[0022] Please refer to Figures 1-4 , in the present utility model, a crossbeam structure for prefabricated buildings includes a crossbeam body 1. Two slots 11 are opened on the bottom surface of the crossbeam body 1. A vertical beam 5 is provided inside each slot 11. A through groove 16 is opened on the right side surface of each vertical beam 5. Connection grooves 13 are opened on the left and right side surfaces of the crossbeam body 1. A plug board 18 is jointly provided inside each connection groove 13 and inside each through groove 16. A group of screw holes 14 are opened on the left and right side surfaces of the crossbeam body 1. Fixing plates 4 are fixedly connected to the mutually remote side surfaces of the two plug boards 18. Two threaded holes 17 are opened on the right side surface of each fixing plate 4. Connecting nails 3 are jointly threadedly connected to the inner walls of each threaded hole 17 and the inner walls of each screw hole 14.

[0023] Two grooves 12 are formed in the bottom surface of each crossbeam body 1, and a supporting block 15 is arranged inside each groove 12. The mutually adjacent side surfaces of each group of supporting blocks 15 are fixedly connected to the left and right side surfaces of each vertical beam 5 respectively. When the vertical beam 5 is spliced with the crossbeam body 1, the supporting block 15 will enter the groove 12, which can support the crossbeam body 1. Two mounting blocks 2 are fixedly connected to the upper surface of the crossbeam body 1, and two mounting holes 8 are formed in the right side surface of each mounting block 2. By using the cooperation of the mounting block 2 and the mounting hole 8, it is not only convenient for the staff to hoist the crossbeam body 1, but also convenient for the staff to install objects above the crossbeam body 1.

[0024] Two reinforcing plates 9 are arranged below the crossbeam body 1. Connecting plates 7 are fixedly connected to the bottom end and the top end of each reinforcing plate 9 respectively. One group of the mutually adjacent side surfaces of the two groups of connecting plates 7 are respectively connected to the outer surface of the vertical beam 5 through bolts 6, and the bottom surfaces of the other group of the two groups of connecting plates 7 are respectively connected to the bottom surface of the crossbeam body 1 through bolts 6. After the connecting plates 7 are connected to the vertical beam 5 and the crossbeam body 1, the reinforcing plates 9 will enhance the firmness between the vertical beam 5 and the crossbeam body 1. A stress plate 10 is arranged below the crossbeam body 1, and the left and right side surfaces of the stress plate 10 are fixedly connected to the mutually adjacent side surfaces of the two reinforcing plates 9 respectively. By using the arranged stress plate 10, the pressure borne by the reinforcing plates 9 can be dispersed, further improving the strength of this device. The outer surface of each inserting plate 18 is in contact with the inner wall of the connecting groove 13 and the inner wall of the through groove 16, which can connect the inserting plate 18 with the crossbeam body 1 and the vertical beam 5.

[0025] The working principle of the present utility model is as follows: during use, first fix the two vertical beams 5, then hoist and install the crossbeam body 1, insert the slot 11 on the crossbeam body 1 into the top of the vertical beam 5. When the crossbeam body 1 descends, the supporting block 15 will enter the groove 12, and the crossbeam body 1 will be supported on the two vertical beams 5. Then insert the inserting plate 18 into the through groove 16 and the connecting groove 13, the screw holes 14 will be aligned with the threaded holes 17, and then use the connecting nails 3 to connect between the threaded holes 17 and the screw holes 14, so as to quickly assemble, ensuring the efficiency of the staff in assembling the prefabricated building.
