Description

Technical Field

[0001] This utility model relates to the field of steel frame technology, specifically to a structurally stable steel frame. Background Technology

[0002] A steel frame is a structural system formed primarily of steel through welding, bolting, and other methods. It boasts advantages such as high strength, light weight, and rapid construction, and is widely used in construction, bridges, machinery, and other fields. Structural stability refers to the ability of a steel frame to maintain its shape and dimensions under external forces, without excessive deformation or instability.

[0003] The existing factory building has a large span, but the steel frame used to build the factory building is not long enough. It is necessary to splice two I-beams together. These two I-beams are spliced ​​together by welding, or by placing steel plates at the top, bottom and front and back of the joint and then fixing them to the I-beams with bolts. Both of these connection methods have the problem of time-consuming and labor-intensive installation and disassembly. Welding is prone to cracking of the weld due to tensile force. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a structurally stable steel frame that is easy to install, has stable connections, and ensures that fixing bolts will not be lost, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a structurally stable steel frame, including a left H-beam, a right H-beam on the right side of the left H-beam, a rear connecting block snapped between the left H-beam and the right H-beam, a front connecting block at the front end of the rear connecting block, fixing holes on the outer edges of the left H-beam, the right H-beam, the rear connecting block and the front connecting block, fixing nuts fixedly fitted on the outer edge of the rear connecting block, fixing bolts threadedly connected to the inner wall of the fixing nuts, and long grooves on the inner walls of the rear connecting block and the front connecting block.

[0006] As a preferred technical solution of this utility model: the top of the fixing bolt is provided with a connecting post, the outer edge of the connecting post is provided with a circular groove, and a steel ring is movably sleeved on the outer edge of the circular groove.

[0007] As a preferred technical solution of this utility model: the outer edge of the steel ring is provided with a connecting hole, and the inner wall of the connecting hole is fitted with a clamp.

[0008] As a preferred technical solution of this utility model: a steel wire rope is fixedly assembled on the outer edge of the clamp, and a connecting base is fixedly assembled on the end of the steel wire rope away from the clamp, and the connecting base is fixedly assembled on the front connecting block.

[0009] As a preferred technical solution of this utility model: a limiting hole is provided at the top of the fixing bolt, and a limiting post is movably connected to the inner wall of the limiting hole, and the limiting post is fixedly assembled on the connecting post.

[0010] As a preferred technical solution of this utility model: the connecting column is fixed to the fixing bolt by the connecting bolt, and the top of the connecting bolt and the top of the connecting column are on the same plane.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The stable steel frame structure is achieved by setting a rear connecting block and a front connecting block between the left and right H-beams, and then fixing them with fixing bolts and nuts. This solves the problem of tension between the rear connecting block and the front connecting block. At the same time, the vertical swaying force of the left and right H-beams is also limited by the rear connecting block and the front connecting block. This solves the problems of welding when splicing two H-beams, and placing steel plates at the top, bottom and front and back positions of the joint and fixing them to the H-beams with bolts. Both of these connection methods are time-consuming and labor-intensive to install and disassemble, and welding is prone to cracking of the weld due to tension.

[0013] 2. The stable steel frame structure uses clamps to connect to the connecting holes on the steel ring. At this time, the clamps, steel ring, connecting column and fixing bolts are connected to the connecting base by steel wire rope, so that the fixing bolts will not be lost when disassembly, which facilitates the transportation and storage of the rear connecting block and the front connecting block.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 6 A structurally stable steel frame includes a left I-beam 1, a right I-beam 2 on the right side of the left I-beam 1, a rear connecting block 3 snapped between the left I-beam 1 and the right I-beam 2, a front connecting block 4 at the front end of the rear connecting block 3, fixing holes 5 on the outer edges of the left I-beam 1, the right I-beam 2, the rear connecting block 3 and the front connecting block 4, fixing nuts 6 fixedly fitted on the outer edge of the rear connecting block 3, fixing bolts 8 threadedly connected to the inner wall of the fixing nuts 6, and long grooves 7 on the inner walls of the rear connecting block 3 and the front connecting block 4.

[0023] In the above structure, by placing the rear connecting block 3 and the front connecting block 4 between the left H-beam 1 and the right H-beam 2, and then tightening the fixing bolt 8 onto the fixing nut 6, the rear connecting block 3 and the front connecting block 4 are fixed to the left H-beam 1 and the right H-beam 2. This ensures that the left H-beam 1 and the right H-beam 2 will not separate when subjected to lateral tension. The rear connecting block 3 and the front connecting block 4 can also fix the left H-beam 1 and the right H-beam 2 against downward and upward forces, preventing them from separating due to upward and downward forces. This improves the stability between the left H-beam 1 and the right H-beam 2. At the same time, the installation and disassembly of the left H-beam 1 and the right H-beam 2 are quicker. The weight of the rear connecting block 3 and the front connecting block 4 can be reduced by using the long slot 7.

