Description

Technical Field

[0001] The utility model relates to the technical field of autoclaved aerated concrete blocks, in particular to an autoclaved aerated concrete block for green building projects with good connection strength. Background Art

[0002] Autoclaved aerated concrete blocks are a kind of porous concrete products made of fly ash, lime, cement, gypsum, slag and other main raw materials, with appropriate amount of gas generating agent, regulator, bubble stabilizer, and are made through processes such as batching, mixing, pouring, static stopping, cutting and high-pressure steaming. The unit volume weight of autoclaved aerated concrete blocks is one-third of that of clay bricks, the thermal insulation performance is 3-4 times that of clay bricks, the sound insulation performance is 2 times that of clay bricks, the anti-permeability performance is more than one times that of clay bricks, and the fire resistance performance is 6-8 times that of reinforced concrete. They are widely used in green building projects.

[0003] At present, when autoclaved aerated concrete blocks are used, adjacent autoclaved aerated concrete blocks are generally connected by applying concrete mortar on the outside. In the actual operation process, it is necessary to ensure the alignment of the upper and lower autoclaved aerated concrete blocks by pulling wires, which is time-consuming and highly dependent on the workers' work experience, and is inconvenient for manual operation. At the same time, the upper and lower autoclaved aerated concrete blocks are only connected by concrete mortar, and the connection method is also relatively single, which reduces the connection strength and is not conducive to the construction of green building projects. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an autoclaved aerated concrete block for green building engineering with good connection strength, which solves the problems raised in the above-mentioned background technology.

[0006] Optionally, evenly distributed card slots are symmetrically opened on both sides of the groove, and the card slots cooperate with the card blocks to achieve the limitation of the upper and lower concrete blocks, which is convenient for workers to operate, and an expansion slot is opened at the bottom of the groove.

[0007] Optionally, the insertion of the protrusion and the groove can facilitate the positioning of the upper and lower concrete blocks, avoid the need for wire calibration, and improve work efficiency. The two sides of the protrusion are symmetrically connected with evenly distributed card blocks, the density of the card blocks is the same as that of the card slot, and the width of the card block is smaller than the width of the card slot. A connecting groove is provided at the bottom of the protrusion, which can increase the contact area between the concrete mortar and the groove and the protrusion, thereby improving the stability of the building.

[0008] Optionally, there are multiple pillars evenly connected to the bottom of the protrusion, and the overall height of the pillars and the protrusion is greater than the depth of the groove, which can provide filling space for concrete mortar and also avoid the problem of errors easily caused by manual control of mortar thickness, thereby improving work efficiency and quality.

[0011] 2.

At the same time, a plurality of pillars 4 are connected to the bottom of the protrusion 3. When the pillars 4 are in contact with the inside of the groove 2, there is a gap between the contact surfaces of adjacent blocks, so that when the groove 2 and the protrusion 3 are connected up and down, corresponding space can be provided for filling the concrete mortar, avoiding the problem that the mortar thickness needs to be manually controlled when connecting traditional autoclaved aerated concrete blocks, improving the installation and connection efficiency and quality of autoclaved aerated concrete blocks, and facilitating the construction of green building projects.

[0021] To sum up, the autoclaved aerated concrete block for green building projects with good connection strength is connected and fixed so that the protrusion 3 is located on the bottom surface, and the bottom of the protrusion 3 is paved with concrete mortar, and then the concrete mortar is filled above the groove 2.
