Description

A building anti-seismic and vibration-reducing device

technical field

The invention relates to the technical field of buildings, in particular to a building anti-seismic and vibration-damping device.

Background technique

Architectural structure refers to a space force system made of building materials to bear various loads or functions in buildings (including structures) to act as a skeleton. The building structure can be divided into concrete due to the different building materials used. Structure, masonry structure, steel structure, light steel structure, wood structure and composite structure, etc. House structure generally refers to the load-bearing structure and enclosure structure of the building. Before the house is built, according to the number of floors, The structure type is determined by the cost and construction. The durability, earthquake resistance, safety and space performance of houses of various structures are different. There are mainly reinforced concrete frame structures, shear wall structures, frame shear wall structures, Frame cylinder structure and cylinder structure, frame cylinder structure and cylinder structure are used in super high-rise building structures. The cast-in-place reinforced concrete structure frame structure is generally composed of beams, slabs and columns. It is characterized by flexible layout of the frame structure and has The larger indoor space is more convenient to use, and most of the floor slabs of the frame structure are cast-in-place reinforced concrete slabs.

According to the Chinese patent number, a building anti-seismic and vibration-reducing bearing is proposed, which proposes that with the rapid development of the national economy, rail transit has quickly become a city due to its advantages of convenience, speed, punctuality, energy saving and effective relief of ground traffic congestion The development of traffic construction is a hotspot, but vibration and noise pollution will also have a certain negative impact on buildings along the line. The buildings along the line must also consider the environmental pollution caused by vibration and noise while meeting the corresponding national seismic code design. The application cost is lower than other building vibration reduction schemes. The combination of earthquake resistance, vibration reduction and noise reduction simplifies the process, saves construction costs and material use costs, and can solve the problem of secondary structural noise in buildings .

Although people have gradually realized the importance of earthquake resistance in the process of building construction, the effect of earthquake resistance on high-rise buildings is not good.
