Description

Technical Field

[0001] This invention belongs to the field of building wall structure technology, specifically relating to a prefabricated building energy-saving wall structure. Background Technology

[0002] Prefabricated buildings have become a form of construction strongly advocated by the state. Local governments at all levels are actively promoting prefabricated buildings based on local conditions and policies tailored to each city. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods.

[0003] In the prior art, the walls of prefabricated houses are subject to significant thermal expansion and contraction, while their sound insulation effect is relatively low compared to traditional walls. For example, Chinese Patent Publication No. CN215368012U, published on December 31, 2021, discloses a prefabricated building energy-saving wall structure panel, which includes prefabricated structural panels, sealing strips, square tubes, and limiting pins. Several prefabricated structural panels are respectively set on both sides of the main ring beam of the building. Several parallel square tubes are set inside the main ring beam of the building. A first through hole is provided in the middle of the square tube. A limiting pin is installed inside each square tube. The two ends of the limiting pin are respectively connected to one end of a prefabricated structural panel. Several prefabricated structural panels are all set parallel to each other. Sealing strips are set between pairs of prefabricated structural panels, and pairs of prefabricated structural panels are connected by filling adhesive.

[0004] The invention features a sealing strip structure connected by an adhesive filler. However, when building wall panels are affected by temperature differences, they will expand and contract due to heat. During this process, the wall panels may bend or crack. Although the construction is simple and the installation is quick, it cannot solve the problems of thermal expansion and contraction between walls and sound insulation, making it inconvenient to use in practice. Currently, there is an urgent need for a prefabricated building energy-saving wall structure panel that is simple in structure, quick to install, has good sound insulation, and can alleviate the deformation caused by thermal expansion and contraction. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a prefabricated building energy-saving wall structure. This prefabricated building wall structure aims to solve the problem that existing technologies connect wall panels using adhesives, which can lead to thermal expansion and contraction when the wall panels are affected by temperature differences. During this process, the wall panels may bend or crack. Although the construction is simple and the installation is quick, it cannot solve the problems of thermal expansion and contraction between walls and sound insulation, making it inconvenient to use in practice. Currently, there is an urgent need for a prefabricated building energy-saving wall structure panel that is simple in structure, quick to install, has good sound insulation, and can alleviate the deformation caused by thermal expansion and contraction.

[0006] To address the aforementioned technical problems, this invention provides a prefabricated building energy-saving wall structure. This prefabricated building wall structure includes multiple end-to-end connected building wall panels and a connecting frame for fixing the multiple building wall panels. The side walls of the building wall panels are provided with anti-deformation grooves, and both ends of the building wall panels are fixed with connecting parts. Both ends of the connecting frame are fixedly connected with mounting plates. The mounting plates are provided with outer wall panels that fit against the side walls of the connecting parts, and a second expansion cavity is provided between the mounting plates and the two connecting parts. A first expansion cavity is provided between the outer wall panels and the two building wall panels.

[0007] When using the prefabricated building wall structure of this technical solution, a connecting frame is set between two adjacent building wall panels. The connecting frame fixes multiple building wall panels end to end, and an outer wall panel for protecting the side wall connection of the building wall panels is fixed to the connecting frame through mounting plates at both ends. A second expansion cavity is set between the mounting plate and the two connecting parts, and a first expansion cavity is set between the outer wall panel and the two building wall panels. When the outer wall panel expands due to heat, the expansion generated at the connecting parts moves into the second expansion cavity, and the expansion generated by the building wall panel moves into the first expansion cavity. During the movement, it is avoided that the two adjacent building wall panels are squeezed by each other due to the expansion, which would cause the panels to bend. By opening multiple anti-deformation grooves on the side wall of the building wall panel, when the temperature of the building wall panel decreases and it contracts, the contraction of the building wall panel itself pulls the anti-deformation grooves to enlarge, and the inner wall of the vertically set anti-deformation groove is stretched. The inclined design, with its anti-deformation grooves, withstands the shrinkage of the building wall panels, preventing surface cracks during shrinkage and improving the wall panels' resistance to thermal expansion and contraction. Simultaneously, sound insulation panels are embedded within the wall panels. Sound-absorbing holes in the sound insulation panels absorb and partially eliminate sound waves, while sound-absorbing grooves within the panels absorb the remaining sound waves, further enhancing the wall panels' sound insulation. Elastic plates are fixed at both ends of the connecting frame, with grooves between them. As the elastic plates are inserted into the grooves, their locking parts abut against the inner wall of the grooves, causing the plates to elastically deform and shrink into the grooves. Once fully inserted, the elastic plates push the locking parts into the grooves, abutting against the inner wall, thus securing both ends of the connecting frame to the wall panels and improving the ease of installation.

[0008] Preferably, elastic plates are symmetrically fixed at both ends of the connecting frame, and grooves are provided between the elastic plates and the connecting frame.

