Description

Technical Field

[0001] The present application relates to the technical field of column pier reinforcement, and in particular to an integrated pouring and curing device and method for column pier outsourcing reinforcement. Background Art

[0002] Due to factors such as erosion from 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] There are various methods for reinforcing piers. One currently proposed reinforcement method is multi-layer, ultra-high performance concrete (UHPC) strips. This method employs multiple vertically arranged strips on the pier's exterior surface, with gaps of a defined thickness between each layer. This reinforcement method exhibits excellent axial compression performance, significantly improving load-bearing capacity, crack resistance, and ductility. In particular, the gaps prevent a continuous cracking pattern, facilitating subsequent repair of each strip layer if damaged.

[0004] This outsourcing reinforcement method for multi-layer strip structural layers arranged at intervals has become a key research direction in this technical field. However, due to the interval arrangement between the strip structural layers, it is usually necessary to set up multiple sets of separated casting templates during construction, and set up grouting structures on the sides of each casting template. This will result in the need to set up a large number of grouting structures, and the side grouting method is less dense than the top grouting method. Setting up the grouting structure on the side of the casting template will also make it impossible to set up a maintenance structure on the side of the casting template. After casting and removing the grouting structure, the maintenance structure needs to be installed, making the construction more cumbersome.

[0029] Embodiment 1 This embodiment provides a pouring and curing integrated device for the external reinforcement of column piers. Refer to Figure 1 and Figure 2As shown, the structure comprises a casting formwork 1 and a partitioning formwork 2, which are arranged alternately along the vertical direction. The casting formwork 1 is used to cast the strip-shaped structural layers, and the partitioning formwork 2 is used to form gaps between adjacent strip-shaped structural layers. The specific number of partitioning formworks can be determined based on the number of strip-shaped structural layers. It should be noted that in this embodiment, the column pier is a rectangular column structure, and the integrated casting and curing device can be configured to a corresponding shape. In other embodiments, the column pier can also be cylindrical or have other shapes.

[0030] Specifically, refer to Fig. 9 As shown, the casting template 1 includes an inner mold 12 and an outer mold 11. The inner mold 12 surrounds the column pier to form a casting space. Since the column pier in this embodiment is a rectangular column structure, the outer contour of the casting space surrounded by the inner mold 12 can also be rectangular. The outer mold 11 surrounds the inner mold 12 to form a preparatory space, and the outer contour of the preparatory space is also a corresponding rectangle.

[0031] Specifically, refer to Figure 3 As shown, the partition template 2 includes a shell 21, a baffle plate 22 and a movable component. The shell 21 includes side panels 211 and end panels 212 connected to both ends of the side panels 211. An opening is provided in the middle of the end panel 212, and the opening surrounds the column pier to form a casting channel. Accordingly, the outer contours of the opening and the casting channel are also rectangular. The baffle plates 22 are respectively attached to the end panels 212 arranged above and below the side panels 211. The baffle plate 22 includes a plurality of sub-plate bodies 221 movably connected at the head and tail to form an open and close structure. The movable components are respectively connected to each sub-plate body 221, and are used to drive each sub-plate body 221 to move so that the blocking plate 22 forms an open state and a closed state; the blocking plate 22 exposes the casting channel in the open state, and during casting, the ultra-high performance concrete can flow through the casting channel into the casting space of the next layer; the blocking plate 22 blocks the casting channel in the closed state, which can prevent the cast ultra-high performance concrete from continuing to flow downward. At this time, the side plates 211, the upper and lower end plates 212, and the upper and lower blocking plates 22 form a closed state, thereby forming a gap between the strip structural layers 9 after casting.

[0032] The present embodiment provides an integrated pouring and maintenance device for outsourcing reinforcement of piers, which can drive the barrier plate 22 to open and close through a movable component, and can switch the pouring channel on and off. When pouring a strip structural layer 9 of a certain layer, the pouring channel above it can be opened and the pouring channel below it can be closed, so that pouring can be carried out directly from the top. Only one set of pouring system needs to be arranged to pour each strip structural layer 9 separately; an outer mold 11 is arranged outside the inner mold 12 to form an integrated pouring and maintenance structure, which makes the maintenance operation more convenient.

