DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition wall structure of a building unit and a method of constructing a partition wall of a building unit, which vertically separates a ceiling space and a living room space of the building unit.

[0002]

BACKGROUND ART Unit-type buildings such as houses are constructed by combining a plurality of building units and the like. In such a unit-type building, especially in an apartment house, it is legally required that each house has a fireproof structure. Therefore, the wall separating each house is also made to have a fireproof structure. One example of the wall structure of a building unit is JP-B-63-30.
0140 gazette. According to the technique disclosed in this publication, the upper and lower end surfaces are provided with a ceiling-bounding wall and a living room-bounding wall whose surfaces are finished to be flat surfaces, and these houses are separated from each other. When installing each wall,
After the ceiling wall is fixed to the ceiling beam, the living room wall is erected between the ceiling wall and the floor, the upper end is fixed to the ceiling wall, and the lower end is fixed to the floor. It is fixed. And when connecting each partition wall up and down, a soft spacer is interposed between the partition walls between the building units of each floor.

[0003]

However, in the above-described boundary wall structure, in order to fix the room boundary wall to the ceiling rear boundary wall, the height of the room boundary wall is set to a value between the floor material and the ceiling material. Since it must be formed shorter than the indoor height dimension, a gap is created between the living room boundary wall and the ceiling rear boundary wall. Then, in order to connect the living room boundary wall and the ceiling back boundary wall to each other in this gap, a sealing material must be provided after the living room boundary wall is erected, so that the operation is troublesome because the work is performed twice. In addition, since the sealing material is provided, there is a problem that the portion is raised and the appearance is poor.

[0004] Further, since the upper and lower end surfaces of each boundary wall are flat surfaces, in order to fix the living room boundary wall to the ceiling rear boundary wall,
While holding down the living room wall so that the worker does not fall, the side walls of the living room wall and the ceiling back wall are continuous, and
In order to be able to be installed at right angles to the floor material, the operation must be performed while always checking, which takes a lot of time, and there is a problem that the efficiency of the installation work is poor. In addition, since the upper and lower end surfaces of each boundary wall are flat surfaces, and when the room boundary wall is fixed to the ceiling rear boundary wall, there is no stopper or the like for positioning the room boundary wall. There was also a problem that it was difficult to obtain a high accuracy.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a building unit boundary wall structure and a building unit boundary wall construction method capable of improving the efficiency of mounting work and mounting with high accuracy.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a unit-type building constructed using the wall structure of the building unit of the present embodiment. The unit building 1 includes a plurality of lower and upper building units 2 and 3, a roof panel 4 attached to an upper portion of the upper building unit 3, and the like. The apartment house has a plurality of living rooms partitioned at predetermined intervals.

Here, each of the building units 2 and 3 includes a ceiling member and a floor, which are composed of four pillars erected at four corners and upper and lower beams connecting the upper and lower ends of these pillars. It is constructed by attaching materials, outer walls and the like. The structures of the lower and upper floor building units 2 and 3 and the wall structure are substantially the same, and therefore, the following description will be made for the lower floor building unit 2 for convenience.

According to FIGS. 2 and 3 showing a concrete wall structure, the interior of the building unit 2 is divided into a ceiling space 11 and a living room space 12 by a ceiling material 10. Numeral 5 partitions the interior of such a building unit 2 in the vertical direction. The partition wall 5 includes a first partition wall 13 that partitions the ceiling space 11 and a second partition wall that partitions the living room space 12.
It consists of 14 and.

The first boundary wall 13 is formed by a pair of left and right ceiling boundary wall panels 15 which are arranged to face each other with a predetermined gap therebetween. Each ceiling boundary wall panel 15 has a core member 17 formed to have a length extending between a pair of long-side beams 16A constituting the upper beam 16 of the building unit 2. For example, a double-layer gypsum board 18 as a fire-resistant surface material is adhered, and a heat insulating material 19 such as glass wool is adhered to a surface opposite to the gypsum board 18 with the core material 17 interposed therebetween.

Here, the lower end surface of the gypsum board 18 is
The lower end surface of the core material 17 is partly on the extension of the lower end surfaces of the ceiling material 10 and the gypsum board 18, but the rest is lower than that surface, that is, on the indoor side. Formed on the protruding protrusions 20 and thus the ceiling border panel 15
Is formed, for example, in the shape of a square knife. And such a ceiling boundary wall panel 15,
The building unit 2 is fixed to a small beam 21 attached between the long beams 16A of the upper beam 16 by nailing or the like.

The second wall 14 is formed by a pair of left and right living room wall panels 25 which are opposed to each other with a predetermined gap therebetween. Each living room boundary wall panel 25 has a frame 26 formed of, for example, wood, and on the indoor side surface of the frame 26,
For example, it is formed by attaching a double-layer plaster board 27 and attaching a heat insulating material 28 such as glass wool in the frame 26. The frame 26 has a width extending between the inner walls provided on the side of the pair of long side beams 16A and a height extending from the floor material 29 to the ceiling material 10. Is approximately the same thickness as the ceiling boundary wall panel 15.

Here, of the two plasterboards 27,
The upper end face of one sheet 27A on the indoor side can contact the lower end face of the ceiling border wall panel 15, while the other one 27B is formed lower than the ceiling border wall panel 15 and the living room. When connecting with the boundary wall panel 25, only one gypsum board 27A needs to be slid, and the connection between the two can be easily performed.

The upper end surface of the frame 26 is a ceiling boundary wall panel.
A stripping member 30 is provided below the projection 20 of the frame 15 and between the upper side surface of the frame 26 and the gypsum board 27.

Has become. That is, in the living room boundary wall panel 25, the projecting portion 31 is formed by the upper end portion of the gypsum board 27 and the upper end portion of the blanking material 30, and as a whole, the length is different but the same corner as the ceiling boundary wall panel 15 is used. It is shaped like a silhouette of a kitchen knife. The lower end portion of the ceiling boundary wall panel 15 and the upper end portion of the living room boundary wall panel 25 are respectively engaged with the projections 15 and 31 substantially in the form of a tom. It is configured to be fixed by a nail or the like (not shown) that penetrates the hollow material 30 and reaches the core material 17 of the ceiling boundary wall panel 15.

Between the lower ends of the pair of living room boundary wall panels 25,
A positioning member 32 having a length extending between the long side beams 16A, that is, a width substantially equal to the width of the living room boundary wall panel 25 is attached to the floor member 29. Therefore, if the lower end portions of the living room boundary wall panels 25 are fixed in a state where they abut against the positioning members 32, a predetermined gap is secured between the lower end portions of the living room boundary wall panels 25. Therefore, if the width of the positioning member 32 is set to a dimension such that the surfaces of the gypsum boards 27 and 18 are vertically continuous when the living room wall panel 25 and the ceiling wall panel 15 are connected. By simply abutting the lower end of the room wall panel 25 against the positioning member 32 and the upper end against the core 17, the room wall panel 25 can be easily attached.

Next, the construction procedure of the boundary wall will be described. First,
