The operation and effect of the preferred configuration will be described in the next section.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 exemplifies a sound absorbing wall 1 provided on a road excavation. The sound-absorbing wall 1 is constructed by attaching a horizontally long sound-absorbing plate 2 (panel) to the outside of the concrete surface W of the digging by using the fixture 10 of the present invention, as shown in FIG. . As the sound absorbing plate 2, a material in which a nonwoven fabric and glass wool serving as a sound absorbing material are filled in a box-shaped panel formed of an aluminum punched plate is used.
[0014]
FIG. 3 shows details of the fixture 10. The attachment 10 includes three types of frames having substantially the same length as the sound absorbing plate 2, that is, an uppermost fixed frame 11, and upper horizontal frames 12 respectively attached to upper edges of the sound absorbing plates except for the uppermost sound absorbing plate. And a lower horizontal frame 13 attached to the lower edge of the sound absorbing plate of each stage. Assuming that the number of stacked sound absorbing plates 2 is N, the lower horizontal frame 13 is combined with N and the upper horizontal frame 12 is combined with (N-1). Regarding the uppermost fixed frame 11, the number of combinations per set is one, regardless of the number of stacked stages of the sound absorbing plates 2.
[0015]
The uppermost fixed frame 11 is composed of a frame 11a having an inverted U-shaped cross section, and a mounting portion 11b provided on the back surface at positions near both ends of the frame. The groove 11c in the downward opening of the frame 11a is a groove for fitting the panel. The mounting portion 11b was formed by bending a plate to be welded to the frame 11a to form a hanging portion at a position receded by a predetermined length from the back surface of the frame 11a, and provided a horizontally long mounting hole h in the hanging portion. Is not limited to the illustrated one.
[0016]
The upper horizontal frame 12 is provided with a locking tool 12b projecting upward on the back surface of a frame 12a having an inverted U-shaped cross section. The groove 12c in the downward opening of the frame 12a is a groove for fitting the panel. A plate is welded to the back surface near both ends of the frame 12a and used as the locking tool 12b. The locking surface of the locking tool 12b is in the same plane as the rear surface of the frame 12a. Further, the locking tool 12b is provided at a position where interference between the uppermost fixed frame 11 and the mounting portion provided on the lower horizontal frame 13 can be avoided. Depending on the length of the sound absorbing plate 2, the number of the locking members 12b may be reduced to one or may be increased to two or more.
[0017]
The lower horizontal frame 13 is composed of a frame 13a having a U-shaped cross section and a mounting portion 13b provided on the back surface at positions near both ends of the frame. The groove 13c in the upward opening of the frame 13a is a groove for fitting the panel. The mounting portion 13b is the same as the mounting portion provided on the uppermost fixed frame 11, and has a horizontally long mounting hole h in a hanging portion at a position receded from the back surface of the frame 13a by a predetermined length. If the height of the rear wall surface of the frames 11a, 12a, 13a is higher than that of the front wall surface as shown in the figure, the panel can be easily fitted.
[0018]
It is preferable that the mounting fixture configured as described above be integrated with the uppermost fixed frame 11 fitted on the upper edge of the uppermost sound absorbing plate 2 and the lower horizontal frame 13 fitted on the lower edge in advance. Also, as shown in FIG. 4, the lower sound absorbing plate 2 (the second and subsequent sound absorbing plates from the top) is fitted with the upper horizontal frame 12 at the upper edge and the lower horizontal frame 13 at the lower edge. It is transported to the construction site and the uppermost sound absorbing plate is attached first.
[0019]
As shown in FIGS. 1 and 5, the anchor bolt 14 planted on the concrete wall W of the digging hole is passed through the mounting holes h of the mounting portions 11b and 13b of the sound absorbing plate for the uppermost step, and is fixed by the lock nut N1 and the tightening nut N2. The mounting portions 11b and 13b are fixed, and the mounting of the uppermost sound absorbing plate 2 is completed. Next, the second-stage sound absorbing plate 2 from the top is attached. The attachment is performed by inserting the locking member 12b of the upper horizontal frame 12 into the back side of the lower horizontal frame 13 of the lower edge of the uppermost panel which has already been fixed, and locking it to the rear surface of the frame 13a. The lower horizontal frame 13 fixed to the sound absorbing plate is fixed to the anchor bolt 14 planted on the concrete wall surface W in the same manner as the lower horizontal frame 13 of the upper sound absorbing plate.
