Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to an assembled wall with an air duct passing through it and an installation method thereof. Background Art

[0002] The traditional house construction process usually starts with building a structural load-bearing frame, such as a steel structure or a cast cement frame structure, and then setting up internal partitions in the middle of the structural load-bearing frame as needed and for the specific purpose of the house, dividing the entire floor into functional rooms. At present, the production of internal partitions can be constructed on-site using light steel profiles and gypsum boards, or it can be constructed by installing and overlapping prefabricated wall panels. Among them, the on-site construction of light steel profiles and gypsum boards will result in a messy construction site, too much construction waste such as waste and scraps, and the constructed internal partitions cannot be disassembled and recycled, requiring a large amount of labor, with high labor costs and a long construction period. Therefore, the country vigorously advocates factory-based, rapid, and detachable prefabricated construction technology, that is, the use of prefabricated wall modules to overlap to form internal partitions.

[0003] At present, in the process of on-site overlapping and installation of wall modules to form inner partition walls, vents are often required to be set on the inner partition walls to avoid the air ducts of the central air-conditioning or fresh air system. However, when the size of the air duct is large and will pass through the overlapping profiles between the wall modules, and all the wall modules required for factory production are adopted, the shapes and sizes of the wall modules need to be produced differently, which greatly affects the mass production efficiency of the wall modules and is not conducive to the large-scale and rapid production of wall modules on the assembly line in the factory. In addition, in the process of on-site installation and construction of the wall modules, the deviation of the frame position at the construction site and the deviation of the construction process may cause the actual vent position to not match the air duct at the construction site. Summary of the invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In a first aspect, an embodiment of the present invention provides a prefabricated wall through which an air duct passes, referring to Figure 1 , Figure 2 and Figure 3 , including a main wall, a lower wall and a duct wall 300, the main wall and the lower wall are formed by overlapping and fixing a plurality of wall modules, the wall module 10 includes a profile frame and a first wall panel 100 located on two opposite sides of the profile frame, the profile frame includes at least two overlapping profiles 200 that can overlap each other, and the two overlapping profiles 200 are respectively located on two opposite sides of the wall module 10; wherein, the height of the overlapping profile 200 of the main wall and the height of the first wall panel 100 of the main wall are approximately equal to the distance between the building top plate and the building bottom plate; the height of the overlapping profile 200 at the edge of the lower wall is greater than the height of the overlapping profile 200 in the middle of the lower wall, and is approximately equal to the height of the overlapping profile 200 of the main wall, and the height of the first wall panel 100 of the lower wall is approximately equal to The height of the overlapping profile 200 in the middle of the lower wall; the duct wall 300 includes a second wall panel 310 and a supporting profile 320, the supporting profile 310 is arranged above the first wall panel 100 of the lower wall, and the two ends are respectively clamped with the two overlapping profiles 200 at the edge of the lower wall; the second wall panel 310 is fixed to the supporting profile 320 and the overlapping profile 200 at the edge of the lower wall, and is spliced ​​with the first wall panel 100 of the main wall and the first wall panel 100 of the lower wall, and the outer surface of the second wall panel 310 is flush with the outer surface of the first wall panel 100; the second wall panel 310 is provided with a vent adapted to the duct 330, the vent is located in the extension direction of at least one overlapping profile 200 in the middle of the lower wall, and the vent is used to avoid the duct 330.

[0033] The assembled wall through which the air duct crosses is provided in the embodiment of the present invention, referring to Figure 1 , Figure 2 and Figure 3The two ends of the support profile 320 are connected to the two overlapping profiles 200 at the edge of the lower wall, so that the wall around the air duct 330 above the multiple wall modules 10 of the lower wall forms a fixed whole, namely the air duct wall 300. The assembled wall formed by the overlap and fixation of the air duct wall 300 and the wall module 10 has a high impact resistance. In addition, the wall module 10 can be transported to the construction site after being processed in the factory; then, the wall module 10 can be directly overlapped and fixed at the construction site. When overlapped to the position of the air duct 330, the next wall module 10 is cut according to the size and position of the air duct 330 and then overlapped to obtain an assembled wall with a gap; finally, the support profile 320 and the second wall panel 310 with ventilation holes are installed at the above-mentioned gap. As can be seen from the above, the wall module 10 of the assembled wall with the air duct crossing the embodiment of the present invention does not need to preset the vents, and the position of the vents can be adjusted according to the actual situation, avoiding the problem that the position of the preset vents of the wall module 10 cannot meet the requirements of the actual construction site, and the structure of the wall module 10 is unified, and can be quickly produced on a large scale assembly line, simplifying the factory production process of the wall module 10, improving production efficiency, and reducing production costs. At the same time, the construction site is relatively clean, the construction process is convenient and fast, and the obtained assembled wall has a high impact strength.

