Description
Technical field
The invention belongs to construction engineering technical fields, and in particular to a kind of fire prevention connecting structure of steel column assembled finishing.
Background technique
Application has the advantages that high-strength light to steel construction under construction, but needs to do anti-corrosion and flameproof protection.Steel knot at present
The flameproof protection way of structure, there are commonly paste the methods of fire-proof plate, sprayed fire proofing coating.The material for pasting fire-proof plate has expansion
The materials such as vermiculate fireproof plates, air entrained concrete fire-proof plate, fireproof coating have scumbling type fireproof coating and thick-layered fire coating etc..
It is more stringent to the sectional dimension requirement of steel structure member since the use function of house is more special in steel house,
The interior that excessive scantling will affect residential housing uses function.Paste fire-proof plate way due to contoured cross-section it is excessive,
Application in house is restricted.
The way of spraying thick-layered fire coating easily causes cracking and falls off since the intensity of fireproof coating is lower, and
Fireproof coating outer layer painting mortar can not be bonded effectively.In public building, common practices is plug-in in fireproof coating outer layer
Decorative panel, such as stone material, aluminium sheet or ceramic wafer etc., steel structure member compact dimensions are larger, influence on public building little.It is living
In residence, thick-layered fire coating cannot need architectural surface directly as exterior finish, and common thick-layered fire coating is strong
Degree is generally below 2MPa, and outside is needed to have protective layer.The most commonly used is Thistle boards for Indoor Residential Ecological, pass through lightgage steel joist and steel knot
Structure connection, when fire occurs, lightgage steel joist and connector can conduct heat, and reduce the thermal insulation property of fireproof coating.
Country is pushing assembled architecture at present, it is desirable that the way that building is fitted up using assembled.Assembled is fitted up in wall
The way in face is mainly the mode of veneer, after the completion of the vertical members such as wall, column, using fabricated mode make to fit up pipeline,
Finishing material is separated with internal structure.The method of assembled finishing can have preferable combination with the fire prevention of steel construction, but at present
There are problems that the fire prevention of connector and insulation.
Summary of the invention

Root lightgage steel joist, every lightgage steel joist are embedded in fireproof coating along steel column direction arrangement, fire-resistant parts are parallel to and are located at steel
Between column and lightgage steel joist；
Every lightgage steel joist is provided with multiple apertures along steel column direction at equal intervals, and fire-resistant parts, fire prevention portion are equipped at aperture
Fire-proof heat-insulating connector of the part by steel fastener and on steel fastener forms；Lightgage steel joist passes through fire-proof heat-insulating connector
It is connected on steel fastener with self threading pin；
The steel fastener is formed by bending inwards among steel plate, and steel plate bends inwards Formation cross-section as U-shaped bar shaped
Groove, strip groove are parallel to steel column direction, strip groove notch both sides of the edge at the scene before welded (when being prefabricated in the factory)
Be fixed on steel column outer surface, the top of strip groove is provided with a v notch v, the surface of steel fastener and steel column at the scene before pass through
Anti-corrosion treatment；
The fire-proof heat-insulating connector successively by interior cylinder, intermediate cylindrical, three cylinders of outside cylinder are coaxially connected forms, three
The identical through-hole of a size is provided among a cylinder, the diameter of intermediate cylindrical and the U-shaped opening of steel fastener are of same size,
So that intermediate cylindrical is flush-mounted in U-shaped opening, interior cylinder is located in U-type groove and interior body length is less than U-type groove depth, and outside cylinder is remote
One end from steel fastener is in contact with lightgage steel joist, and self threading pin passes through lightgage steel joist and is threadedly coupled to fire-proof heat-insulating connector
Through-hole.
The self threading pin wears three cylinder intermediate throughholes for being installed on fire-proof heat-insulating connector.
Be equipped at the aperture of lightgage steel joist described in every multiple fire-resistant parts and neighbouring two fire-resistant parts it
Between between be separated with multiple apertures, the through-hole that self threading pin passes through in decoration panel, which is connected on lightgage steel joist, does not install the small of fire-resistant parts
Hole, the aperture between lightgage steel joist described in adjacent two is corresponding, and the aperture at sustained height is disposed with anti-along surrounding
Fiery component.
The length of the intermediate cylindrical is greater than the thickness of steel fastener, so that installing when construction laborsaving.
The lightgage steel joist is bent by galvanized steel plain sheet, and section configuration is c-type or U-shaped.
Concrete is perfused with inside the steel column.
The material of the decoration panel is Thistle board, fiber cement board or other Indoor decorative plates.
The anti-corrosion treatment is specifically to coat paint.
The fire-proof heat-insulating connector uses ceramic material.
The beneficial effects of the present invention are:
1) welding procedure of the invention is completed in factory, and no site welding first welds and remakes preservative treatment, will not break
Bad erosion resistant coating.
2) assembled card slot of the invention design, simple installation reduce field erected artificial.
3) present invention is all made of standardized components, and bulk industrial production is at low cost.
4) fireproof heat insulating material that fire-proof heat-insulating connector of the invention uses, realizes in lightgage steel joist and steel fastener
Between thermal insulation, and flameproof effect is good.
