Prestress-free self-resetting and energy consumption inhaul cable support

Abstract

The invention discloses a prestress-free self-resetting and energy consumption inhaul cable support. The prestress-free self-resetting and energy consumption inhaul cable support comprises a resettingmechanism, an energy consumption mechanism, a force-limited energy consumption mechanism, a high-strength steel cable and a sleeve; the resetting mechanism comprises a sliding end plate, a spring anda connecting rod; one end of the spring and the inner wall of the sleeve are connected and fixed, the other end of the spring is connected with the sliding end plate, one end of the connecting rod isanchored with the center of the sliding end plate, and the other end of the connecting rod penetrates through the fixed end of the spring; the energy consumption mechanism comprises a rotating shaft,rotating wheels, friction plates, chains and a cross connecting piece, wherein the rotating shaft and the sleeve are fixed, the friction plates are arranged on the two sides of the rotating wheels, the two chains are connected with the two rotating wheels correspondingly and connected through the two sides of the cross connecting piece, and the other two sides of the cross connecting piece are connected with the connecting rod and the high-strength steel cable correspondingly; and the force-limited energy consumption mechanism is a low-carbon steel connecting plate arranged inside the cross connecting piece, the low-carbon steel connecting plate and the cross connecting piece are fixed in a clamped connection mode, and the high-strength steel cable penetrates into the cross connecting piece to be anchored with the low-carbon steel connecting plate. The prestress-free self-resetting and energy consumption inhaul cable can achieve the self-resetting function without applying prestress.

Description

technical field [0001] The invention relates to a shock absorption device, in particular to a prestress-free self-reset energy-consuming cable support. Background technique [0002] As an efficient lateral force resistance system, the support frame is widely used in the field of engineering earthquake resistance. However, the traditional support frame system often produces large irrecoverable deformation after strong earthquakes, which seriously endangers the safety of buildings, and is difficult and expensive to repair. [0003] Self-resetting support is a relatively novel support form, which can effectively solve the problem that existing support structures are difficult to repair after earthquakes. However, the existing self-resetting supports mostly use prestress to realize the self-resetting function of the support, which has some shortcomings: (1) the application of prestress is cumbersome and difficult, and the tension control stress is not easy to accurately control...

However, the traditional bracing frame system often produces large unrecoverable deformation after strong earthquakes, which seriously endangers the safety of buildings, and repairs are difficult and expensive

[0003] Self-resetting support is a relatively novel support form, which can effectively solve the problem that the existing support structure is difficult to repair after an earthquake

However, the existing self-resetting supports mostly use prestress to realize the self-resetting function of the support, and there are some shortcomings: (1) the application of prestress is cumbersome and difficult, and the tension control stress is not easy to control accurately; (2) the loss of prestress is difficult to avoid, affecting (3) The requirements for prestressed materials are high, and fiber-reinforced composite materials are often used, which is expensive; (4) Anchorages often need to be specially designed and difficult to install; (5) Under the action of earthquakes exceeding the fortification intensity, there is no effective protection mechanism
