Cylindrical shell body building unit and low-cost module-type anti-seismic building formed by cylindrical shell body building unit

Abstract

The invention relates to a cylindrical shell body building unit and a low-cost module-type anti-seismic building formed by the cylindrical shell body building unit. A cylindrical shell body building unit main body is a cage-shaped steel structural body with a large enough length-diameter ratio which is formed by an axial steel beam and a circular annular-shaped steel beam. The interior of cylindrical shell body building unit main body is provided with a building formed by one layer or multi-layer rooms, a low-cost module-type anti-seismic building formed by a low-cost base, a gravel friction damping layer arranged on the upper portion of the low-cost base, cylindrical shell body building unit heaps which are heaped on the upper portion of the gravel friction damping layer in a stacked mode, a low-cost module-type anti-seismic building which is formed by shape limiting frames and arranged on the outside of the cylindrical shell body building unit heaps and a low-cost module-type anti-seismic building which is combined by the cylindrical shell body building unit heaps and a central cuboid building. According to the cylindrical shell body building unit and the low-cost module-type anti-seismic building formed by the cylindrical shell body building unit, when the anti-seismic capacity is designed below 9 degrees, elastic shaking only happens, and damage does not happen; when the anti-seismic capacity is above 9 degrees, tremendous destructive power of an earthquake is weakened by relying on an active preset slowly-collapsing process of pipe stacks, and the ultra strong anti-seismic capacity is achieved.

Description

technical field [0001] The invention relates to an anti-seismic building, in particular to a cylindrical shell building unit and a low-cost modular anti-seismic building composed of the same. Background technique [0002] Japan is an earthquake-prone country and has a lot of advanced experience in earthquake resistance. For example, light wood structures are effective in resisting earthquakes, but if they are added with tsunamis, they will become vulnerable; modern developments have developed into high-strength elastic structures, or in the main building. Set rolling layer, damping layer, etc. between the object and the foundation. The famous Silkworm Cocoon Building in Tokyo, Japan has combined a lot of advanced anti-seismic experience and has withstood the test of many earthquakes. His concept is active anti-seismic, which is mainly manifested in: one is the ballast block, and the other is the elastic cable that binds the building; The third is a jet thrusting device powe...

Problems solved by technology

This structure utilizes the good mechanical structure of the tubular unit house, but the tubular unit house is arranged in a rectangular frame with a general mechanical structure, and the seismic capacity of the rectangular frame becomes a limiting link, which does not greatly improve Breaking away from the range of seismic capacity of traditional rectangular buildings, the construction cost is increased needlessly, and it is not suitable for repair after damage, so there are certain limitations in implementation

[0006] One embodiment of the Chinese patent CN202767239U "a high earthquake-resistant building" adopts the architectural structure of the built-in unit house in the honeycomb hexagonal frame, and has improved the CN201502204U "cylindrical shell building unit earthquake-resistant building", but it still does not break away from the frame The idea of ​​using it with the unit house, the cost of the honeycomb hexagonal frame is still high

[0007] Chinese patent CN 101619625A "Shock-resistant spherical latitude and longitude steel building design scheme" gives a building structure with a large spherical shape as a whole, which has the ability to resist super earthquakes. However, the larger the diameter of the ball, the larger the mechanical properties of the spherical surface. will gradually approach the plane, therefore, the construction scale of this structure is limited, and the cost will rise sharply if the diameter is too large

[0008] Chinese patent CN 101397819A "hexagonal honeycomb earthquake-resistant building frame structure" also adopts the building structure of honeycomb hexagonal frame, which improves the structural strength, but the shape is still a vertical frame column, and it still does not have the ability to resist super earthquakes at low cost
