Description

Technical Field

[0001] This utility model relates to the field of geotextile positioning technology, specifically to a geotextile positioning device for the curing of concrete guardrails. Background Technology

[0002] The maintenance of bridge concrete railings is crucial to ensuring their durability and safety. Maintenance requires a multi-pronged approach, including early moisture retention, crack control, and waterproofing, combined with regular inspections and maintenance to guarantee long-term safety and durability. The high temperatures, dryness, and heavy rainfall of summer place even greater demands on the maintenance of bridge concrete railings. Summer maintenance is vital for ensuring their durability, safety, and cost-effectiveness. By implementing measures such as moisture retention, temperature control, waterproofing, and rust prevention, the challenges of high temperatures, heavy rainfall, and ultraviolet radiation in summer can be effectively addressed, extending the service life of the railings and ensuring traffic safety.

[0003] High-temperature moisturizing curing in summer is extremely important for concrete strength and early crack control. Traditional moisturizing curing uses a process of applying a thin film or geotextile to the surface of the crash barrier and sprinkling water to keep it moist. However, due to the influence of the external environment, the geotextile is prone to not adhering to the surface of the barrier under the action of wind and other forces, resulting in poor moisturizing curing effect. Utility Model Content

[0004] This utility model provides a geotextile positioning device for the curing of concrete guardrails, which can overcome some or all the defects of the prior art.

[0005] According to the present invention, a geotextile positioning device for curing concrete guardrails includes a device body, the device body includes a rotating shaft, and a first positioning member and a second positioning member are provided at the rotating shaft and are hinged to each other. The first positioning member has a first fitting part that fits against the outer wall of the concrete guardrail, and the second positioning member has a second fitting part that fits against the inner wall of the concrete guardrail.

[0006] Counterweights are provided at both the first and second positioning parts. The counterweights are used to provide a tendency for the first and second positioning parts to rotate in opposite directions along the axis of rotation, so as to achieve the self-adhesion of the first fitting part with the outer wall of the concrete guardrail and the second fitting part with the inner wall of the concrete guardrail.

[0007] This disclosure discloses a geotextile positioning device for the curing of concrete guardrails. By attaching the first fitting part of a first positioning member to the outer wall of the concrete guardrail and the second fitting part of a second positioning member to the inner wall of the concrete guardrail, the geotextile covering the guardrail is fixed, preventing it from failing to adhere to the guardrail surface due to external environmental influences (such as wind). Simultaneously, counterweights at the first and second positioning members ensure that the first and second fitting parts automatically adhere to the inner and outer walls of the concrete guardrail, resulting in a tight coverage of the geotextile on the guardrail surface. This improves the moisture retention and curing effect. The self-adhesive method eliminates the need for frequent manual adjustments, simplifying the operation process and improving construction efficiency.

[0008] Understandably, the design of the first and second bonding parts allows the device to better adhere to the surface of the concrete guardrail, improving the positioning effect of the geotextile or film.

[0009] Preferably, a first fastening portion is formed at the top of the first fitting portion, and a second fastening portion is formed at the top of the second fitting portion. The first fastening portion and the second fastening portion together form a mating portion that mates with the top wall of the concrete guardrail; wherein, the pivot is located in the middle of the mating portion.

[0010] The first and second bonding parts together form a mating part that cooperates with the top wall of the concrete guardrail. This allows for further restraint of the geotextile from the top wall of the concrete guardrail. Together with the first and second bonding parts, it achieves omnidirectional positioning of the three surfaces of the concrete guardrail (outer side wall, inner side wall, and top wall), enhancing the stability of the geotextile. This allows the geotextile to be more firmly fixed to the surface of the concrete guardrail, making it less prone to displacement due to external factors (such as wind and rain erosion). This, in turn, improves the effect of moisture retention and curing, helps the hydration reaction inside the concrete to proceed fully, improves the strength and durability of the concrete, and better controls the generation of early cracks.

[0011] Preferably, the lengths of the first and second adhesive portions along the vertical direction are equal.

[0012] The above structure ensures that when the device is installed on a concrete guardrail, the forces exerted on both sides of the guardrail are balanced in the vertical direction, preventing the device from tilting or not fitting tightly due to one side being too long, thus ensuring that the device can be stably fixed on the concrete guardrail.

[0013] Preferably, both the first positioning element and the second positioning element are made of galvanized flat iron.

[0014] Due to the strength and rust resistance of galvanized flat iron, this device can be used for a long time without damage in harsh environments such as high temperatures and heavy rain in summer, reducing the need for frequent replacements due to device damage, lowering maintenance costs, and featuring lightweight, high strength, easy installation and disassembly, and resistance to rust.

[0015] Preferably, the counterweight is arranged in the shape of a sphere.

