Description

[Technical Field]

[0001] The present invention relates to a method for constructing the interior walls of a modular house, and more particularly to a method for constructing the interior walls of a modular house, which can improve workability, shorten the construction period, and reduce construction costs by continuously applying insulation material for heat insulation and wallpapering over the entire surface of the interior walls in a single process. [Background technology]

[0002] A container house is a type of prefabricated temporary building that can be constructed in a factory and then installed wherever desired. This container house differs from the temporary buildings that were previously constructed using sandwich panels, and has the advantage of being quicker to set up than conventional buildings, and being able to be moved to another location after use.

[0003] These container houses have traditionally been used mainly as offices and dormitories at construction sites, but they are increasingly being used as temporary accommodations at tourist sites, as dormitories for residents who need to live there temporarily until construction is completed, and as school dormitories.

[0004] Therefore, recently, container houses have been produced with exteriors and interiors that are as luxurious as ordinary residential buildings, and these container houses are widely used because they are comparable to ordinary accommodation facilities due to their differentiated designs from the conventional uniform container houses.

[0005] When constructing the interior walls of such a container house, it is common to first install insulation material such as polystyrene foam inside the frame of the container house, and then apply wallpaper on top of the insulation material.

[0006] In this case, the construction period is long because the installation of the insulation material and the wallpapering must be carried out separately, and the construction costs are high because separate insulation installers and wallpaperers must be employed.

[0007] In particular, the recent coronavirus outbreak has led to an explosive increase in demand for container houses as clinics and accommodations for isolating and treating coronavirus infected individuals, but the above-mentioned conventional technologies have had the problem of being unable to meet this explosive increase in demand. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a method for constructing interior walls of a modular house that can improve workability and shorten the construction period.

[0009] It is yet another object of the present invention to provide a method for constructing interior walls of a modular house, which can minimize construction costs and reduce manufacturing costs of the modular house. [Means for solving the problem]

[0010] In one aspect of the present invention to achieve the above-mentioned object, the present invention relates to a method for constructing an interior wall of a modular house having a rectangular parallelepiped appearance, comprising: (A) a step of installing a temporary interior wall inside a container frame; (B) a step of filling an insulating foam resin between the wall of the container frame and the temporary interior wall and then curing the filling; and (C) a step of moving the temporary interior wall along the wall of the container frame and then repeatedly performing steps (A) and (B).

[0011] In the method for constructing the interior walls of a modular house according to one embodiment of the present invention, the container framework may be a standardized container box with openings for access and lighting, and may include a square bottom; a square ceiling facing the bottom; and side walls vertically connected between the bottom and ceiling.

[0012] In addition, the temporary inner wall may include an upper plate that is installed at a predetermined distance from the ceiling and side wall when temporarily installed inside the container frame, but is formed to be shorter than the width of the ceiling by a predetermined length; a pair of side plates that are formed downward from the end of the upper plate to face the side wall in the longitudinal direction, but are formed to be shorter than the height of the side wall in the longitudinal direction by a predetermined length; and a finishing plate that finishes one side end of a structure consisting of the upper plate and the pair of side plates.

[0013] Each of the top plate, side plate and finish plate may include a plurality of rectangular connecting pieces, which may be foldably connected by a pivot shaft installed between adjacent connecting pieces.

[0014] In addition, each of the upper plate, the side plate and the finishing plate may be configured to include a plurality of rectangular connecting pieces, and the plurality of rectangular connecting pieces may have a fitting protrusion formed on one side in the longitudinal direction and a fitting groove formed on the other side, so that the plurality of rectangular connecting pieces are fitted together and connected to each other.

[0015] The step (A) may include: (A1) forming a temporary inner wall in an installation form using the connecting pieces inside the container frame; (A2) adhering wallpaper to the outer surface of the temporary inner wall; and (A3) moving the temporary inner wall to an installation position.

[0016] The top plate, side plate and finish plate may each be formed with suction holes for adsorbing wallpaper.

