2. Description of the Related Art In recent years, precast wallboards are often used for outer walls of buildings such as buildings. Since the precast wall plate is provided between floors, it has a large width of, for example, 6000 mm and a height of 2,400 mm. Then, a metal finishing material is attached to the surface of the precast wall plate serving as the outer wall as a decorative finish of the building exterior.

When the finishing material is attached to a precast wall plate, the coefficient of thermal expansion is, for example, that of a concrete precast wall plate (α = 6.8 to 12.7) and a metal finishing material (for example, α with iron). = 12) is about twice as large, so the finished material thermally expands or shrinks more than the precast wallboard due to the heat of summer or the cold of winter. When the finishing material is attached, the finishing material deforms. Therefore, to prevent the finish from being deformed by the effects of thermal expansion and thermal shrinkage, the finish should be 1/1 of the precast wallboard.
Use a small size of about 3 to 1/10, use the peripheral edge of the finishing material, etc. to attach bolts to the precast wall plate at the construction site,
It was mounted and fixed using fastening means such as mounting hardware.

Next, a procedure for attaching the finishing material to the precast wallboard in this embodiment will be described. First,
The finishing material 2 and the lattice frame 3 are integrally joined. In the joining, the finishing material 2 and the lattice frame 3 are overlapped, and thereafter, the entire surface of the finishing material 2 is integrally joined by welding at a plurality of locations at predetermined intervals. Since the finishing material 2 is integrally joined to the lattice frame 3 as described above, the flexible finishing material 2 is reinforced so as not to bend easily.

Next, the finishing material 2 integrated with the lattice frame 3 is attached to the precast wall plate 1. First, the installation
A locking bolt pin 9 is inserted into the mounting hole 6d of each third mounting bracket 6 of the precast wall plate 1 laid on the site, and a locking nut 10 is screwed into the locking bolt pin 9 to lock the locking bolt pin 9 into the second position. 3 Attach to the mounting bracket 6. The locking bolt pin 9 may be attached to the third attachment 6 by welding. Next, the finishing material 2 integrated with the grid frame 3 is superimposed on the precast wall plate 1 and each second frame of the grid frame 3 is placed on the horizontal stopper plate 6c of each third mounting bracket 6 as shown in FIG. The upright mounting plate 8a of the mounting bracket 8 is placed, and the locking bolt pin 9 is inserted into the mounting locking hole 8b of the upright mounting plate 8a. If a neoprene rubber (not shown) or the like is interposed between the upright mounting plate 8a and the locking nut 10 at this time, a buffering effect against wind vibration is expected, and vibration noise is reduced.

Thereafter, the lattice frame 3 integrated with the finishing material 2
Is moved in the height direction to align the mounting holes 4c of the first mounting brackets 4 on the upper side of the precast wall plate 1 with the mounting locking holes 7a of the first mounting receivers 7 on the right side of the lattice frame 3. At this time, since each of the second mounting members 5 on the lower side of the precast wall plate 1 has a mounting slot 5c extending in the height direction, each of the mounting slots 5c and the first The mounting locking holes 7a of the mounting receiver 7 are also aligned. When the positioning of the grid frame 3 integrated with the finishing material 2 with respect to the precast wall plate 1 is thus completed, the mounting holes 4c and the mounting locking holes 7a aligned with each other as shown in FIGS. Slot 5c
The mounting bolts 11 are inserted into the mounting locking holes 7a, and the mounting nuts 12 are screwed into the mounting bolts 11 so that the finishing material 2 is provided on both the upper and lower sides of the precast wall plate 1.
The upper and lower sides of the lattice frame 3 integrated with the above are attached. Therefore, the finishing material 2 having the same size as the precast wall plate 1 can be easily attached by screwing the small number of the mounting bolts 11 and the mounting nuts 12.

In this way, the precast wallboard 1 to which the finishing material 2 integrated with the lattice frame 3 is attached is attached to the building frame to form an outer wall of the building. Then, after the construction, for example, the precast wallboard 1 and the finishing material 2 thermally expand due to summer heat, but when the finishing material 2 thermally expands to the precast wallboard 1 or more due to a difference in linear expansion coefficient between the two, the finishing material 2 Since the upper side in the height direction is fixed to the precast wall plate 1 by the first mounting bracket 4, the first mounting bracket 7, the mounting bolt 11, and the mounting nut 12, the upper side of the finishing material 2 is used as a base point. The lower side will extend.

The elongated mounting hole 5c of each of the second mounting brackets 5 attached to the lower side of the precast wall plate 1 extends in the height direction. Since the mounting bolts 12 inserted into the mounting locking holes 7a of the fixture 7 can move in the height direction in the mounting long holes 5d of the second mounting bracket integrated with the precast wall plate 1, the mounting bolts 12 are located below the finishing material 2. The side can move in the height direction with respect to the precast wallboard 1. A locking bolt pin 9 inserted into a mounting hole 6d penetrated in the height direction of each third mounting bracket 6 mounted on substantially the entire surface of the precast wall plate 1 and fastened by a locking nut 10, Since only the mounting locking holes 8b of the upright mounting plates 8a of the respective second mounting receivers 8 attached to substantially the entire surface of the finishing material 2 are inserted, the second mounting receiver 8 integrated with the finishing material 2 is provided. Can be moved in the axial direction of the locking bolt pin 9, that is, in the height direction of the precast wall plate 1. Can move.

Accordingly, the precast wallboard 1 to which the finishing material 2 is attached is mounted on the building vehicle, and the finishing material 2
Is larger in size than the precast wallboard 1, the finishing material thermally expands or shrinks more than the precast wallboard due to the heat of summer or the cold of winter. Even if it extends or shrinks, for example, the part other than the upper side of the finishing material 2
Can be moved in the height direction, and the elongation or contraction of the finishing material 2 in the height direction is absorbed by the movement, so that the finishing material 2 is not deformed in the height direction by the temperature load. Further, even if a peeling force in the thickness direction with respect to the precast wallboard acts on the finishing material 2 due to the wind load, the finishing material 2 is fixed on its upper side, and all other joints also have the thickness of the precast wallboard 1. Since it is fixed so as not to move in the direction, it can sufficiently resist.

3 is extended through the height direction and extends in the width direction, so that all parts other than the center position on the upper side of the finishing material 2 with respect to the precast wall plate 1 are the precast wall plate. 1 can move in the width direction, and all the parts other than the upper side of the finishing material 2 can move not only in the height direction of the precast wall plate 1 but also in the width direction. Since the elongation and shrinkage in the width direction due to the heat are absorbed by the movement, the finishing material 2 is not deformed in the height direction as well as in the width direction by the temperature load. In any of the above embodiments, the finishing material 2 is made of stainless steel. However, it is a matter of course that the finishing material 2 may be made of metal such as aluminum, iron, and titanium.
