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.
[0004] Moreover, the floating distance between the upper and lower pile bases is very small, which greatly affects the shock absorption effect, and it is difficult to meet the national seismic requirements, and its seismic performance and safety performance need to be improved

Embodiment 1

[0029] Such as Figure 1-6 As shown, a construction pile foundation includes an upper pile base 1, a lower pile base 2 and a shock absorbing device matched with the upper and lower pile bases; specifically, the shock absorbing device includes a sealing seat 3 And a shock-absorbing support 4 arranged between the upper and lower pile foundations; the lower part of the sealing seat 3 is connected to the lower pile foundation 2, and the upper part of the sealing seat 3 is connected to the upper pile foundation 1 A sealing structure is provided therebetween; the sealing seat 3 includes a first seat body 31 and a second seat body 32 that are welded to each other. Specifically, the first seat body 31 includes an upper connecting plate 311, a lower connecting plate 312, and a device On the middle plate 313 between the upper and lower connecting plates, the upper part of the middle plate 313 is welded and fixedly connected to the upper connecting plate 311, and the lower part of the midd...

Embodiment 2

[0035] The difference between this embodiment and embodiment 1 lies in: Figure 7-10 As shown, the sealing component 5 includes an annular sealing groove 54 provided on the upper pile base, an upper pressing portion 55 and a lower pressing portion 56 through which the upper pressing portion 55 and the lower pressing portion 56 pass The concrete is poured and formed on the upper pile base. The upper pressing portion 55 and the lower pressing portion 56 are both arranged in an annular structure, and the annular sealing groove 54 is provided between the upper and lower pressing portions; , The upper connecting plate can penetrate into the annular sealing groove 54; further, the lower surface of the upper pressing portion 55 is provided with a first leak-proof layer 551, and the upper surface of the lower pressing portion 56 is provided with The second leakproof layer 561, the annular sealing groove 54 is provided with a third leakproof layer 541; the first leakproof layer 551, the...

Abstract

The invention discloses an earthquake-resistant building pile foundation. The earthquake-resistant building pile foundation comprises an upper pile foundation body, a lower pile foundation body and adamping device matched with the upper pile foundation body and the lower pile foundation body. The damping device comprises a sealing seat and a damping support arranged between the upper pile foundation body and the lower pile foundation body. The lower portion of the sealing seat is connected with the lower pile foundation body. A sealing structure is arranged between the upper portion of the sealing seat and the upper pile foundation body. The sealing seat comprises a first seat body and a second seat body welded with the first seat body. The sealing structure comprises a sealing part arranged on the upper pile foundation body, a first matching part arranged on the first seat body, and a second matching part arranged on the second seat body. By arranging the sealing seat, the whole damping device is wrapped in the pile foundation, the effect that two parts of the damping device still can achieve interact flexibly is ensured, thus, the damping effect is better, the earthquake-resistant degree is higher, and the earthquake-resistant building pile foundation is more suitable for building earthquake resistance of strong felt regions.

Description

Technical field [0001] The invention belongs to the technical field of building earthquake resistance, and in particular relates to a seismic building pile foundation. Background technique [0002] In recent years, my country has experienced a high incidence of earthquakes, and the country has improved the seismic requirements of buildings. The new buildings constructed today have basically good seismic effects and improve people's living safety. However, for the buildings constructed before this, the seismic effect is poor and the living safety is extremely low. [0003] In order to solve the above problems, Chinese patent CN105649100B discloses "A method for seismic isolation and reinforcement of existing impacted buildings", which is achieved by pouring a new pile foundation under the pile foundation of the original building, and then setting a shock absorber between the two pile foundations. The device, after pouring, realizes the shock absorption between the two. However, un...
