Description

Technical Field

[0001] This application relates to buildings or similar structures for special purposes, and more specifically to the field of building construction technology, particularly to a prefabricated block wall and a construction method thereof. Background Technology

[0002] Prefabricated construction is a building structure system that the country has been vigorously developing in recent years. Because it allows for the on-site assembly of prefabricated components, it significantly reduces on-site wet work, shortens the construction period, improves project quality, and aligns with the requirements of green building principles. Infill walls, as non-load-bearing components in frame structures, frame-shear wall structures, shear wall structures, and tube structures, enable space division and maintenance, making them an important part of buildings.

[0003] For many years, infill walls have been constructed using manual on-site masonry. Because each block needs to be laid manually, the masonry work accounts for a large proportion of the entire construction cycle. Due to the varying skill levels of the masonry workers, the quality of the masonry work is inconsistent. Furthermore, since mortar is needed to bond the blocks together, a large amount of cement, sand, and other building materials are required, resulting in a large amount of wet work on-site and making it difficult to reuse the blocks after the walls are demolished, which is not conducive to the development of green buildings. Summary of the Invention

[0004] To address the issue of inconsistent masonry quality and the need for mortar bonding between masonry blocks, this application provides a prefabricated block wall and its construction method.

[0005] This application provides a prefabricated block wall and its construction method, which adopts the following technical solution: A prefabricated block wall includes a base, on the top surface of which structural columns for connecting blocks are symmetrically arranged, and on the side of the structural columns away from the base, a top cover for guiding flow is provided, and a plurality of blocks one, two and three are arranged between two structural columns. The interior of each of the blocks 1, 2 and 3 is provided with a connecting mechanism for snap-fitting, and the connecting mechanism includes a plug slot 1 for determining the snap-fitting position; The interior of block one, block two and block three are all provided with auxiliary mechanisms to prevent the blocks from tilting. The auxiliary mechanisms include connecting plates for determining the position. Several blocks 1, 2 and 3 are connected to an auxiliary mechanism to form a wall.

[0006] By adopting the above technical solution, the base serves as the foundation of the wall, bearing the load of the superstructure and transferring it to the ground to ensure overall stability. The structural columns serve as the vertical load-bearing skeleton, connecting laterally with the blocks to enhance the wall's resistance to lateral pressure. The top cover is used to guide rainwater to drain to both sides, preventing water accumulation from eroding the wall. Block 1, Block 2, and Block 3 serve as the main blocks of the wall, with internal connecting and auxiliary mechanisms to achieve rapid assembly. The connecting mechanism is used to vertically connect and snap the blocks together, while the auxiliary mechanism is used to prevent the blocks from tilting.

[0007] Preferably, the connecting mechanism further includes a second insertion slot, which is symmetrical to the first insertion slot and is located inside the first block. The inner walls of the first insertion slot and the second insertion slot are symmetrically fixedly connected with V-shaped clamping plates.

[0008] By adopting the above technical solution, the first and second insertion slots are symmetrically opened inside the block to form an insertion channel for the cross-shaped locking block, determine the horizontal locking position, and the V-shaped locking plate and the inclined surface of the cross-shaped locking block cooperate to generate a self-locking force to prevent the block from falling out.

[0009] Preferably, a cross-shaped locking block 1 that engages and matches with the first and second insertion slots is fixedly connected to the bottom surface of the block 1, and a cross-shaped locking block 2 that engages and matches with the first and second insertion slots is fixedly connected to the side of the block 1 away from the cross-shaped locking block 1.

[0010] By adopting the above technical solution, cross-shaped locking block one and cross-shaped locking block two are inserted into the interlocking slots of adjacent blocks to achieve vertical interlocking of the upper and lower blocks.

[0011] Preferably, a T-shaped groove is symmetrically provided on one side of the block, and a rectangular groove connected to the T-shaped groove is symmetrically provided on the side of the block near the T-shaped groove, and a slot is provided inside the T-shaped groove.

[0012] By adopting the above technical solution, T-shaped grooves and rectangular grooves are opened on the side of the block to provide a vertical sliding track for the T-shaped slider, and the slot is used to lock the position of the T-shaped slider.

[0013] Preferably, a T-shaped slider that is compatible with the T-shaped groove is fixedly connected to one side of the block away from the T-shaped groove, a limiting plate that is compatible with the rectangular groove is fixedly connected to the bottom surface of the T-shaped slider, and a retaining ring that is compatible with the retaining groove is fixedly connected to the outer surface of the T-shaped slider.

