Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a guardrail construction insulation device. Background Technology

[0002] In the construction of cement concrete structures, guardrails, as important traffic safety facilities, directly affect the overall safety performance and service life of road projects due to their construction quality. Especially in the low-temperature environment of winter, the hydration reaction rate of concrete decreases significantly, severely impacting its strength development and durability.

[0003] However, the construction of concrete guardrails in winter currently faces severe technical challenges. When encountering sustained low temperatures, large temperature differences between day and night, or inadequate curing measures, problems such as surface freezing and impeded internal moisture migration can easily occur, leading to quality defects in the guardrail structure, such as early cracking and insufficient strength. Once concrete quality defects form, they not only affect the appearance and functionality of the guardrail but also significantly reduce its impact resistance and service life.

[0004] Traditional heat preservation and moisture retention methods have limited effectiveness under winter construction conditions. Simple covering measures are insufficient to maintain a suitable hydration environment for concrete, forcing construction companies to take emergency measures such as extending the formwork removal time or localized heating. However, these temporary treatments not only significantly increase construction costs but may also induce thermal stress between the inside and outside of the concrete due to uneven temperature control, further exacerbating the risk of structural cracking.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] Firstly, see Figures 1-4 An embodiment of this application provides a guardrail construction insulation device, including a telescopic frame 1 and an insulation mechanism 2. The telescopic frame 1 includes two first frames 11, multiple second frames 12, and multiple telescopic connecting components 13. The multiple second frames 12 are sequentially arranged between the two first frames 11 along a first direction. The first frames 11 and their connected second frames 12 are all connected by the telescopic connecting components 13, so that the first frames 11 and their connected second frames 12 are relatively close or far apart. The second frames 12 and their connected second frames 12 are all connected by telescopic components. The connecting components 13 are connected so that the second frame 12 is relatively close to or far away from the second frame 12 to which it is connected; the heat preservation mechanism 2 includes a housing 21, a rotating shaft 22 and a heat preservation film 23. The housing 21 is fixed to one of the first frames 11, the rotating shaft 22 is rotatably disposed inside the housing 21, and the heat preservation film 23 is retractably wound on the rotating shaft 22. The housing 21 has a stretching opening, through which the heat preservation film 23 can extend. The heat preservation film 23 extends along a first direction and is fixed to another first frame 11 so that the heat preservation film 23 covers the entire telescopic frame 1.

[0041] The guardrail construction insulation device provided in this embodiment achieves flexible coverage of the guardrail construction area through a telescopic frame structure. Multiple frames and telescopic connecting components 13 work together to expand and contract the entire device, adapting to construction areas of varying lengths. An insulation film 23 covers the entire telescopic frame 1, achieving sealing and insulation of the construction area and effectively maintaining stable internal temperature. The winding and stretching design of the insulation film 23 also enables rapid laying and retraction. The rotation of the pivot 22 achieves automatic expansion and contraction of the insulation film 23, reducing manual operation time. Furthermore, the synergistic effect of the frame and insulation mechanism 2 achieves temperature control and protection of the construction environment, improving construction efficiency and quality in winter.

[0042] In this embodiment, the first direction is the length direction of the guardrail construction insulation device.

[0043] like Figures 1-4As shown, in some embodiments, the heat preservation mechanism 2 further includes a fixing component 24, which includes a fixing seat 241. The fixing seat 241 is fixed to the first frame 11 away from the housing 21. The fixing seat 241 is provided with a slot. A snap-fit ​​member 242 is fixedly provided on the protruding end of the heat preservation film 23. The snap-fit ​​member 242 can snap into the slot.

[0044] The fixing seat 241 on the frame cooperates with the snap-fit ​​component 242 at the end of the insulation film 23, enabling the insulation film 23 to be easily tensioned and fixed, ensuring the efficiency of the covering operation. The cooperation structure between the slot and the snap-fit ​​component 242 ensures the stability of the insulation film 23 in the unfolded state, effectively preventing displacement or detachment caused by wind or other external forces. The snap-fit ​​fixing method is achieved through mechanical snap-fit, without the need for additional tools or complicated operations, which can significantly improve the convenience of construction. At the same time, the fixing component 24 greatly improves the sealing effect of the protective film, ensuring that the edge of the insulation film 23 is tightly bonded to the frame, preventing heat loss and moisture escape, and creating a stable environment for the construction of concrete guardrails.