[0033] It should be noted that, referring to Figure 1 As shown, a top plate 3 is positioned above the topmost casting formwork 1. When arranging the casting system, a casting port can be provided on the top plate 3 or in the gap between the top plate 3 and the column pier. A shielding plate 5 is also positioned above the top plate 3. This shielding plate 5 comprises two plates butt-jointed and assembled on the column pier. This shielding plate 5 provides protection from debris when casting is not underway. It can be removed during casting.

[0034] Specifically, refer to Figure 3-Figure 5 As shown, a guide structure is provided between the end plate 212 and the baffle plate 22 below the side plate 211. The guide structure extends in a direction away from the partition template 2, with this extension direction being perpendicular to the surface of the pier. The sub-plate body 221 below the side plate 211 is movably connected to the end plate 212 via the guide structure, allowing the sub-plate body 221 to move along the extension direction of the guide structure. The movable assembly includes a connecting column 23 and a limiting plate 24; the ends of the connecting column 23 are respectively connected to the sub-plate bodies 221 of the upper and lower baffle plates 22. The limiting plate 24 is provided with a guide slot 241 for each connecting column 23 to pass through, so that when the limiting plate 24 rotates, it drives the connecting column 23 to move along the extension direction of the guide structure.

[0035] In the embodiment, the guide groove 241 includes a first end and a second end, and the distance between the guide groove 241 and the center of the column decreases from the first end to the second end. Under the restriction of the guide structure and the guide groove 241, when the limit plate 24 rotates, it can drive the connecting column 23 to move along the extension direction of the guide structure, thereby driving the connecting column 23 to move closer to or away from the column, realizing the opening or closing of the blocking plate 22. The opening state of the blocking plate 22 is shown in FIG. Figure 4 As shown, the closed state of the blocking plate 22 is shown in FIG. Figure 5 shown.

[0036] Specifically, refer to Figure 7 and Figure 8 As shown, the sub-plate 221 has a first insertion slot 222 at one end and a first insertion portion 223 at the other end. The first insertion portion 223 is movably inserted into the first insertion slot 222. Specifically, the barrier plate 22 includes four sub-plates 221. Adjacent sub-plates 221 are perpendicular to each other, so that the first insertion slot 222 includes two mutually perpendicular and connected notches. The first insertion portion 223 is inserted into the first insertion slot 222 through the two notches. The four sub-plates 221 are movably connected end to end, forming a rectangular channel. When the barrier plate 22 is in the open state, the portion of the rectangular channel that does not overlap with the column pier allows the passage of ultra-high performance concrete.

[0037] Specifically, continue to refer to Figure 3 and Figure 8As shown, the guiding structure includes a first slideway 213 provided on the end plate 212 and a first slider 224 provided on the sub-plate body 221. The first slider 224 is slidably arranged in the first slideway 213 along the extending direction of the first slideway 213.

[0038] Specifically, it further includes a first driving assembly 6. Continuing to refer to Figure 1 As shown, the first driving assembly 6 includes a first driving element 61 and a first control rod 62. The first driving element 61 is installed on the top casting form 1, that is, installed on the top plate 3. Refer to Figure 3 As shown, an extending rod 242 is connected to the limiting plate 24, and a through groove for the extending rod 242 to extend outwards is provided on the housing 21. The extending rod 242 passes through the through groove and extends out of the housing 21. The first driving element 61 is connected to the first control rod 62; the first control rod 62 includes a plurality of sub-control rods 621 detachably connected end to end, and each sub-control rod 621 is respectively connected to the extending rod 242 of a partition template 2; so that the first driving element 61 drives the first control rod 62 to swing and drives the limiting plate 24 to rotate. Specifically, the sub-control rods 621 can be connected by threads, or can be sleeved with sleeves, or can be connected by pins, etc.

[0039] During the pouring process, pouring is always carried out in a bottom-up manner. Before pouring a certain layer of the strip-shaped structure layer 9, first use the first driving assembly 6 to drive the baffle plates 22 of the nearest layer of partition templates 2 below it and the baffle plates 22 of all the partition templates 2 above it to close. Then remove the sub-control rod 621 connected to the limiting plate 24 of the nearest layer of partition template 2 below the strip-shaped structure layer 9, and then use the first driving assembly 6 to drive all the baffle plates 22 above the strip-shaped structure layer 9 to open, while the baffle plates 22 below the strip-shaped structure layer 9 will be in a closed state; thus, the baffle plates 22 above the strip-shaped structure layer 9 can be switched to an open state, and the baffle plates 22 below can be switched to a closed state, so as to pour the strip-shaped structure layer 9 of this layer.

