Description
Technical field
The present invention is relevant for a kind of fire prevention zoning system of structure, is meant especially a kind ofly can effectively completely cut off the fire prevention zoning system that burning things which may cause a fire disaster is toppled over to prevent structure.
Background technology
Along with metropolitan area population constantly increase and the land resources condition of limited under, the development of the building orientation skyscraper of metropolitan area is real be the trend of certainty.At present the structure of skyscraper adopts the reinforcing bar structure more, and its main cause is that the reinforcing bar structure has advantages such as in light weight, that the construction period is short and construction quality is good, therefore is more suitable for structure as skyscraper than steel concrete.
See also shown in Figure 1A, the 1B, be the structure schematic diagram of existing skyscraper.This structure 1 comprises a plurality of reinforcing bar structure floors 11, each reinforcing bar structure floor 11 all comprises members such as a plurality of steel columns 112, girder steel 114 and floor 116, for example wherein utilize full infiltration weldering mode to dock between steel column 112a and the steel column 112b, girder steel 114 is incorporated into the side surface of steel column 112b, and floor 116 is arranged on the girder steel 114.
Because the shortcoming of reinforcing bar structure maximum is thermo-labile, and existing structure body 1 all is that steel column 112a is directly combined with steel column 112b in design, steel column 112b is directly combined with girder steel 114, in case building breaking out of fire, the high temperature of thousands of degree will cause the reinforcing bar structure softening, in addition, the thermal conductivity of reinforcing bar material is good, the temperature of high heat will be promptly from the fire nidus to around conduction, when the steel column 112 of structure 1 begins to soften, add the weight of steel column 112 top buildings, steel column 112 just probably causes collapsing of building moment because frustrate in the wrong.
With the U.S.'s 911 incidents is example, the Gemini building is the skyscraper of a reinforcing bar structure, after it is attacked, the temperature of high heat promptly from the blast floor to around conduction, high temperature makes steel column become softening, the weight of adding building itself causes frustrating of steel column in the wrong, causes whole building just to collapse soon after being attacked.
Because the loss of collapsing for life and property of building is millions of, and fire or blast can cause the most important reason of collapsing of skyscraper to be the poor heat resistance of reinforcing bar structure, therefore, fire and blast etc. are unexpected to be taken place if people can't avoid, also should do suitable fire prevention zoning at the structure of skyscraper, the thermal source that fire is produced be controlled at the specific region can't to around conduction, avoiding causing collapsing of whole building, and then reach the effect of control infringement.
Summary of the invention
Main purpose of the present invention is to provide a kind of fire prevention zoning system of structure, and the design by this fire prevention zoning system makes structure when breaking out of fire, and thermal source can be controlled in the specific region, to avoid causing collapsing of structure.
In order to achieve the above object, the fire prevention zoning system of structure provided by the present invention comprises at least:
One first fire district, comprise at least one reinforcing bar structure floor, this reinforcing bar structure floor has a plurality of first steel columns and a plurality of first girder steel, and wherein above-mentioned first steel column is the box post that the center is provided with opening, and above-mentioned first girder steel is incorporated into the side surface of first steel column;
One floor, be arranged in the opening of first girder steel top of this first fire district and above-mentioned first steel column, this floor comprises a steel corrugated plate and a refractory material, and this steel corrugated plate combines with this first girder steel, and this refractory material is filled in the opening of this steel corrugated plate surface and this first steel column;
One second fire district, comprise at least one reinforcing bar structure floor, this reinforcing bar structure floor has a plurality of second steel columns and a plurality of second girder steel, the bottom of wherein above-mentioned second steel column is equipped with a board and a column, this board is incorporated into this slab surfaces, and this column is imbedded in the opening of this first steel column.
In the present invention, utilize a plurality of crab-bolts to combine between this board and this floor.
In the present invention, this column surface is provided with a plurality of WELDING STUDS, in order to strengthen column and to be filled in bond stress between the refractory material in the opening.
In the present invention, this refractory material is a fiber steel reinforcing concrete.
In the present invention, this refractory material is a calcium silicates.
In the present invention, this refractory material is asbestos.
As shown in the above description, effect of the present invention is significant: fire prevention zoning of the present invention system is distinguished into a plurality of fire districts with structure, for example steel column does not have directly and combines between first fire district and second fire district, but by in addition combination of the floor between two fire districts, because this floor comprises refractory material, when a fire district breaking out of fire or an explosion time wherein, the high temperature that it produced will be controlled among this fire district and can't to around conduction, therefore, fire prevention zoning of the present invention system can avoid comprehensive the collapsing of structure, and then reduces the loss of life and property.
