BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to variable dry walls and, more particularly, to a variable dry wall, which can be easily constructed and disassembled, thus making it easy to partition the space in a structure depending on individual requirements and to remodel the space in the structure.

2. Description of die Related Art

As well known to those skilled in the art, in structures such as office buildings, apartment buildings, dwellings and factories, dry wall construction methods are widely used to construct a dry wall, which are inside walls to partition the space in the structures into several sections.

Such a dry wall is relatively light compared to a wall constructed through a wet construction method, for example, by piling blocks or bricks. Therefore, the dry wall construction method has advantages in that the load applied to the structure is reduced, the construction process is simple, and the construction time and the construction costs are reduced.

Furthermore, the dry wall makes it possible to partition the space in the structure in response to individual requirements, unlike the wall constructed through a wet constriction method. However, in the conventional dry wall, because studs are coupled to runners, which are fastened to the outer wall of the structure using a fastening means such as a large number of screws, work efficiency is reduced when constructing the dry wall, and it is difficult and inconvenient to disassemble the constructed dry wall. Therefore, there is a disadvantage in that remodeling ability is markedly reduced.

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 a variable dry wall which is constructed such that, after a stud is placed between runners installed in a structure, the stud can be securely fastened to the runners merely by rotating the stud, thus the construction and disassembly of the dry wall are simple, thereby making it easy to partition the space in the structure depending on individual requirements, and to remodel the space in the structure.

In order to accomplish the above object, the present invention provides a variable dry wall to partition a space in a structure, including: a pair of runners respectively provided on a ceiling and a floor of the structure, with a guide slot formed in each of surfaces of the runners that face each other; a stud inserted at opposite ends thereof into the guide slots of the respective runners. Such that the opposite ends of the stud are supported by the respective runners; a fastening means provided on each of the opposite ends of the stud and locked at an end thereof to the guide slot of the corresponding runner, so that the stud is fastened to the runners; and a board coupled to each of opposite surfaces of the stud using screws.

Preferably, the fastening means may comprise a bolt member, having: a bolt shaft screwed into the stud; and a head part provided on an end of the bolt shaft and unrotatably inserted into and locked to the corresponding runner. Furthermore, threads of the bolt members screwed into the opposite ends of the stud may be formed in opposite rotational directions.

In addition, at least one selected from among a thermal insulator, a sound insulator and a sound absorber may be provided between the opposite boards. Each of the runners may be attached to each of the ceiling and the floor of the structure using an adhesive sheet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

FIGS. 1 through 4d are views illustrating a variable dry wall according to the preferred embodiment of the present invention.

As shown in the drawings, the variable dry wall according to the preferred embodiment of the present invention includes a pair of runners 200, a plurality of studs 300 and a plurality of boards 500.

As shown in FIGS. 1 and 2, the runners 200 are fastened to the ceiling and the floor in a desired place.

In detail, an adhesive sheet 240 is provided on the surface of each runner 200 that faces the ceiling or the floor, so that the runner 200 is attached to the ceiling or the floor using the adhesive sheet 240.

Furthermore, a guide slot 220 is longitudinally formed in each of surfaces of the opposite runners 200 which face each other. Ribs 210, which are spaced apart from each other by a predetermined distance to define the guide slot 220, are provided in the runner 200 on opposite sides of die guide slot 220 in longitudinal directions of the runner 200.

In addition, insertion holes 230, each of which is formed by cutting the ribs 210 to widen them to opposite edges of the runner 200, are formed at predetermined positions in the guide slot 220 of the runner 200.

Meanwhile, the studs 300 are inserted at opposite ends thereof into the guide slot 220 of the opposite runners 200, which are fastened to the ceiling and the floor, so that the studs 300 are locked to and supported by the opposite runners 200.

Each stud 300 has a hollow rectangular pipe shape. Internal threads 310 and 320 are respectively formed in upper and lower ends of the stud 300.

Bolt members 400 and 400′, which are fastening means, engage respective internal threads 310 and 320 of the stud 300.

