Description

A kind of steel bar cold rolling flatting apparatus

Technical field

The utility model relates to the cold worked plant equipment of a kind of reinforcing bar secondary, is specially a kind of steel bar cold rolling flatting apparatus.

Background technology

Reinforcing bar refers to the steel used with prestressed reinforced concrete that armored concrete is used, and its cross section is circular, is square with fillet sometimes, comprises plain bar, Ribbed Bar, twisted bar.Concrete reinforcement steel refers to vertical bar or the wire rod shape steel that the armored concrete arrangement of reinforcement is used, its profile is divided into two kinds of plain bar and deformed bars, reinforcing bar mainly bears tension in concrete, in fact plain bar is exactly little round steel and the dish circle of ordinary low-carbon steel.Deformed bar is surface reinforcing bar with ribbing, and usually with the vertical rib in 2 roads and equally distributed cross rib along its length, the profile of cross rib is 3 kinds of spiralitys, herringbone, crescent.Deformed bar is because the effect of rib, and concrete has larger cementitiousness, thereby can bear better the effect of external force.Reinforcing bar is widely used in various building structure, particularly the structure of large-scale, heavy, light thin wall and skyscraper.

In the middle of construction, the one-level steel is light face round steel, and concrete friction is good not, so the end must bend when construction, to strengthen reinforcing bar and concrete active force, can better become one.But in the operation of reinforcing steel implant, because the restriction of hole, the plain bar of one-level can't bend the termination, for ganoid plain bar, greatly reduce with respect to the spiral anti-pulling frictional force that mechanical teeth space is arranged after the bar planting, pull-out test can not meet the demands; Artificial twisted bar when the workman constructs simultaneously makes the rebar surface of implantation produce moment of torsion, and plain bar torque resistant ability is far smaller than the spiral of mechanical teeth space; And in time nobody the effect of moment of torsion will inevitably occur for reversing in engineering entity loading process, and is destroyed all easily make reinforcing steel implant when the termination of plain bar does not process after; When the termination pound flat after, plain bar forms mechanical teeth space, the torque resistant ability improves greatly, has guaranteed the rebar-planting quality of reinforcing bar, better serves the engineering entity; Because end and concrete contact area increase, greatly increase anti-pulling frictional force simultaneously.But the termination of existing plain bar is all flat by manually pounding, and not only inefficiency, and labour intensity is large, pounds flat degree varies, quality and the speed of impact construction.