[0016] The above structure avoids uneven local stress caused by the irregular shape of the counterweight, thus better positioning the geotextile.

[0017] Understandably, spherical counterweights have a smaller drag coefficient. When subjected to wind, spherical counterweights experience less swaying and displacement, thus better maintaining the stability of the device and ensuring that the geotextile remains tightly attached to the concrete guardrail surface, thereby improving the moisture retention and maintenance effect.

[0020] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0021] Example 1

[0022] Please see Figures 1-2 This embodiment provides a geotextile positioning device for the curing of concrete guardrails, which includes a device body 100. The device body 100 includes a rotating shaft, and a first positioning member 110 and a second positioning member 120 are hinged to each other at the rotating shaft. The first positioning member 110 has a first fitting part 130 that fits against the outer wall of the concrete guardrail, and the second positioning member 120 has a second fitting part 140 that fits against the inner outer wall of the concrete guardrail.

[0023] Counterweights 150 are provided at both the first positioning member 110 and the second positioning member 120. The counterweights 150 are used to provide a tendency for the first positioning member 110 and the second positioning member 120 to rotate in opposite directions along the axis of rotation, so as to achieve the self-adhesion of the first fitting part 130 with the outer wall of the concrete guardrail and the second fitting part 140 with the inner wall of the concrete guardrail.

[0024] This disclosure discloses a geotextile positioning device for the curing of concrete guardrails. By attaching the first fitting portion 130 of the first positioning member 110 to the outer wall of the concrete guardrail and the second fitting portion 140 of the second positioning member 120 to the inner wall of the concrete guardrail, the geotextile covering the guardrail is fixed, preventing the geotextile from not adhering to the guardrail surface due to external environmental influences (such as wind). At the same time, the counterweights 150 set at the first positioning member 110 and the second positioning member 120 enable the first fitting portion 130 and the second fitting portion 140 to automatically adhere to the inner and outer walls of the concrete guardrail, so that the geotextile tightly covers the surface of the concrete guardrail, thereby improving the effect of moisture retention and curing. The self-adhesive method eliminates the need for frequent manual adjustments, simplifies the operation process, and improves construction efficiency.

[0025] Understandably, the arrangement of the first bonding part 130 and the second bonding part 140 allows the device to better adhere to the surface of the concrete guardrail, thereby improving the positioning effect of the geotextile or film.

[0026] In this embodiment, a first fastening part 210 is formed at the top of the first fitting part 130, and a second fastening part 220 is formed at the top of the second fitting part 140. The first fastening part 210 and the second fastening part 220 together form a mating part that mates with the top wall of the concrete guardrail; wherein, the pivot is located in the middle of the mating part.

[0027] The first and second bonding parts 210 together form a mating part that cooperates with the top wall of the concrete guardrail. This allows for further restraint of the geotextile from the top wall of the concrete guardrail. Together with the first and second bonding parts 130 and 140, it achieves all-round positioning of the three surfaces (outer side wall, inner side wall, and top wall) of the concrete guardrail, enhancing the stability of the geotextile. This allows the geotextile to be more firmly fixed to the surface of the concrete guardrail, making it less prone to displacement due to external factors (such as wind and rain erosion). This, in turn, improves the effect of moisture retention and curing, helps the hydration reaction inside the concrete to proceed fully, improves the strength and durability of the concrete, and better controls the generation of early cracks.

[0028] In this embodiment, the first bonding portion 130 and the second bonding portion 140 have the same straight length in the vertical direction.

[0029] The above structure ensures that when the device is installed on a concrete guardrail, the forces acting on both sides of the guardrail are balanced in the vertical direction, preventing the main body of the device from tilting or not fitting tightly due to one side being too long, thus ensuring that the device can be stably fixed on the concrete guardrail.

[0030] In this embodiment, both the first positioning element 110 and the second positioning element 120 are made of galvanized flat iron.

[0031] Due to the strength and rust resistance of galvanized flat iron, this device can be used for a long time without damage in harsh environments such as high temperatures and heavy rain in summer, reducing the need for frequent replacements due to device damage, lowering maintenance costs, and featuring lightweight, high strength, easy installation and disassembly, and resistance to rust.

[0032] In this embodiment, the counterweight 150 is spherical.

[0033] The above structure avoids uneven local stress caused by the irregular shape of the counterweight 150, thus better positioning the geotextile.

[0034] Understandably, the spherical counterweight 150 has a smaller wind resistance coefficient. When subjected to wind force, the spherical counterweight produces less swaying and displacement, which can better maintain the stability of the device, ensure that the geotextile is always tightly attached to the concrete guardrail surface, and improve the moisture retention and maintenance effect.

[0035] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0036] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
