Description

Technical Field

[0001] This utility model belongs to the field of construction technology of cast-in-place wave barrier walls, and in particular relates to a formwork trolley structure for cast-in-place concrete structures with irregular cross-sections. Background Technology

[0002] As an important coastal or hydraulic structure, wave-breaking walls are typically constructed using cast-in-place columns to ensure their integrity and stability. Traditional methods often employ on-site assembly of wooden formwork for the construction of cast-in-place concrete columns. This method has several drawbacks, including the need for continuous support from lifting equipment, difficulty in achieving one-time molding, low construction efficiency, difficulty in protecting finished products, high safety risks associated with formwork, high costs due to material, labor, and machinery inputs.

[0003] To address the various problems arising from the construction method of using prefabricated wooden formwork, a formwork trolley (publication number CN106988314A) has been proposed in the prior art. This formwork trolley mainly consists of a main frame, moving parts, adjustment devices, and formwork. The adjustment devices enable the raising, lowering, and lateral movement of the formwork, thereby facilitating the adjustment of the formwork position, improving construction efficiency, reducing the input of mechanical equipment and manpower, and improving construction quality and safety.

[0004] However, existing formwork trolleys also have some obvious limitations. First, the formwork trolley requires an additional counterweight to maintain balance, which increases the overall weight, making movement and operation inconvenient and increasing the requirements for foundation bearing capacity, thus limiting its application in areas with poor foundation conditions or limited space. Second, due to the counterweight, the trolley occupies a large longitudinal space. In environments with limited construction space, such as narrow coastlines or areas near other structures, this further restricts the construction space, causing numerous difficulties in construction organization and operation. Furthermore, the main frame of the formwork trolley is a cantilever structure. To ensure overall structural balance, the cantilever section is relatively short in the longitudinal direction, resulting in fewer formwork panels connected to the cantilever section and smaller spacing between the formwork panels. This makes it unsuitable for casting columns with wide longitudinal cross-sections or for casting irregular cross-sections requiring more molds. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, one aspect of this application proposes a formwork trolley structure for cast-in-place concrete structures with irregular cross-sections, comprising:

[0007] Side trusses are used to install on existing ground structures; two side trusses are spaced apart along the longitudinal direction.

[0008] The top truss is arranged longitudinally; the two ends of the top truss are respectively located on top of the two side trusses.

[0009] Adjustment components are mounted on the top truss;

[0010] The template assembly is hoisted onto the adjustment assembly by a hoisting device, so as to move longitudinally under the drive of the adjustment assembly; there are multiple template assemblies, all located between two side trusses;

[0011] The tie-connector assembly has multiple components; both ends of the tie-connector assembly are respectively connected to two template components arranged opposite each other in the longitudinal direction; the template components are all connected to the side truss through the tie-connector assembly.

[0012] In the technical solution, the structural design forms a gantry structure through the side trusses and the top truss. Both sides of the gantry structure can be stably supported by the existing ground structure, which enables the formwork trolley of the gantry structure to stably bear the formwork components and related construction loads, providing stable support for the construction of the cast-in-place concrete structure, ensuring the structural stability during the construction process, and eliminating the need to set counterweights to improve the stability of the gantry structure, reducing the pressure on the existing ground structure, and enabling the existing ground structure to stably bear the poured concrete, preventing the existing ground structure from being damaged due to excessive pressure;

[0013] In the longitudinal direction, only the side truss occupies the ground space outside the construction area. There are no other structures outside the side truss, which makes the overall space occupied by the formwork trolley in the longitudinal direction less. Only a narrow space is needed outside the construction area to accommodate the side truss, so the formwork trolley of this application can be used to construct cast-in-place column concrete, thus meeting the construction needs of narrow spaces.

[0014] There is a large space between the two side trusses, which can accommodate multiple template components, meet the needs of irregular cross-sections that require a large number of template components, realize the cast-in-place column construction of irregular cross-section structures, and can also be applied to the casting of columns of structures with wider longitudinal cross-sections;

[0015] The tie rod connection assembly connects multiple formwork components to the side truss, making the entire formwork trolley system a whole. This enhances the coordination and stability between the components, effectively preventing the formwork from deforming, shifting, or overturning during concrete pouring, and ensuring the quality of concrete pouring and the dimensional accuracy of the structure.

