Abstract
The utility model discloses a rolled steel with an improved cross section, the cross section of the rolled steel takes an 'I' shape or flat round shape, the ratio between the short diameter and the long diameter of the cross section is 1:1.4-2.4, fine striped reinforced bars 2 are additionally distributed on the side of the rolled steel, the fine striped reinforced bars are distributed in a parallel shape, the oblique angle is 30 degrees to 45 degrees, since the cross section is reduced compared with a circle, thereby, the volume of the whole rolled steel is greatly reduced, the steel resources are saved to the maximum, and furthermore the fine striped reinforced bars are arranged on the side of the rolled steel to guarantee the rigidness of the reinforced bars.
Description
Technical field
The utility model relates to a kind of steel for building, relates to the steel that a kind of pair cross-section that can be used in the concrete structure member carries out improved specifically.
Background technique
Reinforced concrete has obtained using extremely widely at present, is all to be unable to do without the member that concrete combines with reinforcing bar in bridge works, construction of hydropower facilities, building construction and underground traffic.But the demand of steel constantly increases, and iron and steel resource belongs to non-renewable resources, minimizing day by day, thereby the also progressively raising of the price of steel, and can replace the material of steel effect also to fail at present to find fully.Therefore, can save steel in same engineering, be a good job of benefiting the nation and the people really.Just because of this, the technician racks one's brains and wishes can be technically make improvements existing steel.
Summary of the invention
The purpose of this utility model is all to be circular defective at existing reinforcing bar, and a kind of improved steel in a kind of cross section that improved cross section, novel structure are provided.This steel can have good binding ability equally in concrete.The utility model is realized by following technological scheme.
The improved steel in a kind of cross section, steel cross section are " worker " font or oblateness, and described cross section minor axis and slenderness ratio are 1: 1.4-2.4; Side at steel also is distributed with slice reinforcing bar 2, and the slice reinforcing bar is parellel and distributes, and its oblique angle is 30 °-45 °.
Compared with prior art, the beneficial effects of the utility model are: because the section ratio circle reduces, thereby the volume of whole steel reduces greatly, saves steel resources to greatest extent; In addition, the steel side is provided with the slice reinforcing bar and can keeps reinforcing bar hardness.
Description of drawings
Fig. 1 is the utility model " worker " shaped sections schematic representation;
Fig. 2 is the oblate schematic cross-section of the utility model;
Fig. 3 is the utility model side schematic view.
Among the figure, 1 is the cross section of steel, and 2 is the slice reinforcing bar of steel side.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
In Fig. 1 and Fig. 2, can see that steel cross section 1 is " worker " font or oblateness, described cross section minor axis and slenderness ratio are 1: 1.4-2.4; Side at steel also is distributed with slice reinforcing bar 2, and slice reinforcing bar 2 is parellel and distributes, and its oblique angle is 30 °-45 °.
Owing to be distributed with the upper and lower part of not having several slice reinforcing bars 2 pulling steel in two sides of reinforcing bar, make the hardness of steel increase greatly.Therefore, the steel that the utility model is made had both kept the hardness of original steel, had saved material again.
Claims (2)
1, the improved steel in a kind of cross section is characterized in that: the steel cross section is " worker " font or oblateness, and described cross section minor axis and slenderness ratio are 1: 1.4-2.4.
2, the improved steel in cross section according to claim 1 is characterized in that: be distributed with the slice reinforcing bar in the side of steel, the slice reinforcing bar is parellel and distributes, and its oblique angle is 30 °-45 °.
