The limiting block 32 is fixedly installed between the clamping block 31 and the crossbar 2, and the width of the limiting block 32 is greater than the slot width of the slot 13. The limiting block 32 can fit with the outer side surface of the column 1, and the clamping block 31 fits with the inner side wall of the cavity 11 to improve the stability of the clamping block 31 after installation;

[0047] The two sides of the end of the card block 31 away from the cross bar 3 are symmetrically provided with connecting surfaces 311, and the connecting surfaces 311 are set to an inclined structure, and the slope of the connecting surfaces 311 is 45 degrees. The design of the inclined structure facilitates the mutual fit of multiple card blocks 31 after being inserted into the cavity 11, thereby improving the stability of the card blocks 31 after installation;

[0048] The oblique rod 4 is arranged between the positioning seat 16 and the cross bar 3, and the oblique rod 4 is arranged as an inclined structure. A connecting seat 41 is fixedly installed at the top of the oblique rod 4, and the connecting seat 41 is installed in the middle of the cross bar 3. The connecting seat 41 can be connected to the cross bar 3 by bolts to realize the fixing of the oblique rod 4;

[0049] Moreover, the cross section of the oblique rod 4 is set to an "I"-shaped structure, and the middle of the top of the oblique rod 4 is in contact with the outer wall of the cross bar 3. The design of the "I"-shaped structure improves the anti-twisting performance of the oblique rod 4. The bottom end of the oblique rod 4 is set on the inner side of the positioning seat 16.

Multiple beam-slabs 5 can form the layer plate of the steel structure building.

[0051] In summary, in practical applications of the present invention, the columns 1, the beams 2 and the crossbars 3 form the main frame of the steel structure building, the diagonal bars 4 can realize the reinforcement between the crossbars 3 and the columns 1, and the beams 5 can be overlapped on the crossbars 2 to form the layer plate structure of the steel structure building;

[0052] When assembling the steel structure building, first connect the column 1 with the cross bar 3, insert the block 31 at one end of the cross bar 3 into the corresponding slot 13, and then push the cross bar 3 downward so that the cross bar 3 drives the block 31 to move downward until the block 31 is inserted into the slot 14. At this time, the block 31 fits with the inner wall of the cavity 11, and the limit block 32 fits with the outer wall of the column 1. The cross bar 3 and the column 1 are spliced. During the insertion process of the block 31, the block 31 squeezes the movable block 1222 so that the movable block 122 enters the installation slot 121. After the block 31 is inserted into the slot 14, the movable block 122 is reset under the elastic action of the inner elastic plate 123. At this time, the movable block 122 can limit the top of the block 31 so that the block 31 is fixed in the slot 14 to ensure the connection stability between the cross bar 3 and the column 1.

[0053] A plurality of cross bars 3 and the column 1 form a frame structure. After the assembly is completed, the oblique bar 4 is placed between the column 1 and the cross bar 3, and the two ends of the oblique bar 4 are respectively fitted with the column 1 and the cross bar 3. At this time, the bottom end of the oblique bar 4 is inserted into the inside of the positioning seat 16, and the position between the oblique bar 4 and the positioning seat 16 can be fixed by bolts. At the same time, the connection seat 41 at the top of the oblique bar 4 is fixed to the cross bar 3 by bolts, so that the installation of the oblique bar 4 can be realized. The oblique bar 4 can improve the stability of the column 1 and the cross bar 3 after installation;

[0054] After the columns 1 and the crossbars 3 are assembled, they form a single-layer structure of the steel structure building. The crossbeam 2 is placed at the bottom of the column 1, and the plugs 21 at both ends of the crossbeam 2 are respectively inserted into the outside of the connecting column 15 at the bottom of the column 1. At this time, the positioning plate 152 at one end of the connecting column 15 fits with one end of the plug 21, and the position between the positioning plate 152 and the plug 21 is fixed by bolts, so that the position between the crossbeam 2 and the column 1 can be fixed. At the same time, the columns 1 of different heights of the steel structure building can be connected to each other through the crossbeam 2 to complete the assembly of the steel structure building.
