Abstract

The utility model relates to a four-prevention safety door which can prevent sound, heat, fire and theft. The utility model is composed of a door leave, a doorframe and a door lock, wherein, the door leaf is composed of an inner and an outer panels, and a door leaf framework; the door leave framework is a grating-typed reinforcing rib checker cavity which is formed by connecting wood section material and steel section material in cross vertically and horizontally, and the inner part of the cavity is filled with fireproof heat-insulating material. The doorframe is assembled and welded by adopting that a thin steel plate is pressed into the abnormity section material, a rubber sealing strip is inlaid in a rabbet flute in the doorframe, and the door leave are connected with the doorframe through a hinge. The utility model has the advantages of simple structure, light weight, low cost, good seal performance, good heat insulation performance, good anti-theft performance and high safety. Thereby, the utility model can be used widely for civil buildings and public buildings.

Description

Four anti-safety doors

The utility model relates to a kind of four anti-safety doors of sound-insulating fire-proof and theft-proof.

The outer door of the resident family of building or one-storey house is most is at present made by wood materials, and sealing, insulation, fire prevention, theftproof performance are all poor.Generally for antitheft, install a steel security door again additional in the outside of wooden door, such two opening directions are opposite, and it is big to take up space, and the people comes in and goes out or load grade inconvenience, has increased engineering cost simultaneously, has wasted wide variety of materials.

The purpose of this utility model is that a kind of light firm, easy to use, four anti-safety doors with sound insulation, insulation, fire prevention, theftproof performance will be provided.

The purpose of this utility model is achieved in that a kind of four anti-safety doors are by door leaf, doorframe and door lock constitute, door leaf is made up of interior outer panels (3) and door leaf skeleton, door leaf skeleton intersects assembling in length and breadth by the wooden profile material of flame treatment and steel section bar and connects into fence rinforcement bar grid chamber, fill flame-proof thermal insulation material in the grid chamber, doorframe is pressed into the profile shapes assembling by steel sheet and is welded into, the doorframe seam is pressed with groove, setting-in sound insulating seal bar in the groove, door leaf skeleton and hinge Bolt Connection, an end liner that penetrates door leaf skeleton has joint cover, on the door Three-bearing safe-guard door lock is housed, thereby this door has reached sound insulation, insulation, fire prevention, antitheft purpose.

The utility model is simple in structure, adopt wooden and steel section bar to be combined into paling form rinforcement bar door leaf, under the intensity that guarantees door, alleviated the weight of door, one side of hinge-coupled door leaf is lined with joint cover, guaranteed linking intensity, setting-in weather strip in the doorframe seam groove, the door leaf inner chamber is filled with flame-proof thermal insulation material, on the door Three-bearing safe-guard door lock is housed, thereby this door is in light weight, cost is low, sound insulaton, insulation, fire prevention, theftproof performance are good, safe and reliable, can extensively on civilian and public building, use.

Below in conjunction with drawings and Examples the utility model is illustrated in detail.

Fig. 1 is the utility model structural representation;

Fig. 2 is A among Fig. 1-A sectional view;

Fig. 3 is door leaf skeleton of the present utility model and hinge-coupled schematic diagram.

Among the figure: 1, door leaf; 2, doorframe 3, panel; 4, door leaf skeleton; 5, grid chamber; 6, flame-proof thermal insulation material; 7, groove 8, weather strip 9, hinge; 10, bolt; 11, joint cover; 12, door lock.

Shown in Fig. 1-2, a kind of four anti-safety doors, it is made of door leaf (1), doorframe (2) and door lock (12), it is characterized in that door leaf (1) is made up of interior outer panels (3) and door leaf skeleton (4), door leaf skeleton (4) by wooden and steel profile shapes in length and breadth interconnection be assembled into paling form rinforcement bar grid chamber (5), play the shock resistance reinforcement effect, prevent that the people from piercing indoorly for breaking door leaf (1), wooden profile material is through flame treatment.Load onto panel (3) in the inside and outside both sides of door leaf skeleton (4), panel (3) is for being sprayed with the five-ply board or the three-ply board of ornamental or fireproof paint, fill flame-proof thermal insulation material (6) between the interior outer panels (3) in grid chamber (5), heat insulating material (6) adopts rock wool and aluminosilicate refractory fiber, plays fire prevention, insulation, deadening.Doorframe (2) adopts the steel sheet of 1.5 millimeters thick to be pressed into profile shapes assembling welding by certain geometrical shape, doorframe (2) seam is pressed with groove (7), the interior setting-in weather strip of groove (7) (8), weather strip (8) adopts foam rubber material, plays sound insulation, insulation effect.As shown in Figure 3, door leaf skeleton (4) connects with bolt (10) with high strength hinge (9), and an end liner that penetrates door leaf skeleton (4) has joint cover (11), twists admittedly with nut then, prevents that bolt (10) is loosening, guarantees to connect fastness.Adopt the lengthening screw attachment between hinge and the doorframe (2), on the door Three-bearing safe-guard door lock (12) is housed, the deformed steel pellet shot from a slingshot is housed in the lock core, anti-drilling, pick-proof, double cylinder lock size of key reaches 60,000 times, has strengthened anti-theft effect.
