Abstract
A system and method of fastening a railing member against an anchored horizontal rim beam of a deck, stairway or balcony. The system typically includes a series of upright railing members in combination with a plurality of securing members. The securing member can be a clench bolt, a clench strap (formed or welded), or clench brackets. The securing member is able to secure and/or fasten the railing member and the rim beam together without creating holes in the substance of the rim beam or other deck material, so that rotting, splintering or other type of erosion of the deck material over time is minimized. The railing attachment system and method can be used on wood, fiber, synthetic, steel or concrete decks, for either newly constructed or repair of pre-existing decks, balconies or stairways.
Description
- The present invention relates generally to railings and barriers used to separate environmental areas, and more particularly to a system and method for installing railing members in residential and commercial decks, staircases, and balconies.
- Residential and commercial decks, stairs and balconies have railings to separate these structures from adjacent areas and prevent persons from falling off. The railings have top rails supported on upright posts that are attached to the decks and stairs. A number of laterally spaced upright members also typically extend between the top rails and the decks and/or stairs.
- Upright post attachment for railings has been accomplished by many means. To ensure a strong connection, a carpenter/builder will typically use ½″ diameter through bolts to attach 4×4 upright wood posts to the deck rim, and the posts then support a horizontal top rail. Sometimes the builder will notch the posts to custom fit to the decking, while others will not. Some will attach the posts to the inside edge of the deck, while others secure the posts to the outside edge of the deck. Also, some builders will use a top bolt anchor method, mounting a post on top of the deck and affixing the post via multiple bolts and/or screws into the structural members of the deck material, such as the rim beams and joists. When bolts or screws penetrate in this way, it becomes very easy (for example, due to over-tightening of the penetrating bolts) to crush the wood fibers of the structural members and diminish the strength of the connection. Over time, collection of water and erosion within the bolt holes can lead to premature structural failure, including splintering, mold growth and rotting.
- In addition to the use of through bolts, there are a number of patented devices which use a system of mounting brackets, plates, hollow tubes and/or mounting sleeves for securing posts to mounting surfaces. Such systems can have drawbacks, such as difficulty in installation of multiple bolts, plates and brackets. All of these systems puncture a deck's structural components in one fashion or another. Also, these bracket systems can become loose and unstable over time.
- Accordingly, there is a need for an upright rail post anchoring system and method for use on a diversity of mounting surfaces which can provide superior structural rigidity and strength and strong securing capacity without creating holes in the substance of the deck material or its supporting members, so that there is no rotting, splintering or other type of erosion over time, and which utilizes an uncomplicated design that is easy to manufacture and install in both new and retrofit applications.
- The present invention provides a rail post attachment system and method that eliminates the need for penetrating the structural members of the deck material. The system typically includes a securing member which fastens an upright post or railing member against a deck or floor rim beam. Specifically, the securing member can be a large, square clench bolt, a clench strap (either formed or welded), or clench brackets, as described herein. The inventive system and method can be used to install railings for decks, staircases and/or balconies, and can be used on structures made of wood, fiber, steel, concrete or other synthetic composite materials.
- A first aspect of the invention provides a system, in a railing for a deck, stairway or balcony, comprising: (a) an anchored horizontal rim beam; (b) a plurality of railing members; and (b) a plurality of securing members for fastening the plurality of railing members in an upright and perpendicular orientation against the horizontal rim beam, wherein each one of the securing members is fitted about the rim beam and fastened to one of the plurality of railing members, thereby securing the railing member against the rim beam. Typically each railing member is laterally spaced along the length of the rim beam a predetermined distance from the preceding railing member.
- A second aspect of the invention provides a railing for a deck, stairway or balcony, comprising: (a) a plurality of laterally spaced railing members; (b) an anchored horizontal rim beam; and (c) a plurality of securing members for attaching the plurality of railing members against the rim beam in general vertical alignment with the rim beam.
