Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically to a novel composite building formwork. Background Technology

[0002] Concrete formwork refers to the formwork used to shape freshly poured concrete and the entire structural system supporting the formwork. There are various classification methods for formwork, including two types according to shape: flat formwork and curved formwork; and two types according to stress conditions: load-bearing formwork and non-load-bearing formwork.

[0003] Currently, concrete formwork mainly uses steel, aluminum, and wood formwork. Formwork used in building construction requires specific treatment in northern winters. Additionally, the construction of concrete chimneys for thermal power plants commonly uses metal formwork, as the concrete curing requirements are high, also facing challenges in winter construction. Wind turbine towers have a simple concrete structure, but concrete curing during construction is a crucial issue, significantly restricting the construction cycle. In the cold winters of northern my country, the quality of the concrete is paramount; insufficient temperature compromises quality, leading to increased formwork and labor costs. Open-flame heating is difficult to control manually, causes environmental pollution, and poses safety hazards. Electric blankets for heating and insulation increase labor costs, are difficult to control manually, and also present certain safety risks.

[0004] Despite the different winter construction methods used, controlling the winter curing temperature of concrete is an urgent problem to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a temperature-controllable composite template. The heating system can automatically adjust the template temperature according to the real-time temperature, thereby promoting the concrete to solidify within the specified temperature range.

[0006] To achieve the above objectives, this utility model provides the following technical solution, mainly including:

[0007] A new type of composite building formwork, comprising:

[0008] Composite formwork, which is designed according to the shape of the building casting, including but not limited to flat panels and curved panels, is made of materials with a thermal conductivity greater than 16 W / (m·K) and is used to enclose the casting body by a number of composite formwork pieces; a single composite formwork includes at least one structural layer formwork and one insulation layer;

[0009] Thermal insulation layer: A thermal insulation layer is provided on the outer layer of the structural layer template;

[0010] A temperature control system is provided between the structural layer template and the insulation layer. The temperature control system includes a heating element, a temperature sensor, and a temperature control module. The heating element heats the composite template, and the composite template conducts the heat to the casting body. The temperature control module is used for regulation.

[0011] In one specific embodiment, the structural layer template is made of metal and is arranged in a plate-like structure, along the flat surface of the casting body.

[0012] In one specific embodiment, the metallic material includes, but is not limited to, iron, aluminum, copper, and alloy materials.

[0013] In one specific embodiment, the insulation layer is a composite material insulation layer, which is bonded to the structural layer template by an adhesive or detachably connected to the structural layer template by a snap-fit ​​mechanism.

[0014] In one specific embodiment, the composite material insulation layer is one of the following: polyurethane composite board, extruded polystyrene composite board, glass wool composite board, phenolic composite board, polystyrene particle insulation mortar, or calcium silicate board composite material.

[0015] In one specific embodiment, the temperature control system includes a power supply, a control panel, a temperature sensor, and a heating element. The power supply provides power to the temperature control system and includes a leakage current protector in the circuit. The power supply provides power to the control panel, which adjusts the temperature through the temperature control module. The temperature sensor transmits the temperature signal to the control panel.

[0016] In one specific embodiment, the heating element is a heating resistance wire, which is uniformly laid according to the composite template. The laying method includes, but is not limited to, a U-shaped ring laying method.

[0017] In one specific embodiment, the temperature control module adopts a PID control algorithm, a digital switch controls the opening and closing of the heating element, and the temperature sensor that transmits signals to the temperature control module is a DS18B20 digital temperature sensor.

[0018] As can be seen from the above technical solution, compared with the prior art, this utility model has the following beneficial effects:

[0019] The beneficial effects of this new composite building formwork are reflected in its structure, material selection, and temperature control design, and it has the following significant advantages:

[0020] 1. Highly efficient thermal conductivity:

[0021] Structural materials with a thermal conductivity greater than 16 W / (m·K) are used, such as iron, aluminum, and copper. These metal materials have high thermal conductivity and can quickly and effectively transfer heat to the casting body when the temperature control system is heating.

[0022] Heat conduction to the casting body can accelerate the curing process of concrete in low-temperature environments, shorten the construction cycle, and is especially suitable for maintaining stable casting quality during low-temperature or winter construction.

[0023] 2. Temperature control system ensures pouring quality:

[0024] The temperature control system, including heating elements, temperature sensors, and a temperature control module, is designed to precisely regulate the temperature of the template. Heating via resistance wires ensures controllable temperature of the composite template, helping to maintain a stable temperature during concrete pouring and curing.

[0025] The use of PID control algorithm enables the temperature control system to have better accuracy and response speed in temperature regulation, avoiding overheating or excessive temperature fluctuations, thereby ensuring uniform curing of concrete and improving the quality of pouring.

