Abstract
Description
Technical Field
[0001] The present invention relates to a concrete curing device, and particularly to a concrete curing device for building construction. Background Art
[0002] Prefabricated buildings require a large number of precast concrete components and fittings, such as floor slabs, wall panels, stairs, etc. These precast concrete components are then transported to the building construction site and assembled at the construction site through reliable connection methods to form a building. The quality of concrete components and fittings is directly related to the quality of prefabricated buildings, and the curing process of concrete components is crucial for the quality of the components.
[0003] The standard humidity during the curing process of concrete components needs to be ≥90%. Below this humidity, there is a risk of concrete cracking. To prevent excessive evaporation of water in the concrete, water needs to be continuously sprayed during the curing process of concrete components to ensure that the humidity meets the standard. Although existing concrete curing devices can complete the water spraying operation, the water spraying method is relatively rough. Usually, the surface of the component is overall oversprayed to avoid the problem of insufficient local spraying amount. This spraying method will inevitably cause some water flow to directly flow away from the surface of the component, resulting in waste of water resources.
[0004] It should be noted that the local humidity difference of larger concrete components is relatively large, especially in some components with irregular shapes. The surface of the concrete component will not dry and lack water synchronously. When some surfaces are dry, water needs to be sprayed for moisture preservation, but the humidity of some other surfaces is still relatively high and does not require water spraying. If water is sprayed at this time, the relatively high-humidity part will not absorb water, resulting in ineffective utilization of the water flow, and will also increase the number of water spraying times, increasing the curing cost. However, if waiting to spray water together when all surfaces are relatively dry, the earlier-dried local parts will crack due to excessive evaporation and water shortage, which will have a negative impact on the overall strength of the concrete component. Therefore, how to perform dynamic monitoring and selective local spraying operations according to the different humidity conditions on the surface of concrete components has become a technical problem to be solved urgently. Summary of the Invention
[0005] Object of the Invention: The object of the present invention is to provide a concrete curing device for building construction to solve the problem of how to perform dynamic monitoring and selective local spraying operations according to the different humidity conditions on the surface of concrete components.
[0006] Technical solution: A concrete curing device for building construction according to the present invention includes a frame. Sliders are slidably connected to both sides of the top of the frame. A spraying assembly for spraying a curing medium is provided between the two sliders. A driving assembly for driving the spraying assembly to reciprocate between the two ends of the frame is provided in the middle of the spraying assembly. When the spraying assembly moves to one end of the frame, the spraying direction of the curing medium is reversely changed. An elevating assembly is provided on the spraying assembly, and a sensing assembly for sensing the dry and wet state of the concrete surface is provided at the lower end of the elevating assembly. The sensing assembly is arranged below the spraying assembly and is electrically connected to the spraying assembly to control the spraying assembly to spray the curing medium on the dry concrete surface.
[0007] The present invention uses the color difference of concrete under different humidity conditions to judge whether the surface of the concrete member needs to be sprayed with water for humidification. Selective spraying is carried out on the local parts that need humidification and spraying, and no spraying is carried out on the local parts with qualified humidity. It can not only monitor and dynamically adjust the surface humidity of the concrete member in real time, improve the curing quality, but also greatly improve the utilization rate of water resources.
[0008] Preferably, the spraying assembly includes an outer pipe arranged between the two sliders. Both ends of the outer pipe are closed. A number of nozzles are communicated with both sides of the outer pipe. Solenoid valves are provided on the nozzles. An inner pipe is slidably connected inside the outer pipe. Both ends of the inner pipe are freely open. A number of side holes are provided on both sides of the inner pipe. When the outer pipe moves to one end of the frame, the inner pipe slides relative to the outer pipe, so that the side holes communicated with the nozzles are changed from one side of the inner pipe to the other side. A water inlet pipe is provided on the outer pipe, and a connection hole corresponding to the water inlet pipe is provided on the inner pipe.
[0009] If the spraying area is in front of the moving direction of the sensing assembly, it will cause the sensing assembly to turn on the nozzles in the dry area, and the area in front of it will immediately become a wet area. The sensing assembly will immediately control the nozzles to close after entering the wet area, resulting in frequent interruption of the spraying operation, affecting the uniformity of spraying, and also reducing the service life of the solenoid valve. To avoid this phenomenon, it is necessary to always keep the spraying area of the nozzles behind the moving direction of the sensing assembly, so that the sensing is in front and the spraying is behind, making the spraying operation continuous and uniform. Since the sensing assembly reciprocates between the two ends of the frame, the moving direction of the sensing assembly will reverse after reaching one end of the frame. To always maintain the principle of sensing in front and spraying behind, the spraying direction of the nozzles also needs to reverse near the end of the frame. Therefore, the present invention adopts a design in which the side holes on both sides of the inner pipe are alternately communicated with the nozzles on both sides of the outer pipe to achieve the purpose of reversing the relative position of the spraying area near the end of the frame.
