Abstract
The invention discloses high-intensity C-shaped steel with ribs and teeth. The high-intensity C-shaped steel with ribs and teeth comprises a body 1, wherein an inner test notch of the body 1 is provided with positioning teeth 2; the shapes of the positioning teeth 2 are equilateral triangles; the included angle alpha among the positioning teeth 2 is 60 degrees; the side surface of the body 1 is provided with reinforcing ribs 3 which are formed by combining reinforced bar steel and high-carbon steel, are at least two or multiple, are horizontally distributed, and are in convexity. The high-intensity C-shaped steel with ribs and teeth can fix connecting elements rapidly and safely by utilizing the structures of the positioning teeth; the positioning teeth are equilateral triangles; the included angles alpha among teeth are 60 degrees; the triangles are stable in structure, and the stability of the equilateral triangles achieves the maximal value through calculation; the combined structure of reinforced bar steel and high-carbon steel is adopted for the reinforcing ribs, the intensity is intensified greatly, and the bearing capability is improved through the reinforcing effect of the multiple reinforcing ribs at the lateral side.
Description
Technical field
The present invention relates to C shaped steel, particularly a kind of high strength band muscle band tooth C shaped steel.
Background technology
C shaped steel processes through the clod wash of hot rolling plate, and wall is thin from heavy and light, the cross section function admirable, and intensity is high.Employed traditional C shaped steel on present most of market, in making installation process, have following problem: the designer is when selection, in order to consider the supporting capacity of C shaped steel, when selecting traditional C shaped steel, often type selecting is bigger than normal, has both greatly increased so virtually building costs, has wasted material resources on the very large aspect again.And when cooperating with connector, run into outer effect, and lack fixation kit, easily produce loosening and displacement, hide some dangers for so just for construction quality and safety.In the patent No. is 201020214526.7 patent of invention, C shaped steel has adopted the sawtooth of isosceles right triangle to fix, and the concave surface reinforcing rib is set in the side, but in actual use, isosceles right triangle structure sawtooth bearing capacity is not enough, is difficult to long-time fixed connecting piece.And in the actual mechanical process, side concave surface enhancing muscle is difficult to stressed, requires further improvement.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, a kind of high strength band muscle band tooth C shaped steel is provided, it has very high intensity, adds large bearing capacity, economical with materials; And can be good at fixed connecting piece, easy construction safety.
Purpose of the present invention realizes like this:
A kind of high strength band of the present invention muscle band tooth C shaped steel comprises body, wherein, surveys notch in the described body and is provided with positioning tooth, during use, can make connector firmly fixing.
Above-mentioned a kind of high strength band muscle band tooth C shaped steel, wherein, described positioning tooth is shaped as equilateral triangle.
Above-mentioned a kind of high strength band muscle band tooth C shaped steel, wherein, being angle α between described positioning tooth is 60 °.
Above-mentioned a kind of high strength band muscle band tooth C shaped steel, wherein, described body side is provided with reinforcing rib, and described reinforcing rib is by concrete-steel and high-carbon steel is compound consists of.
Above-mentioned a kind of high strength band muscle band tooth C shaped steel, wherein, described reinforcing rib has 2 or many at least, and is cross direction profiles, is convex-surface type.
Compared with prior art, the present invention has the following advantages:
1) intensity is large, and this kind steel concentrated load of beam length 300m reaches as high as 1497.27.
2) needn't select relatively large number steel, reduce the steel use amount, reduce building costs.
3) positioning tooth fixed connecting piece firmly improves construction quality, guarantees construction safety.
4) reinforcing rib adopts by concrete-steel and high-carbon steel composite construction, greatly gains in strength.
5) can realize Fast Installation by positioning tooth, easy to use, the dismounting that is easy to construct and replacing.
A kind of high strength band of the present invention muscle band tooth C shaped steel utilizes the positioning tooth structure, can fast and safely connector be fixed; Positioning tooth is equilateral triangle, and angle α is 60 o between tooth and the tooth, and triangular structure is stable, and the stability of equilateral triangle reaches maximum value as calculated; Reinforcing rib adopts by concrete-steel and high-carbon steel composite construction, greatly gains in strength, and by many booster actions that strengthen muscle of side, reaches and improved supporting capacity.
Description of drawings
Fig. 1 is structure chart of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
A kind of high strength band of the present invention muscle band tooth C shaped steel comprises body 1, and wherein, described body 1 interior survey notch is provided with positioning tooth 2, during use, can make connector firmly fixing; Described positioning tooth 2 is shaped as equilateral triangle; It is 60 ° that 2 institutes of described positioning tooth are angle α; Described body 1 side is provided with reinforcing rib 3, and described reinforcing rib 3 is by concrete-steel and high-carbon steel is compound consists of; Described reinforcing rib 3 has 2 or many at least, and is cross direction profiles, is convex-surface type.
In sum, a kind of high strength band of the present invention muscle band tooth C shaped steel utilizes positioning tooth 2 structures, can fast and safely connector be fixed; Positioning tooth 2 is equilateral triangle, and angle α is 60 o between tooth and the tooth, and triangular structure is stable, and the stability of equilateral triangle reaches maximum value as calculated; Reinforcing rib adopts by concrete-steel and high-carbon steel composite construction, greatly gains in strength, and by many booster actions that strengthen muscle of side, reaches and improved supporting capacity.
Advantage of the present invention: 1, intensity is large, and this kind steel concentrated load of beam length 300m reaches as high as 1497.27.2, needn't select relatively large number steel, reduce the steel use amount, reduce building costs.3, positioning tooth fixed connecting piece firmly improves construction quality, guarantees construction safety.4, reinforcing rib adopts by concrete-steel and high-carbon steel composite construction, greatly gains in strength.5, positioning tooth can be realized Fast Installation, and is easy to use, the dismounting that is easy to construct and replacing.
Performance data such as the following table of the prepared high strength band of the present invention muscle band tooth C shaped steel:
