[0016]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show a first embodiment of a panel and a connecting method according to the present invention. In these figures, a panel 10 has a pair of panel forming plates 10A and 10B arranged in parallel with each other, an elastic body 11 interposed between the panel forming plates 10A and 10B, and a compression of the elastic body 11. And the panel forming plates 10A, 10B
And pressing means 12 for pressing the pressing means in directions approaching each other.

The panel forming plates 10A and 10B are made of plywood. However, these panel forming plates 1
It is preferable that 0A and 10B be made of a material having air permeability and a certain density. Also,
Use cement, gypsum board, calcium silicate plate,
These can be arbitrarily combined to form both surfaces of the panel, thereby making it possible to impart noncombustibility.

The elastic body 11 is adhered to each inner surface or one of the inner surfaces of the panel forming plates 10A and 10B using an appropriate adhesive. In this embodiment, the elastic body 11 is made of a sound absorbing material such as a sponge having open cells, and shrinks its own volume when a pressing force or a pressing force is applied from the outside, while releasing the pressing force or It has the property of expanding to return to the initial volume when it is reduced. The interposition region of the elastic body 11 is shown in FIGS.
As shown in FIG. 5, the elastic members 11 and the panel forming plates 10A and 10B are on the outer peripheral side of the panel forming plates 10A and 10B.
A certain hollow layer is formed inside by the opposing surfaces of A and 10B.

As shown in FIGS. 2 and 3, the pressing means 12 includes a pair of washer plates 15 disposed on the outer surfaces of the panel forming plates 10A and 10B, respectively.
The washer plate 15 and each panel forming plate 10
A, 10B, a plurality of bolts 16 extending through the nuts, and nuts 1 to be screwed into the tip screw regions of the bolts 16, respectively.
7. Therefore, when the screw engagement between the bolt 16 and the nut 17 is released, the elastic body 11 is released from the compressed state and expands, and the respective panel forming plates 10A, 10A,
The relative distance between 10B can be increased.

The interconnection of the panels 10 is performed by a frame 20.
This is performed using As shown in FIG. 1, the frame 20 includes a horizontal rail 21 disposed substantially in parallel along upper and lower edges of the panel 10, and a vertical rail 22 bridged between the horizontal rails 21. The lateral rail 21 is formed with a U-shaped groove 23 that is open to face each other. At this time, the horizontal rail 21 and the vertical rail 22
The connection is performed by bonding at the connection positions or using an appropriate fastener. The vertical separation distance of each horizontal rail 21 is set slightly larger than the height of the panel 10, that is, the vertical length. The opening width of the groove 23 is larger than the entire plate width of the panel 10 in a state where the elastic body 11 is compressed, and smaller than the width when the elastic body 11 expands and the plate width becomes maximum. Is set. Further, the vertical rail 22 has a substantially H-shaped cross section,
A groove 24 is formed which can receive one end of each of the panels 10 that are abutted against each other. At this time, it is preferable that the vertical rail 22 is formed such that the opening width of the groove 24 in the vertical rail 22 is the same as the opening width of the groove 23 of the horizontal rail 21. In addition, in the state of FIG.
Although an aspect in which the panels 10 are connected in a horizontal row is shown,
When connecting the panel 10 to the upper and lower sides, it is sufficient to use a horizontal rail having an H-shaped cross section.

Next, a specific connecting method of the panel 10 according to the first embodiment will be described.

As shown in FIG. 1, the panel 10 is set in a state where the elastic body 11 is compressed by the pressing means 12, and in this state, the panel 10 is set on the horizontal rail 21 constituting the frame 20 by a sliding operation or the like. First panel 10
After being set between the horizontal rails 21, the vertical rail 22 is bridged between the horizontal rails 21, and one end of the panel 10 is received in the groove 24 of the vertical rail 22 located on the right side in FIG. 1. Next, the next panel 10 is set between the horizontal rails 21, and then, if necessary, the vertical rails 22 are similarly set between the horizontal rails 21. At this time, the panel 10 is in a state of being loosely fitted to the frame 20, and free movement is allowed to a certain extent.