[0017] Step (A2) may include: (A21) placing wallpaper on the top board, side boards, and finish board; (A22) connecting an air pump to the suction holes and then suctioning the wallpaper onto the top board, side boards, and finish board; (A23) maintaining the suction state while filling the insulating foam resin in step (B); and (A24) stopping the operation of the air pump after step (B).

[0018] In addition, the wallpaper may be maintained in an adsorbed state during the filling of the insulating foam resin in step (B); and although the operation of the air pump is stopped after the insulating foam resin has cured, the negative pressure of the air pump may be gradually varied to adjust to a positive pressure corresponding to the expansion pressure of the insulating foam resin during the curing of the insulating foam resin in step (B).

[0019] Step (B) may include: (B1) positioning a pipe for filling the insulating foam resin at one end between the wall and the ceiling of the container frame and the wallpaper; (B2) moving the pipe for filling the insulating foam resin from one end to the other end to fill the insulating foam resin between the wall and the ceiling of the container frame and the wallpaper; and (B3) allowing the insulating foam resin to cure for a predetermined period of time after filling is complete.

[0020] The heat insulating foam resin may be a composition containing 20 to 50% by weight of a phenolic resin, 1 to 10% by weight of a surfactant, 10 to 40% by weight of a melamine compound, 0.1 to 5% by weight of a foaming accelerator, 20 to 40% by weight of a flame retardant, and 10 to 20% by weight of a solvent.

[0021] The flame retardant may be one containing a halogen-based flame retardant.

[0022] The upper plate and the side plate may be installed at intervals of 5 cm to 15 cm from the ceiling portion and the side wall portion in the longitudinal direction, respectively.

[0023] The step (A) may further include a step of installing a filling prevention frame, which is formed in a shape corresponding to the outer edge of the opening and prevents the insulating foam resin from being filled into the opening, before moving the temporary inner wall to the construction position in the step (A3).

[0024] In addition, when the filling prevention frame is installed, a strip of wallpaper may be attached to the outer edge surface of the filling prevention frame to prevent contact between the filling prevention frame and the insulating foam resin, making it easier to separate the filling prevention frame, and to finish the edge of the opening.

[0025] The front surface of the fill prevention frame may be formed with a guide groove for cutting the wallpaper. [Effects of the Invention]

[0026] The method for constructing the interior walls of a modular house according to the present invention involves installing a temporary interior wall adjacent to the inside of a container frame wall, attaching wallpaper to the temporary interior wall, and then filling the space between the container frame wall and the temporary interior wall with insulating foam resin and curing it. This allows the installation of insulating material for insulating the interior walls and the application of wallpaper to be carried out simultaneously, thereby improving workability and shortening the construction period.

[0027] In addition, unlike the prior art, which required separate technicians for insulation work and wallpapering, the present invention has the effect of minimizing construction costs by having the same technician perform both the insulation work and wallpapering work.

[0028] Furthermore, the present invention has the effect of realizing a fast and high-quality finished interior wall by using a folding or assembly type temporary wall and wallpaper that is attached by air pressure.

[0029] Furthermore, according to the present invention, the construction period can be significantly shortened, which has the effect of proactively responding to the demand for container houses that are urgently needed, such as lodgings for isolating and accommodating people infected with the coronavirus.

[0031] According to a preferred embodiment of the present invention, there is provided a method for constructing an interior wall of a modular house having a rectangular parallelepiped appearance, the method comprising: (A) installing a temporary interior wall inside a container frame; (B) filling a space between the wall of the container frame and the temporary interior wall with a heat insulating foam resin and then curing the space; and (C) moving the temporary interior wall along the wall of the container frame, and then repeatedly performing steps (A) and (B). The container frame is a standardized container box having openings for access and lighting, but has a square bottom and a rectangular ceiling portion facing the bottom portion; and side wall portions vertically connected between the bottom portion and the ceiling portion; and the temporary inner wall comprises a top plate which is installed at a predetermined distance from the ceiling portion and the side wall portions when temporarily installed inside the container frame, but which is formed to be shorter than the width of the ceiling portion by a predetermined length; a pair of side plates which are formed downward from the end of the top plate facing the side wall portions in the longitudinal direction, but which are formed to be shorter than the height of the side wall portions in the longitudinal direction by a predetermined length; and a finishing plate which finishes one side end of the structure consisting of the top plate and the pair of side plates.

