Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a soundproof panel connecting structure used for connecting soundproof panels in, for example, a soundproof room, a soundproof capsule, a wall or ceiling of a house, or a partition.

[0002]

[Prior art]

 In a conventional soundproof panel connection structure, generally, the soundproof panels are connected to each other via connecting fittings with the side surfaces of the two soundproof panels butted against each other. In this case, there is a type in which the side surface of each soundproof panel, that is, the connecting surface is formed into a tongue-and-groove shape or an interlocking shape, or a female groove is provided on the connecting surface to connect the soundproof panels through a hilt. This makes it easy to align the soundproof panels with each other, and even if there is a gap between the connecting surfaces due to variations in the manufacturing and construction of the soundproof panel, the noise that passes through the gap will be reduced. By lengthening the transmission path and bending it, the soundproof performance is kept as low as possible.

[0003]

[Problems to be solved by the device]

 However, in these conventional soundproof panel connection structures, it is assumed that some gaps will occur between the soundproof panel connection surfaces due to variations in manufacturing and construction, and the sound transmission path that passes through these gaps. There is a limit to the soundproofing performance that can be obtained because it is simply lengthened or bent.

Of course, if the gap is not formed between the connecting surfaces, the above-mentioned problem is solved, but for that purpose, it is necessary to process and install the soundproof panel with high accuracy. In that case, it takes a considerable amount of time and labor to process and install the soundproof panel.

The present invention has been made to solve such a problem, and can reliably and easily improve the soundproof performance without requiring high processing accuracy and construction accuracy. It is intended to provide a connection structure for soundproof panels.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a soundproof panel connecting structure for connecting two soundproof panels in a state where the side surfaces of the soundproof panels are butted against each other. Equipped with female ridges extending continuously from the upper surface to the lower surface of the soundproof panel, both female ridges are continuous with each other when the side surfaces of the two soundproof panels are butted, and are narrowed and inclined from one to the other. It further has a taper surface, fitted in one of the female ridges in a retaining state, movable in the connecting direction, and pressing means for pressing the female ridge against the tapered surface of the female ridge. It is characterized by that.

In this case, it is preferable that an elastic seal member is provided on the tapered surface.

[0008]

[Action]

 According to this soundproof panel connection structure, in order to connect the two soundproof panels, first, one of the female tabs provided on each side of the soundproof panel is provided with the movable tab movable in the connecting direction. By mating and abutting both sides, the female toes are connected to each other. As a result, a continuous tapered surface that slopes from one to the other is formed on both female ridges. At this time, the worker is pressed against the tapered surface by the pressing means. In this state, the two soundproof panels are connected. In this case, the worker's tongue comes into contact with the tapered surfaces of the female tongues while being pressed by the pressing means, so that the gap between the connecting surfaces can be closed. Therefore, the sound passing between the connecting surfaces can be reliably and greatly attenuated.

According to the soundproof panel connection structure of the second aspect, since the elastic seal member is provided on the tapered surface of the series of female ridges, the worker's ridge penetrates into the elastic seal member by the pressing means. It is pressed in the state. This makes it possible to more reliably close the gap between the connecting surfaces while absorbing variations in processing and construction of the soundproof panel. Therefore, the sound passing between the connecting surfaces can be more surely attenuated.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an upper perspective view showing a soundproof panel connection structure according to the present embodiment. FIG. 2 is a horizontal sectional view thereof. As shown in FIG. 1 and FIG. 2, this connecting structure 1 connects two soundproof panels P1 and P2 in a state of being abutted against each other, and is provided on each side surface of the two soundproof panels P1 and P2, that is, a connecting surface. Female ridge 2, a cushion rubber (elastic seal member) 3 provided on the female ridge 2, a stud 4 fitted to the female ridge 2, and a spring (pressing the female ridge 4 against the female ridge 2). Means) 5 and.

Although not shown here, each of the two soundproof panels P1 and P2 encloses glass wool inside a frame formed by lauan plywood, and the front and back surfaces of the frame include gypsum board and particle board. It is configured by attaching panels such as, and is formed in a vertically long rectangular shape.

The female tongue 2 includes a left female tongue 6 (when viewed from the direction of arrow A in FIG. 1) provided on the left side of the right soundproof panel P1 and a right provided on the right side of the left soundproof panel P2. It consists of a female shank 7. The left and right female ridges 6 and 7 continuously extend in the vertical direction from the upper surface to the lower surface of the soundproof panels P1 and P2, respectively.

