[0021] In summary, this application has the following technical effects:

[0022] This application discloses a steel beam docking device and method for docking a first steel beam and a second steel beam at their ends. The first steel beam has a first connecting end for docking, and the second steel beam has a corresponding second connecting end. The steel beam docking device includes a first connecting plate, a second connecting plate, and a hydraulic lifting assembly.

[0036] The technical solution of this embodiment will be clearly and completely described below with reference to the accompanying drawings. The embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of this application. Therefore, it should be understood that various modifications and changes can be made to this embodiment without departing from the scope of protection of this application.

[0037] In the description of this application, unless otherwise expressly specified and limited, the term "and / or" includes any and all combinations of one or more of the associated listed items. Unless otherwise specified or stated, the terms "connection," "fixed," etc., should be interpreted broadly; for example, "connection" can be a fixed connection, a detachable connection, an integral connection, an electrical connection, or a signal connection; "connection" can be a direct connection or an indirect connection via an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] Furthermore, in the description of this application, it should be understood that the directional terms described in this embodiment are described from the angles shown in the accompanying drawings and should not be construed as limiting this embodiment. It should also be understood that, in the context, when an element or feature is mentioned as being connected to another element (one or more), it can be connected not only directly to the other element (one or more), but also indirectly to the other element (one or more) through an intermediate element.

[0039] Before introducing the technical solution of this application, it is necessary to explain the background of the invention. It is a common practice in related technologies that, during the steel beam connection process, construction workers typically use simple fixing tools to secure the two steel beams to a certain extent. This makes it difficult to achieve a stable joint and mutual fixation between the two beams. During subsequent welding or bolting, the mating surfaces of the two steel beams may shift, making the connection inconvenient and affecting the quality of the steel beam connection. Furthermore, deviations in the position of the steel beam connection affect the stability of the connection, posing safety hazards and consequently impacting the construction progress.

[0040] To address the aforementioned challenges, this application provides an exemplary embodiment of a steel beam docking device. Please refer to [link to example]. Figures 1 to 3This device is used to connect the first steel beam 1 and the second steel beam 2 at their ends. The first steel beam 1 has a first connecting end 11 for docking, and the second steel beam 2 has a corresponding second connecting end 21. The steel beam docking device includes a first connecting plate 3, a second connecting plate 4, and a hydraulic lifting assembly. The first connecting plate 3 is located on the top surface of the first connecting end 11 and extends towards the docking direction. The first steel beam 1 has a positioning plate 31, a first baffle 32 perpendicular to the docking direction, and a second baffle 33 facing the docking direction. The second connecting plate 4 is located on the top surface of the second connecting end 21 and has a third baffle 41 perpendicular to the docking direction and a fourth baffle 42 parallel to the docking direction. The hydraulic lifting assembly is located on the top surface of the lower flange of the first connecting end 11, and a support plate 52 is located at the top of the hydraulic lifting assembly. The support plate 52 can abut against the bottom surface of the upper flange of both the first steel beam 1 and the second steel beam 2 via the hydraulic lifting assembly. Rotating the first locking member 6 of the third baffle 41 pushes the first baffle 32 to finely adjust the front-to-back offset of the first steel beam 1 and the second steel beam 2. Rotating the second locking member 7 of the fourth baffle 42 pushes the second baffle 33 to finely adjust the left-to-right offset of the first steel beam 1 and the second steel beam 2, thus completing the steel beam connection. In this embodiment, the third baffle 41 and the fourth baffle 42 form a T-shaped structure baffle. Of course, in some other embodiments, an L-shaped structure or a cross-shaped structure can also be formed. This application does not specifically limit this, as long as the third baffle 41 and the fourth baffle 42 are perpendicular to each other. It should be noted that the first and second locking members 7 are specifically bolt and nut structures. The third and fourth baffles 42 are provided with mounting through holes. Nuts are fixed to the outer edge of the through holes, and bolts are screwed into them. That is, rotating the first bolt of the third baffle 41 pushes the first baffle 32 to finely adjust the front-to-back offset of the first steel beam 1 and the second steel beam 2, and rotating the second bolt of the fourth baffle 42 pushes the second baffle 33 to finely adjust the left-to-right offset of the first steel beam 1 and the second steel beam 2.

[0041] Using lifting machinery, the positioning plate 31 is brought into contact with the top surface of the second connecting end 21, completing the initial steel beam docking. A hydraulic lifting device 5 is installed so that the support plate 52 abuts against the bottom surface of the upper flange of the first steel beam 1. The lifting machinery is used to adjust the first steel beam 1 and the second steel beam 2 to the same elevation. Rotating the first locking member 6 pushes the first baffle 32 to fine-tune the front-to-back offset of the first steel beam 1 and the second steel beam 2. Rotating the second locking member 7 pushes the second baffle 33 to fine-tune the left-to-right offset of the first steel beam 1 and the second steel beam 2, completing the steel beam docking. This application aims to achieve horizontal control and joint alignment during steel beam docking, effectively avoiding the problems of rudimentary docking methods, large joint alignment errors, and poor docking quality in traditional processes. Furthermore, the above-mentioned steel beam docking devices are all detachable structures, reusable, and applicable to the docking of various types of steel beams. This device uses ordinary steel and standard parts as the main materials, making it easy to manufacture and low in cost. Therefore, compared with existing steel beam docking technologies, the steel beam docking device and method provided by this invention have significant technical advantages.

