The longitudinal supports and the spacer blocks include cooperating tongue and groove elements that are maintained together with an adhesive.
Description
TITLE OF THE INVENTION
SPACED COMPRESSION MEMBER
FIELD OF THE INVENTION
The present invention relates to compression members which are used in the construction of walls such as partition walls and supporting walls. The present invention also relates to a method of dorming such spaced compression members.
BACKGROUND OF THE INVENTION
Compression members, also known as spaced compression members, consist of two individual, generally vertical, supports that are joined with spacer blocks, including end blocks and intermediate blocks, which are vertically spaced apart from one another to define openings allowing the passage of electrical wire and plumbing between the members.
The connection of the spacer blocks to the individual supports is accomplished either by gluing or fastening (screws or nails); in some cases, the connection is accomplished by means of a metallic plate which surround and are secured to the parts to be connected.
However, it has been found that presently used spaced compression members with jointed or glued connectors lack in compression strength as a result of the particular type of connection used. The typical compression members are therefore not suitable for use in a structural position where they must, for example, support a portion of a roof of a building.
Another drawback of some of the presently available spaced compression members arises from the use of the so called "green wood"
to form the individual members that are relatively thin. Indeed, the individual members made of green wood often suffer deformation when the wood dries.
OBJECTS AND STATEMENT OF THE INVENTION
It is an object of the present invention to overcome the above-noted problems with respect to presently available compression members. This is achieved by providing an improved connection arrangement between the individual supports and the spacer blocks.
More specifically, according to the present invention, there is provided a compression member comprising:
a first longitudinal support including an inner face provided with tongue and groove elements;
a plurality of spacer blocks; each spacer block including first and second opposite lateral sides provided with respective tongue and groove elements; the first lateral side of each spacer block being so mounted to the inner face of the first longitudinal support that the tongue and groove elements of the first lateral sides of each spacer block are interconnected to the tongue and groove elements of the first longitudinal support; and a second longitudinal support including an inner side provided with tongue and groove elements; the second longitudinal support being so mounted to the second lateral side of each of the spacer block that the tongue and groove elements of the second lateral sides of each spacer block are interconnected to the tongue and groove elements of the second longitudinal support.
According to another aspect of the present invention, there is provided a method for making a compression member comprising the steps of:
a) providing a first longitudinal stud having a pair of opposite faces;
b) forming longitudinal tongue and groove elements on each opposite faces;
c) longitudinally cutting the first longitudinal stud to first and second longitudinal supports, each longitudinal support having an inner face provided with the tongue and groove elements;
d) providing a second longitudinal stud having a pair of opposite faces;
e) forming longitudinal tongue and groove elements on each opposite faces of the second longitudinal stud;
f) transversally cutting the second longitudinal stud in a plurality of spacer blocks;
g) applying an adhesive onto the tongue and groove elements of at least one of the (I) one of the opposite faces of the spacer blocks, and (Il) the first longitudinal support;
h) applying an adhesive onto the tongue and groove elements of at least one of the (I) the other of the opposite faces of the spacer blocks, and (Il) the second longitudinal support;
i) joining the inner face of the first longitudinal support to one of the opposite faces of each spacer block; and j) joining the inner face of the second longitudinal support to the other of the opposite faces of each spacer block.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood however that this detailed description, while indicating a preferred embodiment of the invention, is given by way of illustration only since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to Figure 1 of the appended drawings, there is shown a conventional spaced compression member, generally denoted 10, forming part of the prior art of the present invention. The spaced compression member 10 includes a pair of longitudinal support members 12 and 14 which are horizontally spaced from one another by means of a series of spacer blocks consisting of a pair of end blocks 16 and 18 and of a plurality of intermediate blocks 20 (four being shown in Figure 1).
The spacer blocks are vertically spaced from one another so as to define open spaces 22 which, when present in a partition wall, allow passage of electrical wiring and/or plumbing conduits (not shown) therethrough.
At present, the manner of joining the spacer blocks to the longitudinal supports is either by fastening means, such as screws or nails (not shown) driven through the longitudinal supports 12, 14 into the spacer blocks; or by an adhesive provided between the longitudinal supports 12, 14 and the spacer blocks. In some cases, a metallic plate (not shown) surrounds the spacer blocks and the longitudinal supports, the plate being nailed or otherwise secured to both the longitudinal supports and the spacer blocks.
Referring now to Figure 2 of the appended drawings, a spaced compression member, generally denoted 30, according to an embodiment of the present invention will be described. The spaced compression member 30 includes a pair of longitudinal supports 32 and 34 which are mounted to one another in a spaced relationship by spacer blocks, such as end blocks 36, 37 and intermediate blocks 38 (only one shown).
