Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more specifically, it relates to a concrete moisture preservation and curing device for building construction and its construction method. Background Technique

[0002] Concrete curing is to artificially create certain humidity and temperature conditions to enable the freshly poured concrete to harden normally or accelerate its hardening and strength growth. Concrete curing methods include natural curing, that is, by taking measures such as wrapping with formwork, watering, spraying water, etc. for moisture preservation and humid curing to ensure that the formwork joints do not lose water and dry out. It is also possible to use curing liquid for curing. Spray the perchloroethylene resin solution on the concrete surface with a spray gun. After the solution volatilizes, a plastic film is formed on the concrete surface, isolating the concrete from the air and preventing the evaporation of water in it to ensure the normal progress of the hydration reaction.

[0003] Existing moisture preservation and curing usually use manual methods, which have a large labor intensity. Especially in hot weather, it may cause workers to suffer from heat stroke, and there is also the situation of uneven spraying, resulting in poor curing effect of concrete and possibly causing problems such as cracks in the concrete. In view of the above problems, a concrete moisture preservation and curing device for building construction is disclosed in the prior art, with the patent number 202310199627.3. It mainly sets a transmission component, a sealing component, a water pipe and a shunt pipe. Through the movement of the moving table, the roller rotates the fixed shaft, and then through the first transmission component, the rotating rod drives the shunt pipe to rotate through the connecting rod. The water pipe pumps water from the inside of the water tank, and the sealing component prevents water leakage and prevents the water pipe from being wound due to rotation. Then, the water is shunted into the inside of the drainage pipe through the shunt pipe and sprayed out through the adjustable nozzle, achieving the effect of being able to move and automatically spray water at the same time, and being able to rotate and spray without using additional power, saving energy and spraying evenly, solving the problems that existing moisture preservation and curing usually use manual methods, with a large labor intensity, especially in hot weather, it may cause workers to suffer from heat stroke, and there is also the situation of uneven spraying, resulting in poor curing effect of concrete and possibly causing problems such as cracks in the concrete.

[0004] However, we still find that the above method cannot effectively solve the problems of improving the moisture preservation efficiency, the sustainability of moisture preservation, and the stable control of water pressure. Therefore, based on the above problems, the present invention obtains a concrete moisture preservation and curing device for building construction that can improve the moisture preservation efficiency and the moisture preservation continuous effect. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a concrete moisture preservation and curing device for building construction that can improve the moisture preservation efficiency and the moisture preservation continuous effect.

[0006] To achieve the above object, the present invention provides the following technical solutions: A concrete moisture conservation device for building construction, including a movable mounting frame, and further including a plurality of mounting plates arranged on the movable mounting frame, a first shielding plate and a second shielding plate arranged on each of the mounting plates.

[0012] A moisturizing method for the concrete moisturizing and curing device for building construction applicable to the above, the concrete moisturizing method specifically includes the following steps: S1. Construct a concrete foundation: Install movable mounting frames for installing water-locking and moisturizing devices around the area where concrete moisturizing is required; the distance between the movable mounting frame and the edge of the moisturizing area is L, and L is between 50 - 100 cm.

[0013] S2. Install mounting plates: Install vertical mounting plates on the movable mounting frames distributed on the peripheral side of the concrete foundation pit constructed in S1; fixing plates for fixing the movable mounting frames are also provided on the peripheral side of the concrete foundation pit.

[0014] S3. Fix the mounting plates: Tilt and fix the mounting plates on the movable mounting frames from the vertical position towards the side of the concrete base pit to form an inclined plane, and the inclination angle of the inclined plane is K, where 0° ≤ K ≤ 30°; preliminarily fix the mounting plates.

[0015] S4. Install the first shielding plate: Install the first shielding plate on the mounting plates installed in S3; the first shielding plate is installed at the position fitting the inclined plane of the mounting plate, and a number of first shielding plates are installed in parallel on both sides of the mounting plate, and the length of the first shielding plate increases successively from bottom to top in the concrete foundation pit.

