BARRIERS TO THE INVASION OF PESTS
FIELD OF THE INVENTION The present invention relates to physical barriers for pests and in particular, to physical barricades for pests and methods to prevent or reduce the invasion of pests to a building or structure in the area surrounding a penetration. of services. The present invention has particular application for coverage of the area surrounding a service penetration of concrete foundation slab for construction, which has a barrier for pests arranged intermediate to the underside of the concrete foundation slab and the floor below the slab, invention also has application for the coverage of area around a penetration of services, previous casting of the concrete foundation, basement, or slab of space for tracking. BACKGROUND OF THE INVENTION Various measures have been proposed to prevent pests such as termites, homigas, and other pesky insects from entering buildings or other structures in particular residences and commercial accommodations. One method is the use of a chemical pesticide repellent to create a chemical entry barrier or for the survival of the pest in an exclusion zone. Another method is to create

Stdies have been carried out to observe the minimum spaces in which creeping pests are introduced, Specifically, some studies on termites suggest that a space around jL / 20 inch (1.27 mm) is sufficient to prevent access by termites (Ewart D. McG., M. Tamashiro, JK Grace &R H. Ebesu, 1991, "Minimun foraging aperture and particle barriers for excluding the Formosan subterranean termite", pnpublished Poster, Ann. Meet. Entomol. Soc. America, Reno, Nevada). This space is specific to the species, and for small termite species, an even smaller space may be sufficient for the entrance of the termites) Regardless of the size required for the entrance, a significantly reduced space around the penetrations will reduce the chances of pect ation of termites. In this way, there exists the necessity of an improved barrier or device to prevent the incursions of pests into common points such in 1 standard construction. Brief Description of the Invention The present invention provides a solution to the problem of creating an e ective barrier to the invasion of pests, around service penetrations in foundations, foundation dies or walls of buildings and other structures. The invention provides means for creating a barrier around an elongated member of a cover being installed. The | flange is adapted to directly contact surfaces such as a concrete slab or a contiguous plastic sheet, to further improve the seal degree of the cover when the cover is installed in a service infeed. An installed configuration is reached by opening an individual folded flat roof placed along a penetration of services in the foundation, given the foundation or wall of a building or other structure, by moving it telescopically in a downward direction on the penetration of services and cutting the closed end to create a sufficient opening will give the passage of an elongated member of the penetration of servKcios, and adapt to a temporary friction retention jiurito with the penetration of services until the cover s secures and seals in addition around penetration The circumferential flange portion of the cover is then sealed to a foundation surface, given foundation, wall, cover sheet or vapor barrier through which the service ptrussion occurs, Alternatively, the cover is It is placed along a service penetration as observed prior to the casting of the concretol foundation slab, and in such a way that the circumferential flange is placed intermediate to the underside of the concrete slab and the surface of the slab after the foundation is emptied.

In one embodiment, the barrier cover is impregnated with a pesticide such as an insecticide and / or fungicide, optionally in a controlled release form such as a programmed release or a non-release form substantially (unless the integrity of the pesticide is compromised). the cover) . The present invention also provides another solution to the problem of creating an effective barrier to the invasion of pests around penetration. services in foundations, foundation foundations or walls, buildings and other structures prior to the emptying of a concrete foundation. This aspect of the invention provides means for creating a barrier around a prolonged member of a service penetration eg a pipe, and the formation of a continuous barrier within the concrete surface. The devices of the present invention when installed, avoid the formation of important aspaces between the device and a penetration of services and between the device and the concrete layer. If some spaces are formed, they are small enough that the path of the creeping plague it is deviated or leached significantly and ideally is completely inhibited. Specifically for termites, there should not be continuous spaces across the barrier or greater than 1/16 inch (0.159 cm) and even more preferably 1/32 in. (0.79 cm).

Figure 10A shows an upper view of the sleeve portion which is combined in small part in Figure 10, forming the detailed embodiment in Figure 12. Figure 11 shows a top view of one embodiment of the invention in FIG. where the portion < f of disks is opened to receive the sleeve portion detailed in Figure 11A.
