Abstract
A safety apparatus for building construction, and preferably for the above-ground construction of a home. The apparatus consists of at least two supports that are coupled directly to the building, either outside an above-ground floor and/or proximate the roof. The purpose of the apparatus is to provide fall protection for a person working on the roof or otherwise above-ground. The main components of the apparatus include at least two supports, planks extending between the supports to define a horizontal falling surface, and guard rails extending between the supports to define a vertical falling surface.
Description
- This invention relates generally to construction safety apparatuses and methods and, more particularly, to a safety platform that may be affixed to the frame of a building, such as a house, that is under construction.
- Persons engaged in certain activities related to the construction of a building, such as a home, face the risk of falling from their work area to the ground below. Particular danger areas include work on the roof and work on a second (or higher floor) where an exterior wall is not yet in place.
- It is desired to provide a safety apparatus and method that can provide fall protection to workers involved in above-ground tasks on a home or other building. The apparatus and method should be secure, and should be relatively easy to couple to the home (or other building) where construction is taking place. The apparatus should not require the assembly of a traditional scaffolding type of structure, which is generally positioned on the ground and which extends upward along one or more sides of a building.
- The present invention satisfies these needs and provides other, related, advantages.
- It is an object of the present invention to provide a safety apparatus and method that provides fall protection for workers involved in above-ground tasks on a home or other building.
- It is a further object of the present invention to provide a safety apparatus and method that provides fall protection and that is relatively easy to couple to the home or other building where construction is taking place.
- It is a further object of the present invention to provide a safety apparatus and method that provides fall protection and that is relatively easy to couple to the home or other building where construction is taking place, and that eliminates the need for a ground-based scaffolding type of structure.

- FIG. 11 is a side view illustrating yet another possible positioning of a safety apparatus consistent with the present invention, relative to a roof under construction and relative to the second floor of a building under construction.
- Referring first to FIGS. 1 and 2, an embodiment of a
safety apparatus 10 consistent with the present invention is shown. Thesafety apparatus 10 consists generally of at least two supports 12, at least one and preferably a plurality ofplanks 14, and at least one and preferably a plurality ofguard rails 16. - Referring additionally to FIGS. 3, 6 and9-11, the
supports 12 are now described in greater detail. Eachsupport 12 preferably consist of an upright 20 having at least one and preferably three guard rail supports 18 thereon, a plank support 15 coupled at a first end at a substantially right angle to the upright 20, and anattachment section 22 coupled at a second end of the plank support 15 and that permits attachment of thesupport 12 to thebuilding 100 that is under construction. As best shown by way of example in FIGS. 1-3, theplanks 14 are placed across the plank supports 15, and theguard rails 16 are secured by the guard rail supports 18. Preferably, strengtheningmembers 19 extend from theattachment section 22 to a point proximate where the plank support 15 and guard rail support 18 meet, in order to increase the strength of thesupport 12. - Referring now to FIGS. 4 and 5, attachment of the
attachment section 22 of thesupport 12 to the building 100 (see, e.g., FIG. 1) is described. Preferably, a plurality oflag screws 24 are inserted through openings (not shown) in theattachment section 22, and into one or more studs or posts on thebuilding 100. One and one-quarterinch lag screws 24 have been shown to be desirable for this purpose, thoughlag screws 24 of other lengths, or indeed other hardware such as bolts, could be utilized. - It is preferred to attach the
attachment section 22 to a place on thebuilding 100 where there are twostuds 26, three studs 26 (not shown), or a large post (also not shown). While coupling to asingle stud 26 may be possible, it is preferred for safety reasons to require at least the use of adouble stud 26, so as to guard against accidental detachment of theattachment section 22 in the event that aperson 200 falls onto theapparatus 10. Referring now to FIGS. 4 and 7-8, it is preferred that theattachment section 22 have a substantially L-shape, so that it may be coupled along a width and a thickness of thestuds 26. And, as shown for example in FIG. 1, onesupport 12 may be coupled at a corner of thebuilding 100, while another is coupled within a side of thebuilding 100. It may also be possible to provide twosupports 12 within a side of abuilding 100, or to have anapparatus 10 consisting of three (or even more)supports 12 coupled, as desired, along a side of abuilding 100. For example, where threesupports 12 are utilized, it may be desired to place asupport 12 at each end of one side (i.e, at the corners), and athird support 12 at substantially a midpoint therebetween. It is generally preferred that supports 12 be spaced no more than about 10 feet apart, so as to reduce the risk that planks 15 could break in the event that aperson 200 falls thereon. - In terms of materials and dimensions, it is preferred that the planks15 be 2×12's, and that the guard rails 16 be 2×4's. Other dimensions would also be possible, as desired. While the use of wood is preferred, plastic or metal materials could also be substituted.
- The
supports 12 are preferably formed from tubular steel. The upright 20 preferably has a length of about 44″, the plank support 15 preferably has a length of about 32″, the strengtheningmember 19 preferably has a length of about 44″, theguard rail supports 18 are dimensioned to be able to receive aguard rail 16 therein, and theattachment section 22 has a length of about 35″. These measurements are preferred, but even significant deviations are possible without departing from the spirit or scope of the present invention. It should be noted that it may be preferred to provide gussets (not shown) for purposes of further strengthening thesupports 12, proximate the attachment of the upright 20, plank support 15 and strengtheningmember 19 and/or proximate the attachment of the plank support 15 andattachment section 22. - Referring now to FIGS. 1 and 9-11, in one embodiment, the
apparatus 10 is coupled proximate theroof 110 of abuilding 100 that is under construction. As illustrated by way of comparison in FIGS. 9 and 10, the position of thesupport 12 relative to theroof 110 may be varied somewhat, so long as theapparatus 10 will prevent aperson 100 from falling past theapparatus 10 to the ground. Thus, as shown in FIG. 9, theapparatus 10 could be positioned relatively higher, so that theguard rails 16 will stop a fallingperson 100. As shown in FIGS. 1 and 10, theapparatus 10 could be positioned relatively lower, in a manner that might permit aperson 100 to fall to theplanks 14. An advantage of a relatively lower configuration is that it might permit the use of theapparatus 10 as a scaffold as well as a safety support. - Referring now to FIG. 11, it can be seen that the
apparatus 10 may be positioned proximate a second floor of abuilding 100. (Such placement could be instead of or in addition to the placement of asecond apparatus 10 proximate theroof 110.) When used in this manner, theapparatus 10 may particularly permit a dual use as a scaffolding and safety apparatus. - The
term building 100 is intended to capture the full range of edifices that may be constructed. In the preferred embodiment, thebuilding 100 is a home. However, thebuilding 100 may also be a commercial or other non-residential structure. - While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
