Abstract
Description
Technical Field
[0001] This utility model relates to the field of wharf construction technology, and in particular to a cantilevered formwork support. Background Technology
[0002] During wharf construction, it is often necessary to cast-in-place berthing components. Therefore, formwork needs to be erected at the wharf's front edge (the seaward side) before the berthing components are poured. Since the lower part of the wharf's front edge is sea area, it is impossible to erect formwork supports from the bottom up. Currently, commonly used methods include a reverse-lifting system for high-pile wharves disclosed in Chinese Utility Model Patent No. CN211849246U. This system uses main beams and reverse-lifting screws to support brackets, ensuring the stability and integrity of the superstructure and guaranteeing the construction progress of the pre-cast tie beams and panels of the high-pile wharf.
[0003] However, it is not difficult to see that although using this traditional reverse hoisting system to install formwork can overcome the problem that formwork supports cannot be erected at the front of the wharf, this traditional reverse hoisting system has a complex structure, is difficult to construct, and is difficult to dismantle the formwork later, which greatly slows down the on-site construction progress. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of existing cantilever formwork support systems, such as complex structure, high construction difficulty, and difficult dismantling, and to provide a cantilever formwork support.
[0005] In a first aspect, the present invention provides a cantilevered formwork support, comprising: a longitudinal beam; a cantilever, one end of which is fixedly connected to one end of the longitudinal beam, the other end of which is cantilevered, and a first mounting hole being provided at the end of the longitudinal beam near the cantilever; a first diagonal brace, one end of which is fixedly connected to the longitudinal beam, and the other end of which is fixedly connected to the cantilever; and a formwork connecting component disposed at the cantilevered end of the cantilever.
[0006] The cantilevered formwork support provided by this utility model has mounting holes at the end of the longitudinal beam near the cantilever, allowing for quick and detachable connection to the wharf facade via bolts or other connectors, providing a stable anchor point for the support. The cantilever supports the formwork; after the formwork is installed and concrete is poured, the upper part of the longitudinal beam is fixed to the wharf facade with bolts. At this point, the cantilever provides a force to the end of the longitudinal beam away from the mounting holes, ensuring a tight connection between the longitudinal beam and the wharf facade, thereby enhancing the overall stability of the support.
[0007] The first diagonal brace, together with the longitudinal beam and the cantilever, forms a stable triangular support structure, which can effectively distribute the load on the cantilever (such as the weight of the formwork and the pressure of concrete pouring), significantly improving the overturning resistance and overall stability of the support. The cantilever end of the cantilever is equipped with a formwork connection component, which facilitates the quick assembly and disassembly of the side formwork, simplifies the formwork installation and disassembly process, and thus improves construction efficiency.
[0008] This cantilevered formwork support system features a simple design and is easy to install, requiring only one fixed anchor point for connection to the wharf's exterior. In use, multiple supports can be spaced out along the wharf's extension direction, and formwork can be installed on these supports, flexibly adapting to different construction needs. This support system can bear the loads of the formwork and concrete without requiring underlying support, making it particularly suitable for environments like the seaside of a wharf where the seabed is below and traditional supports are not feasible. It provides an efficient and safe solution for the construction of cast-in-place berthing components at the wharf's front edge.
[0009] Preferably, the cantilever includes an inclined arm and a horizontal arm, one end of the inclined arm is fixedly connected to the longitudinal beam, the other end of the inclined arm is fixedly connected to the horizontal arm, the angle between the inclined arm and the longitudinal beam is an obtuse angle, the end of the horizontal arm away from the inclined arm is cantilevered, the template connecting component is disposed on the horizontal arm, one end of the first diagonal brace is fixedly connected to the longitudinal beam, and the other end of the first diagonal brace is fixedly connected to the inclined arm.
[0010] The obtuse angle design between the inclined arm and the longitudinal beam allows the cantilever to transfer some of the vertical force to the longitudinal beam through the inclined path when bearing loads (such as the weight of the formwork and concrete), further securing the longitudinal beam to the exterior of the wharf. This force transfer method effectively reduces the bending moment at the root of the cantilever and minimizes stress concentration. Compared to traditional horizontal cantilever designs, this structure more rationally distributes the load and improves the load-bearing capacity of the support frame.
