Continuous trepanning type steel folded plate connecting device and manufacturing method

Abstract

The invention discloses a continuous trepanning type steel folded plate connecting device and a manufacturing method. The continuous trepanning type steel folded plate connecting device comprises a base, at least two first folded plates and two second folded plates, the first folded plates and the second folded plates are fixed to the base, and all the first folded plates are located between the two second folded plates; the two adjacent first folded plates are connected through corresponding first steel bars, and the second folded plates and the adjacent first folded plates are connected through corresponding first steel bars. The first folded plate comprises a first flat plate, a second flat plate and a third flat plate, the first flat plate and the third flat plate are arranged in parallel, the two ends of the second flat plate are connected with the first flat plate and the third flat plate respectively, and the second flat plate is connected with the base. The space staggering degree of the connecting device is higher, after concrete is poured, the first folded plates are embedded into the concrete, compressed concrete blocks are formed between the adjacent first folded plates, the action area of the first folded plates in the longitudinal shear force direction is large, the compressed concrete blocks with the larger size are formed, and the longitudinal shear bearing capacity of the connecting device is improved.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a connecting device and a manufacturing method of continuous perforated steel folded plates. Background technique [0002] In recent years, with the gradual promotion of the traditional construction industry to develop in a green, efficient and modern direction, prefabricated buildings have been promoted on a large scale, and the development and application of steel-concrete composite structures with excellent mechanical properties have been rapid. The most critical problem in the steel-concrete composite structure is the connection between the steel beam and the concrete slab. Among the existing composite beam shear connectors, the perforated plate connector is one of the main types. The perforated slab connectors are perforated at the proper position of the steel plate, the steel bars are penetrated through the holes, and the poured concrete enters the holes to form a...

Problems solved by technology

[0003] The traditional perforated plate connectors only rely on ordinary concrete tenons to exert the force, and the shear potential of this connector has not been brought into play. Subsequent improved perforated corrugated plate connectors and other forms of corrugated perforated plates developed on this basis Although the plate connectors have increased the pullout and shear resistance of the connectors through different forms of bending structures, they have not fully utilized the potential of this type of connectors.
