Background
With the continuous development of society, the original area of many buildings can not meet the use requirement, and a plurality of units adopt a method of adding floors on the original buildings to solve the production and use problems. Because the building added layer is different with newly-built house, the building added layer can receive the restriction in a plurality of aspects, need carry out the check calculation to the bearing capacity of original building, especially to the brick and concrete structure, its added layer can be more difficult.
The existing outer sleeve type story-adding structure is characterized in that a frame is connected to the periphery of an original building wall, the upper end of the frame extends to the top of the original building, and story-adding construction is carried out on the top of the frame. The structural frame is rigidly connected with the wall of the original building, so that the structural frame not only damages the wall of the original building, but also is not beneficial to earthquake resistance. And the structure of the outer sleeve frame is complicated, the lighting of the original building is seriously influenced, the construction difficulty is high, and the construction period is long.
Disclosure of Invention

The invention also aims to provide a construction method of the short-limb shear wall frame structure added with floors in the existing building.
The technical scheme of the invention is as follows: a plurality of shear walls are symmetrically arranged on two sides of an 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 connecting beams are connected through cross beams to form a beam body framework.
As a further improvement of the invention, the shear walls are arranged along the length direction of the existing building.
As a further improvement of the invention, a gap is formed between the shear wall and the outer wall of the existing building, which is beneficial to earthquake resistance.
As a further improvement of the invention, the lower end of the shear wall is provided with a foundation, and the foundation is positioned below the ground.
As a further improvement of the invention, the beam frame is provided with at least two layers.
A construction method of a short-limb shear wall frame structure for adding floors to an existing building comprises the following steps:
A. symmetrically constructing foundations on two sides of an existing building, and constructing shear walls on the foundations;
B. constructing connecting beams between the corresponding shear walls, wherein the connecting beams are suspended above the existing building;
C. after the construction of the connecting beams is finished, the connecting beams are perpendicular to the connecting beam construction crossbeam, and the crossbeam connects a plurality of connecting beams into a whole to form a beam body framework.
The invention has the beneficial effects that: the invention arranges the independent shear wall at the side part of the existing building, the shear wall is not connected with the existing building, the wall surface of the existing building cannot be damaged during construction, the bottom of the shear wall is provided with the foundation below the ground, the wall body is stable, the upper end of the shear wall extends to the top of the existing building, the connecting beam and the crossbeam are arranged above the top of the existing building, and multiple layers can be added on the existing building. The short-limb shear wall frame structure is mutually independent from the existing building, and a reasonable gap is reserved between the shear wall and the existing building to serve as an anti-seismic seam, so that the anti-seismic structure is facilitated. The invention has simple structure, no complex frame structure, small influence on the lighting of the existing building, simple construction method and short construction period.
