Description
Technical field
The present invention relates to anti-seismic strengthening device of prefabricated hollow floorslab brick mixed structure building floor.
Background technology
Made a general survey of macroseism since global 20th century, 8.8 grades of U.S.'s Alaska violent earthquake (on March 28th, 1964) Richter scales, 125 people's death; On Japanese January 17 nineteen ninety-five, slope is distinguished celestially 7.3 grades of macroseisms is taken place, and is murdered for 6434 ... and the loss of China is the most heavy in all previous earthquake, and only Tangshan earthquake and this Wenchuan earthquake just have 300,000 people of surpassing to die in an accident.
Beginnings in 1996 after slope shakes celestially, " building standard method " revised 3 times by Japan, and all kinds of building aseismicity benchmark are all brought up to highest level, especially requires commercial building shock resistance will reach more than 8 grades, and useful life can be above 100 years.2000, the Bingku county at place, Kobe used triennium that the dwelling house in the whole county is carried out the free anti-diagnosis of shaking, and the house not enough to resistance to vibration reinforced by county's financial burden.The U.S. is also corresponding has improved the Anti-quake Architectural Structure Design grade, and on a large scale built house is carried out seismic hardening, and the enforcement of these a series of preventive action just makes them to reduce to the disaster that earthquake causes minimum just.Relevant departments such as our government, relevant industrial department, Architectural Design Study mechanism and construction field must accomplish something for this reason, can not entertain any lucky psychology again and allow tragedy showing again and again.
Brick mix structure has obtained extensive use in buildings such as China's dwelling house, office building, school, hospital, shop.Because the fragility character of masonry structure material, its shearing resistance, tension and flexural strength are low, so the shock resistance of masonry house is relatively poor, in all previous at home and abroad violent earthquake, it is quite serious that masonry structure destroys.And wherein serious with the damage of prefabricated hollow floorslab brick mixed structure, be that destructive integral body collapses substantially, from the Wenchuan and the earthquake result of big twice of Tangshan also fully verified this point.The reason of prefabricated hollow floorslab brick mixed structure building shock resistance difference is: prefabricated hollow floor be cassette ceiling block-by-block handling that precast yard is produced to brick wall, its two ends be shelved on the wide collar tie beam of b=240mm form flooring, bear vertical load.The shelving length on every limit is a=80mm by regulation and stipulation.Cassette ceiling under geological process because and between the collar tie beam without any being adhesively fixed, as long as the one end take place to surpass shelving length displacement, will cause that the integral body in house collapses.Because cost is cheap relatively, China had built buildings such as the dwelling house, schoolhouse of prefabricated hollow floor structure in the past in a large number in the mid-90 in last century, recognized the anti-seismic performance deficiency of the type building afterwards, satisfied in the mid-90 and forbidden adopting, but those existing houses of having built are not taked essence, effective reinforcement measure so far yet, and industry does not have the effective technology at the seismic hardening of prefabricated hollow floor flooring at present yet.
