Description

Technical Field

[0001] This utility model relates to a concrete curing device, specifically an automatic spray curing system for independent structural columns. Background Technology

[0002] In the field of construction engineering, the curing of concrete after pouring is a crucial step in ensuring its strength, durability, and preventing cracking. For independent structural columns, the quality of curing directly affects the stability and safety of the overall structure.

[0003] Currently, common maintenance methods mainly include mulching and manual watering. While mulching with materials such as geotextiles or plastic films can theoretically retain moisture, in actual working conditions such as hot summers and strong winds, the mulching material is very easy to peel off from the concrete surface, making it difficult to maintain a continuous moist state. This leads to untimely and uneven maintenance, causing harmful cracks to appear on the surface of the structural columns due to excessive water loss.

[0004] The traditional method of relying on manual, timed watering has more significant drawbacks. Firstly, manual watering with handheld hoses or buckets results in imprecise water flow control, making it difficult to ensure that all sides of the structural columns receive uniform and sufficient moisture, often creating blind spots and affecting the final homogeneity and strength development of the concrete. Secondly, this method requires a large labor force, and the timeliness and continuity of curing are difficult to guarantee, especially at night, at heights, or inaccessible work areas. This not only creates significant safety management blind spots but also makes the curing effect extremely unstable.

[0005] To overcome the shortcomings of manual maintenance, automated maintenance technology has emerged. Currently, some devices designed for automated sprinkler systems have indeed appeared on the market. For example, Chinese patents CN112796231A and CN107903083B both propose using "flexible structures" such as steel wire ropes and flexible belts to cantilever and fix the sprinkler ring pipe to the structural column. However, this type of "flexible fixing" solution has revealed significant limitations in actual construction applications: First, the installation process is cumbersome, requiring workers to repeatedly adjust and tighten the steel wire ropes at heights to ensure the basic stability of the device, resulting in low installation efficiency; second, stability and reliability are insufficient, as the flexible connection is prone to swaying or even slipping under wind or external disturbances, affecting not only the accuracy of sprinkler positioning but also posing a safety hazard of falling objects from heights. Utility Model Content

[0006] The purpose of this invention is to provide an automatic spraying maintenance system for independent structural columns to solve the problems mentioned in the background art.

[0017] An adjusting column is rotatably installed on the lower part of the outer frame, and a spray pipe is provided on the adjusting column;

[0018] An adjusting column is fixedly installed at the bottom of the frame. The adjusting column passes through the support frame and can slide on the support frame.

[0020] Preferably, a horizontal plate is fixedly installed on one side of the outer frame, and a lead screw is rotatably installed on the horizontal plate;

[0021] An extension plate is fixedly installed on one side of the frame, and the extension plate is threadedly connected to the lead screw.

[0022] Preferably, a mounting base is fixedly installed at the bottom of the outer frame, and the top of the adjusting column is rotatably installed with the mounting base via a rotating shaft.

[0023] Preferably, the support frame includes two side plates, and a support shaft is fixedly installed at the edge between the two side plates.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention utilizes a high-pressure water pump for automatic, continuous spraying via spray pipes encircling the frame and evenly distributed atomizing nozzles.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please refer to Figures 1-4. This embodiment discloses an automatic spray curing system for independent structural columns.

[0040] Including frame 1, the dimensions of frame 1 can be set according to the cross-sectional dimensions of the independent columns. For example, a custom maintenance system frame can be made using 50*50*3mm square steel. Figure 1 As shown, the cross-section of frame 1 is a square structure, consisting of upper and lower square frame structures combined with supporting brackets. The frame is supported by two fixed crossbars 2 made of 50*50*3mm square steel for mounting and fixing to the top of the structural columns. Additionally, two connecting vertical bars, each 500mm high and made of 50*50*3mm square steel, are installed on each side to maintain the frame's stability.

[0041] A 20mm spray pipe 3 is wrapped around the lower layer of the frame. The spray pipe 3 can be tied to the lower layer of the frame using straps or ropes. At the same time, a matching 20mm high-pressure spray head is installed every 300mm. The spray head is a common atomizing spray head (which can be divided into No. 0 atomizing spray head, No. 1 atomizing spray head, No. 2 atomizing spray head, No. 3 atomizing spray head, No. 4 atomizing spray head, etc.), which can be purchased from the market. A high-pressure water pump (such as WBS series stainless steel centrifugal corrosion-resistant electric pump or industrial-grade plunger pump) is connected to the spray pipe. Water mist is generated from the spray head and sprayed evenly on each surface of the structural column. At the same time, the water mist flows down evenly, achieving a uniform curing effect. There is no need for manual watering and control, which improves efficiency and ensures the curing effect.

