Embodiment Construction

[0016] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be further described in detail with reference to the accompanying drawings. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] Please see Figure 1 to Figure 4 , The present invention provides a built-in damping beam member with seismic and self-healing properties, which includes concrete 5, built-in viscous damping geotextile 6, bent steel bars 7, stirrups 8, and longitudinal bars 9. The 6 layers of the built-in viscous damping geotextile are woven geotextiles, and the inside is crisscrossed PVC hoses, which are filled with viscous damping; the overall thickness of the built-in viscous damping geotextile 6 is 1.5~2cm.

[0018] The internally criss-crossed PVC hose includes a longitudinal PVC hose ...

Abstract

The invention discloses a built-in damping beam member with the anti-seismic and self-healing performance. The built-in damping beam member comprises concrete, a built-in viscous damping geotechnical cloth, a bent bar, a stirrup and a longitudinal bar. The built-in viscous damping geotechnical cloth is a knitted geotechnical cloth, and PVC hoses are arranged inside the built-in viscous damping geotechnical cloth in a criss-cross mode and filled with viscous damping; firstly, the built-in viscous damping geotechnical cloth is stuck to the lower surface of the bent bar, then, the built-in viscous damping geotechnical cloth wraps the outer surface of a steel bar cage bound by the stirrup, and the built-in viscous damping geotechnical cloth and the longitudinal bar are adhesively connected through an adhesive; finally, the concrete is poured, so that a whole is formed. The member has the certain self-healing performance, the shear strength and integrity of a beam are enhanced, brittle failure can be effectively avoided, and meanwhile the anti-seismic performance is enhanced due to the energy dissipation capability of the built-in damping.

Description

Technical field [0001] The invention belongs to the technical field of building structures, and specifically relates to a beam component with built-in viscous damping geotextile. Background technique [0002] Energy dissipation and shock absorption technology is to design some components in the structure as energy-consuming components, or to install energy-consuming components in certain parts of the structure. At present, a more effective way of energy dissipation and shock absorption is to install viscous dampers. Viscous dampers are widely used in civil engineering as an energy dissipation device without external energy input. However, because it is usually installed outside the structure, it is inevitably affected by temperature changes, chemical corrosion, etc., which greatly reduces its service life. As one of the main parts of the structure, the built-in damping can affect the beam when an earthquake occurs. Very good protection. [0003] As a multifunctional composite ma...