[0032] The present invention can be modified in various ways and can have various embodiments, and therefore, specific examples will be illustrated in the drawings and described in detail. However, this is not intended to limit the present invention to the specific embodiments, and it should be understood that the present invention includes all modifications, equivalents, and alternatives within the spirit and technical scope of the present invention. In describing the present invention, if it is determined that detailed description of related publicly known technology may obscure the gist of the present invention, such detailed description will be omitted.

[0033] Terms such as "first," "second," etc. may be used to describe various components, but the components should not be limited by these terms. These terms are used only to distinguish one component from another.

[0034] The terms used in this application are merely used to describe specific embodiments and are not intended to limit the present invention. The singular expressions include the plural expressions unless the context clearly dictates otherwise. In this application, the terms "comprise" or "have" are intended to specify the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should be understood not to preclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0035] The present invention relates to a method for constructing an interior wall of a modular house, which can improve workability, shorten the construction period, and reduce construction costs by simultaneously performing the installation of insulation materials for heat insulation and the application of wallpaper when constructing the interior wall of a modular house.

[0036] Hereinafter, the method for constructing the interior walls of the modular house of the present invention will be described in more detail with reference to preferred embodiments and the accompanying drawings. In this regard, Fig. 1 is a block diagram illustrating the steps of the method for constructing the interior walls of the modular house of the present invention, and Fig. 2 is a perspective view of the modular house used in the construction method of the present invention.

[0037] First, referring to FIGS. 1 and 2, the method for constructing the interior walls of a modular house according to the present invention can be broadly composed of: (A) installing a temporary interior wall inside a container frame; (B) filling a space between the wall of the container frame and the temporary interior wall with a heat insulating foam resin and then curing the space; and (C) moving the temporary interior wall along the wall of the container frame, and then repeatedly performing steps (A) and (B).

[0038] The modular house according to the present invention is constructed based on a container frame 100 having a rectangular parallelepiped shape, and the container frame 100 can be manufactured in a standardized form in a factory and transported to a site by a large truck or the like for installation.

[0039] The container frame 100 is provided with an opening 40 for access and lighting, and a space for installing various facilities for living or working can be provided inside the container frame 100.

[0040] More specifically, the container frame 100 may include a square bottom 10, a square ceiling 20 facing the bottom 10, and side walls 30A and 30B vertically connected between the bottom 10 and the ceiling 20. In addition, openings 40 for installing doors, windows, etc. may be formed in the side walls 30A and 30B.

[0041] The container frame 100 can be firmly fixed to the ground by a number of piles (not shown) that penetrate the corners and are driven into the ground. In addition, the modular house of the present invention can include not only residential houses but also cargo containers, for example.

[0042] Meanwhile, FIG. 3 is a perspective view schematically illustrating a container frame 100 and a temporary inner wall 200 to explain the construction method of the interior wall of the modular house according to the present invention, FIG. 4 is a cross-sectional view illustrating the container frame 100 and the temporary inner wall 200, and FIG. 5 is a detailed perspective view of the temporary inner wall 200.

[0043] 3 to 5, when the temporary inner wall 200 is temporarily installed inside the container framework 100, it can be installed at a predetermined distance from the ceiling 20 and the side walls 30A and 30B.

[0044] For this purpose, the temporary inner wall 200 may include an upper plate 210 formed to be shorter by a predetermined length than the width of the ceiling portion 20 of the container framework 100, a pair of side plates 220 formed downward from an end of the upper plate 210 facing the side wall portion 30A in the longitudinal direction of the container framework 100, but formed to be shorter by a predetermined length than the height of the side wall portion 30A in the longitudinal direction of the container framework 100, and a finishing plate 230 for finishing one side end of the structure formed by the upper plate 210 and the pair of side plates 220.