[0026] The temperature sensor (DS18B20) monitors temperature changes in real time and feeds the feedback to the temperature control module, enabling the temperature control system to adjust the temperature in a timely manner, reduce temperature fluctuations, and ensure that the temperature of the cast body is within the optimal range, thereby reducing the occurrence of cracks and structural defects.

[0027] 3. Energy saving and heat preservation effect:

[0028] The installation of the insulation layer can significantly reduce heat loss, maintain the temperature during the heating process, allow more heat to be applied to the main body of the casting, improve the efficiency of heat energy utilization, and reduce energy consumption.

[0029] Because of the use of composite material insulation layers (such as polyurethane composite boards, rock wool composite boards, extruded polystyrene composite boards, etc.), these materials have excellent thermal insulation performance and can effectively isolate the influence of external ambient temperature, especially in winter or low-temperature construction environments, which can significantly improve construction conditions.

[0030] 4. Improve construction efficiency and shorten the construction period:

[0031] Constant temperature pouring conditions can significantly accelerate the curing of concrete. Normally, concrete curing is delayed in low-temperature environments. By controlling the temperature of the composite formwork, the poured body is kept within a favorable temperature range, thereby accelerating the curing speed and shortening the construction cycle.

[0032] The combination of power supply and control panel makes the temperature control system easy to operate with a visual interface. It can quickly adjust the heating intensity according to the needs of the site, realize automated temperature control, and greatly reduce the workload of manual adjustment.

[0033] 5. Construction safety and system reliability:

[0034] The design of the residual current device (RCD) adds an extra layer of safety to the temperature control system, effectively preventing the danger of leakage caused by circuit faults during on-site construction and ensuring the safety of construction personnel.

[0035] Evenly laying heating resistance wires can avoid local overheating or uneven heat distribution, providing a uniform heating effect, which helps maintain the overall performance of concrete and improves molding quality.

[0036] 6. Modular design, easy to use and disassemble:

[0037] Using composite formwork in various forms, such as flat panels and curved panels, it can be flexibly combined according to the actual needs of building pouring, adapting to different construction requirements. Meanwhile, the structural layer formwork and insulation layer are detachable, and the entire system is a composite formwork, prefabricated into modules, effectively reducing on-site construction time.

[0038] The U-shaped laying method of heating resistance wire is easy to install and disassemble, and also facilitates maintenance and adjustment during construction, reducing the risk of downtime caused by temperature control system failure.

[0039] 7. Suitable for various environments and has stable performance:

[0040] This formwork system can adapt to different environmental and climatic conditions, and has significant advantages, especially in special climates such as low temperature and high humidity. Through the combination of heating system and insulation layer, the formwork can maintain a stable temperature in different construction environments, ensuring the smooth progress of concrete construction.

Detailed Implementation

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Example 1: Winter Low Temperature Concrete Pouring Construction

[0047] In cold northern regions, during winter concrete pouring, the ambient temperature may be lower than the standard curing temperature of concrete, severely affecting its setting and strength. In this embodiment, a novel composite formwork is used to ensure that the concrete temperature remains within a suitable range during construction, avoiding construction quality problems caused by excessively low temperatures.

[0048] The template includes a structural layer template, a composite material insulation layer, and a temperature control system. Specifically, the structural layer template is made of aluminum sheet with a thermal conductivity of 237 W / (m·K), exhibiting excellent thermal conductivity. The structural layer template is designed according to the shape of the building pour, including but not limited to flat or curved panels, flexibly adapting to different pouring requirements. The insulation layer uses composite insulation material, firmly bonded to the outside of the composite template with adhesive, providing thermal insulation and preventing heat loss.

[0049] The temperature control system includes heating resistance wires laid inside the composite formwork, a temperature sensor (DS18B20), and a control module. A power supply is connected at the construction site to provide power to the control panel and heating resistance wires. During pouring, the temperature sensor monitors the temperature change between the formwork and the concrete in real time. When the temperature drops below the set concrete curing temperature, the temperature control module automatically activates the heating resistance wires using a PID algorithm, heating the composite formwork. This allows heat to be transferred through the highly thermally conductive formwork to the concrete pour, ensuring that the concrete can still complete its curing process even at low temperatures. High density curing .

[0050] During construction, the temperature control system ensured that the concrete remained within the standard curing temperature range, accelerating the curing process. A residual current device (RCD) also ensured safety during construction, preventing risks associated with electrical equipment malfunctions in humid environments.

[0051] Example 2: Construction of Exterior Walls for High-Rise Buildings

[0052] In the construction of exterior walls for high-rise buildings, the temperature of the poured concrete is prone to fluctuations due to the influence of ambient temperature and wind speed, affecting the quality and strength of the exterior wall. In this embodiment, a novel composite building formwork is used to ensure the temperature stability of the poured concrete, thereby improving construction quality.

