Description

Technical Field

[0001] This utility model relates to the technical field of circulating water steel pipe support structure for large-volume concrete pouring, specifically a circulating water steel pipe support structure for large-volume concrete pouring. Background Technology

[0002] Currently, my country's engineering construction is developing rapidly, with high-rise and super high-rise buildings increasing in number, and the application of large-volume concrete becoming more and more widespread. During the construction of large-volume concrete, a lot of heat is generated due to the heat of cement hydration. The heat on the concrete surface dissipates quickly, while the heat inside is not easily dissipated, resulting in a large temperature difference between the inside and the surface. When the temperature difference exceeds a certain critical value, temperature stress will be generated. When this temperature tensile stress is greater than the tensile strength of the concrete, cracks will appear in the concrete structure, thus affecting the durability of the project.

[0003] In the existing technology, such as the authorized announcement number CN203547144U, this utility model relates to a circulating pipe network structure for continuous one-time pouring of ultra-large volume concrete. Its innovation lies in: mainly including a circulating water steel pipe network and pre-set supports. The pre-set supports include several horizontal support steel pipes and vertical support steel pipes. The horizontal support steel pipes are connected by several vertical support steel pipes to form a three-dimensional frame structure, which is then placed in the sandwich layer between two brick walls of the ultra-large volume concrete to be poured. The circulating water pipe network includes several "S"-shaped planar deflection circulating water pipes vertically set on the pre-set supports, as well as a circulating water inlet main pipe and a circulating water outlet main pipe that respectively connect the inlet and outlet of each planar deflection circulating water pipe. The circulating water pipe network is used to send low-temperature water into each area of ​​the concrete center. After absorbing heat, it is discharged and circulated for exchange, making it difficult for the high-temperature zone of hydration heat inside the concrete to concentrate, reducing the impact on the constraints around the concrete. It can eliminate the need for temperature control structural reinforcement, cushion sliding layer and external constraint mitigation measures, speeding up the construction progress and reducing the construction cost.

[0004] In the aforementioned patent, an S-shaped pipe network structure is used to circulate cooling water and dissipate heat from the inside of the concrete. However, during construction, the S-shaped pipe network is an integral structure, which makes it difficult to add or reduce its use when used on a large scale. It is inconvenient to assemble and cannot be adjusted according to the volume of the concrete being constructed, making it inflexible in use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a circulating water steel pipe support structure for large-volume concrete pouring, which solves the problem of inflexible installation of water pipe networks during construction and the inability to adjust the structure according to the size of the concrete.

[0023] The inner end surface of the first locking sleeve 7 of the end face of the adding tube 2 is connected to the outer surface of the tube 1 by a thread, and the end face of the adding tube 2 and the end face of the tube 1 are pressed and fixed against each other; it is convenient to twist the first locking sleeve 7 for installation, and it can be fixed by threading on the adding tube 2. When the adding tube 2 is installed in a docking manner, it is also locked and fixed.

[0024] The end face of the adding tube 2 is provided with a first annular protrusion 70, and the inner side of the first locking sleeve 7 is provided with an annular groove. The outer surface of the first annular protrusion 70 is engaged with the inner surface of the annular groove of the first locking sleeve 7. When the first locking sleeve 7 is twisted outside the adding tube 2, it can be positioned and twisted at the first annular protrusion 70, which can drive the adding tube 2 to be connected, installed and locked.

[0025] The diameter of tube 1 and adding tube 2 is six centimeters. Both tube 1 and adding tube 2 are made of stainless steel. Rubber gaskets 71 are clamped and fixed to the inner surface of adding tube 2 and tube 1. After installation, the mating surfaces can be clamped and locked with rubber gaskets 71 to improve sealing.

[0026] The inner surface of the second locking sleeve 8 is provided with an annular groove, and the outer end surface of the second conduit 6 is provided with a second annular protrusion 80. The outer surface of the second annular protrusion 80 is engaged with the inner surface of the annular groove of the second locking sleeve 8.

Furthermore, the diameter of the ring frame tube rack 3 and the water guide pipe 4 is one centimeter, and the ring frame tube rack 3 and the water guide pipe 4 are made of stainless steel; they will not rust. Their small diameter results in a slow speed during backflow, and the large flow rate of cooling water introduced from the upper end can form the pressure for introduction, which can fill all the ring frame tube rack 3 and the water guide pipe 4, resulting in uniform and comprehensive cooling.

[0028] The working principle of this device is as follows: An adding pipe 2 is fixedly installed at the outer end of the pipe cylinder 1. Both the lower outer surfaces of the pipe cylinder 1 and the adding pipe 2 are provided with ring frame pipe supports 3. A water guide pipe 4 is provided on the inner side of the ring frame pipe support 3. A first guide pipe 5 is provided on the surface of the lower ring frame pipe support 3 of the pipe cylinder 1.

The cooling is guided through the ring frame tube frame 3 and the water guide pipe 4, and the circulation is discharged through the first guide pipe 5 and the second guide pipe 6 (the circulation part is existing technology and can be achieved by a circulation pump).

[0030] When in use, the diameter of the ring frame tube rack 3 and the water guide pipe 4 is one centimeter, and the ring frame tube rack 3 and the water guide pipe 4 are made of stainless steel; they will not rust. Their small diameter results in a slow flow rate during backflow, and the large flow rate of cooling water introduced from the top can create the pressure to fill all the ring frame tube rack 3 and the water guide pipe 4, resulting in uniform and comprehensive cooling.
