Abstract
The invention provides an I-shaped steel which is of an integral structure. The I-shaped steel comprises main supporting ribs and a supporting web; the supporting surface and the lower side surface of each main supporting rib are arc-shaped surfaces; the part in which each main supporting rib is connected with the supporting web is of an arc transition structure; a plurality of rib plates which are manufactured from fiberglass are arranged between the main supporting ribs in the supporting web direction; the rib plates are integrally fixedly connected with the main supporting ribs by welding. According to the I-shaped steel, the main body structure is the integral structure, so that the process of welding the main supporting ribs and the supporting web can be saved, the possibility of potential damage caused by welding defect can be prevented; the arc transition part in which the main supporting ribs are connected with the supporting ribs can effectively prevent the damage caused by stress concentration; in addition, the plurality of rib plates improve the overall pressure and bending resistance, and therefore, the overall strength can be greatly improved.
Description
Technical field
The present invention relates to long strands field, be specifically related to a kind of I-steel.
Background technique
I-steel also claims girder steel, be cross section is I-shaped rectangular steel, is widely used in various building structure, bridge, vehicle, support, machinery etc.Common I-steel is welded by the main muscle of upper and lower cross-brace and middle longitudinal bracing abdomen.The main muscle supporting surface of support of this I-steel is plane, therefore positive pressure is very large when bearing pressure, the main muscle of support is caused to bend, and be welded to connect owing to supporting main muscle and supporting abdomen employing, also can there is pore at weld, be mingled with, incomplete fusion, the number of drawbacks such as lack of penetration, stress is excessive, these defects cause the use of I-steel to there is potential danger.
Summary of the invention
In order to solve the technical problem existed in prior art, provide a kind of I-steel.
In order to realize this function, the present invention adopts following technological scheme:
A kind of I-steel is integral type structure, and comprise and support main muscle and support abdomen, the main muscle supporting surface of described support and downside are arc surface, and supporting main muscle and supporting abdomen joint is arc transition structure, supports between main muscle and is provided with several floors along supporting abdomen direction.
Further, described floor uses glass fibre reinforced plastics to make.
Further, described floor is fixed together by welding with supporting between main muscle.
Agent structure of the present invention adopts integral structure, eliminate the welding process supporting main muscle and support between abdomen, prevent the possibility of the potential damage caused due to weld defects, supporting main muscle and support the arc transition of abdomen joint can effectively prevent stress from concentrating caused stress to concentrate and the damage that causes, the design of multiple floor then enhances overall resistance to compression flex resistance, and bulk strength improves greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein:
1. support main muscle 2. and support abdomen 3. floor a. supporting surface
B. downside c. arc transition
Embodiment
Describe embodiments of the invention in detail below in conjunction with accompanying drawing, it should be noted that, the present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of I-steel, for integral type structure, comprise and support main muscle 1 and support abdomen 2, described support main muscle 1 supporting surface a and downside b is arc surface, supporting main muscle 1 and supporting abdomen 2 joint is arc transition c structure, support between main muscle 1 and be provided with several floors 3 along supporting abdomen 2 direction, floor 3 uses glass fibre reinforced plastics to make, and described floor 3 is fixed together by welding with supporting between main muscle 1.
Agent structure of the present invention adopts integral structure, eliminate the welding process supporting main muscle 1 and support between abdomen 2, prevent the possibility of the potential damage caused due to weld defects, the damage that the arc transition c supporting main muscle 1 and support abdomen 2 joint effectively can prevent stress from concentrating caused stress to concentrate and cause, the design of multiple floor 3 then enhances overall resistance to compression flex resistance, and bulk strength improves greatly.