[0016] In some embodiments, the regulating component includes:

[0017] A fixed base is fixedly installed on the top truss.

[0018] An adjustable seat is slidably mounted on the top truss; the lifting device connects to the adjustable seat;

[0019] The limiting connector has a fixed base and an adjusting base connected to its two ends respectively. The limiting connector is a telescopic structure, which is used to adjust the longitudinal position of the adjusting base by changing the length of the limiting connector.

[0020] In the technical solution, the structural design can flexibly adjust the position of the adjusting seat by changing the length of the limiting connector, thereby driving the template assembly to move longitudinally. This achieves precise positioning and adjustment of the template assembly in the longitudinal direction, meets the precise requirements of different construction sections for the template position, and improves the accuracy of construction and the level of quality control.

[0021] In some embodiments, the template component includes:

[0022] Support beams are installed vertically; multiple support beams are installed horizontally.

[0023] The tie beams are installed horizontally; the top of each support beam is connected to the tie beam, and the tie beams are connected to the lifting components.

[0024] Wooden beams are installed laterally; the wooden beams are connected to the side surface of the support beam away from the adjacent side truss.

[0025] The panel is vertically positioned on the side of the support beam away from the adjacent side truss; the wooden beam is connected to the panel on the side away from the support beam; multiple wooden beams are arranged vertically.

[0026] End plates are installed laterally; the two ends of the end plates are respectively connected to the bottom end of the support beam and the bottom end of the panel.

[0027] In this technical solution, the structural design features support beams arranged vertically and horizontally in multiple rows, forming a spatial frame structure. This structure can withstand the lateral pressure and vertical load generated during concrete pouring, providing stable lateral support for the panels, preventing panel deformation, and ensuring the appearance quality and dimensional accuracy of the concrete structure. By supporting the panels with wooden beams, the overall structural weight of the formwork assembly is reduced. Furthermore, construction workers can utilize the elasticity of the wood to slightly bend or compress it, allowing it to better conform to the panels and ensuring better lateral support. The lateral pressure and impact generated during concrete pouring can be buffered by the elasticity of the wooden beams, reducing rigid deformation of the panels.

[0028] In some embodiments, the pull-up connection assembly includes:

[0029] Tie rods are installed longitudinally and pass through corresponding template components;

[0030] Tie sleeves are fitted onto tie rods; at least two tie sleeves are provided, and both are attached to the surface of the corresponding template assembly near the adjacent side truss.

[0031] Pull nuts are threaded onto pull rods; pull nuts are attached to the side of the pull sleeve away from the corresponding template component.

[0032] In the technical solution, the structural design can firmly connect two longitudinally opposite template components with tie rods, stably maintain the spacing between the template components, and prevent the change in the spacing between the templates during concrete pouring from causing a decrease in structural accuracy; in addition, the tie rod nuts support the template components through tie rod sleeves, increasing the contact area and avoiding deformation of the template components due to single-point pressure concentration.

[0033] In some embodiments, the template component includes a first template component, a second template component, and a third template component;

[0034] The first template component, the second template component, and the third template component are arranged sequentially along the vertical direction;

[0035] The lower parts of the first template component and the third template component are positioned opposite each other, and a pull-out connection component is provided between the first template component and the third template component;

[0036] The upper parts of the second template component and the third template component are positioned opposite each other, and a pull-out connection component is provided between the second template component and the third template component;

[0037] The top of the second template assembly is connected to the top truss via anti-buoyancy top wires.

[0038] In the technical solution, the structural design uses three template components arranged at different heights to form an irregularly shaped stepped wave-breaking wall section, which meets the pouring requirements of the cross-section structure. The template components are connected by tie rods, and the middle template component is connected to the top truss by anti-buoyancy screws, which effectively prevents the template components from floating due to the buoyancy of the concrete during the concrete pouring process. This enhances the overall stability and anti-buoyancy of the template trolley, ensuring the safety of the construction process and the quality control of the concrete structure.

[0039] In some embodiments, a tie rod assembly is sequentially inserted through and connects the top of the first template assembly, the bottom of the second template assembly, and the middle of the third template assembly, and the two ends of the tie rod assembly are respectively connected to two side trusses.

