Conical barrel clamping piece type rebar connecting piece

Abstract

The invention relates to the technical field of rebar connecting and fixing in constructional engineering, in particular to a conical barrel clamping piece type rebar connecting piece. The conical barrel clamping piece type rebar connecting piece comprises a first conical barrel, a second conical barrel, a first clamping piece, a second clamping piece and a third clamping piece. The conical barrelclamping piece type rebar connecting piece is formed by splicing the first conical barrel, the second conical barrel, the first clamping piece, the second clamping piece and the third clamping piece,the mounting mode is simple, the structure is firm, and the quality is stable; straight holes and conical holes are formed inside the first conical barrel and the second conical barrel, lateral clamping grooves are formed in the side walls of one ends of the first conical barrel and the second conical barrel, a first clamping piece structure, a second clamping piece structure and a third clampingpiece structure are fixed between a rebar and the conical barrels by using mutual meshing of splicing sawtooth grooves in the lateral clamping grooves in the first conical barrel and the second conical barrel, a cylindrical extrusion mechanism is formed at the rebar connecting end through arc-shaped meshing racks in the clamping pieces and pressed into the surface of the rebar, and the connectingfirmness between the rebar and the connecting surface of the rebar is improved.

Description

technical field [0001] The invention relates to the technical field of connecting and fixing steel bars in construction engineering, in particular to a cone-clamp clip-type steel bar connecting piece. Background technique [0002] Rebar refers to the steel used for reinforced concrete and prestressed reinforced concrete, whose cross section is circular, sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. Steel bars for reinforced concrete refer to the straight or coiled steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar. The delivery state is straight bar and coiled round. Light round steel bars are actually small round bars and discs of ordinary low carbon steel. Deformed bars are ribbed bars on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral, herringbon...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, provide an improved conical tube clip-type steel bar connector, which is different from the threaded clip-type steel bar connection, and is more suitable for hydraulic construction Higher efficiency, solves the problem of simple fixation in the current method of steel bar connection, the connection mechanism is large in size, poor in assembly stability and very limited in firmness, and at the same time the sealing of the steel bar connection end is poor, the safety and quality stability are not high, and the installation quality is not easy Check and other issues
