An Elastic Device Used in Building Seismic Settlement Joints

Abstract

The invention provides an elastic device used in anti-seismic settlement joints of buildings, the building includes a plurality of structural units, the anti-seismic settlement joints are between adjacent structural units, and the structures on both sides of the anti-seismic settlement joints The unit is provided with a first groove and a second groove corresponding to the position, the second groove is provided with a vertical chute, and the elastic device is provided with at least two sets in the horizontal direction in the shockproof settlement joint. , the elastic device includes a fixed part and a movable part, a spring is connected between the fixed part and the movable part, the fixed part is installed in the first groove, the movable part is located in the chute, and can Move up and down along the chute. The invention can make the adjacent structural units of the building obtain necessary lateral constraints during earthquakes, but at the same time does not affect the respective settlements of the adjacent structural units, and can adapt to different settlement differences; it can play the role of anti-seismic joints without Lost the function of the settlement joint.

Description

technical field [0001] The invention relates to the field of construction, in particular to an elastic device used in anti-seismic settlement joints of buildings. Background technique [0002] Settlement joints are an indispensable design content in hydraulic engineering and construction engineering. According to the actual situation, when the building requires seismic design, anti-seismic joints should also be set; when both settlement joints and anti-seismic joints need to be set, two joints are generally set together to reduce the number of joints in the entire building. It is called anti-seismic settlement joint. The function of anti-seismic settlement joints is: when uneven settlement or earthquake occurs in the building, each structural unit can change independently and freely, so as not to cause mutual restraint and extrusion. [0003] At present, for the anti-seismic settlement joints arranged in hydraulic structures such as sluices, pumping stations, and hydropowe...

AI Technical Summary

Problems solved by technology

Theoretically, the setting of anti-seismic settlement joints changes the stress units of the structure, and the building after the joints are divided into several structural units, and the structural units in the middle cannot transmit horizontal loads to both sides. Therefore, when an earthquake occurs, the seismic horizontal load cannot be transferred Transfer to the soil below the ground on both sides

In addition, when an earthquake occurs, because the vibration conditions of each structural unit are different, the anti-seismic settlement joints are easily crushed and broken, resulting in serious structural damage. failure due to compression

[0004] In major earthquakes such as the Wenchuan Earthquake and the Ludian Earthquake, a large number of seismic settlement joints of hydraulic structures suffered varying degrees of damage, which fully demonstrates that the current structure of seismic settlement joints is unreasonable, and there is a problem that horizontal earthquakes cannot be transmitted between structural units. load, and it is difficult to avoid the mutual extrusion and collision of the structures on both sides, which poses a great safety hazard