After the connection of each panel 10 via the frame 20 is completed in this way, the fastening between the bolt 16 and the nut 17 is released, the washer plate 15 is removed, and the pressing means 12 is removed as a whole. .
At this time, the elastic body 11 that has been compressed until then gradually expands due to its own elastic restoring force, and the expansion causes the panel forming plates 10A and 10B to be separated from each other. Then, panel forming plates 10A and 10B
Is pressed against the respective inner surfaces of the groove 23 of the horizontal rail 21 and the groove 24 of the vertical rail 22. At this time, the free movement of the panel 10 with respect to the frame 20 is restricted. The interconnection of the panels 10 is completed.

After the pressing means 12 has been removed, bolt insertion holes will be exposed in each of the panel forming plates 10A and 10B. The hole is hidden by burying the concealing member.

Therefore, according to such an embodiment, the panel 10 is formed by interposing the elastic body 11 having both actions of compression and expansion between the panel forming plates 10A and 10B, while the panel 10 is formed. Since the frame 20 having the grooves 23 and 24 capable of securely holding the panel 1 is used, the panel 1 can be used without employing any fasteners such as bolts.
0 can be fixed to the frame 20, thereby obtaining an effect that a plurality of panels 10 can be continuously connected.

Further, since the panel 10 is mass-produced in a manufacturing factory or the like in advance and the above-mentioned pressing means 12 need only be removed when the panel 10 is constructed on site, it is necessary to construct a soundproof room or the like using the panel 10. Construction time can be drastically reduced. Moreover, the panel 10 and the frame 20
Is set so as to allow a so-called play between the two, so that it is possible to give a degree of freedom to the design accuracy of the panel 10 such as the plane area and the like, and to achieve the vertical or horizontal accuracy. There is an advantage that the rigor is not required to be as strict as this, and the construction time can be shortened from this point, and the gap is not exposed after the construction is completed.

Further, in this embodiment, the panel forming plate 10
Since the elastic body 11 made of sponge is provided on the outer peripheral side opposing surfaces of A and 10B, the elastic body 11 can produce a sound absorbing action and a solid propagation preventing action, and especially the panel 10 as a building material for a soundproof room or the like. It can be used effectively. Further, in forming the panel 10, a pair of panel forming plates 10A and 10B is used, and a fixed inner region excluding the elastic body 11 is formed as a hollow layer. Can be.

Further, since the pressing means 12 can be removed and collected at the time of construction, the pressing means 12 can be reused, and the modern problem of generation of waste can be solved.
Furthermore, when using the pressing means 12 according to the present embodiment, a plate made of various materials can be used as long as even holes can be formed in the panel forming plates 10A and 10B. In the case where non-rigid ones are used as the panel forming plates 10A and 10B, it is possible to avoid shear failure during compression by backing a plywood or the like around the periphery.

Next, a second embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. In the following description, the same or equivalent components as those of the first embodiment are denoted by the same reference numerals, and the description is omitted or simplified.

In the second embodiment, the panel forming plate 10
A total of eight elongated washer plates 15 parallel to each periphery of A and 10B are used, and these can be individually removed at the time of construction, and the fastening positions by the bolts 16 and the nuts 17 are brought close to the elastic body 11. The insertion holes of the bolts 16 are covered with the grooves 23 and 24 of the frame 20 when the installation of the panel 10 is completed.

At the time of panel connection in this embodiment, as shown in FIG. 5A, one end of the panel 10 is
Is slightly received in the groove 23 or 24. And FIG.
As shown in (B), the pressing force of the pressing means 12 is released to expand the volume of the elastic body 11. At this time, the separation distance between the panel forming plates 10A and 10B is increased, so that the outer surfaces of the panel forming plates 10A and 10B are pressed against the inner surfaces of the grooves 23 and 24. If pressed panel 10 in this state further into the groove, the bolt insertion hole becomes to be covered in the grooves 23 and 24, it is possible to hide the insertion hole from the outside viewing position (FIG. 5 (C) see) .

