Description

Technical Field

[0001] This utility model relates to the field of steel structure assembly technology, and in particular to a rapid assembly interface for modular prefabricated steel structures. Background Technology

[0002] A rapid assembly interface for modular prefabricated steel structures is a connection device or structural form used to connect various components in a modular prefabricated steel structure to achieve rapid and efficient assembly. One type of connection between a main beam and a secondary beam has the following structure:

[0003] 1. Secondary steel beams, as secondary load-bearing components in the structural system, bear and transfer local loads;

[0004] 2. The main steel beam structure is the main load-bearing frame and must have higher strength and stability;

[0005] 3. R-shaped stiffening ribs increase local stiffness, thereby improving the load-bearing capacity of the main beam steel structure at the connection points;

[0006] 4. Bolts and nuts, as connecting components, achieve fixation between components through threaded engagement.

[0007] After the bolt passes through the pre-drilled holes on the R-shaped stiffening ribs of the secondary beam steel structure and the main beam steel structure, the bolt is in a state where it can rotate freely. During the connection between the nut and the bolt, the bolt may rotate synchronously as the nut is tightened, causing the nut to be unable to be tightened smoothly. Therefore, the construction workers need to fix the bolt while rotating the nut, which increases the operation steps, prolongs the installation time, and increases the complexity of manual operation, thereby reducing construction efficiency and thus reducing the assembly efficiency of the modular prefabricated steel structure. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a quick assembly interface for modular prefabricated steel structures. It solves the problem that during the connection process between nuts and bolts, the bolts rotate synchronously as the nuts are tightened, preventing the nuts from being properly tightened. Therefore, construction workers need to fix the bolts while rotating the nuts, increasing the operational steps, extending installation time, and increasing the complexity of manual operation, thus reducing construction efficiency and consequently lowering the assembly efficiency of modular prefabricated steel structures.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A modular prefabricated steel structure quick assembly interface includes a secondary beam steel structure. Three bolts are installed on the exterior of the secondary beam steel structure. A limiting mechanism for restricting bolt rotation is provided on the exterior of the secondary beam steel structure. The limiting mechanism includes a clamping plate, threaded holes, a screw, a limiting plate, and slots. The clamping plate is slidably connected to the exterior of the secondary beam steel structure. The threaded holes are located on the exterior of the secondary beam steel structure. The screw is threadedly connected to the interior of the threaded holes. The limiting plate is located on the exterior of the clamping plate. There are three slots, all located on the exterior of the limiting plate. The bolt end is located inside the slots and is used to restrict bolt rotation.

[0011] Preferably, a locking block is fixedly installed on the upper surface of the clamping plate, and a limiting plate is engaged with the outside of the locking block.

[0012] Preferably, a limiting frame for restricting the movement of nuts is provided on the side of the secondary beam steel structure away from the limiting plate. The limiting frame has three round holes on its outside. The limiting frame is slidably connected to the outside of the bolt through the round holes. A connecting plate is fixedly installed at the bottom of the limiting frame. The connecting plate is located inside the clamping plate to prevent the nuts from loosening due to vibration, external force, etc., and to ensure the stability of the modular prefabricated steel structure during use.

[0013] Preferably, a pressure plate is slidably connected to the inner side of the clamping plate, and a through hole is opened on the side of the clamping plate corresponding to the pressure plate. A guide plate is slidably connected inside the through hole and fixedly installed on the outside of the pressure plate.

[0014] Preferably, the screw is externally fixed with an anti-loss rope, which is fixedly connected to the outside of the clamping plate to prevent the screw from being lost during disassembly or installation.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Bolts pass through pre-drilled holes on the R-shaped stiffening ribs of the secondary and main beam steel structures, allowing them to rotate freely. The limiting plate is then connected to the bolt end via a slot. The clamping plate slides outside the secondary beam steel structure. Rotating the screw pushes the pressure plate, causing it to fit tightly against the outside of the secondary beam steel structure. Friction is used to fix the clamping plate to the secondary beam steel structure. The bolt is now restricted by the slot and cannot rotate. The operator can then tighten the nut onto the bolt thread, initially connecting the secondary and main beam steel structures. This avoids the bolt rotating when tightening the nut, improving installation efficiency and facilitating the rapid assembly of modular prefabricated steel structures.

[0017] Second, the limiting bracket is slidably connected to the outside of the bolt through a round hole, and then fixed by the connection between the connecting plate and the clamping plate, thereby preventing the nut from loosening due to vibration, external force, etc., and ensuring the stability of the modular assembled steel structure during use.

