Figure 11 is a partial sectional view, and it has represented how the structural steel shape that utilizes the inventive method to produce links together.
Figure 12 is the sectional drawing at 12-12 line place among Figure 11.
Figure 13 to 16 is the views that will relate to when possible further modified is described.
With reference to Fig. 1, wherein Biao Shi rolling operation is to carry out in being called the frame of universal mill.This milling train is equipped with two breaker rolls 10,10 and 12,12, and roll can be around horizontal rotational shaft to 10,10, and 12,12 can rotate around vertical axis.As shown in the figure, roll 10,10 is made into the web 14 that is used for processing finish rolling shaped steel neutral line place, the spacing of roll 12,12 and they for the installation site of roll 10,10 make the edge of a wing 16,16 of the reversed arrangement of shaped steel form with the equidistant side wing edge of arranging of the neutral line of shaped steel to 18,18.As shown in the figure, side wing edge the 18, the 18th is rolled between the side of the end of roll 10,10 and corresponding roll 12,12.
As can be seen, the finish rolling section bar is a kind of section bar of more complicated, generally adopts pressing method to make of aluminium.But,, certainly produce this section bar with ferrous metal even with stainless steel if adopt the rolling operation.When making as structural steel, this shaped steel is with particularly useful, because the groove 20 between the side wing edge of being separated by is to 18,18 can be used for holding the edge of glass and wallboard.
Represented further processing possible in the inventive method among Fig. 2.Promptly rolled section steel is bent to the represented shape of solid line.If the web of shaped steel is thicker, this further processing will be carried out when rolled section steel is still heat certainly; But, if web is thinner, then is suitable under the state of cooling and carries out, or can carry out on the spot at the scene of using this shaped steel.After this further processing, produced the structural steel shape that is shaped as corner member, in this represented example of Fig. 2, glass or wallboard can be mutually the right angle and stretch.From illustrated example, it can also be seen that, the rolled section steel that entire body curves the right angle in shaped steel, formed one almost completely sealed hollow 22(if desired, in fact this cavity is easy to complete closed, and does not retain narrow gap as shown in the figure.The sealing of cavity can be leaned on this rolled section steel is carried out bigger bending, and a perhaps additional metal or plastic paper strip seal can certainly seal this cavity by welding).In use, can utilize this cavity in the shaped steel, for example, be used to hold electric wire.Certainly, the seam of cavity can adopt the method welding of continuous welding or interim spot welding at interval.
With reference to Fig. 3, rolled section steel needn't be symmetrical in neutral line as can be seen; In example shown in Figure 3, breaker roll 10,10 has carried out such change, and a side of the web 14 of rolled section steel and side wing edge 18 are in line.But with the same in first example, as can be seen, side wing edge 18,18 is still between the side of the end of roll 10,10 and corresponding roll 12,12 rolling.Represented possible further processing in the shaped steel shaping among Fig. 4, be still rolled section steel is bent to the shape shown in the solid line among the figure, made structural steel shape be configured as corner member.This further processing also makes and has formed a cavity 22 in the shaped steel, this shaped steel in use, cavity wherein can hold electric wire.Represented the another kind of alternative possible further processing that the rolled section steel among Fig. 3 is shaped among Fig. 5.This operation is that rolled section steel is bent to the shape shown in the solid line among the figure in the opposite direction, but, in this case, surely not central cavity has been arranged in the rolled section steel.
Represented the rolling operation of the shaped steel that the production shape is more more complicated among Fig. 6,, that is, used two breaker rolls 10,10 and 12,12 though produce the rolling operation of this shaped steel and mentioned above basic identical.But have one mainly to change herein, i.e. the profile of roll 12,12 as shown in FIG., so the edge of a wing thickness of finish rolling product does not wait.As shown in Figure 7 and Figure 8, this rolled products among Fig. 6 can then be processed to form and the similar finish rolling product of the shaped steel shown in Fig. 4 and Fig. 5, but can see, the thickness of edge of a wing part do not wait for thereon boring and tapping provide convenience with inserting bolt, screw or rod.
Certainly, can also have many other to change on basic structural steel shape, the shaped steel of these variations can be produced by rolling operation of the present invention.For example, represented a kind of rolled section steel among Fig. 9, its web 14 departs from side wing edge 18.The shaped steel of having represented a kind of further variation among Figure 10, the degree of depth of this shaped steel increases greatly, and the side wing edge of three pairs of reversed arrangement is arranged is aileron edge 18,18.The side wing edge of certain this shaped steel is to also being rolling between the respective side of the end of first breaker roll and second to (this second couple or can be a pair of more than) roll.Though do not express among the figure, but the rolled section steel of all these variations can certainly further be processed when it is still hot, its web 14 entire bodies are bent to the right angle, perhaps other needed certain angle (certainly, if the web of this shaped steel is thinner, also can when cooling off, it carry out same processing).
