An embodiment of a sash mounting structure embodying the present invention will be described below with reference to the drawings.
As shown in FIG.2 and FIG.3, the beam 21 is each arrange | positioned at each hierarchy of a building. As shown in FIG. 6, a floor slab 26 of each level is installed at the upper part of the beam 21, and a ceiling panel 27 is installed at the lower part.

  As shown in FIGS. 1 and 2, the outer wall of the building of this embodiment is configured by arranging a large number of wall panels 22. Each wall panel 22 has a window opening between the upper and lower ends of the wall panel 22 and the other wall panels 22 arranged in the vertical direction so as to alternately overlap the upper and lower ends of the other wall panel 22 adjacent in the horizontal direction. Are arranged at intervals S so as to be formed. As shown in FIGS. 4 and 5, the wall panel 22 is made of a concrete material in the shape of a vertically long rectangular plate, and the front surface thereof is curved and formed in an arc shape so that the central portion in the vertical direction is convex. . Tiles 22c are embedded in the surface of the wall panel 22 except the back surface. As shown in FIGS. 3 and 11, the wall panel 22 is rigidly joined to the beam 21 through brackets 22b at support points 22a at both upper and lower ends of the back surface. Here, the lower bracket 22 b of the wall panel 22 is fixed to the upper surface of the beam 21, and the upper bracket 22 b is fixed to the lower surface of the beam 21.

  As shown in FIGS. 2 and 3, a window sash 23 is disposed in each of the intervals S. As shown in FIGS. 3 and 12, the lower side of each sash 23 is rigidly joined to the upper surface of the lower beam 21 via the lower bracket 28. The upper side of each sash 23 is rigidly joined to the lower surface of the upper beam 21 via the upper bracket 29. Glasses 24 and 25 are fitted in each sash 23.

  Therefore, as shown in FIG. 3, the brackets 28 and 29 of the sash 23 and the brackets 22b of the wall panel 22 adjacent to both sides thereof are set to a height corresponding to the horizontal direction.

Next, a detailed description will be given of a mounting structure including the lower bracket 28 and the upper bracket 29 of the sash 23 with respect to the beam 21 of each level of the building.
First, the lower bracket 28 will be described. As shown in FIGS. 3, 6, and 7, a pair of left and right first lower bracket pieces 30 are disposed on the upper surface of the lower beam 21 in each level of the building. Rigidly joined by welding in a protruding state. As shown in FIG. 7, a second lower bracket piece 31 made of a plate material is rigidly joined to the upper end of each first lower bracket piece 30. The rigid joining of the second lower bracket piece 31 is achieved by bolts 32 and nuts 33 and welding. A lower support plate 34 is attached to each second lower bracket piece 31. The lower support plate 34 is formed with a long hole 34a extending in the vertical direction for absorbing an assembly error, and the lower hole 34a and a bolt 35 and a nut (not shown) inserted through the hole of the second lower bracket piece 31 The support plate 34 can absorb the assembly error by adjusting the position in the vertical direction. The lower end of the sash 23 is fixed to the lower support plate 34 by bolts 39 and nuts 40. And the said volt | bolts 35 and 39 are arrange | positioned so that the axis line may become a perpendicular direction. Accordingly, the lower portion of the sash 23 and the lower support plate 34 are rigidly joined to the second lower bracket piece 31, and as a result, the lower portion of the sash 23 is rigidly joined to the beam 21.

Next, the upper bracket 29 will be described. As shown in FIGS. 3, 6, and 8, a pair of left and right first upper bracket pieces 41 are provided on the lower surface of the upper beam 21 at each level of the building. Rigidly joined by welding in a protruding state. As shown in FIG. 8, the second upper bracket piece 42 is rigidly joined to the lower end of each first upper bracket piece 41. The rigid connection of the second upper bracket piece 42 is achieved by bolts 43 and nuts 44 and welding. An upper support plate 45 is attached to each second upper bracket piece 42. The upper support plate 45 is formed with a long hole 45a extending in the vertical direction for absorbing assembly errors, and the upper support plate is formed by the long hole 45a and a bolt 46 and a nut (not shown) inserted through the second upper bracket piece 42. The vertical position of 45 can be adjusted to absorb assembly errors. The upper end of the sash 23 is fixed to the upper support plate 45 by bolts 50 and nuts 51. And the said volt | bolts 46 and 50 are arrange | positioned so that the axis line may become a perpendicular direction. Accordingly, the upper portion of the sash 23 and the upper support plate 45 are rigidly joined to the second upper bracket piece 42, and as a result, the upper portion of the sash 23 is rigidly joined to the beam 21.

Each sash 23 is disposed at a position inside the wall panel 22, and a seal 52 is interposed between the sash 23 and the wall panel 22 by filling.
Next, the operation of the sash mounting structure configured as described above will be described.

  Now, in the building having the sash mounting structure of this embodiment, when an earthquake occurs, interlayer displacement occurs between the upper and lower beams 21 in each layer, as shown in FIG. In this case, a window sash 23 is attached between a lower bracket 28 and an upper bracket 29 rigidly joined to the upper and lower beams 21.

  As shown in FIG. 11, since the height of the support point 23a of the sash 23 and the support point 22a of the wall panel 22 hardly change, the sash 23 and the wall panel 22 can move almost in the horizontal direction. . Therefore, the relative displacement between the sash 23 and the wall panel 22 due to the interlayer displacement between the upper and lower beams 21 can be minimized, and the risk of the seal 52 being broken can be suppressed.

  On the other hand, as shown in FIGS. 10 and 12, in the conventional sash mounting structure described in Patent Document 1, the support point 122a of the wall panel 122 and the support point 123a of the sash 123 are embodiments. Since it is separated in the vertical direction as compared with the structure of, the support point 123a of the sash 123 is coupled with the pin joint, so that the relative displacement between the wall panel 122 and the sash 123 is increased, and the seal breakage is likely to occur. . FIGS. 11 and 12 are schematic diagrams exaggerating the operation, in which the deformation of each part is ignored and dimensional errors are allowed.

Therefore, according to this embodiment, the following effects can be obtained.
(1) In the sash mounting structure of this embodiment, the lower bracket 28 protruding upward is rigidly joined to the lower beam 21 of the building hierarchy, and the upper bracket 29 protruding downward to the upper beam 21 is provided. It is rigidly joined. A sash 23 is attached between the lower bracket 28 and the upper bracket 29. For this reason, even if the vertical dimension of the sash 23 is short and an interlayer displacement occurs between the upper and lower beams 21 when an earthquake occurs, the relative displacement between the sash 23 and the wall panel 22 can be reduced. Can be reduced more reliably.

  (2) In the sash mounting structure of this embodiment, the relative displacement between the sash 23 and the wall panel 22 can be reduced, so that an excessive external force is unlikely to act on the sash 23. For this reason, damage to the sash 23 and the glass in the sash 23 can be suppressed.

(3) In this sash mounting structure, since the brackets 48 and 49 of the sash 23 are merely rigidly joined to the beam 21, the number of parts does not increase and the configuration is simple.
(Example of change)
In addition, this embodiment can also be changed and embodied as follows.

-The present invention is applied not only to a multi-level building but also to a single-level building.
The first and second lower bracket pieces 30, 31 and the first and second upper bracket pieces 41, 42 are respectively integrated.
