Abstract
Description
Technical Field
[0001] The invention relates to the technical field of concrete curing, in particular to a highway construction concrete curing method. Background Art
[0002] In the process of highway construction, a lot of concrete is needed, and the concrete is made into concrete components. The concrete components are placed in a curing box and the temperature control components are used to artificially create the corresponding temperature and humidity for the concrete components to cure the concrete components and improve the quality after construction; Existing concrete curing boxes are mostly composed of a box body, a multi-layer placement plate that slides inside, and a control component for heating and humidification arranged inside the box body. The sliding of the placement plate and the box body is generally completed by a guide rail, and then the placement and removal of the concrete component are completed by pulling out the placement plate. In actual use, the volume of the concrete component is large. In the traditional method of pulling out the placement plate, the placement plate needs to be pulled outward to the limit during the lifting and placing of the component. At this time, only a very small part of the placement plate is inside the slide rail, and the overall bearing capacity of the placement plate will be weakened. When the component is placed on the placement plate, it will impact the placement plate, which is easy to cause the placement plate to tilt due to increased fatigue strength after multiple stresses, which makes it easy for the placement plate to slide outward (the concrete component will slide easily due to humidification during the curing process), and the placement position of the concrete curing box may not be horizontal, which will increase the possibility of the concrete component sliding outward, thereby causing safety hazards, and in the subsequent pulling and pulling process of the placement plate, it will not overlap with the track and cannot slide smoothly.

[0018] See also Figure 1-Figure 11 , the present invention provides a technical solution: A method for curing highway construction concrete, the method comprising the following steps: Step 1: Place the concrete components on the curing device one by one; Step 2: During the placement of the concrete component, the curing device can buffer the impact force and gravity generated by the placement of the concrete component; Step 3: After the concrete component is placed, the curing device can adjust the placement position of the concrete component outward to facilitate subsequent lifting; Step 4: When taking out the concrete component, the curing device can overcome the tendency of the concrete component to actively slide inwards and outwards due to the uneven placement of the curing device, so as to facilitate lifting; The curing device in step 1, step 2, step 3 and step 4 comprises a shell 1 and a plurality of support groups located inside the shell 1, the support groups are spaced apart in the vertical direction, and a temperature control component for adjusting the temperature and dryness and humidity of the concrete component is arranged inside the shell 1; The support group includes a placement frame 2, a support frame 7 is arranged inside the placement frame 2, and a plurality of rollers 3 are rotatably connected to the inner wall of the support frame 7. The support frame 7 is gradually inclined from back to front, and the positions of the plurality of rollers 3 are gradually increased from back to front. The placement frame 2 is slidably connected to the shell body 1, and a first cylinder 10 is fixedly connected between the placement frame 2 and the inner wall of the shell body 1. A first support rod 4 is rotatably connected to the side wall of the placement frame 2, and a second support rod 5 is slidably connected to the first support rod 4. The second support rod 5 is rotatably connected to the side wall of the shell body 1. A baffle 6 is arranged on the side wall of the placement frame 2, and an adjustment plate 8 is arranged above the support frame 7. The adjustment plate 8 is slidably connected to the left and right side walls of the support frame 7 in the front-to-back direction. A locking group is arranged on one side of the adjustment plate 8, and the locking group is used to lock and release the adjustment plate 8. A push rod 9 is arranged behind the adjustment plate 8, and the push rod 9 is arranged on the inner wall of the shell body 1.