[0034] It should be noted that the first wall panel 100 and the second wall panel 310 can be made of the same material, the overlapping profile 200 in the middle of the lower wall is the overlapping profile 200 between the multiple wall modules 10 of the lower wall, and the second wall panel 310 and the supporting profile 320 and the overlapping profile 200 at the edge of the lower wall are usually connected and fixed by screws through the second wall panel 310 and the supporting profile 200 and the overlapping profile 320, and the connection and fixing effect is good. It can be understood that when the size of the above-mentioned air duct 330 is small and only passes through one wall module 10, the air duct 330 will not conflict with the overlapping profile 200 of the wall module 10, and the wall can be directly formed by overlapping and fixing multiple wall modules 10, and then a vent for avoiding the air duct 330 is directly opened on the wall module 10 corresponding to the air duct 330, and the air duct 330 can be placed in the vent.

[0035] The number of wall modules 10 included in the main wall and the lower wall is not unique, and can be two, three or more, depending on the actual situation. The shape of the air duct 330 is also not unique, and the shape of the air duct 330 is usually a hollow rectangular parallelepiped. Figure 1 , Figure 2 and Figure 3 The main wall and the lower wall in the figure are both exemplified by two wall modules 10. Figure 1 , Figure 2 and Figure 3The air duct 330 in the figure is taken as an example of a rectangular air duct 330.

[0036] It is understandable that the above-mentioned prefabricated wall needs to be fixedly connected to the building roof and the building floor. In a feasible embodiment, the wall module 10 included in the above-mentioned prefabricated wall can be fixedly connected to the building roof and the building floor through fixings. The fixings are arranged between the overlapping profiles 200 that are spliced ​​with each other and do not protrude from the surface of the wall, which is convenient for subsequent decorative construction such as painting on the wall surface.

[0037] Among them, refer to Figure 1 , Figure 4 and Figure 8 The above-mentioned overlapping profile 200 includes a plurality of abutment plates 230 and a first side plate 210 and a second side plate 220 located on the same side of the abutment plates 230. The first side plate 210 and the second side plate 220 are respectively correspondingly fitted with the two first wall panels 100, and the two sides of the first wall panel 100 are flush with the side where the first side plate 210 and the second side plate 220 are connected to the abutment plates 230; the opposite ends of the plurality of abutment plates 230 are vertically connected in sequence to form a ladder, and one end of the ladder is vertically connected to the end of the first side plate 210. The first end of the overlapping profile 200 is connected to the end of the second side plate 220, and the other end is vertically connected to the end of the second side plate 220; the two overlapping profiles 200 are respectively arranged vertically on the opposite sides of the wall module 10, and the openings of the two overlapping profiles 200 are both facing the inner side of the wall module 10; wherein, the abutting plates 230 of the two overlapping profiles 200 can fit and abut against each other, and after the abutting plates 230 of the two overlapping profiles 200 abut against each other, the first side plate 210 of one overlapping profile 200 and the second side plate 220 of the other overlapping profile 200 are in the same plane. Based on this, the overlapping profile 200 can be integrally formed by a metal plate through a bending process, which is simple in process, high in overall strength, material saving, and low in cost.

[0038] In this way, the overlapping profiles 200 between multiple wall modules 10 can overlap and cooperate to form a wall with a larger area. In addition, through the overlapping cooperation of the overlapping profiles 200 between multiple wall modules 10, the overlapping profiles 200 on both sides of the middle wall module 10 are overlapped with the overlapping profiles 200 of the two adjacent wall modules 10, which can limit the movement of the wall module 10 in the direction perpendicular to the first wall panel 10, so that the wall formed by the overlapping of the wall modules 10 is more solid. At the same time, the overlapping profiles 200 on both sides of the wall module 10 are the same, avoiding the use of two different overlapping profiles 200 to achieve overlapping. The specifications of the overlapping profiles 200 are unified, which is convenient for factory production and has low cost. In addition, in the process of overlapping the above-mentioned multiple wall templates 10, the wall module 10 can be directly moved from one side of the wall along the direction perpendicular to the first wall panel 100 to the predetermined installation position. At this time, when the wall modules 10 located on both sides of the wall edge are installed, they can be moved from one side of the wall along a direction perpendicular to the first wall panel 100 to a predetermined installation position, so that the wall modules 10 can be used to accurately fill the entire area from the starting point of the wall to the end point of the wall, thereby avoiding the problem of leaving an installation gap at the end of the wall due to the use of convex and concave plug-in fittings, saving time and labor.

