Description

Technical Field

[0001] This application relates to the field of concrete construction technology, specifically to a prefabricated integrated support and curing concrete formwork. Background Technology

[0002] The curing temperature and humidity conditions of concrete are important factors affecting the cement hydration rate, hydration products, and performance development. Low temperatures, large temperature differences, and dry environments can lead to engineering quality problems such as slow strength gain, drying shrinkage cracking, insufficient strength, and poor durability. Concrete construction in sub-zero winter conditions presents a significant technical challenge that requires further solutions. Current "Code for Winter Construction of Building Engineering" includes measures for winter concrete construction such as heat storage, steam curing, electric heating, and heated sheds. These methods primarily address the issue of concrete curing temperature by insulating the concrete surface and heating the external environment. However, these methods are not only difficult to implement and have poor temperature control, but some also require the construction of sheds, furnaces, and fires, resulting in complex procedures, outdated technology, low energy efficiency, poor environmental impact, high costs, and long construction periods. Summary of the Invention

[0003] This application provides a prefabricated integrated support and curing concrete formwork, which is a brand-new formwork system solution that integrates standardized component assembly, temperature and humidity control and support forming, to solve the problem of in-situ intelligent curing technology for freshly poured concrete in complex environments such as negative temperature, large temperature difference and dryness.

[0004] In a first aspect, this application provides a prefabricated integrated support and curing concrete formwork, comprising:

[0005] Multiple support template panels, each of which has a temperature channel and a humidity channel inside, are arranged in a close array, laid flat and fixed on a pre-set template frame reinforcement beam to form the main body of the concrete template panel.

[0006] The ends of two adjacent support template panels are connected by inter-panel temperature channel connectors, so that the temperature channels inside each support template panel are interconnected, forming a sealed S-shaped heat medium flow channel. The inlet and outlet ends of the heat medium flow channel are connected to the inlet and outlet of the circulation pipe of the temperature control device through preset temperature channel inlet and outlet connectors to form a closed loop of heat medium circulation.

[0007] The temperature control device can control the flow of the heat medium in the heat medium flow channel and exchange heat with the template panel body to control the temperature of the template panel body.

[0008] Multiple anti-clogging nozzles and multiple humidification channel connectors are provided. The multiple anti-clogging nozzles are spaced apart on the main body of the template panel. The multiple anti-clogging nozzles and the multiple humidification channel connectors are interconnected through the humidity channels inside the multiple support template panels to form a multi-point water spraying and humidity adjustment path on the panel surface. The multiple humidification channel connectors are connected to a humidity control and generation device to adjust the humidity of the concrete surface.

[0009] In some possible embodiments, the surface of the support formwork plate that contacts the concrete is smooth, and the side of the support formwork plate away from the concrete is provided with an installation groove to be fixed to the formwork frame reinforcement beam through the installation groove and a pre-set fastener.

[0010] In some possible embodiments, the support template type plate has a cuboid structure, and the multiple support template type plates are provided with multiple through holes perpendicular to the plate surface. The multiple through holes are arranged along the length direction of the support template type plate, and the multiple through holes are connected to the humidity channel.

[0011] In some possible embodiments, the prefabricated integrated support concrete formwork further includes multiple through-hole plugs for sealing the multiple through holes.

[0012] In some possible embodiments, the humidification channel connector is fixedly connected to the through hole of the support template plate by a lock nut, and the outer diameter of the housing of the humidification channel connector matches the diameter of the through hole on the support template plate;

[0013] The housing of the humidification channel connector is provided with a humidity channel connecting hole and a water inlet hole that are interconnected. The humidity channel connecting hole is used to connect the humidity channels of different support template type boards from top to bottom, so as to connect the water inlet hole and the humidity channel. The water inlet hole is connected to the water pump outlet pipe to inject water into the humidity channel of the support template type board.

[0014] In some possible embodiments, both ends of the temperature channel and the humidity channel include channel end caps to seal the temperature channel and the humidity channel. The side of the support formwork plate away from the concrete is provided with a temperature channel connecting hole. The temperature channel connecting hole of the support formwork plate is connected to the inter-plate temperature channel connector and the temperature channel inlet / outlet connector respectively to form a sealed connection to form a reverse-wind heat medium circulation cavity.

