Description

Technical Field

[0001] This utility model relates to the technical field of building walls, and in particular to a prefabricated modular green building wall. Background Technology

[0002] Modular construction is a building technology that involves the direct hoisting, assembly, and installation of prefabricated components produced in batches in factories on-site. It is increasingly recognized and accepted due to its advantages such as shortening the construction cycle, reducing on-site labor, and minimizing construction waste. Existing modular buildings use composite prefabricated panels as walls within steel or concrete frame structures; these panels are often made of color-coated steel sheets with insulation material sandwiched in between. However, after a period of use, the insulation material of the wall panel is prone to aging, which can reduce the sound and heat insulation effect. In addition, most of the fillers in the existing technology are difficult to separate from the wall panel. Therefore, when improving the sound and heat insulation effect, it is usually necessary to remove the wall panel and replace it with a new one, which will greatly increase the utilization rate of waste. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a prefabricated modular green building wall to solve the technical problems mentioned in the background.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A prefabricated modular green building wall includes: The first frame is rectangular in shape, and the side wall of the first frame has a receiving cavity. The second frame includes a rectangular frame plate, which has the same shape as the first frame. Bolt holes are provided at the four corners of the rectangular frame plate, and threaded holes are provided at the corresponding positions of the bolt holes on the first frame. An insertion frame is provided on one side of the rectangular frame plate, and the insertion frame is positioned opposite to the receiving cavity; The first frame has a filling cavity inside, and a U-shaped frame is set inside the filling cavity. The two side plates of the U-shaped frame have protruding embedding blocks, and the two ends of the inner cavity wall of the filling cavity are provided with embedding grooves for matching the embedding blocks.

[0005] Furthermore, the bolt holes are countersunk holes, and connecting bolts are inserted inside the bolt holes to fix the second frame to the first frame.

[0006] Furthermore, after the first frame and the second frame are fixed together by connecting bolts, the insertion frame is inserted into the cavity, and the end face of the insertion frame contacts the bottom wall of the cavity.

[0007] Furthermore, after the second frame is connected and fixed to the first frame, the inner sidewall of the rectangular frame plate can limit the embedding block of the U-shaped frame. When the U-shaped frame is installed into the filling cavity, the embedding blocks on both sides of the U-shaped frame are respectively inserted into the embedding groove.

[0008] Furthermore, the embedded blocks on both sides of the U-shaped frame are staggered.

[0009] Furthermore, angle steel grooves are provided at the four corners of the first frame, and angle steel plates are embedded inside the angle steel grooves for connecting adjacent first frames.

[0010] In summary, this utility model has at least one of the following beneficial technical effects: 1. This prefabricated modular green building wall achieves initial internal fixation through the cooperation of the U-shaped frame's embedded block and the first frame's embedded groove. Subsequently, the second frame's insertion frame is aligned with the first frame's receiving cavity, and the two are fastened together with connecting bolts. After the bolts are tightened, the insertion frame penetrates into the receiving cavity to achieve radial limiting and filling fixation. At the same time, the rectangular frame plate of the second frame presses against the embedded blocks on both sides of the U-shaped frame to form axial limiting, together forming a stable whole. It can support bolt disassembly to achieve separation and recycling of the frame and filling material, meeting the requirements of green building for rapid assembly, disassembly, and reuse. 2. This prefabricated modular green building wall has embedded blocks on both sides of the U-shaped frame arranged in an alternating manner, which avoids slotting on the same cross section on both sides of the U-shaped frame, ensuring that the structural strength of the first frame sidewall is not weakened, transmitting stress more evenly, preventing stress concentration, and improving the overall stability and load-bearing capacity of the U-shaped frame after installation.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0019] Reference Figure 1 - Figure 5 This utility model discloses a prefabricated modular green building wall, comprising: The first frame 1 is rectangular in shape, and the side wall of the first frame 1 has a receiving cavity 11. The second frame 2 includes a rectangular frame plate 21, which has the same shape as the first frame 1. Bolt holes 22 are provided at the four corners of the rectangular frame plate 21, and threaded holes 12 are provided at the corresponding positions of the bolt holes 22 in the first frame 1. An insertion frame 23 is provided on one side of the rectangular frame plate 21, and the insertion frame 23 is positioned opposite to the receiving cavity 11; The first frame 1 has a filling cavity 13 inside, and a U-shaped frame 3U is provided inside the filling cavity 13. The two side plates of the U-shaped frame 3U have protruding embedding blocks 31, and the two ends of the internal cavity wall of the filling cavity 13 are provided with embedding grooves 14 for cooperating with the embedding blocks 31.

