Abstract
The utility model relates to an aluminium-steel composite anti-theft fire-retardant door frame which is composed of an aluminum alloy outer frame, a steel plate inner frame, a reinforcement connecting plate and sealing strips. The overlapping position of the aluminum alloy outer frame and a door leaf is provided with grooves parallel with doorframe edges. Rubber sealing strips or fire-resistant expanding rubber sealing strips are arranged in the grooves. The utility model can overcome the defects of easy rusting and poor decorative effect of a steel plate door frame, and can also overcome the defect of insufficient strength of an aluminium alloy door frame. The anti-theft fire-retardant door made of the door frame has the performances of theft protection, fire prevention, sealing and sound insulation, and has good decorative effect.
Description
The utility model relates to antitheft, labeled door, the anti-theft and fireproof door doorframe that particularly a kind of aluminum steel is compound.
In prior art, mostly metal anti-theft, fireproof door frame are to adopt the steel plate bending to form.This steel door frame, though intensity is good,, getting rusty easily, decorative effect is poor.Can not adapt to people to the more and more higher requirement of building finishing.Though the labeled door that has adopts aluminium alloys to make doorframe, its intensity is too low, does not reach desirable anti-theft effect.
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of anti-theft fireproof effective, and compound antitheft, the fireproof door frame of the aluminum steel of outward appearance U.S..
Technical solution of the present utility model is: be made up of aluminium alloys housing, steel plate inside casing, reinforced company's fishplate bar and weather strip.In the aluminium alloys housing, be provided with the steel plate inside casing,, be provided with the groove parallel, rubber weather strip or back-fire relief combustion expanded rubber weather strip is installed in the groove with the doorframe rib in the lap-joint of housing and door leaf.
The cross sectional shape of the utility model doorframe can be single rabbet or two rabbet.The cross sectional shape of lap-joint's groove of housing and door leaf is the shapes of two inboards, below with a word wing, can also be the shape of the anti-hook of dovetail groove or two inboard band right angles, below.
The cross sectional shape of weather strip of the present utility model is the mouth shape or the U-shaped of top two outside band wings, or two outsides are with the U-shaped of the anti-hook of 1 word.
Above-mentioned housing is provided with several rectangular holes parallel with the doorframe rib with the inner edge of the groove of the lap-joint of door leaf.
Above-mentioned inside casing is monolithic or combined type, and monolithic steel plate inside casing is provided with several rectangular holes parallel with the doorframe rib; Combined type steel plate inside casing does not wait the wide troughing plate of leg to combine by two, connects with some junction plates at the wide leg place of two troughing plates.
The utility model has the advantages that: 1. adopt aluminium alloys to do housing, have non-corrosive, good decorating effect, the characteristics of overall appearance U.S..2. be processed into various grooves easily, be convenient to the installation of weather strip.3. the steel plate inside casing had both play and had strengthened antitheft effect, can weld or rivet the connector of hinge seat board, bonnet lock hole stiffener and lintel and munnion again thereon, was convenient to splice doorframe.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is the schematic cross-section of single rabbeted doorjamb of the present utility model;
Fig. 2 is the partial schematic diagram of Fig. 1;
Fig. 3 is another enforcement illustration of Fig. 2;
Fig. 4 is another enforcement illustration of Fig. 2;
Fig. 5 is the another kind of schematic cross-section (two rabbet) of Fig. 1;
Fig. 6 be Fig. 1 A to the rotation schematic diagram.
Each parts shown in Fig. 1-6 are: aluminium alloys housing 1, steel plate inside casing 2, securing member 3, reinforced company's fishplate bar 4, door leaf 5, weather strip are 6.
Embodiment: this doorframe is made up of aluminium alloys housing 1, steel plate inside casing 2, reinforced company's fishplate bar 4 and weather strip 6, make the doorframe outter frame profile with aluminium alloys, the steel plate inside casing 2 of flute profile is set in aluminium alloys housing 1, with securing member 3 aluminium alloys housing 1, steel plate inside casing 2 and reinforced company's fishplate bar 4 are fastened as one, on reinforced company's fishplate bar, circular hole is set, is used for being connected with building.
In the lap-joint of aluminium alloys housing and door leaf, be provided with the groove parallel with the doorframe rib, rubber weather strip or fire-retardant expanded rubber weather strip are installed in this groove.When being used for labeled door, at inner edge making and settlement several slots parallel with the doorframe rib of groove, to reduce heat transfer area, the steel plate inside casing is made monolithic or combined type.On monolithic steel plate inside casing, make several rectangular holes parallel, the heat transfer area in the time of can reducing doorframe like this and be subjected to fire and be convenient in doorframe, pour into packing material with the doorframe rib.Combined type steel plate inside casing does not wait the wide troughing plate of leg to combine by two, at the wide leg place of two troughing plates, connects with some junction plates, reaches the effect of monolithic steel plate inside casing equally.
