Description

Technical Field

[0001] The present invention relates to the technical field of reinforcement devices, and more specifically, it is a connection reinforcement structure for high-strength steel beams and steel columns used in buildings. Background Art

[0002] In the construction field, building components are important factors for the completion of a building. No matter what building components are used for construction, the performance of the building structure and components in terms of strength, stiffness, stability, etc. under various conditions must be satisfied. Steel structure support beams are indispensable components in buildings, with advantages such as high compressive strength, good plastic deformation, and short construction period, and are widely used. Common steel structure support beams are mostly connection structures between steel beams and steel columns. Existing connection structures between steel beams and steel columns are generally connected through structures such as welding, bolts, and pins. As the service life increases, connection structures such as threads are prone to loosening, affecting the overall stability of steel structure buildings. And during use, the height of the steel beam needs to be continuously adjusted to reach the appropriate installation height, and the adjustment process is rather inconvenient.

[0003] Therefore, the present application provides a connection reinforcement structure for high-strength steel beams and steel columns used in buildings, which solves the problems in the prior art that it is inconvenient to frequently adjust the height of the steel beam during the installation of the steel structure and the connection at the steel structure joint is prone to loosening, affecting the connection stability of the steel structure. Summary of the Invention

[0004] To solve the above problems, the present invention provides a connection reinforcement structure for high-strength steel beams and steel columns used in buildings.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a connection reinforcement structure for high-strength steel beams and steel columns used in buildings, including a diagonal brace connected between the steel beam and the steel column. One end of the diagonal brace is connected to the steel beam, and the other end of the diagonal brace is connected to the steel column. The steel column is provided with a support part and an adjustment part. The support part is located below the diagonal brace, and the adjustment part is in contact with the lower side of the steel beam.

[0006] The support part includes a support nut, a fixing sleeve, and a support ring that are integrally formed. The diagonal brace is in contact with the support ring. Both the support nut and the support ring are threadedly connected to the steel column. A sandwich layer is provided between the inner wall of the fixing sleeve and the steel column. A bonding medium is introduced into the sandwich layer through the fixing sleeve. A quick-release component is provided inside the fixing sleeve, and the quick-release component communicates with the sandwich layer. The fixing sleeve and the steel column are quickly unlocked through the quick-release component.

[0007] As an optimization, a filling cavity is provided inside the fixing sleeve. A filling pipe is provided on the outer side of the filling cavity. A number of filling holes are provided between the filling cavity and the sandwich layer.

[0008] As an optimization, several installation cavities are arranged inside the fixed sleeve, and the several installation cavities are evenly arranged along the circumferential direction of the fixed sleeve. One end of the installation cavity opposite to the interlayer is inclined towards the thread unlocking direction of the supporting part;

[0009] The quick-disassembly component includes explosives filled inside the installation cavity and an ignition component.

[0010] As an optimization, the adjusting part includes two C-shaped elastic support plates. A connecting groove is arranged in the length direction of the elastic support plate. The opening directions of the two elastic support plates are opposite and cross each other. A positioning platform is arranged on the lower side of the elastic support plate, and the positioning platform is fixedly connected to the steel column. The steel beam is in contact with the upper part of the elastic support plate.

[0011] As an optimization, an adjusting groove is arranged at the upper part of the steel column. One end of the steel beam is provided with a connecting end, and the connecting end passes through the adjusting groove. An installation plate is movably arranged at the connecting end, and a limiting pin is arranged on the side of the installation plate away from the steel beam.

[0012] As an optimization, at least two transverse support rods are arranged between the cross sections of the two elastic support plates. An adjusting screw rod is arranged at the upper inner side of the steel column, and the adjusting screw rod is vertically threadedly connected to the support rod. The adjusting screw rod is used to adjust the distance between adjacent support rods. When the distance between adjacent support rods increases, the height of the adjusting part increases. When the distance between adjacent support rods decreases, the height of the adjusting part decreases.

[0013] As an optimization, a transverse adjusting rod is arranged at the upper part of the steel column. Bevel gears are arranged at the middle part of the adjusting rod and the end part of the adjusting screw rod, and the two bevel gears are meshed and connected. A hexagonal hole is arranged at the outer end of the adjusting rod, and the hexagonal hole is used to accommodate a hexagon.

[0014] As an optimization, the bonding medium is cement, concrete, planting bar glue or asphalt.

