Description

Technical Field

[0001] This invention belongs to the field of concrete construction technology, and particularly relates to a construction device and method for a ring-shaped corbel reinforced concrete beam-column joint. Background Technology

[0002] With the continuous development of engineering construction, steel-concrete composite columns, as a combined structure that can fully utilize the properties of steel and concrete materials, have been widely used in engineering. As an important beam-column joint in steel-concrete composite columns, the previously relatively simple connection between steel beams and steel-concrete composite columns or between reinforced concrete beams and steel-concrete composite columns has evolved into a connection form with both reinforced concrete beams and ring beams as well as steel beams through-core connections, which is more complex in terms of stress and structure, thus improving the technical rationality and economic advantages.

[0003] The complex ring beam-ring corbel steel-reinforced concrete beam-column joint is a complex structural form that combines reinforced concrete beams and ring beams with through-core steel beams. In this complex joint, the fabrication of the ring beam's main reinforcing bars is difficult and time-consuming. During the reinforcement detailing and fabrication process, scaffolding is typically built to support the concrete beam and column to increase the space for reinforcement binding. However, current concrete beam and column scaffolding is generally fixed, requiring disassembly of multiple joints for transportation, which is cumbersome and inconvenient during assembly. Furthermore, when binding reinforcement on the scaffolding surface, after binding one section, the beam and column often need to be lifted and the angle adjusted before binding the next section, which is quite troublesome. Therefore, researching a new construction device and method for the ring corbel steel-reinforced concrete beam-column joint to solve these problems is of great significance. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a construction device and method for a ring-shaped corbel reinforced concrete beam-column joint.

[0005] This annular corbel rigid concrete beam-column joint construction device includes a beam-column construction mechanism and a construction drive mechanism.

[0006] The beam and column construction mechanism includes multiple construction frames arranged in parallel, which are connected by telescopic components, and steel beams and columns are erected on top of the multiple construction frames;

[0007] The construction drive mechanism includes a drive assembly fixedly connected to one of the construction frames. The drive assembly is meshed with a transmission assembly, which is fixedly installed between two adjacent construction frames. Two gear ring assemblies are meshed above the transmission assembly, and the two gear ring assemblies are supported on the two adjacent construction frames respectively. The top of the gear ring assembly has an opening, and locking components are provided on both sides inside the gear ring assembly. The steel beam passes through the two gear ring assemblies, and the four locking components cooperate to fix the steel beam. When the transmission assembly rotates, the gear ring assembly and the steel beam rotate synchronously.

[0008] Preferably, one of the construction frames is fixedly connected to a support base at its bottom, and the bottoms of the other construction frames are fixedly connected to casters. Lifting rings are fixedly connected to the top of both sides of the construction frame. The top of the construction frame is V-shaped, and rollers are connected to both sides of each V-shape. The steel beams are mounted on multiple rollers, and the rotation axis of the rollers is parallel to the length direction of the steel beams.

[0009] Preferably, the telescopic assembly includes a first telescopic assembly and a second telescopic assembly. The first telescopic assembly includes a first telescopic frame, and a connecting plate is provided at the bottom of the construction frame. The first telescopic frame is hinged to each connecting plate. A sliding groove is provided below the connecting plate. The sliding groove is perpendicular to the telescopic direction of the telescopic assembly. A slider is slidably connected inside the sliding groove. Multiple sliders are hinged to the first telescopic frame. Two sliders of the construction frame at both ends are fixed by bolts and connecting plates to achieve temporary locking.

[0010] Preferably, the second telescopic component includes a second telescopic frame, which is hinged to multiple construction frames. Sliding sleeves are slidably connected to the construction frames, and the second telescopic frame is also hinged to multiple sliding sleeves. The sliding sleeves on the construction frames at both ends are fixed to the construction frames by bolts to achieve temporary locking.

[0011] Preferably, the drive assembly includes a motor, the output shaft of which is fixedly connected to a first gear, and the bottom of the motor is fixedly connected to a mounting bracket, which is fixedly connected to one of the construction frames.

[0012] Preferably, the transmission assembly includes a connecting column, a sleeve slidably connected to the connecting column, a rotating shaft fixedly connected to the connecting column, and second gears fixedly connected to both the rotating shaft and the sleeve. One of the second gears meshes with a first gear, and the two second gears mesh with two gear ring assemblies respectively.