Represented among Figure 11 to Figure 14 Fig. 6,7 and the shaped steel depicted in figure 8 method (certainly also can build in this way to the greatest extent simple cheap housing unit) that is used to build the greenhouse.Figure 11 is the vertical cross-section that passes through a shaped steel product that is similar to Fig. 8 (just the angle of its median ventral plate entire body bending is so not big), this root shaped steel product composition the sidewall of building and the changeover portion between the roof, inclined-plane.Open web type roof spar 24 is by similar shaped steel product composition, and its abutting end is by shearing and boring-mill work.Can see that this root shaped steel product mentioned above is and another kind of shaped steel 26, and be assemblied in that small blocks 28 between these two kinds of shaped steel is used jointly, therefore, edge of a wing the widest part is in the outside as shown in the figure.One section light metal or plastic plate 30 every a segment distance by bolted this root through rolling and the shaped steel product that is shaped on, constitute one section eaves gutter.
Figure 12 is the view very similar to Figure 11, and the shaped steel that just forms changeover portion among Figure 12 between the sidewall of building and roof, inclined-plane is the product (but the angle of the web entire body bending of this rolled section steel among Figure 12 does not have among Fig. 7 big like that) that is similar among Fig. 7.Open web type spar 24 is still by similar shaped steel and constitutes, and its abutting end is by shearing and boring-mill work.Shaped steel 26 shown in the figure is laid on the concrete foundation 100, formation base shaped steel, and the top and bottom of hollow sidewall pillar 25 are by shearing and boring and milling is suitably processed.
The horizontal cross-section of the segment type product made from steel that is similar to Fig. 7 in having represented among Figure 13 to use, this shaped steel are used for constituting wall angle (different with Fig. 7 just the web deformation processing of shaped steel do not form enclosed cavity in this section product) herein.As shown in the figure, a side of wall angle-steel is equipped with the member 32 of double-deck glass, and opposite side is equipped with the member that glass is housed 34 of individual layer.The glass component of every side all is embedded in rubber or the flexible plastic gasket material 34, and tightens up with clamping bar 36, and clamping bar 36 is fixed on the appropriate location by bolt 38.Represented among the figure that plastic strip 40 edges are stuck in the appropriate location, have sealed the opening that enters cavity 22.Though (above mentioning member 32 and 34 is glass components, and the some of them member may be the common wall board member.If this building is cheap housing unit, the part in the member 32 and 34 can be a thermal insulation board at least).
Certainly, if represented building is greenhouse or greenhouse among Figure 11 to Figure 13, the glass component 32 and 34 that then constitutes sidewall should extend to the height overall of sidewall and equate.But, arranged vertical be combined in pillar between glass plate can be smaller a little.As shown in figure 14, in this case, boring at a certain distance on pillar, so that bolt 40 is penetrated in the hole of crossbeam 42 ends through boring and tapping, crossbeam 42 is made by similar shaped steel product, its end is through shearing and boring-mill work.
Adopt the shaped steel of milling method production of the present invention also can be used for being assembled into the frame structure of the building more much bigger certainly, for example build the sandwich construction of cheap housing unit than greenhouse or greenhouse.This frame structure can be built by being similar to method of attachment represented among Figure 11 to Figure 14.On the suitable height of column web, can hole, so that use bolting floor, bearing cross beam.
Certainly, adopt method of the present invention, make the shaped steel of producing by hot rolling usually further increase at least a size again, can produce other different shaped steel.For example, expressed the shaped steel of another possibility among Figure 15, it still has other a pair of main wing edge part to similar shown in Fig. 3, and shown in the cross section among Figure 15, this is to lean on the shape of top mill roll to shape to the main wing edge.Represented among Figure 16 that the shaped steel of this more complicated is used for an example of building construction.
Represented the shaped steel that another kind of available method of the present invention is produced among Figure 17 and Figure 18, the outer surface of the shaped steel shown in Figure 17 is corrugatedly (can think by the side wing edge on the main wing edge part 16,16 forming, shaped steel shown in Figure 18 has the elongated channels that has formed side wing edge at the edge along main wing edge part 16,16.But need not process the elongated channels or the edge of a wing certainly on the outer surface of major part.The roll that acts on the main wing edge outer surface partly can play the model effect to main wing edge outer surface; For example, can produce the annular knurl effect.These effects, by traditional rolling be can not be obtainable.
Can also do other various improvement, and the hot rolling structural steel shape that adopts method of the present invention to produce can there be many other purposes. In the method to above related any rolled section steel Possible further processing, namely crooked rolled section steel is produced the shaped steel that shape is corner member, can adopt variety of way to carry out, and, for the people who is familiar with this technical field, do not have any problem. For example, when shaped steel is still warm, in other mill train, carry out bending, perhaps make rolled products carry out bending by the mould that is similar to extrusion die, but processing herein only is the web of crooked shaped steel, and shaped steel is not suppressed.
