Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a joining structure of a channel member 2 according to an embodiment.
As shown in FIG. 2, the groove member 2 includes a substrate portion 4, a first side plate portion 6 and a second side plate portion 7 that rise at right angles from the left and right sides of the substrate portion 4 in the same direction. This is a U-shaped cross-section having a cross-section.

  The groove-shaped member 2 is formed by bending a lightweight steel plate (here, a thickness of 0.5 mm) by pressing, but is also formed by extruding a lightweight metal such as aluminum or molding a synthetic resin. be able to.

  At the end of the first side plate portion 6 of the groove shape member 2, an engagement piece portion 8 whose cross section is bent inwardly and in a U shape is formed, and the second side plate portion 7 has the substrate portion 4. An engaging groove 10 having a concave cross section is formed in the vicinity. Further, a bent portion 11 bent inward in an L shape is formed at the distal end portion of the second side plate portion 7 to reinforce the second side plate portion 7.

The engaging piece portion 8 has an engaging piece 12 bent in a U shape, and a U-shaped groove portion 13 is formed by the engaging piece 12 and the first side plate portion 6. The width (S1) of the groove 13 is 1 mm.
The engaging groove portion 10 is formed by bending a portion of the second side plate portion 7 in the vicinity of the boundary between the substrate portion 4 and the second side plate portion 7 into an inner concave shape.

  More specifically, as shown in FIG. 2, the engaging groove portion 10 folds the end portion of the substrate portion 4 inward to form a first folded portion 14, and further in a direction parallel to the second side plate portion 7. The first groove plate portion 16 is formed by bending. Then, the first groove plate portion 16 is bent into a U-shape, and a second groove plate portion 17 that comes into contact with the second side plate portion 7 later is formed. A bent groove portion 18 is formed between the groove plate portion 17 and the groove plate portion 17. The width (S2) of the bent groove 18 is 0.5 mm.

  Further, the second groove plate portion 17 is folded outward slightly before hitting the first folded portion 14 (approximately 0.5 mm) (this forms the groove opening 20), and the second groove The second side plate portion 7 in contact with the plate portion 17 is formed, and the convex portion 22 having a U-shaped cross section is formed by the second groove plate portion 17 and the second side plate portion 7. Here, the second side plate portion 7 is formed slightly inside with respect to the end portion of the first folded portion 14, and the interval (S3) is 0.5 mm which is the same as the plate thickness. With this interval (S3), the corners of the joint 24 between the groove members 2 described later are accurately formed.

The groove shape member 2 has such a shape that the engagement piece 12 of the engagement piece portion 8 of the other groove shape member 2 can be fitted into the bent groove portion 18 and the groove opening portion 20 forming the engagement groove portion 10. Moreover, it has the shape which can fit the groove-shaped part 13 of the engagement piece part 8 of the other groove-shaped material 2 to the convex-shaped part 22 which forms the engagement groove part 10. FIG.
Thus, the engagement piece 8 (engagement groove 10) of the groove member 2 can be engaged (fitted) with the engagement groove 10 (engagement piece 8) of another groove member 2. is there. Note that there is almost no play between the engagement piece 8 and the engagement groove 10, but when both are engaged (fitted), the groove width of the bent groove 18 and the groove 13 is a spring of a steel plate. It can be enlarged by the action, and both are brought into close contact by this spring action.

Now, the groove member 2 is used as one long member whose length can be adjusted by joining two groove members 2 having the same shape (cross section) together.
In this case, first, facing each other so that the side plate portions 6 and 7 of the respective groove members 2 are engaged with each other, and the end portions of one groove member 2 and the end portions of the other groove member 2 are abutted. Are arranged separately in the longitudinal direction.

  Then, as shown in FIG. 3, the engagement piece portion 8 formed on the first side plate portion 6 of one channel member 2 is connected to the second side plate portion 7 of the other channel member 2. At the same time, the engaging groove portion 10 formed in the second side plate portion 7 of one groove shape member 2 is formed in the first side plate portion 6 of the other groove shape member 2. The engagement piece 8 is fitted.

