Description
Technical field
The present invention relates to a kind of cavity type light steel section bar, belong to light steel section bar equipment technical field.
Background technology
Lightweight steel construction is because from heavy and light, intensity is high, area occupied is small, and therefore, lightweight steel construction system is widely used to do
The fields such as public building, tourism building and residential housing, but existing light steel section bar is often there is the shortcomings that corrosion-resistant, from
And have influence on service life and effect.Meanwhile existing light steel section bar is generally integral slab, so as to have influence on overall deadweight,
Therefore, for loss of weight, often reduce the thickness of section bar, if go to consider from the angle of reduction section bar thickness, then
The intensity of overall section bar often cannot be guaranteed.
The content of the invention
A kind of the drawbacks of purpose of the present invention exists aiming at above-mentioned prior art, there is provided rational in infrastructure, manufacturing
Easily, the cavity type light steel section bar of section bar deadweight is mitigated on the basis of section bar thickness is not reduced.
The object of the present invention is achieved like this, a kind of cavity type light steel section bar, including steel profile, it is characterized in that：It is described
Steel profile section is square structure, and is provided with rectangular cavity in steel profile, and the outer wall of rectangular cavity is wall thickness identical steel；It is described
The first supporting steel plate, the second supporting steel plate are provided with the rectangular cavity of steel profile, the first supporting steel plate, the second supporting steel plate mutually hang down
Directly, the first supporting steel plate, the second supporting steel plate are fixedly connected with the inwall of rectangular cavity；And the outer wall and inwall of steel profile are equipped with
One layer of carbon fiber layer.
Some lightening holes are equipped with first supporting steel plate, the second supporting steel plate
The lightening hole is triangle or circular lightening hole.
The thickness of the carbon fiber layer is 0.8-1 millimeters.
The steel profile is hot-roll forming.
The inwall contact position of first supporting steel plate, the second supporting steel plate and rectangular cavity is equipped with arc reinforcer.
The corner that first supporting steel plate, the second supporting steel plate are fixed in the rectangular cavity of steel profile.
The present invention is rational in infrastructure simply, it is easy, easy to use to manufacture, and by the present invention, existing light steel section bar is entered
Row improves, and is mainly manifested in, a kind of cavity type light steel section bar, including steel profile, and steel profile section is square structure, and die
Rectangular cavity is provided with material, the outer wall of rectangular cavity is wall thickness identical steel；First is provided with the rectangular cavity of steel profile
Steel plate, the second supporting steel plate are supportted, the first supporting steel plate, the second supporting steel plate are mutually perpendicular to, the first supporting steel plate, the second supporting steel
Plate is fixedly connected with the inwall of rectangular cavity；And the outer wall and inwall of steel profile are provided with one layer of carbon fiber layer.
Steel profile surface is arranged on by such and medial surface is bonded with carbon fiber layer, therefore improves the corrosion resistant of section bar
Corrosion energy, steel profile is designed as square lumen type, alleviates section bar weight, the first supporting steel plate, are provided with rectangular cavity
Two supporting steel plates, the first supporting steel plate, the second supporting steel plate are mutually perpendicular to so that on the premise of section bar weight is mitigated so that
The intensity of section bar is strengthened so that on the basis of the intensity of section bar is not reduced, is realized that section bar weight is lighter, is effectively increased
The performance of I-shaped light steel section bar.
In the present invention, some lightening holes are provided with the first supporting steel plate, the second supporting steel plate, and lightening hole is three
Angular or circular lightening hole.Be advantageous to the lightness of steel and do not reduce the bulk strength of section bar.Meanwhile the thickness of carbon fiber layer
Spend and make it that decay resistance is most preferably played for 0.8-1 millimeters, such set.Steel profile is hot-roll forming.At first
Support steel plate, the inwall contact position of the second supporting steel plate and rectangular cavity are equipped with arc reinforcer, effectively improve the first supporting steel plate,
The intensity of the inwall contact position of second supporting steel plate and rectangular cavity.First supporting steel plate, the second supporting steel plate are fixed on steel profile
Rectangular cavity in corner, it is such set it is more reasonable so that the bulk strength of section bar is strengthened.
By the present invention, a kind of cavity type light steel section bar, have and mitigate section bar on the basis of section bar thickness is not reduced certainly
The effect of weight, there is very big market application and promotional value.
