Description

Technical Field

[0001] This utility model relates to the field of building steel structure connection technology, and specifically to a building steel structure connector. Background Technology

[0002] Steel structure is a type of building structure that uses steel as its primary load-bearing material. Due to its high strength, lightweight, good toughness, plasticity, and ease of processing, steel is widely used in modern construction. Steel structures can be used in various types of buildings and structures, including but not limited to high-rise buildings, bridges, industrial plants, and stadiums.

[0003] Application number CN202421741992.9 discloses a steel structure connector for buildings, comprising: a vertical plate with a top plate perpendicular to it; a support plate with an upward-facing opening mounted on the vertical plate, the support plate and the top plate being located on opposite sides of the vertical plate; the support plate includes a horizontally arranged bottom wall with vertically arranged side walls connected to both ends, the side walls of the support plate being a certain distance from the side edge of the vertical plate; a first connecting hole is provided on the vertical plate, located between the side wall of the support plate and the side edge of the vertical plate; a slot is provided on the vertical plate, with a locking strip protruding towards one side of the support plate embedded in the slot; the upper end of the locking strip is flush with the vertical plate and fixedly connected to it, the lower end of the locking strip protruding from the vertical plate; and a flared opening is provided on the side wall of the support plate, located at the upper end of the side wall of the support plate. This connector facilitates the connection and fixing of steel structures and makes installation more convenient.

[0004] However, this connector relies solely on bolts to connect the two steel beams. Since the building structure will be subjected to dynamic loads for a long time, such as wind, earthquakes, and vibrations caused by the activities of people and equipment, the bolt connection is prone to loosening due to repeated stress. Once the bolts loosen, the tightness of the connection between the steel beams will decrease, which will lead to the destruction of the stability of the entire steel structure. In severe cases, it may even cause local deformation or overall collapse of the structure, which greatly threatens the safety of the building. Therefore, a new type of steel structure connector is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a building steel structure connector that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A building steel structure connector includes an upright plate, which is L-shaped. One side of the upright plate is fixedly connected to one end of a support plate. The support plate has a slot inside for inserting a second connecting steel beam and a connecting block. The support plate and the second connecting steel beam are fixedly connected by bolts, and the connecting block is fixedly connected to one end of the second connecting steel beam.

[0008] The vertical end face of the upright plate is provided with a first welding groove, and the four sides of the support plate are provided with a second welding groove. The first welding groove and the second welding groove are internally connected. The horizontal end face of the upright plate is attached to and fixedly connected to the top surface of the first connecting steel beam by bolts. The vertical end face of the upright plate is attached to and fixedly connected to one side of the first connecting steel beam by bolts.

[0009] By adopting the above technical solution, the second steel beam is precisely inserted through the slot, the connecting block and the connecting groove cooperate to complete the initial docking, the trapezoidal limit block is automatically locked under the action of the spring to form a mechanical anti-disengagement lock, and then the support plate and the second connecting steel beam and the upright plate and the first connecting steel beam are double fixed by bolts. Finally, the weld is reinforced by the connecting welding groove, thereby strengthening the connection stability between the steel structures.

[0010] Specifically, a connecting groove is provided on one side of the first connecting steel beam, and the connecting groove is used for the installation and insertion of the connecting block.

[0011] Specifically, mounting slots are provided on both opposite sides of the connecting block, and the mounting slots are used for the movable installation of the limiting block. The limiting block is arranged in a trapezoidal structure.

[0012] By adopting the above technical solution, when the connecting block is inserted into the connecting groove, the trapezoidal limiting block is squeezed by the inner wall of the connecting groove, forcing the limiting block to retract into the installation groove; once the connecting block is fully inserted, the limiting block automatically pops out after the external force disappears, and its trapezoidal horizontal surface is stuck in the inner wall of the first connecting steel beam, playing a limiting role, preventing the connecting block from coming out in the opposite direction, and ensuring the connection stability between the second connecting steel beam and the first connecting steel beam.

[0013] Specifically, one end of the limiting block is fixedly connected to one end of the spring, and there are two springs. The other ends of the two springs are fixedly connected to the inner wall of the mounting groove.