[0045] like Figures 1-2 As shown, in some embodiments, the insulation mechanism 2 further includes an automatic rewinding device, which is disposed inside the housing 21. The automatic rewinding device includes a torsion spring and a limiting component. One end of the torsion spring is fixed to the inner wall of the housing 21, and the other end is fixed to the rotating shaft 22. The limiting component includes a ratchet at the end of the rotating shaft 22 and an elastic pawl at the inner wall of the housing 21. When the insulation film 23 is pulled out, the pawl engages with the ratchet to prevent rotation. When the insulation film 23 is retracted, the release button is pressed, the pawl disengages from the ratchet, and the torsion spring drives the rotating shaft 22 to rotate, so that the insulation film 23 is automatically rewound.

[0046] Through the synergistic action of the torsion spring and the limiting component, the insulation film 23 can stably maintain its unfolded state when stretched, and can quickly and automatically roll up when retracted. When the insulation film 23 needs to be unfolded for coverage, the engagement mechanism of the pawl and ratchet ensures that the film material maintains the required tension through mechanical locking, and works with the fixing seat 241 and the snap-fit ​​242 at the end of the insulation film 23 to fix the protective film. When it needs to be retracted, pressing the release button will trigger the release of the elastic potential energy of the torsion spring, so that the insulation film 23 can be smoothly and automatically rolled back and stored.

[0047] By replacing traditional manual winding operations with the coordinated use of torsion springs and limiting components, construction efficiency is ensured while avoiding potential damage to the membrane material caused by manual operation. Furthermore, the precise control of the limiting components ensures a smooth and orderly rewinding process, preventing tangling caused by rapid rebound, and also secures the protective film to prevent damage to the protective film or the limiting components due to self-rebound. This significantly improves the efficiency of the insulation film winding and unwinding operations and greatly extends the service life of the equipment.

[0048] like Figures 1-2 As shown, in some embodiments, the telescopic connection assembly 13 includes a first link 131 and a second link 132. The first link 131 and the second link 132 are arranged crosswise and hinged by a hinge axis. The two ends of the first link 131 and the second link 132 are slidably connected to the first frame 11 and the second frame 12 connected thereto, respectively. Alternatively, the two ends of the first link 131 and the second link 132 are slidably connected to the second frame 12 and the second frame 12 connected thereto, respectively.

[0049] Specifically, the first frame 11 and the second frame 12 are provided with slide rods along the height direction, and both ends of the first connecting rod 131 and the second connecting rod 132 are provided with sleeves, which are slidably connected. In addition, the sleeves are provided with locking elements, which can lock the position of the sleeves on the slide rods.

[0050] The design of the sliding rod and sleeve allows the cross linkage to slide smoothly along the frame, achieving stable telescopic movement. Combined with an adjustable locking mechanism, this ensures the frame remains stable after reaching the desired length. The sleeve and sliding rod work together to ensure smooth movement while preventing loosening of the connection points. The locking mechanism provides a secure positioning function, allowing the frame to withstand external pressure without displacement after deployment. This makes telescopic adjustment more precise and controllable, while maintaining the overall rigidity of the frame structure. The entire telescopic connection assembly 13, through sliding and locking operations, achieves a perfect combination of rapid adjustment and stable support for the construction device, significantly improving ease of use and safety.

[0051] like Figure 2 As shown, in some embodiments, a movable component 3 is fixedly provided at the bottom of both the first frame 11 and the second frame 12.

[0052] Specifically, the movable component 3 includes a connecting seat, a universal wheel, and a limiting member. The connecting seat is fixed to the bottom of the first frame 11 and the second frame 12, the universal wheel is fixed to the connecting seat, and the limiting member is fixed to the connecting seat. The limiting member is used to restrict the rotation of the universal wheel.

[0053] The movable component 3, equipped with casters, allows the frame structure to move flexibly across the construction site, easily adapting to the needs of different work areas. Furthermore, operable limiting devices ensure the equipment remains stable after being positioned, preventing accidental displacement during construction. The fixed design of the connecting base guarantees a reliable connection between the movable component 3 and the main frame, maintaining good stability of the overall structure during movement. The casters can adapt to the multi-directional movement requirements of complex construction sites, significantly reducing the labor intensity of manual handling. The limiting devices effectively inhibit wheel rolling, providing a solid support foundation for the construction process.

[0054] The mobile component 3, by switching between mobile and fixed modes, not only meets the mobility requirements of maintenance equipment that is frequently moved, but also ensures the stability requirements during the construction phase, significantly improving work efficiency and safety.

[0055] like Figures 1-2 As shown, in some embodiments, the first frame 11 and the second frame 12 both include a crossbeam and two support columns. The two support columns are respectively fixedly installed at both ends of the crossbeam. The crossbeam and the two support columns are arranged in a gate shape. The insulation mechanism 2 includes multiple components, and the multiple insulation mechanisms 2 are respectively installed on the crossbeam and the two support columns.

