Existing building exterior wall reconstruction structure and construction method

Abstract

The invention discloses an existing building exterior wall reconstruction structure and a construction method. The existing building exterior wall reconstruction structure comprises a newly-built wallbody, vertical reinforcing steel bars, horizontal reinforcing steel bars and tie bars, wherein the newly-built wall body is tightly attached to the outer side face of an existing building wall body,and is built with porous bricks; pores of upper-layer porous bricks and lower-layer porous bricks of the newly-built wall body are vertically formed correspondingly; one group of horizontal reinforcing steel bars is arranged at intervals along the outer side face of the existing building wall body; the vertical reinforcing steel bars are inserted into the pores of the porous bricks in the full length; one group of horizontal reinforcing steel bars is arranged at intervals along a vertical direction; the horizontal reinforcing steel bars are arranged in mortar joints of two adjacent layers of porous bricks; the two ends of the horizontal reinforcing steel bars are fixedly connected with the vertical reinforcing steel bars on a corresponding side; the tie bars are horizontally arranged between the existing building wall body and the newly-built wall body. The existing building exterior wall reconstruction structure and the construction method provided by the invention have the advantagesthat the technical problems of difficulty in reconstructing and upgrading the existing wall body and recovering the original appearance, incapability of making the building reach designed service life and resource waste are solved.

Description

Technical field [0001] The invention belongs to the field of construction engineering, and particularly relates to an existing building exterior wall reconstruction structure and a construction method. Background technique [0002] With the continuous development of urban construction in my country, large-scale construction, development, and urban cultural inheritance and protection have always contradicted each other. Among them, the representative and larger ones are the ones from the 1970s to the 1990s. Old buildings, such as factory workshops, clubs, workshops, and some government commissions and bureaus, and other office buildings with masonry structure. These buildings are outdated in terms of function and comfort, and their appearance is also dilapidated, which cannot satisfy people’s desire for modern buildings. Claim. However, in view of the requirements for the preservation and inheritance of urban cultural features in the overall planning of the central city, some valua...
