Description

Technical Field

[0001] This utility model relates to the field of concrete floating bridge technology, and in particular to a prefabricated permeable concrete floating bridge. Background Technology

[0002] A pontoon bridge is a special type of bridge that does not rely on a fixed supporting structure but instead uses floating bodies to maintain its position on the water. In areas affected by tides, pontoon bridges are essential for maintaining a constant height to facilitate boarding and disembarking. Pontoon bridges can also serve as work areas in shipyards, ports, or docks.

[0003] Currently, the commonly used materials for floating bridges are concrete, metal, and plastic. The weight and size of concrete make floating bridges more difficult to move and maintain; metal floating bridges are prone to oxidation and deformation, requiring regular maintenance; and plastic floating bridges have lower stability and tensile strength. Metal and plastic materials can also have certain impacts on aquatic life and water quality. Furthermore, floating bridges made of these three materials pose certain safety hazards; they may leak after prolonged use, and during rain, water may accumulate on the surface, making the bridge slippery and affecting its usability.

[0004] Existing concrete floating bridges, such as the "Assembled High-Performance Reinforced Concrete Floating Bridge" with application number CN201810470984.8, have the following problems: it is difficult to form a circular platform for the application; although modular assembly is used, the modules are prone to misalignment, resulting in a lack of stability during use. Utility Model Content

[0005] This utility model provides a prefabricated permeable concrete floating bridge, which aims to solve the problems of existing concrete floating bridges, such as the difficulty in forming a circular platform for application, the ease with which modules can shift and the lack of stability during use, even though modular assembly is used.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A prefabricated permeable concrete floating bridge includes interconnected circular platforms and pedestrian walkways. The circular platforms are divided into several fan-shaped concrete floating plates. Each fan-shaped concrete floating plate has protrusions and grooves on both sides. Adjacent fan-shaped concrete floating plates are joined together by protrusions and grooves.

[0008] The pedestrian walkway includes several square concrete floating slabs arranged in a row. The front and rear sides of the square concrete floating slabs are respectively provided with protrusions and grooves, and adjacent square concrete floating slabs are mortised and tenoned together by the protrusions and grooves.

[0009] Several guardrails are detachably installed around the outer side of the circular platform and the top perimeter of the pedestrian walkway.

[0010] Preferably, the protrusions are all the same size, the grooves are all the same size, and the protrusions and grooves correspond one-to-one.

[0011] More preferably, all the protrusions are trapezoidal, the grooves are concentric and coaxial with the corresponding protrusions, the protrusions and the corresponding grooves are tenoned together to form a limiting fit, and there is a gap between the outer wall of the protrusion and the corresponding groove.

[0012] Furthermore, each of the aforementioned fan-shaped concrete floating plates is embedded with crisscrossing longitudinal and transverse steel wire ropes, and both ends of the longitudinal and transverse steel wire ropes pass through the side wall of the respective fan-shaped concrete floating plate and are provided with hooks.

[0013] Furthermore, the hooks on the sidewalls of adjacent fan-shaped concrete floating plates correspond one-to-one, and the corresponding hooks are interlocked with each other.

[0014] Specifically, the front end of the square concrete floating plate closest to the fan-shaped concrete floating plate is arc-shaped, and the arc-shaped end of the square concrete floating plate is tangent to the outer side of the fan-shaped concrete floating plate.

[0015] More specifically, each of the square concrete floating slabs is embedded with at least one longitudinal steel wire rope. The longitudinal steel wire ropes of adjacent square concrete floating slabs correspond one-to-one, and the corresponding longitudinal steel wire ropes are all located in a straight line. The two ends of the longitudinal steel wire rope pass through the side wall of the square concrete floating slab and are provided with hooks.

[0016] In detail, the hooks on the sidewalls of adjacent square concrete floating slabs correspond one-to-one, and the corresponding hooks are interlocked with each other.

[0017] Preferably, both the fan-shaped and square concrete floating slabs are made of permeable concrete with PP plastic balls as aggregate.

[0018] Preferably, each guardrail includes two vertical bars and two diagonal bars, with connectors at both ends of the vertical bars, and the two diagonal bars are cross-connected between the two vertical bars through the connectors.

[0019] The beneficial effects of this utility model are:

[0020] 1. A circular platform can be built using fan-shaped concrete floating slabs, which is convenient to use;

[0021] 2. The circular platform is decomposed into multiple fan-shaped concrete floating slabs, and the pedestrian walkway is decomposed into multiple square concrete floating slabs, which facilitates installation and disassembly. At the same time, the fan-shaped and square concrete floating slabs can be prepared in advance and installed on site, forming a prefabricated installation that can be assembled on site.

[0022] 3. The adjacent fan-shaped concrete floating plates and the adjacent square concrete floating plates can be connected by protrusions and grooves to form tenon joints, so that the adjacent modules form a limiting fit to prevent relative displacement and further ensure stability during use. At the same time, it is easy to install and connect. With the help of pre-embedded steel wire ropes and hooks, stability is greatly improved.

[0023] 4. Permeable concrete, using PP plastic balls as aggregate, is used as the floating bridge material. Compared with traditional concrete floating bridges, permeable concrete floating bridges are lighter, have good stability, and are easy to move. Compared with metal and plastic materials, permeable concrete floating bridges have less impact on aquatic organisms, water quality, and other environmental factors. They can better adapt to different weather conditions. On rainy days, the bridge surface can quickly drain accumulated water to ensure the safety of pedestrians. Attached Figure Description

[0031] The embodiments will be further described below with reference to the accompanying drawings.