- A third aspect of the invention provides a method of constructing a railing system, comprising the steps of: (a) providing a plurality of securing members and a plurality of railing members for fastening to an anchored horizontal rim beam; (b) aligning a first railing member of the plurality of railing members in a vertical position with the horizontal rim beam; (c) fitting a first securing member about the rim beam; (d) connecting the first securing member against the first railing member; (e) securing the rim beam against the first railing member by tightening the connection between the first securing member and the first railing member; and (f) repeating steps (b) through (e) with subsequent securing members and railing members, each railing member being laterally spaced along the length of the rim beam a predetermined distance from the preceding railing member.
- These and further objects, features, advantages and characteristics of the system and method of the present invention will be more fully appreciated upon viewing the following drawings, detailed description of the preferred embodiments, and claims.
- The accompanying drawings illustrate embodiments of the invention and, together with a general description of the invention given above, and the detailed description given below, serve to explain the principles of the invention.

FIG. 5 is a perspective view as seen from the outside of a deck showing various embodiments of a securing member of the invention, including the formed clench strap, clench brackets, welded clench strap, and square clench bolt. - As defined herein, the term “railing member” is a vertically-oriented post, baluster, support, column, spindle, picket, rod, bar, pole, stake, shaft, pillar, beam or the like, which forms and supports a railing section of a deck, stairway, balcony, parapet or the like. In a preferred embodiment, the railing member is a supportive post for a top rail or railing cap of a railing section, and is typically located at the corners of a deck and at regular intervals in between. A railing member can be made of materials such as wood, stone, steel, concrete, iron, plaster, polyurethane, or other polymeric materials.
- The terms “rim beam,” “perimeter joist” or “rim joist” mean a horizontally-oriented beam, truss or joist which railing members can be secured to. The rim beam is typically anchored to the joist ends of a deck, stairway, or balcony. As a non-limiting example, the floor joists of a deck provide support for the flat decking boards (usually 16 inches on center), and the “rim beam,” “perimeter joist” or “rim joist” as defined herein can be attached to the ends of the floor joists, typically on the sides of the deck situated away from the house or fixed structure.
- The present invention is a railing system and method of constructing such, including a plurality of upright railing members or posts in combination with a plurality of securing members.
FIG. 1 illustrates a perspective view of the main elements of adeck 10 constructed using the system and method of the present invention, as viewed from inside the deck. The main decking, including theframing joists 12, thedeck flooring 14 and the rim beam 16 (also known as a rim joist or perimeter joist) are typically installed first (or have been previously installed, e.g. in retrofit applications), prior to the railing system installment. Eachrailing member 18 is vertically mounted against the structure of therim beam 16 by a plurality of securingmembers 20, which fasten together the plurality ofrailing members 18 in an upright and perpendicular orientation against thehorizontal rim beam 16. As illustrated, eachrailing member 18 is typically laterally spaced along the length of the rim beam 16 a predetermined distance from the preceding railing member. - In the embodiment shown in
FIG. 1 , therailing members 18 are steel angle posts, typically 2.5 inches×2.5 inches× 3/16 inches, with pre-drilled holes for fitting stainlesssteel wire rope 22 therethrough. Atop railing cap 24 is attached by a bolt or screw 25 onto the top portion of eachpost 18, with thewire rope 22 strewn horizontally through holes in thesteel angle posts 18 between thecap 24 and thedeck flooring 14. Thewires 22 are equally horizontally spaced to meet local codes (typically 10 rows), and therailing cap 24 is typically 2 inches×3 inches× 3/16 inch steel, bolted to eachsteel angle post 18. Therailing members 18 can vary in height, but should at least be tall enough to meet local codes, and are typically between 30 inches and 45 inches above the deck surface. Other building methods besides horizontally strewn wire rope can be used between the main vertical posts as well, in order to meet local building codes. These include any type of vertical railing member as defined herein, and can be made of materials such as wood, glass, Plexiglas, wire mesh, or other panel material. - In
