Description

  The present invention relates to a partition wall body, and more particularly to a partition wall body that is assembled and configured using a lightweight thin panel such as an ALC panel and used as a building material.

Autoclaved Lightweight Aerated Concrete (ALC) is molded and used in lightweight thin panels in Japan. The ALC panel thus molded is lightweight and convenient for transportation and storage at the work site. Because of its excellent sound insulation, water resistance, fire resistance, and workability, it is widely used for the outer walls, roofs, floors, partition walls, etc. of general buildings and high-rise buildings.
In addition to ALC panels, various products such as gypsum board panels are manufactured and used as this type of lightweight thin panel. However, when used as a building material, its strength, especially in urban buildings. When used, heat resistance and sound insulation against fire are important characteristics.
Further, as a performance required as a non-bearing partition wall body that does not require structural strength, reduction of vibration transmitted from the neighbor to the partition wall is required due to the recent demand for comfort of living.
Furthermore, as for general partition wall bodies, its performance is mainly evaluated by fire resistance and sound insulation performance. The fire resistance satisfies the 1-hour fire resistance standard of non-bearing partition walls by the Building Standard Act, and the sound insulation performance is also the same as the building standard. It is required to satisfy the sound insulation class D-40 or more, more generally D-45 or more, according to the regulation of the sound insulation structure of the boundary wall by law.

As such a partition wall body using an ALC panel, as shown in FIG. 4, the upper end of the ALC panel 17 is fixed to one runner 21 arranged on the beam slab 24, and the lower end of the ALC panel 17 is further fixed. The ALC panel 17 is fixed to the floor slab 25 with a dedicated metal fitting 23, and a plurality of ALC panels 17 are arranged in a staggered manner in the length direction of the runner 21 between the beam slab 24 and the floor slab 25. The fiber material 12 is filled and arranged in contact with the surface in a plate shape, and generally a fireproof board 18 such as a gypsum board is grounded so as to sandwich the outer surface of the ALC panel 17 and the fiber material 12. There has been proposed a structure in which a fireproof board 19 is placed on top of each other (see, for example, Patent Document 1).
JP-A-8-93094

However, as a problem of the prior art, it has a structure in which all the components are connected to one runner at the top, and the structure that makes the front and back members of the wall contact each other at the runner portion, and transmits vibration. There was a problem.
In addition, since the wall thickness after finishing is determined by the runner width, when the wall thickness is increased and the air layer is increased to obtain high sound insulation performance, the runner is increased in size and is not economical. In addition, when the runner is enlarged and the wall thickness after finishing is increased, a dedicated spacer is used in order to securely fix the structural member to the wide runner width, or the thickness of the ALC panel is increased. Countermeasures such as increasing it were necessary, and the materials used increased, which was not economical.
The present invention has been proposed in view of the above-mentioned conventional problems, and its purpose is to reduce vibration transmitted from the adjacent door through the partition wall body, and to change the thickness of the partition wall without any change in cost. It can be done easily, and also satisfies the 1-hour fire resistance standard of non-bearing partition walls according to the Building Standards Act, and satisfies the sound insulation class D-45 or higher, and has high performance with good workability compared to the conventional technology. The object is to provide an economical partition wall.

In order to solve the above-mentioned problems, the present invention is arranged such that panels and studs are alternately arranged in the length direction of a set of runners arranged in parallel vertically, and a fibrous material is placed in the space between the panels and studs. The wall body which is formed by pasting the board material on one side of the inner member made of the panel, the stud and the fiber material is filled, and the surface on which each board material is pasted is set outside. The partition wall body is configured to be arranged in parallel and filled with a fibrous material in the space between the two wall bodies.
By configuring the partition wall body in this way, each of the two sets of wall bodies constituting the partition wall body is arranged as a single wall, and since there is no rigid body portion that contacts each other, it occurs on one side of the partition wall body. The vibration is not transmitted to the other side. In addition, since each set of two bodies is a single wall, the thickness of the partition wall can be arbitrarily set without changing the size of the runner to be used. The thickness of the layer can be set, and construction according to the desired sound insulation performance can be easily performed, which is economical. Furthermore, by arranging the panels and studs alternately, it is possible to satisfy the required strength as a wall body despite the provision of a space between the panels and studs, and to construct with the minimum necessary materials. It is economical because it can.
Furthermore, since the nonflammable fibrous material is filled in the gap inside the partition wall body, fire resistance and sound insulation performance can be improved.

