A plurality of cutouts 25 are provided through the material 23 in the thickness direction. By providing each notch 25, a portion that becomes the first protrusion 7, the second protrusion 9, and the third protrusion 13 is formed.

  In addition, the site | part used as the 1st protrusion part 7 and the 2nd protrusion part 9 is formed in the longitudinal direction of the raw material 23 at predetermined intervals (for example, with a pitch of 455 mm larger than a conventional thing). The part which becomes the 3rd protrusion part 13 is provided between the part used as the 1st protrusion part 7 and the 2nd protrusion part 9.

  The material 23 provided with the notches 25 shown in FIG. 9 is bent at bending lines 11, 17, and 19, so that the main body 5, the first protrusion 7, and the second protrusion as shown in FIG. The edge receiving material 1 provided with the part 9, the 3rd protrusion part 13, and the 4th protrusion part 15 is formed. The longitudinal direction of the field edge receiving material 1 and the longitudinal direction of the main body 5 coincide with each other.

  The 1st protrusion part 7 is formed in the isosceles trapezoid shape, and the main-body part 5, the 2nd protrusion part 9, the 3rd protrusion part 13, and the 4th protrusion part 15 are formed in the rectangular shape.

  The first protrusion 7 has a lower bottom longer than the upper bottom in contact with the main body 5, and the upper bottom in contact with the second protrusion 9. The length of the second protrusion 9 (the horizontal dimension in FIGS. 9 and 10) is equal to the upper and lower dimensions of the first protrusion 7. The length of the third protrusion 13 (the horizontal dimension in FIGS. 9 and 10) is longer than the length of the first protrusion 7 and the second protrusion.

  A small rectangular cut 27 is formed at the base end (end on the main body 5 side) of the first protrusion 7. The notch 27 forms a part of the notch 25. The cuts 27 are provided in pairs at both ends of the first projecting portion 7 (both ends in the longitudinal direction of the lower bottom; both ends in the left-right direction in FIGS. 9 and 10).

  By providing the cuts 27 as a pair, the first projecting portion 7 has a smaller dimension in the length direction (dimension in the left-right direction in FIGS. 9 and 10) at the base end ( For example, it is the size of the upper base).

  As shown in FIG. 4B and the like, the cross-sectional shape of the field receiving material 1 (longitudinal direction of the field receiving material 1) at the portion where the third protrusion 13 and the fourth protrusion 15 are formed. The shape of the cross section of a plane orthogonal to the shape is a “U” shape. Note that, in the letter “U”, the protruding length L3 of the third protruding portion 13 and the protruding length L4 of the fourth protruding portion 15 are equal to each other.

  Further, as shown in FIG. 4B and the like, the cross-sectional shape of the field edge receiving material 1 is also a portion where the first projecting portion 7, the second projecting portion 9, and the fourth projecting portion 15 are formed. (The shape of a cross section by a plane orthogonal to the longitudinal direction of the field edge receiving material 1) is a "U" shape. However, in the letter “U”, the protruding length L4 of the fourth protruding portion 15 is longer than the protruding length L2 of the second protruding portion 9.

  Further, the fourth projecting portion 15 of the field edge receiving material 1 is formed with an “L” -shaped notch 31 for engaging the stud bolt 29 that supports the field edge receiving material 1 (FIG. 4 (c)).

  By the way, the field edge 3 is a standard product that has been commercially available in the past, and is formed in a shape obtained by appropriately bending a rectangular flat plate-like elongated material. The cross-sectional shape of the field edge 3 (the cross-sectional shape by a plane orthogonal to the longitudinal direction) is a “U” shape including a bottom plate portion 35 and a pair of side plate portions 37 as shown in FIG. However, a pair of locking portions 33 is formed at the opening 39 of the letter “U”. The pair of locking portions 33 slightly protrudes inside the opening 39.

  Next, the usage method of the field edge receiving material 1 is demonstrated.

  First, a plurality of (for example, two as shown in FIG. 1) field edge receiving materials 1 are suspended using stud bolts 29 and installed on a frame of a house.

  In the state in which the installation is made, the field edge receiving materials 1 are parallel to each other and extend in the horizontal direction. In the longitudinal direction and the vertical direction of the field edge receiving material 1, each field edge receiving material 1 is Located in the same place.

  Subsequently, a plurality of (5 in FIG. 1) field edges 3 are installed on each field edge receiving material 1. In the state where this installation is performed, the respective field edges 3 are parallel to each other below the field edge receiving material 1 and extend in the horizontal direction (direction perpendicular to the longitudinal direction of the field edge receiving material 1). In addition, the field edges 3 are located at the same position in the longitudinal direction and the vertical direction of the field edges 3.

  The installation of the field edge 3 on the field edge receiving material 1 will be described in more detail.

  The installation of the field edge 3 on the field edge receiving material 1 is performed so that the opening 39 of the field edge 3 is on the upper side, and the field edge 3 is connected to the protrusions 7 and 9 of the field edge receiving material 1 from below. (See FIG. 5A). As the field edge 3 rises, the pair of locking parts 33 located at the tips of the pair of side plate parts 37 of the field edge 3 come into contact with the first protrusion 7 (the isosceles trapezoidal hypotenuse). Elastically deforms. By this elastic deformation, the opening 39 of the field edge 3 is expanded (the dimension L6 is increased).

  When the field edge 3 is further raised, the field edge 3 is restored, the pair of engaging portions 33 of the field edge 3 enter the pair of cuts 27, and the field edge 3 is installed on the field edge receiving material 1 so that the field edge 3 does not fall. The At this time, the protrusions 7 and 9 of the field edge receiving material 1 enter the field edge 3, and the second protrusion 9 is in surface contact with the flat bottom plate part 35 of the field edge 3.

