Description
Technical Field
[0001] The utility model relates to the technical field of building seismic isolation joints, in particular to a sealing joint structure for building seismic isolation joints. Background Art
[0002] Seismic isolation joints are a special design in buildings, the main purpose of which is to reduce or avoid earthquake damage when an earthquake occurs. Seismic isolation joints are in the horizontal direction. When seismic waves are transmitted to the foundation of the building, the frequency and intensity of the seismic waves are changed at the seismic isolation joints due to the action of rubber bearings, dampers and other components at the seismic isolation joints. The energy during the earthquake is converted and released at the seismic isolation joints, thereby reducing damage to the building.
[0003] The sealing structure of the seismic isolation joint of the building is to ensure that the seismic isolation joint can work effectively during an earthquake, while preventing damage from external factors such as moisture penetration and mechanical damage. The design of the sealing structure should meet certain requirements for sealing performance, elasticity and durability. First of all, the selection of sealing materials is the key. Commonly used sealing materials include polyurethane, silicone, etc. These materials have good sealing performance, elasticity and anti-aging properties, which can ensure that the seismic isolation joint will not fail due to aging or deformation of the material during an earthquake. Secondly, the construction of the sealing material is also an important link. The construction should be carried out after the concrete base bed is fully hardened to ensure good bonding between the sealing material and the base bed. Clean the sealing gap to ensure that the gap is clean and free of debris, then fill the sealing material into the gap and fully compact it to ensure close contact and firm bonding between the sealing material and the concrete base bed.
[0004] When existing seismic isolation joints are installed, seismic isolation joints are left between the building and the foundation. The building is protected from shock by the seismic isolation joints, and the seismic isolation joints are protected by sealing structures, thereby reducing moisture penetration and damage to the seismic isolation joints. However, existing seismic isolation joint sealing structures usually adopt a fixed structure when protecting the seismic joints, so that when the seismic isolation joints are manually inspected regularly, the sealing joints need to be reinstalled, which makes manual inspection inconvenient and increases the difficulty of inspecting the seismic isolation joints. Utility Model Content