As shown in FIGS. 6 (A) to 6 (C), the panel 10 is sequentially slid on the lower horizontal rail 21 of the frame 20 to set the panel 10 at a predetermined position, and the panels 10 are adjacent to each other. The pressing means 12 is removed by interposing a vertical rail 22 between the panel 10 and the horizontal means 21. Finally, the upper horizontal rail 21 is fitted from the upper end side of each panel 10 to remove the pressing means 12 left on the upper part. By removing, wall construction can be performed efficiently.

When constructing the ceiling panel, FIG.
As shown in (1), a horizontal rail 21 having an open shape toward the inside may be used, and the panel 10 may be connected to the inner region surrounded by the horizontal rail 21 in the same manner as described above.

Therefore, according to the second embodiment, not only the effect obtained in the first embodiment but also the necessity of hiding the bolt insertion hole after removing the pressing means 12 with a separate member is required. The effect of simplification of construction through the further reduction of the number of parts and an excellent appearance can be maintained.

In the first and second embodiments, the structure in which the pressing means 12 is removed is adopted, but the present invention is not limited to this. For example, the screwed position of the bolt 16 may be retracted without releasing the fastening between the bolt 16 and the nut 17, and if the elastic body 11 is expanded by an amount equal to the retracted amount of the bolt 16, the same as described above is performed. Connection can be performed. In this regard, in consideration of solid propagation, a type in which the pressing means 12 is removed is preferable, but it will be effective for wall construction which does not need to consider soundproofing. The pressing means 12 is constituted by the washer plate 15, the bolt 16, and the nut 17,
If there is no problem in strength, such as when the plane area of the panel forming plates 10A and 10B is relatively small, it is not sufficient to provide the washer plate 15. In some cases, the nut 1
7 is fixed to the inner surface side of the panel forming plate 10B, and the bolt 16 is formed without forming a bolt insertion hole in the panel forming plate 10B.
May be screwed into the nut 17. Further, the pressing means 12 can be replaced with a U-shaped member or the like which can be bridged between the edges of the panel forming plates 10A and 10B. Further, the pressing means 12 can be omitted if necessary. In this case, the panel 10 is
When the elastic body 11 is set to 0, the elastic body 11 may be temporarily compressed by manually applying a pressing force from the outer surface of the panel 10. If the pressing force is released after the setting is completed,
The outer surfaces of the panel forming plates 10A, 10B can be pressed against the inner surfaces of the grooves 23, 24.

Further, the configuration in which a certain hollow layer is provided between the panel forming plates 10A and 10B has been illustrated and described, but the elastic body 1 having the same plane area as each of the panel forming plates 10A and 10B has been described.
In addition to the configuration 1, the configuration in which another sound absorbing material or the like is interposed can also be employed.

Next, a third embodiment of the present invention will be described with reference to FIGS.

The third embodiment has a main feature in that the panel 10 itself can be assembled on site.

As shown in FIGS. 8 and 9, hollow pillars 30 and 31 as frames provided separately from each other in the inside and outside of the groove 23 of the horizontal rail 21 constituting the frame are assembled. The interval between these columns 30.31 in the left-right direction is set to be slightly larger than the left-right width of panel 10. Here, the pillar 3 in the present embodiment
0 is located outside the soundproof room, while the column 31 is used as located inside the soundproof room. A receiving plate 33 having a width larger than the width of the column 30 and having a shorter vertical dimension corresponding to the depth of the groove 23 of the horizontal rail 21 is fixed to the outer surface of the column 30. The pillar 30 and the receiving plate 33
As shown in FIG. 9, it is fixed via a weld 34.

A plurality of screw holes 36 are formed in the outer surface 31A of the inner column 31 along the vertical direction. The outer surface 31A is opposed to the receiving plate 33 and coaxial with the screw holes 36. A pressing plate 37 having a hole 37 </ b> A is provided so as to be fixable by a screw 38. The pressing plate 37 has the same operation as the receiving plate 33. A double-sided adhesive tape 39 is disposed between the inner surfaces of the pressing plate 37 and the receiving plate 33 and the outer surfaces of the panel forming plates 10A and 10B.

In the above configuration, when connecting the panels 10, first, the horizontal rails 21 on the floor side are set, and then the columns 30, 31 are assembled in the grooves 23 of the horizontal rails 21. At this time, a double-sided adhesive tape is previously bonded to the inner surface of the receiving plate 33 fixed to the column 30. The horizontal rail 21 and the columns 30 and 31 are assembled or connected using an adhesive or a fastener such as a bolt.