Turning to Figures 3 and 4, each longitudinal support 32, 34 may advantageously be formed of a series of wood studs, for example 32a and 32b in Figure 3. These supports are jointed at their facing ends by means of angled tongue and groove elements 40 and 42. As can be better seen from Figure 4, the angle a of the tongue and groove elements 40 and 42 is preferably about 5 degrees. Of course, an adhesive, such as, for example, resorcinol or phenol-resorcinol resin, is provided between the wood studs 32a and 32b to adequately maintain these studs together.
This type of end to end wood joint is believed well known to those skilled in the art. Accordingly, this joint will not be described further, for conclsion purposes.
Referring now to Figures 5 and 6 of the appended drawings, the interconnection of the spacer blocks 36 with the longitudinal supports 32 and 34 will now be described in greater details. As can be seen from this figure, each of the inner faces 43 and 44 of respective longitudinal supports 32 and 34 include five round tongue and groove elements.
Similarly, each of the opposite faces 46 and 48 of the spacer block 36 are provided with five round tongue and groove elements that are configured and sized to respectively engage the round tongue and groove elements of the inner faces 43 and 44 of the longitudinal supports 32 and 34.
Figure 6 shows the supports 32, 34 and the spacer block 36 after the interconnection of the pairs of inner faces 43, 46 and 44, 48 to form respective tongue and groove interconnected arrangements 50 and 52.
Of course, as mentioned hereinabove, an adhesive, such as, for example, resorcinol or phenol-resorcinol resin, is provided between the interconnecting faces to adequately secure the tongue and groove interconnected arrangements 50 and 52.
As will be understood by one skilled in the art, all the elements of the spaced compression member are made of wood, which may be pieces of spruce, pine and/or fir wood. Advantageously, it has been found that black spruce, also known as eastern spruce, is particularly well suited for the construction of the spaced compression members 30 of the present invention since it is a relatively dense softwood.
It has been found advantageous to use relatively small pieces of wood, for example, pieces of black spruce smaller than 18 inches (~460 mm) long to form the spaced compression member of the present invention. Indeed, as will be understood by one of ordinary skilled in the art, these relatively small pieces of wood may be recuperated from lumber usually thrown away. This presents two major advantages: the recuperation of small pieces of lumber that are usually thrown away and the construction of compression members that are less prone to distortion under adverse temperature and/or humidity conditions.
Another advantage of the present invention is that the pieces of wood used to form the compression members according to the present invention are upgraded since the weak or otherwise defective portions, for example bods, are eliminated before the members are jointed end to end (see Figure 3) and kiln-dried to about 15% or less humidity. A
stronger structural piece of wood results since nearly all possibility of wood distorsion is eliminated.
The following table (Table 1) illustrates some of the dimensions of spaced compression members that have been found adequate. The first example generally has the dimensions of a conventional 2X4 inches, 8 foot long stud while the second example generally has the dimensions of a conventional 2X6 inches,12 foot long stud.

The various steps of this method are illustrated in Figures 7-11 and will now be described.
A first piece of lumber (see stud 100 in Figure 7) has its opposite faces 102 and 104 machined to have the round tongue and groove configuration respectively illustrated as 106 and 108 in Figure 8.
As will be easily understood by one skilled in the art, power tools such as, for example, a shaper provided with an appropriate cutting element (not shown) may be used to machine the round tongue and groove elements in the opposite faces 102 and 104. As mentioned hereinabove, the stud 100 may be made of recycled relatively small pieces of wood glued end to end.
The piece of lumber is longitudinally cut along line 110 (Figure 9) to form two distinct supports 112 and 114.
A second piece of lumber similar to stud 100 also has its opposite faces machined to present the round tongue and groove elements shown in Figure 8. This second piece of lumber is transversally cut to yield a plurality of spacer blocks 116 (Figure 10) having a predetermined length.
A coating of adhesive (not shown) is then applied to the round tongue and groove elements of the longitudinal supports 112,114 and/or to the round tongue and groove elements of the spacer blocks 116.
The spacer blocks 116 are then positioned between the two longitudinal supports 112 and 114 (Figure 10) at predetermined positions to form a spaced compression member having the required strength properties, while providing spaces between consecutive spacer blocks.
The round tongue and groove elements of the spacer blocks 1 16 are then brought into contact with the respective round tongue and groove elements of the longitudinal supports 112 and 114.
Finally, the assembly of the two longitudinal supports 1 12 and 114 with a series of intermediate blocks 116 is accomplished by applying pressure on the outside of the supports, as indicated by arrows 120 and 122 in Figure 11. It is to be noted that the pressure applying step may not be required, depending on the type of adhesive used.
