Description

Description: TECHNICAL FIELD The present invention relates to a sound insulation structure in an industrialized house constructed by combining a plurality of housing units, and particularly to a sound insulation structure at a connecting portion between housing units.

[Background technology]

Industrialized homes are built by combining a plurality of prefabricated home units in a factory at a construction site.
As shown in FIG. 4, the frame 11 of the housing unit 10 is
The four columns 12 at the four corners are connected by a short-side floor beam 13, a long-side floor beam 14, a short-side ceiling beam 15, and a long-side ceiling beam 16 to form a rectangular parallelepiped shape.

After attaching predetermined materials such as outer wall materials, floor materials, and ceiling materials to the frame frame 11 at the factory, by combining a plurality of housing units 10 in the front and rear, left and right, and up and down at the construction site as shown in FIG. Industrialized housing is built.

At this time, in order to prevent the sound from leaking to the lower floor especially when walking on the floor of the upper floor, for example, in the case of a two-story industrial house, the housing unit 10 arranged on the first floor is A sound insulation material such as rock wool was previously placed in the factory on the ceiling or the floor of the housing unit 10 placed on the second floor.

[Problems to be Solved by the Invention]

However, when the housing units 10 are combined at the construction site, the two housing units 10 that are horizontally adjacent to each other are
Since there is a gap in the connecting portion between them, there is a problem that sound leaks downstairs from this gap.

Therefore, it is necessary to place a sound insulating material in the gap between the housing units 10 at the construction site, and as a result, it is not always possible to meet the purpose of the industrialized house whose main task is to reduce the construction site work ratio. There was a problem.

An object of the present invention is to provide a sound insulation structure in an industrialized house, which can prevent sound leakage from a connecting portion between housing units and reduce a site work ratio.

[Means for solving the problem]

A sound insulation structure in an industrialized house according to the present invention is an industrialized house constructed by combining a plurality of housing units pre-produced in industry at a construction site, and at least one of the two housing units that are horizontally adjacent to each other. The sound-insulating material installed at the factory is arranged on the outer surface of the frame of the housing unit.

[Action]

Since the sound insulating material is arranged between the two horizontally adjacent housing units to provide the sound insulating area, sound does not leak from the connecting portion between the housing units. Further, since the sound insulating material is attached to the outer surface of the frame of at least one of the housing units at the factory in advance, there is no need to dispose the sound insulating material at the construction site, and the rate of field work is reduced.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a housing unit 10 arranged on the second floor of an industrialized house, and among the floor beams 13 and 14 of this housing unit 10, the outside of the floor beams 13 and 14 adjacent to other housing units 10. A sound insulation material 5 made of rock wool is attached to the side surface in advance at a factory.

As shown in FIG. 2, the sound insulating material 5 has a thickness A in a free state. In addition, the floor covering 1 made of, for example, particle board of each housing unit 10 has a length dimension that can reach the outer peripheral side end of the floor beam 13. The packing 2 is fixed to the upper surface of the floor beam 13 with an adhesive, and the end 1A of the floor material 1 is packed with the packing 2
It is fixed to the floor beam 13 via the packing 2 by a fastener with a Tex nail, for example.
The other part of the floor covering 1 is fixed by nailing to a joist (not shown) spanned between the floor beams 14. The floor surface agent 1 is specifically composed of a plurality of members arranged in parallel in the direction perpendicular to the paper surface of FIG. 2, and the length of the floor surface material 1 formed by these members in the direction perpendicular to the paper surface of FIG. The end in this direction of the floor covering 1 reaching the side end is fixed to the upper surface of the floor beam 14 via the packing 2 similarly to the end 1A.

In the space surrounded by the floor beams 13 and 14 below the floor panel 1, a sound insulation material made of rock wool is preliminarily installed in the factory.

The above work is performed in the factory, and a plurality of housing units 10 are combined at the construction site to build an industrialized house.

At this time, if the housing units 10 on the second floor are horizontally arranged side by side, as shown in FIG. 3, the sound insulation members 5 are pressed against each other to automatically form the sound insulation region 5A. That is, the sound insulation members 5 attached to the floor beams 13 are arranged in pressure contact with each other at the connecting portions between the floor beams 13 of the residential units 10 on the second floor arranged adjacent to each other without any gap. By its thickness B
The sound insulation area 5A is formed by the respective sound insulation materials 5 compressed so as to be less than half the thickness dimension A in the free state.

Between the upper surfaces of the end portions 1A of the floor material 1 of this housing unit 10,
A thin plate member 3 having a width dimension reaching the floor beam 13 of each housing unit 10 is bridged, and the thin plate member 3 is fixed to each end 1A with an adhesive and nailing. The same work is performed on the end portion of the floor covering 1 on the floor beam 14 side. The thin plate member 3 is, for example, a metal plate having a thickness of 0.8 mm.

After that, the finishing member 4 is coated on the upper surfaces of the floor surface member 1 and the thin plate member 3 to finish the floor.

As is clear from the above description, according to the present embodiment, the sound insulating material 5 can be arranged without gaps in the connecting portion between the horizontally adjacent housing units 10 to form the sound insulating area 5A. It is possible to prevent the sound from leaking from the second floor to the first floor in the event of a break. Further, since the sound insulation members 5 are pressed against each other and are in a compressed state, the sound insulation performance can be improved.

Furthermore, since the sound insulating material 5 is installed in the factory in advance, if the housing units 10 are horizontally installed at the construction site, the sound insulating materials 5 are mutually compressed and the sound insulating area 5A can be automatically formed. , The work of arranging the sound insulating material 5 does not need to be specially performed on the construction site, and the work on the site can be reduced compared to the conventional one.
Field work ratio can be reduced. Therefore, even in the work of providing the sound insulation structure, it is possible to meet the purpose of the industrialized house whose main task is to reduce the work rate of the construction site.

Further, since the rock wool used as the sound insulation material 5 can be used as a heat insulation material, not only the sound insulation performance but also the heat insulation performance can be improved.

In the embodiment described above, the sound insulation area 5A is provided between the floor beams 13 and 14 of the plurality of housing units 10 arranged on the second floor.
However, even if the sound insulation material 5 is attached to the ceiling beams 15 and 16 of the plurality of housing units 10 arranged on the first floor, the sound insulation area 5A is formed between these ceiling beams 15 and 16. Well again
Both of these may be implemented.

Further, in the above-described embodiment, the sound insulating material 5 is attached to the floor beams 13 and 14 of the two adjacent housing units 10 in the horizontal direction, but the floor beams 13 and 14 of either one of the housing units 10 are attached.
Alternatively, the sound insulation material 5 is attached only to the ceiling beams 15 and 16, and when the housing unit 10 is combined, the sound insulation material 5 is brought into contact with the floor beams 13 and 14 or the ceiling beams 15 and 16 of the adjacent housing unit 10 to provide the sound insulation area 5A. You may form.

Further, the sound insulating material 5 is not limited to rock wool, and various members having sound insulating performance such as glass wool can be used, but it is particularly preferable to use elastic and compressible material.