[0011] The horizontal arm ensures that the formwork connection components are in a horizontal position, which facilitates the precise installation of the formwork and the uniform pouring of concrete, thus guaranteeing the quality of the pouring. On the other hand, since the horizontal arm is in a horizontal position after installation, walkways for construction workers can be erected on the horizontal arms of two adjacent cantilevered formwork supports, which facilitates the installation of formwork by construction workers.
[0012] The first diagonal brace connects to the longitudinal beam at one end and the inclined arm at the other. Together with the fixed connection between the inclined arm and the longitudinal beam, they form a stable triangular support structure. This triangular design has high stiffness and anti-overturning capacity, effectively resisting vertical and horizontal loads on the cantilever and significantly improving the overall stability of the support.
[0013] Preferably, it further includes a second diagonal brace, one end of which is fixedly connected to the first diagonal brace, and the other end of which is fixedly connected to the inclined arm or longitudinal beam.
[0014] The addition of the second diagonal brace provides an extra support point to the existing triangular support formed by the first diagonal brace and the cantilever. By connecting one end to the first diagonal brace and the other end to the inclined arm or longitudinal beam, a more stable support system is formed. This design significantly improves the overall rigidity of the support structure and effectively reduces deformation and vibration caused by external loads (such as wind or construction loads).
[0015] Preferably, the cantilever includes: a first horizontal arm, a second horizontal arm, a vertical arm, and a second diagonal brace; one end of the first horizontal arm is fixedly connected to the longitudinal beam, the other end of the first horizontal arm is fixedly connected to the vertical arm, the end of the vertical arm away from the first horizontal arm is fixedly connected to the second horizontal arm, and the end of the second horizontal arm away from the vertical arm is cantilevered; the template connecting component is disposed on the second horizontal arm; one end of the first diagonal brace is fixedly connected to the longitudinal beam, and the other end of the first diagonal brace is fixedly connected to the first horizontal arm; one end of the second diagonal brace is fixedly connected to the cantilevered end of the second horizontal arm, and the other end of the second horizontal arm is fixedly connected to the vertical arm or the first horizontal arm.
[0016] With this structural setup, the vertical arm is perpendicular to the first and second horizontal arms, which facilitates the installation of the bottom and side forms of the cast-in-place berthing components, making it easier to pour concrete later.
[0017] The template connecting component is set on the second horizontal arm, which can set up a walkway for construction workers to walk on the second horizontal arm of two adjacent cantilevered template supports, making it convenient for construction workers to install templates;
[0018] The first diagonal brace connects the longitudinal beam and the first horizontal arm, forming a triangular support structure. This enhances the overturning resistance of the first horizontal arm and reduces deformation caused by load. The second diagonal brace connects the cantilever end of the second horizontal arm to the vertical arm or the first horizontal arm, providing additional support to the cantilever end. This effectively suppresses sagging and vibration at the cantilever end, further consolidating the stability of the support structure.
[0019] Preferably, the system further includes a third diagonal brace, one end of which is fixedly connected to the first diagonal brace, and the other end of which is fixedly connected to the first horizontal arm or longitudinal beam.
[0020] The third diagonal brace connects the first diagonal brace and the first horizontal arm or longitudinal beam, forming a more stable support frame together with the original structure. The newly added support points significantly improve the overall rigidity of the support structure, effectively reducing deformation and vibration caused by external loads (such as wind or construction loads).
[0021] Preferably, the cantilever includes: a first horizontal arm, a second horizontal arm, a vertical arm, and an inclined arm; one end of the first horizontal arm is fixedly connected to the longitudinal beam, the other end of the first horizontal arm is fixedly connected to the vertical arm, the end of the vertical arm away from the first horizontal arm is fixedly connected to the inclined arm, the end of the inclined arm away from the vertical arm is fixedly connected to the second horizontal arm, and the end of the second horizontal arm away from the inclined arm is cantilevered; one end of the first diagonal brace is fixedly connected to the longitudinal beam, and the other end of the first diagonal brace is fixedly connected to the inclined arm; the angle between the inclined arm and the longitudinal beam is an obtuse angle; the template connecting component is disposed on the second horizontal arm.