[0015] In some possible embodiments, the inter-panel temperature channel connector and the temperature channel inlet / outlet connector are both assembled and fixed to the mounting slot through the fasteners via a preset standard interface. The inter-panel temperature channel connector can fix two adjacent support template plates.

[0016] In some possible embodiments, the inter-plate temperature channel connector includes a temperature channel connection hole, which matches the temperature channel connection hole on the support template plate.

[0017] The length of the inter-board temperature channel connector is the same as the total width of the two support template boards. The inter-board temperature channel connector can connect the temperature channels of two adjacent support template boards and provide a lateral fixed connection for the adjacent support template boards.

[0018] In some possible embodiments, the length of the temperature channel inlet / outlet connector is the same as the width of the support template plate, the temperature channel inlet / outlet connector includes a temperature channel connection hole, and the temperature channel connection hole of the temperature channel outlet connector matches the temperature channel connection hole on the support template plate.

[0019] In some possible embodiments, the anti-clogging nozzle includes a water spray hole, a valve core, a spring, and an opening pressure adjustment screw. The water spray hole is arranged on the surface of the support template plate, and the anti-clogging nozzle is connected to the humidity channel inside the support template plate through its own humidity channel connection hole.

[0020] The valve core and the spray hole form a normally closed valve port under the action of the spring. The spring can control the opening and closing of the normally closed valve port under different water pressures to spray water and humidify the concrete. The opening pressure adjustment screw can control the pressure of different water pressures.

[0021] Compared to related technologies, the integrated support and curing concrete formwork of this application serves as both a support structure and a temperature and humidity control source, offering advantages such as high heat conduction efficiency, low heat dissipation, highly integrated assembly, and simplified procedures. Simultaneously, the temperature channels are evenly distributed across the concrete surface, ensuring uniform heating and preventing concrete cracking caused by temperature stress due to temperature differences, thus guaranteeing the quality of the concrete project. The integrated support and curing concrete formwork provided by this application not only possesses the support and forming function of traditional concrete formwork but also the function of controlling the temperature and humidity conditions for concrete curing, changing the current technical status quo where the formwork structure and heating device are relatively independent.

[0036] It should be noted that the principles of this application are illustrated by example in a suitable computing environment. The following description is based on the specific embodiments of this application that are illustrated, and should not be regarded as limiting other specific embodiments not detailed herein.

[0037] In the following description of this application, "some embodiments" are referred to, which describe a subset of all possible embodiments. However, it is understood that "some embodiments" may be the same subset or different subset of all possible embodiments, and may be combined with each other without conflict.

[0038] In the following description of this application, the terms "first, second, third" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The prefabricated integrated support and curing concrete formwork provided in this application, with its standardized component assembly ratio, integrated temperature and humidity control, and support forming system, effectively solves the technical problem of in-situ intelligent curing of freshly poured concrete under complex environments such as negative temperatures, large temperature differences, and dryness. Figure 1 The image shown is a structural schematic diagram of the prefabricated integrated support and curing concrete formwork provided in an embodiment of this application. Figure 1 In the described embodiment, the prefabricated integrated support and curing concrete formwork mainly includes the following structure:

[0042] Multiple support formwork panels 1, each of which has a temperature channel and a humidity channel inside, are laid out in a close array and fixed on the pre-set formwork frame reinforcement beam 5 to form the main body of the concrete formwork panel.

[0043] The ends of two adjacent support template panels are connected by inter-panel temperature channel connectors 2, so that the temperature channels inside each support template panel 1 are interconnected, forming a sealed S-shaped heat medium flow channel. The inlet and outlet ends of the heat medium flow channel are connected to the inlet and outlet of the circulation pipe of the temperature control generator through preset temperature channel inlet and outlet connectors to form a closed loop of heat medium circulation.

[0044] The temperature control device can control the flow of the heat medium in the heat medium flow channel and exchange heat with the formwork panel body to control the temperature of the formwork panel body. Specifically, the temperature control device can control the heat medium, such as air, to circulate in the temperature channel inside the support formwork panel 1. During the circulation process, the heat medium can directly exchange heat with the support formwork panel 1, so that the temperature control device can control the temperature of the formwork panel body and achieve the effect of temperature control for the curing of freshly poured concrete with formwork.

