Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a mortar spreading tool for masonry construction. Background Technology

[0002] In masonry construction, mortar application is a crucial step in determining the strength and stability of the masonry structure. For a long time, masonry work relied on manual labor: workers had to use trowels to apply mortar layer by layer to the surface of the blocks, controlling the thickness and uniformity of the mortar distribution through experience. The speed of manual mortar application was limited by the worker's physical strength and skill, and it was difficult to precisely control the mortar thickness. Applying too much mortar would cause it to be squeezed out of the masonry, resulting in waste; applying too little mortar would lead to uneven bonding between the blocks, easily causing localized hollow areas, cracks, and even structural leaks.

[0003] Therefore, existing technologies have developed tools for quickly spreading mortar, such as the wall masonry mortar spreading tool disclosed in patent CN211818151U, which includes a mortar storage box, an inclined plate, and a toothed plate. The mortar storage box is rectangular, with an open top and a discharge port on the front side. The toothed plate matches and is fixedly installed at the discharge port, with several evenly distributed teeth at its bottom. In use, the mortar in the storage box slides down the inclined plate under gravity and then slides out from the discharge port onto the masonry. However, this technical solution has two drawbacks. First, the mortar spreading tool lacks a limiting device for the masonry, making it difficult to ensure that the mortar is spread in a straight line on the masonry. Second, even if the mortar spreading tool is stationary on the masonry, the mortar will automatically squeeze outwards, and if the tool's movement speed is not properly controlled, uneven mortar spreading can easily occur.

[0004] For example, patent CN221546449U discloses a novel mortar-laying tool for wall construction. This technical solution adds lateral guide wheels to the side plate to ensure that the tool can move in a straight line along the wall, and sets a horizontal guide wheel on the rear side of the tool to significantly reduce the friction between the tool and the wall. However, when applying this technical solution to mortar with poor fluidity, due to its rapid movement, the mortar is easily blocked at the outlet, resulting in insufficient mortar and leakage, which affects the efficiency of masonry construction. Utility Model Content

[0005] This invention aims to overcome the problems of low grouting efficiency, poor grouting effect, and easy clogging of existing grouting tools, and proposes a grouting tool for masonry construction to overcome the above-mentioned defects.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A mortar spreading tool for masonry construction includes a receiving trough for holding mortar, with a discharge plate inclined on one side of the receiving trough; the bottom of the receiving trough is hollowed out and is provided with a bottom support assembly for supporting the receiving trough;

[0008] The base support assembly includes a support portion for contacting the top of the masonry, and a limiting portion perpendicular to the support portion for contacting the side of the masonry; the discharge plate has a discharge port on the side near the support portion.

[0009] In traditional masonry construction, workers need to apply mortar to the next surface after each section of masonry is laid, a repetitive process that severely impacts efficiency. Currently available mortar application tools lack a mechanism to limit movement relative to the masonry, making it difficult for workers to ensure the tool moves in a straight line. Furthermore, if the tool moves too quickly, or if the mortar is highly viscous, the mortar can clog the outlet.

[0010] Therefore, this invention incorporates an inclined discharge plate and a perforated receiving groove into the traditional mortar spreading tool. In use, the mortar spreading tool is placed directly on the masonry, and sufficient mortar is added to the receiving groove. The mortar at the bottom directly contacts the masonry. Pulling the tool then forces the mortar onto the masonry under the pressure of the inclined discharge plate, leaving a uniform layer. Furthermore, this invention features a base support assembly at the bottom of the receiving groove, adapted to the width of the masonry. On one hand, the support portion of the base support assembly not only supports the receiving groove but also reduces the size of the perforated bottom, preventing mortar from flowing out of the masonry. On the other hand, the limiting portion of the base support assembly contacts the side of the masonry, ensuring the mortar spreading tool can only move along the direction of the masonry. Finally, the base support assembly significantly increases the contact area between the mortar spreading tool and the masonry. Even at high speeds, the natural vibrations generated during tool movement produce high-frequency micro-vibrations in the receiving groove, preventing mortar blockage at the discharge port and improving the uniformity of mortar application.

[0011] Preferably, the limiting part further includes an extension component for abutting against the side of the masonry. Since the base support component needs to be adapted to the width of the masonry, in order to adapt to more usage scenarios, by setting the extension component on the limiting part, the mortar spreading tool of this utility model can also be used directly when facing narrow masonry.

[0012] As a further preferred embodiment, the extension component is an adjustable-length telescopic bolt. In use, it can be adapted to narrower masonry sections by screwing in the telescopic bolt.

[0013] Preferably, a friction layer is provided on the side of the support that contacts the top of the masonry. To further improve the effect of the high-frequency micro-vibration, a friction layer is provided on the support, which has uneven micro-protrusions, thereby increasing the vibration generated when the grouting tool of this invention moves on the surface of the masonry.

[0014] Preferably, an adjustment device is provided between the discharge plate and the receiving tank to adjust the size of the discharge port.

[0015] As a further preferred embodiment, the adjusting device includes a mounting plate fixed on the receiving groove, and the discharge plate is provided with adjusting holes at positions corresponding to the mounting plate; it also includes adjusting bolts provided on the adjusting holes to connect the discharge plate and the mounting plate.

[0016] As a further preferred embodiment, the discharge plate is provided with a horizontal plate for adjusting the size of the discharge port.

[0017] As a further preferred embodiment, the cross plate is fixed to the discharge plate by the adjusting bolts.

[0018] Preferably, the discharge port includes two or more concave teeth. The concave teeth can extrude strips of mortar, which can enhance the friction between masonry elements, saving mortar and improving overall stability.

