Problems solved by technology

However, under this structure, there are no partition measures outside the shock absorbing device. When pouring concrete, the shock absorbing device is also fixed in the concrete, so the shock absorbing effect is greatly reduced, and it is still difficult to meet the national earthquake resistance requirements. Both performance and safety could be improved

Abstract

The invention discloses a building pile foundation. The building pile foundation comprises an upper pile foundation body, a lower pile foundation body and a vibration absorption device, wherein the vibration absorption device is matched with the upper pile foundation body and the lower pile foundation body. The vibration absorption device comprises a sealing base and a vibration absorption support, wherein the vibration absorption support is arranged between the upper pile foundation body and the lower pile foundation body. The lower portion of the sealing base is connected with the lower pilefoundation body. A sealing structure is arranged between the upper portion of the sealing base and the upper pile foundation body. The sealing base comprises a first base body and a second base body,wherein the first base body is welded to the second base body. The sealing structure comprises a sealing component, a first matched component and a second matched component, wherein the sealing component is arranged on the upper pile foundation body, the first matched component is arranged on the first base body, and the second matched component is arranged on the second base body. According to the building pile foundation, by means of the sealing base, the whole vibration absorption device is wrapped by the building pile foundation, so that it is guaranteed that two components of the vibration absorption device can still act relative to each other flexibly; thus, the vibration absorption effect is better, and the earthquake proof level is higher; and the building pile foundation adapts to earthquake resistance of a building in an area high in vibration sense to a greater extent.

Description

technical field [0001] The invention belongs to the technical field of building anti-seismic technology, and in particular relates to a building pile foundation. Background technique [0002] In recent years, earthquakes have occurred frequently in our country, and the country has increased the seismic requirements for buildings. The new buildings constructed today basically have good seismic effects, improving people's living safety. However, for the buildings constructed before that, their anti-seismic effect is poor, and the living safety is extremely low. [0003] In order to solve the above problems, Chinese patent CN105649100B discloses "A Seismic Isolation Reinforcement Method for Existing Impact Buildings", in which a new pile foundation is poured under the pile foundation of the original building, and then shock absorption is set between the two pile foundations. device, and then pouring to achieve shock absorption between the two. However, under this structure, t...
