[0002] As a building material, aerated block brick has a development history of several decades in China. At present, it is widely used in the field of masonry structure in China, mainly due to its low density, good thermal insulation performance, convenient construction, fast construction speed and other advantages. Therefore, it is widely used in housing construction projects. Through technical innovation, the strength, durability and thermal insulation performance of aerated block bricks have been further improved, and some products have also added fireproofing, waterproofing and other functions. Due to the gradual recognition of the advantages of aerated block bricks by the market, the market acceptance is continuously improving, and it is not only used in new buildings, but also applied in old house renovation.

[0003] The national and local standardization organizations have formulated relevant standards and specifications for the production and application of aerated block bricks, improving the quality of aerated block bricks. However, there are still many problems in the construction process of aerated block, such as: aerated block masonry mortar joint is not full, mortar joint is not straight, and there are false joints and other problems.

[0004] During the aerated block masonry, it is particularly important to evenly spread the masonry mortar on the aerated block. The traditional masonry brick masonry mortar is spread by using a "brick knife" to manually level, and then the upper layer of blocks is placed and the flatness and perpendicularity are adjusted by knocking, which is prone to uneven mortar leading to uneven mortar joints. Moreover, a lot of mortar falls to the ground during the mortar spreading process, causing waste of labor and materials. Ensuring the quality and speed of mortar spreading can improve the masonry speed of brick masonry and ensure the quality of brick masonry.

[0005] Therefore, a device that can effectively improve the quality and speed of mortar spreading and ensure the thickness quality of the mortar joint is needed during mortar spreading. SUMMARY

During the mortar spreading process, a connecting rod is provided to control the thickness of the mortar and ensure the uniformity of the mortar thickness during the construction process. The edge beam and positioning member are provided to ensure the straightness of the mortar joint and reduce the generation of mortar falling to the ground. The overall fixed connection structure avoids the influence of deformation caused by long-term use or storage and transportation on the masonry process.

[0007] Another purpose of the utility model is to form a bevel design at the edge of the spread mortar through the setting of the positioning member, reduce the generation of mortar falling to the ground, and make the mortar joint more beautiful after placing the upper layer of blocks, reduce the construction difficulty of the pointing process, and avoid the waste of materials.

[0008] The device can leave two grooves for placing steel bars during mortar laying, improve the integrity of the building body, improve the anti-seismic capability, and reduce the risk of cracking and collapse of the building body after the cutting block is placed.

[0018] Preferably, the positioning member (12) is of an inverted trapezoidal structure.

[0019] The short side of the trapezoidal positioning member (12) is a contact surface with the mortar of the building body (4) and provides support for the device for ensuring the mortar joint quality of a brick masonry; the long side of the trapezoidal positioning member (12) is a contact surface connected with the connecting rod (2); the inclined side of the trapezoidal positioning member (12) is a contact surface in contact with the mortar and limiting the generation of falling mortar; and the height of the trapezoidal positioning member (12) is a side of the L-shaped edge beam, which is longitudinally extended to be attached to the side surface of the building body (4).

[0020] Preferably, a rectangular frame structure is formed between the edge beam (1) and the connecting rod (2).

[0021] Preferably, a grouting space (5) is formed between the connecting rod (2), the scraping teeth (21), and the inclined surface of the positioning member (12).

[0022] The thickness of the connecting rod (2) and the height of the inverted trapezoid of the positioning member (12) control the thickness of the spread mortar.

[0023] Preferably, the squeegee (21) is in the shape of an inverted triangle or a cylinder or a diamond, which is used to draw several grooves on the surface of the spread mortar.
