Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a lining formwork panel temperature control device for pouring special-shaped plain concrete structures. Background Art

[0002] Fair-faced concrete is widely used in modern architecture for its natural texture. However, traditional formwork systems rely on hand-carving or simple molds, resulting in low texture precision and an inability to reproduce complex geometric forms. With the rise of parametric design, the demand for high-precision, special-shaped surfaces in building facades has surged.

[0003] However, the artistic expression is limited due to the easy deformation of wooden formwork, the high cost of steel formwork and the difficulty in processing detailed textures. At the same time, the lining formwork panels made of materials such as hard plastic polyurethane can achieve complex textures, but lack effective high-temperature protection measures. During the high-strength concrete pouring process, the hydration heat generated by the concrete pouring cannot be dissipated in time, causing the lining formwork panels to soften, deform or even debond due to high temperature, seriously affecting the construction quality of fair-faced concrete. Summary of the Invention

[0004] The present invention provides the following technical solution: a lining formwork panel temperature control device for casting special-shaped plain concrete structures, comprising: a lining formwork panel, a mounting groove is provided on the side wall of the lining formwork panel, a cooling pipe is installed in the inner cavity of the mounting groove, the upper part of the cooling pipe is a straight cooling pipe, and the lower part of the cooling pipe is a bent cooling pipe, a temperature control system is installed on the surface of the lining formwork panel, a steel frame is provided on the outer side of the lining formwork panel, a water tank is installed on the surface of the steel frame, an inlet pump is installed on the upper surface water outlet of the water tank, a water outlet pump is installed on the upper surface water inlet of the water tank, the inlet pump is connected to the water inlet of the cooling pipe, and the water outlet pump is connected to the water inlet of the cooling pipe.

[0005] Preferably, a water inlet pipe is installed on the upper surface of the water tank, and a sealing plug is installed on the surface of the water inlet pipe. When the sealing plug is opened, water can be injected into the water tank through the water inlet pipe.

[0006] Preferably, a water outlet pipe is installed on the surface of the water tank, and a sealing cover is screwed on the surface of the water outlet pipe. When the water outlet pipe is opened, the water in the water tank can be discharged, thereby replacing the cooling water in the water tank.

[0007] Preferably, a semiconductor refrigeration module is installed on the surface of the water tank, a heat dissipation frame is installed on the surface of the water tank, and fans are evenly distributed on the surface of the heat dissipation frame. Holes are drilled at corresponding positions on the surface of the water tank and the semiconductor refrigeration module, bolts are inserted and nuts are used to tighten the semiconductor refrigeration module to avoid damaging the semiconductor refrigeration module or the water tank. The heat dissipation frame is aligned with the installation position on the surface of the water tank, holes are drilled at pre-marked positions, and then the heat dissipation frame is fixed to the surface of the water tank with bolts. Ensure that the heat dissipation frame is installed firmly and horizontally, mark the installation position of the fans on the surface of the heat dissipation frame, ensure that they are evenly distributed to achieve good heat dissipation effect, and use appropriate The fan is fixed to the heat sink with screws, allowing the fan to be installed. When the liquid in the water tank needs to be cooled, the semiconductor refrigeration module is activated. The semiconductor refrigeration module begins to work according to the set temperature parameters. Through the Peltier effect, it absorbs heat at the cooling end, lowering the temperature of the liquid in the water tank. The heat generated during the operation of the semiconductor refrigeration module is transferred to the surface of the water tank through contact with the surface of the water tank, and then from the surface of the water tank to the heat sink. The heat sink, with its large heat dissipation area and good thermal conductivity, disperses the heat, preparing for subsequent heat dissipation. As heat accumulates on the heat sink, the fans evenly distributed on the surface of the heat sink are activated. The fans begin to rotate, forming an airflow. The airflow generated by the fans blows through the heat sink fins of the heat sink, carrying away the heat. Through forced convection, the heat dissipation efficiency is greatly improved, so that the heat dissipation rack can continuously and effectively dissipate the heat conducted from the water tank to the surrounding environment. If the temperature in the water tank has not reached the set range, the semiconductor refrigeration module and the fan will continue to operate. When the temperature in the water tank reaches the set range, according to the specific control strategy, the semiconductor refrigeration module can reduce power or stop running, and the fan can also adjust the speed or stop rotating according to the heat dissipation requirements.

