DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a sound absorbing cylinder suitable for mounting a sound absorbing cylinder on a lower surface of an elevated road or the like.

[0002]

2. Description of the Related Art When mounting a sound absorbing cylinder on a lower surface of an elevated road or the like, it is usual to fix both ends of the sound absorbing cylinder one by one between bolts made of H-shaped steels installed at predetermined intervals. . However, this method has a problem that it takes a lot of trouble to fix the sound absorbing cylinders one by one.

Accordingly, the present inventors have previously mounted a plurality of sound absorbing cylinders 1 on a frame 2 in parallel on the ground as shown in FIG. 6 to form a panel, and installed the panels at predetermined intervals as shown in FIG. The method of installation between the beams 3 is under study. In this method, the mounting period 4, which is provided vertically at both ends of the panel, is bolted to the vertical plates 5, 5 on the beam side, thereby shortening the construction period as compared with the conventional method in which one is fixed one by one. Can be.

However, since the interval between the beams 3 is generally as long as about 2 m, the sound-absorbing cylinder 1 becomes considerably heavy, and when a plurality of panels are formed into a panel, the total weight becomes extremely large. Therefore, as shown in FIG.
It has been found that it is not easy to align the bolt holes 6 of 4 with the bolt holes 7 of the vertical plates 5 and 5 on the beam side and fix them together through bolts. In addition, since this work is performed at a high place, accidental dropping of a bolt or the like may cause an accident.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and provides a method of mounting a large number of sound absorbing cylinders between beams installed at predetermined intervals. A first object is to provide a construction method. A second object of the present invention is to provide a method of mounting a sound absorbing cylinder without the risk of accidentally dropping a bolt or the like.

[0006]

According to the present invention, which has been made to solve the above-mentioned problems, a plurality of sound absorbing cylinders are arranged in parallel to form a panel when mounting a sound absorbing cylinder between beams installed at predetermined intervals. In addition, the bent portion at the upper end of the mounting plate provided vertically at both ends of the panel is hooked on the upper part of the vertical plate provided on the beam side, and then the mounting plate is fixed to the beam side. . Opening / closing fixtures are attached to the panel mounting plate, and the bent part at the upper end of the panel mounting plate is hooked to the vertical plate provided on the beam side. By doing so, safe construction is possible.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in more detail with reference to the drawings. FIGS. 1 to 3 show a first embodiment of the present invention. Reference numeral 1 denotes a sound absorbing tube, a plurality of which are arranged in parallel as shown in FIG. 6 to form a panel, and frames are provided at both ends in the longitudinal direction. 2 is attached. Reference numeral 8 denotes a mounting plate provided vertically near both ends of the frame 2 in the width direction. At the upper end of the mounting plate 8, a bent portion 9 is formed downward as shown in FIG. On the other hand, 3 is a beam installed at a predetermined interval, and 10 is a beam 3
Is a vertical plate fixed by welding. This vertical plate 10
Is provided at a position corresponding to the mounting plate 8 of the frame 2 described above.

In order to attach the sound absorbing cylinder 1 to the beam 3 by the method of the present invention, the sound absorbing cylinder 1 which has been made into a panel in advance is connected to the beam 3.
Then, the bent portion 9 at the upper end of each mounting plate 8 is hooked on the upper portion of the vertical plate 10 provided on the beam 3 as shown in FIG. Thereby, the weight of the paneled sound absorbing cylinder 1 can be given to the beam 3. Therefore, the operator may pass bolts through the bolt holes 11 provided in the mounting plate 8 and the vertical plate 10 to fix the panel to the beam 3 side. According to this method, a plurality of sound absorbing cylinders 1 can be attached at the same time, so that the work can be performed quickly. Further, since it is not necessary to tighten bolts while supporting the weight of the sound absorbing cylinder 1, the work is facilitated. There are advantages.

[0009] However, in the above-mentioned method, it is necessary to pass a bolt through the bolt hole 11 and fix the bolt. FIG. 4-
FIG. 5 shows a second embodiment of the present invention in which this point is further improved, and an opening / closing type fixture 12 is attached to a panel-side attachment plate 8 as shown in FIG. This fixture 12
A U-shaped recess 15 is provided at the end of an opening / closing plate 14 that can be opened and closed by a hinge 13, and a bolt 16 extending from a bolt hole of the mounting plate 8 is provided.
Are fitted in the U-shaped recess 15.
Further, a protruding portion 17 having the same width as that of the fixture 12 is provided at the tip of the vertical plate 10 on the beam 3 side.

If this structure is used, first, the opening / closing plate 14 is opened outward so as not to obstruct the work, and the sound absorbing cylinder 1 which has been panelized in advance as described above is connected to the beams 3, 3
5, the bent portion 9 at the upper end of each of the mounting plates 8 is projected into the projecting portion 17 of the vertical plate 10 provided on the beam 3 as shown in FIG.
Hook on top of After that, the opening / closing plate 14 is closed so as to sandwich the projecting portion 17 of the vertical plate 10, the bolt 16 is fitted into the U-shaped recess 15 at the tip of the opening / closing plate 14, and the nut is tightened. As a result, the mounting plate 8 is fixed to the vertical plate 10 on the side of the beam 3 by the opening / closing fixture 12. Moreover, in this case, the bolts 16 can be passed through the bolt holes on the mounting plate 8 side in advance, so that there is no danger of the bolts 16 being accidentally dropped during the mounting operation of the sound-absorbing cylinder 1, which is safe.

In any case, the sound-absorbing cylinder 1 can have an arbitrary structure. The sound-absorbing cylinder 1 may be formed in a cylindrical shape, or may be filled with a fibrous sound-absorbing material.
As shown in FIGS. 1, 4, 6, and 7, a sound-absorbing scaffold plate 18 may be integrally provided on the upper surface of the sound-absorbing cylinder 1. Such a scaffold plate 18 constitutes a continuous scaffold when the sound absorbing cylinder 1 is formed into a panel, and can be used as a scaffold for subsequent maintenance work or the like.

[0012]

As described above, according to the sound absorbing cylinder mounting method of the present invention, since a plurality of sound absorbing cylinders can be mounted on a panel and mounted, the construction period can be shortened. Moreover, since there is no need to perform the fixing operation while supporting a heavy panel, the operation is facilitated. Claim 2
According to the invention, there is an advantage that the work can be performed more safely without fear of dropping the bolt during the work.
