Embodiment 1

[0017] Such as figure 1 As shown, in this embodiment, the cross-sectional size of the brick column in this example is 370mm×370mm, the height of the column is 3.9m, and the blocks are made of solid bricks with a size of 240mm×115mm×53mm. The brick column is built with high ductility mortar, and the thickness of the mortar is 7mm.

[0018] Following the technical solution of the present invention, the components of the high ductility mortar of this embodiment are cement, fly ash, silica fume, sand, PVA fiber and water, wherein, by mass percentage, cement: fly ash: silica fume: Sand: water = 1: 0.9: 0.1: 0.76: 0.58; based on the total volume of cement, fly ash, silica fume, sand and water mixed uniformly, the volume of PVA fiber (polyvinyl alcohol fiber) is 1.5 %; The cement used is P.O.52.5R Portland cement, the fly ash is Class I fly ash, the loss on ignition of silica fume is 5%, the silica content is 88%, and the specific surface area is 18000m 2 / kg, the maximum particle ...

Abstract

The invention discloses a high elongation brick column which solves the problems of fragility, low bearing capacity and poor anti-seismic property in the existing brick columns. Masonry mortar of the high elongation brick column is high elongation mortar, and the high elongation mortar comprises cement, coal ash, silica fume, sand, polyvinyl alcohol (PVA) fiber and water. The anti-seismic property of the high elongation brick column is remarkably better than that of a common brick column. The high elongation brick column is high in strength and good in ductility. Simultaneously the high elongation mortar can restrain damage on bricks, brittle failure of the brick columns is prevented, and energy consumption capacity of a brick masonry structure can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a high ductility brick column. Background technique [0002] At present, brick masonry structures are widely used in the field of industrial and civil buildings in my country, but due to the brittle nature of brick masonry materials, their tensile, shear and flexural strengths are low and their own weight is large, which is extremely unfavorable for structural earthquake resistance. . [0003] Brick columns are one of the most important load-bearing components in brick masonry structures. They bear the vertical loads from floors and beams, and also bear part or all of the horizontal loads. Their seismic performance has a great influence on the safety of masonry structures. The bearing capacity of brick columns may not meet the requirements due to the increased requirements for building anti-seismic fortification, changes in use functions, and structural corrosion damage...