Each boll member 400, 400′ includes a bolt shaft 410, 410′, which is screwed to the stud 300, and a head part 420, 420′, which is provided on one end of the bolt shaft 410, 410′ and has a rectangular plate shape such that it is unrotatably inserted into and locked to the corresponding runner 200.

The threads of the bolt members 400 and 400′, which are screwed to the opposite ends of the stud 300, are oriented in directions opposite each other. Also, the internal threads 310 and 320 are formed in the stud 300 in directions opposite each other to correspond to the threads of the bolt members 400 and 400′.

That is, if the lower bolt member 400′ is a right-handed screw, the upper bolt member 400 is a left-handed screw. The internal threads 310 and 320, which respectively engage with the upper and lower bolt members 400 and 400′, are formed in the stud 300 in directions corresponding to those of the upper and lower bolt members 400 and 400′.

In the state in which the stud 300 is installed between the opposite runners 200 through the bolt members 400 and 400′, when the stud 300 is rotated in one direction, as shown in FIG. 3, the bolt members 400 and 400′ are tightened into or loosened from the stud 300.

The planar boards 500 are fastened to the opposite surfaces of the studs 300 using screws 510. At lease one selected from among a thermal insulator, a sound insulator and a sound absorber is provided between the boards 500 and the studs 300.

The process of assembling the variable dry wall according to the present invention having the above-mentioned construction will be described herein below.

As shown in FIG. 4a, the runners 200 are fastened to the ceiling and the floor of a structure in which it is desired to install the variable dry wall 100, at positions corresponding to each other using the adhesive sheets 240.

Thereafter, as shown in FIG. 4b, the head parts 420 and 420′ of the bolt members 400 and 400′, which are screwed to the opposite ends of one stud 300, are inserted into the corresponding insertion holes 230 of the runners 200 and are moved to desired positions, at which the stud 300 is installed between the runners 200.

Here, the bolt shafts 410 and 410′ of the bolt members 400 and 400′ are moved along the respective guide slots 220, thus the position of the stud 300 can be easily adjusted.

Subsequently, as shown in FIG. 4c, each stud 300, the position of which has been adjusted between the runners 200, is rotated in a predetermined direction. Then, because the upper and lower bolt members 400 and 400′ are unrotatable relative to the runners 200 due to the head parts 420 and 420′, the bolt members 400 and 400′ are vertically moved and thus tightened into the stud 300.

At this time, the bolt members 400 and 400′ are tightened into the stud 300 until the head parts 420 and 420′ thereof are securely locked to and compressed by the inner surfaces of the ribs 210 of the respective runners 200. In the same manner, the remaining studs 300 are installed at positions spaced apart from each other at regular intervals.

Thereafter, as shown in FIG. 4d, a board 500 is coupled to first surfaces of the adjacent studs 300 using screws 5 10. Another board 500 is coupled to second surfaces of the studs 300 using screws 510, at which time a thermal insulator, such as glass fiber, is placed between the boards 500, thus completing the construction of the dry wall 100.

Meanwhile, a process of disassembling the dry wall 100, which has been constructed according to the above-mentioned method, is conducted in the reverse order. Here, when each stud 300 is rotated in the direction opposite the rotation direction when constructing the dry wall 100, the bolt members 400 and 400′, which are in the state of being unrotatable relative to the runners 200, are loosened from the stud 300, so that the head parts 420 and 420′ of the bolt members 400 and 400′, which have been in close contact with the ribs 210, are moved away from the ribs 210. Thus, the stud 300 is released from the runners 200 and thus enters the state of being removable from the runners 200.

As such, in the present invention, because the processes of constructing and disassembling the dry wall 100 can be simply conducted, it is easy to remodel the space in the structure, thus making it easy to partition the space in the structure to meet individual requirements.

As described above, the present invention provides a variable dry wall which can be easily constructed and disassembled, so that it is easy to remodel a structure, thus making it possible to freely partition the space in the structure depending on individual requirements.

Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
