Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically to a cooling water pipe connection structure for large-volume concrete pouring. Background Technology

[0002] Massive concrete refers to concrete structures with a minimum cross-sectional dimension greater than 1m. The heat of cement hydration is released in a concentrated manner, and the internal temperature rises rapidly. Its size is so large that appropriate technical measures must be taken to properly handle the temperature difference, reasonably resolve temperature stress, and control crack propagation. Cooling the internal temperature of concrete is generally achieved by using a cooling system.

[0003] The utility model patent with authorization announcement number CN 219219021 U discloses a large-volume concrete cooling circulation device, which includes: a foundation pit, a concrete pouring surface at the bottom of the foundation pit, cooling water pipes arranged in a serpentine pattern on the concrete pouring surface, a booster water pump installed on the side wall of the foundation pit, an inlet pipe installed on the booster water pump, a first water tank installed at the input end of the inlet pipe on one side of the top of the foundation pit, a dewatering well installed on one side of the first water tank via a pipe, a cooling unit and a second water tank installed sequentially on the other side of the first water tank via pipes, the output end of the inlet pipe connected to the input end of the cooling water pipe, a water flow regulating mechanism installed between the inlet pipe and the cooling water pipe, and an outlet pipe installed at the output end of the cooling water pipe, the output end of the outlet pipe connected to the second water tank. This device regulates the cooling water flow rate and volume through the water flow regulating mechanism to ensure the internal cooling rate of the concrete and prevent temperature shrinkage cracks in the concrete; after the cooling water is heated through circulation, it is cooled by the cooling unit and re-enters the cooling water circulation, saving costs and avoiding waste.

[0004] In the aforementioned publicly available results, cooling water pipes are directly installed vertically for cooling and temperature reduction. However, the lack of a positioning block for connecting the main pipeline to combine and lock the threaded rod and cooling water pipes makes it impossible to install them separately, resulting in poor adaptability and interchangeability. This makes it difficult to directly combine, install, replace, and maintain the pipes, and improvements are needed. Utility Model Content

[0011] Preferably, one side surface of the positioning block is provided with an arc-shaped surface, which is in contact with the outer surface of the main pipe.

[0012] Preferably, a sealing gasket is fixedly connected to the inner side of the arc-shaped surface, and the sealing gasket is pressed and connected to the outer surface of the main pipe.

[0013] Preferably, the sealing gasket is located on one side of the mating hole and is fitted to one end surface of the first connecting hole.

[0023] This utility model provides a technical solution: a cooling water pipe connection structure for large-volume concrete pouring. (See also...) Figure 1 , Figure 2 and Figure 3The system includes a main pipe 1, which can be connected to a circulating pump to supply circulating water for cooling and protection of the concrete blocks, ensuring project quality. A support plate 11 is fixedly welded to the lower surface of the main pipe 1. A first connecting hole 12 is provided on one side of the outer surface of the main pipe 1. Positioning blocks 13 are connected to both sides of the outer surface of the main pipe 1, allowing for positioning from both sides and interchangeable installation, providing high adaptability and avoiding misalignment and interference that could affect stability. Connecting rods 14 are fixedly connected to the upper and lower surfaces of the positioning blocks 13. A second connecting hole 15 is provided at one end of the connecting rod 14, allowing a locking threaded rod 16 to be connected to the second connecting hole 15. Locking nuts 17 can then be installed from both ends for locking and securing, thereby pressing the connecting rod 14 and the positioning blocks 13 on both sides. The clamping and positioning mechanism is located on both sides of the outer surface of the main pipe 1. It can be installed and fixed separately, which is conducive to combined use. Both ends of the locking threaded rod 16 are threaded with locking nuts 17. One side of the locking nut 17 is tightly connected to one end surface of the connecting rod 14. One side of the outer surface of the positioning block 13 is provided with a mounting threaded hole 2. The cooling water pipe 21 is threadedly installed inside the mounting threaded hole 2. The mounting threaded hole 2 is provided with a mating hole 22. The mating hole 22 is mated to one side of the first connecting hole 12. The cooling water pipe 21 is threaded into the mounting threaded hole 2 and can be connected to one end of the mating hole 22. In this way, combined with the first connecting hole 12 connected to the inside of the main pipe 1, the cooling water pipe 21 can be connected at multiple branch positions, thereby increasing the cooling range, which is conducive to combined use and has high adaptability.

[0024] Please see Figure 1 and Figure 2 There are two positioning blocks 13, which are symmetrically connected to the two sides of the main pipe 1. The connecting rods 14 are respectively connected to the upper and lower sides of the positioning blocks 13 and are symmetrically distributed on both sides of the main pipe 1. The locking threaded rods 16 are respectively connected to the upper and lower sides of the main pipe 1 and are located in the gap of the support plate 11. By symmetrically connecting the positioning blocks and connecting rods on both sides of the main pipe, combined with the locking threaded rods, the positioning blocks can be installed separately, which is convenient for interchangeability and does not restrict the installation angle and direction, making maintenance and use convenient.

[0025] Please see Figure 2 , Figure 4 and Figure 5One side surface of the positioning block 13 is provided with an arc-shaped surface 23, which is attached to the outer surface of the main pipe 1. A sealing gasket 24 is fixedly connected to the inner side of the arc-shaped surface 23. The sealing gasket 24 is pressed and connected to the outer surface of the main pipe 1.

By connecting the sealing gasket to the arc-shaped surface of the positioning block, it can fit the arc-shaped surface of the main pipe for positioning, ensuring the sealing performance of the separate installation, improving the stability of the cooling water flow, and facilitating the combined installation for cooling protection. When the positioning block 13 is attached to the surface of the main pipe 1 for positioning, the arc-shaped surface 23 can fit the arc-shaped surface of the main pipe 1 to ensure the contact area, thereby pressing the sealing gasket 24 for positioning, ensuring the sealing performance, and facilitating installation and use.
