They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1-Figure 7 As shown, a connection reinforcement structure of high-strength steel beams and steel columns for construction includes a diagonal brace 1 connected between the steel beam and the steel column, one end of the diagonal brace 1 is connected to the steel beam, and the other end of the diagonal brace 1 is connected to the steel column. The steel column is provided with a supporting part and an adjusting part, the supporting part is located at the lower side of the diagonal brace 1, and the adjusting part is contacted and arranged at the lower side of the steel beam; The support part includes an integrally formed support nut 2, a fixing sleeve 3 and a support ring 4, the diagonal support 1 is arranged in contact with the support ring 4, the support nut 2 and the support ring 4 are both threadedly connected to the steel column, an interlayer 5 is arranged between the inner wall of the fixing sleeve 3 and the steel column, an adhesive medium is introduced into the interlayer 5 through the fixing sleeve 3, a quick-release component is arranged inside the fixing sleeve 3, the quick-release component is connected with the interlayer 5, and the fixing sleeve 3 and the steel column are quickly unlocked by the quick-release component.

[0026] Steel columns serve as vertical supporting members, and steel beams serve as horizontal supporting members, and the two are often overlapped vertically. When connecting steel beams and steel columns, the height of the ends of the steel beams needs to be adjusted so that the two reach a suitable overlapping height and angle. The adjustment process requires the use of lifting equipment and manual work, which is very inconvenient. The present application supports the steel beam through an adjustment part, and fine-tunes the connecting end 14 of the steel beam by adjusting the height of the adjustment part, so that the steel beam and the steel column reach a suitable installation angle. The diagonal brace 1 serves as the main connecting component between the steel beam and the steel column, and plays a major supporting role for the steel beam, with the lower end of the diagonal brace 1 serving as the main force point. The lower end of the diagonal brace 1 is supported by the support part to ensure that the supporting effect of the diagonal brace 1 is maintained.

[0027] A threaded section is arranged on the upper part of the steel column, the supporting part is threadedly connected to the threaded section, and the connection position between the steel beam and the steel column can be adjusted along the height direction of the steel column.

[0028] like Figure 7 As shown, a filling cavity 6 is arranged inside the fixing sleeve 3 , a filling tube 7 is arranged outside the filling cavity 6 , and a plurality of filling holes 8 are arranged between the filling cavity 6 and the interlayer 5 .

[0029] The adhesive medium is filled into the filling cavity 6 through the filling tube 7, so that the adhesive medium is filled into the interlayer 5 after passing through the filling hole 8, and the fixing sleeve 3 and the steel column are bonded by the adhesive medium to improve the supporting strength of the supporting part and avoid the instability of the connection structure caused by thread damage.

[0030] like Figure 7 As shown, the fixing sleeve 3 is provided with a plurality of installation cavities inside, and the plurality of installation cavities are evenly arranged along the circumferential direction of the fixing sleeve 3, and the end of the installation cavity opposite to the interlayer 5 is inclined toward the thread unlocking direction of the supporting part; The quick-release assembly includes explosives 9 filled in the installation cavity and an ignition assembly 10.

[0031] The ignition assembly 10 is used to ignite the explosive 9. After the explosive 9 is ignited, a shock wave is quickly released into the interlayer 5. The shock wave impacts in the direction of thread unlocking, causing the adhesive medium in the interlayer 5 to vibrate and separate from the threads on the steel column, making it easy to disassemble the supporting part.

[0032] like Figure 1 and Figure 4 As shown, the adjustment part includes two C-shaped elastic support plates 11, and a connecting groove is opened in the length direction of the elastic support plate 11. The opening directions of the two elastic support plates 11 are opposite and cross-arranged. A positioning platform 12 is arranged on the lower side of the elastic support plate 11, and the positioning platform 12 is fixedly connected to the steel column. The steel beam is arranged in contact with the upper part of the elastic support plate 11.

