Abstract
A steel fire-resistant door frame comprises a steel door frame. A clearance is left between a fire blocking surface and a fire banking surface which are arranged on the steel door frame and abutted on a door leaf, and the fire blocking surface and the fire banking surface are connected with a bent section extending inwards. A flame-retardant and heat-insulating material is filled at the bent section inside the door frame. The utility model has the advantages of simple structure, convenient production, low cost, good fire resistant effect and long service life.
Description
Technical field
The utility model relates to door and window for building, and particularly the fire resistance steel door frame is made the field.
Background technology
Existing fireproof door frame adopts flame retardant solution to soak processing usually, and its manufacturing process will be passed through immersion → drying, generally needs about 2 months, exist the processing place big, long in time limit, because the soaking depth of timber is limited, can only handle wood surface, fire retardant effect is relatively poor.
Chinese patent literature CN2846687Y discloses a kind of " wooden fire prevention doorframe ".Its wooden door frame table face is compounded with PLASTIC LAMINATED, forms integral structure.Have tooling device requirement height, processing and forming is than complicated problems.Chinese patent literature has disclosed " a kind of fireproof door frame " (CN2702030Y), and it is to be inlaid into fire proofing material in a side rail material of L type timber, and fire proofing material and L type timber body adopt screw or bonding adhesive to be fixed.It has is convenient to processing, and the work period is short, advantage of simple structure.All there is the relatively poor defective of flame retardant effect in above-mentioned two kinds of structures.
Problem and defective that existing common steel fire prevention, antitheft frame exist: can not stop heat to be delivered to the fiery face of the back of the body by the counter-fire face effectively, it is very fast, higher to cause the fiery face of the back of the body to heat up, and can not satisfy the relevant technologies index request of the Ministry of Public Security to this type of fire product.
The utility model content
The purpose of this utility model provides a kind of fire resistance steel door frame of simple in structure, fire-proof and thermal-insulation good flame retardation effect.
This novel purpose is achieved in that a kind of fire resistance steel door frame, comprises steel doorframe, on the steel doorframe with the stifled fiery face of door leaf adjacency with bank up a fire gapped and be connected by a bending segment that extends internally between the two between the face.
Be filled with the anti-flaming thermal-insulation material on this bending segment position in the doorframe, or do not fill the anti-flaming thermal-insulation material.
The bending segment that extends internally on the above-mentioned steel doorframe is a rectangle bending segment or for the triangle bending segment or be circular bending segment and other any random geometry of not disconnecting.
This is novel by set up the fire-proof and thermal-insulation zone in doorframe, and (on the bending segment position formation fire-proof and thermal-insulation hole) fills the anti-flaming thermal-insulation material in this zone, or do not fill the anti-flaming thermal-insulation material and fill other any materials, and cooperation fireproofing glue strip, on the one hand, prolong the transmission of the bang path and the obstruction heat of heat, on the other hand, after fire resistance steel door frame, fan are subjected to fire, the gap is filled by the fireproofing glue strip later that expands between frame, the fan, stop the fiery face transmission of supporting or opposing of flame, heat, make entire product reach fire prevention steel doorframe correlation technique index.
Compared with prior art, this novel have simple in structure, easy to process, cost is low, the characteristics of flameproof effect better (fireproof performance was above 3 hours), long service life.
Description of drawings
Fig. 1 is this novel cross-section structure (door leaf close situation);
Fig. 2 is the structure chart that door leaf shown in Figure 1 is opened situation.
The specific embodiment
Fig. 1 Fig. 2 illustrates, this novel steel doorframe 1 that comprises, with the stifled fiery face 1c of door leaf 2 adjacency with bank up a fire gappedly and be connected by a bending segment that extends internally between the two between the face 1d, be filled with anti-flaming thermal-insulation material 4 (also bending segment can be coated) on this bending segment position in the doorframe on the steel doorframe 1.The bending segment that extends internally on the steel doorframe 1 is rectangle bending segment 1e, or is triangle bending segment or for circular bending segment or for other any possible geometry.The stifled fiery face 1c of steel doorframe 1 is provided with fireproofing glue strip 3.Among Fig. 2, counter-fire face 1a and the fiery face 1b of the back of the body are arranged on the steel doorframe 1, side elevation 2a and external surface 2b are arranged on the door leaf 2, door leaf 2 is connected with steel doorframe 1 through fire prevention hinge 5.
Embodiment:
Stifled fiery face 1c and the door crack of banking up a fire between the face 1d are 5mm, and counter-fire face 1a width is 68mm, and carrying on the back fiery face width degree is 35mm, and the thickness of door leaf is 50mm.
Claims (4)
1, a kind of fire resistance steel door frame comprises steel doorframe (1), it is characterized in that: described steel doorframe (1) go up with the stifled fiery face (1c) of door leaf (2) adjacency and the face of banking up a fire (1d) between gapped and be connected by a bending segment that extends internally between the two.
2, according to the described fire resistance steel door frame of claim 1, it is characterized in that: the bending segment that extends internally on the described steel doorframe (1) is a rectangle bending segment (1e) or for the triangle bending segment or for circular bending segment.
3, according to the described fire resistance steel door frame of claim 2, it is characterized in that: the stifled fiery face (1c) of described steel doorframe (1) is provided with fireproofing glue strip (3).
4, according to claim 1 or 2 or 3 described fire resistance steel door frames, it is characterized in that: be filled with anti-flaming thermal-insulation material (4) on this bending segment position in the described doorframe.
