TECHNICAL FIELD
[0001] The utility model relates to the technical field of precast beam maintenance, especially to a kind of maintenance device for prefabricated T beam summer and winter construction. BACKGROUND
[0002] In bridge engineering, the upper structure is usually pre-processed before the lower structure construction is completed, such as prefabricated T beam and prefabricated box beam. After the lower structure construction is completed, the upper structure can be assembled on the lower structure, thereby greatly shortening the construction period of the entire project. However, after the prefabricated T beam is poured, it needs to be cured for about 28 days to ensure that the concrete reaches the required strength of the design.
[0003] Traditionally, the curing of prefabricated T beam and box beam after pouring is achieved by covering insulation materials such as film or geotextile, supplemented by manual watering. This method has several obvious disadvantages:
[0004] Low efficiency: manual watering is not only time-consuming and labor-intensive, but also difficult to ensure that each prefabricated component receives uniform and sufficient water supply in large-scale construction sites, especially when there are many prefabricated components, some sides may be missed or insufficiently watered, which can cause the concrete surface to dry too quickly, resulting in cracks and affecting the overall quality of the structure.
[0005] Temperature control difficulty: especially in low temperature conditions in winter, the traditional covering method is difficult to effectively maintain the temperature of the prefabricated beam after demolding. The hydration heat inside the concrete will evaporate quickly, causing the surface temperature to fluctuate greatly and unable to maintain within a stable range. This temperature instability can affect the solidification process of the concrete, making it difficult to reach the required tensile strength and elastic modulus within the specified time.
[0006] Quality problem: if the concrete cannot harden normally in a suitable environment, it may lead to slow or even stop growth of late strength, thereby seriously affecting the construction quality and progress. SUMMARY
[0007] To solve the technical problems of low efficiency and temperature control difficulty of existing curing methods, the utility model provides a curing device for prefabricated T beam summer and winter construction, which improves curing efficiency and effectively controls temperature and humidity.
[0008] The technical solution adopted by the utility model to solve its technical problems is:
[0009] The cam is connected to the support frame of the lifting post by the spring, and the support frame is connected to the support frame by the spring.
[0010] Furthermore, the length directions of the water supply pipe and the constant temperature lamp are consistent with the arrangement direction of the multiple portal frames.
[0011] Furthermore, at least two water supply pipes and at least two constant temperature lamps are provided on the vertical pipe on one side of the gantry, and the water supply pipes and the constant temperature lamps are arranged at intervals in the vertical direction.
[0012] Furthermore, there are three water supply pipes and three thermostatic lamps, and the water supply pipes and the thermostatic lamps are arranged in a staggered manner.
[0013] Furthermore, the riser is a galvanized steel pipe.
[0014] Furthermore, a collection tank for recovering spray water is provided at the bottom of the gantry.
[0015] Furthermore, the lower ends of the two vertical pipes of each gantry are provided with universal wheels.
[0016] The beneficial effects of the utility model are:
[0017] 1. The design creates a movable and structurally stable curing environment through the combination of multiple supporting scaffolds and multiple portal frames. Connecting rods and cross-links ensure the stability of the overall frame, while the design of slides and pins allows the entire device to be freely extended and retracted according to actual needs, enhancing flexibility. This not only facilitates the transfer of equipment between different sites, but also facilitates the adjustment of coverage according to the actual size of the prefabricated T-beams. In addition, the provision of water supply pipes and constant temperature lamps ensures that the concrete can receive sufficient water supply and appropriate temperature control during the curing process. This type of automated spraying and heat preservation curing solves the problem of low efficiency of traditional manual curing. When the temperature is low in winter, the constant temperature lamps ensure that the prefabricated T-beams are cured at an appropriate temperature, which helps to improve the quality of the final product.
[0018] 2. Direction consistency of water supply pipes and constant temperature lamps: The water supply pipes and constant temperature lamps are arranged along the arrangement direction of the portal frames, which helps to evenly distribute water resources and heat energy, thereby creating a balanced humidity and temperature environment throughout the entire curing area, avoiding local over-wetting or over-drying.
[0019] 3. Vertical and spaced arrangement of multiple water supply pipes and constant temperature lamps: At least two water supply pipes and constant temperature lamps are provided and are spaced along the vertical direction, which can further optimize the water mist coverage range and heat transfer efficiency, ensuring that each precast T beam can receive sufficient moisture and suitable temperature.
[0020] 4. The design of three water supply pipes and constant temperature lamps staggered arrangement not only improves the uniformity of water mist and heat distribution throughout the entire curing area, ensuring that the precast T beam is uniformly hardened under ideal humidity and temperature conditions, avoiding quality problems caused by local over-wetting or over-drying; at the same time, this layout effectively reduces the possibility of direct impact of the spray flow on the constant temperature lamp, protecting the heating element and improving the reliability and efficiency of the system. In addition, staggered distribution helps to achieve balance of humidity and temperature throughout the entire curing area, optimizing resource utilization, saving water resources and improving energy efficiency.
[0021] 5. Using galvanized steel pipe as standpipe material: Galvanized steel pipe has good corrosion resistance and mechanical strength, can withstand long-term use in outdoor environment, and reduces maintenance cost and prolongs equipment service life.
[0022] 6. Collecting tank for recycling spray water: The bottom is provided with a collecting tank to effectively recycle the sprayed water, which not only saves water resources, but also prevents safety hazards caused by accumulated water on site, and also maintains the cleanliness of the construction site.
[0023] 7. Universal wheel design: The lower end of each standpipe is equipped with universal wheels, making the entire curing device easy to move, allowing easy adjustment of position according to actual needs, enhancing the flexibility and adaptability of the device, which is very helpful for improving construction efficiency.

[0031] Reference Figs. 1-2 The present application provides a kind of for prefabricated T beam summer and winter construction maintenance device.
[0032] In some embodiments, a maintenance device for prefabricated T-beams for summer and winter construction includes multiple support scaffolds 6 and multiple portal frames, wherein the multiple portal frames are arranged horizontally at intervals, and each portal frame includes two vertically arranged risers 1. A connecting rod 2 is provided on the upper part of the first portal frame and the last portal frame along the arrangement direction of the portal frames. The upper ends of the two risers 1 of the portal frames are connected and fixed by the connecting rod 2. The risers 1 of two adjacent portal frames on the same side are connected by two cross-arranged connecting rods 3. The outer side of each riser 1 is provided with a vertical slide groove. 4. The end of the connecting rod 3 is movably connected with a pin 5, which is movably mounted in the slide groove 4 and can slide back and forth along the slide groove 4. The single supporting scaffold 6 includes a cross bar 61, an arc-shaped supporting rod 62 and two vertical rods 63. The two vertical rods 63 are vertically arranged and connected by the cross bar 61. The upper ends of the two vertical rods 63 are connected by the arc-shaped supporting rod 62. The vertical rods 63 of the single supporting scaffold 6 are sleeved in the riser 1 of the single gantry frame. The riser 1 of the gantry frame is provided with a water supply pipe 7 and a constant temperature lamp 9. The water supply pipe 7 is provided with multiple sprinkler heads 8 in its own length direction.

To avoid rain intrusion, a tarpaulin can be laid outside the supporting scaffolds 6 and the portal frames and fixed with screws. Windows can also be opened on the tarpaulin to ensure that the entire device has a certain ventilation effect.
[0034] As for how to set the water supply pipe 7 and the constant temperature lamp 9 on the gantry, the length direction of the water supply pipe 7 and the constant temperature lamp 9 can be made consistent with the arrangement direction of multiple gantry frames.
