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...