[0022] This structural design creates a multi-layered support structure, effectively distributing the loads of the formwork and concrete, preventing any single component from bearing excessive pressure, and thus enhancing the overall stability of the support system. Specifically, the obtuse angle design between the inclined arm and the longitudinal beam allows the second horizontal arm and the inclined arm to transfer some of the vertical force (such as the weight of the formwork and concrete) to the first horizontal arm through an inclined path when bearing loads. The first horizontal arm and the inclined arm are connected by a vertical arm, which provides vertical support. One end of the first horizontal arm is fixedly connected to the longitudinal beam, and the other end is connected to the vertical arm, serving as the horizontal foundation of the entire cantilever structure. It not only supports the vertical arm and the second horizontal arm but also transfers the loads of the formwork and concrete to the longitudinal beam, ultimately distributing them to the exterior of the wharf and ensuring the overall stability of the support system.
[0023] The first diagonal brace is fixed at one end to the longitudinal beam and at the other end directly to the inclined arm, forming a stable triangular support structure together with the longitudinal beam and the inclined arm. This triangular design significantly improves the overturning resistance of the support, especially when subjected to wind loads or construction loads, effectively reducing structural deformation and vibration.
[0024] This multi-layered support and optimized mechanical design provides construction workers with greater safety and reduces the risk of accidents caused by support failure.
[0025] Preferably, the end of the first horizontal arm away from the longitudinal beam abuts against the first diagonal brace.
[0026] The contact between the first horizontal arm and the first diagonal brace provides an additional support point at the far end of the first horizontal arm, allowing the load to be directly transferred from the first horizontal arm to the first diagonal brace, and then from the first diagonal brace to the longitudinal beam. This support significantly improves the bending and shear resistance of the first horizontal arm, especially when bearing external loads such as formwork and concrete, reducing deformation and thus ensuring the stability of the entire support structure.
[0027] Preferably, the template connecting component includes a first connecting plate and a second connecting plate, the first connecting plate being fixedly connected to the cantilever, the second connecting plate being fixedly connected to the first connecting plate, and the second connecting plate having a second mounting hole.
[0028] With this structural design, the fixed connection between the first connecting plate and the cantilever ensures the stability of the installed template, while the second mounting hole on the second connecting plate provides a convenient installation point for the template. Construction workers can quickly fix and disassemble the template using bolts and other fasteners, improving the efficiency of template installation and disassembly.
[0029] Preferably, the angle between the tilting arm and the longitudinal beam is 100°~130°.
[0030] Setting the angle between the tilting arm and the longitudinal beam to 100°~130° allows the tilting arm to transfer the load to the longitudinal beam at a relatively gentle angle, reducing the bending moment and shear force at the root of the cantilever (where it connects to the longitudinal beam) and reducing stress concentration.
[0031] Preferably, a guardrail socket is provided at the cantilever end of the cantilever.
[0032] With this structural design, the cantilevered end of the cantilever is located at a high altitude, potentially above the sea or open space, posing a risk of fall for construction workers installing formwork, pouring concrete, or performing other operations. The guardrail socket allows for the installation of guardrails; by installing guardrails between adjacent formwork supports, a physical barrier can be formed, effectively preventing accidental falls and significantly improving construction safety.
[0033] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0034] 1. This utility model provides a cantilevered formwork support. The longitudinal beam has mounting holes at one end near the cantilever, allowing for quick and detachable connection to the wharf facade via bolts or other connectors, providing a stable anchor point for the support. The cantilever supports the formwork. After the formwork is installed and concrete is poured, the upper part of the longitudinal beam is fixed to the wharf facade with bolts. At this time, the cantilever provides a force to the end of the longitudinal beam away from the mounting holes, ensuring a tight connection between the longitudinal beam and the wharf facade, thereby enhancing the overall stability of the support.
