Abstract
A kind of Novel fire-proof door, belongs to labeled door technical field.The utility model comprises doorframe, door leaf, Fire-proof lock, labeled door handle, hinge for fireproof, fire-proof door closer, and described doorframe arranges the first fire safe seal at itself and described door leaf junction; Described door leaf arranges the second fire safe seal at itself and described doorframe junction; When door leaf closes, described first fire safe seal coordinates with described second fire safe seal the inclusion structure being formed and be mutually close to.The utility model structure is simple, and by improving doorframe and door leaf sealing, prevent crack between a door and its frame from meeting high temperature deformation, effect of heat insulation is better, effectively stops that fire spreading, flue gas spread.
Description
Technical field
The utility model relates to labeled door technical field, particularly relates to a kind of Novel fire-proof door.
Background technology
Labeled door is the important component part of structural fire protection measure, and in building, fire escape all needs to arrange labeled door in fire compartmentation place.Labeled door all can deform in processing, installation, use, heat more will be out of shape, these factors often make gap between door leaf and door leaf diminish and normally can not open closedown labeled door, and gap between door leaf from door leaf also can be made to become large and different effective prevention fire spreading, flue gas diffusion.
Utility model content
For overcoming problems of the prior art, the utility model provides a kind of not yielding, Novel fire-proof door that fire proof seal is good.
The utility model provides a kind of Novel fire-proof door, comprises doorframe, door leaf, Fire-proof lock, labeled door handle, hinge for fireproof, fire-proof door closer, and described doorframe arranges the first fire safe seal at itself and described door leaf junction; Described door leaf arranges the second fire safe seal at itself and described doorframe junction; When door leaf closes, described first fire safe seal coordinates with described second fire safe seal the inclusion structure being formed and be mutually close to.
This Novel fire-proof door utilizes two groups of seals to coordinate the sealing realized between doorframe and door leaf, is applicable to single open-door or double door.When door leaf closes and uses at ordinary times, door leaf is connected with doorframe opposing seal; When a fire, along with temperature raises, the space between doorframe and door leaf diminishes gradually, not yielding between door leaf and doorframe, effectively intercepts fire spreading, flue gas diffusion.
As preferably of the present utility model, described first fire safe seal and described second fire safe seal are curling shape weather strip.
As preferably of the present utility model, the curl direction of described first fire safe seal is contrary with the curl direction of described second fire safe seal.
As preferably of the present utility model, the curling number of plies of described first fire safe seal or the curling number of plies of described second fire safe seal three layers at the most.
As preferably of the present utility model, the curling number of plies of described first fire safe seal is identical with the curling number of plies of described second fire safe seal.
As preferably of the present utility model, described first fire safe seal and described second fire safe seal are respectively the reeded sealing ring of tool and have protruding sealing ring.
As preferably of the present utility model, the number of recesses that described first fire safe seal has is identical with the protruding quantity that described second fire safe seal has.
As preferably of the present utility model, described first fire safe seal and described second fire safe seal top layer be coated with anticorrosion, put moth coating.
The utility model has following beneficial effect:
The utility model Novel fireproof door is simple, and by improving doorframe and door leaf sealing, prevent crack between a door and its frame from meeting high temperature deformation, effect of heat insulation is better, effectively stops that fire spreading, flue gas spread.

Detailed description of the invention
As Fig. 1, the utility model Novel fire-proof door comprise doorframe 1, door leaf 2, Fire-proof lock 3, labeled door 4, hinge for fireproof 5 and fire-proof door closer 6.Described door leaf 2 realizes sealing by two-layer fire safe seal with described doorframe 1.In order to prevent doorframe 1 and door leaf 2 gap because of high temperature deformation, described doorframe 1 is provided with the first fire safe seal 7 at itself and described door leaf 2 junction, and described door leaf 2 is provided with the second fire safe seal 8 at itself and described doorframe 1 junction.Described first fire safe seal 7 can be expanding sealing strips with described second fire safe seal 8, when door leaf closes, first fire safe seal 7 and the second fire safe seal 8 are by high-temperature expansion, and two fire safe seal cooperatively interact and the gap between doorframe 1 and door leaf 2 is effectively closed up.
As Fig. 2, as preferably, described first fire safe seal 7 is curling shape weather strip with described second fire safe seal 8, at general temperature, when door leaf 2 is opened, the naturally curling gathering of the first fire safe seal in doorframe 1, as the limit groove of doorframe 1, the naturally curling gathering of second fire safe seal in door leaf 2, the limit groove of door leaf 2.When door leaf 2 closes, the mutual inclusion of two curling shape weather strips, once temperature raises, weather strip expanded by heating, the inclusion structure of two weather strips is tightr, and sealing performance is stronger.When two curling shape weather strip curl directions are contrary, the mutual inclusion of two curling shape weather strips is curling, effective sealing doorframe 1 and door leaf 2.The curling number of plies of above-mentioned curling shape weather strip is too many, is not easy to two curling shape weather strip inclusions, even causes door leaf and the closed difficulty of doorframe, arranges the curved weather strip of three-layer coil at the most.When two curling shape weather strip numbers of plies are identical, can tight inclusion, after high-temperature expansion, door leaf and doorframe good airproof performance.
In addition, also can consider that arranging described first fire safe seal 7 is the reeded sealing ring of tool, and the second fire safe seal 8 is for having protruding sealing ring (not shown).Relative to the weather strip of curling shape, when door leaf closes, coordinate not tight.When fire occurs, temperature raises, and sealing ring expands, and respective bump and fit depressions, realize door leaf and doorframe seals, and stops flue gas diffusion.It is identical with protruding quantity that described groove can be set, realizes effective sealing and coordinate.
Because of fire be expection less than accident, need to consider the durability of seal, described first fire safe seal and described second fire safe seal top layer scribble anticorrosion, mothproof coating.
When a fire, escape personnel firmly can pin labeled door by Fire-proof lock 4.Because of fire proof seal double-deck between door leaf 2 and doorframe.When fire spreading, fire safe seal raises with temperature and expands, and two fire safe seal 7,8 interact, and coordinates and forms effective sealing, prevent fire spreading, intercepts smog, protection escape personnel safe escape.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
