Steel-wood combined vibration isolation pad foundation and mounting method thereof

Abstract

The invention relates to the field of building construction, and discloses a steel-wood combined vibration isolation pad foundation and a mounting method thereof. The steel-wood combined vibration isolation pad foundation comprises a reinforced concrete foundation, a combined vibration isolation pad, a steel sleeve and a wood column, wherein the reinforced concrete foundation comprises a lower layer foundation and an upper layer foundation, a plurality of parallel first transverse reinforcing steel bars, parallel vertical reinforcing steel bars and parallel steel bar embedded parts are arranged in the lower layer foundation, the combined vibration isolation pad comprises an upper cover plate, a plurality of inner clamping plates and a lower cover plate which are arranged from top to bottom, the outer side of the combined vibration isolation pad is sleeved with the steel sleeve, the wood column is inserted into the steel sleeve and is connected with the steel sleeve through bolts, and the vertical steel bars penetrate through the wood column and extend out of the top of the wood column. According to the steel-wood combined vibration isolation pad foundation, the seismic energy consumption of an existing foundation structure can be effectively increased, damage to the existing structure during earthquake generation is reduced, seismic energy is consumed through the horizontal displacement generated by rubber balls, and the security of the structure is improved; and the vibration isolation pad has good self-resetting performance and deformation recovery capability through theSMA rubber bolts after the earthquake.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a steel-wood composite foundation and an installation method for the foundation. Background technique [0002] At present, based on the reality of frequent earthquakes, the seismic fortification of buildings has received more and more attention. In architectural design, the design of anti-seismic components is related to the safety of the structure in the later stage. The seismic isolation structure has been recognized by the engineering community because of its good shock absorption effect. The working principle of the seismic isolation structure is to set a slip layer or isolation layer between the building and the foundation to prevent the seismic energy from being transmitted upwards, thereby reducing the seismic response of the structure. [0003] The existing seismic isolation systems that are relatively mature and widely used in practical engineering mainly include t...

Problems solved by technology

However, there are certain problems in the above-mentioned systems. The main disadvantage of the laminated rubber bearing isolation system is that it generally has no damping effect on vertical vibration, and it is easy to resonate with horizontal vibration with a long natural vibration period, which affects the isolation. The safety of the bearing itself; and the traditional laminated rubber seismic isolation bearing has problems such as heavy weight, high cost, and complicated installation process. Although its production technology is basically mature, there is still room for improvement and improvement in material performance. In addition , the early friction-slip isolation mostly set a strip-shaped slip layer along the strip foundation, which is undoubtedly economical, but there are many problems such as difficult construction leveling and reset
