Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for underwater enclosure of cantilever scaffolding. Background Technology

[0002] Currently, cantilever scaffolding is widely and maturely used. Seabed enclosure is crucial for both safety and aesthetics. Conventional seabed protection for cantilever scaffolding involves fully covering the cantilevered steel sections with wooden formwork. Projects prioritizing safety, aesthetics, and a more civilized appearance may add an additional layer of seabed bottom enclosure. However, this typically involves simply using wooden planks and timber framing for the ceiling, then painting it red and white. Furthermore, the aesthetics and stability of the wooden framing ceiling are relatively poor. Overall, conventional seabed enclosure construction is relatively simple, primarily meeting safety requirements. However, projects with higher safety and aesthetic standards, or those needing to showcase local characteristics, require further improvement. Summary of the Invention

[0003] In view of this, the present invention provides a method for underwater enclosure using cantilever scaffolding, which improves the robustness and aesthetics of conventional underwater enclosure structures, creates underwater enclosures suitable for high standards and diverse themes in different regions, and improves the efficiency of underwater enclosure implementation.

[0004] The present invention provides a method for underwater closure of cantilever scaffolding, which adopts the following technical solution:

[0005] A method for underwater closure of cantilevered scaffolding includes a cantilevered frame body, wherein the cantilevered frame body includes a cantilevered support frame and a cantilevered main beam, the cantilevered main beam is horizontally disposed at the end of the cantilevered layer, and the cantilevered support frame is vertically fixed to the cantilevered main beam, comprising the following steps:

[0006] S1. Cantilever scaffolding erection: Install the cantilever main beam and cantilever frame according to the plan and design requirements. The upper end of the cantilever main beam is enclosed at the seabed to form a safe installation condition.

[0007] S2. Scheme Design and Layout: Based on the characteristics of the building, design the layout of the underwater enclosed ceiling to lay the groundwork for material processing and installation;

[0008] S3. Fabrication of cantilever main beam keel: Fabricate the keel of each section of the cantilever main beam according to the plan. The keel fabrication can be carried out on the ground. Weld and pre-assemble the keel of each section according to the drawings.

[0009] S4. Keel Installation: The keel, which has been processed on the ground, is hoisted to the seabed position using a tower crane. The keel is fixed to the cantilever main beam by intermittent spot welding.

[0010] S5. Aluminum Composite Panel Manufacturing, Processing and Installation: Arrange and print aluminum composite panels according to the pre-selected theme, and fix them to the keel with self-tapping screws. The joints of the aluminum composite panel panels must be tightly and firmly bonded.

[0011] S6. Production of exterior decorative advertisements: Prepare the advertisement text to be installed in advance according to the design plan, and stick and fix it on the surface of the aluminum composite panel.

[0012] Furthermore, the cantilever frame can be driven to slide on the cantilever main beam to adjust the distance between the cantilever frame and the wall.

[0013] Furthermore, the cantilever main beam is provided with multiple grooves for the sliding of the cantilever frame, and the bottom of the cantilever frame is provided with multiple parallel sliders. The sliders can be limited in the grooves and slide in the grooves. The sliders pass through the aluminum composite panel.

[0014] Furthermore, the groove extends through the cantilevered main beam, and the slider can slide out of the groove from the end of the cantilevered main beam.

[0015] Furthermore, the cantilever layer is provided with a driving component for moving the cantilever frame on the cantilever beam. The driving component is a jack, and the output end of the driving component is connected to the cantilever frame.

[0016] Furthermore, the cantilever main beam is provided with a diagonal bracing assembly, which is located near the end of the cantilever main beam and is fixed to the upper cantilever layer.

[0017] Furthermore, the inclined cable assembly includes two inclined cable rods and an adjusting tube disposed between the two inclined cable rods. The lower inclined cable rod is hinged to the cantilever main beam, and the upper inclined cable rod is fixedly connected to the upper cantilever layer. The two ends of the adjusting tube are threaded onto the two inclined cable rods, and the external threads on the two inclined cable rods are in opposite directions.

[0018] In summary, this invention offers at least one of the following advantages: the keel, made of lightweight rectangular tubing and other materials, can be spot-welded to the cantilevered main beam, resulting in high stability; the aluminum composite panel, being a pre-fabricated profile, boasts superior straightness and aesthetics, and can be connected to the keel as a robust whole using screws, thus avoiding the drawbacks of traditional wooden keels having limited load-bearing capacity; furthermore, the aluminum composite panel has a higher degree of flatness and rigidity than conventional wood panels, and its UV printing inherently provides decorative effects, allowing for better design and integration of advertising fonts and theme backgrounds. The entire assembly can be prefabricated on the ground before high-altitude installation, resulting in a high degree of modularity and efficiency. Attached Figure Description

[0023] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0025] This invention discloses a method for underwater closure of cantilevered scaffolding. (Refer to...) Figure 1 and Figure 2 A method for enclosing a cantilevered scaffold underwater, comprising a cantilevered frame 1, the cantilevered frame 1 including a cantilevered frame 11 and a cantilevered main beam 12, the cantilevered main beam 12 being horizontally positioned at the end of the cantilevered layer, and the cantilevered frame 11 being vertically fixed to the cantilevered main beam 12, comprising the following steps:

[0026] Step 1: Erection of cantilever frame 1: Install the cantilever main beam 12 and cantilever frame 11 according to the plan and design requirements. The upper end of the cantilever main beam 12 is sealed off from the seabed, forming a safe installation condition.

