Definitions

  • an object of the present invention to provide an insert for pre-cast concrete or the like which is capable of self-positionment and exposure of a surface thereof relative to one face of the pre-cast concrete to facilitate attachment of a fastening element thereto, and at the same time provide a concrete void immediately behind the exposed surface which offers substantially no resistance to a fastening element assembled to the concrete insert.
  • Another object of the present invention is the provision of an insert for pre-cast concrete or the like which alfords wide flexibility in both site alignment as well as the assembly of sections made from different types of material to the pre-cast concrete at a variety of locations.
  • an insert for pre-cast concrete or the like which includes a top wall and side wall depending therefrom on opposite sides thereof to define a channel-shaped member, and a floating element mug within the channel-shaped member to position at least outer marginal surfaces of the top wall thereof substantially flush with the top surface of the concrete adjacent the insert prior to the setting of the concrete, the floating element also being capable of providing a concrete void immediately behind the top wall of the channel-shaped member and having substantially no resistance to a fastening element driven therein during attachment thereof to the top wall of the channel-shaped member.
  • the floating element which may also be characterized as the secondary element of the concrete insert, may also be capable of being received and retained by the channel-shaped member.
  • FIG. 1 is a perspective view of the preferred form of concrete insert which is constructed in accordance with the teachings of the present invention
  • FIG. 2 is a fragmentary perspective view illustrating the manner in which concrete inserts, either in block or in stripform, of the type depicted in FIG. 1 are capable of being mounted into a pre-cast concrete support or the like;
  • FIG. 3 is an enlarged fragmentary end elevational view as viewed along line 33 in FIG. 2;
  • FIG. 4 is an end elevational view showing the manner in which a fastening element is mounted relative to the concrete insert and holds a pre-cast concrete panel relative to the pre-cast concrete support in which the concrete insert is mounted;
  • FIG. 5 is an end elevational view showing a modified form of concrete insert which is used in conjunction with a corrugated metal panel and concrete support assembly.
  • the concrete insert 10 includes a primary metal channel-shaped member 12 into which is mounted a secondary element 14 which is designed to provide floatation of the concrete insert 10 prior to setting of the concrete into which it is positioned and at the same time provide a concrete void immediately behind the top wall 16 of the channel-shaped member for reasons which will appear hereinafter.
  • the secondary element 14 can be configured or made from any material which will provide floatation and concrete void features just mentioned, it has been found that foamed polystyrene block material which is illustrated in FIGS. 1-4 of the drawings or gypsum are preferred constructions.
  • the foamed polystyrene blocks 14 are formed in a generally rectangular cross-sectional shape and mounted within the channel-shaped member 12 as illustrated in the drawings.
  • the metal channel-shaped member may be made from sheet steel such as AISI 1010 in suitable thicknesses as desired.
  • the channel-shaped member 12 is formed by suitable dies as a one-piece construction and includes a top wall 16 with side walls 18 depending therefrom on opposite sides thereof, each side wall 18 terminating in a foot portion 20 at the free extremity thereof which may be aligned, if desired, with the lower face of the foamed polystyrene block 14.
  • Each of the side walls 18 flare or taper downwardly and outwardly from adjacent the juncture with the top wall 16 to facilitate introduction of the foamed polystyrene block 14 within the channelshaped member.
  • each of the side walls 18 immediately adjacent the juncture with the top wall 16 first are directed downwardly for a short distance, then proceed downwardly and outwardly as illustrated. This permits the foamed polystyrene block to completely underlie the top wall 16 if it is configured to fill up the space as illustrated in the drawings so that there will be no concrete immediately below the top wall 16 of the channel-shaped member.
  • the channel-shaped member includes means for holding the foamed polystyrene block 14 therewithin.
  • such means may comprise an integral tab 24 struck from each of the side walls 18 and extending upwardly and inwardly relative thereto for engaging and retaining the foamed polystyrene block 14 within the channel-shaped member as best seen in FIG. 3 of the drawing.
  • each of the tab means is integrally hinged relative to a respective side wall along a line generally coincident with the juncture of the side wall 18 and associated foot portion 20.
  • each of the tabs 24 are flexibly and hingedly mounted so as to provide the desired flexibility upon mounting of the foamed polystyrene block 14 within the channel-shaped member, but upon the complete interfitting movement of such components, the tabs 24 on each of the side walls 18 function as struck elements to prevent removal of the foamed polystyrene block 14. In this way, the foamed polystyrene block 14 is captured by the channel-shaped member 12 so that there will be no disassembly during use of the concrete insert.
  • each of the side walls 18 which are formed by the integral tabs 24 being struck from the side walls 18 enhances the retention of the concrete insert Within a concrete support 22. It will be readily understood that the concrete can easily flow through the apertures 26 so as to be positioned on opposite sides of each side wall 18, foot portion 20 and tab 24 as best seen in FIG. 3 to effectively retain the insert within the concrete support.