[0019] Preferably, the receiving slot is provided with a handle for easy gripping.

[0020] Therefore, this utility model has the following beneficial effects:

[0021] (1) The present invention reduces the size of the bottom hole of the receiving groove by setting the bottom support component, so that the mortar at the edge is not easy to flow out of the masonry. At the same time, the vibration generated by the friction of the bottom support component effectively prevents the mortar from clogging.

[0022] (2) This utility model can adapt to masonry of various widths through a variety of adjustment devices of the preferred scheme, and can quickly change the grout output. In practice, it saves a lot of time for changing tools and improves construction efficiency.

[0023] (3) This utility model has a simple structure and integrates the functions of material storage, material discharge and coating, which simplifies the operation process, reduces labor intensity and construction cost, and is suitable for application and promotion in practice.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0032] Example 1:

[0033] like Figure 1 As shown, the main body of the masonry mortar spreading tool in this embodiment is a rectangular steel receiving trough 1, with a discharge plate 2 installed at an angle on one side, making the discharge plate 2 form an acute angle with the masonry plane. "U"-shaped handles are provided on the receiving troughs 1 on both sides of the discharge plate 2, making it convenient for construction workers to grip the device and move it backward. A discharge port 3 for discharging mortar is located on the side of the discharge plate 2 closest to the masonry. Figure 2 As shown, the bottom of the receiving tank 1 is provided with a bottom support assembly 10, and the side plate of the receiving tank 1 extends downward to form a limiting part 12. A fixed metal strip perpendicular to the side plate forms a support part 11, and the support parts 11 are hollowed out so that mortar can pass through directly.

[0034] like Figure 3 , 4As shown, in this embodiment, the discharge plate 2 is connected to the receiving tank 1 via an adjustment device 20. A long strip-shaped mounting plate 21 is welded outwards onto the side wall of the receiving tank 1. Each mounting plate 21 has a pre-drilled long strip-shaped adjustment hole 22, and a corresponding adjustment hole 22 of the same size is drilled on the discharge plate 2. Adjustment bolts 23 pass through the mounting plate 21 and the discharge plate 2 to achieve adjustable fixing of the discharge plate 2. Figure 4 As shown, when a larger amount of mortar is needed, loosen the adjusting bolt 23 and pull the discharge plate 2 upwards, so that a certain distance is created between the concave teeth 5 below the mounting plate 2 and the support part 11. This gap, together with the concave teeth 5, forms the discharge port 3. Then tighten the adjusting bolt 23 set on the elongated adjusting hole 22 to fix the discharge plate 2 and complete the adjustment of this embodiment. Before use, the width of the receiving groove 1 needs to be determined according to the actual needs to ensure that the limiting part 12 can just contact the masonry. When using, first place the receiving groove 1 on the masonry 7 that needs to be built, ensuring that the support part 11 of the bottom support assembly 10 directly contacts the top surface of the masonry 7, while the limiting part 12 contacts the side of the masonry 7. Then add sufficient mortar into the receiving groove 1. Part of the mortar directly covers the masonry through the hollow between the support parts 11, and the other part of the mortar remains on the support parts 11 to prevent it from flowing out of the masonry. At this point, the construction worker can hold handle 6 and pull the device backward. The mortar in the receiving tank 1 is squeezed out from the discharge port 3 under the pressure of the inclined discharge plate 2. Due to the setting of the bottom support assembly 10, a slight vibration will be generated during the pulling of the device, preventing the mortar from clogging at the discharge port 3. Finally, a strip of mortar will be left on the top surface of the masonry 7 through which the device passes. After the mortar is spread to cover a row of masonry, other masonry can be laid on the mortar.

[0035] Example 2:

[0036] In practice, it was found that Example 1 has two inconveniences: First, because the limiting part must be in close contact with the masonry, frequent adjustments to the mortar spreading tool are required when dealing with masonry of different widths, affecting construction efficiency; second, due to the concave tooth design, the minimum mortar discharge volume is limited by the concave teeth, making it difficult to further adjust to smaller mortar discharge volumes. Therefore, as... Figure 5 , 6As shown, the difference between the masonry grouting tool in this embodiment and that in embodiment 1 is that, firstly, two telescopic bolts 13 are provided at each side limiting part 12. When the width of the masonry to be built is less than the width of the receiving groove 1, the telescopic bolts 13 on both sides can be screwed inward so that the telescopic bolts 13 abut against the side of the masonry 7, thereby achieving the limiting function. Secondly, since the contact area between the telescopic bolts 13 and the masonry 7 is small, in order to enhance the vibration of this device during movement, this embodiment provides a friction layer 14 below the support part 11. The friction layer 14 has uneven micro-protrusions, so that the grouting tool of this embodiment can generate greater vibration during movement. Finally, this embodiment adds a horizontal plate 4 above the concave teeth 5. The horizontal plate 4 is also provided with corresponding adjustment holes 22. In this way, the mounting plate 21, the discharge plate 2, and the horizontal plate 4 can be fixed simultaneously by using a longer adjusting bolt 23. When it is necessary to further reduce the size of the discharge port 3, the adjusting bolt 23 can be loosened, the horizontal plate 4 can be moved downwards a certain distance to block part of the concave tooth 5, and the adjusting bolt 23 can be tightened again to further reduce the size of the discharge port 3, so that the slurry spreading tool of this embodiment can adapt to more application scenarios.

[0037] The embodiments of this specification have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical applications, or technological improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
