Definitions
- This invention relates to the construction of buildings and specifically to those that utilize pre-manufactured components applied to a modified post-frame type skeleton resulting in an improved building.
- poles as columns or posts in post and frame construction was supplanted by the use of standard dimensional lumber, i.e., 2 ⁇ 4, 2 ⁇ 6 and 2 ⁇ 8 lumber.
- standard dimensional lumber i.e., 2 ⁇ 4, 2 ⁇ 6 and 2 ⁇ 8 lumber.
- the regular dimensions allowed construction of truer angles.
- the advent of treated rot resistant lumber allowed the dimensional lumber to be inserted into foundation holes in place of poles.
- the present system allows the columns to be squared using the girt panels.
- the Eberle building method also discloses individual purlins which are either laid down on top of the upper truss chord or there between.
- the use of the individual purlins as opposed again, to a prefabricated true and plumed purlin panels does not allow the roof trusses to conform to the square and true purlin panel.
- Failure to use a centering column requires the user of the Eberle construction method to undertake a series of complex measurements and the use of shims in order to insure the upper ends of the upper column sections are all level.
- Purlin panels also help to ensure that the trusses are installed straight, plum and at the correct spacing.
- Purlin panels provide a more effective type of bracing for the top chord (compression chord) compared to roof purlins that are set on top of the truss. This is because the drop-in panels brace more than just the top edge of the truss top chord; they brace the depth of the chords by butting into them from both sides. This not only prevents the chords from buckling laterally (out of the plane of the truss), it also resists the torsional (twisting) mode of buckling.
- Deep heel trusses provides for added stability to the structure during construction. Since connection of the post to the heel is more rigid than a normal heel because the bolts or nails can be spread apart and provide a moment connection between the post and truss. In this way, this connection works like a knee brace between the post and truss.
- the preferred embodiment of this method of construction will result in a post-frame building that will have side walls, end walls and a gabled roof formed from pre-manufactured trusses.
- the mechanism of support for the side walls, end walls and roof trusses will be a plurality of vertical columns 1 , (FIG. 1 ) each set into a hole in the earth 2 . Holes 2 are dug or bored into the ground forming the perimeter of the structure.
- the columns 1 are comprised of an upper column section 3 (FIG. 1A) and a lower column section 4 (FIG 1 B).
- the lower column section 4 is composed of three pieces of dimensional treated lumber and is approximately 8 feet in length.
- the dimensional lumber could consist of 2 ⁇ 4, 2 ⁇ 6, 2 ⁇ 8, 2 ⁇ 10, or 2 ⁇ 12 or various combinations thereof.
- the three pieces of dimensional lumber (FIG. 2) are a center piece 5 , a first outer piece 6 and a second outer piece 7 .
- the center piece 5 usually a 2 ⁇ 8 and the first outer piece 6 and the second outer piece 7 , usually 2 ⁇ 6's, are joined together in a laminated configuration using nails in such a manner that the lower end 8 and the upper end 9 as well as the rear face 10 of the lower column section 4 are flush.
- a transit is then used to determine a uniform level for the upper end of the column pieces for all lower column sections 4 on the building's perimeter. After cutting according to the transit, the top ends of the center column pieces are now level. Then approximately 2 feet of the upper end of first outer piece 6 is cut away from the column. Similarly, approximately 1 foot of the second outer piece 7 , is cut away. This results in the center piece 5 being the longest of the three components of the lower column section 4 , and results in the first outer piece 6 being the shortest component and finally second outer piece 7 having an intermediate length. The center column piece extends above the outer column pieces thereby forming a tongue 14 .
- center piece tongues 14 are all a uniform length in relation to the cut upper ends of first outer piece 6 and the second outer piece 7 . Lumber may be saved by using shorter pieces of dimensional lumber for the first outer piece 6 and the second outer piece 7 during the initial lamination.
- the upper column section 3 (FIG. 1A) is also composed of three pieces of dimensional lumber that, dependent upon the application, can be lumber of the same or different dimension as the lower column section 4 .