[0045] Multiple anti-clogging nozzles 3 and multiple humidification channel connectors are provided. The multiple anti-clogging nozzles 3 are spaced apart on the main body of the formwork panel. The multiple anti-clogging nozzles and multiple humidification channel connectors are interconnected through multiple humidity channels inside the support formwork panels to form a multi-point water spraying and humidity control path on the panel surface. The multiple humidification channel connectors are connected to a humidity control generator to regulate the humidity of the concrete surface. Specifically, the humidification channel connectors can be connected to the water pump outlet of the humidity control generator to realize the multi-point water spraying and humidity control function of the concrete surface, achieving the effect of humidity control for the curing of freshly poured concrete with the formwork in place.

[0046] This application discloses a prefabricated integrated support and curing concrete formwork. This concrete formwork serves as both a support structure and a temperature and humidity control source, offering advantages such as high heat conduction efficiency, low heat dissipation, highly integrated assembly, and simplified procedures. Simultaneously, it ensures uniform heating of the concrete, preventing cracking caused by temperature stress due to temperature differences and guaranteeing the quality of the concrete project. The integrated support and curing concrete formwork provided by this application not only possesses the support and forming functions of traditional concrete formwork but also the function of controlling the temperature and humidity conditions for concrete curing, thus changing the current technical status quo where the formwork structure and heating device are relatively independent.

[0047] like Figure 2 The image shown is a side view of the concrete formwork provided in an embodiment of this application. Figure 3 This is a structural schematic diagram of the support template-type plate provided in an embodiment of this application. The following is in conjunction with... Figures 1-3 The structure of the support formwork panel is described in detail. In the embodiments of this application, the support formwork panel 1 can be a cuboid structure with a specific cross-sectional shape, or a long strip-shaped plate profile; multiple support formwork panels 1 are arranged in an array on a cuboid formwork frame reinforcing beam 5, thereby forming the main body of the concrete formwork panel, which can be used to support and shape the concrete structure. The support formwork panel 1 is provided with a temperature channel 11 and a humidity channel 12. The temperature channel 11 can be used to regulate the temperature of the concrete formwork; similarly, the humidity channel 12 can be used to regulate the humidity of the concrete. Figure 1In the illustrated embodiment, the temperature control generator and the humidity control generator are integrated in the temperature and humidity control generator 10. The temperature and humidity control generator is connected to the concrete formwork to control the temperature and humidity of the concrete formwork. The specific control methods and processes will be described in detail in subsequent embodiments and are not limited here.

[0048] In this embodiment, the surface of the support formwork plate 1 in contact with the concrete is flat and smooth, while the side away from the concrete has an installation groove 13. The installation groove 13 allows for the installation of fasteners 100 and fixation to the formwork frame reinforcing beam 5, thereby further securing the support formwork plate to the formwork frame reinforcing beam. To ensure the sealing performance and deformation coordination of the joints between adjacent support formwork plates 1, a tongue-and-groove joint can also be provided on the side of each individual support formwork plate. Please refer to... Figure 4 This is a schematic diagram of the cross-sectional structure of the support template-type plate provided in the embodiments of this application; Figure 4 The sides of each individual support formwork panel 1 are provided with convex tongue-and-groove joints 141 and concave tongue-and-groove joints 142. This convex-and-concave structure better ensures sealing and adjustability during deformation. Meanwhile, temperature channels 11 and humidity channels 12 are located inside each individual support formwork panel 1. The prefabricated integrated support concrete formwork provided in this application may also include an insulation layer 6, which is located at the end of the support formwork panel 1 to insulate the concrete, making the concrete formwork suitable for complex environments such as negative temperatures, large temperature differences, and dryness.

[0049] To achieve standard universality, each support template plate 1 can also be provided with multiple through holes 15. These through holes are spaced apart along the length of the support template plate 1 and are perpendicular to the main body of the template panel. The through holes are connected to the humidity channels of the support template plate 1. The multiple through holes in this application have multiple functions, such as serving as tie rod holes for fixing the template frame, anti-clogging nozzle mounting holes, humidification channel connector mounting holes, temperature sensor mounting holes, humidity sensor mounting holes, or mounting holes for template surface attachments; that is, they can be used to install and fix other functional modules. Specific configurations can be flexibly made according to actual needs.