[0013] The transmission assembly is equipped with bearings at both ends, and the rotating shaft and sleeve are rotatably connected in the two bearings, with the two bearings fixedly installed on the two construction frames.

[0014] The connecting post has a polygonal shape, and the inner ring of the sleeve is adapted to the shape of the connecting post.

[0015] Preferably, the gear ring assembly includes a gear ring, and the gear rings of the two gear ring assemblies are respectively meshed with two second gears. There is a notch on the gear ring, and two arc-shaped tooth segments are respectively hinged at the notch of the gear ring by two hinges. The two arc-shaped tooth segments are joined together to close the gear ring. A connector is fixedly connected to one of the arc-shaped tooth segments, and the connector is fixed to the other arc-shaped tooth segment by bolts.

[0016] The gear ring assembly is supported circumferentially by four guide wheels on its outer side, and the four guide wheels are fixedly connected to the construction frame. The gear ring assembly rotates between the four guide wheels.

[0017] Preferably, the portion of the inner ring of the toothed ring opposite the arc-shaped tooth segment is a straight structure, and the side of the arc-shaped tooth segment facing the center of the toothed ring is also a straight structure. The locking assembly includes an electric push rod, which is fixedly connected to the inner ring of the toothed ring. One end of the electric push rod is fixedly connected to an arc-shaped clamping plate, which fits against the steel beam column. Both the upper and lower ends of the arc-shaped clamping plate are fixedly connected to support frames, and the support frames are equipped with pulleys. When the electric push rod extends or retracts, the two upper pulleys slide on the two straight structures of the arc-shaped tooth segments facing the center of the toothed ring, and the two lower pulleys slide on the straight structure of the toothed ring.

[0018] The construction method of this annular corbel rigid concrete beam-column joint construction device includes the following steps:

[0019] S1. Multiple construction frames are deployed through telescopic components to ensure that the length of the construction frames meets the requirements for the erection of steel beams and columns. The opening and closing of the toothed ring component is opened to hoist the steel beams and columns into the toothed ring component and place them on the construction frame. After closing the opening and closing of the toothed ring component, the steel beams and columns are clamped and positioned by the locking component.

[0020] S2. Position the ring beam and ring reinforcement on the steel beam and column. After the ring beam and ring reinforcement are positioned and arranged on one side of the steel beam and column, the drive component drives the transmission component to rotate the two gear ring components. The rotation of the gear ring components will drive the steel beam and column to rotate through the locking component. At this time, the construction of the positioning ring beam and ring reinforcement will continue until the ring beam and ring reinforcement are tied and formed.

[0021] S3. Then, operate the locking assembly to retract and open the gear ring assembly opening to lift and remove the steel beam column with ring beam, complete the formwork operation, and carry out concrete pouring and curing operations.

[0022] As a preferred option, depending on the location of the steel beam and column where ring beams and reinforcing bars need to be constructed, some of the construction scaffolds at the corresponding locations are discarded, thereby increasing the spacing between the two construction scaffolds on both sides of the location where the ring beams and reinforcing bars need to be constructed, thus providing space for construction.

[0023] The beneficial effects of this invention are:

[0024] 1) This invention uses a motor to drive a first gear and a second gear for transmission. The second gear drives the rotating rod and the connecting column to rotate. The connecting column drives another second gear to rotate through a sleeve. The two second gears are then connected to two gear ring assemblies. The two gear ring assemblies can drive the steel beam to rotate through a locking assembly. This allows the steel beam to rotate smoothly using rollers, preventing the rotation of the steel beam from being obstructed. The rotation of the steel beam allows workers to easily lay steel bars on multiple sides of the steel beam, avoiding the need for subsequent hoisting and angle adjustment of the steel beam for continued construction, which would have been cumbersome and thus improved construction efficiency.

