[0002] Due to the erosion of the natural environment, accidental impact loads and design changes, the bearing capacity of concrete columns is insufficient and the concrete piers need to be reinforced.

[0003] When reinforcing concrete columns and piers, it is usually necessary to select formwork and support the formwork on site according to the diameter of the concrete columns and piers, and then pour UHPC, i.e. ultra-high performance concrete. The process of on-site formwork is relatively cumbersome and the same set of formwork is difficult to apply to concrete piers of different diameters and different reinforcement thicknesses, resulting in poor versatility. It is necessary to design and produce multiple sets of formworks of different specifications.

[0069] Example 1

[0070] This embodiment provides a variable diameter casting and curing integrated device for UHPC reinforced circular column piers, referring to Figure 1 and Figure 2 As shown, it includes a supporting bottom mold 1, an inner mold assembly 2, an outer mold assembly 3, a protective mold assembly 4 and a driving assembly 5. The supporting bottom mold 1 is a circular ring structure and is sleeved on the outside of the column pier. Specifically, it can be made of multiple sub-plates spliced ​​end to end, which is convenient for assembly outside the column pier. Figure 5 As shown, a first groove 11 extending in the radial direction is provided on the top of the supporting bottom mold 1. Splicing ends 13 are respectively provided at the head and tail ends of each sub-plate body of the supporting bottom mold 1, and the splicing ends 13 are used to splice and then screw-lock.

[0071] Specifically, continue to refer to Figure 1 and Figure 2As shown, the inner mold assembly 2 is located above the supporting bottom mold 1. The inner mold assembly 2 includes a plurality of first plates 21 arranged in a circular ring shape, a first moving rod 22 is inserted in the first plate 21, and both ends of the first moving rod 22 extend to the outside of both ends of the first body respectively, the first moving rod 22 is inserted into the first groove 11 and moves along the length direction of the first groove 11, that is, the first plate 21 is located above the supporting bottom mold 1 and can move relative to the supporting bottom mold 1 in the radial direction. Two adjacent first plates 21 are connected by a first extendable structure 23, which expands and contracts with the movement of the first plate 21. When the first plate 21 moves in the radial direction, the diameter of the inner mold assembly 2 will increase or decrease, and the first extendable structure 23 will expand and contract accordingly so that the interior of the inner mold assembly 2 is always surrounded by a circumferentially closed first cavity 24. A casting space is formed between the first cavity 24 and the pier. The diameter of the first cavity 24 is adjusted by moving the first moving rod 22, so that it can adapt to piers of different diameters and can be adjusted to the required reinforcement thickness.

[0072] In order to facilitate the assembly of the inner mold assembly 2 on the column pier, the inner mold assembly 2 can be divided into multiple parts and assembled when in use. Figure 4 As shown, in this embodiment, the first extendable structure 23 includes two first substructures spliced ​​to each other, which are separated by the center line of the first extendable structure 23 to divide the inner mold assembly 2 into four parts, and the inner mold assembly 2 is spliced ​​into a whole by assembling the two first substructures of the first extendable structure 23.

[0073] Specifically, continue to refer to Figure 1-2 As shown, the outer mold assembly 3 is located above the supporting bottom mold 1 and surrounds the outer side of the inner mold assembly 2. The outer mold assembly 3 includes a plurality of second plates 31 arranged in a circular ring; a second moving rod 32 is inserted into the second plate 31, that is, the two ends of the second moving rod 32 also extend outward from the two ends of the second plate 31. The second moving rod 32 is inserted into the first groove 11 and moves along the length direction of the first groove 11; that is, the second plate 31 is located above the supporting bottom mold 1 and can move relative to the supporting bottom mold 1 in the radial direction. Adjacent second plates 31 are connected by a second extendable structure 33, and the second extendable structure 33 expands and contracts with the movement of the second plate 31. When the second plate 31 moves in the radial direction, the diameter of the outer mold assembly 3 will increase or decrease, and the second extendable structure 33 expands and contracts accordingly so that the interior of the outer mold assembly 3 is always surrounded by a circumferentially closed second cavity 34. The second cavity 34 serves as a storage space for curing water or curing steam. When the first cavity 24 is adjusted due to the diameter of the pier or the reinforcement thickness, the thickness of the second cavity 34 is also adjusted by moving the second moving rod 32 to ensure that there is enough storage space for the curing water or curing steam.

[0074] In order to facilitate the assembly of the outer mold assembly 3 outside the inner mold assembly 2, the outer mold assembly 3 can also be divided into multiple parts and assembled when in use. Figure 4 As shown, in this embodiment, the second extendable structure 33 includes two second sub-structures spliced ​​to each other, which are separated by the center line of the second extendable structure 33 to divide the outer mold assembly 3 into four parts, and the outer mold assembly 3 is spliced ​​into a whole by assembling the two second sub-structures of the second extendable structure 33.