[0040] Specifically, the housing 21 includes an upper housing 214 and a lower housing 215; the upper housing 214 is movably inserted into the lower housing 215; a plurality of connection holes 216 arranged in the vertical direction are provided on the side wall of the lower housing 215; the upper housing 214 and the lower housing 215 are connected by a first bolt 217, and the first bolt 217 passes through connection holes 216 at different heights to adjust the thickness of the partition template 2. By passing the first bolt 217 through connection holes 216 at different heights to lock the upper housing 214 and the lower housing 215, the thickness adjustment of the partition template 2 can be realized, and thus the thickness adjustment of the gap can be realized. When installing the integrated pouring and curing device, the thickness of the partition template 2 can be adjusted according to the gap thickness first.

[0041] Specifically, referring to Figure 3 、 Figure 7 and Figure 14 As shown, the connecting column 23 includes a first column body 231 and a second column body 232; a jack 225 for receiving the insertion of the first column body 231 is provided on the sub-plate body 221 in contact with the upper housing 214, and the second column body 232 is connected to the sub-plate body 221 in contact with the lower housing 215; the first column body 231 is threadedly connected to the second column body 232. During installation, the length of the connecting column 23 is adjusted according to the thickness of the partition template 2. When installing the upper housing 214, the second column body 232 is inserted into the jack 225, and the connecting column 23 can form a support between the upper housing 214 and the lower housing 215, thereby improving the bearing capacity of the partition template 2.

[0042] Specifically, referring to Fig. 9 As shown, the inner mold 12 includes a plurality of sub-templates 121 that are movably connected end to end. A second insertion groove 122 is provided on one side of the sub-template 121, and a second insertion portion 123 is provided on the other side. The second insertion portion 123 is inserted into the second insertion groove 122. In this embodiment, a total of four sub-templates 121 are provided, and each sub-template 121 is a right-angle structure. The four sub-templates 121 are movably connected, so that the size of the space surrounded by the middle part is adjustable, and thus the pouring thickness of the strip-shaped structure layer 9 can be adjusted.

[0043] A connecting rod 124 is connected to the sub-template 121; the connecting rods 124 between the inner molds 12 at different floor heights are connected to each other, and a limiting groove 219 is provided on the end plate 212; a corrugated partition cover 201 is provided in the limiting groove 219, and a through hole for receiving the connecting rod 124 to pass through is provided on the corrugated partition cover 201. By providing the corrugated partition cover 201 in the limiting groove, it is possible to prevent the ultra-high performance concrete from falling into the interior of the partition template 2 from the limiting groove.

[0044] Referring to Figure 12As shown in the figure, it further includes a second driving component 7. The second driving component 7 includes a second driving element 71, a gear 72, a ring 73 and an arc-shaped connecting rod 74. The second driving element 71 is installed on the top casting formwork 1. The gear 72 is connected to the second driving element 71, and the second driving element 71 drives the gear 72 to rotate. The ring 73 surrounds the outside of the pier, and its side surface is provided with teeth meshing with the gear 72. One end of the arc-shaped connecting rod 74 is hinged to the ring 73, and the other end is hinged to the connecting rod 124. When the second driving element 71 drives the ring 73 to rotate, it drives the connecting rod 124 to move along the limiting channel 219, so as to drive the sub-formwork 121 to open and close. When the second driving element 71 drives the ring 73 to rotate, under the restriction of the arc-shaped connecting rod 74 and the limiting channel 219, the connecting rod 124 moves along the extending direction of the limiting channel 219, so as to adjust the thickness of the four sub-formworks 121 and the strip-shaped structure layer 9. It should be noted that a guide rail structure is also provided between the connecting rod 124 at the top and the baffle 5, and the extending direction of the guide rail structure is the same as that of the limiting channel 219.

[0045] It should be noted that after the integrated casting and curing device is assembled, by driving the sub-formwork 121 to move through the second driving component 7, the thickness of the strip-shaped structure layer 9 can be uniformly adjusted according to requirements. When curing is required after casting is completed, the sub-formwork 121 can be driven by the second driving component 7 to continue to move outwards, so that the second insertion slot 122 is separated from the second insertion part 123. At this time, the cast concrete is directly exposed to the preparation space, and steam can be introduced for curing.