In another aspect, the invention relates to a barrier cover having a conical body with a closed end formed by the apex of the conical body; and an open "bottom" end adapted to come into close contact with a surface when installed. The conical body is flared from the open end of the bottom toward the closed end so that the closed end can be cut to create an "upper opening for the passage of an elongate member inserted through the barrier". When installed, in addition to close contact, the friction fit achieved by the invention around the penetration of services, can be secured and / or sealed around the penetration, top or first opening of the barrier cover. The upper part and the first opening of the barrier can be secured when tying, closing with tape, the use of a draft joint or a twist joint, and / or a sealant or filler. The sealer or filler may include a repellent for pests or pesticides. The second or bottom opening is the barrier cover of the invention, it may include a circumferential flange having a first face positioned towards the top or first opening of the tubular portion (or the conical apex) and a second face positioned towards the floor or the surface to contact. The circumferential flange may be placed at an angle relative to a longitudinal axis of the tubular portion and / or substantially parallel to the surface to be contacted by the second face when the cover is installed. The flange can be adapted to be raised to the surface by a heat sealed processAlternatively, or in addition to heat sealing, the second face of the circumferential flange 1 can be secured and / or sealed to the surface with an adhesive. The adhesive may include a pesticide or a repellent of pests. The heat seal and / or adhesive can advantageously be used when the barrier cover of the invention is bonded to a sheet-like plate barrier such as a woven or non-woven textile sheet, a continuous plastic sheet or other polymeric sheet 1 or a Stainless Steel Sheet. The type 1amine barrier can be produced specifically as a barrier to chemical / physical or physical pests. Alternatively, theThe invention can be sealed to a surface such as a concrete slab of a foundation of a building, by instilling the barrier so that the second opening and / or circumferential flange is lodged in the concrete slab. The barrier cover is adapted for use with elongated members such as penetrations for multi-size constructions and service facilities. Such elongated members include but are not limited to, plumbing and service supply pipes, 12
gas lines, electrical wiring) and conduits. Such parts can generally be referred to as service penetrations, and often enter a structure through a foundation or foundation deed. n. An opening of the barrier cover, is designed to contact a surface of a physical / chemical barrier that has been punctured by the penetration of services, A suitable surface includes a cover sheet of horizontal reconstruction designed to create a continuous protective barrier in an excavation area formed after the digging work, intended for the construction of a foundation and / or die of a structure, The continuity of this surface can be compromised by the necessary penetrations of services (water , gas, electricity) and exit pipelines. The barriers of the invention facilitate the restoration of a conti- nuous barrier in areas such as service penetrations. The resturation of the continuity of the cover sheet is achieved in the area of penetration by a closed fit a continuously sealed barrier cover of the invention. In some installation situations, it may not be practical or desirable to pull the conical shape over the penetration. In these situations, a vertical slot can be made in the cover, after a top opening has been created to allow the cover to be pulled or metal (such as stainless steel or aluminum). In the form of a sheet, the material must be sufficiently flexible to allow a fastening means to conform to the service penetration contours at one end and a surface from another barrier, wall or floor at the other end. The polymeric material that forms the barrier cover can be obtained by the extrusion of polymers, particularly polyolefins, such as polyethylene or polypropylene or polyvinyl chloride and analogous copolymers, the thickness of which is between 0.5 thousandths (0.0127 mm) and 50 thousandths (1.27 mm). A pesticide can be incorporated into the polymeric material during the extrusion of the polymer film, the ratio being a function of the effectiveness or the active ingredient used. The production of the polymer film can be carried out by Lenao of the polymeric material by blowing, hot extrusion! or by extrusion, it being possible for any of these extrusion methods to be followed optionally, by hot pressing and analogous processes known to the person skilled in the art. As you can see the cover of! barrier of the invention, it can also be produced as a material having a repellent for pests or pesticides) incorporated therein. This material can be a polymeric (polymeric) matrix and a repellent or pesticide, which results in a controlled release that includes a programmed release or a 16
minimal releasing release) with at least one plaque retaining the pesticide as described in WO 02/43487 A2. In one embodiment, the above-mentioned primer layer 1 comprises an encapsulated pesticide plaque such as an insecticide or a fungicide. For example, the micro encapsulated pesticide can be any of the micro-encapsulated material as described in the U.S. Patents. ??and,