Further, from the end portion of the one groove member 2, the end portion of the other groove member 2 is inserted and slid to form a joint section 24 having a rectangular cross section in which both groove members 2 overlap each other. In the joint portion 24, the first side plate portion 6 (second side plate portion 7) and the second side plate portion 7 (first side plate portion 6) are in close contact and overlap each other.
Then, by adjusting the length of the joining portion 24, a stretchable long material integrally formed by the joining structure of the groove members 2 is obtained.

When the length of the long material due to the joint structure between the groove members 2 is determined, the joint portion 24 is fixed using a fastening tool such as a screw 26. As the screw 26, for example, a self-drillable screw is used.
The screw 26 is screwed from the first side plate portion 6 of the joint portion 24 and fixed to the second side plate portion 7. The screws 26 may be used on the left and right sides of the joint 24, or a plurality of screws 26 may be used on one side of the joint 24. By fixing the joint portion 24 by this screwing, the length of the long material is fixed, and the strength of the joint portion 24 is reinforced. In addition, the joining part 24 can also be fixed using an adhesive.

The engagement piece 8 has a U-shaped cross section here, but other shapes can be adopted.
For example, as shown in FIG. 4, the engagement piece 12 is bent at an acute angle with respect to the first side plate portion 6 (FIG. 4A), and the engagement piece 12 is bent inwardly to form an engagement piece. The shape (FIGS. 4B and 4C) in which the distal end portion of 12 is located on the side of the substrate portion 4 with respect to the bending apex (the position farthest from the substrate portion 4) of the engagement piece 12, or It is good also as a shape etc. (FIG.4 (d) (e)) which bent the inner side, and also the middle to the front-end | tip part.
In short, the engagement piece 12 is bent at an acute angle, or the engagement piece 12 itself is bent.
In this case, the bent groove portion 18 of the engagement groove portion 10 is formed in a shape along the shape of the engagement piece 12 so that the engagement piece 12 is in close contact with the bent groove portion 18.
In this way, by forming the engagement piece portion 8 (engagement groove portion 10), when the groove members 2 are joined as described above, the groove members 2 may come off in directions other than the longitudinal direction. Absent.

Moreover, although the said groove shape joining structure is comprised by joining the two groove shape materials 2, you may join and use the 3 or more groove shape materials 2 besides.
The groove member 2 is shipped after being adjusted to a predetermined (standard) length in a factory. Usually, the channel is adjusted to a length slightly longer than half the length required at the site (for the joint).
The joint structure of the above-mentioned groove shape material is a partition material in a building, a stud as a wall base material, a field edge material as a ceiling base material, a field edge receiving material, a joist as a floor base material, and a large pulling material Etc. are available.

FIG. 5 shows a form in which a stretchable long material having a grooved material joining structure is used as a stud material 30 (intermediate column) for a partition material (or wall base material).
Here, the ceiling-side runner material 32 is disposed on the ceiling side of the room, and the floor-side runner material 34 is disposed on the floor surface side. Each of these runner materials has a groove portion having a U-shaped cross section, and the above-mentioned stretchable long material is disposed between the upper and lower runner materials.

In this case, the two channel members 2 are joined to form the stud material 30, adjusted to the required length, and the screw 26 is fixed to the joint 24 to fix the length.
Then, the end portions of the stud material 30 are fitted into the groove portions of the upper and lower runner materials, and the end portions of the stud material 30 and the runner materials are fixed with screws 26. Further, an anti-vibration material 36 is installed between the stud materials 30 as necessary. Further, a wall material 38 is attached to each stud and finished.

  The stud material for the partition material is usually prepared as a pre-cut stud material in the full length size, but when using a stretchable long material with the above-mentioned groove shape joining structure, it is slightly less than half of the full length. One kind of long channel material (substantially standard size is sufficient) may be prepared.

  In addition, when the ceiling height varies from site to site, it is necessary to prepare a stud material with a length suitable for each site. It is possible to cope by adjusting the expansion and contraction in the field only by preparing the channel material. From this, production management, inventory management, transportation and the like in the factory become easy.

  Also, for example, if there is a slight shift in the length between the upper and lower runner materials due to the unevenness of the floor foundation surface, etc., the length suitable for the location depending on the location where each stud material is placed It is sufficient to create a stud material of the length, and according to the stretchable long material, the length can be easily adjusted and fixed to a required length using a screw.

