Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a masonry grouting tool. Background Technology

[0002] In the construction of masonry structures in building engineering, it is often necessary to perform grouting on the wall surface. Grouting refers to filling the gaps between two adjacent masonry blocks with mortar. Its function is to effectively make the connection between the masonry blocks on the top, bottom, left and right sides stronger, prevent wind and rain from penetrating the interior of the wall, and make the wall surface clean, neat and beautiful.

[0003] Traditional grouting construction typically involves the following steps: First, use a scraper or trowel to remove excess mortar protruding from the brick joints for pretreatment. Then, use tools such as steel hooks and rubber rods to press grout into the brick joints to form concave grooves. Finally, use tools such as brushes and damp cloths to clean the residual mortar on the brick surface around the joints.

[0004] However, existing grouting methods have the following problems: Firstly, the construction process requires repeated tool changes and frequent manual actions, resulting in low operational efficiency and discontinuous construction rhythm, which cannot meet the needs of large-area, high-standard fair-faced wall construction. Secondly, the grouting process is highly dependent on the experience and strength control of the construction personnel, which can easily lead to problems such as inconsistent pressing depth and inconsistent seam shape, affecting the appearance of the finished product.

[0005] Third, the separation of cleaning and grouting operations often results in residual mortar after grouting has already begun to set, making cleaning difficult and easily contaminating the brick surface, thus increasing the cost of later repairs and cleaning.

[0006] Therefore, it is necessary to study a masonry grouting tool. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a masonry grouting tool that can effectively solve the problems of needing to repeatedly change tools, inconsistent pressing depth, and separation of cleaning and grouting operations.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A masonry grouting tool includes a connecting rod, axle, roller, grouting ring, shovel hopper, and cleaning brush; One end of the connecting rod is fixedly connected to an axle, and rollers are rotatably mounted on both ends of the axle; the other end of the connecting rod is fixedly connected to a handle. The grouting ring is detachably connected to the connecting rod and coaxially surrounds the middle of the wheel axle; The shovel bucket is fixedly connected to the connecting rod and is located in front of the grouting ring; The cleaning brush is fixedly connected to the connecting rod and located behind the grouting ring; When the connecting rod rotates forward along the wheel shaft until the bottom of the shovel hopper abuts against the masonry wall, the cleaning brush is spaced apart from the masonry wall, and the shovel hopper and grouting ring work simultaneously. When the connecting rod rotates backward along the wheel axis until the bottom of the cleaning brush abuts against the masonry wall, the shovel hopper is spaced apart from the masonry wall, and the cleaning brush and grouting ring work simultaneously.

[0009] Furthermore, the grouting ring has an opening, and mounting plates are fixedly connected to both sides of the opening. The mounting plates are detachably connected to the connecting rod.

[0010] Furthermore, the outer surface of the grouting ring is detachably fitted with a grouting sleeve.

[0011] Furthermore, the shovel bucket is fixedly connected to the connecting rod via a spring telescopic rod, which is an arc-shaped rod with the rotation center of the wheel axle as its center.

[0012] Furthermore, the handle includes a first handle and a second handle. When the connecting rod rotates forward along the wheel shaft until the bottom of the shovel hopper abuts against the masonry wall, the first handle is located in front of the connecting rod, making it easy to hold the first handle and pull forward; When the connecting rod rotates forward along the wheel shaft until the bottom of the shovel hopper abuts against the masonry wall, the second handle is located behind the connecting rod, making it easy to hold the second handle and push forward.

[0013] Furthermore, a third handle is fixedly connected between the ends of the first handle and the second handle to form a triangular handle structure, with the third handle perpendicular to the length direction of the connecting rod.

[0014] The beneficial effects of the above technical solution are: (1) The grouting ring of this utility model is coaxially wrapped around the middle of the wheel axle. Even if the grouting ring rotates and the working position of the grouting ring changes, it will not affect the grouting depth. The roller abuts against the masonry wall to form support. Even if the pressure of the worker on the masonry wall changes, it will not affect the grouting depth. It can effectively solve the problem that the grouting process is highly dependent on the experience and force control of the construction personnel, which can easily cause inconsistent pressing depth and inconsistent joint shape, and ensure the appearance quality of the finished product.

[0015] (2) This utility model integrates the three functions of scraping, compacting and cleaning into one tool. By simply switching the usage mode, the function mode can be switched, compressing the three process steps of scraping, compacting and cleaning into two, and forming a secondary grouting effect on the mortar joint. This can effectively solve the problem of low operation efficiency caused by repeatedly changing tools during the construction process, and effectively improve the construction efficiency.

[0016] (3) When the cleaning brush and the grouting ring work at the same time, the cleaning brush located at the rear will immediately clean the wall surface after the second grouting to remove excess grout, laitance or dust, keep the brick surface clean. The cleaning operation and the grouting operation are integrated into one operation, which can clean the residual mortar after grouting in time, and prevent the problem of the initial setting of mortar residue and the difficulty of cleaning. It avoids the situation of the initial setting of mortar causing pollution of the brick surface and the difficulty of later repair. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This example aims to provide a masonry grouting tool, which is mainly used in the grouting process of masonry walls, addressing the problems of needing to repeatedly change tools, inconsistent pressing depth, and separation of cleaning and grouting operations.

[0019] A type of masonry grouting tool, such as Figure 1 and Figure 2 It includes a connecting rod 1, an axle 2, rollers 3, a grouting ring 4, a shovel 5, and a cleaning brush 6. One end of the connecting rod 1 is fixedly connected to the axle 2, and rollers 3 are rotatably mounted on both ends of the axle 2. The rollers 3 are symmetrically installed on both sides of the connecting rod 1. The rollers 3 are used to roll along the masonry wall surface, providing lateral support for the tool and facilitating its movement.