[0010] Preferably, push bars that are hermetically and slidably connected to the ends of the outer tube are provided at both ends of the inner tube. Rollers are provided at the outer ends of the push bars. One wedge block is provided on each side of the frame, and the two wedge blocks are respectively disposed inside both ends of the frame. When the outer tube moves to one end of the frame, only one of the wedge blocks abuts against the roller.
[0011] In the present invention, the inner tube is forced to slide relative to the outer tube by the wedge blocks, thereby realizing the alternate communication of the side holes on both sides of the inner tube with the nozzles on both sides of the outer tube.
[0012] Preferably, a screw rod and a motor for driving the screw rod to rotate are provided on the frame. The two ends of the screw rod are respectively rotatably connected to both ends of the frame. An installation block fixedly connected to the middle of the outer tube is threadedly connected to the screw rod, and the lifting assembly is provided on the installation block.
[0013] Preferably, the sensing assembly includes an opaque housing provided at the lower end of the lifting assembly. The housing is disposed parallel to the lower side of the outer tube. A plurality of photosensitive resistors are provided inside the housing. The photosensitive resistors are electrically connected to the solenoid valves directly above them. A red filter is hermetically connected to the bottom of the housing.
[0014] The housing can ensure that the light received by the photosensitive resistors only comes from the reflection of the surface of the concrete member to be sensed below it, avoiding the interference of ambient light on the sensing process. Since the concrete member appears darker cyan-gray after being wet or absorbing water, the light reflected by it is mostly blue light. The drier the concrete, the lighter and whiter its color, and the less the proportion of blue light and the more the proportion of red light in the reflected light. When a red filter is used, blue light can be filtered out and only red light is allowed to pass through. In this way, the light irradiation on the photosensitive resistors can be minimized in the wet area, while the photosensitive resistors can be normally conducted in the dry area, enhancing the difference between the wet area and the dry area. Even when the ambient light is strong, the mis-conduction of the photosensitive resistors in the wet area can be avoided, improving the sensing accuracy.
[0015] Preferably, the lifting assembly includes a lifting frame that is vertically and slidably connected to the installation block. A pin for limiting the lifting frame is provided on the installation block, and the housing is provided at the lower end of the lifting frame.
[0016] The lifting assembly can adjust the appropriate height of the housing and the photosensitive resistors on the surface of the concrete member. If the height is too large, it is easy to cause sensing passivation and it is not easy to accurately distinguish the dry area and the wet area. If the height is too low, it is easy to generate shadows and affect the reflection of light into the housing.
[0017] Preferably, a bracket for fixing the light-shielding material is provided at the top of the frame. When the present invention is used outdoors, it is necessary to avoid the influence of strong sunlight irradiation on the sensing assembly. Therefore, appropriate light shielding is required to ensure that the light intensity is within an appropriate range.
[0018] Preferably, light sources are evenly distributed on the inner walls of the frame. The light sources are used to supplement light to the surface of the concrete member at night, avoiding the influence of insufficient light on the recognition of the dry area.
[0019] Preferably, universal wheels are provided at the bottom end of the frame.
[0020] Beneficial effects: Compared with the prior art, the present invention has the following remarkable advantages:
[0021] The present invention can accurately monitor and sense the local dry and wet conditions on the surface of the concrete member, and only spray and supplement water in real time for the dry area, timely supplement the evaporated water, ensure the overall synchronous maintenance of the concrete member, and avoid the overall quality of the concrete member being affected by local cracking caused by untimely local maintenance. Selectively spraying for moisturizing can also effectively improve the utilization rate of water flow and reduce water resource waste. The structure of the present invention is simple and reliable, with high accuracy of sensing and recognition, without the need for complex image sensing processing equipment and software, and has good application prospects.

Detailed implementation manner
[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings.
