Description

Technical Field

[0001] This invention relates to the forming technology of light steel support structure in the field of engineering construction, specifically a non-destructive near-water load-bearing platform. Background Technology

[0002] With social development and the improvement of people's living standards, people have increasingly higher demands for outdoor activities after their busy work schedules. In addition to traveling, they also enjoy outdoor activities such as walking and playing in parks and waterfront areas. Considering the above needs, load-bearing platforms are often built in waterfront areas for municipal engineering and homestay construction to facilitate the subsequent laying of landscape paths, landscape platforms, and the construction of the main structure of homestays.

[0003] In existing technologies, there are two main methods for constructing load-bearing platforms at the edge of water bodies: cement masonry and scaffolding.

[0004] While cement masonry has advantages such as good structural stability, good load-bearing capacity, long service life, and easy maintenance, it also has disadvantages such as long construction period, high cost, and the need to destroy the original structure (including soil structure and vegetation structure) at the edge of the water body during construction.

[0005] The support structure of a load-bearing platform under the scaffolding construction method mainly consists of supporting columns, load-bearing beams, and a platform. It primarily utilizes steel or log structures as the main body and is assembled on-site. This method allows for non-destructive construction of the load-bearing platform, and the assembled platform blends well with the surrounding environment, contributing to an ecological environment. However, the drawbacks lie in the fact that existing load-bearing platform support structures are often relatively simple. Supporting columns, load-bearing beams, and the platform are mostly connected directly via welding or threaded connectors. This results in poor on-site assembly convenience, high operational difficulty, and the quality of the connectors or welds directly affects the connection quality and structural strength. Variations in worker skill levels lead to poor stability, often failing to achieve the desired results. These shortcomings are amplified when constructing supports near water, causing structural defects to easily occur in similar load-bearing platform structures during actual use. After a certain period of use, local displacement, breakage, and collapse are likely to occur, requiring regular maintenance to ensure performance. Summary of the Invention

[0006] The technical problem solved by this invention is to provide a non-destructive near-water load-bearing platform that is easy to assemble and disassemble, easy to build and form, and can ensure the overall steel structure load-bearing beam of the platform can withstand pressure and seismic performance after connection and fixation, and maintain the strength of the interface position and the stability of the connection, so as to solve the defects in the above-mentioned technical background.

[0007] The technical problem solved by this invention is achieved by the following technical solution:

[0008] A non-destructive near-water load-bearing platform includes a platform body and legs;

[0009] The platform body is a rectangular platform with its length direction extending into the water body and its width direction perpendicular to the length direction. The platform body is a modular platform, including a pre-formed upper frame and a lower frame. The upper frame has the same width dimension as the lower frame, and the upper frame has a larger length dimension than the lower frame.

[0010] The upper plate frame is set on the plane of the lower plate frame. One side of the upper plate frame is flush with the end face of the lower plate frame in the length direction, and the other side extends outward from the lower plate frame. The platform body sets the extended part of the upper plate frame on the water surface area of ​​the water body to form a cantilevered platform with no bottom support.

[0011] The lower plate frame includes longitudinal beams arranged along its width direction. Multiple longitudinal beams are evenly spaced along the length direction of the lower plate frame. The two outermost longitudinal beams are formed on the outer edge of the lower plate frame. Several horizontal beams are arranged parallel to each other between adjacent longitudinal beams. The upper plate frame and the lower plate frame are assembled and connected by a grid truss. The grid truss connection support points are located on the horizontal beams. The lower plate frame supports the cantilever platform on the longitudinal beams corresponding to the extended outer edge of the upper plate frame through a combination of corbels and diagonal braces. The corbels and diagonal braces are spaced apart along the width direction of the lower plate frame, and the two outermost support units are diagonal braces.

[0012] The lower surface of the lower plate frame is formed with an array of lining plates, and the lower surface of the lining plates is formed with a support foot fixing structure; the support foot, which serves as the supporting structure, is a steel pipe pile, the lower part of which is directly driven into the ground structure by a pile driver, while the upper part is cut to a fixed length and assembled with the support foot fixing structure.

[0013] As a further limitation, the upper plate frame includes a frame support, the frame support has an outer frame formed by welding square steel, and through keels are arranged at intervals inside the outer frame. A slat frame is formed between adjacent through keels, and the slat frame is assembled below the plane of the through keel, and the surface of the slat frame serves as the panel assembly space.

[0016] As a further limitation, the upper frame is a modular assembly structure.

[0017] As a further limitation, the ratio of the dimensions of the lower plate frame in the length direction to the dimensions in the width direction is 3:4 to 3:2, and the difference between the upper plate frame and the lower plate frame in the length direction is 1 / 6 to 1 / 5 of the dimension of the lower plate frame in the length direction.

