Description

CORRUGATED DECK SEALING DEVICES, APPARATUS, SYSTEMS AND
METHODS OF INSTALLATION

This invention relates to sleeving systems for openings in floors and walls, in particular to cast in place devices, apparatus, systems and methods of installation for sealing concrete floors poured over corrugated metal decks that are used for plumbing, mechanical, electrical and miscellaneous pipe applications, that seal against water, fire and smoke within the device after the pipe is passed through the device.
BACKGROUND AND PRIOR ART

Concrete floors overlaying corrugated metal decking are increasingly popular in multi-story commercial buildings and condominium buildings. In the past it has been known to extend piping systems through concrete floors by knocking out holes in the floor and boring such holes after the floor has been formed, and then extending pipes through the floors. After the pipes have been inserted into the holes, workman have had to pour additional material such as more concrete or other caulking material to seal up the spaces between the voids and the pipes extending through the voids. However, such attempts to use concrete or caulk to seal up the spaces has not been effective to future problems down the road such as from water leaks and fires and smoke that travel through any void spaces between the floors.

Any water leaks caused by overflowing waterlines, leaks, broken water lines, etc., flow downward around any openings through the flooring that is around pipes.
Such water leaks are known to cause damage to the ceilings and rooms beneath the floor where the openings are around the pipes. This problem becomes compounded in high rises having multiple penetrations on each floor, where large amounts of damage often results Atty Dkt.:

in costly repairs and exasperation, and downtime for the occupants.
Furthermore, constant leaks have been known to cause health hazards since undesirable and dangerous mold and bacteria will form around the leak areas.

Still furthermore, the crevices and cracks about the piping systems in the floors are also a conduit for fires and smoke traveling upward through a multi-floor building.
Again, current sealing techniques that have included concrete and/caulk do not effectively seal these void spaces. In fact, over time natural drying effects and typical pipe movement (thermal expansion and contraction) may shrink any caulk seals which results in opening of the crevices and voids about the plumbing systems causing a pathway for fires and smoke to travel through the floors of the buildings about the plumbing systems.
Over the years various types of systems and devices have been attempted for trying to fix these sealing issues. See for example, U.S. Patents: 2,985,091 to Hatcher;
5,293,724 to Cornwall; 6,314,692 to Munzenberger et al.; 6,405,502 to Cornwall;
6,643,985 to Munzenberger; 6,694,684 and 7,080,486 to Radke et al., and devices sold by 3M and Hilti Corporation.

Specifically, the 3M devices entitled: 3M Fire Barrier Cast-In Devices and Hilti Corporation devices entitled: Cast-In Firestop devices have been sold for use over metal decks. However, these devices and the others have many problems of their own.

For example, the 3M devices and Hilti Corp. devices require many installation steps that are both time consuming and costly in labor to install their devices, as well as many accessory items. In high rises having thousands of openings, the costs for these multiple installation steps can add extra labor costs and time delays that seriously affect these large building projects.
2 Atty Dkt.:

Furthermore, these devices require extra setup and finish time that include extra steps for cleaning and cutting that add additional labor and time delay costs.
The multitude of installation steps increases the chances for mistakes in the installation process. Again, buildings having thousands of openings that need to be sealed with devices that require a multiple amount of installation and assembly steps increases the chances for mistakes in installing these devices in many of the floor openings. Many of these devices also when installed do not fully waterproof the entire floor openings on the inside and outside.

In addition to all of these extra steps, the individual products that are needed come in separate packages and the contractor must carry them all over the project and figure out where they all go.

Still furthermore, the 3M and Hilti devices require large amounts of materials to be used since the devices come in many parts that must be assembled together and installed. The costs multiply with multi-story buildings and condominiums having thousands or more of floor openings that need to be sealed.

Still furthermore, none of these devices is an effective complete seal against water leaks, fire and smoke passage in concrete floors having corrugated decks since the concrete shrinks, over time leaving a path for water and smoke at the intersection of the sleeve and the concrete. None of these techniques and devices described above solves all the problems addressed above.

Thus, the need exists for solutions to the above problems with the prior art.

The subject invention is an improvement over U.S. Patent 6,792,726 to Price, the same inventor as that of the subject invention. The Price '726 patent is directed to a sealing system through concrete poured floors, and has been substantially modified and improved to be used with corrugated deck surfaces as described in the subject invention.

Fig. 1 is a cross-sectional view of a corrugated deck assembly embodiment 1 installed in a corrugated deck 10 that is sealed in place by having a poured concrete floor slab that is poured afterward. The sleeve assembly 1 can include the mid-body seal 300, with top sleeve extension extending upward from a middle of the mid-body seal 300, which is interconnected to the deck wing base 400, and fire stop material 600 clipped and attached thereto by fire ring 500. The left wing 410 and right wing 420 of the deck wing base 400 overlays the raised surfaces 12 of the corrugated deck 10 on both sides of the deck wing base 400. The wings 410, 420 have a long enough length of approximately 14 inches end to end to overlay the length of the lower surface valleys 14 of the corrugated deck 10. Each deck wing 410, 420 has a length longer than the width of the lower surface valleys 14.

