<Embodiment>
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or corresponding parts. The present invention is not limited to these embodiments as will be apparent from the following description, and various modifications can be made by those skilled in the art within the scope of the gist of the invention.

<Overall structure of ground structure 1>
First, an example of the base structure 1 of a suspended ceiling to which the clip reinforcing metal fitting 8 according to the embodiment of the present invention is applied will be generally described. As shown in FIG. 1, the suspended ceiling foundation structure 1 includes a suspension bolt 2 that hangs down from a ceiling housing (not shown), and a C-shaped cross-section field edge that is connected to the suspension bolt 2 via a hanger 3. A device having a receiver 4 and a field edge 5 having a concave cross section connected to the field edge receiver 4 via a clip 6 is widely used.

  FIG. 1 shows an example in which a narrow single field edge 5a and a wide double field edge 5b are used in combination as the field edge 5, and accordingly, the field edge receiver 4 and the single field edge 5b are combined. As for the clip 6 that connects the edge 5a or the double field edge 5b, a single clip 6a and a double clip 6b are used in accordance with them. Moreover, although the case where the brace 7 is further added is shown here in order to improve seismic resistance, the setting of the brace 7 is arbitrary in this embodiment. For finishing the suspended ceiling, a ceiling finish plate (not shown) is attached to the field edge 5 of the foundation structure 1.

<Hanging bolt 2>
Hereinafter, each component of the foundation structure 1 will be described more specifically. First, the plurality of suspension bolts 2 hang from the ceiling casing at a predetermined interval, and a U-shaped hanger 3 is attached to the lower end thereof. The hanger 3 is for supporting the field receiver 4, and the field receiver 4 is arrange | positioned in the state extended mutually parallel and horizontally. Here, the suspension bolt 2 has an arrangement interval in the direction orthogonal to the field receiver 4 of about 900 mm to 1000 mm, preferably 910 mm, and the arrangement interval in the direction parallel to the field receiver 4 is also about 900 mm to 1000 mm, preferably Is 910 mm.

  The suspension bolt 2 is firmly attached to the ceiling frame using a known construction method. For example, the suspension bolt 2 is fixed by screwing about 10 to 20 mm into an insert provided on the ceiling frame. The insert is made of steel that is placed at the time of assembling the ceiling casing and embedded in the concrete, and is subjected to rust prevention treatment. As the suspension bolt 2, a known one can be used, but a spiral one may also be used. The spiral specification suspension bolt 2 has a groove engraved on its surface in a spiral shape. By engraving the spiral groove, the weight of the suspension bolt 2 is reduced and its rigidity is maintained or Can be improved. The width, depth, pitch, or number of engravings of the grooves can be appropriately set according to the strength required for the foundation structure 1 of the suspended ceiling.

  In addition, when the length of the suspension bolt 2 is longer than 1500 mm, in other words, when the height of the ceiling is 1500 mm or more, horizontal reinforcement is provided at a position between the suspension bolt 2 and within 1500 mm from the ceiling casing A. Material may be added. Furthermore, if necessary, it can be reinforced with braces.

<Hanger 3>
The hanger 3 is temporarily installed at the lower end of the suspension bolt 2 with a nut in advance, and the height direction is adjusted and fixed when the field receiver 4 is attached. FIG. 1 shows a case where a U-shaped or J-shaped hanger 3 having a cross-sectional shape that can adjust the position in the horizontal direction in addition to the height direction is used. However, the present invention is not limited to this. Never happen. In addition, for example, a hanger 3 that is divided into two parts, that is, a suspension bolt 2 side and a field edge receiver 4 side, and both of them are screwed may be used. The hanger 3 configured as described above can follow the gradient when the ceiling frame has a gradient.

<Field match 4>
The field edge receiver 4 is a member for connecting the field edge 5, and both are connected by a clip 6 at the intersection with the field edge 5. In this example, the field receiver 4 has a C-shaped cross section. However, in applying the present embodiment, it may have another cross section. . For example, it may have a square cross section. In the case of a square cross section, there is an advantage that the strength against bending and twisting can be increased as compared with a member having a C-shaped cross section. This is because by adopting a rectangular cross section, it becomes possible to improve the cross-sectional performance such as the secondary moment of section and the section modulus. As for the cross section of the field edge receiver 4, the same effect can be obtained by using, for example, a member having an E-shaped cross section in addition to the rectangular one. As described above, the cross section of the field edge receiver 4 may be C-shaped, rectangular, or E-shaped in consideration of the installation location, cost, required earthquake resistance, and the like.

  In addition, when the field receiver 4 has a square cross section, a crimped portion formed at the time of molding is formed on one short side thereof. Arrange it to be on the ceiling frame side. Further, when it is necessary to extend the field edge receiver 4, two field edge receivers 4 are put on both ends of a field edge receiving joint (not shown) and screwed respectively.

<Field 5>
The field edge 5 is arranged to cross the field edge receiver 4 as a member for holding the ceiling finish board, and is connected to the field edge receiver 4 by a clip 6 (fixed with an adhesive or a screw). In some cases). The field edge 5 has a concave cross section, and the ceiling finish plate is fixed to the bottom surface of the field edge 5 with an adhesive or a screw. As described above, the field edge 5 includes a single field edge 5a and a double field edge 5b, which are selected in consideration of conditions such as an area necessary for contact with the ceiling finish plate.

  Note that, as the field edge 5, conventionally, a joiner that is used as a joint material or joint material for a joint portion when a finishing material is arranged on a ceiling or a wall may be employed. In that case, as will be described later, the clip reinforcing bracket 8 according to the present embodiment sandwiches the side edge 5 or both side surfaces of the joiner from the outside and the inside, respectively, so If it has, this embodiment is applicable.

<Clip 6>
Although various types of clip 6 are known, any type of clip 6 can be used as long as it can connect the field edge receiver 4 and the field edge 5. For example, it is reverse L-shaped before assembling (when the lower part of the long side is engaged with the field edge 5 and the lateral short side is bent into the field edge receiver 4), or for wind resistance and field. It may be of any form, such as one that tightens from both sides of the edge receiver 4 (one that engages the hems on both sides with the field edge 5 and screwes the upper part with screws).
