Description

Corrugated structural steel

Technical Field

The utility model relates to a building material technical field, concretely relates to corrugated structure's shaped steel.

Background

With the vigorous popularization of assembly type buildings, particularly steel structure assembly type buildings, a large amount of steel materials are inevitably used as main frame structures of the buildings, wherein I-shaped steel and H-shaped steel are named due to the fact that the cross sections of the I-shaped steel and the H-shaped steel are I-shaped, the I-shaped steel and the H-shaped steel are usually used as steel beams through welding or bolt connection, the strength requirement of the I-shaped steel and the H-shaped steel is high when the I-shaped steel and the H-shaped steel are used as the steel beams, the existing means for increasing the strength of the I-shaped steel and the H-shaped steel are limited and are usually realized through increasing the thickness of the I-shaped steel and the H-shaped steel, the mode wastes the steel materials, and the operation is inconvenient, time-consuming and labor-consuming due to the increase of the steel material quantity and the weight. Therefore, a steel material having excellent properties, high strength and light weight has been required to be studied.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model provides a corrugated structure's shaped steel to improve the intensity of I-steel and H shaped steel, practice thrift the steel consumption of I-steel and H shaped steel, intensity of labour when reducing the assembly.

In order to achieve the above object, the utility model provides a corrugated structure's shaped steel, including I-steel body and H shaped steel, I-steel and H shaped steel body have a plurality of circular, oval or square ripple grooves or ripple arch on the extending direction of its flange board and web, and the ripple groove corresponds each other with the ripple arch and forms corrugated structure, each ripple groove and each the protruding one-to-one of ripple.

The overall strength of the I-shaped steel and the H-shaped steel is improved through the corrugated mechanism, the steel increment of the corrugated structure is far smaller than that of the common I-shaped steel through the same strength design, the strength is improved, the consumption of steel resources is saved, the overall weight is reduced, and the transportation and the assembly are convenient.

Furthermore, a plurality of corrugated grooves in the I-shaped steel and H-shaped steel bodies are located on the same plane, a plurality of corresponding corrugated bulges are located on the other plane, and the corrugated structures of the top surface parts of the I-shaped steel and H-shaped steel bodies and the bottom surface parts of the I-shaped steel bodies are in one-to-one symmetry, so that when a bridging piece or other workpieces are required to be connected through the I-shaped steel and H-shaped steel, the connection can be realized more easily and more conveniently when the I-shaped steel and H-shaped steel are required to be connected.

The beneficial effects of the utility model embody: the utility model discloses structurally through original I-steel again, set up a plurality of ripple column structure along I-steel and H shaped steel extending direction for this I-steel and H shaped steel's bulk strength improves, and the shear resistance improves, and whole quality change is little, has practiced thrift steel, has reduced use cost, and the ripple groove all sets up the one side subsequent joint of being convenient for with the ripple arch and inserts, has improved its suitability.
