Description

Technical Field

[0001] This invention relates to the field of prefabricated wall technology, and more specifically, to a prefabricated wall structure with a heat insulation layer. Background Technology

[0002] Prefabricated walls are a type of building wall structure assembled in a factory or on a construction site using prefabricated components. Unlike traditional cast-in-place walls, the various parts of prefabricated walls (such as wall panels, insulation layers, and exterior finishes) are prefabricated in the factory and then quickly assembled after being transported to the construction site. This type of wall has the advantages of fast construction speed, stable weight, and high material utilization rate. At the same time, it can also reduce the environmental impact of construction, which is in line with the development trend of modern building industrialization.

[0003] Existing prefabricated wall structures lack flexible adjustment mechanisms to meet different insulation requirements, making it impossible to adjust the thickness of insulation materials according to actual conditions, resulting in poor insulation performance. In addition, the wall structure has poor adaptability to different climatic conditions, making it difficult to provide effective thermal management. Finally, while ensuring fire resistance, sound insulation, and heat insulation, it cannot meet the requirements of structural lightness, which brings excessive additional load to the building and has a significant impact on the safety of the building structure, thus affecting its widespread application in buildings. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated wall structure with a heat insulation layer to solve the problems mentioned in the background art, such as the inability to adjust the thickness of the insulation material, the difficulty in providing effective thermal management, and the lack of lightweight wall structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated wall structure with a heat insulation layer, comprising an exterior wall assembly, a heat insulation assembly, and an adjustment assembly. The exterior wall assembly includes a first exterior wall and a second exterior wall, each with slots at both ends. A first side wall panel and a second side wall panel are respectively inserted into the slots. The assembly also includes a bottom plate. The heat insulation assembly is disposed within a cavity formed by the first exterior wall, the second exterior wall, the first side wall panel, the second side wall panel, and the bottom plate. The bottom of the heat insulation assembly is slidably connected to the top of the bottom plate. The heat insulation assembly includes a first heat insulation plate and a second heat insulation plate, both of which are square grooves with their openings facing each other. The adjustment assembly includes a first adjustment component, a second adjustment component, and a third adjustment component. The bottom of the adjustment assembly is slidably connected to the top of the bottom plate.

[0006] Preferably, the first heat insulation board and the second heat insulation board are fixedly connected to the inner side of the second heat insulation board, the first heat insulation board is fixedly connected to the outer side of the first heat insulation board, the second heat insulation board is fixedly connected to the outer side of the third heat insulation board, the first outer wall is fixedly connected to the outer side of the first adjustment board, and the second outer wall is fixedly connected to the outer side of the third adjustment board.

[0007] Preferably, the outer side of the first outer wall is provided with reinforcing ribs and the bottom is provided with a fixing plate. Each fixing plate is provided with a first round through hole and positioning parts are provided at both ends of its bottom. The second outer wall is symmetrically arranged with the first outer wall. The bottom of the first outer wall is provided with a first air inlet, a first air outlet, a second air inlet and a second air outlet. The inner sides of the first heat insulation plate and the second heat insulation plate are provided with multiple reinforcing rib grooves at equal intervals.

[0008] Preferably, the first adjustment component consists of a plurality of first airbags, and each of the first airbags is connected to the other via an air duct.

[0009] Preferably, the third adjustment component consists of a plurality of third airbags, and each of the third airbags is connected to the other via an air duct.

[0010] Preferably, the second adjustment component consists of a plurality of second airbags, each of which is connected to the other via an air duct, and the second airbags are engaged within the reinforcing rib groove.

[0011] Preferably, the first airbag, the second airbag, and the third airbag are arranged linearly and equidistantly in the horizontal direction towards the center line, and the front and rear sides of the first airbag, the second airbag, and the third airbag are respectively provided with pleated structures.

[0012] Preferably, the second airbag is connected to the second inflation port and the second deflation port via an air guide tube, and the first airbag and the third airbag are connected via an air guide tube and connected to the first inflation port and the first deflation port via an air guide tube.

[0013] Preferably, the top of the base plate is provided with a positioning groove corresponding to the position of the positioning member, and the two sides of the base plate are provided with a plurality of second through holes, the second through holes being positioned corresponding to the first through holes, and the positioning member being inserted into the positioning groove.