[0075] Specifically, the mold protection component 4 surrounds the outer side of the outer mold component 3, provides certain protection for the inner mold component 2 and the outer mold component 3, and provides an installation position for the driving component 5. Accordingly, the mold protection component 4 is also composed of four parts spliced ​​together, which is convenient for the mold protection component 4 to be installed on the outer side of the outer mold component 3.

[0076] Specifically, the driving assembly 5 is installed on the mold protection assembly 4 and connected to the first moving rod 22 or the second moving rod 32 to drive the first moving rod 22 or the second moving rod 32 to move along the length direction of the first groove 11 .

[0077] The variable diameter casting and curing integrated device for UHPC reinforced circular piers provided in this embodiment can adjust the diameters of the inner mold assembly 2 and the outer mold assembly 3 to adapt to piers of different diameters and different reinforcement thicknesses, and has strong versatility; and the casting formwork and the curing structure are integrated and can be installed as a whole, with high construction efficiency, and the concrete can be cured without removing the formwork, and the curing effect is good.

[0078] Specifically, continue to refer to Figure 1-2 As shown, the driving assembly 5 includes a driving motor 51, a driving gear 52, a first transmission assembly and a second transmission assembly. A motor mounting seat 41 is provided on the side of the mold guard assembly 4, and the driving motor 51 is installed on the motor mounting seat 41 outside the mold guard assembly 4. A gear mounting seat 42 is provided on the top of the mold guard assembly 4, and the driving gear 52 is rotatably mounted on the gear mounting seat 42 on the top of the mold guard assembly 4, so that the driving gear 52 is connected to the driving motor 51 in a transmission manner, and the driving motor 51 drives the driving gear 52 to rotate. The corresponding driving gear 52 is also divided into four sub-gears, and the four sub-gears are spliced ​​end to end to form a completed driving gear 52.

[0079] Reference Figure 6As shown, the first transmission assembly includes a first transmission ring 53 and a first arc-shaped control handle 54; one end of the first arc-shaped control handle 54 is hinged to the first transmission ring 53, and the other end is hinged to the first moving rod 22. The second transmission assembly includes a second transmission ring 55 and a second arc-shaped control handle 56; one end of the second arc-shaped control handle 56 is hinged to the second transmission ring 55, and the other end is hinged to the second moving rod 32. The driving gear 52 is connected to the first transmission ring 53 or the second transmission ring 55, and is used to drive the first transmission ring 53 or the second transmission ring 55 to rotate. The corresponding first transmission ring 53 and the second transmission ring 55 are respectively assembled from four parts, which is easy to install.

[0080] In this embodiment, the following three situations can be divided, namely, the driving gear 52 is connected only to the first transmission ring 53, or the driving gear 52 is connected only to the second transmission ring 55, or the driving gear 52 is connected to both the first transmission ring 53 and the second transmission ring 55. When the driving gear 52 is connected only to the first transmission ring 53, when the driving gear 52 drives the first transmission ring 53 to rotate, the first moving rod 22 can only move along the length direction of the first groove 11 under the restriction of the first groove 11, so that the first arc-shaped control handle 54 drives the first moving rod 22 to move along the length direction of the first groove 11, thereby increasing or reducing the diameter of the inner mold assembly 2. Accordingly, according to the connection mode of the driving gear 52 with the first transmission ring 53 and the second transmission ring 55, the rotation of the driving gear 52 can respectively realize the synchronous adjustment or separate adjustment of the diameters of the inner mold assembly 2 and the outer mold assembly 3.

[0081] Reference Figure 8 As shown, the driving gear 52, the first transmission ring 53, and the second transmission ring 55 are coaxially arranged and arranged from bottom to top along the vertical direction.

[0082] Specifically, refer to Figure 7 As shown, the mold guard assembly 4 includes a side guard plate 43 and a top end plate 44, a gear mounting seat 42 is formed between the side guard plate 43 and the top end plate 44, and an annular groove 45 is provided on the top end plate 44; the top surface end plate is located above the inner mold assembly 2 and the outer mold assembly 3, and covers the second cavity 34, so that the annular groove 45 is located between the first moving rod 22 and the second moving rod 32.

[0083] Reference Fig. 9As shown, the first transmission ring 53 is provided with a first connecting ear 531, the first connecting ear 531 is provided with a first connecting rod 532, one end of the first connecting rod 532 is rotatably connected to a first pulley 533, and the other end is hinged to a first arc-shaped control handle 54, and the first pulley 533 is rollingly arranged in the annular slide groove 45. The first transmission ring 53 is supported by the first connecting rod 532, and the annular slide groove 45 limits the rotation of the first transmission ring 53.