[0046] It should be noted that with reference to Fig. 9 As shown in the figure, a second slideway 41 is provided on the surface of the bottom plate 4, and a roller 125 is provided on the lowermost connecting rod 124, so that the roller 125 is slidably arranged in the second slideway 41. The extending direction of the second slideway 41 is the same as that of the limiting channel 219, and its extending direction is on the diagonal line of the rectangular pier.

[0047] It should be noted that in this embodiment, structures such as the top plate 3, the bottom plate 4, the outer shell, and the outer formwork 11 are all structures symmetrically spliced along a diagonal line of the rectangular pier, and can be specifically spliced by bolts, so as to facilitate the installation of the entire device on the pier. In this embodiment, the bottom plate 4, the outer formwork 11, and the outer shell arranged in sequence in the vertical direction can be inserted and assembled by a fixed shaft 42.

[0048] Specifically, it further includes a steam curing system 8. The steam curing system 8 includes a steam box 81 and a steam pipeline 82. The steam pipeline 82 connects the outer formwork 11 and the steam box 81, so that the steam box 81 conveys steam into the preparation space. A corresponding steam pipeline 82 is respectively connected to each casting formwork 1 to inject steam into each preparation space for curing.

[0049] Example 2 This embodiment provides a method for strengthening a column pier using the integrated casting and curing device described in Example 1. Referring to Figure 15 as shown, the method includes the following steps: S1. Precast the mold; S2. Clean the site and the column pier to be strengthened; S3. Moisten the surface of the column pier and apply a release agent; S4. Assemble the integrated casting and curing device; S5. Pour the casting forms 1 layer by layer from bottom to top to form a plurality of strip-shaped reinforcement belts arranged at intervals; S6. When pouring one of the casting forms 1, close the baffle 22 below the casting form 1 and open the baffle 22 above it, and perform grouting from the top; S7. Curing treatment; S8. Demold.

[0050] When precasting the mold in step S1, design the mold size according to requirements, the actual situation on site and the requirements for strengthening, and precast the mold size. During subsequent use, the size of the gap and the pouring thickness can be adjusted, which has a certain degree of versatility.

[0051] In step S2, in order to facilitate the construction, the site needs to be leveled. In order to ensure the bonding effect between the ultra-high performance concrete and the square bridge pier and ensure the effectiveness of the strengthening, the surface of the old bridge pier to be strengthened is roughened and cleaned to remove the dust, oil stains, spalled and loose layers on the surface, or some possible harmful substances.

[0052] In step S3, the concrete surface needs to be moderately moistened, but excessive moisture should be avoided because this may lead to a decrease in the interfacial bonding force. The moistening treatment helps to improve the bonding force between the old concrete and the ultra-high performance concrete; transport the precast mold to the construction site. In order to ensure that the movable formwork can move smoothly during curing and final demolding and ensure that it is not stuck and the curing process cannot proceed smoothly, a release agent needs to be applied to the inner formwork.

[0053] In step S4, during the assembly process, assemble in a bottom-up manner, and after the assembly is completed, adjust the position of the sub-form 121 according to the thickness of the strip-shaped structure layer 9 through the second driving component 7.

[0054] In step S6, when specifically pouring a strip structure layer 9 of a certain layer, first use the first driving component 6 to drive the baffle plates 22 of the lowermost layer of partition templates 2 below it and the baffle plates 22 of all the partition templates 2 above it to close. Then, remove the sub-control rod 621 connected to the limiting plate 24 of the lowermost layer of partition templates 2 below the strip structure layer 9, and then use the first driving component 6 to drive all the baffle plates 22 above the strip structure layer 9 to open, while the baffle plates 22 below the strip structure layer 9 will be in a closed state; thus, the baffle plates 22 above the strip structure layer 9 can be switched to an open state, and the baffle plates 22 below can be switched to a closed state, so as to pour the strip structure layer 9 of this layer.

[0055] In step S7, after the ultra-high performance concrete solidifies, the second driving component 7 drives the sub-template 121 to move to demold it, and separates the second insertion portion 123 from the second insertion groove 122. At this time, the poured concrete is exposed to the reserved space, and then external steam can be introduced for curing.

[0056] It should be noted that, as shown in Fig. 9 below, a bottom plate 4 is provided as a bottom mold below the lowermost pouring mold 1, and the end plates 212 and baffle plates 22 in other pouring molds 1 are used as bottom molds.

[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope recorded in this specification.

[0058] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