[0040] In the technical solution, the structural design connects three formwork components simultaneously through a tie-connector, forming an integrated force-bearing system. This allows for force transmission between the formwork components, better resisting the various loads generated during concrete pouring and distributing them to each formwork component. Furthermore, the load can be further distributed to the side trusses, reducing the load pressure on individual formwork components and ensuring the lateral stability of the formwork system. In addition, the side trusses can constrain the three formwork components laterally through the tie-connector, ensuring the lateral stability of the formwork system.

[0041] In some embodiments, it further includes:

[0042] A cantilever beam is set laterally on the top truss; the formwork assembly includes an end formwork assembly; one end of the cantilever beam extends laterally to one side of the top truss and the end formwork assembly is hoisted by a hoisting device;

[0043] End support frame, for detachable installation on existing ground structure, with the side surface of the end formwork assembly away from the top truss attached to the end support frame.

[0044] In the technical solution, the structural design allows the end formwork assembly to be set at the end of the formwork trolley according to actual construction needs, meeting the pouring requirements of concrete structure ends of different lengths. The end support frame provides reliable support and positioning for the end formwork assembly, effectively preventing the end formwork assembly from shifting or deforming in the lateral direction, and ensuring the dimensional accuracy and appearance quality of the concrete structure ends.

[0045] In some embodiments, the end support frame includes:

[0046] The upright frame is installed vertically; the end mold assembly is attached to the upright frame.

[0047] The base frame is arranged horizontally, and the bottom end of the upright is connected to the end of the base frame near the end mold assembly;

[0048] The inclined support frame is set at an angle; one end of the inclined support frame is connected to the top of the upright frame, and the other end of the inclined support frame is connected to the end of the base frame away from the end mold assembly.

[0049] In the technical solution, the structure is designed so that the end support frame forms a stable triangular support structure, providing reliable support and resistance to lateral forces for the end formwork assembly, effectively preventing the end formwork assembly from overturning or deforming during concrete pouring, and ensuring the quality and safety of the concrete structure end.

[0050] In some embodiments, the bottom of the side truss is provided with wheels; the hoisting device is a hand-operated hoist.

[0051] In this technical solution, the structural design incorporates wheels, enabling the entire formwork trolley system to move and relocate easily within the construction site. This enhances the flexibility and mobility of the formwork trolley, allowing it to be quickly transferred to the next construction section without the need for large lifting equipment. This improves construction efficiency, reduces labor intensity and equipment usage costs, and better adapts to different construction processes and schedule requirements. Furthermore, construction personnel can easily use hand-operated hoists to hoist, lift, and lower formwork components, enabling rapid installation, disassembly, and adjustment of formwork components. This improves the convenience and efficiency of construction while reducing reliance on large lifting equipment and lowering construction costs.

[0052] In some embodiments, the bottom of the side trusses is spaced from the adjacent tie-connector assembly.

[0053] In the technical solution, the structural design avoids the load of concrete being transferred to the bottom of the side truss through the tie connection assembly, preventing excessive lateral pressure from causing deformation of the bottom of the side truss and avoiding damage to the traveling wheels due to lateral deformation of the side truss.

[0065] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0066] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0067] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0068] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0069] It should be noted that in the field of building structure construction, apart from rectangles, other shapes of concrete structure cross sections are generally referred to as irregular cross sections. The construction area for concrete pouring is located on the existing ground structure 100, which is usually a foundation laid or poured on the ground, or a concrete structure that has already been poured.

[0070] like Figures 1 to 3 As shown in the schematic embodiment of the formwork trolley structure for cast-in-place concrete structures with irregular cross-sections of this utility model, the formwork trolley structure for cast-in-place concrete structures with irregular cross-sections includes a side truss 200, a top truss 300, an adjustment component 400, a formwork component 500, and a tie-connection component 600.

[0071] The side trusses 200 are installed on the existing ground structure 100. There are two side trusses 200 arranged longitudinally, with the two side trusses 200 spaced apart. Construction passages are usually set up on both sides of the construction area to facilitate the transportation of materials and the movement of personnel. The construction area is located between the two side trusses 200, and the side trusses 200 are set on the construction passages.

[0072] The top truss 300 is arranged longitudinally, and its two ends are respectively connected to the top of the two side trusses 200, so that the two side trusses 200 jointly support the top truss 300. The top truss 300 and the two side trusses 200 form a gantry structure, and the construction area is located below the top truss 300.

