Description

Technical Field

[0001] This utility model relates to the field of sidewalk brick paving operation technology, and in particular to a sidewalk brick paving positioning device. Background Technology

[0002] In the construction of municipal and landscape projects such as sidewalks and squares, the quality of paving bricks directly affects the aesthetics, safety, and structural durability of the overall project. Among these factors, the flatness of the paved surface, the verticality between adjacent bricks, and the uniformity of the brick joint width are the core technical indicators for evaluating construction quality.

[0003] Currently, to control the aforementioned indicators during construction, manual measurement and layout methods are commonly used, primarily in two forms: physical lines and laser measuring instruments. However, both methods have significant limitations: physical layout is time-consuming and requires continuous reliance on the line position as a reference during construction; any disturbance or displacement of the physical line by external forces will directly affect the positioning accuracy. While laser measuring instruments offer higher accuracy, they are expensive to purchase and are sensitive to environmental factors such as temperature, humidity, and vibration during use; in complex construction sites, environmental fluctuations can easily lead to increased measurement errors.

[0004] Since the above methods all have varying degrees of instability in accuracy, the paving work often needs to be interrupted frequently during construction for repeated measurement and correction, resulting in cumbersome operation procedures, poor construction continuity, and ultimately restricting the overall paving efficiency and the stability of quality control. Summary of the Invention

[0005] This utility model addresses the aforementioned deficiencies in the prior art by providing a fast and accurate positioning device for sidewalk brick paving, thereby overcoming the inherent defects of existing line-laying and positioning methods and achieving standardized and efficient construction.

[0006] The technical solution of this utility model is as follows: a sidewalk brick paving positioning device, comprising: a web plate, the length direction of which is defined as transverse and the width direction of which is defined as longitudinal; a long limb, which extends transversely along the web plate and whose thickness gradually decreases from the web plate to the distal end; a short limb, which extends in at least one longitudinal direction along the web plate and whose thickness gradually decreases from the web plate to the distal end, the thickness reduction being consistent with that of the long limb; and scale markings, which are set on the long limb and the short limb and arranged vertically.

[0007] In one embodiment, if the short limb is a unidirectional extending structure, the entire locking device will be in a right-angled T shape, which is used for paving operations on straight sections of sidewalks.

[0008] In one embodiment, the short limb is a bidirectional extension structure, which makes the overall positioning device cross-shaped, and the intersection angle between the long limb and the web is less than 180 degrees, providing a turning radius during the paving of the sidewalk for the paving operation of curved sidewalks.

[0009] In one embodiment, the locking device further includes: a fixing plate fixedly connected to the top of the web plate, having an insertion port thereon; and an operating block, which has a "Z" shaped structure and can be inserted into the insertion port to form a lever structure with the user's finger as a fulcrum, prying and disassembling the locking device.

[0010] In one embodiment, the surface of the operating block is provided with grooves to increase contact friction.

[0011] In one embodiment, the operating block has a hook opening for providing a suspension point.

[0012] In one embodiment, the positioning device further includes an anti-adhesion layer, wherein the surfaces of the web, long limbs and short limbs are provided with an anti-adhesion layer to prevent concrete mortar from adhering.

[0013] Beneficial effects: This utility model achieves unified control of brick joint width through the structural design of long and short limbs, and uses scale marking to ensure accurate paving elevation, thereby improving the overall construction quality; in addition, the recycling mechanism of this utility model reduces material consumption, replaces the traditional measurement and layout process, reduces labor costs, and shortens the construction cycle.

[0014] This utility model adopts two structural designs, T-shaped and cross-shaped, to adapt to the needs of straight and curved sidewalk paving respectively, thereby improving the versatility of this utility model; and the cross-shaped structure can automatically adjust the angle of the brick joints in the curved section by preset installation angle, reducing the complexity of brick paving alignment adjustment.

