Description

Technical Field

[0001] This utility model relates to the field of concrete formwork pouring construction, and in particular to an intelligent temperature control system for internal circulation concrete pouring formwork. Background Technology

[0002] Currently, most cast-in-place concrete structure formwork in the industry adopts a scattered support and dismantling model. In cold weather, considering the impact of the environment on the sides of the concrete structure, simple insulation measures are applied to the side formwork gaps or the formwork surface without theoretical guidance or support.

[0003] Compared with automatic heating and temperature measurement formwork systems, traditional formwork systems have the following disadvantages: the scattered support and dismantling mode results in fewer formwork turnovers, higher capital investment, and poorer economic efficiency, and requires more strenuous operation for construction workers; traditional formwork systems lack monitoring of the temperature of the concrete side, and if traditional temperature measurement methods such as thermometers are used, the measurements will be inaccurate and the data will be inconvenient to view, which cannot effectively guide on-site curing. This may cause excessive temperature difference between the inner and outer surfaces of the concrete during hydration, leading to cracks and seriously damaging the integrity and stability of the concrete structure. Utility Model Content

[0004] The main purpose of this utility model is to provide an intelligent temperature control system for concrete pouring formwork, which solves the problems of low turnover efficiency of scattered formwork, low accuracy of concrete pouring temperature monitoring, and difficulty in controlling temperature differences.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an intelligent temperature control system for internal circulation concrete pouring formwork, including a formwork assembly, a temperature monitoring module, an internal circulation heating module, and an intelligent temperature control module. The formwork assembly consists of a panel, channel steel, aluminum beams, and tie rods, used to form the concrete pouring outline. The temperature monitoring module is located on the inner side of the panel and is fixed inside the concrete after pouring. The temperature monitoring module is electrically connected to the intelligent temperature control module to collect temperature information. The internal circulation heating module is located on the outer surface of the panel and is electrically connected to the intelligent temperature control module to receive temperature adjustment signals.

[0006] In the preferred embodiment, the template assembly consists of a panel, a main keel, and a secondary keel forming a hierarchical support system. The secondary keel includes multiple parallel longitudinal aluminum beams spaced apart along the length of the panel, with the inner side of each aluminum beam abutting against the outer side of the panel. The main keel includes multiple parallel transverse channel steels spaced apart along the height of the panel, with their inner sides orthogonally abutting against the outer sides of the aluminum beams. The aluminum beams and channel steels are rigidly connected at the intersection nodes by bolt assemblies, with the bolt axis perpendicular to the panel plane.

[0007] In the preferred embodiment, multiple tie rods are provided at the intersection nodes. These tie rods pass through the channel steel, aluminum beam, and panel, and extend into the inner side of the panel for a certain distance. The tie rods achieve the fastening constraint of the template assembly through the gaskets at both ends and the reinforcing bolt structure.

[0008] In the preferred embodiment, the template assembly also includes a suspension assembly, which includes a U-shaped hook and a load-bearing steel plate welded to its open end. The load-bearing steel plate is adapted to the structure of the inner web of the aluminum beam, and the web is clamped and fixed by bolts. The U-shaped hooks are symmetrically arranged on both sides of the top of the panel.

[0009] In the preferred embodiment, the temperature monitoring module has the following structure: multiple vertical ribs parallel to the aluminum beam are provided on the inner side of the panel, each vertical rib is welded to the inner extension end of the corresponding longitudinal tie rod, multiple embedded temperature sensors are symmetrically arranged on the vertical ribs to form a temperature measurement unit matrix, and each embedded temperature sensor is connected to the external intelligent temperature control module of the template assembly through lead wires.

[0010] In the preferred embodiment, the embedded temperature sensors are arranged in a three-point array on the vertical reinforcing bar, with the embedded temperature sensors at both ends symmetrically arranged at monitoring points at a specific distance from the concrete pouring end face, and the embedded temperature sensor in the middle arranged at the center of the concrete pouring height.

