The arrangement of the grooves 40 will be described later.

  The positioning structure 100 includes a detent member 50. The anti-rotation member 50 is formed in a gap (gap between the steel frame 201 and the positioning member 30) formed by the groove 20 and the groove 40 facing each other in accordance with the rotational position in the hole 10 of the positioning member 30. This is a member that is inserted and prevents the positioning member 30 from rotating in the hole portion 10, and is a rod-shaped metal member in this embodiment. In the present embodiment, the cross-sectional shape of the groove portions 20 and 40 is substantially semicircular, and the cross-sectional shape of the anti-rotation member 50 is circular according to this, but the cross-sectional shape of the anti-rotation member 50 is the cross-section of the groove portions 20 and 40. It can be arbitrarily set according to the shape. Further, in the present embodiment, two anti-rotation members 50 are provided, but one may be used.

  The positioning member 30 has an attachment portion 60 for attaching the sash 300 to the positioning member 30 via a bracket 80. In the case of this embodiment, the attachment portion 60 is formed as a screw hole drilled in the axial direction on the side surface 31 of the positioning member 30 at a position eccentric from the axial center L1 of the positioning member 30. A line L2 indicates the axis of the mounting portion 60. In the case of the present embodiment, the attachment portion 60 penetrates the positioning member 30, but may be a bottomed screw hole.

  The positioning structure 100 includes a fixing member 70. The fixing member 70 includes a shaft portion 71 and a head portion 72. The shaft portion 71 has a screw portion that is screwed into the attachment portion 60. The head 72 has a cylindrical shape. In the present embodiment, the mounting portion 60 is a screw hole, and the screw portion is configured on the shaft portion 71 of the fixing member 70. However, the mounting portion 60 is a screw rod-shaped shaft body and the fixing member 70 is formed with a screw hole. Also good.

  The bracket 80 has a size that substantially covers the inner surface of the vertical frame portion of the sash 300 (the portion closer to the steel frame stand 201 than the glass 400), and is formed in a flat plate shape. A long hole 81 is formed in the bracket 80 at a position corresponding to each hole 10 of the steel frame stand 201. The shaft portion 71 of the fixing member 70 is inserted into the long hole 81, and the width of the long hole 81 in the short direction is substantially the same as the diameter of the shaft portion 71. Further, the bracket 80 has an engaging portion 82 for engaging with the vertical frame portion of the sash 300 and connecting to the sash 300.

  The spacer 91 is a flat plate member interposed between the positioning member 30 and the bracket 80, and a long hole 91 a through which the shaft portion 71 of the fixing member 70 is inserted is formed. The washer 92 has a hole 92 a into which the shaft portion 71 of the fixing member 70 is inserted, and is disposed between the bracket 80 and the head 72 of the fixing member 70.

  In the positioning structure 100 having such a configuration, first, the positioning member 30 is inserted into the hole 10 when assembling. The position of the sash 300 in the direction of entering and exiting is adjusted according to the rotational position of the positioning member 30 in the hole 10, which will be described later.

  Subsequently, the rotation preventing member 50 is inserted into the gap formed by the groove 20 and the groove 40 to prevent the positioning member 30 from rotating. Next, the engaging portion 82 of the bracket 80 is engaged with the sash 300, and the shaft portion 71 of the fixing member 70 is inserted through the washer 92, the bracket 80, and the spacer 91 in this order, and is screwed into the mounting portion 60 of the positioning member 30. To conclude. As described above, the assembly of the positioning structure 100 is completed, and the sash 300 is supported by the building housing 200.

  Thus, in this embodiment, since the sash 300 is attached to the positioning member 30 by fastening the positioning member 30 and the fixing member 70 with screws, it is not necessary to provide welding work and equipment for welding and improve workability. it can. Further, the positioning structure 100 can be made compact.

  FIG. 3 is a horizontal sectional view of the periphery of the positioning structure 100 in a state where the sash 300 is assembled to the building housing 200. In the drawing, two sashes 300 adjacent to one steel frame stand 201 are supported, and the positioning structure 100 of each sash 300 shares the positioning member 30 and the hole 10. As shown in the figure, the distance X between the axial center L1 of the positioning member 30 and the axial center L2 of the mounting portion 60 in plan view is the adjustment amount of the sash 300 in the entry / exit direction.

  The engaging portion 82 of the bracket 80 is engaged with the engaging portion 301 provided in the vertical frame portion of the sash 300, and the spacer member 302 is inserted between the engaging portion 82 and a part of the vertical frame portion of the sash 300. Thus, the bracket 80 is prevented from moving in the direction of entering and exiting the sash 300. The engaging portion 82 and the engaging portion 301 are slidable relative to each other in a direction orthogonal to the entering / exiting direction. When the steel frame 201 is deformed by an external force such as an earthquake, the entering / exiting portion is provided. The deformation in the direction orthogonal to the direction is difficult to be transmitted to the sash 300.

  Further, minute projections are provided on the side surface of the engaging portion 82 and the side surface of the spacer member 302, respectively, so that they are in line contact instead of surface contact. This is to prevent the bracket 80 and the spacer member 302 from “galling”.

