Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of autoclaved aerated blocks, and particularly relates to an anti-cracking autoclaved aerated block. Background Technique
[0002] In recent years, autoclaved aerated concrete has developed vigorously in the Chinese building materials market. As a substitute for solid clay bricks, it has become an important development trend in the Chinese building materials industry. Autoclaved aerated concrete blocks, as a new type of wall material, are made by adding aluminum powder as an aerating agent to the mixture of calcareous materials and siliceous materials, and then through multiple processes such as adding water and stirring, casting and molding, gas expansion, pre-curing and cutting, and high-pressure steam curing, finally making porous silicate blocks. These blocks have multiple advantages such as light weight, high strength, heat preservation, heat insulation, sound absorption, fire prevention, and good workability.
[0003] However, in order to improve the anti-tearing performance of autoclaved aerated concrete blocks, a block structure with a fiber frame and a fiber mesh has been introduced in the industry, such as the anti-cracking autoclaved aerated block described in the Chinese utility model patent document with the publication number CN219548140U. Although the fiber mesh significantly enhances the overall structure of the block, there are still obvious defects in this method.
[0004] First of all, the fiber frame needs specific grooves and holes to be fixed during the pouring process, and this design greatly limits its versatility and adaptability to different-sized blocks or molds. Secondly, forming grooves and holes inside the block may weaken its overall structural strength and affect the use performance of the block. Moreover, although the fiber mesh can absorb water molecules in the cement and expand to form a highly ductile composite material, this process is also prone to causing the block to deform during the drying process, thereby affecting its flatness and appearance aesthetics. Finally, although the stacking method is relatively convenient, this fixed stacking method also limits the stacking flexibility of the block and the diversity of application scenarios.
[0005] Therefore, it is very necessary to invent an anti-cracking autoclaved aerated block. Content of the Utility Model
[0006] In order to solve the above technical problems, the utility model provides an anti-cracking autoclaved aerated block, which includes a fiber mesh frame, a bottom-sealing pouring part, a batch pouring part, a top-sealing pouring part, and a distributed fiber mesh. The fiber mesh frame and the distributed fiber mesh are both arranged inside the bottom-sealing pouring part, the batch pouring part, and the top-sealing pouring part; and a plurality of distributed fiber meshes are provided.
[0007] Preferably, the fiber mesh frame is a square mesh frame structure made by weaving fiber filaments on twelve struts, where the twelve struts together construct a complete square frame structure; the fiber mesh frame does not penetrate through the bottom casting part and the top casting part, and the thickness from not penetrating through the bottom casting part or the top casting part is not less than two centimeters thick.
[0008] Preferably, the distributed fiber mesh is a mesh structure woven from square fiber filaments, and several of the distributed fiber meshes are vertically distributed, located between each of the batch casting parts, as well as between the bottom casting part or the top casting part and the batch casting part.
[0009] Preferably, the bottom casting part and the top casting part have the same thickness, but the thickness of both is greater than or equal to the thickness of the batch casting part.
[0010] Compared with the prior art, the present utility model has the following beneficial effects:
[0011] The present utility model provides an innovative pouring method and structure, significantly improving its tear resistance strength. First, a thin slurry layer is poured as the fiber mesh stabilizing base to ensure uniform embedding of the fiber mesh and form a stable structure. Subsequently, the square fiber mesh is inserted as a reinforcement material to effectively resist external forces and delay the generation of cracks. Subsequently, the fiber meshes are placed layer by layer, with each layer of slurry covered by a layer of fiber mesh to form a multi-layer reinforcement structure, ensuring the overall tear resistance performance of the building block. The fiber mesh inside enhances the internal connection of the building block and improves the overall strength. When the fiber mesh is subjected to external forces, it consumes energy through stretching and breaking, significantly enhancing the tear resistance performance.
[0012] In addition, this pouring process ensures the tight combination of the fiber mesh and the slurry, avoiding voids and defects, and further improving the overall strength of the building block. This innovative pouring method and the application of the fiber mesh enable the autoclaved aerated concrete building block to perform well in multiple directions, providing a high-performance wall material for the construction industry.

[0019] As shown in the attached Figure 1 to the attached Figure 2 figures:
[0020] An anti-cracking autoclaved aerated concrete block provided by the present utility model includes a fiber mesh frame 1, a bottom-sealing casting part 2, a batch-casting part 3, a top-sealing casting part 4, and a distributed fiber mesh 5. Both the fiber mesh frame 1 and the distributed fiber mesh 5 are arranged inside the bottom-sealing casting part 2, the batch-casting part 3, and the top-sealing casting part 4. A plurality of distributed fiber meshes 5 are provided. The fiber mesh frame 1, the bottom-sealing casting part 2, the batch-casting part 3, the top-sealing casting part 4, and the distributed fiber mesh 5 together construct a square block that performs well in multiple directions.