[0073] An adjusting assembly 400 is mounted on the top truss 300, and the formwork assembly 500 is hoisted onto the adjusting assembly 400 via a hoisting component 700. The adjusting assembly 400 can move the formwork assembly 500 longitudinally, adjusting its longitudinal position. For pouring irregularly shaped concrete structures, multiple formwork assemblies 500 are used, each located between two side trusses 200, so that the two side trusses 200, together with the top truss 300, support all the formwork assemblies 500.

[0074] Formwork components 500 are typically arranged longitudinally opposite each other, with their bottom ends resting on the surface of the existing structure 100 on the ground, thus creating a space for pouring concrete between two opposing formwork components 500. Tie-connector components 600 connect to the two opposing formwork components 500 at both ends, preventing the two formwork components 500 from moving outwards after concrete is poured between them, maintaining the spacing between them, and ensuring the accuracy of the dimensions of the poured concrete structure. Since there are multiple formwork components 500, multiple tie-connector components 600 are arranged opposite each other, so that every pair of formwork components 500 is connected via tie-connector components 600. In addition, each formwork assembly 500 is connected to the side truss 200 through a tie-connector 600, so that the lateral load generated by the concrete acting on the formwork assembly 500 can be further transferred to the tie-connector 600. The side truss 200 can provide lateral support to the formwork assembly 500 through the tie-connector 600, thereby improving the stability of the formwork assembly 500 when supporting the concrete.

[0075] In this structural design, two side trusses 200 and a top truss 300 form a gantry structure. Both side trusses 200 on both sides of the gantry structure can be stably supported by the existing ground structure 100, thereby stably supporting the formwork assembly 500 and providing stable support for the construction of the cast-in-place concrete structure. Compared with the existing technology that uses counterweights to maintain balance, the gantry structure itself can maintain stability, avoiding the increase in pressure on the existing ground structure 100 due to the setting of counterweights. This allows the existing ground structure 100 to be used more to support the poured concrete, preventing the existing ground structure 100 from being damaged due to excessive pressure.

[0076] In the longitudinal direction, only the side truss 200 occupies the ground space outside the construction area. Compared with the existing technology where the main frame structure has counterweights on the side, the side truss 200 has no other structure on the outside, which makes the overall space occupied by the formwork trolley in the longitudinal direction less. Only a narrow space is needed outside the construction area to accommodate the side truss 200, so the formwork trolley of this application can be used to construct the cast-in-place column concrete, which meets the construction needs of narrow spaces.

[0077] Irregular cross-sections typically have multiple sides, requiring multiple formwork components 500 to form the casting space. The large space between the two side trusses 200 allows for the accommodation of multiple formwork components 500, meeting the requirement of a large number of formwork components 500 for irregular cross-sections and enabling cast-in-place column construction for such structures. Furthermore, the large space between the two side trusses 200 allows for a larger spacing between the formwork components 500, suitable for casting columns with wider longitudinal cross-sections.

[0078] Since the lifting component 700 cannot provide sufficient longitudinal support for the formwork assembly 500, the tie-connector 600 connects two opposing formwork assemblies 500, enabling the formwork assembly 500 to stably support the poured concrete laterally and maintain a stable spacing between the formwork assemblies 500. Furthermore, the tie-connector 600 connects to the side truss 200, allowing the lateral concrete load borne by each formwork assembly 500 to be transferred to the side truss 200, thus distributing the load, reducing the load on each formwork assembly 500, improving the stability of each formwork assembly 500, and also enhancing the overall structural stability of the formwork trolley, ensuring the quality and precision of the poured concrete structure.

[0079] See Figures 1 to 2 In some embodiments, the adjusting assembly 400 includes a fixed seat 401, an adjusting seat 402, and a limiting connector 403. The fixed seat 401 is typically fixed to the top truss 300 by bolts or welding. The adjusting seat 402 is slidably disposed on the top truss 300, allowing it to move longitudinally along the top truss 300. The top truss 300 typically uses the flange plates of the steel beams as guide rails or additional guide rails, and the adjusting seat 402 is slidably mounted on these guide rails, allowing it to slide along them. The limiting connector 403 is a telescopic structure, with its two ends connected to the fixed seat 401 and the adjusting seat 402, respectively. When the limiting connector 403 extends, the distance between the fixed seat 401 and the adjusting seat 402 increases; when the limiting connector 403 shortens, the distance between the fixed seat 401 and the adjusting seat 402 decreases. Furthermore, due to the fixed installation of the fastener, the change in the distance between the fixed seat 401 and the adjusting seat 402 causes the adjusting seat 402 to move longitudinally. The lifting component 700 connects to the adjusting seat 402, causing the template assembly 500 to move longitudinally along with the adjusting seat 402.