- the central column member 15 of the upper column section 3 is measured and cut to length such that if the length of the central column member 15 of the upper column section 3 is added to the above ground height of the center column piece 5 of the lower column section 4 , the truss to ground height is achieved.
- a first side member 16 and a second side member 17 are cut.
- the length of the first side member 16 is calculated by adding the following three distances; the distance a (FIG.

- the length of the second column member 17 (FIG. 1B) is determined by adding the distance d (FIG. 1B) from the upper end of the second side piece 7 of the lower column section 4 to the upper end of the central column piece 5 ; the distance b (FIG. 1) represented by the length of the center column member 15 of the upper column section 3 ; and the length c (FIGS. 1 and 5) of the truss heel 18 .
- the center column member 15 , (FIG. 1A) the first side member 16 and the second side member 17 are then nailed together in a laminated configuration.

- Laminating the 2 ⁇ 8 center column member 15 and the 2 ⁇ 6 first outer member 16 and the second outer member 17 results in a lip protruding approximately 1 and 1 ⁇ 2 inches from the front face of the upper column section 3 , just as was accomplished with the lower column section 4 (FIG. 2).
- first column member 16 extends below the central column member 15 a distance a′ (FIG. 1A) equal to the distance a (FIG. 1B) from the upper end of first column piece 6 to the top of the center column piece 5 .

- Girt panels for the end walls (FIG. 6) are manufactured to the length similar to that of the side wall girt panels less the distance represented by the depth of the heel 18 of the deep heel truss 23 .

Description
- This is a continuation of the parent application Ser. No. 09/305,175 which was accorded a filing date of May 4, 1999.
- This invention references, includes the subject matter and claims the benefit of previously filed provisional applications, No. 60/084,088, filed May 4, 1998; No. 60/100,910 filed Sep. 17, 1998 and No. 60/101,165 filed Sep. 21, 1998.
- 1. Field of Invention
- This invention relates to the construction of buildings and specifically to those that utilize pre-manufactured components applied to a modified post-frame type skeleton resulting in an improved building.
- 2. Developments in the Field
- The demand for strong yet economical buildings for commercial, industrial and agricultural applications has grown over the decades. In the agricultural context, barns were usually constructed of self-supporting heavy timber frames. One alternative to this construction method was the pole barn. This type of building was constructed by digging a series of holes around a perimeter of the to-be-constructed building. Long poles, such as wooden telephone or power poles, were set into the holes. Then numerous horizontal members called “girts” were then nailed to the poles increasing stability and providing a mechanism for attachment of exterior sheathing. The poles used in this method of construction were merely whole harvested timber with branches and bark removed. Consequently, the pole varied in diameter being generally wider and the base and narrower at the top. The poles, being a natural product were not uniform nor necessarily straight. This created significant problems in constructing a “square” buildings with true angles. This had further ramifications making the creation of properly functioning doorways and windows difficult. Since the poles narrowed and became less straight at the top, attachment of the roof rafters or trusses was difficult and sometimes irregular.
- The use of poles as columns or posts in post and frame construction was supplanted by the use of standard dimensional lumber, i.e., 2×4, 2×6 and 2×8 lumber. The regular dimensions allowed construction of truer angles. The advent of treated rot resistant lumber allowed the dimensional lumber to be inserted into foundation holes in place of poles.