[0021] Embodiment 1:
[0022] Specifically, in the production process of autoclaved aerated concrete blocks, a specific reinforcement structure is carefully designed to significantly improve its tear resistance. This structure mainly includes a fiber mesh frame 1 and a distributed fiber mesh 5, which are closely combined with the casting part of the block to form a stable and high-performance whole.
[0023] Specifically, the fiber mesh frame 1 is a square mesh frame structure made by carefully weaving fiber filaments on twelve struts. These twelve struts together construct a complete square frame, providing important structural support for the building block. It is worth noting that the fiber mesh frame 1 does not penetrate the bottom sealing casting part 2 and the top sealing casting part 4, but maintains a certain distance, which is not less than two centimeters thick, ensuring a tight bond between the mesh frame and the casting part, and at the same time providing additional protection for the building block.
[0024] Specifically, the distributed fiber mesh 5 is another reinforcement structure, which is a mesh structure woven from square fiber filaments. Several distributed fiber meshes 5 are vertically distributed between each batch casting part 3, as well as between the bottom sealing casting part 2 or the top sealing casting part 4 and the batch casting part 3. This distribution method ensures that the building block is uniformly reinforced on multiple levels, further improving its tear resistance.
[0025] Specifically, during the casting process, the thicknesses of the bottom sealing casting part 2 and the top sealing casting part 4 are the same, and their thicknesses are greater than or equal to the thickness of the batch casting part 3. This design ensures that the building block has sufficient strength at both the top and the bottom, and at the same time makes the connection between each casting part closer, further improving the overall performance of the building block.
[0026] Embodiment 2:
[0027] During the production process of autoclaved aerated concrete building blocks, an innovative casting method is adopted to significantly improve the tear strength of the building blocks. This method first involves preferentially casting a bottom sealing casting part 2 with a thickness less than 10 cm to provide a solid and stable base for the subsequent insertion of the fiber mesh frame 1. This step ensures that the fiber mesh frame 1 can be evenly and firmly embedded in the bottom sealing casting part 2, thus establishing a solid reinforcement structure.
[0028] Subsequently, the square fiber mesh frame 1 is inserted into the bottom sealing casting part 2 as a strengthening material. The fiber mesh frame 1 can significantly improve the tear resistance of the building block. When the building block is subjected to external forces, the fiber mesh frame 1 can bear part of the tensile force, effectively delaying the formation and expansion of cracks. To further enhance the performance of the building block, the method of placing the distributed fiber mesh 5 layer by layer is adopted during the casting process. After casting a certain amount of slurry, a new layer of distributed fiber mesh 5 is placed on its surface, and finally it is encapsulated by casting the top sealing casting part 4, and the casting of the building block is completed. This layer-by-layer strengthening method ensures that the building block has excellent tear resistance as a whole.
[0029] Embodiment 3:
[0030] It should be noted that the distributed fiber mesh 5 located inside the square fiber mesh frame 1 further enhances the bonding force inside the building block, making the entire building block structure more compact and stable. The presence of the distributed fiber mesh 5 enables the building block to consume energy through the stretching and breaking of the fibers when subjected to external forces, thereby significantly improving the tear resistance strength of the building block. The square fiber mesh frame 1 and the distributed fiber mesh 5 inside it jointly form a three-dimensional reinforcement network, making the building block have excellent tear resistance performance in multiple directions.
[0031] In addition, the optimization of this pouring process also plays a key role. By first pouring the low-thickness bottom-sealing pouring part 2 and placing the distributed fiber mesh 5 layer by layer, the tight combination between the distributed fiber mesh 5 and the slurry is ensured, avoiding the voids and defects between the distributed fiber mesh 5 and the slurry, thus significantly improving the overall strength of the building block.
[0032] In summary, by adopting the pouring method of first pouring a low-thickness slurry and placing the fiber mesh layer by layer, the tear resistance strength of the autoclaved aerated concrete building block can be significantly improved. The success of this method benefits from the reinforcement effect of the fiber mesh and the optimization of the pouring process, enabling the building block to better resist tearing and damage when subjected to external forces. Therefore, in practical engineering, it is strongly recommended to adopt this innovative pouring method to enhance the tear resistance performance of the autoclaved aerated concrete building block.
[0033] Using the technical solution of the present utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
