Embodiment 1

[0021] The invention provides an assembled beam-column lead extrusion type energy dissipation node, such as figure 1 As shown, it includes a precast concrete column 1 and a precast concrete beam 2; a steel plate 3 is preset on the outside of the precast concrete column 1, and a lead block 4 is arranged on the steel plate 3, and the precast concrete column 1 is fixedly connected to the precast concrete beam 2 through the steel plate 3. The lead block 4 is a rectangular block structure, two lead blocks 4 are arranged on the steel plate 3 , and the lead block 4 is located between the prefabricated concrete beam 2 and the steel plate 3 . The steel plate 3 and the prefabricated concrete beam 2 are fixed by riveting.

Embodiment 2

[0023] This embodiment is based on the structural changes and further improvements made on the basis of Embodiment 1. On the basis of Embodiment 1, such as figure 2 As shown, the lead block 4 is changed to a cuboid structure, and a lead block 4 is provided on the steel plate 3, so that the processing is more convenient and the force is more uniform. The lead block 4 is located between the precast concrete beam 2 and the steel plate 3 . The upper and lower ends of the steel plate 3 are respectively provided with a steel side plate 5, and the end of the precast concrete beam 2 close to the precast concrete column 1 is located between the two steel side plates 5, and the precast concrete beam 2 and the steel side plate 5 are respectively fixedly connected, The firmness of the connection between the precast concrete beam 2 and the precast concrete column 1 is further improved, which is safe and reliable.

Abstract

The invention discloses a fabricated beam-column lead extrusion type energy dissipation joint which comprises a precast concrete column and a precast concrete beam. A steel plate is prearranged on theouter side of the precast concrete column, lead blocks are arranged on the steel plate, and the precast concrete column is fixedly connected with the precast concrete beam through the steel plate. The fabricated beam-column lead extrusion type energy dissipation joint improves the reliability of dry connection of the fabricated beam and column, so that the joint has a certain energy dissipation capability, and the damage of a joint region is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of assembled beam-column connection, in particular to an assembled beam-column lead extrusion type energy dissipation node. Background technique [0002] Prefabricated concrete buildings refer to concrete structure buildings designed and constructed through on-site assembly, mainly based on factory-produced concrete prefabricated components. The assembly methods of components generally include on-site post-casting laminated layer concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting connection, welding, mechanical connection and lap connection of reserved holes. [0003] With the acceleration of the process of "construction industrialization and housing industrialization" in China, the continuous reduction of China's "demographic dividend" and the emergence of labor shortages in the construction industry, the trend of housing ind...