[0008] Preferably, an extension pipe is installed at the bottom of the water inlet pump, and the water inlet of the extension pipe is located at the bottom of the inner cavity of the water tank. The extension pipe enables the water inlet pump to draw the water at the bottom of the water tank into the cooling pipe, and the water outlet pump will inject the water in the cooling pipe into the upper part of the inner cavity of the water tank, thereby avoiding the high temperature of the water drawn in by the water inlet pump.

[0009] Preferably, the interfaces of the water inlet pump and the water outlet pump are both installed with connecting pipes, the surfaces of the connecting pipes are both installed with fixed sleeves, and the interfaces of the cooling pipes are all inserted into the inside of the fixed sleeves, so that the water inlet pump, the water outlet pump and the cooling pipe can be connected, and the cooling pipe can be pulled out of the fixed sleeve, so that the cooling pipe can be easily disassembled.

[0010] Preferably, an extrusion tube is installed on the surface of the fixed sleeve, a fastening sleeve is screwed on the surface of the extrusion tube, a water pipe is inserted into the inner cavity of the extrusion tube, and the water pipe penetrates the surface of the lining mold panel and is connected to the cooling pipe at the corresponding position. The rotating fastening sleeve can move along the extrusion tube, thereby driving the extrusion tube to extrude the interface of the cooling pipe, thereby improving the stability of the connection of the cooling pipe.

[0011] Preferably, the temperature control system includes a central controller and a temperature detector. The probe of the temperature detector extends into the interior of the mold lining panel. The central controller is connected to the temperature detector via a wire. The central controller is mounted on the outer surface of the mold lining panel. Before using the temperature control system, the appearance of the central controller needs to be inspected to ensure that there is no physical damage, such as cracks in the outer shell and deformation of the interface. The central controller needs to be functionally tested to confirm that it can normally receive signals, process data, and issue control instructions according to the set logic. For example, by connecting test equipment, simulating the input temperature signal, and checking whether the output control signal is correct. According to the installation environment of the outer surface of the mold lining panel, appropriate installation tools and fixtures, such as screws and brackets, are prepared. The probe portion of the temperature detector is inspected to ensure that the probe is intact and undamaged and can accurately sense temperature changes. The wires of the temperature detector are inspected to ensure that the wires are firmly connected and there are no breaks or short circuits. Use a multimeter or other tool to verify that the temperature probe's specifications and performance indicators meet the requirements for temperature detection within the lining panel, such as detection range and accuracy. When installing the temperature control system, determine the optimal insertion location for the temperature probe based on the lining panel's structure and the critical areas where temperature monitoring is required. At the determined location, drill a hole appropriately and carefully insert the temperature probe into the lining panel. Ensure the probe is securely installed and prevents movement or dislodging during use. Ensure the probe is sealed at the probe installation location to prevent external factors from entering the lining panel and affecting temperature detection accuracy, while also preventing leakage of materials from within the panel. Select a suitable location on the lining panel's exterior surface to install the central controller, one that is easily accessible for wire connection to the temperature probe. Use the prepared installation tools and fixtures to securely mount the central controller on the exterior of the lining panel. Ensure the installation is secure and will not loosen due to vibration or other external forces. Connect the temperature probe wires to the corresponding connectors on the central controller. During the connection process, ensure that the interface is tightly connected and operate in the correct wiring method to prevent wrong wiring. After the connection is completed, check again whether the wire connection is firm. You can gently pull the wire to check whether there is any looseness. After the installation is completed, the temperature control system needs to be tested. The temperature control system needs to be powered on to check whether the central controller and temperature detector are working properly.The central controller should be able to normally identify the initial temperature signal from the temperature detector and display it correctly on its display screen. By changing the temperature of the lining mold panel, observe whether the temperature detector can accurately sense the temperature change and transmit the signal to the central controller in time, and whether the central controller can respond correctly according to the set temperature control logic. If it is found during the test that the temperature detection is inaccurate or the control logic of the central controller does not meet expectations, calibrate the temperature detector according to the equipment's operating manual, or adjust the control parameters of the central controller until the entire temperature control system is working normally. The probe of the temperature detector is in direct contact with the material inside the lining mold panel. Due to the thermal sensitivity of the probe, it can sense the temperature change inside the lining mold panel in real time. The temperature detector converts the sensed temperature signal into an electrical signal. The size of the electrical signal corresponds to the detected temperature value. The temperature detector transmits the converted electrical signal to the central controller through a wire. During the transmission process, the signal propagates along the wire in the form of an electrical pulse to maintain the stability and accuracy of the signal and minimize the impact of external electromagnetic interference on the signal. The central controller The central controller receives the electrical signal from the temperature detector through the corresponding signal receiving port. The central controller compares the analyzed temperature value with the preset temperature threshold. If the temperature value is within the set normal range, the central controller maintains the current state and does not perform additional operations. If the temperature value exceeds the set upper limit, the central controller makes a corresponding decision based on the internal preset control logic. When the temperature is too high, it decides to start the cooling pipe for cooling. The central controller transmits the generated control instructions to the connected external device through the corresponding output port. The external device performs corresponding operations based on the received instructions, such as adjusting power, turning on or off, etc., to control the temperature of the lining mold panel. The central controller repeats the above-mentioned temperature detection, signal transmission, processing and decision-making process at a certain time interval, and continuously monitors the temperature changes of the lining mold panel. Based on the results of each monitoring, the central controller continuously adjusts the control instructions to ensure that the temperature of the lining mold panel always remains within the set range. For example, if the temperature drops too quickly during the cooling process, the central controller will appropriately reduce the power of the cooling equipment to avoid the temperature being too low.