[0024] In a preferred embodiment: the top of the fixing bolt 8 is provided with a connecting post 11, the outer edge of the connecting post 11 is provided with a circular groove 13, and a steel ring 14 is movably sleeved on the outer edge of the circular groove 13.

[0025] In the above structure, the connecting column 11 can be separated from the fixing bolt 8. A circular groove 13 is opened on the connecting column 11, and a steel ring 14 is installed on the circular groove 13. The steel ring 14 can rotate in the circular groove 13, so that the clamp 16 on the steel ring 14 can also rotate. When the fixing bolt 8 rotates, it can fix the steel ring 14, so that the steel wire rope 17 on the clamp 16 will not be tangled.

[0026] In a preferred embodiment, a connecting hole 15 is provided on the outer edge of the steel ring 14, and a clamp 16 is engaged with the inner wall of the connecting hole 15.

[0027] In the above structure, the clamp 16 can be engaged in the connection hole 15. When the fixing bolt 8 needs to be unscrewed, the clamp 16 can be removed from the connection hole 15, so that the wire rope 17 is not connected to the connecting post 11. At this time, the fixing bolt 8 can be rotated. When the fixing bolt 8 is unscrewed, the clamp 16 is engaged in the connection hole 15 again. At this time, the fixing bolt 8 is connected, so that the fixing bolt 8 is not easily lost when it is not connected to the fixing nut 6.

[0028] In a preferred embodiment: a steel wire rope 17 is fixedly mounted on the outer edge of the clamp 16, and a connecting base 18 is fixedly mounted on the end of the steel wire rope 17 away from the clamp 16. The connecting base 18 is fixedly mounted on the front connecting block 4.

[0029] In the above structure, the wire rope 17 is connected to the connecting column 11 via the clamp 16 and the steel ring 14. The connecting column 11 is connected to the fixing bolt 8 via the connecting bolt 12, so that the fixing bolt 8 can be connected to the connecting base 18 via the wire rope 17. When the fixing bolt 8 is unscrewed, it is connected via the wire rope 17, so that the fixing bolt 8 is connected to the front connecting block 4.

[0030] In a preferred embodiment: a limiting hole 9 is provided at the top of the fixing bolt 8, and a limiting post 10 is movably connected to the inner wall of the limiting hole 9. The limiting post 10 is fixedly assembled on the connecting post 11.

[0031] In the above structure, by using the limiting hole 9 and the limiting post 10 together, when the connecting post 11 is installed on the fixing bolt 8, the limiting post 10 is inserted into the limiting hole 9, and the connecting post 11 cannot rotate, which improves the stability of the connection between the connecting post 11 and the fixing bolt 8.

[0032] In a preferred embodiment, the connecting column 11 is fixed to the fixing bolt 8 by the connecting bolt 12, and the top of the connecting bolt 12 and the top of the connecting column 11 are on the same plane.

[0033] In the above structure, the connecting post 11 is fixed to the fixing bolt 8 by the connecting bolt 12, so that the connecting post 11 and the fixing bolt 8 can be disassembled. When the fixing bolt 8 is stripped, a brand new fixing bolt 8 can be installed on the connecting post 11, which improves the flexibility of the device. By embedding the connecting bolt 12 into the connecting post 11, the top of the connecting post 11 is a flat surface.

[0034] Working principle: In use, the rear connecting block 3 is inserted between the left H-beam 1 and the right H-beam 2, and then the front connecting block 4 is inserted between the left H-beam 1 and the right H-beam 2. At this time, the fixing holes 5 on the rear connecting block 3 and the front connecting block 4 need to be aligned with the fixing holes 5 on the left H-beam 1 and the right H-beam 2. Then, the fixing bolt 8 is tightened onto the fixing nut 6. At this point, the rear connecting block 3 and the front connecting block 4 can fix the left H-beam 1 and the right H-beam 2. After bolt 8 is unscrewed, the limiting pin 10 on the connecting pin 11 is inserted into the limiting hole 9 on the fixing bolt 8. Then, the connecting pin 11 is fixed to the fixing bolt 8 by the connecting bolt 12. Then, the clamp 16 is clamped into the connecting hole 15 on the steel ring 14. At this time, the clamp 16, steel ring 14, connecting pin 11 and fixing bolt 8 are connected to the connecting base 18 by the wire rope 17, so that the fixing bolt 8 will not be lost when it is disassembled, which facilitates the transportation and storage of the rear connecting block 3 and the front connecting block 4.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
