Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to a masonry mortar joint control system and method. Background Technology

[0002] Masonry work, as a crucial component of building construction, significantly impacts the building's insulation, thermal insulation, and sound insulation properties through the quality of its mortar joints. Traditional masonry construction requires string lines in both the horizontal and vertical directions to control the thickness of horizontal and vertical mortar joints. This method is cumbersome, often relying on feel, visual inspection, and experience; the lack of scientific and effective control methods leads to uneven mortar joint thickness, affecting the overall quality of the masonry project and directly impacting the building's appearance and actual measurements. Furthermore, problems with mortar joints are often difficult to repair, sometimes necessitating complete rebuilding, resulting in rework, economic losses, and increased construction costs. Therefore, proposing a mortar joint control device is of great significance.

[0003] To address the aforementioned technical issues, some existing technologies employ two parallel longitudinal sliding tracks. During mortar pouring, these tracks are slid horizontally across the wall, and a trowel is used to smooth the surface, quickly forming horizontal mortar joints of uniform thickness. This saves construction time while ensuring the uniformity of mortar joint thickness, improving the appearance and overall quality of the finished wall. Other technologies utilize special mortar joint molds. Mortar is poured into the upper cavity of the mold while it is moved horizontally along the construction direction, ensuring the mortar joints are straight, uniform in size, and full and smooth. Still others use infrared light as both vertical and horizontal mortar joint indicator lines, facilitating worker observation of the control positions of both horizontal and vertical mortar joints and improving the control accuracy of both.

[0004] However, the above technical solution still has the following technical problems:

[0005] (1) The mold outlet is prone to blockage and is narrow and difficult to clean.

[0006] (2) The mold is only suitable for low and medium parts and has a limited range of applications.

[0007] (3) The device is inconvenient to install and still needs to be verified before use. Summary of the Invention

A method for controlling masonry mortar joints, characterized in that, The application of the masonry mortar joint control system as described in claim 5 includes the following steps: S1: Assemble all components of the masonry mortar joint control system on the construction site; S2: Adjust the height of the telescopic outrigger (32) according to the construction requirements of the working surface and set up the sand-laying and smoothing unit (1) above the masonry to be worked; S3: Pour sand into the mortar inlet (15). After the mortar surface slightly exceeds the trowel (13), move the sand spreading and troweling unit (1) slowly in the mortar spreading direction through the movable telescopic support unit (3) to ensure that the mortar is evenly spread between the two horizontal guide rails (21) of the detachable guide rail shaping unit (2). When it moves to the vertical mortar joint of the masonry, pause appropriately and continue to move in the mortar spreading direction to ensure that the vertical mortar joint is filled with mortar. S4: After completing the mortar joint laying of this layer of masonry, the sand-laying and smoothing unit (1) is raised to the height of the next working surface by adjusting the telescopic support leg (32), masonry blocks are placed under the sand-laying and smoothing unit (1), and then the detachable guide rail shaping unit (2) is placed on the masonry blocks, and step S3 is repeated. S5: After the mortar joint laying in this area is completed, if it is necessary to transfer the masonry mortar joint control system to the next work area, the sand laying and smoothing unit (1) can be kept connected to the movable telescopic support unit (3), and the fixed foot brake can be released to push it to the next work area, and steps S2-S4 can be repeated; if the work is finished, the sand laying and smoothing unit (1) can be removed from the horizontal connecting rod (31) of the movable telescopic support unit (3) through the detachable connector, and the sand laying and smoothing unit (1), the detachable guide rail shaping unit (2), and the movable telescopic support unit (3) can be put back into the warehouse together.
