Multi-storey residential building integrated renovation construction method

Abstract

A multi-storey residence integrated renovation construction method, comprising the following steps: (1) arranging concrete shear wall elevator shafts at corresponding positions in the outdoor stairwell or patio of the multi-storey house; (3) Set up buttress columns at the junction of vertical and horizontal walls of multi-storey residential buildings close to the original wall; (4) Concrete roof girders are poured on the top of the roof above the buttress columns and pre-embedded for anchorage The top of the roof adopts a sloping roof steel structure to add layers. The invention avoids the waste of resources and energy caused by separate operations, reduces the adverse effects of house entry and construction on residents and the surrounding environment, effectively improves structural safety and seismic performance, and can be widely used in 6-8 degree earthquake-resistant fortified areas. Compared with the unmodified original structure, the overall seismic capacity of the structure has increased by more than one and a half degrees, the stiffness and ductility have been greatly improved, and the brittle failure characteristics of the masonry structure have also been significantly improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, and in particular relates to an integrated renovation and construction method for a multi-storey house, which can realize the purpose of adding elevators, adding floors, leveling and changing slopes, and seismic reinforcement for the existing multi-storey houses at the same time. 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 These multi-storey b...

AI Technical Summary

Problems solved by technology

[0003] The present invention is aimed at the defect that in the process of adding elevators, adding floors, changing slopes and anti-seismic reinforcement in the existing multi-storey residential buildings, the separate construction of each reconstruction project is likely to cause waste of resources and affect the daily life of residents. The construction method of residential integrated renovation, the integrated design of adding elevators, adding floors, changing slopes and seismic reinforcement of existing multi-storey houses, that is, while adding elevators, single-sided concrete slab walls are used to repair the outer walls of existing multi-storey houses. The building is reinforced against earthquakes, and buttress columns are added outside the walls of the existing multi-storey residential structure, concrete girders are added to the roof, and the upper part is added with a sloping roof steel structure to improve the seismic performance of the existing multi-storey residential building
