Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, and in particular to a prefabricated assembled concrete precast component curing system. Background Art

[0002] Prefabricated Assembled Concrete Prefab refers to concrete components prefabricated in factories or production bases, with certain size, shape and performance requirements. These prefabricated components can include various components such as wall panels, floor slabs, columns, beams, etc. They are pre-designed and manufactured, and assembled by assembly, connection and other methods during on-site construction. Prefabricated assembled concrete prefabricated components have many advantages. First, they can be precisely manufactured and quality controlled in the factory to ensure the consistency and quality of the components. Secondly, prefabricated components can be quickly installed on site, reducing construction time and labor costs. In addition, they also have high strength and durability, and can adapt to different design requirements and building structures. Prefabricated assembled concrete prefabricated components are widely used in the construction field, especially for large-scale projects and residential buildings. They bring higher efficiency, lower costs and better building quality to the construction industry.

[0003] The maintenance of precast concrete parts refers to the maintenance of proper humidity and temperature conditions to ensure the normal hardening and strength development of concrete after its manufacture, so as to promote the complete curing of concrete and the stable development of its performance. The main functions of precast concrete parts maintenance are as follows: Promote the strength development of concrete: Constant humidity and temperature conditions during the maintenance process help the full reaction of the internal moisture of concrete, promote the hydration reaction of concrete, and thus improve the strength development speed and final strength level of concrete; Control the shrinkage and cracking of concrete: In a dry environment, concrete will shrink due to the evaporation of internal moisture, which may cause cracking. Through maintenance, proper humidity can be maintained, the shrinkage behavior of concrete can be effectively controlled, the risk of cracking can be reduced, and the durability of concrete can be improved: Proper maintenance can ensure the density and stability of the internal structure of concrete, reduce the formation of pores and voids, reduce permeability, and improve the impermeability, durability and durability of concrete; Protect the quality of the concrete surface: Maintenance can avoid the drying and cracking of the concrete surface, keep the surface smooth and uniform, and improve the appearance quality and overall aesthetics.

[0004] To this end, prefabricated assembled concrete precast parts need to be placed in a curing room for curing after they are completed. However, some existing curing rooms have humidity control equipment that cannot respond to changes in the curing environment in a timely manner and cannot quickly adjust the humidity, which causes the surface of the concrete precast parts to dry out prematurely and affects the development of strength. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides a prefabricated and assembled concrete precast component maintenance system, which has the function of sending a water replenishment or drying control signal according to a reflectivity FS1 value calculated by a data analysis module. When the reflectivity FS1 value is close to 1, the data analysis module sends a water replenishment signal to the control unit. When the reflectivity FS1 value is close to -1, the data analysis module sends a drying signal to the control unit. After the control unit receives the drying model, the control unit controls the curing room to dry. After the control unit receives the water replenishment signal, the control unit controls the curing room to spray water mist for water replenishment. The concrete surface is irradiated with high-frequency electromagnetic waves, and the humidity of the current surface of the concrete precast component is calculated according to the reflected wave amplitude FS and a preset reference reflected wave amplitude CK through an algorithm formula. There is no need to physically contact the concrete surface, thereby avoiding damage and pollution to the concrete precast component, and also improving the safety and convenience of the measurement. The high-frequency reflected wave measurement can monitor the humidity change on the surface of the concrete precast component in real time, and can respond quickly, and can timely discover humidity abnormalities and obtain and send control signals. After the control unit receives the control signal, it makes adjustments in time, thereby avoiding causing the surface of the concrete precast component to dry prematurely and affecting the development of strength, and the above problems are solved.

BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 It is a schematic diagram of the system flow of the present invention. DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1 , a prefabricated and assembled concrete precast component maintenance system, comprising a concrete surface humidity measurement unit, an ambient temperature sensor, a gas collection unit, a data analysis module and a control unit, wherein the concrete surface humidity measurement unit is connected to the data analysis module via a network, the ambient temperature sensor is connected to the data analysis module via a network, the gas collection unit is connected to the data analysis module via a network, and the data analysis module is connected to the control unit via a network;

[0041] In the maintenance of precast concrete parts, it is very important to maintain appropriate humidity. For this reason, it is necessary to monitor the humidity on the surface of precast concrete parts and ensure that the humidity is within a suitable range, which is conducive to the hardening and strength development of precast concrete parts. The concrete surface humidity measurement unit uses high-frequency electromagnetic waves to irradiate the surface of precast concrete parts and measure the reflected wave amplitude FS on the surface of precast concrete parts. The concrete surface humidity measurement unit sends the collected reflected wave amplitude FS to the data analysis module. The data analysis module is preset with a reference reflected wave amplitude CK, and the reflectivity FSl of the surface of the precast concrete parts is calculated in combination with the algorithm. The reflectivity FSl algorithm formula is as follows:

[0042]

[0043] In the formula, the value range of the reflectivity FSl is calculated to be between -1 and 1. When the reflectivity FSl value is closer to 1, the surface of the precast concrete part is drier, and when the reflectivity FSl is closer to -1, the concrete surface is wetter;

[0044] The data analysis module sends a water replenishment or drying control signal according to the calculated reflectivity FS1 value. When the reflectivity FS1 value is close to 1, the data analysis module sends a water replenishment signal to the control unit. When the reflectivity FS1 value is close to -1, the data analysis module sends a drying signal to the control unit. After the control unit receives the drying model, the control unit controls the curing room to dry. After the control unit receives the water replenishment signal, the control unit controls the curing room to spray water mist for water replenishment. The concrete surface is irradiated with high-frequency electromagnetic waves, and the humidity of the current surface of the precast concrete part is calculated according to the reflected wave amplitude FS and the preset reference reflected wave amplitude CK through the algorithm formula. There is no need to physically contact the concrete surface, which avoids damage and pollution to the precast concrete parts, and also improves the safety and convenience of the measurement. The high-frequency reflected wave measurement can monitor the humidity changes on the surface of the precast concrete parts in real time, and can respond quickly, can timely detect humidity abnormalities, and obtain and send control signals. After receiving the control signal, the control unit makes timely adjustments to avoid causing the surface of the precast concrete parts to dry prematurely and affect the development of strength.

[0045] In the curing process of precast concrete, the curing temperature of concrete is very important, because temperature can affect the hardening and strength development of concrete. It is necessary to monitor the temperature in the curing room to ensure that it is within an appropriate range to promote better hardening of precast concrete. The ambient temperature sensor collects the temperature value in the curing room every 1 minute and generates WD q and WD h The ambient temperature sensor collects the temperature value WD q and WD hThe data is sent to the data analysis module through the network. The data analysis module calculates the temperature change rate WDbhl according to the algorithm formula. The temperature change rate WDbhl algorithm formula is as follows:

[0046]

[0047] In the formula, WD h is the current temperature value, WD q Indicates the temperature value of the previous minute of the current temperature value. 1 indicates that the interval between two temperature values ​​is one minute. The unit is Celsius degree / minute. The larger the result calculated by the formula, the faster the temperature changes. The smaller the result calculated by the formula, the slower the temperature changes. When the result is 0, it means constant temperature. When the temperature of the curing room reaches the preset value, the data analysis module sends a temperature increase or decrease signal according to the calculated temperature change rate WDbhl, so that the curing room is in a constant temperature state, so that the precast concrete parts are always at a suitable temperature, so that the precast concrete parts can be better hardened;

[0048] The gas composition in the curing room plays a vital role in the stable curing of precast concrete parts. For example, a typical application of carbon dioxide is the carbonation reaction in concrete, which is called carbon dioxide neutralization. Carbon dioxide neutralization refers to the process of carbon dioxide reacting with hydration products in concrete to form carbonates. This reaction helps to improve the strength and hardness of concrete; ammonia can react chemically with hydration products to generate ammonia compounds (such as calcium ammonia, aluminum ammonia, etc.), which can fill the capillary pores and microcracks of concrete and improve the surface hardness and density of concrete; oxygen is one of the necessary gases for hydration reaction, which can react with the chemical substances in cement to gradually solidify and harden it, forming the strength of concrete. At the same time, oxygen can participate in the oxidation reaction of harmful substances in concrete, such as the oxidation of iron, which helps to prevent steel corrosion and improve the durability of concrete. Therefore, it is crucial to collect the concentrations of oxygen, carbon dioxide and ammonia in the air in the curing room through gas collection units for the curing of precast concrete parts.

