Definitions

  • COMPOSITE FLOOR UTILIZING THE SAME Inventor: Bernard E. Curran, SeWickley, Pa.
  • Field installed studs are inherently more expensive than factory installed studs. Moreover the studs are only effective when they are structurally integral with the building framework, i.e., the beam itself. Accordingly, it has been necessary to provide gaps in the flooring sections for shear connectors. See, for example, Journal of the American Concrete Institute, TA 68l.A 61 Volume 18, Number 3, (November 1946) pages 241-248. Alternatively, it has been necessary to provide drilled, burned or punched holes in the sheet metal flooring to provide direct welding of the studs to the metal beam. See, for example, Civil Engineering, TA l.C6l, (October 1961) page 69.
  • the principal object of this invention is to provide an improved flooring section for use in composite floor constructions of the type utilizing welded studs.
  • Another object of this invention is to provide a corrugated flooring section having improved closure means for closing the opposite ends of the corrugation against ingress of a subsequently poured layer of concrete and which exposes upper surface portions of a subjacent horizontal beam for the installation of shear transfer elements directly to the horizontal beam.
  • the present invention provides a corrugated flooring section having improved closure means for closing the opposite ends of the corrugation.
  • the improved closure means is formed solely from segments of the flooring section.
  • the closure means closes the ends of the corrugations along closure edges which are substantially entirely inwardly offset from a line coincident with the transverse end of the flooring section.
  • the present flooring sections are erected in end-toend abutted relation with the confronting transverse end overlying a horizontal beam.
  • the flooring sections are secured to the horizontal beam along contiguous portions thereof by plug thereof,
  • the opposed closure means of corresponding corrugations expose upper surface portions of the horizontal beam.
  • a shear-transferring stud is applied directly to each or selected ones of the exposed surface portions of the horizontal beam.
  • the shear-transferring studs connect the layer of concrete to the subjacent beams thereby achieving composite beam construction.
  • shear-transferring studs has been limited to corrugated flooring sections having a height of about 1.5 inches. Studs in 3 inch high decking have been ineffective because of lack of embedment.
  • the closure means of this invention may be provided in corrugated flooring sections having a height of 1% to 3 inches. A flooring section having a height of 3 inches and incorporating the present closure means, may be assembled in a flooring structure with shear-transferring studs. The present closure means permit sufficient embedment of the studs to enable the studs to achieve full efficiency.
  • FIG. 1 is a broken plan view of a flooring section incorporating closure means of this invention
  • FIG. 2 is a fragmentary perspective end view illustrating the closure means of this invention
  • FIG. 3 is a cross-sectional view taken along the line 3-3 of FIG. 2;
  • FIG. 4 is a fragmentary perspective view further illustrating the flooring section of FIG. 1;
  • FIG. 5 is a fragmentary perspective view of an alternative three-channel flooring section
  • FIG. 6 is a fragmentary perspective illustration of a floor construction utilizing the present flooring sections and composite beam construction
  • FIG. 7 is a fragmentary plan view of a floor construction of FIG. 6 further illustrating the installation of the shear-transferring studs.
  • FIG. 8 is a cross-sectional view taken along the line 8-8 of FIG. 7, illustrating the embedment of the sheartransferring stud in a layer of concrete.
  • FIGS. 1 and 4 illustrate a flooring section 10 having opposite transverse ends 11, 12.
  • Marginal connecting means such as a male lip 13 and a female lip 14 are formed along the opposite longitudinal sides of the flooring section 10 and adapt the flooring section 10 for side-by-side connection with adjacent flooring sections.
  • the flooring section 10 is corrugated and presents alternating coplanar rectangular crests l5 and coplanar rectangular valleys 16 and generally vertical webs 17 connecting adjacent ones of the crests l5 and valleys 16.
  • the flooring section additionally includes side valleys 16a, 16b terminating in the male lip 13 and female lip 14, respectively.