5,639,710; 5,725,869; 6,133,197; or 1, 149, 843. The barrier cover also includes additional layers to protect the barrier from environmental factors such as ultraviolet rays. These additional protective layers are generally included as the outermost layers of the barrier cover. Also, these protective layers can be made of polymers that are: sealed with heat to facilitate the heat sealing capacity of the barrier. The thickness of these protective layers can generally be in the range of 0.0005 inches (0.012 '7 mm) to about 0.003 inches (0.0762 mm), preferably around 0.001 inches (0.0254 mm). The walls of the barrier cover are held together or bonded to one another to form a multilayer unit product. The layers can be linked to each other directly, or by using d = tie layers. The retention layers are preferably made of a polymeric material, for example, SíRANEX, marketed by the Dow Chemical Company, Midland, Mich. The retention layers generally have thicknesses in the range of about 0.001 inches (0.025 mm), up to about 0.005 inches (0.127 ram), preferably around 0.002 inches (0.0508 rom) When the retaining layer is intact more than a release layer, it controls the liq eration of the barrier cover pesticide when the retention layers However, an effective amount of the repellent or pesticide is available to prevent the invasion of the pests through the hole or tear. The longevity of the barrier cover, after a break has occurred, can be increased by the use of a release layer which is a controlled composition of slow release and programmed release.The release layer can be made from a polymeric matrix and a pesticide that is dispersed through the matrix, or by a microencapsulated pesticide. In one embodiment of the present invention, the polymer matrix is made of low density polyethylene (io) In another embodiment, the microcapsules contain suspensions of biologically active compounds and a protect <; ultraviolet. The term "pesticide" as used herein, includes insecticides and fungicides and any bioactive chemical that repels and / or ewitates that the pests make contact with or penetrate the barrier cover. The classes of active ingredients for use include pyrethroids, penetrations, therefore the following description will use the term "conduit" to include all penetrations housed in concrete. Ducts can enter | in concrete at a variety of angles, so ducts can be extended vertically through a concrete slab, however, they can also come in concrete foundation dies horizontally. Ducts may not necessarily be at right angles to the plane of the concrete, and thus the pipes may enter concrete structures at a variety of angles. It should also be recognized that flexible conduits may not pass in a straight line through a concrete structure and may be curved. The invention described herein will help protect all conduits passing through a concrete structure. In one aspect, the device is designed in such a way that it can be installed in pipe configurations known as bath traps, where a region surrounding a pipe is blocked from the flow of concrete during the pouring of the concrete slab, by means of some continuous vertical barrier placed around the t bo such as an open cardboard box. The purpose of this configuration is to allow space for the future installation of pipes, necessary to be coupled with the bath tub or shower whose position is not known with precision at the time of concrete casting. The concrete region can not be left filled, filled with soil or then filled with concrete. The device is designed to accommodate vertical barriers of different shapes and sizes in situations where the hollow of the baby trap is left open or is then filled with soil or concrete. The device consists of a barrier cover having a tubular portion with a first opening adapted to make contact closely with an elongated member passing through the tubular portion when the barrier is installed. The upper part or first opening of the barrier cover, can also be secured and / or sealed around the penetration, when fastening, sealing with tape, the use of a draft connection or twist union and / or a filling os hilador. The tape, filler or sealant may include a repellent of pests or pesticides. A second opening] placed at the opposite end of the tubular portion is adapted to closely cope with a horizontal component of a barrier material by means of a circumferential flange which can be sealed to the surface by a seal process with heat Alternatively, or in addition to the heat seal, the second face of the circumferential flange can be secured and / or sealed to the surface with the tape, adhesive, filler or sealant. The tape, adhesive, filler or sealant may include a pesticide or ur plague repellent. The horizontal component of the device consists of a section of flexible barrier film, which has an upward turn on its periphery, supported by a reinforcement material that can be housed in the concrete during the emptying of the concrete slab. The reinforcement material can be any material that stiffens the outer edge including plastic materials (polystyrene, polyester, polyethylene, PVC and many others) or (metals (stainless steel, aluminum as examples) and can be placed to the flexible barrier by various methods included but not limited to adhesives, heat seams, acid, rivets, sonic welding and snaps The horizontal component contains a hole through which the perietration to be treated can pass. anywhere on the sheet, provided that the installation of the barrier cover and the application of the concrete barrier, allow a space of at least 1/4 inch (0.635 cm) or more preferably 1 inch (2.54 cm), between any barrier concrete that can be installed and vertical upturn in the device, in which the concrete can flow. The horizontal component may be of any shape but is preferred in circular, square or rectangular forms. The size for a circular shape can be from a diameter of 1 foot to 8 feet (0.30 to 2.43 m), more preferably 3 feet (1 meter). A piece of form The means to deflect the pjlagas ideally result in a complete outer edge of the deviation, which is housed in the concrete to form an integral seal with the concrete slab. The degree of accommodation may vary depending on the type of duct or installation. The outer edge can typically be accommodated by 1 / | 8 inch (0.125 mm) up to 