Description

The present invention relates to a partition wall base structure for a building, a partition wall, and a method for fabricating the partition wall base structure.

FIG. 4 shows a T-shaped structural portion 101 of a conventional partition wall foundation structure. This T-shaped structure 101 has four studs 102 . Three of the four studs 102 are aligned in the extending direction of the partition wall and are in contact with each other. One of the four studs 102 is positioned in contact with the three studs 102 and is fixed to the center stud 102 by a through-length screw 103 . A gypsum board 104 is screwed to the stud 102 .

Patent document 1 discloses a partition wall using a hat-shaped connecting fitting in a partition in which a plurality of partition studs are erected at intervals and face plates are attached to both sides of each partition stud. . Further, in Patent Document 2, the thickness of the base plate or runner is added to the portion overlapping the base plate or runner of the stud so that the base surface composed of the stud and the base plate or runner joined to the stud is on the same plane. Studs are disclosed that are formed with substantially equal recesses.

However, the T-shaped structure 101 of the conventional partition wall foundation structure shown in FIG. However, there is a problem that workability is deteriorated because the number of places where the through-length screw 103 is driven increases. In addition, the through-length screws 103 are more expensive than general screws, and the larger the number, the higher the installation cost.

Moreover, in the technique of Patent Document 1, a large hat-shaped connecting fitting that wraps around the corner stud is used, and since such a large hat-shaped connecting fitting is bulky, there is a problem that the transport efficiency is reduced. Also, the above-mentioned hat-shaped connecting fitting is not suitable for attaching a reinforcing face member for reinforcing handrail attachment or the like.

Further, in the technique of Patent Document 2, reinforcing recesses are formed at the four corners of the stud, which makes the stud production cost relatively high. In addition, the reinforcing concave portion exists even in a place where the reinforcing face member for reinforcement is not attached, which is wasteful.

The present invention is a partition wall in which a plurality of studs can be efficiently fixed to each other at the T-shaped part or the cross part of the partition wall, and the construction for attaching a reinforcing face member for reinforcement to the partition wall can be performed without processing the stud itself. It is an object of the present invention to provide a substructure, a partition wall and a method of making a partition wall substructure.

The partition wall foundation structure of the present invention comprises a stud facing away from the surface to which the facing material is attached and facing away from the non-attached surface to which the facing material is not attached;
a hat-shaped member having a central flat plate portion and side flat plate portions formed parallel to the central flat plate portion via steps on both sides of the central flat plate portion, and having a substantially hat-shaped cross section; , is equipped with
The two studs are positioned apart from each other with their non-attached surfaces facing each other in the extending direction of the partition wall,
The side plate portion of the hat-shaped member is positioned across the face material attachment surfaces of the spaced apart studs on at least one orthogonal extending direction side orthogonal to the extending direction. the hat-shaped member is secured to the spaced apart stud by
A stud other than the two studs is positioned with one non-sticking surface of the stud in contact with the central flat plate portion of the hat-shaped member, and penetrates both non-sticking surfaces of the other stud. , wherein the another stud is connected to the two studs positioned apart from each other through the hat-shaped member by a through-length screw penetrating the central flat plate portion of the hat-shaped member. (referred to as the first configuration in this section).

With the above configuration, the separate stud is connected to the two studs positioned apart from each other through the hat-shaped member at the T-shaped portion or the cross portion of the partition wall, so that the conventional stud can be replaced. The number of studs can be reduced by one compared to the structure in which three studs are arranged. Moreover, since the number of through-length screws can be reduced, the partition wall can be constructed more efficiently. In addition, the hat-shaped member can be made smaller than a hat-shaped member that wraps around the stud, and the transportation efficiency is improved.

The height of the hat-shaped member may be lower than the height of the stud, and a plurality of hat-shaped members may be fixed to the stud (referred to as a second configuration in this section). According to this, the amount of material used can be reduced as compared with the configuration in which the hat-shaped member is provided over the entire height of the stud.

In addition, the partition wall base structure of the present invention includes a stud having a facing surface to which the facing material is applied facing away and a non-adhering surface to which the facing material is not adhered facing away,
a hat-shaped member having a central flat plate portion and side flat plate portions formed parallel to the central flat plate portion via steps on both sides of the central flat plate portion, and having a substantially hat-shaped cross section; , is equipped with
The hat-shaped member is fixed to at least one non-sticking surface of the stud by a side flat plate portion of the hat-shaped member, and a reinforcing face member is fitted in the recessed region of the hat-shaped member formed by the steps. (referred to as the third configuration in this section).

