[0024] Please see Figure 1-7This invention provides a technical solution: a simple masonry mortar joint control device, comprising an angle steel 1 and a square tube 2, wherein the angle steel 1 and the square tube 2 are arranged symmetrically, with the square tube 2 located below the angle steel 1, and the angle steel 1 and the square tube 2 are assembled into a rectangular shape; the square tube 2 is slidably installed with the angle steel 1; each square tube 2 is provided with a limiting mechanism for fixing the square tube 2; each square tube 2 is slidably connected to a measuring plate 3 in the vertical direction, and a first screw 4 is fixedly connected to the measuring plate 3, with a first locking nut 5 threadedly connected to the first screw 4; a scraper 6 is provided above the square tube 2, and the bottom of the scraper 6 is provided with serrations.

[0025] In practice, before construction, the construction technicians understand and grasp the width of the masonry and the mortar joints according to the construction drawings; then, they adjust the height of the measuring plate 3 according to the mortar joint thickness; it should be noted that a mortar joint thickness scale line can be set on the side wall of the square tube 2 near the first locking nut 5; the height between the bottom surface of the measuring plate 3 and the top surface of the square tube 2 is the mortar joint thickness; after the construction personnel loosen the first locking nut 5, they push the measuring plate up and down, and after the measuring plate 3 moves to the designated position, they tighten the first locking nut 5. At this time, the first locking nut 5 will cooperate with the first screw 4 to firmly fix the measuring plate 3; then the construction personnel will use the device of the present invention... Figure 4 The device is placed on the block as shown in the diagram. The workers then move the two square tubes 2 horizontally inwards or outwards until they are flush with the front and rear walls of the block. The limiting mechanism then fixes the square tubes 2, keeping them flush with the block. The distance between the inner walls of the two square tubes 2 is the width of the block. The workers then fill the groove formed by the device and the masonry with the mixed mortar, ensuring the mortar is fully applied. A serrated scraper 6 is used to scrape the mortar from one end of the device to the other, perpendicular to the wall. The device is then horizontally pulled and moved to the next block. Note that it is not necessary to lift the device and place it on another block; simply move it horizontally. Once the surface of a layer of blocks at the same height is reached… After laying the mortar, the required blocks are laid on top of the mortar, and then hammered evenly several times with a rubber mallet to ensure full contact between the blocks and the mortar. This invention, through the setting of the measuring plate 3, the first screw 4, and the first locking nut 5, allows for the adjustment of the height of the measuring plate 3 to accommodate mortar joints of different thicknesses. After one mortar pour is completed, the device can be directly pulled horizontally to the next block without needing to be lifted, thus avoiding shaking of the measuring plate 3 due to operator error and ensuring consistent mortar joint thickness. The device of this invention has a simple structure, is easy to process and assemble, is simple to operate during construction, and has significant effects. Construction is safe and reliable, and it can effectively control the quality of masonry.

[0026] Example 1: The limiting mechanism includes a second screw 7. There are two second screws 7. The two second screws 7 are fixedly installed at the top two ends of the square tube 2. The two second screws 7 are slidably installed with the two angle steels 1. Each of the second screws 7 is threadedly connected with a second locking nut 8. The second locking nut 8 is located above the angle steel 1.

[0027] In specific work, such as Figure 2 As shown, when it is necessary to adjust the distance between the two square tubes 2 so that the square tubes 2 fit against the block, the worker loosens the second locking nut 8; then the worker can move the two square tubes 2 horizontally until both square tubes 2 fit against the front and rear side walls of the block respectively. Then the worker tightens the second locking nut 8 downwards until the second locking nut 8 fits tightly against the angle steel 1. At this time, the second locking nut 8, together with the second screw 7, fixes the square tubes 2. In this embodiment, after the square tubes 2 are moved to fit against the block, the square tubes 2 can be fixed by tightening the second locking nut 8, which has the advantages of low cost and simple operation.

[0028] Example 2: The limiting mechanism includes a bidirectional threaded rod 9 and a sliding rod 10. The bidirectional threaded rod 9 is rotatably connected to the left angle steel 1, and the sliding rod 10 is fixedly connected to the right angle steel 1. The left ends of the two square tubes 2 are respectively threaded to the two ends of the bidirectional threaded rod 9, and the right ends of the two square tubes 2 are slidably connected to the sliding rod 10.

[0029] In specific work, such as Figure 1 As described above, Figure 2 As shown, when it is necessary to adjust the distance between the two square tubes 2 so that the square tubes 2 fit against the block, the construction worker drives the bidirectional threaded rod 9 to rotate by operating an external motor (not shown in the figure). The bidirectional threaded rod 9 can drive the two square tubes 2 to slide on the slide rod 10. The two square tubes 2 will move towards each other until they fit against the block. Then the external motor stops working, and the two square tubes 2 remain in the state of fitting against the block. In this embodiment, through the setting of the bidirectional threaded rod 9 and the slide rod 10, the external motor can drive the bidirectional threaded rod 9 to move the two square tubes 2 synchronously towards the side closer to the block, without the need for the construction worker to manually adjust the position of the square tubes 2, which can greatly save construction time.

