PVC-FRP pipe restrained section steel concrete column-reinforced concrete beam T-shaped node

Abstract

The invention discloses a PVC-FRP pipe restrained section steel concrete column-reinforced concrete beam T-shaped node which comprises the components of a PVC-FRP pipe, circular steel tube fasteners,core section steel, U-shaped hidden brackets, a column longitudinal rib, a column tie-rib, a beam longitudinal rib, a beam tie-rib, high-strength bolts, core-passing anchor bolts and a stiffening ribplate. The PVC-FRP pipe sleeves the core section steel. Three sets of U-shaped hidden brackets are distributed in a T-shape. The flange of the section steel is connected with the U-shaped hidden brackets through the high-strength bolts. The circular steel tube fastener is connected with the U-shaped hidden brackets through the high-strength bolts. The beam longitudinal rib is welded and anchored with a section steel web plate through the stiffening rib plate. The column tie-rib passes through the U-shaped hidden bracket and is bond with the column longitudinal rib. The PVC-FRP pipe restrainedsection steel concrete column-reinforced concrete beam T-shaped node has advantages of reasonable structure design and simple node structure. Steel components in the node can be directly assembled andfixed by the high-strength bolts. Placement of an annular steel par which restrains the core region of the node is not required in the node area is not required. A purpose of strong node can be realized through a restraining action of the peripheral circular steel pipe fasteners to the node concrete.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a PVC-FRP pipe-constrained steel concrete column-reinforced concrete beam T-shaped joint. Background technique [0002] At present, the traditional construction methods in my country are mainly on-site wet work. During the construction process, there are disadvantages such as complex on-site production, many manual operations, and serious waste of materials, which lead to problems such as low construction production efficiency, long cycle time, and high cost. Therefore, the traditional civil engineering construction mode can no longer meet the needs of modern building development. [0003] The prefabricated structure is a structure that is assembled and connected with prefabricated components as the main force-bearing components. The prefabricated structure is one of the important directions of the development of my country's building structure. It is conducive to the ...
