[0008]

【Example】

 This invention will be described in detail with reference to the embodiments shown in FIGS. In the figure, 11 is a lower sound field panel, and 12 is an upper sound field panel. These sound field panels are made of non-combustible board and laminated on top of the back plate 13 (sound absorbing panel, reverberation panel, perforated fiber board, non-perforated fiber board, etc.) with three layers of calical boards. The frame 14 is assembled, glass wool 15 (see FIG. 2) is packed in the frame 14, and a non-combustible cloth 16 is attached to the front side.

Reference numerals 17 and 18 denote a receiving metal fitting and a mounting metal fitting formed by extrusion molding of aluminum. The receiving metal fitting 17 is composed of a square seat piece 19 and a mounting piece 20 which is vertically integrally formed on the upper and lower sides of its rear side. The metal fitting 18 comprises an installation piece 21 and an L-shaped piece in which a mounting piece 22 is integrally formed on the rear side thereof.

A ridge 23 is formed on the upper surface of the seat piece 19 so as to project laterally. The mounting piece 20 is composed of a lower piece 20a having the same width as that of the seat piece 19, and a quadrilateral upper piece 20b which is narrower than the lower piece 20a and is formed so as to be biased toward the rear side. An inner corner portion 24 is formed on the rear side of the seat piece 19 by the piece 20b.

On the lower surface of the installation piece 21 of the installation metal fitting 18, a recessed groove 25 that fits with the convex strip 23 is provided laterally with a part of the installation piece 21 curved upward. A panel support piece 26 is provided on the upper surface of the installation piece 21 on the attachment piece side so as to project in parallel with the raised portion.

Further, the lower piece 20a and the upper piece 20b of each metal fitting and the mounting piece 22 are provided with a mounting hole, and the receiving metal fitting 17 is mounted on the panel side with a screw screw inserted into the mounting hole. The mounting brackets 18 can be attached to the panel side on both the frame side.

The receiving bracket 17 and the installation bracket 18 as described above come into contact with predetermined positions of the frame body 14 from the back side when the sound field panel is assembled, and in the receiving bracket 17, the upper edge of the sound field panel 11 in the lower stage. The seating plate 19 is mounted upward, and the mounting bracket 18 is mounted on the lower edge of the upper sound field panel 12 with the mounting piece 21 facing downward. The mounting bracket 18 is attached to one side edge of the field panel 11 and 12 and the other side edge at the same position.

Further, the joint edge of each sound field panel 11, 12 is formed on the step portion 27 by the metal fitting so that there is no gap between the sound field panels, and the step portion 27 causes the seat plate 19 and the installation piece 21 to be installed. And so as to be flush with the edge of the front plate 13. The step portion 27 is formed by shifting the frame body 14 inward by a required dimension, but in some cases, the required portion may be partially cut to form the step portion.

The sound field panels 11 and 12 are built in the lower stage first. As shown in FIGS. 4 and 5, a mounting frame 29 is already framed inside the outer wall 28, a C-shaped bracket 30 is installed on the floor, and an edge member 31 is installed on the upper part of the wall. Therefore, the lower sound field panel 11 is first built on the C-shaped metal fitting 30, and the upper piece 20b of the receiving metal fitting 17 is screwed to the mounting frame 29 to fix the sound field panel 11.

Next, the sound field panel 12 of the upper stage is built on the lower stage, the convex strip 23 of the receiving metal fitting 17 and the groove 25 of the mounting metal fitting 18 are fitted together, and the mounting metal fitting is installed inside the upper piece 20b. The side portions of the mounting pieces 22 of 18 are brought into contact with each other, and the lower corners of the mounting pieces 22 are housed in the inner corner portions 24. Thereafter, the upper sound field panel 12 is fixed by screwing the upper piece 20b of the receiving metal fitting 17 on one side edge to the mounting frame 29. In addition, 32 shows a skirting board.

It is not necessary to fix the sound field panels 11 and 12 to the mounting frame 29 for all the parts built inside the outer wall 28, and as shown in FIG. All that is required is to fix the sound field panels 11A and 12A that have been installed and the sound field panels 11N and 12N that have been installed at the end.

Even in such a case, the sound field panels adjacent to each other in the vertical and horizontal directions are joined to each other with their edges being in contact with each other by the fitting between the receiving metal fitting 17 and the mounting metal fitting 18 and without any external pressure. It doesn't fall off.

Furthermore, since the convex strip 23 and the concave groove 25 fitted to each other serve as a guide against the lateral movement, the fitting is used to move the upper sound field panel 12 to the upper piece 20b. It can be slid inward until the mounting piece 22 of the mounting bracket 18 hits, and can be installed on the lower stage.

[0020]

[Effect of the device]

 As described above, the present invention uses the seat piece 19 having the convex strip 23 provided on the upper surface thereof and the upper piece 20b integrally formed above and below the rear side of the seat piece 19 and narrower than the lower piece 20a. On the rear side, a receiving metal fitting 17 including a mounting piece 20 having an inner corner 24 formed on the rear side and a recessed groove 25 fitted to the convex strip 23 are provided on the lower surface of the installation piece 21. A mounting bracket 18 integrally formed with a mounting piece 22 is attached to the edge of the sound field panel that needs to be joined, and the sound field panels are joined and fastened to the mounting frame through these brackets. Therefore, the following effects are obtained.

Since the sound field panels are joined to each other via the receiving metal fittings having the convex ridges and the concave groove fitting to each other and the installation metal fittings, the level of the jointing portion is always constant as long as the panel dimensions are the same. Of course, there is no gap between the panels, and since there is no difference in height between adjacent panels, the top edges are flush with each other.

The ridge and the groove are fitted to each other only by assembling the upper sound field panel to the lower sound field panel, and the lower corner of the mounting piece is fitted to the inner corner. Due to this, displacement of the upper tier in the front-rear direction and lateral direction is prevented, and the alignment of the sound field panels at the time of joining can be performed using the fitted ridges and grooves as guides, which facilitates the work. In addition, since it is possible to easily extend upwards, it is possible to install sound field panels on high walls.

Since the sound field panels are joined to each other by fitting the ridges and the groove, it is necessary to fix the sound field panels to the mounting frame on all the sound field panels built therein. Instead, it is fixed only by performing it at each key point, so the number of fastening points is smaller than before and the work efficiency is improved. As a result, construction cost is reduced and labor is saved.

-The material composition of the sound field panel can be made of non-combustible material, which enables construction in a non-combustible destination.
