Embodiment Construction

[0048] like Figure 1 to Figure 12 As shown, for existing defects, the subject of protection of the present invention is as follows:

[0049] What is developed is an anti-seismic, self-aligning support, especially an ultra-thin support. Under the same anti-seismic performance, the size of the support in the height direction is compressed by at least half, and the anti-seismic performance is improved.

[0050] Based on the above description, the specific structure of this support is as follows:

[0051] It includes upper, middle and lower parts. The upper part 1 is used to connect with supported objects, such as bridges and beams, and has the ability of elasticity in the vertical direction. The middle part 2 has the ability to consume vibrations and impacts in three dimensions, and has the ability to automatically return to the center of the center. The lower part 3 is used for connecting with supporting beams and columns.

[0052]The upper part 1 is a square block structure...

Abstract

The invention discloses an engineering anti-seismic support used for solving the problem that an existing support is poor in anti-seismic performance. The support comprises an upper part, a middle part and a lower part. The middle part comprises a first sliding plate and a second sliding plate which are stacked from top to bottom, the first sliding plate is rotationally matched with the upper part, each edge of the lower surface of a wing part is provided with an elastic element, the first sliding plate is matched with the lower part through the second sliding plate, and a second arc-shaped toothed protrusion and a third arc-shaped toothed protrusion on the upper surface and the lower surface of the second sliding plate are perpendicular to each other. By means of the support, height is reduced by about 40% under the condition that bearing force and the anti-seismic performance are not changed, product flattening is achieved, and the support has more advantages in the bridge and building installation process.

Description

technical field [0001] The invention relates to a support widely used in the field of engineering technology, and is especially suitable for bridges, buildings and steel structures, specifically a support with a three-dimensional buffer function. Background technique [0002] In bridge engineering and prefabricated buildings, bearings are widely used. The main function of bearings is to resist earthquakes and reduce impact. [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 the structure or components from the seismic ground motion or support motion that may cause damage, cut off the transmission path of seismic energy, reduce the seismic force and energy input to the building stru...
