BACKGROUND OF THE INVENTION
The present invention relates to a partition wall spacer that is useful for forming a partition wall of a building, and a partition wall construction method that uses the partition wall spacer.
[0002]
[Prior art]
Conventionally, construction of a partition wall of a building has been performed by a method schematically shown in FIG. That is, runners 1 and 1 having a U-shaped cross section are provided on the ceiling and floor of the building by appropriate fixing tools such as nails and screws so that the openings are opposed to each other in the vertical direction. Are installed with a fixed interval between them and C-shaped studs (inter-columns) 2, 2,... ing.
[0003]
In general, the partition wall is required to have heat insulation, fire / fire resistance, sound insulation, etc. Especially regarding sound insulation, the way of sound transmission in the partition wall is through solid propagation transmitted through the solid and air. There is air transmission to be transmitted. As one of the construction methods for improving the sound insulation of the partition wall, in order to effectively suppress the above-mentioned solid propagation, the studs 2, 2,. A method of arranging studs in a staggered structure is generally employed.
[0004]
9 is an XX arrow view of the structure shown in FIG. 10 as seen from the plane indicated by the alternate long and short dash line, and the cross-sectional shape is lower than the runner 1 on both downward sides 1 ′ and 1 ′ of the runner 1 shown in FIG. Small cross-section C-shaped studs 2, 2,... Are alternately fixed inside the both sides 1 ′, 1 ′ of the runner 1 by appropriate means such as screws. As described above, by arranging the studs 2, 2,... In the runner 1 in a staggered structure, the solid propagation of sound on the partition wall is reduced and the sound insulation is improved. In the case of such a staggered structure, as shown in FIG. 9, there is a space between the inner surfaces of both sides 1 ′, 1 ′ of the pair of upper and lower runners 1 and the studs 2, 2,. In this space, an appropriate spacer 4 is disposed to construct a partition wall.
[0005]
As a method for filling this space, for example, a piece of gypsum board used as a wall material is cut into a size of about 50 × 50 mm, and this is piled up to a certain thickness and inserted into the space as a spacer 4. ing. However, in this method, when the studs 2, 2,... Are arranged between the runners 1, 1, or when the positions of the studs 2, 2,. It may fall off. Conventionally, the spacer 4 is fixed to the runner 1 or the studs 2, 2,... With a gum tape or the like in order to prevent them from shifting or slipping off. Construction efficiency decreases.
[0006]
In general, the partition wall is particularly required to have out-of-plane rigidity (stiffness against the load in the vertical direction with respect to the wall surface of the partition wall). However, the partition wall is configured by using a C-shaped stud that is currently widely used. Since the stud has a C-shaped cross section, sufficient out-of-plane rigidity cannot be obtained unless any reinforcing measures are taken. Therefore, as shown in FIG. 10, it is necessary to separately attach a plurality of stud spacers 5, 5,... For reinforcing studs having a C-shaped cross section to the upper and lower ends of the studs 2, 2,. It was.
As described above, the conventional technique has a problem in filling and holding the space formed between the runners 1, 1 and the studs 2, 2,... In order to give out-of-plane rigidity to a partition wall, many stud spacers 5 are required, and there also exists a problem that those handling is complicated.
[0007]
[Problems to be solved by the invention]
Therefore, the first object of the present invention is to effectively fill the space formed between the upper and lower runners and studs in the staggered partition wall without shifting or sliding down during construction. It is providing the partition wall spacer which can construct the partition wall excellent in sound-insulating property, and the construction method of a partition wall using the same.

DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described more specifically with reference to the drawings.
First, the spacer A of the first invention will be described.
The spacer A of the present invention has a configuration as shown in FIG. That is, a metal plate having a desired width and length is bent substantially perpendicularly to the length direction, and one bent side 12 formed by the bending is brought into contact with the side surface of the stud 2 as shown in FIG. A surface. The other bent side 17 is further bent inward at a substantially right angle so as to have a predetermined width s. This width s substantially corresponds to the difference in width between the runner 1 and the stud 2 shown in FIG. The bent side 11 formed by the bending is a surface that contacts the inner surface of one side 1 ′ of the runner 1 as shown in FIG.
[0012]
Further, a stud hooking portion 13 having a predetermined distance v from the bent side 12 that is the stud contact surface and parallel to the bent side 12 is provided integrally with the extension 18 of the bent side 17, as shown in FIG. Thus, the spacer A is hung on the top side surface of the stud 2 and held by the stud hooking portion 13.
Further, in a preferred embodiment of the present invention, in the spacer A, the bent side 11 which is the runner contact surface is bent inward at a substantially right angle so as to have a predetermined width t, and as shown in FIG. The front end of the bent side 15 is in contact with the back surface of the bent side 12 to prevent the bent side 11 from bending inward and to improve the out-of-plane rigidity of the partition wall that is finally configured.
[0013]
Further, as shown in FIGS. 3 and 4, the spacer A of the present invention is fixed to the side surface of the stud 2, so that it does not affect the opening of the stud 2, and thus a conventionally known stud reinforcement is used. The stud spacer 5 and the spacer A of the present invention can be installed on substantially the same line, so that the out-of-plane rigidity of the partition wall finally configured is improved.
