The utility model relates to the technical field of building construction, especially a multi-beam frame structure, the multi-beam frame structure includes at least one first connecting beam and at least one second connecting beam, one of the first connecting beam and the second connecting beam is the prefabricated connecting piece, and the prefabricated connecting piece is configured to connect the first connecting beam and the second connecting beam. The main purpose of the utility model is to provide a multi-beam frame structure, which aims to reduce the assembly difficulty between the main beam and the secondary beam.

This invention discloses a high-strength precast cement power pole and its manufacturing method, relating to the fields of power engineering and communication infrastructure technology. The high-strength precast cement power pole and its manufacturing method include a pole body, a base plate fixedly connected to the bottom end of the pole body, reinforcing ribs uniformly fixedly connected to the base plate, the other end of each reinforcing rib fixedly connected to the pole body, and a pre-embedded pier with a frustum-shaped structure at the bottom end of the base plate. A connecting mechanism is provided between the base plate and the pre-embedded pier, and steel reinforcement is embedded inside the pole body. In this high-strength precast cement power pole and its manufacturing method, the pole body is the core load-bearing component, and the internal steel reinforcement enhances its flexural and tensile strength. The base plate at the bottom end of the pole body increases the contact area with the pre-embedded pier, dispersing pressure and preventing the pre-embedded pier from sinking into the soil. The reinforcing ribs strengthen the connection between the pole body and the base plate, reducing stress concentration and preventing loosening. The frustum-shaped pre-embedded pier conforms to the soil stress, and together with the connecting mechanism, ensures the stability of the power pole, meeting the long-term power transmission requirements.

The application discloses a steel pipe concrete shearing connecting piece with a constraint structure, which comprises a steel pipe concrete component for connecting a steel structure and a reinforced concrete structure and a tensile constraint structure thereof, the steel pipe concrete component comprises a steel pipe welded at one end with the steel structure, a high-strength and high-performance concrete filling layer poured in the steel pipe, and a steel cap embedded in the reinforced concrete structure and fixedly connected with the other end of the steel pipe, the constraint structure comprises a high-strength and high-performance concrete ring arranged on the outer periphery of the steel pipe, a tensile unit arranged on the outer periphery of the high-strength and high-performance concrete ring, and spiral reinforcement arranged around the tensile unit and the outer side of the steel pipe. The application can greatly improve the shearing strength and rigidity of the shearing connecting piece, ensure that the welding position is not a shearing weak position of the steel-concrete composite structure, effectively inhibit the splitting of the reinforced concrete and development thereof, and make the bearing capacity of each structure fully play; the shearing connecting piece has excellent structural toughness and can coordinate the deformation difference between the steel-concrete composite structures.