[0045] As a result, when the top plate 210 and the pair of side plates 220 are assembled, the top plate 210 and the pair of side plates 220 can be installed inside the container frame 100 at a predetermined distance from the ceiling portion 20 and the side wall portions 30A, 30B of the container frame 100.

[0046] On the other hand, since the temporary inner wall 200 must be installed at a predetermined distance from the ceiling 20 and side wall portions 30A, 30B of the container framework 100, there is a risk that the size of the temporary inner wall 200 will be so large after installation that it will not be able to pass through the entrance and exit of the container framework 100.

[0047] Therefore, according to the present invention, each of the top plate 210, side plate 220 and finish plate 230 is configured to include a plurality of rectangular connecting pieces (A), and the plurality of rectangular connecting pieces (A) can be configured to be foldably connected by a pivot 240 installed between adjacent connecting pieces (A).

[0048] Thus, the temporary inner wall 200 passes through the entrance of the container framework 100 with each connecting piece (A) folded, and then is unfolded and installed inside the container framework 100.

[0049] 6 is a perspective view of another embodiment of the connecting piece A. Referring to FIG. 6, the rectangular connecting pieces A may have a fitting protrusion 250 formed on one side in the longitudinal direction and a fitting groove 260 formed on the other side, so that the rectangular connecting pieces A can be fitted together and connected.

[0050] According to this embodiment, the connecting pieces (A) are stored and transported in disassembled states, and the temporary inner wall 200 is installed by transporting the connecting pieces (A) into the container frame 100 and assembling them.

[0051] Hereinafter, the method for constructing the inner wall of the modular house of the present invention will be described step by step in accordance with the construction sequence, again with reference to FIG.

[0052] 2. A step of forming a temporary inner wall 200 in a construction form by using the connecting pieces (A) inside the container frame 100.

[0053] First, as described above, the folded connecting piece (A) or each separated connecting piece (A) is carried into the interior of the container frame 100, and the temporary inner wall 200 is installed so as to be spaced a predetermined distance from the ceiling portion 20 and side wall portions 30A, 30B of the container frame 100.

[0054] A step of adhering wallpaper to the outer surface of the temporary inner wall 200

[0055] Next, wallpaper 300 is attached to the upper plate 210, side plate 220 and finish plate 230 of the temporary interior wall 200. For this purpose, suction holes 270 for adsorbing the wallpaper 300 are formed in the upper plate 210, side plate 220 and finish plate 230 as shown in FIG. 7.

[0056] To explain this in more detail, first, the wallpaper 300 is placed on the top plate 210, side plate 220, and finish plate 230. Next, an air pump (not shown) is connected to the suction holes 270, and then the wallpaper 300 is sucked onto the top plate 210, side plate 220, and finish plate 230.

[0057] That is, when the air pump is operated, a negative pressure is maintained through the suction holes 270, so that the wallpaper 300 is tightly attached to the top plate 210, the side plate 220 and the finishing plate 230.

[0058] Filling and curing stage of thermal insulation foam resin 400

[0059] Once the wallpaper 300 has been tightly attached to the temporary inner wall 200 as described above, a pipe for filling the insulating foam resin (not shown) is positioned at one end between the wallpaper 300 and the side wall portions 30A, 30B and ceiling portion 20 of the container frame 100, and then the insulating foam resin filling pipe is moved from one end to the other end to fill the insulating foam resin 400 between the wallpaper 300 and the side wall portions 30A, 30B and ceiling portion 20 of the container frame 100.

[0060] In this case, the adsorption state is maintained while the insulating foam resin 400 is being filled, so that the wallpaper 300 is kept in close contact with the temporary inner wall 200 .

