Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a partition wall structure.

(Problems to be solved by the prior art and the invention) Conventionally, as a barrier wall structure, there is a hollow wall structure that is lightweight and the wall thickness can be freely set, but since the wall plates on both sides are thin, the bending of the wall plate itself Sound is easily transmitted by vibration. For this reason, a plurality of metal studs are erected on the runner provided on the ceiling surface and the runner provided on the floor corresponding to this, and the wall plate is erected via this stud. However, since both ends of the stud are fixed to the runners provided on the ceiling surface or floor surface, solid vibration is easily transmitted, and desired sound insulation cannot be obtained.

On the other hand, in order to reduce the propagation of sound due to solid vibration, there is a connector in which upper and lower ends are not fixed to the runner and are arranged between adjacent wall plates. For example, the partition structure described in Japanese Examined Patent Publication No. 1-333618.

However, in this partition structure, a joiner having a substantially H-shaped cross-section is arranged between adjacent wall plates, and the side ends of the adjacent wall plates are simply fitted into the opposing groove portions of the joiner. Rattle and gaps are likely to occur on the wall plate due to pressure and sound pressure from not being able to obtain sufficient sound insulation characteristics,
When the construction is sequentially performed, it is difficult to fit the side end of the tensioned wall plate into the groove of the joiner, so that there is a problem that the construction on site is not easy.

The present invention has been made in view of the above problems, and an object thereof is to provide a partition wall structure which is excellent in sound insulation and can be easily installed on site.

(Means for Solving the Problems) In order to achieve the above object, the partition wall structure according to the present invention has a ceiling rail provided on the ceiling, and a floor rail provided on the floor so as to face the ceiling rail. A connector arranged between adjacent wall plates, a wall plate erected so as to face each other with the ceiling rail and the floor rail in between, and a space formed between the wall plates facing each other are filled. In a partition wall structure made of a sound absorbing material, the connecting member is a main body made of a long mold member having a substantially U-shaped cross section or a substantially R-shaped cross section,
The main body includes an engaging claw portion having a substantially L-shaped cross section, which is provided at a substantially central portion along the lengthwise direction of the outer surface of the main body, and allows the upper and lower ends of the connector to contact the ceiling rail and the floor rail. Of the adjacent side ends of the adjacent wall plates, the side end of one wall plate is fitted to the engaging claw portion, and the side end of the other wall plate is attached to the outer surface of the remaining main body. Is abutted against and screwed.

(Operation) Therefore, according to the present invention, one side end portion of the wall plate is provided without contacting the connecting tool for supporting both end portions of the wall plate forming the wall surface of the partition wall with the ceiling rail and the floor rail. The side end of the other wall plate is screwed to be integrated with the outer surface of the remaining main body while being fitted into the engaging claw of the connector.

(Embodiment) An embodiment according to the present invention will be described below with reference to the accompanying drawings of FIGS. 1 to 10.

The partition wall structure according to the present embodiment generally includes a ceiling rail 2 provided on a ceiling 1, a floor rail 4 provided on a floor 3 so as to face the ceiling rail 2, and a space between the ceiling rail 2 and the floor rail 4. A wall rail 6 provided on the wall 5 so as to be located at, a fire prevention wall plate 7 standing upright so as to face each other with the rails 2, 4, 6 interposed therebetween, and an adjacent fire prevention wall plate.
From a connector 8 arranged between 7, 7; a glass wool 13 filled in a space 12 formed between the opposing wall plates 7, 7; and a surface plate 14 covering the outer surface of the wall plate 7. It will be.

The rails 2, 4, 6 are made of a mold material having a substantially U-shaped cross section and having the same cross section, and are fixed to the ceiling 1, the floor 3, and the wall 5 with screws, respectively.

Examples of the fire protection wall plate 7 include those made of an inorganic fiber reinforced gypsum board, a calcareous plate, a slag gypsum plate, and a wood chip cement plate. Thus, the wall surface is formed.

As shown in FIG. 4, the connecting member 8 is made of a material in which a substantially L-shaped engaging claw portion 10 is projectingly provided on an outer surface 9a of a main body portion 9 having a substantially U-shaped cross section.

The connector 8 is not limited to the one in the above-described embodiment, but may be the fifth one.
As shown in the figure, a substantially L-shaped discontinuity is formed on the cylindrical main body 9 having a substantially rectangular shape.
The engaging claw portion 10 having a U shape may be integrated, and as shown in FIG. 6, the engaging claw portion 10 having a substantially L shape may be integrated with the body portion 9 having a substantially U shape. The cushion material 11 may be integrated with the base of the engaging claw portion 10.

Next, in order to construct the partition wall structure according to the present embodiment, first, the rails 2, 4, 6 are screwed to the ceiling 1, floor 3 and wall 5, respectively, and then the rails 2, 4 are placed above and below the wall plate. The end portion is screwed and the side end portion of the wall plate 7 is screwed to the rail 6 provided on the wall 5 to stand upright. Then, the engaging claw portion 10 of the connector 8 is press-fitted and fitted to the side end portion of the wall plate 7. The connecting tool 8 may be fitted to one side end of the wall plate 7 in advance and then attached to the rails 2 and 4. At this time, the connector 8
The upper and lower ends do not touch either of the rails 2 and 4.
Further, the side end portions of the other wall plates 7 are positioned on the base portion of the engaging claw portion 10 and screwed to the outer surface 9a of the main body portion 9, and the upper and lower end portions thereof are screwed to the rails 2 and 4. After that, the same operation is repeated, and when the wall 5 is to be stretched as shown in FIG. 2, the wall plate 7a cut into a predetermined width is screwed at both ends to form a wall surface on one side of the partition wall. To do.

