Description

[Detailed Description of the Invention] The present invention relates to a board mounting plate, and particularly to a board mounting plate with improved sound insulation effect.

Conventionally, in order to improve sound insulation and vibration absorption, reduce costs, and eliminate the complexity of work in partitions using dry construction methods,
A board mounting plate as shown in the figure has been proposed.
In the figure, board mounting plates 2, 2 are attached to the top and bottom of the column 1 so as to bridge between the columns 1, 1, and a board 3 is attached to the surface side of the board mounting plates 2, 2. As shown in FIG. 2, the mounting plate 2 includes a fixing plate 5 fixed to the column 1 with screws 4, and a long hole 6 that stands up from one end of the fixing plate 5 to be spaced apart from the column and for preventing vibration transmission.
a mounting plate 9 which is bent from one end of the rising plate 7 so as to be parallel to the fixing plate 5 and to which the board 3 is attached with screws 8, etc.; and one end of the mounting plate 9. and an inclined portion 10 formed by bending the support column 1 toward the support column 1 side. Note that the tip of the inclined portion 10 is separated from the support 1.
By using such a board mounting plate 2, a space E is formed between the support column 1 and the board 3, and this space E provides much better sound insulation and vibration absorption than when the board 3 is directly attached to the support column 1. will improve.

However, according to the conventional board mounting plate 2, since the fixing plate 5 is a flat surface, the supporting column 1
Since the contact area between the support column 1 and the fixed plate 5 is large, the slight vibrations generated in the board 3 by the support column 1 and the fixed plate 5 may be transmitted to the support column 1 side, or vice versa. However, there was a drawback in that slight vibrations were generated in the board 3 due to vibrations on the side of the support column 1. Further, since the fixing plate 5 is in surface contact with the support column 1, the screws 4 are rotated at the final stage of tightening, and the screw holes are enlarged, making it impossible to attach the support plate especially when the plate thickness of the support column is thin.

The purpose of the present invention is to provide a board mounting plate as described above with a protrusion that protrudes in the direction of the support column along the direction in which the screw holes are arranged so as to sandwich the screw holes provided along the longitudinal direction of the fixing plate. This method eliminates each of the above-mentioned drawbacks, and will be explained in detail below using examples.

3 to 5 are simplified configuration diagrams showing one embodiment of the board mounting plate according to the present invention, and in the figure, the board mounting plate 12 is made by bending a long plate material, Holes 13 for fixing with screws 4 are drilled in the column 1 at appropriate intervals along the longitudinal direction, and screw holes 13 are formed so as to sandwich the holes 13.
protrusions 1 that protrude in the support column 1 direction along the arrangement direction of
4, 14, and this fixing plate 15
A rising plate 17 stands up from one end so as to be spaced apart from the pillar 1 and has a long hole 16 for transmitting and absorbing vibrations in the longitudinal direction, and the standing plate 17 is bent from one end of the rising plate 17 in parallel with the fixing plate 15 to hold the board. It is composed of a mounting plate 19 to be attached, and an inclined portion 20 formed by bending the mounting plate 19 in the direction of the support column 1.

In the above configuration, the board mounting plate 12
To attach it to the support column 1, holes 13 are formed in the fixing plate 15 at a constant pitch, so even if the spacing between the support columns 1 and 1 is uneven, you can use any screw hole 13 and fix it with the screw 4. can do. In addition, since the protrusions 14, 14 are formed, a gap g occurs between the central part of the fixed plate 15 and the pillar 1, and when the screw 4 is tightened, the central part and the pillar come together due to the tightening force. Since no rounding occurs, the screw hole is not enlarged, and the tightening effect can be improved. Furthermore, since the fixing plate and the support column, which were conventionally in surface contact, are now in line contact, it is possible to reduce the transmission of vibration and sound generated between the board 3 and the support support 1. Further, if the holes 13 are drilled and arranged at a constant pitch, it is not necessary to form the holes according to the distance between the supports 1, 1, thereby improving workability.

As explained above, according to the board mounting plate according to the present invention, there is a fixed plate that is screwed to the pillars so as to bridge between the pillars, and a rising plate that rises from one end of the fixed plate so as to be spaced apart from the pillars. and a mounting plate that is bent parallel to the fixed plate from one end of the rising plate to which the board is attached, and a screw hole provided along the longitudinal direction of the fixed plate is sandwiched between the board mounting plates. Since a protrusion is provided that protrudes toward the column along the direction in which the screw holes are arranged, the fixing plate and the surface of the column can be reliably fixed to the column side in a line contact state. Transmission of vibrations from the board side and the support side to the other side can be reduced, and a board mounting plate with excellent sound insulation and vibration absorption properties can be obtained. Furthermore, since the holes are arranged at a constant pitch, the installation work can be speeded up.