In the partition wall of the present invention, it is preferable that the panels and studs of the two bodies in one set are arranged in a staggered pattern of opposite phases at equal intervals in the runner length direction.
By configuring the partition wall body in this way, there is no weak point of fire resistance performance and sound insulation performance of the partition wall body, and stable performance can be exhibited over the entire surface.

In the partition wall body of the present invention, it is preferable that the panel, the board material, and the fibrous material are all incombustible materials.
Moreover, an autoclave foam concrete panel can be used as the said panel.
Also, the board material it is preferred to use a surface density of ^{8kg / m 2 ~25kg / m 2} .
By using such materials, the necessary strength is ensured, the 1-hour fire resistance standard of the non-proof partition walls according to the Building Standards Act is satisfied, and the sound insulation class D-45 or higher is satisfied. Thus, it is possible to obtain a high-performance and economical partition wall body with good workability.

According to the present invention, each set of two walls constituting the partition wall body is arranged as a single wall, and there is no contact portion. Therefore, vibration generated on one side of the partition wall body is the other side. It is not transmitted to. In addition, since each pair of walls is a single wall, the wall thickness can be set arbitrarily without changing the size of the runner used, etc., so the thickness of the air layer can be increased without increasing costs. Can be set, and construction according to the desired sound insulation performance can be easily performed, which is economical.
Furthermore, it is economical because a space can be provided by alternately arranging the panels and studs, and the construction can be made with the minimum necessary materials that can satisfy the required strength as the wall. Furthermore, since the nonflammable fibrous material is filled in the gap inside the partition wall body, fire resistance and sound insulation performance can be improved.
In particular, since the panels and studs inside the partition wall composed of a set of two bodies are arranged in a staggered pattern of opposite phases at equal intervals alternately in the runner length direction, Since the panels and studs are uniformly arranged in the length direction, there is no weak point of fire resistance and sound insulation performance of the partition wall body, and stable performance can be exhibited over the entire surface.
In the present invention, since nonflammable materials are used as the panel, board material, and fibrous material, the one-hour fire resistance standard of the non-proof partition walls according to the Building Standards Act can be satisfied.
Moreover, if an ALC panel is used as the panel, a high-performance and economical partition wall body that is lightweight and has good workability can be provided.

The present invention will be described in detail with reference to FIGS.
FIG. 1 is a perspective sectional view showing the configuration of a wall body used in the invention, FIG. 2 is a perspective sectional view of a partition wall body showing the final configuration of the present invention, and FIG. 3 is a horizontal sectional view of the partition wall body of FIG. .

As shown in FIG. 1, the wall body 9 used in the present invention is provided with a pair of upper and lower runners 21 on the upper surface of the floor slab 15 and the lower surface of the upper beam slab (not shown). Panels 1 and studs 11 are alternately fixed to the runner 21 at regular intervals along the length direction.
A space between the panel 1 and the stud 11 is filled with a fibrous material 12. And the base board material 14 is stuck and fixed to one side of the base composed of the panel 1 and the stud 11 by a fixing member such as a screw 8.

