Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings.

[0017] The SMC-FRP-concrete composite column of the present invention includes concrete columns, poured FRP bars and FRP plates, and outsourced SMC moulds; the joints of the FRP plates are fixed by sealing corners; the inside of the SMC molds is provided with internal ribs and processed by sticking sand. The SMC tube is placed inside the FRP plate to increase the three-way compression of the composite column. In the production process of SMC-FRP-concrete composite column, firstly, the SMC composite material molding mold is used as the composite column mold; then the bound and fixed FRP cage, the FRP plate whose connection part is fixed by sealing corner, and the SMC casing are placed in the mold in sequence Interior; final pour of concrete. Concrete includes ordinary concrete, recycled concrete, self-compacting concrete, and fiber concrete. ...

Abstract

The invention discloses an SMC-FRP-concrete combination column and relates to a building member. The concrete combination column comprises a concrete column body, FRP bars, FRP plates and an SMC mould which is enclosed outside, wherein the FRP bars and the FRP plates are poured in the concrete column body. The connecting parts of the FRP plates are fixed with sealing angles; inner ribs are arranged on the inner side of the SMC mould subjected to sand binding; an SMC sleeve is arranged inside the FRP plates; the SMC composite material mould pressing mould is a combined column mould; and a bound FRP bar cage, the FRP plates with the connecting parts being fixed with the sealing angles and the SMC sleeve are placed inside the mould sequentially and are filled with concrete. The concrete combination column utilizes the advantages of lightweight, high strength and corrosion prevention of FRP composite materials and SMC composite materials and is suitable for the intensive corrosion environment of coastal and insular cities; and the SMC mould has high plasticity, a manufactured finished product is attractive in appearance, the process is simple, meanwhile, in the construction process, the formwork engineering is reduced, and resource energy consumption is reduced.

Description

technical field [0001] The invention relates to a building component, in particular to an SMC-FRP-concrete composite column. Background technique [0002] With the development of the civil engineering industry and the increase of building height and bridge span, composite columns have received attention and research in the engineering field, which mainly include steel tube concrete composite columns and composite steel tube concrete composite columns. Although the composite column has exerted great advantages in the engineering structure, there is still room for improvement in terms of materials and combination forms. [0003] In actual engineering, especially in severe cold areas and coastal areas, the durability and structural stability of infrastructure caused by steel corrosion has not only brought huge economic losses, but also caused serious safety hazards to people's lives. In recent years, the emergence of SMC composite materials and fiber composite materials has gr...