[0011] In the preferred embodiment, the embedded temperature sensor is connected to the vertical rib via a connecting shell. The embedded temperature sensor is installed inside a sealing sleeve. One end of the sealing sleeve is provided with a sealing tube for passing through and protecting the lead wire. A connecting buckle is provided on one side of the sealing sleeve.

[0012] The sealing sleeve is made of thermally conductive material.

[0013] In the preferred embodiment, the internal circulation heating module includes heating devices located on both sides of the top of the panel and hot water pipes connected thereto. The hot water pipes are led out from one side of the heating device, pass around the ends of multiple aluminum beams in an S-shaped path, and then connect to the other side of the heating device to form a closed hot water internal circulation heating loop.

[0014] In the preferred embodiment, the internal circulation heating module is connected to the intelligent temperature control module through a communication unit, and the heating devices on both sides are electrically connected to two communication chips respectively, so as to communicate with the intelligent temperature control module through the communication chips.

[0015] In the preferred embodiment, the communication chip uses an NB-IO communication module to connect with the intelligent temperature control module, so as to communicate with the host computer or host network through the intelligent temperature control module.

[0016] This utility model provides an intelligent temperature control system for internal circulation concrete pouring formwork, which has the following advantages: precise temperature control and improved concrete quality: by real-time monitoring of the internal temperature distribution of concrete through an embedded temperature sensor matrix, combined with the intelligent temperature control module to dynamically adjust the heating strategy, the temperature difference between the inside and outside of the concrete during the hydration process and the cooling rate are effectively controlled, significantly reducing the risk of cracks caused by temperature stress and ensuring the integrity and durability of the structure.

[0017] Modular design improves construction efficiency: The formwork components adopt a pre-assembled hierarchical support system, combined with the overall hoisting function of the suspension components, which reduces the amount of repetitive disassembly and assembly work of traditional scattered formwork, greatly shortens the construction cycle, reduces labor costs, and increases the turnover rate of formwork, making it more economical.

[0018] The heating method is highly efficient, energy-saving, and environmentally friendly: Through continuous water circulation, heat is evenly distributed throughout the system, avoiding localized overheating or uneven heating. The circulation system reduces heat loss, resulting in high thermal energy utilization. By recovering waste heat or rapidly transferring heat to areas of demand, energy consumption is significantly reduced, leading to lower long-term operating costs. The circulating water flow reduces the risk of dry burning, and the relatively stable system pressure minimizes the risk of safety hazards caused by sudden pressure increases. The high energy efficiency ratio reduces fossil fuel consumption or electricity demand, indirectly reducing carbon emissions and aligning with green energy-saving trends.

[0019] Intelligent remote monitoring: Based on NB-IoT communication technology, it realizes real-time data transmission, supports remote monitoring and early warning functions, and construction management personnel can grasp temperature data and equipment status in real time through the upper platform, quickly respond to abnormal situations, and improve the level of intelligence in construction management.

[0020] High reliability and durability: The temperature sensor adopts a sealed sleeve protection design to ensure stable operation under the impact of concrete pouring; the formwork assembly is reinforced by orthogonal rigid connection of main and secondary keels and tie rods, which makes the structure stable, adaptable to complex construction environments and extend service life.

Detailed Implementation

[0029] Example 1

[0030] like Figures 1-6 As shown, an intelligent temperature control system for concrete pouring formwork includes a formwork assembly, a temperature monitoring module, an internal circulation heating module, and an intelligent temperature control module 100. The formwork assembly consists of a panel 1, a channel steel 2, an aluminum beam 3, and tie rods 4, used to form the outline of concrete pouring. The temperature monitoring module is located on the inner side of the panel 1 and is fixed inside the concrete after pouring. The temperature monitoring module is electrically connected to the intelligent temperature control module 100 to collect temperature information. The internal circulation heating module is located on the outer surface of the panel 1 and is electrically connected to the intelligent temperature control module 100 to receive temperature adjustment signals.

