Description

Technical Field

[0001] The utility model relates to the technical field of floating platforms, and particularly relates to a lightweight cement-based material cage structure floating platform. Background Art

[0002] Due to the limitations of material properties, current cement-based material floating platforms often require relatively thick structures to ensure their bearing capacity. This not only leads to an excessive self-weight of the structure, increasing the difficulty of transportation and installation, but also significantly increases the material consumption and cost.

[0003] The heavy structure also poses higher requirements for the connection between components, increasing the complexity and difficulty of construction. At the same time, due to the excessive self-weight of the structure, the actual bearing capacity of the floating structure is relatively low, restricting its application in some scenarios with high load requirements.

[0004] In addition, due to the relatively large weight of each part of the traditional cement concrete floating platform, the center of gravity of the structure is relatively high. To reduce the center of gravity and improve stability, more ballast blocks are required. When the center of gravity of the floating structure is relatively high, it is prone to shaking and tilting under the influence of external factors such as water flow, wind and waves, posing great safety hazards to its use.

[0005] Due to the insufficient understanding of high-strength and high-toughness cement-based materials (such as UHPC) by designers, and the lack of sound design specifications for building structures and floating structures of such new materials, when designing high-strength and high-toughness structures, the design specifications of ordinary building structures or road and bridge structures are still referred to. Often, for the sake of safety, designers will adopt a large structural redundancy according to the design method of ordinary building structures. For example, when designing steel-concrete structure components, a thickness of 10 - 20 mm or even more needs to be reserved for the steel bar protection layer only. Therefore, the thickness and other dimensions of many high-strength and high-toughness cement-based material structures are relatively large. As a result, the cement material floating structures designed according to this idea have a large self-weight, poor bearing capacity, and it is difficult to reduce the center of gravity of the structure.

[0006] With the rapid development of aquaculture, water-based leisure and entertainment, water-based photovoltaic and other aspects, the demand for low-cost and large-capacity floating platforms is increasing continuously. Considering various requirements such as firmness, environmental protection, durability and functionality, it is currently considered that the development of lightweight cement-based material floating platforms is a new type of equipment that meets the needs of offshore comprehensive development and rural revitalization. Therefore, the utility model proposes a lightweight cement-based material cage structure floating platform. Content of the Utility Model

[0007] The purpose of the utility model is to propose a lightweight cement-based material cage structure floating platform for the deficiencies in the above technologies, aiming to solve the existing problems.

[0009] A cage-shaped frame, on which there are multiple installation spaces;

[0010] Float boxes, fixedly installed in the installation spaces, and internally partitioned into multiple cavities by partition plates;

[0011] Strip plates, fixedly installed on the cage-shaped frame;

[0012] A counterweight device, the cage-shaped frame includes a top frame, a bottom frame and columns, and the bottom frame is connected to the top frame through the columns; the counterweight device is suspended at the joints of the four sides of the bottom frame and the columns.

[0013] Preferably, the counterweight device includes a suspension rod, a round block and multiple round plates. The suspension rod is fixed on the round block, and multiple round plates are fixedly stacked on the suspension rod from top to bottom; the suspension rod is suspended at the bottom of the cage-shaped frame through a cable. The cable is suspended at the intersection of the longitudinal beam and the cross beam at the bottom of the cage-shaped frame; the length of the cable is less than the distance between adjacent two counterweight devices.

[0014] Preferably, the cage-shaped frame and the float boxes are made of UHPC material. It also includes rubber pads, which are arranged on the float boxes and are located at the contact positions between the float boxes and the cage-shaped frame.

[0032] In order to more easily understand the structure of the present utility model and the functional features and advantages that can be achieved, the following will describe the preferred embodiments of the present utility model in detail in conjunction with the drawings as follows:

[0033] Embodiment:

[0034] As Figures 1 to 6 shown, the present utility model provides a lightweight cement-based material box cage structure floating platform, including:

[0035] A cage-shaped frame 1, on which there are provided a plurality of installation spaces;

[0036] A floating box 2, fixedly installed in the installation space, and internally divided into a plurality of cavities by a partition board 21;

[0037] A strip board 3, fixedly installed on the cage-shaped frame 1; the thickness of the strip board 3 is generally 20 - 30 mm, the width is 80 - 100 mm, and the laying gap is 40 - 60 mm;

[0038] A counterweight device 4.