[0009] Furthermore, a connecting groove is provided at the center of the side wall of the connecting part, and a trapezoidal slot is provided on the inner wall of the connecting groove.

[0010] Furthermore, the elastic plates at both ends of the connecting frame are slidably inserted into the connecting groove and are tightly connected to the inner wall of the connecting groove.

[0011] Furthermore, the side wall of the elastic plate is provided with a trapezoidal snap-fit ​​part, which fits into the slot.

[0012] Furthermore, the top of the connecting frame is provided with a screw hole, a handle is threaded into the screw hole, and an anti-slip sleeve is fixedly fitted to the top of the handle.

[0013] Furthermore, the building wall panel has a hollow cavity inside, and a sound insulation board is embedded and fixed inside the hollow cavity.

[0014] Furthermore, the sound insulation board has multiple sound-absorbing holes at both ends, and a sound-absorbing groove connected to the sound-absorbing holes is provided at the center of the sound insulation board.

[0015] Furthermore, all of the aforementioned sound-absorbing holes are arranged in a honeycomb structure, and a sound-absorbing plate is embedded and fixed in the sound-absorbing groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention provides a connecting frame between two adjacent building wall panels, which securely connects multiple building wall panels end-to-end. The connecting frame is secured with an outer wall panel at each end by mounting plates for protecting the sidewall connections of the building wall panels. A second expansion cavity is provided between the mounting plate and the two connecting parts, and a first expansion cavity is provided between the outer wall panel and the two building wall panels. When the outer wall panel expands due to heat, the expansion generated at the connecting parts moves into the second expansion cavity, and the expansion generated by the building wall panel moves into the first expansion cavity. During this movement, the expansion of adjacent building wall panels prevents them from being squeezed together and bending. Multiple anti-deformation grooves are provided on the sidewalls of the building wall panels. When the temperature of the building wall panel decreases and it contracts, the contraction of the building wall panel itself pulls the anti-deformation grooves larger, causing the vertically arranged inner walls of the anti-deformation grooves to be tilted. The anti-deformation grooves withstand the contraction of the building wall panel, preventing cracks from appearing on the surface of the building wall panel during contraction and improving the thermal expansion and contraction resistance of the building wall panel.

[0018] 2. Sound insulation panels are embedded in the building wall panels. The sound-absorbing holes on the sound insulation panels absorb and partially eliminate sound waves, while the sound-absorbing grooves in the sound insulation panels absorb the remaining sound waves, thus improving the sound insulation effect of the building wall panels. Elastic plates are fixed at both ends of the connecting frame, and grooves are provided between the elastic plates and the connecting frame. During the insertion of the elastic plates into the connecting grooves, the snap-fit ​​parts on the elastic plates abut against the inner wall of the connecting grooves, causing the elastic plates to elastically deform and shrink into the grooves. Until the elastic plates are fully inserted into the connecting grooves and snap-fit ​​grooves, the elasticity of the elastic plates pushes the snap-fit ​​parts to fit into the snap-fit ​​grooves and abut against the inner wall of the snap-fit ​​grooves, thereby fixing both ends of the connecting frame to the building wall panels, improving the ease of installation of the building wall panels.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown in the figure, a prefabricated building energy-saving wall structure according to a preferred embodiment of the present invention has the following structural schematic diagram. Figure 1 As shown, the prefabricated building wall structure includes multiple wall panels 1 connected end-to-end and a connecting frame 16 for fixing the multiple wall panels 1. The side walls of the wall panels 1 are provided with anti-deformation grooves 9, and both ends of the wall panels 1 are fixed with connecting parts 2. Both ends of the connecting frame 16 are fixedly connected with mounting plates 15. The mounting plates 15 are provided with outer wall panels 4 that fit against the side walls of the connecting parts 2, and a second expansion cavity 6 is provided between the mounting plates 15 and the two connecting parts 2. A first expansion cavity 5 is provided between the outer wall panels 4 and the two wall panels 1. A connecting frame 16 is provided between two adjacent wall panels 1. The connecting frame 16 fixes the multiple wall panels 1 end-to-end, and the connecting frame 16 is fixed with mounting plates 15 at both ends to protect the side walls of the wall panels 1. The outer wall panel 4 of the connecting part 2 has a second expansion cavity 6 between the mounting plate 15 and the two connecting parts 2, and a first expansion cavity 5 between the outer wall panel 4 and the two building wall panels 1. When the outer wall panel 4 expands due to heat, the expansion generated by the connecting part 2 moves into the second expansion cavity 6, and the expansion generated by the building wall panel 1 moves into the first expansion cavity 5. During the movement, the two adjacent building wall panels 1 are prevented from being squeezed by each other due to the expansion, which would cause the panels to bend. By opening multiple anti-deformation grooves 9 on the side wall of the building wall panel 1, when the temperature of the building wall panel 1 decreases and it shrinks due to cold, the shrinkage of the building wall panel 1 itself pulls the anti-deformation grooves 9 to become larger. The inner wall of the vertically set anti-deformation grooves 9 is pulled into an inclined position, and the anti-deformation grooves 9 withstand the shrinkage of the building wall panel 1.

