A wooden profiled lumber is disclosed. The profiled lumber comprises two flange portions interconnected by an integral web portion of generally smaller thickness than the flange portions and formed by removing between 15 and 50% of the material of the central portion of the opposite walls of a rectangular lumber.
Description
This invention relates to wooden profiled lumber for use in the construction and related industries~
Wood lumber commonly used by the building industry i5 of rectangular shaped cross-section. However, for a large number of applications, the actual strength properties of lumber, as a building material, are far greater than structurally requirPd. It would, therefore, be advantageous to design and engineer lumber material to the dimensions re~uired to satisfy the minimum strength requirement. This would not only reduce the cost of material, but also reduce the weight o the lumber thereby lowering the transportation cost. However, the size of the lumber material cannot be reduced below a minimum needed for providing a min;mllm surface area for nailing or otherwise joining together the various construction elements, or or satisfying other construction needs. For example, the thickness of lumber must be such as to allow adequate surface area or nailing the edges of two adjacent panels onto the edge of the lumber, or its width sufficient to provide adequate air or insulation in the spacing between two opposite wallsO
The invention comprises a wooden construction element having a predetermined length and having a cross-sectional shape comprising a first flange portion and a second flange portion, said first and second flanye portions being of essentially identical predetermined thickness and essentially iden~ical predetermined width, said first and second 1ange portions being parallel to one another relative to their thickness dimension and int~rconn~cted by a central integral web portion comprising a uniform thickness section having a predetermined width and a ~;
O C ~ O O
thickness about one third of that of said flange portions, a first transition section having a width about equal to that of said first flange port.ion and connecting said first flange portion and said uniform thickness section and having a thickness tapering from that of said first flange portion to that of said uniform thickness section, and a second transition section having a width about equal to that of said second flange portion and connecting said second fange portion and said uniform thickness section and having a thickness tapering from that of said second flange portion to that of said uniform thickness section, said predetrmined width of said uniform thickness section being about equal to three times the width oE
one of said flange portions.
The profiled lumber, in accordance with the present invention, may comprise two flange portions interconnected by an integral web portion of generally smaller thickness than the flange portions and formed by removing between 15 and 50~ of the material of the central portion of the opposite walls of a rectangular lumber.
The shaping of the lumber is preferably performed by forming a groove in each wall of the rectangular lumber. The ae~tual width of the groove is preferably such that the material removed is about equal to the sum of that width of the material left in the two flanges. The actual thickness of the web portion of the profiled lumber would depend on the end use of the product, but is preferably not less than one thi.rd of the flange thickness.
The web material can be removed by routing or with 7~
conventional chip and saw type machinery. T~le excess material may advantageously be used to make chips for the pulping industry, for making moulding material, or used as an energy source.
As a second feature of the present invention, the above disclosed profiled lumber can form part of a building sys~em wherein cut to measure transverse lumber elements J having their end shaped to fit into the grooves of two profiled lumbers, are used to fix the distance between the profiled lumbers. Such a system would permit unskilled workers to assemble the structural framework of the building strongly and accurately without having to cut or measure material. They will also hold lumber ~ ~r~7~
accurately in place to enable unskilled workers to frame buildings squarely and accurately to the correct dimensions for standard material and fittings that are later added.
The invention will now be disclosed, by way of example, with reference to the accompanying drawings in which:
Fiyure 1 illustrates the cross-sectional shape of a conventional lumber;
Figures 2-5 illustrate some possible cross-sectional shapes of profiled lumbers in accordance with the invention;
Figure 6 shows interlocking of the profiled lumbers for shipping; and Figure 7 illustrates a simplified use of the profiled lumbers in accordance with the invention in a novel building concept based on the utilization of pre-cut transverse members having end portions which are affixed in the grooves of the profiled lumbers between adjacent lumbers.