- 3. Prior Art
- Of all prior art references, the one that comes the closest to the to the characteristics of this invention is the building system disclosed in U.S. Pat. No. 4,479,342 to Eberle. The Eberle building system utilizes a columnar structure wherein the lower column section sits on a pre-cast or poured concrete footing and is held in place by tamped earth. This could potentially allow wind sheer forces to lift the column from the hole thereby destroying or distorting the structure. Further, the lower section of the Eberle patent discloses a symmetrical slip joint which is inherently weaker than the staggered slip joints disclosed in this invention. The upper section of the Eberle column does not contain a center member. This requires the unnecessary step of inserting a leveling block between the upper column members to allow the insertion of a shallow heel truss. The use of a narrow-heeled truss in the Eberle patent requires the further utilization of the application of a knee brace. Utilization of deep heel trusses in this invention eliminates this particular disadvantage by providing significant stability and wind sheer resistance. Further, the Eberle building method utilizes either long girts nailed to the exterior of the sidewall columns, or girts nailed between and flush with the sidewall column lips. Utilization of individual girts instead of square and true girt panels, does not allow the columns to be plumed and leveled when the individual girts are applied. The present system allows the columns to be squared using the girt panels. The Eberle building method also discloses individual purlins which are either laid down on top of the upper truss chord or there between. The use of the individual purlins as opposed again, to a prefabricated true and plumed purlin panels does not allow the roof trusses to conform to the square and true purlin panel. Failure to use a centering column requires the user of the Eberle construction method to undertake a series of complex measurements and the use of shims in order to insure the upper ends of the upper column sections are all level.
- In addition to the objects and advantages of the Post-Frame Building heretofore described, additional objects and advantages of the present invention are as follows:
- (a) to reduce on site labor costs by utilizing pre-manufactured purlin and girt panel components. Through the use of jigs and machinery, the pre-manufactured girt and purlin panels are subject to higher quality control, can be manufactured to varying an exacting specifications and are manufactured with square and true angles.
- (b) to increase safety by reducing the number of components needing to be assembled thereby reducing the need for workers to work atop trusses and other elevated building components.
- (c) Drop in roof purlin panels provide added stability the structure during truss installation meaning more safety for the workers and less chance of damage to the structure before it is finished from severe weather (usually in the form of wind loads associated with thunder storms).
- (d) Purlin panels also help to ensure that the trusses are installed straight, plum and at the correct spacing.
- (e) Purlin panels provide a more effective type of bracing for the top chord (compression chord) compared to roof purlins that are set on top of the truss. This is because the drop-in panels brace more than just the top edge of the truss top chord; they brace the depth of the chords by butting into them from both sides. This not only prevents the chords from buckling laterally (out of the plane of the truss), it also resists the torsional (twisting) mode of buckling.
- (f) Deep heel trusses provides for added stability to the structure during construction. Since connection of the post to the heel is more rigid than a normal heel because the bolts or nails can be spread apart and provide a moment connection between the post and truss. In this way, this connection works like a knee brace between the post and truss.
- (g) The moment connection between the post and deep heel trusses stiffens the post-truss frame and reduces lateral building deflection under wind loads.
- (h) The moment connection between the post and deep heel trusses changes the moment distribution in the post and better utilizes the strength of the post.
- (i) The joining of columns by the use of staggered slip joints greatly increases the column's resistance to wind sheer.
- (j) The use of a center column in the upper column section greatly reduces time needed to measure and shim, a disadvantage of the prior art.
- (k) The use of purlin hangers allows the purlin panels to self position themselves and allows faster and more accurate attachment to roof trusses.