  As described above, when the stretchable long material is used as a partition material or the like, it is not necessary to adjust each time against the unevenness of the ceiling and the floor, and the construction can be simplified. Further, even in a site where the ceiling height differs by several millimeters for each level, it is not necessary to prepare studs of different dimensions, and the troublesome part management is eliminated.

FIG. 6 shows a form in which the stretchable long material by the grooved material joining structure is used for the field material 40 as a ceiling base material.
Here, the runner material 44 is disposed horizontally on the upper surface of the wall surface 42 (and the opposite wall surface), and the field material 40 is attached between both runners. Here, two (or three or more) channel members 2 are joined to form the field material 40, adjusted to the required length, and the screw 26 is fixed to the joint 24 to increase the length. Fix it. The field material 40 is installed between the runner materials 44. In addition, a ceiling board is attached to each edge material 40 and finished.

  Even in this case, normally, the edge material precut to the full length size is prepared, or the edge materials are joined to each other using the connection fitting, but when using the stretchable long material, What is necessary is just to prepare one kind of channel shape material a little longer than half of the full length.

  In general, the field margin is determined by the internal dimension of the wall. For example, the field margin varies by several mm depending on whether or not a gypsum board is stretched in the wall. In this case, by using the stretchable long material, there is no need to separate the field edge with respect to the difference of several millimeters, and simplification can be achieved in production, inventory, delivery form, and construction.

  In addition, when the distance between the wall surfaces (between the runner materials) is different at each site, it is necessary to prepare a margin material with a length corresponding to each site. It is possible to cope with any site by adjusting the expansion and contraction only by preparing the channel material of various lengths.

FIG. 7 shows a form in which a stretchable long material with the above-mentioned groove shape joining structure is used for a field edge receiving material 50 as a ceiling base material.
Here, the hanger 52 is suspended from a ceiling beam or the like at a predetermined interval, and the field edge receiving member 50 is attached thereto. Here, two (or three or more) channel members 2 are joined together to form the edge receiving member 50, adjusted to the required length, and the screw 26 is fixed to the joint 24 to obtain the length. To fix.

Then, the field edge receiving material 50 is installed on the receiving portion of the hanger 52. A field edge material 54 is arranged in a direction perpendicular to the lower edge of the field edge receiving material 50, and the field edge material 54 is attached to the field edge receiving material 50 using a clip 56. Further, a ceiling board 58 is attached to each field edge material 54 and finished.
Even in this case, the same effect as the case of the field material 40 can be obtained by using the stretchable long material.

  Therefore, according to the above embodiment, since the length of the groove shape material can be adjusted, it is not necessary to prepare different length groove shape materials for each site, and when there is a design change etc. at the site. However, the length can be changed freely and it is very convenient. Also, in manufacturing at the factory, it is not necessary to manufacture channel profiles with different lengths, making it possible to unify the lengths, reducing manufacturing costs, and storing with a shorter length when stored in a warehouse. Therefore, there is an effect that space is not required and the transportation cost is reduced.

FIG. 8 shows the joint structure of the channel member 62 according to another embodiment.
As shown in FIG. 9, the groove-shaped member 62 includes a substrate portion 64, a first side plate portion 66 that rises at right angles from the left and right sides of the substrate portion 64 in the same direction, and a second side plate portion 67. This is a U-shaped cross-section having a cross-section.

  The groove member 62 is formed by bending a lightweight steel plate (here, a thickness of 0.5 mm) by pressing, but is also formed by extruding a lightweight metal such as aluminum or molding a synthetic resin. be able to.

  At the end portion of the first side plate portion 66 of the groove member 62, an engagement piece portion 68 whose cross section is bent inwardly and in a U shape is formed, and the second side plate portion 67, the substrate portion 64, An engagement protrusion 70 having a convex cross section is formed at a portion where the crosses. Further, a bent portion 71 bent inward in an L shape is formed at the tip of the second side plate portion 67 to reinforce the second side plate portion 67.

The engagement piece portion 68 has an engagement piece 72 bent in a U shape, and a U-shaped groove portion 73 is formed by the engagement piece 72 and the first side plate portion 66. The width of the groove 73 is 1 mm.
The engaging protrusion 70 projects the end of the second side plate portion 67 outward along the second side plate portion 67 at the boundary where the substrate portion 64 and the second side plate portion 67 intersect. It is formed in a protruding shape.

