[0002]

2. Description of the Related Art In a conventional concrete outer wall panel, a concrete surface plate such as an ALC veneer is joined to the surface of a framework using appropriate screws.

[0003]

However, when the surface plate is attached to the framework only by screwing, the quantitative safety standard which does not function due to the deterioration of the screw is unclear.
Therefore, for example, in the event of an earthquake or the like, if the screw is not sufficiently effective, it has not been determined whether the surface plate will fall off or fall.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a concrete outer wall panel which can reliably prevent the concrete outer wall panel from falling off and falling even when the screw becomes ineffective in an earthquake or the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete outer wall panel according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a partially cutaway perspective view of a concrete outer wall panel according to this embodiment. In this outer wall panel, as shown in FIG. 1, a concrete surface plate 2 is joined to a surface of a framework 1. The surface plate 2 is made of an ALC single plate or the like.
As shown in FIG.
Fixed at. The framework 1 includes an outer peripheral frame 3 and a plurality of middle crossbars 4 arranged therein. The outer frame 3 includes an upper frame 3a,
It is framed by a lower frame 3b and a pair of vertical frames 3c, 3c.
Each member of the outer peripheral frame 3 and the middle rail 4 are formed of channel steel. One of the joints is drawn and fitted so that the outer surface of the channel steel flange to which the surface plate 2 is attached is flush with each other, and is fixed by welding or the like. In FIG. 1, the surface plate 2
Is 80 mm, and the width of the channel steel is 100 mm.

As shown in FIGS. 1, 2 and 5, a plurality of plates 5 are fixed to a pair of vertical frames 3c of the outer peripheral frame 3 by welding or the like. The plate 5 has a substantially Z-shape bent at the center, and the other piece 5b is vertically aligned so that one piece 5a protrudes into the outer peripheral frame 3 and the outer surface of the flange 5c is flush with the outer surface of the vertical frame 3c. 3c is fixed to the inner surface of the flange. A bolt insertion hole 6 is formed in one of the pieces 5a, and the surface plate 2 corresponding to the bolt insertion hole 6 is formed.
A buried nut 7 is buried at the position. Then, the surface plate 2 is connected to the vertical frame 3 c via the plate 5 by the bolt 8 which is inserted through the bolt insertion hole 6 and screwed into the embedded nut 7.
Fixed to

Further, as shown in FIG.
A support plate 9 is attached to the lower surface of b. in this case,
The support plate 9 is fixed to the web of the lower frame 3 b by welding or the like so as to protrude toward the surface side of the framework 1, and supports the lower surface of the surface plate 2. Further, as shown in FIG. 1, a heat insulating material 10 is provided inside the framework 1, and an interior base material 11 is attached to a back surface of the framework 1.

Next, the assembly of the concrete outer wall panel will be described. After the framework 1 is previously framed as described above, the screws 12 are screwed from the front side of the surface plate 2 and fixed to the middle crossbar 4 with the lowermost surface plate 2 placed on the support plate 9. Further, the bolt 8 is passed through the bolt insertion hole 6 of the plate 5 from the back side of the surface plate 2 and screwed into the embedded nut 7. As a result, the lowermost surface plate 2 is fixed to the surface of the framework 1. Next, another surface plate 2 is placed on the surface plate 2 and similarly fixed to the frame 1 with screws 12 and bolts 8, and a plurality of surface plates 2 are sequentially attached in the same manner. Thereafter, the heat insulating material 10 is provided inside the framework 1, and the interior base material 11 is attached to the back surface of the framework 1.

According to this embodiment, the front plate 2 is attached to the frame 1 by using both screws and bolts. Therefore, even if the screws 12 become ineffective in an earthquake or the like, the bolts 8 are used. The falling off of the face plate 2 can be prevented. In addition, the bolt 8 is used as a safety measure when the screw 12 becomes ineffective as described above, and can be basically a low-cost screw stop, so that an increase in manufacturing cost can be suppressed.

Further, since the front plate 2 is fixed from both front and back sides by the bolts 8 and the screws 12, the mounting of the front plate 2 is reliable and the durability is improved. Further, since only the inconspicuous screwing is performed from the front side of the face plate 2, the appearance is not impaired. Further, since the screwing is performed from the front side of the face plate 2 as described above, when the face plate 2 is attached to one flange of the channel steel constituting the framework 1, the other flange is not obstructed. Therefore, the screwing operation can be easily performed regardless of the cross-sectional shape of the backside framework 1.

Further, screwing is performed at the position of the middle crosspiece 4 of the frame 1, and the corners of the surface plate 2 that are easily cracked are always removed, so that cracks at the corners of the surface plate 2 can be prevented. Further, since the bolting is performed on the outer peripheral frame 3 of the framework 1 via the plate 5, the plate 5 can cope with expansion and contraction and deformation of the surface plate 2 or the framework 1 by absorbing the external force. it can. Further, a support plate 9 is provided on the lower surface of the lower frame 3b of the framework 1.
Is attached, and the lower surface of the surface plate 2 is supported by the support plate 9, so that the support of the surface plate 2 is in a stable state, and it can be reliably prevented from falling off. Further, when the surface plate 2 is attached to the framework 1, the surface plate 2 can be positioned by the support plate 9, and workability is improved.

4 and 5, the numbers of the surface plates 2 and the plates 5 are different from those in FIG. 1, but any number may be used.

[0017]

According to the concrete outer wall of the present invention, the surface plate is attached to the framework by using both screws and bolts. Therefore, even if the screws become ineffective in the event of an earthquake or the like, the bolts are displayed with bolts. The falling off of the face plate can be prevented. Further, the bolt is used as a safety measure when the screw does not work as described above, and the screw can be basically used as a low-cost screw stop, so that an increase in manufacturing cost can be suppressed. Also, bolt from both sides of the front plate

According to the second aspect of the present invention , the screwing is performed at the position of the middle crosspiece of the framework, and the corners of the surface plate that are easily broken are always removed, so that the corners of the surface plate can be prevented from being cracked. In addition, since bolting is performed on the outer peripheral frame of the framework via a plate, against expansion and contraction, deformation, etc. of the surface plate or the framework,
The plate can absorb and cope with external forces. According to the third aspect , the support plate is attached to the lower surface of the lower frame, and the lower surface of the surface plate is supported by the support plate. Therefore, the support of the surface plate is in a stable state, and the falling off of the support is reliably prevented. be able to. Further, when the surface plate is attached to the framework, the surface plate can be positioned relative to the support plate, and the workability is improved.