[0035] 2. This utility model provides a cantilevered formwork support. The first diagonal brace, together with the longitudinal beam and the cantilever, forms a stable triangular support structure, which can effectively distribute the load on the cantilever (such as the weight of the formwork and the pressure of concrete pouring), significantly improving the overturning resistance and overall stability of the support. The cantilever end of the cantilever is provided with a formwork connection component, which facilitates the quick assembly and disassembly of the side formwork, simplifies the installation and disassembly process of the formwork, and thus improves construction efficiency.
[0036] 3. This utility model provides a cantilevered formwork support, which is simple in design and easy to install, requiring only one fixed anchor point for connection to the exterior of the wharf. In use, multiple supports can be spaced apart along the wharf's extension direction, and formwork can be installed on the supports, flexibly adapting to different construction needs. This support can bear the load of the formwork and concrete without requiring lower support, making it particularly suitable for environments where the wharf's seaward side faces the sea and traditional supports cannot be erected. It provides an efficient and safe solution for the construction of cast-in-place berthing components at the wharf's front edge. Attached Figure Description

[0049] Example 1
[0050] This embodiment provides a cantilevered formwork support, which can be bolted to the seaward side of the pier facade to provide support for the cast-in-place berthing component formwork.
[0051] Specifically, the cantilevered formwork support provided in this embodiment includes: a longitudinal beam 1, which can be made of channel steel structural components, and the longitudinal beam 1 is used for detachable connection with the exterior facade of the dock.
[0052] Cantilever 2, one end of which is fixedly connected to one end of longitudinal beam 1, and the other end of cantilever 2 is overhanging. Longitudinal beam 1 is used for installing formwork. Figure 1 As shown, a first mounting hole 11 is opened at one end of the longitudinal beam 1 near the cantilever 2, through which the longitudinal beam 1 can be bolted to the outer facade of the dock.
[0053] The first diagonal brace 3 has one end fixedly connected to the longitudinal beam 1, for example, it can be welded to the middle of the first diagonal brace 3, and the other end fixedly connected to the cantilever 2.
[0054] Template connecting component 4 is located at the cantilever end of cantilever 2 and is used to connect the side mold.
[0055] The cantilevered formwork support provided in this embodiment has an installation hole at the end of the longitudinal beam 1 near the cantilever 2, which allows for quick and detachable connection to the wharf facade via bolts or other connectors, providing a stable anchor point for the support. The cantilever 2 supports the formwork. After the formwork is installed and concrete is poured, the upper part of the longitudinal beam 1 is fixed to the wharf facade with bolts. At this time, the cantilever 2 provides a force to the end of the longitudinal beam 1 away from the installation hole, ensuring a tight connection between the longitudinal beam 1 and the wharf facade, thereby enhancing the overall stability of the support. The first diagonal brace 3, together with the longitudinal beam 1 and the cantilever 2, forms a stable triangular support structure, effectively distributing the load on the cantilever 2 (such as the weight of the formwork and the pressure of concrete pouring), significantly improving the support's anti-overturning ability and overall stability. The cantilever end of the cantilever 2 is equipped with a formwork connection component 4, facilitating quick assembly and disassembly of the side formwork, simplifying the formwork installation and disassembly process, and thus improving construction efficiency.
[0056] This cantilevered formwork support system features a simple design and is easy to install, requiring only one fixed anchor point for connection to the wharf's exterior. In use, multiple supports can be spaced out along the wharf's extension direction, and formwork can be installed on these supports, flexibly adapting to different construction needs. This support system can bear the loads of the formwork and concrete without requiring underlying support, making it particularly suitable for environments like the seaside of a wharf where the seabed is below and traditional supports are not feasible. It provides an efficient and safe solution for the construction of cast-in-place berthing components at the wharf's front edge.