[0018] As a further definition, the longitudinal beam is an I-beam, and the transverse beam is a rectangular cross-section tube;

[0019] The lower plate frame is provided with U-shaped fasteners at intervals on the longitudinal beams corresponding to the side of the cantilever platform. The U-shaped fasteners are fastened to the surface of the longitudinal beams from the side of the cantilever platform, and the lower part of the diagonal brace is abutted against and assembled on the U-shaped fasteners.

[0020] The liner is preferably formed by welding onto the lower surface of the flange of the longitudinal beam.

[0021] As a further limitation, the corbel structure is an I-shaped or T-shaped steel component, formed by welding between the upper and lower plates.

[0022] As a further limitation, when the brackets are arranged in the width direction, the number of brackets is two, symmetrically arranged at the 1 / 3 and 2 / 3 positions of the length of the longitudinal beam.

[0023] As a further limitation, the support fixing structure is an assembly pipe, the assembly pipe includes a base plate, the assembly pipe is welded to the liner plate as a whole through the base plate, a steel round pipe body is formed on the surface of the base plate, and a rubber gasket is installed between the bottom of the steel round pipe body and the base plate, the steel round pipe body is used to fill the end face assembly of the steel pipe pile as the support through the filling assembly structure.

[0024] In the filling assembly structure, the steel round pipe body is concentrically fitted onto the outside of the steel pipe pile, and the steel pipe pile is fitted with three rubber bushings on the outer pipe surface at the fitting position. The outer diameter of the rubber bushings is smaller than the inner diameter of the steel round pipe body, and cement masonry is formed by pressure grouting in the gap space between the inner side of the steel round pipe body, the steel pipe pile, and the rubber bushings.

[0025] Beneficial effects: The non-destructive water-adjacent load-bearing platform of this invention can be used to build a water-friendly load-bearing platform structure in water-adjacent areas.

[0030] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. The described embodiments are merely some, not all, of the embodiments of this invention.

[0031] It should be noted that, in the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, "multiple" means two or more, and the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0032] See Figures 1-3 A preferred embodiment of a non-destructive near-water load-bearing platform is described below. In this embodiment, the load-bearing platform is located near the water in a wetland park and is used as a platform for building an integrated prefabricated homestay. The corresponding integrated prefabricated homestay is a single-story light steel structure building prefabricated in a factory.

[0033] The load-bearing platform includes the main body of the platform, which serves as the platform for building the homestay, and the legs set under the main body of the platform as a supporting structure.

[0034] In this embodiment, the platform body includes an upper frame 1 and a lower frame 6, both of which are rectangular structures. To facilitate transportation and structural assembly, both the upper frame 1 and the lower frame 6 are modular prefabricated structures. During on-site assembly, the upper frame 1 and the lower frame 6 are pre-assembled separately, and then combined with other structural components after the prefabrication is completed.

[0035] The upper frame 1 can be implemented in various ways in different embodiments, and its typical structural forms are two:

[0036] In Embodiment 1, the upper frame 1 includes a frame support, which comprises several structural components that can be welded on-site. It includes a rectangular outer frame formed by welding square steel. Through-beams are spaced along the inner side of the outer frame's outline. A slatted frame is formed within the hollowed-out frame space between adjacent through-beams. The slatted frame is assembled in the hollowed-out frame space using existing methods such as welding or threaded connections. The lower surface of the slatted frame is flush with the lower surface of the rectangular outer frame, while its upper surface is below the upper surface of the rectangular outer frame, facilitating the installation of a panel flush with the upper surface of the rectangular outer frame on the slatted frame surface. The panel material can be one or a combination of wood panels, wood-plastic composite panels, steel structure panels, and metal alloy panels. This embodiment is the optimal technical solution with the widest applicability.

[0037] In Embodiment 2, the corresponding upper frame 1 is a steel-framed lightweight precast sandwich panel, and its forming method is similar to that of an aluminum formwork precast panel structure. First, aluminum molds are spliced ​​to obtain a mold body of the corresponding size. Then, steel bars are pre-embedded in the mold body, and the inner surface of the mold body is lined with fiberglass mesh. Then, lightweight cement of the same type as foamed cement is poured into the mold body to form the corresponding steel-framed lightweight precast sandwich panel. The corresponding steel-framed lightweight precast sandwich panel also has a steel structure support embedded in the lower surface as an assembly part. The technical solution of this embodiment is an optional technical solution. Its advantage over the above technical solutions is that the aluminum mold body can be formed first, and the aluminum mold body can be assembled with the lower frame, and then the casting and demolding can be performed.

