Description

Technical Field

[0001] This application relates to the field of building component technology, and in particular to a prefabricated assembled wall unit. Background Technology

[0002] Precast wall units adopt a factory prefabrication production mode, which breaks down the wall into standardized modules, completes the processing through an industrialized assembly line, and transports them to the construction site. They are then assembled through mechanical hoisting and connectors to form a complete wall system. This mode breaks through the limitations of traditional cast-in-place walls that rely on on-site wet operations.

[0003] However, existing technologies have found that the assembly process for prefabricated walls is cumbersome and inconvenient, resulting in long on-site assembly time, reduced construction efficiency, and consequently, a long construction period. Utility Model Content

[0004] The purpose of this application is to provide a prefabricated assembled wall unit that has the advantages of improving the installation efficiency of prefabricated walls and shortening the construction time by positioning and locking the wedge block and the wedge groove with the limiting block and the groove, thus solving the problems mentioned in the background art.

[0005] This application provides a prefabricated assembled wall unit with the following technical solution: It includes two prefabricated walls. A fixing plate is fixedly connected to the left side of each prefabricated wall. A wedge block is fixedly connected to the left side of each fixing plate. A connecting strip is fixedly connected to the right side of each prefabricated wall. A wedge groove is formed on the right side of each connecting strip. A rubber gasket is fixedly embedded in the inner wall of each wedge groove. The outer surface of each wedge block is adapted to the inner wall of the corresponding wedge groove. Equally spaced limiting grooves are formed on the front and back of each connecting strip. A limiting block is slidably provided on the inner wall of each limiting groove. Equally spaced fixing bolts are fitted onto the inner wall of each wedge block. The outer surface of each fixing bolt is fitted to the inner wall of the corresponding limiting block. The outer surface of each fixing bolt is threadedly connected to the inner wall of the corresponding limiting block. Equally spaced slots are formed on the outer surface of each wedge block, and each slot is adapted to the corresponding limiting block.

[0006] By adopting the above technical solution, a fixing plate is installed on the left side of the precast wall to fix it. A wedge block is set on the left side of the fixing plate, and the fixing plate is fixed to the wedge block, so that when the precast wall is hoisted, the fixing plate and the wedge block can move together. A connecting strip is set on the right side of the precast wall, and the connecting strip is fixed to the precast wall, so that the precast wall and the connecting strip can also move together. A wedge groove is opened on the right side of the connecting strip to achieve positioning of the wedge groove. A rubber gasket is embedded in the inner wall of the wedge groove, and the wedge block is adapted to the wedge groove, so that the precast wall can be assembled with other precast walls through the connection of the wedge block and the wedge groove. When the wedge block and the wedge groove are connected, the rubber gasket can compensate for manufacturing errors. To absorb seismic energy, limiting grooves are created on the front and back of the connecting strip, and limiting blocks are placed on the inner walls of the corresponding limiting grooves. This allows the limiting grooves to position the limiting blocks. Fixing bolts are placed on the inner walls of the wedge blocks to position the fixing bolts. The fixing bolts pass through the corresponding limiting blocks and are threadedly connected to the limiting blocks on the other side, allowing the fixing bolts to lock the two limiting blocks in place. A slot is created on the outer surface of the wedge block, which is fitted with the limiting blocks. When the fixing bolts are rotated, the two corresponding limiting blocks move closer to each other and insert into the corresponding slots, thus connecting the two precast walls. The combination of groove positioning and locking with a snap-fit ​​mechanism improves the installation efficiency of the precast walls and shortens the construction time.

[0007] Preferably, each of the prefabricated walls includes an exterior finish layer.

[0008] By adopting the above technical solution, the precast wall is composed of multiple layers, with the outermost layer set as the exterior decorative layer, which serves as the overall exterior decorative surface and mainly plays the role of protecting the wall surface and decorating the appearance.

[0009] Preferably, a waterproof and breathable layer is provided on the back of each of the outer decorative layers, and each of the waterproof and breathable layers is made of a waterproof and breathable membrane.

[0010] By adopting the above technical solution, a waterproof and breathable layer is set on the back of the exterior layer, and the waterproof and breathable layer is made of a waterproof and breathable membrane, which can prevent rainwater from seeping in, while expelling the internal moisture of the wall to avoid condensation and mold.

[0011] Preferably, a fireproof layer is provided on the back of each of the waterproof and breathable layers, and each of the fireproof layers is made of fireproof gypsum board.

[0012] By adopting the above technical solution, the fireproof layer is placed on the back of the waterproof and breathable layer, and the fireproof layer is made of fireproof gypsum board. When a fire occurs, the fireproof layer can prolong the time for the fire to spread, thus buying time for personnel to evacuate.

[0013] Preferably, each of the fireproof layers has a thermal insulation layer on its back, and each thermal insulation layer is made of polyurethane board.

[0014] By adopting the above technical solution, setting the insulation layer on the back of the fireproof layer, and using polyurethane board for the insulation layer, the heat transfer can be reduced, and energy consumption can be lowered.

[0015] Preferably, a structural layer is provided on the back side of each of the insulation layers.

[0016] By adopting the above technical solution, a structural layer is set on the back of the insulation layer. The structural layer is made of light steel keel and concrete, and mainly serves to bear the self-weight of the wall and the loads of wind, earthquakes and other factors, so as to ensure structural safety.

