Embodiment 1

[0026] refer to figure 1 and figure 2 , the brick wall 2 in this embodiment has structural columns 3 and ring beams (1, 4), and the size of the sintered ordinary bricks is 240mm×115mm×53mm; the length of the brick wall 2 is 4.2m, the height is 3m, and the thickness is 240mm The section size of structural column 3 is 120mm×240mm; the section size of ring beam 1 is 340mm×400mm; the section size of ring beam 4 is 180mm×240mm; A short steel bar 4; the outer surface of the brick wall 1 is coated with a high ductility fiber concrete surface layer 6. Its specific construction process is:

[0027] Step 1: Build the brick wall 2, and embed several short steel bars 5 in the vertical mortar joints of the brick wall 2, and then pour the structural columns 3 and the ring beams 1, 4;

[0028] Step 2: Spread a 20mm thick high ductility fiber concrete surface layer 6 on the surface of the brick wall 2 that has been built, and the high ductility fiber concrete surface layer covers the bric...

Embodiment 2

[0038] refer to image 3 and Figure 4 , the brick wall 2 in this embodiment does not have a structural column, and the size of sintered ordinary bricks is 240mm×115mm×53mm; the length of the brick wall 2 is 4.2m, the height is 3m, and the thickness is 240mm; the cross-sectional size of the ring beam 1 is 340mm × 400mm; other construction procedures are the same as in Embodiment 1.

[0039]The present invention utilizes the advantages of the mechanical properties of high ductility fiber concrete and the good viscous properties with the brick masonry wall, which not only produces a large lateral active restraint force on the brick masonry wall, but also improves the shear strength of the brick masonry wall and It can improve the integrity of the brick masonry wall, effectively inhibit the cracking of the brick masonry wall, greatly improve the deformation capacity of the brick masonry wall itself, thereby significantly improving the stability and seismic performance of the bri...

Abstract

The invention discloses a high-ductility fiber concrete combined brick masonry wall and a method for constructing the same to solve problems of fragility, and poor seismic resistance and wholeness of prior common brick masonry walls. The high-ductility fiber concrete combined brick masonry wall is composed of a brick wall, short rebars and a high-ductility fiber concrete surface layer. During the construction, a masonry wall is constructed, the short rebars are embedded in vertical mortar joints of the brick wall, and the high-ductility fiber concrete is coated on the surface of the brick wall. According to the high-ductility fiber concrete combined brick masonry wall and the method for constructing the same, the compressive capacity, the shearing resistance and the seismic resistance of the brick masonry wall are better than those of a traditional brick wall, and brittle failure is not easy to occur; and simultaneously, the brick masonry wall is simple to construct and low in construction cost.

Description

technical field [0001] The invention belongs to the field of building structures in the field of civil engineering, in particular to a high ductility fiber concrete composite brick masonry wall and a construction method thereof. Background technique [0002] Brick masonry structures are mainly made of bricks and mortar, with large differences in construction quality, relatively low strength, large discreteness, and low tensile, shear and flexural bearing capacities. After the brick masonry wall cracks in the earthquake, its bearing capacity drops rapidly, and it is very easy to collapse, causing huge casualties and serious economic losses in the earthquake area. The brick masonry structure is widely used in our country, so the research work on the brick masonry structure is particularly important. From macroscopic earthquake damage and experimental research, it is found that the cracking and collapse of brick masonry walls under earthquakes is mainly due to the insufficient...
