Abstract
Description
- The present invention relates to the construction of composite slabs that include:
-
- (a) profiled metal sheets; and
- (b) a layer of hardened concrete or other suitable castable material on the sheets.
- A major, although not the only, end use application of such composite slabs is as floors in buildings (which term includes car parks).
- Another, although not the only, end use application of such composite slabs is as vertical wall panels.
- Usually, profiled metal sheets include:
-
- (a) parallel longitudinal ribs that are separated by pans; and
- (b) male and female members at opposite sides of the sheets that enable adjacent sheets to be connected together in overlapping relationship by inserting a male member into a female member.
- One of the failure modes of composite slabs is by longitudinal slip between profiled metal sheets and concrete or other castable material on the sheets.
- An object of the present invention is to provide a composite slab that has improved longitudinal slip resistance compared with that of composite slabs known to the applicant.
- In general terms, the present invention provides a profiled metal sheet for use in the construction of composite slabs. The sheet includes a plurality of parallel longitudinal ribs separated by pans and male and female members at opposite sides of the sheet that enable adjacent sheets to be connected together in overlapping relationship. At least one of the ribs, male members and female members has a side that extends from the pan that is adjacent the rib or the member. The side includes a re-entrant section and a corner section that connects the side and the adjacent pan. The corner section includes a plurality of regions at spaced intervals along the length of the corner section that extend outwardly compared with adjacent regions of the corner section. The spaced regions are provided to improve longitudinal slip resistance of composite slabs formed from the sheet.
- In more specific terms, according to one aspect of the present invention there is provided a profiled metal sheet that includes: a plurality of parallel longitudinal ribs separated by pans, and male and female members at opposite sides of the sheet that enable adjacent sheets to be connected together by inserting a male member into a female member, at least one of the male and female members having a side that extends from the pan that is adjacent the member, the side including a re-entrant section, and a corner section that connects the side and the adjacent pan, and the corner section including a plurality of regions at spaced intervals along the length of the corner section that extend outwardly compared with adjacent regions of the corner section.
- According to another aspect of the present invention there is provided a profiled metal sheet that includes: a plurality of parallel ribs separated by pans, and male and female members at opposite sides of the sheet that enable adjacent sheets to be connected together by inserting a male member into a female member, each rib having a pair of opposed sides that extend from adjacent pans, at least one side including a re-entrant section, and a corner section that connects each side and the adjacent pan, and one corner section at a side that has a re-entrant section or at least one such corner section including a plurality of regions at spaced intervals along the length of the corner section that extend outwardly compared with adjacent regions of the corner section.
- According to another aspect of the present invention there is provided a profiled metal sheet that includes: a plurality of parallel ribs separated by pans, and male and female members at opposite sides of the sheet that enable adjacent sheets to be connected together by inserting a male member into a female member, each rib having a pair of opposed sides that extend from adjacent pans, at least one of the male and female members having a side that extends from the pan that is adjacent the member, at least one side of the ribs including a re-entrant section, at least one side of the male and female members including a re-entrant section, and a corner section that connects each side of the ribs and the male and female members and the adjacent pans, and one corner section at a side that has a re-entrant section or at least one such corner section including a plurality of regions at spaced intervals along the length of the corner section that extend outwardly compared with adjacent regions of the corner section.
- The applicant has found that the combined effect of the re-entrant sections and the outwardly extending regions improves the longitudinal slip resistance of composite slabs formed using the above described profiled metal sheets.
- Specifically, the re-entrant sections lock together the concrete or other castable material and the sheet.
- In addition, the location of the outwardly extending regions in the corner section or corner sections of the ribs and/or of the male members and/or of the female members is such that, when concrete slips longitudinally relative to the sheet and thereby generates lateral forces against the outwardly extending regions (which tend to push the regions inwardly), tensile stresses develop in the sheet transversely to the longitudinal direction of the ribs in response to the lateral forces, and the tensile stresses resist the concrete-generated lateral forces.
- The applicant has found that such tensile stresses are not generated to the same extent with profiled metal sheets of composite slabs known to the applicant.
- The outwardly extending regions may be any suitable shape.
- Preferably the outwardly extending regions are in the form of crimps.
- Preferably the crimps extend transversely to the lengthwise direction of the ribs.
- The outwardly extending regions may be formed by any suitable means.
- By way of example, the outwardly extending regions may be roll-formed in the profiled metal sheet.
- Preferably the outwardly extending regions extend at least 4 mm beyond adjacent regions of the corner section.
- More preferably the outwardly extending regions extend at least 5 mm beyond the adjacent regions.
- Preferably the spacing between the outwardly extending regions is at least 15 mm.
- More preferably the spacing between the outwardly extending regions is at least 30 mm.
- It is preferred particularly that the spacing between the outwardly extending regions be at least 50 mm.
- Preferably the spacing between the outwardly extending regions is less than 95 mm.
- More preferably the spacing between the outwardly extending regions is less than 80 mm.
- If the spacing between the outwardly extending regions is too small, the longitudinal shear resistance of concrete between the regions will be relatively low and the concrete will tend to shear.
- On the other hand, if the spacing between the outwardly extending regions is too large, the outwardly extending regions will not provide sufficient resistance to longitudinal slip.
- The re-entrant section may form a small part only of the side of the rib or the male member or the female member.
