Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention can be applied to a unit building such as an apartment house or a rental office building, which has a plurality of living room divisions occupied by different users on the same floor.

2. Description of the Related Art Conventionally, in a building such as an apartment house, in order to protect the privacy and the like of each house, a room wall partitions the indoor space for each house. The boundary wall generally has a hollow structure in which a sound insulating material is filled between a pair of wall materials.

In such a boundary wall, a plurality of vertical rails are arranged on the back surface of the wall material, and the wall material is attached to the vertical rails in each row to support the wall material. There is also a staggered arrangement type in which the arrangement of these vertical bars is staggered. In such a staggered array wall, the vertical rails of each wall material are arranged between two vertical rails of each other. As a result, the vertical bars of the wall members do not come into contact with each other even when pressed, and vibrate separately. Therefore, even if sound is generated in one space of the field wall and the wall material on the space side vibrates, the wall material on the opposite side does not vibrate. Therefore, the sound volume transmitted from one of the wall materials to the other is reduced, and the sound insulation efficiency can be improved. In addition, even if the vertical bars of each wall material are large, the intervals of the vertical bars arranged in a staggered pattern are about half, so a grid with a fine pitch is formed inside the boundary wall. By making the product, it is possible to prevent the intrusion of others and it becomes a safe barrier for security.

[0004]

However, since the boundary wall of the staggered array type is premised on that the assembly is carried out at the construction site, if the boundary wall is to be provided in the unit building,
Assembly of the boundary wall and interior decoration around the boundary wall are done on site. For this reason, the work at the construction site is greatly increased by installing the boundary wall, and there is a problem that the merit of the unit building that the construction period is extended and construction can be performed in a short period of time is impaired. Due to this problem, it is not possible to introduce staggered boundary walls into unit buildings, despite many requests.

An object of the present invention is to provide a method of assembling a boundary wall of a unit building in which work on a construction site is reduced.

[0006]

SUMMARY OF THE INVENTION The present invention is a method for assembling a boundary wall of a unit building for assembling a boundary wall installed at a joint portion of two joined building units, wherein the first building unit is joined in advance. A wall material having a plurality of vertical bars along the edge is installed so that its back side is the outer side to form a first boundary wall portion, and a plurality of wall materials are provided along the joining edge of the second building unit. The wall member having the vertical bar is installed so that its back side is the outer side, and the vertical bar is arranged so as to be displaced from the vertical bar of the first wall part to form the second wall part. It is characterized in that it is formed, and the first and second building units are joined to each other in a state where a sound insulating material is interposed between the first and second field wall portions.

[0007]

In the present invention as described above, since the first and second boundary walls which are the wall surfaces on the indoor side are formed in advance in the first and second building units, the first and second building units are formed. By the mutual joining of, the staggered type boundary wall is automatically formed, and the site work is greatly reduced. Further, since it is possible to complete the interior of the first and second boundary walls around the factory, it is necessary to perform the interior of the first and second boundary walls around the construction site. And the above-mentioned objects are achieved by them.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows first and second building units 1 and 2 of the present embodiment, and these building units 1 and 2 are of a so-called box type and have side surfaces facing each other. It is supposed to be joined.

Each of the building units 1 and 2 has a frame 5 in which upper and lower ends of columns 3 arranged at four corners are connected by beams 4, respectively. On the underside of the beam 4 above the frame 5,
A ceiling material 6 is attached and a floor material 7 is attached to the upper side of the lower beam 4. Building unit 1,
At the boundary part of 2, the first and second boundary wall boundaries are respectively provided.
A boundary wall 8 including 10, 20 and a sound insulating material 30 is provided.

2 and 3, the first and second field wall fields 10, 20 are shown enlarged. In the figure,
The ceiling material 6 and the floor material 7 of the first building unit 1 are provided with runners 11A and 11B along the edges. Runner 11
A and 11B are long members having a U-shaped cross section, and are installed with their openings facing each other. A plurality of vertical bars 12 are linearly arranged between the upper and lower runners 11A and 11B. A wall material 13 such as a gypsum board having a thickness t is attached to the left side of these vertical bars 12 in the figure, and a series of these runners 11A, 1A, 1
The first boundary wall portion 10 is formed by 1B, the vertical crosspiece 12, the wall material 13, and the like.

