Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete pouring technology, and in particular relates to a temperature control device for large-volume concrete. Background Technology
[0002] Concrete is mainly made of cement, aggregates, water, and admixtures. When cement comes into contact with water, it undergoes a hydration reaction, releasing a certain amount of heat. For large-volume concrete (such as the foundation slab of high-rise buildings or the foundation of large equipment), the heat generated by hydration is relatively large, resulting in a significant temperature difference between the inside and outside of the concrete. This can easily lead to temperature cracks on the concrete surface, seriously affecting the strength, durability, and impermeability of the concrete, and threatening the safety and normal use of the structure.
[0003] Currently, to address the issue of excessive heat generated by hydration heat, cooling devices are often placed inside the concrete. These devices utilize the circulation of condensate between the inside and outside of the concrete, allowing the condensate to carry away heat and achieve rapid dissipation, thus reducing the risk of temperature cracks. However, these cooling devices cannot monitor the internal temperature of the concrete in real time. When it rains or the ambient temperature decreases, the use of these devices can easily lead to excessively low internal temperatures, slowing down the concrete's setting rate. This, in turn, prevents sufficient evaporation of moisture from the concrete, affecting its strength.
[0004] Therefore, there is an urgent need for a large-volume concrete temperature control device to solve the above problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a large-volume concrete temperature control device that can control the heat dissipation rate of concrete, thereby preventing temperature cracks in the concrete and preventing the concrete from being too cold and affecting its strength.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A large-volume concrete temperature control device is provided, comprising:
[0008] A heat-conducting component includes a heat-conducting rod that penetrates into concrete and a portion of the heat-conducting rod protrudes from the concrete.
[0009] Cooling components are used to blow air and / or spray cooling water onto concrete;
[0010] The temperature control component includes a temperature measuring element and a control element. The temperature measuring element is installed on the heat-conducting rod to measure the temperature inside the concrete. The temperature measuring element is communicatively connected to the control element, and the control element is connected to the cooling component to control the opening and closing of the cooling component.
[0011] Optionally, the end of the heat-conducting rod is provided with a heat-conducting plate that is detachably connected to it, and the heat-conducting plate is sleeved on the heat-conducting rod.
[0012] Optionally, the heat-conducting rod is provided with a screw section, and the heat-conducting plate is provided with a threaded hole, with the screw section passing through the threaded hole and threadedly connected to the threaded hole.
[0013] Optionally, the heat-conducting component also includes a metal template, which encloses a pouring space where concrete is poured and formed, and heat-conducting rods are inserted through the pouring space.
[0014] Optionally, the heat-conducting component also includes multiple heat sinks mounted on the outer wall of the metal template, the multiple heat sinks being arranged circumferentially along the casting space.
[0015] Optionally, the cooling component includes a spray pipe through which cooling water is sprayed onto the concrete. The spray pipe is equipped with a control valve for controlling the on / off state of the spray pipe, and the control valve is electrically connected to a control unit.
[0016] Optionally, the cooling assembly also includes a spray head and a water tank, with the spray head positioned on top of the concrete and the water tank connected to the spray head via a spray pipe.
[0017] Optionally, the cooling assembly includes a blower element, which is electrically connected to the control unit.
[0018] Optionally, the temperature control assembly also includes an alarm, which is communicatively connected to the temperature sensor.
[0019] Alternatively, the heat-conducting rod may be made of steel.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This invention provides a temperature control device for large-volume concrete.
[0022] The heat-conducting rod penetrates the concrete and partially protrudes from it, thus transferring heat from the concrete's interior to the exterior, accelerating heat dissipation and preventing temperature cracks. A temperature sensor mounted on the heat-conducting rod monitors the concrete's internal temperature in real time. When the internal temperature is too high, the controller activates a cooling component to blow air and / or spray cooling water onto the concrete. The airflow around the concrete accelerates heat dissipation; the cooling water evaporates upon contact with the concrete's high temperature, carrying away heat and lowering the concrete temperature. The cooling component, working in conjunction with the heat-conducting rod, rapidly reduces the concrete's temperature, preventing temperature cracks. When the temperature sensor detects a low concrete temperature, the controller deactivates the cooling component, stopping the airflow and / or water spraying, thus reducing the rate of heat dissipation and preventing excessively low concrete temperatures from affecting its strength.

Therefore, they should not be construed as limitations on this utility model.
[0030] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a temperature control device for large-volume concrete, which can control the heat dissipation rate of concrete, thereby preventing temperature cracks in the concrete and preventing the concrete from becoming too cold and affecting its strength.
