Construction method for adding earthquake-proof layer to brick concrete building

Abstract

The invention relates to a construction method for adding an earthquake-proof layer to a brick concrete building. The construction method can effectively solve the problem that the house brick concrete building is collapsed due to an earthquake. The method comprises the steps that an indoor floor is broken and removed; indoor and outdoor trenches are excavated; an outdoor retaining wall is laid; pin key holes are punched in a foundation wall; a formwork is arranged in a lower plane of the pin key holes in a supporting manner; pin key steel and lower bracket beam steel are mounted; a lower bracket beam side formwork is arranged in a supporting manner; an earthquake-proof bearing is mounted; grouting is conducted; lower bracket beam concrete is poured; an inner upper bracket beam bottom formwork and an outer upper bracket beam bottom formwork of the foundation wall are arranged in a supporting manner; the pin key steel and upper bracket beam steel are mounted; an outdoor upper bracket beam side formwork and a cornice bottom formwork are arranged in a supporting manner; cornice steel is colligated; an indoor beam and slab structure formwork is arranged in a supporting manner; beam and slab steel is colligated; concrete is poured; the wall at the earthquake-proof bearing is broken and removed; the earthquake-proof bearing is mounted; an edge connection slab is leveled and pressed; the concrete is poured; the formworks are removed; and a site is cleared. The construction method is effectively used for rebuilding the existing brick concrete building, constructing a new building, and improving an earthquake-proof effect of the building.

Description

technical field [0001] The invention relates to buildings, in particular to a construction method for adding a shock-isolation layer to a brick-concrete building. Background technique [0002] Earthquakes are characterized by strong suddenness, short action time, and great destructiveness. At present, the scientific level of earthquake prediction is limited, and it is not yet possible to make accurate predictions of impending earthquakes. Major earthquakes at home and abroad, such as: Tangshan, Lancang, Wuding, Datong, Lijiang, Jiashi, Baotou, Taiwan, Wenchuan, San Francisco, Los Angeles, Kobe, Japan, etc., have caused damage to a large number of buildings and engineering facilities . At the same time, many anti-seismic new technologies have withstood the earthquake test, which proves that these technologies are effective and can be popularized and applied in our country. Therefore, effective earthquake-resistant fortification of buildings is still the key work for earthqu...

Problems solved by technology

Judging from the above regulations, the seismic requirements of most of the existing buildings in our country do not meet the new national standards. To demolish and rebuild these buildings will not only cost a lot of money and time, but will also bring great harm to urban traffic. pressure, it is unrealistic to do so

So how to make existing buildings meet the new national earthquake resistance standards, prevent buildings from collapsing during earthquakes, and reduce disaster losses caused by earthquakes, there is no effective solution so far. Therefore, it is necessary to develop new methods of earthquake resistance for buildings. technical problem