Next, the first panel forming plate 10A is set so that the outer peripheral side thereof is in contact with the inner surface of the groove 23 of the horizontal rail 21 and the inner surface of the receiving plate 33. At this time, the first panel forming plate 10A is bonded to the double-sided adhesive tape 39. Then, a separate first panel forming plate 10A indicated by a two-dot chain line in FIG. 9 is set at an adjacent position sandwiching the column 30 in a similar manner. Thereafter, the second panel forming plate 10B is pressed against the first panel forming plate 10A together with the elastic body 11 to form the first panel forming plate 10A.
Is pressed so that the lower edge is received in the groove 23. At this time, it is preferable that the elastic body 11 is previously bonded to the inner surface side of the second panel forming plate 10B. A separate second panel forming plate 1 is also provided at a position adjacent to the second panel forming plate 10B.
0B is set similarly. Then, the pressing plate 37 extends over the relative edges of the second panel forming plates 10B, 10B.
And screw 38 through the pressing plate 37 to the column 31
Tighten. Thereafter, the horizontal rail 21 is mounted so as to cover the horizontal rail 21 from above, and the horizontal rail 21
Is fixed.

Thereafter, similarly, the columns 10 and 31 can be appropriately added and the panels 10 can be sequentially connected. When the assembly is completed, each panel forming plate 10A, 10B
Are pressed against the respective inner surfaces of the groove 23, the receiving plate 33 and the pressing plate 37.

Therefore, according to the third embodiment, since the panel 10 is assembled at the site, when the panel 10 has a large or heavy structure, the panel forming plates 10A and 10B are combined. As a result, the work load can be reduced.

The configuration shown in FIG. 8 shows an example in which the panel 20 is used as a wall of a soundproof room or the like, and the same configuration can be applied to a floor surface or a ceiling surface. In this case, the columns 30 and 31 are
It will act as a crosspiece spanned between the two.

Also, on the inner surface side of the pressing plate 37, FIG.
As shown at 0, a configuration may be adopted in which a channel member 42 having a U-shaped groove 41 is fixed, and the column 31 can be accommodated in the U-shaped groove 41. According to this configuration, the relative positioning of the pressing plate 37 with respect to the column 31 can be performed extremely and reliably.

Further, the elastic body 10 in each of the above embodiments is not limited to a sponge, and may be glass wool coated with a moisture-resistant and alkali-resistant film, for example, and can be appropriately changed. For example, as shown in FIG. 11A, a rubber plate 45 is bonded to the first or second panel forming plate 10A, 10B, and the rubber plate 45 and the second panel forming plate 1 are bonded.
It is possible to interpose a spring 47 between the spring 47 and OB.
Of course, the rubber plate 45 and the spring 47 may be arranged in reverse. Here, the spring 47 may be a coil spring or a leaf spring. The first and second panel forming plates 1
It is also possible to arrange the sponge 45 slightly inside the outer peripheral edge between 0A and 10B, and to fill the outside of the sponge 45 with a sound absorbing material such as glass wool 48. With such a configuration, a non-combustible effect can be imparted.

An experimental example employing the configuration of the above embodiment is shown below together with a comparative example. Here, the panel forming plate used in Experimental Example 1 had a thickness of 9 mm and 12 mm, and the elastic body used was a polyurethane foam (UEV) having a thickness of 24 mm when expanded. Further, glass wool having a thickness of 25 mm and 80 kg / m ³ was filled as a sound absorbing material in an inner space surrounded by each panel forming plate and the elastic body. In Experimental Example 2, a panel obtained by removing only glass wool from the panel of Experimental Example 1 was employed.

In Comparative Example 1, a wooden frame was used instead of the elastic body. Other conditions are the same as in the experimental example.

FIG. 12 shows the sound insulation performance of Experimental Examples 1 and 2 and Comparative Example 1.

As shown in the graph of FIG. 12, it is clear that even when the panel according to the present invention and the method of connecting the panel are employed, the sound insulation performance is generally superior to that of the comparative example and practicality is provided. .
