Abstract
The utility model discloses doorframe section bar. The cross section is generally a square with a gap (4) on one side, three sides of the square respectively include a door inner side (1), a door contacting side (2) and a door outer side (3), a cross fireproof groove (22) is arranged in the door contacting side (2), and the opening direction of the cross fireproof groove (22) is opposite to that of the gap (4). The cross fireproof groove (22) is arranged in the door contacting side (2), the opening direction of the cross fireproof groove (22) is opposite to that of the gap (4), and fireproof material bars are filled in the cross fireproof groove (22). When a fire disaster occurs, the fireproof material bars of the cross fireproof groove (22) horizontally extend after heated and expanded, and a gap between a plugged door leaf and a door frame effectively prevent dense smoke from entering and isolating flame. The cross fireproof groove (22) is horizontally arranged, so that the doorframe section bar is simple in structural design and convenient to machine.
Description
Technical field
The utility model relates to a kind of building door member, particularly a kind of doorframe.
Background technology
Existing doorframe mainly by the door inner side edge, with the door contact edge and outdoors the right angle that forms of side partly enclose framework, be provided with groove with the door contact edge, and in groove, fill fireproof strip or damping sound insulation bar, make door have the function of fire prevention, damping sound insulation thereby support the use with door leaf.But existing doorframe often structure design is comparatively complicated, processing inconvenience, and manufacturing cost height and decorate properties are not good.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of reasonable in design, and is easy to process, the doorframe that Outside decoration is strong, and adopt doorframe that this doorframe makes and door leaf to support the use to have good fireproof performance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: a kind of doorframe, its cross section substantially is one side and has the square of a breach, these three square limits be followed successively by an inner side edge, with door contact edge and side outdoors, with the horizontal fire prevention groove that is provided with opening direction and gap opened opposite direction on the door contact edge.
As further improvement of the utility model, with the orthogonal vertical sound insulation groove of opening direction that offers opening direction and horizontal fire prevention groove on the door contact edge, vertically the sound insulation groove is positioned at a side of horizontal fire prevention groove.By offering the orthogonal vertical sound insulation groove of opening direction of opening direction and horizontal fire prevention groove and filling flexible damping sound insulation bar in this vertical sound insulation groove with the door contact edge, when the metal percussion sound that can reduce at closing time between door leaf and the doorframe, play the effect of damping sound insulation.
As preferred structure of the present utility model, laterally prevent fires groove and vertical sound insulation groove are right angle groove or arc-shaped groove.Adopt right angle groove or arc-shaped groove, conveniently shape.
In order to make doorframe more attractive in appearance, strengthen the ornamental of doorframe, side is undaform curve or circular curve upholstery border outdoors.
The beneficial effects of the utility model: by being provided with the horizontal fire prevention groove of opening direction and gap opened opposite direction with the door contact edge, and in laterally preventing fires groove, this fills the fire proofing wood material strip, when breaking out of fire, laterally horizontal expansion after the fire proofing wood material strip chance thermal expansion of fire prevention groove, slit between shutoff door leaf and the doorframe, effectively prevent entering and isolated flame of dense smoke, fire prevention groove horizontally set, structure design is simple and easy to process.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further;
Fig. 1 is the shape of cross section schematic diagram of the utility model doorframe the first embodiment;
Fig. 2 adopts the doorframe of Fig. 1 doorframe and the shape of cross section schematic diagram of door leaf;
Fig. 3 is the shape of cross section schematic diagram of the utility model doorframe the second embodiment;
Fig. 4 adopts the doorframe of Fig. 3 doorframe and the shape of cross section schematic diagram of door leaf.
The specific embodiment
Fig. 1 to Fig. 4 illustrates a kind of doorframe of the utility model, its cross section substantially is one side and has the square of a breach 4, these three square limits be followed successively by an inner side edge 1, with door contact edge 2 and side 3 outdoors, the horizontal fire prevention groove 22 opposite with breach 4 opening directions with being provided with opening direction on the door contact edge 2.By being provided with the opening direction horizontal fire prevention groove 22 opposite with breach 4 opening directions with door contact edge 2, and laterally filling the fire proofing wood material strip in the fire prevention groove 22, when breaking out of fire, laterally horizontal expansion after the fire proofing wood material strip chance thermal expansion of fire prevention groove 22, slit between shutoff door leaf 5 and the doorframe, effectively prevent entering and isolated flame of dense smoke, fire prevention groove horizontally set, structure design is simple and easy to process.
As further improvement of the utility model, with the orthogonal vertical sound insulation groove 21 of opening direction that offers opening direction and horizontal fire prevention groove 22 on the door contact edge 2, vertically sound insulation groove 21 is positioned at a side of horizontal fire prevention groove 22.By offering opening direction with door contact edge 2 and the orthogonal vertical sound insulation groove 21 of opening direction of the groove 22 of laterally preventing fires and filling flexible damping sound insulation bar in vertical sound insulation groove 21, when the metal percussion sound that can reduce at closing time between door leaf 5 and the doorframe, play the effect of damping sound insulation.
For shaping easy to process, laterally prevent fires groove 22 and vertical sound insulation groove 21 are right angle groove or arc-shaped groove.
In order to make doorframe more attractive in appearance, strengthen the ornamental of doorframe, side 3 is undaform curve or circular curve upholstery border outdoors.
Above-mentioned doorframe preferentially adopts stainless steel or aluminum alloy materials to make, and it is also passable certainly to adopt other hard materials to make.
Fig. 1 and Fig. 2 are the first embodiment of utility model doorframe, and this doorframe being inserted in wall 6 is used with outward opening door leaf 5, consists of the door of external-open mode.Fig. 3 and Fig. 4 are the second embodiment of the utility model doorframe, and this doorframe being inserted in wall 6 is used with inner-opening type door leaf 5, the door of evolution formula in consisting of.
The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, can also under the prerequisite that does not break away from the utility model aim, make various variations.