[0061] On the other hand, during the curing stage of the insulating foam resin 400, the insulating foam resin 400 expands and the expansion pressure acts on the wallpaper 300, which may cause the part of the wallpaper 300 where the suction hole 270 is formed to bulge outward.

[0062] Therefore, according to the present invention, during the curing of the insulating foam resin 400, the negative pressure of the air pump is gradually varied to adjust it to a positive pressure corresponding to the expansion pressure of the insulating foam resin 400, thereby solving this problem.

[0063] In the present invention, the heat insulating foam resin 400 may be composed of a composition containing 20 to 50% by weight of phenolic resin, 1 to 10% by weight of surfactant, 10 to 40% by weight of melamine compound, 0.1 to 5% by weight of foaming accelerator, 20 to 40% by weight of flame retardant, and 10 to 20% by weight of solvent.

[0064] Here, the flame retardant may include, but is not limited to, a halogen-based flame retardant, which may include a bromine (Br)-based flame retardant or a fluorine (F)-based flame retardant.

[0065] The phenolic resin may have a viscosity of 4,000 to 25,000 cps at a temperature of 25° C. and a moisture content of 2 to 12%. The surfactant may be a nonionic surfactant or a silicone surfactant.

[0066] In the present invention, the temporary inner wall 200 is preferably installed at intervals of 5 cm to 15 cm from the side walls 30A, 30B and the ceiling 20 of the container frame 100. If the temporary inner wall 200 is spaced less than 5 cm from the side walls 30A, 30B and the ceiling 20 of the container frame 100, the insulating effect may be insignificant, and if it is spaced more than 15 cm, it may result in over-construction and a reduction in the internal space.

[0067] a step of moving the temporary inner wall 200 along the wall of the container frame 100 and then repeating the above-mentioned process;

[0068] After the curing of the insulating foam resin 400 is completed as described above, the temporary inner wall 200 is moved along the longitudinal side wall portion 30A of the container frame 100, the wallpaper 300 is adhered, and then the steps of filling the insulating foam resin 400 and curing it are carried out in the same manner as described above.

[0069] Installing the filling prevention frame

[0070] On the other hand, as mentioned above, openings 40 will be formed in the container frame 100 for entry and exit, lighting, ventilation, etc., but it is necessary to prevent such openings 40 from being filled with insulating foam resin 400.

[0071] Therefore, according to the present invention, before the temporary inner wall 200 is moved to the construction position, the filling prevention frame 500 formed in a shape corresponding to the outer edge of the opening 40 is installed in line with the outer edge of the opening 40, as shown in FIG.

[0072] At this time, a strip-shaped wallpaper 600 is attached to the outer edges 510 to 540 of the filling prevention frame 500 to prevent contact between the filling prevention frame 500 and the insulating foam resin 400, thereby facilitating separation of the filling prevention frame 500 and finishing the edge portion of the opening 40.

[0073] In addition, the wallpaper 300 attached to the side panel 220 of the temporary interior wall 200 by suction is attached to the front surface of the fill-up prevention frame 500, and although it is necessary to cut it, it can be difficult to clearly grasp the boundary line. Therefore, according to the present invention, a guide groove 550 for cutting the wallpaper 300 is formed on the front surface of the fill-up prevention frame 500, thereby making it easier to cut the wallpaper 300.

[0074] Although the preferred embodiments of the present invention have been described above, a person having ordinary skill in the art may modify and change the present invention in various ways by adding, changing, deleting or adding components within the scope of the concept of the present invention as set forth in the claims, and this also falls within the scope of the present invention.

[0075] For example, each component described as a single unit may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form. The scope of the present invention is defined by the claims that follow rather than the above detailed description, and all modifications and variations that come within the meaning and scope of the claims and their equivalents are also included within the scope of the present invention. [Industrial Applicability]

[0076] The present invention relates to a method for constructing the interior walls of a modular house, which allows for the simultaneous application of insulation materials and wallpapering. By simultaneously applying insulation materials and wallpapering, the present invention has the effect of improving workability, shortening the construction period, and reducing construction costs.