[0039] The cage-shaped frame 1 and the floating box 2 of the present utility model are made of UHPC material, that is, high-strength and high-toughness cement-based material, and the cage-shaped frame 1 is made of UHPC strips 3 with a single square cross-sectional size. The wall thickness of the cement-based material floating box 2 as a floating body is only 20-40 mm thick, which is one-fifth of the wall thickness of the ordinary concrete structure.

[0040] See Figure 3 , the cage-shaped frame 1 of the present utility model includes a top frame 11, a bottom frame 12 and columns 13, and the bottom frame 12 is connected to the top frame 11 through the columns 13. The columns 13 between the top frame 11 and the bottom frame 12 can be welded and connected through embedded steel plates or steel bars, and then sealed with sealant and fiber composite. At the contact between the floating box 2 and the top frame 11 and the bottom frame 12, it is bonded with polymer mortar or waterproof structural adhesive. If there are obvious gaps, it is filled with soft and tough materials such as rubber and foamed rubber. At the contact between the two sides of the floating box 2 and the cage-shaped frame 1, it is isolated or filled with soft materials. The counterweight device 4 is suspended at the connection between the four sides of the bottom frame 12 and the columns 13. The number of counterweight devices 4 suspended on the four sides of the bottom frame 12 is the same in the width direction, that is, the same number of counterweight devices 4 are suspended on the left and right sides of the bottom of the bottom frame 12 in the width direction; similarly, the number of counterweight devices 4 suspended on the four sides of the bottom frame 12 is also the same in the length direction, that is, the same number of counterweight devices 4 are suspended on the upper and lower sides of the bottom of the bottom frame 12 in the length direction. As Figure 5 shown, when three counterweight devices 4 are suspended on the left side of the bottom of the bottom frame 12, three counterweight devices 4 are also horizontally suspended on the right side in the same way; similarly, when two counterweight devices 4 are suspended on the upper side of the bottom of the bottom frame 12, two counterweight devices 4 are also horizontally suspended on the lower side in the same way.

[0041] Furthermore, in order to improve the integrity of the structure and the efficiency of the manufacturing process, the top frame 11 and the bottom bottom frame 12 can be integrally prefabricated, and the assembly process is transformed into the problems of placing the floating box 2 and connecting the top frame 11 and the bottom frame 12, which can greatly simplify the assembly process.

[0042] See Figure 4 , the counterweight device 4 of the present utility model includes a suspension rod 41, a round block 42 and multiple round plates 43. The suspension rod 41 is fixed on the round block 42, and multiple round plates 43 are stacked and fixed on the suspension rod 41 from top to bottom; the suspension rod 41 is suspended at the bottom of the cage-shaped frame 1 through a cable.

[0043] The cable is suspended at the intersection of the longitudinal beam and the cross beam at the bottom of the cage-shaped frame 1; the length of the cable is less than the distance between two adjacent counterweight devices 4 to prevent the two adjacent counterweight devices 4 from colliding with each other. The round block 42 of the laminated counterweight device 4 is a solid circular block; the round plates 43 are three pieces, and the three concentric round plates 43 with different sizes are stacked from bottom to top in the order from large to small. The three round plates 43 are kept at a certain interval in the vertical direction and fixed together.

[0044] The utility model further comprises a rubber pad, which is fixed on the buoyancy box 2 and located at the contact position between the buoyancy box 2 and the cage-shaped frame 1 .

[0045] As another embodiment of the present invention, Figure 3 As shown, the top frame 11 and the bottom frame 12 of the utility model include a plurality of square profiles, and 2-3 parallel steel bars are pre-set in the square profiles, which are used for structural reinforcement and connection between components. When making the profiles, the pre-set steel bars are exposed at the ends by about 20mm, which are used for installation and connection when connecting between components. The size range of the square profiles in the utility model is 80-100mm in width and 60-80mm in thickness, and the specific length can be determined according to the position of the profiles in the cage frame 1.

