The frame infilled wall reinforced by the high ductility fiber concrete comprises a horizontal frame beam and a vertical frame column, and the frame infilled wall is arranged between the frame beam and the vertical frame column. The frame infilled wall reinforced by the high ductility fiber concrete is characterized in that a plurality of short steel bars are buried in a vertical mortar joint of the frame infilled wall; a high ductility fiber concrete surface layer is coated on the outer surface of the frame infilled wall, and the high ductility fiber concrete surface layer wraps the frame infilled wall and all the short steel bars. According to the frame infilled wall reinforced by the high ductility fiber concrete, the high ductility fiber concrete surface layer and the short steel bars are used for reinforcing the frame infilled wall, the earthquake resistance performance and the deformation capacity of the frame infilled wall are greatly improved, and brittle fracture of the frame infilled wall is effectively avoided. The frame infilled wall reinforced by the high ductility fiber concrete can be used for the structure of the frame infilled wall in earthquake areas, the earthquake resistance performance and the collapse prevention capacity of infilled walls are improved, the infilled wall is used for consuming part of earthquake energy to lighten the earthquake damage to frame, and the earthquake resistance performance of the structure of the frame is improved.
Description
Technical field
The utility model relates to building structure aseismatic and reinforcing technique field, is specially a kind of high ductility fibrous concrete stiffening frame infilled wall.
Background technology
Reinforced concrete frame structure is a kind of lateral resisting structure that is widely used in the buildings such as hotel, school, office building.Frame wall filled with masonry is enclosure wall and the partition wall of framework house, generally is nonbearing wall.The seimic disaster census result of Wenchuan earthquake shows, because infilled wall has larger lateral rigidity, has born larger geological process, but the deformability of body of wall itself is relatively poor, make the destruction of infilled wall serious, even collapse, cause casualties and serious economic loss.Application in China's frame construction is quite extensive, therefore the reinforcement of frame wall filled with masonry is seemed particularly important.Find from macroscopical earthquake and experimental study, the cracking of geological process underframe infilled wall and collapsing is not enough mainly due to shear strength and the deformability of frame wall filled with masonry.
Frame wall filled with masonry reinforcing technique commonly used has Enlargement of Section, outsourcing shaped steel method and steel mesh reinforcement surface layer reinforcing method etc.Above-mentioned reinforcement and strengthening technology integral level is relatively backward, and job practices and technique more complicated are not obvious to the stress performance raising of reinforcing the afterframe infilled wall, and reinforcement cost is higher.Therefore, need to seek a kind of reinforcement means that can effectively improve anti-seismic performance, the especially deformability of frame wall filled with masonry, to avoid geological process underframe infilled wall generation brittle fracture.
Summary of the invention
defective or deficiency for the prior art existence, the purpose of this utility model is, the frame wall filled with masonry that provides a kind of high ductility fibrous concrete to reinforce, this frame wall filled with masonry adopts the high ductility fibrous concrete of higher-strength and toughness to form parcel to frame wall filled with masonry, carry out internal reinforcement by bar dowel again, both frame wall filled with masonry was produced larger horizontal active restraint forces, improve the shear strength of frame wall filled with masonry, can improve the globality of frame wall filled with masonry again, effectively suppress the cracking of frame wall filled with masonry, greatly improve the deformability of frame wall filled with masonry self, thereby significantly improve globality and the anti-seismic performance of frame wall filled with masonry, effectively alleviate the destructiveness of geological process underframe infilled wall.The utlity model has that kind of consolidation effect is good, construction is simple and the low advantage of cost.
In order to achieve the above object, the utility model adopts following technical scheme:
The frame wall filled with masonry that a kind of high ductility fibrous concrete is reinforced, comprise horizontal Vierendeel girder, vertical frame column, between described Vierendeel girder and vertical frame column, frame wall filled with masonry is set, it is characterized in that, be embedded with some bar dowels in the frame wall filled with masonry perpends; Be coated with high ductility fibrous concrete surface layer at the frame wall filled with masonry external surface, described high ductility fibrous concrete surface layer coats frame wall filled with masonry and all bar dowels.
The utility model also has following other technologies feature:
Level interval and longitudinal pitch between adjacent bar dowel are 300mm, and the diameter of bar dowel is 10mm.
The thickness of described high ductility fibrous concrete surface layer is 20 ~ 40mm.
Compared with prior art, the utlity model has following characteristics:
(1) the utility model is implanted into bar dowel in frame wall filled with masonry body perpends, and both convenient construction, can strengthen again the adhesive property between frame wall filled with masonry and high ductility fibrous concrete surface layer, guarantees frame wall filled with masonry and surface layer co-operation.
(2) the high ductility fibrous concrete of the utility model employing is a kind of ecological architectural material with high strength, high ductility, high-durability and high damnification resistant ability.Can effectively avoid frame wall filled with masonry generation brittle fracture, significantly improve globality and the anti-seismic performance of frame wall filled with masonry.
(3) the high ductility fibrous concrete of the utility model employing, can give full play to its effect of contraction, better economy, and surface thickness is thinner, and less on the impact of original structure.
