Embodiment 1

[0029] refer to figure 1 and figure 2 , the size of the concrete blocks in this embodiment is 390mm×190mm×190mm; the block masonry wall 2 has structural columns 3 and ring beams (1, 4), and the block masonry wall 2 has a length of 4.2m and a height of 3m, thickness 240mm; structural column 3 has a cross-sectional dimension of 120mm×240mm; ring beam 1 has a cross-sectional dimension of 340mm×400mm; ring beam 4 has a cross-sectional dimension of 180mm×240mm; high ductility fiber concrete core column 7 has a cross-sectional dimension of 120mm × 120mm, the spacing along the wall is 2m; the structure of the high ductility fiber concrete composite block masonry wall of this embodiment is: a number of short steel bars 5 are buried in the vertical mortar joints of the block masonry wall 2; The outer surface of the block masonry wall 2 is coated with a high-ductility fiber concrete surface layer 6 ; a high-ductility fiber concrete core column 7 is poured inside the block masonry wall...

Embodiment 2

[0042] refer to image 3 with Figure 4 , the size of the concrete block in this embodiment is 390mm×190mm×190mm; the block masonry wall 2 has no structural column, the block masonry wall 2 has a length of 4.2m, a height of 3m, and a thickness of 240mm; ring beam 4 The section size of the high ductility fiber concrete core column 7 is 150mm×150mm, and the spacing along the wall is 2m; the other construction procedures are the same as in the first embodiment.

[0043] The present invention utilizes the advantages of the mechanical properties of high ductility fiber concrete and the good viscous performance with the block masonry wall, which not only produces a large lateral active restraint force on the block masonry wall, but also improves the shear resistance of the block masonry wall Strength, pouring high ductility fiber concrete core columns inside the block masonry wall can prevent the block masonry wall from being partially crushed, improve the integrity of the block ma...

Abstract

The invention discloses a high-ductility fiber concrete combination block masonry wall and a construction method thereof, and solves the problems of fragility, poor anti-seismic property and poor integrity of the conventional common block masonry wall. The high-ductility fiber concrete combination block masonry wall comprises a block masonry wall, a short reinforcing steel bar, a high-ductility fiber concrete core column and a high-ductility fiber concrete pavement; the construction method comprises the following steps of: during construction, firstly, building a common block masonry wall, and embedding the short reinforcing steel bar in a vertical mortar joint of the wall; secondly, pouring the high-ductility fiber concrete core column into the built block masonry wall; and at last, smearing high-ductility fiber concrete on the surface of the wall. The block masonry wall, provided by the invention, has the advantages of better compressive capacity, shearing resistance and anti-seismic property than the conventional block masonry wall, difficulty in having brittle failure, simple construction and lower construction cost.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a high ductility fiber concrete composite block masonry wall and a construction method thereof. Background technique [0002] The block masonry structure is mainly made of blocks and mortar. The construction quality varies greatly, the strength is relatively low, and the discreteness is large. Its tensile, shear and flexural bearing capacity are all low. After the block masonry wall cracks in the earthquake, its bearing capacity drops rapidly, and it is easy to collapse, causing huge casualties and serious economic losses in the earthquake area. The block masonry structure is widely used in our country, so the research work on the block masonry structure is particularly important. It is found from macroscopic earthquake damage and experimental research that the cracking and collapse of block masonry walls under earthquake action is mainly due to the insuffi...
