Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a building vibration isolation joint structural node structure. Background Art
[0002] Building vibration isolation joints, also known as expansion joints or settlement joints, are a structural measure in buildings used to cope with the deformation and stress caused by factors such as temperature changes, uneven foundation settlement, and earthquakes.
[0003] Isolation joints divide a building into several independent parts, allowing each part to expand and settle freely, thus avoiding cracks and structural damage.
[0004] The main functions of vibration isolation joints:
[0005] Temperature deformation: Concrete and other building materials will expand and contract when the temperature changes. Isolation joints can allow the building to expand and contract freely when the temperature changes, avoiding the generation of temperature stress;
[0006] Foundation settlement: When the foundation settles unevenly, vibration isolation joints can prevent cracks in the building due to uneven settlement;
[0007] Earthquake effect: During an earthquake, buildings will be subjected to severe vibrations. Vibration isolation joints can provide a certain degree of buffering and isolation, reducing the damage caused by the earthquake to the building.
[0008] In order to further increase the amount of underground earth and rock excavation and facilitate the inspection and maintenance of the vibration isolation joint, it is necessary to design a node structure based on the vibration isolation joint structure between the first floor and the basement, so that it can meet the requirements of vibration isolation for the above-ground building but not for the underground structure.
