Technical Field
[0001] This utility model relates to the field of wall masonry tools, and in particular to a tool for improving the quality of mortar joints in masonry construction. Background Technology
[0002] Mortar joints mostly refer to the mortar layer between two bricks during wall construction. They are the joint lines formed after bricks are bonded together with mortar. Mortar joints are divided into horizontal and vertical joints. The joint between the upper and lower layers of bricks is called a horizontal joint, while the joint between adjacent bricks is called a vertical joint. Mortar joints affect the strength, insulation, heat insulation, impermeability, and frost resistance of the masonry. In brick masonry, the thickness of mortar joints is generally 10mm, but should not be less than 8mm or greater than 12mm. In recent years, with the national two-year quality action campaign, the construction industry has faced severe challenges and increasingly fierce competition. Improving the construction quality of masonry projects and reducing project costs is imperative. However, the construction of mortar joints in existing secondary structure masonry has a high degree of arbitrariness, and its quality mainly depends on the worker's skill. Uneven mortar joint thickness and mortar fullness failing to meet specifications are common problems. Therefore, this paper proposes a tool to improve the quality of mortar joints in masonry construction to address these issues. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tool to improve the quality of mortar joints in masonry construction, effectively solving the deficiencies of the prior art.
[0004] To achieve the above objectives, one embodiment of this utility model provides a tool for improving the quality of mortar joints in masonry construction. The tool includes an installation frame mounted on the top of a wall and movable along the wall. One end of the installation frame curves upward to form a raised frame. A horizontally placed horizontal strip is installed in the middle of the top wall of the raised frame. Two guide grooves are provided on both sides of the installation frame near the raised frame, and two fastening bolts are installed inside each of the four grooves. A guide plate for limiting the placement of bricks is installed at one end of two adjacent fastening bolts. A cement forming frame is installed inside the installation frame away from the raised frame. The cement forming frame has an opening at one end near the guide plate. A hand handle is installed on the top surface of the cement forming frame, and a scraper for applying mortar is installed on the bottom surface of the hand handle.
[0005] Preferably, in any of the above schemes, the mounting frame is equipped with first limiting wheels at the two corners away from the protrusion, and the top of each of the two side walls of the protrusion is equipped with second limiting wheels. Both of these wheels and the first limiting wheels are stepped in shape. This scheme facilitates the placement of the mounting frame and the two second limiting wheels are installed at a relatively high height, which makes it easy to arrange them according to the shape of the wall and to move along its top surface. By moving the mounting frame, the top of the wall can be built layer by layer.
[0006] Preferably, in any of the above schemes, the tops of the four guide plates are all tilted upwards away from the wall, and the distance between the two guide plates on the same side that are far apart is less than the length of the cement molding frame. By using this scheme, it is easy for excess cement mortar to accumulate on the inner wall of the cement molding frame. At the same time, the opening of the cement molding frame faces the placement direction of the brick, which is convenient for applying cement mortar to the bonding position of the brick using a scraper.
[0007] Preferably, the top of the cement forming frame is trumpet-shaped, and the width of its bottom end is smaller than the width of the external wall. This design allows the top of the cement forming frame to be open, making it easier for operators to use scooping tools to apply cement mortar inside the frame. Because the bottom of the cement forming frame is narrow, a certain gap is left between the edge of the applied cement mortar and the sides of the wall. As the bricks are laid and pressed and hammered later, the cement mortar is squeezed outward, filling the gaps and completing the placement of the bricks, while limiting the amount of cement mortar overflowing.
[0008] Preferably, the four corners of the cement molding frame are fixedly connected to the two sides of the mounting frame by bolts, and a horizontal handle is installed on one side of the cement molding frame. This design provides a gripping position for the operator, making it easier for the operator to push the whole frame through the horizontal handle.
[0009] Preferably, in any of the above embodiments, the scraper's shape is adapted to the inner wall shape of the cement forming frame, and the bottom end of the scraper is serrated. This design facilitates stable contact between the scraper's side and the inner wall of the cement forming frame, thereby pushing the scraper to facilitate the application of cement mortar. Simultaneously, the serrated structure at the bottom of the scraper helps to create a wavy surface on the cement mortar, allowing air to escape along the grooves after the brick is pressed in.
[0010] This utility model has the following advantages: 1. This tool for improving the quality of mortar joints in masonry construction, by setting up an installation frame, a raised frame, two first limiting wheels, and a second limiting wheel, facilitates direct installation of the tool at the masonry position on the top surface of the wall. Cement is piled inside the cement forming frame, and then the operator uses the handle to drive the scraper to spread the mortar at the brick placement position. Subsequently, the operator holds the horizontal handle and moves the entire tool, causing the four guide plates to move to the brick placement position. The operator places the brick between the four guide plates and presses it down, ensuring that its top surface is consistent with the top surface of the bricks in the same layer, thereby ensuring the fullness and uniformity of the overall mortar, thus effectively solving the problems existing in the prior art.
[0011] 2. This tool for improving the quality of mortar joints in masonry construction is equipped with an installation frame, a raised frame, a first limiting wheel, and two second limiting wheels. Both the first and second limiting wheels are stepped, which facilitates limiting the placement of the tool. By setting a horizontal bar, as the tool is pushed forward, it is used to observe whether the two second limiting wheels detach from the brick, measure the placement height of the brick, and ensure the flatness of the wall construction.

