When in use, since the fire-resisting bulkhead of the ship is produced by the nano-hole heat-insulating material and the nano-hole heat-insulating material is a heat guard consisting of gaps of not more than 100nm, the fire-resisting bulkhead of the ship can well limit the heat convection of the heat-insulating material and realize great heat-insulating performance, and the heat-insulating advantage of the fire-resisting bulkhead of the ship can be particularly represented under the condition of high temperature. The fire-resisting bulkhead of the ship has the characteristics of light weight of the heat-insulating layers, reasonable structure, thin thickness and high fire resistance rating; and the structure of the fire-resisting bulkhead can achieve the A-60 grade fire resistance rating of the ship bulkhead by only needing the heat-insulating layers with the thickness of 21mm, and obtain the effects of reducing the weight and saving the space.
Description
Technical field:
The utility model relates to the technical field of boats and ships, specifically a kind of fire resisting bulkhead structure of boats and ships.
Background technology:
The effect of boats and ships fire resisting bulkhead is under the hot conditions of fire burns, requires to be no more than 140 ℃ in the one side mean temperature of its back of the body fire, and the vertex temperature is no more than 180 ℃.
The boats and ships fire resisting bulkhead is divided into A level, B level etc. according to the difference of boats and ships fire protection requirement, can be divided into 0,15,30,60 minute again etc. according to the limit of fire resistance period.Highest ranking in present boats and ships fire protection requirement is the A-60 level.
In the manufacturing technology of existing boats and ships fire resisting bulkhead, fire resisting bulkhead normally adds that by the framing member that steel sheet material and stiffener are made thermal insulating material is formed, and wherein employed thermal insulating material has alumina silicate fibre, soluble silicate fiber and rock wool etc.But the effect of heat insulation of above mentioned these thermal insulating materials is also bad, and making just needs thicker thickness just can reach higher fire endurance rating as the boats and ships fire resisting bulkhead time.As boats and ships A-60 level fire resisting bulkhead the time, alumina silicate fibre needs the thickness of 40mm, the thickness that the soluble silicate fiber needs 63mm, the thickness that rock wool needs 70mm, and the weight per unit area of thermal insulation layer has all surpassed 7kg/m2.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved boats and ships fire resisting bulkhead, and it can overcome in the prior art effect of heat insulation and bad, needs thicker thickness just can reach the some shortcomings of higher fire endurance rating.
To achieve these goals, the technical solution of the utility model is: a kind of boats and ships fire resisting bulkhead, and it mainly comprises the wallboard base material, it is characterized in that: the wallboard base material is provided with stiffener, the surface of wallboard base material and stiffener is provided with thermal insulation layer, and thermal insulation layer is made by nano-pore heat insulating materials.
Adopted a kind of nano-pore heat insulating materials to make the boats and ships fire resisting bulkhead in the utility model basis during use, because nano-pore heat insulating materials is the heat guard that the space was constituted with≤100nm, can limit the heat convection of thermal insulating material well, therefore have good heat-insulating property, particularly the adiabatic advantage under hot conditions more can embody.The characteristics that this boats and ships fire resisting bulkhead has that thermal insulation layer is in light weight and rational in infrastructure, thin thickness, fire endurance rating are high, the fire resisting bulkhead structure only needs the thermal insulation layer thickness of 21mm just can reach the boats and ships bulkhead fire endurance rating of A-60 level, can obtain expendable weight and space-saving effect.

Fig. 2 is the another structural representation of the utility model one embodiment
Fig. 3 arranges scheme drawing for the nail that bumps of the present utility model.
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises wallboard base material 1, and its difference with the prior art is: the wallboard base material is provided with stiffener 2, and the surface of wallboard base material and stiffener is provided with thermal insulation layer 3, and thermal insulation layer is made by nano-pore heat insulating materials.Thermal insulation layer is laid by the layer 2-4 nano-pore heat insulating materials and is formed, and the levels nano-pore heat insulating materials carries out arranged in dislocation at edge joint position, and the nano heat insulating material of the superiors adopts the stepped ramp type bridging arrangement at edge joint position.The wallboard base material adopts the thick steel plate of 5mm, and stiffener adopts the L structural section, adopts between wallboard base material and stiffener and the thermal insulation layer to bump nail 4 and captive joint, and the thermal insulation layer at stiffener place is to install and fix with the form that nano-pore thermal insulation material is made a kind of sleeve.Coefficient of thermal conductivity≤the 0.050w/mk of nano-pore heat insulating materials under 500 ℃ of high temperature.The unit weight of its core of nano-pore heat insulating materials is at 180-220kg/m
3, the surface is coated with the thick high silica glass cloth of 0.14-2.0mm.
In force, be the fire resisting bulkhead plate substrate with the thick steel plate of 5mm, be welded on the steel plate as stiffener along the vertical dimension direction with the L structural section of 65 * 65 * 5mm, the spacing of stiffener and stiffener is 550mm.Welding diameter on the plane of steel plate is that the steel of 3mm bumps nail, the bumping nail and arrange it is between per two stiffeners, to establish two to bump nail of horizontal direction, and two are bumped distance between the nail about 300mm.In the vertical direction of steel plate is to lay in per two nano-pore heat insulating materials lap-joints of outermost layer thermal insulation layer to bump nail, adds about the every 300mm of vertical direction and bumps nail, bumps nail in about 30mm place, two ends laying up and down in addition.Lay on the top end face of stiffener and bump nail, installing sleeve is also fixed.
