  When multiple types of metal fittings exist, the following problems occur. First, depending on whether the beam is an H-shaped beam or a C-shaped beam, the trouble of searching for a corresponding metal fitting occurs. Further, the mounting procedure and the mounting angle for the beam and the field receiver are different between the H-shaped beam bracket and the C-shaped beam bracket. For this reason, for example, when the H-beam bracket and the C-beam bracket are simultaneously mounted on the same edge receiver, a different mounting procedure is required, or the bracket is mounted at an unreasonable mounting angle. The case where the attachment is performed occurs. That is, it is difficult to attach the metal fitting. Furthermore, since it is necessary to prepare a plurality of types of metal fittings, it is difficult to suppress the manufacturing cost of the building including the inventory management of the metal fittings.

  This invention is made | formed in view of the situation mentioned above, The objective is to provide the ceiling hanging bracket which can prevent the attachment operation | work to a beam and a field edge holder becoming difficult.

  According to the above configuration, since the second plate-like portion has the first groove and the second groove, the flanges of the H-shaped beam and the C-shaped beam can be inserted into the first groove, and the lip of the C-shaped beam is the first lip. It can be inserted into two grooves. Therefore, the ceiling hanging bracket according to the above configuration can be fixed to either the H-shaped beam or the C-shaped beam. Since it is not necessary to coexist with the ceiling hanging bracket for the H-shaped beam and the ceiling hanging bracket for the C-shaped beam, the installation work of the ceiling hanging bracket is prevented from being complicated.

  (2) Preferably, the first groove is formed beyond the second groove by a predetermined distance in the first direction, and the shape of the first groove and the second groove is a T-shape. is there.

  According to the above configuration, since the first groove is formed beyond the second groove by a predetermined distance in the first direction, the position where the end face of the flange of the H-shaped beam abuts the first groove; The position where the surface of the lip of the C-shaped beam hits the second groove is different. Therefore, when the same field receiver is supported by the H-shaped beam and the C-shaped beam arranged in series via the ceiling hanger, the end surface of the lip of the C-shaped beam is separated from the end surface of the flange of the H-shaped beam. Even so, by setting the predetermined distance according to the separation distance, the edge receiver can be supported by both the H-shaped beam and the C-shaped beam without difficulty by the same type of ceiling hanging bracket.

  (3) The frame structure of the multi-story building according to the present invention includes an uppermost structure portion that supports the ceiling base material on the top floor, and an intermediate structure portion that supports the ceiling base material on the other floor other than the top floor, The uppermost structure portion includes an H-shaped beam having a flange, a C-shaped beam fixed to the H-shaped beam and having a flange and a lip, the H-shaped beam, and the above-described structure.

  With reference to FIG. 14, FIG. 15, the structure part in which the H-shaped beam 21 and the C-shaped beam 22 are arrange | positioned in series in a 1st intermediate structure part is demonstrated.

  The first intermediate structure portion has a plurality of H-shaped beams 21, and includes a structure portion in which one H-shaped beam 21 and another H-shaped beam 21 are fixed orthogonally. Further, as described above, the C-shaped beam 22 is fixed orthogonally to any one of the H-shaped beams. Therefore, as shown in FIG. 14, the first intermediate structure portion includes a structure portion in which an H-shaped beam 21 and a C-shaped beam 22 are arranged in series.

  FIG. 14 shows a case where the same field receiver 24 is supported by both the H-shaped beam 21 and the C-shaped beam 22 in the structural portion in which the H-shaped beam 21 and the C-shaped beam 22 are arranged in series. ing.

The separation distance 102 is a separation distance between the end face of the lip 63 of the C-shaped beam 22 in the first horizontal direction 8 and the end face of the flange 26 of the H-shaped beam 21 in the first horizontal direction 8. In the present embodiment, the separation distance 102 is the same as the predetermined distance 101 in which the horizontal groove 48 exceeds the vertical groove 49 in the first horizontal direction 8. The separation distance 102 may be smaller than the predetermined distance 101.

[Operational effects of this embodiment]
According to the multi-storey building frame structure 100 according to the present embodiment, since the vertical portion 44 has the horizontal groove 48 and the vertical groove 49, the flange 26 of the H-shaped beam 21 and the flange 58 and the lip 63 of the C-shaped beam 22 are provided. It can be inserted into the horizontal groove 48, and the lip 63 of the C-shaped beam 22 can be inserted into the vertical groove 49. Therefore, the intermediate ceiling hanger 23 can be fixed to either the H-shaped beam 21 or the C-shaped beam 22. Similarly, since the first vertical portion 69 and the second vertical portion 70 have a horizontal groove 75 and a vertical groove 76, respectively, the uppermost ceiling hanging bracket 64 can be fixed to either the H-shaped beam 21 or the C-shaped beam 22. is there. Since there is no need to co-exist with the H-beam intermediate ceiling bracket 23 and the C-beam intermediate ceiling bracket 23, the installation work of the ceiling bracket is prevented from being complicated. Similarly, it is not necessary to coexist the uppermost ceiling hanging bracket 64 for the H-shaped beam and the uppermost ceiling hanging bracket 64 for the C-shaped beam. In addition, since the intermediate ceiling suspension bracket 23 provided in the intermediate structure portion that supports the ceiling and the floor includes the vibration isolating rubber member 54, vibration applied to the floor is reduced by the vibration isolating rubber member 54. Transmission to the ceiling is suppressed.