[0033] See Figure 1 and Figure 2 The large-volume concrete temperature control device includes a heat-conducting component 1, a cooling component 2, and a temperature control component 3. The heat-conducting component 1 includes a heat-conducting rod 11, which is inserted into the concrete and partially protrudes from the concrete. The cooling component 2 is used to blow air and / or spray cooling water onto the concrete. The temperature control component 3 includes a temperature measuring element 31 and a control element 32. The temperature measuring element 31 is disposed on the heat-conducting rod 11 and is used to measure the internal temperature of the concrete. The temperature measuring element 31 is communicatively connected to the control element 32, and the control element 32 is connected to the cooling component 2 to control the opening and closing of the cooling component 2.
[0034] The large-volume concrete temperature control device provided in this embodiment has a heat-conducting rod 11 that penetrates the concrete and partially protrudes from it. Therefore, the heat-conducting rod 11 can conduct heat from inside the concrete to the outside, accelerating the heat dissipation rate and preventing temperature cracks from forming. A temperature sensor 31 is installed on the heat-conducting rod 11 to monitor the internal temperature of the concrete in real time. When the internal temperature of the concrete is too high, the control unit 32 activates the cooling component 2 to blow air and / or spray cooling water onto the concrete. Blowing air accelerates the airflow around the concrete, speeding up heat dissipation. The cooling water evaporates upon contact with the concrete at its high temperature, carrying away some heat and thus lowering the concrete temperature. The cooling component 2, in conjunction with the heat-conducting rod 11, allows the concrete temperature to be rapidly reduced, preventing temperature cracks. When the temperature sensor 31 detects a low concrete temperature, the control unit 32 deactivates the cooling component 2, stopping the blowing air and / or spraying of cooling water onto the concrete, reducing the heat dissipation rate and preventing excessively low concrete temperatures from affecting the concrete's strength.
[0035] In this embodiment, see Figure 1 and Figure 2 Multiple heat-conducting rods 11 are provided and arranged in a matrix inside the concrete, so that the heat from various parts inside the concrete can be conducted to the external space, thus improving the heat conduction effect.
[0036] For example, the heat-conducting rod 11 is made of steel.
[0037] For example, see Figure 1 and Figure 2 The control component 32 is a microcontroller. The temperature measuring component 31 is connected to the control component 32 via a signal line 33. The temperature measuring component 31 transmits the temperature data of the concrete to the microcontroller via a communication signal. The microcontroller controls the opening and closing of the cooling component 2 based on the received data.
[0038] Further, see Figure 1 and Figure 2 Multiple temperature measuring elements 31 are provided on the heat-conducting rod 11. The multiple temperature measuring elements 31 are arranged at intervals along the extension direction of the heat-conducting rod 11 and are connected to each other by signal lines 33. The temperature at the edge of the concrete is lower than the temperature at the center of the concrete. The arrangement of multiple temperature measuring elements 31 can accurately measure the temperature of various parts inside the concrete to accurately control the heat dissipation rate of the concrete.
[0039] Optionally, see Figure 1 and Figure 2 The heat-conducting rod 11 has a heat-conducting plate 12 detachably connected to its end, and the heat-conducting plate 12 is sleeved on the heat-conducting rod 11. The cross-sectional area of the heat-conducting plate 12 is larger than that of the heat-conducting rod 11, thereby increasing the heat diffusion area at the end of the heat-conducting rod 11 and further improving the rate of heat dissipation from the concrete. When the concrete temperature is low, removing the heat-conducting plate 12 can reduce the heat dissipation rate of the heat-conducting rod 11, allowing the concrete temperature to rise.
[0040] In this embodiment, the heat-conducting rod 11 is provided with a screw portion, and the heat-conducting plate 12 is provided with a threaded hole. The screw portion passes through the threaded hole and is threadedly connected to the threaded hole. This arrangement enables a detachable connection between the heat-conducting rod 11 and the heat-conducting plate 12, and also ensures that the heat-conducting rod 11 and the heat-conducting plate 12 can make close contact when connected, so as to form a continuous heat conduction path between the heat-conducting rod 11 and the heat-conducting plate 12, thus ensuring the heat dissipation effect.
[0041] For example, see Figure 1 and Figure 2 The heat-conducting plate 12 is a steel plate with a circular cross-sectional shape.
[0042] Optionally, see Figure 1 and Figure 2The heat-conducting component 1 also includes a metal template 13, which encloses a pouring space 131. Concrete is poured and formed within the pouring space 131, and a heat-conducting rod 11 passes through the pouring space 131. The metal template 13 serves as the template for concrete pouring. Compared to existing templates made of wood, the metal template 13 has better thermal conductivity and can accelerate the heat dissipation rate of the concrete.
