Problems solved by technology

[0002] With the development of society, my country's demand for prefabricated reinforced concrete frames is increasing. This prefabricated frame has the characteristics of simple structure, easy construction, high strength and rigidity, but its energy dissipation capacity is very poor, which makes it resistant to earthquakes. The capacity is very weak, and when the earthquake comes, it is prone to large plastic deformation and damage, which seriously threatens people's lives and property safety.

Embodiment 1

[0025] Such as Figure 1-Figure 3 As shown, an energy-dissipating device with active adjustment and self-resetting capabilities includes a mixed-reinforced frame and an energy-dissipating mechanism 5 based on magnetorheological elastomers. The mixed-reinforced frame is fixed on the frame by the frame bottom beam 1 and The frame body 3 on the bottom beam is composed of a frame body 3 made of FRP bars and steel bars mixed with reinforcement. The reinforcement method is to distribute the FRP bars on the outside of the columns of the frame body 3 and the inside of the columns Ordinary steel bars are set, and the columns of the frame main body 3 adopt the method of mixed reinforcement, which can effectively improve the elasticity of the frame and make the frame have a good self-resetting ability. The reinforcement of the top beam of the frame main body 3 and the frame bottom beam 1 are uniform For ordinary steel bars. The frame bottom beam 1 is provided with a strain sensor 6, a c...

Embodiment 2

[0032] The construction method of an energy-consuming device with active adjustment and self-resetting capabilities includes the following steps:

[0033] (1) First pour the frame main body 3 and the frame bottom beam 1. The frame main body 3 is made of mixed reinforcement of FRP bars and steel bars. The inner side of the column of the frame main body is made of ordinary steel bars 19, and the outer side of the ordinary steel bars is set with FRP. Rib 20, the top beam and the frame bottom beam of the frame main body are reinforced with pure steel bars, and then the columns of the frame main body, the top beam and the frame bottom beam of the frame main body are poured with concrete respectively. During the pouring process, the strain sensor is pre-embedded in the frame bottom beam, and the strain sensor is led out with wires, and the controller and power supply installation holes are reserved on the frame bottom beam;

[0034] (2), hoist the pillars and top beams of the prefab...

Abstract

The invention relates to an energy-dissipating device with active adjustment and self-resetting capabilities and a construction method thereof, comprising a mixed-reinforced frame and an energy-dissipating mechanism based on magnetorheological elastomers, and the mixed-reinforced frame is fixed by frame bottom beams and The main body of the frame is formed on the bottom beam of the frame. The main body of the frame is made of mixed reinforcement of FRP bars and steel bars. The strain sensor, controller and power supply are arranged in the bottom beam of the frame. The angle between the bottom beam of the frame and the main body of the frame The inner side is fixed with a first hinged plate, and the inner side of the top middle of the frame main body is fixed with a second hinged plate, and the middle position of the second hinged plate and the first hinged plate is provided with an energy dissipation mechanism based on a magneto-rheological elastomer. The plate is fixedly connected to the energy dissipation mechanism based on the magnetorheological elastomer through the second support plate, and the energy dissipation mechanism based on the magnetorheological elastomer is fixedly connected to the first hinge plate through the first support plate. The invention has strong self-resetting ability and energy consumption ability, and ensures the safety of buildings after earthquakes.
