Short-leg shear wall frame structure of existing building storey adding and construction method of short-leg shear wall frame structure

Abstract

The invention discloses a short-leg shear wall frame structure of an existing building added layer and a construction method of the short-leg shear wall frame structure, belongs to the field of building design, and solves the problems of wall surface damage, poor anti-seismic property, lighting influence, high construction difficulty and long construction period of an existing outer sleeve type frame structure. A plurality of shear walls are symmetrically arranged on the two sides of the existing building, connecting beams are connected between the corresponding shear walls, the connecting beams are located above the top of the existing building, and the multiple connecting beams are connected through girders to form a beam body frame. The construction method comprises the steps that foundations are symmetrically constructed on the two sides of an existing building, and shear walls are constructed on the foundations; connecting beams are constructed between the corresponding shear walls, and the connecting beams are suspended above the existing building; a girder is constructed perpendicular to the connecting beams, and the multiple connecting beams are connected into a whole through the girder. During construction, the wall surface of the existing building cannot be damaged, and the existing building can be covered with multiple layers; the method is beneficial to seismic resistance, has small influence on lighting of the existing building, and is simple in construction method and short in construction period.

Description

technical field [0001] The invention belongs to the field of architectural design, and in particular relates to a short-limb shear wall frame structure and a construction method for adding floors to an existing building. Background technique [0002] With the continuous development of society, the original area of ​​many buildings cannot meet the needs of use, and many units use the method of adding floors to the original buildings to solve production and use problems. Because the building addition is different from the new building, the addition of the building will be restricted by many aspects, and it is necessary to check the bearing capacity of the original building, especially for the brick-concrete structure, the addition of the building will be more difficult. [0003] The existing jacket-type extra-story structure connects the frame on the periphery of the original building wall, and the upper end of the frame extends to the top of the original building, and the ext...
