Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a bracket for installing steel secondary beams. Background Technology

[0002] In steel structures, secondary steel beams are secondary load-bearing components erected above the main beams. They are typically arranged perpendicularly or obliquely to the main beams, forming the building's horizontal load-bearing system. The main function of secondary beams is to effectively transfer loads from floors, roofs, or other upper structures to the main beams, which then transfer the loads to vertical load-bearing structures such as columns and walls, ultimately leading to the foundation. This layered load transfer mechanism not only optimizes the load distribution path but also significantly improves the overall stability and load-bearing efficiency of the structure.

[0003] In design, the cross-sectional dimensions of secondary beams are usually smaller than those of main beams, but their spacing and number must be determined comprehensively based on the floor slab span, load magnitude, and the load-bearing capacity of the main beams. By rationally setting secondary beams, the calculated span of the floor slab can be reduced, and the floor slab thickness can be decreased, thereby saving material costs and reducing the structural self-weight. In addition, secondary beams can enhance the spatial stiffness of the structure, resist deformation caused by horizontal loads (such as wind loads or seismic action), and provide lateral support to the main beams, preventing the main beams from becoming unstable.

[0004] Currently, the installation of steel secondary beams and main beams mostly adopts the connection method of opening through holes in the middle of the main beam. That is, firstly, through holes are opened on the web or flange of the main beam, and then the connecting plate at the end of the secondary beam is fastened to the main beam with high-strength bolts. This traditional connection method is simple in structure and convenient in construction.

[0005] However, in practical applications, opening holes in the main beam will weaken its cross-sectional strength, especially under repeated loading, stress concentration is likely to occur around the hole; and the connection nodes rely solely on bolts for shear force transmission, resulting in limited rotational stiffness of the nodes, which is not conducive to improving the overall stiffness of the structure. Utility Model Content

[0006] The purpose of this invention is to provide a bracket for installing steel secondary beams. Through a triangular stabilizing system composed of a U-shaped support frame and an inclined connecting frame, and fixed with a support plate, the connection strength and overall stability are improved. The built-in inclined bracing plate forms a multi-triangular reinforcement structure, effectively enhancing bending and shear resistance, resulting in a stable and reliable structure with strong bending and shear resistance.

[0007] To achieve the above objectives, this utility model provides a bracket for installing a steel secondary beam, including a steel main beam and a steel secondary beam, and a support plate disposed at the bottom of the steel main beam. A support frame is provided at the connection between the steel main beam and the steel secondary beam. The top side of the support frame is connected to the steel main beam and the steel secondary beam through a first connector, and the bottom side of the support frame and the support plate are connected to the steel main beam and the steel secondary beam through the first connector.

[0008] Two inclined connecting frames are symmetrically arranged between the main steel beam and the secondary steel beam. The two ends of the connecting frames are connected to the main steel beam and the secondary steel beam respectively through second connecting members.

[0009] The above technical solution connects the U-shaped sections of the secondary steel beams and the main steel beams. A U-shaped support frame is placed at the connection point between the main and secondary steel beams, allowing the support plate to fit against the bottom of the main steel beam. The support plate and support frame are then bolted to the bottom of the main steel beam, ensuring its horizontal stability. The top side of the support frame is also bolted to the main and secondary steel beams to improve overall stability. An inclined connecting frame is installed between the main and secondary steel beams, with bolts at both ends fixing it to the main and secondary steel beams. This supports the secondary steel beams while forming a triangular stabilizing system, ensuring the strength and stability of the connection node.

[0010] The support frame is U-shaped, and the connecting frame is hollow.

[0011] The above technical solution involves hollow structures on the inner sides of both the support frame and the connecting frame, reducing weight and achieving lightweighting.

[0012] The support frame has multiple first diagonal bracing plates symmetrically fixed on its inner side, and the connecting frame has multiple second diagonal bracing plates uniformly fixed on its inner side.

[0013] Through the above technical solution, the multi-triangular structure formed by the first and second diagonal bracing plates enhances the bending and shear resistance of the support frame and connecting frame structure.

[0014] The steel main beam has multiple stiffening plates uniformly fixed inside its U-shaped groove.

[0015] The above technical solution involves uniformly welding stiffening plates at the U-shaped groove of the steel main beam to enhance the local stiffness of the steel main beam and prevent deformation.

[0016] The secondary steel beam has two symmetrically fixed positioning protrusions on the side near the main steel beam, and the main steel beam has a positioning groove on the side near the secondary steel beam. The positioning protrusions and the corresponding positioning grooves are inserted into each other.

[0017] The above technical solution involves the positioning protrusion and the corresponding positioning groove engaging to ensure the accuracy of the steel secondary beam installation position.

[0018] The secondary steel beam has a protruding part formed in the middle and on the side close to the main steel beam, and the protruding part can be inserted into the U-shaped groove of the main steel beam.

[0019] Through the above technical solution, the protruding part in the middle of the secondary steel beam is inserted into the U-shaped groove of the main steel beam, which further restricts displacement, improves the docking accuracy, and also plays a supporting role.

[0020] Wherein, the first connecting member is the first bolt, and the second connecting member is the second bolt.

[0021] The above technical solution uses bolts as connectors, which makes disassembly and assembly simple, and the connection is stable and reliable, thus ensuring the stability of the overall structure of the support.

[0022] This utility model discloses a bracket for installing steel secondary beams. Through a triangular stabilizing system composed of a U-shaped support frame and an inclined connecting frame, and fixed with a support plate, it enhances connection strength and overall stability. The built-in inclined bracing plate forms a multi-triangular reinforcement structure, effectively enhancing bending and shear resistance, resulting in a stable and reliable structure with strong bending and shear resistance.
