Embodiments of the present invention will be described below based on the accompanying drawings.
As shown in FIG. 1, the external wall panel 5 for the protruding corner of this embodiment has an approximately L-shaped external wall panel 51 having two intersecting surfaces (two orthogonal surfaces when intersecting at right angles). It has a structure in which a plurality of sheets are lined up and interconnected with a base material 52. The outer wall panel 5 includes, for example, a plurality of vertical edges 52a as the base material 52. These vertical furrings 52a are made of square steel pipes, but a steel material having an open cross-sectional shape may also be used.

The outer wall surface material 51 is, for example, a metal sandwich panel in which a noncombustible heat insulating material 51a is sandwiched between steel plates 51b and 51c, as shown in FIGS. 2(A) and 2(B). When the two exterior wall panels 51 are arranged vertically, this metal sandwich panel is placed in two widthwise long recesses 51d formed on the upper end surface of the outer wall panel 51 located in the lower section, and the upper section is located in the upper section. By fitting the two widthwise long convex portions 51e formed on the lower end surface of the outer wall surface material 51, the upper and lower outer wall surface materials 51 are engaged with each other so as not to be misaligned in the out-of-plane direction.

Further, as shown in FIG. 4, the fastener 6 is provided at a location that does not face (does not hide) the corner post 101 of the protruding corner of each outer wall portion 53.

Incidentally, a flat plate-shaped outer wall panel (not shown) is arranged next to the outer wall panel 5 for the protruding corner and is joined to each other. The joining position (vertical joint position) between this flat plate-shaped external wall panel and the above-mentioned external wall panel 5 is a position away from the corner post 101 without facing the corner post 101 so that joint treatment can be performed from the floor slab side. I am trying to make it so that If the vertical joint processing position is located away from the corner post 101 in this way, the space between the corner post 101 and the outer wall panel 5 becomes difficult to see from the left and right ends of each outer wall portion 53, and the outer wall It becomes difficult to visually confirm the alignment (particularly in the vertical direction) of the projecting corner angle (vertical corner portion) of the panel 5. Furthermore, it is not possible to directly touch the projecting corners of the outer wall panel 5.

This L-shaped main body portion 61 is made non-rotatable by having its vertical piece portion secured to the vertical rim 52a with two bolts 62 in advance. In this embodiment, a plate member having a thickness equivalent to that of the vertical plate part of the L-angle 7 is provided between the vertical piece part of the L-shaped main body part 61 and the vertical rim 52a. 67 so that the vertical plate portion of the L angle 7 fits between the vertical piece portion and the vertical furrow 52a, but the present invention is not limited thereto. Furthermore, for example, triangular reinforcing plates may be provided that are welded and fixed to the vertical and horizontal pieces of the L-shaped main body 61.

A screw hole is formed vertically in the horizontal piece of the L-shaped main body portion 61 (nut welding may be used), and a headed adjustment bolt 63 is screwed into this screw hole. The lower hemispherical portion of the adjustment bolt 63 contacts the upper surface of the pedestal 71. When the adjustment bolt 63 is tightened, the L-shaped main body 61 moves upward, and the outer wall panel 5 can be moved upward. When the adjustment bolt 63 is loosened, the outer wall panel 5 will be lowered by its own weight.

Further, an insertion hole 64 is formed in the horizontal piece portion of the L-shaped main body portion 61 in the vertical direction, and when the outer wall panel 5 is lifted up and lowered by a crane, the insertion hole 64 is inserted into the insertion hole 64. A threaded bolt 72 can be inserted therethrough. Further, the fastener 6 includes a nut 65 that is screwed onto the threaded bolt 72, and a washer 66 that is interposed between the nut 65 and the insertion hole 64. The force caused by tightening the nut 65 is applied to the L-shaped main body portion 61 via the washer 66. That is, by tightening the nut 65, a force is applied in a direction to push down the outer wall panel 5. On the other hand, when the nut 65 is loosened, the outer wall panel 5 comes to rest at a position where the adjustment bolt 63 contacts the upper surface of the pedestal 71. In this embodiment, the fastener 6 fixes the outer wall panel 5 to the building 100 by generating a pushing force against the outer wall panel 5 by the adjusting bolt 63 and a pushing force against the outer wall panel 5 by the nut 65. It has a fixing function to adjust the height position of the outer wall panel 5 and an adjustment function to adjust the height position of the outer wall panel 5. Further, in this embodiment, the fastener 6 is attached to the vertical rim 52a even if the adjustment bolt 63 is displaced in the horizontal direction with respect to the core of the base material 52, as shown in FIGS. 5 and 6. Since the fastener 6 is fixed in a non-rotatable manner, the above-mentioned pushing up force can be transmitted to the outer wall panel 5.

As shown in FIG. 3, for the upper exterior wall panel 5 to be installed at the projecting corner of the building 100, the above-mentioned fasteners are attached to the floor slab 103 on the floor above the floor on which the lower exterior wall panel 5 has already been attached.

A worker who fixes the outer wall panel 5 on the floor slab 103 operates the fastener 6 and lowers or raises the outer wall panel 5, thereby moving the top of the upper outer wall panel 5 to the marked position. , and the lower end of the upper outer wall panel 5 is engaged with the top end of the lower outer wall panel 5. At this time, the other workers on the floor slab 103 visually check the marking position by the laser beam and the top position of the upper outer wall panel 5, and tell the worker who is performing the above-mentioned fixing work to the outer wall panel 5. It is also possible to issue instructions for descent or ascent.

Here, each outer wall portion 53 of the outer wall panel 5 is provided with a fastener 6 having a fixing function for fixing the outer wall panel 5 to the building 100 and an adjustment function for adjusting the height position of the outer wall panel 5. Since two fasteners are provided in the horizontal direction, using these two fasteners 6, it is possible to level the top of each outer wall portion 53 and adjust the height position of each outer wall portion 53 accurately. . In other words, using two fasteners 6, one of them is used as a fulcrum, the other is used as a point of force, and the projecting corner angle (projecting corner apex) of the external wall panel 5 is used as the point of action. It is possible to adjust the position (particularly in the vertical direction) of the corner apex. For example, among the two fasteners 6 in each outer wall portion 53, first operate the fastener 6 on the side far from the corner post 101 to adjust the height position of the outer wall panel 5 on the side far from the corner post 101. Then, by operating the fastener 6 on the side closer to the corner post 101, the height position of the outer wall panel 5 on the side closer to the corner post 101 is adjusted, and the top of the outer wall panel 5 is positioned horizontally. be able to. In addition, contrary to the above-described operation, adjustment can also be made by first operating the fastener 6 on the closer side and then operating the fastener 6 on the side farther from the corner post 101. In a configuration in which each outer wall portion 53 is provided with only one fastener, it is not possible to perform position adjustment by such lever action.

Furthermore, in this embodiment, the two or more fasteners 6 are provided at locations that do not face the corner posts 101 of the protruding corners of each outer wall portion 53. That is, the two fasteners 6 are operated at easy-to-operate locations that are not hidden by the corner posts 101, and the top end of the outer wall panel 5 is leveled by visual inspection, which is not hidden by the corner posts 101. This can be done by checking as much as possible. Here, since the above-mentioned external wall panel 5 used for the projecting corner is not a combination of two separate left and right flat panels, but an L-shaped external wall panel 51 having two integral sides, the above-mentioned Even by adjusting the position within the visible range as shown in FIG. Note that the horizontal adjustment of the outer wall panel 5 can be corrected by, for example, attaching a suction cup grip to the panel surface and having the worker grasp and move the suction cup grip.

An exterior wall panel of another embodiment will be described based on FIG. 7.