- The preferred embodiment of this method of construction will result in a post-frame building that will have side walls, end walls and a gabled roof formed from pre-manufactured trusses. The mechanism of support for the side walls, end walls and roof trusses will be a plurality of
vertical columns 1, (FIG. 1 ) each set into a hole in theearth 2.Holes 2 are dug or bored into the ground forming the perimeter of the structure. Thecolumns 1 are comprised of an upper column section 3 (FIG. 1A) and a lower column section 4 (FIG 1B). Thelower column section 4 is composed of three pieces of dimensional treated lumber and is approximately 8 feet in length. Depending on the size of the building and on the application, the dimensional lumber could consist of 2×4, 2×6, 2×8, 2×10, or 2×12 or various combinations thereof. The three pieces of dimensional lumber (FIG. 2) are acenter piece 5, a firstouter piece 6 and a secondouter piece 7. Thecenter piece 5, usually a 2×8 and the firstouter piece 6 and the secondouter piece 7, usually 2×6's, are joined together in a laminated configuration using nails in such a manner that thelower end 8 and theupper end 9 as well as therear face 10 of thelower column section 4 are flush. In this fashion, laminating the 2×8center piece 5 and the 2×6 firstouter piece 6 and the secondouter piece 7, results in alip 11 protruding approximately 1 and ½ inches from the front face of thelower column section 4. The lip can vary in protuberance depending on the dimensional lumber used and the application. Nailing of thelower column section 4, proceeds from thelower end 8 toward theupper end 9 stopping approximately 2 ½ feet from theupper end 9. The lower end 8 (FIG. 3) of thelower column section 4 is then drilled through to accept a length ofmetal rod 12. Depending upon the application, thelower column section 4 may be drilled to accept one or more metal rods. Thelower end 8 is set into thehole 2 and concrete 13 is inserted into the bottom of thehole 2. Thelower column section 4 is fixed in a plumbed and leveled position allowing the concrete 13 to set. - After the concrete13 (FIG. 4) is set, a transit is then used to determine a uniform level for the upper end of the column pieces for all
lower column sections 4 on the building's perimeter. After cutting according to the transit, the top ends of the center column pieces are now level. Then approximately 2 feet of the upper end of firstouter piece 6 is cut away from the column. Similarly, approximately 1 foot of the secondouter piece 7, is cut away. This results in thecenter piece 5 being the longest of the three components of thelower column section 4, and results in the firstouter piece 6 being the shortest component and finally secondouter piece 7 having an intermediate length. The center column piece extends above the outer column pieces thereby forming atongue 14. An added result is that thecenter piece tongues 14 are all a uniform length in relation to the cut upper ends of firstouter piece 6 and the secondouter piece 7. Lumber may be saved by using shorter pieces of dimensional lumber for the firstouter piece 6 and the secondouter piece 7 during the initial lamination. - The upper column section3 (FIG. 1A) is also composed of three pieces of dimensional lumber that, dependent upon the application, can be lumber of the same or different dimension as the
lower column section 4. Thecentral column member 15 of theupper column section 3 is measured and cut to length such that if the length of thecentral column member 15 of theupper column section 3 is added to the above ground height of thecenter column piece 5 of thelower column section 4, the truss to ground height is achieved. After thecentral column member 15 has been cut to length, afirst side member 16 and asecond side member 17 are cut. The length of thefirst side member 16 is calculated by adding the following three distances; the distance a (FIG. 1B) from the upper end of thefirst side piece 6 of thelower column section 4 to the upper end of thecentral column piece 5; the distance b (FIG. 1) represented by the length of thecenter column member 15 of theupper column section 3; and the length c (FIGS. 1 and 5) of thetruss heel 18. The length of the truss heel (FIG. 5) is determined by the size and length of the dimensional lumber used forupper truss member 19, thelower truss member 20, and the verticalheel support member 21. - The length of the second column member17 (FIG. 1B) is determined by adding the distance d (FIG. 1B) from the upper end of the
second side piece 7 of thelower column section 4 to the upper end of thecentral column piece 5; the distance b (FIG. 1) represented by the length of thecenter column member 15 of theupper column section 3; and the length c (FIGS. 1 and 5) of thetruss heel 18. Thecenter column member 15, (FIG. 1A) thefirst side member 16 and thesecond side member 17 are then nailed together in a laminated configuration. - Similar to the configuration of the