[0025] 2) The telescopic assembly proposed in this invention connects the slider and sliding sleeve to the construction frame. The temporary lock can be released by removing the bolts, at which point the construction frame can be unfolded. The construction frame can be unfolded by relying on the first telescopic frame and the second telescopic frame, thereby extending the support length of the steel beams and columns. It can also be adjusted for steel beams and columns of different lengths, improving applicability. Moreover, the construction frame adopts a combined integrated design, avoiding the problems of traditional disassembly and on-site construction, greatly improving construction efficiency and reducing manpower. Secondly, the construction frame eliminates individual construction frames at the construction location, thereby increasing the distance between two construction frames, thus expanding the construction area and facilitating construction work for workers. Furthermore, the construction frame has an open top and a consistent height, thus avoiding the inconvenience and safety issues caused by the high extension height required by traditional scaffolding methods, which necessitate workers to work above the steel beams and columns.

[0026] 3) The construction method proposed in this invention overcomes the complexity of constructing complex multi-elevation ring beams and ring corbel reinforced concrete beam-column joints, solves the difficulties in tying ring beam reinforcement and installing formwork caused by too many through-core steel members, avoids construction in confined spaces, can be connected to different types of floor beams in any direction, and divides complex processes and procedures into segments for independent fabrication, and then organically combines them to form a set of segmented construction, overall assembly, and parallel flow construction processes, which improves construction efficiency and quality, reduces labor costs, and has significant economic benefits.

Detailed Implementation

[0037] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that those skilled in the art can make several modifications to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0038] Example 1

[0039] As one example, such as Figures 1 to 9 As shown, the construction device for the ring-shaped corbel reinforced concrete beam-column joint includes:

[0040] The beam-column construction mechanism 100 includes multiple construction frames 101 arranged side by side. Each construction frame 101 has a V-shape on its top, and rollers 105 are fixedly connected to both sides of each V-shape. The V-shape structure allows the two rollers 105 to support the two sides of the steel beam-column 108, maintaining the stability of the steel beam-column 108. The steel beam-column 108 is supported on the multiple rollers 105, which also assist the steel beam-column 108 in smooth rotation. The multiple construction frames 101 are assembled and connected by a first telescopic component 102 below. The multiple construction frames 101 are also connected by two second telescopic components 103 on both sides. The steel beam-column 108 is supported on top of the multiple construction frames 101.

[0041] The construction drive mechanism 200 includes a drive assembly 201, which includes a motor 2011. A first gear 2012 is fixedly connected to the output shaft of the motor 2011. A fixing frame 2013 is fixedly connected to the bottom of the motor 2011, securing the motor 2011 and ensuring its stability. The fixing frame 2013 is fixedly connected to one of the construction frames 101. The drive assembly 201 is fixedly connected to one of the construction frames 101. A transmission assembly 205 is meshed above the drive assembly 201. The transmission assembly 205 includes a connecting column 2051, a sleeve 2052 slidably connected to the connecting column 2051, and a rotating shaft 2054 fixedly connected within the connecting column 2051. A second gear 2053 is fixedly connected to both shaft 2054 and sleeve 2052. One of the second gears 2053 meshes with the first gear 2012. Through the transmission between the first gear 2012 and the second gear 2053, the rotating shaft 2054 can be driven to rotate. The rotating shaft 2054 and sleeve 2052 are respectively rotatably connected in two bearings 2055. The rotating shaft 2054 and sleeve 2052 can maintain smooth rotational movement through the bearings 2055. The two bearings 2055 are fixedly installed on two construction frames 101. The connecting column 2051 has a polygonal structure. The inner ring shape of the sleeve 2052 is adapted to the shape of the connecting column 2051. The sleeve 2052 can slide on the connecting column 2051, thereby allowing the construction frame 101 to move. The structure allows for smooth deployment. Furthermore, the polygonal structure of the connecting column 2051 and sleeve 2052 ensures that rotating the connecting column 2051 drives rotating the sleeve 2052, thus preventing the second gear 2053 from failing to drive due to rotation within the connecting column 2051 and sleeve 2052. The transmission assembly 205 is fixedly installed between the two construction frames 101. The upper part of the transmission assembly 205 meshes with two gear ring assemblies 202. Locking assemblies 203 are fixedly connected to both sides of the inside of the gear ring assembly 202. Each locking assembly 203 includes an electric push rod 2032, which is fixedly connected to the inner ring of the gear ring 2021. One end of the electric push rod 2032 is fixedly connected to an arc-shaped clamping plate 2031, which fits against the steel beam column 10. 8. The extension movement of the electric push rod 2032 causes it to push the arc-shaped clamping plate 2031 to move, bringing the two arc-shaped clamping plates 2031 closer together to press against the steel beam column 108, thereby locking the position of the steel beam column 108 and maintaining its stability. Furthermore, the gear ring assembly 202 can drive the steel beam column 108 to rotate smoothly through the locking assembly 203. Support frames 2033 are fixedly connected to both the upper and lower ends of the arc-shaped clamping plate 2031, and pulleys 2034 are fixedly connected to the support frames 2033. The pulleys 2034 support the gear ring 2021 and the arc-shaped gear segment 2022, improving the strength of the gear ring assembly 202. The two upper pulleys 2034 slide on the two arc-shaped gear segments 2022 respectively.Two lower pulleys 2034 slide on the gear ring 2021. Four locking components 203 cooperate to fix the steel beam 108. The steel beam 108 passes through the two gear ring assemblies 202. The gear ring assembly 202 includes a gear ring 2021. The two gear rings 2021 are meshed with two second gears 2053. Two arc-shaped tooth segments 2022 are hinged to the top of the gear ring 2021 by two hinges 2024. The arc-shaped tooth segments 2022 are flipped by the hinges 2024, thereby opening the opening of the gear ring 2021, which facilitates placing the steel beam 108 on the construction frame 101. At the same time, by flipping the two arc-shaped tooth segments 2022, the opening of the gear ring 2021 can be opened, thus facilitating the placement of the steel beam 108 on the construction frame 101. The gear ring 2021 is closed and then fixed with bolts to form a circular structure with the two arc-shaped tooth segments 2022 and the tooth ring 2021, allowing for smooth transmission with the second gear 2053. The two arc-shaped tooth segments 2022 are connected, with a connector 2023 fixedly connected to one of them, and the connector 2023 is bolted to the other arc-shaped tooth segment 2022. The tooth ring 2021 is supported by four guide wheels 204, which support and limit its movement while allowing it to rotate smoothly. The four guide wheels 204 are fixedly connected to the construction frame 101.