FIG. 2 the securing member is asquare clench bolt 26, which is a cylindrical threaded fastener with square shoulders that is affixed about therim beam 16 and fastened to therailing member 18. Theclench bolt 26, like all of the securing members disclosed herein, thus fastens therailing member 18 against the outside vertical face of thehorizontal rim beam 16 without creating holes in the substance of the rim beam, deck material or its supporting members. As illustrated, thesquare clench bolt 26 includes two externally threadedlegs railing member 18, ashoulder portion 27 c between each of the legs for fitting about the inside vertical face of therim beam 16, and two internally threadednuts 28 a, 28 b, for screwing on to the threadedlegs shoulder portion 27 c of the clench bolt is placed about the inside vertical face of thehorizontal rim beam 16, thenuts 28 a, 28 b are screwed onto the legs. Tightening of thenuts 28 a, 28 b above and below (respectively) therim beam 16 causes therailing member 18 to be fastened against the outside vertical face of therim beam 16, with no penetration of any bolts or creation of holes in the substance of the rim beam. - The size and type of securing member chosen can depend on the size and dimensions of the
rim beam 16. The inside dimensions of aclench bolt 26, as shown inFIG. 2 , installed at the end of thedeck flooring 14, has a vertical height ‘H’ of between 5.0 inches and 14.0 inches betweenleg portions legs shoulder portion 27 c of thebolt 26 have a diameter between 0.5 inches and 1.0 inches. Thelegs nut 28 a, 28 b. Typically a perimeter joist orrim beam 16 around which thebolt 26 fits is between 0.5 inches and 8.0 inches wide/thick, more typically between 1.5 inches and 3.0 inches wide, and is typically made of wood or steel, but can also be any synthetic structural material on the market. - As a non-limiting example, the
shoulder portion 27 c of thesquare clench bolt 26 as shown inFIG. 2 has a height ‘H’ of 7.25 inches, thelegs clench bolt 26 is fitted around a (previously installed/anchored) 1.5inch rim beam 16, and thelegs wooden post 18. Fastening of theclench bolt 26 to thepost 18 after fitting the shoulders of thebolt 26 about therim beam 16 creates a sturdy and secure connection without creating any holes in or otherwise penetrating the rim beam itself. - In addition to the
square clench bolt 26 ofFIG. 2 ,FIG. 3 illustrates various other embodiments of a securing member, namely a formedclench strap 30, a pair ofclench brackets 32, or a weldedclench strap 34. The formedclench strap 30 is similar to thesquare clench bolt 26, but the shoulder and leg portions are typically flat instead of cylindrical, and the legs include foot portions with a hole therethrough for passing a bolt. The flat shoulder portion of theclench strap 30 can thus fit snugly with therim beam 16. Theclench brackets 32 are similar to theclench strap 30, but is a two-piece apparatus having two separated shoulder/leg portions that can be spaced apart to accommodate any size rim beam (i.e. a horizontal rim beam of any vertical height). - The welded
clench strap 34 ofFIG. 3 is typically used in conjunction with a steel angle post 18 (or other steel type post) as therailing member 18, and includes asingle leg 35 that is welded to thepost 18, while opposite the single leg 35 (at the lower end of the railing member 18) a threaded bolt and nut combination is included for passing through holes at the lower end of the shoulder portion and thepost 18, thereby securing/fastening/clenching thepost member 18 against therim beam 16. It can be appreciated that thesingle leg 35 of theclench strap 34, which is welded to thepost 18, must be substantially the same length as the thickness of therim beam 16 to ensure a snug fit. This is better visualized inFIG. 4C . Also, from viewingFIG. 3 (better shown inFIGS. 4A and 4B ) it can be appreciated that both the formedclench strap 30 and theclench brackets 32 include legs with foot portions having holes that receive bolts therethrough, and two nuts for screwing on to the bolts, thereby securing therailing member 18 against therim beam 16. - In practice, the