[0027] Step 2, Scheme Design and Layout: Based on the characteristics of the building, the layout of the underwater enclosed ceiling is designed, and floor plans are drawn using BIM or CAD to lay the groundwork for material processing and installation;

[0028] Step 3: Fabrication of the 12 keels of the cantilever main beam: Fabricate the 12 keels of the cantilever main beam for each section according to the plan. The keel fabrication can be carried out on the ground. Weld and pre-assemble the keels of each section according to the drawings.

[0029] Step 4, Keel Installation: The keel, which has been processed on the ground, is hoisted to the seabed position using lifting tools such as tower cranes. At this time, the ground-supported scaffolding under the seabed has not yet been dismantled and can be used as an installation platform. The keel is fixed to the cantilevered steel main beam by intermittent spot welding. During the installation process, it is necessary to focus on controlling the flatness, dimensional positioning and spot welding quality.

[0030] Step 5: Aluminum Composite Panel Fabrication, Processing, and Installation: Arrange and print the aluminum composite panels according to the pre-selected theme. Background patterns and other elements can be printed together. The size should meet the on-site installation dimensions. Hoist the aluminum composite panels onto the installation platform and fix them to the keel with self-tapping screws. The screw spacing should not be too sparse. The joints and other parts of the aluminum composite panel panels must be tightly and firmly bonded.

[0031] Step Six: Production of Exterior Decoration Advertisements: Prepare the text or theme of the advertisement to be installed in advance according to the design plan, and paste and fix it on the surface of the aluminum composite panel. The text should be beautiful and neat, and the layout should be well thought out.

[0032] To facilitate the installation and disassembly of the cantilever frame 11, the cantilever frame 11 can be driven to slide on the cantilever main beam 12 to adjust the distance between the cantilever frame 11 and the wall. The cantilever main beam 12 is provided with multiple grooves 121 for the cantilever frame 11 to slide. The bottom of the cantilever frame 11 is provided with multiple parallel sliders 111. In this embodiment, the groove 121 is a T-shaped groove, and the slider 111 is a T-shaped block. The slider 111 can be confined within the groove 121 and slide within it. The slider 111 passes through the aluminum composite panel, and the groove 121 passes through the cantilever main beam 12. The slider 111 can slide from the end of the cantilever main beam 12. When installing the cantilever frame 11, the assembled cantilever frame 11 is transported to the end of the cantilever main beam 12, so that the slider 111 at the bottom of the cantilever frame 11 is aligned with the slide groove on the cantilever main beam 12. The slider 111 is pushed into the slide groove 121, so that the cantilever frame 11 moves on the cantilever main beam 12. After the cantilever frame 11 is moved to a suitable position, it is fixed. Similarly, when disassembling the cantilever frame 11, the cantilever frame 11 is loosened and pushed outwards from the cantilever main beam 12. The cantilever frame 11 is then lifted away using transport equipment. This also facilitates the adjustment of the distance between the cantilever frame 11 and the construction wall, making it convenient for construction personnel to carry out the work.

[0033] To facilitate the movement and fixation of the cantilever frame 11, a drive unit 3 is provided on the cantilever layer for moving the cantilever frame 11 on the cantilever beam 12. In this embodiment, the drive unit 3 is a jack. The number of drive units 3 is determined according to the size of the cantilever frame 11. The output end of the drive unit 3 is connected to the cantilever frame 11. After the cantilever frame 11 is installed on the cantilever main beam 12, the output end of the jack is fixed to the cantilever frame 11. The jack can push and pull the cantilever frame 11 to move on the cantilever main beam 12, making it more convenient to use.

[0034] Since the cantilever main beam 12 is completely suspended in the air, it needs to withstand a large amount of gravity. In order to enable the cantilever main beam 12 to withstand greater gravity, multiple sets of diagonal bracing assemblies 2 are provided on the cantilever main beam 12. The diagonal bracing assemblies 2 are located near the ends of the cantilever main beam 12 and are fixed to the upper cantilever layer. The diagonal bracing assemblies 2 include two diagonal bracing rods 21 and an adjusting tube 22 disposed between the two diagonal bracing rods 21. The lower diagonal bracing rod 21 is hinged to the cantilever main beam 12, and the upper diagonal bracing rod 21 is fixedly connected to the upper cantilever layer. The two ends of the adjusting tube 22 are threaded onto the two diagonal bracing rods 21. The external threads on the two diagonal bracing rods 21 are in opposite directions. By rotating the adjusting tube 22, the two bracing rods 21 can be brought into a taut state, applying tension to the cantilever main beam 12, so that the cantilever main beam 12 can withstand greater gravity and is safer to use.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