[0053] The structural formwork is made of iron, in a plate-like structure, and laid flat along the exterior walls of the high-rise building. Iron has high thermal conductivity (approximately 16-25 W / (m·K)), effectively transferring heat to the concrete. The insulation layer uses polyurethane composite panels, which are tightly bonded to the composite formwork with a high-efficiency adhesive to ensure excellent insulation performance.

[0054] The temperature control system features evenly laid heating resistance wires in a U-shaped loop, covering the entire inner side of the formwork. These heating resistance wires are connected to the temperature control module and control panel, with a power supply providing stable electrical support. A DS18B20 temperature sensor collects the formwork temperature in real time and feeds it back to the control panel. The temperature control module adjusts the temperature using a PID control algorithm to maintain the temperature of the external wall formwork and the cast-in-place concrete at approximately the standard curing temperature.

[0055] This temperature control measure ensures that the concrete pouring for the exterior walls maintains a stable curing environment even under conditions of high wind speeds or large diurnal temperature variations, preventing surface cracks caused by drastic fluctuations in ambient temperature. The application of an insulation layer effectively retains the heat generated during heating, reducing energy consumption.

[0056] Example 3: Thermal Insulation Pouring Construction of High-Rise Buildings

[0057] In the pouring construction of high-rise buildings, the high humidity and low temperature of the construction environment fall below the temperature range required for concrete curing. Therefore, it is necessary to ensure a suitable temperature environment during the pouring process. In this embodiment, a novel composite building formwork is used to achieve both insulation and heating during the construction process.

[0058] The structural layer formwork uses iron plates, the thickness of which is determined according to the construction site conditions. It is flat and laid on both sides of the high-rise building's cast-in-place structure to ensure the formwork can support the weight of the structure and provide sufficient strength. Composite formwork can be configured in different shapes, such as curved panels, to adapt to the structural characteristics of high-rise buildings. The insulation layer uses glass wool composite panels. These panels, along with the temperature control system, are detachably connected to the structural layer formwork for easy disassembly. They offer excellent insulation and moisture absorption, effectively isolating the formwork from external moisture.

[0059] The temperature control system includes a heating resistance wire and a temperature control module. A power supply provides power to the entire system. The heating resistance wire is laid between the iron plate and the glass wool composite board, and a PID control algorithm is used to adjust the heating power. A temperature sensor monitors the template temperature in real time and provides feedback through the control panel, ensuring that the temperature control module can quickly adjust when the temperature deviates from the set value.

[0060] In this embodiment, the temperature is controlled by a temperature control module, which ensures that the cast-in-place material is cured within the standard curing temperature range, preventing concrete quality problems caused by high humidity in the high-altitude environment and guaranteeing the strength and durability of the concrete.

[0061] The construction process of this template:

[0062] The new composite formwork can be used for concrete components;

[0063] S1. Apply a release agent to the inside of the template before use to facilitate disassembly after solidification.

[0064] S2. After the reinforcing bars are tied, install the formwork correctly and reinforce it.

[0065] S3. After the template is installed, select whether to preheat based on the external environment and set the temperature.

[0066] S4. After automatically detecting that the set temperature has been reached, pouring begins, accompanied by vibration to ensure that air bubbles are expelled.

[0067] S5. After pouring is complete, the upper sealing plate is closed to form a sealed space. At the same time, the upper sealing plate is powered on for heating and insulation.

[0068] S6. Automatic temperature control; once the standard is reached, the mold is removed and the template is cleaned.

[0069] In summary, the main advantage of this utility model is that after the template is assembled, the heating system can be started to preheat the template. Once the temperature reaches the required level, the concrete pouring begins. Throughout the pouring process, the concrete temperature is maintained within the required range through heat conduction, effectively ensuring the curing quality of the concrete.

[0070] Regulatory advantages

[0071] Concrete construction in winter, especially in northern regions, is subject to extremely strict quality control due to temperature fluctuations. By employing this formwork system, ordinary concrete construction can achieve real-time temperature monitoring and control, maintaining the temperature within a suitable range throughout the concrete's setting time.

[0072] Construction advantages

[0073] This new type of composite formwork performs excellently during construction. Its unique structure achieves the characteristics of being lightweight, high-strength, compact, and easy to transport. The metal structural layer is made of alloy material, which has high strength and can completely replace traditional large steel formwork. At the same time, the composite material insulation layer not only achieves thermal insulation but also enhances the strength of the metal structural layer to a certain extent. In addition, no additional processing is required during construction and installation, which greatly reduces construction costs and effectively ensures quality.

[0074] Scale control

[0075] Traditionally, winter concrete construction requires additional external measures, such as adding fencing and internal heating, all of which necessitate on-site equipment and materials. This significantly increases construction and economic costs, and the uncontrollable and unmonitorable temperature poses safety hazards. This new type of formwork, however, integrates the heating and insulation system within the formwork itself, fully meeting winter construction requirements without the need for external equipment. This also standardizes on-site management, improves efficiency, and reduces costs.