[0050] However, it should be noted that when the through holes have no special purpose or when it is necessary to maintain the continuity of the humidity channel, through hole plugs 16 need to be installed on multiple through holes to seal them, ensuring the flatness of the template panel body and its airtight continuity with the humidity channel. Simultaneously, when a support template panel 1 has through holes used for tie rod holes, temperature sensor mounting holes, or humidity sensor mounting holes, the humidity channel in that support template panel 1 is interrupted, resulting in a loss of airtightness, and it cannot be used as a humidity control passage panel. Therefore, in this application, the positional relationship between the humidity control panels and other functional panels needs to be staggered in the design; the specific arrangement can be based on actual conditions and is not limited here.

[0051] like Figure 5 The diagram shown is a structural schematic of an embodiment of the temperature channel inlet / outlet connector provided in this application. The temperature channel inlet / outlet connector in this application includes a single-plate temperature channel connector 21. The single-plate temperature channel connector 21 has a channel connection port 211 formed on it to connect with the inlet / outlet of the heat medium flow channel on the support template plate 1 (or, in other words, the channel connection port on the support template plate 1), forming a heat medium circulation loop. Simultaneously, the single-plate temperature channel connector 21 also has a temperature channel inlet / outlet port 213 formed on it to connect with a temperature control generator to achieve heat medium circulation. Figure 5 The single-board temperature channel connector 21 also includes a distribution channel 212 for receiving and storing the heat medium. To ensure the airtightness of the entire circulation loop, end-capping components 215 are installed at both ends of the distribution channel 212 to seal it. Additionally, the single-board temperature channel connector 21 has inwardly recessed mounting grooves 214 for connecting with other functional modules. Figure 5 In the embodiment shown, the heat medium enters the single-panel temperature channel connector 21 from the connection port 211 on the single-panel temperature channel connector 21, and then enters the temperature control device from the temperature channel inlet / outlet port 213. The heat medium adjusted by the temperature control device will re-enter the single-panel temperature channel connector 21 from the temperature channel inlet / outlet port 213, and then enter the support formwork plate 1, thereby realizing the circulation of heat medium and cooling the concrete formwork.

[0052] like Figure 6The diagram shown is a structural schematic of the inter-plate temperature channel connector provided in this application embodiment. The inter-plate temperature channel connector 2 in this application is mainly used to connect the temperature channels 11 in two adjacent support template-type plates 1. The structure of the inter-plate temperature channel connector 2 in this application is similar to that of the temperature channel inlet / outlet connector; wherein, the inter-plate temperature channel connector 2 includes an inter-plate temperature channel connecting member, which also has a channel connection port 221, and is also connected to the support template-type plate 1 through the channel connection port 221; that is, the channel connection port 221 on the inter-plate temperature channel connecting member needs to match the temperature channel connection port on the support template-type plate 1. However, unlike the inter-plate temperature channel connecting member, since the inter-plate temperature channel connector 2 does not need to be connected to the temperature control generating device, the inter-plate temperature channel connector 22 does not need to have an additional temperature channel inlet / outlet port. Similar to the inter-plate temperature channel connector, the inter-plate temperature channel connector 22 also includes a connecting channel 222 for receiving and storing the heat medium. To ensure the airtightness of the entire circulation loop, end-capping components 223 are installed at both ends of the connecting channel 222 to seal the distribution channel. Additionally, the inter-plate temperature channel connector 22 also has inwardly recessed mounting grooves 224 for connecting with other functional modules.