- At the other extreme, the re-entrant section may form substantially all of the side of the rib or the male member or the female member.
- Preferably the opposed sides of each rib extend generally upwardly and inwardly towards each other from the adjacent pans.
- According to the present invention there is also provided a composite slab that includes the above-described profiled metal sheet and a layer of hardened concrete or other suitable castable material on the sheet.
- The present invention is described further by way of example with reference to the accompanying drawings, of which:
-
FIG. 1 is a perspective view of one embodiment of a profiled metal sheet in accordance with the present invention; -
FIG. 2 is an end elevation of the sheet shown inFIG. 1 ; -
FIG. 3 is an enlarged end elevation of a part of a composite slab formed from the sheet shown inFIG. 2 which illustrates the forces generated by longitudinal slip of concrete relative to the sheet; and -
FIG. 4 is an enlarged end elevation of a part of a composite slab formed from another embodiment of a profiled metal sheet in accordance with the present invention. - The profiled metal sheets shown in the figures are described hereinafter in the context of the construction of composite floor slabs that include the profiled metal sheets and a layer of concrete on the upper surface of the sheets (as viewed in the figures).
- The profiled metal sheet shown in
FIGS. 1 to 3 is formed by roll-forming a flat sheet of steel. - The sheet includes two longitudinal parallel ribs generally identified by the
numeral 5 separated byflat pans 7. - The sides of the sheet are formed as a male connection member 9 and a
female connection member 11. - The arrangement of the male and
female members 9, 11 enables adjacent sheets to be positioned together in overlapping relationship with a leak proof lap join by inserting the male member 9 of one sheet into thefemale member 11 of the adjacent sheet. - Each
rib 5 of the sheet includes atop flange 13 which separates two sides, generally identified by thenumeral 15. - Each
side 15 includes afirst section 17 that extends outwardly and downwardly from thetop flange 5, asecond section 19 that extends downwardly and inwardly from the lower edge of thefirst section 17, and athird section 21 that extends downwardly and outwardly from the lower edge of thesecond section 19 and connects the side and theadjacent pan 7. - The junction of the
third section 21 and thepan 7 forms acorner section 21. Preferably the angle of thecorner section 21, as described by thethird section 21 and thepan 7 is between 70-100°. - The junction of the
second section 19 and thethird section 21 forms acorner section 33. Preferably the angle described by thesecond section 19 and thethird section 21 less than 100°, more preferably less than 90°. - The
second section 19 defines a re-entrant section of therib 5. - The sheet further includes a series of
regions 23 in thecorner 21 on the left side of theleft rib 5 shown in the figures. Theregions 23 are provided to cooperate with there-entrant sections 19 of theribs 5 to contribute to the longitudinal slip resistance of a composite slab formed from the sheet and concrete and other suitable castable material on the sheet. Theregions 23 are at spaced intervals along the length of thecorner 21. - The
regions 23 are outwardly extending, regions when compared with adjacent regions of thecorner 21. - Preferably the spacing of the
regions 23 is 30-80 mm. - Preferably the
regions 23 extend outwardly at least 5 mm from adjacent regions of thecorner 21. - The
regions 23 are provided to cooperate with there-entrant sections 19 of theribs 5 to contribute to the longitudinal slip resistance of a composite slab formed from the sheet and concrete and other suitable castable material on the sheet. As described above, there-entrant sections 19 lock together the sheet and the concrete. More particularly, as shown inFIG. 3 , the concrete generates a bearing force F1 against thecorner 33 of there-entrant section 19 and thethird section 12 of therib 5 shown in the Figure. In effect, the bearing force F1 pins thecorner 33. In addition, when there is longitudinal slip of concrete that generates lateral forces that act against theregions 23, tensile stresses are generated in sections of the sheet that are in the immediate vicinity of theregions 23 in response to the lateral forces, and the tensile stresses counter the lateral forces and resist inward movement of theregions 23. With reference toFIG. 3 , the lateral forces are identified by the letter F2 and the tensile stresses are identified by the letter T. - The overall effect of the tensile stresses is that the sheet has very high longitudinal slip resistance.
-
FIG. 4 illustrates an enlarged section of a composite slab that includes another embodiment of a profiled metal sheet. - As with the sheet shown in
FIGS. 1 to 3 , the sheet shown inFIG. 4 includes arib 5 that has atop flange 13 which separates twosides 15. - The
sides 15 also include re-entrant sections. However, in this embodiment thesides 15 form a dovetail formation, whereby in effect the re-entrant sections are substantially all of thesides 15. Nevertheless, the forces acting on the sheet are the same for both embodiments. - Many modifications may be made to the preferred embodiment of the present invention described above without departing from the spirit and scope of the invention.
- By way of example, whilst the embodiment described above in relation to
FIGS. 1 to 3 include outwardly extendingregions 23 along the length of thecorner 21 on the left side of theleft rib 5 shown in the figures, the present invention is not limited to this arrangement and theregions 23 may be provided in any one or more of thecorners 21 of theribs 5. - In addition, the present invention extends to arrangements in which one or both of the male and
female members 7, 9 include re-entrant sections and outwardly extending regions in the corners of the male andfemale members 7, 9. - In addition, the present invention extends to other profiles of ribs and male and female members which have re-entrant sections.