[0030] As a further embodiment of the present invention, a driving mechanism is provided at the bottom of each square tube 2. The driving mechanism is used to drive the square tube 2 to move on the block. The driving mechanism includes a mounting base 11, which is fixedly installed at the bottom of the square tube 2. Both the left and right ends of the mounting base 11 are rotatably connected to sprockets 12. A tension wheel 13 is also rotatably connected to the middle of the mounting base 11. The tension wheel 13 and the two sprockets 12 are connected to a chain 14 for transmission. Several fixed rods 15 are fixedly connected at equal intervals at the bottom end of the chain 14. A suction cup 16 is fixedly connected to the end of each fixed rod 15 away from the chain 14.

[0031] In specific work, such as Figure 1-5 As shown, when the square tube 2 moves to fit against the block, the suction cup 16 near the block also moves synchronously to fit against the block; it should be noted that, as Figure 3 As shown, in the initial state, the inner suction cup 16 is located inside the square tube 2; that is, when the square tube 2 moves to fit against the block, the suction cup 16 adheres to the vertical sidewall of the block. Figure 4 As shown, after the mortar on the top of a block is laid, the construction worker starts an external motor (not shown) to drive one of the sprockets 12 to rotate. The sprocket 12 drives the chain 14, which in turn drives the fixing rod 15 and the suction cup 16 to move synchronously. Figure 3 As shown, when the sprocket 12 rotates counterclockwise, the suction cup 16 will drive the entire device to move to the right relative to the block. When the outer suction cup 16 moves from the rightmost side of the chain 14 to the inner side, it will adhere to the block. At the same time, when the inner suction cup 16 moves from the leftmost side of the chain 14 to the outer side, it will detach from the block. Through the cyclic adsorption of multiple suction cups 16, the entire device can move smoothly horizontally without the need for workers to manually push the entire device. The right end of the chain 14 can be moved to the outside of the block, ensuring that the mortar can be completely laid to all areas on top of the block. At the same time, the connection between the mounting base 11 and the square tube 2 can be set to be detachable, allowing construction workers to choose whether to use the drive mechanism based on their physical strength. This can greatly improve the efficiency of mortar joint laying.

[0032] As a further embodiment of the present invention, the fixing rod 15 is a telescopic rod, and a return spring is provided inside the fixing rod 15.

[0033] In actual operation, the fixing rod 15 is set as a telescopic rod, and a return spring is set inside the fixing rod, so that the suction cup 16 can be better attached to the side wall of the block.

[0034] As a further embodiment of the present invention, each square tube 2 is provided with two measuring plates 3, and the two measuring plates 3 are respectively provided on the left and right sides of the square tube 2; the measuring plate 3 is composed of a base 17 and a plate body 18, the base 17 is slidably connected to the square tube 2 in the vertical direction, the plate body 18 is rotatably installed on the top of the base 17, and a locking block 19 is inserted into the plate body 18, and the locking block 19 is slidably installed with the base 17.

[0035] In specific work, such as Figure 6As shown, in the initial state, the locking block 19 is inserted into the plate 18, and the plate 18 cannot rotate. After the construction personnel adjust the height of the plate 18, the entire device can be placed on the block. At this time, the bottom surface of the plate 18 is in contact with the block, and the entire device is temporarily supported by the plate 18. After the two square tubes 2 move to be in contact with the block, the suction cup 16 is attached to the surface of the block, which can provide support for the entire device. Then the construction personnel can pull the locking block 19 out of the plate 18 and then rotate the plate 18 upward. At this time, the square tubes 2 maintain the specified height. It should be noted that setting the measuring plate on the left and right sides of the square tubes 2 can prevent the measuring plate from directly contacting the mortar, and the mortar will not submerge the plate 18. At the same time, rotating the plate 18 upward can ensure that the plate 18 will not disturb the laid mortar when the device is moved, so that the thickness of the mortar joint can be better kept consistent.

