Overflowing mortar is collected by the extension plates, preventing contamination of the wall surface.

Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an auxiliary device for controlling masonry mortar joints. Background Technology

[0002] Currently, the thickness of mortar joints in masonry construction is controlled based on the experience of the workers. Due to the varying skill levels of the workers, the thickness of the mortar joints and the fullness of the mortar are significantly different from the design effect, thus affecting the appearance quality and construction quality.

[0003] Differences in the operating techniques of different workers can lead to a deviation of 5-10mm in the thickness of the mortar joints, exceeding the ±2mm standard required by the "Code for Acceptance of Construction Quality of Masonry Structures" (GB50203-2011), resulting in uneven stress on the wall and affecting structural safety.

[0004] While some auxiliary tools exist in existing technologies, such as simple straightedges or thickness gauges, none have formed a systematic solution. For example, the "masonry mortar joint thickness control ruler" disclosed in CN201721823456.7 can only measure the thickness at a single point and cannot simultaneously control the mortar spreading and fullness. In practical applications, it still requires multiple manual adjustments and fails to fundamentally solve the problem of quality fluctuation. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for controlling masonry mortar joints in order to solve the above-mentioned problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides an auxiliary device for controlling masonry mortar joints, including an L-shaped frame. The bottom and side of the L-shaped frame are respectively provided with a filling groove one and a filling groove two. Both sides of the L-shaped frame in the length direction are fixedly connected to an extension plate for receiving concrete.

[0008] A leveling mechanism is fixedly connected to the extension plate for leveling concrete in filling groove one and filling groove two.

[0009] Using the above-mentioned auxiliary device for controlling masonry mortar joints, the L-shaped frame is placed at the location where masonry blocks need to be laid, and concrete is placed in filling groove one and filling groove two. Then, the concrete is leveled in filling groove one and filling groove two by a leveling mechanism. After the concrete is leveled, the L-shaped frame is removed, and the next block can be laid. The thickness of the mortar layer can be controlled by filling groove one and filling groove two, which improves the aesthetics of the wall.

[0010] Preferably, the L-shaped frame is fixedly connected to a handle on both the top and side.

[0011] Preferably, guide plates are fixedly connected to both sides of the bottom of the L-shaped frame and both sides of the vertical surface of the L-shaped frame for fitting against both sides of the wall.

[0012] Preferably, the extension plate is U-shaped, with one vertical plate corresponding to the facade of the L-shaped frame, and the upper side of the extension plate is flush with the upper side of the base frame of the L-shaped frame.

[0013] Preferably, the leveling mechanism includes two guide rods, which are fixedly connected to the extension plate along the length of the L-shaped frame. A connecting component is slidably connected to the guide rod, and a mounting frame is vertically slidably connected between the two connecting components. A roller is rotatably connected to the mounting frame.

[0014] Preferably, the roller contacts the L-shaped frame, and the length of the roller is not less than the width of filling groove one and filling groove two.

[0015] Preferably, a handle is fixedly connected to the mounting bracket.

[0016] Preferably, the connecting assembly includes a sliding sleeve, on which the guide rod is slidably connected, and on which a slider is fixedly connected.

[0017] Preferably, the mounting bracket has vertical slots on both sides, and the two sliders are slidably connected to the two vertical slots respectively.

[0018] Preferably, the surface of the roller is provided with a ceramic coating.

[0019] The beneficial effects are:

[0020] The thickness of the mortar joint can be stably controlled by the filling groove one at the bottom of the L-shaped frame and the filling groove two on the side, which greatly improves the accuracy compared with traditional manual construction. The extension plate and the guide plate form a closed paving space. The mortar is laterally constrained in the filling groove. During the paving process, the mortar filling rate inside the mortar joint can be improved. The extension plate can catch the overflowing mortar to avoid contaminating the wall surface.
