Description

Technical Field

[0001] This utility model relates to the field of block technology, and in particular to a carbon-fixed concrete hollow block. Background Technology

[0002] The existing method for producing hollow concrete blocks involves first mixing raw materials such as aggregates, sand, and cement to form concrete, then pressing it into shape using molds and curing it. During curing, carbon dioxide is injected, allowing it to react with calcium hydroxide in the concrete, thus achieving carbon sequestration and reducing carbon emissions. However, existing hollow blocks are generally rectangular in shape with several rectangular holes inside, resulting in a relatively small surface area and limited reaction area with carbon dioxide, leading to low carbon sequestration efficiency. Furthermore, when using hollow blocks to build walls, adjacent blocks are independent of each other, making it difficult for beginners to control spacing and align them, increasing the difficulty of building and reducing efficiency and quality. Utility Model Content

[0003] The purpose of this utility model is to provide a carbon-fixing concrete hollow block. By using connecting bodies and adding structural cavities, the total surface area of ​​the hollow block can be increased, thereby improving the carbon fixation efficiency. The interlocking of the connecting bodies facilitates the alignment of adjacent hollow blocks, thus making the wall construction easier.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A carbon-fixed concrete hollow block includes an integrally formed intermediate body and two mating connectors disposed at the left and right ends of the intermediate body, wherein the two mating connectors are disposed at the center of the intermediate body.

[0006] The mating connector is stepped; a stepped groove is formed between the mating connector and the intermediate body, and the stepped groove mates with the mating connector.

[0007] The above technical solution allows hollow blocks to be spliced ​​along their length by setting two centrally symmetrical connecting bodies. This also increases the surface area of ​​the hollow blocks, facilitating the reaction between carbon dioxide and concrete during production and improving carbon sequestration.

[0008] The present invention is further configured such that: the mating connecting body includes a boss, an intermediate step surface, a lowest step surface and a bottom base surface, the lowest step surface is connected to the intermediate body, and the bottom base surface is flush with one side outer wall of the intermediate body;

[0009] The plane of the boss on the left side of the mating connector is flush with the lowest step surface of the mating connector on the right side;

[0010] The middle stepped surface of the left mating connector is flush with the middle stepped surface of the right mating connector.

[0011] With the above technical solution, when two adjacent hollow blocks are connected, the left protrusion of one block can be abutted against the lowest step surface of the right block of the other block, and the two mating and connecting intermediate step surfaces are also abutted together, which facilitates the alignment of the two adjacent hollow blocks, so that multiple hollow blocks can still be in a straight line after being spliced ​​together.

[0012] The present invention is further configured such that the width L of the lowest step surface is greater than the width l of the boss.

[0013] The difference in Ll is between 10 and 20 mm.

[0014] With the above technical solution, the width of the boss is slightly smaller than the width of the lowest step surface, which makes it easier for the boss to be inserted into the lowest step surface. The gap can be filled with concrete, thereby improving the bonding ability between two adjacent hollow blocks.

[0015] The present invention is further configured such that each of the intermediate body and the mating connecting body has a structural cavity formed therein; by setting the structural cavity, the surface area of ​​the hollow block can be further increased, which further facilitates the carbon fixation work; at the same time, lightweighting is achieved while ensuring the strength of the hollow block.

[0016] The present invention is further configured such that grooves are formed on the upper and lower surfaces of the intermediate body and the mating connector.

[0017] By setting grooves, the bonding ability between two adjacent hollow blocks can be increased. The concrete used for bonding can enter the grooves, thereby improving the bonding force.

[0018] The outstanding effect of this utility model is:

[0019] Compared with existing technologies, by combining connectors and adding structural cavities, the total surface area of ​​hollow blocks can be increased, the contact area for reaction with carbon dioxide can be increased, and the carbon fixation efficiency can be improved.

[0020] By using the interlocking mechanism between the connecting bodies, it is easy to align adjacent hollow blocks and control the gaps, thus facilitating the bricklaying work and reducing the requirements for bricklaying workers. Attached Figure Description

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] The following is for reference Figures 1 to 5 The present invention will be described as follows:

[0030] A type of carbon-fixed concrete hollow block, such as Figure 1 As shown, it includes an integrally formed intermediate body 1 and two mating connecting bodies 2 disposed at the left and right ends of the intermediate body 1. The two mating connecting bodies 2 are disposed at the center of the intermediate body 1.

[0031] The mating connector 2 is stepped; a stepped groove 100 is formed between the mating connector 2 and the intermediate body 1, and the stepped groove 100 mates with the mating connector 2.

[0032] By setting two centrally symmetrical connecting bodies, hollow blocks can be spliced ​​together along the length direction, which can increase the surface area of ​​the hollow block, facilitate the reaction of carbon dioxide with concrete during the production process, and improve the carbon sequestration effect.

[0033] like Figure 2 As shown, the mating connector 2 in this embodiment includes a boss 201, an intermediate step surface 202, a lowest step surface 203, and a bottom base surface 204. The lowest step surface 203 is connected to the intermediate body 1, and the bottom base surface 204 is flush with one side outer wall of the intermediate body 1.

[0034] The plane of the boss 201 of the left mating connector 2 is flush with the lowest step surface 203 of the right mating connector 2.

[0035] The middle step surface 202 of the left mating connector 2 and the middle step surface 202 of the right mating connector 2 are flush.

[0036] When two adjacent hollow blocks are connected, the left-side protrusion of one block can rest against the lowest step surface of the right side of the other block, and the two mating step surfaces also fit together, which facilitates the alignment of the two adjacent hollow blocks, so that multiple hollow blocks can still be in a straight line after being spliced ​​together.

[0037] The width L of the lowest step surface 203 is greater than the width l of the boss 201; the difference between L and l is 10 to 20 mm.

[0038] The width of the boss is slightly smaller than the width of the lowest step surface to facilitate insertion of the boss into the lowest step surface. The gap can be filled with concrete, thereby improving the bonding strength between adjacent hollow blocks. A schematic diagram of the linear splicing of multiple hollow blocks is attached to the instruction manual. Figure 3 As shown,

[0039] like Figure 1 As shown, the intermediate body 1 and the mating connecting body 2 of this embodiment each have a structural cavity 101 formed inside; by setting the structural cavity, the surface area of ​​the hollow block can be further increased, which further facilitates the carbon fixation work; at the same time, lightweighting is achieved while ensuring the strength of the hollow block.

[0040] like Figure 1 As shown, grooves 102 are formed on the upper and lower surfaces of the intermediate body 1 and the mating connector 2 in this embodiment.

[0041] By setting grooves, the bonding ability between two adjacent hollow blocks can be increased. The concrete used for bonding can enter the grooves, thereby improving the bonding force.

[0042] By incorporating grooves, the bonding strength between adjacent hollow blocks can be increased. The concrete used for bonding can enter the grooves, thereby enhancing the bonding force. A schematic diagram of the vertical stacking of these hollow blocks is shown below. Figure 4 , Figure 5 As shown.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