[0042] In some embodiments, please refer to Figure 1 and Figure 2 The first connecting plate 3 is provided with a lifting lug 34 parallel to the docking direction. By providing this lifting lug 34, during the initial steel beam docking process, the operator can pull the steel wire rope passing through the lifting lug hole of the lifting lug 34 to allow the positioning plate 31 to smoothly overlap the top surface of the second steel beam 2 for subsequent docking work. Furthermore, as a preferred technical solution, the lifting lug 34 is connected to the first baffle 32. The connection between the lifting lug 34 and the first baffle 32 enhances the overall strength of the first connecting plate 3. Even further, based on this, several reinforcing ribs 35 are provided between the lifting lug 34 and the first connecting plate 3 to further strengthen the connection strength between the lifting lug 34 and the first connecting plate 3.

[0043] In some embodiments, the first connecting plate 3 is detachably mounted to the top surface of the first connecting end 11 by means of a first fastener (not shown), and the second connecting plate 4 is detachably mounted to the top surface of the second connecting end 21 by means of a second fastener (not shown). Using the first and second fasteners for fixing not only achieves the installation and fixation of the first and second connecting plates 4, but also allows them to be disassembled after the steel beams are joined, enabling the first and second connecting plates 4 to be reused and reducing production costs.

[0044] In some embodiments, please refer to Figure 2The third baffle 41 is provided with a first groove 411 for the first locking member 6 to slide horizontally, and the fourth baffle 42 is provided with a second groove 421 for the second locking member 7 to slide horizontally. Based on this, the steel beam docking device can be applied to various types of steel beam docking processes. For example, when there are interfering objects on the top surface of the first connecting end 11 or the top surface of the second connecting end 21, to avoid these interferences, the first connecting plate 3 or the second connecting plate 4 cannot be accurately installed, resulting in misalignment between the locking member and the baffle. Therefore, construction personnel can adjust the fixing position of the nut through the bolt groove, thereby changing the position of the bolt to avoid misalignment between the locking member and the baffle, thus enabling subsequent adjustment of the joint between the first and second steel beams 2.

[0045] In some embodiments, please refer to Figure 1 and Figure 2 The hydraulic lifting assembly includes a hydraulic lifting device 5 and a support block 51. The hydraulic lifting device 5 is installed on top of the support block 51. The bottom of the support block 51 is fixed to the top surface of the lower flange of the first connecting end 11 by a third fastener (not shown in the figure). The output end of the hydraulic lifting device 5 is provided with a lifting column, and the support plate 52 is fixed to the top of the lifting column. When the first steel beam 1 and the second steel beam 2 are initially connected, the construction personnel begin to install the hydraulic lifting assembly on the top surface of the lower flange of the first connecting end 11 of the first steel beam 1. The support block 51 is fixed to the top surface of the lower flange of the first connecting end 11 by the third fastener. The hydraulic lifting device 5 is installed on top of the support block 51 by a fourth fastener (not shown in the figure). The top of the lifting column at the output end of the hydraulic lifting device 5 is fixedly connected to the support plate 52. At this point, the installation of the hydraulic lifting assembly is completed. The hydraulic lifting device 5 is activated, causing the support plate 52 to abut against the bottom surface of the upper flange of the first steel beam 1 under the support of the lifting column. The first steel beam 1 is then adjusted using a lifting machine, with the connection point between the first steel beam 1 and the second steel beam 2 as the fulcrum, until the support plate 52 simultaneously abuts against the bottom surface of the upper flange of both the first steel beam 1 and the second steel beam 2, thus ensuring that the first and second steel beams 2 are at the same elevation. Furthermore, the hydraulic lifting assembly also includes a bubble level to ensure that the first steel beam 1 and the second steel beam 2 are at the same elevation.

[0046] An exemplary embodiment of the present invention also provides a method for connecting steel beams, comprising the following steps:

[0047] S1: Prefabricate the first connecting plate 3 and the second connecting plate 4, and fix the first connecting plate 3 to the top surface of the first connecting end 11 with the first fastener, and fix the second connecting plate 4 to the top surface of the second connecting end 21 with the second fastener;

[0048] S2: Use lifting machinery to move the first steel beam 1 above the second steel beam 2, slowly lower the first steel beam 1, and pull the wire rope passing through the lifting lug hole on the lifting lug plate 34 so that the bottom surface of the positioning plate 31 contacts the top surface of the second connecting end 21 to complete the initial steel beam docking;

[0049] S3: Install the hydraulic lifting assembly and support plate 52, turn on the hydraulic lifting device 5, and let the support plate 52 abut against the bottom surface of the upper flange of the first connecting end 11. Use lifting machinery to adjust the first steel beam 1 so that the support plate 52 abuts against the bottom surface of the upper flange of both the first steel beam 1 and the second steel beam 2 at the same time, and observe the bubble level until the first steel beam 1 and the second steel beam 2 are at the same elevation.

[0050] S4: Rotate the first locking member 6 to push the first baffle 32 to finely adjust the front-to-back offset of the first steel beam 1 and the second steel beam 2, and rotate the second locking member 7 to push the second baffle 33 to finely adjust the left-to-right offset of the first steel beam 1 and the second steel beam 2 to complete the steel beam docking.

[0051] The steel beam docking method described above not only enables horizontal control of the steel beam docking but also allows for multi-dimensional adjustment of the horizontal direction. Therefore, compared to existing steel beam docking technologies, the steel beam docking device and method provided in this application have significant technical advantages.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
