Description

[0001] An assembly stud for sound insulation [

The present invention relates to an assembled type soundproof stud, and more particularly, to an assembled soundproof stud having a novel structure that improves sound insulation performance and productivity by interrupting the sound transmission path of the inter-generational wall.

Conventionally, various kinds of building structures such as houses and factories have been constructed by a wet method using a frame, a concrete, and a rebar.

These wet methods have many problems, such as installing molds, reinforcing bars, pouring concrete, and curing concrete to complete the construction. The construction period is long and costly, and it is difficult for the skilled craftsman to work on construction.

In recent years, there have been many construction of dry buildings using dry methods that do not use water, such as prefabricated houses using panels and steel houses, and their demand is also rapidly increasing.

This method is advantageous in that the construction is simple, the construction period is short, and the cost is reduced.

In particular, since drywall is easy to construct, it is widely applied as a barrier between generations partitioning generations in apartment buildings, residential complexes, and so on.

Typically, a dry wall is constructed by inserting vertically studs between upper and lower runners at regular intervals, fixing one or two layers of gypsum boards on one side of the studs, A fixing pin or the like is installed in the space between the studs, and the surface finishing material is attached to the stud.

At this time, the mainly installed studs are C type studs of 0.8 T (thickness, mm) or more, are fixed to the runner, and then the gypsum boards are fixed on both surfaces of the studs.

However, such a drywall has a problem in that vibration and noise generated between generations are easily transmitted through the studs to deteriorate sound insulation performance.

In recent years, the performance standard of the sound insulation structure for the inter-generational wall installation has been subdivided from the existing three grades to the four grades, so that it is important enough to be prescribed by law.

In order to meet this sound insulation performance standard, noise is reduced by forming a curved portion in the stud center plate or by inserting a 'W' shape into the end surface of the stud to lengthen the sound transmission path.

Conventionally, the sound is dispersed in the perforated hole in the stud center plate to reduce the solid transmission sound.

However, the conventional stud sound insulation structure has a limitation in productivity because the roll forming manufacturing process is complicated and the cost is high.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an assembled soundproof stud having a novel structure that can improve the sound insulation performance and productivity by cutting the sound transmission path in the middle.

In order to achieve the above object, an assembled soundproof stud according to the present invention comprises a first plate portion, a second plate portion bent vertically from one side of the first plate portion, and a second plate portion bent vertically toward the opposite side of the first plate portion from one side of the second plate portion. And the third plate portions of the two studs are engaged with each other to be used as a stud, which is a wall structure, with the studs facing each other.

The assembled sound insulating stud of the present invention has the following effects.

First, the studs are separated into left and right sides to cut off vibration or noise transmission in the middle, thereby enhancing sound insulation performance.

Secondly, the left and right separately-configured studs are connected and assembled by fastening means such as bolts or clips, so that the production is easy and the installation is convenient.

Thirdly, when the left and right separated studs are connected to each other, the sound absorbing member made of rubber is interposed therebetween to absorb the vibration or noise that is cut off in the middle, thereby further enhancing the sound insulation performance.

FIG. 2 and FIG. 3 are a cross-sectional view and a perspective view showing an embodiment of the assembling structure of the FIG.
Figs. 4 and 5 are a cross-sectional view and a perspective view showing another embodiment of the assembling structure of the Fig. 1 sound insulating stud, Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of an assembled soundproof stud according to the present invention.

1, the stud 10 of the present invention includes a first plate portion 11 extending in the longitudinal direction, a second plate portion 13 bent vertically from one side of the first plate portion 11, And a third plate portion 15 formed at one side of the plate portion 13 and bent outwardly, that is, perpendicularly toward the opposite side of the first plate portion 11.

At this time, the third plate portion 15 may be partially formed at regular intervals along the longitudinal direction of the second plate portion 13, and in this case, the third plate portion 15 has the effect of saving material.

When the first and second studs 10 having such a configuration are faced to each other and the third plates 15 of the two studs 10 are brought into contact with each other and then fastened through the fastening means, .

2 to 9 are a sectional view and a perspective view showing various coupling schemes between the assembled soundproof studs of FIG.

2 and 3 show a case where the bolts 20 are used as the binding means and when the two studs 10 are assembled by fixing the third plate portions 15 which are in contact with each other with the bolts 20 at regular intervals, do.

When the wall construction is performed using such an assembled soundproof stud, the vibration or noise transmitted to the stud is interrupted at the middle, that is, at the end of the third plate portion 15 of the stud 10, thereby improving the sound insulation performance.

In this case, as shown in FIGS. 4 and 5, the third plate 15 of the stud 10 may further include a sound absorbing member 30 made of a rubber material so that the sound insulating performance can be further enhanced.

4 and 5 are assembled in the same manner as FIG. 2 and FIG. 3, and a sound-absorbing member 30 is interposed between the third plates 15 so as to be opposed to each other between the two studs 10, The path is disconnected at the third plate portion 15, and at the same time, vibration and noise are absorbed by the sound-absorbing member 30, so that the sound-insulating performance can be more reliably improved.

Figs. 6 and 7 show a case where the clip 40 is used in place of the bolt 20 as the binding means, which is formed in the shape of a nail clip.

6 and 7, the third plate 15 of the two studs 10 is fitted between the both side edges of the clip 40 to connect the two studs 10 to each other .

Figs. 8 and 9 show a case in which a bandage 50 is used instead of the bolt 20 or the clip 40 as the binding means, which has a cross section of a substantially T shape.

8 and 9, the stitches 50 are fitted between the third plate portions 15 facing each other of the two studs 10 to couple the two studs 10 together.

Here, it is preferable that the bobbin 50 is made of a dissimilar material different from the stud material for sound insulation.

The base plate 50 is connected to the third plate portions 15 of the two studs 10 on both sides of the web 51.

At this time, one end of the web 51 of the strip 50 is folded toward both sides to form a flange 53 on a flat surface and is in contact with the second plate 13 of the two studs 10 connected to each other, The flange 55 is folded back toward the both sides so that the third plate 15 of the two studs 10 connected thereto is not pulled out.

Therefore, the assembled soundproof stud according to the present invention can be formed through simple assembly even if it is not difficult to produce through the roll forming process, so that the sound insulation performance can be expected, and productivity and cost can be improved remarkably.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as set forth in the following claims. It will be understood by those skilled in the art that it is readily known.
