  • the invention relates generally to inserts for concrete designed to aid in the attachment of construction materials to concrete.
  • a channel-shaped insert having an exposed surface for receiving a fastener therethrough, a pair of side walls integrally connected to the exposed surface and a cover means generally parallel to the exposed surface which is designed in such a manner as to create a concrete void behind the exposed surface.
  • the invention further includes a seam-like interlocking of various wall portions of the insert to simultaneously impart structural rigidity and insure that liquid and other material does not enter the void behind the exposed surface wall.
  • FIG. 1 is a sectional side view of a precast concrete beam incorporating one form of the invention
  • FIG. 2 is a sectional view of a modification of the concrete insert shown in FIG. 1;
  • FIG. 3 is a sectional view of a second modification of the concrete insert shown in FIG. 1;
  • FIG. 4 is a sectional view of a third modification of the concrete insert shown in FIG. 1;
  • FIG. 5 is a sectional view of a fourth modification of a concrete insert shown in FIG. 1.
  • FIG. 1 an embodiment of the invention is illustrated in a precast concrete beam 32.
  • the insert 10 is shown as a channel-shaped section having an end wall 12, side walls 14 and a cover wall 16. These four walls are configured in such a manner as to produce a void area 20.
  • the cover wall in this preferred embodiment is shown to be constructed from a pair of flap-like portions 17 which interlock with one another at seam l8.
  • the seam 18 forms an effective seal precluding solid foreign matter from entering the void area 20.
  • This preferred embodiment shows flap portions 17 of the cover wall 16 to be tortuously interlocked by overlapping respective portions 24 and 26 of the cover wall 16.
  • the seam means 18 also provides an effective seal against liquid entering the void area 20, since any liquid must take the tortuous path described by the overlapping portions 24 and 26 in order to enter the area 20. It is also apparent that the interlocking wall portions 24 and 26 provide the insert with substantial rigidity and effectively preclude relative movement of the cover wall 16 and the end wall 12 as well as relative movement of the side walls 14. The preclusion of these movements becomes important upon the application of the forces inherent in the flowing of the concrete during construction of the concrete beam, as well as forces applied to the insert through the attachment of various other construction materials, as will be discussed later in the specification.
  • the insert 10 shown embedded in a precast concrete beam 32 is visioned to be constructed from a relatively thin gauge of sheet steel, e.g., 18-25 gauge.
  • a relatively thin gauge of sheet steel e.g. 18-25 gauge.
  • the use of such a thin gauge material necessitates the structural rigidity inherent in a seam such as 18, as discussed above.
  • a series of precast concrete beams 32 may be constructedby placing form members in such a manner as to configure a structure having tapered side surfaces 42 and end surface 36.
  • the insert 10 may be placed longitudinally of the form, with end surface 12 contacting the portion of the form which ultimately will form surface 36 of the concrete beam.
  • concrete may be poured or flowed around sides 14 and cover wall 18 while leaving end wall 12 exposed upon the removal of the forms.
  • the seam means 18, will preclude aggregate or water, from the concrete, to enter the area 20.
  • the interlocking wall portions 24 and 26 will likewise insure thestability of theinsert and will preclude appreciablemovement of portions of the insert due to the forces exerted upon it by the flowing concrete.
  • the beams 32 Upon the setting up of the concrete, the beams 32 then may be covered by gypsum board 38 or the like by readily inserting fasteners 40 through the boards 38 and end wall 12, and subsequently into the void area 20.
  • the only resistance to entry into the composite concrete beam thus being the entry of the fastener through the relatively thin end wall 12.
  • the concrete insert is effectively precluded from being pulled out by external forces, such as that presented by the hanging of wallboard 38 or the like, by the provision of portions 23 of the wall 14.
  • Portions 22 are shown to flare outwardly from the side wall thus allowing the concrete to be formed above these tapered portions and presenting an effective resistance to removal of the insert from the concrete beam.
