DETAILED DESCRIPTION

[0027] The following examples further illustrate the content of the utility model, but should not be construed as limiting the utility model. Without departing from the spirit and essence of the utility model, modifications or replacements made to the methods, steps or conditions of the utility model are within the scope of the utility model.

[0028] Please refer to Figures 1 to 3 The utility model provides an ultra-low energy consumption modular prefabricated building system, comprising at least two building units connected vertically or horizontally, wherein the building unit comprises at least two wall panels 1 and a roof panel 2, wherein the wall panels 1 and the roof panel 2 are made of a steel skeleton thermal insulation decorative integrated panel, and the wall panels and the roof panel are connected by a first connecting component 3;

[0029] The wall panels and the top panels both include:

[0030] A frame, wherein the frame is formed by mutually perpendicular main ribs and secondary ribs connected in sequence through connecting pieces;

[0031] A double-layer steel wire mesh, comprising a first wire mesh welded to the frame and a second wire mesh arranged above the first wire mesh at a certain interval;

[0032] An integrated thermal insulation layer, comprising a thermal insulation layer laid between the double-layer steel wire mesh, the integrated thermal insulation layer comprising a foamed cement thermal insulation layer and upper and lower foamed concrete layers wrapped around the thermal insulation material layer;

[0033] The decorative layer is arranged on both sides of the integrated thermal insulation layer and is integrated with the exterior decoration material.

[0034] The frame structure plays a vital role as the supporting skeleton of the entire system. The frame is composed of mutually perpendicular main ribs and secondary ribs connected in sequence by connectors. This structural design makes the frame have high stability and bearing capacity, and can meet the needs of various complex building forms. The double-layer wire mesh not only ensures the stability of the wire mesh, but also provides good support for the insulation layer. The integrated insulation layer is the core part of the system, including the insulation layer laid between the double-layer wire mesh. The insulation layer adopts high-performance insulation materials with excellent insulation performance and durability. The integrated insulation layer also includes two layers of foamed concrete layers wrapped in the insulation material layer. The thermal insulation performance of the filled foamed concrete material is more than 11 times that of traditional concrete and 5.5 times that of traditional red bricks. The K value of the overall board can reach the passive wall level below 0.2, which effectively reduces heat transfer and achieves the energy-saving goal of the building.

[0035] In some embodiments, please refer to Figure 4 The main rib 101 of the top plate is made of a thin-walled channel steel in a stepped shape, including a first step surface 1011 and a second step surface 1012, the free end of the second step surface 1012 is bent upward to form a first clamping portion 1014, the upper end of the first step surface 1011 is vertically connected to a horizontal plate, and the free end of the horizontal plate is bent downward to form a second clamping portion 1013.

[0036] Thin-walled channel steel is a lightweight, high-strength steel material with good bending and compression resistance. In the design of the main rib of the top plate, the stepped structure of the thin-walled channel steel enables the crossbeam to remain stable under heavy pressure. In addition, the stepped design also makes the crossbeam have better bending resistance, further improving its service life and safety. The upper end of the first step surface 1011 is vertically connected to a horizontal plate. This design enhances the stability of the crossbeam and enables it to better disperse the load when subjected to force. The free end of the second step surface 1012 is bent upward to form a first clamping portion 1014. This design enables the main rib 101 of the top plate to have better bending resistance when subjected to vertical force, further improving its bearing capacity. The free end of the horizontal plate is bent downward to form a second clamping portion 1013. This design is intended to enhance the stability of the main rib 101 of the top plate in the horizontal direction, so that it can better resist deformation when subjected to force. In addition, the distance between the second clamping portion 1013 and the first clamping portion 1014 can be adjusted according to the actual application scenario and requirements to meet the installation requirements of different occasions. Its stepped design and clamping portion enable it to maintain good stability under heavy pressure and bending moment. Moreover, since the top plate main rib 101 is made of thin-walled channel steel, it has a light weight and is easy to install and carry. At the same time, the top plate main rib 101 has a simple structure and a low manufacturing cost, which is conducive to reducing the project cost.

[0037] In some embodiments, please refer to Figure 5 The top plate auxiliary rib 102 is made of C-shaped steel, including an integrally formed vertical plate 1021 and horizontal plates 1022 and 1023 vertically connected to the upper and lower ends of the vertical plate 1021, and the free ends of the horizontal plates 1022 and 1023 are bent inward to be parallel to the vertical plate 1021.