[0015] As an optimization, the steel beam and the steel column are initially positioned and connected. The height of the steel beam is adjusted through the adjusting part to adjust the steel beam to a suitable height;

[0016] After the adjustment is completed, the supporting part is adjusted to the lower side of the diagonal brace, so that the supporting part presses against the lower end of the diagonal brace, locks the connection part of the steel beam and the steel column, and injects the bonding medium into the fixed sleeve to increase the connection strength between the supporting part and the steel column.

[0017] As an optimization, when the steel beam and the steel column need to be disassembled, the connection between the bonding medium and the steel column is released through the quick-disassembly component, and then the steel column and the steel beam can be disassembled.

[0018] A connection and reinforcement structure for high-strength steel beams and steel columns in construction has the following advantages:

[0019] In this application, a diagonal brace is provided between the steel beam and the steel column. The lower end of the diagonal brace is fixed through the support part to prevent loosening of the connection between structures. At the same time, an adjustment part is provided on the upper side of the support part. By rotating the adjustment screw rod, the height of the adjustment part can be adjusted to achieve precise adjustment of the connection height between the steel beam and the steel column, improving the stability of the steel structure connection.

[0020] After the support part is installed, an adhesive medium can be introduced into the support part to improve the stability of the connection between the support part and the steel column, preventing unstable connection caused by damage to the threaded structure. At the same time, a quick-disassembly component is provided inside the support part, which can quickly loosen the adhesive medium in a blasting manner, facilitating the quick removal of the support part.

DETAILED DESCRIPTION OF THE INVENTION

[0029] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the invention product is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0030] As Figures 1 - 7 shown, a connection and reinforcement structure for high-strength steel beams and steel columns in 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 support part and an adjustment part. The support part is located below the diagonal brace 1, and the adjustment part is in contact with the lower side of the steel beam;

[0031] The support part includes an integrally formed support nut 2, a fixing sleeve 3, and a support ring 4. The diagonal brace 1 is in contact with the support ring 4. Both the support nut 2 and the support ring 4 are threadedly connected to the steel column. A sandwich layer 5 is provided between the inner wall of the fixing sleeve 3 and the steel column. A bonding medium is introduced into the sandwich layer 5 through the fixing sleeve 3. A quick-release component is provided inside the fixing sleeve 3, and the quick-release component communicates with the sandwich layer 5. The fixing sleeve 3 and the steel column are quickly unlocked through the quick-release component.

[0032] The steel column serves as a vertical support member, and the steel beam serves as a horizontal support member. The two are often perpendicularly overlapped. When the steel beam and the steel column are connected, it is necessary to adjust the height of the end of the steel beam to make the two reach a suitable overlapping height and angle. During the adjustment process, hoisting equipment and manual labor are required for cooperation, and the operation is very inconvenient. In this application, the steel beam is supported by the adjustment part. By adjusting the height of the adjustment part, the connection end 14 of the steel beam is finely adjusted to make the steel beam and the steel column reach a suitable installation angle. The diagonal brace 1 serves as the main connection component between the steel beam and the steel column and plays a main supporting role for the steel beam. The lower end of the diagonal brace 1 is the main stress point. The lower end of the diagonal brace 1 is supported by the support part to ensure the maintenance of the supporting effect of the diagonal brace 1.

[0033] A threaded section is provided at the upper part of the steel column, and the support part is threadedly connected to the threaded section. The connection position between the steel beam and the steel column can be adjusted along the height direction of the steel column.

[0034] As Figure 7 shown, a filling cavity 6 is provided inside the fixing sleeve 3, a filling pipe 7 is provided outside the filling cavity 6, and a plurality of filling holes 8 are provided between the filling cavity 6 and the sandwich layer 5.

[0035] The bonding medium is filled into the filling cavity 6 through the filling pipe 7, and the bonding medium fills the sandwich layer 5 after passing through the filling holes 8. The fixing sleeve 3 and the steel column are bonded by the bonding medium, improving the supporting strength of the supporting part and avoiding the instability of the connection structure caused by the damage of the thread.

[0036] As Figure 7 shown, a plurality of installation cavities are arranged inside the fixing sleeve 3, and the plurality of installation cavities are uniformly arranged along the circumferential direction of the fixing sleeve 3. One end of the installation cavity opposite to the sandwich layer 5 is inclined towards the thread unlocking direction of the supporting part;

[0037] The quick-disassembly component includes explosives 9 filled inside the installation cavity and an ignition component 10.

[0038] The ignition component 10 is used to ignite the explosives 9. After the explosives 9 are ignited, shock waves are quickly released into the sandwich layer 5. The shock waves impact towards the thread unlocking direction, causing the bonding medium in the sandwich layer 5 to vibrate and separate from the threads on the steel column, facilitating the disassembly of the supporting part.