[0057] Example 2
[0058] Based on Example 1, this example further explains the specific structure of the cantilever 2, such as... Figure 1 As shown, in this embodiment, the cantilever 2 includes an inclined arm 21 and a horizontal arm 22. One end of the inclined arm 21 is fixedly connected to the longitudinal beam 1, and the other end of the inclined arm 21 is fixedly connected to the horizontal arm 22. The angle between the inclined arm 21 and the longitudinal beam 1 (e.g., Figure 1 In the middle, ∠α) is an obtuse angle. Specifically, the angle between the inclined arm 21 and the longitudinal beam 1 is 100°~130°.
[0059] The horizontal arm 22 is cantilevered at one end away from the inclined arm 21. The template connecting component 4 is set on the horizontal arm 22. One end of the first diagonal brace 3 is fixedly connected to the longitudinal beam 1, and the other end of the first diagonal brace 3 is fixedly connected to the inclined arm 21.
[0060] Furthermore, in this embodiment or other embodiments, a guardrail socket 7 can be provided at the cantilever end of the cantilever 2, specifically, as shown below. Figure 1 As shown, the guardrail socket 7 can be an upward-facing square steel bar into which the guardrail can be inserted. The guardrail socket 7 can be installed at the cantilever end of the horizontal arm 22. The cantilever end of the cantilever 2 is located at a high altitude, and below it may be the sea or an open area, posing a risk of fall for construction workers when installing formwork, pouring concrete, or performing other operations. The guardrail socket 7 allows for the installation of guardrails; by installing guardrails between two adjacent formwork supports, a physical barrier can be formed, effectively preventing accidental falls and significantly improving the construction safety factor.
[0061] Furthermore, such as Figure 2 As shown in this embodiment or other embodiments, the template connecting component 4 includes a first connecting plate 41 and a second connecting plate 42. The first connecting plate 41 is fixedly connected to the cantilever 2, and the second connecting plate 42 is fixedly connected to the first connecting plate 41. Specifically, the second connecting plate 42 can be welded to the first connecting plate 41, and the second connecting plate 42 can be perpendicular to the first connecting plate 41. A third connecting plate 43 can be further welded between the second connecting plate 42 and the first connecting plate 41. The third connecting plate 43 can be a right triangle and is used to reinforce the connection between the second connecting plate 42 and the first connecting plate 41. The second connecting plate 42 has a second mounting hole 421. The fixed connection between the first connecting plate 41 and the cantilever 2 ensures the stability of the installed template. The second mounting hole 421 on the second connecting plate 42 provides a convenient installation point for the template. Construction workers can quickly complete the fixing and disassembly of the template using bolts and other fasteners, improving the efficiency of template installation and disassembly.
[0062] Furthermore, such as Figure 1As shown, in this embodiment or other embodiments, a reinforcing plate 8 can be welded to the fixed connection point between the first diagonal brace 3 and the cantilever 2 to further strengthen the connection between the first diagonal brace 3 and the cantilever 2.
[0063] Furthermore, such as Figure 1 As shown, the cantilevered formwork support also includes a second diagonal brace 5. One end of the second diagonal brace 5 is fixedly connected to the first diagonal brace 3, specifically, it can be welded to the middle of the first diagonal brace 3. The other end of the second diagonal brace 5 is fixedly connected to the inclined arm 21 or the longitudinal beam 1, preferably welded to the end of the inclined arm 21 near the longitudinal beam 1 or the end of the longitudinal beam 1 near the inclined arm 21. The addition of the second diagonal brace 5 adds an extra support point to the triangular support formed by the original first diagonal brace 3 and the cantilever 2. By connecting one end to the first diagonal brace 3 and the other end to the inclined arm 21 or the longitudinal beam 1, a more stable support system is formed. This design significantly improves the overall rigidity of the support and effectively reduces deformation and vibration caused by external loads (such as wind or construction loads).