[0031] This application involves positioning each component of the template on a pre-erected platform according to the design drawings and drawing positioning lines, then installing and positioning the panel 1 with each channel steel 2 and aluminum beam 3, forming a concrete pouring template and external support keel structure, installing U-shaped hooks 7 for hoisting the entire template, forming a template structure that can be hoisted as a whole, fixing the internal circulation heating module on the panel 1, hoisting the template assembly with the internal circulation heating module to the concrete structure position, installing tie rods 4 and various fasteners to fix the template position, and then installing a temperature monitoring module on the inside of the panel 1.

[0032] This solution differs from the traditional scattered formwork solution. By pre-assembling, it saves time on the formwork construction site. At the same time, the platform facilitates line marking and positioning, improving construction accuracy and convenience. The formwork components and their internal circulation heating modules can be hoisted and reused as a whole, improving construction efficiency and reducing the labor costs of repeated formwork assembly and disassembly.

[0033] In the preferred embodiment, the template assembly consists of a panel 1, a main keel, and a secondary keel forming a hierarchical support system. The secondary keel includes multiple parallel longitudinal aluminum beams 3 arranged at intervals along the length of the panel 1, with the inner side of each aluminum beam 3 abutting against the outer side of the panel 1. The main keel includes multiple parallel transverse channel steels 2 arranged at intervals along the height of the panel 1, with their inner sides orthogonally abutting against the outer sides of the aluminum beams 3. The aluminum beams 3 and the channel steels 2 are rigidly connected at the intersection nodes by bolt assemblies, with the bolt axis perpendicular to the plane of the panel 1.

[0034] The main keel and secondary keel are orthogonally abutted against the outer side of panel 1 to form the support structure of panel 1. The force of the external support is evenly applied to panel 1 through multiple aluminum beams 3 and channel steel 2 to form a reliable concrete pouring outline.

[0035] In the preferred embodiment, multiple tie rods 4 are provided at the intersection nodes. The tie rods 4 pass through the channel steel 2, aluminum beam 3, and panel 1, and extend into the inner side of panel 1 for a certain distance. The tie rods 4 achieve the fastening constraint of the template assembly through the structure of the end gaskets 5 and reinforcing bolts 6.

[0036] In the preferred embodiment, the template assembly also includes a suspension assembly, which includes a U-shaped hook 7 and a load-bearing steel plate 8 welded to its open end. The load-bearing steel plate 8 is adapted to the inner web structure of the aluminum beam 3, and the web is clamped and fixed by bolts. The U-shaped hook 7 is symmetrically arranged on both sides of the top of the panel 1.

[0037] The stress points of the template components are calculated, and the hoisting connectors are installed at these points. The U-shaped hook 7 distributes the concentrated pressure generated during hoisting to the surface of the inner web of the aluminum beam 3 through the bearing steel plate 8, thereby enhancing the structural safety of the hoisting structure.

[0038] In the preferred embodiment, the temperature monitoring module has the following structure: multiple vertical ribs 11 parallel to the aluminum beam 3 are provided on the inner side of the panel 1. Each vertical rib 11 is welded to the inner extension end of the corresponding longitudinal tie rod 4. Multiple embedded temperature sensors 9 are symmetrically arranged on the vertical ribs 11 to form a temperature measurement unit matrix. Each embedded temperature sensor 9 is connected to the external intelligent temperature control module 100 of the template assembly through a lead wire 10.

[0039] In the preferred embodiment, the embedded temperature sensors 9 are arranged in a three-point array on the vertical rib 11, with the embedded temperature sensors 9 at both ends symmetrically arranged at monitoring points at a specific distance from the concrete pouring end face, and the embedded temperature sensor 9 in the middle arranged at the center of the concrete pouring height.

