た。 Conventionally, the connection method using this sound insulation sheet was
As shown in the figure, the sound insulation sheet 2 was attached to the sound insulation board 1 by gluing or using screws, nails, etc., but due to the relatively weak sound insulation sheet and the large weight of the sound insulation board, this connection was difficult. It was easy to apply a lot of force, which caused many problems. That is, there are problems such as adhesive peeling, partial damage or deformation of the screw part, and accompanying sound leakage. Furthermore, since the weight of the sound insulating plate is large, there is a serious problem that the folding operation is not safe.

である。``Problems to be Solved by the Invention'' The present invention provides a new and useful connection unit that solves the above-mentioned problems. In other words, it improves the durability and reliability of the most important connecting parts of a foldable soundproof room, prevents damage and sound leakage, and
The purpose is to ensure the safety of folding operations.

あればよい。"Means for Solving the Problems" The present invention will be described in detail below based on the drawings. FIG. 3 shows an embodiment of the connecting part of the sound insulating board according to the present invention, in which a cut-out tubular body 3 is provided at the connecting part of the sound insulating board 1, a core material 5 is wrapped with a sound insulating sheet 2, and the tubular body The sound insulation board is inserted into the inside of the board to connect the two sound insulation boards. The opening dimension of the notch 4 of the tubular body is
It is sufficient that the size is sufficiently smaller than the sum of the diameter of the core material 5 and the thickness of the sound insulation sheet 2, and that the sound insulation sheet does not fall out.

管状体の形状は円形に限定されるものでなく、
どのような形状でもよく、遮音板が金属板等で構
成されている場合は、その小口を加工して切り欠
いた管状体に形成してもよい。 The shape of the tubular body is not limited to a circle;
It may be of any shape, and if the sound insulating plate is made of a metal plate or the like, it may be formed into a tubular body with its edges cut out.

又、切り欠き部４の方向は第３図に示すような
横方向と限らず、斜め方向にしてもよい。例えば
上部折りたたみ部は左右側部の上に重ね合せとな

ことによつて、重ね合せ部の隙間を小さくするこ
とが出来る。 Further, the direction of the notch portion 4 is not limited to the horizontal direction as shown in FIG. 3, but may be an oblique direction. For example, since the upper folded portion overlaps the left and right side portions, the gap between the overlapped portions can be reduced by oriented the cutout portion 4 diagonally downward.

遮音シート２は通常６枚重ね程度となるが第３
図は重ね状態を省略した図である。又、遮音シー
トの補強と化粧を目的として、遮音シートの外側
に化粧シートを設けてもよい。 The sound insulation sheet 2 is usually about 6 sheets stacked, but the 3rd layer
The figure omits the overlapping state. Further, a decorative sheet may be provided on the outside of the sound insulation sheet for the purpose of reinforcing and decorating the sound insulation sheet.

芯材５は円形に限らず多角形ものでもよく、長
さ方向が分割されたものでもよい。 The core material 5 is not limited to a circular shape, but may be polygonal, or may be divided in the length direction.

『作用』 管状体３と遮音シート２は芯材５の存在によつ

からネジ釘等と比べると局部的な応力が作用せず
広い面積で応力を受けることになつて強度的に極
めて有利となり、部分的破損や変形を生ずること
もない。``Function'' The presence of the core material 5 generates a frictional force between the tubular body 3 and the sound insulating sheet 2, and this force holds the tubular body 3 and the sound insulating sheet 2 in place.Compared to screws, etc., no local stress is applied and the area is large. It is extremely advantageous in terms of strength as it is subjected to stress and does not suffer from partial breakage or deformation.
