Description

Technical Field

[0001] This utility model relates to the field of masonry construction technology, and in particular to a tool that can improve the quality of mortar joints in masonry construction. Background Technology

[0002] The mortar joint (also known as "masonry mortar joint") is the mortar filling layer between bricks, stones or blocks when building a wall. It is used to bond the blocks, transfer loads, adjust the flatness of the masonry, and improve the integrity and durability of the wall. In brick masonry, the thickness of the mortar joint is generally 10mm, but should not be less than 8mm or more than 12mm.

[0003] When constructing masonry walls, the construction of mortar joints in the wall structure is highly arbitrary, and the construction quality depends on the experience and skills of the workers. When the workers' technical experience is low, uneven mortar joint thickness and mortar fullness often occur in the walls. Based on this, a tool that can improve the quality of mortar joints in masonry construction is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tool that can improve the quality of mortar joints in masonry construction, effectively solving the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides a tool that can improve the quality of mortar joints in masonry construction, including a support frame straddling a wall. Two horizontally placed guide rails are installed on both sides of the middle part of the support frame. A mortar hopper that can move linearly along its length is installed between the two guide rails. A push plate that can slide vertically is provided at the top of the mortar hopper, and an operating handle is installed in the middle of its top surface.

[0006] A limiting frame is installed on one side of the ash hopper, and a scraper is installed between the limiting frame and the side of the ash hopper. A vertically placed first stud is installed in the middle of the top surface of the limiting frame, and its top end penetrates the top end of the scraper. Two adjusting nuts are threaded onto the top end of the first stud.

[0007] Preferably, in any of the above embodiments, two vertically placed fixing plates are installed on both sides of the bottom end of the support frame, and the bottom ends of the four fixing plates are threaded with second studs. Pressure plates are rotatably installed between the adjacent ends of the four second studs, and handwheels are fixedly connected to the far ends of the four second studs. This embodiment facilitates the clamping of the fixing plates against the external wall by rotating the four handwheels, locking the position of the support frame, and making it convenient for the operator to push the ash hopper to move in a straight line.

[0008] Preferably, in any of the above solutions, multiple connecting plates are installed on the sides of the two guide rails that are far apart. The bottom ends of the multiple connecting plates are fixedly connected to both sides of the support frame by bolts. A gap is left between the adjacent sides of the two guide rails and the external wall. By using this solution, it is easy to stably install the two guide rails on both sides of the support frame, while leaving a certain distance between them and the sides of the wall to avoid interfering with the horizontal movement of the ash hopper. Since the connecting plates are fixedly connected to the support frame by bolts, it is convenient to replace the worn guide rails later.

[0009] Preferably, in any of the above-mentioned schemes, support wheels are installed at both corners of the ash hopper, and the four support wheels are respectively rolledly connected to two guide rails. This scheme facilitates stable support of the ash hopper and facilitates rolling connection with the two guide rails, thereby facilitating the horizontal movement of the ash hopper along the length of the guide rails. The rolling connection between the support wheels and the guide rails effectively prevents the ash hopper from tipping over and leaves a certain gap between the bottom of the ash hopper and the top surface of the wall, avoiding interference with the horizontal movement of the ash hopper.

[0010] Preferably, in any of the above schemes, a through groove is provided at the bottom end of the ash hopper near the scraper plate, and a gap is left between the bottom end of the ash hopper and the top surface of the external wall. In this scheme, the through groove facilitates the mortar to flow out from it to the outside, while the bottom end of the ash hopper does not contact the wall, thus avoiding interference with the horizontal movement of the ash hopper.

[0011] Preferably, the bottom of the scraper plate is serrated, and the top of the scraper plate protrudes outward to form a raised part, which is located between two adjusting nuts. This design facilitates the scraper plate to smooth the mortar and forms several grooves on the top surface of the mortar, thereby achieving the grooving treatment of the mortar. When the brick is placed in the mortar, the grooves facilitate the air to escape, thereby reducing the risk of hollowing and making the adhesion stronger.

[0012] This utility model has the following advantages:

[0013] 1. This tool can improve the quality of mortar joints in masonry construction. It features a support frame with guide rails on both sides. A mortar hopper moves along the length of the guide rails via four support wheels. A scraper is installed on one side of the hopper. The support frame straddles the external wall, and mortar is poured into the hopper. A pusher plate presses down on the mortar, simultaneously pushing the hopper along the guide rails. This facilitates the even application of mortar to the top surface of the bricks, ensuring consistent mortar thickness. This allows for control over the mortar coating thickness, facilitating subsequent bricklaying and effectively solving the problems existing in current technologies.

[0014] 2. This tool can improve the quality of mortar joints in masonry construction. It has four fixing plates, and each of the four plates has a second stud threaded onto its bottom end. At the same time, pressure plates and handwheels are installed at both ends of the second studs. After the support frame is placed, the four handwheels are rotated to push the fixing plates to clamp the external wall and lock the position of the support frame, so that the operator can push the mortar hopper to move in a straight line.

[0015] 3. This tool can improve the quality of mortar joints in masonry construction. It is equipped with a limiting frame, a scraper, a first stud, and two adjusting nuts. By rotating the adjusting nuts, the installation height of the scraper can be adjusted, and the coating thickness of the mortar can be adjusted to meet the masonry requirements of the wall.