[0080] Furthermore, since there are multiple template components 500, each template component 500 is suspended on a corresponding adjusting seat 402. Multiple adjusting components 400 can be installed on the top truss 300; or, two adjusting seats 402 are respectively provided on both sides of the fixed seat 401 in the adjusting component 400, and the two adjusting seats 402 are connected to the same fixed seat 401 through a corresponding limiting connector 403. The aforementioned methods can provide multiple longitudinally movable adjusting seats 402 on the top truss 300 so that multiple template components 500 can be suspended and connected respectively.

[0081] Furthermore, the limiting connector 403 typically consists of a threaded sleeve and two adjusting screws connected by internal threads within the sleeve. The two adjusting screws are fixedly connected to the fixed seat 401 and the adjusting seat 402, respectively. Rotating the threaded sleeve allows the two adjusting screws to move towards each other or away from each other through the threaded engagement, changing the distance between the outer ends of the two adjusting screws and thus changing the length of the limiting connector 403, thereby achieving the extension and retraction of the limiting connector 403. The threaded connection also has a self-locking property, ensuring that the length of the limiting connector 403 remains fixed when the threaded sleeve is not being operated, keeping the adjusting seat 402 in its current longitudinal position. The limiting connector 403 can also be a push-pull rod, where the extension and retraction of the piston rod achieves the extension and retraction of the limiting connector 403.

[0082] This structural design changes the length of the limiting connector 403 and the longitudinal position of the adjusting seat 402, thereby driving the template assembly 500 to move longitudinally and changing its position in the longitudinal direction. This satisfies the size requirements of different concrete components and allows for fine-tuning of the longitudinal position of the template assembly 500. This enables precise positioning and adjustment of the template assembly 500 in the longitudinal direction, meeting the precise requirements of different construction sections for template position and improving the accuracy and quality control level of construction.

[0083] See Figure 2 In some embodiments, the template assembly 500 includes a support beam 501, a tie beam 502, a timber beam 503, a panel 504, and an end plate 505. The support beams 501 are vertically arranged, and multiple support beams 501 are arranged laterally. The tie beams 502 are arranged laterally, and the top ends of the support beams 501 are connected to the tie beams 502, forming a frame structure with the tie beams 502. The tie beams 502 are connected to a lifting device 700, allowing the lifting device 700 to lift the template assembly 500. The timber beams 503 are arranged laterally, with one side of the support beam 501 connected to one side of the timber beam 503, and the other side of the timber beam 503 connected to the panel 504. The panel 504 is vertically arranged, and multiple timber beams 503 are vertically arranged between the panel 504 and the support beams 501, so that the multiple support beams 501 laterally support the panel 504 through the multiple timber beams 503. The end plate 505 is arranged horizontally, and its two sides are respectively connected to the bottom end of the support beam 501 and the bottom end of the panel 504, thereby closing the bottom end of the space between the support beam 501 and the panel 504.

[0084] This structural design utilizes a frame structure composed of support beams 501 and tie beams 502. Multiple wooden beams 503 laterally support the panel 504. The frame structure possesses high strength, thus stably supporting the panel 504 and ensuring that the formwork assembly 500 can stably withstand the lateral pressure generated during concrete pouring. This prevents panel 504 deformation, maintains the flatness of the concrete surface, and ensures the accuracy of the concrete structure's dimensions by maintaining the longitudinal stability of the formwork assembly 500. Furthermore, the wooden beams 503 are made of wood, which is not only lightweight but also elastic, reducing the overall weight of the formwork assembly 500 and the load on the top truss 300. The wooden beams 503 can also undergo slight deformation, ensuring they adhere completely to the panel 504, providing ample support and guaranteeing the panel 504's stability. The elasticity of the wooden beams 503 also buffers the lateral pressure and impact generated during concrete pouring, further ensuring the stability of the panel 504 and preventing deformation caused by concrete impact.