[0019] like Figure 1-Figure 4 As shown: The figure shows the state after the concrete component is placed inside the shell 1. At this time, the concrete component is above the roller 3. Then the shell 1 can be used to maintain the internal concrete component. After the maintenance is completed, the concrete component can be taken out. Placement of concrete elements: Before placing the concrete component, one of the multiple placement frames 2 is first pushed to move the placement frame 2 and the support frame 7 outward to the limit by extending the first cylinder 10. When the placement frame 2 moves outward, the first support rod 4 will slide outward inside the second support rod 5 (when the placement frame 2 is inside the shell 1, the first support rod 4 is inside the second support rod 5). After the placement frame 2 slides outward to the limit, the first support rod 4 and the second support rod 5 will form an inclined support for the position of the placement frame 2 near the front end, thereby protecting the impact and large load generated when placing the concrete component in the subsequent time, so as to avoid the deformation (tilting) of the placement frame 2 due to stress concentration, which makes it impossible to cooperate with the guide rail in the shell 1, and the potential safety hazard caused by the concrete component sliding outward after tilting; The concrete component is hoisted by a crane (a hook is provided above the concrete component) to the top of the placement plate 2, and then slowly moved down to the top of the roller 3 on the support frame 7. The front end of the support frame 7 is higher than the rear end, so that the concrete component will not slide outwards and tilt after being on the roller 3, and the sliding of the concrete component caused by the forward tilting of the shell 1 due to the uneven ground height can be overcome, thereby further reducing safety hazards; After the concrete component is placed on the roller 3, and when the lifting rope is disassembled, the concrete component will slide toward the rear of the shell 1 when the support frame 7 and the roller 3 are uneven in height. Then, the first cylinder 10 can be controlled to shorten to make the placement frame 2 and the support frame 7 move toward the inside of the shell 1, and the adjustment plate 8 is located behind the support frame 7. On the one hand, it can block the concrete component from sliding backwards to the maximum extent when the concrete component slides backwards due to the inconsistent front and rear heights of the support frame 7. On the other hand, when the support frame 7 and the placement frame 2 move toward the inside of the shell 1, they will be blocked by the stationary push rod 9. At this time, the push rod 9 will give the adjustment plate 8 a forward push during the backward movement of the adjustment plate 8. Then, the adjustment plate 8 will slide forward along the support frame 7 when the support frame 7 and the placement frame 2 move backwards. At this time, the adjustment plate 8 will push the concrete component above the roller 3 to move toward the direction close to the baffle 6, so that the subsequent concrete component can be located near the front instead of the rear when it is taken out, so as to facilitate the lifting. When the first cylinder 10 is shortened to the limit, the adjustment plate 8 will push the concrete member to a position close to the baffle 6. At this time, the position of the concrete member is at a front position on the support frame 7, and the locking group will lock the adjustment plate 8 when the adjustment plate 8 does not slide forward along the support frame 7. At this time, the side wall of the baffle 6 will also fit with the side wall of the shell 1 to complete the sealing of the inside of the shell 1. Then, the concrete can be placed in the remaining placement frames 2 in the above manner. After the placement is completed, the concrete components can be cured and taken out after the curing work is completed. Removal of concrete components: Start the first cylinder 10. The extension of the first cylinder 10 will push the placement frame 2 to slide outward from the inside of the shell 1. At this time, the baffle 6 will also follow the placement frame 2 and move outward together with the support frame 7. At this time, the concrete component will move outward. Because the adjustment plate 8 is now located above the support frame 7 and has been fixed by the locking group, the adjustment plate 8 will follow the support frame 7 during the movement of the placement frame 2 and will not be pushed backward when the concrete component is lowered due to the rear end of the support frame 7, thereby preventing the concrete component from shifting backward. When the placement frame 2 moves outward, the first support rod 4 and the second support rod 5 will gradually slide and expand. When the placement frame 2 moves outward to the limit, the first support rod 4 and the second support rod 5 will no longer be able to slide. At this time, the side wall of the placement frame 2 will be supported to increase the bearing capacity of the placement frame 2. Then the concrete component can be lifted out by the crane. After the concrete component is lifted out, the gravity applied by the concrete component to the support frame 7 and the roller 3 disappears. At this time, the locking group will actively drive the adjustment plate 8 to reset. The first support rod 4 and the second support rod 5 can continuously provide support for the placement plate 2 during the period of lifting out by the crane and the subsequent placement of the concrete component to prevent the