[0014] By adopting the above technical solution, the T-shaped slider is inserted into the T-shaped groove of the adjacent block to achieve horizontal connection. The limiting plate is used to limit the displacement of the T-shaped slider to prevent it from sliding excessively. The retaining ring is inserted into the groove to lock the slider and prevent it from rebounding and loosening.

[0015] Preferably, the auxiliary mechanism includes convex grooves symmetrically formed on one side of the block and connected to the insertion groove, and limit grooves symmetrically formed on the side of the block away from the convex groove.

[0016] By adopting the above technical solution, the convex groove connects to the insertion groove one and provides installation space for the rotating shaft, while the limiting groove is used to fix the connecting plate.

[0017] Preferably, the inner wall top surface of the convex groove is rotatably connected to a rotating shaft, and the outer surfaces of both ends of the rotating shaft are circumferentially arrayed with protrusions that are adapted to engage with the block.

[0018] By adopting the above technical solution, the rotating shaft is used to realize the rotation function. After the protrusion rotates with the rotating shaft, it is locked with the block to ensure that the connecting plate will not shift.

[0019] Preferably, the outer surface of the protrusion is fixedly connected to a pressure plate that is compatible with the convex groove.

[0020] By adopting the above technical solution, the pressure plate and the convex groove wedge are matched to ensure that the connecting plate can rotate.

[0021] Preferably, a connecting plate that is compatible with the limiting groove is fixedly connected to the outer surface of the rotating shaft on the side away from the pressure plate.

[0022] By adopting the above technical solution, the connecting plate rotates synchronously with the rotating shaft and is embedded in the limiting groove, thereby determining whether the block is in a vertical state.

[0023] The construction method for prefabricated block walls, applied to one type of prefabricated block wall mentioned above, includes the following steps: Step 1: Mechanically excavate the foundation and ensure that the foundation elevation is accurate and level with the ground. Backfilling is prohibited when the bottom of the trench is over-excavated. A concrete cushion layer must be used to fill the gap to the design elevation. During the rainy season, the slope gradient should be reduced or supports should be installed to prevent the risk of collapse. Step 2: Hoist the structural column onto the leveling support pre-embedded in the base, and then connect it to the top surface of the base with bolts and threads; Step 3: Connect the cross-shaped locking blocks 1 and 2 of block 1 to the top surface of the base, and connect them to the T-shaped sliding groove of block 2 through the T-shaped slider to form a connection. Also, the opposite surfaces of block 1, block 2 and the structural column are engaged. Step 4: The top surfaces of Block 1 and Block 2 are connected to the cross-shaped locking blocks 1 and 2 of Block 2 through the insertion slot 1 and insertion slot 2. At the end connection between Block 2 and the structural column, 1 / 2 of the masonry blocks are assembled. Step 5: A top cover is installed on top of the top layer.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By using cross-shaped locking blocks 1 and 2, which are fixed on block 1, block 2 and block 3 respectively, and inserting them into the corresponding insertion slots 1 and 2, the longitudinal alignment between the blocks can be accurately achieved, avoiding uneven masonry quality. When the cross-shaped locking blocks are inserted into the insertion slots, the V-shaped surface of the V-shaped locking plate generates a radial component force, forming a self-locking effect, which further compresses the cross-shaped locking blocks.

[0025] 2. By utilizing the T-shaped grooves, rectangular grooves, slots, T-shaped sliders, limiting plates, and retaining rings set on both sides of Block 1, Block 2, and Block 3, adjacent blocks can be connected laterally through the T-shaped grooves and T-shaped sliders. The slots and retaining rings are used to interlock with each other to fix the blocks laterally. This improves installation accuracy, reduces construction difficulty, and allows the wall to be disassembled and reused repeatedly, facilitating maintenance or secondary use. The presence of the limiting plates allows workers to accurately observe whether the blocks are connected in place, avoiding unevenness.

[0026] 3. By using the limiting grooves, pressure plates, and connecting plates set on the three sides of block one, block two, and block three, when the cross-shaped card block is inserted into the insertion groove, it will push the pressure plate to drive the connecting plate to rotate, so that the connecting plate is locked into the limiting groove. This controls the verticality of the blocks when stacking, and prevents the blocks from tilting when stacking. Compared with the existing technology of ensuring the verticality of the blocks by pulling a line, it is more convenient. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0030] Example 1 This application discloses a prefabricated block wall.

