[0021] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0022] A silicon-aluminum composite high-aluminum poly light brick according to an embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. Example

[0023] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a silicon-aluminum composite high-aluminum poly-light brick, comprising a high-aluminum poly-light brick main body 1, wherein an alumina fiber layer 2 and an aluminum silicate fiber layer 3 are arranged inside the high-aluminum poly-light brick main body 1, wherein a longitudinal carbon fiber layer 4 is arranged inside the high-aluminum poly-light brick main body 1, and the carbon fiber layer 4 is located between the alumina fiber layer 2 and the aluminum silicate fiber layer 3, and a vertical channel 7 for pouring concrete is provided on the top of the high-aluminum poly-light brick main body 1, and two transverse channels 8 connected to the vertical channel 7 are provided on one side wall of the high-aluminum poly-light brick main body 1. When two high-aluminum poly-light brick main bodies 1 are spliced, concrete poured at the port of the vertical channel 7 flows through the transverse channel 8 to the joint of the two high-aluminum poly-light brick main bodies 1, so as to ensure that the connection between the two high-aluminum poly-light brick main bodies 1 is more firmly established.

[0024] Furthermore, one end surface of the alumina fiber layer 2 is provided with a plurality of first through holes 21, and one end surface of the aluminum silicate fiber layer 3 is provided with a plurality of second through holes 31. One end surface of the carbon fiber layer 4 is provided with a plurality of third through holes 41.

[0025] It should be noted that firstly, high-quality high-alumina bauxite clinker, alumina powder, aluminum silicate raw materials, carbon fiber, alumina fiber, aluminum silicate fiber and necessary binders and additives are selected. The carbon fiber needs to be pre-treated to ensure its stability and corrosion resistance at high temperatures.

[0026] The high-alumina bauxite clinker, alumina powder, and aluminum silicate raw materials are mixed in proportion, and appropriate amounts of binders and additives are added, and the mixture is ground into a uniform and fine slurry by a ball mill. The slurry is injected into the mold using mold forming technology, and the position of the longitudinal carbon fiber layer 4 is preset to ensure that it is fully wrapped by the slurry, while space for the alumina fiber layer 2 and the aluminum silicate fiber layer 3 is reserved at the designated position.

[0027] Before the main material is initially solidified, the pre-prepared alumina fiber layer 2 and aluminum silicate fiber layer 3 are embedded to ensure that one end surface of the two is flush with the surface of the main material. Using precision drilling equipment, a first through hole 21, a second through hole 31 and a third through hole 41 are respectively opened on one end surface of the alumina fiber layer 2, the aluminum silicate fiber layer 3 and the carbon fiber layer 4 to increase the air permeability of the material and the fluidity when pouring concrete.

[0028] The first connection groove 5 is designed and cut on the top of the high-aluminum poly light brick body 1, and the second positioning pieces 10 are installed on both sides of the bottom. The second connection groove 6 is opened on one side wall of the high-aluminum poly light brick body 1, and the first positioning piece 9 is installed. The other side is provided with a matching interface to achieve horizontal connection between bricks, and then the vertical channel 7 and the horizontal channel 8 are cut on the high-aluminum poly light brick body 1 again. Finally, the whole structure is placed in a constant temperature and humidity environment at a suitable temperature for curing treatment to ensure the formation of the brick body.

[0029] When using the brick, special high temperature resistant concrete is poured into the vertical channel 7 on the top of the high alumina poly light brick body 1, and the horizontal channel 8 is used to make the concrete flow to the joints between the bricks to enhance the connection strength between the bricks during installation and use.

[0030] In an optional embodiment: the top of the high-aluminum poly light brick body 1 is provided with a first connection groove 5, and the vertical channel 7 is provided at the bottom of the first connection groove 5. Two second positioning members 10 that are engaged with the first connection groove 5 are fixedly connected to both sides of the bottom of the high-aluminum poly light brick body 1.

[0031] It should be noted that by providing a first connection groove 5 on the top of the high-aluminum polylight brick body 1 and installing second positioning members 10 on both sides of the bottom, it is ensured that it can be clamped and positioned with adjacent bricks stacked on top of each other.

[0032] In an optional embodiment: a second connection groove 6 is provided on one side of the high-aluminum poly light brick body 1, and the transverse channel 8 is provided at one end of the second connection groove 6. Two first positioning members 9 that are engaged with the second connection groove 6 are fixedly connected to the other side of the high-aluminum poly light brick body 1.

[0033] It should be noted that by setting a second connecting groove 6 on one side of the high-aluminum polylight brick body 1, two first positioning members 9 are provided on the other side to be clamped with the second connecting groove 6. The first positioning members 9 are matched and clamped with the second connecting groove 6 to achieve horizontal connection between bricks.

[0034] Working principle: The first connection groove 5 opened on the top of the brick body and the second positioning pieces 10 on both sides of the bottom realize the precise docking and fixation of the bricks in the vertical direction. The design of the second connection groove 6 and the first positioning piece 9 on the side wall ensures a tight connection in the horizontal direction and enhances the stability of the overall structure. High temperature resistant concrete is poured in the vertical channel 7. The concrete flows into the joints of the bricks through the guidance of the horizontal channel 8. After solidification, a strong mechanical lock is formed, which significantly improves the pressure resistance and heat resistance of the joint area.
