With reference to FIG. 1 shown is a perspective view of one embodiment of the netting system 10 installed on an exemplary working deck 20. In some embodiments, the working deck 20 is a construction zone or area upon which concrete or other building material is laid in order to create a deck, floor, or other surface. The system 10 comprises array or a plurality of spaced apart vertically disposed retention brackets 30 disposed at least partially around the perimeter or other desired location of the working deck 20 so as to form an array of attachment points for one or more debris-retaining liners or nets 40 to be attached to and disposed between the brackets 30. The brackets 30 extend vertically upward from working deck 20 such that the nets 40 are positioned substantially perpendicular to the surface of the working deck 20 in order to collect or retain debris such as concrete or paint overspray that may be carried away from the working deck 20 during construction.

With reference to FIGS. 2-3, shown is one embodiment of the bracket 30 of the system 10. In some embodiments, the bracket 30 comprises a clamp base 31 and a pole 32 extending vertically from the clamp base 31. The clamp base 31 is configured to be secured to the working deck 20 and includes a fixed base member 311 with an optional adjustable clamp member 312 that permits the clamp base 31 to be secured to the working deck 20 by tightening or closing the clamp member 312 with respect to the fixed base member 311. Adjustable bolts 313 may be provided through the clamp member 312 to secure the clamp base 31 to a joint 21 and/or stringer 22 of the deck 20. The clamp base 31 is configured to be adapted to be secured to a variety of decking and floor surface configurations and has alternative securement features to accommodate bolts and fasteners.

The pole 32 extends upward from the clamp base 31 and provides a plurality of points of attachment for the one or more nets 40. In some embodiments, attached to the pole 32 are one or more pulley systems such as inner pulley system 41 and outer pulley system 41′. Each pulley system 41 and 41′ comprises an upper pulley 411 and a lower pulley 412 vertically spaced apart along the length of said pole 32, with a cable 413 at least partially wrapped around and the upper and lower pulleys and thereby connecting the two pulleys. In some embodiments, the inner and outer pulley systems 41 and 41′ are spaced apart or offset from one another in order for the pole 32 to accommodate a plurality of nets 40. One or more nets 40 are provided, attached at a lateral edge 401 thereof to the cables 413 of the respective pulley systems 41 and 41′. Attachment may be accomplished by eyelets in the net or other fasteners such as clamps, clips, snaps, or the like. This allows the nets 40 to be translatable or height adjustable along the length of at least a portion of each pole 32 and further allows the nets 40 to be held taught. In some embodiments, two nets 40 are attached to a pole 32, with a first net attached to 40 attached to a first pulley system 41 and a second net 40′ attached to a second pulley system 41′.

In some embodiments, the bottom edge 402 of each net 40 should be secured at or adjacent to the deck 20 in order to avoid any gaps at the bottom thereof that could allow for the passage of debris. In some embodiments, wood planks or other weighted members are placed over and about the bottom edge 402 of each net 40 in order to removably retain the net 40. In some embodiments, eyelets, clamps, clasps or similar retaining and fasteners may be employed to attach at least a portion of the bottom edge 402 of each net 40 to the working deck 20.

The netting system 10 is configured to be modular to adapt to various sized and shape working decks and working areas. In some embodiments, a plurality of poles 32 are provided with at least one net 40 disposed between and retained by adjacent poles 32. For example, three poles 32 can be provided in a spaced apart relation, with two nets 40 provided, each net attached at their outer lateral edges 401 to the outer poles 32 and at the inner lateral edges 401 both to the central pole 32. The pulley systems can be selectively engaged as needed, for example in this configuration only one pulley system is provisioned on the outer poles 32 but both pulley systems 41 and 41′ are provisioned on the central pole 32, each pulley system 41 and 41′ assigned to retain a respective net 40. Additional poles 32 and nets 40 can be provided in sequential fashion as needed to cover a desired area.

It is appreciated and understood that the various system 10 components may comprise materials of varying material and cross-section. For example, wood, steel, aluminum, and combinations thereof may be employed for the poles 32 and attendant hardware. Cross-sections may vary as the poles 32 may be tubular, square, or L-shaped. The means and manner by which the poles 32 are secured to the working deck is not limiting although in some embodiments a clamp member 312 may be employed. Other hardware may be utilized to reinforce the attachment points on the slab such as bolts and other permanent or removable fasteners. The net 40 can vary in type, thickness and designed although it may desirable to employ a net 40 with a fine mesh backing or fine mesh array in order to retain and prevent the dispersion of debris, especially that occurring during stucco, tile, and concrete application. The means of attaching the nets 40 to the cables 413 of the pulley systems 41 and 41′ of the brackets can vary but may include hooks, clips, eyelets, and other like fasteners or securements.

By way of non-limiting example, it is helpful to describe certain relative dimensions of system components. In some embodiments, it is desirable for each of the poles 32 to extend upward to a maximum height of 12 feet in order to provide optimal coverage and retention of debris during material application to the working deck. The spacing of the poles 32 may also vary although in one embodiment it is desirable that the brackets are spaced apart no greater than 15 feet in order to accommodate nets 40 or reasonable size and workability.

The system 10 of the present invention is designed to be installed and secured to a working deck in order to provide a substantially vertical protective barrier or wall that can catch and retain construction debris. In some embodiments, the system 10 is located downwind of a weather-exposed working deck such that the nets 40 have the best opportunity to catch, retain, and prevent the spread of construction debris. The system 10 can adapted to be installed in a modular fashion in varying size, shape, dimensions and orientations as the angle between adjacent nets can be adjusted by adjusting the relative location of the poles 32. This allows the system 10 to confirm to the size, shape, dimensions, and other requirements of the working deck or space where debris containment is desired. The system 10 is also designed to be modular in order to permit its usage in a variety of applications and with various sized, shaped, and configured working decks and can even be configured to entirely encircle or encompass a working deck, or otherwise only partially so. The system 10 may can be employed in a variety of building applications including high rise construction, low rise construction, bridge construction, and the like.

While specific embodiments have been described in detail, those with ordinary skill in the art will appreciate that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosures. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting of the invention, which is to be given the full breadth of the appended claims, and any and all equivalents thereof.
