Abstract

The invention discloses an assembled PVC-FRP tube concrete column-reinforced concrete beam self-resetting annular beam node which comprises a prefabricated PVC-FRP tube concrete column, a prestressedconcrete beam with a pre-stress connecting seat, and a pre-stress connecting seat. The pre-stress connecting seat comprises a circumferential longitudinal rib, a stirrup and a circumferential pre-stress rib. The pre-stress connecting seat is provided with a concrete cushion at the periphery of a node-connecting-position trough. One half of the pre-stress connecting seat enters the node-connecting-position trough. The pre-stress connecting seat connects the circumferential longitudinal rib with the circumferential pre-stress rib through a steel bar sleeve. Cast-in-situ concrete is applied to aconnecting part between the pre-stress connecting seat and the prefabricated PVC-FRP tube and a node connecting part. According to the assembled PVC-FRP tube concrete column-reinforced concrete beam self-resetting annular beam node, through configuring the pre-stress rib at a node position, certain resetting capability of the component is realized, and furthermore bending resistance of the component can be improved. Furthermore a pre-stress which is applied to the node can improve shearing resistance of the node, thereby effectively improving earthquake resistance of the node.

Description

technical field

[0001] The invention relates to the technical field of civil engineering, in particular to an assembled PVC-FRP pipe concrete column-reinforced concrete beam self-resetting ring beam node. Background technique

[0002] At present, construction in our country is dominated by on-site manual wet work, and the degree of industrialization and production efficiency of construction is low, which is a labor-intensive production method. At present, the existing buildings have problems such as unreasonable performance-cost ratio, poor versatility of equipment, long construction period, waste of construction resources, etc., which are no longer suitable for economic development and people's demand for architectural quality under the new situation.

[0003] Prefabricated structure means that prefabricated components are prefabricated in professional factories or construction sites, and the prefabricated components are connected into an integral structure by means of lift...
