Description

Technical Field

[0001] The utility model relates to the technical field of concrete blocks, in particular to a filled autoclaved aerated concrete block. Background Art

[0002] Currently, my country's building energy consumption accounts for 27% of total societal energy consumption, making it a major energy consumer. Wall energy consumption accounts for approximately 60% of this energy consumption. my country's buildings are designed to last 50 to 100 years, and over this long service life, they consume significant amounts of energy.

[0003] Autoclaved aerated concrete blocks are favored by the construction industry due to their simple construction, light weight, and long service life, leading to their widespread application. To improve the thermal insulation performance of autoclaved aerated concrete blocks, an insulation layer is usually added to the blocks. However, if the insulation layer is too small, it will not be effective. If the insulation layer is too large, the autoclaved aerated concrete blocks on both sides of the insulation layer will separate from the insulation layer, thus affecting the overall strength. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a filled autoclaved aerated concrete building block.

[0005] The present invention is achieved through the following technical solution: a filled autoclaved aerated concrete block comprising a block body and an insulation board fully embedded in the block body, and further comprising a plurality of connecting rods that pass through the insulation board and extend into the block body at both ends, each end of the connecting rods being fixed with a plurality of barbs. In this solution, the barbs are provided at both ends of the connecting rods, thereby tightening the block body on both sides of the insulation board through the connecting rods, thereby preventing separation of the insulation board and the block body connection surface and improving the overall strength.

[0006] As an optimization, a plurality of protrusions are provided in the middle of the connecting rod. The protrusions in this solution increase the friction between the connecting rod and the insulation board, preventing the two from moving axially.

[0007] As an optimization, the connecting rod is provided with a plurality of annular protrusions at both ends, and the barbs are provided on the annular protrusions. The annular protrusions in this solution further improve the connection strength between the connecting rod and the block, while increasing the diameter position of the barb root, thereby improving the connection strength of the barb.

[0008] As an optimization, a convex strip is provided on one long side of the block, and a groove adapted to the convex strip is provided on the other long side of the block. In this solution, when adjacent blocks are butted up and down, positioning is achieved through the convex strip and the groove.

[0009] As an optimization, the end face of the connecting rod is provided with a threaded hole, so that the end of the connecting rod can be connected by a bolt to achieve connection with external components.

[0010] As an optimization, the thickness of the insulation board is 0.5-0.8 times the thickness of the block, which improves the insulation effect while ensuring the strength of the block itself.

[0011] As an optimization, the length of the connecting rod is 0.7-0.9 times the thickness of the block to achieve the best connection effect.

[0012] The beneficial effects of the present invention are as follows: the present invention provides a filled autoclaved aerated concrete block, by arranging barbs at both ends of the connecting rod, so that the blocks on both sides of the insulation board are tightened by the connecting rod, thereby preventing the connection surface of the insulation board and the block from separating, thereby improving the overall strength of the autoclaved aerated concrete block, ensuring the thermal insulation performance while improving the overall strength of the autoclaved aerated concrete block.

[0020] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0021] like Figures 1 to 5 As shown, the present invention is a filled autoclaved aerated concrete block comprising a block 1 and an insulation board 2 completely embedded in the block 1. The insulation board 2 is a foam glass insulation board, and the block 1 is made of autoclaved aerated concrete. The thickness of the insulation board 2 is 0.5-0.8 times the thickness of the block 1. The length of the insulation board 2 is consistent with the length of the block 1. In this embodiment, the distance between the edge of the insulation board 2 and the edge of the block 1 is 3-15 cm, so that the insulation board is completely embedded in the block 1.

[0022] A convex strip 4 is provided on one long side of the block 1, and a groove 5 adapted to the convex strip 4 is provided on the other long side of the block 1. When adjacent blocks are butted up and down, positioning is achieved by the convex strip and the groove.

[0023] It also includes several connecting rods 3, and one or more connecting rods 3 can be set. When one connecting rod 3 is set, the connecting rod passes through the middle position of the insulation board 2. When multiple connecting rods 3 are set, they are evenly distributed on the insulation board 2.

[0024] The connecting rod 3 passes through the insulation board 2 and is arranged vertically, with the length of the exposed ends being the same, and both ends extending into the block 1. In this embodiment, the length of the connecting rod 3 is 0.7-0.9 times the thickness of the block 1.

[0025] The end face of the connecting rod 3 is provided with a threaded hole, so that the end of the connecting rod can be connected to the end of the connecting rod by bolts to achieve connection with external components.

[0026] In order to improve the bite force between the connecting rod 3 and the block, a plurality of annular protrusions are provided at both ends of the connecting rod 3. In this embodiment, 4-6 annular protrusions are provided at each end and are evenly distributed at the same end.

[0027] The annular protrusion is provided with barbs 7, and each annular protrusion 8 is provided with 3-7 barbs 7 and is evenly distributed in the circumferential direction.

[0028] To improve the engagement between the insulation board and the connecting rod, a plurality of protrusions 6 are provided in the middle of the connecting rod 3. Multiple protrusions 6 are provided along the length and circumference of the connecting rod 3 to improve engagement with the insulation board. The protrusions 6 have a height of 1-3 mm and a diameter of 0.5-2 mm.

[0029] The connecting rod 3 can be a metal rod or a plastic rod, and the barbs 7 , the annular protrusions 8 and the bumps 6 are all integrally formed on the connecting rod 3 .

[0030] The processing method of the utility model is as follows: during processing, first prepare insulation boards and connecting rods of appropriate sizes, pass the connecting rods through the insulation boards, and prevent the connecting rods from axial movement by the provided convex points 6. Then, the insulation boards and the connecting rods are put into a steaming box together, slurry is injected, and steaming is carried out to form autoclaved aerated concrete blocks.
