Abstract
The invention discloses a double-wing I steel for a bridge girder. The double-wing I steel comprises a first cross rod; the cross rod is connected with two vertical rods placed vertically side by side; two second cross rods placed transversely side by side are connected between the vertical rods; and the other ends of the vertical rods are connected with the same third cross rods. Compared with a common I steel, the double-wing I steel has the advantages of stronger bearing capacity, simpler structure, lower cost and the like.
Description
Technical field
The present invention relates to a kind of i iron, refer in particular to a kind of double-vane i iron, be used for bridge main beam.
Background technology
Bridge is as the important component part of highway engineering, the integrality of its structure structure will directly have influence on the safety and the comfortableness of highway communication transportation, and i iron is done to play an important role in the bridge main beam structure, and the strength that general i iron does not have the i iron of double airfoil type to bear is strong.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, a kind of simple in structure, a kind of bridge main beam-double-vane i iron that cost is low is provided.
Purpose of the present invention is achieved through the following technical solutions: a kind of bridge main beam-double-vane i iron, comprise first cross bar, described cross bar is connected with two vertical montants placed side by side, be connected with two second cross bars of laterally laterally placing side by side between the every described montant, the every described montant other end is connected with same the 3rd cross bar.
The present invention has the following advantages: compared with general i iron, the strength that the double-vane i iron bears is stronger, and structure is very simple, and cost is also very low.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Number in the figure: 1-first cross bar, 2-montant, 3-second cross bar, 4-the 3rd cross bar.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of bridge main beam of the present invention-double-vane i iron as Fig. 1, comprise first cross bar 1, described cross bar 1 is connected with two vertical montants placed side by side 2, be connected with two second cross bars of laterally laterally placing side by side 3 between the every described montant 2, every described montant 2 other ends are connected with same the 3rd cross bar 4.Advantages such as the present invention is compared with general i iron, and the strength that the double-vane i iron bears is stronger, and structure is very simple, and cost is also very low.
