Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a tower crane attachment clamp suitable for the construction of small cross-section steel columns. Background Technology

[0002] Steel structures are being used more and more widely in building construction, and tower cranes are the most commonly used construction lifting machinery for hoisting steel structures.

[0003] A search revealed Chinese patent CN208182462U, which discloses a steel column hoisting clamp. The clamp consists of two separate U-shaped components with identical opening sizes. Lifting lugs are located on both sides of the opening, and these lugs have bolt holes and various hoisting holes of different sizes matching the hoisting steel rope. In operation, the lugs form a closed frame through the bolt holes. This invention has a simple structure, effectively prevents primer peeling caused by friction between the steel rope and the steel column, is suitable for various steel rope diameters, is not limited by hoisting method, and does not require removal of the lifting lugs after hoisting.

[0004] Based on the above search results combined with existing technologies;

[0005] Although the above-mentioned patents do not restrict the hoisting method, during the construction process, when the tower crane is attached and lifted, it is often encountered that the cross-section of the steel column is too small to match the attachment and lifting of the tower crane. In addition, the ear plate and the steel column cannot be directly welded on site, so there are certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a tower crane attachment clamp suitable for the construction of small-section steel columns. It is reusable, saves costs, and is convenient to construct.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a tower crane attachment clamp suitable for the construction of small cross-section steel columns, including a pair of side plates, a front plate is fixedly installed at the bottom of the pair of side plates, a back plate is fixedly installed at the top of the pair of side plates, a rear plate reinforcement is fixedly installed on the surface of the back plate, and multiple inclined plate reinforcements are fixedly installed between the side plates, the front plate, and the back plate.

[0008] Preferably, threaded holes one and two are respectively provided on the inner sides of the front plate, rear plate rib and back plate.

[0009] Preferably, both the first threaded hole and the second threaded hole are threaded with high-strength bolts.

[0010] Preferably, one end of the high-strength bolt is threaded through the front plate and fitted with a pair of nuts, and the other end of the high-strength bolt is threaded through the rear plate and fitted with a pair of nuts.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, this utility model utilizes steel reinforcement materials, such as side plates and back plates, and installs multiple inclined reinforcement bars. While ensuring that the components are easy for workers to install, it also guarantees the stability and firmness of the components, thereby improving construction efficiency and construction quality.

[0013] Secondly, this utility model facilitates a tight connection between components by installing high-strength bolts, and the installation of detachable bolts allows for the recycling of components, saving material costs and making it more economical.

[0014] This solves the problem that often occurs during the existing construction process when the tower crane is attached and lifted, and the steel column cross-section is too small to match the tower crane's attachment and lifting, and the ear plate and steel column cannot be directly welded on site.

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved tower crane attachment clamp suitable for the construction of small-section steel columns. The technical solution of this utility model is as follows:

[0022] like Figures 1-2As shown, a tower crane attachment clamp suitable for the construction of small cross-section steel columns includes a pair of side plates 1. A front plate 2 is fixedly installed at the bottom of the pair of side plates 1, and a back plate 4 is fixedly installed at the top of the pair of side plates 1. A rear plate reinforcement 3 is fixedly installed on the surface of the back plate 4. Multiple inclined plate reinforcements 8 are fixedly installed between the side plates 1, the front plate 2, and the back plate 4. Welding multiple steel reinforcement materials helps to improve the load-bearing capacity and working quality of the clamp. Moreover, the device is simple and easy to operate, which facilitates construction by workers and saves labor costs.

[0023] Furthermore, threaded holes 9 and 10 are respectively provided on the inner sides of the front plate 2, the rear plate rib 3 and the back plate 4, which facilitates the precise installation of bolts.

[0024] Furthermore, both the first threaded hole 9 and the second threaded hole 10 are threaded with high-strength bolts 5. The high-strength bolts 5 improve the structural robustness of the device, facilitate the tight connection between the clamping components, and prevent the device from loosening.

[0025] Furthermore, one end of the high-strength bolt 5 is threaded through the front plate 2 and a pair of nuts 6 are installed thereon, and the other end of the high-strength bolt 5 is threaded through the rear plate reinforcement 3 and a pair of nuts 7 are installed thereon. Installing multiple nuts facilitates the disassembly and reinforcement of the clamping device during construction, which not only ensures the stable operation of the device but also improves the flexibility and practicality of the components.

[0026] The specific working method is as follows: First, prepare a pair of side plates 1, made of steel bars. Place the side plates 1 on both sides of the steel column so that the entire device is installed around the steel column. Weld the side plates 1 to the front plate 2 to ensure that the weld is firm. Then, weld the back plate 4 to the top of the side plates 1. Both the back plate 4 and the front plate 2 are made of steel bars. Install the rear plate reinforcement 3 on the surface of the back plate 4. Determine the opening position and pass through the front plate 2, the back plate 4 and the rear plate reinforcement 3. Next, install high-strength bolts 5 inside the threaded holes. The high-strength bolts 5 pass through the rear plate reinforcement 3 and the front plate 2. At the same time, install multiple nuts. In addition, install multiple inclined plate reinforcements 8 between the side plates 1 and the front plate 2 and the back plate 4 to improve the strength and stability of the device.
