Description

Technical Field

[0001] The present invention belongs to the technical field of automatic spraying and curing of concrete, and specifically relates to a distributed ground-inserted bracket type automatic spraying and curing system for concrete. Background Art

[0002] In construction projects, the quality and durability of concrete structures are of crucial importance, and concrete curing is a key link to ensure its performance. Traditional concrete curing methods mostly rely on manual operations, such as manual watering, which not only consumes a large amount of manpower, but also the curing effect is greatly affected by human factors, making it difficult to ensure uniformity and stability. With the continuous expansion of the scale and increasing complexity of construction projects, the construction industry urgently needs an efficient, intelligent and precise concrete curing system to meet the needs of large-scale and high-efficiency construction, while ensuring the safety and durability of concrete structures.

[0003] In the existing concrete curing technology, some automatic spraying devices adopt a simple timed spraying method, controlling the opening and closing of water pumps or valves through timers to achieve periodic spraying. In terms of pipeline layout, a fixed and single method is mostly used, which is difficult to meet the needs of different building structures and construction scenarios. For example, some spraying systems simply lay water pipes near the concrete surface and spray through ordinary nozzles. In complex building structures, such as scenes with high ground floors and enclosed rooms in residential buildings, the existing technology cannot achieve comprehensive and uniform spraying and curing.

[0004] The existing automatic spraying devices lack intelligent control and cannot adjust spraying parameters in real time according to the actual curing needs of concrete, such as humidity and temperature changes. In complex building structure scenarios, their pipeline layout methods cannot meet the requirements of spraying coverage, and it is easy to have spraying dead corners, resulting in poor concrete curing effects. Moreover, the traditional curing system is cumbersome to operate during installation and disassembly, consuming a large amount of time and manpower. In addition, the existing technology has a low utilization efficiency of water resources and there is a waste phenomenon. Summary of the Invention

[0005] In view of this, the present invention provides a distributed ground-inserted bracket type automatic spraying and curing system for concrete, which solves the problems of high labor cost, unstable curing effect, inability to adapt to complex building structure scenarios and water resource waste in traditional concrete curing methods.

[0038] Furthermore, in the above technical solution, a spray pipeline 2 is also provided inside the concrete, and is connected to the spray pipeline 2 on the concrete surface via a three-way valve.

[0039] Furthermore, in the above technical solution, the nozzle 3 is a desktop adjustable rotary spray structure, and under a water pressure of 0.3-0.6MPa, its spray coverage radius is not less than 2.5 meters, and the spray uniformity deviation is controlled within ±10%.

[0040] Furthermore, in the above technical solution, an anti-clogging structure is provided inside the nozzle 3 to ensure the anti-clogging performance of the nozzle 3 .

[0041] Furthermore, in the above technical solution, the ground plug bracket 1 is made of high-strength PVC material, which is convenient for construction workers to carry and transport.

[0042] Furthermore, in the above technical solution, a threaded interface is designed on the upper part of the ground bracket 1, which can be threaded to an extended pipe. The length of each extended pipe is 30 cm. According to the actual spray height requirements, 1-5 extended pipes are added to meet various construction scenarios.

[0043] Furthermore, in the above technical solution, the sprinkler pipeline 2 uses a PVC transparent hose as a water pipe for connecting the floor water intake point and the sprinkler bracket; the bendable angle of the sprinkler pipeline 2 is not less than 120°.

[0044] Furthermore, in the above technical solution, the water valve is connected to the wireless network through the Bluetooth connection of the mobile phone and in cooperation with the gateway.

[0045] Furthermore, in the above technical solution, a remote switch and a timing device are provided in the water valve, so that the water valve has the functions of real-time remote switching and timing setting of the spraying time and interval time.

[0046] The spray pipeline 2 is fixed on the surface and inside of the casting template 4, and the spray pipeline 2 inside the casting template 4 is connected to the spray pipeline 2 on the surface through a three-way valve; the casting template 4 is used to fix the spray pipeline 2 and position the nozzle 3; the depth of the pre-buried spray pipeline 2 inside the casting template 4 is 1 / 3-1 / 2 of the depth of the concrete poured in the casting template 4.

