Description

[Technical field]

[0001] The present invention relates to a method for constructing an interior wall of a modular house, and more particularly, 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 continuously applying insulation material for heat insulation and wallpapering over the entire surface of the interior wall in a single process. [Background technology]

[0002] A container house is a type of prefabricated temporary building that can be built in a factory and then installed wherever desired. This container house is different from temporary buildings that were previously built using sandwich panels, and has the advantage that it can be set up quickly compared to conventional buildings, and can be moved to another location after use is completed.

[0003] These container houses were mainly used as offices and dormitories at construction sites in the past, but are increasingly being used as temporary accommodation facilities 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. 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 framework 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 insulation material installation and wallpapering must be carried out separately, and the construction costs are high because separate insulation material installers and wallpaper installers 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 to isolate and treat patients infected with the coronavirus, but the above-mentioned conventional technologies have had problems in 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 problems of the prior art as described above, and an object of the present invention is to provide a method for constructing an interior wall of a modular house, which can improve workability and shorten the construction period.

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

[0010] One aspect of the present invention for achieving the above-mentioned object relates to a method for constructing an interior wall of a modular house having an external appearance of a rectangular parallelepiped shape, comprising: (A) a step of installing a temporary inner wall inside a container framework; (B) a step of filling a space between the wall of the container framework and the temporary inner wall with an insulating foamed resin and then curing the space; and (C) a step of moving the temporary inner wall along the wall of the container framework and then repeatedly performing steps (A) to (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 constructed by providing a standardized container box with openings for access and lighting, and may include a rectangular bottom; a rectangular ceiling facing the bottom; and side walls vertically connected between the bottom and the ceiling.

[0012] In addition, the temporary inner wall may include an upper plate which is installed at a predetermined distance from the ceiling and side wall when temporarily installed inside the container frame, but which is formed to be shorter than the width of the ceiling by a predetermined length; a pair of side plates which are formed downward from an end of the upper plate facing the side wall in the longitudinal direction, but which are formed to be shorter than the height of the side wall in the longitudinal direction by a predetermined length; and a finishing plate which 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 finishing 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 an engaging protrusion formed on one side in the longitudinal direction and an engaging groove formed on the other side, so that the plurality of rectangular connecting pieces are engaged with each other to be connected.

[0015] The step (A) may include the steps of: (A1) forming a temporary inner wall in an installation form inside a container frame using the connecting pieces; (A2) attaching wallpaper to an 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] The step (A2) may include: (A21) placing wallpaper on the top board, side board, and finish board; (A22) connecting an air pump to the suction holes and then suctioning the wallpaper onto the top board, side board, and finish board; (A23) maintaining the suction state while filling the insulating foam resin in the step (B); and (A24) stopping the operation of the air pump after the step (B).

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

[0019] The step (B) may include: (B1) positioning a pipe for filling the insulating foam resin at one end between the side wall and the ceiling of the container frame and the wallpaper; (B2) filling the insulating foam resin between the side wall and the ceiling of the container frame and the wallpaper while moving the pipe for filling the insulating foam resin from the one end to the other end; and (B3) curing the insulating foam resin for a predetermined time after filling is completed.

[0020] The heat insulating foamable 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 include 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 an outer edge of the opening and prevents the insulating foam resin from being filled into the opening, before moving the construction position of the temporary inner wall in the step (A3).

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

[0025] The fill-up prevention frame may have a guide groove formed on a front surface thereof for cutting the wallpaper. Effect 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 construction of insulating materials for insulating the interior walls and the overlaying of wallpaper to be carried out simultaneously, improving workability and shortening the construction period.

[0027] In addition, unlike the conventional technology 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 insulation work and wallpapering work.

[0028] In addition, the present invention has an effect of realizing an interior wall that is quickly and well-finished 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 required, such as lodgings for isolating and housing people infected with the coronavirus.

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

[0032] The present invention can be modified in various ways and can have various embodiments, and therefore, a specific embodiment will be described in detail with reference to the drawings. However, this is not intended to limit the present invention to a specific embodiment, 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 a detailed description of related known technology may obscure the gist of the present invention, the 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 the terms. The terms are used only to distinguish one component from another.

[0034] The terms used in this application are merely used to describe certain embodiments and are not intended to limit the present invention. A singular expression includes a plural expression unless the context clearly indicates otherwise. In this application, the terms "include" 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 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 inner wall of a modular house, which can improve workability, shorten the construction period, and reduce the construction cost by simultaneously carrying out the construction of a heat insulating material for heat insulation and the topcoat of wallpaper.

[0036] Hereinafter, the method for constructing the inner wall 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 inner wall 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 an inner wall of a modular house according to the present invention can be roughly composed of: (A) a step of installing a temporary inner wall inside a container framework; (B) a step of filling a space between the wall of the container framework and the temporary inner wall with a heat insulating foam resin and then curing the space; and (C) a step of moving the temporary inner wall along the wall of the container framework and then repeatedly carrying out steps (A) and (B).

