Description

Technical Field

[0001] The present invention relates to the technical field of steel structure fixing, and in particular to a multi-faceted synchronously fastened steel structure fixing seat and a synchronous fastening method thereof. Background Art

[0002] Steel structures are widely used in various types of buildings due to their high strength, fast construction speed, and recyclability. However, when connecting steel structures, especially connecting multiple H-shaped steel beams to columns, multiple bolts are typically required to assemble the H-shaped beams one by one. This piecemeal assembly method is not only time-consuming and labor-intensive, but also prone to uneven connection strength due to inconsistent bolt tightening, thus affecting the stability and safety of the overall structure.

[0003] Because bolts need to be tightened one by one, existing connection methods often fail to achieve the optimal number of bolts and tightening torque, resulting in insufficient connection strength. When subjected to heavy loads or encountering extreme weather conditions, this connection method may loosen or break due to insufficient connection strength, posing a threat to the safety of the building. Summary of the Invention

[0004] In order to make up for the deficiencies of the existing technical problems, the purpose of the present invention is to provide a multi-faceted synchronous fastening steel structure fixing seat and a synchronous fastening method thereof, and to solve the following technical problems: how to achieve efficient and synchronous fastening between H-shaped steel beams and columns to improve connection efficiency and connection strength.

[0005] In order to solve the problems of the prior art, the technical solutions of the present invention are as follows: A multi-faceted synchronously fastened steel structure fixing seat comprises a bottom shell, which is fixedly connected to the outside of a column, a top shell is slidably sleeved on the outside of the bottom shell, and the top shell is slidably connected to the outside of the column. Notches are provided around the bottom shell and the top shell, the notches of the top shell and the notches of the bottom shell are aligned one by one, and plug interfaces of H-beams are formed between the notches of the top shell and the notches of the bottom shell. Guide blocks are rotatably connected at the positions opposite to the notches in the bottom shell, and embedding grooves are provided at the centers of the guide blocks. The embedding grooves are used for inserting the webs of the H-beams. Positioning rods are slidably connected to both sides of the notch in the bottom shell, and one end of the positioning rod is provided with an extrusion inclined surface. Connecting columns are fixedly connected to the four corners of the top shell, and extrusion blocks are fixedly connected to the bottom ends of the connecting columns. The outer walls of both sides of the extrusion blocks are respectively fitted with the corresponding extrusion inclined surfaces.

[0006] Preferably, a guiding slope is provided at the other end of the positioning rod, and the positioning rods are brought closer to each other. The guiding slope enables the positioning rods to more smoothly press the bottom flange plate of the H-beam during the process of approaching each other.

[0007] Preferably, symmetrical positioning blocks are fixedly connected to the bottom of the notch inside the bottom shell, and the positioning blocks are used to be respectively embedded in the waist-shaped holes symmetrically opened at the bottom of the H-beam. During the rotation of the H-beam, the H-beam will drive the guide blocks to rotate, and the positioning blocks will gradually be embedded in the corresponding waist-shaped holes at the bottom of the H-beam to perform preliminary positioning of the H-beam.

[0008] Preferably, thin rods are fixedly connected to the bottom of the top shell at equal intervals, and the thin rods are slidably inserted into the corresponding embedded grooves. The thin rods are used to insert into the embedded grooves during the lowering process of the top shell, squeezing the H-beam to further lock it, increasing the restraining force on the H-beam, and making the H-beam more stable when subjected to external forces.

[0009] Preferably, a connecting portion extends downward from the center of the bottom of the bottom shell, the connecting portion is sleeved on the outside of the column, and two groups of fixing bolts are symmetrically passed through the inside of the connecting portion. The fixing bolts are used to fix the connecting portion to the outside of the column. The fixing bolts provide a method for firmly mounting the entire fixing base on the column, thereby ensuring the stability and reliability of the fixing base.

[0010] Preferably, a long rod is symmetrically fixedly connected to the bottom of the top shell, the long rod passes through the bottom shell and is fixedly connected to a sliding rod inside the end, a movable rod is slidably connected to the outer side of the bottom end of the long rod, sliding holes are provided on both sides of the movable rod, and the two ends of the sliding rod are respectively slidably connected to the corresponding sliding holes, and the long rod is slidably inserted in the gap between one end of a corresponding set of fixing bolts and the bottom shell.

[0011] Preferably, the opening of the embedding groove of the guide block is arranged in an arc-shaped outward expansion, so that the web of the H-beam can be more easily inserted into the embedding groove. At the same time, the arc-shaped outward expansion reduces the friction and resistance during the insertion process, so that the H-beam can enter the guide block more smoothly and be correctly positioned at the desired position.

[0012] Preferably, a fan-shaped block is rotatably connected to one side of the guide block, and one end of the fan-shaped block is embedded in the corresponding groove of the web of the H beam. The fan-shaped block provides additional fixing and connecting functions, thereby enhancing the connection strength between the H beam and the fixing seat.