[0015] This utility model utilizes a lever structure design with a "Z"-shaped operating block and a fixing plate, along with an anti-stick layer, to achieve quick disassembly and cleaning. The design of the groove and hook on the operating block further optimizes the user experience. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the overall angled cross-shaped structure of this utility model.

[0017] Figure 2 This is a schematic diagram of the overall right-angled T-shaped structure of this utility model.

[0018] Figure 3 This is a top view of the present invention.

[0019] The markings in the diagram are: 1-stomach, 2-long limb, 3-short limb, 4-fixing plate, 5-insertion, 6-operating block, 7-gradation marking, 8-anti-adhesive layer, 9-groove, 10-hook opening. Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] Example 1: A sidewalk brick paving positioning device, such as Figure 1 and Figure 3 As shown, a sidewalk brick paving positioning device includes: a web plate 1, whose length direction is defined as transverse and whose width direction is defined as longitudinal, with a thickness of 5mm and a height of 100mm; a long limb 2, which extends transversely along the web plate 1, and whose thickness gradually decreases from the web plate 1 to the distal end, with a final thickness of 3mm; a short limb 3, which extends unidirectionally longitudinally along the web plate 1, making the positioning device as a whole a right-angled T-shape, suitable for straight sidewalk paving, and whose thickness gradually decreases from the web plate 1 to the distal end, with a final thickness of 3mm; and scale markings 7, which are set on the long limb 2 and the short limb 3 and arranged vertically.

[0022] During the paving of sidewalk bricks, this right-angled T-shaped positioning device is placed between two adjacent bricks. This positioning device will act as a gap separator during the paving operation. The short limb 3 controls the width of the horizontal brick joint, and the long limb 2 controls the width of the vertical brick joint. The final joint width will be uniformly controlled at 3mm. The height design of the web plate 1 makes this positioning device suitable for paving sidewalk bricks with a thickness of less than 80mm. The scale marking 7 will enable precise elevation adjustment during the paving operation.

[0023] The operation procedure of this positioning device is as follows: Place the first row of positioning devices at the predetermined position, lay the first row of sidewalk bricks, then place the next row of positioning devices and lay the corresponding row of sidewalk bricks; after the bricks in that row are positioned, remove the previous row of positioning devices and reuse them for the next row, repeating the above steps until the paving is completed. This process enables the cyclical reuse of this positioning device, which can replace the traditional measurement and layout process, achieving the effects of saving labor costs and accurately controlling the quality of brick joints.

[0024] like Figure 1 and Figure 2 As shown, this positioning device also includes: a fixing plate 4, which is fixedly installed on the top of the web plate 1 and has an insertion port 5; and an operating block 6, which has a "Z" shaped structure and can be inserted into the insertion port 5 to form a lever structure with the user's finger as the fulcrum, making it easy to pry and disassemble this positioning device and improving the ease of disassembly of this positioning device.

[0025] like Figure 1As shown, this positioning device also includes: a groove 9 on the surface of the operating block 6 to increase contact friction, making the disassembly operation more stable, avoiding slippage during disassembly, and improving the operational stability and safety of this positioning device; and a hook 10 on the operating block 6 to provide a hanging part, making it easy to store the operating block 6 and reducing the risk of loss.

[0026] like Figure 1 and Figure 2 As shown, this positioning device also includes an anti-adhesion layer 8. The surfaces of the web plate 1, the long limb 2 and the short limb 3 are all provided with an anti-adhesion layer 8, which can effectively prevent concrete mortar from sticking and make the cleaning operation after the positioning device is disassembled more convenient and efficient.

[0027] Example 2: As Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the short limb 3 has a bidirectional extension structure, making the entire positioning device cross-shaped; a 170-degree intersection angle is set between the long limb 2 and the web plate 1, providing a 10-degree turning radius for sidewalk paving operations, suitable for curved sidewalk paving. By presetting the arc angle between the long limb 2 and the web plate 1, the brick joint angle is automatically adjusted, simplifying the paving operation process for curved road sections.

[0028] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