[0032] As Figures 1-9 shown, a concrete curing device for building construction includes a frame 1. On both sides of the top of the frame 1, there are sliders 13 slidably connected. Between the two sliders 13, there is an outer tube 4. Both ends of the outer tube 4 are closed. On both sides of the outer tube 4, there are several spray heads 42 communicated. Each spray head 42 is provided with a solenoid valve 421. Inside the outer tube 4, there is an inner tube 5 slidably connected. Both ends of the inner tube 5 are freely open. On both sides of the inner tube 5, there are several side holes 53. A water inlet pipe 41 is provided on the outer tube 4, and a connection hole 54 corresponding to the water inlet pipe 41 is provided on the inner tube 5. At both ends of the inner tube 5, there are push bars 51 sealingly and slidably connected to the ends of the outer tube 4. At the outer ends of the push bars 51, there are rollers 52. On the inner wall of one side of the frame 1, there is a first wedge block 12, and on the inner wall of the other side, there is a second wedge block 14. The first wedge block 12 is located at the proximal end of the frame 1, and the second wedge block 14 is located at the distal end of the frame 1. The first wedge block 12 and the second wedge block 14 are both on the same horizontal plane as the rollers 52 to ensure that when the outer tube 4 is in the end area of the frame 1, one of the rollers 52 can abut against the first wedge block 12 or the second wedge block 14. On the frame 1, there is a screw 2 and a motor 21 for driving the screw 2 to rotate. The two ends of the screw 2 are respectively rotatably connected to the two ends of the frame 1. On the screw 2, there is a mounting block 3 fixedly connected to the middle of the outer tube 4. On the mounting block 3, there is a lifting frame 6 slidably connected vertically. On the mounting block 3, there is a pin 61 for limiting the lifting frame 6. At the lower end of the lifting frame 6, there is a housing 7. The housing 7 is made of light-tight material. The housing 7 is arranged parallel to the outer tube 4 directly below. Inside the housing 7, there are several photoresistors 71. The photoresistors 71 are both electrically connected to the two solenoid valves 421 directly above them. At the bottom of the housing 7, there is a red filter 72 sealingly connected.
[0033] In this embodiment, on the top of the frame 1, there is a bracket 15 for fixing the shading material.
[0034] In this embodiment, light sources 11 are evenly distributed on the inner wall of the frame 1. The light sources 11 can adopt LED light strips, and preferably use soft white light sources 11 with moderate light intensity.
[0035] In this embodiment, universal wheels are provided at the bottom ends of the columns of the frame 1. A rail-type moving solution can also be adopted according to the site and the size of the concrete component.
[0036] Working process and principle:
[0037] Connect the water inlet pipe 41 to a water source, and then place the concrete component to be cured under the frame 1. Adjust the red filter 72 to a position 10-20 cm away from the surface of the concrete component through the lifting frame 6. Turn on the motor 21 and rotate the screw 2 to move the mounting block 3 to one end of the frame 1. At this time, the roller 52 rolls along the inclined surface of the first wedge block 12, and the push bar 51 is pressed into the outer pipe 4 by the first wedge block 12. The push bar 51 pushes the inner pipe 5 and the push bar 51 at the other end of the inner pipe 5 to translate synchronously until a plurality of side holes 53 on the side of the inner pipe 5 close to the motor 21 are all communicated with the nozzle 42 close to the motor 21, and a plurality of side holes 53 on the other side of the inner pipe 5 are all misaligned and closed with the nozzle 42 far from the motor 21. The push bar 51 at the other end of the inner pipe 5 extends to the maximum stroke. Turn off the motor 21, reverse the motor 21 and the screw 2, and move the outer pipe 4 and the cover 7 synchronously to the other end of the frame 1. At this time, the red filter 72 sweeps across the surface of the concrete component. When a local area is dry and white, the red light reflected by the dry area enters the cover 7. After the photosensitive resistor 71 senses the light, its resistance decreases, causing the two solenoid valves 421 directly above the photosensitive resistor 71 to be energized and opened. Since only a plurality of side holes 53 on the side of the inner pipe 5 close to the motor 21 are communicated with the nozzle 42 close to the motor 21, the spraying operation is only carried out on the rear side in the moving direction of the cover 7. When the cover 7 enters a wet area, almost no light can pass through the red filter 72 and enter the cover 7. The resistance of the photosensitive resistor 71 increases in the dark, causing the two solenoid valves 421 directly above the photosensitive resistor 71 to be de-energized and closed, ending the spraying operation. In this way, the dry area and the wet area on the surface of the concrete component can be accurately sensed, and only the nozzle 42 is controlled to spray in the dry area, while no spraying is carried out in the wet area. When the outer pipe 4 moves to the second wedge block 14, the roller 52 on the other side of the inner pipe 5 abuts against the inclined surface of the second wedge block 14. As the outer pipe 4 translates, the push bar 51 on the other side of the inner pipe 5 is pressed into the outer pipe 4, and the inner pipe 5 also translates to the other end until a plurality of side holes 53 on the side of the inner pipe 5 far from the motor 21 are all communicated with the nozzle 42 far from the motor 21, and a plurality of side holes 53 on the side of the inner pipe 5 close to the motor 21 are all misaligned and closed with the nozzle 42 close to the motor 21. In this way, when the outer pipe 4 translates in the reverse direction, it can still ensure that the spraying operation is only carried out on the rear side in the moving direction of the cover 7. The first wedge block 12 and the second wedge block 14 can help the inner pipe 5 to reset unidirectionally and efficiently convert the relative positions of the spraying areas. Reverse the motor 21 and repeat the above process to automatically and repeatedly monitor the surface of the concrete component and automatically spray and replenish water locally. Turn on the light source 11 for supplementary lighting at night or when the light is dim. When operating outdoors at noon on a sunny day, a sunshade net can be covered on the support 15.