[0064] The cantilevered formwork support provided in this embodiment features an obtuse angle design between the inclined arm 21 and the longitudinal beam 1. This design allows the cantilever 2, when bearing loads (such as the weight of the formwork and concrete), to transfer a portion of the vertical force to the longitudinal beam 1 via an inclined path, further securing the longitudinal beam 1 against the outer facade of the wharf. This force transfer method effectively reduces the bending moment at the root of the cantilever 2 and minimizes stress concentration. Compared to traditional horizontal cantilever designs, this structure more rationally distributes the load and enhances the support's load-bearing capacity.
[0065] The horizontal arm 22 ensures that the formwork connection component 4 is in a horizontal state, which facilitates the precise installation of the formwork and the uniform pouring of concrete, thus ensuring the quality of the pouring. On the other hand, since the horizontal arm 22 is in a horizontal state after installation, a walkway for construction workers to walk on can be set up on the horizontal arms 22 of two adjacent cantilevered formwork supports, which facilitates the installation of formwork by construction workers.
[0066] The first diagonal brace 3 is connected at one end to the longitudinal beam 1 and at the other end to the inclined arm 21. Together with the fixed connection between the inclined arm 21 and the longitudinal beam 1, they form a stable triangular support structure. This triangular design has high stiffness and anti-overturning capacity, effectively resisting vertical and horizontal loads on the cantilever 2 and significantly improving the overall stability of the support.
[0067] Example 3
[0068] Based on Example 1, this example further explains the specific structure of the cantilever 2, such as... Figure 3 As shown, cantilever 2 includes:
[0069] First horizontal arm 221, second horizontal arm 222, vertical arm 23 and second diagonal brace 5;
[0070] One end of the first horizontal arm 221 is fixedly connected to the longitudinal beam 1, and the other end of the first horizontal arm 221 is fixedly connected to the vertical arm 23. The end of the vertical arm 23 away from the first horizontal arm 221 is fixedly connected to the second horizontal arm 222. The end of the second horizontal arm 222 away from the vertical arm 23 is cantilevered. Specifically, the first horizontal arm 221 and the second horizontal arm 222 can be parallel to each other, the vertical arm 23 is perpendicular to the first horizontal arm 221 and the second horizontal arm 222, and the vertical arm 23 is parallel to the longitudinal beam 1.
[0071] Template connecting component 4 is disposed on the second horizontal arm 222;
[0072] One end of the first diagonal brace 3 is fixedly connected to the longitudinal beam 1, and the other end of the first diagonal brace 3 is fixedly connected to the first horizontal arm 221.
[0073] One end of the second diagonal brace 5 is fixedly connected to the cantilever end of the second horizontal arm 222, and the other end of the second horizontal arm 222 is fixedly connected to the vertical arm 23 or the first horizontal arm 221.
[0074] Furthermore, such as Figure 3 As shown, the cantilevered formwork support also includes a third diagonal brace 6. One end of the third diagonal brace 6 is fixedly connected to the first diagonal brace 3, and the other end is fixedly connected to the first horizontal arm 221 or the longitudinal beam 1. The third diagonal brace 6, by connecting the first diagonal brace 3 and the first horizontal arm 221 or the longitudinal beam 1, together with the original structure, forms a more stable support frame. The newly added support points significantly improve the overall rigidity of the support, effectively reducing deformation and vibration caused by external loads (such as wind or construction loads).
[0075] Furthermore, such as Figure 3 As shown, in this embodiment or other embodiments, a reinforcing plate 8 can be welded to the fixed connection point between the first horizontal arm 221 and the vertical arm 23, a reinforcing plate 8 can be welded to the fixed connection point between the first diagonal brace 3 and the first horizontal arm 221, and a reinforcing plate 8 can be welded to the fixed connection point between the third diagonal brace 6 and the first horizontal arm 221.
[0076] The cantilevered formwork support provided in this embodiment has an upright arm 23 perpendicular to the first horizontal arm 221 and the second horizontal arm 222, which facilitates the installation of the bottom and side forms of the cast-in-place berthing components, making subsequent concrete pouring easier. The formwork connecting component 4 is located on the second horizontal arm 222, allowing the construction workers to walk along the second horizontal arms 222 of adjacent cantilevered formwork supports, facilitating formwork installation. The first diagonal brace 3 connects the longitudinal beam 1 and the first horizontal arm 221, forming a triangular support structure that enhances the overturning resistance of the first horizontal arm 221 and reduces deformation caused by load. The second diagonal brace 5 connects the cantilever end of the second horizontal arm 222 to the upright arm 23 or the first horizontal arm 221, providing additional support to the cantilever end, effectively suppressing sagging and vibration, and further consolidating the stability of the support.
