Abstract

The invention discloses an assembling reinforcing structure for energy consumption of an external contact surface of an existing structure. The assembling reinforcing structure comprises a reinforcingstructure unit, wherein the reinforcing structure unit comprises a vertical prefabricated column and a transverse prefabricated beam; the vertical prefabricated column and the transverse prefabricated beam are detachably connected to form a frame; a prefabricated support and a prefabricated angle brace are arranged in the frame; one end of the prefabricated support is detachably connected with the vertical prefabricated column; the other end of the prefabricated support is detachably connected with the transverse prefabricated beam; and the connecting part of the vertical prefabricated columnand the transverse prefabricated beam and the middle of the prefabricated support are detachably connected with the prefabricated angle brace. The assembling reinforcing structure enhances the resistant-lateral rigidity, improves the shock resistance and also can improve the stressed state and the deformation mode of the original structure to enable the structure to form a more reasonable damageyield mechanism.

Description

technical field [0001] The invention relates to the reinforcement of an additional substructure, in particular to an assembled reinforcement structure for energy consumption on the peripheral contact surface of an existing structure. Background technique [0002] The overall reinforcement of the additional substructure, that is, using the cooperative work of the additional overall substructure and the original structure, changing the structural system of the original structure, transferring the damage to the additional substructure, thereby changing the stress state and deformation mode of the original structure, and strengthening the overall structure Seismic capacity, thereby alleviating the overall seismic demand, is a method of strengthening a structural system. [0003] However, most of the existing reinforcement methods are limited to reinforcement at the component level, such as enlarging the cross-section of the component, attaching steel plates, etc., which virtuall...