[0014] By adopting the above technical solution, the spring provides elastic force and stores energy when the limiting block is squeezed back into the mounting groove; when the connecting block is fully inserted into the connecting groove, the spring releases energy and pushes the limiting block out of the mounting groove.

[0015] Specifically, limiting plates are fixedly connected to the opposite sides of the limiting block, and the limiting plates are installed inside the mounting groove for limiting.

[0016] By adopting the above technical solution, the limiting plate restricts the movement range of the limiting block in the mounting groove, preventing the limiting block from completely detaching from the mounting groove when it pops out or retracts.

[0017] The beneficial effects of this utility model are:

[0018] The steel structure connector of this utility model guides the precise insertion of the second steel beam through a slot. The connecting block and the connecting groove cooperate to complete the initial docking. The trapezoidal limiting block automatically locks under the action of the spring, forming a mechanical anti-disengagement lock. Subsequently, the support plate and the second connecting steel beam and the upright plate and the first connecting steel beam are double fixed by bolts. Finally, the weld is reinforced by a connecting welding groove, thereby enhancing the connection stability between the steel structures. Attached Figure Description

The vertical end face of the upright plate 3 is attached and fixedly connected to one side of the first connecting steel beam 1 by bolts.

[0027] In use, the L-shaped structure of the upright plate 3 facilitates the simultaneous contact of its horizontal and vertical end faces with the top surface and one side of the first connecting steel beam 1, and is initially fixed by bolts; the slot 9 of the support plate 5 is used to guide the insertion of the second connecting steel beam 6 and the connecting block 7, and after insertion, the support plate 5 is fixed to the second connecting steel beam 6 by bolts; the interconnected design of the first welding groove 2 and the second welding groove 4 provides a channel for subsequent welding operations, ensuring that the welding mechanism can reinforce the contact area of ​​the first connecting steel beam 1 and the second connecting steel beam 6 from here, so as to achieve a stable connection of the steel structure.

[0028] It should be noted that bolt holes are provided on both sides of the support plate 5 for bolts to pass through, and bolt holes are provided on both the horizontal and vertical end faces of the upright plate 3 for bolts to pass through.

[0029] The present invention also includes a connecting groove 10 provided on one side of the first connecting steel beam 1, the connecting groove 10 being used for the installation and insertion of the connecting block 7.

[0030] The present invention also includes that the connecting block 7 has mounting grooves 11 on both opposite sides, the mounting grooves 11 being used for the movable installation of the limiting block 8, and the limiting block 8 being arranged in a trapezoidal structure.

[0031] During use, when the connecting block 7 is inserted into the connecting groove 10, the trapezoidal limiting block 8 is squeezed by the inner wall of the connecting groove 10, forcing the limiting block 8 to retract into the mounting groove 11; once the connecting block 7 is fully inserted, the limiting block 8 automatically pops out after the external force disappears, and its trapezoidal horizontal surface is stuck in the inner wall of the first connecting steel beam 1, which plays a limiting role, preventing the connecting block 7 from coming out in the opposite direction, and ensuring the connection stability between the second connecting steel beam 6 and the first connecting steel beam 1.

[0032] This utility model also includes that one end of the limiting block 8 is fixedly connected to one end of the spring 13, and two springs 13 are provided, with the other ends of the two springs 13 fixedly connected to the inner wall of the mounting groove 11.

During the insertion of the connecting block 7 into the connecting groove 10, it will press the limiting block 8, pushing the limiting block 8 into the mounting groove 11, until... When the connecting block 7 is fully inserted into the interior of the second connecting steel beam 1, the spring 13 will push out the limiting block 8. At this time, the limiting block 8 will be stuck inside the second connecting steel beam 1, thereby limiting the first connecting steel beam 6. Then, the upright plate 3 is fixedly connected to the first connecting steel beam 1 and the support plate 5 is fixedly connected to the second connecting steel beam 6 by bolts. Finally, the four sides of the second connecting steel beam 6 are welded to one side of the first connecting steel beam 1 from the junction of the first welding groove 2 and the second welding groove 4 by a welding mechanism, thereby realizing the fixed connection of the steel structure.