[0085] See Figure 2 In some embodiments, the tie rod connection assembly 600 includes a tie rod 601, a tie sleeve 602, and a tie nut 603. The tie rod 601 is longitudinally arranged to pass through two template assemblies 500 respectively located on both sides and arranged opposite each other. The tie sleeve 602 is fitted around the tie rod 601, allowing the tie rod 601 to pass through the tie sleeve 602. Multiple tie sleeves 602 are provided, typically the number of tie sleeves 602 being the same as the number of template assemblies 500 through which the tie rod 601 passes. Each tie sleeve 602 is attached to the side surface of the corresponding template assembly 500 closest to the adjacent side truss 200, such that one side surface of the template assembly 500 faces another template assembly 500, and the other side surface is abutted by the tie sleeve 602, with each tie sleeve 602 positioned closer to the side truss 200. Pull nuts 603 are threaded onto pull rods 601. The number of pull nuts 603 is the same as the vertical number of pull sleeves 602. Each pull nut 603 is attached to a corresponding pull sleeve 602, so that one side of the pull sleeve 602 is against the template assembly 500, and the other side is against the pull nut 603. Concrete is poured between two opposing template assemblies 500. The pull nuts 603 laterally support the template assemblies 500 through the pull sleeves 602, maintaining the spacing between the template assemblies 500 and ensuring the accuracy of the dimensions of the poured concrete structure. This structural design can firmly pull together two longitudinally opposing template assemblies 500, stably maintaining the spacing between the template assemblies 500 and preventing changes in the spacing between the templates during concrete pouring that would lead to a decrease in structural accuracy. In addition, the pull nuts 603, by supporting the template assemblies 500 through the pull sleeves 602, increase the contact area and avoid deformation of the template assemblies 500 due to concentrated pressure at a single point.

[0086] Furthermore, when the template assembly 500 includes support beams 501, tie beams 502, wooden beams 503, panels 504, and end plates 505, the tie rods 601 pass through the gaps between adjacent support beams 501, the gaps between adjacent wooden beams 503, and the mounting holes provided in the panel 504. The two sides of the tie sleeves 602 are respectively attached to two adjacent support beams 501. This structural design eliminates the need for holes to be drilled in the support beams 501 and wooden beams 503 in the template assembly 500 to allow the tie rods 601 to pass through. The tie nuts 603 support the two support beams 501 through the tie sleeves 602, thus achieving longitudinal support of the support beams 501 by the tie nuts 603 even when they are not longitudinally aligned with the support beams 501.

[0087] See Figure 1 In some embodiments, the template assembly 500 includes a first template assembly 500A, a second template assembly 500B, and a third template assembly 500C. The first template assembly 500A, the second template assembly 500B, and the third template assembly 500C are arranged sequentially along the longitudinal direction, such that the first template assembly 500A and the third template assembly 500C are located on both sides of the construction area, and the second template assembly 500B is located in the middle of the construction area.

[0088] The lower parts of the first template component 500A and the third template component 500C are arranged opposite each other, and the upper parts of the second template component 500B and the third template component 500C are arranged opposite each other, so that the first template component 500A and the second template component 500B are set at different heights. A tie-connector component 600 is provided between the first template component 500A and the third template component 500C to connect them. A tie-connector component 600 is also provided between the second template component 500B and the third template component 500C to connect them. The top of the second template component 500B is connected to the top truss 300 through an anti-buoyancy top screw 800.

[0089] The structural design uses a staggered arrangement of the first template component 500A and the second template component 500B, one at a lower height and the other at a higher height, to create a stepped concrete pouring space between them and the third template, thus meeting the requirements for forming an irregular cross-section of the wave barrier wall. The opposing template components 500 are connected by tie rods 600, and both the first template component 500A and the second template component 500B are connected to the third template component 500C, forming a unified structure. The second template component 500B in this unified structure is connected to the top truss 300 via anti-buoyancy screws 800, effectively preventing the individual template components 500 from floating due to the buoyancy of the concrete during pouring. Each template component 500 remains vertically stable, preventing gaps between the template component 500 and the existing ground structure 100 caused by floating, thus preventing concrete leakage and ensuring the quality of the poured concrete structure. In addition, the anti-buoyancy top wire 800 connects to the second template assembly 500 located in the middle, so that the top truss 300 forms uniform vertical support for the overall structure composed of each template assembly 500 through the anti-buoyancy top wire 800, ensuring the vertical stability of each template assembly 500 in the overall structure.