[0016] S5. Install the second shielding plate: Install the second shielding plate between the mounting plates in S2; the height of the mounting plate is greater than the depth of the concrete foundation pit plus the depth of the pit; the second shielding plate after installation is arc-shaped, and the distance between the middle of the second shielding plate and the ground is less than the distance between both ends and the ground;

[0017] A number of ventilation holes are provided on the second shielding plate, a steam collection chamber is arranged on the lower surface of the second shielding plate below the ventilation holes, the cross-section of the steam collection chamber is trapezoidal, a through hole is provided in the middle of the steam collection chamber, and the steam collection chamber is distributed to collect dew when there is dew at night and inject the dew into the concrete through the through hole;

[0018] A number of water collection grooves are provided on the lower surface of the second shielding plate, and the water collection grooves are designed as inverted trapezoids;

[0019] A drip groove is arranged on the water collection groove at the center of the lower surface of the second shielding plate, and the cross-section of the drip groove is designed as a rectangle;

[0020] S6. Install humidity sensors in the concrete foundation pit: Install concrete humidity sensors around the moisturizing area to detect the humidity of the concrete.

[0021] S7. Analyze the detected data: Transmit the concrete humidity data detected in S6 to the control center, and analyze through the control center to form a curve of the change of the concrete humidity data.

[0022] By adopting the above technical solution, the beneficial effects are as follows: 1. In the present invention, a movable mounting frame is arranged in the concrete area that needs to be moisturized, a plate is installed on the movable mounting frame, and spray heads, as well as first and second shielding plates, are arranged on the plate. This realizes spray moisturization in the concrete moisturizing area, and the area after spraying is covered and shielded by the first and second shielding plates, thereby reducing the evaporation of water. Furthermore, while ensuring automatic spraying, it can also improve the guarantee of continuous moisturization after spraying, with a high degree of uniform spraying and greatly enhanced practicality;

[0023] 2. In order to improve the control of the spray water pressure, the water pressure regulating mechanism is set to include a water storage chamber arranged on the movable mounting frame and a multi-stage pressure regulating chamber connected to the water storage chamber. The multi-stage pressure regulating chamber includes a number of piston chambers communicated with the water storage chamber and air pump regulating structures arranged in each piston chamber. Each piston chamber is respectively arranged along the length direction of the water storage chamber. By arranging the multi-stage pressure regulating chamber in this way, when the pressure in the water storage chamber increases or decreases, the piston chambers can be pressurized or decompressed by the air pump. Decompression is to enable the water in the water storage chamber to enter the rodless cavity of the piston chamber, thereby relieving the water pressure in the water storage chamber. Similarly, when increasing the pressure in the water storage chamber, the piston chambers can be pressurized by the air pump, causing the water in the rodless cavity of the piston chamber to enter the water storage chamber, thereby increasing the water pressure of the water outlet and ensuring continuous control of the water outlet pressure;

[0024] 3. Further, the air pump regulating structure is set to include a piston body arranged in the piston chamber, a return spring arranged in the rod chamber of the piston chamber, a pressure application chamber connected to the piston chamber, a pressure application plate arranged in the rodless cavity of the pressure application chamber and connected to the piston body through a piston rod, a pressure application spring arranged in the rodless cavity of the pressure application chamber, and an air pump for applying pressure to the rod chamber or the rodless cavity of the pressure application chamber. The piston chamber and the pressure application chamber are communicated. By controlling the pressure in the pressure application chamber, pressure application control of the piston body in the piston chamber is formed. A pressure sensor is provided at the water outlet of the water storage chamber. The multi-stage pressure regulating chamber is configured such that when the pressure value detected by the pressure sensor is less than the set minimum value, pressure is applied to the rodless cavity of the pressure application chamber. On the contrary, when the pressure value detected by the pressure sensor is greater than the set maximum value, pressure is applied to the rod chamber of the pressure application chamber. By changing the pressure value at the water outlet, it is judged that the water outlet can be controlled at a constant pressure value, achieving the effect of uniform spraying and also improving the protection of the concrete foundation;

[0025] 4. In the moisture retention method of the present invention, by installing relative to the above-mentioned moisture retention and curing device, through the installation of the mounting plate, the first shielding plate, and the second shielding plate, a dual anti-evaporation effect is formed, and through continuous spraying on the concrete foundation for moisture retention and curing. At the same time, in step S6, a humidity sensor for detecting the humidity of the concrete is added, which can detect the humidity of the concrete in real time, transmit the detected data to the control center, then analyze the data of the concrete humidity to form a humidity change curve, and drive the spraying device to perform continuous moisture retention operations according to the humidity change curve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Refer to Figures 1 to 3 To further describe an embodiment of a concrete moisture retention and curing device and its construction method for building construction according to the present invention.

[0031] For ease of explanation, in the embodiments, spatial relative terms such as "upper", "lower", "left", "right", etc. are used to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientations shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein can be interpreted accordingly.

[0032] Moreover, relative relationship terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0033] A concrete moisture conservation device for building construction includes a movable mounting frame 1, and further includes a plurality of mounting plates 2 arranged on the movable mounting frame 1, a first shielding plate 3 and a second shielding plate 4 arranged on each of the mounting plates 2. A plurality of movable mounting frames 1 are arranged along the periphery of the concrete moisture conservation area. A plurality of spray heads 5 are arranged on each of the mounting plates 2, and each of the spray heads 5 is communicated with a water supply device. A water pressure regulating mechanism 101 connected to the corresponding spray head 5 is arranged on each of the movable mounting frames 1. The first shielding plate 3 is arranged on the upper side of the side of the mounting plate 2 facing away from the concrete moisture conservation area, and the first shielding plate 3 is arranged to incline downward. One or more second shielding plates 4 are installed on the top end of the mounting plate 2 through a mounting mechanism.

[0034] In the present invention, by arranging the movable mounting frame 1 in the concrete area that needs moisture conservation operation, then installing the mounting plate 2 on the movable mounting frame 1, and arranging the spray head 5 and the first and second shielding plates on the mounting plate 2, the spraying and moisturizing of the concrete moisture conservation area are realized, and the area after spraying is covered and shielded by the first and second shielding plates, so as to reduce the evaporation of water. Furthermore, while ensuring automatic spraying, the guarantee of continuous moisturizing after spraying can also be improved, and the spraying uniformity is high, and the practicability is greatly improved. And in the embodiments of the present invention, a water pressure regulating mechanism 101 is also added, which can be used to stabilize the water output of the spray head 5. When the water pressure at the water outlet changes, the water pressure regulating mechanism 101 can adjust the water pressure at the water outlet to form a stable output at the water outlet, ensuring the uniformity of moisturizing the concrete area.

[0035] Specifically, the installation mechanism is set to include a slide rail 20 opened on the upper part of the mounting plate 2, a side chute 21 arranged outside the slide rail 20, and a slider 22 arranged on the second shield 4 and adapted to the slide rail 20. The inner diameter of the side chute 21 is greater than that of the slide rail 20. Sliders 22 are arranged at both ends of the second shield 4. The width of the slider 22 is equal to the width of the slide rail 20. A limit block 23 is installed on the slider 22, and the width of the limit block 23 is equal to the width of the side chute 21. Since the area that the second shield 4 needs to cover is relatively large, the installation difficulty is relatively high. However, through the above installation mechanism, the slide rail 20 and the slider 22 are matched, and the side chute 21 and the limit block 23 are matched to form a limit from the side direction, thereby improving the fixing effect of the mounting plate 2 and the second shield 4, and greatly enhancing the stability.

[0036] Specifically, the water pressure regulating mechanism 101 includes a water storage chamber 10 arranged on the movable mounting frame 1 and a multi-stage pressure regulating chamber 11 connected to the water storage chamber 10. The multi-stage pressure regulating chamber 11 includes a plurality of piston chambers 110 communicated with the water storage chamber 10 and an air pump regulating structure 12 arranged in each piston chamber 110. Each of the piston chambers 110 is arranged along the length direction of the water storage chamber 10. In order to improve the control of the spray water pressure, the water pressure regulating mechanism 101 is set to include a water storage chamber 10 arranged on the movable mounting frame 1 and a multi-stage pressure regulating chamber 11 connected to the water storage chamber 10. The multi-stage pressure regulating chamber 11 includes a plurality of piston chambers 110 communicated with the water storage chamber 10 and an air pump regulating structure 12 arranged in each piston chamber 110. Each piston chamber 110 is arranged along the length direction of the water storage chamber 10. The multi-stage pressure regulating chamber 11 is distributed, so that when the pressure in the water storage chamber 10 increases or decreases, the air pump 125 can apply pressure or reduce pressure to the piston chamber 110. Reducing the pressure is to enable the water in the water storage chamber 10 to enter the rodless cavity of the piston chamber 110, thereby relieving the water pressure in the water storage chamber 10. Similarly, when increasing the pressure in the water storage chamber 10, the air pump 125 can apply pressure to the piston chamber 110, so that the water in the rodless cavity of the piston chamber 110 enters the water storage chamber 10, thereby increasing the water pressure of the outlet water and ensuring the continuous control of the outlet water pressure.

[0037] The function of setting the water pressure regulating mechanism 101 is that in a traditional moisturizing and curing device, relying solely on the water pressure output by the water pump cannot fully ensure the stability of the output, and the final spraying effect will also be affected by the change of the water pressure. However, by using the water pressure regulating mechanism 101 to stabilize the change of the water pressure, the water pressure during spraying can be made constant, thereby improving the uniformity of moisturizing.

[0038] Specifically, the air pump regulating structure 12 includes a piston body 120 disposed in the piston chamber 110, a return spring 121 disposed in the rod chamber of the piston chamber 110, a pressure application chamber 122 connected to the piston chamber 110, a pressure application plate 123 disposed in the pressure application chamber 122 and connected to the piston body 120 through a piston rod, a pressure application spring 124 disposed in the non-rod chamber of the pressure application chamber 122, and an air pump 125 for applying pressure to the rod chamber or the non-rod chamber of the pressure application chamber 122. A pressure sensor 126 is provided at the water outlet in the water storage chamber. The multi-stage pressure regulating chamber 11 is configured to apply pressure to the non-rod chamber of the pressure application chamber 122 when the pressure value detected by the pressure sensor 126 is less than the set minimum value. Conversely, when the pressure value detected by the pressure sensor 126 is greater than the set maximum value, pressure is applied to the rod chamber of the pressure application chamber 122.

[0039] Further, the air pump 125 regulating structure 12 is set to include a piston body 120 disposed in the piston chamber 110, a return spring 121 disposed in the rod chamber of the piston chamber 110, a pressure application chamber 122 connected to the piston chamber 110, a pressure application plate 123 disposed in the pressure application chamber 122 and connected to the piston body 120 through a piston rod, a pressure application spring 124 disposed in the non-rod chamber of the pressure application chamber 122, and an air pump 125 for applying pressure to the rod chamber or the non-rod chamber of the pressure application chamber 122. The piston chamber 110 and the pressure application chamber 122 are communicated. By controlling the pressure in the pressure application chamber 122, pressure application control of the piston body 120 in the piston chamber 110 is formed. A pressure sensor 126 is provided at the water outlet in the water storage chamber. The multi-stage pressure regulating chamber 11 is configured to apply pressure to the non-rod chamber of the pressure application chamber 122 when the pressure value detected by the pressure sensor 126 is less than the set minimum value. Conversely, when the pressure value detected by the pressure sensor 126 is greater than the set maximum value, pressure is applied to the rod chamber of the pressure application chamber 122. By changing the pressure value at the water outlet, it is judged whether the water outlet can be controlled at a constant pressure value, so as to achieve the effect of uniform spraying and improve the protection of the concrete foundation.

[0040] In the embodiment of the present invention, when curing the concrete area to be cured, the periphery of the concrete area is distributed in a surrounding manner, and the concrete area is sprayed through the uniformly distributed spray heads 5. At the same time, the concrete area is shielded by the first shield 3 and the second shield 4, simulating the traditional way of laying a protective film. However, in this application, by using double shields and cooperating with real-time detection of the humidity of the concrete, it is judged whether spraying is needed, so that the whole set of concrete moisture conservation device can be continuously reused, thereby achieving the effect of continuous conservation and moisture retention. Moreover, the consumption brought by the above equipment to the protective film is zero, and it also makes the maintenance and cleaning of the concrete more convenient, greatly improving the practicability.

[0041] Specifically, each of the piston chambers 110 is respectively arranged at the water outlet end, the water inlet end of the water storage chamber, and the middle area of the water storage chamber. In the embodiment of the present invention, arranging the piston chambers 110 at the above three positions can form the functions of shunting and pressure reduction at different positions and increasing the flow rate by applying pressure at multiple positions, so that when the pressure value at the water outlet is monitored to change greatly, corresponding solutions can be formed. And in the embodiment of the present invention, ensuring the balance of water pressure can stably output the spray head 5, thereby providing moisture conservation for the concrete foundation.

[0042] Specifically, the length of the second baffle 4 is equal to the distance between the two opposite mounting plates 2, which is convenient for the installation of the second baffle 4 and has high installation convenience.

[0043] A construction method for a concrete moisture conservation device for building construction applicable to the above, the concrete moisture conservation construction method specifically includes the following steps: S1.

[0046] In the embodiment of the present invention, for the fixing method of the inclined mounting plates 2, the oppression on the water pipe can be reduced, thereby ensuring the stability of water pressure.

[0047] S4. Install the first baffle 3: Install the first baffle 3 on the mounting plates 2 installed in S3; the first baffle 3 is installed at the inclined plane position of the mounting plates 2, and a plurality of first baffles 3 are installed in parallel on both sides of the mounting plates 2, and the length of the first baffle 3 increases successively from bottom to top of the concrete foundation pit.

[0048] S5.

[0050] S7. Analysis of the detected data: Transmit the concrete humidity data detected in S6 to the control center. Through the analysis of the control center, a change curve of the concrete humidity data is formed, and according to the change curve of the humidity, the spraying equipment is driven to perform continuous moisturizing operations.

[0051] In the moisturizing method of the present invention, by installing relative to the above-mentioned moisturizing and curing device, through the installation of the mounting plate 2, the first shielding plate 3 and the second shielding plate 4, a double anti-evaporation effect is formed, and through continuous spraying on the concrete foundation, moisturizing and curing are carried out. At the same time, in step S6, a humidity sensor for detecting the humidity of the concrete is additionally installed, which can detect the humidity of the concrete in real time, and set the humidity value when moisturizing operations are required. After transmitting the detected data to the control center, the data of the concrete humidity is analyzed to form a change curve of the humidity, and according to the change curve of the humidity, the spraying equipment is driven to perform continuous moisturizing operations.

[0052] In the embodiment of the present invention, there is also the following structure. Specifically, a plurality of ventilation holes are opened on the second shielding plate 4. A steam collection chamber is arranged on the lower surface of the second shielding plate 4 below the ventilation holes. The cross-section of the steam collection chamber is trapezoidal. A through hole is opened in the middle of the steam collection chamber. The distribution of the steam collection chamber is such that when there are dewdrops at night, the dewdrops are collected and injected into the concrete foundation through the through hole; a plurality of water collection grooves are opened on the lower surface of the second shielding plate 4.
