Definitions

  • the present invention concerns improvements in the techniques and means for joining the panels in roof structures, flashings, water stops, expansion joints, deck joints, splices and the like.
  • the present invention is particularly concerned with a structural unit which may be used in the aforementioned arrangements or which may be employed in conjunction with other such units through appropriate splicing techniques in the fabrication of relatively large structural expanses capable of use in roofs, walls and other constructions; and adapted in such arrangements to assume various shapes and surface contours not readily possible with building materials conventionally employed.
  • the structural beams in a roof are formed of iron or steel, they will expand at the rate of five sixty-fourths of an inch for every feet of length, for every 100 change in temperature.
  • the change from midwinter to midsummer in the length of the expansion joint would amount to approximately one-half inch. This in many cases has resulted in the popping" of the expansion joint cover along its longitudinal edge where it is affixed to adjacent panels of the roof deck.
  • FIG. 1 is a sectional view of the expansion joint cover installed between adjacent panels of the roof deck.
  • FIG. 2 is a sectional view of the new and improved expansion joint cover.
  • FIG. 3 is an isometric view with the upper layer pulled away to disclose the details of construction utilized in our new and improved expansion joint cover.
  • FIG. I discloses our invention in a sectional view of the improved expansion joint cover as installed between adjacent panels ofa roof deck.
  • Block members 11 and 12 are provided along the edges of the expansion joint to provide nailing strips for the expansion joint cover.
  • the joint per se is actually the space 13 between panels 14 and 15 with the new and improved invention being more properly described as an expan' sion joint cover, covering the joint.
  • the structural members of the roof deck have been left out of FIG. I in order to clarify inventive concepts disclosed herein.
  • FIG. 3 is an isometric view of our new and improved expansion joint cover with the upper flap [6 pulled away for purposes of clarity.
  • two elongated and corrugated strips 17 and 18 are spaced apart from each other along their elongated edges. The strips are enclosed in a covering means illustrated as 19 and 20 respectively that completely envelop the elongated and corrugated strips.
  • the covering means 19 and 20 comprise elongated strips of fabric which have been impregnated or saturate-coated with an elastomer.
  • nylon was used for the fabric and neoprene for the elastomer, however it is understood that the invention is not limited to these materials.
  • the strips are then folded upon themselves along their longitudinal dimension and the corrugated strips 17 inserted between the folds 19a and 19b.
  • the covering means is of sufflcient width that when folded upon itself it extends beyond the edge of the corrugated strip and is adhesively sealed to form a seam edge 21 which runs the entire length of the covering means and is adjacent to the corrugated and elongated strip 17.
  • any type of covering means or envelope could be used to surround the corrugated and elongated strip.
  • strip 17 could be placed within an extrusion die, and the covering I9 extruded around strip 17 as the strip is passed from within the die.
  • this alternate of the invention it would also be necessary to provide a sealing seam 21 as shown in FIG. 3.
  • the corrugated strip 17 is approximately 2 inches in width and is of indefinite length with the neoprene-impregnated nylon being of 6 inches in width so that when folded upon itselfit yields a l-inch searn illustrated at 21. Due to the corrugations present in strips 17 and 18 and the flexible nature of the relatively wide cover strip 16, the expansion joint cover when completed may be rolled upon itself for delivery and installation in a roll of indeterminate length.
  • the relatively wide elongated strip 16 is a laminate material.
  • a laminate is formed of a very thin layer 21 of polyvinyl fluoride plastic, such as that sold Du Pont under the trade name TEDLAR.” This surface part of the laminate is generally 2 mils thick and is bonded to an elastomer or synthetic rubber base 22 which is approximately 38 mils in thickness to provide the approximately 40- mil laminate cover illustrated at 16.
  • FIG. 2 discloses a relatively thick insulating strip 23 that runs the entire length of the expansion joint and is axially aligned with the relatively wide cover strip 16.
  • the insulating strip 23 is adapted to pro vide additional thermal and acoustic insulation and thereby make the expansion joint more soundproof. If such insulating characteristics are not desired, the strip of insulating material may be replaced with a single strip of said laminate material, so that the edges 19a and 19b of the envelope 19 are securely fastened between two layers of laminate material.
