Problems solved by technology

[0004] The above-mentioned first two types of joints are complex in structure, difficult to pour, and have the disadvantages of local failure of the column that reduces the bearing capacity
And because there is no steel bar in the new beam (FRP is used instead of steel bar to bear the tensile force), it is not suitable for the node connection of the new prefabricated structural system represented by the FRP tubular concrete column with embedded FRP profile and the box-shaped FRP profile concrete composite beam.
Also because there is no steel in the new rapid assembly structure system, the third type of joint connection (welding and bolting) is not applicable

Abstract

The invention discloses a self-locking fiber reinforced polymer (FRP) profile beam-column joint capable of being fabricated quickly. The self-locking FRP profile beam-column joint comprises a circularFRP tube concrete column, box-groove-shaped FRP profile concrete composite beams, a prefabricated joint, matching bolts and clamping pieces; and the joint is connected with the circular FRP tube concrete column through an outer sleeve, the joint is connected with the box-groove-shaped FRP profile concrete composite beams in a socket mode, and is then anchored through bolts. The self-locking FRP profile beam-column joint includes the main construction steps that the circular FRP tube concrete column is manufactured; the box-groove-shaped FRP profile concrete composite beams are manufactured; and the joint is installed on site. According to the fabricated joint, compared with common beam-column joints, the advantages of easy and convenient construction, clear force transmission, no damage to the original column and the like are achieved.