[0020] The grouting ring 4 is detachably connected to the connecting rod 1 and coaxially surrounds the center of the wheel axle 2. The grouting ring 4 is located between the two rollers 3 and is used to grout and compact the mortar joints to form a concave arc-shaped groove. The diameter of the grouting ring 4 is larger than the diameter of the roller 3, and the grouting depth depends on the difference between the radius of the grouting ring 4 and the radius of the roller 3. Because the grouting ring 4 is coaxially surrounded by the center of the wheel axle 2, even if the grouting ring 4 rotates, causing a change in its working position, it will not affect the grouting depth. The rollers 3 abut against the masonry wall surface to provide support; even if the pressure applied by the worker to the masonry wall changes, it will not affect the grouting depth. This effectively solves the problem that the grouting process is highly dependent on the experience and force control of the construction personnel, easily leading to inconsistent pressing depth and inconsistent joint shape, thus ensuring the quality of the finished product's appearance.

[0021] The grouting ring 4 has an opening, and mounting plates 8 are fixedly connected to both sides of the opening. The mounting plates 8 and the connecting rod 1 have corresponding bolt holes and are detachably connected by bolt kits. Different grouting effects can be achieved by replacing the grouting rings 4 with different diameters.

[0022] The hopper 5 is fixedly connected to the connecting rod 1 and is located in front of the grouting ring 4, with the forward direction referenced. Figure 2 To the right, the cleaning brush 6 is fixedly connected to the connecting rod 1 and located behind the grouting ring 4.

[0023] This example has two usage modes, such as Figure 3 When the connecting rod 1 rotates forward along the axle 2 until the bottom of the shovel 5 abuts against the masonry wall, the cleaning brush 6 is spaced apart from the masonry wall. The shovel 5 and the grouting ring 4 work simultaneously, with the tools moving forward to the right. The shovel 5 scrapes away excess mortar protruding from the brick joints for pretreatment, ensuring the mortar in the gaps is flat and that the mortar joints after grouting and compaction have uniform density. The grouting ring 4 grouts and compacts the flattened mortar joints, forming a concave arc-shaped groove.

[0024] like Figure 3 When the connecting rod 1 rotates backward along the wheel axle 2 until the bottom of the cleaning brush 6 abuts against the masonry wall, the shovel hopper 5 is spaced apart from the masonry wall. The cleaning brush 6 and the grouting ring 4 work simultaneously, and the tools move forward to the right. First, the grouting ring 4 performs secondary grouting on the mortar joints, further compacting the parts that were not sufficiently compacted and contained air bubbles during the previous grouting, improving fullness and crack resistance. Subsequently, the cleaning brush 6, located behind, immediately cleans the wall surface to remove excess filler, laitance, or dust, keeping the brick surface clean. The cleaning operation and grouting operation are integrated into one operation, which can promptly clean the residual mortar after grouting, preventing the problem of mortar residue setting and subsequent cleaning difficulties, and avoiding the situation of mortar initial setting causing contamination of the brick surface and difficulty in later repair.

[0025] This embodiment integrates the three functions of scraping, compaction, and cleaning into one tool. By simply switching the usage mode, the function mode can be switched, compressing the three process steps of scraping, compaction, and cleaning into two. This can effectively solve the problem of low operation efficiency caused by repeatedly changing tools during the construction process, and effectively improve the construction efficiency.

[0026] The other end of the connecting rod 1 is fixedly connected to a handle 7 for holding and using the tool. This is to accommodate two different usage modes, such as... Figures 1 to 4 The handle 7 includes a first handle 701 and a second handle 702. For example... Figure 3 When the connecting rod 1 rotates forward along the axle 2 until the bottom of the shovel 5 abuts against the masonry wall, the first handle 701 is located in front of the connecting rod 1, making it easy to grip the first handle 701 and pull it forward; Figure 4 When the connecting rod 1 rotates forward along the wheel axle 2 until the bottom of the shovel 5 abuts against the masonry wall, the second handle 702 is located behind the connecting rod 1, making it easy to hold the second handle 702 and push it forward.

[0027] Example 2 is basically the same as Example 1, except that it is equipped with a grout sleeve 9 and a spring telescopic rod 10.

[0028] In this embodiment, as Figure 5 The outer surface of the grouting ring 4 is detachably fitted with a grouting sleeve 9, which is a rubber sleeve with an opening. The grouting sleeve 9 covers and is detachable from the grouting ring 4. By replacing the grouting sleeve 9 with different thicknesses, different grouting depths and grouting effects can be obtained.

[0029] like Figure 5 The shovel 5 is fixedly connected to the connecting rod 1 via a spring telescopic rod 10. The spring telescopic rod 10 is an arc-shaped rod with the rotation center of the wheel axle 2 as its center, so that the worker can apply force and pressure to the shovel 5 through the handle 7 to ensure that the shovel 5 fits tightly against the wall and improves the shoveling effect.

[0030] Example 3 is basically the same as Example 1, except that the structure of the handle 7 has been improved.

[0031] In this embodiment, as Figure 6 A third handle 703 is fixedly connected between the ends of the first handle 701 and the second handle 702 to form a triangular handle structure. The third handle 703 is perpendicular to the length direction of the connecting rod 1, so that it can be used by holding the third handle 703 in both usage modes.
