Description
Technical Field
[0001] This utility model relates to the field of masonry technology, and in particular to a mortar joint pointing device for masonry. Background Technology
[0002] Mortar joints refer to the gaps formed between masonry blocks after they are bonded together with mortar in a masonry structure. They are divided into horizontal mortar joints and vertical mortar joints. After the masonry is completed, the mortar joints usually need to be grouted to make them more beautiful and smooth, while also improving the integrity and waterproof performance of the wall.
[0003] When grouting masonry joints, a slightly curved rod is usually used to move inside the joint to adjust the mortar. Traditional grouting devices have a fixed surface shape, which cannot simultaneously grout grooves and flat joints. In addition, removing excess mortar from the brick wall surface requires the rod to be vertically pressed against the wall and moved to scrape off the mortar, resulting in low practicality and flexibility in the use of grouting devices. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of traditional grouting devices having a fixed surface shape, which cannot simultaneously grout grooves and flat joints, and requiring the rod to be vertically attached to the wall and moved to scrape off the mortar when removing excess mortar from the brick wall surface, resulting in low practicality and flexibility in the use of the grouting device. Therefore, a grouting device for masonry joints is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mortar joint grouting device, comprising a handle and a grouting head, wherein the grouting head is fixed to one end of the handle for grouting the mortar joints; the outer surface of the handle has two curved grooves, which are located on the upper and lower sides of the handle respectively, and gripping the curved grooves facilitates control of the handle; one end of the handle is provided with a leveling component for leveling protruding mortar on the wall surface.
[0006] Preferably, the grouting head includes a flat head and a curved head. The outer surface of the flat head is triangular and the beveled side is located on the side of the handle facing downwards. The curved head is fixed at the end of the flat head away from the handle, and the curved surface of the curved head is located on the side of the handle facing downwards.
[0007] The aforementioned components achieve the following effects: When using the grouting device to grout masonry joints, hold the handle on its outer surface and place the thumb and other fingers on the two curved grooves on the outer surface of the handle. When a flat joint is needed, place the beveled side of the flat head against the joint and control the movement of the handle and flat head. The flat head can be used to smooth the joint, or the flat head can be used to lift some mortar and bring it into the joint. Move the flat head to grout. When a grooved joint is needed, hold the handle to further control the tilt of the grouting head, then place one side of the curved head against the joint and pull the curved head to grout the joint. The grouting head, composed of a flat head and a curved head, facilitates the creation of flat or grooved joints according to different needs, improving the practicality of the grouting device.
[0008] Preferably, the grouting head further includes two guide pieces, which are located on both sides of the flat head, and the outer edges of the guide pieces are arc-shaped.
[0009] The effect achieved by the above-mentioned components is that when using the flat end for grouting, the mortar that overflows into the grout joint will enter the surface of the guide plate, and the guide plate will guide the overflowing mortar away from the flat end, thus improving the effect of grouting with the flat end.
[0010] Preferably, a plurality of microgrooves are formed on one side of the guide plate, and the microgrooves are linearly distributed on the outer surface of the guide plate.
[0011] The effect achieved by the above components is that by setting microgrooves, the contact area between the guide plate and the mortar can be reduced, the probability of mortar sticking to the surface of the guide plate can be reduced, and the mortar can be more easily detached from the surface of the guide plate.
[0012] Preferably, a support rod is fixedly connected to the top of the handle, and two inclined rods are fixedly connected to the outer surface of the support rod. The ends of the two inclined rods away from the support rod are respectively fixedly connected to one side of the bending head and one side of the flat head.
[0013] The aforementioned components achieve the following effect: by setting diagonal braces and support rods, the connection between the bent head, flat head, and handle can be reinforced, thereby improving the structural strength of the grouting device.
[0014] Preferably, the inner wall of the bending groove is fixedly connected with a plurality of anti-slip strips, which are made of rubber and are linearly distributed inside the bending groove.
[0015] The effect achieved by the above components is that when gripping the two curved grooves on the outer surface of the handle, the rubber anti-slip strips can increase the friction between the fingers and the inner wall of the curved grooves, making it less likely for the operator to slip when holding the handle.
