Abstract
The utility model provides a corrugated web, which belongs to construction steel. The corrugated web is characterized in that the cross section of the corrugated web is a sinusoidal curve or a trapezoidal curve. The cross section of the corrugated web is the sinusoidal curve or the trapezoidal curve, so that the share of normal force and shearing force on the section of the corrugated web is clear, under the axial force action on the section, only the edge of the web is subjected to acting force and under the shearing force action, only the web is subjected to the acting force, so that yield strength of part of the web is increased and out-plane stiffness is high. Regular thin flat steel plates are processed to form both the corrugated web and a trapezoidal web through a sheet-forming machine, so that processes of forming and processing are simple, steel sources are saved and production cost is reduced.
Description
Technical field
The utility model relates to a kind of structural steel, especially relates to a kind of wave web and trapezoidal web.
Background technology
H shaped steel is because cross section economical rationality, superior performance, processing and fabricating and installation technology are simple, convenient, fast; Become material components important in the construction steel structure system, thereby be widely used in the every field of the development of the national economy, industrial premises; The tower body equipment supporter; The steel smelting platform of metallurgy industry, high furnace frame, track etc., the coal bunker of power plant, conveying gallery etc.; Large-scale constructions such as land and offshore oil drilling platform, vehicle, warehouse style large supermarket, bridge tunnel all have been applied to the H shaped steel of all size, size.
At present generally use web, be generally flat web in the structural steel field.Because the depth of section of this flat web is bigger, when less shear stress or normal stress, the local buckling or the distortion of web appear easily.In order to prolong the application life of web, mainly be to adopt the raising web thickness perhaps to be provided with vertically or horizontal reinforcement gusset in the web both sides.Operation is not only wasted time and energy like this, but also the waste resource increases cost of production.The problem that existing web exists is: application life is shorter, and the waste resource increases cost of production.
Summary of the invention
The purpose of the utility model is exactly not enough to existing in prior technology, and a kind of technical scheme of novel web is provided.It is shorter that this programme can effectively solve the application life of existing web existence, and the waste resource increases the cost of production problem.
This programme is realized through following technique measures: the corrugated web of the utility model, its special feature is: the cross section of described corrugated web is a curve.
In order further to improve the present technique scheme, the special feature of the utility model corrugated web also is: the cross-section curve of described corrugated web is a sine curve.
In order further to improve the present technique scheme, the special feature of the utility model corrugated web also is: the cross-section curve of described corrugated web is a step curve.
In order further to improve the present technique scheme, the special feature of the utility model corrugated web also is: described corrugated web forms pressing via the pressure roller of regular Boping steel plate through a pair of continuous rotation.
In order further to improve the present technique scheme, the special feature of the utility model corrugated web also is: described corrugated web has four edges, described four edge parallelograms or trapezoidal.
In order further to improve the present technique scheme, the special feature of the utility model corrugated web also is: four edge institute parallelograms of said corrugated web are rectangle.
In order further to improve the present technique scheme, the special feature of the utility model corrugated web also is: four edges of described corrugated web are the trapezoidal right-angled trapezium that is.
The beneficial effect of this programme can be learnt according to the narration to such scheme; Because the corrugated web cross-section curve of this programme is sine curve or step curve; Axle power and shearing are shared comparatively clear and definite on the corrugated web cross section: the cross section is under the effect of axle power; Only there is web edge to receive active force, under shearing action, only has web to receive active force; Make web local yielding intensity increase like this, the outer rigidity of face is bigger.Because corrugated web all processes through sheet-forming machine by regular Boping steel plate, thereby have moulding and process is easy, practice thrift steel resources, reduce advantages such as cost of production.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of corrugated web.
Fig. 2 is another structural representation of Fig. 1.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below through a specific embodiment, and combine its accompanying drawing, this programme is set forth.
Can find out through accompanying drawing 1-2, the corrugated web of the utility model, its special feature is: the cross section of described corrugated web is sine curve or step curve.
The process of the corrugated web of the utility model is very simple and convenient: processing this wave web or trapezoidal web needs sheet-forming machine; Sheet-forming machine is made up of importation, moulding section and output; The importation can be imported flat sheet to moulding section; Sheet material can adopt manual input, also available conveyer belt automatic transport.Earlier regular Boping steel plate is placed into the importation of sheet-forming machine, the moulding section of sheet-forming machine is mainly bottom roll, topping roll, thickness of slab adjusting device and carry-over pinch rolls group.Topping roll and bottom roll parallel axes, to rolling, rotating speed is identical in opposite directions, and sheet material enters between topping roll and the bottom roll through the carry-over pinch rolls group, after occuring bending and deformation under the pressure effect of topping roll and bottom roll, has formed wave web or trapezoidal web.When the sheet metal thickness of processing changes, to regulate the thickness of slab adjusting device, and then changed the gap length between topping roll and the bottom roll, the corrugated web after the processing is exported by output, gets into the finished product district.This web processing is simple, and high efficiency is fit to processing in enormous quantities.