Then, after the glass wool 13 is placed on the wall surface on one side of the formed partition wall and temporarily fixed, the same operation as described above is repeated to form the remaining wall surface on one side.
At this time, the connecting members 8 are arranged in a zigzag pattern with respect to the other connecting members 8 facing each other.

Finally, the work of assembling the partition wall is completed by fastening the surface plate 14 made of a slag gypsum plate, a calcareous plate or the like to the surface of the fire protection wall plate 7.

Experimental example At a construction site, the width shown in Figs. 1 to 3
An experimental partition wall of 4000 mm, height 2700 mm, and wall thickness 129 mm was formed.

The rails 2, 4, and 6 of the partition wall have a width of 77 mm, a height of 40 mm, and a wall thickness.
It consists of zinc iron plate mold material of 0.6 mm or more, the fire prevention wall plate 7 has a thickness of 21 mm inorganic fiber reinforced gypsum board, and the connector 8 has the shape shown in FIG. 4, the maximum width is 75 mm, the maximum height is 45 mm, Wall thickness 0.6m
The glass wool 13 is made of zinc-iron plate material of m or more, and the partition wall has a width of 75 mm.
The surface plate 14 is made of a slag gypsum plate having a thickness of 6 mm, which conforms to JIS-A-6306 at mm or more and 24 kg / m ² or more.

On the other hand, the partition wall according to the comparative example is different from the partition wall according to the present invention described above in the shape of the connector 8 and the mounting structure of the wall plate 7.

That is, as shown in FIG. 7, the shape of the connecting member 8 is such that a substantially T-shaped engaging claw portion 15 is projectingly provided on the back surface of the substantially U-shaped main body portion 9, and the wall plate 7 is attached. As shown in FIG. 8, the structure is such that both side ends of the wall plate 7 adjacent to each other are fitted in the groove formed by the engaging claw portion 15 of the connecting tool 8.

Since the rail material, the wall plate and the like are the same as the partition wall according to the present invention described above, the description thereof will be omitted.

A load was applied to the respective central portions of the partition wall of the present invention and the partition wall of the comparative example having the above-mentioned structure, and the displacement in the wall thickness direction was measured. The measurement results are shown in FIG.

As is clear from the measurement results shown in FIG. 9, it was found that the partition wall structure according to the present invention has a smaller displacement amount. From this result, it is considered that since the partition wall structure according to the present invention has higher rigidity, solid vibration is reduced.

Next, the spatial average sound pressure level difference was measured based on the measuring method (JIS-A-1417) of the sound pressure level difference at the building site. The measurement results are shown in FIG.

As is clear from the measurement results shown in Fig. 10, the frequency
Both the present invention and the comparative example have almost the same sound insulation characteristics up to 1kHz, but when the frequency becomes 1kHz or more, the sound insulation characteristic of the comparative example drops sharply, whereas the sound insulation of the partition wall according to the present invention The characteristics are not deteriorated as in the comparative example. Therefore, according to the partition wall structure of the present invention,
In the mid-to-high range (more than the coincidence limit frequency) where the sound insulation performance is said to be lower than the mass law value due to resonance, that is, even if the frequency is 1 kHz or more, the transmission loss is greatly improved. It was found that excellent sound insulation characteristics can be maintained.

As described above, the partition wall according to the present invention has excellent sound insulation characteristics because the upper and lower ends of the connector are not in contact with the ceiling rail and the floor rail, but both sides of the wall plate are different from each other as in the comparative example. It is considered that rigidity is increased against sound pressure by fixing one end of the wall plate to the main body of the connector with screws instead of simply fitting the end to the connector.

(Effect of the Invention) As is apparent from the above description, according to the present invention, the connector is attached without contacting the ceiling rail and the floor rail. Since one end portion is screwed to the connecting tool, the rigidity of the partition wall, particularly the wall plate as a whole, is increased to make it difficult for the wall plate to vibrate, and solid vibration is reduced to improve sound insulation characteristics.

In addition, the connecting portion has a main body having a substantially U-shaped cross section or a substantially rectangular cross section, and the second moment of area is large, so that the rigidity of the connecting tool is large. For this reason, the wall plate is less likely to bend in the plate thickness direction and solid vibration is reduced, so that desired sound insulation characteristics can be obtained.

Further, according to the invention of the present application, the engaging claw portion of the connector is fitted to one end portion of the wall plates that are sequentially erected, and one end portion of the other wall plate is positioned and screwed to the outer surface of the remaining main body portion. Since it is stopped, there is no rattling or gap due to external pressure, and the sound insulation characteristics are further improved.

Further, in the tensioning operation, the side end portion of the wall plate cut to a predetermined width can be screwed to the outer surface of the connector from the front, and the wall plate can be easily assembled, which facilitates on-site construction. In particular, since adjacent wall plates can be connected by one connecting tool, there is an effect that the number of parts and the number of assembling steps are small, and a partition wall structure having high productivity in field construction can be obtained.
