Assembled frame system with concrete filled steel tube branch limb combined special-shaped column and shock absorption wall

Abstract

The invention discloses an assembled frame system with a concrete filled steel tube branch limb combined special-shaped column and a shock absorption wall and belongs to the field of building structure techniques and earthquake resistance and shock absorption of structures. The system primarily comprises a round concrete filled steel tube long column welded steel batten plate, and a prefabricatedcorner column, a prefabricated side column, a prefabricated middle column, a reinforced concrete beam, a steel plate wall, a prefabricated steel floorslab, a column-column connecting sleeve, a column-beam anchoring part, a middle column-beam anchoring part, a beam-plate connecting part, ECC post-cast strips and the like prepared by pouring concrete outside. Upper and lower concrete filled steel tubes are connected through the column-column connecting sleeve, and the column-beam anchoring part, the middle column-beam anchoring part and the round concrete filled steel tube long column are connected and prefabricated through dowels, so that the beam-column node connecting performance is enhanced. The ECC post-cast strips are arranged at two ends of the beam and the wall and are poured up anddown in a penetrating manner, so that the energy consumption ability and the anti-earthquake performance of the structural system are improved. The assembled frame system achieves the functions of hiding column edges and being attractive in building, a project is simple and rapid to construct, the construction efficiency is high, the nodes are connected stably and reliably, and the structural system is good in anti-earthquake performance.

Description

technical field [0001] The invention relates to an assembly frame system with a special-shaped column combined with steel pipe concrete split limbs and a shock absorbing wall, and belongs to the field of new building structure technology and structural shock resistance and shock absorption. Background technique [0002] Special-shaped column refers to a column whose cross-sectional geometry is L-shaped, T-shaped, cross-shaped or straight, and the ratio of limb height to limb thickness of each limb of the cross-section is not greater than 4. The special-shaped column frame system is a frame system in which special-shaped columns replace traditional rectangular columns as vertical support components. The thickness of column limbs, beam width, and wall thickness are the same, and the building is beautiful. With the deepening of research, more and more researches have been obtained. Promote apps.

AI Technical Summary

Problems solved by technology

Because special-shaped columns are limited by limb thickness ratio and section size, and affected by concrete strength and reinforcement ratio, the bearing capacity of reinforced concrete special-shaped columns is low, the limit value of axial compression ratio is too low, and the seismic performance is not ideal. limit