8 inches (20.32 cm) to ensure a good seal; preferably by ¾ inch (1.27 cm) to 2 inches (5.08 cm) and more preferably by approximately 1 inch (2.54 cm). In one form, the barrier device resembles a section of a circular crown as shown in Figure 7, which can be formed into a conical shape, with a first opening, smaller, adapted to closely contact an elongated member passing through the center of the cone, a second larger opening, located at the opposite end of the circular crown sector, is adapted to be housed in the concrete. To assist this housing, the second opening can be widened or inverted to form a well in the form of a thread in the material, as shown in Figure 8. The width of the well can vary according to the necessary inscription characteristics. . However, in order for the product to optimally perform the distance from the outer end of the closed plastic duct, it must be such that the concrete can flow. The total height of the installed device may vary depending on the size of the duct or to be protected and the additional use of the device as a protection for the duct above the surface of the concrete. As a result, the deposit mode can be fully accommodated within the concrete; or it can be installed in such a way that there is a plastic malnga around the duct above the level of the oncrete. Therefore, the total height of the installed device can be from 1 inch to 10 inches (2.54 cni to 25.4 cm). For a device to be installed in the conch from 1 inch to 3 inches (2.54 cm to 7. 62 cm) and preferably 2 inches to 3 inches (5. 08 cm to 7. 62 cm). For a design that is intended to be present throughout the full depth of the concrete, the design can be from 3 inches to 8 inches (7. 62 c up to 20.32 cm) or greater, depending on the thickness of the concrete. The barrier device of the present invention can be a pre-formed flexible sheet 2 (Figure 7A), which is formed in a conical shape in situ around the conduit; or as a previously formed dominate device ready to slide over the conduit and join in the manner described above. The flexible sheet would have a method for adhesion along the long recess end, which allows the formation of the device in the field. This method of 35
It can serve as either the fastener that secures the sleeve to the tube at the end or acts to temporarily hold the sleeve in place until a permanent fastening system is placed. When installing, in addition to 1 close contact, the friction adjustment achieved by the barrier around the penetration of services, the upper part or first opening of the sweeping device can also be secured and / or sealed around the penetration. The top or first opening of the barrier can be secured by binding, taping, the use of fasteners or threaded fasteners, Velero® and / or a filler or sealant. The tape, filler or sealant may include a pest or pesticide repellent. The barrier device may be adapted for use with conduits such as penetrations of multiple-sized constructions and service penetration. Such service penetrations include, but are not limited to, plumbing and plumbing that provide services, gas lines, electrical wiring, and conduits. Such points can generally be referred to as service penetrations and frequently enter a structure through a foundation or foundations. As discussed above, the barrier devices of the invention may include at least one polymeric material. The polymeric material includes at least one pesticide or a pest repellent as an active ingredient.
36
Alternatively, the flexible barrier device can be made of any suitable material including a woven or nonwoven fabric or a polymeric material, or a metallic material (such as stainless steel or aluminum). In a sheet form, the material should be sufficiently flexible to allow it to be conformed by a fastening means to give rise to the penetration of auxiliary services at one end, and to lodge in the concrete structure at the other end. polymer forming the barrier device can be obtained by the extrusion of polymers, particularly olefins, such as polyethylene or polypropylene or ivinyl chloride and analogous (co) polymers, the thickness of which is between 0.5 mil
(0.0127 mm) and 50 thousandths (1.27 njrcn). A pesticide may be incorporated into the polymeric material during the extrusion of the polymer film, the ratio being a function of the effectiveness or the active ingredient used. The production of the polymer film can be carried out by starting the polymer material by hot extrusion blowing or extrusion; or optionally, by hot pressing and analogous processes known to a person skilled in the art. The advantage of using a flexible barrier material, which gives advantages in the installation way that allows the devices to be manipulated to adapt a multitude of sizes and materials. Frequently the flexible materials 37
they undergo an attack by crawling pests, particularly termites, and in this way the co-ordination of a flexible material in these designs together with a repellent pesticide, is of particular benefit. In another embodiment of this invention, the devices described above can be prepared using a polymer mixed with an insecticidal material that is prepared using a manufacturing technique that melts the polymers together and incorporates the insecticide in a single step. Such a technique may be the use of injection molding. Referring now to the figures, Figure 1 shows a modality of a substantially conical barrier cover 2 placed in a service entrance 8 for a building under construction. The perietration of services 8 emerges through the floor 18 and a barrier of termite protective sheet 16 which is placed over the foundation area before emptying a concrete foundation slab. The barrier cover 2 has an opening 6 and gradually extends towards the apex 4. The opening 6 of the barrier cover 2 is circumscribed by the flange 10 having a first face 12 and a second face 14. In one embodiment, the opening 6 has a width from | 4 to 12 inches (10.16 to 30.48 cm). The second face 1 is adapted to closely contact the barrier 16 when the installation of the barrier cover 2 is completed around the penetration 39