[0090] Furthermore, the bottom end of the second template component 500B is located above the space between the first template component 500A and the third template component 500C. When the template component 500 includes a support beam 501, a tie beam 502, a wooden beam 503, a panel 504, and an end plate 505, the end plate 505 closes the bottom structure of the second template component 500B. The concrete poured between the first template component 500A and the third template component 500C rises and adheres to the end plate 505 at the bottom of the second template component 500B, ensuring the formation of the concrete structure step surface.

[0091] See Figure 1In some embodiments, a tie-connector 600 sequentially passes through and connects the top of the first template assembly 500A, the bottom of the second template assembly 500B, and the middle of the third template assembly 500C, with both ends of the tie-connector 600 connected to two side trusses 200 respectively. This structural design allows a tie-connector 600 to simultaneously pass through the first template assembly 500A, the second template assembly 500B, and the third template assembly 500C, forming a unified load-bearing system. This enables the three template assemblies 500 to provide longitudinal support through the same tie-connector 600, distributing the various loads generated during concrete pouring to each template assembly 500, reducing the load borne by each template assembly 500 individually, and improving the stability of the template system. The tie-connector 600 connects the three formwork components 500 and further connects the two side trusses 200, distributing the load further across the two side trusses 200. The stable side trusses 200 further support the three formwork components 500, thereby enhancing the stability of the formwork system. Additionally, the side trusses 200, through the tie-connector 600, can constrain the three formwork components 500 laterally, ensuring the lateral stability of the formwork system.

[0092] Furthermore, when the pull connection assembly 600 includes a pull screw 601, a pull sleeve 602, and a pull nut 603, the pull connection assembly 600 that simultaneously connects the three template assemblies 500 includes three pull sleeves 602 and three pull nuts 603. The first tie sleeve 602 and the corresponding first tie nut 603 are located on the side of the first template assembly 500 away from the third template assembly 500; the second tie sleeve 602 and the corresponding second tie nut 603 are located on the side of the second template assembly 500 away from the third template assembly 500; the third tie sleeve 602 and the corresponding third tie nut 603 are located on the side of the third template assembly 500 away from the first template assembly 500 and the second template assembly 500, so that the first template assembly 500 and the second template assembly 500 are both connected to the third template assembly 500 by the tie connection assembly 600, and the pouring space is formed between the first template assembly 500 and the third template assembly 500 and between the second template assembly 500 and the third template assembly 500, and the tie sleeve 602 and the tie nut 603 do not encroach on the space for concrete pouring.

[0093] See Figures 1 to 3In some embodiments, the formwork trolley structure of the irregular cross-section cast-in-place concrete structure further includes a cantilever beam 900 and an end support frame 1000. The cantilever beam 900 is arranged laterally and is mounted on the top truss 300. One end of the cantilever beam 900 extends laterally to one side of the top truss 300, such that the portion of the cantilever beam 900 extending beyond the top truss 300 is a cantilever portion. The end formwork assembly 500D among the multiple formwork assemblies 500 is hoisted onto the cantilever portion of the cantilever beam 900 by a hoisting device 700, such that the end formwork assembly 500D is located on one side of the gantry structure formed by the side truss 200 and the top truss 300 in the lateral direction. The formwork assembly 500 located inside the gantry structure forms a concrete pouring space in the longitudinal direction. The lateral port of the concrete pouring space is closed by the end formwork assembly 500D, such that the formwork assembly 500 surrounds a concrete pouring space with its bottom supported by the existing ground structure 100 and its top open in both the lateral and longitudinal directions. When the cross-section of the concrete component to be poured is wide in the longitudinal direction, multiple cantilever beams 900 are usually set in the longitudinal direction, and multiple cantilever beams 900 are used to lift the same end formwork assembly 500D through the lifting component 700.

[0094] The end support frame 1000 is detachably mounted on the existing ground structure 100. The side surface of the end formwork assembly 500D away from the top truss 300 is attached to the end support frame 1000, so that the end support frame 1000 supports the end formwork assembly 500D in the lateral direction, ensuring that the end formwork assembly 500D remains stable under the action of concrete load.