[0077] Example 4
[0078] Based on Example 1, this example further explains the specific structure of the cantilever 2, such as... Figure 4 As shown, cantilever 2 includes:
[0079] First horizontal arm 221, second horizontal arm 222, vertical arm 23 and inclined arm 21;
[0080] One end of the first horizontal arm 221 is fixedly connected to the longitudinal beam 1, and the other end of the first horizontal arm 221 is fixedly connected to the vertical arm 23. The end of the vertical arm 23 away from the first horizontal arm 221 is fixedly connected to the inclined arm 21, and the end of the inclined arm 21 away from the vertical arm 23 is fixedly connected to the second horizontal arm 222. The end of the second horizontal arm 222 away from the inclined arm 21 is cantilevered. Specifically, the first horizontal arm 221 and the second horizontal arm 222 can be arranged parallel to each other, the vertical arm 23 can be perpendicular to the first horizontal arm 221 and the second horizontal arm 222, the vertical arm 23 is parallel to the longitudinal beam 1, and the angle between the extension line of the inclined arm 21 and the longitudinal beam 1 is an obtuse angle (i.e., ...). Figure 4 (∠β); Furthermore, the angle between the extension of the inclined arm 21 and the longitudinal beam 1 is 100°~130°.
[0081] Template connecting component 4 is disposed on the second horizontal arm 222;
[0082] One end of the first diagonal brace 3 is fixedly connected to the longitudinal beam 1, and the other end of the first diagonal brace 3 is fixedly connected to the inclined arm 21.
[0083] Furthermore, such as Figure 4As shown, the end of the first horizontal arm 221 furthest from the longitudinal beam 1 abuts against the first diagonal brace 3. This contact between the first horizontal arm 221 and the first diagonal brace 3 provides an additional support point at the distal end of the first horizontal arm 221, allowing the load to be directly transferred from the first horizontal arm 221 to the first diagonal brace 3, and then from the first diagonal brace 3 to the longitudinal beam 1. This support significantly improves the bending and shear resistance of the first horizontal arm 221, especially when bearing external loads such as formwork and concrete, reducing deformation and thus ensuring the stability of the entire support structure.
[0084] The cantilevered formwork support provided in this embodiment can form a multi-layered support structure, effectively distributing the load of the formwork and concrete, avoiding excessive pressure on a single component, thereby enhancing the overall stability of the support. Specifically, the obtuse angle design between the inclined arm 21 and the longitudinal beam 1 allows the second horizontal arm 222 and the inclined arm 21 to transfer part of the vertical force to the first horizontal arm 221 through an inclined path when bearing loads (such as the weight of the formwork and concrete). The first horizontal arm 221 and the inclined arm 21 are connected by a vertical arm 23, which provides vertical support. One end of the first horizontal arm 221 is fixedly connected to the longitudinal beam 1, and the other end is connected to the vertical arm 23, serving as the horizontal foundation of the entire cantilever 2 structure. It not only supports the vertical arm 23 and the second horizontal arm 222, but also transfers the load of the formwork and concrete to the longitudinal beam 1, ultimately distributing it to the outer facade of the wharf, ensuring the overall stability of the support.
[0085] The first diagonal brace 3 is fixed at one end to the longitudinal beam 1 and at the other end directly to the inclined arm 21, forming a stable triangular support structure together with the longitudinal beam 1 and the inclined arm 21. This triangular design significantly improves the overturning resistance of the support, especially when subjected to wind loads or construction loads, effectively reducing structural deformation and vibration. This multi-layered support and optimized mechanical design provide higher safety assurance for construction personnel and reduce accidents that may result from support failure.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