placement frame 2 from deforming until the concrete component is lifted out and a new concrete component is placed. In the present invention, when the concrete component is placed on the placement frame 2 and the concrete component is suspended from the placement frame 2, the first support rod 4 and the second support rod 5 can be automatically unfolded to provide an oblique support for the position near the front end of the placement frame 2, thereby increasing the bearing capacity of the placement frame 2, so that the placement frame 2 will not be easily deformed under the gravity of the concrete component; Moreover, when the concrete component is placed and the placement frame 2 moves toward the inside of the shell 1, the adjustment plate 8 and the push rod 9 can cooperate to automatically adjust the placement position of the concrete component forward under the condition that the placement surface of the placement plate 2 is large to facilitate placement, thereby relatively reducing the space of the placement surface of the placement frame 2, so that the concrete component can be placed in a position close to the front, so that it can be easily lifted out when it is lifted out later, reducing the position interval and time required for manual work and the crane to align and adjust with the hook; By setting the front and rear ends of the support frame 7 to be inconsistent in height, the concrete component can be actively slid backward during the placement of the concrete component, so that the concrete component will not be in the forward position for a long time, and the possibility of the concrete component sliding forward due to inconsistent ground height is overcome, and the duration of the overall center deviation of the shell 1 is reduced. Under the cooperation of the adjustment plate 8 and the locking group, the concrete component can be blocked by fixing the position of the adjustment plate 8 after the placement frame 2 slides out, so as to avoid the concrete component sliding backward when it is hoisted out.
[0020] The locking group includes several first springs 11, two second springs 12 and a one-way gear 13. The support frame 7 and the placement frame 2 are slidably connected in the vertical direction. Several first springs 11 are fixedly connected between the support frame 7 and the inner wall of the placement frame 2. The one-way gear 13 is rotatably connected to the adjustment plate 8 near the bottom end. The second springs 12 are fixedly connected between the adjustment plate 8 and the inner wall of the support frame 7. A first rack rod 14 is meshed below the one-way gear 13, and the first rack rod 14 is fixedly connected to the inner wall of the placement frame 2.
[0021] like Figure 5-Figure 7 As shown: When the concrete component is hoisted onto placement frame 2: Before this, the support frame 7 and the placement frame 2 will be moved outward to the extreme position. At this time, the support frame 7 is not pressed down by the concrete component, so at this time, the support frame 7 is at a slightly higher position under the elastic relaxation of the first spring 11, and the adjustment plate 8 is also at the rear of the support frame 7 under the restriction of the second spring 12. When the concrete component is placed on the roller 3, the support frame 7 will be pressed down. At this time, the first spring 11 will be compressed to the extreme extent. At this time, the support frame 7 will slide down along the placement frame 2 to the extreme extent. At this time, the one-way gear 13 will drop to a position where it can contact the first rack rod 14. When the front and rear heights of the support frame 7 are inconsistent, the concrete component will slide backwards. The maximum distance of the sliding is to slide to the adjustment plate 8 side wall contact position, can also be less than this distance, then the first cylinder 10 can be shortened to drive the placement frame 2 and the support frame 7 to move into the shell 1, and when the adjustment plate 8 moves backward to the position of contact with the push rod 9, it will be pushed forward by the push rod 9, and the adjustment plate 8 will slide forward along the support frame 7 and stretch the second spring 12, and the one-way gear 13 will rotate along the first rack rod 14 and keep meshing, and the adjustment plate 8 will push the concrete component to move along the roller 3 toward the baffle 6, so that the concrete component is positioned forward for easy removal in the subsequent removal, and when the first cylinder 10 is shortened to the limit, the side wall of the baffle 6 is in contact with the side wall of the shell 1 to complete the sealing, and then the maintenance work can be started; When the concrete component is removed from the placement frame 2: The first cylinder 10 is extended to move the placement frame 2 and the support frame 7 outward. In the process of the placement frame 2 moving forward, the adjustment plate 8 is disengaged from the push rod 9, and the second spring 12 tends to pull the adjustment plate 8 to slide backward, but the one-way gear 13 cannot rotate at this time, and is then blocked by the first rack rod 14 to prevent the concrete component from sliding backward. After the concrete component is hung down, the support frame 7 is no longer pressed down by the gravity of the concrete component. At this time, the first spring 11 will drive the support frame 7 to slide up along the placement frame 2, and the one-way gear 13 will be disengaged from the first rack rod 14, and then the second spring 12 will drive the adjustment plate 8 to reset, thereby placing the adjustment plate 8 at the rear.