[0039] It should be noted that the method of fixed connection between the wall modules 10 is not unique. The two overlapping profiles 200 between two adjacent wall modules 10 can be connected and fixed by bonding, or by screws passing through the two overlapping profiles 200 between two adjacent wall modules 10 to achieve connection and fixation, which is not limited here.

[0040] In order to improve the strength of the wall module 10 and ensure that the overall structural strength of the wall formed by overlapping and fixing is high, Figure 1 and Figure 4 As shown, the profile frame further includes a connecting profile 400, which is perpendicular to the overlapping profile 200, and the end of the connecting profile 400 is embedded between the first side plate 210 and the second side plate 220 of the overlapping profile 200, and is fixed to the overlapping profile 200. The wall module 10 has high structural strength and strong shear and punching resistance. The connecting profile 400 can be an I-shaped, square or U-shaped opening profile.

[0041] In some embodiments, Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the plurality of abutment plates 230 include a first abutment plate 231, a second abutment plate 232, a third abutment plate 233, a fourth abutment plate 234 and a fifth abutment plate 235 which are vertically connected in sequence. The first abutment plate 231 is vertically connected to the first side plate 210, and the fifth abutment plate 235 is vertically connected to the second side plate 220. The width d1 of the first abutment plate 231 along the thickness direction of the first side plate 210 is approximately equal to the width d2 of the fifth abutment plate 235 along the thickness direction of the second side plate 220 (refer to Figure 6 ), the width d3 of the second abutting plate 232 along the thickness direction of the third abutting plate 233 is approximately equal to the width d4 of the fourth abutting plate 234 along the thickness direction of the third abutting plate 233 (refer to Figure 7 ). At this time, the number of bendings required to manufacture the overlap profile 200 is small, and the structure is relatively simple. In addition, when the above-mentioned fixing parts are used to connect the wall module 10 with the building roof or building floor, the fixing parts can be connected and fixed with the third abutment plate 233, and the third abutment plate 233 is located in the middle position of the overlap profile 200, and the connection stability between the fixing parts and the wall module 10 is relatively high; at the same time, the size of the third abutment plate 233 can be designed to be larger, and the contact area between the third abutment plate 233 and the fixing parts can be larger, and the connection stability is higher.

[0042] It is understandable that the two ends of the above-mentioned support profile 320 are respectively connected to the two overlapping profiles 200 at the edge of the lower wall in a manner that is not unique, and the support profile 320 can be an I-shaped, square or U-shaped opening profile. Figure 2 , Figure 3 and Fig.10 The supporting profile 320 includes a bottom plate 321 and side plates 322 located on both sides of the bottom plate 321. The side plates 322 are perpendicular to the bottom plate 321, and the distance between the outer surfaces of the two side plates 322 facing each other is approximately equal to the distance between the two inner surfaces of the first side plate 210 and the second side plate 220 facing each other. Both ends of the supporting profile 320 are clamped in the opening of the overlapping profile 200. In this case, the supporting profile 320 is clamped in the opening of the overlapping profile 200, and the overlapping profile 200 does not need to be separately designed with a clamping structure that matches the supporting profile 320, so the structure is simple and the cost is low.

[0043] Of course, the distance between the outer surfaces of the two side panels 322 of the supporting profile 320 can also be approximately equal to the distance between the first side panel 210 and the fourth abutting panel 234, and the two ends of the supporting profile 320 can also be clamped in the opening of the overlapping profile 200. The supporting profile 320 and the connecting profile 400 can have the same structure and only differ in size.

[0044] Further, such as Figure 2As shown, the number of the above-mentioned supporting profiles 320 is multiple, and the multiple supporting profiles 320 are staggered with the vents to avoid interference with the installation position of the air duct 330, so as to further improve the impact resistance of the air duct wall 300; at the same time, the multiple supporting profiles 320 are evenly distributed in the vertical direction, and the contact area between the second wall panel 310 and the supporting profiles 320 is large, which reduces the magnitude of the local force on the second wall panel 310, so that the force distribution between the second wall panel 310 and the supporting profiles 320 is uniform, and the risk of accidental deformation or even damage of the second wall panel 310 is reduced. Among them, the number of supporting profiles 320 can be adjusted accordingly according to the size of the air duct wall 300, for example, increased or decreased, to ensure that the air duct wall 300 can basically meet the preset impact resistance.