With the above configuration, the construction for attaching the reinforcing face member can be performed without processing the stud itself. That is, the stud itself can be used in common for other locations, and the hat-shaped member need only be attached to the location where the reinforcing face member is attached, so that an increase in processing cost of the stud can be suppressed. In addition, since the hat-shaped member may be attached only to the necessary locations, it is possible to eliminate the need for reinforcing recesses even in locations where no reinforcing face member is attached.

The height of the hat-shaped member may be lower than the height of the stud, and a plurality of hat-shaped members may be fixed to the stud (referred to as a fourth configuration in this section). According to this, the amount of material used can be reduced as compared with the configuration in which the hat-shaped member is provided over the entire height of the stud.

Moreover, the partition wall of the present invention is characterized by having both the partition wall base structure of the first configuration or the second configuration and the partition wall base structure of the third configuration or the fourth configuration. According to this, it is possible to obtain a partition wall that obtains the advantages of both of these partition wall base structures.

In the partition wall, the shape of the hat-shaped member used in the partition wall base structure of the first configuration or the second configuration, and the hat-shaped member used in the partition wall base structure of the third configuration or the fourth configuration and dimensions may be the same. According to this, cost reduction and construction efficiency improvement can be achieved by commonality of the hat-shaped member.

Further, in the method of manufacturing the partition wall base structure of the present invention, when the hat-shaped member is fixed to the stud, the hat-shaped member is fixed by a double-sided tape or a magnetic tape attached to the side flat plate portion of the hat-shaped member. to the stud.

With such a method, the work of fixing the hat-shaped member while pressing it by hand can be eliminated, so that work efficiency can be improved. Although the hat-shaped member can be temporarily fixed to the stud with a protective tape or the like, this does not result in a structure in which the protective tape is left between the side flat plate portion and the stud. If the double-faced tape or the magnetic tape that can be strongly adhered is used and this tape is left between the side flat plate portion and the stud, the number of screws for fixing the hat-shaped member can be reduced or eliminated. It can be fixed.

According to the present invention, a plurality of studs can be efficiently fixed to each other at the T-shaped portion and the cross portion of the partition wall, and the reinforcing face member can be attached to the partition wall without processing the stud itself. Play.

(Embodiment 1)
An embodiment according to one aspect of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a T-shaped portion of a partition wall provided with a partition wall foundation structure 1 of this embodiment.

The partition wall base structure 1 comprises a steel stud 3 and a steel hat-shaped member 4 . The partition wall is manufactured by fixing the gypsum board 2 or the like as a face material to the stud 3 of the partition wall base structure 1 with screws 5 .

The stud 3 has a facing surface 3a to which the gypsum board 2 is fastened by a screw 5 facing back, and a non-attaching surface 3b to which the gypsum board 2 is not attached, facing back, and has a substantially square frame shape in cross section. is.

As shown in FIG. 2, the hat-shaped member 4 includes a central flat plate portion 4a and side flat plate portions 4b formed parallel to the central flat plate portion 4a via steps on both sides of the central flat plate portion 4a. and has a substantially hat-shaped cross section. The height of this hat-shaped member 4 is lower than the height of the stud 3, and a plurality of hat-shaped members 4 are screwed to one stud 3 in the vertical direction. The height of the hat-shaped member 4 is, for example, 150 mm, and the width thereof is the same as the width of the non-sticking surface 3 b of the stud 3 . Further, in this embodiment, a double-sided tape 41 is attached to the joint surface side of the side flat plate portion 4b.

In the partition wall base structure 1 of this embodiment, runners (not shown) are fixed to the floor and the ceiling in the extending direction of the partition wall, and the two studs 3 in the runners are attached to the non-adhered surfaces of each other. 3b are opposed to each other and are spaced apart. Further, another runner (not shown) is fixed to the floor and ceiling so as to form a T-shape on one side perpendicular to the extending direction.

The hat-shaped member 4 is positioned across the face material attachment surfaces 3a, 3a of the two studs 3, 3 positioned apart from each other, and is struck against the side flat plate portion 4b of the hat-shaped member 4. The hat-shaped member 4 is fixed to the spaced apart studs 3 by a screw S1.

Further, on the other runner side of the partition wall base structure 1, one stud 3 (3A) different from the two studs 3 is provided so that one non-adhering surface 3b of the stud 3 is the hat. It is positioned in contact with the central flat plate portion 4a of the shaped member 4. As shown in FIG. Then, the stud 3 (3A) is attached to the hat-shaped member by a through-length screw S2 that penetrates both non-adhering surfaces 3b of the stud 3 (3A) and penetrates the central flat plate portion 4a of the hat-shaped member 4. It is connected via the member 4 to the two studs 3, 3 which are positioned apart from each other.

The through-length screw S2 is partly provided with a A special screw that has a non-threaded part.

