped steel column 1 is inserted into the built-in docking wedge-shaped positioning sleeve 4 during the hoisting process, due to the above-mentioned precise hole alignment design, the bolt 5 can smoothly pass through the through holes of the built-in docking wedge-shaped positioning sleeve 4 and the bolt holes of the upper and lower box-shaped steel columns 1 and 2 to achieve preliminary connection and fixation. Although the bolt 5 only plays a preliminary fixing role at this time, it effectively restricts the relative displacement of the upper box-shaped steel column 1 and the lower box-shaped steel column 2 in the horizontal direction and to a certain extent in the vertical direction, providing a stable constraint condition for the subsequent precise correction of the upper box-shaped steel column 1. During the correction process, even if the upper box-shaped steel column 1 has a slight displacement trend under the action of external forces, the bolt 5 can maintain the relative position relationship between the upper and lower box-shaped steel columns 1 and 2, preventing it from deviating excessively, thus ensuring that the correction work can be carried out on a relatively stable basis, further improving the coordination of each link in the entire box-shaped column installation process and the reliability of the installation quality.

[0038] The working principle and usage process of the present invention: After the installation of the lower box-shaped steel column 2 and the steel beam is completed, the hoisting operation of the upper steel column begins.

[0039] First, insert the upper box-type steel column 1 into the built-in butt wedge-shaped positioning sleeve 4 located at the top of the column. During this process, ensure that the bolt holes of the built-in butt wedge-shaped positioning sleeve 4 and the upper box-type steel column 1 of the box-type steel column can be accurately aligned.

[0040] Next, the built-in one-way self-locking bolt 5 is inserted into the aligned bolt hole. Subsequently, the upper box-shaped steel column 1 of the box-shaped steel column is calibrated, and after the calibration is completed and the position is accurate, the inserted built-in one-way self-locking bolt 5 is tightened.

[0041] Finally, when the built-in one-way self-locking bolts 5 are tightened and all installation indicators meet the requirements, the lifting device can be removed, and the lifting work of the entire upper box-shaped steel column 1 is successfully completed. In this process, the column head through the partition 3 also plays a corresponding auxiliary or connecting role to ensure the stability and continuity of the entire structural installation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