[0016] Preferably, the scraping assembly includes a rotating shaft and a scraper blade. The scraper blade is mounted on the end of the handle away from the grouting head via the rotating shaft. A torsion spring is provided on the outer surface of the rotating shaft. The torsion spring is installed on the outside of the rotating shaft to limit the rotation angle of the rotating shaft. A protruding rod is fixedly connected to one side of the top end of the scraper blade.
[0017] The effect achieved by the above components is as follows: When using the grouting device, if it is necessary to scrape off excess mortar on the wall surface, you can use your fingers, which are holding the surface of the handle near the scraping component, to push the protruding rod to control the scraper to rotate through the pivot axis to the inside of the handle, so that the angle between the scraper and the handle tends to be perpendicular. Then, place one end of the scraper against the wall surface, hold the handle flat and pull the handle horizontally to scrape off the excess mortar on the wall surface, further improving the practicality of the grouting device. When you release the protruding rod, the torsion spring will return to its original state and drive the pivot axis and scraper to rotate back to the original angle.
[0018] Preferably, an auxiliary groove is provided on one side of the scraper, and the internal shape of the auxiliary groove is arc-shaped.
[0019] The effect achieved by the above-mentioned components is that by setting the arc-shaped auxiliary groove, when the scraper moves to scrape mortar on one side of the wall, the mortar is more likely to enter the arc-shaped auxiliary groove on the surface of the scraper, and is less likely to enter between the scraper and the wall, thus improving the scraper's performance.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] (1) By setting up a grouting head composed of a flat head and a curved head, it is easy to grout flat or grooved joints according to different needs, and the mortar overflowing from the grout joint is discharged through the guide plate. When using the grouting device, the grouting effect is more comprehensive, and the practicality of the grouting device is improved.
[0022] (2) By setting up the leveling component, when it is necessary to scrape off excess mortar on the wall, push the scraper to rotate through the shaft so that the angle between the scraper and the handle tends to be perpendicular and put one end of the scraper against the wall. Then, without changing the way the handle is held, the handle can be moved horizontally and the mortar can be scraped off by the scraper, which further improves the practicality and convenience of the grouting device.

[0028] Example 1, such as Figure 1-2 As shown, a mortar joint grouting device includes a handle 1 and a grouting head 2. The grouting head 2 is fixed to one end of the handle 1 for grouting the mortar joint. Two curved grooves 4 are opened on the outer surface of the handle 1. The two curved grooves 4 are located on the upper and lower sides of the handle 1 respectively. Holding the handle 1 at the curved grooves 4 makes it easy to control the handle 1. One end of the handle 1 is provided with a scraping component 3 for scraping the mortar protruding on the wall surface.
[0029] Reference Figure 2-4 As shown in this embodiment: the grouting head 2 includes a flat head 21 and a curved head 22. The outer surface of the flat head 21 is triangular, and the inclined side is located on the side of the handle 1 facing downwards. The curved head 22 is fixed to the end of the flat head 21 away from the handle 1, and the curved surface of the curved head 22 is located on the side of the handle 1 facing downwards. The grouting head 2 also includes two guide plates 23, which are located on both sides of the flat head 21. The outer edge of the guide plate 23 is arc-shaped. When using the grouting device to grout the mortar joints, hold the handle 1 on its outer surface and place the thumb and other fingers on the two curved grooves 4 on the outer surface of the handle 1. When it is necessary to grout the mortar joints, make the inclined side of the flat head 21 fit against the mortar joint, control the movement of the handle 1 and the flat head 21, and grout the mortar joints through the inclined side of the flat head 21. After smoothing, the mortar overflowing from the mortar joint will enter the surface of the guide plate 23. The guide plate 23 will guide the overflowing mortar away from the flat head 21, improving the grouting effect of the flat head 21. Alternatively, the flat head 21 can be used to pick up some mortar and bring it into the mortar joint. The flat head 21 can be moved to grout. When grouting a groove is required, the handle 1 is held to further control the tilt of the grouting head 2. Then, one side of the curved head 22 is placed against the mortar joint. The curved head 22 is pulled to move and grout the mortar joint. The grouting head 2, composed of the flat head 21 and the curved head 22, makes it easy to grout flat or grooved joints according to different needs. The guide plate 23 will guide the overflowing mortar out of the mortar joint. The grouting effect is more comprehensive when using the grouting device, improving the practicality of the grouting device.
