[0002] Prefabricated buildings refer to buildings that are assembled on site using prefabricated components produced in factories. This construction method adopts standardized design, factory production, assembly construction, information management, and intelligent application, and is a representative of modern industrialized production methods. The overall frame of a prefabricated building is usually composed of multiple crisscross beams connected together. The longitudinal beams and transverse beams are connected together by welding or bolting after alignment. During the connection process, external force is required to support the two beams, and it is necessary to ensure that the surfaces of the two beams are tightly fitted during support. The support requirements are high. During the welding or bolting process, the beams may vibrate slightly, causing the joints between the two beams to shift. After the shift, the connection angle between the longitudinal beams and the transverse beams will change accordingly, which will cause the entire frame to deflect.

One end of the two slide bars 316 slides through the inner wall of the rotating plate 312 and extends to the top of the rotating plate 312. A connecting block 317 is fixed between the tops of the two slide bars 316. A plurality of locking bolts 318 are provided on the connecting block 317. The bottom ends of the plurality of locking bolts 318 are screwed and fixed to the inner wall of the rotating plate 312. A spring 315 is sleeved on the two slide bars 316. The upper and lower ends of the spring 315 are respectively connected and fixed to the inner wall of the top of the slot 313 and the top of the clamping block 314. When the plug block 322 is inserted into the slot 313, the inclined surface on one side of the clamping block 314 first contacts the slope 324 on the plug block 322. Under the cooperation of the two inclined surfaces, the clamping block 314 is lifted upward, and then falls back downward under the action of the spring 315 and is embedded in the positioning hole 323. The plug block 322 is firmly fixed in the slot 313 through the cooperation of the clamping block 314 and the positioning hole 323, so that the plug plate 321 and the rotating plate 312 are firmly fixed together. To ensure the fixing effect, after the plug plate 321 and the rotating plate 312 are connected, one end of the multiple locking bolts 318 on the connecting block 317 is tightened and fixed to the inner wall of the rotating plate 312. A first groove 3110 is provided in the middle of the inner wall of one side of the fixed plate 311, and second grooves 3111 are provided on both sides of the inner wall of the fixed plate 311 corresponding to the first groove 3110, through grooves 3118 are provided between the inner wall of the fixed plate 311 corresponding to the first groove 3110 and the second grooves 3111 on both sides thereof, and the two second grooves 3111 are connected to the first groove 3110 via the two through grooves 3118, a sliding seat 3119 is slidably connected between the first groove 3110 and the two second grooves 3111, and the sliding seat 3119 is formed by connecting a plurality of sliding blocks to each other, first bases 3114 are fixed at both ends of one side of the sliding seat 3119, and second bases 3116 are fixed at both ends of one side of the rotating plate 312, and the two second bases 3116 are respectively arranged corresponding to the two first bases 3114; A screw rod 3113 is rotatably connected in the first groove 3110, one end of the screw rod 3113 rotates through the inner wall of the fixing plate 311 and extends to the bottom of the fixing plate 311, and a knob is fixed to the bottom end of the screw rod 3113, and guide rods 3112 are fixed in the two second grooves 3111, and the two guide rods 3112 are respectively slidably connected to the sliding seat 3119, and the screw rod 3113 is threadedly connected to the sliding seat 3119; Two connecting rods 319 are arranged between the fixed plate 311 and the rotating plate 312.

The maximum flip angle of the rotating plate 312 is 180 degrees. When flipped 180 degrees, the rotating plate 312 is horizontally connected to the fixed plate 311. Under normal circumstances, there are two usage scenarios of the connecting member 3. The first is that the rotating plate 312 is vertically connected to the fixed plate 311 at 90 degrees. At this time, a crossbeam 2 and a longitudinal beam 1 can be vertically fixed; the second is that the rotating plate 312 is horizontally connected to the fixed plate 311 at 180 degrees. At this time, the two crossbeams 2 or the two longitudinal beams 1 can be linearly connected and fixed; In some other installation and use scenarios, the rotating plate 312 and the fixed plate 311 may also be connected at an inclined angle. In this case, the crossbeams and longitudinal beams can be fixed in an inclined state, or the longitudinal beams and longitudinal beams, and the crossbeams and crossbeams can be fixed in an inclined state. The actual use can be changed accordingly according to the site conditions. The rotating design between the rotating plate 312 and the fixed plate 311 can facilitate the on-site construction needs.
