Abstract
Description
Technical Field
[0001] This utility model relates to the field of masonry construction technology, specifically a mortar thickness control tool for controlling the thickness of vertical and horizontal mortar joints in masonry projects. Background Technology
[0002] When constructing masonry walls for building construction, it is usually necessary to set up a bricklaying gauge, vertical lines, and horizontal lines. The horizontal line is raised layer by layer as the number of masonry courses increases. The standardized "one trowel of mortar, one brick, one pressing" three-in-one masonry method is usually used to control the quality of masonry. However, due to differences in workers' masonry skills, personal habits, and quality concepts, this method is prone to causing common quality problems such as uneven mortar joints, insufficient mortar, blind joints, and false joints. Utility Model Content
[0003] To address the common quality problems in masonry construction mentioned above, this utility model provides a tool for controlling the thickness of masonry mortar. This tool is simple in composition, easy to use, and highly efficient, and can simultaneously control the thickness of masonry mortar in both vertical and horizontal directions.
[0004] The technical solution adopted by this utility model to achieve the above-mentioned objective is as follows: a mortar thickness control tool for masonry, comprising two L-shaped templates connected by an M10 screw assembly. The long side of the L-shaped template is placed horizontally, and the ends of the long and short sides are respectively provided with rectangular ears. In each pair of opposite rectangular ears, one has a bolt hole adapted to the M10 screw assembly, and the other is fixedly connected to the unthreaded end of the M10 screw assembly. The threaded end of the M10 screw assembly passes through the bolt hole and is locked by an alignment nut. A retaining edge is provided on the inner side of the L-shaped template.
[0005] The M10 screw assembly includes an adjusting screw and a positioning nut threaded onto the adjusting screw. The unthreaded end of the adjusting screw is welded to a rectangular lug, and the threaded end passes through the bolt hole and is locked by the positioning nut.
[0006] The rectangular ears consist of two sets: one set located at the end of the long side of the L-shaped template is vertically arranged, and the other set located at the end of the short side of the L-shaped template is horizontally arranged.
[0007] The inner surface of the L-shaped template is coated with a tungsten carbide wear-resistant layer, which improves the surface wear resistance and service life of the L-shaped template.
[0008] The width of the gusset is 5mm and the thickness is 10mm.
[0009] This utility model uses aligning nuts on both sides for adjustment and tightening, ensuring overall stability of the tool. The clamp width is fixed at 5mm and the thickness at 10mm, thereby controlling the mortar thickness and ensuring consistent thickness of longitudinal and transverse mortar joints, improving the quality and overall aesthetics of the masonry structure. This utility model provides a mortar thickness control tool that can effectively control both vertical and transverse mortar thickness during masonry construction, improving construction quality, reducing operating costs, and is easy to operate.

[0014] The technical solution of this utility model will now be described in detail and completely with reference to the accompanying drawings and embodiments.
[0015] Example
[0016] like Figure 1 The tool for controlling the thickness of masonry mortar shown includes two L-shaped templates 2 connected by an M10 screw assembly 1. The long side of the L-shaped template 2 is placed horizontally, and the ends of the long and short sides are respectively provided with rectangular ears 4. In each pair of opposite rectangular ears 4, one has a bolt hole adapted to the M10 screw assembly 1, and the other is fixedly connected to the unthreaded end of the M10 screw assembly 1. The threaded end of the M10 screw assembly 1 passes through the bolt hole and is locked by an alignment nut 6. The inner side of the L-shaped template 2 is provided with a retaining rim 3.
[0017] like Figure 2 As shown, the M10 screw assembly 1 includes an adjusting screw 5 and a positioning nut 6 threadedly connected to the adjusting screw 5. The unthreaded end of the adjusting screw 5 is welded to a rectangular lug 4, and the threaded end passes through the bolt hole and is locked by the positioning nut 6.
[0018] The rectangular ears 4 include two sets: one set located at the end of the long side of the L-shaped template 2 is vertically arranged, and the other set located at the end of the short side of the L-shaped template 2 is horizontally arranged.
[0019] The inner surface of the L-shaped template 2 is coated with a tungsten carbide wear-resistant layer, which improves the surface wear resistance and service life of the L-shaped template.
[0020] The gusset 3 has a width of 5mm and a thickness of 10mm.
[0021] This utility model uses the two-sided alignment nuts 6 to adjust and tighten, making the tool as a whole stable; the clamp 3 is 5mm wide and 10mm thick, which controls the mortar thickness, so that the thickness of the longitudinal and transverse mortar joints is consistent, improving the quality of the masonry and the overall aesthetics.
[0022] like Figure 3 As shown, the specific operating steps of the masonry mortar thickness control tool of this utility model are as follows:
[0023] First, before use, adjust the alignment nuts 6 according to the wall thickness so that the L-shaped templates 2 on both sides of the tool fit against the two sides of the wall, and the clamps 3 on both sides rest on the upper side of the wall and tighten the nuts. The thickness of the clamps 3 is the thickness of the mortar joint.
[0024] Secondly, after the first layer and the first block of the second layer of masonry are completed, place the tool at the position of the second block of the second layer of masonry, invert the mortar, and use a mortar scraper to scrape the vertical and horizontal mortar along the L-shaped template 2.
[0025] Finally, drag the tool horizontally to the next masonry position, place the blocks, and repeat the previous step to build the next masonry after the masonry is completed.
[0026] The embodiments of this utility model have been disclosed above, but they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
