Abstract
The invention discloses a fire wall with a grass root imitated structure. The fire wall is formed by sequentially gluing or connecting a thermal insulation layer, strength layers on two sides of the thermal insulation layer and fire protection layers on two sides of the strength layers, wherein the thermal insulation layer is made of a material with heat conductivity coefficient less than 0.5W/(m.k); the compressive strength of the strength layer is required to be 30MPa-500MPa, and the fire resistance rating belongs to a first level or a second level; the fire-protection rating of the fire protection layers is required to be grade A or grade B1, and the fire resistance rating belongs to a first level or a second level; the sound insulation capability of the whole fire wall is 55dB-65dB. The fire wall is of a grass root imitated structure, firstly fire can not directly damage the wall due to the fire protection layers on the outer side, and secondly the strength layers ensure that the wall can not be damaged due to high temperature, so that the fire protection effect of the wall is ensured; finally the middle thermal insulation layer prevents heat from penetrating through the wall, so that the volume of noises penetrating through the wall is reduced. When encountering with a fire disaster, the fire wall is capable of controlling fire within a certain range, so that damage caused by the fire disaster can be reduced.
Description
Technical field
The present invention relates to a kind of building wall, particularly relate to a kind of fire wall of imitative grass roots structure.
Background technology
Increasingly sophisticated along with human lives's study and work environment, gets more and more to the requirement of building safety.The height of building increases year by year, and internal unit is also increasing, and potential safety hazard is also increasing.At present, the maximum potential safety hazard of highrise building is caught fire, first it is all high-molecular organic material that present constructional materials has a lot, the wallpaper, compressed cardboard, plank etc. of inner wall of building are all combustibles, and indoor furniture, electric equipment, bed by etc. great majority all flammable, the possibility of therefore catching fire is very large; And the intensity of a fire can, along body of wall or from window to vertical spread, be difficult to control; High level fire fighting difficulty of catching fire is large, and the fire fighting of catching fire of present high level can only be put out a fire with small-sized fire-extinguishing apparatus, has little effect and is unable to catch up with the speed of fire spreading even far away, therefore prevents highrise building fire spreading should from the viewpoint of the structure and material of building itself.
Summary of the invention
The object of the present invention is to provide a kind of fire wall of imitative grass roots structure.Such building wall fireprotection layer when meeting with fire can prevent body of wall from catching fire, and prevents the intensity of a fire from spreading along wall; Strength layer can protect body of wall can not collapse because of temperature distortion when meeting with fire; Isolation layer can ensure effect of heat insulation and the soundproof effect of body of wall.
The technical solution used in the present invention is:
The strength layer of the present invention by isolation layer, isolation layer both sides and the fireprotection layer of strength layer both sides, between layers by pasting or being formed by connecting.
The material of described isolation layer, its coefficient of thermal conductivity is less than 0.5W/ (mK); Strength layer requires that compressive strength is 30MPa to 500MPa, and fire resistance rating is one-level or secondary; Fireprotection layer requires that fire-protection rating is A level or B1 level, and fire resistance rating is one-level or secondary; The sound insulation capabilities of whole fire wall is 55dB to 65dB.
Described insulating layer material is foam concrete, sheet asbestos, pulpboard or air.
Described strength layer material is portland cement, cement concrete, bituminous concrete, plaster concrete, polymer concrete, MU30 clinker brick or MU30 porous brick.
Described fireprotection layer material is gypsum plank, lime goods, clay-ware, glass, ceramic tile, cement products, marble, granite or terrazzo concrete.
The beneficial effect that the present invention has is:
The present invention imitates grass roots structure, improve building fire protection ability, first by two outside layers fireprotection layer, fire can not be produced to wall directly to destroy, next fire resistance rating is that the strength layer of secondary or one-level ensure that wall can not by high temperature, this two promise flameproof effect of wall, the isolation layer of last centre blocks heat through body of wall, reduces noise through the volume after wall.This fire wall by fire control built in certain limit, can reduce the harm of fire when meeting with fire.
Accompanying drawing explanation
Fig. 1 is grass roots structure chart.
Fig. 2 is fire rated wall structure schematic diagram.
Wherein: 1, epidermis, 2, cortex, 3, vascular cylinder, 4, fireprotection layer, 5, strength layer, 6, isolation layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1; grass roots structure comprises epidermis 1, cortex 2 and vascular cylinder 3; epidermis 1 cell arrangement is closely neat; protection cortex 2 is from the impact of soda acid in soil and microorganism; cortex 2 is chief components of grass roots; make grass roots have certain intensity and toughness, ensure the grass roots direction of growth, vascular cylinder 3 is primary tissues of grass roots.
As shown in Figure 2, fire wall of the present invention imitates grass roots structure, from the inside to the outside successively by the strength layer 5 of isolation layer 6, isolation layer 6 both sides and the fireprotection layer 4 of strength layer 5 both sides, between layers by pasting or being formed by connecting.
The material of isolation layer 6, its coefficient of thermal conductivity is less than 0.5W/ (mK); Strength layer 5 requires that compressive strength is 30MPa to 500MPa, and fire resistance rating is one-level or secondary; Fireprotection layer 4 requires that fire-protection rating is A level or B1 level, and fire resistance rating is one-level or secondary; The sound insulation capabilities of whole fire wall is 55dB to 65dB.
Isolation layer 6 material is foam concrete, sheet asbestos, pulpboard or air.Strength layer 5 material is portland cement, cement concrete, bituminous concrete, plaster concrete, polymer concrete, MU30 clinker brick or MU30 porous brick.Fireprotection layer 4 material is gypsum plank, lime goods, clay-ware, glass, ceramic tile, cement products, marble, granite or terrazzo concrete.
Such building wall fireprotection layer 4 when meeting with fire can prevent body of wall from catching fire, and prevents the intensity of a fire from spreading along wall; Strength layer 5 can protect body of wall can not collapse because of temperature distortion when meeting with fire; Isolation layer 6 can ensure effect of heat insulation and the soundproof effect of body of wall.