[0014] 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.
[0015] like Figures 1 to 6 As shown, a tool for improving the quality of mortar joints in masonry construction includes an installation frame 1 installed at the top of a wall and movable along the wall. One end of the installation frame 1 is raised upward to form a protruding frame 12. A horizontally placed horizontal strip 5 is installed in the middle of the top wall of the protruding frame 12. Two guide grooves 3 are opened on both sides of the installation frame 1 near the protruding frame 12, and two fastening bolts 2 are installed inside each of the four grooves. A guide plate 4 for limiting the placement of bricks is installed at one end of two adjacent fastening bolts 2. A cement forming frame 9 is installed inside the installation frame 1 away from the protruding frame 12. The cement forming frame 9 is open at one end near the guide plate 4. A hand handle 7 is installed on the top surface of the cement forming frame 9, and a scraper 8 for applying mortar is installed on the bottom surface of the hand handle 7.
[0016] The mounting frame 1 is equipped with first limiting wheels 10 at the two corners away from the protrusion frame 12. The top of each side wall of the protrusion frame 12 is equipped with second limiting wheels 6. Both of these wheels and the first limiting wheels 10 are stepped in shape. As an optional technical solution of this utility model, this makes it easier to limit the placement of the mounting frame 1. At the same time, the two second limiting wheels 6 are installed at a relatively high height, which makes it easy to arrange them according to the shape of the wall and to move along its top surface. By moving the mounting frame 1, the top of the wall can be built layer by layer.
[0017] The tops of the four guide plates 4 are all tilted upwards away from the wall. The distance between the two guide plates 4 on the same side is less than the length of the cement forming frame 9. As an optional technical solution of this utility model, this makes it easier for excess cement mortar to accumulate on the inner wall of the cement forming frame 9. At the same time, the opening of the cement forming frame 9 faces the placement direction of the brick, which makes it easy to use the scraper 8 to apply cement mortar to the bonding position of the brick.
[0018] The top of the cement forming frame 9 is trumpet-shaped, and the width of its bottom end is smaller than the width of the external wall. As an optional technical solution of this utility model, this makes it easier for the top of the cement forming frame 9 to have an open design, which makes it easier for the operator to use a scooping tool to apply cement mortar to the inside of the cement forming frame 9. Since the bottom end of the cement forming frame 9 is narrow, it is easy to leave a certain gap between the edge of the applied cement mortar and the two sides of the wall. With the construction of the bricks and the subsequent pressing and knocking, the cement mortar is squeezed outward, and the cement mortar extends outward to fill the gap, completing the placement of the bricks, while limiting the amount of cement mortar overflowing.
[0019] The four corners of the cement molding frame 9 are fixedly connected to the two sides of the mounting frame 1 by bolts. A horizontal handle 11 is installed on one side of the cement molding frame 9. As an optional technical solution of this utility model, this provides a gripping position for the operator, and makes it easier for the operator to push the whole through the horizontal handle 11.
[0020] The scraper 8 is shaped to fit the inner wall of the cement forming frame 9. The bottom end of the scraper 8 is serrated, which, as an optional technical solution of this invention, facilitates a stable fit between the side of the scraper 8 and the inner wall of the cement forming frame 9, thereby promoting the application of cement mortar. Simultaneously, the serrated structure at the bottom of the scraper 8 helps to create a wavy surface on the cement mortar, allowing air to escape along the grooves after the brick is pressed.
[0021] This tool for improving the quality of mortar joints in masonry construction requires the following steps when used: 1) When using, place the tool at the top of the wall, and simultaneously lock the first limiting wheel 10 and the second limiting wheel 6 at the corner of the brick. 2) Place the cement inside the cement molding frame 9, and at the same time, hold the hand handle 7 and move it diagonally upward and horizontally to spread the mortar evenly. 3) Hold the horizontal handle 11 and move the whole thing so that the four guide plates 4 move to the placement position of the brick; 4) The operator places the brick between the four guide plates 4 and presses it down or uses a tool to tap it to complete the placement of the brick.
[0022] In summary, when using the tool, the installation frame 1, the raised frame 12, the two first limiting wheels 10, and the second limiting wheel 6 facilitate direct installation at the bricklaying position on the top surface of the wall. Cement is placed inside the cement forming frame 9. Then, the user operates the handle 7 to drive the scraper 8 to apply the cement to the brick placement position. Subsequently, the user holds the horizontal handle 11 to move the entire tool, causing the four guide plates 4 to move to the brick placement position. The operator places the brick between the four guide plates 4 and presses it down so that its top surface aligns with the top surface of the bricks in the same layer. To maintain consistency and ensure the fullness and uniformity of the overall mortar, thus effectively solving the problems existing in the prior art, the tool is installed with a frame 1, a raised frame 12, a first limiting wheel 10, and two second limiting wheels 6. The first limiting wheel 10 and the second limiting wheel 6 are both stepped, which facilitates limiting the placement of the tool. By setting a horizontal bar 5, as the tool is pushed forward, it is used to observe whether the two second limiting wheels 6 detach from the brick and to measure the placement height of the brick, ensuring the flatness of the wall construction.
[0023] 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.