On the side of the building unit 2 of the first boundary wall 10,
The sound insulating material 30 is attached with nails or the like. The sound insulating material 30 is obtained by unwinding glass wool rolled into a roll and cutting it into a predetermined size.

Like the first building unit 1, the ceiling material 6 and the floor material 7 of the second building unit 2 are provided with runners 21A and 21B along the edges thereof. Runner 21A, 21B
Like the runners 11A and 11B, is also a long member having a U-shaped cross section, and the openings are arranged so as to face each other. A plurality of vertical bars 22 are linearly arranged between the runners 21A and 21B. Inside the vertical bars 22, a wall material 23 such as a gypsum board similar to the wall material 13 is attached, and the second boundary wall portion 20 is formed.
Are formed.

Here, the vertical bar 22 of the second boundary wall portion 20 is the first
The vertical wall 12 of the boundary wall portion 10 of the building is arranged at a position displaced from each other, so that when the building units 1 and 2 are joined to each other,
12,22 form a staggered array.

The thickness t of the wall materials 13 and 23 is about 12
mm is enough. When fire resistance is required,
By setting it to 15 mm or more, the boundary wall 8 becomes a fire resistant wall and has a fire resistant performance that passes the certification of fire resistance for 1 hour.

In this embodiment, when the building units 1 and 2 are manufactured in advance in a factory or the like, each building unit 1,
Boundary wall parts 10 and 20 are formed in 2 respectively, and interiors of the building units 1 and 2 are completed. Then, a sound insulating material 30 is attached to the back surface of the field wall portion 10 of the building unit 1 of the building units 1 and 2. Next, the building units 1 and 2 are carried to a building site, the building units 1 and 2 are joined to each other at the building site, and the back surfaces of the building wall portions 10 and 20 are opposed to each other to form a building wall 8.

According to this embodiment, the following effects can be obtained. That is, since the boundary walls 10 and 20 are formed in the building units 1 and 2 in a factory or the like in advance, the interior around the boundary walls 10 and 20 can be completed in the factory or the like.
Therefore, the interior work at the construction site can be almost omitted, and the boundary wall 8 is automatically formed by the mutual joining of the building units 1 and 2, and the site work can be greatly reduced. Therefore, even if the boundary wall 8 is provided, the unit building can be constructed in a short period of time and the staggered array type boundary wall can be introduced into the unit building.

Also, since the staggered boundary walls can be formed in the unit building, the sound insulation performance is improved, and even in the unit building, the privacy of each house can be sufficiently protected, and construction can be performed in a short period of time. You can improve the quality of the unit building.

Furthermore, since all the work can be performed on the back side of the boundary walls 10 and 20, no traces of nails are left on the surface of the boundary wall 8 and a beautiful surface finish can be obtained. Further, it is not necessary to hide the nail after the work and the interior work can be facilitated, and the time required for the interior work in the factory can be shortened.

Further, the thickness t of the wall materials 13 and 23 is set to 15 mm.
By making the above settings, the boundary wall 8 is designed to be a fire resistant wall that passes the 1-hour fire resistance certification. Therefore, the boundary wall 8 must have fire resistance performance, such as a building unit for high-rise buildings. Even in such a case, the wall materials 13 and 23 can be easily dealt with only by making them thick.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but includes the following modifications and the like. That is, in the above embodiment, the first boundary wall portion 10
The sound insulation material 30 was attached to the
May be attached, and the sound insulating material 30 may be attached to either or both of the first and second boundary walls 10 and 20. Here, the fixing of the sound insulating material 30 is not limited to being attached to the wall material, and for example, both sides of the suspended sound insulating material 30 may be sandwiched and fixed between the first and second building units, respectively.

Further, the runner is not limited to the one having a U-shaped cross section, but may be, for example, one having an L-shaped cross section, and the runner may have any shape suitable for mounting the vertical rail. The runner may be omitted when the vertical rail is directly attached to the floor and ceiling materials by using a jig or the like.

Further, the sound insulating material is not limited to the one made of glass wool, but may be rock wool packed in a bag, that is, any material capable of effectively blocking the sound trying to pass through the boundary wall.

The wall material for the boundary wall is not limited to gypsum board, but may be, for example, a panel made of lightweight aerated concrete. Anything will do.

[0024]

As described above, according to the present invention, since the boundary wall is automatically formed by joining the building units, the work at the construction site can be reduced.