of the building. Since termites can build terrestrial tunnels up to the crossbars and other wood used in the structure through these points of entry, these entry points are critical sites that require protection. Figure 3 shows a cross-sectional view of the barrier 2 of Figure 1. The Figure shows an alternative mode of the barrier of the ion: ion. The truncated cone 30 is similar to the barrier 2 of 1 s Figures 1 and 2, except that the opening 32 is provided in predetermined diameters to provide ur. closed contact with the penetrations of commonly used services. Figure 5 shows the multiple layer substructure of a barrier modality. See Example 2 below, Figure 6 shows the barrier cover having a tubular portion with a first opening 80 adapted to closely contact the conduit 1 passing through the tubular portion when the sweeper is installed. The top or first opening of the barrier cover can be secured by a draft tie or thread tie 82 as shown in Figure 6A A second opening, disposed at the opposite end of the tubular portion, is adapted to contact a horizontal component of the barrier material by means of a circumferential flange which can be sealed to the surface by a
heat sealing process. The horizontal component of the device consists of a section of flexible barrier film having on its periphery an upturned part, supported by a reinforcing material 84 as shown in Figure 6B. The horizontal component with reinforcement material allows the device to lodge in the concrete during the emptying of the | concrete slab. Figure 7 shows a section through a circular crown representing the flexible sheet modality of the invention. Figure 7A shows a front view of the flexible sheet embodiment of the invention prior to installation around a peel; ration of services. The flexible sheet has a method of adhesion 90 along the long straight end, allowing the formation of the device in the field; and an additional stiffening mat 91 attached to the end of the second opening to add additional stiffness once the positive day is formed, FIG. 8 shows a side view of an embodiment of the invention installed around an inset services. The upper end of the sleeve portion is joined using a 10 | 0 cable tie, and to assist with the particular housing, the second opening is inverted and widened to form a screw-shaped well 101 of the material. Figure 8A shows the device housed in concrete, in such a way that the outermost extremity of the 42

The upper part of the first opening of the disk sweeping device is secured around the penetration using a cable knot 140. Optionally, the lower sleeve is secured in the same way. The disk portion of the device has an optional reinforcing disk structure 141 laminated within the disk portion to impart increased rigidity to the disk. Figure 12A shows a cross-sectional view of the device or the figure covered with concrete. Figure 13 shows a close-up view of Figure 12, where the device is covered with concrete, so that if they were to form different spaces 150, there were no spaces between the barrier and the conduit more than 1/16 inch | l.59 mm) EXAMPLES The following examples are provided as illustrative embodiments of the invention, and are not intended to limit the scope of the invention in any way.

Example 1 Installation of the conical stroke cut to fit A barrier having initially a simple opening bordered by a pin, adapted by a barrier in layers to be sealed by heat, is used. The body of the barrier is formed from a mat < This material includes an active layer of a polymer matrix and a lambda-cyhalothrin type pesticide dispersed through the matrix and a binder such as carbon black. The active layer is sandwiched between the two SARANEX layers (The Dow Chemical Company, Midland, MI). This arrangement prevents any substantial loss of lambda-cyhalothrin until the outer SARANEX fractures. The pesticide is available in an effective amount in the area of the fracture such that the entry of the pests via the fracture is prevented. Prior to the installation of the barrier, the construction site is prepared for the installation of a foundation and a penetration of services in the place. Next, a layered barrier is installed in the total area, which includes service penetrations, using transverse incisions in the barrier at < rapas. The conical barrier is placed on the upper end of an elongated member] of service penetration, such as a tube. The end of the tube is inserted through the opening and the conical body is placed on it includes a layer of polyethylene pe high density, woven (canvas) to provide additional strength and durability. The outermost layers are selected to provide protection from deterioration due to exposure to UV rays and to provide improved heat sealing capacity. As illustrated in Figure 5, the material is produced as an eight layer product as follows: Layer 1- layer 60 of New Generation Resin (NGR) (Fabrene, Inc.), composed of black resin (No. 20413- 19, Colortech Inc.), plastomer tie polyolefin grade extrusion coating (Affinit r PT1450, Dow Plastics), and low density polyethylene (LC-0552-A, Nova Chemical Co., Calgary, Alberta, Canada), which it has a thickness of approximately 0.001 inches (0.0.54 mm); Layer 2- layer 62 SARANEX® 14 (Dow Chemical Company), composed of a copolymer of vinylidene chloride / vinyl chloride, low density polyethylene, vinyl ethylene acetate copolymer and silicon dioxide, having a thickness of approximately 0.002 inches (0.0508 mm); Layer 3- layer 64 NGR, as described above; Layer 4- layer 66 of canvas (Fabrene Inc.), Composed of high density polyethylene (Se [Lair HDPE No. 99G, Nova Chemical Co.) and black resin (PlasbtLack PE1371, Cabot Corp.), which has a thickness of approximately < 0.004 inches (0.1016 mm).

