Description

Technical Field

[0001] The utility model relates to the field of pontoon manufacturing, and more specifically, relates to a spliced ​​modular concrete pontoon. Background Art

[0002] A pontoon is a flat-bottomed boat without a power plant, primarily used for fixed-position water platforms, docks, floating bridges, and other facilities. A pontoon cannot sail on its own and is usually moved by tugboats or other vessels.

[0003] Common concrete pontoons mostly adopt an integral manufacturing process, which specifically includes slipway erection, laying of bottom formwork, tying of bottom plate steel bars, installation of prefabricated side plates / partitions on the slipway's cast-in-place bottom plate, side plate joint connection and concrete pouring, laying of surface bottom formwork, tying of surface steel bars, and then pouring of surface panel concrete. The pontoon is then launched as a whole and towed to the site of use by water for installation.

[0004] The above process requires a large-scale manufacturing site such as a slipway or dock on the sea or river bank, which limits the manufacturing space. In addition, since concrete construction takes a long time, it takes at least three months to cast a concrete pontoon in its entirety, resulting in a long on-site manufacturing time for the pontoon.

[0005] In addition, there are also some pontoons that rely on steel structures spliced ​​on-site with bolt fasteners. This type of pontoon has limited wind and wave resistance and is prone to fracture damage at rigid connections. Utility Model Content

[0027] In combination with the actual situation, the pontoon manufacturing method of the whole pouring of the concrete has the following deficiencies:

[0028] 1. The manufacturing site must be arranged in a large manufacturing berth / dock at the sea / river bank

[0029] 2. The concrete can only be naturally maintained, and the construction time is long. It takes at least three months to manufacture a whole concrete pontoon, and the time is long.

[0030] 3. The manufacturing site and the use site should not be too far apart, and they must be connected by waterway, otherwise it cannot be delivered.

[0031] 4, the speed of the towing process is slow, the time is long, and there are many safety hazards in the towing process.

[0032] 5, unable to make in closed water.

[0033] 6, the demolition process has a great impact on the water environment and is not environmentally friendly.

[0034] In order to solve the above problems, the present application has the following design:

[0035] Embodiments

[0036] As Figures 1-5 A spliced modular concrete pontoon, comprising sections 1, baffles 2 and steel strands 3, the outermost of the sections 1 is a baffle 2 for blocking, and the sections 1 are reinforced by post-tensioning in the horizontal and vertical directions, and all the sections 1 are strung together to form a pontoon structure with an area and strength meeting the use requirements.

[0037] Compared with the existing steel structure, the concrete is more corrosion-resistant, has lower maintenance cost and longer service life.

[0038] Compared with the common splicing method of fastening screws, the post-tensioning reinforcement method increases a prestress between the sections 1 in the horizontal and vertical directions, reduces the development of concrete cracks, and also leaves a certain relative movement space between the sections 1, reducing the destructive effect of wave force on the overall structure of the pontoon.

[0039] The section 1 comprises a plurality of prefabricated plates, which can be divided into a bottom plate 11, a side plate 12 and a cover plate 13, and the bottom plate 11, the side plate 12 and the cover plate 13 are all pre-processed in the factory and have a steel reinforcement frame embedded inside to improve the strength.

[0040] The bottom plate 11 and the cover plate 13 are symmetrically arranged at the lower and upper positions of the section 1, and four side plates 12 mutually forming a right angle are inserted between the bottom plate 11 and the cover plate 13, so that a cavity is formed inside the section 1, the volume of the cavity and the overall weight of the section 1 meet the buoyancy requirements, and the bottom plate 11 and the cover plate 13 are pre-embedded with positioning tube sleeves, and the side plate 12 is pre-embedded with positioning nails on the upper and lower sidewalls, which can be inserted into the positioning tube sleeves to position the bottom plate 11, the side plate 12 and the cover plate 13.

[0041] A connecting piece 4 is needed during actual installation to connect the side plate 12 with the corresponding bottom plate 11 and cover plate 13, and the connecting piece 4 specifically comprises an angle adjusting rod 41 and a limiting plate 42.

[0042] The angle adjusting rod 41 comprises a base plate 411, a rod one 412 and a rod two 413, bolt holes are pre-buried on the bottom plate 11, the side plate 12 and the cover plate 13, the base plate 411 comprises a plate body and a bolt which are rotationally connected with each other, the plate body is rotationally connected with the rod one 412 and the rod two 413 respectively, the bolt is threadedly connected with the corresponding bolt hole, the rod two 413 is slidably arranged in the rod one 412, a nut is rotationally connected on the end of the rod one 412, the nut is threadedly connected with the outer sidewall of the rod one 412, by screwing the nut, the overall length of the rod one 412 and the rod two 413 can be adjusted, so that the angle between the two prefabricated plates connected with the angle adjusting rod 41 can be adjusted to meet the angle accuracy requirement.