[0047] The casting formwork 4 includes a fixed-layer formwork 41, a reinforcing-layer support frame 42, and a grouting channel 43. The fixed-layer formwork 41 consists of an inner formwork 411 and an outer formwork 412. A cavity for accommodating the first fixed layer and the second fixed layer of concrete is formed between the inner formwork 411 and the outer formwork 412. The inner formwork 411 and the outer formwork 412 are connected by a connecting component, and the shape matches the surface shape of the building body, which is used to define the shape and thickness of the first fixed layer and the second fixed layer; The reinforcing-layer support frame 42 is arranged between the inner formwork 411 and the outer formwork 412 and is used to support and fix the alkali-resistant mesh cloth; The reinforcing-layer support frame 42 is bolted to the inner formwork 411 and the outer formwork 412 to ensure that the alkali-resistant mesh cloth is located between the inner formwork 411 and the outer formwork 412; The grouting channel 43 is arranged on the outer formwork 412 and is used for pouring concrete; The grouting channel 43 and the outer formwork 412 are connected by a U-shaped fixing piece, and the shape is a funnel-shaped tube, which is used to guide the concrete into the fixed-layer formwork 41 to ensure that the concrete fills the entire formwork; The fixed-layer formwork 41, the reinforcing-layer support frame 42, and the grouting channel 43 form an integral casting system, which is used to realize the integral casting of the first fixed layer, the reinforcing layer, and the second fixed layer;

[0048] The connecting component includes bolts and nuts. The bolts pass through the preset holes on the inner formwork 411 and the outer formwork 412 and are tightened by nuts to realize the fixed connection between the inner formwork 411 and the outer formwork 412. By adjusting the tightness of the bolts, the distance between the inner formwork 411 and the outer formwork 412 can be finely adjusted to adapt to the pouring requirements of concrete with different thicknesses;

[0049] The reinforcing-layer support frame 42 is a prefabricated steel bar grid, and its grid size matches the grid size of the alkali-resistant mesh cloth. The alkali-resistant mesh cloth is fixed on the steel bar grid by spot welding to ensure that the alkali-resistant mesh cloth remains flat during the concrete pouring process and prevent it from shifting or deforming;

[0050] A plurality of grouting channels 43 are arranged and evenly distributed on the surface of the outer formwork 412. Each grouting channel 43 is connected to an independent conveying pipeline. By controlling the concrete flow rate of each conveying pipeline, it is used to realize the precise control of the concrete pouring speed in different areas, ensure the uniform filling of the concrete, and avoid the appearance of voids or defects;

[0051] A vibrator 44 is arranged on the outer formwork 412 and is used to vibrate the casting formwork 4 and the internal concrete during the concrete pouring process, improve the compactness of the concrete, reduce the generation of air bubbles and honeycombs, and improve the overall quality of the concrete;

[0052] The surface of the inner formwork 411 is coated with a release agent, which is used to demold after the concrete pouring is completed, reduce the adhesion between the concrete and the casting formwork 4, prevent damage to the concrete surface, improve the demolding efficiency, and extend the service life of the formwork.

[0053] The casting formwork 4 further includes a positioning device 45 which is arranged on the outer side of the casting formwork 4 and is used to fix the casting formwork 4 at a predetermined position on the surface of the building main body, ensuring the stability and casting accuracy of the casting formwork 4.

[0054] The vibrator 44 includes a housing 441, an air duct 442, an air suction valve 443, a compression cylinder 444 and a nozzle 445. The housing 441 is fixed outside the casting formwork 4; one end of the air duct 442 is hermetically connected to the side wall of the housing 441, and the other end extends to the surface of the housing 441 for sucking air into the interior of the housing 441; a compression cylinder 444 is fixed inside the housing 441, and the compression cylinder 444 corresponds to the position of the air duct 442 for compressing the air sucked by the air duct 442; one end of the nozzle 445 is connected through the housing 441, and the other end is not hermetically connected to the outside of the casting formwork 4 for forming vibration on the concrete inside the casting formwork 4 by changing the rate and flow of the air compressed by the compression cylinder 444; an air suction valve 443 is fixed on the air duct 442, and an air outlet valve 446 is fixed on the nozzle 445. After the air suction valve 443 and the air outlet valve 446 are closed, the interior of the housing 441 is sealed for quickly compressing gas;

[0055] The air duct 442 is in a structure formed by combining two funnel shapes, and the cross-sectional areas at both ends are larger than the cross-sectional area in the middle for forming a pressure difference;

[0056] A pressure sensor is fixed on the inner wall of the housing 441 for monitoring the pressure change inside the housing (41).

[0057] The vibration frequency and intensity of the nozzle 445 increase and decrease in a Fibonacci sequence pattern for adjusting the overall performance of the vibrator 44 using different Fibonacci values in different cycles, so as to vibrate the concrete precisely. Through gradually increasing frequency and flow, the air bubbles in the concrete are more evenly distributed, improving the density and strength of its structure;

[0058] There are multiple nozzles 445, and the vibration frequency and flow of each nozzle 445 are set according to different values of the Fibonacci sequence, so that the multiple nozzles 445 form a coordinated vibration.

[0059] A heat preservation core material is fixed on the side of the inner formwork 411 away from the outer formwork 412, and interface tooth grooves are arranged on the side of the heat preservation core material connected to the inner formwork 411. The interface tooth grooves are used to enhance the bonding force and biting force of the connection between the heat preservation core material and the inner formwork 411.

