Elastic device used in quakeproof settlement joint of building

Abstract

The invention provides an elastic device used in a quakeproof settlement joint of a building. The building comprises a plurality of structure units, wherein the quakeproof settlement joint is arranged between the adjacent structure units; a first groove and a second groove in corresponding positions are formed in the structure units arranged at two sides of the quakeproof settlement joint; a vertical slide slot is formed in the second groove; two sets of elastic devices are at least arranged in the quakeproof settlement joint in the horizontal direction; each elastic device comprises a fixed part and a movable part; a spring is connected between each fixed part and the corresponding movable part; each fixed part is arranged in the first groove; and each movable part is positioned in the slide slot and can vertically slide along the slide slot. The elastic device has the advantages that the adjacent structure units of the building can obtain necessary lateral restraint during the earthquake, and meanwhile, the respective settlement of the adjacent structure units cannot be influenced, so that the elastic device can adapt to different settlement differences; and both the effect of a quakeproof joint and the function of the settlement joint can be achieved.

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
