Abstract
The utility model relates to an epoxy steel bar with ribs on three surfaces. The epoxy steel bar is applied to fields of cross-sea bridges, high-speed railways, nuclear industry equipment and the like, which have high requirements of corrosion resistance, seawater resistance and sewage resistance. A steel bar (1) with ribs on three surfaces is included, the outer surface of the steel bar (1) is coated with a layer of epoxy resin coating (2), the diameter of the steel bar (1) ranges from 4 mm to 12 mm, and the steel bar (1) has three surface crescent diagonal ribs on the surface of the steel bar in the length direction. Through coating the outer surface of the steel bar, the utility model greatly improves corrosion resistance, seawater resistance and sewage resistance of the steel bar, so that the steel bar can be applied to fields of cross-sea bridges, high-speed railways, nuclear industry equipment and the like, which have high requirements of corrosion resistance, seawater resistance and sewage resistance.
Description
(1) technical field
The utility model relates to a kind of building iron.Be applied to the fields such as bridge spanning the sea, high-speed railway and nuclear industrial facility that corrosion resistance, sea water resistance and resistant water-based etc. are had relatively high expectations.Belong to reinforced concrete structure structural steel technical field.
(2) background technology
By international saying, building iron is divided into three major types: i.e. plain steel-bar, Ribbed Bar and epoxy plain steel-bar welded mesh.Ribbed Bar is to be mother metal with ordinary carbon steel or low-alloy steel hot rolling wire rod, has reinforcing bars two-sided or three crescent diagonal ribs on its surface along the formation of reinforcing bar length direction through limit rolled edge annealing back.Ribbed Bar and concrete adhesion strength are equivalent to more than 3 times of plain steel-bar.But poor-performings such as Ribbed Bar is corrosion-resistant, sea water resistance and resistant water.The muscle of being advocated, stirrup and the distributing bar that can only be used for the cast-in-place concrete structure part, and the steel bar stress in the medium and small prestressed concrete member.And can not be applied to the fields such as bridge spanning the sea, high-speed railway and nuclear industrial facility that corrosion resistance, sea water resistance and resistant water-based etc. are had relatively high expectations.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of corrosion resistance, sea water resistance and resistant water-based are provided, and good epoxy three is worn the rib steel muscle.
The purpose of this utility model is achieved in that a kind of epoxy three wears the rib steel muscle, comprise that three wear the rib steel muscle, be characterized in: be coated with one deck epoxy coating at described three external surfaces of wearing the rib steel muscle, described three to wear the rib steel muscle be to have three crescent diagonal ribs on the surface of described reinforcing bar along this reinforcing bar length direction.
The beneficial effects of the utility model are:
The utility model is by all applying one deck epoxy resin at three external surfaces of wearing the rib steel muscle, improved three greatly and worn corrosion resistance, sea water resistance and the resistant water-based energy of rib steel muscle, so can be applied to the fields such as bridge spanning the sea, high-speed railway and nuclear industrial facility that corrosion resistance, sea water resistance and resistant water-based etc. are had relatively high expectations.

Fig. 1 wears the stereoscopic figure of rib steel muscle for the utility model epoxy three.
Fig. 2 is the vertical view of Fig. 1.
Reference numeral among the figure:
Three wear rib steel muscle 1, epoxy coating 2.
(5) specific embodiment
Referring to Fig. 1 and Fig. 2, Fig. 1 wears the stereoscopic figure of rib steel muscle for the utility model epoxy three.Fig. 2 is the vertical view of Fig. 1.As seen from Figure 1, the utility model epoxy three is worn the rib steel muscle, be to apply one deck epoxy coating 2 and form at three external surfaces of wearing rib steel muscle 1, described three to wear rib steel muscle 1 be to have three crescent diagonal ribs on the surface of described reinforcing bar along this reinforcing bar length direction.Its diameter is 4mm～12mm, and intensity is respectively 500N/mm
2, 650N/mm
2And 800N/mm
2Three Estate.
Claims (1)
1. an epoxy three is worn the rib steel muscle, comprise that three wear rib steel muscle (1), it is characterized in that: be coated with one deck epoxy coating (2) at described three external surfaces of wearing rib steel muscle (1), the diameter that described epoxy three is worn the rib steel muscle is 4mm～12mm, and described three to wear rib steel muscle (1) be to have three crescent diagonal ribs on the surface of described reinforcing bar along this reinforcing bar length direction.