[0042] In this embodiment, the motor 2011 drives the first gear 2012 and the second gear 2053 to transmit power, causing the second gear 2053 to drive the rotating rod and the connecting column 2051 to rotate. The connecting column 2051 drives another second gear 2053 to rotate through the sleeve 2052, so that the two second gears 2053 transmit power to the two gear ring assemblies 202. The two gear ring assemblies 202 can drive the steel beam column 108 to rotate through the locking assembly 203, so that the steel beam column 108 can be smoothly rotated by the roller 105, avoiding the obstruction of the rotation of the steel beam column 108. The rotation of the steel beam column 108 makes it convenient for workers to lay steel bars on multiple sides of the steel beam column 108, avoiding the need for subsequent hoisting of the steel beam column 108 to adjust the angle and continue construction, which would have caused cumbersome problems, thereby improving construction efficiency.

[0043] Example 2

[0044] As another embodiment, this second embodiment is proposed based on the first embodiment, combined with the appendix. Figure 2 and attached Figure 5The first telescopic assembly 102 includes a first telescopic frame 1021, which is hinged to multiple connecting plates 1022. The connecting plates 1022 are fixedly connected to the bottom of the construction frame 101. A sliding groove 1023 is provided below the connecting plate 1022. A slider 1024 is slidably connected inside the sliding groove 1023. The slider 1024 can slide in the sliding groove 1023, so that the first telescopic frame 1021 can be extended and retracted smoothly. The slider 1024 can be fixed to the first telescopic frame 1021 by bolts, ensuring the stability of the construction frame 101. Multiple sliders 1024 are hinged to the first telescopic frame 1021, and the two outermost sliders 1024 are fixed to the connecting plate 1022 by bolts.

[0045] The second telescopic assembly 103 includes a second telescopic frame 1031, which is hinged to multiple construction frames 101. The second telescopic frame 1031 is also hinged to multiple sliding sleeves 1032, which are slidably connected to the corresponding construction frames 101. The two outermost sliding sleeves 1032 are fixed to the construction frames 101 by bolts. The sliding sleeves 1032 can slide on the construction frames 101, allowing the second telescopic frame 1031 to move smoothly in telescopic motion. The sliding sleeves 1032 and the second telescopic frame 1031 can be fixed by bolts to improve the stability of the construction frames 101. Moreover, the two second telescopic frames 1031 and the first telescopic frame 1021 can reinforce the construction frames 101.

