Fiber reinforce plastic (FRP) combination structure frame where integral type node is adopted and construction method thereof

Abstract

The invention relates to a fiber reinforce plastic (FRP) combination structure frame where an integral type node is adopted and a construction method thereof. The FRP combination structure frame where the integral type node is adopted is formed by enabling an FRP pipe concrete combination beam and FRP pipe concrete combination columns to be connected. The FRP pipe concrete combination beam is horizontally arranged between the FRP pipe concrete combination columns, and the FRP integral type node is fixedly connected at the junction of the FRP pipe concrete combination beam and the FRP pipe concrete combination columns. The FRP integral type node is formed by enabling two node single bodies to be in butt joint and then be fixedly connected through bolts, each node single body is integrally formed after a vertical half pipe and a horizontal half pipe are joined, two longitudinal end faces of the vertical half pipe respectively extend outwards to form connecting lugs, and the upper end face and the lower end face of the vertical half pipe respectively extend outwards to form horizontal column connecting pieces. Two horizontal end faces of the horizontal half pipe respectively extend outwards to form connecting lugs, and the left end face and the right end face of the horizontal half pipe respectively extend outwards to form beam column connecting pieces. Steel ribs can be added in FRP pipes of the frame beam and the columns, or prestressed ribs are arranged in the beam, and bearing capability and rigidity of a component can be improved.

Description

1. Technical field:

[0001] The invention relates to a frame structure in the field of civil and architectural structures, in particular to an FRP composite structure frame using integral nodes and a construction method thereof. 2. Background technology:

[0002] In existing frame structures or structural systems composed of frames and other load-bearing structures, frame nodes are mostly reinforced concrete cast-in-place nodes or composite structure cast-in-place nodes, and composite structure cast-in-place nodes include steel reinforced concrete nodes and steel pipe concrete nodes. Ordinary reinforced concrete and reinforced concrete joints are the same as frame beams and columns, requiring on-site formwork, binding steel bars or welding steel frames, and then pouring concrete. The bearing capacity and stiffness of the components are relatively low, and the construction period is long. With the rapid development of the civil construction industry, concrete-filled steel tube...