[0039] As Figure 1 and Figure 4 shown, the adjusting part includes two C-shaped elastic support plates 11. A connecting groove is formed in the length direction of the elastic support plate 11. The opening directions of the two elastic support plates 11 are opposite and cross each other. 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 in contact with the upper part of the elastic support plate 11.

[0040] The connecting groove is used to accommodate the steel column, enabling the elastic support plate 11 to freely adjust its height. The positioning platform 12 can be integrally formed or welded with the steel column.

[0041] As Figure 3 and Figure 4 shown, an adjusting groove 13 is formed in the upper part of the steel column. One end of the steel beam is provided with a connecting end 14, and the connecting end 14 passes through the adjusting groove 13. An installation plate 15 is movably arranged on the connecting end 14, and a limit pin 16 is arranged on the side of the installation plate 15 away from the steel beam.

[0042] The connecting end 14 can also be the square structure shown in the figure, so that the installation plate 15 is correspondingly provided with holes in a specific direction for the connecting end 14 to pass through. The corresponding connecting section can also be circular, and the connecting end 14 can be connected by a nut correspondingly, so as to lock the connecting end 14 with the steel column.

[0043] As Figure 1 and Figure 4As shown, at least two transverse support rods 17 are provided between the cross - sections of the two elastic support plates 11. An adjusting screw rod 18 is provided at the upper inner side of the steel column. The adjusting screw rod 18 is vertically and threadedly connected to the support rod 17. 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 rises; when the distance between adjacent support rods 17 decreases, the height of the adjusting part drops.

[0044] By adjusting the distance between the two support rods 17, the height of the elastic support plate 11 can be adjusted. The adjusting screw rod 18 is set as a left - hand and right - hand threaded rod. When the adjusting screw rod 18 rotates, the two support rods 17 move in opposite directions.

[0045] As Figure 1 、 Figure 4 and Figure 5 shown, a transverse adjusting rod 19 is provided at the upper part of the steel column. Bevel gears are provided at the middle of the adjusting rod 19 and the end of the adjusting screw rod 18, and the two bevel gears are meshed. A hexagonal hole 20 is provided at the outer end of the adjusting rod 19, and the hexagonal hole 20 is used to accommodate a hexagonal bar.

[0046] The bonding medium is cement, concrete, anchor glue or asphalt.

[0047] Usage method:

[0048] When the device is specifically used, first, the steel beam and the steel column are preliminarily positioned and connected. The connecting end 14 of the steel beam is inserted into the connecting groove of the steel column. The height of the steel beam is adjusted through the adjusting part to adjust the steel beam to a proper height.

[0049] During the adjustment process, the adjusting rod 19 is rotated by driving with a hexagonal bar, so that the adjusting screw rod 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 lifted; as the distance between the two support rods 17 decreases, the steel beam is lowered. After the height of the steel beam is adjusted to a proper position, the mounting plate 15 is sleeved outside the connecting end 14, and the steel beam is locked by the limit pin 16.

[0050] After the above adjustment is completed, the support part is adjusted to the lower side of the diagonal brace 1. The support nut 2 is rotated to make the support part press against the lower end of the diagonal brace 1 to lock the connection part between the steel beam and the steel column. The upper end of the diagonal brace 1 is connected to the steel beam by bolts or welding.

[0051] The bonding medium is introduced into the fixing sleeve 3, and the bonding medium is squeezed into the inner layer 5 through the filling hole 8 to bond the fixing sleeve 3 and the steel column, increasing the connection strength between the support part and the steel column.

[0052] When the steel beam and the steel column need to be disassembled, the connection between the bonding medium and the steel column is released through the quick-disassembly component, and then the steel column and the steel beam can be disassembled. The specific disassembly process is as follows:

[0053] Power the ignition component 10 in the form of an external power supply or an internal power supply. Ignite the explosive 9 through the ignition component 10. The shock wave generated by the explosion of the explosive 9 is quickly pushed into the interior of the sandwich layer 5, separating the bonding medium in the sandwich layer 5 from the fixing sleeve 3 and the steel column;

[0054] Rotate the support part, and then the support part can be removed, and further, the steel column and the steel beam can be disassembled.

[0055] The above specific implementation manners are only specific cases of the present invention. The patent protection scope of the present invention includes, but is not limited to, the product forms and styles of the above specific implementation manners. Any connection and reinforcement structure of a high-strength steel steel beam and a steel column for construction that conforms to the claims of the present invention and any appropriate changes or modifications made by those of ordinary skill in the corresponding technical field shall fall within the patent protection scope of the present invention.
