Description

Technical Field

[0001] The utility model relates to the technical field of mass concrete pouring, in particular to a mass concrete pouring cooling device. Background Art

[0002] Modern buildings often involve large-volume concrete construction, such as high-rise building foundations, large equipment foundations, water conservancy dams, etc. During the construction of large-volume concrete structures, the hydration reaction of cement will generate a large amount of hydration heat. Combined with the particularity of concrete materials, an uneven temperature field will be generated inside the concrete. The external cold concrete is constrained by the expansion and contraction of the internal hot concrete, thus generating temperature stress, which makes it easy for large-volume concrete to produce temperature cracks during the hardening process, reducing the bearing capacity, waterproof performance and durability of large-volume concrete, and affecting the safety and normal use of concrete structures.

[0003] At present, the most commonly used cooling control method is to bury cooling water pipes inside the large-volume concrete structure to be poured, and cool the concrete by manually pouring cooling water into the cooling water pipes or pumping cooling water into the cooling pipes. Since the newly poured concrete has not yet completely solidified, the interior is prone to deformation, and the pre-buried water pipes will vibrate when water is passed through them, and the water hammer effect is easily generated when the switch is opened and closed, causing the water pipes to shake in the concrete, resulting in gaps inside the concrete, affecting the quality of the concrete. At the same time, relying solely on cooling pipes to cool the concrete leads to low efficiency.

[0004] Therefore, it is necessary to provide a new large-volume concrete pouring cooling device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a large volume concrete pouring cooling device.

[0006] The large volume concrete pouring cooling device provided by the utility model comprises:

[0007] Cooling pipes, and

[0008] A rubber ball set on the tube wall;

[0009] Two symmetrically distributed U-shaped tubes in communication with the cooling tube are fixedly mounted on the cooling tube, and rolling rubber balls are embedded on the upper and lower tube walls of the cooling tube and the two U-shaped tubes.

[0010] Preferably, a central connecting pipe connected to pipelines on both sides of the U-shaped pipe is arranged between the two U-shaped pipes.

[0011] Preferably, rubber balls are embedded in the upper and lower pipes of the central connecting pipe to roll.

[0012] Preferably, spherical grooves are provided on the upper and lower tube walls of the cooling tube, the U-shaped tube and the central connecting tube, and the rubber balls are arranged in the spherical grooves.

[0013] Preferably, one third of the rubber ball extends out of the spherical groove, and the highest and lowest spherical surfaces of the rubber ball extend out of the upper and lower tube surfaces of the cooling tube respectively.

[0014] Preferably, spiral ridges are embedded on the outer pipes of the cooling tubes at the connection points of the U-shaped tubes.

[0015] Preferably, both ends of the cooling pipe are fixedly connected with a water inlet interface and a water outlet interface respectively.

[0016] Compared with the related art, the large volume concrete pouring cooling device provided by the utility model has the following beneficial effects:

[0017] The two U-shaped tubes arranged on the cooling tube of the utility model, on the one hand, the cooling tube cooperates with the U-shaped tube to increase the cooling area of ​​the cooling tube on the surrounding concrete, and on the other hand, the two U-shaped tubes also increase the contact area between the cooling tube and the concrete, so that the cooling tube is placed more stably during concrete pouring. At the same time, the rubber balls on the cooling tube and the U-shaped tube reduce the vibration and stress generated by the concrete structure when it is subjected to the action of external forces, and at the same time, the water hammer problem of the pipeline caused by the cooling tube and the U-shaped tube when conveying coolant can be reduced.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 3 The embodiment of the utility model provides a large volume concrete pouring cooling device, and the large volume concrete pouring cooling device includes: a cooling pipe 1 and a rubber ball 2.

[0025] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 The two ends of the cooling pipe 1 are respectively fixedly connected with a water inlet interface 5 and a drainage interface 6. Two U-shaped tubes 3 symmetrically distributed and connected to the cooling pipe 1 are fixedly installed on the cooling pipe 1, and the upper and lower tube walls of the cooling pipe 1 and the two U-shaped tubes 3 are embedded with rolling rubber balls 2. Specifically, spherical grooves 1a are opened on the upper and lower tube walls of the cooling pipe 1 and the U-shaped tube 3. The rubber ball 2 is arranged in the spherical groove 1a, and one third of the rubber ball 2 extends out of the spherical groove 1a, and the highest and lowest spherical surfaces of the rubber ball 2 extend out of the upper and lower tube surfaces of the cooling pipe 1 respectively.

[0026] It should be noted that: two symmetrically distributed U-shaped tubes 3 are arranged on the cooling tube 1. On the one hand, the cooling tube 1 cooperates with the U-shaped tube 3 to increase the cooling area of ​​the surrounding concrete by the cooling tube 1. On the other hand, the two U-shaped tubes 3 also increase the contact area between the cooling tube 1 and the concrete, so that the cooling tube 1 is placed more stably during concrete pouring.

[0027] At the same time, the rubber balls 2 on the cooling pipe 1 and the U-shaped pipe 3 reduce the vibration and stress of the concrete structure when it is subjected to external forces, and can also reduce the water hammer problem of the pipeline caused by the cooling pipe 1 and the U-shaped pipe 3 when conveying the coolant;

[0028] Among them, spiral ridges 11 are embedded on the outer pipes of the cooling pipe 1 located at the connection of the U-shaped pipe 3, and spiral ridges 11 are embedded on the pipe walls on both sides of the cooling pipe 1, so that the cooling pipe 1 also serves as a steel bar, which can be used to support the internal structure of the large volume concrete and also can pass cooling water to cool the interior of the large volume concrete, avoiding material waste.

[0029] In the embodiments of the present invention, please refer to Figure 1 A central connecting pipe 4 connected to the pipes on both sides of the U-shaped pipe 3 is arranged between the two U-shaped pipes 3, and rubber balls 2 are embedded in the upper and lower pipes of the central connecting pipe 4, and spherical grooves 1a are opened on the upper and lower pipe walls of the central connecting pipe 4, and the rubber balls 2 are arranged in the spherical grooves 1a opened in the central connecting pipe 4.

[0030] It should be noted that the additional central connecting pipe 4 further increases the contact area between the cooling pipe 1 and the concrete and the cooling area of ​​the U-shaped pipe 3 on the concrete.

[0031] The working principle of the large volume concrete pouring cooling device provided by the utility model is as follows:

[0032] Two symmetrically distributed U-shaped tubes 3 are arranged on the cooling pipe 1. On the one hand, the cooling pipe 1 cooperates with the U-shaped tube 3 to increase the cooling area of ​​the surrounding concrete by the cooling pipe 1. On the other hand, the two U-shaped tubes 3 also increase the contact area between the cooling pipe 1 and the concrete, so that the cooling pipe 1 is placed more stably during concrete pouring. At the same time, the rubber balls 2 on the cooling pipe 1 and the U-shaped tube 3 reduce the vibration and stress generated by the concrete structure when it is subjected to external forces, and can also reduce the water hammer problem of the pipeline caused by the cooling pipe 1 and the U-shaped tube 3 when conveying coolant.