[0043] For example, the metal template 13 is made of steel.
[0044] Furthermore, before pouring concrete into the pouring space 131, the heat-conducting rod 11 is first installed into the pouring space 131 to ensure the contact effect between the heat-conducting rod 11 and the concrete.
[0045] In this embodiment, see Figure 1 and Figure 2 The heat-conducting component 1 also includes multiple heat sinks 14 installed on the outer wall of the metal formwork 13, which are arranged circumferentially along the pouring space 131. The heat sinks 14 are mainly made of metal materials such as aluminum alloy, brass, bronze, or copper alloy, and have good thermal conductivity. Moreover, the heat sinks 14 are arranged in multiple layers in the vertical direction, which can increase the heat dissipation area of the metal formwork 13, thereby allowing the heat emitted by the concrete to be more effectively dissipated into the surrounding air through the heat sinks 14, further accelerating the heat dissipation rate of the concrete.
[0046] For example, heat sink 14 is made of aluminum.
[0047] For example, see Figure 1 and Figure 2 The large-volume concrete structure is a concrete column with a rectangular cross-section. Four heat sinks 14 are provided, and the four heat sinks 14 are distributed on the four sides of the concrete column.
[0048] In an optional embodiment, see [link to relevant documentation] Figure 1 and Figure 2 The cooling component 2 includes a spray pipe 211 through which cooling water is sprayed onto the concrete. A control valve 212 is installed on the spray pipe 211 to control its opening and closing. The control valve 212 is electrically connected to a control element 32. The control element 32 controls the opening and closing of the control valve 212. When the control valve 212 is open, cooling water flows within the spray pipe 211 and sprays onto the concrete to cool it. When the control valve 212 is closed, the spray pipe 211 is cut off, stopping the spraying and cooling of the concrete, allowing the concrete temperature to rise again.
[0049] In this embodiment, see Figure 1 and Figure 2The cooling component 2 also includes a spray head 213 and a water storage tank 214. The spray head 213 is located on top of the concrete, and the water storage tank 214 is connected to the spray head 213 via a spray pipe 211. The water storage tank 214 provides a continuous flow of water to the spray pipe 211, and the spray head 213 sprays the cooling water onto the concrete in a jet pattern, increasing the contact area between the concrete and the cooling water and improving the cooling rate of the concrete.
[0050] In another alternative embodiment, see [link to relevant documentation]. Figure 1 and Figure 2 The cooling component 2 includes a blower 22, which is electrically connected to a control component 32. The control component 32 controls the opening and closing of the blower 22. When the blower 22 is turned on, it blows air onto the concrete to reduce the temperature of the concrete.
[0051] For example, the blower 22 is a fan with an adjustable speed to control the rate of cooling of the concrete by adjusting the wind force blowing onto the concrete.
[0052] In another alternative embodiment, see [link to relevant documentation]. Figure 1 and Figure 2 The cooling component 2 includes a spray pipe 211 and a blower 22 to blow air and spray cooling water onto the concrete, which significantly improves the rate of heat dissipation of the concrete.
[0053] Specifically, when the concrete temperature reaches the set temperature, the control unit 32 controls the blower 22 to start to dissipate heat from the concrete; if the concrete temperature continues to rise, the control unit 32 can control the control valve 212 to open, so that cooling water is sprayed onto the concrete through the spray pipe 211 to improve the cooling effect on the concrete.
[0054] In this embodiment, see Figure 1 and Figure 2 Multiple sets of cooling components 2 are provided, and these sets are spaced apart along the circumference of the concrete to ensure uniform heat dissipation from the concrete. For example, see [reference needed]. Figure 1 and Figure 2 The cooling component 2 is provided in four sets. The large-volume concrete structure is a concrete column with a rectangular cross-section. The four sets of cooling components 2 are located at the four corners of the concrete column.
[0055] Optionally, see Figure 1 and Figure 2 The temperature control component 3 also includes an alarm 34, which is communicatively connected to the temperature measuring element 31. When the temperature measuring element 31 detects that the concrete temperature is low, the alarm 34 will sound an alarm to remind the staff to take measures to reduce the heat dissipation rate, such as separating the heat-conducting plate 12 from the heat-conducting rod 11.
[0056] For example, the alarm 34 is a buzzer or a warning light, and the alarm 34 is connected to the temperature measuring element 31 via a signal line 33.
[0057] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