[0017] Preferably, a sound insulation layer is provided on the back of each of the structural layers, and each of the sound insulation layers is made of centrifugal glass wool.

[0018] By adopting the above technical solution, the sound insulation layer is placed on the back of the structural layer, and the sound insulation layer is made of centrifugal glass wool. The installation of centrifugal glass wool can improve the overall sound insulation performance of the wall and prevent noise transmission from affecting residents' accommodation.

[0019] Preferably, an interior trim layer is provided on the back of each of the sound insulation layers.

[0020] By adopting the above technical solution, the interior layer is placed on the back of the sound insulation layer. As the inner layer of the whole wall, the interior layer has the effect of decorating the interior space and providing a smooth surface.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This prefabricated assembled wall unit, through the use of wedge blocks, limiting blocks, and fixing bolts, firstly, after hoisting the prefabricated wall, the wedge blocks are fitted with corresponding wedge grooves and slowly lowered, allowing the wedge blocks to slide within the wedge grooves. At this time, the rubber gaskets are compressed, compensating for manufacturing errors, generating preload, and absorbing seismic energy. Then, limiting blocks are installed within the limiting grooves. Fixing bolts are passed through corresponding limiting blocks and connected to limiting blocks on the other side, causing the corresponding limiting blocks to approach each other and insert into their corresponding grooves, thus completing the assembly of the prefabricated wall. The wedge blocks and wedge grooves provide a locking mechanism. The locking mechanism of the locking blocks and slots improves the installation efficiency of precast walls and shortens construction time. By setting a fireproof layer made of fire-resistant gypsum board between the exterior and insulation layers, the fireproof layer can delay the spread of fire in the event of a fire, buying time for evacuation. By setting a sound insulation layer made of centrifugal glass wool between the structural and interior layers, the overall sound insulation performance of the wall can be improved, preventing noise transmission from affecting residents' accommodations. Thus, this device can improve the overall fire resistance and sound insulation performance of precast walls, thereby significantly enhancing the safety and living comfort of buildings.

A connecting strip 4 is fixedly connected to the right side of each precast wall 1. The connecting strip 4 is placed on the right side of the precast wall 1 and fixed to the precast wall 1, allowing the precast wall 1 and connecting strip 4 to also move together. Moving together, each connecting strip 4 has a wedge-shaped groove 5 on its right side, and a rubber gasket 6 is fixedly embedded in the inner wall of each wedge-shaped groove 5. The outer surface of each wedge block 3 is adapted to the inner wall of the corresponding wedge-shaped groove 5.

The rubber gasket 6 is embedded in the inner wall of the wedge-shaped groove 5, and the wedge block 3 is adapted to the wedge-shaped groove 5, so that the precast wall 1 can be assembled with other precast wall 1 through the connection of the wedge block 3 and the wedge groove 5. When the wedge block 3 is connected to the wedge groove 5, the rubber gasket 6 can compensate for manufacturing errors and absorb seismic energy.

[0033] Please see Figure 1 , Figure 3 and Figure 5Each connecting strip 4 has equidistantly arranged limiting grooves 7 on both its front and back sides. Each limiting groove 7 has a sliding limiting block 8 on its inner wall. The limiting grooves 7 on the front and back sides of the connecting strip 4, and the limiting blocks 8 on the inner walls of the corresponding limiting grooves 7, allow the limiting grooves 7 to position the limiting blocks 8. Each wedge block 3 has equidistantly arranged fixing bolts 9 fitted onto its inner wall. The outer surface of each fixing bolt 9 fits into the inner wall of the corresponding limiting block 8, and the outer surface of each fixing bolt 9 is threaded into the inner wall of the corresponding limiting block 8. The fixing bolts 9 are positioned on the inner walls of the wedge blocks 3, thus achieving the positioning of the fixing bolts 9. 9 passes through the corresponding limiting block 8 and is threadedly connected to the limiting block 8 on the other side, so that the fixing bolt 9 can fix and lock the two limiting blocks 8. Each wedge block 3 has equally spaced slots 10 on its outer surface. Each slot 10 is adapted to the corresponding limiting block 8. The slots 10 are opened on the outer surface of the wedge block 3 and adapted to the limiting blocks 8, so that when the fixing bolt 9 is rotated, the two corresponding limiting blocks 8 move closer to each other and are inserted into the corresponding slots 10, so that the two corresponding prefabricated walls 1 can be connected to each other. The slot positioning connection and the snap-fit ​​locking fixation can improve the installation efficiency of the prefabricated wall 1 and shorten the construction time.

[0034] Example 2: A prefabricated assembled wall unit, please refer to... Figure 1 , Figure 2 and Figure 6 Each precast wall 1 includes an exterior decorative layer 101.

Then, the fixing bolt 9 is connected to the limiting block 8 on the other side, so that the limiting block 8 is inserted into the corresponding slot 10. At this time, the assembly of the precast wall 1 is realized. Through the positioning and cooperation of the wedge block 3 and the wedge groove 5, the locking of the limiting block 8 and the slot 10 can achieve... The installation efficiency of the precast wall 1 is improved and the construction time is shortened.
