[0022] Please refer to Figures 1 - 4 , an embodiment provided by the present invention: A high-rise building steel structure that is easy to disassemble and assemble, including a box column body 1;

[0023] When multiple box column bodies 1 are assembled, the top plates 4 and the bottom plates 8 on different box column bodies 1 are assembled, and the connecting bolts 6 pass through the first flange holes 10 and the second flange holes 11, and at the same time, the bottom ends of the connecting bolts 6 are sleeved with locking nuts 7 for locking and fixing;

[0024] The top plate 4 is welded to the top end of the box column body 1, and positioning guide blocks 5 are evenly installed on the top end of the top plate 4, and the positioning guide blocks 5 are closely distributed around the center of the top plate 4;

[0025] The number of the positioning guide blocks 5 corresponds to the number of the first flange holes 10, and the positions of the positioning guide blocks 5 and the first flange holes 10 correspond one by one inside and outside;

[0026] The cross-section of the positioning guide block 5 is triangular, the inner height of the positioning guide block 5 is lower than the outer height, that is, the top end of the positioning guide block 5 gradually rises from inside to outside;

[0027] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, when in use, by using the corresponding relationship between the positioning guide block 5 and the positioning guide groove 9, and the special structure of the positioning guide block 5, it can slide along the inside of the positioning guide groove 9, so as to be completely clamped into the inside of the positioning guide groove 9, so as to realize the connection function between the upper and lower box column bodies 1, so as to avoid rotating and adjusting the box column body 1, and the one-to-one correspondence between the second flange holes 11 and the first flange holes 10 can be realized, reducing the assembly operation steps;

[0028] The first flange holes 10 are uniformly arranged inside the top plate 4 on the outer side of the positioning guide block 5, and the positions of the second flange holes 11 correspond one by one to the positions of the positioning guide grooves 9. The bottom plate 8 is welded to the bottom end of the box column body 1, and the positioning guide grooves 9 are arranged in the bottom plate 8 corresponding to the structure of the upper positioning guide block 5. The second flange holes 11 are uniformly arranged inside the bottom plate 8 on the outer side of the positioning guide grooves 9. The bottom end of the top plate 4 and the top end of the bottom plate 8 are both connected with rectangular hoops 3, and the rectangular hoops 3 are sleeved outside the box column body 1;

[0029] Reinforcing blocks 12 are uniformly welded between the rectangular hoop 3 and the top plate 4 and the bottom plate 8, and the cross-section of the reinforcing block 12 is triangular, and its hypotenuse faces outwards;

[0030] Specifically, as Figure 1 、 Figure 4 shown, when in use, by using the function of the reinforcing block 12, the contact area between the rectangular hoop 3 and the top plate 4 and the bottom plate 8 is increased, the connection tightness is improved, and at the same time, by using its special structure, it is convenient to improve the supporting effect on the top plate 4 and the bottom plate 8 and prevent them from deforming;

[0031] There are 2 uniformly connected between the upper and lower 3s, and there are four 2s, and at the same time, each 2 is located on the single outer wall of 1;

[0032] There are four reinforcing mechanisms 2 uniformly connected between the upper and lower rectangular hoops 3, and at the same time, each reinforcing mechanism 2 is located on the single outer wall of the box column body 1;

[0033] The strengthening mechanism 2 includes a pressure-bearing block 201 installed on the outer side of the box column main body 1. A positioning groove 203 is formed on the side of the pressure-bearing block 201 close to the box column main body 1. A positioning block 204 is inserted into the interior of the positioning groove 203, and one end of the positioning block 204 is welded to the outer side of the box column main body 1. Connecting rods 202 are uniformly welded to the outer side of the pressure-bearing block 201, and the other ends of the connecting rods 202 are respectively welded to the end faces of the upper and lower rectangular hoops 3.

[0034] The cross-section of the pressure-bearing block 201 is circular, and the pressure-bearing block 201 is located at the central position on the outer side of the box column main body 1. The connecting rods 202 are distributed in an X shape outside the pressure-bearing block 201.

[0035] Specifically, as Figure 1 , Figure 4 shown, when in use, by the cooperation of the pressure-bearing block 201 and the connecting rods 202, combined with the function of the rectangular hoop 3, it is convenient to form a wrapping around the outside of the box column main body 1 to prevent the deformation of the box column main body 1, and by the supporting function of the connecting rods 202, it is further prevented that the upper and lower ends of the box column main body 1 are compressed and deformed.

[0036] Working principle: When the present utility model is in use, first, the box column main body 1 is lifted by using the first flange hole 10, and the box column main body 1 is placed on the upper end of the lower box column main body 1, so that the bottom plate 8 contacts the top plate 4. Through the special structures of the positioning guide groove 9 and the positioning guide block 5, the positioning guide block 5 slides along the positioning guide groove 9. By the triangular cross-section structure and the inclined top structure of the positioning guide block 5, the positioning guide block 5 automatically fits with the positioning guide groove 9, and then the positions of the second flange hole 11 and the first flange hole 10 are corresponding. Then, through the action of the connecting bolts 6 and the locking nuts 7, the assembly of the upper and lower two box column main bodies 1 is realized.

[0037] Secondly, by the function of the rectangular hoop 3, the structural strength at both ends of the box column main body 1 is improved to prevent its compression deformation, and by the function of the connecting rods 202, it is convenient to transfer the compression force received by the rectangular hoop 3 to the pressure-bearing block 201. And due to the circular structure of the pressure-bearing block 201, the bearing pressure is evenly distributed on the pressure-bearing block 201, thereby further reducing the deformation at the butt joint of the box column main body 1. At the same time, by the cooperation of multiple groups of connecting rods 202, the rectangular hoop 3 forms a frame structure to limit the box column main body 1 to further prevent the deformation of the box column main body 1.