[0031] Reference Figure 1 , Figure 2 The wall of this invention belongs to the field of building construction technology, specifically a prefabricated block wall, including a base 1 formed by cement casting. The base 1 has threaded leveling supports embedded within it. The top surface of the base 1 is fixedly connected to two structural columns 2 on both sides. Threaded holes are opened at the bottom of the structural columns 2, and they are threadedly connected to the top surface of the base 1 by bolts. A top cover 3, triangular in shape, is fixedly connected to the top surface of the structural columns 2 via cement. The top cover 3 guides water to flow down its inclined surface. The opposite faces of the two structural columns 2 are interlocked with several blocks 5, 6, and 7. Blocks 5 and 6 are interlocked, and blocks 7 are interlocked between blocks 5 and 6. On the top surface of block 26, block 37 is stacked with blocks 15 and 26 in an alternating manner to improve the stability of the wall. Block 37 has the same length as blocks 15 and 26, but its width is reduced. When stacking, the blocks are stacked in a step-like manner from large to small. The blocks with decreasing size form a stepped structure with a wide bottom and a narrow top, forming a pyramid-like structure, which can significantly improve the overturning resistance. Several blocks 15, 26, and 37 are connected to the structural column 2 through the reinforcing column 4 to further improve stability. Several blocks 15, 26, and 37 are connected to the auxiliary mechanism to form the wall.

[0032] During use, the base 1 is mechanically excavated, and grooves for insertion and adaptation of cross-shaped clamping blocks 83 and 84 are reserved on the top surface of the base 1. It is ensured that the elevation of the base 1 is accurate and level with the foundation. Backfilling is prohibited when the bottom of the trench is over-excavated. A concrete cushion layer is required to fill the gap to the design elevation. During the rainy season, the slope gradient should be reduced or supports should be installed to prevent the risk of collapse. Subsequently, structural columns 2 are welded on the top surface of the base 1. Several blocks 5, 6, and 7 are stacked on the opposite sides of the two structural columns 2. After the blocks 5, 6, and 7 are stacked, a top cover 3 is fixed on the top surface of the structural columns 2 and the blocks 7 to guide water flow. Reinforcing columns 4 are inserted between the blocks and the structural columns 2 in each layer to improve stability.

[0033] Reference Figures 3-5 Block 5, Block 6, and Block 7 are all equipped with connecting mechanisms. These mechanisms include a first insertion slot 81 inside Block 5 and a second insertion slot 82 inside Block 5, which are symmetrical to the first insertion slot 81. The inner walls of both the first and second insertion slots 81 are fixedly connected to V-shaped clamping plates 85, which are symmetrically fixed to the inner walls of the first and second insertion slots 81. The surface being compressed can generate radial force, further improving the strength of the connection between blocks. One side of the bottom surface of block 5 is fixedly connected to cross-shaped locking block 83. Cross-shaped locking block 83 is matched with interlocking slot 81 and interlocking slot 82. One side of block 5 is fixedly connected to cross-shaped locking block 84. Cross-shaped locking block 84 is located on the side away from cross-shaped locking block 83, and cross-shaped locking block 84 is matched with interlocking slot 81 and interlocking slot 82.

[0034] In use, the cross-shaped locking block 1 83 or cross-shaped locking block 2 84 fixed to block 3 7 can be aligned with the insertion slot 1 81 or insertion slot 2 82 opened on block 1 5 or block 2 6, and the cross-shaped locking block 1 83 or cross-shaped locking block 2 84 can be inserted into the insertion slot 1 81 or insertion slot 2 82. Since the insertion slot 1 81 and insertion slot 2 82 are both fixed with V-shaped locking plates 85, when the cross-shaped locking block 1 83 enters the insertion slot 1 81 or insertion slot 2 82, it will squeeze the V-shaped locking plate 85, so that the V-shaped surface of the V-shaped locking plate 85 is squeezed to generate radial force, which in turn squeezes the cross-shaped locking block 1 83 or cross-shaped locking block 2 84, thereby improving the connection strength.

