Description

Technical Field

[0001] This utility model belongs to the field of concrete curing technology, and in particular relates to a concrete curing device for civil construction. Background Technology

[0002] Civil engineering construction, also known as civil engineering construction, is a comprehensive construction activity encompassing the entire process of building structures such as houses, roads, bridges, tunnels, and water conservancy projects. Its core function is to transform design drawings into actual engineering structures. After concrete pouring in civil engineering construction, the concrete needs to be cured to prevent surface cracking, insufficient strength, and decreased impermeability and frost resistance. This ensures the concrete receives sufficient moisture, suitable temperature, and a favorable environment after pouring, thereby achieving the designed strength, durability, and volume stability. Concrete curing is a crucial link in the "three parts pouring, seven parts curing" principle. Scientific curing methods must be selected based on the component type and environmental conditions, and the timing, duration, temperature, and humidity of curing must be strictly controlled to ensure the final performance of the concrete meets design requirements.

[0003] In winter, felt is often used for concrete curing. The felt is placed over the poured concrete to provide both insulation and moisture retention, effectively meeting the temperature and humidity requirements during the concrete hardening process. Currently, felt is mostly laid manually by rolling or using support frames. The felt is generally in roll form, and rolling involves manually pushing it open. This method is slow and labor-intensive. While support frames are slightly faster than manual rolling, they also have drawbacks. The felt material is relatively soft, and under the pressure of the support frame, the roll can deform, making it difficult to unfold. Therefore, we propose a concrete curing device for civil construction. Utility Model Content

[0025] Example 1: This example provides a concrete curing device for civil construction, including: a first support rod 1 and a felt 2. Two first support frames 3 are fixedly installed below the first support rod 1, and the two first support frames 3 are symmetrical. The inner walls of the two first support frames 3 are fixedly connected to support shafts 4, and the outer surfaces of the support shafts 4 are rotatably connected to rollers 5. A second support frame 6 is fixedly connected to the lower part of the first support rod 1, and the second support frame 6 is located between the two first support frames 3. A through hole 7 is opened on the inner side of the second support frame 6, and the center of the through hole 7 is higher than the support shaft 4. The inner wall of the through hole 7 is in contact with the support cylinder 8. A positioning plate 9 is fixedly connected to one end of the support cylinder 8. A positioning mechanism 10 is provided on the outside of the second support frame 6. The felt 2 is fixedly installed on the outside of the support cylinder 8.

[0026] The roller 5 provides support at the front and rear of the felt 2, while the second support frame 6 and the support cylinder 8 provide support for the felt 2. After the felt 2 is placed inside the second support frame 6, the height of the through hole 7 is higher than that of the support shaft 4, so that the felt 2 is suspended in the air, which makes it easier for the felt 2 to be unrolled. The inside of the support cylinder 8 is hollow, which can effectively reduce the weight of the support cylinder 8.

[0027] Example 2: This example provides a concrete curing device for civil construction. In addition to the technical solution of the above example, it also has the following technical features: a second support rod 11 is fixedly connected to one side of the positioning plate 9, a handle 12 is sleeved on the outside of the second support rod 11, a positioning block 13 is fixedly connected to the end of the second support rod 11 away from the support cylinder 8, and one side of the positioning block 13 is in contact with the inner wall of the handle 12.

[0028] The handle 12 is used to apply force to the support cylinder 8, causing the support cylinder 8 to move. After the felt 2 on the support cylinder 8 is used up, the support cylinder 8 can be pulled out from the through hole 7 through the handle 12. The second support rod 11 is used to adjust the angle of the handle 12, making it convenient for the user to pull the support cylinder 8.

In addition to the technical solutions of the above examples, it also has the following technical features: a handle 14 is fixedly connected to one end of the first support rod 1, and a handle sleeve 15 is sleeved on the outside of the handle 14. The handle sleeve 15 is made of rubber.