It is to be noted that the above-described method may be followed for any conventional length of spaced compression members.
As will be easily understood by one skilled in the art, the use of round tongue and groove elements for joining the longitudinal supports 112 and 114 to the spacer blocks 116 has many advantages. For example, the round tongue and groove element increase the gluing area between the wood pieces. The round tongue and groove elements also minimize the number of reject pieces due to wood breakage during assembly. Indeed, since the round tongue and groove elements do not have long sharp edges, the breakage rate is low even when the positioning of the mating tongue and groove elements is not perfect since the round tongue and groove elements provide automatic positioning.
Of course, as will be already known to those skilled in the art, if spaced compression members according to the present invention are used to erect supporting walls, they must be approved by competent authorities.
Although the invention has been described with respect to one specific form, it will be evident to the person skilled in the art that it may be refined and modified in various ways. It is therefore wished to have it understood that the present invention should not be limited in interpretation, except by the terms of the following claims.
SPACED COMPRESSION MEMBER
FIELD OF THE INVENTION
The present invention relates to compression members which are used in the construction of walls such as partition walls and supporting walls. The present invention also relates to a method of dorming such spaced compression members.
BACKGROUND OF THE INVENTION
Compression members, also known as spaced compression members, consist of two individual, generally vertical, supports that are joined with spacer blocks, including end blocks and intermediate blocks, which are vertically spaced apart from one another to define openings allowing the passage of electrical wire and plumbing between the members.
The connection of the spacer blocks to the individual supports is accomplished either by gluing or fastening (screws or nails); in some cases, the connection is accomplished by means of a metallic plate which surround and are secured to the parts to be connected.
However, it has been found that presently used spaced compression members with jointed or glued connectors lack in compression strength as a result of the particular type of connection used. The typical compression members are therefore not suitable for use in a structural position where they must, for example, support a portion of a roof of a building.
Another drawback of some of the presently available spaced compression members arises from the use of the so called "green wood"
to form the individual members that are relatively thin. Indeed, the individual members made of green wood often suffer deformation when the wood dries.

According to another aspect of the present invention, there is provided a method for making a compression member comprising the steps of:
a) providing a first longitudinal stud having a pair of opposite faces;

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to Figure 1 of the appended drawings, there is shown a conventional spaced compression member, generally denoted 10, forming part of the prior art of the present invention. The spaced compression member 10 includes a pair of longitudinal support members 12 and 14 which are horizontally spaced from one another by means of a series of spacer blocks consisting of a pair of end blocks 16 and 18 and of a plurality of intermediate blocks 20 (four being shown in Figure 1).
The spacer blocks are vertically spaced from one another so as to define open spaces 22 which, when present in a partition wall, allow passage of electrical wiring and/or plumbing conduits (not shown) therethrough.
At present, the manner of joining the spacer blocks to the longitudinal supports is either by fastening means, such as screws or nails (not shown) driven through the longitudinal supports 12, 14 into the spacer blocks; or by an adhesive provided between the longitudinal supports 12, 14 and the spacer blocks. In some cases, a metallic plate (not shown) surrounds the spacer blocks and the longitudinal supports, the plate being nailed or otherwise secured to both the longitudinal supports and the spacer blocks.
Referring now to Figure 2 of the appended drawings, a spaced compression member, generally denoted 30, according to an embodiment of the present invention will be described. The spaced compression member 30 includes a pair of longitudinal supports 32 and 34 which are mounted to one another in a spaced relationship by spacer blocks, such as end blocks 36, 37 and intermediate blocks 38 (only one shown).
Turning to Figures 3 and 4, each longitudinal support 32, 34 may advantageously be formed of a series of wood studs, for example 32a and 32b in Figure 3. These supports are jointed at their facing ends by means of angled tongue and groove elements 40 and 42. As can be better seen from Figure 4, the angle a of the tongue and groove elements 40 and 42 is preferably about 5 degrees. Of course, an adhesive, such as, for example, resorcinol or phenol-resorcinol resin, is provided between the wood studs 32a and 32b to adequately maintain these studs together.
This type of end to end wood joint is believed well known to those skilled in the art. Accordingly, this joint will not be described further, for conclsion purposes.
Referring now to Figures 5 and 6 of the appended drawings, the interconnection of the spacer blocks 36 with the longitudinal supports 32 and 34 will now be described in greater details. As can be seen from this figure, each of the inner faces 43 and 44 of respective longitudinal supports 32 and 34 include five round tongue and groove elements.