  Since the bracket 80 substantially covers the inner surface of the vertical frame portion of the sash 300 (the portion closer to the steel frame 201 than the glass 400), the design of the peripheral edge of the glass 400 is improved. Moreover, since the positioning structure 100 is covered with the bracket 80 except for the head 72 of the fixing member 70, the design of the peripheral edge of the sash 300 mounting portion can be improved.

  Next, a method for adjusting the position of the sash 300 in the entry / exit direction by the positioning structure 100 will be described.

  4A to 4F are views of the state in which the positioning member 30 is inserted into the hole 10 while changing the rotational position, as viewed from the side surface 31 of the positioning member 30. FIG. In the case of the present embodiment, it is assumed that the mounting portion 60 is eccentric by 3 mm from the axis of the positioning member 30. Further, twelve groove portions 40 are formed, and are formed at unequal pitches in the circumferential direction of the positioning member 30.

  The side surface 31 of the positioning member 30 is provided with marks 32 a and 32 b that indicate the rotational position of the positioning member 30 in the hole 10. In the case of the present embodiment, the mark 32 a and the mark 32 b are different marks (the former is one point and the latter is two points), and they are separated by an angle of 90 degrees when viewed from the axis of the positioning member 30. . By providing such marks 32a and 32b, when the positioning member 30 is inserted into the hole 10, the rotational position of the positioning member 30 can be grasped, so that workability can be improved.

  FIG. 4A shows a case where the axis of the mounting portion 60 and the axis of the positioning member 30 are located on the same vertical line. In this case, the adjustment amount X of the sash 300 in the entry / exit direction is 0 mm. Thus, by changing the rotational position of the positioning member 30 in the hole 10, in other words, by changing the combination of the groove 20 and the groove 40 into which the anti-rotation member 50 is inserted, the adjustment amount X can be changed. Can be changed. When the mounting portion 60 is decentered by 3 mm from the axis of the positioning member 30 as in the present embodiment, the maximum value of the adjustment amount X is 3 mm in one direction and the opposite direction of the exit / entry direction, and the total range is 6 mm. The adjustment amount X can be set within the range.

  FIG. 4B shows a state in which the adjustment amount X of the sash 300 in and out of the sash 300 is set to +1.05 mm, FIG. 4C shows a state in which the adjustment amount X is set to +1.25 mm, and FIG. FIG. 4E shows the set state, FIG. 4E shows the state set to +2.61 mm, and FIG. 4F shows the state set to +3.00 mm. 4B to 4F show an example in which the adjustment amount X is changed in one direction of the exit / entry direction. By reversing the positioning member 30 and inserting it into the hole 10, the direction opposite to the exit / entry direction is shown. Also, the adjustment amount X can be changed similarly.

  The number of options for the adjustment amount X depends on the positions where the groove 20 and the groove 40 are formed. As the number of the groove portions 20 and the groove portions 40 increases, the number of options of the adjustment amount X increases. However, even if the combination of the groove portion 20 and the groove portion 40 into which the rotation preventing member 50 is inserted differs, the adjustment amount There may be cases where X becomes the same.

  For example, when paying attention to the groove portion 40, if the groove portion 40 is located at a symmetrical position with respect to a line passing through the axis of the positioning member 30 and the attachment portion 60, the choice of the adjustment amount X is half the number of the groove portions 40. It will not be proportional to. If a plurality of groove portions 40 are formed at unequal pitches in the circumferential direction of the positioning member 30 as in the present embodiment, the groove portions 40 are positioned symmetrically with respect to a line passing through the axis of the positioning member 30 and the mounting portion 60. Positioning can be avoided, and options for the adjustment amount X of the sash 300 in and out of the sash 300 can be effectively increased.

  Thus, in this embodiment, since the attachment part 60 is provided in the positioning member 30 in the position eccentric from the axial center of the positioning member 30, the entrance / exit direction of the sash 300 by the rotation position of the positioning member 30 in the hole 10 is demonstrated. The position of is determined. Therefore, the position of each hole 10 is measured in advance, and the adjustment amount X in the direction in and out of the sash 300 is calculated for each positioning structure 100, and each positioning in each hole 10 is adjusted according to the adjustment amount X. By determining the rotational position of the member 30, the positioning adjustment of the sash 300 in the direction of entering and exiting can be easily performed.

  In addition, as a measuring method of the position of the hole part 10, the measurement using a transit is mentioned, for example. Further, the height of the shaft center of the shaft portion 71 of the fixing member 70 differs depending on the rotation position of the positioning member 30. However, the hole of the bracket 80 through which the shaft portion 71 passes is a long hole 81, so that the fixing is performed. The relative position of the member 70 and the bracket 80 in the vertical direction can be changed, and the change in the height of the shaft center of the shaft portion 71 of the fixing member 70 can be handled.

It is a disassembled perspective view of the building frame 200 and the sash 300 which is a wall member to which the positioning structure (100) of the wall member which concerns on one Embodiment of this invention is applied. It is a perspective view of positioning structure 100 concerning one embodiment of the present invention. It is a horizontal sectional view of the periphery of the positioning structure 100 in a state where the sash 300 is assembled to the building housing 200.
