nvvewron I WILL/AM r. MULLEN @TQW ATTORNEY EXPANSION JOINTS FOR ROOFS REFERENCES TO RELATED APPLICATION This application is a continuation in part of my prior U.S. application for Expansion Joint for Roof, filed Aug. 7, 1969, Ser. No. 848,251, now abandoned.
BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to expansion joints for roofs and more particularly to an improved insertable expansible filler or core element for use in roofjoints and the joint construction. 2. Description of the Prior Art Large roof areas must have provisions to accomodate expansion.
Many different methods and materials have heretofore been proposed and these usually rely on some waterproof but elastic material that will stretch to handle the expansion of the joint and then contract when the joint contracts. Many of the materials proposed are adversely affected by strong sunlight and other exposed weathering conditions including the action of ozone and air so that the materials lose elasticity and otherwise age and deteriorate. The most acceptable systems employ a curb built up above the insulation but these systems are expensive and involve many steps or operations for completion.
One expansion joint of the character referred to above is shown in U.S. Pat. No. 3,093,934 to Underhill, which includes angles and fillet strips with an inverted U-shaped flexible insert and a cover strip of flexible plastic and covering tapes.
Numerous expansion joints similar to the Underhill joint are also available and many other expansion joints have been proposed.
The patent to Thompson, U.S. Pat. No. 1,885,391, shows an expansion joint for concrete pavements in which, in one form a plastic noncompressible filler material, preferably bituminous, fills the lower portion of the space between the slabs and the upper portion of the space is closed but only partially filled by a strip of compressible vulcanized sponge rubber which is flush with the upper faces of the slabs.
In another form of the Thompson disclosure the sponge rubber strip is vulcanized to a pair of sheet metal strips with stamped out anchorage members to be embedded in the concrete slab. Paper strips to prevent entry of wet concrete below the rubber strip are provided and wires may be employed to hold the sponge rubber in compressed condition until the concrete has set when the wires may be cut and withdrawn. Thompson does not have a joint for roofs and cannot obtain any comparable ease of use, multiple seal and protection of the sealing strip as attained by applicant.
Fischer, in U.S. Pat. No. 2,431,385, shows an expansion joint for concrete pavements with the use of a sponge rubber strip with a seepage proofing elastic surface filler around the body but with the filler disposed wholly below the upper and outer surfaces of the pavements. No provision is made in Fischer for a projecting sealing element expanded at its exposed portion to a greater extent than the remaining portion so that the only sealing by the sponge rubber is within the space between the ends of the concrete slabs.
Cooper, in U.S. Pat. No. 3,255,680, shows ajoint for cement pavements which comprises an elongated metal strip with flanges for retention in the concrete'and an elongate block secured to the top of the strip which block is of compressible but slow recovery material such as a polyurethane foam. The top of the block in the finished construction is flush with the top of the pavement.
Rhodes, in U.S. Pat. No. 3,276,334, shows a joint filler strip of expansible material which also has no provision for expansion externally of the slab and thus has only a limited character of seal.
My prior U.S. Pat. No. 3,446,340, shows the use of a central highly compressed sealing strip with a finished C-shaped cover or binder strip thereon which are wholly within the space between the panels. The strip and cover do not project therebeyond and if they did could still not expand to provide additional sealing outside the space.
SUMMARY OF THE INVENTION In accordance with the invention an expansion joint is provided which includes an insertable elongated precompressed and reexpansible filler or core element for insertion at joints in a roof deck to a predetermined depth, the lower part and inserted part expanding to fill the space between deck sections and the top part upon release expanding to a greater extent for further sealing with the exposed upper edge protected against sun light, ozone and air.
It is accordingly the principal object of the invention to provide an expansion joint for roofs which includes a precompressed and reexpansible insertable element which can expand to fill the space at the joint and thereabove for engagement with applied roofing.
It is further object of the invention to provide a precompressed expansible sealing element which can be readily transported to the place of use, which will be relatively inexpensive, and which will be easy to use.
It is a further object of the invention to provide a sealing element of the character aforesaid which will provide an effective seal and which will facilitate the construction of an expansion joint for roofs and the like.
It is a further object of the invention to provide an improved expansion joint for roofs in which an expansible filler or core element is employed which simultaneously presses against the roofing, the insulation and the roof deck in sealing relation.
Other objects and advantageous features of the invention will be apparent from the description and claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now more particularly to the drawings and particularly FIG. 1 thereof, a portion ofa filler element employed in connection with the invention is shown at 10 and includes an interior soft highly compressed sealing strip 11. The strip 11 is preferably composed of an open cell polyurethane plastic or similar cellular material which in fully expanded condition is preferably impregnated with a waterproofing and water repellant material which may also be adhesive. Asphalt, butyl and waxes are suitable impregnants. The extent of compression after impregnation will be determined by the nature of the seal which is desired upon subsequent reexpansion, but is such that the joint is at all times sealed by the strip 11 against the passage of water and is capable of responding to changes in the width of the space in which it is used upon either expansion or contraction of the roof deck. A compression of the order of two and one half to one and up to five to one can be employed, depending upon the conditions of use.