[0014] Preferably, the positioning component has a limiting groove inside, and a positioning plate is provided vertically towards the center line inside the limiting groove. A telescopic spring is fixedly installed on both sides of the positioning plate, and a positioning rod that is slidably connected to the limiting groove is installed on the other end of the telescopic spring. A positioning hole that matches the positioning rod is provided on the inner wall of the positioning groove.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. In this invention, the first and second outer wall components are inserted into the positioning slots via positioning components. Without repeatedly adjusting the parallel angle between the first and second outer wall components and the perpendicular angle between the first and second outer wall components and the base plate, the initial installation of the first and second outer wall components and the base plate can be completed quickly. Then, the first and second side wall panels are respectively inserted into the slots at both ends of the first and second outer wall components, and finally locked by fastening bolts to achieve rapid positioning and installation of the outer wall components.

[0017] 2. The distance between the first and second heat insulation boards in this invention is adjusted in conjunction with the first, second, and third adjusting components. Furthermore, by adjusting the distance between the first and second heat insulation boards under different thermal insulation conditions, the thickness of the insulation agent filled between them changes, thereby achieving different thermal insulation requirements. The first, second, and third airbags are provided on both the inner and outer sides of the first and second heat insulation boards, giving the wall good sound insulation capabilities.

[0018] 2. The gas inside the airbag of this invention is an inert gas, which enhances the flame-retardant performance of the wall. The internal space of the heat insulation component is divided into multiple independent spaces by the second airbag, which strengthens the structural stability of the heat insulation component. In addition, in the event of a fire, its partition structure can slow down the spread of fire. Based on the heat insulation, sound insulation and lightweight characteristics of the airbag, compared with some traditional insulation materials (such as rock wool, polystyrene foam board, etc.), it is lighter while exhibiting better heat insulation capacity at the same thickness. It can effectively reduce the heat transfer coefficient of the building envelope, achieve better heat insulation and sound insulation effects, help reduce the exchange of heat between indoors and outdoors, reduce heat loss in winter and heat import in summer, achieve the purpose of energy saving and heat insulation without putting too much additional load on the building structure. While ensuring fire resistance, sound insulation and heat insulation, it can also meet the requirements of structural lightness, with minimal impact on the overall structural safety of the building, which is in line with the development concept of modern building environmental protection and energy saving.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] See attached document Figures 1 to 5A prefabricated wall structure with a heat insulation layer includes an exterior wall component 1, a heat insulation component 2, and an adjustment component 3. The exterior wall component 1 includes a first exterior wall 11 and a second exterior wall 12, each with slots at both ends. A first side wall panel 13 and a second side wall panel 14 are respectively inserted into the slots. It also includes a bottom plate 15. The outer side of the first exterior wall 11 is provided with reinforcing ribs, and a fixing plate 111 is provided at the bottom. The fixing plate 111 is provided with a first through hole 1111 and positioning points are provided at both ends of its bottom. Component 112, the second outer wall 12 is symmetrically arranged with the first outer wall 11, and will not be described in detail. The bottom of the first outer wall 11 has a first inflation port 113, a first deflation port 114, a second inflation port 115, and a second deflation port 116. The top of the base plate 15 is provided with a positioning groove 151 corresponding to the position of the positioning component 112. The two sides of the base plate 15 are provided with multiple second through holes 152, and the second through holes 152 are positioned corresponding to the positions of the first through holes 1111. The positioning component 112 is inserted into the positioning groove 151. The positioning component 112 has a limiting groove 1121 inside. A positioning plate 1122 is vertically positioned towards the center line inside the limiting groove 1121. Telescopic springs 1123 are fixedly installed on both sides of the positioning plate 1122. Positioning rods 1124, which are slidably connected to the limiting groove 1121, are respectively installed at the other end of the telescopic springs 1123. Positioning holes 1511, which match the positioning rods 1124, are opened on the inner wall of the positioning groove 151. During assembly, the first outer wall 11 and the second outer wall 12 pass through the positioning component. 112 is inserted into the positioning slot 151. Without repeatedly adjusting the parallel angle between the first outer wall 11 and the second outer wall 12 and the perpendicular angle between the first outer wall 11, the second outer wall 12 and the base plate 15, the initial installation of the first outer wall 11, the second outer wall 12 and the base plate 15 can be completed. Then, the first side wall panel 13 and the second side wall panel 14 are respectively inserted into the slots at both ends of the first outer wall 11 and the second outer wall 12. Finally, they are locked by fastening bolts to achieve quick positioning and installation of the outer wall component 1.

