Abstract
The invention discloses a reinforcing steel bar with a segmentation mark. The reinforcing steel bar comprises transverse ribs, a conventional mark symbol and the segmentation mark; the segmentation marks are respectively labeled at gaps between the transverse ribs on the surfaces of the different reinforcing steel bars; the segmentation mark is a point or a line; and the height of the segmentation mark is lower than those of the transverse ribs. According to the reinforcing steel bar with the segmentation mark, the segmentation marks are respectively labeled at the gaps between the transverse ribs on the surfaces of the different reinforcing steel bars, so that a reinforcing steel bar quality control personnel can accurately distinguish the different reinforcing steel bars, and a rolling mill is rapidly adjusted when the sizes and the mechanical properties have the significant differences; and therefore, the quality fluctuation is reduced, and the product qualification rate is improved.
Description
Technical field
The present invention relates to a kind of reinforcing bar, more specifically, relate to a kind of reinforcing bar with cutting sign.
Background technology
Requirement to surface quality among the screw-thread steel standard GB 1499.2-2007 " steel concrete steel part 2: hot rolled ribbed steel bar " is: " reinforcing bar should not have harmful surface blemishes; The weight, size, cross-sectional area and the tensile property that need only the sample of brushing through wire brush are not less than the requirement of standard, and scale, surface irregularity or iron scale be not as the reason of rejecting ".
In the testing process of reinforcing bar, after quality control personnel check out quality problems, be difficult to accurate orientation problem and go out at any root reinforcing bar place, can not the rapid adjustment milling train, make quality fluctuation big, product percent of pass is low.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides a kind of accurate differentiation different root reinforcing bars, and the rapid adjustment milling train improves the reinforcing bar with cutting sign of product percent of pass.
In order to solve above technical problem, the invention provides a kind of reinforcing bar with cutting sign, comprise cross rib and conventional identifier, also comprise the cutting sign, described cutting marks the cross rib gap location in different root rebar surfaces.Described conventional identifier comprises the trade mark, factory's name or trade mark, specification etc.
The technical scheme that the present invention further limits is: described cutting is designated point-like or wire.
Further, the height of described cutting sign is lower than the height of described cross rib.
Further, described reinforcing bar is screw-thread steel.
Further, described screw-thread steel is the screw-thread steel of the rolling φ 10 ~ φ 22mm of three cutting technologies or two cutting technologies.
The invention has the beneficial effects as follows: a kind of reinforcing bar with cutting sign of the present invention, cross rib gap location mark cutting sign at different root rebar surfaces, be that the steel bar quality inspection personnel can accurately distinguish different root reinforcing bars, rapid adjustment milling train when significant difference appears in size and mechanical property, reduce quality fluctuation, improve product percent of pass.
Description of drawings
Fig. 1 is the structural representation with reinforcing bar of cutting sign of the present invention.
The specific embodiment
Embodiment 1
A kind of reinforcing bar with cutting sign that present embodiment provides, its structural representation comprise cross rib 1, conventional identifier 2 and cutting sign 3 as shown in Figure 1.
Reinforcing bar is screw-thread steel, and described screw-thread steel is the screw-thread steel of the rolling φ 10 ~ φ 22mm of three cutting technologies or two cutting technologies, and adopting the screw-thread steel of the rolling φ 10mm of three cutting technologies in the present embodiment is example.
Cross rib 1 arranges along the screw-thread steel spiral, increases the bond stress of screw-thread steel in concrete.
Conventional identifier 2 comprises the trade mark, factory's name or trade mark, specification etc., and the double thread steel identifies.
The cutting sign 3 cross rib gap locations that mark in different root rebar surfaces, and at the front and back position of conventional identifier.Cutting sign 3 must make a distinction with conventional identifier 2, so cutting sign 3 is point-like or wire.In the present embodiment, cutting sign 3 is wire.And for check and the use that does not influence screw-thread steel, the height of cutting sign 3 is lower than the height of described cross rib.
A kind of reinforcing bar with cutting sign of the present invention, cross rib gap location mark cutting sign at different root rebar surfaces, make the steel bar quality inspection personnel can accurately distinguish different root reinforcing bars, rapid adjustment milling train when significant difference appears in size and mechanical property, reduce quality fluctuation, improve product percent of pass.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
Claims (5)
