Description
Technical Field
The utility model relates to the technical field of building storey adding transformation, in particular to an exposed steel frame of an existing building storey adding layer.
Background
With the increasing of urban population, house pressure in towns is increasing, and in order to relieve house pressure, houses are increased on the premise of not dismantling the existing building, and layering is generally carried out on the existing building. The building roof is flattened on the basis of the original building, a new floor is built on the flattened building roof, and a new housing area is added.
At present, when an existing building is built, in order to ensure that the surface of a newly added floor and the surface of the existing building can be in flush transition, the newly added floor and the existing building can be more integrated, and no large difference exists. Therefore, in actual construction, the newly added storey is mostly fixedly connected to the existing building by using the reinforcing steel bar frame, and in order to prevent the excessively large pressure of the newly added storey on the existing building, the reinforcing steel bar frame used by the newly added storey is generally selected as light steel so as to reduce the total weight of the newly added storey, so that the number of newly added storeys is small. However, if a large vehicle passes by the building to generate slight vibration on the ground, the vibration is transmitted to the newly added floor through the ground and the original building, and the stability of the newly added floor is poor while the original building is stable due to the light weight of the newly added floor, so that a certain potential safety hazard exists.
Therefore, the conventional concrete frames for newly added floors on existing buildings are less safe when the number of newly added floors is small.