[0060] The interface alveoli are multiple regularly arranged inverted frustum-shaped grooves and strip-shaped connectors. The strip-shaped connectors are trapezoidal. The width of the upper bottom surface of the trapezoid is less than the width of the bottom of the inverted frustum-shaped groove, and the width of the lower bottom surface is greater than the width of the top of the inverted frustum-shaped groove. The strip-shaped connectors are embedded in the inverted frustum-shaped grooves and fit tightly with the inner template 411. The material of the strip-shaped connectors is one of modified asphalt, polyurethane, and silicone rubber. Reinforcing ribs are provided at the bottom of the inverted frustum-shaped grooves. The reinforcing ribs are convex structures integrally formed with the thermal insulation core material. The shape of the reinforcing ribs is grid-shaped, which is used to enhance the strength of the inverted frustum-shaped grooves, prevent deformation or damage during the concrete pouring process, and further improve the overall stability.

[0061] The surface of the strip-shaped connectors is provided with rough textures or bonding coatings, which are used to increase the contact area and friction between the strip-shaped connectors and the concrete, thereby improving the bonding force and biting force.

[0062] In the trapezoidal cross-sectional structure of the strip-shaped connectors, the ratio of the width of the lower bottom surface to the width of the top of the inverted frustum-shaped groove is controlled between 1.1 and 1.5, which is used to ensure that there is enough contact area between the strip-shaped connectors and the top of the inverted frustum-shaped groove, and at the same time avoid the strip-shaped connectors being too wide and affecting the flow and biting of the concrete.

[0063] The second embodiment of the present invention includes:

[0064] 1. Intelligent water valve:

[0065] The intelligent water valve is connected to the floor water intake point through a threaded end. As the front-end control device of the entire spray curing system, it can achieve mobile phone Bluetooth connection within 15m, cooperate with the gateway to achieve wireless network connection, and at the same time can control multiple intelligent water valves with one mobile phone. It has functions such as real-time remote switch, timing setting of spray time and interval time, and can view spray curing records. After installation, it is paired through mobile phone Bluetooth or wireless network to ensure a stable connection between the water valve and the control device. During the debugging process, users can set and test various functions through the mobile phone APP to ensure that the water valve can accurately respond to instructions.

[0066] 2. Ground plug bracket:

[0067] It is made of high-strength PVC material as a whole, with the remarkable feature of light weight, which is convenient for construction workers to carry and transport. The lower part of the bracket is a triangular bracket structure that can be opened and adjusted. It is connected by a specially designed hinge and can flexibly adjust the opening and closing angle according to the ground conditions and spraying requirements. The opening and closing angle range is 30° - 120° to ensure the stable support of the bracket. The upper part of the bracket is a telescopic structure with an adjustment range of 0.7 - 1.5m, which can adapt to concrete components of different heights. A special water inlet is provided at the lower part of the bracket, and the specification of the water inlet is precisely matched with the interface of the 1 / 4 water valve. The 1 / 4 water valve connecting pipe can be conveniently connected to the water receiving point to ensure stable water supply. The upper part of the bracket is designed with a standard threaded interface, and extended pipes can be threaded. The length of each extended pipe is 30cm. According to the actual spraying height requirements, 1 - 5 extended pipes can be flexibly added to meet diverse construction scenarios.

[0068] 3. Spraying pipeline: Use a PVC transparent flexible hose as the water pipe for connecting the floor water intake point and the spraying bracket. The hose has good flexibility, the bending angle is not less than 120°, and there is no rupture after bending 500 times. It has certain corrosion resistance, and when placed in the simulated construction site environment for 5 days, the material performance does not decrease significantly.

[0069] 4. Sprinkler head: For the ground-inserted bracket type system, a tabletop adjustable rotary spray nozzle is selected. Under the water pressure of 0.3 - 0.6MPa, the spray coverage radius of the sprinkler head is not less than 2.5 meters, and the deviation of spray uniformity is controlled within ±10%. The sprinkler head has good anti-blocking performance. When continuously used for 50 hours in the simulated spraying water containing certain impurities (the sediment content does not exceed 0.5%), the blockage rate is less than 5%, and the service life is not less than 1000 hours.

[0070] The third embodiment of the present invention is the installation steps of the spraying maintenance system:

[0071] 1. Draw the layout diagram of the spraying pipeline in the construction section: According to the characteristics of the building structure, such as the height of the ground floor of the residence and the layout of the enclosed rooms, accurately draw the layout diagram of the spraying pipeline. Determine the installation positions of the ground-inserted brackets to ensure uniform spraying coverage and avoid spraying dead angles. Mark the positions of the local water intake points to prepare for the subsequent pipeline embedding.

