Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, and in particular to a membrane structure suitable for curing ultra-high performance concrete. Background Technology

[0002] With the widespread application of ultra-high performance concrete (UHPC) in bridges, high-rise buildings, and special projects, its curing process has become increasingly critical to the final strength, durability, and crack resistance of the material. Due to its extremely low water-cement ratio and high content of active powder, UHPC requires precise control of moisture replenishment and sealing during curing to avoid early plastic shrinkage cracks and later strength loss. Traditional curing methods often rely on manual mulching combined with timed watering. However, in large-area or complex curved surface construction scenarios, problems such as inadequate mulching adhesion and uneven watering can easily occur, leading to insufficient local humidity or water accumulation inside the membrane, thus causing UHPC performance degradation. Especially in high-temperature and high-wind environments, the efficiency and reliability of traditional curing methods cannot meet the demands of modern engineering for refined and automated construction.

[0003] Existing UHPC curing equipment suffers from several drawbacks. The curing liquid spraying system often uses fixed pipelines or manual spraying, which cannot be synchronized with the coating process, leading to uneven liquid film distribution or waste. The coating mechanism relies on manual installation, resulting in poor roll positioning accuracy and susceptibility to wrinkles, misalignment, or damage during coating, affecting the sealing effect. Traditional coating devices lack integrated mobile design, requiring frequent adjustments to equipment position during long-distance or curved surface construction, resulting in low efficiency and poor continuity. Furthermore, existing coating frame structures lack sufficient rigidity and are prone to deformation under long-term environmental factors (such as wind load and temperature differences), making it difficult to stably support the roll and coating tension. Therefore, we offer a coating structure suitable for ultra-high performance concrete curing. Utility Model Content

[0027] Example 1

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a membrane structure suitable for curing ultra-high performance concrete, including: a moving mechanism 1, the moving mechanism 1 including a mounting frame 11, a reinforcing frame 12 provided at the bottom of the mounting frame 11, moving rollers 13 provided on both sides of one end of the reinforcing frame 12, an auxiliary roller 14 provided at the end of the reinforcing frame 12 away from the moving rollers 13, an extension frame 15 provided in the reinforcing frame 12 at the bottom of the mounting frame 11, a pusher 16 provided on the same end of the reinforcing frame 12 and the moving rollers 13, and a wetting mechanism 2 provided on the mounting frame 11;

[0029] The humidification mechanism 2 includes an installation box 21, a storage box 22 is provided in the installation box 21, a temporary storage chamber 23 is provided at the bottom of the storage box 22, a water pump 24 is provided at the bottom of the temporary storage chamber 23, and a spray pipe 25 is provided at one end of the water pump 24.

[0030] One end of the reinforcing frame 12 is welded to the bottom of the mounting frame 11. One side of the moving roller 13 is installed on one side of one end of the reinforcing frame 12. The auxiliary roller 14 is connected to the bottom of the reinforcing frame 12. One side of the extension frame 15 is welded to the bottom of the mounting frame 11. The flat pusher 16 is installed at one end of the reinforcing frame 12. The outer surface of the storage box 22 is nested in the mounting box 21. The temporary storage cavity 23 is connected to the bottom of the storage box 22. One end of the water pump 24 is connected to one end of the temporary storage cavity 23. One end of the spray pipe 25 is connected to the water pump 24.

[0031] In this embodiment, when using this film covering device to cure and cover concrete, the worker can place the moving mechanism 1 at the location where film covering is needed. Then, the worker can push the mounting frame 11 to move the moving rollers 13 and auxiliary rollers 14 at both ends of the bottom reinforcing frame 12, thereby moving the entire moving mechanism 1. During the movement, the worker can control the switch of the water pump 24 to draw the curing liquid in the storage tank 22 into the water pump 24 through the temporary storage chamber 23 and then spray it out through the spray pipe 25.

[0032] Example 2

[0033] like Figure 1-4 As shown, the bottom of the mounting frame 11 is located in the reinforcement frame 12 and a film covering mechanism 3 is provided. The film covering mechanism 3 includes a film covering frame 31, a fixed film covering cylinder 32 is provided at one end of the film covering frame 31, and an adjusting roller cylinder 33 is provided in the film covering frame 31.

[0034] One end of the film-coating frame 31 is welded to the bottom of the mounting frame 11. The two ends of the fixed film-coating cylinder 32 are connected to the film-coating frame 31. The two ends of the adjusting roller cylinder 33 are connected to the film-coating frame 31 for lifting and lowering adjustment.

[0035] In this embodiment, to further enhance its practicality in actual use, a corresponding film covering mechanism 3 is provided in the reinforcing frame 12 at the bottom of the mounting frame 11. Workers can weld one end of the film covering frame 31 to the bottom of the mounting frame 11 and place the film covering roll on the outer surface of the fixed film covering roll 32. In this way, the moving mechanism 1 will allow the film on the outer surface of the fixed film covering roll 32 to cover the ground during the movement, thereby further enhancing its practicality in actual use.

[0036] Working principle:

[0037] like Figure 1-4 As shown, when using this membrane covering device to perform curing and membrane covering operations on concrete, the worker first places the entire mobile mechanism 1 in the designated area where curing and membrane covering are required. Then, the worker pushes the mounting frame 11, causing the reinforcing frame 12 at its base to move accordingly. At both ends of the reinforcing frame 12, there are respectively moving rollers 13 and auxiliary rollers 14. Through the coordinated movement of these rollers, the entire mobile mechanism 1 moves smoothly, ensuring that the device can operate along the predetermined path.

[0038] During the relocation process, workers can turn on the water pump 24 as needed to start it up. The water pump 24 draws the curing liquid stored in the storage tank 22 into the pump body through the temporary storage chamber 23, and then sprays the curing liquid evenly onto the concrete surface through the connected spray pipe 25. This process ensures that the concrete receives a continuous and uniform supply of moisture during the initial or final setting stages, thereby effectively preventing cracking and improving its strength and durability.

[0039] To further enhance the practicality and versatility of the device in real-world applications, a specialized film-coating mechanism 3 is integrated into the reinforcing frame 12 at the bottom of the mounting frame 11. Workers can securely weld one end of the film-coating frame 31 to the bottom of the mounting frame 11, ensuring it does not loosen or shift during operation. Simultaneously, the roll for curing the film is mounted on the outer surface of the fixed film-coating roll 32. This structural design allows the film-coating material to unfold naturally during movement.

[0040] As the moving mechanism 1 moves slowly along the concrete surface, the covering material installed on the fixed covering cylinder 32 is simultaneously laid, covering the concrete surface that has been sprayed with curing liquid. This continuous operation process greatly improves the efficiency of the curing operation, ensuring that spraying and covering are completed simultaneously, and effectively avoiding the problem of uneven curing caused by time delays.

[0041] This film-covering device has a compact structure and is easy to operate. It can flexibly adjust the direction and speed according to the actual conditions of the construction area, and can realize integrated spraying and film-covering operations, significantly reducing manual operation steps and improving construction efficiency. The design of the fixed film-covering cylinder 32 also supports the installation of film-covering rolls of different sizes and materials, enhancing the device's adaptability to different construction needs.

[0042] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0043] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