[0095] This structural design allows the end formwork assembly 500D to be positioned at the end of the formwork trolley according to actual construction needs, meeting the pouring requirements of concrete structure ends of different lengths. The end support frame 1000 provides reliable support and positioning for the end formwork assembly 500D, effectively preventing the end formwork assembly 500D from shifting or deforming in the lateral direction, and ensuring the dimensional accuracy and appearance quality of the concrete structure ends.

[0096] Furthermore, the wave-breaking wall is typically poured in sections along the transverse direction. When pouring the first section, one end of the concrete pouring space formed by the formwork assembly 500 inside the gantry structure is usually closed by a fixedly installed end formwork assembly 500D, while the other end is closed by an end formwork assembly 500D suspended from the cantilever beam 900. After the first section of concrete structure is poured, the gantry structure moves laterally to the next construction position. The completed concrete structure is then used to close one end of the concrete pouring space formed by the formwork assembly 500 inside the gantry structure, while the other end is still closed by the end formwork assembly 500D suspended from the cantilever beam 900. This structural design allows the formwork trolley to only need to install the cantilever beam 900 and end formwork assembly 500D at one end, reducing both the manufacturing cost and weight of the formwork trolley and facilitating its transport.

[0097] See Figure 3 In some embodiments, the end support frame 1000 includes an upright frame 1001, a base frame 1002, and a diagonal brace 1003. The upright frame 1001 is vertically arranged, and the end formwork assembly 500D is attached to the upright frame 1001. The base frame 1002 is horizontally arranged, and the bottom end of the upright frame 1001 is connected to the end of the base frame 1002 near the end formwork assembly 500D. The diagonal brace 1003 is inclined relative to the horizontal plane, with one end of the diagonal brace 1003 connected to the top end of the upright frame 1001, and the other end of the diagonal brace 1003 connected to the end of the base frame 1002 away from the end formwork assembly 500D. This structural arrangement makes the end support frame 1000 form a stable triangular support structure, providing reliable support and resistance to lateral forces for the end formwork assembly 500D, effectively preventing the end formwork assembly 500D from overturning or deforming during concrete pouring, and ensuring the quality and safety of the end of the concrete structure.

[0098] In some implementations, the bottom of the side truss 200 is equipped with traveling wheels 1100, which allow the mold trolley to move laterally. After pouring one section of concrete, it can be moved to the next construction position for pouring the next section. The hoisting component 700 is a hand-operated hoist. By operating the hand-operated hoist, the formwork assembly 500 can be raised or lowered, and its vertical position can be adjusted. After pouring one end of the concrete structure, the formwork assembly 500 can be raised by operating the hand-operated hoist, which can release the formwork assembly 500 from the existing ground structure 100, allowing the mold trolley to move laterally.

[0099] This structural design, with its 1100 wheels, allows the entire formwork trolley system to be easily moved and relocated within the construction site, enhancing the flexibility and mobility of the formwork trolley. It enables rapid transfer of the formwork trolley to the next construction section without the need for large lifting equipment, improving construction efficiency, reducing labor intensity and equipment usage costs, and better adapting to different construction processes and schedule requirements. Furthermore, construction personnel can easily perform hoisting, lifting, and lowering operations on the formwork components 500 using hand-operated hoists, enabling rapid installation, disassembly, and adjustment of the formwork components 500. This improves construction convenience and efficiency while reducing reliance on large lifting equipment and lowering construction costs.

[0100] In some embodiments, the bottom of each side truss 200 is spaced from the adjacent tie-connector 600, such that the tie-connector 600 located at the bottom of the space between two side trusses 200 is not connected to the side truss 200. Since the bottom of the side truss 200 contacts the existing ground structure 100 via the wheels 1100, and the existing ground structure 100 provides insufficient longitudinal support to the bottom of the side truss 200 through friction, this structural design prevents the lateral load of the concrete from being transferred to the bottom of the side truss 200 through the tie-connector 600. This also prevents the bottom of the side truss 200 from deforming longitudinally in the event of a large longitudinal load on the bottom of the side truss 200 and insufficient longitudinal support from the existing ground structure 100, thus preventing the wheels 1100 from shifting to one side and further bending and damaging the truss structure under its weight. In addition, the traveling wheels 1100 are usually located in the rails installed on the existing ground structure 100. Reducing the load on the bottom of the side truss 200 can reduce the pressure of the traveling wheels 1100 on the side of the rail, prevent the rail from deforming, and ensure smooth lateral movement of the template trolley.