The sealing strip 11 is shown as rectangular in cross section, and, along one edge, which is the exposed, edge and a short distance down each side, is provided with a flexible and transversely extensible covering 12, which may be a polyurethane or acrylic coating, to protect the impregnant and the strip 11 from the action of ozone, oxidation by the air, and ultra-violet rays from the rays of the sun.
The sealing strip 11 shown in FIG. 1, is preferably retained in compressed condition prior to use by an elongated inverted U-shaped holding or retainer channel 20, with an interposed release sheet 21 to prevent adherence of the strip 11 to the retainer channel 20. The holding or retainer channel 20 can be made of metal or of synthetic plastic but must have adequate strength to effect its holding action for the sealing strip 11 in compressed condition until release thereof is desired.
The retainer or holding channel 20 preferably has a top section 22 and side legs 23 extending therefrom, preferably of greater depth than that of the strip 1 l.
The mode of use of the filler strip 10 illustrated in FIG. 1 will now be pointed out.
In FIGS. 3 and 4, a roof deck of relatively rigid roof panels 30, which may be of concrete or any other desired material, having insulating panels 31 superposed thereon is shown, with a space 32 therebetween at which an expansion joint is desired. The roof panels 30 have spaced faces 33 and the insulating panels 31 have spaced faces 34.
A filler element 10 shown in FIG. 1, in compressed and unexpanded condition, is prepared for insertion by partial removal of the holding or retainer channel 20 which permits initiation of expansion of the previously confined portion of the strip 11 into sealing engagement with the roof panels 30 and insulating panels 31.
Before expansion occurs the filler element 10 is inserted in the space 32 to the desired depth and limit pins 35 inserted therein atthe desired depth locations. As expansion occurs the strip 11 expands outwardly until it engages the faces 33 and the faces 34.
A plurality of layers 36 of roofing felt with asphalt or pitch, or the like, can be applied over the panels 31, as illustrated in FIG. 3, with asphalt application if desired in the manner well known for built up roofing.
The holding or retainer channel 20 is then completely removed and the removal of the channel 20 will permit the expansion of the unrestrained portion of the strip 11 above the space 32 to expand into sealing engagement with the roofing layers 36 at their edges and flare outwardly thereabove as shown in FIG. 4. The upper edge covering 12 does not prevent this flaring nor the sealing engagement of the portion of the strip 11 therebelow.
Upon change of dimension of the space 32 by expansion and contraction the strip 1 1 in the space 32 will expand and contract without disruption of the sealing with the roofing, the insulation or the roof deck.
Referring now more particularly to FIG. 2 of the drawings, a portion of another filler element in accordance with the invention is there shown at 10a and includes a compressible and reexpansible sealing strip 11 as previously described. 7
The filler element 10a preferably has a covering 12 and is retained in compressed condition by a lower elongated U-shaped retainer channel 24 having a bottom wall 25 and side legs 26. A lower release sheet 21a is interposed between the strip 11 and the channel 24 to facilitate removal of the channel 24 when desired.
An upper cap 24a having a top'wall 22a and side legs 23a contains the upper portion of the strip 11 in compressed condition until it is removed. An upper release sheet 21b is interposed between the strip 11 and the cap 24a to facilitate removal of the cap 24a when desired.
The mode of use of the filler strip 10a illustrated in FIG. 2 will now be pointed out. i
In FIGS. '5, 6 and 7 roof panels 30 and insulating panels 31 are shown as before.
The filler element 10a as shown in FIG. 2 in precompressed and unexpanded condition is prepared for insertion by removal of the retainer channel 24 and, before expansion occurs, is inserted into the space 32 to the desired depth as determined by limit pins 35 inserted therein. The expansion of the portion of the strip 11 in the space 32 occurs until it engages the faces 33 and the faces 34 as illustrated in FIG. 5.
A plurality of layers 36 of roofing felt with asphalt or pitch are applied as illustrated in FIG. 6 and the cap 24a removed to permit the strip 11 to expand into sealing engagement with the roofing layers 36.
The remaining portions of the strip 11 above the roofing paper 36 will expand into a flared shape as before.
If desired, an additional cap layer of roofing felt 37 with asphalt or pitch can then be applied, to cover the exposed and coated upper edge of the strip 1 1.
Upon change of dimension of the space 32 by expansion and contraction the strip 1 l in the space 32 will expand and contract without disruption of the sealing with the roofing, the insulation and the roof deck.