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 5As shown, a tool that can improve the quality of mortar joints in masonry construction includes a support frame 1 straddling the wall. The support frame 1 is also made of aluminum alloy profile and is connected by welding to form a stable structure. It is also lightweight, making it easy for operators to move the support frame 1. Two horizontally placed guide rails 8 are installed on both sides of the middle part of the support frame 1. A mortar hopper 7 that can move linearly along its length is installed between the two guide rails 8. A vertically sliding push plate 5 is provided at the top of the mortar hopper 7, and an operating handle 6 is installed in the middle of its top surface.

[0024] A limiting frame 15 is installed on one side of the ash hopper 7. A scraper plate 9 is installed between the limiting frame 15 and the side of the ash hopper 7. A vertically placed first stud 14 is installed in the middle of the top surface of the limiting frame 15, and its top end penetrates the top end of the scraper plate 9. Two adjusting nuts 13 are threaded on the top end of the first stud 14.

[0025] Two vertically placed fixing plates 4 are installed on both sides of the bottom end of the support frame 1. The bottom ends of the four fixing plates 4 are threaded with second studs 10. Pressure plates 2 are rotatably installed between the adjacent ends of the four second studs 10. Handwheels 3 are fixedly connected to the far ends of the four second studs 10. As an optional technical solution of this utility model, this makes it easy to push the fixing plates 4 to clamp the external wall by rotating the four handwheels 3, lock the position of the support frame 1, and make it easy for the operator to push the ash hopper 7 to move in a straight line.

[0026] Multiple connecting plates are installed on the sides of the two guide rails 8 that are far apart. The bottom ends of the multiple connecting plates are fixedly connected to both sides of the support frame 1 by bolts. A gap is left between the adjacent sides of the two guide rails 8 and the external wall. As an optional technical solution of this utility model, this makes it easy to stably install the two guide rails 8 on both sides of the support frame 1, while leaving a certain distance between them and the sides of the wall to avoid interfering with the horizontal movement of the ash hopper 7. Since the connecting plates are fixedly connected to the support frame 1 by bolts, it is convenient to replace the worn guide rails 8 later.

[0027] Support wheels 11 are installed at both corners of the ash hopper 7. The four support wheels 11 are respectively rolledly connected to two guide rails 8. As an optional technical solution of this utility model, this facilitates stable support for the ash hopper 7 and facilitates rolling connection with the two guide rails 8, thereby facilitating the horizontal movement of the ash hopper 7 along the length of the guide rails 8. The rolling connection between the support wheels 11 and the guide rails 8 can effectively prevent the ash hopper 7 from tipping over and leave a certain gap between the bottom of the ash hopper 7 and the top surface of the wall to avoid interference with the horizontal movement of the ash hopper 7.

[0028] A through groove 16 is provided at the bottom end of the ash hopper 7 near the scraper plate 9. A gap is left between the bottom end of the ash hopper 7 and the top surface of the external wall. As an optional technical solution of this utility model, the through groove 16 facilitates the mortar to flow out from it to the outside. At the same time, the bottom end of the ash hopper 7 does not contact the wall, so as to avoid interfering with the horizontal movement of the ash hopper 7.

[0029] The bottom of the scraper plate 9 has a serrated shape, and the middle of the top of the scraper plate 9 protrudes outward to form a raised part, which is located between the two adjusting nuts 13. As an optional technical solution of this utility model, this makes it easier for the scraper plate 9 to smooth the mortar, and at the same time, it forms several grooves on the top surface of the mortar, thereby realizing the groove treatment of the mortar. When the brick is placed in the mortar, the grooves facilitate the air to be discharged, thereby reducing the risk of hollowing and making the adhesion stronger.

[0030] This tool can improve the quality of mortar joints in masonry construction. The following steps are required when using it:

[0031] 1) When using, place the support frame 1 on the external wall and use a level to adjust the levelness of the support frame 1;

[0032] 2) Rotate the handwheel 3 to push the pressure plate 2 to move relative to each other, press the external wall, and make the support frame 1 stably installed on the external wall;

[0033] 3) Pour the mortar into the ash hopper 7, and at the same time place the push plate 5 inside the ash hopper 7;

[0034] 4) The operator holds the operating handle 6 with one hand and presses the mortar down through the push plate 5;

[0035] 5) With the other hand, the operator pushes the ash hopper 7 to slide along the length of the guide rail 8 to complete the uniform coating of mortar.

[0036] In summary, when the user operates the system, a support frame 1 is installed with guide rails 8 on both sides. The mortar hopper 7 moves along the length of the guide rails 8 via four support wheels 11. Simultaneously, a scraper 9 is installed on one side of the mortar hopper 7. The support frame 1 straddles the external wall, and mortar is poured into the mortar hopper 7. A pusher plate 5 presses down on the mortar, simultaneously pushing the mortar hopper 7 along the length of the guide rails 8. This facilitates the even application of mortar to the top surface of the bricks, ensuring a consistent mortar thickness. This allows for control over the mortar application thickness, facilitating subsequent bricklaying and effectively solving the problems existing in current technologies. To address this issue, four fixing plates 4 are installed, each with a second stud 10 threaded onto its bottom. Each second stud 10 has a pressure plate 2 and a handwheel 3 installed at both ends. After placing the support frame 1, the four handwheels 3 are rotated to clamp the fixing plates 4 onto the external wall, locking the position of the support frame 1. This allows the operator to push the mortar hopper 7 in a straight line. Finally, by setting a limit frame 15, a scraper 9, a first stud 14, and two adjusting nuts 13, the installation height of the scraper 9 can be adjusted by rotating the adjusting nuts 13, thus adjusting the mortar coating thickness to meet the wall construction requirements.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
