Description

Technical Field

[0001] This utility model relates to the field of concrete block technology, specifically a high-strength fly ash autoclaved aerated concrete block. Background Technology

[0002] Concrete blocks are a common building material, made from a mixture of raw materials such as cement, sand, and aggregates. They are block-shaped components formed through vibration, pouring, and curing. Fly ash autoclaved aerated concrete (AAC) blocks are a special type of concrete block. Fly ash and chemical foaming agents are added during their production process. They are made through processes such as batching, mixing, pouring, static curing, cutting, and high-pressure autoclaving. Fly ash is a byproduct of coal combustion and is a gray fine powder that can be used to replace part of the cement. The addition of chemical foaming agents can generate air bubbles. These air bubbles can reduce the density of the concrete and form a porous structure during the curing process, improving the lightweight, thermal insulation, and sound insulation properties of the blocks.

[0003] For example, a high-strength autoclaved aerated concrete block with application number CN202320087230.0 includes a block body with reinforcing ribs fixed inside. Movable grooves are provided on both sides of the block body, and connecting blocks are horizontally arranged inside the movable grooves. A lifting rod is fixedly provided at the top of the connecting block, with its upper end extending to the top of the block body and fixedly equipped with a lifting ring. An insert rod is fixedly provided at the bottom of the connecting block, with its lower end extending to the bottom of the block body. Slots are provided on both sides of the top of the block body. This invention has high structural strength, extending the service life of the block body, and also features a hoisting structure for easy lifting of the block body to a high position.

[0004] However, in actual use, when pouring the blocks, several reinforcing ribs are placed vertically or horizontally inside them. Since the reinforcing ribs are not fixed together, there will be a large difference in strength in different parts of the block, and the pressure cannot be evenly distributed in each part, thus affecting the overall hardness. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-strength fly ash autoclaved aerated concrete block, which solves the problem that in actual use, when several reinforcing ribs are placed vertically or horizontally inside the block during casting, and because the reinforcing ribs are not fixed together, the strength of different parts of the block will vary greatly, and the pressure cannot be evenly distributed to each part, thus affecting the overall hardness.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength fly ash autoclaved aerated concrete block, comprising a concrete block, the outer wall of which is provided with a rigid layer, and a reinforcing structure installed between the rigid layer and the concrete block. The reinforcing structure includes: multiple fixing frames, all embedded in the inner wall of the concrete block; multiple connecting pipes, each fixedly connected to the outer wall of the fixing frame; a fixing rod, fixedly connected between two fixing frames; and a fixing net, disposed on the outer wall of the fixing frame and fixedly connected to the outer wall of the concrete block. The connecting pipes install multiple fixing frames, the fixing rods ensure the stability of the fixing frames during fixing, and the fixing net wraps around the fixing frames, increasing the compressive strength of the concrete block.

[0007] Preferably, the inner wall of the fixed net is equipped with a support structure, the support structure including: a support rod, disposed on the inner wall of the fixed net; and two top plates, respectively fixedly connected to the two ends of the support rod and attached to the inner wall of the fixed net; wherein, through the cooperation of the support rod and the top plate, the compressive strength of the concrete block and the hard layer is increased.

[0008] Preferably, the outer wall of the fixing net is equipped with a moisture-proof layer, and the outer wall of the moisture-proof layer is fixedly connected to the inner wall of the rigid layer.

[0009] Preferably, a trapezoidal groove is formed on the top of the rigid layer, a trapezoidal block is fixedly connected to the bottom of the rigid layer, a limit post is provided on both sides of the trapezoidal block, and a limit groove is formed on both sides of the top of the rigid layer.

[0010] Preferably, a strip is fixedly connected to one side of the outer wall of the rigid layer, and a slot is provided on the other side of the rigid layer.

[0011] Beneficial effects

[0012] This invention provides a high-strength fly ash autoclaved aerated concrete (AAC) block. It offers the following advantages: The high-strength fly ash AAC block utilizes a combination of a fixing frame, connecting pipes, and fixing rods. The fixing frame is connected via the connecting pipes, and the upper and lower fixing frames are tightened by the fixing rods. After assembly, a fixing net is used to wrap the block, which is then placed inside the pouring concrete block. Once the concrete has cooled and solidified, the block is secured, thereby increasing its hardness. Furthermore, the fixing rods and nets ensure a tighter connection between the fixing frame and the fixing rods, thus distributing the pressure across the concrete block and increasing its strength.

[0013] By using trapezoidal blocks, trapezoidal grooves, and limiting posts, when stacking blocks, the limiting posts at the top of the blocks are inserted into the limiting grooves, aligning the upper block with the lower block. After the blocks are released, the trapezoidal blocks are locked in the trapezoidal grooves under the action of gravity, connecting the two blocks and making it convenient for workers to use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In actual use, when casting blocks, several reinforcing ribs are placed vertically or horizontally inside them. Since the reinforcing ribs are not fixed together, there will be a large difference in strength in different parts of the block, and the pressure cannot be evenly distributed in each part, thus affecting the overall hardness.