[0022] The baffle plate 6 is rotatably connected to the placement frame 2, and a resisting end 15 is provided at the front end of the baffle plate 6. The top end of the placement frame 2 is rotatably connected to a retractable gear 16 at a position inside the shell 1. A pull rope 17 is fixedly connected to the rotating shaft of the retractable gear 16. The other end of the pull rope 17 is fixedly connected to the side wall of the baffle plate 6. A clamping rod 18 is meshed at the rear of the retractable gear 16. A tooth groove that can mesh with the teeth of the retractable gear 16 is provided on the clamping rod 18. The clamping rod 18 is slidably connected to a transverse groove 19, which is provided on the inner side wall of the shell 1. A third spring 20 is fixedly connected between the transverse groove 19 and the rear end of the clamping rod 18. A second rack rod 21 is provided in front of the retractable gear 16, and the second rack rod 21 is fixedly connected to the inner side wall of the shell 1. A sealing group is arranged above the baffle 6 .
[0023] The sealing group includes a sealing member 22 , which is fixedly connected to the housing 1 and is in contact with the baffle 6 .
[0024] like Figure 2-Figure 4 as well as Figure 7 As shown: When the placement frame 2 and the support frame 7 are located inside the shell 1, that is, when the shell 1 is curing the concrete component, the side wall of the baffle 6 is in contact with the side wall of the shell 1, and the tooth groove of the clamping rod 18 is meshed with the retracting gear 16, and the third spring 20 is compressed to the limit, and the clamping rod 18 is at the rear of the transverse groove 19. When the curing is completed, the placement frame 2 and the support frame 7 need to be moved outward to remove the cured concrete component; At this time, the first cylinder 10 extends to push the placement frame 2 to slide outward along the shell 1. At this time, the baffle 6 will move forward together with the pull rope 17, and the baffle 6 is in an inclined state. When the retracting gear 16 moves forward, the card rod 18 will push the card rod 18 to move along the transverse groove 19 under the elastic reset action of the third spring 20. During this process, the card rod 18 always keeps the restriction on the retracting gear 16. After the card rod 18 moves to the front of the transverse groove 19, the third spring 20 will no longer be compressed, and the card rod 18 will stay at this position, while the placement frame 2 continues to carry The automatic retractable gear 16 moves forward, at which time the retractable gear 16 will be disengaged from the clamping rod 18, and then the retractable gear 16 will contact and mesh with the second rack rod 21. In the process of the placement frame 2 moving forward, the retractable gear 16 will rotate and unwind the pull rope 17 that has been wound on its rotation axis, and then the baffle 6 can be manually pulled outward to disengage the baffle 6 from the resisting end 15, and rotate forward from the inclined state to the state with the top facing downward, so that the baffle 6 will rotate downward when the concrete component is subsequently lifted and placed, thereby facilitating the lifting and placing work; When the concrete is placed, it is necessary to move the placement frame 2 and the support frame 7 toward the inside of the shell 1. At this time, the first cylinder 10 needs to be shortened, so the placement frame 2 will move toward the inside of the shell 1. At this time, the retracting gear 16 will continue to mesh with the second rack rod 21 to reel in the pull rope 17. At this time, the pull rope 17 will drive the baffle 6 to gradually rotate upward from the inclined state with the top facing downward. After the retracting gear 16 is disengaged from the second rack rod 21, the baffle 6 will rotate to a position in contact with the resisting end 15. At this time, the baffle 6 will stay in an inclined state, and then the placement frame 2 continues to move backward to make the retracting gear 16 contact with the clamping rod 18. At this time, the clamping rod 18 will restrict the retracting gear 16, and then the retracting gear 16 continues to move backward to push the clamping rod 18 to slide along the transverse groove 19 and compress the third spring 20 until the side wall of the baffle 6 fits with the sealing member 22 to complete the sealing.