[0030] Reference Figure 2-4As shown in this embodiment: a plurality of microgrooves 24 are formed on one side of the guide plate 23. The microgrooves 24 are linearly distributed on the outer surface of the guide plate 23. By setting the microgrooves 24, the contact area between the guide plate 23 and the mortar can be reduced, the probability of the mortar adhering to the surface of the guide plate 23 can be reduced, and the mortar can be more easily detached from the surface of the guide plate 23. A support rod 25 is fixedly connected to the top of the handle 1. Two inclined rods 26 are fixedly connected to the outer surface of the support rod 25. The ends of the two inclined rods 26 away from the support rod 25 are respectively connected to the bending head 22. One side is fixedly connected to the other side of the flat head 21. By setting the diagonal bar 26 and the support bar 25, the connection between the bending head 22, the flat head 21 and the handle 1 can be reinforced, thereby improving the structural strength of the grouting device. Several anti-slip strips 5 are fixedly connected to the inner wall of the bending groove 4. The anti-slip strips 5 are made of rubber and are linearly distributed inside the bending groove 4. When the handle 1 is held at the two bending grooves 4 on the outer surface, the rubber anti-slip strips 5 can increase the friction between the fingers and the inner wall of the bending groove 4, making it less likely for the operator to slip when holding the handle 1.
[0031] Reference Figure 1-4 As shown in this embodiment: the grouting component 3 includes a rotating shaft 31 and a scraper 32. The scraper 32 is mounted on the end of the handle 1 away from the grouting head 2 via the rotating shaft 31. A torsion spring 33 is provided on the outer surface of the rotating shaft 31. The torsion spring 33 is installed on the outside of the rotating shaft 31 to limit the rotation angle of the rotating shaft 31. A protruding rod 34 is fixedly connected to one side of the top of the scraper 32. When using the grouting device, when it is necessary to scrape off excess mortar on the wall, the finger holding the surface of the handle 1 near the grouting component 3 can be used to push the protruding rod 34 to control the scraper 32 to rotate inwards from the rotating shaft 31 towards the handle 1, so that the angle between the scraper 32 and the handle 1 tends to be perpendicular. Straighten the scraper 32, then place one end of the scraper 32 against the wall, and pull the handle 1 horizontally to scrape off excess mortar from the wall using the scraper 32, further improving the practicality of the grouting device. Releasing the protruding rod 34 will cause the torsion spring 33 to return to its original state, which will drive the rotating shaft 31 and the scraper 32 to rotate back to their original angle. An auxiliary groove 35 is provided on one side of the scraper 32. The internal shape of the auxiliary groove 35 is arc-shaped. By setting the arc-shaped auxiliary groove 35, when the scraper 32 moves to scrape off mortar on one side of the wall, the mortar is more likely to enter the arc-shaped auxiliary groove 35 on the surface of the scraper 32, and is less likely to enter between the scraper 32 and the wall, thus improving the performance of the scraper 32.
[0032] Working principle: When using the grouting device to grout the mortar joints, hold the handle 1 with your thumb and other fingers on the two curved grooves 4 on the outer surface of the handle 1. When you need to grout a flat joint, place the beveled side of the flat head 21 against the joint and control the movement of the handle 1 and the flat head 21. The beveled side of the flat head 21 will smooth the mortar joint, and the mortar overflowing into the joint will enter the surface of the guide plate 23. The guide plate 23 will guide the overflowing mortar away from the flat head 21, or the flat head 21 will pick up some mortar and bring it into the joint. Move the flat head 21 to grout. When you need to grout a groove, hold the handle 1 to further control the tilt of the grouting head 2. Then, place one side of the curved head 22 against the mortar joint, and move the curved head 22 to perform grouting treatment on the mortar joint. When it is necessary to scrape off excess mortar on the wall, you can use your fingers holding the surface of the handle 1 near the scraping component 3 to push the protruding rod 34 to control the scraper 32 to rotate inwards through the pivot 31, so that the angle between the scraper 32 and the handle 1 tends to be perpendicular. Then, place one end of the scraper 32 against the wall, hold the handle 1 flat and pull the handle 1 horizontally to scrape off excess mortar on the wall through the scraper 32. Release the protruding rod 34, and the torsion spring 33 will return to its original state, which will drive the pivot 31 and the scraper 32 to rotate back to the original angle.