  Then, the 2nd protrusion part 9 of the field edge receiving material 1 and the baseplate part 35 of the field edge 3 are used for the special plate bolt 20 from the field edge 3 lower side using the special disk bolt (special machine screw). Screwed into the protruding portion 9 and the bottom plate portion 35) and fixed integrally (see FIG. 5B). The special countersunk bolt 20 has a truncated cone-shaped head, a tip portion having a drill function, and an intermediate portion having a male screw. Therefore, when fixing the 2nd protrusion part 9 of the field edge receiving material 1 and the baseplate part 35 of the field edge 3 using the special countersunk bolt 20, it is necessary to provide the hole which inserts the special countersunk bolt 20 previously. There is no. In addition, it may replace with a special countersunk | bolt bolt and you may fix the said by other fastening means, such as a normal Sarabis and a nut, a rivet, and welding.

  In any case, it is necessary to prevent a head such as a bolt from protruding downward from the lower end of the field edge 3 in FIG. It is because it will become difficult to install a ceiling board if heads, such as a bolt, protrude.

  Moreover, when fixing the 2nd protrusion part 9 of the field edge receiving material 1 and the baseplate part 35 of the field edge 3 using the special countersunk | bolt bolt 20 or Sarabis, from the lower end of the field edge 3 of FIG.5 (b). In order to prevent a head such as a bolt from protruding downward, it is desirable to apply salamomi processing to the bottom plate portion 35 of the field edge 3.

  Here, the case where the field edge 3 is supported via the clip material 21 in the site | part in which the 3rd protrusion part 13 of the field edge receiving material 1 is provided is demonstrated. Each dimension of the field edge receiving material 1 shall be the same dimension as the conventional standard goods.

  For example, the dimensions L3 and L4 shown in FIG. 4B are 37 mm, and the dimension (width of the main body 5) L5 is 38 mm.

  The clip material 21 is already standardized and generally used. As shown in FIGS. 6 and 7, a hook portion 41 and an engaging portion 43 are provided.

  In a state where the clip material 21 is installed at the portion where the third protrusion portion 13 and the fourth protrusion portion of the field edge receiving material 1 are provided, the hook portion 41 is engaged with the field edge receiving material 1. . The clip material 21 engaged with the field edge receiving material 1 slides with respect to the field edge receiving material 1 in the longitudinal direction of the field edge receiving material 1 and moves upward with respect to the field edge receiving material 1. It can be removed from the field edge receiving material 1 but is not moved with respect to the field edge receiving material 1 in other directions and is not rotated. .

  After the clip material 21 is installed on the field edge receiving material 1, the field edge 3 is installed on the clip material 21, and the field edge 3 is supported by the field edge receiving material 1 through the clip material 21.

  In addition, you may comprise the engaging part 43 of the clip material 21 similarly to what combined the 1st protrusion part 7 and the 2nd protrusion part 9 of the field edge receiving material 1. FIG. And using the special countersunk | bolt bolt 20, the field edge 3 is integrally installed in the engaging part 43 of the clip material 21, and the hook part 41 of the clip material 21 is used for the field edge receiving material 1 using the special countersunk bolt 20. You may install in one.

  After the installation of the field edge 3 is completed, a ceiling board (not shown in FIG. 1) is installed below the field edge 3. Thereby, a ceiling board is supported by the frame of a house through the field edge 3, the field edge receiving material 1, and the stud bolt 29, and the ceiling of a room is installed.

  According to the field edge receiving material 1, the second protrusion 9 is formed in the field edge receiving material 1, and when the field edge 3 is supported by the field edge receiving material 1, The bottom plate portion 35 of the edge 3 is in surface contact. In addition, the field edge receiving material 1 and the field edge 3 can be integrated by passing a fastener such as a special countersunk bolt 20 through the surface contact portion and fixing it.

  Thus, when an earthquake or the like occurs, the position of the field edge 3 with respect to the field edge receiving material 1 not only in the horizontal and vertical directions of the paper surface of FIG. 5B but also in the direction orthogonal to the paper surface of FIG. Displacement is eliminated and earthquake resistance is improved.

  Moreover, according to the field edge receiving material 1, the sum of the protrusion length L1 of the first protrusion 7 and the protrusion length of the second protrusion L2 is equal to the protrusion length L3 of the third protrusion 13. Therefore, when manufacturing the field edge receiving material 1, an excessive cut end is generated only at the portion of the notch 25, and the waste of the material can be suppressed as much as possible.

  Moreover, according to the field edge receiving material 1, since the 3rd protrusion part 13 and the 4th protrusion part 15 are provided, the cross-sectional secondary moment of the field edge receiving material 1 becomes large, and the field edge The bending rigidity and torsional rigidity of the receiving material 1 are high.

  Moreover, according to the field edge receiving material 1, in the site | part in which the 3rd protrusion part 13 of the field edge receiving material 1 is provided, the field edge 3 is supported via the clip material 21. In order to avoid interference with lighting or the like installed on the ceiling, the installation position of the field edge 3 with respect to the field edge receiving material 1 must be shifted, and this can be handled flexibly.

  The above-mentioned field edge receiving material 1 is formed integrally with the main body part extending in the horizontal direction and the main body part, protrudes downward from the lower part of the main body part, and engages with the field edge to integrate the field edge. A field having a downward projecting portion (supporting so that the field edge does not fall under the weight of the field edge and supporting the field edge integrally with the field edge so that the field edge does not move horizontally) It is an example of an edge receiving material.
