Technical Field

[0001] This utility model relates to the field of concrete temperature control technology, specifically a temperature control structure for large-volume concrete. Background Technology

[0002] Cold water pipes are one of the main measures for temperature control in large-volume concrete, and their effectiveness has been verified in practice. To ensure that the cold water pipes within the concrete are not damaged by pressure, they are mostly rigid pipes made of steel or plastic. Furthermore, for ease of transportation, cold water pipes are usually cut into 5-10m sections and assembled on-site. This not only increases assembly time and material waste, but also increases costs and the risk of leakage due to the numerous joints. Therefore, a flexible, rollable, and freely divisible cold water carrier deserves further research.

[0003] In existing technologies, the common temperature control method involves embedding water pipes inside the large-volume concrete structure to be poured. Cooling water is supplied to these pipes to lower the temperature, and the flow of water carries heat away from the concrete structure, reducing the temperature difference between the inside and outside of the concrete and between layers. Traditional methods require connecting multiple sections of water pipes by welding. If the welding quality is substandard, leaks can easily occur at the pipe joints. Such leaks not only affect the cooling effect of the cooling system but may also affect the final performance of the concrete due to moisture seeping into it. Utility Model Content

[0004] The purpose of this invention is to provide a temperature control structure for large-volume concrete, which aims to solve the problem in the prior art where substandard welding leads to leakage at water pipe joints, affecting the cooling effect of the cooling system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a temperature control structure for large-volume concrete, comprising a cooling circulation component installed within the concrete; The cooling circulation components are a plurality of units arranged vertically and spaced apart within the concrete. Each cooling circulation component is connected to a feed pipe extending in the left-right direction, and a discharge pipe extending in the up-down direction is connected between two adjacent cooling circulation components. Valves are installed on the feed pipe and the discharge pipe. All the feed connection pipes are connected to the same main pipe extending in the vertical direction. The top of the main pipe is fixed with a feed port, and the bottom left side of the cooling circulation component at the bottom is fixed with a discharge port. The cooling circulation assembly includes a long pipe, a short pipe, a right-angle pipe, and connectors. The long pipe and the right-angle pipe, as well as the short pipe and the right-angle pipe, are connected by connectors.

[0006] Preferably, each of the cooling circulation components has two long pipes spaced apart front to back, two short pipes spaced apart left to right, and four right-angle pipes. The right-angle pipes are installed on the opposite side of the long and short pipes, and the long pipes, short pipes, and right-angle pipes are connected to form a circulation pipe structure that is connected end to end. In each layer of the cooling circulation assembly, the right side of the short pipe located on the right side is fixedly connected to the feed connection pipe, and the bottom left side of the short pipe located on the left side in the bottom layer of the cooling circulation assembly is fixedly connected to the discharge port.

[0007] Preferably, the connector includes a female connector, a female connector, and an adapter component; The female connector is rotatably fitted onto both ends of the long pipe and the short pipe, respectively, and the male connector is rotatably fitted onto both ends of the right-angle pipe. The adapter component is installed inside the female connector and the male connector, and the female connector and the male connector are threadedly fitted to each other.

[0008] Preferably, the adapter component includes a single-layer threaded ring and a double-layer threaded ring; The female connector has female grooves at both ends with openings facing the male connector. The single-layer threaded ring is fixed in the female groove, and the outer side of the single-layer threaded ring has a first texture. Both ends of the sub-connector are provided with sub-grooves with openings facing the female connector. The double-layer threaded ring is fixed in the sub-grooves, and the inner wall of the double-layer threaded ring is fixed with a second texture. A third groove is fixed on the inner wall of the female groove, and the second groove is threadedly connected to the first groove and the third groove respectively.

[0009] Preferably, the single-layer threaded ring has a first compression rubber fixed at the end away from the female groove, and the double-layer threaded ring has a second compression rubber fixed at the end away from the female groove.

[0010] Preferably, the upper and lower ends of the valve are connected to the inlet connection pipe and the outlet connection pipe via flanges.

[0011] Preferably, the flange includes a first flange fixed to the inlet connecting pipe and the outlet connecting pipe, and a second flange fixed to the upper and lower ends of the valve; The first flange and the second flange are fixedly connected to each other by bolts.

[0012] The beneficial effects are: 1. To ensure the reliability of the concrete cooling system, special connectors are used to assemble and connect the long pipes, short pipes, and right-angle pipes, thereby avoiding pipe leakage problems that may be caused by traditional welding methods. This connection method not only improves the sealing performance of the system, but also significantly enhances the overall cooling effect.

[0013] 2. To improve the applicability of the concrete cooling system, this solution adopts a multi-layer pre-embedded cooling circulation component design.

This modular design significantly improves the system's adaptability and control accuracy. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] A temperature control structure for large-volume concrete is mainly used to pre-embed a cooling circulation component in the concrete 1. The concrete 1 can then be cooled by the cooling circulation component. The valve 3 can be adjusted according to the required cooling position of the concrete 1 to improve practicality. The cooling circulation component does not require welding, which can avoid leakage caused by welding and improve the cooling effect.

[0018] In this embodiment, the temperature control structure for large-volume concrete includes a cooling circulation assembly installed inside the concrete 1. Several cooling circulation assemblies are arranged vertically and intermittently within the concrete 1. Each cooling circulation assembly is connected to an inlet pipe 2 extending in the left-right direction. Adjacent cooling circulation assemblies are connected by an outlet pipe 12 extending in the up-down direction. In this embodiment, the inlet pipe 2 and outlet pipe 12 form a cooling pipe structure, allowing the cooling circulation assembly to cool the concrete 1 using coolant. Valves 3 are installed on the inlet pipe 2 and outlet pipe 12 to control their opening and closing.

