Provided, the frame 3
The ridge 4 for sandwiching and fixing the sound insulation thin plate 2 in the state of being fitted to the frame body 3 is pressed against the frame body 3 along the surface direction of the sound insulation thin plate 2.

破損を防止することができる。According to the above-described conventional sound insulation plate, the ridge is attached to the frame body so as to sandwich the sound insulation thin plate, and at the same time, to apply an external force to the frame body. It is also possible to share the stress with the frame body. For example, as shown in FIG. 5, when an external force is applied to the frame body 3 to which the pushing edge 4 is attached, the frame body 3 and the pushing edge 4 are each deformed into a convex bow in the acting direction of the external force and the external force is applied. Oppose. At that time, in each abutting portion S (formed on a plane) between the frame 3 and the ridge 4, the abutting portion of the frame 3 is deformed in the extending direction, and the abutting portion of the ridge 4 is contracted. However, by suppressing the contradictory deformation of both members 3 and 4, it is possible to reduce the bending of both members 3 and 4, and to prevent the thin plate from being damaged by the bending. .

る。According to the conventional sound insulation plate, it is possible to suppress the opposite deformations of the two members on the contact surface formed on the flat surface.
Since a bolt for joining both members is mainly used, a bolt having a large cross-sectional area is used in order to integrally connect the frame body and the ridge to further reduce bending when an external force acts. It is necessary to use or reduce the bolt installation pitch to provide a large number of bolts.
The area and number of bolt through holes provided in the ridge increases. When the area or number of the bolt through holes in the frame body and the ridge increases, the rigidity of the frame body and the ridge as a member decreases, so that the sectional area of the member itself must be increased, and the weight of the sound insulation plate increases. There is a problem that it becomes difficult to handle because the frame and the ridge become large. Further, as the number of bolts increases, the number of bolt mounting points increases accordingly, and it takes time and effort to mount the ridge on the frame. Further, in order to add transparency to the sound insulation plate, for example, when a transparent plate is used as the sound insulation thin plate, the larger the size of the frame and the ridge, the lower the ratio of the transparent part and the frame.・
The problem is that the ridge becomes obtrusive and makes it difficult to see.

Another object is to provide a sound insulation plate that can increase the opening ratio of the frame body and the ridge.

A plurality of protrusions are provided at one of the contacting portions that are in contact with each other at the attachment portion with the plurality of protrusions at intervals along the longitudinal direction of the contacting portion, and the frame body and the ridge are attached to each other.

On one side, a plurality of protrusions are provided at intervals along the longitudinal direction of the abutment part, and on the other side of the abutment part, the plurality of protrusions are attached with the frame body and the ridge. Since there are provided a plurality of recesses that are individually fitted, the frame body and the ridge (hereinafter, referred to as both members) are attached in a state in which the protrusion and the recess are fitted to each other at the contact portion. It is possible to make it possible to prevent the two members from moving in different directions along the contact surface on the contact surface by fitting the protrusion and the recess, and as a result,
When an external force acts on both members, it is possible to suppress the contradictory deformation of both members at the contact surface, and it is possible to reduce the amount of bending of both members. That is, it is possible to suppress the contradictory deformation of both members at the contact portion by fitting the protrusion and the recess together with a fixture such as a bolt for attaching both members. It is possible to reduce the bending of both members without increasing the cross section of the tool or increasing the number of installation locations. As a result, it is not necessary to increase the number of through holes of the attachment for both members, and it is not necessary to increase the cross section or increase the size of both members. Therefore, for example, even when a transparent plate is used as the thin plate, a wide transparent surface can be secured. In addition, since the position of the ridge with respect to the frame is automatically determined by fitting the protrusion and the recess, it is possible to easily position the ridge on the frame and to reduce the mounting labor.

ことを防止することが可能となる。The frame 3 is made of aluminum, and as shown in FIGS. 1 and 2, an upper frame 3A, a lower frame 3B, and a pair of hollow prisms each having a step on the inner side of the frame. The horizontal frame 3C of FIG. In addition to the frames 3A, 3B and 3C, the upper and lower frames 3A and 3B may be interposed between the horizontal frames 3C depending on the size of the sound insulating plate and design stress on the sound insulating plate.
There may be a middle frame that extends over the entire length. Each of the frames 3A, 3B, 3C is provided with a pressing fixing portion 5 for mounting the pushing edge 4 which is pressed and fixed along the surface direction of the sound insulating thin plate 2 arranged in the frame, and the A support portion 6 is provided between the ledge 4 and the sound insulating thin plate 2 so as to be able to sandwich it. The pressing / fixing portion 5 is provided with a plurality of recesses 5a into which a plurality of protrusions 4a provided on a mounting surface 4b of the pushing edge 4 described later can be individually fitted. The recesses 5a are spaced from each other along the longitudinal direction of the pressing and fixing portion 5, and are arranged in a plurality of rows along the thickness direction of the sound insulation thin plate 2. Further, at the upper end portion of the upper frame 3A and the lower end portion of the lower frame 3B, fitting portions 7 for vertically adjacent other sound insulating plates are provided, and the supporting portion 6 of the upper frame 3A is provided. Is provided with a plurality of screw members 6a which can be attached and fixed through the sound insulating thin plate 2 in the thickness direction in a detachable manner. Therefore, the sound insulating thin plate 2 has an upper edge portion fixedly attached to the upper frame 3A by the screw member 6a, and the other edge portions are pressed by the pushing edge 4 against the lower frame 3B and the horizontal frame 3C to be clamped. I support it. Therefore, when an impact force such as a wind or a collision of an automobile acts on the wall W, the sound insulating thin plate 2 is deformed by its elasticity, but in the peripheral portion of the sound insulating thin plate 2, a pair of horizontal frames 3C is formed. And, at the side supported by the lower frame 3B, the restraint is only to sandwich the sound insulation thin plate 2 from both sides, and not to penetrate the sound insulation thin plate 2, so that it slides out with respect to the ridge 4. It is possible to prevent the impact force from intensively acting on the sound insulation thin plate 2. Moreover, since the upper edge portion of the sound insulating thin plate 2 is fixed to the frame body 3 (specifically, the upper frame 3A) via the screw member 6a penetrating the sound insulating thin plate 2, a part of the sound insulating thin plate 2 is formed. Even if it is removed from the frame body 3, it can be strongly supported and can maintain a fixed state, and it is possible to prevent the sound insulating thin plate 2 from falling off from the frame body 3.
