Description

Technical Field

[0001] The utility model relates to the technical field of floating buildings, in particular to a full-light reinforced concrete load-bearing pontoon. Background Art

[0002] Most of the pontoons in China are plastic pontoons and fiberglass pontoons, and concrete pontoons are still in their infancy. Plastic pontoons have many defects, poor aging performance, sunlight exposure, plastic hydrolysis and water absorption will cause aging. In addition, salt water erosion, alternating hot and cold, microbial erosion, etc. will also accelerate the aging of plastics. The service life of a 12cm thick plastic pontoon is only 10-15 years. Although the life span can be extended after spraying anti-corrosion facilities, once the anti-corrosion layer is consumed, it will also reach the end of its life. Discarded plastics have no use value and become white pollutants, which will cause severe pollution to the marine environment. The production process of fiberglass pontoons is relatively complicated, and the price is twice that of plastic pontoons. The fiberglass production process produces huge toxicity, which is harmful to the human body, and damage and recycling will also produce great toxicity. It is generally not recommended for use.

[0003] Concrete pontoons are pollution-free, inexpensive, have good mechanical properties, and strong impermeability. Therefore, the development and research of concrete pontoon carriers has great practical significance.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] See also Figure 1-6 A fully light reinforced concrete load-bearing pontoon comprises a pontoon body 100 of a reinforced concrete structure, the pontoon body 100 having a cavity therein, a transverse partition 110 being arranged in the cavity of the pontoon body 100, the partition 110 dividing the cavity into a closed bin 140 located below and a receiving bin 150 located above the closed bin 140, a lower partition wall 120 being arranged in the closed bin 140, an upper partition wall 130 being arranged in the receiving bin 150, the lower partition wall 120 and the upper partition wall 130 dividing the closed bin 140 and the receiving bin 150 into a plurality of spaces respectively. By setting a partition 110 in the pontoon body 100, the partition 110 divides the internal cavity of the pontoon body 10 into a closed chamber 140 and a receiving chamber 150, a lower partition wall 120 is set in the closed chamber 140, and an upper partition wall 130 is set in the receiving chamber 150. The lower partition wall and the upper partition wall divide the closed chamber and the receiving chamber into multiple spaces respectively. When the area of ​​the pontoon body is designed to be larger, the pontoon body also has a higher structural strength, thereby improving the reliability of the pontoon body.

[0030] The multiple spaces formed by the lower partition wall 120 in the closed chamber 140 can not only improve the structural strength of the pontoon body 100, but also play a role in isolating leakage, that is, if there is leakage at the bottom of one of the spaces, water will only leak into this space.

[0031] In one embodiment, the total weight of the load-bearing pontoon is 3,700 tons, the volume is 11,880 m³, and the buoyancy can reach 69%.

[0032] Specifically, all-light reinforced concrete is a prior art. For example, patent document CN105084833A discloses a high-strength thermal insulation all-light concrete and a preparation method thereof.

[0033] See also Figure 1-3 The upper partition wall 130 in the storage tank 150 is provided with a passage 131, and the top of the pontoon body 100 is provided with a hole 101, which is connected to the storage tank 150. In this way, people can enter the storage tank 150 through the hole 101, and the storage tank 150 can be loaded with goods and people, and the passage 131 also reduces the overall weight of the pontoon body 100.

[0034] Since the closed chamber 140 is fully closed, in order to realize the integral casting of the partition 110, see Figure 2 , the top of each space in the closed bin 140 , and a support platform 160 is installed on the lower side of the partition 110 , and when the partition 110 is poured, concrete is poured on the support platform 160 .

[0035] For further information, see Figure 5 ,6 The supporting platform 160 includes a main beam 161, a secondary beam 162 and a template 163. A plurality of main beams 161 are arranged at intervals, and a plurality of secondary beams 162 are fixedly connected between adjacent main beams 161. The template 163 is located above the secondary beams 162. The main beams 161 and the secondary beams 162 can be made of wood or light steel. Figure 2 A notch 121 is provided at the top of each space in the closed compartment 140 , and both ends of the main beam 161 are installed in the notch 121 to realize the installation of the support platform 160 .

[0036] For further information, see Figure 4 Since a notch 121 needs to be provided at the top of each space in the closed compartment 140, the support platforms 160 in each column or row are staggeredly installed, and the positions of the notches 121 can be staggered, thereby ensuring the overall structural strength of the pontoon body 100.

[0037] When the template 163 is installed, the template 163 can be located above the main beam 161 and the auxiliary beam 162, or the template 163 can be located between adjacent main beams 161, and the upper side surface of the template 163 is flush with the upper side surface of the main beam 161.

[0038] For further information, see Figure 5 A plurality of connecting piles 164 are provided on the upper side of the main beam 161. When the partition 110 is cast, the connecting piles 164 are embedded in the partition 110, so that the main beam 161 and the partition 110 are connected and fixed, thereby improving the structural strength of the partition 110.

[0039] In this embodiment, the thickness of the lower partition wall 120 and the upper partition wall 130 is smaller than the thickness of the side wall of the pontoon body 100 .

[0040] Specifically, the top and bottom surfaces of the pontoon body 100 are double-layer reinforced concrete with a thickness of 0.3m, the surroundings of the pontoon body 100 are double-layer reinforced concrete with a thickness of 0.2m, and the partition 110, the lower partition wall 120 and the upper partition wall 130 are single-layer reinforced concrete with a thickness of 0.1m.

[0041] Furthermore, a protective layer is provided on the outer wall around and at the bottom of the buoyancy chamber body 100 .

[0042] Specifically, the protective layer includes a waterproof coating and / or an antifouling coating. The waterproof coating plays a role in waterproofing and anti-leakage, and the antifouling coating plays a role in preventing the attachment of aquatic organisms. The waterproof coating and the antifouling coating are respectively achieved by applying a waterproof coating and an antifouling coating.

[0043] In one embodiment, the full light concrete comprises the following raw material components in parts by weight:

[0044] 45-60 parts of shale ceramsite, 40-55 parts of ceramic sand, 5-10 parts of silica fume, 0.2-0.6 parts of steel fiber, 1.5-4 parts of fly ash, and 0.8-1.5 parts of water reducer.

[0045] After testing, the water penetration depth of 40MPa light concrete and 80MPa ordinary concrete under the water pressure of 3.5MPa is 0.5cm, that is, the depth of water penetrating into the concrete is 0.5cm. Frost resistance: After 28 days of standard curing and 54 freeze-thaw cycles, there is no loss of strength and a weight loss of 0.25%. After 28 days of standard curing, carbonization is zero, there is no alkali-aggregate reaction condition, and the seismic performance is also very good.
