A planning and design method for earthquake-resistant complexes of old buildings

Abstract

A planning and designing method for an old building anti-seismic building group includes the following steps that firstly, an opening is formed in an old building (1); secondly, the opening is reinforced; thirdly, an elevator shaft (11) and a walking deck are installed; fourthly, H-type steel reinforcement parts (19 and 20) are arranged on the outer side of a construction pillar (15) and on the outer side of a ring beam (16); fifthly, a friction damper (24) is arranged on the horizontal H-type steel reinforcement part (19) to connect an anti-buckling support (27) with an upper fixing part (25) and a lower fixing part (26) through connecting plates (23); and sixthly, walking decks II (13) of different old buildings are connected through walking decks III (14). The planning and designing method can improve the anti-seismic performance of buildings and the living quality of residents, is adaptive to the outer environment, and is low in cost and good in safety.

Description

technical field [0001] The invention relates to the field of planning and design of buildings, in particular to a planning and design method of an old building anti-seismic building group. Background technique [0002] With the development and progress of society, people have higher and higher requirements for living conditions. A large part of the existing residential houses are brick-concrete six-storey buildings before 2000. Especially the occurrence of the Wenchuan Earthquake caused people to worry about the seismic performance of the old six-story brick-concrete buildings, and there were no elevators in such buildings. toddler. Occurred in the prior art the technology that elevator is installed on the old building of six floors, this technology generally is to arrange lift elevator on the facade of house, and the setting of this lift elevator destroys original building structure on the one hand, makes The anti-seismic performance of the building is degraded.

AI Technical Summary

Problems solved by technology

In particular, the Wenchuan Earthquake caused people to worry about the seismic performance of the six-storey brick-concrete buildings, and there were no elevators in such buildings. toddler

In the prior art, the technology of installing elevators on six-storey old buildings has appeared. This technology is generally to set elevators on the facades of houses. The setting of elevators destroys the original building structure on the one hand. The anti-seismic performance of the building is reduced. On the other hand, the elevator shaft is not integrated with the surrounding environment, and the installation is very abrupt, which affects the environment of the community and the living quality of residents. In addition, the cost of installing and operating elevators is expensive for this type of transformation. Therefore, there is an urgent need for a planning and design method for a six-story brick-concrete old building group, which can not only improve the seismic performance of the house, but also improve the quality of life of the residents, adapt to the external environment, and have low cost and good safety