  • the lower strip could be a single layer of nonlaminate elastomer.
  • a single strip of laminate material may be utilized between the corrugated strips and their envelopes, or a relatively wide strip may be utilized wherein said strips are attached thereto and as illustrated in FIG. 2 with the insulating strip removed.
  • the relatively wide strip 16 provides the necessary strength and is adapted to withstand the stresses and strains to which the expansion joint would normally be subjected.
  • This strip is capable of an elongation of at least 100 percent and has a tensile strength of 1,000 pounds per square inch.
  • the synthetic elastomer is a synthetic rubber which has the characteristic qualities of natural rubber such as resilience, abrasion resistance, low com pression set and low permeability; and retains these properties to a high degree under long exposure to sunlight, weather, ozone, oxygen, oils, greases, heat and chemicals.
  • the seam edge of envelopes l9 and are sealed between insulating strip 23 and cover strip 16 along their longitudinal edges so that the corrugated strips 17 and 18 are spaced apart from one another and extend beyond the sealed jointbetween strip 23 and strip 16.
  • This seal may be accomplished by means of epoxy or other adhesive or by vulcanizing, or both, in any conventional manner to provide a tight waterproof and durable seal.
  • the expansion joint When the expansion joint is installed as shown in FIG. 1, the upper layer 16 is lifted up out of the way exposing the extended portions of envelope I9 and the corrugated strip 17.
  • the strip When wooden blocks 11 and 12 are utilized, the strip may be installed by means of conventional roofing nails 24 which are driven through the envelope and corrugated strip every 2 to 4 inches along the length of the strip.
  • the strip is free to expand vertically within the corrugations and along the longitudinal axis of the expansion joint. If the base member of the expansion joint expands at a greater rate than the corrugated strip, the corrugated flutes will provide the necessary elongation between the nails or other anchoring means.
  • the expansion is not transmitted longitudinally of the entire strip, but is taken up in short sections between fastening points. Since this expansion is taken up in short sections, the fabric cover 19 always presents a flat surface where it is bonded to the substrate membrane 28.
  • nailing blocks 11 and 12 are provided in the roof deck, the present invention is equally suitable to any other type of construction technique, such as sockets, clips, retaining flanges and the like.
  • the first layer 25 of roofing or stripping felt is applied over the top of the corrugated strip.
  • This joint 26 is then sealed with a cold adhesive, hot asphalt, pitch, or other appropriate adhesive to insure a continuously sealed joint.
  • Cover 16 is then brought over the first roofing ply 25 to form a second joint 27 which may also be sealed by means'of cold adhesive or hot asphalt or pitch. If a colored membrane is applied over the roof panel as is done in decorative roof decks, the latter membrane 27 may be applied over the top of covering strip 16 and secured by adhesive, asphalt or other securing means.
  • membrane 19 is stretched tightly over the corrugated flutes of strip 17 and provides a flat surface between cover 19 and a roofing base 28.
  • This flat surface provides a waterproof seal between the expansion joint cover and the roof base that would not be provided if the corrugated flutes were installed without the envelope.
  • the covering or envelope is extruded or sprayed over the strip, it would be advantageous to provide for at least one flat surface to be formed on said covering to assist in providing the waterproof seal.
  • the corrugated strip 17 may be formed of heavy or lightweight plastic, galvanized iron, copper, aluminum, or other material. Due to the protection provided by envelope 19 it has been desirable to employ galvanized iron which is much more inexpensive than copper and aluminum and provides for the same life of the material.
  • An expansion joint comprising a. a pair of elongate spaced apart block members b. an expansion joint cover member overlying said spaced apart block members, said cover member having a pair of elongate strips, each strip having a first elongate edge, said elongate edges being spaced apart from one another and overlying said elongated block members, flexible means overlying andjoining said first elongate edges, said expansion joint cover member being characterized in that said elongate strips have corrugations transverse to the direction of said elongate edges,
  • fastening means for attaching said strip to said underlying elongated block members, said elongate strips having sufficient resiliency to allow for expansion transverse to the corrugations.