[0043] The limiting plate 42 is used for guiding the side plate 12 to enter the bottom plate 11, and the limiting plate 42 is detachably connected to the bottom plate 12.

[0044] In use, the bottom plate 11 is laid on the pre-levelled base, the side plate 12 is hoisted by the crane, the corresponding side plate 12 is slid into the bottom plate 11 by the guiding ability of the limiting plate 42, and the positioning nails are inserted into the positioning tube sleeve, at this time, the user connects the base plate 411 to the pre-buried bolt holes of the bottom plate 11 and the side plate 12, and then adjusts the overall length of the angle adjusting rod 41 by screwing the nut, so that the angle between the bottom plate 11 and the side plate 12 can be adjusted, the side plate 12 can be tightly attached to the sidewall of the limiting plate 42 and be at a right angle with the bottom plate 11, and then the limiting plate 42 can be removed.

[0045] The above steps are repeated until the three side plates 12 are connected to the bottom plate 11 at right angles.

[0046] Then the cover plate 13 is closed, and the cover plate 13 and the side plate 12 are connected by the angle adjusting rod 41.

[0047] The specially-made concrete is used to pour and grout the steel reinforcement framework which extends horizontally and outwardly from the four side plates 12, and the grouted surface is scraped and then solidified.

[0048] The specially-made concrete can seal the gaps at the intersections and fasten the connection between the bottom plate 11, the side plate 12 and the cover plate 13.

[0049] It should be noted that the specially-made concrete can be quick-setting concrete, polymer concrete and other types of concrete with good viscosity and fast solidification characteristics.

[0050] The outer wall of the bottom plate 11, the cover plate 13 or the side plate 12 is provided with a positioning pin and a positioning hole, when two sections 1 are spliced, the positioning pin is inserted into the positioning hole of the other section 1 to achieve the purpose of preliminary positioning.

[0051] The outer wall of the side plate 12 is provided with a glue groove at the beginning of molding, and the user pours a gelling agent into the glue groove, and after the gelling agent solidifies, two segments 1 are obtained which are spliced together.

[0052] The so-called post-tensioning prestressed reinforcement mode is specifically as follows: first, a plurality of segments 1 are placed on the leveled base, then a steel strand 3 is sequentially threaded through the reserved holes reserved on the prefabricated plate in the longitudinal direction, and a baffle 2 is arranged at the outermost side of the plurality of segments 1, after the steel strand 3 passes through the baffle 2, the end of the steel strand 3 is fixed outside the baffle 2 by an anchor, so as to string the plurality of segments 1 into a string; then the above-mentioned behavior is repeated to obtain a plurality of strings of segments 1, and then the steel strand 3 is transversely threaded through the plurality of segments 1 to splice the plurality of strings of segments 1 into a whole, thus preliminarily obtaining a pontoon that can float on the water.

[0053] When the above-mentioned pontoon enters the water, even if it encounters a case where the water surface surge is relatively large, the prestressed connection mode is more flexible.

[0054] The advantages of the present scheme include:

[0055] 1. The present scheme does not require a special large pontoon building berth, and the prefabricated plate can be produced by a production line of a concrete factory near the use site, so the cost is lower.

[0056] 2. The application range of the present scheme is wider, which can be used not only in river and sea areas, but also in lake, reservoir and other closed water areas for shipbuilding.

[0057] 3. The construction period is short, the prefabricated plate can be produced in advance at a concrete factory near the use site, and steam curing or other new materials are used, so the production time is greatly reduced.

[0058] 4. The present scheme does not involve long-distance water transportation, so the transportation cost can be greatly reduced, and the construction safety can be improved.

[0059] 5. The present scheme provides a good method for far-sea water construction, such as the rapid construction of wharfs on the South China Sea islands.

[0060] 6. The present scheme uses factory production, so the quality is more controllable and better, the product durability is better, and the design service life can reach 50 years.

[0061] 7. The present scheme is environmentally friendly, the ship body can be dismantled and treated after the service life, which is convenient for environmental protection.

[0062] 8. The pontoon made by the present scheme does not need to be maintained regularly like a steel pontoon.

[0063] It should be noted that the above-mentioned side plates 12 are at right angles to each other, and the side plates are four, which are only examples, and in actual application, other angles and numbers can be designed.

[0064] The above merely describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application by those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
