Inside the square tube 2, there is a connection mechanism connecting to a plurality of I-beams 5. The connection mechanism includes a connection plate 3 and fixing ears 4. Four groups of fixing ears 4 are integrally formed on the outer periphery of the connection plate 3. The inner side of the fixing ear 4 is used to accommodate the web of the I-beam 5, and the upper and lower ends of the fixing ear 4 are used to support the flange of the fixing ear 4. Two upper and lower groups of connection plates 3 are fixedly connected through a docking mechanism.

[0019] In this embodiment: First, fix the edge fixing plate 1 to the four-sided side walls through fixing parts. Then, use one of the fixing parts or welding methods to fix the connection mechanism at the edge to the support plate 6. Then, connect the I-beams 5 to the connection mechanism in sequence. After docking, weld and fix the I-beams 5 to the fixing ears 4.

[0020] When the upper and lower connection mechanisms are docked and fixed through the docking mechanism, after all the steel frames below are installed and fixed, lay the cement board containing steel bars on the top of the upper I-beams 5 and fix it with impact nails.

[0021] Please refer specifically to Figure 3 and Figure 4 , the docking mechanism includes docking grooves 7 fixedly connected to the mutually adjacent surfaces of the upper and lower groups of connection plates 3. The docking grooves 7 are in a hollow cross-shaped structure. A docking frame 8 is inserted into the inner wall of the docking grooves 7. The docking mechanism also includes counterbores 9 opened on the mutually opposite surfaces of the upper and lower groups of connection plates 3. Through holes are opened inside the docking frame 8 and inside the connection plates 3. The diameter of the through holes is smaller than the diameter of the counterbores 9, and the centers of the through holes coincide with the centers of the counterbores 9.

The bottom end of the screw 10 penetrates into the lower counterbore 9, and a nut 11 is threadedly connected to the outer wall of the bottom end of the screw 10. The nut 11 is located in the lower counterbore 9.

[0024] In this embodiment: Before welding the docking frame 8 to the two docking grooves 7, the screw 10 is passed through the upper counterbore 9 and the through hole until it enters the lower counterbore 9, and then a tool is used to screw the nut 11 tightly onto the lower outer wall of the screw 10. After screwing it completely, at this time, the hexagonal block of the screw 10 and the nut 11 are respectively located in the upper and lower counterbores 9, avoiding affecting the laying of the cement board.
