Abstract
The invention discloses a novel formula of a semi-grouting type high-strength thick reinforcing bar. The semi-grouting type high-strength thick reinforcing bar comprises the following trace elements in parts by weight: 0.18-0.29 part of C, 0.20-0.80 part of Si, 1.50-2.10 parts of Mn, 0.04-0.12 part of V, 0 part of Ti, less than or equal to 0.025 part of P and less than or equal to 0.025 part of S. The novel formula of the semi-grouting type high-strength thick reinforcing bar disclosed by the invention can be used for overcoming the defects in the prior art of unreasonable proportion, complex machining process, poor stability and the like so as to achieve the advantages of reasonable proportion, simple machining process and good stability.
Description
Technical field
The present invention relates to steel bar meter technical field, particularly, relate to the new formula of the high-strength concrete reinforcement bar of a kind of half grouting formula.
Background technology
Mechanical connection technique of reinforcement starts till now as far back as 19 century 70s, has had all kinds of reinforced bar mechanical connectors, such as rolling straight thread connector, taper thread joint, grouting formula steel bar connector, half grouting formula steel bar connector etc.Half grouting formula steel bar connector is in these reinforcing bar connectors, and with the advantage of its uniqueness, major diameter, high-strength steel connect becomes trend of the times just gradually.
Realizing in process of the present invention, contriver finds at least to exist in prior art that proportioning is unreasonable, complete processing is complicated and the defect such as poor stability.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose the new formula of the high-strength concrete reinforcement bar of a kind of half grouting formula, to realize the advantage of the simple and good stability of reasonable ratio, complete processing.
For achieving the above object, the technical solution used in the present invention is: the new formula of the high-strength concrete reinforcement bar of a kind of half grouting formula, and in the high-strength concrete reinforcement bar of formula that should partly be in the milk, the parts by weight of each trace element are as follows:
C:0.18 ~ 0.29 part;
Si:0.20 ~ 0.80 part;
Mn:1.50 ~ 2.10 part;
V:0.04 ~ 0.12 part;
Ti:0 part;
P :≤0.025 part
S :≤0.025 part.
The new formula of the high-strength concrete reinforcement bar of half grouting formula of various embodiments of the present invention, because in the high-strength concrete reinforcement bar of this half grouting formula, the parts by weight of each trace element are as follows: C:0.18 ~ 0.29 part; Si:0.20 ~ 0.80 part; Mn:1.50 ~ 2.10 part; V:0.04 ~ 0.12 part; Ti:0 part; P :≤0.025 part S :≤0.025 part; Thus can overcome in prior art that proportioning is unreasonable, complete processing is complicated and the defect of poor stability, to realize the advantage of the simple and good stability of reasonable ratio, complete processing.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from specification sheets, or understand by implementing the present invention.
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide the new formula of the high-strength concrete reinforcement bar of a kind of half grouting formula, in the high-strength concrete reinforcement bar of formula that should partly be in the milk, the parts by weight of each trace element are as follows:
C:0.18 ~ 0.29 part;
Si:0.20 ~ 0.80 part;
Mn:1.50 ~ 2.10 part;
V:0.04 ~ 0.12 part;
Ti:0 part;
P :≤0.025 part
S :≤0.025 part.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