[0038] In some implementations, see Figure 6 The connecting member connecting the main rib 101 and the secondary rib 102 of the top plate is the second connecting member 103, and the second connecting member 103 includes a first connecting plate 1031 and a second connecting plate 1032 which are integrally formed perpendicular to each other. The second connecting plate 1031 is fixedly welded to the secondary rib 1032, and the second connecting plate 1032 has a first notch 1033 and a second notch 1034 on the upper and lower ends thereof which are matched with the first clamping portion 1014 and the second clamping portion 1013 on the main rib 101, the first clamping portion 1014 is clamped into the first notch 1033, and the second clamping portion 1013 is clamped into the second notch 1032.

[0039] The second connecting member 103 is stably connected to the top plate main rib 101 and the secondary rib 102 through the ingenious design of the first connecting plate 1031 and the second connecting plate 1032. This design not only improves the stability of the entire structure, but also makes the first connecting member 103 have higher accuracy and reliability in practical applications.

[0040] Please refer to Figure 7 The wall panel 2 uses square steel columns as main ribs 201 and C-shaped steel as secondary ribs 202, and the main ribs and secondary ribs of the wall panel are connected by a first connecting member 3.

[0041] In the construction process of the wall panel, the main rib 201 and the secondary rib 202 play a vital role. The square steel column as the main rib 201 provides the main support force for the wall panel, so that it has a high stability when subjected to external loads. The C-shaped steel as the secondary rib 202 helps to improve the bending and torsion resistance of the wall panel, so that it can still maintain good overall stability under complex stress conditions.

[0042] In some embodiments, please refer to Figure 8 The first connecting member 3 is in the shape of a square tube and is divided into two connecting parts, the main rib 201 of the wall panel and the secondary rib 202 of the wall panel are connected to the lower part of the first connecting member (3) by welding. The upper part of the first connecting member 3 is provided with bolt mounting holes on all four sides for connecting with other wall panels or top panels.

[0043] The first connecting member 3 is a square cylindrical structure, which is divided into two parts, upper and lower, which enhances its functionality. The lower connecting part is responsible for tightly connecting the main rib 201 of the wall panel and the auxiliary rib 202 of the wall panel. Bolt mounting holes are set on all four sides of the upper part of the first connecting member 3, which is convenient for connecting with other wall panels or top panels. This design fully reflects the modular thinking, making the building system more flexible and can be combined and adjusted according to actual needs. The design of the first connecting member 3 fully reflects functionality, stability and flexibility. Through clever structural design, it tightly connects the main ribs of the wall panel, the auxiliary ribs of the wall panel and the upper and lower connecting parts, ensuring the stability and safety of the entire wall panel. At the same time, the bolt mounting holes on the upper part facilitate the combination and adjustment of the building system. This design not only improves construction efficiency, but also reduces construction difficulty.

[0044] In some embodiments, Figure 6 As shown, both the first connecting plate 1031 and the second connecting plate 1032 are provided with drainage openings 1035 .

[0045] In some embodiments, the ultra-low energy consumption modular prefabricated building system also integrates water, electricity, heating and other pipelines. The pipelines are located in the frame, and their extension direction is parallel to the main ribs 101 of the top plate.

[0046] The pipelines are arranged in parallel with the main ribs of the top plate, which can reduce the bending of the pipelines inside the wall, reduce the loss of water flow, current and heat, and thus improve energy efficiency. The pipelines are arranged in parallel with the beams, so that the space inside the wall is fully utilized, avoiding the cross layout of the pipelines and reducing the difficulty and cost of construction. The ultra-low energy consumption modular prefabricated wall achieves efficient energy utilization and reasonable space allocation by integrating water, electricity, heating and other pipelines.

[0047] In some embodiments, the thickness of the insulation layer is 10 cm-15 cm, and the thermal conductivity of the foamed concrete layer is about 0.9 W / (mK).

[0048] In some embodiments, the decorative layer includes exterior materials such as dry-hanging tiles, stone, spray paint, and real stone paint.

[0049] The decorative surface tiles and stones of the product adopt the dry hanging process, and the foamed concrete is poured after the dry hanging, which solves the problem that the gap between the traditional dry hanging method and the wall is easy to break due to external impact. In addition, by integrating the exterior materials, the cost can be greatly saved.

[0050] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model based on the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
