Mutual pull and traction type self-resetting reinforced concrete frame column base joint

Abstract

The invention belongs to the technical field of constructional engineering equipment, and particularly relates to a mutual pull and traction type self-resetting reinforced concrete frame column base joint comprising a concrete pile (1) and a concrete foundation (2). The mutual pull and traction type self-resetting reinforced concrete frame column base joint is characterized in that the lower ends of a first anchorage device (5) and a second anchorage device (6) are connected with a first steel strand (7), a second steel strand (8), a third steel strand (9) and a fourth steel strand (10) respectively, the first steel strand (7), the second steel strand (8), the third steel strand (9) and the fourth steel strand (10) are arranged in a mutually opposite manner and are dragged through fixed pulleys (11) on a top face steel plate (4); and a protective cover (12) covers the fixed pulleys (11). The mutual pull and traction type self-resetting reinforced concrete frame column base joint reduces the collapsing force of an earthquake greatly and achieves the effects that the structure is stable under a small earthquake, the structure deforms greatly but is not destroyed and under a violent earthquake and restores after the violent earthquake.

Description

technical field [0001] The invention belongs to the technical field of construction engineering equipment, and in particular relates to a mutual pull traction type self-resetting reinforced concrete frame column foot node. Background technique [0002] When an earthquake occurs, the concrete layer of the building floor will peel off due to the vibration, which will reduce the bearing capacity of the floor, and finally cause the entire concrete floor to break, resulting in the collapse of the entire floor. The traditional method is to pour a steel member into the concrete. However, the traditional Due to the simple structure of steel components, although it can increase the bearing capacity of the entire floor, when an earthquake occurs, the concrete layer is only wrapped outside the steel components, and the concrete layer is relatively brittle, so it is easy to leave only the steel components after peeling off. , and the compressive capacity of the entire steel member will ...