[0012] Preferably, the steel frame includes vertical keels, transverse keels and padding steel plates, the lower part of the steel frame is the transverse keel, the bottom of the transverse keel is evenly distributed with vertical keels, the bottom of the vertical keel is installed with a padding steel plate, the bottom of the padding steel plate is installed with a wooden formwork, and the lining formwork panel is attached to the inner side of the wooden formwork.

[0013] Preferably, a sealing plate is installed at the bottom of the wooden formwork, threaded rods are evenly distributed on the upper surface of the steel frame, the lower parts of the threaded rods are screwed to the upper surface of the wooden formwork, and the surfaces of the lining formwork panel, wooden formwork, lining steel plate and steel frame are all provided with cooling water inlets and outlets, and cooling water is injected into the cooling pipe in the lining formwork panel through the cooling water inlets and outlets.

[0014] In summary, compared with the prior art, the present invention provides a lining form panel temperature control device for pouring special-shaped plain concrete structures, which has the following beneficial effects: The present invention starts the water inlet pump to inject cooling water into the cooling pipe, and the lining form panel can be cooled through the cooling pipe. The temperature value in the lining form panel can be compared with a preset temperature threshold through the temperature control system. If the temperature value exceeds the set upper limit, the temperature control system can make a corresponding decision based on the internal preset control logic. When the temperature is too high, it decides to start the cooling pipe to cool the lining form panel, which can prevent the high heat emitted by high-strength concrete from damaging the lining form panel, thereby preventing the lining form panel from being damaged due to excessive hydration heat generated during the concrete pouring process, thereby preventing the lining form panel from being damaged due to excessive surface temperature of the panel, thereby ensuring the construction quality of the plain concrete and increasing the turnover number of the lining form panel.

[0041] dOperation steps and precautions: S1: Master mold production - SLS 3D printing nylon master mold with a layer thickness of 0.1mm and a fluorocarbon release agent film with a thickness of 20μm on the surface; S2: Liner molding - Place the master mold into the steel frame 3, set a cooling pipe 10 in the gap between the two, inject the polyurethane mixture, and then start the vacuum pump to a vacuum degree of -0.08MPa to remove bubbles; S3: Formwork assembly - obtain the hardened lining formwork panel 1 with the cooling pipe 10 inside, then fasten the cooling pipe 10 to the wooden formwork 7 with tie hooks, and glue the steel mesh to the joint with the structural adhesive Sika 291; S4: Intelligent control - During pouring, the PLC controller adjusts the cooling water valve opening according to the temperature measurement data to maintain the lining mold temperature at 40-60℃.

[0042] eReplaceable parts: The material of the steel frame 3 can be replaced with aluminum alloy 6061-T6, and the keel section needs to be increased to 100×80mm. The wooden formwork 7 can be replaced with a phenolic resin board, and the thickness needs to be increased to 18mm.
