Description

Technical Field

[0001] This utility model relates to the field of ship structure technology, and more specifically, to a fireproof bulkhead structure. Furthermore, this utility model also relates to a ship including the aforementioned fireproof bulkhead structure. Background Technology

[0002] Maritime safety has always been a focus of global attention. Fires on ships at sea can cause greater losses than those on land, and in severe cases, can even lead to the sinking of the ship. Therefore, fire prevention requirements for ships at sea are more stringent.

[0003] Fireproofing ship bulkheads is achieved by laying fire-resistant materials on the bulkheads to meet specific requirements. Ship fireproofing requires meeting specific fire resistance time requirements while minimizing material usage to reduce the ship's empty weight. Simultaneously, the installation of fire-resistant materials must be convenient. This leads to higher demands on materials and the specific structure. Currently, to ensure the thinness of the reinforcing members during installation, the reinforcing members are individually wrapped before the flat structure in between is laid, making the construction process cumbersome.

[0004] In conclusion, how to reduce the complexity of fireproof structures is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a fireproof bulkhead structure that can reduce the thickness of the fireproof material at the location of the reinforcing member and avoid the separate construction of the reinforcing member, thereby reducing the construction process.

[0006] Another objective of this invention is to provide a ship that includes the aforementioned fireproof bulkhead structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fireproof bulkhead structure, comprising:

[0009] The bulkhead has several parallel reinforcing members installed on it.

[0010] Several fireproof layers, wherein one of the fireproof layers that is in contact with the bulkhead is laid on the bulkhead in a direction parallel to the reinforcing material, and there is a non-zero included angle between two adjacent fireproof layers.

[0011] Furthermore, the fireproof layers of this invention include a first fireproof layer and a second fireproof layer, wherein the first fireproof layer is arranged parallel to the direction of the reinforcing material, and the second fireproof layer completely covers the reinforcing material.

[0012] Furthermore, in this invention, the first fireproof layer and the second fireproof layer are arranged vertically.

[0013] Furthermore, in this invention, the first fireproof layer and the second fireproof layer have the same or different preset thicknesses.

[0014] Furthermore, the thickness of the first fireproof layer is 30-50mm, and the thickness of the second fireproof layer is 20-40mm.

[0015] Furthermore, in this invention, the density of the fireproof layers is 45~76 kg / m³. 3 .

[0016] Furthermore, in this invention, the fireproof layers are one or more combinations of aluminum silicate fiber, alkaline earth silicate fiber, polycrystalline alumina fiber, or rock wool.

[0017] Furthermore, the present invention provides that the bulkhead is provided with a plurality of fixing posts, and each of the plurality of fixing posts is provided with a limiting piece for fixing the plurality of fireproof layers.

[0018] Furthermore, in this invention, at least one fixing post is provided on each of the two sides of the reinforcing member.

[0019] A ship comprising the fireproof bulkhead structure described in any of the preceding claims.

[0020] The fireproof bulkhead structure provided by this utility model involves covering the bulkhead with several fireproof layers. One layer of fireproof material in contact with the bulkhead is laid parallel to the direction of the reinforcing member, ensuring that both sides of the reinforcing member are covered with at least one layer of fireproof material. Adjacent fireproof layers have a non-zero angle. Through this laying method, another layer of fireproof material is laid outside the fireproof material covering the reinforcing member, and it is not laid parallel to the previous layer. This reduces gaps between adjacent fireproof layers at the through-line and allows it to be laid flat on top of the reinforcing member. This reduces the thickness of the fireproof material at the reinforcing member location, avoids separate construction of the reinforcing member, reduces construction steps, and improves construction efficiency.

[0021] The present invention also provides a ship, including a fireproof bulkhead structure, and has the aforementioned beneficial effects. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The core of this utility model is to provide a fireproof bulkhead structure that can reduce the thickness of the fireproof material at the location of the reinforcing member 2, and avoid the separate construction of the reinforcing member 2, thus reducing the construction steps.

[0030] Another core aspect of this invention is to provide a ship that includes the aforementioned fireproof bulkhead structure.