[0013] Preferably, the bottom of the bottom shell is fixedly connected to the top of the top shell by symmetrically arranged fastening bolts, so that the fastening bolts provide a method for further strengthening the connection between the bottom shell and the top shell after assembly is completed. The addition of fastening bolts not only improves the stability of the fixing seat, but also ensures the stability and safety of the H-beam during long-term use.

[0014] A synchronous fastening method for a multi-faceted synchronous fastening steel structure fixing seat comprises the following steps: A. Preparation stage: Determine the installation position of the fixing seat according to the design requirements of the steel structure, ensure that the bottom shell can be firmly fixed on the outside of the column, and fix the bottom shell at the specified height through the connection part and fixing bolts at the bottom of the bottom shell to adapt it to the size and installation requirements of the H beam; B. Preliminary positioning: Insert the web of the H-beam into the guide block groove at the bottom shell notch in an oblique manner. At the same time, ensure that the upper and lower flange plates of the H-beam are located on the upper and lower sides of the guide block respectively. Rotate the H-beam downward so that its bottom is aligned with the bottom of the bottom shell notch and the H-beam is horizontal. C. Synchronous locking: Slide the top shell down and over the outside of the bottom shell, so that the notches of the bottom shell and the top shell together buckle the H-beam. During the lowering process of the top shell, the extrusion blocks at the bottom of the connecting columns at the four corners will squeeze the corresponding extrusion slopes, guiding the positioning rods to slide. The positioning rods move closer to each other, pressing the bottom flange plate of the H-beam, and synchronously locking and positioning multiple H-beams around the bottom shell; D. Further reinforcement: After the top shell and bottom shell are completely fitted together, rotate the movable rod until it is perpendicular to the long rod, and slide the movable rod horizontally so that it is inserted into the gap between one end of the corresponding set of fixing bolts and the bottom shell. A T-shaped structure is formed between the movable rod and the long rod to further lock the top shell and bottom shell. Finally, the fastening bolts at the bottom of the bottom shell are used to further strengthen the connection between the bottom shell and the top shell to ensure the stability and safety of the fixing base.

[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention adopts a multi-faceted synchronous design. The fixing seat can simultaneously lock multiple H beams to ensure their position and stability in the steel structure. This synchronous fastening method effectively avoids the problem of overall structural instability caused by loosening or displacement of a single H beam.

[0016] 2. The fixing seat of the present invention adopts a variety of fastening mechanisms inside, such as positioning rods, extrusion blocks, movable rods, etc. These mechanisms work together to achieve a high-strength connection to the H-beam. This connection method not only enhances the connection strength between the H-beam and the column, but also improves the bearing capacity of the entire steel structure.

[0017] 3. The fan-shaped block design inside the guide block of the present invention and the T-shaped structure formed by the movable rod and the long rod effectively prevent the risk of the H-beam falling off when subjected to external force. This design ensures the safety and stability of the steel structure under extreme conditions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] The multi-faceted synchronously fastened steel structure fixing seat comprises a bottom shell 1 and a top shell 2; like Figures 1 to 7 As shown, the bottom shell 1 is fixedly connected to the outside of the column, and the top shell 2 is slidably sleeved on the outside of the bottom shell 1, and the top shell 2 is slidably connected to the outside of the column. Notches 3 are provided around the bottom shell 1 and the top shell 2. The notches 3 of the top shell 2 are aligned one by one with the notches 3 of the bottom shell 1, and the notches 3 of the top shell 2 and the notches 3 of the bottom shell 1 form H-beam insertion interfaces 4 in pairs. Guide blocks 5 are rotatably connected to the notches 3 inside the bottom shell 1, and embedding grooves 6 are provided at the centers of the guide blocks 5. The embedding grooves 6 are used to insert the webs of the H-beam. Positioning rods 7 are slidably connected to both sides of the notch 3 inside the bottom shell 1, and one end of the positioning rod 7 is provided with an extrusion inclined surface. Connecting columns 8 are fixedly connected to the four corners of the top shell 2, and the bottom ends of the connecting columns 8 are fixedly connected to extrusion blocks 9. The outer walls of both sides of the extrusion blocks 9 are respectively fitted with the corresponding extrusion inclined surfaces. During the assembly process, it is necessary to first insert one end of the column into the top shell 2 and the bottom shell 1 in sequence, ensuring that the top shell 2 is located at the top and the bottom shell 1 is located at the bottom. According to the height of the H-beam required to be assembled, the bottom shell 1 can be fixed to the outside of the column in advance. Then, slide the top shell 2 upward to open the space between the top shell 2 and the bottom shell 1, exposing the guide block 5 in the bottom shell 1. At this time, the H-beam on the corresponding side is inserted into the corresponding notch 3 of the bottom shell 1 in an oblique manner. During the insertion process, the web of the H-beam will be inserted into the embedding groove 6 of the guide block 5. At the same time, the upper and lower flange plates of the H-beam are respectively located on the upper and lower sides of the guide block 5. Then, rotate the H-beam downward so that its bottom is in contact with the bottom of the notch 3, so that the H-beam is in a horizontal state. After the H-beam is tilted and inserted into the notches 3 around the bottom shell 1 and rotated to a horizontal position, the top shell 2 is slid down and placed outside the bottom shell 1. At this point, the notches 3 of the bottom shell 1 and the top shell 2 jointly hold the H-beam. As the top shell 2 descends, the extrusion blocks 9 at the bottom of the connecting columns 8 at the four corners of the top shell 2 will press the corresponding extrusion slopes, guiding the positioning rods 7 to slide, so that the positioning rods 7 on both sides of the notch 3 approach each other, pressing the bottom flange plates of the H-beam, and synchronously locking and positioning the multiple H-beams around the bottom shell 1.