The conical barrier slides along the pipe in the direction of the ground, until the | The bottom of the device comes in contact with the ground. The cone is then tied twice to the top of the cone once near the base of the cone Example 4. Preparation of a jiisk, to fix a tube of ¾ inch (19 mm). The flexible described in Example 3, with an external diameter of 2,915 inches (74 mm) (Figure 10) is placed on a short segment of metal tube of exterior diameter similar to a copper tube of ¾ inch (0.875 inches-22.2 mm). ) sliding the tube through pre-cut grooves in the center of the disc.The grooves extend radially from the center, with a radius of approximately 0.437 inches (11.1 mm), or half the outer diameter of the copper tube. The disc is pulled down the tube until the ends of the triangular spacer pieces of the center cut are matched to the end of the tube.The sleeve is 3 | 25 inches (8.26 cm) in length and 1.25 inches (3.18 cm) in width ( figure 10A) was covered once around the pi The triangular separators were fastened in the place with a short section of plastic tube with a larger diameter than the metal tube, which has a groove that closes below its length. The excess material of the sleeve that comes out of the groove prevents the sealing of the rest of the sleeve, creating an opening. The sleeve was joined to the spacer pieces by heating the pipe by a torch or by using an ultrasonic welder, forming a "top cover" type. The tube and the plastic tube retainer were removed. A polystyrene reinforcement disc with an external diameter of 2,915 inches (74 mm) and an internal diameter of 0.915 inches (23 mm) were coated on one side with a strip of double-sided adhesive tape! and pressed into the lower portion of the upper lid portion, after removing the backing paper, keeping the hole aligned with the lid portion a | lta. A slot was cut inside the part of the disc from top to top which extends radially from the center line to the outer circle and in line with the left sleeve aperture. This was repeated for another portion of the top cover except that, To the reinforcement disc was applied a strip of double-surface adhesive tape applied on both sides. The high lid portions were joined first, removing all the backing paper from this high lid portion except for a small sector with an external arc length of about one inch (2.54 was), which extends to 54

The disk device was wrapped around a 3/4"(1.9 cm) copper tube, and the disc portion adhered when the stretched disc was pulled and pressed into the overlap region to adhere to them. They are pulled up, stretched, wrapped around the tube and adhered in. A cable tie is installed around the top sleeve and one is installed around the bottom sleeve and secured securely Any prbtector material around the tube that is removed, is replaced on the top of the device, Example 7: Installation of an inverted cube from a flat sheet The penetration of services is prepared by repositioning or temporarily removing any protective material that covers the pipe, so that the device: can be installed on or near the floor surface, allowing intimate contact between the conjunct device and the tube STEP 1: The correct size device is selected to fit the size of the device. the penetration of services to be treated.

The opposite edge of the cone is aligned and the two edges adhere with an overlap of ¾ inch (1.27 cm), keeping the sel or around the bottom as airtight as possible, forming a sleeve portion of the device. A uniform adhesive seal is used to ensure a tight seam. The overlapping edges of the reinforcement material (Figure 7A) are held together for additional strength using staples or other fastening devices / materials. The device slides under the penetration of services, so that the lower portion of the device sits on or just above the floor surface. STAGE 3: The inverted cone is held in one position using two plcistic cable joints as a cable attachment clamping unit. Once the device is in position, a wire joint is installed in the lower portion of the inverted cone and another 1 inch (2.54 cm) below the ring insert. It formed the inverted cone as shown in Figure 9. The two cable joints are arranged around the device, so that the closing mechanisms of the cable joints are on the opposite sides of the cable penetration. tube. A third cable joint can be placed between the upper and lower joints to prevent bunching of the sleeve portion.
