Field edge suspension formed via double inner side fold 12 A plate piece 8 consists, in the first and second strut mounting plate pieces 5,6, multiple screw insertion hole 9 is formed through over its entire surface.

  In addition, although the reinforcement piece 19 is formed in the upper end part of the 1st bracing attachment plate piece part 5, this may be abbreviate | omitted. The suspension bolt mounting plate piece 7 is provided with a bolt insertion hole 20 through which the suspension bolt 1 is inserted, so that the lower part of the second bracing attachment plate piece 6 and the edge receiving suspension plate piece 8 are inserted. The retaining bolt 21 (see FIG. 3) is inserted into the suspension plate piece 8 in order to prevent the field edge receiver 3 suspended from the field edge suspension plate portion 8 from coming out of the suspension plate piece portion 8. Then, bolt insertion holes 22 and 23 for screwing with the second bracing attachment plate piece 6 are provided, and the latter bolt insertion hole 23 serves as a pilot hole when the holding bolt 21 is screwed. Then, the holding bolt 21 is screwed into a bolt insertion hole 23 as a lower hole by an automatic screwing machine, thereby being engaged by threading.

  The punched metal plate 2A formed by developing the field edge metal fitting 2 shown in FIG. 1 can be bent to form the field edge metal fitting 2 for the brace 4 for steadying as shown in FIG. In addition, as will be described later, the field edge fitting 2 of the steel frame purlin 17 can be formed by bending as shown in FIG. 2 is bent in a plane L shape from the first side bracing attachment plate piece 5 and the vertical side edge of the first bracing attachment plate piece 5 so as to be attached to the first brace. A second bracing attachment plate piece 6 that faces the plate piece 5 in a plane L shape, that is, at a right angle, and a suspension bolt attachment that is formed horizontally at the upper end of the second bracing attachment plate piece 6 The first and second bracing attachment plate, comprising a plate piece portion 7 and a substantially upward U-shaped field receiving suspension plate piece portion 8 formed at the lower end of the second bracing attachment plate piece portion 6. A large number of screw insertion holes 9 are provided through the entire surfaces of the first and second bracing attachment plate pieces 5, 6 in the pieces 5, 6, and the first bracing attachment plate piece 5 A screw insertion hole 19 is also provided through the reinforcing piece 19 at the upper end and the edge receiving suspension plate piece 8, and the suspension bolt 1 is connected to the suspension bolt mounting plate piece 7. Bolt insertion holes 20 for bets stop is in the field edge receiving suspension plate piece 8 to the bolt insertion holes 22, 23 for holding bolts inserted is formed is as described above.

  As shown in FIGS. 3 and 4, the field edge suspension device has a lower end from its upper end portion between the adjacent suspension bolts 1, 1 of the suspension bolt 1 that is suspended from the ceiling portion S and anchored to the embedded insert Sa. The brace 4 for the steady rest attached to the part is provided, and as shown in FIG. 4, the upper end of the brace 4 for the steady rest is provided by the pivot fitting 13 attached to the upper end of the suspension bolt 1. The tilt angle is pivotally connected so that it can be freely displaced. The pivot fitting 13 includes a main body portion 13a locked to the upper end portion of the suspension bolt 1, a tilt portion 13c pivotally attached to the main body portion 13a by a pivot shaft 13b, and a screw hole 13d provided in the tilt portion 13c. And a connecting portion 13e such as a battledore bolt that is connected to the upper end of the brace 4 for steadying.

  The inclination angle of the bracing brace 4 arranged between the adjacent hanging bolts 1 and 1 of the hanging bolt 1 suspended from the ceiling S is 45 °. When the interval between the two is narrow, for example, it is 60 °, and when it is wide, the inclination angle is, for example, 30 °, and the bracing braces corresponding to various tilt angles of these bracing braces 4 4 needs to be attached to the upper end of the suspension bolt 1, but in the present invention, the above-mentioned pivot fitting 13 can be used sufficiently. Thus, the lower end 4a of the brace 4 for the steady rest is for the steady rest among the multiple screw insertion holes 9 provided in the first or second brace attachment plate pieces 5 and 6 of the field fitting 2.

The first and second bracing attachment plate pieces 5 and 6 of the field edge fitting 2 are provided with a lower end portion 4a of the bracing brace 4 regardless of various inclination angles of the bracing brace 4. A number of screw insertion holes 9 are provided through the entire surface of the first and second bracing attachment plate pieces 5 and 6 so as to be screwed to the first and second bracing attachment plate pieces 5 and 6. For this reason, it is possible to fix the screws corresponding to the various mounting inclination angles of the brace 4 for the steady rest.

When the bracing braces 4 are arranged at appropriate intervals in a direction orthogonal to the longitudinal direction of the field edge receiver 3, they are attached by the first brace attachment plate piece 5 of the field edge metal fitting 2. In addition, when the bracing brace 4 is arranged at an appropriate interval along the longitudinal direction of the field receiver 3, it can be attached by the second brace attachment plate piece 6 of the field receiver 2. It is possible to attach the bracing brace 4 with the common edge receiving metal fitting 2 regardless of whether the arrangement direction of the brace 4 for the steady rest is a direction perpendicular to the longitudinal direction or a direction along the longitudinal direction. Since it is not necessary to provide the dedicated field edge fitting 2 due to the difference in the arrangement direction of the bracing brace 4, the field edge receiving metal 2 can be manufactured at a lower cost and the field edge receiving metal 2 Is a kind Since consisting, it is easy because there is no need construction site to select each time the field edge receiving metal fitting its dedicated by the arrangement direction of the difference-preventing braces 4 runout.
Further, the first and second bracing attachment plate pieces 5 and 6 are provided with the lower end portion 4a of the steady brace 4 regardless of various inclination angles of the steady brace 4 and the first and second brace. Since a large number of screw insertion holes 9 are formed through the entire surface of the first and second bracing attachment plate pieces 5 and 6 so that the attachment plate pieces 5 and 6 can be screwed, the steady rest There is no need to provide a screw insertion hole for each of the various attachment inclination angles of the reinforcing bar 4, and the workability is improved accordingly.
Furthermore, since the field edge fitting 2 is composed of the first bracing attachment plate piece 5 and the second bracing attachment plate piece 6 bent at right angles thereto, the first and second bracing attachment plates. Even if a large number of screw insertion holes 9 are provided through the entire surface of the one part 5, 6, the steady-rest strength of the brace 4 for the steady-rest brace 4 with respect to the field-edge bracket 2 can be kept large. The edge receiving metal fitting 2 can be stably supported.

  In the embodiment shown in FIGS. 3 to 5, the brace 4 for steadying is arranged at an appropriate interval in a direction orthogonal to the longitudinal direction of the field receiver 3, and the first of the field receiver 2.
