Additional elevator arranging and seismic reinforcement integral construction method for multi-storey houses

Abstract

The invention discloses an additional elevator arranging and seismic reinforcement integral construction method for multi-storey houses. The additional elevator arranging and seismic reinforcement integral construction method is characterized by comprising steps of (1), additionally arranging elevator shafts with reinforced concrete shear walls at corresponding positions of outdoor stair halls or open yards of the existing multi-storey houses; (2), reinforcing the outer sides of peripheral walls of the multi-storey houses by the aid of wire mesh cement mortar surface layers or single-side concrete plate walls. The additional elevator arranging and seismic reinforcement integral construction method has the advantages that additional elevator arranging and seismic reinforcement requirements of the existing multi-storey houses can be simultaneously met, resource and energy wastage due to the fact that additional elevator arranging and seismic reinforcement requirements are individually met can be prevented, adverse impact of indoor construction and the like on residents and surrounding environments can be reduced, the structural safety and seismic performance can be effectively enhanced, and the additional elevator arranging and seismic reinforcement integral construction method can be widely used for seismic fortification zones for seism of 6-8 degrees; after additional elevator arranging and seismic reinforcement modification is carried out by the aid of the technical method, the integral seismic capacity of structures can be improved by one degree at least as compared with original unmodified structures, the rigidity and the ductility of the structures can be greatly improved, and brittle failure characteristics of the masonry structures are improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an integrated construction method of adding elevators and anti-seismic reinforcement for multi-storey houses, which can achieve the purpose of improving the seismic strength of houses while adding elevators to existing multi-storey houses. Background technique [0002] At present, there are many multi-storey buildings in the 1980s and 1990s or even earlier in our country. Due to historical and construction technology reasons, many existing multi-storey residences do not have elevators. figure 1 As shown, it is not very convenient for residents living in high-rise buildings. At the same time, the earthquake resistance of these early buildings does not meet the requirements of modern buildings. With the economic development, the improvement of living standards and the aging of urban population, it is necessary to improve of these multi-storey buildings. At present...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the defect that existing early multi-storey buildings are constructed separately in the process of adding elevators and anti-seismic reinforcement, which is likely to cause environmental pollution, affect people's normal life, and have high cost, and provides an integration of adding elevators and anti-seismic reinforcement in multi-storey residential buildings The construction method, adding elevators and seismic reinforcement work to multi-storey buildings at the same time, shortens the construction period, reduces construction costs, reduces the impact of building construction and renovation on residents, and protects the environment