  More specifically, the engagement protrusion 70 extends straight from the end of the second side plate 67 (the portion where the substrate 64 intersects), and then turns the tip back to the inside (substrate 64 side). Thus, the folded portion 74 is formed, and further bent at a right angle to continue to the substrate portion 64. The folded portion 74 is folded into a crimped shape with no gap, and therefore the thickness of the engaging projection 70 is 1 mm.

The groove member 62 has a shape in which the groove portion 73 of the engagement piece 68 of the other groove member 62 can be fitted to the engagement protrusion 70.
Thus, the engagement piece 68 (engagement protrusion 70) of the groove member 62 is engaged (fitted) with the engagement protrusion 70 (engagement piece 68) of the other groove member 62. Is possible. Although there is almost no play between the engagement piece 68 and the engagement projection 70, the groove width of the groove 73 is increased by the spring action of the steel plate when both engage (fit). It is possible, and both are brought into close contact by this spring action.

Now, the groove member 62 is used as one long member whose length can be adjusted by joining two groove members 62 having the same shape (cross section).
In this case, first, facing each other so that the side plate portions 66 and 67 of the respective groove members 62 are engaged with each other, and the ends of one groove member 62 and the ends of the other groove member 62 are abutted. Are arranged separately in the longitudinal direction.

  Then, as shown in FIG. 8, the groove-shaped portion 73 of the engaging piece portion 68 formed on the first side plate portion 66 of one groove-shaped member 62 is replaced with the second side plate portion 67 of the other groove-shaped member 62. At the same time, the engaging protrusion 70 formed on the second side plate 67 of the one groove member 62 is inserted into the first protrusion of the other groove member 62. It is inserted into the groove-like portion 73 of the engaging piece portion 68 formed on the side plate portion 66.

Further, from the end portion of the one groove member 62, the end portion of the other groove member 62 is inserted and slid to form the joint portion 24 having a rectangular cross section in which the two groove members 62 overlap each other. In the joint portion 24, the first side plate portion 66 (second side plate portion 67) and the second side plate portion 67 (first side plate portion 66) are in close contact and overlap each other.
Then, by adjusting the length of the joint portion 24, a stretchable long material integrally formed by the joint structure of the groove members 62 is obtained.

  When the length of the long material due to the joining structure of the groove members 2 is determined, the joint 24 is fixed using a fastening tool such as a screw 26 as in the above embodiment. As the screw 26, for example, a self-drillable screw is used.

The engaging piece portion 68 has a U-shaped cross section here, but this is also a shape in which the engaging piece 72 is bent at an acute angle with respect to the first side plate portion 66 or the engaging piece 72 is inward. It is good also as a shape etc. bent in the shape of a bowl (similar to the above-mentioned engagement piece part 8).
In this case, the engaging protrusion 70 is formed in a shape (such as having a bending angle) along the shape of the groove 73 of the engagement piece 72, and the groove 73 of the engagement piece 72 is engaged. It is formed so as to be in close contact with the protrusion 70.
In this manner, by forming the engagement piece portion 68 (engagement protrusion 70), when the groove members 2 are joined as described above, the groove members 62 come off in directions other than the longitudinal direction. There is nothing.

In addition, although the above-described groove-shaped member bonding structure is configured by bonding two groove-shaped members 62, three or more groove-shaped members 62 may be bonded and used.
The groove member 62 is shipped after being adjusted to a predetermined (standard) length in a factory. Usually, the channel is adjusted to a length slightly longer than half the length required at the site (for the joint).

The joint structure of the above-mentioned groove shape material is a partition material in a building, a stud as a wall base material, a field edge material as a ceiling base material, a field edge receiving material, a joist as a floor base material, and a large pulling material Etc. are available.
The specific form of use is the same as that illustrated and described in the above embodiment (stud material, field edge material, field edge receiving material).
In addition, as with the above embodiment, there is no need to prepare different lengths of groove shape materials for each site, and the effects of this embodiment can be freely changed even if there is a design change at the site. The length can be changed and it is convenient, and it is not necessary to manufacture different lengths of channel material, so the length can be unified, reducing the manufacturing cost, and the length when stored in a warehouse. Since the storage space can be shortened, there is an effect that space is not required and the transportation cost is reduced.