[0035] Reference Figures 4-7Two T-shaped grooves 86 are symmetrically arranged on one side of block 5. Two rectangular grooves 87 are also provided on one side of block 5, located near the bottom of the T-shaped grooves 86 and connected to them. A slot 88 is provided at the bottom of the inner wall of each of the two T-shaped grooves 86. One side of block 5 is fixedly connected to a T-shaped slider 89, which is located at the far side. On one side of the T-shaped slide 86, and the T-shaped slider 89 is engaged with the T-shaped slide 86, the bottom surface of one side of the block 5 is fixedly connected to the limiting plate 810. The limiting plate 810 is located on the side close to the T-shaped slider 89. The limiting plate 810 is fixedly connected to the bottom surface of the T-shaped slider 89, and the limiting plate 810 is engaged with the rectangular groove 87. The lower part of the outer surface of the T-shaped slider 89 is fixedly connected to the retaining ring 811, and the retaining ring 811 is engaged with the retaining groove 88.

[0036] In use, the T-shaped groove 86 of block 2 6 is engaged from top to bottom with the T-shaped slider 89 fixed in block 1 5. When the T-shaped groove 86 slides on the outer surface of the T-shaped slider 89 to the bottom of the T-shaped slider 89, the groove 88 engages with the retaining ring 811, and the rectangular groove 87 engages with the limiting plate 810. The engagement of the limiting plate 810 can restrict block 2 6 and prevent block 2 6 from moving excessively, thereby ensuring that the positions of block 1 5 and block 2 6 are flush. The engagement of the groove 88 and the retaining ring 811 ensures that block 1 5 and block 2 6 are tightly connected.

[0037] Reference Figure 3 , Figure 5 , Figure 8Each of the blocks 5, 6, and 7 has an auxiliary mechanism inside. This auxiliary mechanism includes two convex grooves 91 on one side of block 5. These two grooves are symmetrical and communicate with insertion grooves 81 and 82. Two limiting grooves 92 are also provided on one side of block 5, located away from the convex grooves 91. These limiting grooves are symmetrical, and the convex grooves 91, limiting grooves 92, insertion grooves 81 and 82 are aligned. The top surface of the inner wall of the convex groove 91 is rotatably connected to a rotating shaft 93. A notch is provided on the side of block 5 near the convex groove 91 to accommodate the insertion of the rotating shaft 93, allowing the shaft 93 to rotate within this notch. Both ends of the rotating shaft 93 have circumferentially arranged outer surfaces. Several protrusions 94 are provided. The protrusions 94 are engaged with the inner wall of block 5. The outer surface of the middle part of the protrusion 94 is fixedly connected to the pressure plate 95. The pressure plate 95 is engaged with the convex groove 91. The outer surface of one side of the rotating shaft 93 is fixedly connected to the connecting plate 96. The connecting plate 96 is located away from the pressure plate 95. The connecting plate 96 is engaged with the limiting groove 92 to achieve limiting and positioning. The pressure plate 95 and the connecting plate 96 are on the same straight line. In the initial state, the pressure plate 95 and the connecting plate 96 are horizontal. The pressure plate 95 is located inside the insertion groove 1 81 and the insertion groove 2 82. The interiors of block 5, block 2 6, block 3 7, cross-shaped locking block 1 83 and cross-shaped locking block 2 84 are all provided with through holes 97. The reinforcing column 4 can be inserted into the interior of the through hole 97.

[0038] When in use, when the cross-shaped locking block 1 83 or cross-shaped locking block 2 84 fixed to block 3 7 is inserted into the insertion slot 1 81 or insertion slot 2 82, it will push the pressure plate 95 to deflect downward. At the same time as the pressure plate 95 deflects, it will drive the rotating shaft 93 fixedly connected to the pressure plate 95 to rotate. The rotation of the rotating shaft 93 will drive the connecting plate 96 fixedly connected to the rotating shaft 93 to rotate, and cause the connecting plate 96 to engage into the limiting groove 92 opened in block 3 7, thereby controlling the verticality of the blocks when stacking and preventing the blocks from tilting when stacking.

