Problems solved by technology

The seismic damage investigation results of the Wenchuan Earthquake show that the filling wall has a large lateral stiffness and bears a large earthquake action, but the deformation capacity of the wall itself is poor, which makes the filling wall severely damaged and even collapsed, causing casualties and serious economic losses

Embodiment 1

[0026] refer to figure 1 with figure 2 , The dimensions of the high ductility fiber concrete composite frame filled wall in this embodiment are as follows: the length is 4.2m, the height is 3m, and the thickness is 240mm. Several short steel bars 4 are buried in the vertical mortar joints of the frame-filled wall; the outer surface of the frame-filled wall 3 is coated with a 20mm thick high-ductility fiber concrete surface layer 5, and the high-ductility fiber concrete surface layer 5 fills the frame Wall 3 and all short bars 4 cladding. Its specific construction process is:

[0027] Step 1, build the frame filling wall 3, and embed the short steel bars 4 of the shear connectors in the vertical mortar joints of the frame filling wall; the horizontal spacing and the vertical spacing of adjacent short steel bars are both 300mm; the diameter of the short steel bars 4 used 12mm, length 120mm, protruding 20mm from the surface of the brick wall;

[0028] Step 2: Evenly apply a ...

Abstract

The invention discloses a high-elongation fiber concrete combined frame filled wall and a construction method thereof so as to solve the problem that the conventional common frame filled wall has fragility, low seismic resistance and low integrity. The high-elongation fiber concrete combined frame filled wall consists of a frame filled wall, short steel bars and high-elongation fiber concrete; and the construction method comprises the following steps of: during construction, building the frame filled wall, embedding a plurality of short steel bars into vertical mortar joints of the frame filled wall; and uniformly daubing the high-elongation fiber concrete on the surface of the frame filled wall. The seismic resistance, collapse resistance and deformation resistance of the frame filled wall are superior to those of the traditional frame filled wall, and brittle failure of the frame filled wall is difficult to occur; and meanwhile, according to the frame filled wall, partial seismic energy is consumed by utilizing the filled wall, so that the seismic damage of the frame is lightened, and the construction process is simple.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a high ductility fiber concrete composite frame filling wall and a construction method thereof. Background technique [0002] Reinforced concrete frame structure is a lateral force-resistant structure widely used in hotels, schools, office buildings and other buildings. Frame infill walls are enclosure walls and partition walls of frame structure houses, generally non-load bearing brick masonry walls. The seismic damage investigation results of the Wenchuan Earthquake show that the filling wall has a large lateral stiffness and bears a large earthquake action, but the deformation capacity of the wall itself is poor, which makes the filling wall severely damaged and even collapsed, causing Casualties and serious economic losses. In our country, the frame structure is widely used. From the macro-seismic damage and experimental research, it is found that the cracking and...