[0030] The handle 14 is used to control the direction of movement of the overall concrete curing device, and the handle 14 reduces the friction between the handle 14 and the hand, thus improving the comfort of use.

[0031] Example 4: This example provides a concrete curing device for civil construction. In addition to the technical solutions of the above examples, it also has the following technical features: the positioning mechanism 10 includes a slide 1001, one side of the slide 1001 is fixedly connected to one side of the second support frame 6, the inner wall of the slide 1001 is in contact with a clamping plate 1002, and one side of the clamping plate 1002 is in contact with the outer surface of the positioning plate 9.

[0032] The positioning mechanism 10 acts as a barrier outside the positioning disk 9, thereby maintaining the stability of the positioning disk 9 and the support cylinder 8. The slide block 1001 provides support for the clamping plate 1002, maintaining the stability of the clamping plate 1002. After the clamping plate 1002 moves downward, it wraps around the outside of the positioning disk 9, preventing the positioning disk 9 and the support cylinder 8 from moving.

In addition to the technical solutions of the above examples, it also has the following technical features: a pull rod 1003 is rotatably connected above the plate 1002, the outer surface of the pull rod 1003 is slidably connected to the inner wall of the slide block 1001, and a pull ring 1004 is fixedly connected to one end of the pull rod 1003 located outside the slide block 1001.

[0034] The pull ring 1004 facilitates the user's exertion of force, making it easy to move the pull rod 1003 and the clamping plate 1002.

[0035] Example 6: This example provides a concrete curing device for civil construction. In addition to the technical solutions of the above examples, it also has the following technical features: a spring 1005 is sleeved on the outside of the pull rod 1003. One end of the spring 1005 is in contact with the top of the clamping plate 1002, and the other end of the spring 1005 is in contact with the inner top wall of the slide block 1001.

[0036] When the pallet 1002 moves upward, the spring 1005 is compressed, and the spring 1005 provides elastic pushing force to the pallet 1002, pushing the pallet 1002 to contact the positioning disk 9 tightly, preventing the pallet 1002 from moving out of contact with the positioning disk 9.

[0037] Example 7: This example provides a concrete curing device for civil construction. In addition to the technical solutions of the above examples, it also has the following technical features: a sleeve 1006 is fixedly connected above the slide block 1001, and the sleeve 1006 is sleeved on the outside of the pull rod 1003. A slide 1007 is provided on the inner side of the sleeve 1006. The inner wall of the slide 1007 is in contact with the outer surface of the pull ring 1004. A positioning groove 1008 is provided on the inner side of the sleeve 1006, and the positioning groove 1008 is adapted to the pull ring 1004.

[0038] The slide 1007 inside the sleeve 1006 provides space for the pull ring 1004 to move, and the positioning groove 1008 provides support for the pull ring 1004 to maintain its stability. After the pull ring 1004 drives the pull rod 1003 and the clamping plate 1002 to move upward, the pull ring 1004 is rotated to align with the positioning groove 1008 and placed inside the positioning groove 1008. The positioning groove 1008 wraps around the pull ring 1004, thereby maintaining its stability and preventing it from moving.

[0039] Working principle: First, place the felt 2 inside the second support frame 6 and raise the felt 2. Then, pass the support cylinder 8 through the through hole 7 and into the roll inside the felt 2. Then, pass the support cylinder 8 into the through hole 7 at the other end of the second support frame 6. Then, pull the ring 1004 out of the positioning groove 1008 and rotate the ring 1004 to align it with the slide 1007. Release the ring 1004, and the spring 1005 pushes the claw to move downward. The claw wraps around the outside of the positioning plate 9 to maintain the stability of the support cylinder 8 and the positioning plate 9 and prevent the support cylinder 8 from moving. At the same time, the claw enters the slide 1007. Then, the entire concrete curing device can be moved by pushing the handle 14. While the concrete curing device is moving, the pressure from the rear roller 5 causes the felt 2 to roll and lay the felt 2 on the surface of the concrete.
