Description

Technical Field

[0001] This utility model belongs to the field of modular prefabricated steel structure technology, and particularly relates to modular prefabricated steel structure beam-column connection components. Background Technology

[0002] Modular prefabricated steel structures break down buildings into modular units, such as prefabricated steel frames in factories, and then assemble them on-site. They have advantages such as fast construction, high quality, and good earthquake resistance. They are used in residential buildings (such as affordable housing in Xiong'an), public buildings (such as Huoshenshan Hospital), commercial buildings (long-term rental apartments), and industrial plants. They are in line with the trends of building industrialization and green and low-carbon construction. Through standardized design and reliable connection, they achieve efficient construction and flexible combination.

[0003] Currently, Chinese utility model patent CN220035689U discloses a modular prefabricated beam-column connection structure, including a first concrete column assembly, a connecting assembly, a second concrete column assembly, and a concrete beam assembly. The first, second, and third concrete column assemblies are all equipped with H-beams. The connecting assembly is located at the upper end of the first concrete column assembly and is detachably connected to it. The second concrete column assembly is detachably connected to the upper end of the connecting assembly. The concrete beam assembly is located on one side of the connecting assembly and is detachably connected to it. This design allows for rapid disassembly and assembly of the concrete beams and columns on the construction site, reducing welding and wet work, and thus improving construction efficiency.

[0004] While the aforementioned patents have solved the problem of rapid disassembly and assembly of beams and columns, some exposed installation bolts are prone to loosening after prolonged use, which increases the safety risks to the building and results in low efficiency. Utility Model Content

[0005] The purpose of this utility model is to address modular prefabricated steel structure beam-column connection components, the advantage of which is to prevent bolts from loosening.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a modular prefabricated steel structure beam-column connection assembly, including a support column, with connecting shells welded to the upper ends of both sides of the support column, a support beam detachably connected inside the connecting shell, two sets of slide rails welded to both sides of the support beam, and sliding plates slidably connected to the surfaces of the two sets of slide rails, with limit rods welded inside the sliding plates, and six sets of limit plates slidably connected to the surfaces of the limit rods.

[0007] The above technical solution is adopted as follows: When in use, the support beam is installed inside the connecting shell, the slide plate slides on the surface of the slide rail and covers the surface of the nut, and the slide plate will drive the limiting plate to limit the nut on both sides. The limiting plate will restrict the nut from rotating naturally, thereby preventing the connection between the connecting shell and the support beam from loosening. The slide plate is made of tempered glass, so the limiting plate and the nut can be observed.

[0008] The present invention is further configured such that the connecting shell and the support beam are detachably connected by three sets of connecting bolts, both ends of which are threaded with nuts, and the nuts are detachably connected to the limiting plate.

[0009] Using the above technical solution: After the connecting bolts pass through the connecting shell and the support beam, they can be fixed with nuts.

[0010] The present invention is further configured such that a baffle is slidably connected inside the skateboard, and a positioning bolt is rotatably connected inside the baffle, and the positioning bolt is threadedly connected to the support beam.

[0011] The above technical solution involves moving the baffle outwards when pushing the skateboard to prevent the nut from blocking its movement.

[0012] The present invention is further configured such that two sets of connecting plates are welded to the surface of the positioning bolt, and the connecting plates and the baffle are rotatably connected.

[0013] Using the above technical solution: rotating the positioning bolts can fix the position of the baffle and the slide plate.

[0014] The present invention is further configured such that a rotating rod is rotatably provided between the six sets of limiting plates and the sliding plate, and three pairs of positive and negative threads are provided between the rotating rod and the three pairs of limiting plates.

[0015] Using the above technical solution: when the rotating rod is rotated, the corresponding two limiting plates will move relative to or in opposite directions on the corresponding two positive and negative thread surfaces.

[0016] The present invention is further configured such that a plurality of circular plates are welded to the surface of the rotating rod, and a rotating handle is welded to one end of the rotating rod.

[0017] The above technical solution is adopted: the circular plate can prevent the limiting plate from moving out of the positive and negative thread surface, and the rotating handle can facilitate the rotation of the rotating rod.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. The limiting plate is positioned on both sides of the nut, which prevents the nut from rotating naturally and causing the support beam to loosen, thus increasing the safety of the beam and column. In addition, the sliding plate and baffle also have a certain effect on waterproofing the nut.

[0020] 2. By adjusting the spacing between the two sets of limiting plates, nuts of various specifications can be limited by the limiting plates, greatly increasing the practicality of the anti-loosening function. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1-2 , Figure 4 The modular prefabricated steel structure beam-column connection assembly includes a support column 1, with connecting shells 2 welded to the upper ends of both sides of the support column 1. A support beam 3 is detachably connected inside the connecting shell 2. Two sets of slide rails 405 are welded to both sides of the support beam 3. A sliding plate 401 is slidably connected to the surface of the two sets of slide rails 405. A limit rod 409 is welded inside the sliding plate 401. Six sets of limit plates 406 are slidably connected to the surface of the limit rod 409.

[0029] The shell 2 and the support beam 3 are detachably connected by three sets of connecting bolts 407. Both ends of the connecting bolts 407 are threaded with nuts 408, and the nuts 408 are detachably connected to the limiting plate 406.

[0030] The slide plate 401 is slidably connected to a baffle 402, and the baffle 402 is rotatably connected to a positioning bolt 404, and the positioning bolt 404 is threadedly connected to the support beam 3.

[0031] Two sets of connecting plates 403 are welded to the surface of the positioning bolt 404, and the connecting plates 403 and the baffle 402 are rotatably connected.

[0032] Brief description of usage: In use, connect the connecting bolt 407 to the corresponding connecting shell 2 and support beam 3, and tighten it with nut 408. Then push the slide plate 401 on the surface of slide rail 405. Before pushing, the baffle 402 will be moved outward to prevent the baffle 402 from being blocked by nut 408. When pushed to a certain position, rotate the positioning bolt 404. The positioning bolt 404 will be connected to the inside of support beam 3, thus fixing the position of baffle 402 and slide plate 401. When slide plate 401 moves, it will cause the corresponding two sets of limit plates 406 to be just limited on both sides of nut 408. This can prevent nut 408 from rotating naturally during use. Slide plate 401 is made of tempered glass, so you can see the limiting situation of limit plates 406 and nut 408. Slide plate 401 and baffle 402 can provide a certain waterproof effect for nut 408.

[0033] Example 2:

[0034] refer to Figure 2-3 A rotating rod 502 is provided between the six sets of limiting plates 406 and the sliding plate 401 for rotation. The rotating rod 502 and the three pairs of limiting plates 406 are provided with three pairs of positive and negative threads 504.

[0035] Several sets of circular plates 503 are welded to the surface of the rotating rod 502, and a rotating handle 501 is welded to one end of the rotating rod 502.

[0036] Brief description of usage: When dealing with various sizes of connecting bolts 407 and nuts 408, the rotating handle 501 can be rotated. The rotating handle 501 will drive the rotating rod 502 to rotate, which will cause the corresponding two sets of limiting plates 406 to move in opposite directions on the surface of the corresponding pair of positive and negative threads 504. When dealing with a larger nut 408, the two sets of limiting plates 406 will move to both sides, so that the distance between the two sets of limiting plates 406 is just enough to limit the nut 408 and prevent it from rotating naturally. The circular plate 503 can prevent the limiting plates 406 from moving off the surface of the positive and negative threads 504, and the limiting rod 409 can limit the movement of the limiting plates 406.

[0037] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0038] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