The left female tongue 6 has a trapezoidal horizontal cross section that widens toward the center from the left side surface of the soundproof panel P1. The right female tongue 7 has a trapezoidal horizontal cross section that narrows from the right side surface of the soundproof panel P2 toward the center side.

The opening width of the right female tongue 7 opened on the side surface side of the soundproof panel P2 is the same as the opening width of the left female tongue 6, and therefore the side surfaces of the two soundproof panels P1 and P2 are butted against each other. At this time, the left female tongue 6 and the right female tongue 7 are abutted against each other, thereby forming a substantially series of female tongues 2 having a tapered horizontal cross section. The cushion rubber 3 is provided on the tapered wall surface, that is, the tapered surface (tapered surface) 8.

The cushion rubber 3 is made of synthetic rubber such as neoprene rubber and is formed in a sheet shape. The cushion rubber 3 is attached to the entire tapered surfaces 8 of the left and right female ridges 6 and 7, respectively.

The hiring pad 4 is made of lauan plywood, MDF or the like, has a shape complementary to the female tab 2, has the same taper angle as that of the female tab 2, and more It is formed small around. A plurality of recesses (not shown) for receiving the springs 5 are formed on the right wall surface of the hire 4 at predetermined intervals in the vertical direction. A spring 5, which is a coil spring, is fixed to the recess with one end thereof inserted, and the other end of the spring 5 is brought into contact with the back surface of the left female tongue 6.

Here, a method of connecting the two soundproof panels P1 and P2 and a soundproof operation of the soundproof panels connected to each other will be described. The connection method will be described assuming that the left soundproof panel P2 is already fixed and the right soundproof panel P1 is connected thereto.

First, the connecting method will be described. Tilt the soundproof panel P1 on the right sideways with its left side facing upwards, and gradually push in the hiring pad 4 from one end of the left female tab 6 with the spring 5 compressed. To insert. The fully inserted labor tongue 4 is brought into surface-contact with the cushion rubber 3 on the tapered surface 8 of the left female tongue 6 by the spring force of the spring 5, and the left portion of the labor tongue 4 is attached to the soundproof panel 1. It projects from the side. In this state, the soundproof panel P1 is raised, the left side of the soundproof panel P1 is abutted against the right side of the fixed left soundproof panel P2, and pressed against the left side of the hire 4 to bring the left side of the soundproof panel P2 into contact with the right female shank. Insert in 7. As a result, the hiring pad 4 is forcibly pressed against the cushion rubber 3 on the tapered surfaces 8 of the left and right female tabs 6, 7 in a surface contact state. Therefore, the gap between the connecting surfaces is completely closed by the hilt 4. In this state, the connecting metal fitting is made to straddle between the two soundproof panels P1 and P2 and fixed by screws (neither is shown). As a result, the work of connecting the soundproof panels P1 and P2 is completed.

Next, the soundproofing operation will be described. First, the sound that has entered through the gap between the connecting surfaces goes straight, hits the wall surface of the higaku 4, diffracts, and at the same time branches into two, and is attenuated to some extent at this stage. Next, each branched sound travels along the wall of the hire 4. In this case, since the worker's tongue 4 is pressed against the tapered surface 8 of the female tongue 2 in a surface contact state without a gap, when passing through the wall surface of the worker's tongue 4, the sound is greatly attenuated. In addition, since the hiring pad 4 is pressed against the cushion rubber 3, if there are variations in the processing and construction of the soundproof panel, these variations are absorbed and the hiring tab is hired. The gap in the wall surface of No. 4 is continuously and reliably closed. Therefore, the soundproof performance of the soundproof panel connecting structure 1 can be reliably and easily improved. The sound that has passed through here is further diffracted, and is further attenuated step by step.

Although the spring is used as the pressing means in the embodiment, a long bolt may be used instead of the spring. In this case, make a through hole between the side surfaces of the soundproof panel, pass the long bolt through this, attach one end of the long bolt to the ridge, and press the ridge against the tapered surface while the other end of the long bolt is pressed. Part should be fixed to the side of the soundproof panel. Also, although the spring is fixed to the hilt side, it may be fixed to the soundproof panel side, that is, the back of the female tongue. In addition, the detailed configuration can be appropriately changed without departing from the spirit of the present invention.