[0039] The implementation principle of a prefabricated block wall according to an embodiment of this application is as follows: During use, the base 1 is mechanically excavated, and matching slots for insertion and adaptation of cross-shaped locking blocks 83 and 84 are reserved on the top surface of the base 1, ensuring that the elevation of the base 1 is accurate and level with the foundation. Subsequently, structural columns 2 are welded to the top surface of the base 1. Several blocks 5, 6, and 7 are stacked and clamped on the opposite sides of the two structural columns 2. The T-shaped sliding groove 86 opened in block 26 is clamped from top to bottom into the T-shaped sliding block 89 fixed in block 15, and the T-shaped sliding groove 86 is clamped into the T-shaped sliding block 89 fixed in block 15. When the slide groove 86 slides to the bottom of the T-shaped slider 89 on the outer surface of the T-shaped slider 89, the slot 88 will engage with the retaining ring 811, and the rectangular groove 87 will engage with the limiting plate 810. The engagement of the limiting plate 810 can restrict the second block 6 and prevent the second block 6 from moving excessively, thereby ensuring that the first block 5 and the second block 6 are level. The engagement of the slot 88 with the retaining ring 811 ensures that the first block 5 and the second block 6 are tightly connected, and the first block 5 and the second block 6 form the bottom layer. Subsequently, the cross-shaped locking block 1 83 or cross-shaped locking block 2 84 fixed to block 3 7 is aligned with the insertion slot 1 81 or insertion slot 2 82 opened on block 1 5 or block 2 6, and the cross-shaped locking block 1 83 or cross-shaped locking block 2 84 is inserted into the insertion slot 1 81 or insertion slot 2 82. When the cross-shaped locking block 1 83 enters the interior of the insertion slot 1 81 or insertion slot 2 82, the V-shaped locking plate 85 is squeezed, causing the V-shaped surface of the V-shaped locking plate 85 to be squeezed and generate radial force, thereby squeezing the cross-shaped locking block 1 83 or cross-shaped locking block 2 84 and improving the connection strength. When the cross-shaped locking block 83 or the cross-shaped locking block 84 is inserted into the insertion slot 81 or the insertion slot 82, it will push the pressure plate 95 to deflect downward. At the same time, the pressure plate 95 will drive the rotating shaft 93 fixedly connected to the pressure plate 95 to rotate. The rotation of the rotating shaft 93 will drive the connecting plate 96 fixedly connected to the rotating shaft 93 to rotate, and cause the connecting plate 96 to engage with the limiting groove 92 opened in the block body 7, thereby controlling the verticality of the blocks during stacking and preventing the blocks from tilting during stacking. After several blocks 1 (5), 2 (6), and 3 (7) are stacked, a top cover 3 is fixed on the top surface of the structural column 2 and the top surface of the third block 7 to guide the water flow. A reinforcing column 4 is inserted between the blocks and the structural column 2 of each layer to improve stability.

[0040] Example 2 The construction method for prefabricated block walls, applied to one type of prefabricated block wall mentioned above, includes the following steps: Step 1: Mechanically excavate the base 1, and reserve matching slots on the top surface of the base 1 for insertion and adaptation of cross-shaped clamping block 1 83 and cross-shaped clamping block 2 84. symmetrically fix V-shaped clamping plates 85 in the slots to clamp cross-shaped clamping block 1 83 and cross-shaped clamping block 2 84, ensuring that the elevation of the base 1 is accurate and level with the foundation. Backfilling is prohibited when the bottom of the trench is over-excavated; a concrete cushion layer must be used to fill to the design elevation. During the rainy season, the slope gradient must be reduced or supports must be installed to prevent the risk of collapse. Threaded leveling supports are pre-embedded in the base 1. Step 2: Threaded holes are made at the bottom of structural column 2. Structural column 2 is hoisted onto the leveling support pre-embedded in base 1. Then, it is connected to the top surface of base 1 by bolts and the verticality is calibrated by laser. Step 3: The cross-shaped locking block 1 83 and cross-shaped locking block 2 84 of block 1 5 are inserted into the top surface of base 1, and the T-shaped slider 89 is engaged with the T-shaped groove 86 of block 2 6 to form a connection. The opposite surfaces of block 1 5, block 2 6 and structural column 2 are engaged with the T-shaped slider 89 through the T-shaped groove 86. Step 4: The top surfaces of Block 1 5 and Block 2 6 are connected to the cross-shaped locking blocks 1 83 and 2 84 of Block 2 6 through the interlocking slots 1 81 and 2 82. Half of the blocks are assembled at the connection point between Block 2 6 and the end of the structural column 2. When Block 3 7 is stacked with Block 1 5 and Block 2 6, their positions are staggered to improve the stability of the wall. Block 3 7 has the same length as Block 1 5 and Block 2 6, but its width is reduced. When stacking, the blocks are stacked in a step-like manner from large to small. The blocks with decreasing size form a stepped structure with a wide bottom and a narrow top, forming a pyramid-like structure, which can significantly improve the overturning resistance. Step 5: A top cover 3 is installed on the top of the top layer. The top cover 3 is triangular and is used to guide water to flow down the slope of the top cover 3.
