Abstract
The invention discloses a four-side ribbed bar comprising a ribbed bar body. The length direction of the ribbed bar body is provided with four-side diagonal ribs which are arranged on the surface of the ribbed bar body in a crescent shape and in a projecting mode and are evenly distributed on the excircle of the ribbed bar body; adjacent two-side diagonal ribs have reverse inclining direction; the diagonal rib on each side is composed of a plurality of small crescent diagonal ribs; and the small crescent diagonal ribs are evenly distributed at interval along the length direction of the ribbed bar body. The invention has the beneficial effects that the four-side ribbed bar overcomes the technical defect of the prior art. The four-side ribbed bar has reliable anchoring for sticking with concrete if compared with the traditional three-face ribbed bar, and cohesive strength is more than one time of that of the three-side ribbed bar and is more than two times of that of two-face ribbed bar. The four-side ribbed bar has good integrity after bonded with concrete and improves cracking ability by above 25% if compared with the three-side ribbed bar.
Description
Technical field
The present invention relates to build Ribbed Bar, particularly be the four sides Ribbed Bar.
Background technology
Before the present invention makes, be used for the muscle of being advocated, stirrup and the distributing bar of cast-in-place concrete structure part, and the reinforcing bar of the aspect such as stressed in the medium and small prestressed concrete member mostly adopts plain steel-bar, two sides rib steel muscle, three rib steel muscle in the past.Plain steel-bar and concrete binding anchoring are unreliable, and adhesion strength is low, and globality is relatively poor, deviation is big, cracking resistance is relatively poor.Two sides rib steel muscle, three rib steel muscle and concrete binding are strong slightly.People wish to occur and the more desirable four sides Ribbed Bar of concrete binding anchoring meeting.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and concrete binding anchoring reliable, adhesion strength height, and good integrity, deviation is little, cracking resistance is good four sides Ribbed Bar.
The technical scheme that solves the problems of the technologies described above is: a kind of four sides Ribbed Bar, described four sides Ribbed Bar comprises the reinforcing bar body, have the four sides diagonal rib in described reinforcing bar body length direction, described four sides diagonal rib is meniscate protrusion and is arranged at the reinforcing bar body surface and is distributed on the cylindrical of reinforcing bar body; The incline direction of adjacent two diagonal ribs is opposite; Be made up of the little diagonal rib of a plurality of crescent on the diagonal rib of each face, the little diagonal rib of described crescent is along the even distribution at interval of reinforcing bar body length direction.
The invention has the beneficial effects as follows: the present invention four sides Ribbed Bar overcomes the prior art defective, anchoring is reliable more than three rib steel muscle of tradition with concrete bonding for the four sides Ribbed Bar, adhesion strength is equivalent to three and wears more than 1 times of rib steel muscle, is equivalent to two and wears more than 2 times of rib steel muscle; The four sides Ribbed Bar combines the back good integrity with concrete, cracking resistance is worn the rib steel muscle than three and improved more than 25%.

The specific embodiment
Fig. 1 is the front view of the present invention four sides Ribbed Bar; Fig. 2 is the left view of Fig. 1.
As shown in the figure, the invention provides a kind of four sides Ribbed Bar, described four sides Ribbed Bar comprises reinforcing bar body 1, has four sides diagonal rib 2 at described reinforcing bar body 1 length direction, described four sides diagonal rib 2 is crescent, and protrusion is arranged at reinforcing bar body 1 surface and is distributed on the cylindrical of reinforcing bar body 1; The incline direction of adjacent two diagonal ribs 2 is opposite; The diagonal rib 2 of each face is made up of the little diagonal rib 2a of a plurality of crescent, and the little diagonal rib 2a of described crescent is along the even distribution at interval of reinforcing bar body 1 length direction.
Described four sides diagonal rib 2 is 45 degree with reinforcing bar body 1 shaft angle β.
Described four sides diagonal rib 2 protrudes the high h of diagonal rib mid point that is arranged at reinforcing bar body 1 surface: 0.30-0.95mm.
Spacing b between adjacent two diagonal ribs 2 is not less than: 0.027-0.042mm.
The top width δ of the little diagonal rib 2a of described crescent is: 0.2 times bar diameter.
Distance s is between the little diagonal rib 2a of adjacent crescent: 4.0-8.4mm.
