An edge column member 62 forms an outer edge of a corner formed by the walls being adjacent to each other and has an approximate “” shaped sectional configuration and is configured to extend in a lengthwise direction, and at each of both sides in a widthwise direction thereof a coupling groove to which a coupling piece of the other side of a second column member 63 in a widthwise direction is inserted and combined is configured to be a dovetail shape or a “T” shaped section and to extend in a lengthwise direction.
In addition, although it is described above that a coupling piece is formed in the other side of a second column member 63 in a widthwise direction and a coupling groove is formed in both sides of an edge column member 62 in a widthwise direction, the present invention is not limited thereto, and it is also possible that a coupling groove is formed in the other side of a second column member 63 in a widthwise direction and a coupling piece is formed in both sides of an edge column member 62 in a widthwise direction and that a coupling groove is formed in one side of an edge column member 62 in a widthwise direction and a coupling piece is formed in the other side.
Where one of a first column member 61 and two of second column members 63 and one of an edge column member 62 are combined and form a column assembly 60, a wall may form a corner that is bent with “” shape as seen in
Also, where two of first column members 61 and two of second column members 63 are combined and form a column assembly 60 a wall may be configured to be crossed with “T” shape, and where four of first column members 61 are combined and form a column assembly 60 a wall may be configured to be crossed with “+” shape.
Here, where a wall may be configured to be crossed with “T” shape, a coupling piece formed on the other side in a widthwise direction of one second column member 63 of two second column members 63 is inserted and combined to a coupling groove formed on the other side in a widthwise direction of the other second column members 63.
As described above, a column assembly 60 consists of a combination comprising at least one of a first column member 61, an edge column member 62 and a second column member 63, thereby a wall may be bent or crossed depending on preference and an installation is available without difficulty even in case that a wall is not perpendicular to or has a crossing angle that is somewhat away from a right angle.
A prefabricated wall for interior according to the present invention may further comprise an end column member 70.
As seen in ” shaped sectional configuration and extends in a lengthwise direction, and an inner surface of one side in a widthwise direction is combined and fixed to an elastic coupling member 31. Thus, a protruding portion 312 of an elastic coupling member 31 is inserted into a coupling groove 21 of a stud 20 thereby an end column member 70 is combined to a stud 20.
Also, a coupling piece or a coupling groove is formed at the other side end in a widthwise direction to be combined with a coupling piece or a coupling groove formed at one side end of other end column member 70 in a widthwise direction. Here, a coupling piece or a coupling groove is formed as a dovetail shape or a “T” shaped section to extend in a lengthwise direction, and preferably it should be difficult to be separated from each other once combined.
A construction method of a prefabricated wall for interior according to the present invention is explained as below.
First, a runner 10 should be installed to face each other in a predetermined position of a ceiling and a floor as per a design specification. That is, a reference line is indicated on a ceiling or a floor, and a runner 10 is adhered to a ceiling or a floor according to indicated reference line, then a base portion is fixed by a screw etc. at both sides of an area where a mounting frame portion 12 is formed.
Also, a plurality of studs 20 are fixed between runners 10 each of which is fixed to a ceiling and a floor. That is, a rear surface of a lengthwise direction end of each of a plurality of studs 20 is adhered to a side surface of a widthwise direction of a mounting frame portion 12 of the runner 10, and then is fixed in a vertical direction by a screw etc.
Then, a washboard coupling portion 510 of a molding member 50 is inserted into a molding coupling groove 420 of a washboard 40 so that a washboard 40 combined to a molding member 50 is connected to both ends of a runner 10 in a widthwise direction. That is, a runner coupling piece 410 of a washboard 40 is inserted into a washboard coupling groove 110 of a runner 10 so that a washboard 40 is combined to both ends of a runner 10 in a widthwise direction, thereby a washboard 40 combined to a molding member 50 is installed to an area adjacent to a ceiling and a floor and a corner finishing portion 520 of a molding member 50 contacts a ceiling and a floor.
Then, a front surface portion of a plurality of studs 20 is provided with a finishing panel 30 to which an elastic coupling member 31 is fixedly coupled in a vertical direction at both ends of left and right sides of an inner side surface thereof. That is, a protruding portion 312 of an elastic coupling member 31 fixed at both side ends of a finishing panel 30 is inserted into a coupling groove 21 of a plurality of studs 20 so that a finishing panel 30 is combined to a front surface portion of a plurality of studs 20, thereby a side surface portion of a prefabricated wall for interior according to the present invention is completed.
Here, an elastic coupling member 30 which is combined and fixed to both ends of left and right sides of an inner side surface of a finishing panel 30 is configured to be a little shorter than the finishing panel 30 in their length, thus, in the course of combining a finishing panel 30 with a front surface portion of a plurality of studs 20 it is prevented that a lower end portion of an elastic coupling member 30 which is combined and fixed to both ends of left and right sides of an inner side surface of a finishing panel 30 is supported by an upper portion of a washboard positioned at a lower inner side of a finishing panel, thereby it is prevented that a finishing panel 30 slips down into a lower side in a lengthwise direction of a stud 20 installed in a vertical direction.