[0019] In this embodiment, valve 3 is a solenoid valve. The structure and principle of the solenoid valve are existing technologies and will not be described in detail here.

[0020] like Figures 1-3 As shown, the feed connection pipes 2 are all connected to the same main pipe 15 extending in the vertical direction. The top of the main pipe 15 is fixed with a feed port 4, and the bottom left side of the cooling circulation assembly is fixed with a discharge port 5. A suction pump is connected to the discharge port 5 so that the coolant in the pipe can be discharged. The coolant enters from the feed port 4, passes through the cooling circulation assembly, and is discharged from the discharge port 5 to remove the heat from the concrete 1.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cooling circulation assembly includes a long pipe 601, a short pipe 602, a right-angle pipe 603, and a connector 604. The long pipe 601 and the right-angle pipe 603, as well as the short pipe 602 and the right-angle pipe 603, are connected by the connector 604 to prevent leakage during welding.

[0022] Specifically, each cooling circulation assembly has two long pipes 601 spaced apart front to back, two short pipes 602 spaced apart left to right, and four right-angle pipes 603. The right-angle pipes 603 are installed on the opposite side of the long pipes 601 and short pipes 602. The long pipes 601, short pipes 602, and right-angle pipes 603 are connected to form a circulation pipe structure that is connected end to end. The right side of the short pipe 602 on the right side of each cooling circulation assembly is fixedly connected to the feed connection pipe 2. The bottom left side of the short pipe 602 on the left side of the bottom cooling circulation assembly is fixedly connected to the discharge port 5. The coolant enters from the feed port 4 and then flows to the discharge port 5 through the circulation pipe structure, so as to realize that the coolant carries away the heat in the concrete 1 and achieves the cooling effect.

[0023] In this embodiment, the opening and closing of valve 3 can realize the opening and closing of the circulation pipe structure of different layers. The flow direction of the coolant can be adjusted according to the cooling position requirements of concrete 1 to achieve better cooling and improve applicability.

[0024] The connector 604 includes a female connector 6041, a female connector 6042, and an adapter assembly. The female connector 6041 is rotatably fitted onto both ends of the long pipe 601 and the short pipe 602, respectively. The female connector 6042 is rotatably fitted onto both ends of the right-angle pipe 603. The adapter assembly is installed inside the female connector 6041 and the female connector 6042. The female connector 6041 and the female connector 6042 are threadedly fitted to each other. When the female connector 6041 and the female connector 6042 abut against each other, they can be threadedly connected through the adapter assembly to improve the connection sealing performance.

[0025] The adapter components include a single-layer threaded ring 701 and a double-layer threaded ring 702; both ends of the female connector 6041 have female grooves 8 with openings facing one end of the male connector 6042, and the single-layer threaded ring 701 is fixed in the female groove 8, with a first groove on the outer side of the single-layer threaded ring 701; both ends of the male connector 6042 have male grooves 9 with openings facing one end of the female connector 6041, and the double-layer threaded ring 702 is fixed in the male groove 9, with a second groove fixed on the inner wall of the double-layer threaded ring 702; a third groove is fixed on the inner wall of the female groove 8. When the female connector 6041 and the male connector 6042 are inserted into each other, the second groove is threadedly connected to the first groove and the third groove respectively, so that the female connector 6041 and the male connector 6042 are relatively fixedly connected.

[0026] In this embodiment, when making a threaded connection, raw rubber tape can be wrapped around the connection between the second thread and the first thread, and between the second thread and the third thread to improve the sealing performance.

[0027] A first compression rubber 10 is fixed to the end of the single-layer threaded ring 701 away from the female groove 8, and a second compression rubber 11 is fixed to the end of the double-layer threaded ring 702 away from the female groove 9, so that when the single-layer threaded ring 701 is inserted into the female groove 9, the first compression rubber 10 can abut against the inner wall of the female groove 9, and when the double-layer threaded ring 702 is inserted into the female groove 8, the second compression rubber 11 can abut against the inner wall of the female groove 8.

[0028] like Figure 6 As shown, the upper and lower ends of valve 3 are connected to the feed connection pipe 2 and the discharge connection pipe 12 through flanges to realize the opening and closing of the feed connection pipe 2 and the discharge connection pipe 12.

[0029] Specifically, the flange includes a first flange 13 fixed on the feed connection pipe 2 and the discharge connection pipe 12, and a second flange 14 fixed on the upper and lower ends of the valve 3; the first flange 13 and the second flange 14 are fixedly connected to each other by bolts so that the valve 3 is fixedly connected to the feed connection pipe 2 or the discharge connection pipe 12.

[0030] Working principle: During use, the cooling circulation assembly is assembled according to the required dimensions of concrete 1. When the female connector 6041 and the male connector 6042 are inserted into each other, the second thread is threadedly connected to the first thread and the third thread respectively, so that the female connector 6041 and the male connector 6042 are relatively fixedly connected. During the insertion process, the first compression rubber 10 can abut against the inner wall of the male groove 9, and when the double-layer threaded ring 702 is inserted into the female groove 8, the second compression rubber 11 can abut against the inner wall of the female groove 8. And during connection, Waterproof tape can be wrapped around the second, first, and third textures to improve the waterproof effect. The connecting valve 3 is then fixedly connected to the inlet connecting pipe 2 or the outlet connecting pipe 12. After completion, the cooling circulation component is placed inside the concrete 1. The coolant can then be discharged from the inlet 4 and the cooling circulation component from the outlet 5 to remove the heat from the concrete 1. By setting the valve 3, the flow direction of the coolant can be adjusted according to the cooling requirements of the concrete 1 to achieve better cooling and improve applicability.
