Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically to a standard tool for paving small stones. Background Technology

[0002] In the construction of gardens, squares, and other road surfaces, small stone paving is widely used due to its aesthetic appeal and durability. However, traditional paving methods mainly rely on construction workers to set up horizontal and vertical cross lines and manually place and adjust each stone. This method has the following significant drawbacks: 1. Due to the dimensional differences in the small stones themselves (often exceeding the ±1mm specification requirement), as well as errors in manual placement, the width of the gaps between the stones after paving varies, which seriously affects the visual quality.

[0003] 2. When curved paving is required, traditional stringing methods are difficult to form smooth arcs, often resulting in broken lines, stiff lines, and more difficult-to-control seam widths.

[0004] 3. Relying entirely on human eyesight and craftsmanship, adjusting piece by piece, the construction speed is slow, the skill requirements for workers are high, and it is difficult to guarantee the quality uniformity of large-scale paving.

[0005] Therefore, there is an urgent need in this field for a specialized tool that can effectively ensure uniform paving joint width, adapt to both straight and curved paving, and improve construction efficiency. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art and thus provide a standard tool for paving small stones.

[0007] A small stone paving tool includes two parallel longitudinal rods, multiple detachable transverse rods connected between the two longitudinal rods, and an adjustment device; The adjusting device is fixedly connected to the longitudinal member, and the adjusting device adjusts the curvature of the longitudinal member.

[0008] Furthermore, the adjusting device includes a transverse force-bearing member, a longitudinal force-bearing member, and a double-threaded sleeve; The double-threaded sleeve has internal threads with opposite directions on its two opposite sides. The longitudinal force-bearing member has an external threaded rod. A pair of longitudinal force-bearing members are threadedly connected to the double-threaded sleeve. One end of the longitudinal force-bearing member is connected to one end of the transverse force-bearing member, and the other end of the transverse force-bearing member is fixedly connected to the longitudinal member.

[0009] Furthermore, the transverse member is detachably connected to the longitudinal member via anchor bolts.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see Figures 1-2 A small stone paving tool includes two parallel longitudinal rods 2, multiple detachable transverse rods 1 connected between the two longitudinal rods 2, and an adjustment device. The multiple transverse rods 1 and longitudinal rods 2 form multiple paving cells. The adjusting device is fixedly connected to the longitudinal rod 2, and the adjusting device adjusts the bending arc of the longitudinal rod 2.

[0028] The adjustment device includes a transverse force-bearing member 4, a longitudinal force-bearing member 5, and a double threaded sleeve 6; The double-threaded sleeve 6 has internal threads with opposite directions on its two opposite sides. The longitudinal force-bearing member 5 has an external threaded rod. A pair of longitudinal force-bearing members 5 are threadedly connected to the double-threaded sleeve 6. The longitudinal force-bearing member 5 is connected to one end of the transverse force-bearing member 4. The other end of the transverse force-bearing member 4 is fixedly connected to the longitudinal member 2. By rotating the double-threaded sleeve 6, the longitudinal force-bearing member 5 can move inward or outward at the same time. While moving, the longitudinal member 2 is bent, thereby adjusting the curvature.

[0029] The transverse member 1 is detachably connected to the longitudinal member 2 by anchor bolts 3. Other forms of detachable connection can also be used, such as a trapezoidal groove on the longitudinal member 2 and a trapezoidal protrusion on the transverse member 1. The trapezoidal protrusion and the trapezoidal groove are detachably connected. Any other detachable connection form that meets the requirements of this application scenario is acceptable.

[0030] There are two adjustment devices, and the two adjustment devices are fixedly connected to the two longitudinal rods 2 respectively.

[0031] The transverse members 1 are set in a total of 7, which divide the device into 6 paving compartments. The specific number can be adjusted according to the needs.

[0032] The transverse member 1 is an irregularly shaped member. By setting multiple irregularly shaped members, the paving grid formed between the irregularly shaped members and between the irregularly shaped members and the longitudinal member 2 can be transformed into a non-traditional standard square structure. For example, the paving grid can be triangular, prismatic, trapezoidal or other shapes to meet different paving requirements under different conditions. The specific shape of the transverse member 1 needs to be designed according to the paving pattern requirements. The connection method is the same as the connection method described above, and will not be repeated here.

[0033] The longitudinal member 2 is specifically a steel plate with a length of 150cm, a width of 8cm, and a thickness of 1cm. The transverse member 1 is specifically a steel plate with a width of 8cm and a thickness of 1cm, but can also be adjusted according to specific actual needs.

[0034] The process of using the small stone paving tool is as follows: Step 1: Conduct longitudinal and transverse measurements and mark out the paving area according to site requirements; Step 2: Clean the base layer, ensuring the surface is moist and free of dust; Step 3: Lay a 1:3 dry-mixed cement mortar bonding layer; Step 4: Pour 1:1 cement grout to cover the entire surface; Step 5: Assemble and place the small stone paving tools. If the paving edge is curved, turn the double threaded sleeve 6 to bend the longitudinal rod 2 to the appropriate angle. Align the two longitudinal rods 2 with the line. If there are paving areas with graphic requirements, or if non-standard or irregular small stones are to be laid, the irregular rods need to be replaced in advance. Step Six: Place the small stones one by one into the paving grid, and gently press them against the inner wall of the paving grid; Step 7: Use a rubber mallet to compact and flatten the small stones, making their top surface flush with or slightly lower than the top surface of the tool; Step 8: Lift the tool vertically upwards and move it to the next work station to repeat the operation until the laying is completed.

[0035] This small stone paving tool divides the paving area into multiple paving compartments using longitudinal and transverse rods. Each paving compartment precisely positions and limits the size of each group of small stones, ensuring that the gap width between the small stones remains consistent. This completely eliminates the random errors caused by manual placement and the influence of dimensional differences in the stones themselves, resulting in a paving effect that is straight, uniform, and neat.

[0036] This small stone paving tool, through its adjustment device, can apply a controllable curvature to the rigid longitudinal rods, enabling them to closely conform to the curved boundary stones or the designed lines, achieving a uniform joint width and smooth line in curved paving.

[0037] This small stone paving tool adopts a modular, group-based paving mode, which can accurately pave one paving cell at a time, saving the time of repeatedly adjusting the joints of each stone, greatly improving the paving speed and reducing the requirements for worker skill.

[0038] This small stone paving tool mainly uses common standard steel plates and detachable fasteners. It has a sturdy and durable structure, low manufacturing cost, and detachable connection for easy transportation and storage. It is also easy to operate.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
