Embodiment Construction

[0027] A kind of existing building enclosing type adding layer structure of the present invention, the specific embodiment is as follows Figure 1-4 As shown, the existing building is surrounded by a surrounding structure, and the surrounding structure is all made of steel structure. The surrounding structure surrounds the outer wall 3 of the existing building and is connected end to end on the plane. Newly added load-bearing steel columns 1, newly added longitudinal steel beams 2, newly added horizontal steel beams 10, outer steel columns 14, bearing beams 4, 4 inner angle steel columns 12 and 4 outer angle steel columns 13; Between the outer steel column 14 and the newly added heavy-duty steel column 1 and between the outer steel column 14 and the inner angle steel column 12, a newly added horizontal steel beam 10 is installed, and between the outer steel column 14 and between the outer steel column 14 and the The outer angle steel columns 13 are connected with newly-enclose...

Abstract

The invention relates to an existing building surrounding type story-adding structure and a construction method thereof, and belongs to the field of structure seismic strengthening. According to the invention, outer covering type steel structures are added on the periphery of an existing building, and the steel structures surround the existing building and are connected end to end on the plane, so that the horizontal seismic load of the whole structures can be effectively increased. According to the invention, when newly added load-bearing type steel columns of the surrounding type structures exceed the top part of the existing building, load-bearing cross beams are arranged and connected with the newly added load-bearing type steel columns. The whole load at the upper parts of the newly added load-bearing cross beams is transmitted to the newly added load-bearing type steel columns and then the foundation. The surrounding type story-adding technology enables the new structures and the old structures to be closely connected in a hinged or rigid manner, so that the structure stability is increased, the stress system of the whole structure is reasonable, and the safety and the reliability of the whole structure are ensured. Through existing building surrounding type story-adding construction, the present problem about housing difficulty of people is solved and meanwhile a great deal of land resource of the nation is saved.

Description

technical field [0001] The invention relates to an existing building envelope-type layer-adding structure and a construction method thereof, belonging to the technical field of seismic reinforcement. Background technique [0002] Our country is a country with many people and little land, which restricts the development of cities. At present, due to the constraints of the country's economic situation, it is still impossible to demolish a large number of old houses and rebuild new houses to solve the difficult situation of people's housing. With the growth of population and the development of economic construction in our country, this phenomenon is becoming more and more obvious. Therefore adopting to increase the number of floors on the original building (that is, adding floors to existing buildings) to meet people's housing needs is a more practical way to alleviate the current housing shortage, and it also saves the country's land resources. It can be said to kill two bird...