  • FIG. 2 describes an alternate embodiment wherein the insert 10a includes an end wall 12a, side walls 14a and a separate cover wall 16a.
  • the cover wall 16a is connected to the remainder of the insert by interlocking seams 18a.
  • These seams 18a are shown to flare outwardly from the side walls 14a to inherently provide the pullout resistance described similar to portions 22 above.
  • the seams 18a are shown to extend in a plane which extends at an angle to the end all 12a of between zero and ninety degrees. These seams 18a will thus effectively seal the insert as well as provide the insert with rigidity in both horizontal and vertical directions.
  • the seal 18a includes a tortuous interlock similar to that described with regard to seal 18 above.
  • FIG. 3 describes a second alternate embodiment of the insert 10b which likewise includes a cover wall 16b integrally connected to one of the sides 14b in a flaplike arrangement.
  • the side walls 141) are integrally connected to the end wall means 12b, thus providing a one piece insert, as was provided by the insert 10.
  • the seam 18b is shown to interconnect the extremity of the flap-like cover means 16b to theextrernity of one of the sides 14b in a tortuously interlocking fashion.
  • the seam 18b is shown to extend in a diagonal plane to the end wall 12b to provide structural rigidity in both vertical and horizontal directions, as well as inherently provide the insert with the pullout resistance described above.
  • the opposite wall 14b includes a flared portion 221) for the same function.
  • FIG. 4 describes a third alternate embodiment of the invention 10c which is similar to that described in FIG. 3, except the seam 180 is not formed in such a manner as to provide a flared configuration on both sides of the insert, even though the protrusion of this seam into the concrete will inherently provide resistance to pullout.
  • Insert 100 includes a portion 22c flaring outwardly from one of the walls 14c while the other wall 14c terminates in a tortuously interlocking seam 18c with the terminal portion of the flap-like cover wall 16c. The abutment of the terminal wall portions comprising the 4 interlocking seam will also rigidify the insert against horizontal and. vertical movement of various components of the insert relative to one another.
  • FIG. 5 presents a fourth embodiment of the invention in the form of insert 10d.
  • the insert 10d includes a cover wall 'means 16d, end wall 12d, side walls 14d, with portions 22d of the-side walls flaring outwardly.
  • One of said walls comprises inner and outer walls 28 and 29 which are placed in overlapping, closely juxtaposed positions to one another.
  • the inner wall 28 includes a portion-44 flaring outwardly therefrom to remain in close juxtaposition with the flared portion 22d of the outer wall 29.
  • the portion of the outer wall 29 nearest the end wall 12d includes a small lip-like portion 30 which overlaps the end wall to complete a tortuous seam-like interlock between the inner and outer walls, the cover wall and the end wall. It is apparent that compression forces will not'appreciably distort the insert due to the abutment of the upper extremity of the flared portion 44 with the inner surface of the juncture of the cover wall 16d and .the outer side wall 29. It is also apparent that tension forces on the end wall 16d will not produce appreciable distortion of the insert due to the overlapping portion 30, which prevents movement of the end tive to the cover wall 16d.
  • a concrete insert comprising a one piece channelshaped section of relatively thin gauge sheet steel including a continuous substantially uninterrupted end wall, side walls connected to ,the end wall, cover wall means extending between the side walls for producing a concrete void behind the end wall, said cover wall means and said side walls being embedded in concrete with the end wall exposed and adapted to receive a penetrating fastener therethrough without substantial resistance, at least one of said side walls including a portion flaring outwardly and integrally connected to the cover means, one of said side walls consisting of an inner and outer wall in juxtaposed position, one terminal edge of the channel-shaped section forming an upper extremity for said inner wall and which forms abutment means in conjunction with one comer formed between the cover wall and a side wall to prevent appreciable movement of the end wall towards the cover wall as a result of compression forces applied to the end wall, the outer wall including a lip portion which includes the other terminal edge of the channelwall 12d rela- I nected to the cover wall and the inner wall portion is integrally connected to the end wall,