lower column section 4, thecenter column member 15, of theupper column section 3, usually a 2×8 and the firstouter member 16 and the secondouter member 17, usually 2×6's, are joined together in a laminated configuration using nails, in such a manner that the rear face of theupper column section 3 is flush. Laminating the 2×8center column member 15 and the 2×6 firstouter member 16 and the secondouter member 17, results in a lip protruding approximately 1 and ½ inches from the front face of theupper column section 3, just as was accomplished with the lower column section 4 (FIG. 2). - The lower end of first column member16 (FIG. 1A) extends below the central column member 15 a distance a′ (FIG. 1A) equal to the distance a (FIG. 1B) from the upper end of
first column piece 6 to the top of thecenter column piece 5. The lower end of thesecond column member 17, extends below the central column member 15 a distance d′ (FIG. 1A) equal to the distance d (FIG. 1B) from the upper end offirst column piece 7 to the top of thecenter column piece 5. This configuration results in the lower end of theupper column section 3 forming a staggered slip joint (FIG. 1A) capable of accepting the tongue 14 (FIG. 1B) of thelower column section 4 such that the lower ends of thecentral column member 15, (FIG. 1)first column member 16 andsecond column member 17 meet the upper ends of thecenter column piece 5, thefirst column piece 6 and thesecond column piece 7, respectively. Thetongue 14 of thelower column section 4 is inserted into the slip joint formed by the staggered lamination of the members of the upper column section and nailed to join theupper columns section 3 andlower column section 4 into a single unit. - Lamination of the upper column members in this fashion also produces a sleeve (FIG. 1A) on the upper end of the upper column section formed by the equidistant extension of the upper ends of
first column member 16 andsecond column member 17 beyond the upper end of thecentral column member 15. The upper ends of first column member 16 (FIG. 5) andsecond column member 17 are then cut at an angle matching the angle of theupper truss chord 22 and to a length such that the upper ends offirst column member 16 andsecond column member 17 are flush with theupper truss chord 22. The construction ofcolumns 1 is repeated around the perimeter of the building approximately 4 to 10 feet apart, until the required plurality is achieved. - Column construction for columns on the end walls of the post frame building are identical to those for the side walls except the
column 1′ (FIG. 6) is oriented within the structure facing outward to accept anend gable truss 24. The bottom chord ofend gable truss 25 rests onlip 11. Columns set in this configuration are repeated on the end walls at four to ten feet intervals, until the required plurality is achieved. Further, lumber may saved and girt panel application may be enhanced by using corner columns, both upper and lower sections, constructed of only a center member and a single offset outer member. - An added structural component for the end wall column is
gable column extension 26. Thegable column extension 26 is dimensional lumber cut to varying lengths for each end column in order to make contact with theupper truss member 19. Thegable column extension 26 is then set into the sleeve formed by the firstouter column members 16 and the secondouter column member 17 that normally accepts thetruss heel 18 under the side wall column configuration. The longestgable column extension 26 will correspond to the peak of the end gable truss and the shortest will correspond to the end wall column set closest to the side walls. - The primary component of the side and end walls is a prefabricated girt panel24 (FIG. 7) which spans the distance between columns (FIG. 8). The prefabricated girt panel 24 (FIG. 7) is formed from dimensional lumber when two parallel
vertical members 25 are joined with an array ofhorizontal members 26 being configured at right angle to the vertical members. The ends of thehorizontal members 26 are abutted to the parallelvertical members 25 and are joined to one another by any standard means, with atruss plate 27 being the preferred method of attachment. Dimensional lumber of any size may be used to construct thegirt panel 24, however, 2×4 lumber is standard. Thegirt panels 24, are configured with the longer dimension of the lumber i.e., the 3 and ½ inch width forming theface 28 of the vertical 25 andhorizontal members 26. This results in the depth of thegirt panel 24 being approximately 1 and ½ inches. The girt panel may be fabricated to any width necessary to span the distance between the columns and may be manufactured to any height necessary to accommodate the appropriate truss to ground distance. - The girt panel24 (FIG. 8) is then raised and placed in between the