[0032] like Figures 1-6 As shown in the preferred embodiment 1, a prefabricated permeable concrete floating bridge includes interconnected circular platforms and pedestrian walkways. The circular platforms are divided into several fan-shaped concrete floating plates 1. Each fan-shaped concrete floating plate 1 has a protrusion 2 and a groove 3 on both sides. Adjacent fan-shaped concrete floating plates 1 are mortised and tenoned together by the protrusion 2 and the groove 3.

[0033] The pedestrian walkway includes several square concrete floating slabs 7 arranged in a row. The front and rear sides of the square concrete floating slabs 7 are respectively provided with protrusions 2 and grooves 3. Adjacent square concrete floating slabs 7 are interlocked by protrusions 2 and grooves 3, so that adjacent modules form a limiting fit to prevent relative displacement and further ensure stability during use. At the same time, it is easy to install and connect. With the help of pre-embedded steel wire ropes and hooks, the stability is greatly improved.

[0034] The circular platform and the top perimeter of the pedestrian walkway are equipped with several detachable guardrails to ensure pedestrian safety, simplify transportation, and save costs.

[0035] All the protrusions 2 are the same size, and all the grooves 3 are the same size, with each protrusion 2 corresponding to a different groove 3. This facilitates installation and connection.

[0036] All the protrusions 2 are trapezoidal, and the grooves 3 are concentric and coaxial with the corresponding protrusions 2. After the protrusions 2 and the corresponding grooves 3 are tenoned together, they form a limiting fit, and there is a gap between the outer wall of the protrusion 2 and the corresponding groove 3. This leaves space for the hooks 10 to hook together.

[0037] Each of the aforementioned fan-shaped concrete floating plates 1 is embedded with longitudinal steel wire ropes 4 and transverse steel wire ropes 5, and both ends of the longitudinal steel wire ropes 4 and transverse steel wire ropes 5 pass through the side wall of the fan-shaped concrete floating plate 1 and are provided with hooks 10.

[0038] The hooks 10 on the opposite sidewalls of adjacent sector-shaped concrete floating plates 1 are in one-to-one correspondence, and the corresponding hooks 10 are hooked together. The hook 10 on the right side of the sector-shaped concrete floating plate 1 on the left side is hooked onto the corresponding hook 10 on the left side of the sector-shaped concrete floating plate 1 on the right side, further ensuring the fixed stability between the modules.

[0039] The front end of the square concrete floating plate 7, which is closest to the fan-shaped concrete floating plate 1, is arc-shaped, and the arc-shaped end of the square concrete floating plate 7 is tangent to the outer side of the fan-shaped concrete floating plate 1. This ensures a smooth transition between the pedestrian walkway and the circular platform.

[0040] Each of the square concrete floating slabs 7 is embedded with at least one longitudinal steel wire rope 4. The longitudinal steel wire ropes 4 of adjacent square concrete floating slabs 7 correspond one-to-one, and the corresponding longitudinal steel wire ropes 4 are all located in a straight line. The two ends of the longitudinal steel wire rope 4 pass through the side wall of the square concrete floating slab 7 and are provided with hooks 10.

[0041] Preferably, each of the square concrete floating slabs 7 is equipped with two longitudinal steel wire ropes 4, which are symmetrically arranged about the middle position of the square concrete floating slab 7.

[0042] The hooks 10 on the opposite sidewalls of adjacent square concrete floating plates 7 are in one-to-one correspondence, and the corresponding hooks 10 are hooked together. The hooks 10 on the rear side of the front square concrete floating plate 7 are hooked onto the corresponding hooks 10 on the front side of the rear square concrete floating plate 7, further ensuring the fixed stability between the modules.

[0043] In a preferred embodiment 2, both the fan-shaped concrete floating slab 1 and the square concrete floating slab 7 are made of permeable concrete with PP plastic balls as aggregate. Using permeable concrete with PP plastic balls as aggregate as the floating bridge material results in a lighter weight and better stability compared to traditional concrete floating bridges, while also being easier to move. Compared to metal and plastic materials, permeable concrete floating bridges have less impact on aquatic organisms and water quality. The high permeability of permeable concrete allows it to better adapt to different weather conditions; during rainy days, the bridge surface can quickly drain accumulated water, ensuring pedestrian safety.

[0044] As a preferred embodiment 3, each of the guardrails includes two vertical bars 8 and two diagonal bars 6. Each end of the vertical bar 8 is provided with a connector 9, and the two diagonal bars 6 are cross-connected between the two vertical bars 8 through the connector 9.

[0045] The vertical pole 8 is detachably fixed to the top periphery of the module via a base. The connector 9 is a ring-shaped piece, which is fixed to the outer wall of the vertical pole 8 by fasteners. The outer side of the ring-shaped piece is provided with lugs, and the lugs have mounting holes. The diagonal poles 6 cross into an X shape and are then fixed to the corresponding mounting holes by fasteners. The entire guardrail is detachable, which facilitates transportation and further ensures pedestrian safety.

[0046] The working principle of this utility model:

[0047] This utility model utilizes a fan-shaped concrete floating plate 1 to build a circular platform, which is convenient to use;

[0048] The circular platform is decomposed into multiple fan-shaped concrete floating slabs 1, and the pedestrian walkway is decomposed into multiple square concrete floating slabs 7, which facilitates installation and disassembly. At the same time, the fan-shaped concrete floating slabs 1 and the square concrete floating slabs 7 can be prepared in advance and installed on site to form a prefabricated installation, which can be assembled on site.

[0049] The adjacent fan-shaped concrete floating plates 1 and the adjacent square concrete floating plates 7 can be connected by protrusions 2 and grooves 3 to form a tenon joint, so that the adjacent modules form a limiting fit to prevent relative displacement and further ensure stability during use. At the same time, it is easy to install and connect. With the help of pre-embedded steel wire ropes and hooks, the stability is greatly improved.
