Description
Technical field
The present invention relates to a kind of old community not register one's residence balcony rapid reinforcement structure and construction method thereof, belong to technical field of anti-seismic reinforcement.
Background technology
Implementing old community strengthening reconstruction is a project supported by commen people paid close attention to the well-being of the people and benefit the masses, its objective is that the quality of life making resident is effectively promoted, and makes the residential security of resident effectively be ensured. Old community before the eighties is built in for some, because of its planning construction age early, construction criteria is relatively low, the problems such as the equipment that also exists to some extent is long neglected and in disrepair, building body decoration peeling, energy-saving heat preserving weak effect, it is necessary to it is carried out strengthening reconstruction. And the balcony ingredient that to be house important, also it is the important place of people's daily life, its safety is particularly important. Due to the long-term load-bearing of balcony, the year problem such as aging for a long time, balcony floor occurs in that inclination in various degree and crack, has a strong impact on the safety of inhabitation, it is necessary to it is reinforced. But, when building is reinforced, the daily life of resident can be affected, indivedual residents construction team that is unwilling registers one's residence construction. In order to avoid construction of registering one's residence too much, dry operation rapid reinforcement balcony is first-selected.
Summary of the invention
Based on the problems referred to above, the present invention is in conjunction with old community comprehensive reformation engineering, it is proposed that do not register one's residence balcony rapid reinforcement structure and construction method thereof in a kind of old community. Efficiently solve and old Urban re-development process affects resident family's daily life and does not register one's residence balcony is carried out the technical problem of rapid reinforcement.
Technical scheme is as follows:
