Description

Technical Field

[0001] The invention belongs to the field of building construction, and in particular relates to an intelligent heating and self-adaptive temperature control and regulation method for a steel formwork, which is especially applicable to winter construction operations of pouring concrete with steel formwork. Background Art

[0002] In formwork engineering, steel formwork has been widely used in concrete structure construction due to its advantages of high strength, superior integrity, high turnover efficiency, and high construction efficiency. When steel formwork is used for concrete structure pouring construction under winter construction conditions, the low ambient temperature slows down the cement hydration reaction rate, and the temperature difference between the inside and outside of the concrete is large. The concrete will have cracks, peeling, crystal corrosion, surface dusting and other diseases; the gel voids inside the concrete caused by low temperature will also greatly affect the integrity, density and durability of the concrete, which will not only affect the construction quality, but also have a great impact on the construction progress and cost. Therefore, when using steel formwork to pour concrete structure construction under winter construction conditions, taking corresponding insulation measures is an important construction process to improve the pouring quality and efficiency of concrete. When using steel formwork to pour concrete construction into winter operations, operators should usually prepare insulation materials for concrete covering, such as plastic film, colored strips, cotton felt and straw curtains, before pouring, and take corresponding anti-freeze and insulation measures. And take necessary wind-blocking and sealing measures to improve the insulation effect, or simply avoid winter construction. This method greatly increases the construction period and labor costs.

[0003] At present, domestic relevant personnel have conducted relevant research on the intelligent heating method of steel formwork. The common practice is to attach different types of heating devices to the steel formwork to increase the ambient temperature of concrete pouring and curing processes through heating, and solve the related disease problems of concrete construction in winter. However, they all conceived a mobile heating device outside the formwork alone, which is still highly dependent on manual operation and fails to meet the development trend of intelligent heating of steel formwork. Summary of the invention

[0004] The present invention aims to provide a method for intelligent heating and adaptive temperature control of steel formwork, which can achieve the purpose of intelligent heating of steel formwork during concrete structure construction in winter. The entire heating process does not require human intervention, meets the development trend of intelligent heating of steel formwork and automated temperature regulation, reduces construction costs, and effectively shortens the construction period.

The first special-shaped water tank 1 and the first special-shaped water tank 2 are both made of flexible insulating materials on the side opposite to the first iron resistor hollow ball, so that the first special-shaped water tank 1 and the second special-shaped water tank can push the first iron resistor hollow ball to move due to the expansion of liquid water inside themselves. The other side surfaces of the first special-shaped water tank 1 and the first special-shaped water tank 2 are made of insulating rigid materials.

When the temperature of the liquid water in the first special-shaped water tank 2 rises to above 4°C, the liquid water in the first special-shaped water tank 2 continues to increase in volume due to thermal expansion and cold contraction when it is above 4°C. The force exerted by the liquid water in the first special-shaped water tank 2 on the first iron resistance hollow ball exceeds the electromagnetic attraction of the first electromagnetic coil on the first iron resistance hollow ball, causing the first iron resistance hollow ball to move toward the first special-shaped water tank, touch the first switch device to disconnect the first switch device, and the first temperature control unit changes from a conductive state to an open circuit state, the first iron resistance track is disconnected, heating stops, and the first electromagnetic coil is powered off;

[0014] Step A4, when the liquid water in the first special-shaped water tank 1 and the first special-shaped water tank 2 drops below 4°C again due to the influence of air temperature, the template intelligent heating adaptive temperature control and regulation system repeats steps A2 to A3 to realize automatic temperature control of the steel template.

The side of the third special-shaped water tank opposite to the third iron resistor hollow ball is made of flexible insulating material, and the other surfaces of the third special-shaped water tank are made of insulating rigid material. The second special-shaped water tank and the third special-shaped water tank are respectively filled with liquid water. The volume of the first special-shaped water tank one is the same as that of the second special-shaped water tank, and the volume of the first special-shaped water tank two is the same as that of the third special-shaped water tank.

[0015] Preferably, in the above-mentioned steel template intelligent heating adaptive temperature control and regulation method, the method comprises the following steps:

[0016] Step B1, install the intelligent heating and adaptive temperature control and adjustment system of the template on the outer side of the steel template. In the initial state, the first switch device is in the disconnected state, the first iron resistor hollow ball is close to the first special-shaped water tank one, and the first iron resistor hollow ball is located between the first switch device and the first special-shaped water tank one; the second switch device is in the disconnected state, the second iron resistor hollow ball is detached from the second special-shaped water tank, and the second iron resistor hollow ball is located between the second switch device and the second unit anti-fall end plate; the third switch device is in the disconnected state, the third iron resistor hollow ball is detached from the third special-shaped water tank, and the third iron resistor hollow ball is located between the third switch device and the third unit anti-fall end plate.

[0017] Step B2, when the temperature drops to 4°C, the volume of the liquid water in the first special-shaped water tank 1 is the smallest when the temperature drops to 4°C. As the temperature continues to drop, the liquid water in the first special-shaped water tank 1 increases in volume due to cold expansion and heat contraction at 0~4°C, squeezing the first iron resistor hollow ball to move along the first iron resistor track toward the first special-shaped water tank 2, touching the first switch device, so that the first switch device is closed, the first temperature control unit changes from an open circuit state to a conductive state, the first iron resistor track is energized to start heating, the first electromagnetic coil is energized to generate magnetic force, further attracting the first iron resistor hollow ball to move along the first iron resistor track toward the first special-shaped water tank 2 until it fits with the first special-shaped water tank 2 and stops. At this point, the intelligent heating adaptive temperature control and adjustment device is started, and the first temperature control unit starts heating;

[0018] Step B3, the magnetic force generated by the first electromagnetic coil of the first temperature control unit attracts the first hollow iron resistor ball to move in the second direction of the first special-shaped water tank, and at the same time attracts the second hollow iron resistor ball to move in the direction of the second special-shaped water tank, until the second hollow iron resistor ball fits with the second special-shaped water tank, and the second hollow iron resistor ball touches the second switch device during the movement of the second hollow iron resistor ball in the direction of the second special-shaped water tank, so that the second switch device is closed, and the second temperature control unit changes from the open circuit state to the conductive state, and the second iron resistor track is energized to start heating, and the second electromagnetic coil is energized to generate magnetic force, and the electromagnetic attraction of the second electromagnetic coil to the second hollow iron resistor ball is offset by the electromagnetic attraction of the first electromagnetic coil to the second hollow iron resistor ball, and the second hollow iron resistor ball is stationary and fits with the second special-shaped water tank;

[0019] Step B4, after the second electromagnetic coil is energized, the second iron resistor hollow ball is attracted to move toward the anti-fall end plate of the second temperature control unit, and the third iron resistor hollow ball is attracted to move toward the third special-shaped water tank until the third iron resistor hollow ball fits the third special-shaped water tank. During the movement of the third iron resistor hollow ball toward the third special-shaped water tank, the third iron resistor hollow ball closes the third switch device, and the third temperature control unit changes from an open circuit state to a conductive state. The third iron resistor track is energized to start heating, so that the entire steel template intelligent heating adaptive temperature control and adjustment device reaches a fully working state;

[0020] Step B5, as the first iron resistance track, the second iron resistance track and the third iron resistance track are continuously heated, the temperature of the liquid water in the first special-shaped water tank 2 and the third special-shaped water tank rises back to above 4°C. When the liquid water in the first special-shaped water tank 2 and the third special-shaped water tank is above 4°C, the volume continues to increase due to thermal expansion and contraction. The force of the liquid water in the first special-shaped water tank 2 on the first iron resistance hollow ball increases and exceeds the sum of the electromagnetic attraction of the first electromagnetic coil and the second electromagnetic coil on the first iron resistance hollow ball. The first iron resistance hollow ball moves toward the first special-shaped water tank 2, so that the first switch device is disconnected, and the first iron resistance track is disconnected to stop heating; the force of the liquid water in the third special-shaped water tank on the third iron resistance hollow ball increases and exceeds the sum of the electromagnetic attraction of the first electromagnetic coil and the second electromagnetic coil on the third iron resistance hollow ball. The third iron resistance hollow ball moves toward the anti-fall end plate of the third temperature control unit, so that the third switch device is disconnected, and the third iron resistance track is disconnected to stop heating, thereby achieving the effect of primary temperature control;

[0021] Step B6, as the second iron resistance track continues to heat, the temperature of the liquid water in the second special-shaped water tank continues to rise above 4°C, and the liquid water in the second special-shaped water tank continues to increase in volume due to thermal expansion and contraction above 4°C. The force of the liquid water in the second special-shaped water tank on the second iron resistance hollow ball continues to increase and exceeds the electromagnetic attraction of the second electromagnetic coil to the second iron resistance hollow ball. The second iron resistance hollow ball moves toward the anti-fall end plate of the second temperature control unit, so that the second switch device is disconnected, the second iron resistance track is disconnected, the heating is stopped, and the second electromagnetic coil is powered off, thereby achieving the effect of secondary temperature control;

[0022] Step B7, when the liquid water in the first special-shaped water tank drops below 4°C again due to the influence of air temperature, the template intelligent heating adaptive temperature control and regulation system repeats steps B2 to B6 to achieve automatic graded temperature control of the steel template.

[0023] Preferably, in the above-mentioned steel formwork intelligent heating adaptive temperature control and adjustment method, the first switch device, the second switch device and the third switch device each include a cross-rotating switch and two telescopic conductive ports, the two telescopic conductive ports are arranged on both sides of the cross-rotating switch, the cross-rotating switch includes a conductive electrode and an insulating pole arranged perpendicular to each other, and the cross-rotating switch rotates 90 degrees to realize the switching between the two telescopic conductive ports being connected through the conductive electrode and being connected through the insulating pole. In the initial state, the insulating poles in the cross-rotating switches of the first switch device, the second switch device and the third switch device are respectively connected to the telescopic conductive ports on both sides.

[0043] Preferably, in the above-mentioned steel formwork intelligent heating adaptive temperature control adjustment method, the first special-shaped water tank 14 and the first special-shaped water tank 2 15 are respectively filled with liquid water in the same proportion of their own volume.

[0045] Preferably, in the above-mentioned steel template intelligent heating adaptive temperature control and regulation method, the method comprises the following steps:

[0046] Step A1, install the template intelligent heating adaptive temperature control and regulation system on the outer surface of the steel template. In the initial state, the first switch device 12 is in the disconnected state, the first iron resistor hollow ball 13 is close to the first special-shaped water tank 14, and the first iron resistor hollow ball 13 is located between the first switch device 12 and the first special-shaped water tank 14, specifically, the first iron resistor hollow ball 13 is located between the cross rotary switch 51 of the first switch device 12 and the first special-shaped water tank 14, that is, the first iron resistor hollow ball 13 is located on the left side of the first switch device 12, such as Figure 2 shown.

[0047] Step A2, when the temperature drops to 4°C, the temperature of the liquid water in the first special-shaped water tank 14 drops to the minimum volume at 4°C. As the temperature continues to drop, the liquid water in the first special-shaped water tank 1 increases in volume due to thermal expansion and contraction at 0-4°C, squeezing the first iron resistor hollow ball 13 to move along the first iron resistor track 11 toward the first special-shaped water tank 2 15, i.e., to the right, so that the first switch device 12 is closed, and the first temperature control unit 1 is changed from the open circuit state to the conductive state. The first iron resistor track 11 starts to heat after being energized, and the first electromagnetic coil 16 generates magnetic force after being energized, further attracting the first iron resistor hollow ball 13 to move along the first iron resistor track 11 toward the first special-shaped water tank 2 15 until it is in contact with the first special-shaped water tank 2 15 and then stops. Figure 4 shown.

[0048] Step A3, as the first iron resistance track 11 is continuously heated, the liquid water in the first special-shaped water tank 15 gradually decreases in volume due to thermal expansion and contraction during the process of rising from below 4°C to 4°C, and returns to the initial state size. When the temperature of the liquid water in the first special-shaped water tank 15 rises to above 4°C, the liquid water in the first special-shaped water tank 15 continues to increase in volume due to thermal expansion and contraction when it is above 4°C. The force of the liquid water in the first special-shaped water tank 15 on the first iron resistance hollow ball 13 exceeds the electromagnetic attraction of the first electromagnetic coil 16 on the first iron resistance hollow ball 13, causing the first iron resistance hollow ball 13 to move toward the first special-shaped water tank 14, i.e., to the left, and touch the first switch device 12 to disconnect the first switch device 12, and the first temperature control unit 1 changes from a conductive state to an open circuit state, the first iron resistance track 11 is disconnected, heating stops, and the first electromagnetic coil 16 is powered off. Figure 5 In this embodiment, the electromagnetic attraction of the first electromagnetic coil 16 to the first iron resistor hollow ball 13 can be set to be smaller than the force exerted by the liquid water in the first special-shaped water tank 15 at 5-6°C on the first iron resistor hollow ball 13, so that the temperature of the steel template is roughly controlled between 3-6°C.

[0049] Step A4, when the liquid water in the first special-shaped water tank 14 drops below 4°C again due to the influence of air temperature, the template intelligent heating and adaptive temperature control and regulation system repeats steps A2 to A3 to realize automatic temperature control of the steel template 6. That is to say, the template intelligent heating and adaptive temperature control and regulation system can intelligently heat the steel template 6 according to changes in air temperature. The entire heating process does not require human intervention, which meets the requirements of intelligent heating and automated temperature regulation of the steel template 6, effectively reduces construction costs, and shortens construction periods.

[0053] Preferably, in the above-mentioned steel formwork intelligent heating adaptive temperature control and regulation method, the second special-shaped water tank 24 and the third special-shaped water tank 34 are respectively filled with liquid water in the same proportion of their own volume. Specifically, in the present application, the second special-shaped water tank 24 and the third special-shaped water tank 34 are respectively filled with liquid water of 1 / 2 to 2 / 3 of their own volume to prevent the second special-shaped water tank 24 and the third special-shaped water tank 34 from rupture due to the expansion of the internal liquid water.

[0054] Preferably, in the above-mentioned steel template intelligent heating adaptive temperature control and regulation method, the method comprises the following steps:

[0055] Step B1, install the template intelligent heating adaptive temperature control system on the outer surface of the steel template 6, in the initial state, such as Figure 6As shown, the first switch device 12 is in the disconnected state, the first iron resistor hollow ball 13 is close to the first special-shaped water tank 14, and the first iron resistor hollow ball 13 is located between the first switch device 12 and the first special-shaped water tank 14, specifically, the first iron resistor hollow ball 13 is located between the cross rotary switch 51 of the first switch device 12 and the first special-shaped water tank 14, that is, the first iron resistor hollow ball 13 is located on the left side of the cross rotary switch 51 of the first switch device 12; the second switch device 22 is in the disconnected state, the second iron resistor hollow ball 23 is separated from the second special-shaped water tank 24, and the second iron resistor hollow ball 23 is located between the second switch device 22 and the second unit anti-fall end plate, specifically The second iron resistor hollow ball 23 is located between the cross rotary switch 51 of the second switch device 22 and the second unit anti-fall end plate one, that is, the second iron resistor hollow ball 23 is located on the right side of the cross rotary switch 51 of the second switch device 22; the third switch device 32 is in the disconnected state, the third iron resistor hollow ball 33 is detached from the third special-shaped water tank 34, and the third iron resistor hollow ball 33 is located between the third switch device 32 and the third unit anti-fall end plate, specifically, the third iron resistor hollow ball 33 is located between the cross rotary switch 51 of the third switch device 32 and the third unit anti-fall end plate one, that is, the third iron resistor hollow ball 33 is located on the right side of the cross rotary switch 51 of the third switch device 32.

[0056] Step B2, when the temperature drops to 4°C, the temperature of the liquid water in the first special-shaped water tank 1 drops to the minimum volume at 4°C. As the temperature continues to drop, since only the inner side of the first special-shaped water tank 14 that contacts the iron resistor hollow ball is a flexible material, the liquid water in the first special-shaped water tank 14 increases in volume due to cold expansion and heat contraction at 0~4°C, squeezing the first iron resistor hollow ball 13 to move to the right along the first iron resistor track 11, touching the first switch device 12, so that the first switch device 12 is closed, and the first temperature control unit 1 changes from an open circuit state to a conductive state, and the first iron resistor track 11 is energized to start heating, and the first electromagnetic coil 16 is energized to generate magnetic force, which further attracts the first iron resistor hollow ball 13 to move along the first iron resistor track 11 toward the first special-shaped water tank 2 15, that is, to the right until it is in contact with the first special-shaped water tank 2 15 and then stops. At this point, the intelligent heating adaptive temperature control regulating device 100 is started, and the first temperature control unit 1 starts heating. Figure 7 shown.

[0057] Step B3, the magnetic force generated by the first electromagnetic coil 16 of the first temperature control unit 1 attracts the first iron resistor hollow ball 13 to move toward the first special-shaped water tank 15, that is, to the right, and at the same time attracts the second iron resistor hollow ball 23 to move toward the second special-shaped water tank 24, that is, to the left, until the second iron resistor hollow ball 23 fits with the second special-shaped water tank 24. During the movement of the second iron resistor hollow ball 23 toward the second special-shaped water tank 24, it touches the second switch device 22, so that the second switch device 22 is closed, and the second temperature control unit 2 changes from the open circuit state to the conductive state, and the second iron resistor track 21 is energized to start heating, and the second electromagnetic coil 26 is energized to generate magnetic force. The electromagnetic attraction of the second electromagnetic coil 26 to the second iron resistor hollow ball 23 is offset by the electromagnetic attraction of the first electromagnetic coil 16 to the second iron resistor hollow ball 23, and the second iron resistor hollow ball 23 is stationary and fits with the second special-shaped water tank 24. Figure 8 shown.

