Problems solved by technology
Under the action of the earthquake, since there is no bond between the prefabricated floor slab and the ring beam, as long as one end of the prefabricated floor slab is displaced beyond the shelving length, it will cause the overall collapse of the house and cause a large number of casualties

[0019] The present invention proposes that in the design of the existing masonry structure, in addition to the structural design according to the original design standard, a more solid rigid body space is set up on the basis of the original safety design. The space is composed of 8 steel beams 5 and 4 steel columns 4 on the upper and lower sides. The upper and lower surfaces of the space are pulled by 8 pairs of steel diagonal braces, and the other four surfaces are all equipped with friction dampers 1 and 4 steel columns. The steel beam 5 and the shaped steel column 4 are connected to form a solid rigid body—the safety refuge warehouse. When a strong earthquake strikes, the existing masonry structure and the safety refuge warehouse jointly resist the invasion of seismic waves. Even if the masonry structure has large cracks, or even partially breaks and falls off, the safety refuge warehouse may locally occur due to the good ductility of the steel structure. Deformation, but t...

Abstract
The invention relates to a safety bin modified from an old abandoned house masonry structure and belongs to the field of earthquake proofing technologies. A steel structure device is installed in a house with a masonry structure, the steel structure comprises four section steel columns and 8 section steel beams, the four section steel columns are installed at four corners of the house with the masonry structure, and the eight section steel beams are respectively connected with the four section steel columns, so that a hexahedral space is composed; and an upper surface and a lower surface of the space is pulled opposite by using inclined steel struts, the other four surfaces are connected through a friction damper, section steel beams and section steel columns, and then steel plates are welded on an upper surface and a lower surface of the safety refuge bin which is connected with the friction damper. When an earthquake happens, the construction masonry structure and the safety refuge bin resist attack of earthquake waves, a large moving space in the safety refuge bin is guaranteed, persons hiding in the safety refuge bin can not be crushed by masonry blocks, the rescuing time of the persons are delayed, and remarkable economic and social benefits are achieved.
Description
technical field [0001] The invention relates to a masonry structure reconstruction safety shelter for old houses, which belongs to the field of anti-seismic technology. Background technique [0002] At present, most of the old houses in our country are masonry brick-concrete structures. Due to the low construction cost of masonry structures, a large number of masonry structures were built in my country before the mid-1990s. Masonry structures are widely used in residential buildings, office buildings, schools, hospitals and shopping malls in my country. Due to the brittle nature of masonry structure materials, their shear, tensile and flexural strengths are relatively low, resulting in the earthquake resistance of masonry buildings. Poor ability. In previous strong earthquakes at home and abroad, the masonry structure was severely damaged, and the prefabricated floor brick-concrete structure suffered the most serious damage, which can be said to be a devastating overall coll...
