The mechanical property, the deformation property, the fire resistance and the durability of the whole component are improved.
The above technical problem of the present invention can be solved by the following technical solutions:
the steel tube fabric reinforced concrete member comprises a plurality of base plates, wherein a plurality of layers of steel tube columns are arranged on the base plates, node column sleeves which are mutually inserted and sleeved with the steel tube columns are arranged between the upper steel tube column and the lower steel tube column and on the steel tube column on the uppermost layer, and a cross beam which is fixedly connected with the node column sleeves through bolts is arranged between two adjacent node column sleeves. The steel pipe column comprises a steel pipe, a plurality of woven grid layers which are sleeved with the steel pipe are arranged in the steel pipe, and concrete filling layers are arranged in the steel pipe and between the woven grid layers. The concrete filling layer can adjust the fluidity according to the weaving structure and the arrangement mode of the weaving grid layer, and the compactness of the concrete filling layer is ensured.
Preferably, the weaving grid layer is woven into a cylindrical structure, the weaving grid layer comprises weft knitting strips, and the weft knitting strips are provided with knitting strips which are crossed, overlapped and interlaced with the weft knitting strips. The weft knitting strips and the knitting strips are made of fabrics, can be knitted into any form, such as orthogonal grids or orthogonal diagonal grids, can be embedded in any position in the filled concrete, and can be arranged in a grid shape or a tubular shape along the length direction.