[0058] Step B4, after the second electromagnetic coil 26 is energized, it attracts the second iron resistor hollow ball 23 to move to the right, and at the same time attracts the third iron resistor hollow ball 33 to move to the third special-shaped water tank 34, that is, to the left, until the third iron resistor hollow ball 33 fits the third special-shaped water tank 34. During the movement of the third iron resistor hollow ball 33 to the third special-shaped water tank 34, the third iron resistor hollow ball 33 closes the third switch device 32, and the third temperature control unit 3 changes from the open circuit state to the conductive state. The third iron resistor track 31 is energized to start heating, so that the entire steel template intelligent heating adaptive temperature control and regulation device 100 reaches a fully working state, such as Fig. 9 shown.

[0059] Step B5, as the first iron resistance track 11, the second iron resistance track 21 and the third iron resistance track 21 are continuously heated, the temperature of the liquid water in the first special-shaped water tank 15 and the third special-shaped water tank 34 rises back to above 4°C. When the temperature of the liquid water in the first special-shaped water tank 15 and the third special-shaped water tank 34 is above 4°C, the volume of the liquid water in the first special-shaped water tank 15 and the third special-shaped water tank 34 continues to increase due to thermal expansion and contraction. The force exerted by the liquid water in the first special-shaped water tank 15 on the first iron resistance hollow ball 13 increases and exceeds the sum of the electromagnetic attraction of the first electromagnetic coil 16 and the second electromagnetic coil 26 on the first iron resistance hollow ball 13. The iron resistor hollow ball 13 moves toward the first special-shaped water tank 15, so that the first switch device 12 is disconnected, and the first iron resistor track 11 is disconnected and stops heating; the force of the liquid water in the third special-shaped water tank 34 on the third iron resistor hollow ball 33 increases and exceeds the sum of the electromagnetic attraction of the first electromagnetic coil 16 and the second electromagnetic coil 26 on the third iron resistor hollow ball 33, and the third iron resistor hollow ball 33 moves toward the third temperature control unit anti-fall end plate 35, so that the third switch device 32 is disconnected, and the third iron resistor track 31 is disconnected and stops heating, thereby achieving the effect of primary temperature control, such as Fig.10 In this embodiment, the sum of the electromagnetic attraction of the first electromagnetic coil 16 and the second electromagnetic coil 26 to the first iron resistor hollow ball 13 can be set to be smaller than the force exerted by the liquid water in the first special-shaped water tank 15 on the first iron resistor hollow ball 13 at 5-6°C, and the sum of the electromagnetic attraction of the first electromagnetic coil 16 and the second electromagnetic coil 26 to the third iron resistor hollow ball can be set to be smaller than the force exerted by the liquid water in the third special-shaped water tank 34 on the third iron resistor hollow ball 33 at 5-6°C.

[0060] Step B6, as the second iron resistance track 21 continues to heat, the temperature of the liquid water in the second special-shaped water tank 24 continues to rise above 4°C, and the liquid water in the second special-shaped water tank 24 continues to increase in volume due to thermal expansion and contraction above 4°C. The force of the liquid water in the second special-shaped water tank 24 on the second iron resistor hollow ball 23 continues to increase and exceeds the electromagnetic attraction of the second electromagnetic coil 26 on the second iron resistor hollow ball 23. The second iron resistor hollow ball 23 moves toward the anti-fall end plate 25 of the second temperature control unit, so that the second switch device 22 is disconnected, the second iron resistor track 21 is disconnected, the heating is stopped, and the second electromagnetic coil 26 is powered off, thereby achieving the effect of secondary temperature control, such as Fig.11 In this embodiment, the electromagnetic attraction of the second electromagnetic coil 26 to the second iron resistor hollow ball 23 can be set to be smaller than the force exerted by the liquid water in the second special-shaped water tank 24 on the second iron resistor hollow ball 23 at 6-7°C. Thus, the temperature of the steel template can be roughly controlled between 3-7°C.

[0061] Step B7, when the liquid water in the first special-shaped water tank 14 drops below 4°C again due to the influence of air temperature, the template intelligent heating adaptive temperature control and regulation system repeats steps B2 to B6 to achieve automatic graded temperature control of the steel template 6.

[0062] From the above, it can be seen that the intelligent heating and adaptive temperature control method of steel formwork provided by the present invention can not only achieve the purpose of intelligent heating of steel formwork during winter concrete structure construction, but also automatically adjust the heating temperature level according to the change of ambient temperature of the steel formwork 6, so as to realize more precise temperature control of the steel formwork 6. Under the premise of ensuring the quality of winter concrete construction, it effectively reduces the energy consumption caused by heating. The entire heating process does not require human intervention, which meets the development trend of intelligent heating of steel formwork 6 and automatic temperature adjustment, reduces construction costs, and effectively shortens the construction period.
