Description
Technical field
The invention belongs to door window device technical fields, and in particular to a kind of staircase fire resistant doorsets on-off structure.
Background technique
The application of attention with people to fire, fire resistant doorsets has also obtained very big concern.Fire resistant doorsets generally refer to
The door that fire stability, integrality and thermal insulation require is able to satisfy in certain time.It is usually to be located at fire protection interval, evacuation
Staircase, vertical shaft etc. have the place of the fire protection separators of certain fire resistance.Fire resistant doorsets in addition to having the function of common door,
It has the function of preventing fire spreading and flue gas diffusion, the sprawling of the intensity of a fire can be prevented within a certain period of time, it is ensured that evacuating personnel.
Fire, which occurs, threatens the security of the lives and property of people greatly, and fire preventing is everyone due consciousness.At present
Fire resistant doorsets utilize made by iron material mostly, and apply paint in surface and decorate within doors with cooperating, but such practice occurs in fire
When, pigment can generate chemical gas and be harmful to the human body, and iron material thermal conductivity itself is good, therefore when fire occurs, fire resistant doorsets meeting
It very scalds, makes one directly to open, it is necessary to it looks for other articles and opens indirectly, waste escape time, meanwhile, fire resistant doorsets
It is also possible to damage because of high temperature, causes its flameproof effect poor.Furthermore structure is complicated for some fire resistant doorsets, instruction was not carried out
Experienced people can not open in a great rush or operation error comes to harm.Fire occurs often in life, and stair are to escape safely
Raw main thoroughfare is particularly important in staircase setting fire resistant doorsets, but can generally be occupied very in staircase setting fire resistant doorsets
Big space is unfavorable for the daily routines of people.
In order to solve the shortcomings of the prior art, people have carried out long-term exploration, propose miscellaneous solution
Scheme.For example, Chinese patent literature discloses a kind of fire resistant doorsets [201721038708.1], including doorframe and fire-proof door leaf, prevent
Vent fan is mainly made of anti-fire door core board, and it is U-shaped U-shaped frame that a section is additionally provided between fire-proof door leaf and doorframe, U-shaped
The opening of frame is towards fire-proof door leaf, the opening width of U-shaped frame and the equivalent width of fire-proof door leaf, when U-shaped frame is fixed on doorframe
When, fire-proof door leaf is stuck in the U-type groove of U-shaped frame.
It is poor that above scheme solves fire resistant doorsets fire resistance property to a certain extent, fire resistant doorsets problem easy to damage, but the party
Case still remains many deficiencies, for example, due to the composition of its U-shaped mounting structure, the operation of fire resistant doorsets simultaneously not flexible, fire resistant doorsets
Smoke prevention effect it is general, and the space occupied is slightly larger.
Summary of the invention
Regarding the issue above, the present invention provides a kind of design is rationally, easy flexibly rapid, fire-proof smoke-proof is manipulated
Effect is good, and bearing capacity is big, and can expand the staircase fire resistant doorsets on-off structure of floor space.
In order to achieve the above objectives, present invention employs following technical proposals: this staircase fire resistant doorsets on-off structure, including sets

One hinged cylinder 13, it is hinged that 11 lower end side of door body is equipped with several second shifted to install one by one with the first hinged cylinder 13 respectively
Cylinder 14, an articulated shaft 8 sequentially pass through the first hinged cylinder 13 and the second hinged cylinder 14.Articulated shaft 8 makes closed plate 4 of preventing fires
It is stronger with the connection of door body 11, reduce the probability that fire prevention closed plate 4 falls off under door.
Specifically, fire prevention closed plate 4 includes fire prevention top plate 42 and fire-proof board 43 arranged in parallel, top plate 42 of preventing fires
Be equipped with honeycomb core 44 between fire-proof board 43, and honeycomb core 44 weeks be equipped with to the periphery respectively with top plate 42 and the fire-proof board of preventing fires
43 are connected and are used to install the frame body 45 of the first hinged cylinder 13.Fire prevention top plate 42 and 43 double action of fire-proof board, it is maximum
Change ground accomplish and fire screen from.
Further, honeycomb core 44 includes several arranged in parallel and in continuous trapezoidal with wave crest 46 and trough 47
The waveform strip 48 of waveform, and sheet metal 49 is equipped between two neighboring waveform strip 48, and be located in two neighboring waveform strip 48
The trough 47 of the waveform strip 48 of top and the one-to-one correspondence of wave crest 46 of underlying waveform strip 48 and equal and 49 phase of sheet metal
Even.The wave crest 46 and trough 47 of waveform strip 48 are in flat, the waveform strip 48 being located above in two neighboring waveform strip 48
The trough 47 of wave crest 46 and underlying waveform strip 48 is mutually spliced to form regular hexagon structure, and sheet metal 49 is by positive six
Side shape structure is divided into two parts, and using honeycomb core 44 and its support construction, the structure of honeycomb core 44 makes the carrying of closed plate 4 of preventing fires
Power is big, can prop up the weight of human body, so that indoor space is expanded.
Preferably, fire prevention top plate 42 is arranged close to 11 side of door body, and fire-proof board 43 is arranged close to 21 side of platform, and
The features such as fire prevention top plate 42 and fire-proof board 43 are the slim fire-proof plate of ALC, generate, do not crack without poison gas using ALC fire-proof plate
Accomplish fire safety.
The principle of the present embodiment is: for press block 6 in being connected in installation groove 5 with press seat 7, press seat 7 passes through positioning
Structure 71 is connected with fire prevention closed plate 4, and closed plate 4 of preventing fires and door body lower end are hinged and connected.When there is fire to shut, seat is pressed
7 can start to move, and detachable articulated structure 12 opens, and fire prevention closed plate 4 is with the speed of service of door or press seat 7 and in vertical tight
State after sticker door and circumferential whereaboutss of tiling, fire prevention closed plate 4 are placed in stairs port closing, using preventing fires, 4 material of closed plate is resistance to
The features such as fire and honeycomb core 44 it is heat-insulated accomplish and fire screen from；When the intensity of a fire become smaller or disappear push the door open when, with press seat 7
It resets and the closure of detachable articulated structure 12, fire prevention closed plate 4 can be circumferentially erected in behind the door.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