[0053] In the embodiments of this application, the length of each inter-plate temperature channel connector 22 can be the same as the total width of two support template plates 1, thereby connecting two adjacent support template plates 1 using one inter-plate temperature channel connector. However, in other embodiments, it can also be the same as the total width of three or more support template plates 1, which is not limited in this application. The inter-plate temperature channel connector 2 in this application can be fixedly installed on the back end of two adjacent support template plates 1 using fasteners that match the mounting slots 13 on the support template plates 1. While connecting the temperature channels of the two adjacent support template plates 1, it can also provide a lateral fixed connection between the adjacent support template plates 1. The length of the temperature channel inlet / outlet connector can be the same as the width of the support template plate 1, and it is provided with temperature channel connection holes and heat medium pipe connection ports that match the temperature channel connection holes (i.e., the inlet / outlet of the heat medium flow channel) on the support template plate 1. At the same time, the temperature channel inlet / outlet connector can also be installed at the inlet and outlet of the heat medium flow channel using the same installation and fixing method as the inter-plate temperature channel connector 2. The heat medium pipeline connection port can be connected to the inlet and outlet pipelines of the temperature control and generation device, or the temperature channel between the support templates can be connected through external pipelines.

[0054] like Figure 7 The image shown is a three-dimensional schematic diagram of an embodiment of the anti-clogging nozzle provided in this application. Figure 8This is a schematic diagram of an embodiment of the anti-clogging nozzle provided in this application. The housing structure of the anti-clogging nozzle 3 and its installation method with the through hole of the support template plate 1 are similar to those of the humidification channel connector. The anti-clogging nozzle 3 includes a nozzle housing 31, a water spray hole 312, a valve core 32, a spring 33, and an opening pressure adjusting screw 34. The water spray hole 312 is located on the surface of the support template plate 1 and can communicate with the humidity channel of the support template plate 1 through the humidity channel connecting hole 311 on the nozzle housing 31. The valve core 32 can form a normally closed valve port with the water spray hole 312 under the action of the spring preload. During concrete pouring, the valve core 32 can close the water spray hole under the action of the spring preload to prevent uncured concrete from entering the water spray hole. The spring 33 can control the opening and closing of the normally closed valve port under different water pressures to spray water and humidify the concrete, while the opening pressure adjusting screw can control the pressure of different water pressures. Specifically, after the concrete has solidified, water is injected into the humidity channel by a water pump. Under a certain water pressure, the valve core 32 will overcome the spring preload and open the normally closed valve port, thereby spraying water to humidify the concrete. The opening water pressure can be adjusted by adjusting the spring preload using the opening pressure adjusting screw 34.

[0055] like Figure 9 The image shown is a three-dimensional schematic diagram of an embodiment of the humidification channel connector provided in this application. Figure 10 This is a schematic diagram of an embodiment of the humidification channel connector provided in this application. Please refer to... Figures 9-10 The humidification channel connector includes a humidification channel connector housing 41, which is fixedly assembled onto the through hole of the support template plate 1 via a lock nut 300. The outer diameter of the humidification channel connector is the same as the diameter of the through hole of the support template plate 1, forming a tight fit to achieve a seal on the through hole. The humidification channel connector housing 41 is provided with a humidity channel connecting hole 411 and a water inlet hole 412 that are interconnected. The humidity channel connecting hole 411 can connect the humidity channel at the through hole of the support template plate 1 vertically, thereby achieving communication between the water inlet hole 412 and the humidity channel while ensuring a sealing performance. At the same time, the water inlet hole 412 can be connected to the water pump outlet pipe to inject water into the humidity channel of the support template plate 1. When the humidification channel connector is not used for the humidification channel inlet, a plug 42 can be installed at its water inlet to seal it, ensuring the vertical continuity of the humidity channel while acting as a plug to seal the through hole and make the outer surface of the support template plate 1 flat. The structure of the through-hole plug in this application is similar to that of the humidification channel connector. For details, please refer to the foregoing content. It will not be repeated here.

