The present invention supports a sound absorbing board having a predetermined thickness arranged in a gap formed by being surrounded by a structure composed of a plurality of column members and a plurality of beam members and being surrounded by the column members and the beam members. It relates to a panel support structure.

A structure composed of a plurality of column members and a plurality of beam members is used.
For example, a structure composed of a plurality of column members and a plurality of beam members is used as part of a mechanical device.
When machinery generates noise and vibration, it is required not to radiate noise and vibration to the outside.
Therefore, it is attempted to fix a sound absorbing board having a predetermined thickness arranged in a gap formed by being surrounded by a column member and a beam member.

For example, a mechanical device containing a press device has a structure composed of a plurality of column members, a plurality of beam members, and an engine section.
For example, a sound absorbing board has a structure in which a glass wool layer is sandwiched between punching metals.
A panel support structure supports the acoustic board on the basis of the structure.
The panel support structure is desired to support the sound absorbing board so as to suppress the radiation of vibration and noise generated by the engine section to the outside.

In mechanical devices, vibrations and noise generated by the engine part are radiated to the outside by air propagation and solid propagation.
Therefore, it is desired that the panel support structure can suppress the air propagation and solid propagation of vibrations and noise generated by the engine section.

The present invention has been devised in view of the above-described problems, and is based on a structure composed of a plurality of column members and a plurality of beam members in a simple and efficient manner. To provide a panel support structure capable of suppressing radiation of vibration and noise by supporting a sound absorbing board having a predetermined thickness arranged in a space formed by enclosing.

In order to achieve the above-mentioned object, a structure composed of a plurality of column members and a plurality of beam members according to the present invention is used as a foundation, and predetermined gaps are formed by being surrounded by the column members and the beam members.

As described above, the panel support structure according to the present invention has the following effects due to its procedure and configuration.
The outer periphery of the sound absorbing board is surrounded by a frame-like frame, and when the panel fixed to the surface of the frame-like frame is installed in the structure, the gap between the outer edge of the frame-like frame and the column member and the beam member is covered so as to hide the gap, When a plurality of mounting brackets, which are plate-like members having a pair of bent portions in one direction and the other direction, are installed on a structure, the ends on one side from one bent portion are defined as column members and beam members. Since the end portion on the other side from the other bent portion is fixed to the back surface of the frame-shaped frame by abutting on the back surface, it passes through the gap between the outer edge of the frame-shaped frame and the column member and the beam member. Air propagation through the panel can be suppressed, and vibrations are less likely to be transmitted to the panel, and solid propagation passing through the panel can be suppressed.
When the mounting bracket is installed on a structure, the end on the one side from one bent portion is brought into contact with the back surface of one of the column member and the beam member, and the end on the other side from the other bent portion is attached. Since the portion is fixed to the back surface of the frame-shaped frame, it is possible to suppress the propagation of air passing through the gaps between the outer edge of the frame-shaped frame and the column members and beam members. Solid propagation can be suppressed.
Since the plate member made of elastic material is sandwiched between the surface of the column member or the surface of the beam member and the back surface of the panel facing the surface, the vibration of the column member and the beam member is transmitted to the panel. It is difficult to suppress solid propagation through the panel.
Since a plurality of mounting brackets are fixed with bolts to the female screws formed in the frame-shaped frame at the ends in the other direction from the other bent portions, the vibrations of the column members and beam members are transmitted to the frame. It is difficult to suppress solid propagation through the panel.
One end of the bendable long member is fixed to a column member or beam member, and the other end is fixed to a sound absorbing board. It can prevent unexpected falling off.
Therefore, with a simple structure, it has a predetermined thickness that is arranged in the gap formed by being surrounded by the column members and the beam members based on the structure composed of the plurality of column members and the plurality of beam members. It is possible to provide a panel support structure capable of fixing a sound absorbing board and suppressing radiation of vibration and noise.
