Description

Technical Field

[0001] This utility model relates to the field of sidewalk brick paving technology, and in particular to a standardized paving system for curved sidewalks. Background Technology

[0002] Sidewalk paving is a common construction activity in municipal and landscape engineering projects. Traditional paving methods typically use rectangular standard pavers arranged in a regular pattern, with staggered placement to enhance the overall stability and aesthetics. In actual projects, to adapt to road alignment or landscape design requirements, sidewalks often involve paving at curved corners. When paving such curved sections, each row of pavers needs to gradually turn with the curvature, meaning the angle between the pavers constantly changes. Therefore, standard pavers must be cut at an angle to accommodate the curved direction.

[0003] However, due to the staggered paving technique, small bricks are often cut into the curved center line area. These bricks not only disrupt the overall visual continuity of the paved surface, affecting its aesthetics and uniformity, but also, due to their small size, have insufficient contact area with the base layer, resulting in poor adhesion. Under long-term load and external environmental influences, they are prone to loosening and falling off, which in turn affects the functionality and durability of the sidewalk, leading to problems such as increased maintenance frequency and shortened lifespan. Summary of the Invention

[0004] This utility model addresses the aforementioned deficiencies in the prior art by providing a standardized paving system for curved sidewalks. The technical solution includes: a standardized paving system for curved sidewalks comprising two types of bricks: rectangular standard bricks and trapezoidal standard bricks. Rectangular standard bricks are used in regular areas and are laid on the base layer in a regular staggered manner. Trapezoidal standard bricks are specifically used in curved areas, and their structure is defined as follows: the plane containing the hypotenuse of the trapezoidal standard brick is the side surface, and the plane containing the upper and lower bases of the trapezoid is the base surface. The included angles between the side surface and the two base surfaces are 95 degrees and 85 degrees, respectively, so that a single trapezoidal standard brick can provide a 10-degree curved turning angle. By continuously laying N columns of the trapezoidal standard bricks, an N*10-degree curved turning paving can be achieved.

[0005] In a preferred embodiment of the present invention, it further includes: a positioning component for positioning and laying rectangular standard bricks and trapezoidal standard bricks. The positioning component includes: a mounting arm; a rotating arm rotatably connected to the mounting arm, forming a T-shaped structure; a pressure plate slidably connected to the mounting arm, which locks the rotating shaft of the rotating arm by applying downward pressure; and a fixing screw that passes through the pressure plate and is threaded to the mounting arm.

[0006] In a preferred embodiment of the present invention, it further includes: a contact plate, fixedly connected to the bottom of the pressure plate; and a mating plate, fixedly connected to the rotating shaft of the rotating arm. The contact plate and the mating plate are provided with interlocking annular corrugated grooves on their opposite surfaces.

[0007] In a preferred embodiment of the present invention, the invention further includes: a marker disposed on the rotating arm; and a pointer fixedly connected to the mounting arm, the pointer pointing in coordination with the marker to display the real-time angle between the rotating arm and the mounting arm.

[0008] In a preferred embodiment of the present invention, a protective cover is further included, which covers the fixing screw and is engaged with the pressure plate to prevent foreign objects such as mortar and dust from entering the fixing screw.

[0009] In a preferred embodiment of the present invention, the brick surface of the trapezoidal standard brick is pre-cut with grooves to indicate the marking positions for cutting at different sizes.

[0010] Compared with existing technologies, this utility model has the following advantages: By using standardized trapezoidal standard bricks at appropriate angles, it aims to achieve complete adaptation in curved areas, avoiding the presence of numerous small-sized bricks in these areas, thus ensuring the visual continuity and uniformity of the paved surface; all bricks are of standardized size, with sufficient contact area and uniform adhesion, which improves the overall stability and service life of the paved layer; and by using trapezoidal and rectangular standard bricks with preset angles in combination, the construction process is simplified, reducing paving difficulty and facilitating rapid and standardized construction. The positioning component ensures the paving accuracy and consistency of the bricks by precisely determining the brick laying angle, thus guaranteeing the overall aesthetics and structural integrity of the paved surface; the positioning component provides standard space for mortar filling by fixing the uniform spacing between bricks, ensuring effective adhesion of all bricks and improving the durability and quality of the paved layer; the positioning component simplifies the brick laying layout process, making the paving operation more convenient and faster, and significantly improving construction accuracy and consistency. The corrugated groove meshing design of the contact plate and the mating plate will achieve high-rigidity surface contact locking, completely avoiding possible angular micro-slippage under construction disturbance, making the use of the positioning component more stable and reliable, and eliminating the need for repeated checks and adjustments of the angle during the laying process.

[0018] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0019] Example: A standardized paving system for curved sidewalks, see reference. Figures 1-3 The system includes two types of bricks: rectangular standard bricks 2 and trapezoidal standard bricks 3. Rectangular standard bricks 2 are used in regular areas and are laid on the base layer 1 in a regular staggered manner. Trapezoidal standard bricks 3 are specifically used in curved areas. Their structure is defined as follows: the plane containing the trapezoidal hypotenuse of the trapezoidal standard brick 3 is the side surface 302, and the plane containing the upper and lower bases of the trapezoid is the bottom surface 303. The included angles between the side surface 302 and the two bottom surfaces 303 are 95 degrees and 85 degrees, respectively. This angle design allows a single trapezoidal standard brick 3 to provide a 10-degree curved turning angle. In actual paving, by configuring N columns of trapezoidal standard bricks 3, an N*10-degree curved turning paving can be achieved.