[0056] like Figure 11 The diagram shown is a schematic representation of the concrete formwork assembly provided in an embodiment of this application. Figure 11In this structure, multiple support template-type panels 1 are fixedly connected to the template frame reinforcing beam 5 via mounting slots 13 and fasteners 100. Each support template-type panel 1 includes a temperature channel 11. Temperature channel connectors 2 are installed at both ends of the support template-type panels 1 to connect the two temperature channels 11 of adjacent support template-type panels 1. The temperature channel connector 2 includes an inter-panel temperature channel connecting component, which connects to the support template-type panel 1 via a channel connection port. Simultaneously, after all temperature channels are connected to form a sealed heat medium flow channel, it is necessary to connect to the temperature channel inlet / outlet connector at the inlet / outlet of the heat medium flow channel. The temperature channel inlet / outlet connector also needs to connect to the inlet / outlet of the circulation pipe of the temperature control generator to form a closed-loop heat medium circulation circuit. The temperature channel inlet / outlet connector includes a single-panel temperature channel connector 21 and a temperature channel inlet / outlet port 213 connected to the inlet / outlet of the circulation pipe of the temperature control generator. Figure 11 In the middle, the surface of the support template board 1 also has multiple through holes, and the different through holes have different functions. For example, different through holes are respectively equipped with anti-clogging nozzles 3, humidity channel inlet connectors 4, humidity acquisition devices 7, inner and outer surface temperature acquisition devices 8, tie rod holes 9, or plugs 42, etc.

[0057] like Figure 12 The diagram shown is a schematic representation of the temperature channel connectivity provided in an embodiment of this application. Figure 12 In this configuration, the temperature channels 11 in two adjacent support-type template panels 1 are connected through the channel connection port 221 on the inter-panel temperature channel connector; simultaneously, they are also connected to an external temperature control device through the temperature channel inlet / outlet port 213 on the single-panel temperature channel connector 21. The single-panel temperature channel connector 21 is also connected to the temperature channel 11 through its own channel connection port 211. The inter-panel temperature channel connector also includes a connecting channel 222, and the single-panel temperature channel connector 21 also includes a distribution channel 212.

[0058] like Figure 13 The diagram shown is a schematic representation of the humidity channel connection provided in an embodiment of this application. Figure 13 In the concrete support formwork slab 1, a humidity channel 12 is formed inside, and multiple through holes 15 are formed on the surface of the formwork slab 1. Some of these through holes are into which anti-clogging nozzles 3 or humidity channel inlet connectors 4 are inserted. The anti-clogging nozzles can be opened or closed under different water pressures to spray water and humidify the concrete.

[0059] The integrated support and curing concrete formwork disclosed in this application not only possesses the support and forming function of traditional concrete formwork, but also the function of controlling the temperature and humidity conditions for concrete curing. This changes the current technical status quo where the formwork structure and heating device are relatively independent, proposing a completely new formwork system solution for concrete curing with formwork through a highly integrated technical solution. The integrated support and curing concrete formwork of this application is both a support structure and a temperature and humidity control source, featuring high heat conduction efficiency, low heat dissipation, highly integrated assembly, and simplified procedures. Simultaneously, the temperature channels are evenly distributed on the concrete surface, ensuring uniform heating of the concrete and preventing cracking caused by temperature stress due to temperature differences, thus guaranteeing the quality of the concrete project.

[0060] Furthermore, the integrated support concrete formwork of this application is installed by rapid assembly of standardized components. Compared with traditional concrete formwork, which is mostly made of wood or steel plates and processed and customized according to the required size, it has the advantages of high standardization, quick installation and dismantling, high reusability, wide range of applications, and energy saving and environmental protection.

[0061] The integrated support and curing concrete formwork of this application can not only regulate the curing temperature of concrete, but also regulate the curing humidity at the same time. It has the characteristics of temperature and humidity joint regulation and control, and can comprehensively regulate the curing conditions of concrete. It solves the problem of in-situ intelligent curing technology for freshly poured concrete in complex environments such as negative temperature, large temperature difference, and dryness. It changes the technical status quo of traditional customized concrete formwork with single function, and has the effect of wide application range and strong applicability.

[0062] The integrated support and curing concrete formwork of this application can be equipped with temperature and humidity generating and collecting devices, realizing intelligent concrete curing formwork with self-sensing and autonomous regulation of temperature and humidity. It can be applied to newly poured concrete projects in complex environments such as negative temperatures, large temperature differences, and dryness, solving problems such as slow strength growth and drying shrinkage cracking of concrete under cold and arid climates. It can also be applied to scenarios in conventional environments where it is necessary to improve the early-age strength of concrete, accelerate construction progress, and ensure concrete quality. At the same time, without the temperature and humidity generating device, it can be used as ordinary concrete formwork, which has the advantages of flexible application and wide applicability.

[0063] The above provides a detailed description of a prefabricated integrated support and curing concrete formwork provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