[0042] In this embodiment, during installation, it is only necessary to hoist the frame 1 above the structural column and place it on the top of the structural column. The fixed crossbar 2 is placed on the top of the structural column to support the frame 1, which can complete the quick installation of the frame 1.

[0043] Since the top of the structural column will have exposed steel bars, the fixed crossbar 2 is located between the exposed steel bars. The steel bars limit the fixed crossbar 2, which can prevent the frame 1 from sliding or shifting on the structural column. This solution is designed in combination with actual use and the characteristics of the structural column, and the structure is simpler and more practical.

[0044] In actual construction, the cross-sectional dimensions of independent columns often vary depending on the project and load-bearing requirements. Therefore, to accommodate independent columns with different cross-sectional dimensions, frame 1 is designed as a variable-size structure. The specific design is as follows:

[0045] like Figure 5 As shown, frame 1 includes two splicing frames 101 and two splicing frames 102, as follows: Figure 5 As shown, both splicing frame 101 and splicing frame 2 102 are L-shaped structures. The two splicing frames 101 and the two splicing frames 2 102 are staggered and spliced ​​together to form a frame structure.

[0046] The splicing frame 101 has insertion interfaces 104 at both ends, and the two ends of the splicing frame 2 102 can be respectively inserted into the insertion interfaces of the two splicing frames 101.

[0047] Multiple matching through holes 103 are provided at both ends of the insertion interface and the splicing frame 2 102. Fixing bolts (with caps) are installed in the through holes 103 by threads to fix the splicing frame 1 101 and the splicing frame 2 102. In order to be compatible with the splicing frame 1 101 and the splicing frame 2 102, the fixing crossbar 2 includes a crossbar 1 21 and a crossbar 2 22. The crossbar 2 22 is inserted into the crossbar 1 21 and can slide in the crossbar 1 21. Multiple through holes are provided on the crossbar 1 21 and the crossbar 2 22. Bolts are threaded into the through holes to fix the crossbar 1 21 and the crossbar 2 22.

[0048] When adjusting the size of frame 1, loosen the bolts on splicing frame 101 and splicing frame 202, as well as the bolts on the fixing crossbar 2. Then, slide splicing frame 202 to a suitable position (slightly larger than the independent structural column; adjust according to actual usage requirements). Insert the bolts into the through holes to fix splicing frame 101 and splicing frame 202, and crossbar 101 and crossbar 22. If the through holes are not aligned during adjustment, slightly pull splicing frame 202 or splicing frame 101 to align the two nearest through holes, then tighten the bolts.

[0049] When adjusting the size of the frame, the spray pipe 3 is not tied to the frame structure. After the adjustment is completed, the spray pipe 3 is tied to change the size of the frame structure formed by the spray pipe 3, so as to avoid the spray pipe 3 affecting the adjustment of the frame during the adjustment.

[0050] In this way, the size of frame 1 can be changed to accommodate independent structural columns of different sizes. By designing the main frame as an adjustable structure consisting of two L-shaped splicing frames fixed by plugging and bolting, and by using a telescopic design for the fixing crossbars, the dimensions of the entire frame can be flexibly and conveniently adjusted according to the cross-sectional dimensions of the independent columns. One system can meet the maintenance needs of independent columns of various specifications, significantly reducing equipment procurement and storage costs and improving equipment turnover rate.

[0051] In a further embodiment, the size of the frame formed by the spray pipe 3 can also be adjusted individually. For example... Figure 6-8 As shown, an outer frame 4 is provided on the outside of the frame 1, and the frame length of the outer frame 4 is greater than that of the frame 1.

[0052] An adjusting column 5 is rotatably mounted on the lower part of the outer frame 4. The connection relationship between the adjusting column 5 and the outer frame 4 is as follows: multiple evenly distributed mounting seats 51 are fixedly mounted on the bottom of the outer frame 4, and a rotating shaft 52 is rotatably mounted on the top of the adjusting column 5. The rotating shaft 52 is rotatably mounted to the mounting seats 51, allowing the adjusting column 5 to rotate on the mounting seats 51. In this embodiment, it should be noted that the adjusting columns 5 located at corners are installed as needed, and the movement of the adjusting columns 5 should not interfere with each other or affect the movement of the adjusting columns 5.

[0053] The adjusting column 5 is wrapped with the spray pipe 3, and the spray pipe is tied to the adjusting column 5 with cable ties;

[0054] A support frame 9 is fixedly installed at the bottom of the frame 1, such as... Figure 8 As shown, the support frame 9 includes two side plates 91, and a support shaft 92 is fixedly installed at the edge between the two side plates 91. The side plates 91 are fixedly installed at the bottom of the frame 1. The support shaft 92 is located outside the outermost vertical surface of the frame 1 and close to the bottom edge of the side plate 91, providing sufficient movement space for the adjusting column 5.