[0046] The construction frame 101 has a V-shape on top, and each V-shape has rollers 105 fixedly connected to both sides. The steel beams 108 are supported on multiple rollers 105. The bottom of one of the construction frames 101 is fixedly connected to a support base 106, and the bottom of the other construction frames 101 is fixedly connected to a movable wheel 107. The movable wheel 107 can be used to easily unfold the construction frame 101, making the operation more labor-saving. The top of the construction frame 101 is fixedly connected to two lifting rings 104, which can be used to hoist and arrange the construction frame 101 as needed.

[0047] In this embodiment: by removing the bolts on the slider 1024 and the sliding sleeve 1032, the construction frame 101 can be unfolded. The construction frame 101 can be unfolded with the help of the first telescopic frame 1021 and the second telescopic frame 1031, thereby extending the support length of the steel beam column 108. It can also be adjusted according to the steel beam column 108 of different lengths, improving applicability. Moreover, the construction frame 101 adopts a combined integrated design, avoiding the problems of traditional disassembly and assembly of the construction frame 101 and the on-site construction frame 101, which greatly improves construction efficiency and reduces manpower. Secondly, the construction frame 101 can discard a single construction frame 101 at the construction location, thereby increasing the distance between two construction frames 101, thus expanding the construction area and facilitating the construction work of the workers. In addition, the construction frame 101 is open at the top and the height is consistent, thus avoiding the inconvenience and safety problems caused by the traditional scaffolding method, which requires workers to work above the steel beam column 108 due to the high extension height.

[0048] It should be noted that the parts in this embodiment that are the same as or similar to those in Embodiment 1 can be referred to each other, and will not be repeated in this application.

[0049] Example 3

[0050] As another embodiment, this third embodiment, based on embodiments one and two, proposes a construction method for this annular corbel stiffened concrete beam-column joint construction device, including the following steps:

[0051] S1. During construction, first remove the bolts of the fixed slider 1024 and the sliding sleeve 1032, and unfold the construction frame 101 so that multiple construction frames 101 can be unfolded through the first telescopic frame 1021 and the second telescopic frame 1031, so that the length of the construction frame 101 meets the requirements for the erection of the steel beam column 108. Then, remove the bolts of the connector 2023 and flip the arc-shaped toothed segment 2022 outward. Then, hoist the steel beam column 108 from above the toothed ring 2021 through the roller 105 placed on the construction frame 101. Then, merge the two arc-shaped toothed segments 2022 and lock them with bolts. At this time, operate the electric push rod 2032 to extend, so that the electric push rod 2032 pushes the arc-shaped clamping plate 2031 to move. The two arc-shaped clamping plates 2031 press against each other against the steel beam column 108, so that the steel beam column 108 is positioned.

[0052] S2. Based on the location of the steel beam column 108 where the ring beam and ring reinforcement need to be constructed, discard a portion of the construction frame 101 at the corresponding position. Since the arrangement of a single construction frame 101 is discarded between two construction frames 101, the distance between the two construction frames 101 is increased. At this time, the ring beam and ring reinforcement are positioned on the steel beam column 108 at this gap. After the ring beam and ring reinforcement are positioned on one side of the steel beam column 108, the motor 2011 is controlled to drive the first gear 2012 and the second gear 2053 to drive the shaft 2054 and the connecting column 2051 to rotate. The connecting column 2051 drives the other second gear 2053 to rotate through the sleeve 2052. The second gear 2053 drives the gear ring assembly 202 to drive the steel beam column 108 to rotate through the locking assembly 203. At this time, the construction continues until the ring beam and ring reinforcement are tied and formed.

[0053] S3. Then, operate the locking component 203 to retract and open the upper arc-shaped toothed segment 2022. The steel beam column 108 with the ring beam is hoisted into the formwork again. The nodes of the steel beam column 108 are adjusted to connect with the lower steel beam column 108. Then, the two steel beam columns 108 are welded together. The ring sealing template support system is used to clamp the steel pipe beam and reinforce it against the bottom formwork of the ring beam. Finally, the concrete is poured and cured.