As the panel 1, for example, a rectangular plate-shaped ALC panel made of a heat resistant material is selected. Or it is also possible to use a wood chip cement board, a gypsum board, a calcium silicate board, and a board containing glass fiber, carbon fiber or asbestos fiber. The panel 1 is supported by being fitted into the grooves of the upper and lower runners 21. At this time, the width of the runner 21 is set to be equal to or wider than the thickness of the panel 1. When the width of the runner 21 is wider than the thickness of the panel 1, the panel 1 is fitted and fixed through a spacer or the like as appropriate.
As the stud 11, a strong one made of lightweight steel or the like is used. For example, it is preferable that the cross-sectional shape is a square, an H-shape, a U-shape, or an inner bent portion formed at the end of the U-shape. Since the size is accommodated in the runner 21, the width of the runner 21 is not exceeded. The stud 11 is fitted and fixed to the upper and lower runners 21. At this time, the width of the runner 21 is set to be equal to or wider than the size of the stud 11. When the width of the runner 21 is wider than the size of the stud 11, the stud 11 is fitted and fixed through a spacer or the like as appropriate.
As the fibrous material 12, a heat-resistant non-combustible fibrous material such as glass wool or rock wool is used. The fibrous material 12 is constructed by forming these non-combustible fibrous materials into a mat shape and inserting them into the space between the panel 1 and the stud 11. In this way, when two wall bodies 9 described later are arranged in parallel, the space between the planes of the panel 1 and the stud 11 can be filled, which is convenient.
Further, the board material 14 may be made of a heat-resistant material such as a cement board, a gypsum board, a calcium silicate board, or a fiber-incombustible board material such as glass fiber or carbon fiber. Further, the surface density of the board material 14 is desirably 8 kg / m ² to 25 kg / m ² . This is because if the surface density is less than 8 kg / m ² , the sound insulation grade D-45 or higher cannot be secured due to a decrease in the sound insulation performance, and if it is greater than 25 kg / m ² , the construction performance may deteriorate due to heavy construction. .
The board member 14 is fastened and fixed to the panel 1 and the stud 11 using the screws 8.

Two wall bodies 9 each having a board material fixed on one side are set as one set, and the surfaces on which the respective board materials are fixed are arranged in parallel with each other on the outside.
The two wall bodies 9 in combination are arranged so that the panels 1 and the studs 11 of the two wall bodies 9 are alternately staggered at equal intervals in the runner length direction. It is preferable to do this. The partition wall body 10 is configured by arranging the distance between the two wall bodies 9 so as to satisfy a desired wall thickness. Since the nonflammable fibrous material 12 such as glass wool or rock wool comes into contact with the space between the panel of one wall body of the partition wall body 10 and the board material of the other wall body as described above, the fibrous material 12 will be filled.
By adjusting the installation width of the two runners, it is possible to arbitrarily adjust the interval between the panels 1 of the two wall bodies 9, but the board material of one wall body and the other wall body It is effective to adjust the thickness of the fibrous material 12 so as to fill the gaps between them in order to enhance the sound insulation effect.

The partition wall body 10 configured as described above does not have a portion where the rigid bodies on one side and the opposite side directly contact each other, and is physically insulated. The generated vibration is not transmitted to the opposite side.
Furthermore, since the partition wall body 10 has a structure composed of two bodies and one set of wall bodies, it is possible to change the mounting interval between the runners for the partition wall bodies arranged above and below without changing the materials to be used. The partition wall thickness can be easily set.
Furthermore, since the fibrous material is filled in the gap inside the partition wall body, it is possible to improve heat resistance and sound insulation performance by suppressing transmission of heat and sound waves.
Further, the combined two-body wall body 9 is so that the panels 1 and the studs 11 of the two wall bodies 9 are alternately staggered at equal intervals in the runner length direction. Since the panels and studs are arranged at equal intervals and a space is provided between them, the partition wall body can be configured with the minimum amount of material to obtain the desired strength, which is economical. is there.

Moreover, since the panel 1 and the stud 11 are uniformly arranged in the length direction of the partition wall body 10, there is no weak point of fire resistance performance and sound insulation performance of the partition wall body, and the stable performance is exhibited over the entire surface. Can do.
Furthermore, by selecting an ALC panel which is a fireproof and soundproof material for the panel 1, it is possible to have a one hour fireproof performance of the non-proof partition wall and further improve the soundproof performance.

  With the above configuration, the partition wall body according to the present invention can reduce vibration transmitted from the adjacent door via the partition wall body, and can easily change the wall thickness without changing the cost. The non-proof partition wall according to the Building Standard Law satisfies the 1-hour fire resistance standard, satisfies the sound insulation class D-45 or more, and has a high performance and economical partition wall body with better workability compared with the prior art.