When assembled a pipe 50 can fit within the central opening of the corrugated sleeve assembly 1 where an inwardly protruding rounded edge 345 of mid-body seal 300 tightly seals against the outside walls of the pipe 50. The pipe 50 can be any type of pass through pipe that passes through a floor such as but not limited to plumbing pipes, electrical pipes and conduits for power and communication lines, and the like.
Pipe 50 can be a PVC pipe, ABS plastic pipes, and/or metal pipes, such as but not limited to those formed from steel, galvanized steel, copper, and the like.

Fig. 2 is an exploded perspective side view of the corrugated deck assembly of Fig. 1, with top cap for protection during concrete pours 100 separated from the top sleeve extension 200, the deck wing base 400, fire stop material 600 and fire ring 500.

The mid-body seal 300 is a resilient flexible sealing sleeve that can be formed from rubber, elastomer, similar compositions, and the like.
Mid-body Atty Dkt.:

seal 300 can include an upper open cylindrical end 310, lower open cylindrical end 320, and an inwardly protruding seal ring 340 formed therebetween. The seal ring 340 can have an upper ledge surface 342 with rounded inner edge 345 on seal ring 340, and a lower ledge surface 348. Mid-body seal 300 includes an outwardly extending Mid-Body Seal Ring 350 with upper raised ridges and grooves for sealing and securing ring into the concrete 352 and lower raised ridges and grooves for sealing and securing ring into the concrete 358. A side cross-sectional view of the upper end 310, lower end 320, Mid-Body Seal Ring 350 and inwardly protruding seal ring 340 forms a generally t-shape. A
preferred embodiment can have three concentric rings of raised ridges and grooves on each of the upper and lower surfaces of the outwardly extending Mid-Body Seal ring 350.
Referring to Figures 1-3, 6 and 6A, the lower open cylindrical end 320 of the mid-body seal 300 is inserted around the upper small cylindrical ring 430 of the deck wing base 400 so that that the lower cylindrical end 320 fits tightly around and about the upper ring 430, and the top edge 432 of the upper ring can abut against the lower ledge surface 348 of the seal ring 340 in the mid-body seal 300. When concrete 40 is poured on the corrugated deck 10, the concrete locks around both sides of the Mid-Body Seal Ring 350 and fits around and into the upper raised ridges and grooves 352, and the lower raised ridges and grooves 358 forming a durable tight seal against water, liquids, smoke, gasses, and the like and also secures the device into the concrete. The upper raised ridges and grooves 352 can trap any water, fluid, and the like, that passes between the outside of upper open cylindrical end 310 and the poured concrete 40. The rounded inner edge 345 on seal ring 340 has a diameter that is sized to tightly rub against the outer walls of the pipe 50 that passes through the seal ring 340.

Atty Dkt.:

Fig. 7 is a top view of the deck wing base 400 of Figures 1-3 that can be formed from ABS plastic, and the like. Fig. 7A is a cross-sectional view of the deck wing base 400 of Fig. 7 along arrows 7A. Deck wing base 400 can include Left wing 410 having outwardly parallel strengthening ribs 412 and cross parallel strengthening ribs 418. Deck base 400 can also have a Right wing 420 having outwardly parallel strengthening ribs 422 and cross parallel strengthening ribs 428. Small through-holes 415 are used for securing the wings 410,420 to the surface 12 of the corrugated deck 410 with screws.

The strengthening ribs 412, 418, 422, 428 make the wings sturdy so that the wings 410, 420 will not bend up or down more than a few degrees, and will allow the one-piece sleeve assembly 1 to be secure and to effectively seal in place when the concrete 40 is poured on the corrugated deck 10 around the device.

Deck wing base can include a small diameter upper cylinder ring 430 with top edge 432 protruding upwardly from the wings 410, 420, and a large diameter lower cylinder ring 440 with lower bottom edge 448. A series of slot openings 450 allows for the upper ends 512 of the upwardly protruding prongs 510 of the fire ring clip 500 to pass therethrough and be bent back to hold the fire stop material 600 as is described below.
Referring to Figures 1-3, 7 and 7A, the wings 410, 420 of the deck wing base overlays the raised surfaces 12 of the corrugated deck 10 on both sides of the deck wing base 400 when the one-piece assembly is positioned over the opening 20 in the corrugated deck 10 so that the large diameter cylindrical ring 440 extends below the corrugated deck
10. The wings 410, 420 have a long enough length to overlay the length of the lower surface valleys 14 of the corrugated deck 10. Each deck wing 410, 420 has a length (approximately 14" end to end) longer than the width of the lower surface valleys 14.