[0054] The specific binding procedures for the ring beam reinforcement are as follows: Based on the actual height difference between the bottom formwork of the ring beam and the top elevation of the steel pipe beam column, determine the positions of the bottom and top surfaces of the ring beam on the node of the corbel steel pipe beam to be hoisted on this floor. According to the design drawings, mark the precise positions of the ring reinforcement of each layer on the corbel steel pipe beam node. Slowly lift one end of the corbel steel pipe beam node and insert the upper ring reinforcement in sequence. Use the same method to lift one end of the steel pipe beam and insert the lower ring reinforcement. Then, according to the design positions of the upper and lower ring reinforcements and the requirements of the protective layer, determine the planar positions of the upper and lower ring reinforcement positioning and fixing support bars on the corbel steel pipe beam node. Complete the welding of the positioning and fixing support bars. Before welding the support bars, the ring reinforcements should be arranged on both sides of the corresponding fixing support bars according to the distribution of the single or multi-layer design and construction drawings of the upper and lower ring reinforcements.

[0055] When binding the waist reinforcement of the ring beam, first mark the plane position of the waist reinforcement on the steel pipe beam according to the distribution of the waist reinforcement along the height of the ring beam. Then, according to whether there are steel beam corbels on the plane where the waist reinforcement of the ring beam is located and the number of corbels, the ring reinforcement can be cut into sections for welding and binding. The number of sections is equal to the number of steel beam corbels in the plane where the waist reinforcement is located. The length of the section should be the arc length formed by the angle between the corresponding ring reinforcement and the corbel web. When welding the section reinforcement, in order to ensure that the welding length and stress of the waist reinforcement and the steel beam corbel web meet the specifications, stiffening rib support plates are welded on the plane where the waist reinforcement of the ring beam is located on both sides of the steel beam corbel web. Then, the section arc reinforcement is welded to the contact surface of the support plate to form a whole ring beam waist reinforcement. Bind the ring beam stirrups. The diameter and spacing of the stirrups are configured and bound according to the design requirements. The binding of the ring beam reinforcement is completed on the construction frame 101.

[0056] The procedures for hoisting steel beam-column 108 into the formwork are as follows: After completing the binding and welding of the ring beam reinforcement on the construction frame 101, the steel pipe beam node with ring beam is hoisted into the formwork using the hoisting technology. Pre-embedded pull rings are placed at the bottom of the construction frame 101 to increase its stability. Then, three steel plate lifting lugs are welded symmetrically to the upper end of the steel pipe beam and both ends of the steel frame beam corbel. The steel strand is first passed through the lifting lugs of the upper end of the steel pipe beam and the steel frame beam corbel on the same side. When the lifting angle is 45°, it is then passed through the lifting lugs of the steel frame beam corbel on the other side. The steel pipe beam with corbel is lifted vertically and finally hoisted into the formwork. After the steel beam-column 108 is in place, the verticality of the steel beam-column 108 is observed and adjusted with a level instrument to achieve seamless connection with the lower layer steel beam-column 108. Finally, it is welded into shape according to the design and detailed drawings to ensure the welding quality. Ultrasonic testing was performed on the welding surfaces of the 19 butt joint steel beam-column 108 on the upper and lower layers, and all of them met the requirements of the first-class weld.

[0057] The specific steps for reinforcing and forming the ring beam formwork support system are as follows: Use the ring-shaped sealing template to clamp the steel beam column 108 and tightly attach it to the bottom formwork of the ring beam, sealing the 50mm gap between the steel beam column 108 and the inner circle of the bottom formwork of the ring beam to prevent gaps from appearing between the ring beam formwork and the steel beam column 108 when pouring concrete. Then, complete the reinforcement of the ring beam bottom formwork support system and connect it to the surrounding frame structure support frame 2033 along its entire length. Finally, use the cylindrical formwork support ring fastening device to complete the reinforcement of the side formwork.

[0058] Specific matters concerning the concrete pouring and curing of the ring beam are as follows: Due to the large height-to-width ratio and dense reinforcement of the ring beam, in order to ensure the concrete is vibrated and compacted, 5-10mm aggregate is used to ensure smooth concrete pouring into the formwork. At the same time, the water-cement ratio of the concrete on site must also be controlled, with a slump of ≥160mm and ≤200mm being appropriate. After the concrete is poured, proper curing is necessary to prevent carbonation and shrinkage cracking due to sun exposure. Water curing should exceed 14 days.

[0059] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
