Abstract
The utility model relates to screw steel bars with elliptic cross sections, which make longitudinal bars and transverse bars broadened through adopting that the main cross sections of the steel bars are in the ellipse shape. The structure can make the surfaces of the steel bars enlarged; the cooling effect is improved in the rolling process, and accordingly, the tensile strength is increased. Simultaneously, the gripping force with the cement can be enlarged; the cross section coefficient can be enlarged in the long shaft direction; the anti-bend ability can be improved, and the using field of the steel bars can be enlarged.
Description
The utility model relates to a kind of construction material, particularly a kind of oval cross section screw-thread steel.
Spiral for building at home and abroad main cross section is circular at present, is furnished with various vertical muscle and horizontal bar on it, and size is the yarn rowization.They bear pulling force or pressure in armored concrete spare.Technical performance index is standardization such as tension, they all with steel billet by roll repeatedly hot-rolled and cold-rolled (draw, dial) make shape.
The purpose of this utility model provides a kind of spiral of oval cross section.
The utility model is to adopt such method to realize: the spiral of oval cross section is to adopt the main cross section of reinforcing bar for oval, and has widened vertical muscle and horizontal bar, size yarn rowization, to name its specification with cross section round bar diameter so that relatively use.
Ellipse is compared with the long-pending circle of uiform section, and its girth increases, and long axis direction upper section yarn number increases, and size reduces on the short-axis direction.
The utlity model has rebar surface and increase, the cold-working effect in the operation of rolling improves, thereby has improved tensile strength.Bond stress with cement increases simultaneously, and long axis direction cross section yarn number increases, and bending resistance improves, and has enlarged reinforcing bar and has used the field.Elliptical shape is easier to the design of rolling hole shape, has improved the roll radius of clean-up theoretically, has increased rolling power.The short-axis direction size reduces, and makes roll hole shape cutting output reduce, and the corresponding reduction of roller consumption rate has reduced cost.Oval in addition screw-thread steel makes that the pass process tool is simple, and the life-span is long.
Concrete structure of the present utility model and embodiment are provided by the following drawings.
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 is a side structure schematic diagram of the present utility model.
Fig. 3 is a cross-sectional view of the present utility model.
Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.
See shown in Fig. 1-3: the spiral of oval cross section is to adopt the main cross section of reinforcing bar to be oval (1), and has widened vertical muscle (2) and horizontal bar (3), size yarn rowization, to name its specification with cross section round bar diameter so that relatively use.
Ellipse is compared with the long-pending circle of uiform section, and its girth increases, and long axis direction upper section yarn number increases, and size reduces on the short-axis direction.
The utlity model has rebar surface and increase, the cold-working effect in the operation of rolling improves, thereby has improved tensile strength.Bond stress with cement increases simultaneously, and long axis direction cross section yarn number increases, and bending resistance improves, and has enlarged reinforcing bar and has used the field.
Claims (1)
1, a kind of spiral of oval cross section, the spiral that it has the circular section is characterized in that: the main cross section of reinforcing bar is oval (1), and has muscle of indulging (2) and horizontal bar (3).