[0029] Based on the above embodiment, elastic plates 10 are symmetrically fixed at both ends of the connecting frame 16, and a groove 13 is provided between the elastic plate 10 and the connecting frame 16.

[0030] In addition, a connecting groove 3 is provided at the center of the side wall of the connecting part 2, and a trapezoidal slot 11 is provided on the inner wall of the connecting groove 3.

[0031] Furthermore, the elastic plates 10 at both ends of the connecting frame 16 are slidably inserted into the connecting groove 3 and are tightly connected to the inner wall of the connecting groove 3.

[0032] More specifically, the side wall of the elastic plate 10 is provided with a trapezoidal snap-fit ​​part 12, which fits into the snap-fit ​​groove 11.

[0033] With the above-mentioned structural cooperation, a groove 13 can be provided between the elastic plate 10 and the connecting frame 16. During the process of inserting the elastic plate 10 into the connecting groove 3, the snap-fit ​​part 12 on the elastic plate 10 abuts against the inner wall of the connecting groove 3, thereby causing the elastic plate 10 to elastically deform and shrink into the groove 13 until the elastic plate 10 is fully inserted into the connecting groove 3 and the snap-fit ​​groove 11. The elasticity of the elastic plate 10 pushes the snap-fit ​​part 12 to fit into the snap-fit ​​groove 11 and abut against the inner wall of the snap-fit ​​groove 11, thereby fixing both ends of the connecting frame 16 to the building wall panel 1 respectively.

[0034] Furthermore, based on the above embodiment, a screw hole 14 is provided at the top of the connecting frame 16, and a handle 7 is threaded into the screw hole 14. An anti-slip sleeve 8 is fixedly sleeved on the top of the handle 7. By threading the handle 7 into the screw hole 14 at the top of the connecting frame 16, it is easy to move the connecting frame 16. After installation, the handle 7 can be unscrewed from the screw hole 14 for disassembly. A hollow cavity is provided inside the building wall panel 1, and a sound insulation board 17 is embedded and fixed in the building wall panel 1 through the hollow cavity. Multiple sound-absorbing holes 18 are provided at both ends of the sound insulation panel 17, and a sound-absorbing groove 19 connected to the sound-absorbing holes 18 is provided at the center of the sound insulation panel 17. The multiple sound-absorbing holes 18 are arranged in a honeycomb structure. A sound-absorbing plate 20 is embedded and fixed in the sound-absorbing groove 19. The sound-absorbing holes 18 on the sound insulation panel 17 absorb and partially eliminate sound waves, and the sound-absorbing plate 20 in the sound-absorbing groove 19 on the sound insulation panel 17 absorbs the remaining sound waves, thereby improving the sound insulation effect of the building wall panel 1.

[0035] Working principle: When installing the building wall panel 1, the elastic plate 10 on the connecting frame 16 is inserted into the connecting groove 3 on the connecting part 2. During the insertion process, the snap-fit ​​part 12 on the elastic plate 10 abuts against the inner wall of the connecting groove 3, causing the elastic plate 10 to elastically deform and shrink into the groove 13 until the elastic plate 10 is fully inserted into the connecting groove 3 and the snap-fit ​​groove 11. The elasticity of the elastic plate 10 pushes the snap-fit ​​part 12 to fit into the snap-fit ​​groove 11 and abut against the inner wall of the snap-fit ​​groove 11, thereby fixing both ends of the connecting frame 16 to the building wall panel 1. The connecting frame 16 fixes multiple building wall panels 1 end to end, and the connecting frame 16 is fixed with an outer wall panel 4 for protecting the side wall connecting part 2 of the building wall panel 1 through the mounting plates 15 at both ends. A space is set between the mounting plate 15 and the two connecting parts 2. There is a second expansion cavity 6, and a first expansion cavity 5 is provided between the outer wall panel 4 and the two building wall panels 1. When the outer wall panel 4 expands due to heat, the expansion generated by the connecting part 2 moves into the second expansion cavity 6, and the expansion generated by the building wall panel 1 moves into the first expansion cavity 5. During the movement, the two adjacent building wall panels 1 are prevented from being squeezed by each other due to the expansion, which would cause the panels to bend. By providing multiple anti-deformation grooves 9 on the side wall of the building wall panel 1, when the temperature of the building wall panel 1 decreases and it contracts, the contraction of the building wall panel 1 itself pulls the anti-deformation grooves 9 to become larger. The inner wall of the vertically set anti-deformation grooves 9 is pulled into an inclined position. The anti-deformation grooves 9 bear the contraction of the building wall panel 1, which prevents the surface of the building wall panel 1 from cracking during the contraction process, thus improving the anti-thermal expansion and contraction effect of the building wall panel 1.
