Description
Technical Field
The utility model relates to a building reinforcement field especially relates to a reinforced structure of old building frame corner post.
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
The utility model aims to provide a defect and not enough to prior art, provide the reinforced structure of old building frame corner post, this structure is consolidated old building frame end post through newly-increased shear force wall, and structural rigidity is strong, and the construction is simple and convenient, has good antidetonation and load-carrying capacity.
In order to achieve the above object, the utility model adopts the following technical scheme: a reinforced structure of an old building frame corner post comprises an original frame post, a newly-added post reinforcement mesh, a newly-added post, a newly-added shear wall reinforcement mesh and a newly-added shear wall; the original frame column is an existing supporting column structure of an old building, and newly-added column reinforcing steel bar nets are embedded on two adjacent side surfaces of the original frame column; the newly-added column reinforcement mesh consists of an opening stirrup and a longitudinal bar, and two ends of the opening stirrup are embedded into the original frame column and are welded and connected with the longitudinal bar of the original frame column; chiseling part of concrete at the embedded position of the opening stirrup of the original frame column, and arranging and welding the reinforcement between the longitudinal reinforcement of the original frame column and the reinforcement net end of the newly added column; the newly added column reinforcing mesh is provided with a single-limb hoop at the corner part which is not connected with the original frame column, and the single-limb hoop is hooped between two adjacent longitudinal bars in an S shape; newly-added columns are poured and cast on the newly-added column reinforcing mesh, the newly-added columns are of an L-shaped concrete structure, and the end faces of the newly-added columns are flush with the end faces of the original frame columns; the newly added columns are embedded with newly added shear wall reinforcing steel bar meshes, the newly added shear wall reinforcing steel bar meshes penetrate through the newly added columns and are embedded into the original frame columns, additional ribs embedded into the original frame columns are further arranged among the newly added shear wall reinforcing steel bar meshes, and the additional ribs are welded on the newly added column reinforcing steel bar meshes; and the newly-added shear wall is poured and cast on the steel bar net 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 300 mm.
The utility model has the advantages that: the structure reinforces the old building frame end column through the newly-added shear wall, has strong structural rigidity, is simple and convenient to construct, and has good anti-seismic and loading capacity.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention.
Fig. 1 is a schematic view of a structure of a newly added shear wall.
Wherein: 1 is an original frame column, 2 is a newly-added column reinforcing mesh, 21 is a single-limb hoop, 22 is a parallel rib, 3 is a newly-added column, 4 is a newly-added shear wall reinforcing mesh, 41 is an additional rib, and 5 is a newly-added shear wall.
