Description
Technical field
The present invention relates to the method and structure that a kind of aluminium electrolysis shop aluminium busbar passes through fire wall, belong to bus technology through walls
Field.
Background technology
Aluminium electrolysis shop is that powerful DC current is conveyed into workshop by many supporting Rectification Power Factors, to transmit electricity
The aluminium busbar that usually high conductivity aluminum material is made of energy.By electric energy principle is transmitted nearby, Rectification Power Factor is generally set
In potroom gable side, aluminium busbar enters either inside by gable side.According to《Code for fire protection design of buildings》Requirement, production
Classification of fire hazards be third, firebreak must reach 10 meters, rectification between two factory buildings that class D fire resistance rating is two grades
Unit classification of fire hazards is Class C, and potroom is class D, therefore the firebreak between two buildings needs to reach 10 meters.
It has been difficult the requirement for meeting 10 meters of firebreak yet with the limitation of present land used scope and other various reasons, therefore,
When firebreak can not meet when requiring of fire safety rules, two solitary buildings need to just be considered to be designed as two of a solitary building
Independent fire compartment, centre is separated by fire wall, and the larger production section of fire risk accounts for this fire compartment area
Ratio need to be less than 5% the classification of fire hazards of whole building, namely fire could be determined by the less part of fire risk
Danger need to be less than the 5% of whole solitary building area for the construction area that the Rectification Power Factor of Class C is configured could press fire risk
Less aluminium electrolysis shop divides the classification of fire hazards of whole solitary building.
After aforementioned condition is met, the classification of fire hazards of whole solitary building can be divided by class D, while two
Separated between independent fire compartment using fire wall, i.e., the gable that aluminium electrolysis shop configures side by Rectification Power Factor must be designed to
The fire wall of any door-window opening can not be opened up.But aluminium busbar is worn gable and punched unavoidably, so aluminium busbar wears fire prevention
The fire-proof insulation closure processing that wall punches just seems particularly especially and important.
The content of the invention
It is an object of the present invention to provide a kind of aluminium electrolysis shop aluminium busbar passes through the method and structure of fire wall.To carry
High bus passes through fire prevention and the insulation rank of fire wall, eliminates safe hidden trouble, so as to overcome the deficiencies in the prior art.
The technical proposal of the invention is realized in this way：
The method that a kind of aluminium electrolysis shop aluminium busbar of the present invention passes through fire wall is that this method is constructed according to the following steps：
Step 1: opening cable-through hole on fire wall according to the section and quantity for passing through fire wall aluminium busbar；
Step 2: aluminium busbar is passed through from cable-through hole, and with glass fabric of epoxy resin laminate by fire wall both sides
Cable-through hole is blocked；
Step 3: blocking the gap of fire wall both sides aluminium busbar surrounding with fire-proof plate；Use rock wool in gap between aluminium busbar
Filling closure；
Aperture is surrounded Step 4: building enclosure wall in fire wall both sides；
Step 5: filling sand within the walls by fire-proof plate surrounding jam-packed；
Step 6: will be covered tightly with armored concrete removable cover at the top of enclosure wall.
In preceding method, the cable-through hole in step one is rectangular opening.
In preceding method, the glass fabric of epoxy resin laminate model R3240 in step 2；Glass fabric of epoxy resin layer
Pressing plate is square annular, and its outward flange is more than 200mm apart from the distance of cable-through hole, is fixed on by expansion bolt on fire wall, ring
Clogged between oxygen tree fat glass cloth laminated board and fire wall with fireproof gum.
In preceding method, the fire-proof plate in step 3 is rectangular drum like, and fire-proof plate stretches out the length of fire wall cable-through hole both sides
Degree is not less than 1 meter respectively, and the fire endurance of fire-proof plate is identical with fire wall and more than 3h；, epoxy resin is filled in fire-proof plate one end
In the gap of glass cloth laminated board and aluminium busbar and with fire prevention glue sticking.
In preceding method, the enclosure wall in step 4 is shaped as a font, surrounds cable-through hole from three faces；The height of enclosure wall is high
It is high in punch hole top mark of aluminium busbar；Enclosure wall is constructed using ordinary fired brick, air-entrained concrete building block or lightweight concrete, and wall is thick
Degree is determined according to the requirement of total fire endurance ＞ 3h comprising face thickness of plastering.
In preceding method, the sand in step 5 uses the mixed sand of two kinds of different-grain diameters；A kind of is particle diameter ＞ 2mm
Sand, another is particle diameter ＞ 0.075mm sand；Particle diameter ＞ 2mm sand is no more than the 50% of gross mass, and remaining is particle diameter ＞
0.075mm sand.
The structure that a kind of aluminium busbar of the invention constituted as stated above passes through fire wall is that the structure includes fire prevention
Wall, fire wall is provided with cable-through hole, and the aluminium busbar is passed through from cable-through hole；Epoxy resin is provided with the aperture at cable-through hole two ends
Glass cloth laminated board, glass fabric of epoxy resin laminate is connected with fire-proof plate；Cable-through hole two ends are provided with enclosure wall, and enclosure wall is door word
It is provided with shape, enclosure wall at the top of sand, enclosure wall and is provided with armored concrete removable cover.
By adopting the above-described technical solution, the present invention is compared with prior art, the invention has the characteristics that：One is to adopt
Use glass fabric of epoxy resin laminate（R3240）, different from commonly carrying out fireproof blocking only with rock wool, laminate can play fire-retardant
Insulating effect, and its feature stability is more superior under hot and humid environment.Two be on glass fabric of epoxy resin laminate basis
On, then the fire-proof plate of equivalent fire wall fire endurance is set along cable-through hole surrounding, double-deck fireproof blocking effect is prevented fires better than individual layer and sealed
Stifled effect.Three be that real body of building a wall is enclosed, and internal back-up sand soil, effect is fully and completely to completely cut off two different fire compartments, is
More preferable protection setting facilitates the later stage to take off lid and safeguarded, together in designing concrete removable top cover on this outdoor Construction treatment, Gu Ding
When play rain cover, personnel and pass through effect safe herein.