[0072] 2. Embed the pipelines at the local water intake points: Before the floor concrete is poured, carry out the embedding work of the pipelines at the local water intake points according to the layout diagram. Connect the floor water intake point and the expected spraying water point with the embedded water pipes, and make a stub connection at the fire hydrant position. The embedded pipelines use corrosion-resistant pipes to ensure that they are not damaged during the concrete pouring process, and the embedding depth meets the design requirements, generally 1 / 3 - 1 / 2 of the floor thickness.

[0073] 3. Pour concrete: After completing the pipeline embedding, carry out the concrete pouring operation. During the pouring process, pay attention to protecting the embedded pipelines to avoid damage to the pipelines caused by equipment such as vibrating rods. Ensure the quality of concrete pouring and guarantee its density and flatness.

[0074] 4. Remove the formwork of vertical components: When the concrete reaches a certain strength, carry out the formwork removal work for vertical components. Be careful during the formwork removal process to avoid damaging the concrete surface and embedded pipelines. After formwork removal, clean the sundries and dust on the concrete surface to prepare for the subsequent installation work.

[0075] 5. Install the intelligent water valve: Install the intelligent water valve, 1-to-4 water valve, and filter according to the design requirements. First, determine the installation position and select an area close to the water source and convenient for wiring and operation. Connect the 1-to-4 water valve to the main water supply pipeline, ensure the connection is tight, and use sealing tape or sealant for sealing treatment to prevent water leakage. Then install the intelligent water valve and firmly connect it to the 1-to-4 water valve through special connecting pipe fittings. Finally, install the filter, and the filter is installed at the water inlet end of the water valve. After installation, conduct the initial water passing test to check the airtight performance of the water valve and ensure no water leakage within the water pressure range of 0.1 - 1 MPa. Through the settings of the mobile phone APP or the device terminal, test the timed maintenance function and remote control function of the intelligent water valve, set different timed spraying times and remote control instructions, and check the response time and instruction transmission success rate.

[0076] 6. Install the ground plug bracket and connect the water: According to the position determined by the layout drawing, support the ground plug bracket at the center position of the spraying area, connect the connection interface at the bottom of the bracket to the outlet of the embedded pipeline, and ensure the connection is tight and does not leak water. Arrange the spraying pipelines according to the designed spraying range and angle. Finally, install the desktop adjustable rotary spray nozzle at the end of the spraying pipeline, adjust the angle of the nozzle, and ensure that the spray coverage meets the requirements.

[0077] 7. Water curing: With the help of the intelligent water valve, accurately set key parameters such as spraying time, frequency, and water volume. According to the scientific standards and actual needs of concrete curing, in the first 3 days after concrete pouring, set to spray once every 15 minutes, and the spraying duration for each time is 3 minutes.

[0078] In terms of the spraying water volume, when the water pressure is maintained in the standard range of 0.3 - 0.6 MPa, the water output of the nozzle is controlled at 5 - 8 liters per minute. This water volume can not only ensure that the concrete surface is fully wetted but also avoid wasting water resources.

[0079] After the system starts up, under this water pressure condition, the sprinkler head can achieve uniform coverage with an effective sprinkling radius of approximately 3.0 m. Within this 3.0 m effective sprinkling radius, the effective sprinkling height is approximately the height of the support h + 50 cm, ensuring that concrete components can be sprinkled and cured within the corresponding height range.

[0080] During the continuous progress of the curing operation, the operating conditions of the sprinkler system are carefully inspected regularly. Focus on checking the spraying effect of the sprinkler head to ensure that the spray is in a uniform swirling state, the coverage range meets the requirements of the effective sprinkling radius, and there are no obvious uneven spraying or clogging phenomena. At the same time, comprehensively check all connection points of the sprinkler pipeline to see if there is any water leakage problem, including the connection between the ground plug support and the sprinkler pipeline, the joints between the sprinkler pipelines, and the connection parts between the sprinkler head and the pipeline. Once problems such as abnormal spraying of the sprinkler head or water leakage of the pipeline are found, immediately suspend the sprinkler system and organize professional maintenance personnel for repair. For the problem of sprinkler head clogging, clean the impurities inside the sprinkler head in time; if it is a pipeline water leakage, according to the specific situation, tighten the loose joints, or replace the damaged seals, connecting pipe fittings, etc., to ensure that the sprinkler system is always in good operating condition and provides stable and reliable guarantee for concrete curing.

[0081] Specifically, the principle of the present invention is: during use, draw the layout diagram of the sprinkler pipeline in the construction section, pre-bury the pipeline at the local water intake point, pour concrete, remove the formwork of the vertical components, install the intelligent water valve, install and connect the water to the ground plug support, and start water curing.

[0082] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