[0028] like Figures 1 to 7 As shown, a guiding slope is provided at the other end of the positioning rod 7, and the guiding slope enables the positioning rods 7 to press the bottom flange plate of the H beam more smoothly when approaching each other.

[0029] like Figures 1 to 7 As shown, symmetrical positioning blocks 10 are fixedly connected to the bottom of the notch 3 inside the bottom shell 1. The positioning blocks 10 are used to be respectively embedded in the waist-shaped holes symmetrically opened at the bottom of the H-beam. During the rotation of the H-beam, the H-beam will drive the guide block 5 to rotate, and the positioning blocks 10 will also gradually be embedded in the corresponding waist-shaped holes at the bottom of the H-beam to perform preliminary positioning of the H-beam.

[0030] like Figures 1 to 7 As shown, thin rods 11 are equidistantly fixedly connected to the bottom of the top shell 2, and the thin rods 11 are slidably inserted into the corresponding embedded grooves 6. The thin rods 11 are used to insert into the embedded grooves 6 to squeeze the H-beam and lock it. When the top shell 2 slides down, the thin rods 11 will be inserted into the corresponding embedded grooves 6, squeezing the H-beam so that the positioning block 10 can slide to one end of the waist-shaped hole of the H-beam, ensuring that the H-beam cannot slide slightly, and further positioning the H-beam.

[0031] like Figures 1 to 7 As shown, a connecting portion 12 extends downward from the bottom center of the bottom shell 1, and the connecting portion 12 is sleeved on the outside of the column. Two groups of fixing bolts 13 are symmetrically passed through the inside of the connecting portion 12. The fixing bolts 13 are used to fix the connecting portion 12 to the outside of the column. The bottom shell 1 is fixed to the outside of the column with the fixing bolts 13, which improves the convenience during assembly and ensures the stability and reliability of the fixing base.

[0032] like Figures 1 to 7 As shown, a long rod 14 is symmetrically fixedly connected to the bottom of the top shell 2. The long rod 14 passes through the bottom shell 1 and is fixedly connected to a sliding rod 15 at the end. A movable rod 16 is slidably connected to the outer side of the bottom end of the long rod 14. Sliding holes 17 are provided on both sides of the movable rod 16. The two ends of the sliding rod 15 are respectively slidably connected to the corresponding sliding holes 17. The long rod 14 is slidably inserted into the gap between one end of the corresponding set of fixing bolts 13 and the bottom shell 1; During the descending process of the top shell 2, the movable rod 16 at the bottom end of the long rod 14 will pass through the bottom shell 1. When the top shell 2 is completely fitted with the bottom shell 1, the movable rod 16 completely passes through the bottom shell 1, and the bottom end of the long rod 14 is also exposed outside the bottom shell 1. At this time, the movable rod 16 can be rotated to be perpendicular to the long rod 14, thereby sliding the movable rod 16 horizontally. In this way, the L-shape between the movable rod 16 and the long rod 14 is transformed into a T-shape, so that the long rod 14 cannot be pulled back from the bottom shell 1, further locking the top shell 2 and the bottom shell 1. At the same time, the horizontally sliding movable rod 16 can also be inserted into the gap between one end of a corresponding set of fixing bolts 13 and the bottom shell 1, limiting the rotation of this set of fixing bolts 13, preventing them from loosening, and reinforcing them.

[0033] like Figures 1 to 7 As shown, the opening of the embedding groove 6 of the guide block 5 is arranged in an arc-shaped outward expansion, which reduces the friction and resistance during the insertion process, so that the H-beam can enter the guide block 5 more smoothly and be positioned at the desired position.

[0034] like Figures 1 to 7 As shown, a sector block 18 is rotatably connected to one side of the guide block 5, and one end of the sector block 18 is embedded in the corresponding groove of the web of the H-beam. In the process of the H-beam driving the guide block 5 to rotate, the sector block 18 inside the guide block 5 will be restricted by the side wall of the inner cavity of the notch 3 of the bottom shell 1. Under the extrusion and guidance of the side wall of the notch 3, the inclined surface of one side of the sector block 18 will rotate into the embedding groove 6, so that the other side of the sector block 18 can be stuck in the groove on the surface of the web of the H-beam, thereby strengthening the fixation and enhancing the connection.

[0035] like Figures 1 to 7 As shown, the bottom of the bottom shell 1 is fixedly connected to the top of the top shell 2 by symmetrically arranged fastening bolts 19. The fastening bolts 19 further strengthen the connection between the bottom shell 1 and the top shell 2 after assembly is completed, ensuring the stability and safety of the H-beam during long-term use.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