[0031] Please refer to Figure 2 A fireproof bulkhead structure includes a bulkhead 1 and several fireproof layers. Several parallel reinforcing members 2 are installed on the bulkhead 1. One layer of fireproof material in contact with the bulkhead 1 is laid on the bulkhead 1 in a direction parallel to the reinforcing members 2. There is a non-zero included angle between two adjacent fireproof layers.

[0032] It should be noted that in this embodiment of the utility model, the bulkhead 1 is applied to a ship, and the reinforcing material 2 is a structure that enhances the strength of the bulkhead 1. The reinforcing material 2 is mostly L-shaped steel, which is fixed to the bulkhead 1 by welding and is evenly distributed.

[0033] Optionally, in some embodiments, in order to further improve the coverage strength of the contact area between the fireproof material and the reinforcing member 2, a protrusion is provided on the reinforcing member 2, and the fireproof material is inserted between the protrusion and the bulkhead 1 to achieve the clamping of the fireproof material.

[0034] Optionally, in some embodiments, the number of fireproof layers can be adjusted according to actual use, specifically, determined according to the fire protection rating required by the ship.

[0035] Optionally, in some embodiments, the included angle between two adjacent fireproof materials can be any angle, which can be adjusted according to the shape of the bulkhead 1 during construction, that is, each layer of fireproof material can be laid to cover the entire bulkhead 1.

[0036] In use, several fireproof layers are used to cover the bulkhead 1. One layer of fireproof material in contact with the bulkhead 1 is laid parallel to the direction of the reinforcing member 2, so that both sides of the reinforcing member 2 are covered with at least one layer of fireproof material. The two adjacent fireproof layers have a non-zero angle. Through the above laying method, another layer of fireproof material is laid on the outside of the fireproof material covering the reinforcing member 2, and it is not laid parallel to the previous layer of fireproof material. On the one hand, it can reduce the gap between the two adjacent fireproof materials at the through position, and on the other hand, it can be laid flat on the reinforcing member 2. This can reduce the thickness of the fireproof material at the position of the reinforcing member 2, avoid the reinforcing member 2 being constructed separately, reduce construction steps, and improve construction efficiency.

[0037] Please refer to Figure 1 In some embodiments, the fireproof layers include a first fireproof layer 3 and a second fireproof layer 4. The second fireproof layer 4 completely covers the reinforcing member 2. That is, two fireproof materials are used. The first fireproof layer 3 is laid parallel to the direction of the reinforcing member 2, thus completing the coverage of the entire bulkhead 1 except for the reinforcing member 2. The second fireproof layer 4 is set at an angle to the first fireproof layer. At the same time, the second fireproof layer 4 completely covers the reinforcing member 2. That is, the second fireproof layer 4 is laid directly on the basis of the first fireproof layer 3 and covers the reinforcing member 2 to achieve complete coverage of the entire bulkhead 1. It is not necessary to cover the reinforcing member 2 separately, which reduces the construction difficulty and speeds up the construction efficiency.

[0038] Optionally, in some embodiments, the first fireproof layer 3 and the second fireproof layer 4 are arranged vertically, that is, the first fireproof layer 3 and the second fireproof layer 4 are laid in a cross pattern, which minimizes the gaps at the joint between the first fireproof layer 3 and the second fireproof layer 4 and helps to improve their fire resistance.

[0039] Optionally, in some embodiments, the first fireproof layer 3 and the second fireproof layer 4 have the same or different preset thicknesses. Specifically, the thicknesses of the first fireproof layer 3 and the second fireproof layer 4 can be determined according to the actual needs of use.

[0040] Optionally, in some embodiments, the thickness of the first fireproof layer 3 is 30~45mm, and the thickness of the second fireproof layer 4 is 20~40mm.

[0041] Optionally, in some embodiments, the thickness of the first fireproof layer 3 and the thickness of the second fireproof layer 4 are both 20-50mm, so that the overall thickness of the combination of the first fireproof layer 3 and the second fireproof layer 4 is between 50-80mm, which meets the fire protection requirements.

[0042] In other embodiments, the thickness of the first fireproof layer 3 and the second fireproof layer 4 may also be other thicknesses, such as less than 20 mm or greater than 50 mm.

[0043] Optionally, in some embodiments, the density of the multiple fire-resistant layers is 45~76 kg / m³. 3 .

