Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a modular adjustable prefabricated building beam-column joint connection device. Background Technology

[0002] Prefabricated construction, also known as modular construction, is a construction method that involves manufacturing building components (such as walls, floor slabs, beams, and columns) in a factory environment and then transporting these components to the construction site for assembly. This method not only significantly shortens the construction cycle and reduces on-site wet work, but also effectively reduces human error and material waste. Prefabricated construction, due to its standardized production and modular design, offers advantages such as easier quality control and superior environmental performance. Furthermore, it provides greater design flexibility and personalization to meet the diverse needs of users while ensuring structural safety.

[0003] In modular prefabricated buildings, beam-column joint connection devices are key components affecting structural stability, construction efficiency, and adaptability. Traditional joints mostly use welding, bolts, or cast-in-place concrete connections, which, while meeting basic load-bearing requirements, suffer from limited adjustability, insufficient load-bearing capacity and ductility, and low assembly efficiency. Conventional rigid joints struggle to cope with three-dimensional spatial deviations, especially exhibiting poor adaptability in irregular or non-orthogonal structures; load transfer relies on a single fastener, leading to stress concentration and loosening and deformation under long-term dynamic loads; the installation process is complex, requiring high-precision alignment and specialized tools, resulting in long construction cycles and low tolerance for errors, thus hindering the development of modular buildings. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a modular adjustable prefabricated building beam-column joint connection device.

[0005] A modular adjustable prefabricated building beam-column joint connection device includes a base, steel columns, pads, extension frames, U-shaped fixing frames, fixing screws, and third fasteners. Steel columns are connected to both the upper and lower sides of the base, which are open on both sides. Pads are connected to the outer walls of the base, each pad having at least two fixing holes. U-shaped fixing frames are snapped onto the outer walls of the base via the pads. Extension frames are slidably connected to the side of the U-shaped fixing frames away from the base. Third fasteners are connected to the base circumferentially. Fixing screws are threaded onto the extension frames. The third fasteners and fixing screws are symmetrically arranged vertically. The fixing screws penetrate the U-shaped fixing frames and the base, and are fixedly connected to the base via the third fasteners. Mounting holes are provided on the side of the extension frames away from the base.

[0006] In a preferred embodiment of the present invention, it further includes a first fastener, a right-angle fixing bracket, and a second fastener. At least two first fasteners are connected between the base sidewall and the U-shaped fixing bracket. The base sidewall is connected to the right-angle fixing bracket through the first fasteners. The side of the right-angle fixing bracket closest to the base is connected to a second fastener. The second fasteners are all connected to the steel column.

[0007] In a preferred embodiment of the present invention, a fourth fastener is also included. Each extension frame has a sliding groove, and the extension frame and the U-shaped fixing frame are connected by a fourth fastener. The fourth fastener is slidably connected to the sliding groove.

[0008] In a preferred embodiment of this utility model, a fifth fastener is also included. The fifth fastener is connected to each pad and passes through the fixing hole and the reinforcing frame.

[0009] In a preferred embodiment of the present invention, a reinforcing frame is further included. A grid-shaped reinforcing frame is connected inside the base. The reinforcing frame has through holes spaced apart circumferentially. The fifth fastener and the third fastener are both located inside the through holes.

[0010] In a preferred embodiment of this utility model, a steel spring is also included, with steel springs connecting both the upper and lower third fasteners.

[0011] Compared with the prior art, the present invention has the following advantages: The present invention is provided with a pad, a right-angle fixing frame, a first fastener, a second fastener, a U-shaped fixing frame, a fourth fastener and a fifth fastener.

The fifth fastener 11 passes through the fixing hole 201 and the reinforcing frame 3. The fifth fastener 11 and the third fastener 901 are both located in the through holes 4. A steel spring 12 is fixedly connected between the upper and lower third fasteners 901. The steel spring 12 can provide a certain elastic deformation capacity and can absorb some energy under earthquake or wind vibration, thereby improving the structural toughness of this connection device.
