Description

Technical Field

[0001] This utility model relates to the field of brick-concrete composite sidewalk construction technology. Background Technology

[0002] Regarding the structure of sidewalks for non-motorized vehicle lanes, existing technical manuals categorize them into three main types: the first type uses a combination of paving stones and tactile paving stones; the second type combines concrete sidewalks with tactile paving stones; and the third type combines plastic sidewalks with tactile paving stones. This utility model focuses on a technological innovation in the construction process of the second type of structure.

[0003] The existing construction process for sidewalks combining concrete sidewalks and tactile paving bricks is as follows: First, the tactile paving bricks are laid. Cement mortar is used to fix the tactile paving bricks on the coarse sand concrete layer. After it solidifies, the concrete on both sides is poured. During the concrete pouring process, a vibrator is used to compact the concrete. During the compaction process, the vibrator is easy to hit the tactile paving bricks, causing the tactile paving bricks to shift and move, thus affecting the final construction effect.

[0004] Meanwhile, during the above process, concrete will splash onto the tactile paving bricks, requiring secondary cleaning and increasing costs.

[0005] Meanwhile, during the above process, the concrete poured in the second phase forms rough edges with an interlocking structure on both sides of the tactile paving bricks, which affects the aesthetics of the construction. Utility Model Content

[0006] Based on the aforementioned technical deficiencies, this utility model provides a high-quality construction structure for brick-concrete composite sidewalks. By implementing this structure, the problems of misaligned and unsightly tactile paving bricks during construction can be solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-quality construction structure for a brick-concrete sidewalk includes curbs on both sides and a coarse sand concrete layer in the area between the curbs. The structure is characterized by a formwork assembly supporting the top of the coarse sand concrete layer, wherein the formwork assembly extends along the sidewalk direction, and the area between the formwork assembly and the curbs is filled with concrete.

[0008] The template component has height and width adjustment functions.

[0009] The template assembly includes a template and a turnbuckle assembly. The turnbuckle assembly consists of a turnbuckle and bolts on both sides. The bolts on both sides have opposite spiral directions and are vertically fixed to the templates on both sides by welding. By rotating the turnbuckle, the distance between the two parallel templates can be controlled, thereby achieving the purpose of micro-adjustment of the width.

[0010] It also includes angle steel, wherein the angle steel is provided with an elongated hole in the vertical direction, which cooperates with the screw fixed on the lower edge of the template and is fixed with a nut for adjusting the elevation of the template.

[0011] The template can be a wooden template, a steel template, or an aluminum template.

[0012] The elevation of the template in the template assembly is level with the line connecting the tops of the curb stones on both sides.

[0013] The beneficial effects of this utility model are: The implementation of this construction structure allows for the process of pouring concrete first and then laying tactile paving bricks. This process completely changes the drawbacks of the traditional method of laying bricks first and then pouring concrete, and solves the technical defects of tactile paving bricks being misaligned and unsightly in the traditional process.

[0027] The brick-concrete sidewalk consists of, from bottom to top, rammed earth, a 20cm lime-stabilized soil layer, a 20cm coarse sand concrete layer, a 15cm C15 cement mortar layer, and tactile paving bricks. The tactile paving bricks are laid in the designed locations on the sidewalk, such as in the center or slightly to the outer edge, as shown in the reference. Figure 11 and Figure 12 .

[0028] The construction process is as follows: The first step involves rapid compaction, followed by manual spreading of lime, mixing with a road mixer, leveling, and compaction with a road roller to form lime-stabilized soil. Next, a 20cm layer of coarse sand concrete is poured using commercial concrete. This results in a 20cm coarse sand concrete layer. (This step is referenced in the original text.) Figure 7 .

[0029] The second step involves supporting the formwork assembly 20 above the 20cm coarse sand concrete layer 10 according to the design drawings and elevation. This formwork assembly is used to reserve space for the laying of tactile paving bricks, forming a secondary laying space. Adjusting the elevation and width of the formwork during the support process ensures that the design requirements are met. This step is referenced... Figure 8 .

[0030] The third step involves pouring C15 cement mortar, mixed on-site, into the space between the template and the curbstone. The C15 mortar is mixed on-site using a truck-mounted mixer, with an extended chute (basket-shaped) at the mixer's outlet, featuring angle adjustment. This can be referenced from the chutes on existing commercial concrete mixer trucks. Then, an improved concrete plate vibratory leveler is used to compact and smooth the poured concrete. After curing and hardening, the concrete pavement (30) is formed. (Refer to...) Figure 9 .

[0031] In this step, manual spreading, compaction, and smoothing are used. Mechanized methods can also be used as needed, and these are all within the scope of protection of this utility model.

[0032] Fourth, after the concrete pavement 30 has cured and hardened, remove the aforementioned formwork assembly 20, as per [reference needed]. Figure 10 The tactile paving bricks (40mm) are then laid. The specific laying method is as follows: Use cement mortar to lay the tactile paving bricks within the pre-reserved installation space in the aforementioned concrete pavement, level the surface, fill the joints, and then cure. Once curing is complete, all work is finished. (Refer to...) Figure 11 .

[0033] In the above process, expansion joints 31 can be set in the concrete pavement 30 as needed. These expansion joints can be formed by secondary cutting with a cutting machine, or by pre-setting partitions during the concrete pouring process. (See reference...) Figure 3 .

[0034] Furthermore, a template component 20 with an optimal structure, referenced Figures 4 to 6 The template assembly includes template 21, turnbuckle assembly 22, angle steel 23, and connecting plate 24. Template 21 is made of 3mm thick thin steel plate through welding and bending, similar to existing building templates. The outer side of the template is a flat release surface, coated with a release agent. A series of screws are welded along the length of the template at its lower edge, vertically fixing it to the inner side of the template, and the angle steel 23 is secured with nuts. The angle steel has elongated holes machined along its height direction, with the holes perpendicular to its length. The height of the template can be adjusted by loosening and tightening the nuts. Specifically, during the formwork erection process, the angle steel is pressed against the foundation, and the height of the upper edge of the template is adjusted. After adjustment, the upper edge of template 21 is at the same height as the curb stones 00 on both sides. Simultaneously, the width is adjusted using a turnbuckle assembly. Specifically, the turnbuckle assembly 22 consists of a turnbuckle and bolts on both sides. The bolts on both sides have opposite spiral directions, and the bolts on both sides are vertically fixed to the templates on both sides by welding. By rotating the turnbuckle, the distance between the two parallel templates is controlled, thereby achieving the purpose of micro-adjustment of the width.

[0035] Therefore, this template component has fine-tuning functions in the elevation and width directions.

[0036] High-quality construction structure for brick-concrete composite sidewalks, reference Figure 1 and Figure 2 The structure includes curb stones on both sides and layers of compacted subgrade, lime-stabilized soil, and coarse sand concrete arranged sequentially from bottom to top in the area between the curb stones. A formwork assembly 20 is installed on top of the coarse sand concrete layer. Multiple sets of formwork assemblies extend along the sidewalk direction, and concrete is poured in the area between the formwork assembly and the curb stone.

[0037] The template components mentioned above have height and width adjustment functions.

[0038] The elevation of the template in the above template component is level with the line connecting the tops of the curb stones on both sides.

[0039] After demolding, the cast-in-place concrete and the tactile paving bricks to be installed are in a vertical position with no chipped corners, eliminating the need for secondary repairs and saving time and costs associated with secondary corner repair.

[0040] The template components are molded in one step, resulting in high dimensional accuracy.

[0041] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