  In the uppermost ceiling hanging bracket 64, the first horizontal portion 66, the first vertical portion 69, the second horizontal portion 67, the second vertical portion 70, and the third horizontal portion 68 are connected in order, and the first horizontal portion 66 is connected to the first horizontal portion 66. Since the 3rd horizontal part 68 is piled up, the rigidity of the top ceiling suspension metal fitting 64 comprised in plate shape is strengthened. Since the height of the uppermost ceiling hanger 64 is reduced without losing the rigidity required to support the ceiling base material 20, an increase in the height of the uppermost structural portion 15 is suppressed.

  Moreover, since the recessed part 51 and the convex part 50 are formed in the surface of the vertical part 44 of the intermediate | middle ceiling suspension metal fitting 23, the rigidity of the intermediate | middle ceiling suspension metal fitting 23 is strengthened. Therefore, complication of the structure of the intermediate ceiling hanger 23 is suppressed without losing the rigidity required to support the ceiling base material 20.

  Further, in the intermediate ceiling hanger 23, the horizontal groove 48 is formed so as to exceed the vertical groove 49 by a predetermined distance 101 in the first horizontal direction 8, so that the end face of the flange 26 of the H-shaped beam 21 becomes the horizontal groove 48. The abutting position is different from the position where the surface of the lip 63 of the C-shaped beam 22 hits the vertical groove 49. Therefore, when the same field receiver 24 is supported by the H-shaped beam 21 and the C-shaped beam 22 arranged in series via the intermediate ceiling hanging bracket 23, the end face of the lip 63 of the C-shaped beam 22 is H-shaped. Even if it is away from the end face of the flange 26 of the beam 21, by setting the predetermined distance 101 according to the separation distance 102, the edge receiver 24 can be comfortably formed by the intermediate ceiling hanging bracket 23 of the same type. It is supported by both C-shaped beams 22.

  Further, in the intermediate ceiling hanger 23, the predetermined distance 101 where the horizontal groove 48 exceeds the vertical groove 49 is the same as or separated from the separation distance 102 between the end faces of the C-shaped beam 22 and the H-shaped beam 21 arranged in series. Less than distance 102. Here, the mounting position of the intermediate ceiling hanging bracket 23 on the C-shaped beam 22 is limited to the width in the first horizontal direction 8 of the vertical groove 49, and the mounting position of the intermediate ceiling hanging bracket 23 on the H-shaped beam 21 is horizontal. It is limited to the width of the groove 48 in the first horizontal direction 8. The mounting position of the intermediate ceiling hanger 23 with respect to the H-shaped beam 21 can be freely changed in one direction 8A in the first horizontal direction 8 as long as it does not deviate from the beam screw hole 45, and in the other direction 8B in the first horizontal direction 8. Can be freely changed within the range of the predetermined distance 101. Since the separation distance 102 is the same as or smaller than the predetermined distance 101, the intermediate ceiling hanging bracket fixed to the C-shaped beam 22 is changed by changing the mounting position of the intermediate ceiling hanging bracket 23 with respect to the H-shaped beam 21. The position of 23 and the position of the intermediate ceiling hanging bracket 23 fixed to the H-shaped beam 21 are aligned in the first horizontal direction 8. When the position of the intermediate ceiling hanging bracket 23 fixed to the C-shaped beam 22 and the position of the intermediate ceiling hanging bracket 23 fixed to the H-shaped beam 21 are aligned in the first horizontal direction 8, the same field edge receiver 24 becomes C The intermediate ceiling hanging bracket 23 fixed to the beam 22 and the intermediate ceiling hanging bracket 23 fixed to the H beam 21 are attached without distortion. Therefore, the field receiver 24 can be supported by both the H-shaped beam 21 and the C-shaped beam 22 without difficulty by the same type of intermediate ceiling hanging bracket 23.

  In the uppermost ceiling hanging bracket 64, the beam screw hole 72 is formed in the second horizontal portion 67, whereas the field edge receiving holes 71 and 73 are formed in the first horizontal portion 66 and the third horizontal portion 68, respectively. ing. The horizontal groove 75 is formed in the first vertical portion 69 and the second vertical portion 70. The flange 26 of the H-shaped beam 21 or the flange 58 of the C-shaped beam 22 is attached to the horizontal groove 75, and the upper surfaces of the flanges 26 and 58 are in contact with the upper surface 75 b of the horizontal groove 75. The first horizontal portion 66 and the third field edge receiving holes 71 and 73 are located higher than the upper surface 75 b of the horizontal groove 75. Further, at the height position where the horizontal groove 75 is located and the height position below the horizontal groove 75, the first vertical portion 69 and the second vertical portion 70 where the horizontal groove 75 is formed are connected to the edge receiving hole 71, The first horizontal direction 8 is more spaced apart from the first horizontal direction 8 than 73. Therefore, as shown in FIG. 8, even if the field edge receiver 24 and the field edge reception nut 42 are disposed at positions close to the field edge reception holes 71 and 73, the field edge reception 24 and the field edge reception nut 42 are Interference with the top ceiling hanger 64 is prevented. Therefore, the distance in the vertical direction 7 between the flange 26 fixed to the uppermost ceiling hanging bracket 64 and the field edge receiver 24 can be reduced as compared with the case of the intermediate ceiling hanging bracket 23. As a result, the width in the up-down direction 7 of the uppermost structure portion 15 can be shorter than the width of the first intermediate structure portion 13 in the up-down direction 7.