[0025] The side walls of the baffle 6 are fixedly connected with positioning rods 23 , and a positioning groove 24 is formed at a position on the inner side of the housing 1 corresponding to the positioning rods 23 .
[0026] like Figure 2 , Figure 3 as well as Fig. 9 and Fig.10 As shown: When the baffle 6 contacts the resisting end 15, it will be in a tilted state, but at this time the positioning rod 23 is in a horizontal state, and as the placement frame 2 moves, the positioning rod 23 will directly enter the interior of the positioning groove 24, and at this time, the baffle 6 can be restricted so that the baffle 6 will not easily shake or loosen; In addition, after the placement frame 2 moves backward to the adjustment plate 8 and contacts the push rod 9, the push rod 9 will push the adjustment plate 8 forward to push the concrete component forward to facilitate the subsequent lifting of the concrete component. When the concrete component is placed on the placement frame 2, the position may be offset, that is, the front and rear ends may be tilted, which may easily cause the adjustment plate 8 to push the concrete component to contact the baffle 6 before the baffle 6 contacts the shell 1 and the seal 22. Under this relatively large driving force, the pull rope 17 may be loosened, causing the baffle 6 to rotate, resulting in subsequent The seal is not tight, but through the cooperation of the positioning rod 23 and the positioning groove 24, the positioning rod 23 enters the interior of the positioning groove 24 before the adjustment plate 8 contacts the push rod 9, and the baffle 6 is tilted at this time. Then, if the baffle 6 wants to rotate under the push of the concrete component, it will be blocked by the positioning rod 23 and the positioning groove 24, and the baffle 6 cannot rotate. Then, if the adjustment plate 8 continues to push the concrete component, the inclined concrete component can only be forced to rotate from the inclined state to the horizontal state without affecting the sealing, thereby improving the convenience of being lifted out later.
[0027] The push rod 9 is slidably connected to a driving member 25 , a rear end of the driving member 25 is fixedly connected to a second cylinder 26 , and a fourth spring 27 is fixedly connected between the driving member 25 and the push rod 9 .
[0028] like Figure 3 and Figure 4 As shown: The extension and retraction of the second cylinder 26 can drive the driving member 25 and the push rod 9 forward and backward, thereby increasing or decreasing the distance that the push rod 9 pushes the adjusting plate 8 forward, so that it can adapt to concrete components of different sizes. The setting of the fourth spring 27 can provide a buffer when the adjusting plate 8 pushes the concrete component to contact the baffle 6, so as to avoid excessive direct pushing force causing a large impact on the side wall of the adjusting plate 8 or the baffle 6.
[0029] The end of the push rod 9 is rotatably connected to a roller 28 .
[0030] like Figure 4 As shown: The roller 28 is provided so that the adjustment plate 8 and the push rod 9 do not directly contact each other but contact each other through the roller 28 , which can reduce the friction between the adjustment plate 8 and the push rod 9 when the adjustment plate 8 slides along the support frame 7 in an inclined state.
[0031] The inner wall of the placement frame 2 is provided with a plurality of reinforcing ribs 29 integrally formed with the placement frame 2 , the sliding end of the support frame 7 is located inside the reinforcing ribs 29 , and the first springs 11 are fixedly connected between the reinforcing ribs 29 and the support frame 7 .
[0032] like Figure 7 and Figure 8 As shown: The provided reinforcing ribs 29 can make the support frame 7 slide down along the reinforcing ribs 29 under the action of gravity after the concrete component is placed on the support frame 7 and compress the first spring 11, thereby enhancing the bearing capacity of the support frame 7.
