The utility model discloses a reinforcing bar base circle, cross rib, size, installation angle and the installation distance's of rib settlement from north to south to the higher novel hot rolling ribbed steel bar of intensity has been obtained.
Description
Technical field
This utility model relates to bar material field, is specifically related to a kind of hot rolled ribbed bars.
Background technology
Iron and steel is the basis of national economic development, plays vital effect in economic construction.Especially since in recent years, along with improving constantly of living standards of the people, and the urgent needs of construction well-off society, the progressively increasing of domestic capital construction paces, demand as the Ribbed Bar of building trade main material is continuously increased, and the kind of reinforcing bar, specification are also corresponding constantly to be expanded.In recent years, along with the high-strength Ribbed Bar success development and production of 50mm, providing materials for support for large quantities of putting into operation of key state project project, strengthening infrastructure further for country from now on provides product guarantee.Along with the progressively expansion of bar gauge, the development of 60mm hot rolled ribbed bars is imperative.60mm Ribbed Bar belongs to the super large-scale in domestic and international Ribbed Bar, and this specification reinforcing bar now has no production both at home and abroad.But it practice, deepening continuously along with nation-building, in the design, the reinforcing bar of tradition specification increasingly can not meet Reinforced Concrete Design requirement to some superhuge foundation engineerings, and the production of 60mm Ribbed Bar, design, research and development are put on agenda.60mm Ribbed Bar is widely used in the national ultra-large engineering constructions such as the basis of the large-scale bridges and culverts in key state project, tunnel, coast defence, skyscraper, it is possible to resolve the subject matter existed in design, construction.
The production of 60mm Ribbed Bar belongs to particular/special requirement reinforcing bar, it it is one of the developing direction of building bar from now on, this super large-scale reinforcing bar combines with steel grade characteristic specific use steel such as can producing super large-scale corrosion resisting steel, anti-seismic steel bar, solving the needs about particular band rib reinforcement in the development of the national economy, its social benefit is notable.But it is owing to this reinforcing bar is as the limit material in producing, not yet widely used at home at present.
In GB1499, the bar gauge of regulation is the specification that 6-50mm, 60mm hot rolled ribbed bars belongs to beyond standard, and its configuration design is the key link of research and development of products.This utility model patented technology is exactly start with from basic demands such as the production of reinforcing bar, uses, redesigns the hot rolled ribbed bars producing 60mm specification.
Utility model content
For solving the problems referred to above, this utility model provides a kind of hot rolled ribbed bars.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of hot rolled ribbed bars, including reinforcing bar basic circle, cross rib, longitudinal rib, it is 58.2 ± 0.9mm that reinforcing bar basic circle is provided with some cross ribs and longitudinal rib, the size of reinforcing bar basic circle and tolerance；Angle α=67.5 °, surface of cross rib surface and reinforcing bar basic circle；The top width b=3mm of cross rib；The height h of cross rib is 3.5 ± 1.3mm；The nominal spacing L of cross rib is 17 ± 1.3mm；Gap between the end of the cross rib in reinforcing bar basic circle two adjacent surfaces is 16mm；The angle β of the axis of cross rib and reinforcing bar basic circle is 45 °；The top width a of longitudinal rib is 4.8mm；The height h1 of longitudinal rib ranges for: 1.0≤h1≤4.0mm.
This utility model has the advantages that
By the setting of reinforcing bar basic circle, cross rib, the size of longitudinal rib, setting angle and mounting distance, thus obtaining the Novel hot-rolled Ribbed Bar that intensity is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model structural representation.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As it is shown in figure 1, this utility model embodiment provides a kind of hot rolled ribbed bars, including reinforcing bar basic circle 1, cross rib 2, longitudinal rib 3, it is 58.2 ± 0.9mm that reinforcing bar basic circle 1 is provided with some cross ribs 2 and longitudinal rib 3, the size of reinforcing bar basic circle 1 and tolerance；Angle α=67.5 °, surface of cross rib 2 surface and reinforcing bar basic circle 1；The top width b=3mm of cross rib 2；The height h of cross rib 2 is 3.5 ± 1.3mm；The nominal spacing L of cross rib 2 is 17 ± 1.3mm；Gap between the end of the cross rib 2 in reinforcing bar basic circle 1 two adjacent surfaces is 16mm；The angle β of the axis of cross rib 2 and reinforcing bar basic circle 1 is 45 °；The top width a of longitudinal rib 3 is 4.8mm；The height h1 of longitudinal rib 3 ranges for: 1.0≤h1≤4.0mm.
Originally the setting by reinforcing bar basic circle, cross rib, the size of longitudinal rib, setting angle and mounting distance it is embodied as, thus obtaining the Novel hot-rolled Ribbed Bar that intensity is higher.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
