Restorable steel-wood independent foundation and its installation method

Abstract

The invention relates to the field of building construction, in particular to a recoverable steel-wood independent foundation, which includes a concrete independent foundation, an energy-dissipating device, a connection device and a wooden column, the energy-consuming device is fixed on the concrete independent foundation, and the wooden column The connection device is fixedly connected with the energy-dissipating device; the energy-dissipating device includes a square steel pipe and a steel plate I, the steel plate I is horizontally fixed in the square steel pipe, a number of prestressed steel bars are vertically arranged on the steel plate I, and springs are covered on the prestressed steel bar; the connecting device It includes steel plate II, steel plate III, clamping plate and seismic isolation support, and vertical reinforcement is arranged in the wooden column. The invention adopts a steel-wood composite structure, which does not weaken the strength of the wooden column along the grain direction, ensures the anti-seismic performance of the structure, and improves the utilization rate of different material properties; uses prestressed steel bars to make the structure recoverable, and at the same time improves the column structure. The reliability of the feet prevents the structure from being damaged when it encounters an earthquake, or it is easy to repair after the earthquake damage.

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.
