Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, and more specifically, to a combined covering device for concrete curing in environments with large temperature differences. Background Technology

[0002] Concrete curing involves artificially creating certain humidity and temperature conditions to allow freshly poured concrete to harden normally or accelerate its strength development. Concrete curing blankets, also known as engineering blankets or highway maintenance insulation blankets, are curing devices used in concrete construction. In concrete curing under large temperature differences, the laying efficiency, fixing stability, and splicing reliability of the covering device directly affect the curing quality and construction progress. Traditional covering devices are inefficient and labor-intensive. Operators need to bend over and drag the rolls of material, which is physically demanding. Furthermore, the rolls are prone to wrinkling during the laying process, resulting in poor adhesion and creating blind spots in the curing process. Under large temperature differences, the concrete in these blind spots is prone to cracking due to sudden temperature changes. In addition, the edges need to be manually pressed down with heavy objects or fixed with simple clips during the laying process, which is inefficient. Therefore, a combined covering device for curing concrete in environments with large temperature differences is proposed. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a combined covering device for concrete curing in environments with large temperature differences, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a combined covering device for concrete curing in environments with large temperature differences, comprising a push rod, with first support rods symmetrically fixedly connected to both ends of the push rod, and two support legs fixedly connected to the bottom end of the first support rods. The bottom sides of the support legs are rotatably connected to movable wheels, which can be used to move the support legs by pulling the push rod, facilitating the laying of the covering roll. A support slot is provided at the top connection of the support legs, allowing for easy placement and removal of the support shaft and the covering roll, thus facilitating use.

[0005] A support shaft is provided in the middle of the support slot, and a cover roll is sleeved in the middle of the support shaft. The cover roll is supported by the support shaft. Hook and loop fasteners are provided on the inner and outer sides of both ends of the cover roll. A second support rod is rotatably connected to the side of the top connection of the support leg. A pressure post is rotatably connected to one end of the second support rod. The hook and loop fasteners can be tightly fixed at the joint of two adjacent cover rolls by the cooperation of the hook and loop fasteners. The pressure post on one side of the second support rod can squeeze the hook and loop fasteners to improve the bonding strength. The second support rod has a support hole at one end, a positioning hole in the middle of one of the support legs, and a rod inserted into the middle of the other support leg. A limiting plate is fixedly connected to one end of the rod, a spring is sleeved in the middle of the rod, a connecting rod is fixedly connected to one end of the rod, and a positioning rod is fixedly connected to one end of the connecting rod. By pulling the connecting rod, the limiting plate is controlled to compress the spring, and by rotating the connecting rod around the rod axis, the position of the positioning rod can be adjusted. When not in use, the positioning rod can be inserted into the middle of the support hole on one side of the second support rod to fix the angle of the second support rod, making it convenient for movement and carrying.

[0006] Preferably, the opening of the support slot is located at the top, and the two ends of the support shaft are respectively located in the middle of the support slot, so that the support shaft can be placed and removed easily through the support slot.

[0007] Preferably, the limiting plate and the spring are both disposed inside the corresponding support leg, and the diameter of the positioning rod corresponds to the positioning hole and the support hole. The connecting rod can be limited by the rod, the limiting plate, and the spring, which facilitates the adjustment of the position of the positioning rod.

[0008] Preferably, the pressure column is disposed on the opposite side of the two second support rods, and the two pressure columns are disposed on both sides of the extended end of the cover roll. By pressing the edge of the cover roll with the pressure column, the bonding and fixing strength of two adjacent cover rolls can be improved.

[0009] Preferably, the hook and loop fasteners are compatible with each other. The loop fasteners are placed on the inner surface of the cover roll, and the hook and loop fasteners are placed on the outer surface of the cover roll. By attaching the hook and loop fasteners together, two adjacent cover rolls can be automatically combined and fixed, which is convenient for covering concrete surfaces.

[0010] The technical effects and advantages of this utility model are as follows: 1. This utility model firstly facilitates the support of the central support shaft of the cover roll by setting a support slot, which makes it easy to install the cover roll. The pressure column can directly squeeze the edge of the cover roll during the laying process. The combination of hook and loop fasteners can automatically adhere and fix the splicing edges during the laying process, which improves the fixing effect. Furthermore, the roll can be moved and laid by manually pulling the push rod, which improves work efficiency. 2. This utility model also controls the positioning rod to move out of the positioning hole by pulling the connecting rod, and then the rod drives the limiting plate to squeeze the spring. Rotating the connecting rod controls the positioning rod to correspond with the support hole and inserting the positioning rod into the support hole can fix the position of the pressure column when not in use, and can be moved for use when not in use, thus improving the use effect. In summary, through the interaction of the above-mentioned multiple functions, it is convenient to place and limit the cover roll material, facilitate manual pulling and laying, and directly squeeze the edges during the laying process. The combination of hook and loop fasteners and hook and loop fasteners provides multi-functional fixation, improving the fixing effect and thus increasing work efficiency.

[0019] A support shaft 9 is provided in the middle of the support slot 5. A cover roll 6 is sleeved in the middle of the support shaft 9. The cover roll 6 is supported by the support shaft 9. Hook and loop fasteners 7 and hook and loop fasteners 8 are provided on the inner and outer sides of both ends of the cover roll 6, respectively. A second support rod 10 is rotatably connected to the side of the top connection of the support leg 3. A pressure post 11 is rotatably connected to one end of the second support rod 10. The hook and loop fasteners 7 and hook and loop fasteners 8 can be used to tightly fix the bonding area of ​​two adjacent cover rolls 6. The bonding strength can be improved by pressing the hook and loop fasteners 8 and hook and loop fasteners 7 with the pressure post 11 on one side of the second support rod 10. The second support rod 10 has a support hole 12 at one end, a positioning hole 13 in the middle of one support leg 3, and a rod 14 inserted into the middle of the other support leg 3. A limiting plate 15 is fixedly connected to one end of the rod 14, a spring 16 is sleeved in the middle of the rod 14, a connecting rod 17 is fixedly connected to one end of the rod 14, and a positioning rod 18 is fixedly connected to one end of the connecting rod 17. By pulling the connecting rod 17, the limiting plate 15 is controlled to compress the spring 16, and by rotating the connecting rod 17 around the axis of the rod 14, the position of the positioning rod 18 can be adjusted. When not in use, the positioning rod 18 can be inserted into the middle of the support hole 12 on one side of the second support rod 10 to fix the angle of the second support rod 10, making it convenient to move and carry.

[0020] As attached Figure 1-5 As shown, the opening of the support slot 5 is located at the top, and the two ends of the support shaft 9 are respectively located in the middle of the support slot 5. The limiting plate 15 and the spring 16 are both set inside the corresponding support leg 3. The diameter of the positioning rod 18 corresponds to the positioning hole 13 and the support hole 12.
