Abstract
A structural member, such as a beam, includes a web portion (2) and flanges, where a section of the web is cut and folded outwards to reinforce the web. Preferably the folded section perpendicular to the web and forms a bracket or support for a second structural member.
Description
2364074 WEBS OF STRUCTURAL MEMBERS This invention refers to members such
as beams and columns which are for example often used in the construction industry to form the framework of a structure and are usually made of metal More particularly this invention relates to the web part of the members, this being the part that separates the flanges and usually resists predominately shear forces.
The webs of structural members often require holes to be provided in them to allow pipes, ducts, and other services to pass through within the depth of the structural member The web may require stiffening so that buckling does not take place and may often be required to provide support for incoming members Additionally the web is sometimes used to provide support for a floor In many instances the foregoing functions that the web may need to provide may require the attachment, usually by welding to the web, of separate metal items to provide stiffening or support The attachment of these separate items is time consuming and costly.
The object of this invention is to eliminate or at least reduce the need for the attachment to the web of these separate stiffening or support items.
Accordingly this invention utilises the material of the web itself to form the stiffening or support functions This is achieved by making suitable cuts in the web so that a portion of material from the web may be folded out of plane to perform the required function.
Preferably web cuts and folding would be performed by programmable devices to allow this work to be an automated procedure.
The invention may take many different forms which utilise material from the web being folded out of plane By way of illustration a limited number of examples of the invention follow:
A specific embodiment of the invention which provides the means of reinforcing a hole through the web by utilising a portion of folded web plate will now be described by way of example with reference to the drawing sheets 1/7 and 2/7 in which:
Figure 1 shows a cross-section through a structural member Figure 2 shows an elevation of a structural member indicating cut and fold lines Figure 3 shows an isometric view of the web perforation with the formed stiffening.
For identification purposes only Figure 1 shows a general cross section through a structural member, 1 being referred to as a flange and 2 being referred to as a web The profile of a structural member could take many other forms with in principle, as in this case, the flanges resisting mainly bending forces and the web(s) resisting mainly shear forces.
Figure 2 shows the cut line 3 and fold lines 4 (shown dotted) required to form a rectangular hole through a web with longitudinal stiffening After a cut along line 3 is made the waste area 5 is removed The web is now folded along lines 4 so that the protruding material, which in this instance is at right angles to the web, forms a stiffener to the top and bottom edges of the rectangular hole.
Figure 3 illustrates the completed rectangular web perforation including two stiffeners 6 which are formed solely from a portion of the web material.
A further embodiment of the invention which provides the means of connecting an incoming beam to a portion of folded web plate will now be described by way of example with reference to the drawing sheet 3 17 in which:
Figure 4 shows a beam in elevation with web cut and fold lines.
Figure 5 shows an isometric view of the completed connecting bracket.
The web is cut along line 3 as indicated in Figure 4 The web is then folded along line 4 (shown dotted) so that the protruding material is in this instance at right angles to the web thus forming a bracket.
Figure 5 illustrates the completed bracket 7 formed solely from a portion of the folded web plate with, in this instance, holes 9 to facilitate fastening of the incoming beam 10.
A further embodiment of the invention which provides the means of supporting a floor from portions of folded web plate will now be described by way of example with reference to the drawing sheet 4 / 7 in which:
Figure 6 shows a beam in elevation with web cut and fold lines.
Figure 7 shows an isometric view of the floor plate supported from the beam web.
The web is cut along lines 3 as indicated in Figure 6 The web is then folded along lines 4 (shown dotted) so that the protruding material is in this instance at right angles to the web In this example floor plate is supported on both sides of the web necessitating successive web plate folds to be made in the opposite direction to the one before.
Figure 7 illustrates the completed brackets 7, formed solely from portions of folded web material, supporting the floor 8 on both sides of the beam.
A further embodiment of the invention which provides the means of stiffening the web by using a portion of folded web plate will now be described by way of example with reference to the drawing sheet 5 /7 in which:
Figure 8 shows a beam in elevation with web cut and fold lines.
Figure 9 shows an isometric view of the stiffened web plate.
The web is cut along line 3 as indicated in Figure 8 The web is then folded along line 4 (shown dotted) so that the protruding material is in this instance at right angles to the web.
Figure 9 illustrates the completed web stiffener 6 formed solely from a portion of folded web material which for instance could be used to reinforce the web from a load 9.
A further embodiment of the invention which provides a seating bracket to aid erection of an incoming beam by using a portion of folded web plate will now be described by way of example with reference to the drawing sheet 617 in which:
Figure 10 shows a column in elevation with web cut and fold lines.
Figure 11 shows an isometric view of the seating bracket.
The web is cut along line 3 as indicated in Figure 10 The web is then folded along line 4 (shown dotted) so that the protruding material is in this instance at right angles to the web.
Figure 11 illustrates the completed bracket 7, acting as an erection aid and formed from a portion of folded web material with, in this instance, a hole 9 to facilitate temporary fastening of the incoming beam 10.
A further embodiment of the invention which provides the means for end connecting a member to another member by using a portion of folded web plate will now be described by way of example with reference to the drawing sheet 717 in which:
Figure 12 shows a beam in elevation with web cut and fold lines.
Figure 13 shows an isometric view of the end connection.
The web is cut along line 3 as indicated in Figure 12 The web is then folded along line 4 (shown dotted) so that the protruding material is in this instance at right angles to the web In this example the lower part of the web is folded in the opposite direction to the upper part of the web although the web may also be folded in one or multiple directions to suit the required application.
Figure 13 illustrates the completed end connection formed solely from a portion of folded web material which, in this instance, is holed 9 to facilitate fastening to another structural member.
Claims (9)
1 A modification to the webs of structural members which utilises the material of the web itself to form stiffening or support functions This is achieved by making suitable cuts in the web so that a portion of material from the web may be folded out of plane to perform the required function.
2 The web modification as claimed in Claim 1 where a portion of web material is folded so that the protruding material is out of plane with the web to form reinforcement to a web cut out.
3 The web modification as claimed in Claim 1 where a portion of web material is folded so that the protruding material is out of plane with the web to form a bracket which allows the connection of an incoming structural member.
4 The web modification as claimed in Claim 1 where a portion of web material is folded so that the protruding material is out of plane with the web to form a support bracket for a horizontal floor within the web depth.
The web modification as claimed in Claim 1 where a portion of web material is folded at right angles to the web so that the protruding material provides enhanced stiffening to the web.