In the partition wall base structure 1, for example, at the T-shaped portion, the stud 3 (3A) is connected to the two studs 3, 3 spaced apart via the hat-shaped member 4. Therefore, the number of studs can be reduced by one compared with the conventional structure in which three studs are arranged in the direction in which the partition extends. Moreover, since the number of through-length screws S2 can be reduced, there is an advantage that the partition wall construction efficiency can be improved and the cost can be reduced.

The height of the hat-shaped member 4 is lower than the height of the stud 3, and a plurality of hat-shaped members 4 are screwed to the stud 3, so that the long hat-shaped member extends over the entire height of the stud 3. It is possible to reduce the amount of steel used rather than providing

In the above example, the T-shaped portion of the partition wall is shown, but the partition wall base structure 1 using the hat-shaped member 4 can be similarly applied to the cross portion of the partition wall.

A method of manufacturing the partition wall base structure 1 will be described below. In this manufacturing method, when the hat-shaped member 4 is fixed to the stud 3, the hat-shaped member 4 is fixed to the stud 3 by a double-sided tape 41 attached to the side flat plate portion 4b of the hat-shaped member 4. including the step of

With such a method, the work of screwing the hat-shaped member 4 while holding it down by hand can be eliminated, so that the efficiency of the work can be improved. Although the hat-shaped member 4 can be temporarily fixed to the stud 3 with a protective tape or the like, the protective tape is not left between the side flat plate portion 4b and the stud 3 in this case. If a double-faced tape 41 capable of strong adhesion is used and left between the side flat plate portion 4b and the stud 3, the number of screws for fixing the hat-shaped member 4 can be reduced or the number of screws can be reduced. It is possible to set it to "no". A similar effect can be expected when a magnetic tape is used in place of the double-sided tape 41 .

(Embodiment 2)
Embodiments according to other aspects will be described below with reference to the accompanying drawings.
As shown in FIG. 3, the partition wall base structure 1A of the second embodiment uses the studs 3 and hat-shaped members 4 used in the first embodiment. That is, in the partition wall base structure 1 of the first embodiment and the partition wall base structure 1A of the second embodiment, the studs 3 and hat-shaped members 4 having the same shape and size are used.

In this partition wall base structure 1A, for example, runners (not shown) are fixed to the floor and ceiling in the extending direction of the partition wall, and one stud 3 is positioned at a predetermined position in the runner. Another stud 3 (not shown) is positioned at a predetermined distance from one stud 3 . Hat-shaped members 4 are fixed to the opposing non-adhering surfaces 3b of the two studs 3 positioned at the predetermined distance by screws S1 driven into the side flat plate portions 4b of the hat-shaped members 4, respectively. ing.

By fixing the hat-shaped member 4, a concave region formed by the steps of the hat-shaped member 4 is formed on the non-adhering surface 3b side of the two studs 3 positioned at the predetermined distance. A reinforcing face member 6 is fitted in the recessed region between the two studs 3 for reinforcing the handrail. The thickness of the reinforcing surface material 6 is such that the reinforcing surface material 6 is substantially flush with the surface material attaching surface 3a when the reinforcing surface material 6 is provided in the recessed region.

In the case of the partition wall base structure 1A, the construction for attaching the reinforcing surface member 6 can be performed without processing the stud itself. That is, the stud 3 itself can be used in common for other locations, and the hat-shaped member 4 needs to be attached only to the location where the reinforcing panel 6 is attached, so that an increase in processing cost of the stud 3 can be suppressed. In addition, since the hat-shaped member 4 can be attached only to the necessary locations, it is possible to eliminate the need for reinforcement recesses even in locations where no reinforcing face member is attached.

In addition, by using the hat-shaped member 4, the amount of steel used can be reduced compared to providing a long hat-shaped member covering the entire height of the stud 3. Of course, in Embodiments 1 and 2, an elongated hat-shaped member covering the entire height of the stud 3 may be used.

Also in the partition wall base structure 1A, when the hat-shaped member 4 is fixed to the stud 3, the hat-shaped member 4 is fixed by the double-sided tape 41 or the magnetic tape attached to the side flat plate portion 4b of the hat-shaped member 4. It may be fixed to the stud 3 mentioned above.

Further, if the partition wall has both the partition wall base structure 1 and the partition wall base structure 1A, the advantages of each of the partition wall base structures 1 and 1A can be obtained.

In such a partition wall, if the hat-shaped member 4 used in the partition wall base structure 1 and the hat-shaped member 4 used in the partition wall base structure 1A have the same shape and dimensions, the hat-shaped member By sharing the members 4, it is possible to reduce costs and improve construction efficiency.