[0045] It is understandable that the upper edge and the lower edge of the duct wall 300 are stress concentration areas. In order to avoid local deformation of the upper edge and the lower edge of the second wall panel 310 of the duct wall 300, in a feasible embodiment, the plurality of support profiles 320 at least include a first support profile arranged at the bottom end of the duct wall 300 and a second support profile arranged at the top end of the duct wall 300, and the openings of the first support profile and the second support profile face downward. In this case, the top and the bottom ends of the duct wall 300 are both provided with support profiles 320, which can effectively avoid local deformation or damage of the upper edge and the lower edge of the second wall panel 310.

[0046] The bottom plate 321 of the second supporting profile is flush with the upper edge of the second wall panel 310, the contact area between the duct wall 300 and the building roof is large, and the erected wall is more stable. The side plate 322 of the first supporting profile away from the bottom plate 311 can protrude from the edge of the second wall panel 310, or can be flush with the edge of the second wall panel 310. In a feasible embodiment, refer to Figure 4 , the side plate 322 of the first supporting profile protrudes from the edge of the second wall panel 310 on one side away from the bottom plate 311, and the upper end of the abutting plate 230 of the overlapping profile 200 in the middle of the lower wall is located below the first side plate 210 and the second side plate 220 on both sides to form a mounting groove, and the first supporting profile is embedded in the mounting groove. Based on this, in addition to being connected with the overlapping profile 200 at the edge of the lower wall, the duct wall 300 also forms a snap connection with the overlapping profile 200 in the middle of the lower wall, and the connection between the duct wall 300 and the lower wall is more stable.

[0047] It should be noted that Fig. 9 The installation groove in the figure takes the upper end of the third abutment plate 233 located below the abutment plates on both sides thereof and the side plates as an example, that is, only the third abutment plate 233 is cut to form the installation groove, so that the first supporting profile is embedded in the installation groove formed by only cutting the third abutment plate 233.

[0048] In order to improve the thermal insulation and sound insulation performance of the wall, the space between the two first wall panels 100 and the space between the two second wall modules 310 are filled with thermal insulation and sound insulation materials, that is, the thermal insulation and sound insulation materials are filled in the space inside the entire wall. The thermal insulation and sound insulation layer can effectively prevent indoor energy loss and improve the energy saving effect of the building. At the same time, the thermal insulation and sound insulation layer is also used to reduce sound propagation, and the building has a good sound insulation effect, which helps users to rest.

[0049] In addition, when fixings are provided at the top and bottom areas of the two overlapping profiles 200 between each two adjacent wall modules 10, a gap is left in the middle part between the steps included in the two overlapping profiles 200. At this time, in order to ensure the thermal insulation and sound insulation performance of the wall, the gap is filled with a thermal insulation and sound insulation layer, that is, a gap is left between the steps included in the two overlapping profiles 200 between each two adjacent wall modules 10, and the thickness of the gap is equal to the thickness of the fixings, and the gap is filled with a thermal insulation and sound insulation layer, which is used for the thermal insulation of the house. Exemplarily, when air conditioning is used for cooling or heating indoors, the thermal insulation and sound insulation layer can effectively prevent indoor energy loss and improve the energy-saving effect of the building. The thermal insulation and sound insulation layer is also used to reduce sound propagation, and the building sound insulation effect is better, which helps users to rest. In addition, the thermal insulation and sound insulation layer is located between multiple wall modules 10, which does not affect the surface coating of the wall and the surface aesthetics of the wall.

[0050] It should be understood that due to the influence of temperature changes and earthquakes, additional stress will be generated inside the wall, which often causes cracks or even damage to the wall. The overlap between the multiple wall modules provided by the embodiment of the present invention, especially when there is a gap between two overlapping profiles, the gap between the two overlapping profiles of adjacent wall modules, to a certain extent reduces the influence of stress on the wall and reduces the risk of cracks or damage to the wall.

[0051] According to different usage scenarios and usage requirements, the profile frame can be made of one or more of metal materials, wood materials or wood-plastic materials. Each material has its own advantages and disadvantages, and is selected according to the environment and needs of use. For example, when designing residential walls, the walls have a long service life and high reliability requirements, and the profile frame is usually made of metal materials; wooden materials will not cause environmental pollution and can be used in scenarios with high environmental protection requirements; when it needs to be frequently disassembled or moved, and when high wear resistance is required, the profile frame can be made of wood-plastic materials. In addition to the above materials, the profile frame can also be made of other materials, which are not listed here one by one.