Referring to Figures 1-4, there is shown in the extreme left view (Figure 1) a cross-section of a conventional 2" x 4"
lumber or stud 10 as commonly used in the building industry, particularly for constructing residential dwellings. The three right hand views (Figures 2-4) show differing cross-sectional views of profiled studs which may be manufactured by making rectangular or trapezoidal grooves in the walls of the conventional stud of Figure 1 using a chipping machine having suitably shaped chipper heads. The ~;m~sions given in Figure 1 are the approximate dimensions of a conventional

The invention comprises a wooden construction element having a predetermined length and having a cross-sectional shape comprising a first flange portion and a second flange portion, said first and second flanye portions being of essentially identical predetermined thickness and essentially iden~ical predetermined width, said first and second 1ange portions being parallel to one another relative to their thickness dimension and int~rconn~cted by a central integral web portion comprising a uniform thickness section having a predetermined width and a ~;

thickness about one third of that of said flange portions, a first transition section having a width about equal to that of said first flange port.ion and connecting said first flange portion and said uniform thickness section and having a thickness tapering from that of said first flange portion to that of said uniform thickness section, and a second transition section having a width about equal to that of said second flange portion and connecting said second fange portion and said uniform thickness section and having a thickness tapering from that of said second flange portion to that of said uniform thickness section, said predetrmined width of said uniform thickness section being about equal to three times the width oE
one of said flange portions.
The profiled lumber, in accordance with the present invention, may comprise two flange portions interconnected by an integral web portion of generally smaller thickness than the flange portions and formed by removing between 15 and 50~ of the material of the central portion of the opposite walls of a rectangular lumber.
The shaping of the lumber is preferably performed by forming a groove in each wall of the rectangular lumber. The ae~tual width of the groove is preferably such that the material removed is about equal to the sum of that width of the material left in the two flanges. The actual thickness of the web portion of the profiled lumber would depend on the end use of the product, but is preferably not less than one thi.rd of the flange thickness.
The web material can be removed by routing or with 7~
conventional chip and saw type machinery. T~le excess material may advantageously be used to make chips for the pulping industry, for making moulding material, or used as an energy source.
As a second feature of the present invention, the above disclosed profiled lumber can form part of a building sys~em wherein cut to measure transverse lumber elements J having their end shaped to fit into the grooves of two profiled lumbers, are used to fix the distance between the profiled lumbers. Such a system would permit unskilled workers to assemble the structural framework of the building strongly and accurately without having to cut or measure material. They will also hold lumber ~ ~r~7~
accurately in place to enable unskilled workers to frame buildings squarely and accurately to the correct dimensions for standard material and fittings that are later added.
The invention will now be disclosed, by way of example, with reference to the accompanying drawings in which:
Fiyure 1 illustrates the cross-sectional shape of a conventional lumber;
Figures 2-5 illustrate some possible cross-sectional shapes of profiled lumbers in accordance with the invention;
Figure 6 shows interlocking of the profiled lumbers for shipping; and Figure 7 illustrates a simplified use of the profiled lumbers in accordance with the invention in a novel building concept based on the utilization of pre-cut transverse members having end portions which are affixed in the grooves of the profiled lumbers between adjacent lumbers.
Referring to Figures 1-4, there is shown in the extreme left view (Figure 1) a cross-section of a conventional 2" x 4"
lumber or stud 10 as commonly used in the building industry, particularly for constructing residential dwellings. The three right hand views (Figures 2-4) show differing cross-sectional views of profiled studs which may be manufactured by making rectangular or trapezoidal grooves in the walls of the conventional stud of Figure 1 using a chipping machine having suitably shaped chipper heads. The ~;m~sions given in Figure 1 are the approximate dimensions of a conventional
2" x 4" lumber and the dimensions given in Figures 2-4 are the approximate dimensions of the grooves made in the 6 ~ ~
walls of the conventional lumber. The profiled lumber so produced comprises two parallel flanges 12 joined by an integral web portion 14. In Figure 2, the wood material removed by making a rectangular groove in the wall of a con-ventional lumber is about 20% of the original lumber material,thus reducing the weight thereof by 20%-30% depending on ~he density of the wood species used, and, consequently~ the transportation cost by an equal amount. In Figure 3, the wood material removed by making a deeper groove in the wall of a con~entional lumber, is about equal to 40% of the orig-inal lumber material, thus reducing the weight thereof by 40%-45%. Figure 4 shows a dog-bone shaped cross-section pro-duced by making a trapezoidal groove in the wall portion of a conventional lumber. This provides about the same amount of wood reduction as in Figure 3, but reduces the possibility of splitting the edges of the profiled lumber when nailing panels to the edges of the lumber. Figure 5 shows the pre-ferred shape and dimensions to provide the best compromise between strength and weight.
