Description

Technical Field

[0001] This utility model relates to the field of steel structure fastening technology, specifically to a steel structure fastener that can provide a stable connection. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. It has the advantages of high strength, light weight and fast construction speed.

[0003] Existing steel structure fasteners that can be securely connected are mostly optimized by designing them in a U-shape, allowing for rotation in two-dimensional space as well as 360° horizontal rotation. For example, Chinese utility model patent application number CN201720252871.1 discloses "Adjustable Direction Steel Structure Connector". In this device, there are a column, a connector, and a U-shaped clamping end. The lower end of the column is mounted on a base. A reinforcing rod is also installed on the column, with one end fixed to the column and the other end fixed to the base. The connector is installed on the upper end of the column and can rotate horizontally around the column. The upper end of the connector is connected to the U-shaped clamping end by a hinge. Its advantage is that the U-shaped clamping end can not only achieve rotation in two-dimensional space but also 360° horizontal rotation, which is convenient for fixing steel structures in different positions and directions. Its design is scientific.

[0004] While the aforementioned steel structure fasteners that can be securely connected have certain advantages in terms of enabling rotation in two-dimensional space and 360° rotation in the horizontal direction, they still have certain drawbacks: the fixing plates are usually fastened to the steel structure with screws. Before the steel structure is fastened, the personnel need to install the fixing plate bolts on the steel beams. Different fixing plates have different fixing forces. When installing larger fixing plates, personnel need to tighten the screws in multiple mounting holes, making the operation very cumbersome. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a steel structure fastener that can be stably connected, and has the following beneficial effects:

[0019] 1. This type of steel structure fastener that can be stably connected, by setting up connecting parts, allows personnel to select a panel of appropriate length according to the specifications of the steel beam, and bolt the panel to the steel beam, so that the reinforcing plate fits against the front end of the panel, increasing the thickness of the connecting parts and fasteners, and further enhancing the stability between the steel beams.

[0020] 2. This type of steel structure fastener, which can securely connect steel beams, uses a bolt mounting post and a tightening / loosening structure. When a person presses the pressing handle, the lower end of the tightening / loosening structure passes through the locking slot. Then, the person releases the pressure on the pressing handle, causing the ball bearing to move upward and gradually be pressed into the arc surface of the inner wall of the locking slot. This causes the lower end of the tightening / loosening structure to engage with the locking slot, thus securing the fastener firmly on the connector. This enhances the tightening force of the connector on the steel beam, allowing the steel beams to be securely connected, and making assembly and disassembly easy. Attached Figure Description

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.

[0030] Please see Figure 1-3A steel structure fastener capable of stable connection includes a steel beam 1, a connector 2, and a fastener 3. The connector 2 is connected to the outer end face of the steel beam 1 by screws and bolts. The fastener 3 is located on the front end face of the connector 2 and is inserted into the connector 2. The connector 2 includes a fitting port 21, a locking port 22, a panel 23, and mounting holes 24. The fitting port 21 and the panel 23 are an integral structure and are located at the front end face. The mounting holes 24 are welded to the four outer corners of the panel 23. The locking port 22 is provided below the fitting port 21. The panel 23 is bolted to the outer end face of the steel beam 1 by screws passing through the mounting holes 24. The front end face of the panel 23 fits against the rear end face of the fastener 3. The locking port 22 is inserted into the back of the fastener 3. The locking port 22 is in a through state and has an arc-shaped inner wall to facilitate better locking with the fastener 3.

[0031] Please see Figure 4-5 A steel structure fastener that can be stably connected includes a reinforcing plate 31, a bolt mounting post 32, a tightening structure 33, and a fitting seat 34. The bolt mounting post 32 passes through the reinforcing plate 31 and is bolted to the reinforcing plate 31. The tightening structure 33 passes through the interior of the bolt mounting post 32 and is inserted into it. The fitting seat 34 is welded to the lower end face of the reinforcing plate 31 and is pressed into the fitting opening 21. The reinforcing plate 31 is attached to the front of the panel 23.

[0032] Please see Figure 6-7 A steel structure fastener capable of stable connection includes a bolt-mounted post 32 comprising a limiting cavity q1, a connecting post q2, and an embedded block q3. The connecting post q2 is welded to the lower end of the limiting cavity q1, and the embedded block q3 is welded to the lower end of the connecting post q2. The tensioning structure 33 comprises a pressing handle a1, a spring a2, a ball a3, a magnetic block a4, and a through block a5. The spring a2 is wound around the outer periphery of the pressing handle a1. The magnetic block a4 is fixedly connected between the lower end of the pressing handle a1 and the upper end of the through block a5. The ball a3 is disposed on the left and right sides of the magnetic block a4. The connecting post q2 penetrates and is bolted to the reinforcing plate 31. The pressing handle a1 passes through the interior of the limiting cavity q1, the connecting post q2, and the embedded block q3. The ball a3 moves above the embedded block q3 and engages with the locking slot 22 through the embedded block q3. The ball a3 is magnetic and has two components, which move on the left and right sides of the magnetic block a4, respectively.

[0033] In summary, when connecting the steel beams 1 between plates, a secure connection is achieved through the cooperation of connector 2 and fastener 3. With connector 2 in place, personnel select a panel 23 of appropriate length according to the specifications of the steel beams 1. Screws pass through the mounting holes 24, and the panel 23 is bolted to the steel beams 1, creating a bolted connection between the steel beams 1. The engagement of the fitting port 21 and the fitting seat 34 allows the reinforcing plate 31 to adhere to the front end face of the panel 23, increasing the thickness of connector 2 and fastener 3 and further enhancing the stability between the steel beams 1. Through the cooperation of bolt mounting post 32 and tightening structure 33, personnel press the pressing handle a1, and the magnetic block a4 and the through block a5 move accordingly. The fastener moves downwards along the inner side of the bolt mounting post 32, and the magnetic block a4 retracts into the inner side of the embedded block q3, making it easier for personnel to hold the entire fastener 3 and align it with the connector 2. The lower end of the tightening structure 33 is then inserted into the locking slot 22. Then, the personnel release the pressure on the pressing handle a1, and the pressing handle a1 is reset upwards under the elastic force of the spring a2, causing the ball a3 to move upwards and gradually be pressed into the arc surface of the inner wall of the locking slot 22. This allows the lower end of the tightening structure 33 to form a locking action with the locking slot 22, thus securing the fastener 3 firmly on the connector 2. This enhances the tightening force of the connector 2 on the steel beam 1, allowing the steel beams 1 to be securely connected and making disassembly and assembly easy.