[0052] According to different usage scenarios and usage requirements, the above-mentioned fixings can be made of metal or polymer materials. Various materials have their own advantages and disadvantages, and they should be selected according to the environment and requirements. For example, when the above-mentioned profile frame is made of metal, the fixings are often made of metal, which has high strength and high reliability; when the above-mentioned profile frame is made of wood-plastic material, the fixings are usually made of polymer materials, which are light, easy to disassemble and move, and corrosion-resistant. In addition to the above-mentioned materials, the fixings can also be made of other materials, which are not listed here one by one.

[0053] Similarly, according to different usage scenarios and usage requirements, the first wall panel and the second wall panel are one or more combinations of gypsum board, calcium silicate board, glass magnesium board, glass wool board, ceramic board, fireproof board, sound-absorbing board, carbon felt board, cement board, medium-density fiberboard, European pine board, metal board, inorganic fiberboard, wood-plastic board or woodworking board. Each material has its own advantages and disadvantages, and the specific selection is based on the environment and needs of use. In addition to the above-mentioned materials, the first wall panel and the second wall panel can also be made of other materials, which are not listed here one by one.

[0054] In addition, according to different usage scenarios and usage requirements, the material of the above-mentioned thermal insulation and sound insulation layer can be one or more combinations of rock wool, granular wool, glass wool, phenolic foam board, polystyrene board, phenolic foam board, polyurethane board, foamed ceramic board, foamed glass board, perlite board, aluminum silicate fiber wool or ceramic fiber wool. In addition to the above-mentioned materials, the thermal insulation material layer can also be made of other materials, which are not listed here one by one.

[0055] In a second aspect, an embodiment of the present invention further provides an installation method for an assembled wall through which an air duct passes, which is used for the assembled wall through which the air duct passes, and the installation method includes: the wall module of the main wall is a first wall module, and the wall module at the edge of the lower wall is a second wall module, and the installation method includes: obtaining a plurality of first wall modules; cutting one side of two of the first wall modules having overlapping profiles toward the other side until only one overlapping profile remains on the other side, thereby obtaining two second wall modules and the cut thermal insulation and sound insulation materials and the cut four first wall panels; screwing the plurality of first wall modules together along the overlapping direction of the first wall modules using screws. The block and the two second wall modules are overlapped and fixed in sequence, so that the two second wall modules are located below the air duct, and an assembled wall with a gap is obtained; a plurality of supporting profiles are installed in sequence at the gap, so that the two ends of the supporting profile are inserted into the openings of the overlapping profiles on both sides of the gap; the two first wall panels cut off correspond to the vents cut off the air duct, and are installed in sequence on the outside of one side panel of the supporting profile by screws; the heat-insulating and sound-proofing materials cut off are filled around the air duct; the other two first wall panels cut off correspond to the vents cut off the air duct, and are installed in sequence on the outside of the other side panel of the supporting profile by screws, so as to obtain an assembled wall.

[0056] Specifically, the installation method of the assembled wall through which the air duct passes comprises the following steps:

[0057] Step S200, obtaining a plurality of first wall modules.

[0058] Step S210, cutting one side of two first wall modules with overlapping profiles to the other side until only one overlapping profile remains on the other side, thereby obtaining two second wall modules, the thermal insulation and sound insulation materials cut, and the four first wall panels cut. The vertical dimension of the cut is determined according to the position and size of the air duct. Usually, the vertical dimension of the cut is slightly lower than the bottom of the air duct, and the reduced height is greater than the width of the side plate of the supporting profile in the direction perpendicular to the thickness of the bottom plate, so as to ensure that at least one supporting profile can be set under the air duct. In a feasible embodiment, the third abutment plate of the overlapping profiles cut by the two second wall modules is cut so that the upper end of the third abutment plate is lower than the abutment plates and side plates on both sides thereof, so as to obtain the above-mentioned installation groove for embedding the supporting profile.

[0059] Step S220: Along the overlapping direction of the first wall module, multiple first wall modules and two second wall modules are overlapped and fixed in sequence using screws, so that the two second wall modules are located below the air duct, thereby obtaining an assembled wall with a gap.