rim beam 16 is seated within the shoulder portion(s) prior to passing the bolts through the holes of the legs, which is then followed by passing the bolts through therailing member 18. Typically the railing member 18 (e.g. a steel type post) will have pre-manufactured holes that can line up with the hole(s) of the securing member. However, holes can also be drilled through the railing member, if not already present. The nuts 43 a, 43 b are then screwed on to theircorresponding bolts 42 a, 42 b and tightened, thereby securing therailing member 18 against therim beam 16. This is illustrated in better detail inFIGS. 4A-4C . -
FIGS. 4A-4C illustrate the formed clench strap, clench brackets, and welded clench strap embodiments of the securing member of the present invention. The formedclench strap 30 ofFIG. 4A includes twoleg portions foot portion holes bolts 42 a, 42 b through both thecorresponding foot portion railing member 18. Ashoulder portion 40 c is placed around therim beam 16. Thestrap 30 is placed around therim beam 16 so that the rim beam is seated within theshoulder portion 40 c and between theleg portions bolts 42 a, 42 b through theholes railing member 18. Two internally threaded nuts 43 a, 43 b are then screwed on to theircorresponding bolts 42 a, 42 b and tightened, fastening therailing member 18 against therim beam 16. Theshoulder portion 40 c of the formedclench strap 30 can have a height of between 5.0 inches and 14.0 inches betweenleg portions Bolts 42 a, 42 b are typically between 2 inches and 8 inches long, in order to pass through therailing member 18. - The
clench brackets 32 ofFIG. 4B are a two-piece apparatus having two separate shoulder/leg portions 50 a, 50 b, each of which include afoot portion 54 a, 54 b having a hole, 51 a and 51 b respectively, for passing threadedbolts 52 a, 52 b through the corresponding foot portion andrailing member 18. Two internally threaded nuts 53 a, 53 b screw on to the externally threadedbolts 52 a, 52 b and tighten each of the shoulder/leg portions 50 a, 50 b to therailing member 18. Thebrackets 32 are placed about therim beam 16 so that the rim beam is seated between the shoulder/leg portions 50 a, 50 b, with the shoulders of each shoulder/leg portion fitting around the edge of therim beam 16, prior to passing the bolts through the holes 51 a, 51 b andrailing member 18 and tightening the nuts 53 a, 53 b. As noted above, the separate shoulder/leg portions 50 a, 50 b can be spaced apart to accommodate the vertical height of any size rim beam. Leg lengths and bolt sizes can be the same as disclosed above for the formedclench strap 30. - The welded
clench strap 34 ofFIG. 4C includes asingle leg 35 that is welded to asteel railing member 18, and ahole 61 through the lower end of theshoulder portion 60 opposite thesingle leg 35. A threadedbolt 62 andnut 63 combination is used for tightening theshoulder portion 60 to therailing member 18 after being fitted about therim beam 16. This nut and bolt combination (with complimentary female and male threads) fastens thepost 18 against therim beam 16. As noted above, it can be appreciated that thesingle leg 35 of theclench strap 34, which is welded to thepost 18, must be substantially the same length as the width/thickness of therim beam 16, which as noted above is typically between 0.5 inches and 8 inches thick, and more typically 1.5 inches and 3.0 inches thick. Also, the weldedclench strap 34 is typically used in conjunction with a steel type post as therailing member 18, as it can be easily welded thereto prior to use. -
FIG. 5 illustrates a perspective view of adeck 10 constructed using the system and method of the present invention, as viewed from outside the deck. This view shows how the connections created by the various embodiments of the securing member of the present invention will look from outside the deck. It can be appreciate that thesquare clench bolt 26, the formedclench strap 30, theclench brackets 32, and the weldedclench strap 34 are all through-bolted (via a threaded bolt and nut combination) just above and below the structuralrim beam member 16, without any penetration of therim beam 16. Also, the weldedclench strap 34 is through-bolted just below therim beam 16, with the top portion being welded on the opposite side to a steel type post 18 (see alsoFIGS. 3 and 4C ). Thus, while the clench means of the present invention are primarily functional, for securing railing members against the rim beam of a deck without penetrating the structural members of the deck with bolts or nails, they also make the structure aesthetically pleasing to the viewer. - While the present invention has been illustrated by the description of embodiments and examples thereof, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will be readily apparent to those skilled in the art. Accordingly, departures may be made from such details without departing from the scope of the invention.