[0025] This application provides a quick assembly interface for modular prefabricated steel structures, effectively solving the problem that during the connection of nuts and bolts, the bolts rotate synchronously as the nuts are tightened, causing the nuts to be unable to be tightened smoothly. Therefore, construction workers need to fix the bolts while rotating the nuts, which increases the operation steps, prolongs the installation time, and increases the complexity of manual operation, thereby reducing construction efficiency and the assembly efficiency of modular prefabricated steel structures.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this application embodiment effectively solves the problem that during the connection process between the nut and bolt, the bolt rotates synchronously as the nut is tightened, causing the nut to be unable to be tightened smoothly. Therefore, construction workers need to fix the bolt while rotating the nut, which increases the operation steps, prolongs the installation time, and increases the complexity of manual operation, thereby reducing construction efficiency and thus reducing the assembly efficiency of modular prefabricated steel structures. The overall idea is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a quick assembly interface for a modular prefabricated steel structure, including a secondary beam steel structure 1. Three bolts 2 are installed on the outside of the secondary beam steel structure 1. A limiting mechanism for restricting the rotation of the bolts 2 is provided on the outside of the secondary beam steel structure 1. The limiting mechanism includes a clamping plate 3, a threaded hole 4, a screw 5, a limiting plate 6, and a slot 7. The clamping plate 3 is slidably connected to the outside of the secondary beam steel structure 1. The threaded hole 4 is opened on the outside of the secondary beam steel structure 1. The screw 5 is threadedly connected to the inside of the threaded hole 4. The limiting plate 6 is located on the outside of the clamping plate 3. There are three slots 7, which are opened on the outside of the limiting plate 6. The end of the bolt 2 is located inside the slot 7 and is used to restrict the rotation of the bolt 2.

[0029] The slot 7 in the limiting mechanism is connected to the end of the bolt 2 to limit the rotation of the bolt 2 during the installation of the nut, thereby facilitating the connection between the nut and the bolt 2. At the same time, through the coordinated work of components such as the clamping plate 3 and the screw 5, the limiting plate 6 is limited. The screw 5 pushes the pressure plate 12 to fit tightly against the surface of the steel structure, so that neither the limiting plate 6 nor the clamping plate 3 can move.

[0030] A clamping block 8 is fixedly installed on the upper surface of the clamping plate 3, and a limiting plate 6 is snapped onto the outside of the clamping block 8. The detachable connection of the limiting plate 6 facilitates the replacement of the limiting plate 6, so as to accommodate different numbers of bolts 2.

[0031] On the side of the secondary beam steel structure 1 away from the limiting plate 6, there is a limiting frame 9 for limiting the movement of the nut. The limiting frame 9 has three round holes 10 on its outside. The limiting frame 9 is slidably connected to the outside of the bolt 2 through the round holes 10 to prevent the nut from loosening due to vibration, external force, etc., and to ensure the stability of the modular prefabricated steel structure during use.

[0032] A connecting plate 11 is fixedly installed at the bottom of the limiting frame 9. The connecting plate 11 is located inside the clamping plate 3 and is fixed by the screw 5 clamping the connecting plate 11.

[0033] A pressure plate 12 is slidably connected to the inner side of the clamping plate 3. The pressure plate 12 can provide a large contact area, evenly distribute pressure, and ensure tightness of connection. A through hole 13 is opened on the side of the clamping plate 3 corresponding to the pressure plate 12. A guide plate 14 is slidably connected inside the through hole 13. The guide plate 14 is fixedly installed on the outside of the pressure plate 12. The through hole 13 provides a sliding channel for the guide plate 14, ensuring that the pressure plate 12 maintains linear movement during movement and avoids deviation.

[0034] The screw 5 is externally fixedly connected with an anti-loss rope 15, which is fixedly connected to the outside of the clamping plate 3 to prevent the screw 5 from being lost during disassembly or installation.

[0035] Working principle:

[0036] First, when the secondary beam steel structure 1 needs to be connected to the main beam steel structure, bolts 2 are first passed through the pre-drilled holes on both the secondary beam steel structure 1 and the main beam steel structure to initially position them. At this time, bolts 2 are in a state where they can rotate freely. Then, the limiting plate 6 is snapped onto the outside of the clamping block 8. The limiting plate 6 is then connected to the end of bolt 2 through the clamping groove 7. At this time, the clamping plate 3 slides on the outside of the secondary beam steel structure 1. Then, the screw 5 is rotated to push the pressure plate 12 so that the pressure plate 12 fits tightly against the secondary beam. On the outside of steel structure 1, pressure plate 12 is tightly attached to the outside of secondary beam steel structure 1. The clamping plate 3 is fixed to secondary beam steel structure 1 by the friction between pressure plate 12 and secondary beam steel structure 1. At this time, bolt 2 is restricted by slot 7 and cannot rotate. At this time, the operator can screw the nut into the thread of bolt 2 to initially connect secondary beam steel structure 1 with main beam steel structure. This method avoids the problem of bolt 2 rotating when tightening nut, and improves installation efficiency. At this time, secondary beam steel structure 1 and main beam steel structure are assembled.

[0037] In the second step, the screw 5 is rotated in the opposite direction to move it away from the pressure plate 12. At this time, the limiting frame 9 is slidably connected to the outside of the bolt 2 and attached to the surface of the nut. The connecting plate 11 is located inside the clamping plate 3. Then, the screw 5 is rotated again to push the pressure plate 12 so that the pressure plate 12 is tightly attached to the outside of the connecting plate 11. The connecting plate 11 is clamped and fixed. The limiting frame 9 is fixed. At this time, the clamping plate 3, the limiting frame 9 and the connecting plate 11 form a whole. The nut is restricted by the limiting frame 9 and cannot move. The final assembly of the secondary beam steel structure 1 and the main beam steel structure is completed.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