[0030] See attached document Figures 1 to 5The heat insulation component 2 is installed in the cavity formed by the first outer wall 11, the second outer wall 12, the first side wall panel 13, the second side wall panel 14, and the bottom plate 15. The bottom of the heat insulation component 2 is slidably connected to the top of the bottom plate 15. The heat insulation component 2 includes a first heat insulation plate 21 and a second heat insulation plate 22. Both the first heat insulation plate 21 and the second heat insulation plate 22 are square grooves with their openings facing each other. The adjustment component 3 includes a first adjustment member 31, a second adjustment member 32, and a third adjustment member 33. The bottom of the adjustment component 3 is slidably connected to the top of the bottom plate 15. The second adjustment member 32 is fixedly connected to the inner side of the first heat insulation plate 21 and the second heat insulation plate 22, and the first adjustment member 31 is fixedly connected to the outer side of the first heat insulation plate 21. The second heat insulation... A third adjusting member 33 is fixedly connected to the outer side of the first adjusting member 31. A first outer wall 11 is fixedly connected to the outer side of the first adjusting member 31. A second outer wall 12 is fixedly connected to the outer side of the third adjusting member 33. Multiple reinforcing rib grooves 211 are symmetrically arranged at equal intervals on the inner sides of the first heat insulation plate 21 and the second heat insulation plate 22. The first adjusting member 31 is composed of multiple first airbags 311, and each first airbag 311 is connected to the others through an air guide tube. The third adjusting member 33 is composed of multiple third airbags 331, and each third airbag 331 is connected to the others through an air guide tube. The second adjusting member 32 is composed of multiple second airbags 321, and each second airbag 321 is connected to the others through an air guide tube. The second airbags 321 are engaged with the reinforcing rib grooves 211. Inside, the first airbag 311, the second airbag 321, and the third airbag 331 are arranged linearly and equidistantly in the horizontal direction towards the centerline. The first airbag 311, the second airbag 321, and the third airbag 331 have pleated structures 3211 on their front and rear sides respectively. The second airbag 321 is connected to the second inflation port 115 and the second deflation port 116 via an air guide tube. The first airbag 311 and the third airbag 331 are connected by an air guide tube, and are also connected to the first inflation port 113 and the first deflation port 114 via the same air guide tube. When the first airbag 311 and the third airbag 331 are inflated through the first inflation port 113, the second airbag 321 deflates through the second deflation port 116, causing the first heat insulation plate 21 and the second heat insulation plate... When the first airbag 311 and the third airbag 331 deflate through the first air vent 114, the second airbag 321 inflates through the second air vent 115, thereby increasing the relative distance between the first heat insulation plate 21 and the second heat insulation plate 22. By controlling the inflation and deflation of the first airbag 311, the second airbag 321 and the third airbag 331, the relative distance between the first heat insulation plate 21 and the second heat insulation plate 22 can be decreased or increased. Then, for different heat insulation environments, by adjusting the distance between the first heat insulation plate 21 and the second heat insulation plate 22, the thickness of the heat insulation agent filled between the first heat insulation plate 21 and the second heat insulation plate 22 can be changed to achieve different heat insulation requirements.

[0031] The gases inside the first airbag 311, the second airbag 321, and the third airbag 331 are flame-retardant inert gases, improving the flame-retardant performance of the wall. The internal space of the insulation component 2 is divided into multiple independent spaces by the second airbag 321, enhancing the structural stability of the insulation component 2. In addition, in the event of a fire, its partition structure can slow the spread of fire. Furthermore, the first airbag 311, the second airbag 321, and the third airbag 331, with their gas insulation properties, can effectively reduce the heat transfer coefficient of the building envelope, achieving better thermal insulation effects compared to some traditional insulation materials (such as rock wool and polystyrene foam). Compared to other materials such as foam boards, airbags exhibit superior thermal insulation capabilities at the same thickness. Compared to many heavy block or board-shaped insulation materials, airbags are lighter in weight, do not impose excessive additional loads on the building structure, have less impact on the building's structural safety, and are easier to install. They help reduce the exchange of heat between indoors and outdoors, reduce heat loss in winter and heat transfer in summer, and achieve the purpose of energy saving and thermal insulation. In addition, the first insulation board 21 and the second insulation board 22 are equipped with first airbags 311, second airbags 321 and third airbags 331 on both the inner and outer sides, giving the wall good sound insulation capabilities.
