Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a building wall,

More particularly, the present invention relates to a method of constructing an inner wall for building and a wall for building, and more particularly, to a method of constructing a construction inner wall and an inner wall for building, And more particularly, to a method of constructing a building wall and a building wall by improving the appearance of the building by providing a sufficient space for wiring and wiring of electric wires and communication lines inside the wall.

Generally, interior walls such as non-proof walls or partition walls are installed in various buildings such as buildings, apartments, general houses and factories. Such an inner wall separates an interior space to separate a generation and a generation, and performs a heat insulation / soundproof function.

Therefore, the existing construction wall is constructed by applying the dry wall method. This drywall method is advantageous in that it is lightweight and can be applied without imposing a burden on the building, unlike the wet type construction in which blocks or bricks are piled up. At this time, the dry wall construction method should have the insulation property and the sound insulation and have the structural strength. For this purpose, the structure of the inner wall constructed by the conventional drywall method is a structure in which a stator constituting a skeleton is installed uprightly, a non-combustible outer plate material as a gypsum board is disposed on both sides of the stud, and a heat insulating material And the stud and the outer plate are fastened and assembled using a joint in a state of being inserted and installed.

However, in the conventional drywall structure of the related art, since the single-layer heat insulation mat is disposed inside the outer plate, the sound insulation performance is lowered. When the outer plate material made of the gypsum board is scratched in a wet state, There is a problem in that it is structurally weak.

In order to solve the above problem, Korean Utility Model Registration No. 0163845 discloses a frame for a plurality of panels to be assembled and installed. The partition frame disclosed in the above-mentioned line registration design is formed such that first narrow coupling portions are opened in opposite directions to each other, and second wide coupling portions are opened between the front and rear sides and the front and rear face plates in opposite directions A first engaging portion having a narrow width is formed to be opened inward and a second engaging portion is formed at an outer side of the vertical engaging portion to engage with a sealing agent, And a horizontal member having a wide third coupling portion between the front and rear sides and the front and rear face plates.

However, the frame structure for the line registration design is complicated in its own structure of the vertical member and the horizontal member, so that it is difficult to form and manufacture it, and the installation work is troublesome. In particular, the vertical member is manufactured through a complicated bending process and a molding process in a multistage manner in order to form the first and second engaging portions.

In order to solve the above-mentioned problem, Korean Patent Registration No. 683633 discloses a method for constructing a building wall and a method for constructing the wall by minimizing the width of the wall itself, . Such a patent registration No. 683633 includes a first step of fixing a lower runner to a floor surface inside a building; A second step of fixing an upper runner to a ceiling inside the building so as to correspond to the lower runner; A third step of installing a first extrusion molded cement panel on the upper / lower runner and fixing the extrusion molded cement panel by an angle; A fourth step of adhering and fixing a heat insulating material to the inner surface of the first extrusion-molded cement panel; And a fifth step of installing a second extrusion-molded cement panel on the upper / lower runner and fixing the extrusion-molded cement panel by an angle.

However, the above-mentioned patent registration No. 683633 discloses that the lower runner and the upper runner are essentially arranged on the bottom surface and the ceiling in order to vertically install the first and second extrusion-molded cement panels vertically spaced on the ceiling and bottom surface of the building, So that the installation work requires a lot of processes, which results in a problem that the working efficiency is lowered. This problem also occurs in the dismantling of the wall.

On the other hand, in Korean Patent Application Publication No. 10 (2012) -29285 (published on Mar. 26, 2012), it is known that an extrusion molded cement panel is fixed to a floor surface and a ceiling by an elastic clip including a fixing piece and an insert, A method for constructing an inner wall and a method for constructing the inner wall are proposed. Such a Korean patent publication No. 10-2012-29285 discloses a method of inserting an insert of the elastic clip into each hollow so that the fixing piece of the elastic clip is positioned on the outer surface of the first extrusion- step; A second step of vertically installing a first extrusion-molded cement panel by fixing a fixing piece of an elastic clip provided on the first extrusion-molded cement panel to a ceiling and a bottom surface of a building; A third step of installing a heat insulating material on the inner surface of the first extrusion-molded cement panel; And a fixing piece of an elastic clip provided on the second extrusion-molded cement panel so as to be in contact with a heat insulating material provided on the first extrusion-molded cement panel is fixed to a ceiling and a bottom surface of the inside of the building to form a second extrusion-molded cement panel. Step < / RTI >

However, in the above-mentioned Korean Patent No. 10-2012-29285 and Patent No. 683633, the heat-insulating material is adhered and fixed to the inner surface of the first extrusion-molded cement panel, so that the inside of the inner wall, There is a problem in that it is not possible to provide a separate space between the extrusion-molded cement panels so that various electric wires and communication lines existing in the inside of the building can be wired in the inner wall, and various pipes can not be installed in the inner wall. If the electric wire, the communication line, or the various pipes are installed on the outer surface of the inner wall, such a problem may be hindered as well as the electric wires and communication lines or pipes exposed to the outside may be easily damaged.

Particularly, the conventional inner wall bodies using the extrusion-molded cement panel as shown in the above-mentioned Patent Registration Nos. 683633 and 10-2012-29285, are cut through the hollow portion of the extrusion-molded cement panel for wire entry or piping The method of re-finishing the incision after pulling in the wire or installing the piping has adopted the problem that the dust is generated in the incision of the extrusion molded cement panel and the construction period is increased due to the incision work and the rework of the incision site There is a problem that the quality of the inner wall is deteriorated due to the troubles of the maintenance work and the exposure of the re-finishing site.

Accordingly, the present invention has been made to solve the conventional problems of the conventional interior wall structure,