columns 1. Thevertical members 25 ofgirt panel 24 are mounted against, between and flush with thecontinuous lip 11 formed from the of the conjoined lips of thelower column section 4,upper column section 3 and protrudingheel 18 of thedeep heel truss 23. The verticalgirt panel members 25 are then nailed into the column. This is repeated betweencolumns 1 until each and everycolumn 1 forming the perimeter of the building is similarly joined. Girt panels for the end walls (FIG. 6) are manufactured to the length similar to that of the side wall girt panels less the distance represented by the depth of theheel 18 of thedeep heel truss 23. In this way, the end wall girt panels can be mounted under and flush with the bottom member of thegable end truss 20 and between and flush with the endwall columns lips 11. - After girt panel application a deep heel truss23 (FIG. 5) is then inserted into the sleeve formed from first
outer column member 16 and secondouter column member 17. Thedeep heel truss 23 is constructed to length such that it extends approximately 1 and ½ inches beyond the sleeve formed by firstouter member 16 and firstouter member 17. This extension is designed to rest on and be a continuation of thelip 11. Thedeep heel truss 23 is secured within the sleeve by nails being driven through the firstouter member 16 and secondouter member 17 into theheel 18 of the deep heldtruss 23. This process is continued with opposing side wall trusses accepting opposing ends of the same truss, until all side wall columns and around the perimeter have accepted trusses. - A primary component of the roof is a prefabricated purlin panel29 (FIG. 9). The
prefabricated purlin panel 29 is formed when two parallelvertical members 30 are joined with an array ofhorizontal members 31 being configured at right angle to the vertical members. The ends of thehorizontal members 31 are abutted to the parallelvertical members 30 and are joined to one another by any standard means with atruss plate 32 being the preferred method of attachment. Dimensional lumber of any size may be used to construct thepurlin panel 29, however, 2×4 lumber is standard. Thepurlin panels 29, are configured with the shorter dimension of the lumber i.e., the 1 and ½ inch width forming theface 33 of the vertical 30 andhorizontal members 31. This results in the depth of thepurlin panel 29 being approximately 3 and ½ inches. The purlin panel 29 (FIG. 10) is then lifted above the trusses and lowered into position between the deep heel trusses 23 and flush with the top chord of thetruss 22 and then nails are driven through thevertical members 30 into theupper truss member 19 of thedeep heel truss 23. - The
purlin panel 29 may either be suspended and manually held in place while being nailed to theupper truss member 19 or it may be suspended by means of a purlin hanger 34 (FIG. 11). Thepurlin hanger 34 is of metal or other suitable material and is placed on the upper member of atruss 19 and in a corresponding position on an adjacent truss the purlin panel is being lowered between. Thepurlin hanger 34 and is composed of avertical segment 35 for attachment to theupper truss member 19, ahorizontal segment 36 upon which thenarrow face 33 of thevertical purlin member 30 rests. The final segment of thepurlin hanger 34 is the purlin panel receptacle face 37 (FIGS. 11 and 11B). When apurlin panel 29 is lifted above the truss line and lowered in place between theupper truss members 19 the vertical purlin member 30 (FIG. 12) makes contact with the purlinpanel receptacle face 37. As thevertical purlin member 30 along with theentire purlin panel 29 continues to be lowered the angular nature of the purlin panel receptacle face 37 forces theupper truss member 19 into alignment with the verticalpurlin panel member 30 which as it slides down the purlin panel receptacle face 37 finally resting on thehorizontal segment 36 of thepurling hanger 34. At this point, the upper face 41 (FIG. 11B) of thevertical purlin member 30 will be flush with theupper chord 22 of theupper truss member 19. A similar mechanism simultaneously positions the opposing vertical purlin member against the adjacent truss the purlin panel is being placed between. Purlin hangers may be used in the necessary plurality on adjacent trusses to properly support and position a purlin panel. Alternative embodiments (FIGS. 13 and 13A) wherein the purlin hanger is suspended form the top chord of theupper truss member 19 are illustrated. Here thevertical purlin segment 40 now appears above the horizontal purlin segment and is wrapped up and over the upper chord of theupper truss member 19. Thevertical purlin segment 40 may either be secured or hang from the upper truss member. - Ceiling panels also containing vertical and horizontal members are constructed. The panels are then placed between the trusses and flush with the top chord of the truss. Columns as well as girt, purlin, ceiling panels can also be constructed of dimensional steel components with standard metal joinery and would be an appropriate choice depending on the application.
- After the columns are set and constructed, the girt panels are attached thereto. The deep heel trusses are mounted onto the columns and the purlin panels are then applied to and the upper truss members. A suitable sheathing, such as metal, for the side an end walls in then applied as well as a suitable roofing material. Modifications in the girt panels such as the addition of headers and lintels will allow doors and windows essentially completing the structure.
