Abstract
The present invention relates to a kind of building bar of three-pointed hollow star.A kind of building bar of three-pointed hollow star, it is characterised in that reinforcing bar body (1) is that hollow bore (2) is provided with the strip that cross section is triangle, reinforcing bar body (1).The present invention is that triangular reinforced bar makes reinforcing bar accumulate maximum with concrete surface with section, and connection is more preferable, while using hollow design, reaching identical stress effect, can save 1/4 steel.
Description
Technical field
The present invention relates to a kind of building bar of three-pointed hollow star.
Background technology
At present, developing rapidly with China's economy, every profession and trade constantly increases the demand of steel, and building trade is used
Steel proportion is especially prominent, therefore during architecture production, the saving steel that should be tried one's best reduces the waste of steel.
China's steel and iron industry has come into the developing stage served as theme with structural adjustment.With China's process of industrialization
Accelerate, the upgrading of metallurgical industry product is greatly facilitated in the construction quality level requirement more and more higher of infrastructure construction.
The spiral being especially widely used at present in building field, can not meet the quality requirement of skyscraper.
The need for meeting construction market, in order to prevent later heavy construction, building to be broken the recurrence of collapse accident,
It is very necessary from the building spiral with more high-yield strength.China is earthquake and natural calamity hotspot,
Once generation ruinous earthquake and natural calamity, the damaged influence on building are quite serious.In order to shockproof, vigorously advocate in weight
The reinforcing bar of high intensity, shock resistance and solderability is used in point engineering and skyscraper.It is generally now that section is circular length with reinforcing bar
Bar shaped, their insufficient strength is high, directly affects the construction cost and security of building structure.
The content of the invention
The problem to be solved in the present invention is that there is provided one kind is hollow in order to make up the not high enough deficiency of existing reinforced steel bar strength
The building bar of triangle.
A kind of building bar of three-pointed hollow star of the present invention, it is characterised in that reinforcing bar body (1) is that cross section is triangle
Hollow bore (2) is provided with the strip of shape, reinforcing bar body (1).
A kind of building bar of three-pointed hollow star of the present invention, it is characterised in that the section of described reinforcing bar body (1) is
Three is just angular.
A kind of building bar of three-pointed hollow star of the present invention, it is characterised in that hollow in described reinforcing bar body (1)
Hole (2) is the cavity that section is triangle.
A kind of building bar of three-pointed hollow star of the present invention, it is characterised in that hollow in described reinforcing bar body (1)
Hole (2) is that section is circular cavity.
A kind of building bar of three-pointed hollow star of the present invention, it is characterised in that hollow in described reinforcing bar body (1)
Hole (2) sectional area is the 1/2-2/3 of its sectional area.
A kind of building bar of three-pointed hollow star of the present invention, is to use hollow gores shape reinforcing bar, actual to answer
Certain area obtains maximum perimeter and has been finalized in, maximum with the girth of equilateral triangle, and section for building is triangular reinforced bar
Reinforcing bar is set to accumulate maximum with concrete surface, connection is more preferable, and the equilateral triangle of area equation is 1.327966 times of circular area,
1.7706214 times of shear(ing) area, so having more preferable combination with concrete using section for the reinforcing bar of triangle, and bear root
Big shearing.Hollow design is used simultaneously, identical stress effect is reached, 1/4 steel can be saved.
