BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a sound absorbing material used in a sound absorbing structure such as a cooling tower or a building.

[0002]

2. Description of the Related Art As a sound absorbing material mounting structure for pressing a sound absorbing material with a wire mesh, there is a ventilation monitor described in Japanese Utility Model Publication No. 52-41977 and a cell silencer disclosed in Japanese Utility Model Publication No. 56-38557. These are related to the shape for sound absorption and not to the detailed attachment of the wire mesh itself, but generally, as shown in FIG. 1b is fixed, the sound absorbing material 3 of, for example, slag wool or rock wool is arranged between the grooved steels 1a and 1b, the sound absorbing surface side of the sound absorbing material 3 is covered with a wire net 4, and the wire net 4 is formed of the grooved steels 1a and 1b. Many means of directly joining to the side surface by welding E are adopted.

[0003]

[Problems to be solved by the invention] However, this requires installation by welding on site and disassembly work by gas cutting, which involves work using fire, so construction requires welding machines, gas cutting machines, and fire curing. The implementation of the measures was complicated.

That is, when the sound absorbing performance is deteriorated due to the moisture absorption of the sound absorbing material 3 itself or when the wire mesh 4 is corroded and deteriorated, the welded wire mesh is once gas-cut and removed, and the wire mesh is removed after the replacement work. The work of welding and joining had to be performed again, and it took a long time to attach and detach.

The present invention is to install and replace the sound absorbing material,
(EN) Provided is a sound absorbing material mounting structure which can be disassembled easily and in a short time.

[0006]

According to the present invention, a sound absorbing material is arranged between a plurality of sound absorbing material receiving members which are horizontally fixed to a wall body, and a wire net covering the sound absorbing surface of the sound absorbing material is provided as a sound absorbing material receiving member. In the sound absorbing material mounting structure locked in between, the rear end of the bolt is fixedly arranged at a predetermined interval in the longitudinal direction of the sound absorbing material receiving member, the tip of the bolt is projected to the front side from the sound absorbing surface, and the reinforcing bar of the sound absorbing material is fixed. It is characterized in that it is abutted on the front wire mesh and is arranged on both sides with a bolt sandwiched between a plurality of bolts, and the reinforcing bar is held down by a reinforcing bar holding metal object having a bolt through hole in the center and a nut screwed to the bolt It is a sound absorbing material mounting structure.

[0007]

[Function] Since the wire mesh covering the sound absorbing material is pressed against the sound absorbing material receiving member by the bolts and nuts through the reinforcing bar pressing metal and the reinforcing bar, the wire mesh and the sound absorbing material can be easily attached and detached in a short time. . Furthermore, since reinforcing bars are used, the reinforcing bars can be bent and aligned even if the bolts are not aligned in a straight line in the laying direction of the reinforcing bars.
There is no need to perform complicated work such as changing the mounting position of the bolt.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing an embodiment of the present invention.

Channel steels 1a and 1b as sound absorbing member receiving members are horizontally fixed to the wall 8 at predetermined intervals in the height direction. The rear ends of the bolts 2a and 2b are previously welded to the flange surfaces of the channel steels 1a and 1b at the factory. The vinyl 3a covers the surface of the sound absorbing material 3 in order to prevent the sound absorbing material 3 such as slag wool from absorbing water. A wire mesh 4 having a mesh size of 100 mm is arranged on the front surface of the sound absorbing material 3 on the sound absorbing surface A side to prevent the sound absorbing material 3 from falling out between the channel steels 1a and 1b. Two reinforcing bars 5 are arranged in the vertical direction along the arrangement of the bolts 2a and 2b, and hold the wire mesh 4 so as not to tilt toward the sound absorbing surface A side of the sound absorbing material 3.

As shown in FIG. 2, the reinforcing bar retainer 6 has a concave cross-section and has a through hole for the bolt in the center and a cavity into which the reinforcing bar 5 can be inserted on the left and right sides thereof. 2a, the rebar 5 is fixed to the channel steel 1a with the nut 7. The nut 7 is for fixing the reinforcing bar pressing metal 6 to the bolt 2a, and the reinforcing bar 5 is engaged with both sides of the reinforcing bar pressing metal 6,
By inserting the bolt 2 into the through hole and screwing it into the nut 7 and tightening it, the wire net 4 is pressed against the sound absorbing material 3, and the sound absorbing material 3 is fixed and does not swell outward.

The rebar may be made of round steel, square steel or the like, and a diameter of about 9 mm is preferable in terms of work.

Further, in this embodiment, the reinforcing bars are provided so as to intersect with the channel steel, but the present invention is not limited to this, and they may be provided in parallel with the channel steel.

[0013]

EFFECTS OF THE INVENTION According to the present invention, it is possible to eliminate the work of using fire such as welding and gas cutting from the on-site work when attaching and detaching the sound absorbing material and the wire net, and the workability is improved. Furthermore, even if there is a construction difference in the position of the bolts, it is easy to bend the reinforcing bars to match the bolt arrangement, so complicated work such as changing the bolt position is unnecessary, and the work can be done in a short time.
