Description

High-elastic vibration reduction partition keel structure Technical Field The utility model relates to the technical field of building keels, in particular to a high-elastic vibration reduction partition keel structure. Background In civil buildings, the partition wall is used as a key construction part, and the design of the partition wall is required to strictly follow multiple specifications so as to ensure the overall performance of the building and the safety and comfort of residents. The primary consideration is fire resistance, and the partition wall must be capable of effectively blocking fire spreading within a specified time to reach the corresponding fire rating standard. Secondly, the sound insulation effect is also important, and particularly, a private space such as a bedroom, a toilet and the like needs to have good sound insulation capability so as to maintain the calm of the living environment. In the aspect of bearing, the partition wall needs to bear the load of the area where the partition wall is positioned, so that the safety and stability of the building under the extreme conditions such as earthquake are ensured.
