Description
Technical Field
The utility model relates to a building reinforcement field especially relates to a newly-increased shear wall structure for building old frame is consolidated.
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 newly-increased shear wall structure for building old frame is consolidated, this structure is through newly-increased wall of establishing to building old frame post, and newly-increased shear wall structural rigidity is strong, attaches to be connected and the anti-shear capacity that adds muscle ability reinforcing and former structure, and simple structure, construction convenience.
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 comprises original frame columns, a newly-added shear wall reinforcing mesh, tie bars, additional bars and a newly-added shear wall; the original frame column is of an original building frame supporting column structure, and a newly-added shear wall reinforcing mesh is embedded at one side of the original frame column; the newly-added shear wall reinforcing mesh is formed by mutually lapping transverse ribs and longitudinal ribs, wherein one ends of the transverse ribs are embedded into the original frame columns and are welded and connected with the longitudinal ribs in the original frame columns, the two newly-added shear wall reinforcing meshes are separated by a certain distance, and tie bars are welded and connected between the two newly-added shear wall reinforcing meshes; the tie bar is of a steel bar structure with two hooked ends; an additional rib is embedded between two newly-added shear wall reinforcing steel bar nets on one side of the original frame column, one end of the additional rib is embedded into the original frame column, and the other end of the additional rib extends horizontally in a hook shape and is welded and connected with the tie rib; and the newly-added shear wall is poured on a reinforcing mesh frame formed by the reinforcing mesh, the tie bars and the additional bars of the newly-added shear wall.
Preferably, the additional ribs are of a steel bar structure with the diameter of 12mm, and the vertical distance between the additional ribs is 400 mm.
The utility model has the advantages that: this structure is through newly-increased wall of establishing to building old frame post, and newly-increased shear wall structural rigidity is strong, attaches the enhancement of muscle ability and the anti-shear capacity of being connected with original structure, and simple structure, construction convenience.
