[0002] Steel structures are a very common building support structure. They are assembled from steel materials and have advantages such as good plasticity and toughness, excellent seismic performance, and can be recycled and reused. They are pollution-free and meet the requirements of green building. The components of steel structures are usually manufactured in factories and then transported to the site for installation, which makes the construction speed fast.

[0003] As disclosed in announcement number CN207160240U, a modular prefabricated multi-story steel structure beam-column connection node is used, including an upper steel pipe column, a lower steel pipe column, a column base and a steel beam. The structural components of the connection node of this utility model are all prefabricated in the factory and assembled on site by high-strength bolts. The construction speed is fast and it is environmentally friendly. At the same time, the steel beam structure adopts a truss steel beam structure, which is easy to cut and weld, and it is easier for equipment pipelines to pass through. It is suitable for modular prefabricated multi-story buildings and has broad application prospects.

[0004] However, in the existing technology, the positioning of the two steel pipe columns between the upper and lower parts requires moving and adjusting the steel pipe columns during the installation process, which is inconvenient. Moreover, the lateral support is only two diagonal bars, and the overall support force is not uniform enough, and the support effect needs to be improved. For example, the comparative patents listed above have this problem.

[0005] To address these issues, we propose a multi-story modular prefabricated steel structure quick-connect frame. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-story modular prefabricated steel structure quick connection frame, including vertical steel pipes and steel crossbeams set on the outside of the joint of two vertical steel pipe units, wherein a side plate is welded to the left side of the steel crossbeams;

[0008] Also includes:

[0009] An installation sleeve that serves both positioning and support functions and is positioned between the upper and lower vertical steel pipe units;

[0010] A limiting component is provided between the side plate and the mounting sleeve. The limiting mechanism causes the side plate and the mounting sleeve to form a disassembly structure.

[0011] Multiple load-bearing mechanisms are set between the individual steel beams at the upper and lower ends for auxiliary support.

[0012] Preferably, the vertical steel pipe is inserted into the mounting sleeve, and the vertical steel pipe and the mounting sleeve are limited by fastening bolts passing through the front and rear ends of the mounting sleeve.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-7 The present invention provides the following technical solution.

[0035] To address the problems in existing technologies where positioning between upper and lower steel pipe columns during installation requires moving and adjusting the columns, which is inconvenient, and where lateral support consists of only two diagonal bars resulting in uneven overall support and insufficient support effectiveness, the following technical solution is proposed: a multi-story modular prefabricated steel structure quick-connect frame. This frame includes vertical steel pipes 1 and steel crossbeams 2 positioned on the outer side of the joint between the upper and lower vertical steel pipes 1. Side plates 3 are welded to the left side of the steel crossbeams 2, providing positioning and support functions, and are positioned between the upper and lower vertical steel pipes 1. The mounting sleeve 4 between the vertical steel pipe 1 units and the limiting component are set between the side plate 3 and the mounting sleeve 4. The limiting mechanism drives the side plate 3 and the mounting sleeve 4 to form a disassembly structure. Multiple bearing mechanisms 11 are set between the steel beam 2 units at the upper and lower ends and are used for auxiliary support. The limiting component is composed of a protrusion 6, a connecting plate 7, a support plate 8, a connecting rod 9 and a connecting cap 10. Moreover, the bearing mechanism 11 is composed of a bearing plate 12 symmetrically arranged at the front and rear ends of the steel beam 2, a bearing rod 13 for connection and a fixing cap 14 with locking and limiting function.

[0036] like Figure 1 and Figure 2 As shown, firstly, the mounting sleeve 4 is placed on the upper end of the lower vertical steel pipe 1, and then the lower end of the upper vertical steel pipe 1 is inserted into the mounting sleeve 4. The upper end of the mounting sleeve 4 allows for very quick and easy docking and positioning of the upper and lower vertical steel pipes 1. After positioning, the mounting sleeve 4 and the vertical steel pipe 1 are limited by fastening bolts 5 that penetrate the front and rear ends of the mounting sleeve 4. Then, the steel crossbeam 2 drives the side plate 3 to adhere to the side of the mounting sleeve 4, as shown. Figure 3 , Figure 4 and Figure 5As shown, at this time, the connecting rod 9 is inserted into the middle of the side plate 3. Then, the connecting plate 7 and the support plate 8 are inserted between the upper and lower ends of the steel beam 2. Then, the connecting plate 7 is rotated so that the connecting rod 9 is inserted into the middle of the connecting plate 7. At the same time, the protrusion 6 is inserted into the upper and lower ends of the support plate 8. Then, the double connecting cap 10 connected to the outer surface of the connecting rod 9 is rotated. At the same time, the left connecting cap 10 is fitted with the connecting plate 7, and the double connecting caps 10 are fitted with each other, which facilitates the limitation between the side plate 3 and the mounting sleeve 4, so that the steel beam 2 and the vertical steel pipe 1 can be installed and positioned.

[0037] After the steel crossbeam 2 and the vertical steel pipe 1 are connected, and in conjunction with the setting of the load-bearing mechanism 11, such as Figure 1 , Figure 6 and Figure 7 As shown, the bearing plates 12 are respectively snapped onto the front and rear ends of the steel beam 2. Then, the bearing rod 13 is inserted into the middle of the bearing plate 12. Next, the fixing cap 14 threaded onto the outer surface of the bearing rod 13 is rotated so that the fixing cap 14 and the bearing plate 12 are fitted together, which facilitates the limiting of the bearing plate 12 and the steel beam 2. The bearing mechanism 11 facilitates the auxiliary support between the upper and lower ends of the steel beam 2. At the same time, the number and position of the bearing mechanism 11 can be adjusted to better support the steel beam 2, and the overall stability is good.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