[0036] As a further embodiment of the present invention, each of the sprockets 12 has a first bevel gear 20 fixedly connected to its rotating shaft. Each first bevel gear 20 meshes with a second bevel gear 21. The second bevel gears 21 are incomplete gears. Each second bevel gear 21 is rotatably connected to the square tube 2. Each rotating shaft of the second bevel gear 21 is equipped with a one-way bearing 22, and the two one-way bearings 22 rotate in opposite directions. Each one-way bearing 22 has a take-up roller 23 fixedly connected to its outer circumferential wall, and each take-up roller 23 has a first traction rope 24 wound around it. One end of 24 is fixedly connected to the take-up roller 23, and the other end is fixedly connected to a slide plate 25; the slide plate 25 is slidably connected to the left and right side walls of the square tube 2 respectively; the slide plate 25 is slidably connected to a pull rod 26 in the vertical direction, the pull rod 26 is slidably connected to the base 17 in the horizontal direction, a second traction rope 27 is fixedly connected to the pull rod 26, and the end of the second traction rope 27 away from the pull rod 26 passes through the base 17 and is fixedly connected to the top of the plate body 18; the slide plate 25 is slidably connected to a slider 28 in the vertical direction, and the slider 28 is fixedly connected to the locking block 19.

[0037] In specific work, such as Figures 5-7As shown, when the sprocket 12 rotates, it drives the first bevel gear 20 to rotate, which in turn drives the second bevel gear 21 to rotate. The second bevel gear 21 then drives the take-up roller 23 to rotate via the one-way bearing 22. It should be noted that the two one-way bearings 22 on the left and right sides have opposite rotational directions. When the entire device moves to the right, the one-way bearing 22 on the left drives the take-up roller 23 on the left to rotate, while the one-way bearing 22 on the right does not drive the take-up roller 23 on the right. The rotation of the take-up roller 23 will wind up the first traction rope 24, which will then drive the slide plate 25 to move outward. The slide plate 25 will first drive the locking block 19 to move outward via the slider 28 and the plate body. 18 detaches, and then the slide plate 25 will drive the plate 18 to rotate upward through the pull rod 26 and the second traction rope 27. At this time, the left plate 18 rotates to a position where it does not contact the block, and because the suction cup 16 is attached to the block, the plate 18 will always remain raised unless the sprocket 12 rotates counterclockwise. This ensures that the left plate 18 will not disturb the laid mortar when it moves to the right. When the device moves to the right, the right plate can remain in contact with the block, which can better ensure that the mortar joint thickness is consistent. Conversely, if the device moves to the left, the right plate 18 will be raised, while the left plate 18 can always remain in contact with the block.

[0038] As a further embodiment of the present invention, each of the two square tubes 2 is slidably connected to a slide block 29; both slide blocks 29 are slidably mounted on the bottom of the scraper 6; a second threaded rod 30 is rotatably mounted on the front side wall of the front square tube 2, and the front slide block 29 is threadedly connected to the second threaded rod 30.

[0039] In specific work, such as Figure 1 As shown, the second threaded rod 30 can be driven to rotate by an external motor. The second threaded rod can drive the slide 29 to move in the left and right directions. The slide 29 will drive the scraper 6 to move synchronously. The scraper 6 can automatically scrape the laid mortar into a sawtooth shape.

[0040] Working principle: Before construction, construction technicians understand and grasp the width of the masonry and the mortar joints according to the construction drawings; then, they adjust the height of the measuring plate 3 according to the mortar joint thickness; it should be noted that a mortar joint thickness scale line can be set on the side wall of the square tube 2 near the first locking nut 5; the height between the bottom surface of the measuring plate 3 and the top surface of the square tube 2 is the mortar joint thickness; after the construction personnel loosen the first locking nut 5, they push the measuring plate up and down. After the measuring plate 3 moves to the designated position, they tighten the first locking nut 5. At this time, the first locking nut 5 will cooperate with the first screw 4 to firmly fix the measuring plate 3; then the construction personnel will use the device of the present invention... Figure 4The device is placed on the block as shown in the diagram. The workers then move the two square tubes 2 horizontally inwards or outwards until they are flush with the front and rear walls of the block. The limiting mechanism then fixes the square tubes 2, keeping them flush with the block. The distance between the inner walls of the two square tubes 2 is the width of the block. The workers then fill the groove formed by the device and the masonry with the mixed mortar, ensuring the mortar is fully applied. A serrated scraper 6 is used to scrape the mortar from one end of the device to the other, perpendicular to the wall. The device is then horizontally pulled and moved to the next block. Note that it is not necessary to lift the device and place it on another block; simply move it horizontally. Once the surface of a layer of blocks at the same height is reached… After laying the mortar, the required blocks are laid on top of the mortar, and then hammered evenly several times with a rubber mallet to ensure full contact between the blocks and the mortar. This invention, through the setting of the measuring plate 3, the first screw 4, and the first locking nut 5, allows for the adjustment of the height of the measuring plate 3 to accommodate mortar joints of different thicknesses. After one mortar pour is completed, the device can be directly pulled horizontally to the next block without needing to be lifted, thus avoiding shaking of the measuring plate 3 due to operator error and ensuring consistent mortar joint thickness. The device of this invention has a simple structure, is easy to process and assemble, is simple to operate during construction, and has significant effects. Construction is safe and reliable, and it can effectively control the quality of masonry.