In addition, in case that a plurality of finishing panels 30 should be combined to a front surface portion of a plurality of studs 30 due to that a length of a pre-ready finishing panel 30 is shorter than a height of indoor space, another finishing panel 30 is installed on an upper side of a finishing panel 30 installed on a lower side, thereby a finishing panel of an upper side is supported by a finishing panel 30 of a lower side.
Also, a step of compressively installing a gapper 80 in areas that are not finished by a panel side finishing wing 313 at an upper end portion and a lower end portion between finishing panels 30 adjacent to each other may be further included.
Such installing a gapper 80 can fill to finish a gap between finishing panels 30 adjacent to each other without omission.
In addition, where a home appliance or an electric outlet etc. is necessary to be installed on a side surface portion of a wall during the process, a step of installing them may be added.
First, an opening 35 of a finishing panel 30 is provided with an electric outlet or home appliances such as a TV, or a computer, or a flat panel display device, a cooling/heating device, or a humidifier, or an air purifier.
Next, an insulated wire is electrically connected to the home appliances or the electric outlet etc. for a power supply. That is, an insulated wire is passed via a through hole 125 formed on a top side portion of a mounting frame portion 12 of a central portion of a runner 10 into a space between rear surfaces of a stud 20 fixed at both side surfaces of a widthwise direction of the mounting frame portion 12 and into an internal space of the mounting frame portion 12 so as to electrically connect an insulated wire to the home appliances or the electric outlet etc.
Although it is described in the above that an insulated wire is electrically connected to the home appliances or the electric outlet etc. after an opening 35 of a finishing panel 30 is provided with an electric outlet or home appliances etc., it is also possible that an opening 35 of a finishing panel 30 is provided with an electric outlet or home appliances etc. and an insulated wire may be electrically connected to the home appliances or the electric outlet after an insulated wire is passed via a through hole 125 into a space between rear surfaces of a stud 20 fixed at both side surfaces of a widthwise direction of the mounting frame portion 12 and into an internal space of the mounting frame portion 12.
In addition, where it is required that walls are adjacent to each other to form a corner or be crossed to each other for partitioning indoor space of a building, a column assembly 60 consisted of a combination comprising at least one of a first column member 61, an edge column member 62 and a second column member 63 is combined to a side end portion of a wall. That is, a protruding portion 312 of an elastic coupling member 31 fixed to a side end portion of a finishing panel 30 forming a wall is inserted into a first coupling groove 615 or a second coupling groove 635 in order to be combined to a column assembly 60, thereby walls are adjacent to each other to form a corner or be crossed to each other.
Also, where an end portion of a wall is required to be finished, an end column member 70 is combined to a side end portion of a wall consisted of a finishing panel 30. That is, a protrusion portion 312 of an elastic coupling member 31 which is connected and fixed to an inner surface of one side in a widthwise direction of an end column member 70 is inserted and combined into a coupling groove 21 of a stud 20 to finish an end of a wall.
The above explained construction process may be conducted at once by a minimum number of workers. An existing prefabricated wall may not be completed with simple assembling only but separately requires different properties of actions such as finishing treatment with silicon of a corner portion between one end of a washboard and a ceiling or a floor, thus such whole processes should be conducted by different workers. Therefore, it should take additional time of working for such different workers to arrive and conduct the rest of actions after assembling actions are completed, which raises a problem to increase a construction period. However, a prefabricated wall for interior according to the present invention can be worked at once by a small number of personnel, and reduce labor costs and shorten a construction period.
It is one of advantages that a prefabricated wall for interior according to the present invention minimizes the uses of screws to then facilitate installation, disassembly and re-assembly of a wall.
Also, a small number of personnel may simultaneously perform the installation or disassembly work to reduce labor costs, and shorten the construction period.
Also, it is advantageous that separate silicon finishing becomes unnecessary by a molding member that is combined and installed to a lower part of a washboard.
Also, it is advantageous that a wall is bent or crossed depending on preference by a combination comprising a first and a second corner column members and an edge column member, and that an installation is available without difficulty even in case that a wall is not perpendicular to or has a crossing angle that is somewhat away from a right angle.
Also, it is advantageous that a sound-proof capacity is improved by installing a sound-proof member in a space between rear surfaces of the studs installed on both sides of the runner.
Also, it is advantageous that an electric wiring is facilitated that is necessary for operation of electrical devices or home appliances installed on the finishing panel by passing an insulated wire through after perforating a top side portion of a mounting frame portion of a central portion of the runner, if needed.
Also, it is advantageous to install various electrical devices such as a TV, a computer, a flat panel display device, a humidifier, or an air purifier in an opening of the finishing panel, or install an electric outlet in necessary positions of the finishing panels for convenient use.
Although the present invention has been hereby described with reference to the exemplary embodiments as above, it should be understood that the present invention may be variously modified and changed within a scope without departing from the spirit and the area of the present invention, and thus that such modifications and changes are within the scope of the present invention.
The present invention relates to a prefabricated wall for interior and its construction method, and minimizes use of screws to facilitate an installation/disassembly and reassembly of a wall and allows a small number of personnel to perform the installation or disassembly work at once, and reduces labor costs, and can shorten a construction period, and is useful for a manufacturing field of a prefabricated wall.