[0055] The adjusting column 5 passes between the two side plates 91 and is located on the support shaft 92, that is, the adjusting column 5 passes through the support frame 9 and can slide on the support frame 9;

[0056] An adjustment structure is installed between the outer frame 4 and the frame 1 to adjust the distance between the outer frame 4 and the frame 1.

[0057] A horizontal plate 6 is fixedly installed on one side of the outer frame 4, and a lead screw 7 is rotatably installed on the horizontal plate 6; an extension plate 8 is fixedly installed on one side of the frame 1, and the extension plate 8 is threadedly connected to the lead screw 7. The lead screw 7, the horizontal plate 6, and the extension plate 8 constitute the adjustment structure of the outer frame 4 and the frame 1.

[0058] In this embodiment, the horizontal plate 6 has mounting holes for mounting the lead screw 7. A bearing is mounted on the top of the lead screw 7, and limit rings are welded to the upper and lower sides of the lead screw 7. (It should be noted that the limit rings can only be welded after the lead screw 7 is installed on the horizontal plate 6, and lubricating oil should be applied to the connection between the lead screw 7 and the horizontal plate 6 from time to time to ensure lubrication between the two and reduce rusting.) The limit rings can improve the load-bearing capacity of the lead screw 7.

[0059] like Figure 6 As shown, a rotating handle is fixedly installed on the top of the lead screw 7. Rotating the rotating handle will cause the lead screw 7 to rotate. Under the action of the thread, the frame 1 and the outer frame 4 will move closer or further apart, thereby adjusting the distance between the frame 1 and the outer frame 4.

[0060] Or, such as Figure 7 As shown, a motor is fixedly mounted on the horizontal plate 6, and the output end of the motor is connected to the lead screw 7, providing the power for the lead screw 7 to rotate. The motor is preferably a servo motor with a self-locking function.

[0061] In this embodiment, as Figure 7 and Figure 8 As shown, an extension plate 2 10 is provided at one of the corners of the frame 1. A vertical pole 11 is fixedly installed on the extension plate 2 10. The vertical pole 11 is a cuboid structure. The two vertical poles 11 and the lead screw 7 form a triangular structure. The outer corner of the vertical pole 11 just contacts the two inner corners of the outer frame 4. Threaded holes are provided at the corners of the outer frame 4 and on the vertical pole 11. Fastening bolts are installed in the threaded holes. The fastening bolts can fix the outer frame 4 and the vertical pole 11.

[0062] When it is necessary to adjust the distance between the outer frame 4 and the frame 1, loosen the fastening bolts, and the connection between the upright 11 and the outer frame 4 is released. At this time, the screw 7 can be rotated. Under the action of the thread, the frame 1 moves up or down to the appropriate position. Then, tighten the fastening bolts to fix the upright 11 and the outer frame 4 together.

[0063] When the distance between the outer frame 4 and the frame 1 changes, the adjusting column 5 will rotate around the pivot 52 under the action of the support frame 9. Specifically, as shown... Figure 9 As shown, taking the proximity between outer frame 4 and frame 1 as an example:

[0064] When the two components approach each other, under the constraint of the bearing shaft 92, the adjusting column 5 rotates inward around the rotating shaft 52 towards the inside of the frame 1. Simultaneously, the adjusting column 5 slides inward along the bearing shaft 92, thereby changing the size of the frame structure formed by the spray pipe 3. This also changes the angle of the spray head. This allows for simultaneous adjustment of the spray head angle, making it more versatile.

[0065] It should be noted that the spray pipe 3 in this application is a flexible pipe.

[0066] By adding an outer frame 4, adjusting columns 5, and a screw-adjusting structure, the size of the frame formed by the spray pipes can be independently adjusted while maintaining the fixed dimensions of frame 1. This design allows for precise control of the spray coverage area, further ensuring perfect coverage of columns of different sizes and avoiding resource waste or maintenance blind spots. During the adjustment of the distance between the outer frame 4 and frame 1, this process not only changes the circumference of the spray pipes but also simultaneously alters the spray angle of the spray heads, achieving dynamic optimization of the spray coverage area. For different independent column structures, the angle of the spray heads and the size of the frame formed by the spray pipes can be adjusted to obtain the best spray coverage effect, making it more versatile.

[0067] Furthermore, the use of a lead screw adjustment makes adjustment simpler and more convenient. For construction sites, where there is a lot of dust and other impurities, the lead screw needs regular cleaning and maintenance to prevent dust particles from adhering to it and affecting its normal operation.

[0068] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
