Abstract

The utility model relates to an air-tight sound insulated door, comprising a door leaf and a doorframe. The door leaf is composed of two steel decks and an inner filled layer made of honeycomb paper. The periphery of the doorframe is provided with hollow stamping steel ribbons made of soft and flexible SPVC materials. The periphery of the door leaf is provided with end face members which abut with the stamping steel ribbons. No gaps are provided between the door leaf and the doorframe for obstructing air currents and the sound insulation.

Description

Airtight soundproof door

Technical field

The utility model relates to a kind of door with deadening, particularly airtight soundproof door.

Background technology

Under some occasion, people are higher to the sound isolation requirement in room, thereby need take soundproof measures, as adopt partition wall that sound insulation materials makes, soundproof door, soundproof window etc., but still be difficult to the effect that reaches satisfied sometimes, main cause is that the slit is arranged between general door leaf and the doorframe unavoidably, and adjacent room or the outdoor various sounds or air-flow can be invaded from the slit.

Summary of the invention

The purpose of this utility model provides a kind of airtight soundproof door, and it has good airtight and soundproof effect, intercepts adjacent room or extraneous air-flow or sound.

This airtight soundproof door comprises door leaf and doorframe, and door leaf is made up of two steel plate layers and middle honeycomb paper internal layer of filling; Around the doorframe hollow seal bar that soft toughness material is made is housed, SPVC macromolecular material weather strip for example, each limit can offset with the sealing bar and seal around the door leaf; Also can install the end face member additional around door leaf, offseting by member and sealing bar seals; When door leaf cut out, the end face member nose around the door leaf was tight against the soft sealing strip of doorframe, and closely contact is seamless to make the two.Said doorframe can be combined by aluminium alloy element, but this member contains the groove of fixing seal bar.

This airtight soundproof door is under the situation of biparting clamshell doors, and one in the clamshell doors is provided with the limit, vertical aluminium alloy door that contains groove, weather strip is housed in the groove; Another door leaf offsets with end face member and sealing bar.

In sum, be tight against with the rigid door limit soft sealing strip of door leaf between the door leaf of this airtight soundproof door and the doorframe and cooperate, under the door leaf closed condition, the door limit of rigidity or raised line are to soft toughness and hollow weather strip direction extruding, thereby the two is closely offseted, eliminate the slit between door leaf and the doorframe, thereby intercepted air-flow intrusion outdoors, reached airtight effect; In addition, the honeycomb paper internal layer of door leaf internal layer and SPVC hollow seal bar all have good deadening, thereby have reached obstruct sound and air-flow effect.

Description of drawings

Fig. 1 (1), Fig. 1 (2) are the cross sectional representation of two embodiment of this airtight soundproof door.

Fig. 2 is the embodiment longitudinal cross-section schematic diagram of this airtight soundproof door.

Fig. 3 (1), Fig. 3 (2) are the airtight sound-insulating structure embodiment schematic diagrames between two that split.

Fig. 1 (1), Fig. 1 (2) represent the cross sectional representation of this airtight soundproof door closed condition, and as shown in the figure, door leaf 1 is made up of two steel plate layer 1-1 and the middle honeycomb paper internal layer 1-2 that fills; Left-hand door frame 2-1 and right doorframe 2-2 are equipped with the hollow seal bar 3 that the SPVC material is made, and door leaf 1 left and right sides installs end face member 11 additional, and offseting by member 11 and sealing bar 3 seals; Doorframe 2-1 and 2-2 are formed by steel steel door frame unit construction, and contain flutedly in the member inboard, and weather strip 3 is fixed in the groove.Doorframe is a hollow body, can mortar concrete 4 in it.Among the figure, the 5th, reinforcing steel bar, with the doorframe field Welding, the 6th, concrete, brick wall, the 7th, the stainless steel hinge of door leaf 1, the 8th, dead bolt.

Among Fig. 1 (2), the end face member 11 of door leaf 1 protrudes to weather strip 3 directions, the end face member of its left and right, upper and lower four sides all with nose 9 be tight against the doorframe inboard weather strip 3, only represented the sealing state of nose 9 and left-hand door frame 2-1 and right doorframe 2-2 among Fig. 1 (1), Fig. 1 (2).

Fig. 2 represents the longitudinal cross-section of this air tight door soundproof door, and in this example, door leaf 1 contains a glass 12, and end face member 11 all is equipped with in the both sides up and down of door leaf; 2-3 is a upper door frame among the figure, and 2-4 is a lower door frame of making the threshold shape, and upper and lower doorframe all contains fluted, and SPVC weather strip 3 is housed in the groove, and the upper and lower end face structure 11 and the weather strip 3 of door leaf 1 offset.

Fig. 3 (1) expression door leaf be two 1 of bipartings and 1 ', door leaf 1 ' be provided with vertical the limit 10 that contains groove is equipped with weather strip 3 in the groove, another door leaf 1 offsets with end face member 11 and sealing bar.

Fig. 3 (2) expression biparting door leaf 1 ' be provided with contains fluted vertical limit 10, and weather strip 3 is housed in the groove, and another door leaf 1 offsets with rigidity raised line member 12 and sealing bar.