[0033] The connecting groove is used to accommodate the steel column, so that the elastic support plate 11 can freely adjust the height, and the positioning platform 12 can be integrally formed or welded with the steel column.

[0034] like Figure 3 and Figure 4 As shown, an adjustment slot 13 is provided on the upper portion of the steel column, a connecting end 14 is provided at one end of the steel beam, the connecting end 14 passes through the adjustment slot 13, a mounting plate 15 is movably provided on the connecting end 14, and a limiting pin 16 is provided on the side of the mounting plate 15 away from the steel beam.

[0035] The connecting end 14 can also be a square structure as shown in the figure, so that the mounting plate 15 is provided with a directional hole correspondingly for accommodating the connecting end 14. The corresponding connecting section can also be circular, and the connecting end 14 can be connected with a nut correspondingly to lock the connecting end 14 with the steel column.

[0036] like Figure 1 and Figure 4As shown, at least two transverse support rods 17 are arranged between the intersection sections of the two elastic support plates 11, and an adjusting screw rod 18 is arranged on the inner upper part of the steel column. The adjusting screw rod 18 is vertically threadedly connected to the support rod 17, and the adjusting screw rod 18 is used to adjust the distance between adjacent support rods 17. When the distance between adjacent support rods 17 increases, the height of the adjusting part increases, and when the distance between adjacent support rods 17 decreases, the height of the adjusting part decreases.

[0037] The height of the elastic support plate 11 can be adjusted by adjusting the distance between the two support rods 17. The adjusting screw rod 18 is set as a positive and negative threaded rod, so that when the adjusting screw rod 18 rotates, the two support rods 17 move in opposite directions.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, a transverse adjusting rod 19 is provided on the upper part of the steel column, and bevel gears are provided at the middle part of the adjusting rod 19 and the end of the adjusting screw rod 18, and the two bevel gears are meshed and connected. A hexagonal hole 20 is provided at the outer end of the adjusting rod 19, and the hexagonal hole 20 is used to accommodate the hexagonal.

[0039] The bonding medium is cement, concrete, anchor glue or asphalt.

[0040] Directions: When the device is used, the steel beam and the steel column are first preliminarily positioned and connected, so that the connecting end 14 of the steel beam is inserted into the connecting groove of the steel column, and the height of the steel beam is adjusted by the adjusting part to adjust the steel beam to a suitable height; During the adjustment process, the adjusting rod 19 is driven to rotate through the hexagonal prism, so that the adjusting screw 18 rotates to drive the two support rods 17 to move. As the distance between the two support rods 17 increases, the steel beam is raised, and the distance between the two support rods 17 decreases, and the steel beam is lowered. When the height of the steel beam is adjusted to a suitable position, the mounting plate 15 is sleeved on the outside of the connecting end 14, and the steel beam is locked by the limit pin 16.

[0041] After the above adjustment is completed, the support part is adjusted to the lower side of the diagonal brace 1, and the support nut 2 is rotated to make the support part press against the lower end of the diagonal brace 1, and the connection between the steel beam and the steel column is locked. The upper end of the diagonal brace 1 is connected to the steel beam by bolts or welding; The adhesive medium is introduced into the fixing sleeve 3, and the adhesive medium is squeezed into the interlayer 5 through the filling hole 8 to bond the fixing sleeve 3 and the steel column, thereby increasing the connection strength between the supporting part and the steel column; When the steel beam and the steel column need to be disassembled, the connection between the adhesive medium and the steel column is released by the quick-disassembly assembly, and the steel column and the steel beam can be disassembled. The specific disassembly process is as follows: The ignition assembly 10 is powered by an external power supply or a built-in power supply, and the explosive 9 is ignited by the ignition assembly 10. The shock wave generated by the explosion of the explosive 9 is quickly pushed into the interlayer 5, so that the adhesive medium in the interlayer 5 is separated from the fixing sleeve 3 and the steel column; The supporting part can be removed by rotating it, and then the steel column and the steel beam can be disassembled.