[0046] Specifically, the UHPC premix is ​​cast in a U-shaped groove mold to obtain a thin-walled, cavity-enclosed pontoon 2, which contains short-cut steel fibers, but the main structure has no steel bars. In order to obtain a closed space, a cover plate is prefabricated with the same material, matched with the U-shaped box, and a sealed pontoon 2 is formed by waterproof glue, etc. The wall thickness of the pontoon 2 is 20-40mm, and the thickness is appropriately increased in the parts that need to be connected and have greater stress. Only a small amount of steel bars are provided in the parts that need to be connected. The wall thickness of the pontoon 2 referred to in the utility model is generally 20mm, and the thickness of the square profiles at both ends is 40mm. Several sections of short steel bars are embedded in the upper and lower edges of the square profiles at both ends, and the ends are exposed for subsequent connection with the cage-shaped frame 1. Before sealing the pontoon 2, the internal space is filled with discarded empty plastic bottles of varying sizes (such as mineral water bottles). Plastic bottles are a safe reserve for the structure and can be easily taken out when they need to be recycled.

[0047] The two ends of the buoyancy box 2 of the utility model are preset with connecting steel bars, and the ends of the cage-shaped frame 1 are provided with connecting holes for connecting the steel bars.

[0048] Installation process of the floating platform of the utility model:

[0049] The box-cage floating structure of the utility model can be assembled from bottom to top. First, the length and quantity of the UHPC square profiles are determined according to the design drawings, and then the profiles are spliced ​​in the longitudinal and transverse directions. The steel bars are first welded and connected at the intersection of the profiles, and then the joints are sealed with a fiber cement mixture. This process is repeated to complete the assembly of the base frame 12 and the columns 13.

[0050] Next, place the prefabricated floating box 2 so that the rubber pads on the floating box 2 are in contact with the cage-shaped frame 1, and align the embedded steel bars at the front and rear ends of the floating box 2 with the reserved connection holes at the ends of the cage-shaped frame 1 one by one. Finally, install the top frame 11, that is, use the above-mentioned square profiles for splicing, welding, wrapping and sealing, etc. At the positions of the cage-shaped frame 1 corresponding to the two ends of the floating box 2, several holes are reserved respectively, which can be butted with the steel bar heads reserved up and down at the ends of the floating box 2.

[0051] See Figure 7 , among the multiple bottom frames 12 of the present utility model, they are connected by the staggered top frames 11 to connect the floating platforms composed of multiple cage-shaped frames 1 and floating boxes 2 together. Specifically, the floating platform can be infinitely expanded longitudinally or transversely, and the transverse or longitudinal profiles of the upper and lower layers span the floating platforms of two structural units, and realize firm upper and lower connections to form a cage network.

[0052] The present utility model uses high-strength and high-toughness cement-based materials to manufacture the frame of the floating structure and the floating box 2, and uses the formwork of UHPC material with a single square cross-section size to make the cage-shaped frame 1. The thin-walled floating box 2 is surrounded by the above-mentioned prefabricated cage-shaped frame 1, and the cage-shaped frame 1 is used to protect and strengthen the thin-walled floating box 2, significantly reducing the thickness of the structure and the overall weight of the structure.

[0053] There are 2-3 steel bars embedded at the center of the square profile, and the ends of the steel bars slightly protrude from the profile. On the one hand, the steel bars play a strengthening role, and at the same time, the ends of the steel bars are also the main ways for the components to be connected to each other. The profiles are connected by welding the embedded steel bars, which can greatly improve the integrity of the structure and effectively disperse and transfer the impact force on the structure from all directions.

[0054] In order to improve the stability of the floating platform, a counterweight device 4 composed of cement laminated plates is suspended around the lower part of the platform. The counterweight device 4 can lower the center of gravity of the structure and increase the resistance of the object moving in the water, thereby effectively improving the stability of the floating platform in the marine environment. Its principle is to increase the ability of the structure to resist swaying by lowering the center of gravity. And using the laminated plate counterweight device 4 is similar to the resistance when the paddle blade paddles in the water, so as to further reduce the swaying amplitude of the platform.

[0055] The above is only the preferred embodiment of the present utility model, and does not impose any form of limitation on the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the above technical content without departing from the scope of the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes. Therefore, all changes, modifications, equivalent changes and modifications made to the above embodiments according to the technical solution of the present utility model without departing from the content of the technical solution of the present utility model belong to the protection scope of this technical solution.