  • each trough 18 is defined by one of the crests 15 and the adjoining side walls 17 and is presented at one face of the flooring section 10
  • each trough 19 is defined by one of the valleys l6 and the adjoining side walls 17 and is presented at the opposite face of the flooring section 10.
  • closure means 21 are provided for substantially entirely closing the opposite ends of the lengthwise troughs 18 (FIG. 4).
  • each of the closure means 21 comprises end segments, such as, a crest end segment 22 and web end segments 23, one on each side of the crest end segments 22.
  • the crest end segment 22 extends from the adjoining crest 15 toward the common plane 20 (FIG. 3).
  • the web end segments 23 extend from the adjoining web 17 toward the common plane 20 (FIG. 3).
  • Each web end segment 23 adjoins the crest end segment 22 along a common side 24 (FIG. 2).
  • closure edges 25 are substantially flush with the common plane 20. It will be observed in FIG. 2 that the closure edges 25 consist of the adjoining lower edges of the crest end segment 22 and the web end segments 23. Moreover, the closure edges 25 extend uninterruptedly between the valleys positioned on opposite sides of the closure means 21.
  • the flooring section 10 of FIG. 4 is a four-channel element having a height indicated at 27 and equal to, for example, 1% inches.
  • FIG. 5 illustrates a three-channel flooring section 28 having a height indicated at 29 which is greater than the height 27 of the flooring section 10 of FIG. 4.
  • the flooring section 28 may have a height of 3 inches or more.
  • the flooring section 28 is provided with closure means 21 for substantially entirely closing the lengthwise troughs 18 defined by the crests l5 and adjoining side walls 17.
  • FIG. 6 illustrates a floor structure 30 having first flooring sections 10A assembled in side-by-side connected relation and resting on a building framework 31 of which only horizontal beams 32 are illustrated.
  • the corresponding transverse ends of the first flooring sections 10A overlie the top flange 33 of the horizontal beam 32.
  • Each of the valleys 16 of the flooring sections 10A are secured to the horizontal beam 32 by one or more fusion welds 34.
  • second flooring sections 108 are similarly erected and secured to the top flange 33 by plural fusion welds 34.
  • the closure means 21A, 21B of the adjacent flooring sections 10A, 108 are disposed in confronting relation to expose upper surface portions 35 of the top flange 33 of the horizontal beam 32.
  • the surface portions 35 provide sites for the fusion welding of shear-transferring studs 36 directly to the top flange of the horizontal beam 32.
  • the shear-transferring stud 36 can be quickly applied to the surface portion 35 by means of electric arc stud welding equipment which consists of a welding gun which receives the stud.
  • the loaded welding gun is positioned against the surface portion 35 (weld-site) and actuated.
  • An electric arc fuses the weld-site metal.
  • the gun plunges the stud into the molten puddle to achieve a rugged, secure stud attachment.
  • Typical studs 36 have a shaft diameter of 0.5 1.0 inch and a head diameter of 1.0 2.0 inch.
  • the head of the stud 36 is maintained above the crests 15 and at least 1 inch below the upper level of the subsequently poured concrete 37.
  • the function of the studs 36 is to transfer shear stresses from the concrete 37 (FIG. 8) directly to the subjacent horizontal beam 32. According to the present invention, the studs 36 are fully efficient for this purpose.
  • the relatively large space 38 (FIG. 8) made available by the confronting closure means 21A, 21B of the present flooring sections 10, permits sufficient embedment of the stud 36 to enable it to achieve full efficiency.
  • the flooring sections 10, 28 may be equipped with crest deformations 39 and web deformations 33 (FIG. 5) of the type described in Canada Pat. No. 704,842 to achieve composite floor construction in addition to composite beam construction.
  • flooring sections 10, 28 of FIGS. 4, 5 are shown with four and three crests 15, respectively, it should be apparent that more or fewer crests could be provided.
  • the minimum condition is where a single crest 15 and a pair of lateral valleys is presented.