[0084] Correspondingly, a second connecting ear 551 is provided on the second transmission ring 55, and a second connecting rod 552 is provided on the second connecting ear 551. One end of the second connecting rod 552 is rotatably connected to a second pulley 553, and the other end is hinged to the second arc-shaped control handle 56. The second pulley 553 is rollingly arranged in the annular groove 45.

[0085] Continue to refer to Figure 8 As shown, the first transmission ring 53 is connected to a first telescopic rod, and the driving gear 52 is provided with a first plug hole; the first telescopic rod is inserted into the first plug hole when extended, and is disengaged from the first plug hole when shortened. The second transmission ring 55 is connected to a second telescopic rod 57, and the driving gear 52 is provided with a second plug hole 58; the second telescopic rod 57 is inserted into the second plug hole 58 when extended, and is disengaged from the second plug hole 58 when shortened.

The first rod body 571 is provided with a first positioning hole, and the second rod body 572 is provided with at least two second positioning holes extending in the vertical direction. The second rod body 572 is movably inserted into the first rod body 571. The first rod body 571 and the second rod body 572 are relatively fixed by inserting the latch 573 into the first positioning hole and the second positioning hole. When the latch 573 is inserted into different second positioning holes, the second telescopic rod 57 can maintain different lengths. When the second telescopic rod 57 is extended, the first rod body 571 and the second rod body 572 are fixed by the latch 573, and the second rod body 572 is inserted into the second plug hole 58 to realize the connection between the second transmission ring 55 and the driving gear 52; when the second telescopic rod 57 is shortened, the first rod body 571 and the second rod body 572 are fixed by the latch 573, so that the second rod body 572 is separated from the first plug hole, so that the second transmission ring 55 and the driving gear 52 are no longer connected.

[0087] Correspondingly, the structure of the first telescopic rod is the same as that of the second telescopic rod 57 , and thus will not be described in detail.

[0088] Specifically, continue to refer to Figure 6As shown, the top end plate 44 is provided with a through slot 46 aligned with the first channel 11. The first moving rod 22 and the second moving rod 32 pass through the through slot 46 and then extend outward.

[0090] Specifically, during the pouring process, in order to prevent the driving gear 52 from rotating and affecting the inner mold assembly 2 and the outer mold assembly 3, refer to Fig.16 As shown, a gear brake buckle 35 is hinged on the side guard plate 43. When the driving gear 52 needs to be rotated, the gear brake buckle 35 is rotated to disengage the gear groove; when the driving gear 52 needs to be fixed before pouring, the gear brake buckle 35 is rotated to be stuck in the gear groove, thereby limiting the rotation of the driving gear 52.

[0091] The first extended structure 23 can be implemented in a variety of different structural forms. Fig.10 As shown, the first extended structure 23 includes a moving plate 25; a plug-in plate 26 is provided on the side of the moving plate 25, and a plug-in slot 27 is provided on the side of the first plate body 21; the plug-in plate 26 is inserted into the plug-in slot 27, so that when the first plate body 21 moves, the plug-in plate 26 moves relative to the plug-in slot 27. In other embodiments, the first extended structure 23 can also be implemented by a corrugated plate structure.

[0092] Specifically, refer to Fig.15 As shown, in order to ensure that the first plate body 21 and the movable plate 25 can move relative to each other smoothly, rollers 29 and track structures can be respectively provided in the plug-in plate 26 and the plug-in slot 27 with reference to the figure.

[0093] Specifically, in order to allow the first plate body 21 and the movable plate 25 to move accordingly when the diameter of the inner mold assembly 2 changes, a flexible material can be used to make the plug-in plate 26 so that the plug-in plate 26 has a certain elastic deformation ability, so that when the first body and the movable plate 25 move relative to each other, the plug-in plate 26 undergoes a certain degree of deformation to adapt to the change in diameter.

[0094] Specifically, a second groove 12 is further provided at the bottom of the supporting bottom mold 1 , and a rod inserted into the second groove 12 is provided at the bottom of the movable plate 25 to guide and position the moving direction of the movable plate 25 .

[0095] Correspondingly, the second extendable structure 33 may adopt the same structural form as the first extendable structure 23 , which will not be described in detail in this embodiment.

