Steel sleeve

Abstract

The utility model discloses a steel sleeve, including supporter, an elastic component, the 2nd elastic component, firstly press down that the spheroid is pressed down to spheroid, second, the fastener is widened to the first fastener, second widened, the third is widened fastener, fourth and is widened fastener, first cap spare, second cap spare, first cap spare and second cap spare pass through the supporter to be connected, and the intermediate position that props internal portion is equipped with the partition wall, one side the partition wall set up the first chamber that holds, the another side sets up the second and holds the chamber, the first fastener of widening is widened the fastener with the second and is connected to the setting is in first cap spare, and the fastener is widened to the third and the fastener connection is widened to the fourth, and sets up in second cap spare. The utility model discloses two reinforcing bars are cliied two piece back reinforcing bars separately in through first cap spare and second cap spare and are connected on same sharp position to shorten steel bar connection's operating time, improved work efficiency greatly.

Description

technical field [0001] The invention relates to a sleeve, in particular to a steel bar sleeve. Background technique [0002] Generally, according to the structure of the building plan building installation formwork in its mold to construct the building of beams, walls, columns, etc., and reinforce the reinforcement (reinforcement) period after the concrete is cured for a period of time to complete the reinforced concrete structure by stripping (deformation) . [0003] With rebar reinforcement as is the two add up to more tensile or induced bending moments, circular reinforcement etc compressive stresses have relief on the surface of the joints and ribs rebar and no word on the surface, the length is constant between approximately 3.5-10m Standard it produces, a length greater than the width and height of the formwork attached to the reinforcement die in a plurality of short post which are subsequently connected to one or more reinforcements. In this case, the task of conne...

Problems solved by technology

[0007] This traditional technique locates each collinear coupler through connecting to two rebars, but this unites, unites the other side of the cover and reinforces, passing through the rebars and integrating with the rebar sleeve has the problem of falling