[0014]
The spacer A of the present invention as described above can be formed by press-molding a metal plate such as a steel material and appropriately cutting it. For example, in the spacer A in the example shown in FIGS. 1 and 2, a notch for forming the stud hooking portion 13 is first formed in a flat metal plate having a desired width and length, and thereafter, as shown in the figure. It can be formed only by bending into a shape. In this case, the notch 16 is formed in the bent side 12 which is the stud contact surface, but this notch 16 does not have any adverse effect on the spacer A of the present invention. As another method, a flat metal plate having a desired width and length is bent into the shape shown in the drawing, except for the stud hooking portion 13, and then the line of the folding portion 14 is shown in the drawing. The shaped stud hook 13 may be fixed by welding. Of course, in this case, the notch 16 is not formed.
[0015]
Next, the spacer B of the second aspect of the present invention will be described.
The spacer B of the present invention has a configuration as shown in FIG. That is, in the spacer B of the present invention, a metal plate having a desired width and length is bent at a substantially right angle in the length direction, and the surface of one bent side 6 formed by the bending is shown in FIG. Further, a surface that contacts the inner surface of one side 1 ′ of the runner 1 is formed, and the bent side 6 is further bent inward so as to have a desired width b, thereby forming a bent side 7. The width c of the bent side 7 substantially corresponds to the width difference between the runner 1 and the stud 2 shown in FIG. The tip of the bent side 7 formed by the bending contacts the side surface of the stud 2.
[0016]
Further, at least one side end portion of the other bent side 9 is bent inward, and concave portions 11 are formed at both ends of the bent side 10 formed by the bending, so that the bent side 10 functions as a stud spacer. .
Further, in the spacer B, as shown in FIG. 6, the bent side 7 is further bent to have an arbitrary width d, and the surface of the bent side 8 formed by the bending is used as a stud contact surface. The contact between the surface of the bent side 8 and the side surface of the stud 2 is strengthened.
[0017]
Like the spacer B, the spacer B of the present invention does not deviate or fall off from the top of the stud, and further functions as a spacer between the runner and the stud, and at the same time as a spacer for reinforcing the stud. Since it functions, the workability of the partition wall is improved and the out-of-plane rigidity of the partition wall finally configured is improved.
The spacer B of the present invention as described above can be formed by press-molding a metal plate such as a steel material and appropriately cutting it.
[0018]
Next, the construction method of the partition wall of this invention is demonstrated.
The partition wall construction method of the present invention is characterized by using the spacer A or B of the present invention. First, as in the prior art, as shown in FIG. 10, a pair of runners 1 and 1 are provided on the ceiling and floor in the building with their openings facing each other. Between the upper and lower runners 1, 1, a required number of studs 2, 2,... Are arranged in a staggered structure as shown in FIG.
[0019]
Next, when the spacer A of the present invention is used, when the studs 2, 2,... Are arranged, the present invention is applied to the top side surfaces of the studs 2, 2,. Each spacer A is disposed. 3 is a perspective view showing a state in which the spacer A shown in FIG. 1 is attached, and FIG. 4 is a perspective view showing a state where the spacer A shown in FIG. 2 is attached to the top side surfaces of the studs 2, 2,.
The spacer A is held so as to stick to the top side surfaces of the studs 2, 2,..., And a conventionally known stud spacer 5 is installed in the openings of the studs 2, 2,. be able to.
[0020]
On the other hand, when the spacer B of the present invention is used, the spacer B of the present invention is attached to the top side surfaces of the studs 2, 2,. The distance g (FIG. 5) between the left and right recesses 11 of the spacer B of the present invention is formed to be somewhat larger than the distance j between the openings of the studs 2, 2,. Since the openings of the studs 2, 2,... Having a C-shaped cross section are spread by some force, spacers are provided at both ends 13, 13 of the studs 2, 2,. The spacer B is held on the side surfaces of the tops of the studs 2, 2,.
[0021]
As shown in FIG. 7, the spacer B of the present invention has a fall prevention means 14 for preventing the spacer B from sliding down at one end of the bent side 8 where the spacer B contacts the studs 2, 2,. By providing this, it is possible to completely prevent the spacer B from sliding off. As an example of the fall preventing means, it is effective to form the hanging tool 14 having a clip-like shape integrally with the spacer B. By providing such a fall prevention means 14, the spacer B does not slide downward from the top side surfaces of the studs 2, 2... Even if the width g is the same as or slightly narrower than the distance j.
[0022]
Next, if necessary, the spacer A or B of the present invention can also be disposed below the studs 2, 2,..., But the spacer in this case exists on the floor surface, so A conventional spacer (not shown) may be used because there is no fear of sliding off. In addition, an arbitrary number of stud spacers 5 for stud reinforcement similar to the prior art can be provided in the middle portion of the studs 2, 2,.
In addition, the spacer A or B in the present invention described above may be disposed at an appropriate interval in the middle portion of the stud 2 in addition to being disposed at the top and bottom of the stud 2. . Also in this case, the out-of-plane rigidity of the partition wall finally formed is further improved.
[0023]
After the necessary number of studs 2, 2,... Are fixed between the upper and lower runners 1 and 1 as described above, a wall material 3, 3 such as a gypsum board is attached to this structure by means such as screws. The construction method of the present invention is completed by fixing by the above. Of course, the portion of the wall material that has been recessed by screwing in thereafter can be repaired with a putty or the like, and further, a decorative operation such as crossing can be applied to the surface of the wall material.
The runners 1, 1, studs 2, 2,..., Wall materials 3 and 3, stud spacers 5, and other fixtures used in the construction method of the present invention are the same as in the prior art. Any of these can be used as they are in the present invention.
