Abstract
The invention relates to an additionally assembled type balcony structure for an old community and a construction method of the additionally assembled type balcony structure, belonging to the technical field of reinforcement and reconstruction. The additionally assembled type balcony structure comprises an additionally assembled type balcony structure body which is arranged at a ring beam under an original structure outer wall and connected with the ring beam in an anchored manner; the additionally assembled type balcony structure body consists of a newly added column foundation, newly added steel columns, newly added prefabricated concrete balcony plates, newly added steel handrails and newly added glass baffles. The connecting measures and the construction method of each layer of newly added fabricated concrete balcony plates and the ring beam under the outer wall on one side of the wall body are the same. The additionally assembled type balcony structure and the construction method disclosed by the invention can realize the purpose of increasing the prefabricated concrete balcony plates by reliably connecting anchored hoop reinforcements and main ribs of the ring beam and additionally arranging the steel columns to bear a part of weight of the balcony on the basis of short construction time, simple technology and low cost in the old community reconstruction, and can be widely applied to building reconstruction for improving the life convenience by additionally arranging the balcony.
Description
Technical field
The present invention relates to a kind of old House Reconstruction structure and construction method thereof, the additional assembling in a kind of old community
Formula balcony structure and construction method thereof, belong to strengthening reconstruction technical field.
Background technology
Along with stepping up of urban life level, the continuous improvement of economic condition, people are to the requirement of quality of life also
More and more higher.The a lot of old residential quarters of China are built in the 80s and 90s, at that time owing to being limited by factors such as economic conditions,
Building function is simple, and design model is single, and quality of life is poor, needs downstairs just to enjoy sunlight to the full, and airing clothes is the most not
Convenient.In the transformation of old residential quarters, these are built into for the object of emphasis transformation.The daily life of resident for convenience
Live, allow resident live more comfortable in the future, substantial amounts of fund need not be put into again, additional assembled on the exterior wall of old residential quarters
Balcony structure then becomes a kind of cry of the people.Meanwhile, balcony not only can increase the design of building, main
It is to provide to the resident living in old residential quarters to have a rest and the place of amusement, therefore, increases balcony knot in old community
It is configured to a problem urgently to be resolved hurrily in current seismic hardening.
To this end, we have proposed additional Fabricated balcony at exterior wall collar tie beam to solve this problem well, make old
The building function of community is increased.Owing to balcony uses in advance at the assembled of plant produced, and it is connected with original structure
Convenient and reliable, the method short construction period, is the most practical a kind of reforming mode, in the case of economic condition is permitted, to both
Old residential quarters are had to use the transformation of additional Fabricated balcony to have the biggest development prospect and realistic meaning.
Summary of the invention
Based on the problems referred to above, the present invention combines old residential quarters comprehensive reformation engineering, it is proposed that outside a kind of old community
Add assembled balcony structure and construction method thereof.Primarily to solve existing old residential quarters due to economy, technology bar
The restriction of part is not provided with balcony, and building uses function can not meet the present high-quality life requirement of people, needs to set up sun
Platform makes the technical problem that the life of resident is more comfortable.
Technical scheme is as follows:
A kind of old community additional Fabricated balcony structure, including original structure, also includes and original structure exterior wall lower ring beam anchor