The width of the groove in the web portion of the pro-filed lumbers of Figures 2-5 is preferably about equal to the width of the material left in the two flanges. This leaves sufficIent material for adequate nailing or otherwise s-ecuring panels or other structural elements to the edges of ~he lumbers. This particular shape is also designed to allow interlocking of the profiled lumbers for shipping in such a way that they fit together like a jigsaw to optimize volume savings, as shown in Figure 6. This shape also 7~
avolds the use of "sticking" when shipping the lumber.
The ac~ual thickness of the web portian of the profiled lumber depends on the strength properties required for the end use of the product. For a large number of applica~ions, such thickness would be ahout a third of the overall thickness of the original lumber, such as shown in Figure 3, 4 and 5 of the drawi~gs.
It has been found that the above shaping of regular lumbers into profiled lumbers reduces the lumber strength properties but, as mentioned previously, the strength properties of lumber are far greater than structurally required in many applications, and the cross-sectional area of the lumber can be easily reduced by a substantial amount for these applications. The excess wood material ]5 removed would provide additional usable material from a given volume of wood. The material can advantageously be used to make chips for the pulping industry, moulding materials or used for energy cons~ption.
There is a shortage in North America far wood chips suitable for use in pulp and paper mills. Thus, the end use of profiled lumber may yield a considerable volume of pulp wood chips without a commensurate xeduction in the quantity of lumber available for use in the building construction industry.
Other advantages of the profiled lumber in accordance with the invention are:
a) the shape of the profiled lumber reduces the stress points in the lumber when drying so reducing the splitting and checking that takes place during the dxying process;
b) the grooves in the web portion of the profiled lumber permit improved flow of air in the kilns resulting in more rapid and efficient drying of wood;
c) the groove in the web portion of the profiled lumber also provides extra surface areas to simplify and i~prove the holding power of the fasteners used.
Although the invention has been disclosed with reference to the preferred embodiments shown in Figures 2-5, it is ~o be understood that the shape of the groo~es formed in the web portlon of the profiled lumbers may be varied according to the end use of the lumbers and that the invention is not limited to the shapes disclosed above.
A second basic concept which is derived from the use of profiled lumbers such as disclosed is shown in simplified form in Figure 7 of the drawings. There is shown a building section constructed using cut to length profiled lumbers of uniform cross-sectional shape, which shape is selected so that individual component parts may be interlocked together with a minimum of nailing and without requiring precise measurement or cutting as is the case with conventional building materials. This results in reduced on site waste and very accurate framing. As shown in Figure 7, a wall section may be constructed with profiled 2" x 4" studs 20 held in spaced, parallel relationship by pre-cut transverse members 22 (lock blocks) having their ends shaped to fit into the grooves of the profiled lumbers, thereby reducing the nailing requirements 67~
-to a minimum. The transverse members 22 are simply placed between adjacent studs therebv fixing the distance between the studs precisely in accordance with building industry regulations. As also shown in Figure 7, transverse mem~ers 24 of different standardized lengths may be provided to fix precisely the spacing of windows or doors, according to building industry regulations. Similarly, pre-cut transverse members 26 may be provided for fixing the spacing of profiled 2" x 10" floor beams or joists 28. The above system permits unskilled workers to assemble the framework for s-tructures strongly and accurately without having to cut or measure material.
The concept is applicable to other frame construction indu6tries including, but not limited to, mobile homes, recreational vehicles and industrial housing.
The profiled lumber may have holes pre-cut where appropriate for plumbing and wiring applications.
