Referring to fig. 1, the present embodiment provides a fire wall 100, which includes a base, a steel structure supporting frame 10 disposed on the base, a first composite board wall 20 disposed on an outer side of the steel structure supporting frame 10, and a second composite board wall 30 disposed on an inner side of the steel structure supporting frame 10, wherein the first composite board wall 20 includes a fiber cement board 21, and the second composite board wall 30 includes a fire-proof gypsum board 31. The fireproof wall 100 can meet the fireproof requirements of a transformer substation.
It should be noted that, firstly, the fireproof wall 100 includes a base, a steel structure supporting frame 10, a first composite panel wall 20 and a second composite panel wall 30. Wherein, steel construction support frame 10 sets up on the base to provide the installation basis for steel construction support frame 10 through the base. First composite board wall 20 sets up in the outside of steel construction support frame 10, and first composite board wall 20 includes fiber cement board 21 to provide fire protection for the outside of steel construction support frame 10 through fiber cement board 21. The second composite board wall 30 is arranged on the inner side of the steel structure supporting frame 10, and the second composite board wall 30 comprises a fireproof gypsum board 31 so as to provide fireproof protection for the outer side of the steel structure supporting frame 10 through the fireproof gypsum board 31.
Secondly, fiber cement board 21 (FC board) is a board made by using cement as basic material and adhesive, mineral fiber cement and other fibers as reinforcing material, and through processes of pulping, forming, curing, etc., and is widely used in various fields of building industry due to its superior performance. The fiber-reinforced cement board is classified into a chrysotile fiber cement board 21 and a non-asbestos fiber cement board 21 according to the difference of the added fibers, and is classified into a fiber cement non-pressure board and a fiber cement pressure board according to the difference of molding and pressurizing.
The fiber cement board 21 has the following advantages: (1) fireproof insulation: the fire-retardant plate is non-combustible in grade A, so that the plate cannot burn in case of fire and toxic smoke cannot be generated; the conductive coefficient is low, so that the insulating material is an ideal insulating material and is suitable for being applied to places such as transformer substations and the like. (2) Waterproof and moistureproof: the performance can be kept stable and does not sink or deform in the semi-open air and high humidity environment. (3) Heat and sound insulation: low heat conductivity coefficient, good heat insulation performance, high product density and good sound insulation. (4) Light weight and high strength: the plate pressed by the 5000-ton flat plate oil press has high strength and is not easy to deform and warp; the weight is small, and the device is suitable for roof suspended ceilings and other aspects. (5) The construction is simple: and in a dry operation mode, the installation and construction of the keel and the plate are simple and fast. The deep processed product also has the characteristics of simple and convenient construction and better performance. (6) Economic and beautiful: the light weight, the cooperation with fossil fragments, effectively reduce engineering and fitment cost; the appearance color is uniform, the surface is smooth, and the color of the building surface can be uniform by direct use. (7) Safety and harmlessness: is lower than the building material radiation health protection standard in the industry, and the actually measured index is equal to the lawn value which is twenty meters away from the surrounding buildings. (8) The service life is super long: acid and alkali resistance, corrosion resistance, no damage by moisture or insects and ants and the like, and the strength and the hardness are enhanced along with time, thereby ensuring the super-long service life. (9) The machinable and secondary decoration performance is good: the material can be sawed, drilled, carved, nailed, coated, pasted with ceramic tiles, wall cloth and the like according to the actual situation.
Thirdly, the Fire-proof gypsum board 31 (English name: Fire prevention plasterboard) is a new product innovated and developed on the basis of the traditional gypsum plaster board, not only has the characteristics of sound insulation, heat preservation, light weight, high strength, small shrinkage rate and the like of the gypsum plaster board, but also adds some additives (glass fiber) in the core of the Fire-proof gypsum board 31, so that the board keeps structural integrity (in a building structure) within a certain time when the board catches Fire, thereby playing a role in obstructing the propagation of precious flame and striving for escape time. Besides the performance of the standard gypsum board with Bayer positioning points, the gypsum board also has higher fireproof performance, and the fireproof time is longer than 60 minutes.
The fire-proof principle of the fire-proof gypsum board 31 lies in the core of the fire-proof gypsum board 31: one, CaSO4·2H2O, crystal water of the fire-retardant gypsum board 31 is an important reason for its fire-retardancy. When the fireproof gypsum board 31 is on fire, the free moisture in the board core evaporates out, absorbs a small amount of heat and reduces the temperature around the board. When the temperature continues to rise, the crystal water of the dihydrate gypsum begins to separate and is decomposed into gypsum and moisture, and a large amount of heat needs to be absorbed in the process, so that the temperature rise around the board surface can be influenced in a long time. Secondly, the main reason for the fire-resistant failure of the fire-resistant gypsum board 31 is that the dihydrate gypsum shrinks in volume after removing the crystal water and loses its integrity to be powdery, and in order to improve the fire resistance of the fire-resistant gypsum board 31, some additives must be added to the core of the fire-resistant gypsum board 31. The fire-resistant material which expands when encountering fire and a large amount of fire-resistant glass fibers are added into the fire-resistant paper-surface gypsum board, so that the whole volume is ensured to be unchanged while the gypsum contracts, and the gypsum core material is pulled and bonded together so as not to lose the integrity, thereby ensuring that the fire-resistant gypsum board 31 has higher fire resistance.
As described above, the firewall 100 includes a base, a steel structural support frame 10, a first composite panel wall 20, and a second composite panel wall 30. Wherein, steel construction support frame 10 sets up on the base to provide the installation basis for steel construction support frame 10 through the base. First composite board wall 20 sets up in the outside of steel construction support frame 10, and first composite board wall 20 includes fiber cement board 21 to provide fire protection for the outside of steel construction support frame 10 through fiber cement board 21. The second composite board wall 30 is arranged on the inner side of the steel structure supporting frame 10, and the second composite board wall 30 comprises a fireproof gypsum board 31 so as to provide fireproof protection for the outer side of the steel structure supporting frame 10 through the fireproof gypsum board 31. This fire wall body 100 is located between the two through the combined action of first composite board wall 20 and second composite board wall 30 with steel construction support frame 10 clamp to steel construction support frame 10 provides fire protection simultaneously, thereby makes this fire wall body 100 can satisfy the fire prevention requirement of transformer substation.