[0020]
Thereafter, the same operation is repeated until the mounting of the lowermost sound absorbing plate is completed.
[0021]
The sound absorbing wall 1 of FIGS. 1 and 2 assembled in this manner has a good appearance because the fixing bolts, locking tools, and mounting portions are hidden behind the sound absorbing plate. When some sound absorbing plates are damaged by collision or contact of the vehicle, the sound absorbing wall 1 is removed from the lower horizontal frame, and the damaged sound absorbing plates are sequentially removed from the lowermost portion and replaced with a new one. In this way, even if the sound absorbing plate is removed from below, the upper sound absorbing plate is supported by the lower horizontal frame fitted to the lower edge of the plate, so the upper sound absorbing plate does not fall down and work safely. Can be.
[0022]
The sound insulation and sound absorbing walls of the road are likely to damage the sound insulation and sound absorbing plates, and the damage is more likely to occur on the lower side. It can be expected to have a particularly great effect when used for mounting panels, but it is suitable for mounting sound insulation walls other than for roads, panels for sound absorption walls, or other panels such as radio wave absorption panels, interior and exterior panels of buildings, etc. Also available.
[0023]
The number of the attachment portions 11b and 13b provided on the uppermost fixed frame 11 and the lower horizontal frame 13 may be two or more.
[0024]
FIGS. 8 to 10 show auxiliary tools provided in consideration of a case where a displacement occurs between the mounting holes h provided in the mounting portions 11 b and 13 b and the anchor bolt 14.
[0025]
The planting position of the anchor bolt 14 may be deviated in the vertical direction from the prescribed position due to the regulation by the reinforcing bar arrangement position. The vertical displacement cannot be absorbed by the horizontally long mounting holes h provided in the mounting portions 11b and 13b.
[0026]
At this time, the auxiliary tool 15 is used. The auxiliary tool 15 is rotated relative to one of the tightening nut N2 and the locking nut N1 which is screwed to the anchor bolt 14 and the auxiliary tool is interposed between the fixing bolt insertion hole 15a, the vertically long fastening bolt insertion hole 15b, and the anchor bolt 14. It is provided with a nut engaging portion (in the figure, a groove) 15c for impermissibly engaging. As shown in FIG. 9, the auxiliary tool 15 is fixed to an anchor bolt 14 passed through a hole 15a, and a fastening bolt 16 passed through holes h and 15b of a long hole and a nut (not shown) screwed thereto. The connecting part 11b (13b) is connected to the assisting tool 15 by using the same. In addition, the auxiliary tool 15 is locked by a nut on which the load of the panel acts in the tightening direction. For example, in the case of FIG. 9, a rotational moment M in the direction indicated by an arrow in the figure is applied to the auxiliary tool 15 by the load of the panel, so that the auxiliary tool 15 is locked to the tightening nut N2. In addition, in the case of FIG. 10, since the rotational moment M due to the load of the panel is opposite to that of FIG. 9, the auxiliary tool 15 is turned upside down and locked to the lock nut N1.
[0027]
【The invention's effect】
As described above, the mounting device of the present invention is composed of three types of frames, and the panels to be mounted in a state of being stacked in a plurality of stages are sequentially mounted downward from the uppermost panel, so that the damaged lower stage is mounted. Panels can be replaced without removing the upper panel, and even if the lower panel is removed, the upper panel does not slip down, and there are fewer bolts to fix, making panel replacement and installation of new panels more efficient. Can do well.
[0028]
In addition, the fixing fastener and the mounting portion do not appear on the surface, and the appearance of the constructed wall is excellent.
[0029]
8 to 10 can also absorb the displacement of the anchor bolt in the vertical, horizontal, and both directions, thereby improving the workability of the panel.
