Technical Field
The utility model relates to a building reinforcement field especially relates to a consolidate newly-increased shear wall structure of old building frame roof beam.
Background
Many buildings built by adopting old-edition specifications seriously do not meet the requirements of the existing specifications on the earthquake resistance and load of the buildings, are damaged and structurally deformed to a certain extent after being used for a long time and foundation settlement and deformation, and need to be repaired and reinforced to meet the use requirements and ensure the safety of lives and properties. The old building restoration reinforcement engineering needs longer construction cycle, and influences the building normal use in the work progress, if the construction is improper, lead to aggravating the condition such as the building damages or not up to standard after the completion easily moreover and take place.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a consolidate new increase shear wall structure of old building frame roof beam, this structure is consolidated old building frame roof beam through new increase shear wall, and structural rigidity is strong, and antidetonation and bearing capacity satisfy the requirement. And the construction is simple and convenient.
In order to achieve the above object, the utility model adopts the following technical scheme: a newly-added shear wall structure for reinforcing an old building frame beam comprises an original frame beam, a newly-added shear wall reinforcing mesh, connecting ribs and a newly-added shear wall; original floor slabs are built on two sides of the top of the original frame beam, and newly-added shear wall reinforcing mesh is buried in the top surface and the bottom surface of the original frame beam; the bottom end of the newly-added shear wall reinforcing mesh is embedded into the top surface of the original frame beam, and the top end of the newly-added shear wall reinforcing mesh is bent towards two sides and then embedded into the original frame beam on the upper layer; tie bars are arranged between the newly-added shear wall reinforcing steel bar meshes, and two ends of each tie bar are tensioned between the newly-added shear wall reinforcing steel bar meshes on two sides in a hook shape and are welded and connected; the newly-added shear wall reinforcing mesh is welded and connected with additional tie bars at the bending position of the bottom surface of the original frame beam, and the additional tie bars are welded between the newly-added shear wall reinforcing meshes on the two sides; connecting ribs are arranged in the original frame beam, the connecting ribs are arranged in two rows, extend through the original frame beam to a position between the upper layer of newly-increased shear wall reinforcing mesh and the lower layer of newly-increased shear wall reinforcing mesh, the two ends of each connecting rib are in a hook shape, and hook tips of the connecting ribs on the two sides are opposite; and the newly-added shear wall is poured on the newly-added shear wall reinforcing mesh and the connecting ribs.
Preferably, a slope part corresponding to the bent part of the reinforcing mesh of the newly-added shear wall is arranged between the bottom surfaces of the original frame beams at the top end of the newly-added shear wall, and the slope ratio of the slope part is 6: 1.
the utility model has the advantages that: this structure is consolidated old building frame roof beam through newly-increased shear force wall, and structural rigidity is strong, and antidetonation and bearing capacity satisfy the requirement. And the construction is simple and convenient.
