Description

Labeled door

Technical field

The utility model relates to a kind of protective door of building field, relates in particular to a kind of steel labeled door.

Background technology

Fire resistance steel door is to adopt the high-quality cold-rolled steel sheet, corrosion resistant plate is by cold-formed protective door, mainly be applicable to highrise building or the building of fire protection requirement is arranged, mainly constitute by door leaf and doorframe, door leaf and doorframe are hinged by hinge, light filling refractory thermal insulating material in the door leaf, be provided with seal groove around the doorframe, insert fire proof seal bar in the seal groove, when closing, the subsides of door leaf and doorframe and face are realized sealing by weather strip, play every cigarette, sound insulation, fire-retardant, the effect of disconnected heat, the seal groove of existing various fire resistance steel doors mostly forms by bending or welding steel, as Fig. 1, shown in Figure 2, for installing and fastening needs, seal groove has various cross sectional shape, as " U " type, half " Ω " type etc., but the setting of these seal grooves all has a common defective, to be exactly seal groove as one side of doorframe inboard all fitted by steel plate roll compacting forms for that, the thickness that has only one or two steel plate, cooperate for the line face between doorframe and the door leaf, both are connected, sealing area is little, sometimes even be not closed completely, can produce the saturating cigarette phenomenon of saturating fire, occur danger easily, soundproof effect is also relatively poor, because the inner side edge of seal groove also plays position-limiting action, therefore narrow fitting face can make the bigger impact force of generation between the two in closing closed procedure, make the side of seal groove very easily be out of shape, finally cause seal failure or weather strip to come off, simultaneously owing to the bump of seal groove side door leaf, be easy to cause door leaf to fall lacquer, distortion influences attractive in appearance and functional performance.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of fireproof performance height, labeled door that soundproof effect is good of sealing.

For achieving the above object, the utility model labeled door comprises doorframe, door leaf, hinge and Hardware fitting, doorframe and door leaf are respectively by making after the steel plate roll compacting, doorframe and door leaf are connected through the hinge, the doorframe inboard is stepped, it is provided with the groove that matches with the inboard face of door leaf, is inlaid with the fire proof seal bar in this groove, is provided with the binding face that cooperates with door leaf between the inner side edge of groove and the inner side edge of doorframe.

Further, described doorframe is formed by the steel plate bending, leaves suitable distance between the inner side edge of groove and the inner side edge of doorframe, forms a hollow bulb, and folding surface between the two is the binding face that cooperates with door leaf.

Further, described weather strip cross section roughly is " P " font, is installed in the whole binding face that the interior back of groove covers doorframe and door leaf.

Further, the horizontal interface of described weather strip roughly is " B " font, which is provided with groove, and described groove shapes and weather strip match, and extends in the groove of one side of groove on weather strip, forms an angle of colluding with the weather strip chucking.

Further, the horizontal interface of described weather strip roughly is " L " font, is provided with two grooves that match with the sealing bar in the doorframe, leaves the binding face that matches with door leaf between two grooves.

Further, described groove is two, also is provided with the binding face that matches with door leaf between two grooves.

Further, described groove is three, is equipped with the binding face that matches with door leaf in twos between the groove.

The utility model is provided with the binding face that matches with door leaf in the doorframe inboard, contact cooperation for the face face between doorframe and the door leaf, line face different from the past cooperates, sealing area is big, it is tighter that doorframe and door leaf are fitted, can stop effectively that flue gas passes, improve the fireproof performance of labeled door, sound insulation value also is significantly improved simultaneously.

The specific embodiment

First embodiment as shown in Figure 3, labeled door mainly is made of doorframe 1, door leaf 2, doorframe 1 and door leaf 2 are respectively by riveting after the steel plate roll compacting shaping or being welded, doorframe 1 and door leaf 2 are connected through the hinge, doorframe 1 inboard stepped, it is provided with the groove 3 that matches with door leaf 2 inboard faces, is inlaid with fire proof seal bar 4 in this groove 3, be provided with the binding face 7 that cooperates with door leaf between the inner side edge 5 of groove 3 and the inner side edge 6 of doorframe, groove 3 and binding face 7 form by the steel plate bending.

Second embodiment as shown in Figure 5 leaves suitable distance between the inner side edge 8 of groove and the inner side edge 9 of doorframe, forms a hollow bulb 10, is the binding face 11 that cooperates with door leaf between the two.

As shown in Figure 6, the cross section of weather strip 12 roughly is " P " font, the whole binding face of doorframe and door leaf is all covered after being installed in the groove, has so not only improved overall sealing performance, can also play cushioning effect when doorframe and door leaf collide.

As shown in Figure 7, then be provided with two grooves in the doorframe, be separately installed with weather strip 13 and weather strip 14 in two grooves, two grooves and doorframe inner side edge have formed binding face 15 and the binding face 16 that matches with door leaf, can play the double seal effect, can stop effectively that not only flue gas passes, soundproof effect is also very desirable.

As shown in Figure 8, then be provided with three grooves in the doorframe 17, form three binding faces that match with door leaf altogether.

As shown in Figure 9, the horizontal interface of weather strip 18 roughly is " B " font, which is provided with inwardly recessed groove, and the shape of groove and weather strip 18 match, and extend in groove on one side of groove, forms one and colludes angle 19 with what weather strip tightened.

As shown in figure 10, the horizontal interface of weather strip 20 and weather strip 21 roughly is " L " font, is provided with two grooves that match with weather strip in the doorframe, and two grooves are symmetrical arranged, the slot opening that weather strip 21 wherein is installed forms the binding face 22 that matches with door leaf towards the inboard between two grooves.

Certainly; the utility model is not limited to above-mentioned embodiment; anyone can both draw other various forms of structures under enlightenment of the present invention, be the labeled door that leaves the binding face of certain width in the doorframe inboard in every case, all drops within the protection domain of the present utility model.