[0038] The modular house according to the present invention is constructed based on a container framework 100 having a rectangular parallelepiped shape, and the container framework 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 framework 100 is provided with an opening 40 for entering and exiting and for letting in light, and a space may be provided inside the framework 100 in which various facilities for living or working can be installed.

[0040] To explain this in more detail, the container framework 100 may include a rectangular bottom 10, a rectangular ceiling 20 facing the bottom 10, and side walls 30A, 30B vertically connected between the bottom 10 and the ceiling 20. Also, openings 40 for installing doors, windows, etc. may be formed in the side walls 30A, 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 illustrating a container framework 100 and a temporary inner wall 200 to explain a method of constructing the inner wall of the modular house according to the present invention, FIG. 4 is a cross-sectional view illustrating the container framework 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 portion 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 longitudinal side wall portion 30A of the container framework 100, but formed to be shorter by a predetermined length than the height of the longitudinal side wall portion 30A of the container framework 100, and a finishing plate 230 for finishing one side end of the structure consisting of 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] Meanwhile, since the temporary inner wall 200 must be installed at a certain distance from the ceiling 20 and the side walls 30A, 30B of the container framework 100, there is a risk that the size of the temporary inner wall 200 after installation will be so large 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, the side plate 220 and the finishing 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] Fig. 6 is a perspective view of another embodiment of the connecting piece A. Referring to Fig. 6, the rectangular connecting pieces A may be configured in such a way that a fitting protrusion 250 is formed on one side in the longitudinal direction and a fitting groove 260 is formed on the other side, so that the rectangular connecting pieces A are fitted together and connected to each other.

[0050] According to this embodiment, the connecting pieces (A) are stored and transported in a disassembled state, and the temporary inner wall 200 is installed by transporting the connecting pieces (A) inside 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 according to the construction sequence with reference to FIG.

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

[0053] First, as described above, the folded connecting piece (A) or each separated connecting piece (A) is brought 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 the side wall portions 30A, 30B of the container frame 100.

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

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

[0056] To explain this in more detail, first, the wallpaper 300 is placed on the top plate 210, the side plate 220 and the 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, the side plate 220 and the 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 onto the top plate 210 , the side plate 220 and the finishing plate 230 .

[0058] Filling and curing stage of insulating foam resin 400

[0059] Once the wallpaper 300 has been adhered 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 side wall portions 30A, 30B and the ceiling portion 20 of the container framework 100 and the wallpaper 300, and then the pipe for filling the insulating foam resin is moved from the one end to the other end to fill the insulating foam resin 400 between the side wall portions 30A, 30B and the ceiling portion 20 of the container framework 100 and the wallpaper 300.

[0060] In this case, the above-mentioned adhering 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, there is a concern that the insulating foam resin 400 will expand and the expansion pressure will act on the wallpaper 300, causing the portion of the wallpaper 300 where the suction hole 270 is formed to bulge outward and pop out.

[0062] Therefore, according to the present invention, during the curing of the insulating foam resin 400, the negative pressure of the air pump is sequentially changed to adjust it to a positive pressure corresponding to the expansion pressure of the insulating foam resin 400, thereby solving such problems.

[0063] In the present invention, the heat insulating foamed resin 400 may be composed of 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.

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

[0065] The phenol resin may have a viscosity of 4000 to 25000 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 an interval of 5 cm to 15 cm from the side walls 30A, 30B and the ceiling 20 of the container framework 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 framework 100, the heat 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] The temporary inner wall 200 is moved along the wall of the container frame 100, and the above-mentioned process is then repeated.

[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 framework 100, the wallpaper 300 is adhered, and then the steps of filling with the insulating foam resin 400 and curing are carried out in the same manner as described above.

[0069] Installing the fill prevention frame

[0070] On the other hand, as mentioned above, the container frame 100 will have openings 40 for entering and exiting, lighting, ventilation, etc., but it is necessary to prevent such openings 40 from being filled with the 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, which is 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 510-540 of the fill-prevention frame 500 to prevent contact between the fill-prevention frame 500 and the insulating foam resin 400, thereby facilitating separation of the fill-prevention frame 500 and to finish the edge portion of the opening 40.

[0073] In addition, the wallpaper 300, which is attached to the side plate 220 of the temporary inner wall 200 by suction, is attached to the front surface of the fill-in prevention frame 500, and although it is necessary to cut it, it may 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-in prevention frame 500, thereby making it easy to cut the wallpaper 300.

[0074] Although the above describes a preferred embodiment of the present invention, a person having ordinary knowledge in the relevant technical field may modify and change the present invention in various ways by adding, changing, deleting or adding elements without departing from the concept of the present invention described in the claims, and this also falls within the scope of the claims of the present invention.

[0075] For example, each component described as a single type 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 indicated by the claims below rather than the above detailed description, and all modifications and variations derived from the meaning and scope of the claims and their equivalents are also included in the scope of the present invention. [Industrial Applicability]