[0038] In this embodiment, the lower frame 6 includes multiple longitudinal beams 3. These longitudinal beams 3 are of equal length and arranged in parallel. The longitudinal beams 3 are cut to a fixed length from I-beams. Adjacent longitudinal beams 3 are spaced together by end-face welding at the corresponding web 22 positions of the I-beams to form multiple transverse beams 23. The transverse beams 23 are all rectangular cross-section steel pipes, and the long side of the transverse beam 23 is equal to the height of the web 22 of the longitudinal beam. These transverse beams 23 are arranged in parallel and at equal intervals between the webs 22 of the longitudinal beams. The resulting structure is as follows: Figure 3 As shown. The lower frame 6 is located outside the outermost longitudinal beam 3 on one side, as shown. Figure 2 The pattern shown is covered with multiple U-shaped fasteners 11, which are fastened to the outer side of the longitudinal beam 3 on the open side and fixed by welding.

[0039] The formed upper plate frame 1 and lower plate frame 6 can be used to assemble the main body of the platform. The upper plate frame 1 and lower plate frame 6 formed in pairs and used to assemble a set of main body of the platform should have the following dimensional characteristics: the upper plate frame 1 has the same width as the lower plate frame 6, the length of the upper plate frame 1 is greater than the length of the lower plate frame 6, and the length difference is 1 / 6 to 1 / 5 of the length of the corresponding lower plate frame 6.

[0040] The main structure of the platform after it is completed is as follows: Figure 1 As shown, the upper plate frame 1 and the lower plate frame 6 are connected by a grid truss 2. The grid truss 2 serves as a force buffer structure, a force balance structure, and a stabilizing structure. Its upper part is integrally formed with the upper plate frame 1, while its lower part is connected to the lower plate frame 6 at the crossbeam 23.

[0041] When the upper frame 1 and lower frame 6 are assembled into the platform body, the direction extending towards the water body 14 is taken as the length direction of the platform body, and the direction perpendicular to the length direction is taken as the width direction of the platform body. In this embodiment, the length direction of the platform body corresponds to the length direction of the upper frame 1 and the lower frame 6, and the length direction of the platform body corresponds to the width direction of the upper frame 1 and the lower frame 6. The upper frame 1 and the lower frame 6 are stacked flush in the width direction, while in the length direction, the upper frame 1 is flush with the lower frame 6 on one side (opposite to the lower frame 6). Figure 1 The left side of the state is described, while the other side extends outward from the end face of the lower plate frame 6.

[0042] The lower frame 6 supports the extended portion of the upper frame 1 on the crossbeam 23 corresponding to the extended outer edge of the upper frame 1 through a structural combination of brackets 8 and diagonal braces 9.

[0043] The diagonal brace 9 rests against and is formed on the U-shaped fastener 11 correspondingly provided on the longitudinal beam 3 at the connecting end of the lower plate frame 6. The connecting end on the upper plate frame 1 is formed on the outer edge of the bottom surface of the upper plate frame 1 as an outer support 10 of the diagonal brace. The corresponding outer support 10 of the diagonal brace is formed on the bottom surface of the upper plate frame 1 by welding. The number of diagonal braces 9 is the same as the number of U-shaped fasteners 11. Different outer supports 10 of the diagonal brace support support the upper plate frame 1 with different inclinations. That is, the setting position on the lower surface of the upper plate frame 1 can be located on the same straight line parallel to the width direction of the platform body, or it can be set on multiple different straight lines parallel to the width direction of the platform body according to the result of stress optimization.

[0044] In this embodiment, the corbel 8 and the upright beam 7 are combined and arranged together. The upright beam 7 is an I-beam, which directly abuts against the surfaces of the upper plate frame 1 and the lower plate frame 6 on its upper and lower end faces and is integrally formed with them. The corbel 8 is a steel component with an I-shaped cross-section. The inner surface of the corbel 8 is as follows: Figure 1 The bracket shown rests against the surface of the upright beam 7 and is connected to the upright beam 7 as a whole through multi-point welding; the lower part of the bracket 8 is welded to the upper surface of the longitudinal beam flange 21 of the corresponding longitudinal beam 3, while the top surface rests against and is fixed to the lower surface of the upper plate frame 1 by welding. Two brackets 8 are provided, symmetrically arranged at 1 / 3 and 2 / 3 of the length of the longitudinal beam, and at least one diagonal brace 9 should be reserved on the outer side of the two brackets 8.

[0045] In different embodiments, the corbel 8 can also be set alone without the need for the upright beam 7, but the load-bearing performance and stability after load-bearing are slightly worse; in addition, the corbel 8 can also be a T-shaped steel component.

[0046] In this embodiment, the lower plate frame 6 has arrayed lining plates 15 welded onto its lower surface, and each lining plate 15 has a corresponding mounting pipe 4. The mounting pipe 4 is used to connect and assemble the steel pipe piles 13, which serve as the supporting structure. In order to ensure the supporting strength of the mounting pipe 4, the corresponding lining plates 15 should be located on the lower surface of the longitudinal beam flange 21 as much as possible.