[0020] For example, when laying a 30-degree curved sidewalk, three rows of trapezoidal standard bricks (3) are required: First, align and position the middle row along the center line of the curve, then arrange the other two rows symmetrically on both sides; after laying the curved area, use these three rows of trapezoidal standard bricks as a reference, and then extend to both sides to lay rectangular standard bricks (2). This method is simple to operate, has high paving efficiency, and produces a neat and beautiful overall effect with reliable structural quality.

[0021] By using standardized trapezoidal standard bricks 3 at the same angle, the aim is to achieve complete adaptation in curved areas, avoiding the appearance of a large number of small bricks in curved areas, thereby ensuring the visual continuity and uniformity of the paving surface; all bricks are of standardized size, with sufficient contact area and uniform adhesion, which will improve the overall stability and service life of the paving layer; and by using trapezoidal standard bricks 3 with preset angles in combination with rectangular standard bricks 2, the construction process is simplified, the paving difficulty is reduced, and it is conducive to achieving fast and standardized construction.

[0022] See Figure 2 , Figure 4 and Figure 5 It also includes: a positioning component 4, used for quickly positioning and laying rectangular standard bricks 2 and trapezoidal standard bricks 3. The positioning component 4 includes: a mounting arm 401; a rotating arm 402, which is rotatably mounted on the mounting arm 401 and forms a T-shaped structure; a pressure plate 403, which is slidably mounted on the mounting arm 401 and locks the rotating shaft of the rotating arm 402 by applying downward pressure, thereby fixing the angle between the rotating arm 402 and the mounting arm 401; and a fixing screw 404, which passes through the pressure plate 403 and is threaded onto the mounting arm 401. When tightened, the screw presses the pressure plate 403 to lock the angle.

[0023] When tiling, follow the construction sequence of first tiling the curved sections and then the straight sections: When laying trapezoidal standard bricks 3 in the arc section, firstly, adjust the angle between the rotating arm 402 and the mounting arm 401 in the positioning component 4 to 85 degrees, and then adjust the angle to both sides of the rotating arm 402 in two ways. Secondly, determine the number of columns of trapezoidal standard bricks 3 according to the arc corner planning of the sidewalk, and ensure that the center line is aligned with the center line of the arc corner. After determining the paving range and the position of the reference brick, place the positioning component 4 with the preset 85-degree angle close to the two 85-degree angles of the positioned trapezoidal standard bricks 3. Then, when laying adjacent bricks, make its side close to the other side of the rotating arm 402. At this time, a 10-degree angle is naturally formed between the brick and the mounting arm 401, thereby ensuring that the spacing between the bricks is consistent. Similarly, when laying rectangular standard bricks 2 on a straight section, the angle between the rotating arm 402 and the mounting arm 401 is first adjusted to 90 degrees; then, during the laying process, the horizontally adjacent rectangular standard bricks 2 are separated and positioned by the rotating arm 402, and the vertically adjacent rectangular standard bricks 2 are separated and positioned by the mounting arm 401, thereby achieving rapid and uniform determination of the brick angles and spacing.

[0024] Positioning component 4 ensures the accuracy and consistency of brick laying by precisely determining the brick laying angle, thus guaranteeing the overall aesthetics and structural integrity of the paved surface. Positioning component 4 provides standard space for mortar filling by fixing the uniform spacing between bricks, ensuring effective bonding of all bricks and improving the durability and quality of the paved layer. Positioning component 4 simplifies the brick laying layout process, making the paving operation more convenient and faster, and significantly improving construction accuracy and consistency.

[0025] like Figure 6 As shown, it also includes: a contact plate 5, fixedly installed on the bottom of the pressure plate 403; and a mating plate 6, fixedly installed on the rotating shaft of the rotating arm 402. The opposing surfaces of the contact plate 5 and the mating plate 6 are provided with interlocking annular corrugated grooves. When the fixing screw 404 is tightened and the pressure plate 403 slides downwards, the corrugated grooves of the contact plate 5 and the mating plate 6 tightly engage, forming a radial interlock, thereby more stably locking the relative angle between the rotating arm 402 and the mounting arm 401. The corrugated groove interlocking design of the contact plate 5 and the mating plate 6 achieves high-rigidity surface contact locking, completely avoiding possible micro-slippage of the angle under construction disturbances, making the use of the positioning component 4 more stable and reliable, eliminating the need for repeated checks and adjustments of the angle during the installation process.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, it also includes: label 7, located on the rotating arm 402; pointer 8, fixedly installed on the mounting arm 401, the pointer 8 pointing in accordance with label 7, to intuitively and quickly display the real-time angle between the rotating arm 402 and the mounting arm 401, facilitating the operator to precisely adjust the positioning component 4 to the different working states required for paving rectangular standard bricks 2 or trapezoidal standard bricks 3; and protective cover 9, covering the fixing screw 404 and engaging with the pressure plate 403, used to prevent mortar, dust, and other foreign objects from entering the fixing screw 404, ensuring fixation. The screw 404 has a normal tightening and loosening function, thereby maintaining the reliability and service life of the positioning component 4 throughout the construction cycle; the trapezoidal standard brick 3 has multiple grooves 10 pre-cut on its surface 301 to indicate the calibration position for size cutting at a specific angle. When encountering curved road sections with extremely small turning radii or narrow paving areas, the standard-sized trapezoidal standard brick 3 can be cut into smaller specifications along the grooves 10, meeting the paving requirements of special working conditions while maintaining the standard turning angle, thereby enhancing the overall adaptability of the system.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