[0040] This temperature monitoring module uses an embedded temperature sensor 9 as the main detection element, which is embedded in the concrete to more clearly detect the actual temperature of the concrete. The tie rod 4 serves as a structural fastener and also acts as an anchor point and positioning component for the embedded temperature sensor 9, ensuring the accurate positioning and fixation of the embedded temperature sensor 9 array in the concrete pouring cavity and ensuring the scientific nature of the measured temperature data.

[0041] In the preferred embodiment, the embedded temperature sensor 9 is connected to the vertical rib 11 through the connecting shell 15. The embedded temperature sensor 9 is set inside the sealing sleeve 1501. One end of the sealing sleeve 1501 is provided with a sealing tube 1502 for passing through and protecting the lead wire 10. A connecting buckle 1503 is provided on one side of the sealing sleeve 1501.

[0042] The sealing sleeve 1501 is made of thermally conductive material.

[0043] The sealing sleeve 1501 has good thermal conductivity, ensuring that the embedded temperature sensor 9 can quickly respond to temperature changes inside the concrete and avoid measurement delays caused by the outer shell. The sealing sleeve 1501 and the sealing tube 1502 at its upper end protect the embedded temperature sensor 9 and the lead wire 10 at its connection point, preventing the concrete from corroding the component and avoiding the impact generated during concrete pouring that could cause the embedded temperature sensor 9 to disconnect from the lead wire 10.

[0044] In the preferred embodiment, the internal circulation heating module includes heating devices 13 located on both sides of the top of the panel 1 and hot water pipes 12 connected thereto. The hot water pipes 12 are led out from one side of the heating device 13, pass around the ends of multiple aluminum beams 3 in an S-shaped path, and then connect to the other side of the heating device 13 to form a closed hot water internal circulation heating loop.

[0045] The S-shaped pipe layout can more flexibly adapt to the shape of the formwork, allowing it to cover a larger area of ​​the formwork surface. Through the continuous circulation of hot water, heat is evenly transferred to all parts of the concrete structure. The hot water internal circulation system provides continuous heating through a closed loop, resulting in high heat utilization. The S-shaped pipe only needs to be attached to the outside of the formwork, minimizing construction interference, and requires no additional treatment after removal. It is a green and healthy heating method.

[0046] In the preferred embodiment, the internal circulation heating module is connected to the intelligent temperature control module 100 through a communication unit, and the heating devices 13 on both sides are electrically connected to two communication chips 110 respectively, so as to communicate with the intelligent temperature control module 100 through the communication chips 110.

[0047] In the preferred embodiment, the communication chip 110 uses an NB-IO communication module to connect with the intelligent temperature control module 100 via data connection, so as to communicate with the host computer or host network through the intelligent temperature control module 100.

[0048] Due to its wide coverage, strong penetration and low power consumption, the NB-IoT communication module is suitable for the equipment connection needs in the complex environment of concrete construction sites. This communication method enables information exchange between the intelligent temperature control module 100 and the internal circulation heating module.

[0049] The intelligent temperature control module 100 sets an early warning value for the monitored temperature. If the temperature difference between the inside and outside of the concrete structure exceeds 22 degrees Celsius, or the average cooling rate exceeds 1.6℃ / 24h or 0.8℃ / 4h, it is determined that the temperature is abnormal during the hydration of the concrete and an alarm needs to be issued.

[0050] The intelligent temperature control module 100 acquires the temperature information of the corresponding point inside the concrete pouring, measured by the embedded temperature sensor 9, through the lead wire 10, and determines whether it exceeds the set warning value. When the warning value is exceeded, the intelligent temperature control module 100 sends heating signals to the two communication chips 110 through the NB-IoT communication module. These signals can be sent simultaneously, sequentially, or unilaterally, enabling simultaneous heating, sequential heating, or unilateral heating of the hot water pipe 12, thus achieving temperature level control of the internal circulation heating module.

[0051] Meanwhile, the intelligent temperature control module 100 communicates with the host computer or host network to send temperature monitoring data and early warning information to the user, enabling the user to remotely monitor concrete curing in real time.

[0052] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