The sturdiness of the deck wing base 400 allows for an effective seal with the corrugated deck 10 when the concrete 40 is poured in place.

Fig. 8 is a top view of the fire ring 500 without the fire stop material 600 used in Figures 1-2. Fig. 8A is a cross-sectional view of the fire ring 500 of Fig. 8 along arrows 8A. Fire ring 500 can be a clip type device metal formed from material such as but not limited to aluminum, galvanized metal, and the like. The fire stop material has been removed from Figures 8 and 8A in order to show the bottom base 530 and through-holes 535 in the fire ring 500. As described below and as shown in Fig. 1, the first stop material 600 is positioned to rest on the bottom base 530 of the fire ring 500. The fire stop material 600 can be an intumescence fire wrap that expands from the fire and heat to many times its size. With the heat expansion (intumescence), expansion can begin at approximately 41 OF(approximately 210C) with a significant expansion at approximately 555F(approximately 290C). Free expansion applies to approximately 25 times within approximately 5 minutes @ approximately 662F(approximately 350F).

Fire ring 500 can include upwardly protruding bendable outer prongs 510 with upper ends 512 and upwardly protruding inner tabs 520 with upper ends, and a bottom base 530 connects the bases of outer prongs 510 to base of the inner tabs 520.
Through-holes 535 are in the bottom base of the fire ring 530, the latter of which can support and hold the fire stop material 600 in place.

Referring to Figures 1-3, 7, 7A, 8 and 8A, the fire stop material 600 is positioned to rest on the bottom base of fire ring 530 between the inner tabs 520 and the outer prongs 510. Next, the upper ends 512 of the outer prongs 510 are inserted through the slot openings 450 of the deck base 400. The upper ends 512 of the prongs 510 are than bent outward as shown in Fig. I to attach the fire ring clip 500 to the deck base 400 and hold the fire stop material/wrap in a cylindrical orientation about the pass through pipe 50. As previously described, heat causes the fire stop material/wrap 600 to expand which will further cause a seal between the outer walls of pipe 50 and also help collapse the nonmetallic pipe when it starts to melt from the fire and heat, and fill the void around metallic pipe and the upper ring 430 of deck base 400 forming another seal against smoke and fire that could pass between the pipe 50 and the opening 20 in the corrugated deck floor 10.

Fig. 9 is a flowchart 900 of the three basic assembly steps for installing the no' cl one-piece sleeve into a corrugated floor deck. The steps can include determining the slab thickness of the concrete floor, Step 1(910), cutting an opening in the corrugated deck, Step 2(920), and the final step of installing the sleeve assembly 1, Step 3(930).

Fig. I OC is a top view of the corrugated deck wing base 460 of Figures 1OA-IOB. Fig. 1OD is an end cross-sectional view of the corrugated deck wing base 460 of Fig. I OC along arrow 100. Fig. IOE is a side cross-sectional view of the corrugated deck wing base 460 of Fig. I OC along arrow 10E.

Referring to Figures 1-1OE, another version of the corrugated deck wing base can be substituted for the deck wing base 400 previously described. Both deck wing bases 400, 460 have the similar components with the exception that deck wing base 460 includes extra strengthening ridges/ribs 470 running about the perimeter of the wings, and the crossed parallel raised ridges/ribs 480, 490 define rectangular sections that also can aid in further strengthening of the wings. Deck wing base 460 can be used with the installation method steps and sleeve assembly 1 that was previously described.

Table 1 shows comparisons of the installation steps between the invention (Pre sealed Systems) and a Prior Art system(Hilti system described in the background of the subject invention.) 1 "PVCdrain pipe Presealed Systems Hilti Minutes Additional Labor Step I Determine slab thickness 9-3/4" Step 1 Determine slab thickness Additional Material needed?

If each step costs one dollar. figuring a $60 per hour labor rate, (many steps cost more, such as cleaning the opening and cutting the device, which could require as much as five minutes) the Hilti device cost $23 and Presealed Systems, HydroflameTM deck device cost $17. The Hilti device is still not water proof on the outside.
In addition to all of these steps, the contractor must carry them all over the project and figure out where they go.

This also compares favorably to core drilling a hole in the finished floor for $50 and firestopping the opening for $15, after the installation of the pipe.
After the installation of the caulk, the W-Rating does not become effective until a full 28 day cure.
This comparison is true for all pipe sizes up to 1-1/2". 80% of all piping sold is 2" and below. So it figures that the above system is used a lot. If watertight is required by the specifications or by the owner it is an issue. If the contractor wants to provide water tight it is an issue. If everyone is trying to do everything as cheap as possible and as little as possible they will avoid providing a water seal.
