[0002] With the country's strong advocacy for green prefabricated buildings in recent years, the development of steel structure buildings has become increasingly rapid. At the same time, some common problems in steel structure construction have become more and more prominent. In particular, in steel-concrete composite structures, the width of the joint between the steel beam and the corbel at the node or the segmented extension of the steel beam on site when it is too long is difficult to adjust and control. The traditional method is to install chain hoists and manually pull to adjust it, which wastes a lot of manpower, material resources and time, and the operation effect is poor. Utility Model Content

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0031] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0033] In related technologies, when steel beams in steel-concrete composite structures are joined and assembled with corbels at joints, or when steel beams are too long and are extended in sections on site, the width of the joint is difficult to adjust and control. Traditional methods use chain hoists and manual pulling to adjust it, which wastes a lot of manpower, material resources and time, and the work results are poor.

[0034] To address certain technical issues, this application provides a steel beam hoisting docking adjustment device. Compared to manual chain hoisting, this horizontal steel beam docking width adjustment device is simpler, more convenient, and easier to operate, saving 60% on labor costs, 40% on time, and a significant amount of on-site operating space. It effectively avoids cross-operations between different professional construction teams, shortens the construction period, and ensures that the adjusted joint width is less prone to rebound. This improves the efficiency of high-altitude docking of horizontal steel beams, ensures the convenience and safety of high-altitude workers, significantly increases the first-pass perforation rate of high-strength bolts, provides precise control of weld width, and noticeably improves welding quality.

[0035] This application is described below with reference to the accompanying drawings and specific embodiments:

[0036] Combination Figures 1-4 This application provides a steel beam hoisting docking adjustment device, including a gantry steel frame 10 and a support steel plate 20. The two ends of the gantry steel frame 10 are respectively set on both sides of the steel beam docking joint, and the support steel plate 20 is set on one side of the steel beam docking joint.

[0037] A jack fixing seat 30 is fixedly connected to the inner side wall of the gantry steel frame 10. A jack 40 is provided on one side of the jack fixing seat 30. The telescopic end of the jack 40 is fixedly connected to one side of the supporting steel plate 20.

[0038] The steel beam hoisting and adjusting device consists of two steel plates (a small steel frame 10 and a supporting steel plate 20) and a hydraulic jack 40. The small steel plate is welded to the upper flange of the short beam at the joint. The large steel plate is a portal cantilever type, with one end welded to the upper flange of the long beam at the joint, and the other end crossing the small steel plate and keeping the cantilever free. The two gaps between the large and small steel plates can be used to install the hydraulic jack 40. During on-site construction, the width of the joint can be adjusted by changing the installation position of the hydraulic jack and pushing accordingly, according to the actual width of the joint.

[0039] In this embodiment, the method of using the structural horizontal steel beam butt joint width adjustment device is as follows:

[0040] 1. When hoisting the steel beam, first temporarily fix the far end of the steel beam, and weld the bracket plate to the upper flange side of the near end of the steel beam for temporary lap support;

[0041] 2. Fabricate small steel plates and large steel plate parts (gantry steel frame 10 and supporting steel plate 20) in the processing plant or on site, and weld the large and small steel plates to the upper flanges of the horizontal steel beam and steel bracket to be connected according to the design specifications.

[0042] 3. When the weld needs to be narrowed, install jack 40 in the left gap of gantry steel frame 10 and supporting steel plate 20, adjust the weld width to the design width and fix the end of the steel beam; when the weld needs to be widened, install jack 40 in the right gap of gantry steel frame 10 and supporting steel plate 20, adjust the weld width to the design width and fix the end of the steel beam.

[0043] 4. After the ends of the horizontal steel beam are fixed in place, first remove the jack 40, then cut off the large and small steel plates (gantry steel frame 10 and support steel plate 20). The large and small steel plates can be reused multiple times.

[0044] In some embodiments, the gantry steel frame 10 is a portal cantilever structure, with one end of its root welded to the upper flange of the long beam at the joint and the other end of its root welded to the upper flange of the short beam at the joint.

[0045] In some embodiments, the supporting steel plate 20 has a square plate structure and is fixedly connected to the upper flange of the long beam at the joint or the upper flange of the short beam at the joint by welding.

[0046] In some embodiments, a reinforcing plate 50 is fixedly connected to one side of the supporting steel plate 20.

[0047] In some embodiments, the gantry steel frame 10 is symmetrically provided with support components 60 on both sides. Each support component 60 includes a support plate 61; a limiting slot 62, fixedly connected to one side of the support plate 61 and engaging with one side of the steel beam; a flat mounting component 70 is provided on the outer wall of the support plate 61, including a threaded sleeve 71 fixedly connected to the outer wall of the support plate 61; a threaded rod 72 threadedly connected to the inner wall of the threaded sleeve 71; an adjusting knob 73 fixedly connected to one end of the threaded rod 72; and a rotating seat 74 rotatably connected to one end of the threaded rod 72. Rod 75 is fixedly connected to one side of rotating seat 74; mounting limit plates 76 are fixedly connected to both ends of connecting rod 75. By setting support assembly 60 and flat mounting assembly 70, when installing the docking adjustment device, firstly, the support plate 61 is fixed to both sides of the upper flange of the steel beam through the limit slot 62. Then, by rotating threaded rod 72, the threaded rod 72 drives the mounting limit plates 76 at both ends of connecting rod 75 to move, so that the mounting limit plates 76 limit both sides of the gantry steel frame before welding. This can ensure that the gantry steel frame is set flat on the steel beam and improve the docking accuracy.
