Embodiment Construction

[0039] see figure 1 , figure 1 It is a cross-sectional view of the FRP pipe-concrete-steel composite pipe tower of the present invention. Such as figure 1 As shown, the FRP pipe-concrete-steel pipe composite pipe tower provided by the present invention is mainly composed of a steel inner pipe 10 formed by connecting multiple steel pipe sections, an FRP outer pipe 20 formed by connecting multiple FRP pipe sections, and pouring between the two Concrete layer 30 in between. It should be noted, figure 1 The steel inner tube 10 and the FRP outer tube 20 are shown as circular, but the two tubes can also be of other shapes (such as square), or different shapes (such as the outer tube is a square tube and the inner tube is a round tube). Both the steel pipe segment and the FRP segment can be prefabricated in the factory, and can also be constructed on the construction site of the FRP pipe-concrete-steel pipe composite tower.

[0040] It is worth mentioning that the adjacent steel...

Abstract

The invention relates to an FRP (fiber reinforce plastic) tube-concrete-steel tube combined tube tower comprising an inner steel tube, an FRP outer tube and a concrete layer, wherein the inner steel tube is formed by connecting a plurality of steel tube segments, the FRP outer tube is formed by connecting a plurality of FRP tube segments, and the concrete layer is poured between the inner steel tube and the FRP outer tube; the adjacent steel tube segments of the inner steel tube are connected by a steel tube adapting piece; the steel tube adapting piece is positioned on the outer surface of the inner steel tube; the adjacent FRP tube segments of the FRP outer tube are connected by an FRP adapting piece positioned on the inner surface of the FRP outer tube; and the steel tube adapting piece and the FRP adapting piece are both embedded in the concrete layer. The invention also provides a segmented construction method for the FRP tube-concrete-steel tube combined tube tower. When the combined tube tower or similar tower-shaped or columnar structure is implemented, long tubes and large prefabricated concrete parts do not need to be transported The combined tube tower has high construction speed, the steel tube adapting piece and the FRP tube adapting piece can also serve as shear keys between the concrete layer and two tubes and the stiffening ribs of two tubes, thus improving thestructural property of the combined tube tower.

Description

technical field [0001] The invention relates to a building and a construction method thereof, more specifically, to an FRP pipe-concrete-steel pipe composite tower and a segmental construction method thereof. Background technique [0002] FRP (fiber-reinforced polymer, fiber-reinforced composite material) tube-concrete-steel tube composite column is a new structural component invented by Professor Teng Jinguang of Hong Kong Polytechnic University. The composite column is composed of FRP outer tube, steel inner tube, and concrete filled between them; the concrete can be equipped with or without steel bars. The direction of the fibers in the FRP outer tube can be designed according to the structural needs. In most applications, the fibers are mainly arranged in the ring direction or close to the ring direction; the steel inner tube has both horizontal and vertical stiffness and bearing capacity. [0003] The FRP outer tube and the steel inner tube may both be circular, rectan...
