Description
A DOOR HOLE INSERT FOR FIRE ISOLATION TECHNICAL FIELD The present disclosure relates to a door hole insert, a fire isolating door comprising a door hole insert and a method for manufacturing a door hole insert. BACKGROUND ART Buildings are conventionally equipped with doors of different types. Generally, it is desirable that doors in buildings have some form of isolation against fire to protect both structural parts (of building and door as such) and humans.
Since existing doors in buildings are of different types, the degree to which they are able to withstand fire differs between the doors. Common parts of a door that is vulnerable to fire are the door holes, for example the door handle holes. |fthe door handle holes of any door is strengthened against fire, it will to some degree provide an improvement to the fire-resistance of the door as a whole.
However, improving the fire resistance ofthe door by strengthening the door holes usually requires expensive and extensive modification of a door, which creates reluctance for users to do such modification. |nstead a user may buy a more fire-proof door which in turn also is expensive.
Based on the above, there is a need for means that provide improvement of the fire resistance in doors in general and existing doors in particular. More specifically, there is need for a door hole insert for improving the fire isolation of doors, where such an insert is, price-convenient, easy to install in new and existing doors while providing for increased fire isolation for doors.
Even though some currently known solutions work well in some situations it would be desirable to provide a door hole insert that fulfils requirements related to price-convenience and handling efficiency i.e. being easy/convenient to install into new and existing doors.
SUMMARY lt is therefore an object of the present disclosure to provide a door hole insert, a door comprising a door hole insert and a method for manufacturing a door hole insert to mitigate, alleviate or eliminate one or more ofthe deficiencies and disadvantages of currently known solutions.
This object is achieved by means of a door hole insert, a door comprising a door hole insert and a method for manufacturing a door hole insert as defined in the appended claims.
The present disclosure relates to a door hole insert for isolation against fire comprising a hollow metal cylinder, a collar extending radially outwards from a top surface of said hollow metal cylinder and a swelling material attached to an inner surface area of said hollow metal cylinder. Further, the door hole insert is arranged for manual insertion into a door hole, wherein when said door hole insert is inserted in a door hole, an inner surface of said collar is arranged to be in contact with an outer door surface. ln other words, when said door hole insert is in an inserted state, an inner surface of said collar is arranged to be in contact with an |H outer door surface. lt should be noted that the term "meta also encompasses steel. Thus, the hollow metal cylinder may be a hollow steel cylinder.
An advantage of the door hole of the present disclosure is that it allows for a cheap and reliable insert which can improve the isolation ofthe door against fire. Moreover, it is manually insertable and compatible with doors of different types and sizes. ln case of a fire, the swelling material will swell/expand towards a center ofthe cylinder preventing heat to spread into the inner parts of the door and to damage the door parts as such. I\/|oreover, since the swelling material is attached to the inner circular surface of the insert, it will provide a joint swelling against the center which in turn leads to a higher density of swelling material within the cylinder, thus the properties ofthe swelling material are optimized by attaching it to the inner surface in a manner as in the present disclosure. Thereby providing a sealing function against heat so to insulate the door against heat in a reliable manner. lt should be noted that a door hole may refer to a door handle hole or a door lock cylinder hole.