Similarly, each of the opposite faces 46 and 48 of the spacer block 36 are provided with five round tongue and groove elements that are configured and sized to respectively engage the round tongue and groove elements of the inner faces 43 and 44 of the longitudinal supports 32 and 34.
Figure 6 shows the supports 32, 34 and the spacer block 36 after the interconnection of the pairs of inner faces 43, 46 and 44, 48 to form respective tongue and groove interconnected arrangements 50 and 52.
Of course, as mentioned hereinabove, an adhesive, such as, for example, resorcinol or phenol-resorcinol resin, is provided between the interconnecting faces to adequately secure the tongue and groove interconnected arrangements 50 and 52.
As will be understood by one skilled in the art, all the elements of the spaced compression member are made of wood, which may be pieces of spruce, pine and/or fir wood. Advantageously, it has been found that black spruce, also known as eastern spruce, is particularly well suited for the construction of the spaced compression members 30 of the present invention since it is a relatively dense softwood.
It has been found advantageous to use relatively small pieces of wood, for example, pieces of black spruce smaller than 18 inches (~460 mm) long to form the spaced compression member of the present invention. Indeed, as will be understood by one of ordinary skilled in the art, these relatively small pieces of wood may be recuperated from lumber usually thrown away. This presents two major advantages: the recuperation of small pieces of lumber that are usually thrown away and the construction of compression members that are less prone to distortion under adverse temperature and/or humidity conditions.
Another advantage of the present invention is that the pieces of wood used to form the compression members according to the present invention are upgraded since the weak or otherwise defective portions, for example bods, are eliminated before the members are jointed end to end (see Figure 3) and kiln-dried to about 15% or less humidity. A
stronger structural piece of wood results since nearly all possibility of wood distorsion is eliminated.
The following table (Table 1) illustrates some of the dimensions of spaced compression members that have been found adequate. The first example generally has the dimensions of a conventional 2X4 inches, 8 foot long stud while the second example generally has the dimensions of a conventional 2X6 inches,12 foot long stud.

The various steps of this method are illustrated in Figures 7-11 and will now be described.
A first piece of lumber (see stud 100 in Figure 7) has its opposite faces 102 and 104 machined to have the round tongue and groove configuration respectively illustrated as 106 and 108 in Figure 8.
As will be easily understood by one skilled in the art, power tools such as, for example, a shaper provided with an appropriate cutting element (not shown) may be used to machine the round tongue and groove elements in the opposite faces 102 and 104. As mentioned hereinabove, the stud 100 may be made of recycled relatively small pieces of wood glued end to end.
The piece of lumber is longitudinally cut along line 110 (Figure 9) to form two distinct supports 112 and 114.
A second piece of lumber similar to stud 100 also has its opposite faces machined to present the round tongue and groove elements shown in Figure 8. This second piece of lumber is transversally cut to yield a plurality of spacer blocks 116 (Figure 10) having a predetermined length.
A coating of adhesive (not shown) is then applied to the round tongue and groove elements of the longitudinal supports 112,114 and/or to the round tongue and groove elements of the spacer blocks 116.
The spacer blocks 116 are then positioned between the two longitudinal supports 112 and 114 (Figure 10) at predetermined positions to form a spaced compression member having the required strength properties, while providing spaces between consecutive spacer blocks.
The round tongue and groove elements of the spacer blocks 1 16 are then brought into contact with the respective round tongue and groove elements of the longitudinal supports 112 and 114.
Finally, the assembly of the two longitudinal supports 1 12 and 114 with a series of intermediate blocks 116 is accomplished by applying pressure on the outside of the supports, as indicated by arrows 120 and 122 in Figure 11. It is to be noted that the pressure applying step may not be required, depending on the type of adhesive used.
It is to be noted that the above-described method may be followed for any conventional length of spaced compression members.
As will be easily understood by one skilled in the art, the use of round tongue and groove elements for joining the longitudinal supports 112 and 114 to the spacer blocks 116 has many advantages. For example, the round tongue and groove element increase the gluing area between the wood pieces. The round tongue and groove elements also minimize the number of reject pieces due to wood breakage during assembly. Indeed, since the round tongue and groove elements do not have long sharp edges, the breakage rate is low even when the positioning of the mating tongue and groove elements is not perfect since the round tongue and groove elements provide automatic positioning.
Of course, as will be already known to those skilled in the art, if spaced compression members according to the present invention are used to erect supporting walls, they must be approved by competent authorities.
Although the invention has been described with respect to one specific form, it will be evident to the person skilled in the art that it may be refined and modified in various ways. It is therefore wished to have it understood that the present invention should not be limited in interpretation, except by the terms of the following claims.