  • the concrete insert will float during the concrete pour such that the top wall 16 of the channel-shaped member 12 can be positioned flush with the top surface or outer face of the concrete support 22. This is important in providing a large surface area over which a fastening device, such as the self-drilling and tapping screw 28 shown in FIG. 4, can be attached to the top wall of the channel-shaped member 12.
  • a fastening device such as the self-drilling and tapping screw 28 shown in FIG. 4
  • US. Pat. 3,125,923 where such a fastening element is used for attachment to the top wall of the channelshaped member 12, it is also important that there be a concrete void immediately behind the top wall 16 which offers substantially no resistance to a fastening element driven therein during attachment to the top wall 16.
  • a fastener device such as the selfdrilling and tapping screw 28 must be capable of penetrating the top wall 16 and attach itself relative thereto by tapping threads in the aperture which is formed by the self-drilling fastener 28 without encountering any substantial resistance beneath the top wall 16 of the channelshaped member 12 which could substantially hinder and reduce the desirability of using the concrete insert 10. All of the above features are obtained with the use of the concrete insert of the present invention. It will be noted that the concrete section 30 has a tapered hole 32 which aids in aligning the self-drilling and tapping fastener 28 or other equivalent fastener device during attachment to the concrete insert.
  • the concrete insert 10 of the present invention can be formed into short sections as shown at the left hand side of FIG. 2 or, alternatively, may be formed into elongated metal strips which are shown at the right hand side of 4 FIG. 2.
  • the concrete insert can be formed in a variety of configurations, including closed figures, if such is desired.
  • FIG. 5 of the drawings wherein the foamed polystyrene block or secondary element 14 is replaced by a complementary channel-shaped element 34 which is inverted with respect to the channel-shaped member 12, but is positioned within and retained by the channel-shaped member 12 in substantially the same manner as the foamed polystyrene block 14 in the FIGS. 14 embodiment.
  • the inverted channel-shaped element 34 as will be seen in FIG. 5 of the drawings, clearly provides a concrete void immediately behind the top wall 16 of the channel-shaped member 12 which offers no resistance to a fastening element such as the self-drilling and tapping screw 32.
  • FIG. 5 also illustrates the use of the concrete insert 10 attaching corrugated metal strips 34 to the concrete support 22 by way of the self-drilling and tapping fastener 32 as illustrated.
  • the concrete insert 10 provides the capability of attaching sections of different material and configurations to a concrete support as will be readily apparent.
  • While a self-drilling and tapping fastener 32 may be used in conjunction with the concrete insert 10, it is also possible that various types of fastening devices may be captured within or attached to the top wall 16 of the channel-shaped member to permit attachment of various types of sections to the concrete support in which the concrete insert 10 is positioned. Other types of fastening components or extensions, either integral with or attached to the top wall 16 of the channel-shaped member 12 may be used as desired.
  • a fastening insert for concrete comprising a channel-shaped section including an end wall integrally connected to generally opposed side walls, said side walls including generally opposed portions substantially normally directed relative to said end wall portion and portions generally flaring outwardly from said substantially normally directed portions, said flaring portions facilitating introduction of a secondary element within said channel-shaped member, said secondary element being a body of material cooperatively mounted within said side Walls and capable of creating a concrete void immediately behind the end wall thereof to enable a complementary fastening element to be driven therein without offering any substantial resistance to said complementary fastening element during attachment thereof to the end Wall of said channel-shaped member, means formed in at least one of said side Walls to retain said complementary element within the channel-shaped member, said side walls being laterally spaced from said secondary element for at least a part of the axial height thereof, and outwardly directed foot portions at the terminating extremities of said flaring portion, said aforesaid means for retaining said secondary element within said channelshaped member being a tab extending from the vicinity of the juncture of said out
  • a fastening insert for concrete comprising a channel-shaped section including an end wall integrally connected to generally opposed side walls, said side walls including generally opposed portions substantially normally directed relative to said end wall portion and portions generally flaring outwardly from said substantially normally directed portions, said flaring portions facilitating introduction of a secondary element within said channel-shaped member, said secondary element being a body of material cooperatively mounted within said side walls and capable of creating a concrete void immediately behind the end wall thereof to enable a complementary fastening element to be driven therein without offering any substantial resistance to said complementary fastening element during attachment thereof to the end Wall of said channel-shaped member, means formed in at least one of said side walls to retain said secondary element within the channel-shaped member, said side Walls being laterally spaced from said secondary element for at least a part of the axial height thereof, and outwardly directed foot portions at the terminating extremities of said flaring portion whereby said foot portions and the generally opposed side wall portions cooperate to securely retain the insert imbedded in the concrete when said fastening element is attached to the end wall of said channel
  • said generally opposed means comprises a pair of opposed tab means which extend inwardly and are inclined relative to the side wall with which such tab means is associated.
  • the fastening insert as defined in claim 2 said fastening insert being secured to a pre-cast concrete support, a section to be attached to the concrete support, and a headed fastening device which attaches the section to the concrete support, said section having a tapered hole extending therethrough which is configured and arranged relative to the head of the fastening device to prevent tilting thereof during attachment of the fastening device to the fastening insert.