[0021] In view of this, the present invention provides a high-strength fly ash autoclaved aerated concrete block, which solves the problem that in actual use, when several reinforcing ribs are placed vertically or horizontally inside the block during casting, and because the reinforcing ribs are not fixed together, the strength of different parts of the block will vary greatly, and the pressure cannot be evenly distributed to each part, thus affecting the overall hardness.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a high-strength fly ash autoclaved aerated concrete block includes a concrete block 1. The concrete block 1 is a porous concrete product made from fly ash, lime, cement, gypsum, slag, etc., as main raw materials, with the addition of appropriate amounts of foaming agent, regulator, and bubble stabilizer. It is produced through processes such as batching and mixing, pouring, static curing, cutting, and high-pressure autoclaving. The outer wall of the concrete block 1 is provided with a hard layer 11, which is composed of a large amount of aggregate and cement to increase its strength. A reinforcing structure 2 is installed between the hard layer 11 and the concrete block 1. The reinforcing structure 2 includes: a fixing frame 21, which is provided in multiple locations. The components are: an inner wall embedded in the concrete block 1; several connecting pipes 22, each fixedly connected to the outer wall of the fixing frame 21; a fixing rod 23, fixedly connected between two fixing frames 21; and a fixing net 24, set on the outer wall of the fixing frame 21 and fixedly connected to the outer wall of the concrete block 1. The fixing net 24 is made of iron and has ductility, ensuring stability when fixing the fixing frame 21. The connecting pipes 22 install multiple fixing frames 21, the fixing rods 23 ensure the stability of the fixing frame 21 during fixing, and the fixing net 24 wraps around the fixing frame 21, increasing the compressive strength of the concrete block 1.

[0024] In the specific implementation process, it is worth noting that, with the cooperation of the fixing frame 21, the connecting pipe 22 and the fixing rod 23, the fixing frame 21 is connected together by the connecting pipe 22, and the upper and lower fixing frames 21 are tightened by the fixing rod 23. After assembly, it is wrapped with the fixing net 24 and placed inside the concrete block 1 being poured. After the concrete cools and solidifies, it is fixed, thereby increasing the hardness of the block. Under the action of the fixing rod 23 and the fixing net 24, the fixing frame 21 and the fixing rod 23 are more closely connected, thereby distributing the pressure borne by the concrete block at each position and increasing the strength of the concrete block 1.

[0025] Furthermore, a support structure 3 is installed on the inner wall of the fixed net 24. The support structure 3 includes: a support rod 31, which is set on the inner wall of the fixed net 24; and two top plates 32, which are respectively fixedly connected to the two ends of the support rod 31 and attached to the inner wall of the fixed net 24. The cooperation between the support rod 31 and the top plate 32 increases the compressive strength of the concrete block 1 and the hard layer 11.

[0026] In the specific implementation process, it is worth noting that when stacking concrete blocks 1, the support rods 31 and the top plate 32 increase the pressure that the concrete blocks 1 can withstand, further increasing the hardness of the concrete.

[0027] Furthermore, a moisture-proof layer 18 is installed on the outer wall of the fixed net 24, and the outer wall of the moisture-proof layer 18 is fixedly connected to the inner wall of the rigid layer 11.

[0028] In the specific implementation process, it is worth noting that the moisture barrier 18 is composed of a vapor barrier membrane, a thermal insulation layer, and a waterproof and breathable membrane. These material layers work together to slow down the rate at which indoor moisture is discharged into the thermal insulation layer, effectively preventing the formation of condensation, and quickly dissipating moisture from the thermal insulation layer, thereby protecting the thermal performance of the building structure.

[0029] Specifically, when using this high-strength fly ash autoclaved aerated concrete block, during the pouring of concrete block 1, the fixing frame 21 is connected together using the connecting pipe 22, and the upper and lower fixing frames 21 are tightened by the fixing rod 23. After assembly, it is wrapped with the fixing net 24 and placed inside the concrete block 1 being poured. After the concrete cools and solidifies, it is fixed, thereby increasing the hardness of the block. Under the action of the fixing rod 23 and the fixing net 24, the fixing frame 21 and the fixing rod 23 are more tightly connected, thereby distributing the pressure borne by the concrete block at each position, increasing the strength of the concrete block 1, and preventing the hardness of the concrete block 1 from decreasing. In addition, the support rod 31 and the top plate 32 support the upper and lower parts of the concrete block 1, further increasing the hardness of the concrete block 1. Moreover, the moisture-proof layer 18 can prevent moisture from corroding the fixing frame 21 and other parts inside the concrete, thus affecting the hardness of the concrete block 1.

[0030] Example 2: From Figure 1-4 It can be seen that a trapezoidal groove 15 is provided on the top of the rigid layer 11, a trapezoidal block 14 is fixedly connected to the bottom of the rigid layer 11, a limit post 16 is provided on both sides of the trapezoidal block 14, and a limit groove 17 is provided on both sides of the top of the rigid layer 11.

[0031] In the specific implementation process, it is worth noting that, with the cooperation of trapezoidal block 14, trapezoidal groove 15 and limiting post 16, when the blocks are stacked, the limiting post 16 at the top of the block is inserted into the limiting groove 17, so that the upper block is aligned with the lower block. After the blocks are released, under the action of gravity, trapezoidal block 14 is stuck in trapezoidal groove 15, connecting the two blocks, which is convenient for workers to use.

[0032] Furthermore, a strip plate 12 is fixedly connected to one side of the outer wall of the rigid layer 11, and a slot 13 is provided on the other side of the rigid layer 11.

[0033] In the specific implementation process, it is worth noting that when assembling the blocks on both sides with the cooperation of strip 12 and slot 13, strip 12 is inserted into slot 13 on the outer wall of rigid layer 11 to connect multiple blocks.

[0034] Specifically, based on the above embodiments, when assembling the blocks, strips 12 and slots 13 are used to connect multiple blocks. When stacking them up and down, limiting posts 16 and limiting grooves 17 are used to align the concrete blocks 1 and fix them together under the action of trapezoidal blocks 14, which facilitates the operation of workers.

Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