[0060] Specifically, along the overlapping direction of the first wall module, multiple first wall modules are overlapped and fixed in sequence by screws, and then a second wall module is overlapped and fixed with the last first wall module by screws; finally, the remaining second wall module is overlapped and fixed with the previous second wall module by screws. The overlapped and fixed wall modules by screws are specifically that the abutment plates of the overlapped profiles between the wall modules are fitted and abutted against each other, and the screws pass through the wall panels and one overlapped profile and are fastened to another overlapped profile. Here, the wall module includes the first wall module and the second wall module, and the wall panel includes the first wall panel and the second wall panel. In addition, the overlapped and fixed between the second wall module and the first wall module is that the uncut overlapped profile of the second wall module is overlapped and fixed with the overlapped profile of the first wall module, and the overlapped and fixed between the two second wall modules is that the overlapped profiles of the two second wall modules after cutting are overlapped and fixed to each other, and a gap is formed between the two uncut overlapped profiles, and the air duct is located at the gap.

[0061] Step S230, multiple support profiles are sequentially installed at the gap, so that the two ends of the support profiles are inserted into the openings of the overlapping profiles on both sides of the gap. Specifically, the two ends of the multiple support profiles are sequentially inserted into the openings of the overlapping profiles on both sides from bottom to top, and the support profiles are perpendicular to the overlapping profiles on both sides. The positions of the support profiles and the air duct are staggered, and usually at least one support profile is arranged below the air duct.

[0062] Step S240, the two cut first wall panels are cut corresponding to the vents of the air duct, and are installed in sequence on the outer side of a side panel of the supporting profile using screws. Installing the cut first wall panels using screws includes connecting and fixing the first wall panels to the overlapping profile using screws and connecting and fixing the first wall panels to the supporting profile using screws.

[0063] Step S250, filling the cut thermal insulation and sound insulation material around the air duct.

[0064] Step S260, cutting vents from the other two first wall panels, and sequentially installing them on the outside of the other side panel of the supporting profile using screws to obtain an assembled wall. Installing the cut first wall panels using screws includes connecting and fixing the first wall panels to the overlapping profile using screws and connecting and fixing the first wall panels to the supporting profile using screws.

[0065] It can be understood that in the above step S220, before installing the last second wall module, a supporting profile that matches the installation groove of the second wall module can be installed first, and then one side of the overlapping profile cut from the last second wall module is moved horizontally to a preset position along the installed supporting profile for overlapping, and fixed with screws, and the other end of the supporting profile is inserted into the opening of the uncut overlapping profile of the last installed second wall module.

[0066] It should be noted that the overlapping profiles between each two adjacent wall modules are overlapped and fixed to each other, and the fixing effect can also be achieved by bonding. For example, an adhesive layer is provided between the overlapping profiles between the two adjacent wall modules. Of course, the fixing effect can also be achieved by providing a snap-on structure on the relative steps of the overlapping profiles between the two adjacent wall modules, which is not limited here.

[0067] In addition, when the lower wall module has three or more wall modules, the first wall module needs to be cut after step S210 to obtain a wall module located in the middle part of the lower wall. In step S220, the wall modules in the middle part of the lower wall need to be overlapped and fixed one by one between the two second wall modules.

[0068] In the installation method of the assembled wall provided by the embodiment of the present invention, the wall module does not need to preset the vents, and the position of the vents can be designed according to the actual situation, thereby avoiding the problem that the position of the preset vents of the wall module cannot meet the requirements of the actual construction site, and the structure of the wall module is unified, and large-scale assembly line rapid production can be carried out, simplifying the factory production process of the wall module, improving production efficiency, and reducing production costs. At the same time, the construction site is relatively clean, the construction process is convenient and fast, and the obtained assembled wall has a high impact strength.

[0069] The above step S200 specifically includes:

[0070] Step S201, placing two overlapping profiles in parallel, with the two openings of the two overlapping profiles arranged opposite to each other, and the two first side panels of the two overlapping profiles arranged on opposite sides.

[0071] Step S202, sequentially embedding two ends of a plurality of connecting profiles into the openings of two overlapping profiles respectively, and fixing the connecting profiles and the overlapping profiles to form a profile frame.

[0072] Step S203, filling the profile frame with thermal insulation and sound insulation materials.

[0073] Step S204: Use screws to install two first wall panels on both sides of the profile frame to obtain a first wall module.

[0074] By repeating the above steps S201 to S204, a plurality of first wall modules can be obtained.

[0075] In the description of this specification, specific features, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0076] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