[0049] The collected oxygen concentration Yq is sent to the data analysis module through the network. The data analysis module calculates the oxygen concentration in the maintenance room as a percentage of the total gas content Yqnd. The data analysis module is preset with the standard value of oxygen concentration Bzy. The calculation formula for the oxygen concentration as a percentage of the total gas content Yqnd is as follows:

[0050]

[0051] In the formula, by calculating the ratio of the collected oxygen concentration Yq to the total gas Zqt, the value of the oxygen concentration in the total gas Yqnd is obtained. When the oxygen concentration in the total gas Yqnd is lower than the standard value of the oxygen concentration Bzy, the data analysis module sends an oxygen increase signal to the control unit. When the oxygen concentration in the total gas Yqnd is higher than the standard value of the oxygen concentration Bzy, the data analysis module sends a stop oxygen supply signal to the control unit.

[0052] The collected carbon dioxide concentration ey is sent to the data analysis module through the network. The data analysis module calculates the carbon dioxide concentration in the maintenance room as a percentage of the total gas eynd according to the algorithm. The data analysis module is preset with the standard value of carbon dioxide concentration Bze. The algorithm formula for the carbon dioxide concentration as a percentage of the total gas eynd is as follows:

[0053]

[0054] In the formula, the proportion of the collected carbon dioxide concentration ey to the total gas Zqt is calculated to obtain the content eynd of the carbon dioxide concentration in the total gas. When the content eynd of the carbon dioxide concentration in the total gas is lower than the standard value Bze of the carbon dioxide concentration, the control module sends a signal to increase carbon dioxide to the control unit. When the content eynd of the carbon dioxide concentration in the total gas is higher than the standard value Bze of the carbon dioxide concentration, the data analysis module sends a signal to stop increasing carbon dioxide to the control unit.

[0055] The collected ammonia concentration aq is sent to the data analysis module through the network. The data analysis module calculates the ammonia concentration as a percentage of the total gas aqnd according to the algorithm formula. The data analysis module is preset with the ammonia concentration standard value Bza. The ammonia concentration as a percentage of the total gas aqnd algorithm formula is as follows:

[0056]

[0057] In the formula, the ratio of the collected ammonia concentration aq to the total gas Zqt is calculated to obtain the content aqnd of the ammonia concentration in the total gas. When the content aqnd of the ammonia concentration in the total gas is lower than the standard value Bza of the ammonia concentration, the data analysis module will send an ammonia increase signal to the control unit. When the content aqnd of the ammonia concentration in the total gas is higher than the standard value Bza of the ammonia concentration, the data analysis module will send a signal to stop increasing ammonia to the control unit.

[0058] When the control unit receives an oxygen increase signal or an oxygen supply stop signal, the control unit controls the curing room to increase oxygen or stop oxygen supply. When the control unit receives a carbon dioxide increase signal or a carbon dioxide increase stop signal, the control unit controls the curing room to increase carbon dioxide or stop increasing carbon dioxide. When the control unit receives an ammonia increase signal or ammonia increase stop signal, the control unit controls the curing room to increase ammonia or stop increasing ammonia. By calculating the oxygen concentration in the total gas content Yqnd, the carbon dioxide concentration in the total gas content eynd and the ammonia concentration in the total gas content aqnd, the proportion of these three gases in the curing room is obtained. When any one or more gases are insufficient or exceeded, the data analysis unit sends the control limit number to the control unit, and the control unit controls the curing room to increase or decrease these gases, so that it meets the conditions for curing precast concrete parts, so that the precast concrete parts can be stably cured.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
