Description

Smoke-proof sound-proof sealing piece

Technical Field

The utility model relates to a smoke protection sound insulation sealing member.

Background

According to the existing door, an anti-collision strip is usually additionally arranged between a door leaf and a door frame to reduce the collision of the door leaf and enhance the sealing property between the door leaf and the door frame. The crashproof strip sets up the positive one side of just to the door leaf in the limit groove of door frame usually, and mostly is the protruding form of arc type, can carry out the block to the door leaf of frontal impact. However, such an anti-collision strip only blocks one side of the door leaf, and the arc-shaped convex sealing effect is not good.

SUMMERY OF THE UTILITY MODEL

For improving the leakproofness of current anticollision strip, the utility model provides a smoke protection sound insulation sealing member can wrap up sealedly to the door leaf edge, realizes the sealed syllable-dividing effect of anticollision, and the fire door is used in the cooperation, can prevent indoor cigarette of wading by the flue gas of temporary separation conflagration before the fire prevention sealing strip inflation.

The utility model provides a smoke control sound insulation sealing member, the fixed strake of first fixed strake and second including mutually perpendicular connects is equipped with the elastic sealing strake of buckling inwards respectively in the edge of the fixed strake of this first fixed strake and second, and two elastic sealing strakes are relative and have the interval.

As a further improvement, the width of the first fixing edge strip is the same as the width of the second fixing edge strip, and the degree of the included angle of the elastic sealing edge strip is the same as the degree of the included angle of the first fixing edge strip or the second fixing edge strip.

As a further improvement of the present invention, the included angle between the elastic sealing edge and the first fixing edge strip or the second fixing edge strip is 35 to 45 °.

As a further improvement of the present invention, the elastic sealing edge is gradually thinned from the side of the first fixing edge strip or the second fixing edge strip connected to the elastic sealing edge.

As a further improvement, the outside of the first fixing edge strip and the second fixing edge strip is a smooth bonding surface.

As a further improvement of the utility model, the fixed strake of first fixed strake, second is integrated into one piece with the elastic sealing limit.

As a further improvement of the utility model, the fixed strake of first fixed strake and second is the stereoplasm plastic, the elasticity sealed edge is the elasticity plastic.

The utility model has the advantages that:

the utility model discloses during the use, install the turning limit position department at the limit groove of door frame and door leaf cooperation stop, first fixed strake and the fixed strake of second be mutually perpendicular connect with the laminating of the right-angled turning limit position of limit groove fixed, the process of closing the door, the front and the side of door leaf receive the cushioning effect on elastic sealing limit, prevent acutely to strike the damage door leaf. And under the state of closing the door, the crossing edge position of the front of door leaf and side falls into the space that fixed strake and elastic sealing limit surrounded, and elastic sealing limit offsets with the front and the side of door leaf respectively, be equivalent to the corner of hugging closely the door leaf, sealed effect is good, can effectively completely cut off indoor outer sound, and the use of preventing fire door cooperation can stop the conflagration temporarily and produce the toxic flue gas leakage and enter the room at the fire prevention sealing strip inflation in-process of preventing fire door, improves the smoke protection effect of preventing fire door, safe and reliable.

Detailed Description

The application scheme is further described below with reference to the accompanying drawings:

referring to fig. 1-3, a smoke-proof and sound-proof sealing member comprises a first fixing edge strip 1 and a second fixing edge strip 2 which are vertically connected with each other, wherein an inwardly bent elastic sealing edge strip 3 is respectively arranged at the edges of the first fixing edge strip 1 and the second fixing edge strip 2, and the two elastic sealing edge strips 3 are opposite and have a distance. And the elastic sealing edge 3 is gradually thinned from one side of the connected first fixing edge strip 1 or second fixing edge strip 2.

The width of first fixed strake 1 and the fixed strake 2 of second is the same, is 12mm, the length of elastic sealing edge 3 beginning to its tail end by first fixed strake 1 or the fixed strake 2 one side of second that connect is 6 mm. The included angle a between the elastic sealing edge 3 and the first fixing edge strip 1 or the second fixing edge strip 2 is the same and is 45 degrees.

The outside of first fixed strake 1 and the fixed strake 2 of second is smooth binding face, and during the installation, this binding face is fixed with door frame 4 bonding.

The first fixing edge strip 1, the second fixing edge strip 2 and the elastic sealing edge 3 are integrally formed. The first fixing edge strip 1 and the second fixing edge strip 2 are made of hard plastic, preferably hard PVC; the elastic sealing edge 3 is elastic plastic, preferably soft PVC.

During installation, the smoke-proof and sound-proof sealing element is installed at the corner edge position of the edge groove where the door frame 4 and the door leaf 5 are matched and stopped, specifically, the edge groove 41 of the door frame 4 comprises a stopping surface for stopping the front surface of the door leaf 5 and a limiting surface which is perpendicular to the stopping surface and matched with and used for limiting the side surface of the door leaf 5. The smoke-proof and sound-proof sealing piece is arranged at the position where the stop surface and the limiting surface are vertically crossed, and the first fixing edge strip 1 and the second fixing edge strip 2 are respectively bonded and fixed with the stop surface and the limiting surface.

In the door closing process, the front surface and the side surface of the door leaf 5 are buffered by the elastic sealing edge 3, so that the door leaf 5 is prevented from being damaged by violent impact. And under the state of closing the door, the crossing edge position of the front and the side of the door leaf 5 falls into the space surrounded by the first fixed edge strip 1, the second fixed edge 2 and the elastic sealing edge 3, and the elastic sealing edge 3 respectively offsets with the front and the side of the door leaf 5, which is equivalent to tightly holding the corner of the door leaf 5, achieving excellent sealing effect and effectively isolating indoor and outdoor sound. The smoke-proof sound-proof sealing piece can prevent collision and has good sound-proof effect when being used daily; use in cooperation with the fireproof door can temporarily block the fire from generating toxic smoke to leak into the room in the expansion process of the fireproof sealing strip of the fireproof door, so that the smoke prevention effect of the fireproof door is improved, and the fireproof door is safe and reliable.

The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
