Description

Technical Field

[0001] This application claims the priority of Chinese Patent Application No. 2024218964636 filed on August 7, 2024, and the entire content of the above specification is a reference for this application.

[0002] This application relates to the field of construction tools, and specifically relates to a tool for controlling mortar joints in masonry. Background Art

[0003] A mortar joint refers to the mortar layer between two bricks during wall masonry, that is, the seam formed by applying mortar between bricks during wall construction. The control of mortar joint quality has always been one of the key points in the construction industry because the composition and structure within the mortar joint are prone to generating internal stress, which affects the mechanical properties of the wall. Additionally, the mortar joint is likely to reduce the average heat transfer resistance of the wall and increase the heat load of the wall. Traditional mortar joint construction mainly uses the "one brick, one shovel of mortar, and one kneading and squeezing" method by manual labor, which has a strong dependence on the craftsmanship level and implementation experience of workers. Problems such as too long mortar spreading length between masonry units, uneven thickness, and high mortar material loss rate are likely to occur, and phenomena such as transparent joints, false joints, and mortar joint thickness exceeding the positive deviation allowed by the current specifications are also likely to occur.

[0004] In the technical solution of Patent CN219045282 U, a tool for controlling mortar joints in masonry is provided, which includes a clamping plate, a screw rod, a positioning frame, a guide rod, a limiting block, and a handle. This tool jointly limits the width of the mortar joint in masonry through the positioning frame and the limiting block, and at the same time, through the guide strip on the clamping plate, it facilitates the sliding connection of the positioning frame. A handle is fixedly installed at the bottom of the outer side wall of the clamping plate. The tool for controlling mortar joints in masonry provided by this technical solution can effectively improve the quality of mortar joints and can quickly adjust the height of the positioning frame according to the thickness of the mortar joint, which helps to improve construction efficiency.

[0005] Regarding the above related technologies, the inventor found that there are at least the following problems in this technology: The device is provided with a limiting block, which has requirements for the width of the overall mortar joint in masonry. The distance between the clamping plates cannot exceed the limiting block, restricting the applicable range during actual use. On the other hand, the structure of this device is complex, which is not conducive to use during the specific construction process. Summary of the Invention

[0040] Embodiment 1

[0041] As Figures 1-3 shown, this embodiment provides a mortar joint control device for masonry, which can be divided into a positioning structure 10 and a control structure 20.

[0042] The positioning structure includes a bracket 11, and the bracket 11 includes two spacing control rods 14 that are parallel to each other and a guide rod 15 that is perpendicularly connected thereto. This bracket is for supporting the entire device to facilitate subsequent specific operations thereon. In order to fix the entire positioning structure 11 on the corresponding masonry, a fixing member 12 is provided at the lower end of the guide rod 15. By providing the fixing member, the entire device can be moved on the masonry according to the construction direction of the masonry mortar laying and fixed at the desired position. The fixing member 12 is a hollow triangular prism. The hollow structure can reduce the construction cost and facilitate the subsequent arc argon welding. The triangular prism structure is beneficial to the stability of fixing the entire device on the wall surface.

[0043] In order to be able to flexibly adjust the width of the masonry mortar joint according to different actual situations, the control device 20 includes a limit rod 21 mounted on the two spacing control rods 14. The limit rod 21 can slide back and forth along the spacing control rod 14 according to the different widths of the masonry mortar joint to adjust its position on the bracket 11, so that when laying the masonry mortar, the thickness of the mortar joint and the length of each mortar laying can be effectively controlled, thereby adjusting the width of the masonry mortar joint 27 and improving the construction quality. In order to effectively fix the sliding of the limit rod 21 on the bracket 11 and avoid the occurrence of unstable phenomena, a number of first positioning holes 13 are provided on the two spacing control rods 14 of the bracket 11, and second positioning holes 23 are provided at both ends of the limit rod 21. The first positioning holes and the second positioning holes 23 are fixedly connected by a connecting member 22. According to different cross-sections, different first positioning holes 13 and fixed second positioning holes 23 are adjusted relative to each other, and the connecting member 22 passes through the first positioning hole 13 and the second positioning hole 23 to tightly connect the limit rod 21 to the bracket 11.

[0044] The control structure 20 further includes a connecting member 22. The connecting member 22 includes a screw rod 24, a nut 25, and a triangular member 28 provided at the bottom of the screw rod 25 for stable fixing. The triangular member 28 is a solid triangular prism structure, which is convenient for plugging and fixing on the corresponding masonry, avoiding the sliding of the device involved in this utility model, and playing a role of stability and shock absorption. In order to prevent loosening between the nut and the screw rod, the connecting member 22 further includes a gasket 26 provided between the nut 24 and the screw rod 25. This gasket can reduce the possibility of the connecting member falling off and causing the device to be unstable, and can effectively increase the stability of this designed device. At the same time, the triangular member is a solid triangular prism and is made of stainless steel, ensuring its mechanical strength, not being easily deformed or rusted, and can effectively increase the service life of this device.

[0045] The specific use process of the embodiment is as follows:

[0046] The operator places the bracket 11 on the masonry working surface, and the fixing member 12 under the positioning structure 10 is clamped against the masonry. According to the width of different masonry mortar joints 27, the second positioning holes 23 on the limit rod 21 are aligned with different first positioning holes 13 on the two spacing control rods 14. Through the connecting member 22, the limit rod 21 is fixed to the bracket 11 through the triangular fixing member 22. The screw 25 passes through the first positioning hole 13 and the second positioning hole 23, with a nut 24 connected to the upper end and a triangular member 28 in the shape of a solid triangular prism connected to the lower end. In order to prevent loosening between the nut 24 and the screw 25, a gasket 26 is provided between the nut 24 and the spacing control rod 14. The operator lays mortar within the fixed range according to the design drawings and current specifications, compacts, smooths, and makes the thickness of the mortar between the masonries uniform. After completing the laying of mortar for the masonry, loosen the fixing member and move it left and right by pushing and pulling.