[0020] In this embodiment, the mechanical interlocking and bolt connection between the first frame 1 and the second frame 2 enables rapid and precise assembly; First, the U-shaped frame 3U with interlaced insert blocks 31 inside is pre-fixed in the filling cavity 13 of the first frame 1 through the cooperation of the insert blocks 31 and the insert groove 14, thus completing the initial installation of the internal structure. Then, the insertion frame 23 of the second frame 2 is aligned with the receiving cavity 11 of the first frame 1, and the connecting bolt 24 is passed through the bolt hole 22 of the second frame 2 and screwed into the threaded hole 12 of the first frame 1. After tightening the bolt, the two frames are tightly fixed as one unit. The insertion frame 23 penetrates into the receiving cavity 11 to achieve radial limitation, and the insertion hole can limit the heat insulation and sound insulation filling inside the receiving cavity 11. At the same time, the rectangular frame plate 21 of the second frame 2 forms axial compression and limitation on the embedded blocks 31 at both ends of the embedded U-shaped frame 3U, thus forming a stable and solid integral wall module. Adjacent modules can be connected by angle steel plates 4 to achieve wall assembly with a larger area. Furthermore, after assembly, the first frame 1 and the second frame 2 can be removed by disassembling the connecting bolts 24 at various locations, thereby removing the internal heat insulation and thermal insulation filling of the first frame 1, enabling the repeated and reusable use of the first frame 1 and the second frame 2, achieving the goal of green environmental protection.

[0021] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the bolt hole 22 is a countersunk hole, and a connecting bolt 24 is inserted inside the bolt hole 22 to fix the second frame 2 to the first frame 1.

[0022] In this embodiment, the bolt hole 22 is set as a countersunk hole, and the head of the connecting bolt 24 can be recessed into the hole without protruding from the surface of the second frame 2. By tightening the bolt, a strong clamping force is generated to firmly tighten and fix the second frame 2 and the first frame 1. The countersunk hole design ensures the flatness of the wall connection surface, which is convenient for subsequent decoration or module splicing. The bolt connection method is reliable and detachable, which not only meets the requirements of rapid construction of prefabricated buildings, but also facilitates future maintenance or modification.

[0023] In a further preferred embodiment of this utility model, such as Figure 2 As shown, after the first frame 1 and the second frame 2 are fixed by connecting bolts 24, the insertion frame 23 is inserted into the cavity 11, and the end face of the insertion frame 23 is in contact with the bottom wall of the cavity 11.

[0024] In this embodiment, during the bolt tightening process, the insertion frame 23 on the second frame 2 is inserted into the receiving cavity 11 on the side wall of the first frame 1. The end face of the insertion frame 23 eventually contacts the bottom wall of the receiving cavity 11, forming a tight fit, which can achieve precise positioning between the two frames and ensure the accuracy and efficiency of assembly. Meanwhile, the insertion frame 23 and the receiving cavity 11 effectively increase the contact area at the connection, significantly enhance the overall shear strength and stability of the wall, and help improve the airtightness and sound insulation performance at the joint.

[0025] In a further preferred embodiment of this utility model, such as Figure 3 As shown, after the second frame 2 is connected and fixed to the first frame 1, the inner sidewall of the rectangular frame plate 21 can limit the embedding block 31 of the U-shaped frame 3U. When the U-shaped frame 3U is installed into the filling cavity 13, the embedding blocks 31 on both sides of the U-shaped frame 3U are respectively inserted into the embedding groove 14.

[0026] In this embodiment, the embedded blocks 31 on both sides of the U-shaped frame 3U match the shape of the embedded grooves 14 on the inner wall of the filling cavity 13. During installation, the embedded blocks 31 are aligned and inserted into the embedded grooves 14 to achieve the initial positioning and fixation of the U-shaped frame 3U in the first frame 1, preventing it from shaking or shifting in the filling cavity 13. The cooperation between the embedded blocks 31 and the embedded grooves 14 bears the main vertical load of the U-shaped frame 3U and effectively transfers it to the main frame structure.

[0027] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the embedded blocks 31 on both sides of the U-shaped frame 3U are staggered.

[0028] In this embodiment, the embeddings on both sides of the U-shaped frame 3U are arranged in an alternating manner, which avoids slotting on the same cross-section on both sides of the U-shaped frame 3U, ensuring that the structural strength of the side wall of the first frame 1 is not weakened, transmitting stress more evenly, preventing stress concentration, and improving the overall stability and load-bearing capacity of the U-shaped frame 3U after installation.

[0029] In a further preferred embodiment of this utility model, such as Figure 3 As shown, angle steel grooves 15 are provided at the four corners of the first frame 1, and angle steel plates 4 are embedded inside the angle steel grooves 15 for connecting adjacent first frames 1.

[0030] In this embodiment, angle steel channels 15 are preset at the four corners of the first frame 1. When multiple wall modules need to be spliced ​​horizontally or vertically, L-shaped angle steel plates 4 are embedded into the angle steel channels 15 of two adjacent first frames 1 and then fixed with bolts or other means.

[0031] The implementation principle of the above embodiment is as follows: the green wall is initially fixed internally by the cooperation of the embedded block 31 of the U-shaped frame 3U with the embedded groove 14 of the first frame 1. Then, the insertion frame 23 of the second frame 2 is aligned with the receiving cavity 11 of the first frame 1, and the two are fastened with connecting bolts 24. After the bolts are tightened, the insertion frame 23 penetrates into the receiving cavity 11 to achieve radial limiting and filling fixation. At the same time, the rectangular frame plate 21 of the second frame 2 presses the embedded blocks 31 on both sides of the U-shaped frame 3U to form axial limiting, together forming a stable whole, which can support bolt disassembly to achieve separation and recycling of the frame and filling material, meeting the requirements of green building for rapid assembly, disassembly and reuse.

[0032] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
