Recoverable steel-wood independent foundation and installation method

Abstract

The invention relates to the field of building structures, in particular to a recoverable steel-wood independent foundation. The recoverable steel-wood independent foundation comprises a concrete independent foundation, an energy dissipation device, a connecting device and a wood column, wherein the energy dissipation device is fixed on the concrete independent foundation, and the wood column is fixedly connected with the energy dissipation device through the connecting device; the energy dissipation device comprises a square steel pipe and a steel plate I, the steel plate I is horizontally fixed in the square steel pipe, and a plurality of prestressed steel bars are vertically arranged on the steel plate I, and are sleeved with springs; and the connecting device comprises a steel plate II, a steel plate III, a clamping plate and a shock insulation support, and vertical steel bars are arranged in the wood column. Due to the adoption of a steel-wood composite structure, the strength ofthe wood column in the grain direction is not weakened, the anti-seismic performance of the structure is guaranteed, and the performance utilization rate of different materials is improved; by means of the prestressed steel bars, the structure has recoverable characteristics, reliability of column feet is improved, the structure is prevented from being damaged when the structure is subjected to anearthquake, or the structure is easy to repair after being damaged by the earthquake.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a steel-wood independent foundation. Background technique [0002] With the development of the construction industry, the anti-seismic design of structures should not only be satisfied with the protection of life safety when an earthquake occurs, but should place equal importance on the recovery of life and production in the disaster-stricken area after the earthquake. Compared with the traditional seismic design, which focuses on protecting life when an earthquake occurs, and ignores the consequences that the structure cannot bear the original function for a long period of time after the earthquake, the recoverable structure can solve the above problems very well. It shows its unique advantages in the construction industry. [0003] As one of the most important building materials, steel has the advantages of high strength, light weight, and good ductility. However, steel is l...

AI Technical Summary

Problems solved by technology

However, the existing steel-wood composite structure is prone to damage and is not easy to repair when an earthquake occurs, and its recoverability is poor. After the earthquake, it cannot continue to be used, resulting in large economic losses.
