Description

A kind of single open-type has the perspective fire resistant doorsets of skeleton structure

Technical field

The utility model is related to fire resistant doorsets technical field, there is specially a kind of single open-type the perspective of skeleton structure to prevent fires Door.

Background technology

Fire resistant doorsets refer to the door that can meet fire stability, integrality and thermal insulation within a certain period of time and require.It is to set There are the fire protection separators of certain fire resistance in fire protection interval, emergency staircase, vertical shaft etc..Fire resistant doorsets, which remove, to be had commonly Outside the effect of door, 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, really Protect evacuating personnel.

And with the development of heat insulation type flame resistant glass, more and more traditional fire resistant doorsets have begun to replace with fire prevention glass Glass especially in glass-wall building, but in this frame mode, if is improved by flame resistant glass whole The fire resistance property of a system, it is impractical, therefore, under existing technical field, often by flame resistant glass and fire prevention Door is combined, it is made both to have had ability of the ability of fire resistant doorsets but also with flame resistant glass.

But this combination is in the prior art, there is also following defects：The knot of flame resistant glass and fire resistant doorsets It closes, due to will produce joint gap, the decrease of the fire protecting performance of fire resistant doorsets or flame resistant glass can be led to, and due to broken It is broken the overall structure of fire resistant doorsets so that just the fire resistant doorsets rigidity supporting structure of fragility is affected originally so that this combination Fireproof door structure might as well be original in whole fire resistance property any one fire proof construction.

Invention content

In order to overcome the shortcomings of that prior art, the utility model provide a kind of perspective of the single open-type with skeleton structure Fire resistant doorsets improve the structure between joint gap, make it have it is good carve conjunction, and door leaf structure is improved, with branch Support can also have original fire resistance property while acting on, and can effectively solve the problem that the problem of background technology proposes.

Technical solution adopted by the utility model to solve its technical problems is：

A kind of single open-type has the perspective fire resistant doorsets of skeleton structure, including doorframe and door leaf, between the doorframe and door leaf It connects in such a way that hinge hinge for fireproof is in singly to open, and is connected by fireproof door closer with the top of door leaf in doorframe, Heat insulation type flame resistant glass is installed on the door leaf；

The door leaf is equipped with flame-retardant plywood, anti-fire door core board, fire-proof plate and flame-retardant plywood, and institute successively from the bottom to top It states and is equipped with lining framework in anti-fire door core board, the end of the anti-fire door core board is equipped with peripheral frame skeleton.

As a kind of preferred technical solution of the utility model, the door residing for the hinge hinge for fireproof and fire-proof door closer Reinforcement steel plate is equipped on fan.

As a kind of preferred technical solution of the utility model, the doorframe and door leaf, heat insulation type flame resistant glass and door leaf Between be equipped with fireproof expansion seal part.

As a kind of preferred technical solution of the utility model, the heat insulation type flame resistant glass is fixed by glazing bead pacifies On door leaf.

As a kind of preferred technical solution of the utility model, also by being located at door leaf side between the doorframe and door leaf Fireproofing door lock locking connection.

Compared with prior art, the utility model has the beneficial effects that：The utility model is pacified by using glazing bead Heat insulation type flame resistant glass is filled, and fire prevention Expansion sealing is equipped between doorframe and door leaf, heat insulation type flame resistant glass and door leaf Part improves the seal between joint gap, secondly, by improving the structure of door leaf, it is made to have fire prevention and rigid support knot Structure combines both, it is made both to have had the fire performance of flame resistant glass, also has the fire performance of fire resistant doorsets, integrates To improve the practicability of fire resistant doorsets.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

As shown in Figure 1 to Figure 3, the utility model provides a kind of perspective fire resistant doorsets of the single open-type with skeleton structure, packet Doorframe 1 and door leaf 3 are included, is connected in such a way that hinge hinge for fireproof 5 is in singly to open between the doorframe 1 and door leaf 3, and in door The top of frame 1 and door leaf 3 is connected by fireproof door closer 2, is connected doorframe 1 and door leaf 3 by hinge hinge for fireproof 6 Come, and further by the way that fireproof door closer 2 is arranged so that having the ability being automatically closed between doorframe 1 and door leaf 3, in institute It states and heat insulation type flame resistant glass 9 is installed on door leaf 3, the heat insulation type flame resistant glass 9 is fixedly mounted on door by glazing bead 12 On fan 3.

And heat insulation type flame resistant glass 4 includes thick float glass, and a closed sky is formed by several blocks of 5mm float glasses Between, and it is filled with fire resistant fluid in this closed space.