[0056] A stable support system is constructed through the combination of portal-shaped beams and supporting columns, providing a reliable installation foundation for the insulation mechanism 2. The rational distribution of multiple insulation mechanisms 2 on the frame ensures uniform coverage of the protective film. The symmetrical design of the portal structure gives the frame excellent load-bearing performance, effectively resisting external loads. The synergistic effect of the beams and supporting columns ensures the stability of the overall structure and provides ample support space for the unfolding of the insulation film 23.

[0057] like Figures 1-3 As shown, in some embodiments, a roller blind mechanism 4 is also included. The roller blind mechanism 4 includes a roller blind box 42, a roller blind 41, and a rotating rod. The roller blind box 42 is disposed at the bottom of the crossbeam of the first frame 11. The rotating rod is fixed inside the roller blind box 42. The roller blind 41 is telescopically disposed inside the roller blind box 42 and wound around the rotating rod. The extended end of the roller blind 41 is provided with a fixing member for fixing to the support columns at both ends of the crossbeam.

[0058] The retractable roller shutter structure built into the roller shutter box 42 allows for flexible unfolding or retraction as needed, forming a complete enclosure barrier. The winding mechanism of the roller shutter 41 on the rotating rod ensures smooth unfolding and retraction, guaranteeing a seamless operation. The fasteners securely fix the unfolded roller shutter 41 to the support column, creating a stable, enclosed state. The roller shutter 41, in conjunction with the insulation film 23, effectively blocks the intrusion of lateral cold air, creating a more sealed environment for concrete curing. The roller shutter mechanism 4 enables the opening and closing of the frame opening, significantly improving the overall performance and ease of construction of the insulation system.

[0059] In addition, the roller blind 41 achieves extension and retraction in the same way as the protective film, and the specific settings are the same. Therefore, the specific structure of the roller blind 41 for achieving extension and retraction will not be described in detail here.

[0060] like Figures 1-2As shown, in some embodiments, a heating mechanism is also included. The heating mechanism includes an electric heating layer, a temperature controller, and a power supply module. The electric heating layer is laid on the inner side of the insulation film 23. The electric heating layer and the insulation film 23 are wound together on the rotating shaft 22. The temperature controller is electrically connected to the electric heating layer and is used to adjust the heating temperature. The power supply module provides power to the electric heating layer and the temperature controller.

[0061] By integrating the electric heating layer with the insulation film 23, the heating element can be deployed synchronously with the insulation cover, ensuring that heat is evenly transferred to the concrete surface. The intelligent adjustment function of the temperature controller dynamically adjusts the heating power according to environmental changes, keeping the temperature within the optimal curing temperature range. The stable output of the power supply module provides continuous energy to the heating mechanism, ensuring long-term operational reliability.

[0062] This heating mechanism effectively solves the problem of uneven temperature control in traditional curing methods, and can prevent stress cracks in concrete caused by temperature fluctuations. Furthermore, the synergistic work of the heating layer and the insulation film 23 not only improves the efficiency of heat energy utilization, but also simplifies the construction operation process.

[0063] In some embodiments, a temperature and humidity control system is also included, which includes a temperature and humidity sensor and a control unit. The temperature and humidity sensor is disposed inside the insulation film 23 and is used to monitor the temperature and humidity of the concrete surface in real time. The control unit is electrically connected to the temperature and humidity sensor and is used to receive and process the monitoring data.

[0064] Temperature and humidity sensors installed inside the insulation film 23 collect real-time environmental data of the concrete surface, providing accurate monitoring data for the curing process. The collected data is then analyzed and processed in real time by the control unit to dynamically adjust the heating and moisturizing systems.

[0065] By employing a closed-loop feedback control principle, the humidity control system ensures that the concrete is always in an optimal temperature and humidity environment, guaranteeing full cement hydration. Real-time monitoring by the temperature and humidity control system can promptly detect environmental anomalies and automatically initiate corresponding adjustment measures, effectively preventing quality defects caused by uncontrolled temperature and humidity and avoiding the uncertainties of traditional curing methods that rely on manual experience.

[0066] Specifically, the temperature and humidity control system also includes an actuator, which is electrically connected to the control unit. The actuator adjusts the heating mechanism based on the temperature analysis results obtained from the control unit, thereby improving the temperature.

[0067] In addition, a humidification mechanism is provided in this embodiment, which is fixed on the first frame 11. The humidification mechanism is a humidifier, and its specific structure will not be described in detail here. The actuator is electrically connected to the humidification mechanism and can adjust the humidification mechanism according to the humidity analysis results obtained by the control unit, thereby improving the humidity.

[0068] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
