Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a composite partition wall made of autoclaved aerated concrete blocks. Background Technology
[0002] Autoclaved aerated concrete (AAC) blocks are porous concrete products made from fly ash, lime, cement, gypsum, slag, and other main raw materials, with the addition of appropriate amounts of foaming agents, regulators, and bubble stabilizers. They are produced through processes such as batching and mixing, pouring, static curing, cutting, and high-pressure autoclaving. AAC blocks are a new type of building material that is lightweight, porous, has good thermal insulation, fire resistance, can be nailed, sawed, and planed, and has a certain degree of earthquake resistance. They are widely used in wall infill.
[0003] However, existing autoclaved aerated concrete blocks are installed by aligning adjacent blocks and using interlocking components. This method of stacking blocks can easily concentrate the pressure on the brick joints, which can easily lead to wall cracking. Utility Model Content
[0004] The purpose of this utility model is to provide a composite partition wall made of autoclaved aerated concrete blocks, which aims to solve the technical problem that the existing method of stacking blocks can easily concentrate the pressure on the brick joints, leading to wall cracking.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an autoclaved aerated concrete block composite partition wall, comprising a first masonry layer and a second masonry layer, wherein the first masonry layer and the second masonry layer are alternately distributed and gradually stacked to form a wall;
[0006] The first masonry layer comprises several first blocks arranged sequentially along the horizontal direction. Each first block has a slot on one of its two sides, and the two slots are symmetrically distributed. The second masonry layer comprises several second blocks arranged sequentially along the horizontal direction. Each second block has four lugs, and the four lugs are centrally symmetrically distributed. The lugs of the second blocks can be inserted into the slots of the first blocks, so that the gaps between two adjacent first blocks are staggered from the gaps between two adjacent second blocks.
[0007] Optionally, the slot is located in the middle of the first block.
[0008] Optionally, the four hooks are located at the corners of the second block.
[0009] Optionally, the card slot is trapezoidal in shape, and the first included angle between the side wall and the bottom wall of the card slot is 90°-120°.
[0010] Optionally, the lug has an inclined surface, and the second included angle between the inclined surface and the surface of the second block is 90°-115°.
[0011] Optionally, the first height of the first block is equal to the second height of the second block.
[0012] Optionally, the height of the ear loop is slightly greater than the depth of the slot.
[0013] Optionally, the depth of the slot is one-quarter to one-third of the first height of the first block.
[0014] Optionally, the ear height of the ear loop is one-fifth to one-third of the second height of the second block.
[0015] The beneficial effects of the autoclaved aerated concrete block composite partition wall provided in this embodiment of the invention, compared with the prior art, are as follows:
[0016] This utility model discloses a composite partition wall made of autoclaved aerated concrete blocks. A first layer of masonry is formed by arranging several first blocks horizontally in sequence, and a second layer of masonry is formed by arranging several second blocks horizontally in sequence. By setting grooves in the first blocks and lugs in the second blocks, the lugs of the second blocks are inserted into the grooves of the first blocks during the overlapping process. This not only ensures that the gaps between adjacent first blocks are staggered with the gaps between adjacent second blocks, thus preventing cracking due to misaligned gaps, but also effectively strengthens the bond between the first and second masonry layers, resulting in a more robust and longer-lasting wall.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0031] like Figures 1-5 As shown, the autoclaved aerated concrete (AAC) block composite partition wall provided in this embodiment of the present invention will now be described. The AAC block composite partition wall includes a first masonry layer 100 and a second masonry layer 200, which are alternately distributed and gradually stacked to form a wall.
[0032] The first masonry layer 100 includes several first blocks 10 arranged sequentially along the horizontal direction. Each of the two sides of a first block 10 is provided with a slot 11, and the two slots 11 are symmetrically distributed. The second masonry layer 200 includes several second blocks 20 arranged sequentially along the horizontal direction. Each second block 20 is provided with four lugs 21, and the four lugs 21 are centrally symmetrically distributed. The lugs 21 of the second block 20 can be inserted into the slots 11 of the first block 10, so that the gap between two adjacent first blocks 10 is staggered from the gap between two adjacent second blocks 20.
[0033] Compared with the prior art, the autoclaved aerated concrete block composite partition wall provided by this utility model embodiment has the following advantages: First, a number of first blocks 10 are arranged sequentially along the horizontal direction to form a first wall layer 100, and second, a number of second blocks 20 are arranged sequentially along the horizontal direction to form a second wall layer 200. Furthermore, by providing slots 11 in the first blocks 10 and lugs 21 in the second blocks 20, during the overlapping of the first and second blocks 10, the lugs 21 of the second blocks 20 are inserted into the slots 11 of the first blocks 10. This not only ensures that the gaps between adjacent first blocks 10 and adjacent second blocks 20 are staggered, thus avoiding cracking of the wall due to misaligned gaps, but also effectively strengthens the bond between the first wall layer 100 and the second wall layer 200, resulting in a stronger and more robust wall with a longer service life.
[0034] Specifically, the first block 10 is connected to the first block 10, the second block 20 is connected to the second block 20, and the first block 10 is connected to the second block 20 by conventional connecting material 30, which will not be described in detail here.
[0035] In one embodiment, such as Figures 1-4 As shown, the slot 11 is located in the middle of the first block 10, and the four lugs 21 are located at the corners of the second block 20. Two lugs 21 can be inserted into each slot 11, so that the two lugs 21 of two adjacent second blocks 20 can be inserted into one slot 11 at the same time. This ensures that the first block 10 and the second block 20 are staggered and layered, thereby ensuring that the gap between the first masonry layer 100 and the second masonry layer 200 is misaligned, reducing the risk of wall cracking.
[0036] In one embodiment, such as Figure 3 As shown, the slot 11 is a trapezoidal shape with a large opening at the outer end. The first included angle C1 between the side wall and the bottom wall of the slot 11 is 90°-120°, which makes it easy for the hanging lug 21 of the second block 20 to be inserted into the slot 11, and the wall can be completed very quickly.
[0037] In one embodiment, such as Figure 4 As shown, the ear 21 has an inclined surface, and the second included angle C2 between the inclined surface and the surface of the second block 20 is 90°-115°. By setting the inclined surface on the ear 21, it is easier for the ear 21 to engage with the side wall of the slot 11 when it is inserted into the slot 11, which improves the stability of the fit. Furthermore, the inclined angle of the ear 21 is smaller than the angle of the side wall of the slot 11, which allows the ear 21 to be inserted into the slot 11 better and maintain a stable fit, resulting in a better performance.
[0038] In one embodiment, such as Figures 3-4 As shown, the first height H1 of the first block 10 is equal to the second height H2 of the second block 20, so that the wall can be neatly built layer by layer, and the wall is aesthetically pleasing.
[0039] In one embodiment, the ear height S2 of the lug 21 is slightly greater than the groove depth S1 of the slot 11. The groove depth S1 of the slot 11 is one-quarter to one-third of the first height H1 of the first block 10. The ear height S2 of the lug 21 is one-fifth to one-third of the second height H2 of the second block 20. This ensures the structural stability of each first masonry layer 100 and second masonry layer 200, thereby ensuring the overall wall is stable and has a high seismic resistance level.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
