Embodiment Construction

[0039] Such as Figure 1 to Figure 7 As shown, for existing defects, the subject of protection of the present invention is as follows:

[0040] The three-dimensional self-aligning seismic isolation and anti-seismic bearings for engineering are developed. The following is a detailed introduction to the three-dimensional self-aligning isolation and anti-seismic bearings for special projects:

[0041] The three-dimensional self-aligning seismic isolation and anti-seismic support for special engineering includes a first plate 1, a second plate 2 and a third plate 3 arranged from top to bottom.

[0042] Wherein, the first plate 1 adopts a steel plate with a thickness of at least 20 mm, and a first mounting part 11 is arranged on the upper surface of the first plate 1, and the two are connected by welding. , bridge beams and other components are connected, and a first socket board 12 and a first buffer assembly 13 are arranged on the lower surface of the first board 1 . There are ...

Abstract

The invention discloses an engineering three-dimensional aligning shock-isolation and anti-seismic support. The support comprises a first plate, a second plate and a third plate which are arranged in parallel from top to bottom. First plug boards and first buffering assemblies are arranged on the lower surface of the first plate, the lower surface of each first plug board is an arc-shaped face with the arch side downward, a steel ball is embedded in the arc-shaped face of each first plug board, the lowest ends of the steel balls are exposed out of the first plug boards, and the lower end faces of the first plug boards are in rolling fit with the second plate through the steel balls and are arc-shaped paths; first ball grooves are formed between every two first plug boards. The matching relation of the second plate and the third plate is similar to the preceding relation, safety pins and sealing sleeves are arranged. The three plates move relatively in an arc shape, the support has a certain aligning function and can meet the requirement for dynamic balance, vibration energy can be effectively consumed in the aligning process through conversion of gravitational potential energy, and the shock-reduction effect is remarkable.

Description

technical field [0001] The invention relates to an anti-seismic support used in the technical fields of construction and traffic bridges, specifically a three-dimensional self-aligning seismic isolation and anti-seismic support for engineering with excellent anti-seismic performance. Background technique [0002] The earthquake caused severe damage to various building structures and elevated bridges. Seismic isolation technology is a technology that has developed rapidly in the field of earthquake resistance in the past 30 years and has been continuously improved. It is currently mainly used in the fields of buildings and bridges. [0003] When the magnitude of the earthquake is large or the "hard resistance" of the structure is difficult to meet the expected seismic requirements due to some reasons, the use of seismic isolation technology to reduce the input seismic energy of the structure can achieve good results. The essential function of seismic isolation is to separate...
