Self-supply glass bead-graphite base sliding vibration isolation system and its method

Abstract

The invention discloses a self-supply glass bead-graphite base sliding isolation system and a method, characterized in that a limit hole rebar is located in the center of each of limited holes, one end is fixed in a base underbeam in a anchoring manner, the other end passes through the corresponding limit hole and perforates a base upperbeam, and sand is filled in the part, located on base underbeam, of the limit holes; a trumpet-shaped groove for placing a lead pipe is revered between the two limit holes, when concrete of the base underbeam reaches a certain intensity, the lead pipe is installed in the trumpet-shaped groove, and a mixture of glass beads and graphite is filled in the lead pipe; when the concrete of the base underbeam reaches a certain intensity, glass bead-graphite rolling isolation layer is paved on the surface of the base underbeam; on the base upperbeam, a supplying hole is reserved between the two lead pipe-glass bead-graphite energy dissipation shock absorbers; when the base upperbeam reaches a certain intensity, walls are constructed on the upper part of the base upperbeam, so that the self-supply glass bead-graphite base sliding isolation system is formed.

Description

technical field [0001] The invention relates to a self-replenishment type glass bead-graphite foundation sliding shock-isolation system and its method and production method, belonging to the field of building shock-isolation and disaster reduction. Background technique [0002] my country has a vast territory and a large population. Most buildings are located in earthquake zones. Most of the multi-storey buildings are masonry structures or frame-filled wall structures, which have poor earthquake resistance. On May 12, 2008, the magnitude 8.0 Wenchuan earthquake caused 16 provinces (municipalities, autonomous regions), more than 417 counties (cities, districts), 4,624 towns, and 46,574 villages in Sichuan, Gansu, Shaanxi, and Chongqing to be affected to varying degrees. The affected area is about 440,000 km 2 In this earthquake, 69,227 people were killed, 374,643 people were injured, 17,923 people were missing, and the direct economic loss reached 845.1 billion yuan. The dir...