[0047] Figure 2 The detailed drawing shows the cross-sectional structure of the assembly pipe 4, which consists of a base plate 16 and a steel round pipe body 17. The base plate 16 is a connecting assembly used to form an integral part with the liner plate 15 by welding. The steel round pipe body 17 is formed on the lower surface of the base plate 16, and multiple triangular reinforcing ribs 5 are welded to the outer circumference of the steel round pipe body 17 to ensure the structural stability of the steel round pipe body 17. The steel round pipe body 17 has an inner diameter larger than the outer diameter of the steel pipe pile 13, and a rubber gasket 19 of the same size is lined on the inner bottom surface of the steel round pipe body 17.

[0048] In this embodiment, when assembling the water-side load-bearing platform, the upper frame 1 and the lower frame 6 are first assembled. Then, the assembly position is selected at the construction site in the water-side area. After the assembly position is selected, a pile driver is used to drive multiple steel pipe piles 13, which serve as the support structure, into the selected position in the water-side ground area 12. Then, a liner plate 15 is welded onto the lower surface of the lower frame 6 according to the driving position of the steel pipe piles 13, and a matching pipe 4 is formed and installed on the liner plate 15.

[0049] The steel pipe piles 13 are processed using a fixed-length cutting process to ensure that the top surfaces of all steel pipe piles 13 are on the same assembly plane. Three rubber bushings 20 are fitted on the top of the steel pipe piles 13. Then, the lower plate frame 6 is hoisted so that the mounting pipes 4 are fitted onto the steel pipe piles 13. The lower end face of the mounting pipes 4 is sealed, and then pressure grouting is performed to fill the gap between the steel pipe piles 13, the mounting pipes 4 and the steel round pipe body 17 with high-strength cement. After the high-strength cement is formed, the cement masonry 18 is obtained. At this time, the assembly of the steel pipe piles 13 and the lower plate frame 6 is completed.

[0050] After the steel pipe pile 13 and the lower plate frame 6 are assembled, the lower ends of the grid truss 2, diagonal brace 9, vertical beam 7 and corbel 8 are assembled on the lower plate frame 6. Then, the upper plate frame 1 is hoisted and positioned on the lower plate frame 6. When the upper plate frame 1 is hoisted and positioned, the left end face of the upper plate frame 1 is made to be flush with the lower plate frame 6, and the right end face of the upper plate frame 1 extends beyond the lower plate frame 6 and extends into the water surface area of ​​the water body 14 to form a cantilevered platform without bottom support as a water-friendly platform.

[0051] In terms of structure, the upper frame 1 and lower frame 6 of the water-facing load-bearing platform in this embodiment can be customized according to actual dimensions. All components can be factory-produced, ensuring compatibility and facilitating batch processing and structural component replacement. On-site assembly construction can save more than 80% of the construction time compared to traditional buildings. The structural combination of the grid truss 2 and corbel 8 between the upper frame 1 and lower frame 6 makes the main structure of the entire load-bearing system more stable, simpler, and lighter than traditional masonry platform structures. It ensures uniform stress distribution, robustness, reliability, and excellent strength. The combination of the diagonal brace 9 on the rightmost longitudinal beam 3 with the vertical beam 7 and corbel 8 creates a triangular load-bearing shape on the outer edge of the water-facing platform of the upper frame 1. This improves the load-bearing capacity of the water-facing platform in a cantilevered state without supporting columns at the bottom. Simultaneously, the connection has good stability, and there is no concern about corrosion of structural components after immersion in water.

[0052] The connection and assembly structure between the lower plate frame 6 and the steel pipe pile 13 of the near-water load-bearing platform in this embodiment, which is connected by the mounting pipe 4, has good structural stability and assemblability. It can effectively optimize the stress on the platform, reduce the impact of the loose and soft soil of the near-water ground 12 on the stability of the platform, and has a certain self-adjustment capability. It can effectively improve the seismic resistance and anti-slip performance of the platform after connection and molding, so that the load-bearing platform can maintain structural stability for a long time after molding.

[0053] As for the technical solution itself, the water-bearing platform in this embodiment does not require destructive construction of the vegetation and soil structure in the platform setting area during platform forming construction. Only a few steel pipe piles 13 need to be driven in as support structures. The main body of the formed platform is a cantilever structure, which will not affect the normal growth of the vegetation below and can effectively improve the degree of integration with the environment. When building homestays on its surface, it can better present the regional cultural characteristics. Combined with the water-friendly platform of the extended part of the frame 1, it can make homestays closer to nature. In an era that pays more attention to ecological protection, natural landscape, original ecology and low-carbon economy, it is more in line with market demand and taste, and is a new type of green and environmentally friendly tourist accommodation.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