[0044] In other embodiments, the density of the fire-resistant layers is also different, for example, less than 45 kg / m³. 3 or greater than 76 kg / m 3 .

[0045] Optionally, in some embodiments, the fireproof layers are one or more combinations of aluminum silicate fiber, alkaline earth silicate fiber, polycrystalline alumina fiber, or rock wool.

[0046] Optionally, in some embodiments, the fireproof bulkhead structure consists of a steel bulkhead 1 and aluminum silicate fiber rolls. A 64 kg / m³ aluminum silicate fiber roll is selected as the fireproof material. A 45 mm thick layer of 64 kg / m³ aluminum silicate fiber roll is laid parallel to the reinforcing members 2 between them. Above the reinforcing members 2, a 25 mm thick layer of 64 kg / m³ aluminum silicate fiber roll is laid perpendicular to the reinforcing members 2, passing through steel nails. The two layers of fireproof material are then bonded together. The completed fireproof bulkhead 1 achieves a fire insulation performance of 60 minutes and a fire integrity performance of 60 minutes.

[0047] In other embodiments, the fireproof bulkhead 1 is composed of a steel bulkhead 1 and rock wool rolls. 66kg / m³ rock wool rolls are selected as the fireproof material. A 30mm thick layer of 66kg / m³ rock wool rolls is laid parallel to the reinforcing members 2, passing through steel nails. On top of the reinforcing members 2, a 30mm thick layer of 66kg / m³ rock wool rolls is laid perpendicular to the reinforcing members 2, passing through steel nails. The two layers of fireproof material are then bonded together. The completed fireproof bulkhead 1 achieves a fire insulation performance of 60 minutes and a fire resistance integrity of 60 minutes.

[0048] In other embodiments, the fireproof bulkhead 1 is composed of a steel bulkhead 1 and an alkaline earth silicate fiber roll. A 70kg / m³ alkaline earth silicate fiber roll is selected as the fireproof material. A 40mm thick layer of the 70kg / m³ alkaline earth silicate fiber roll is laid parallel to the reinforcing members 2, passing through steel nails. Above the reinforcing members 2, a 35mm thick layer of the 70kg / m³ alkaline earth silicate fiber roll is laid perpendicular to the reinforcing members 2, passing through steel nails. The two layers of fireproof material are then bonded together. The completed fireproof bulkhead 1 achieves a fire insulation performance of 60 minutes and a fire integrity performance of 60 minutes.

[0049] Please refer to Figure 1 In some embodiments, the bulkhead 1 is provided with a number of fixing posts 5, and each fixing post 5 is provided with a limiting piece 6 for fixing a number of fireproof layers. That is to say, the fireproof material is fixed to the bulkhead 1 by fixing posts 5, and the fireproof material is reinforced by limiting pieces 6 on fixing posts 5.

[0050] Optionally, in some embodiments, the fixing column 5 is fixed to the bulkhead 1 by welding.

[0051] Optionally, in some embodiments, a plurality of fixed columns 5 are evenly distributed and fixed to the bulkhead 1.

[0052] Optionally, in some embodiments, the fixing post 5 can be made of steel nails, which penetrate two layers of fireproof material through the tip of the steel nails, and after the two layers of fireproof material are installed, steel clips are used as limiting pieces 6 to fix it.

[0053] In the above embodiment, the steel card is fixed to the steel nail by a locking mechanism. Specifically, the steel card has a through hole through which the steel nail passes and is fixed to the steel nail.

[0054] Optionally, in some embodiments, at least one fixing post 5 is provided on each side of the reinforcing member 2. That is, a row of fixing posts 5 parallel to the direction of the reinforcing member 2 is provided on both sides of the reinforcing member 2 to increase the fixing strength of the fireproof material.

The two adjacent fireproof layers have a non-zero angle between them. Through the above laying method, another layer of fireproof material is laid on the outside of the fireproof material covering the reinforcing member 2, and it is not laid parallel to the previous layer of fireproof material. On the one hand, it can reduce the gap between the two adjacent fireproof materials at the through position, and on the other hand, it can be laid flat on the reinforcing member 2. This can reduce the thickness of the fireproof material at the position of the reinforcing member 2, and avoid the reinforcing member 2 being constructed separately, reducing construction steps and improving construction efficiency.