[0096] Specifically, refer to Fig.11 As shown, a partition plate 6 is connected between the inner mold assembly 2 and the outer mold assembly 3, and the partition plate 6 separates the second cavity 34; the partition plate 6 includes a third plate body 61 and a fourth plate body 62 that are plugged into each other. That is, the third plate body 61 is connected to the first extension structure 23, and the fourth plate body 62 is connected to the second extension structure 33. When the inner mold assembly 2 and the outer mold assembly 3 move relative to each other and the diameter difference thereof changes, the third plate body 61 and the fourth plate body 62 can move relative to each other and adapt thereto.

[0097] Specifically, the first plate 21 is provided with a through hole extending in the vertical direction. Fig.14 As shown, the maintenance hole 28 is arranged on the first plate 21 and passes through the through hole; the first moving rod 22 is rotatably inserted into the through hole, referring to Fig.13 As shown, the first moving rod 22 is provided with a switching hole 221, and the first moving rod 22 is rotated to disconnect or connect the switching hole 221 with the maintenance via 28. When the first moving rod 22 is rotated to align the switching hole 221 with the maintenance via 28, the maintenance via 28 is in a conducting state; when the first moving rod 22 is rotated to stagger the switching hole 221 with the maintenance process, the maintenance via 28 is in a disconnected state, so that the flow state of the medium between the first cavity 24 and the second cavity 34 can be controlled.

[0098] Specifically, refer to Figure 6 As shown, the top of the first moving rod 22 is provided with an indicator block 222 for marking the extending direction of the switching hole 221. The extending direction of the switching hole 221 is marked by the indicator block 222, so as to facilitate the judgment of the on-off state between the switching hole 221 and the maintenance via 28.

[0099] Continue to refer to Fig.13 and Fig.14 As shown, in order to ensure that the first moving rod 22 moves smoothly in the first groove 11, a first rolling wheel 223 is rotatably connected to the bottom of the first moving rod 22, so that the first rolling wheel 223 is rollingly located in the first groove 11 to reduce the resistance of movement. Correspondingly, a second rolling wheel is also rotatably connected to the bottom of the second moving rod 32 to assist the movement of the second moving rod 32.

[0100] Specifically, continue to refer to Fig.12 As shown, a water heater 7 is also installed at the bottom of the second plate body 31, and the curing water can be heated by the water heater 7, so as to control the temperature of the curing water and improve the curing effect.

[0101] Example 2

[0102] This embodiment provides a method for using the integrated pouring and curing device described in Embodiment 1, referring to Fig.17 As shown, the following steps are included:

[0103] S1. Install the template;

[0104] S2. Drain the water in the pouring space

[0105] S3, pouring concrete into the pouring space;

[0106] S4, maintenance;

[0107] S5. After the concrete is cured to the predetermined strength, the formwork is removed.

[0108] It should be noted that, in this embodiment, the concrete poured into the pouring space is ultra-high performance concrete.

[0109] Specifically, the process of installing the formwork in step S1 includes: first assembling the integrated maintenance device into four parts according to the diameter of the pier, and then assembling the four parts around the outside of the pier to form a whole, so that a casting space is formed between the inner mold assembly 2 and the circular pier. After the assembly is completed, the first moving rod 22 or the second moving rod 32 is driven by the driving assembly 5 to move, adjust the diameter of the inner mold assembly 2 and the protective mold assembly 4, and control the thickness of the casting space. Through the above installation process, the integrated casting and maintenance device can adapt to piers of different diameters and can adjust the thickness of the reinforcement.

[0110] Specifically, the process of draining the accumulated water in the casting space in step S2 includes: switching the open-close structure state to make the maintenance via 28 conductive, using the driving assembly 5 to drive the first moving rod 22 to move in the direction close to the pier, so that the diameter of the inner mold assembly 2 is reduced, so that the accumulated water in the casting space flows into the second cavity 34 through the maintenance via 28 until the accumulated water is drained; switching the open-close structure state to close the maintenance via 28, using the driving assembly 5 to drive the first moving rod 22 to move in the direction away from the pier, until the casting space reaches a predetermined thickness. When reinforcing underwater piers, draining the accumulated water in the casting space through the above steps can better perform casting and avoid the influence of accumulated water on the casting process.

[0111] Specifically, the curing process in step S4 includes: using the driving assembly 5 to drive the first moving rod 22 to move in a direction away from the column pier, so that a gap is formed between the inner mold assembly 2 and the poured concrete; switching the open and close structure state to make the curing through hole 28 conductive, and injecting curing water or steam into the gap; switching the open and close structure state to close the curing through hole 28, driving the first moving rod 22 to move in a direction close to the column pier, so that the inner mold assembly 2 squeezes the curing water or steam. By driving the inner mold assembly 2 to squeeze the curing water or steam, the curing water or steam can be more fully contacted with the concrete, thereby improving the curing effect.

[0112] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0113] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
