Description

Fire doors and their frames

field of invention

The present invention relates to fire doors, particularly - but not exclusively - fire doors suitable for decorative use, especially in apartment buildings, commercial buildings and offices. The invention also relates to a frame for said fire door that can be applied to walls of different thicknesses.

Background technique

Almost every country, especially in developed countries, has required standards for fire doors. There is even an International Standard (ISO). There is also the Cyclic Motion Endurance Test (CMET) for fire doors.

In some countries domestic doors, especially those used in apartment buildings, commercial buildings and offices, are required under certain circumstances to have a minimum fire rating. For example, the fire rating requires the door to be able to resist the advance of a flame for half an hour, or 2 or 4 hours. The door can be made of any material and usually has a metal frame. The door itself is essentially made of solid material such as metal and/or hardwood. Usually a non-flammable material is used for the center, these materials can be vermiculite without chemical treatment, calcium silicate, MDF, cardboard and so on. These materials are hardly decorative, and standard regulations do not allow, for example, glazing on such doors. Thus, while this type of door serves its purpose, it is not a good choice in the environment mentioned above. Many decorative components are not used in fire doors due to their heat transfer properties.

It is therefore an essential object of the present invention to provide a fire door which has a decorative element and is able to fulfill the required functions, having the level of decoration normally required in a domestic environment. Another further object is to provide a frame for said fire door which can be adjusted according to the thickness of the wall.

Contents of the invention

Based on the above objectives, the present invention provides a decorative fire door leaf comprising a central panel including a peripheral leaf frame having two spaced and substantially parallel vertical rails and two spaced and substantially parallel horizontal tracks; the peripheral door frame is made of solid material; the central panel in the peripheral door frame is made of laminated layers of planar material, said layers being held together by a fire-resistant adhesive; The central panel contains at least one decorative feature. The flat material can be plywood.

In another form, the present invention provides a fire rated door comprising a peripheral leaf frame having two separate substantially parallel vertical tracks and two separate substantially parallel horizontal tracks; The outer door leaf frame is made of solid material; the central panel in the outer door leaf frame is made of laminated layers of flat material held together by a fire-resistant adhesive.

The solid material may be hardwood, most preferably 5 or 6 of several layers. The fireproofing adhesive can be sodium silicate or cynshir 26 E5.

The at least one decorative feature may be selected from the group consisting of brass studs, brass laminations, brass strips, plastic layers, kick panels, vision panels, push panels ( push plate, security eye viewer, tiles, timber mouldings, sequencer plates, and security wrought iron-grilles.

The vision panel may have a frame mounted on the inner horizontal rails and the inner vertical rails to hold a pane of glass in relative position. Preferably, the glass sheet is Georgian style wired glass.

The lower track of one of the horizontal tracks may have a groove extending along the length of the lower track, with a floor seal positioned between the grooves for providing a seal between the lower track and the floor.

The door leaf in a set of door device can be a movable door leaf, and can also include a passive door leaf. There may be engaging stiles between passive and trap door leaves.

In yet another form, the invention provides a door frame having a first portion and a second portion, the first portion and the second portion having an overlapping region, the second portion being slidable relative to the first portion in the overlapping region, This allows the door frame to be used on walls of different thicknesses; at least one of the first and second parts has a doorstop.

The first part may comprise a doorstop having a slot therein for slidably receiving an end of the second part therein. Alternatively, the second part has an inner end that cooperates with the first part to form a doorstop.

Detailed Description of Preferred Embodiments

Referring to Figures 1-3, there is shown a door system comprising a passive door leaf (10) and a movable door leaf (12) mounted within a door frame (14) secured to a wall (16). Normally, the door frame (14) has side frames (17, 17a) and door frame rails (19), and also includes a door stop (18) simultaneously. The door leaves (10, 12) are hingedly secured to the door frame (14). If desired, the door frame (14) may include sound and/or noise and/or smoke or fire sealing. The preferred depth range of the door stop (18) is 15-25mm.

The passive door leaf (10) is hingedly connected to the side frame (17) by hinges (20) vertically aligned and secured to both the door frame rail (19) and the door leaf (10). The door leaf (10) is fixed relative to the door frame (14) so that it is only opened when required. For example, it is generally only opened when moving furniture. The movable door leaf (12) is connected in rotation to the door frame side frame (17a) by a second hinge (22), which is fixed to both the door frame rail (19) and the movable door leaf (12) in a conventional manner. superior. The passive door leaf (10) and the movable door leaf (12) may be provided with a door closer (24) in conventional construction and operation. A gate sequencer (26) may also be provided in a conventional manner. The door leaf (10, 12) can be provided with a suitable type of locking device (28), such as a mortise lock with a handle-type door handle and/or a cylindrical lock with a spherical door handle knob, depending on the relevant requirements of the user. and needs to be determined.

Each door leaf (10, 12) has a peripheral door leaf frame, which is preferably made of hardwood material. The peripheral door leaf frames have vertical door edges (20, 32, 34, and 36). The vertical door edges (32, 34) have smoke seals (38) so that when the door leaves (10, 12) are closed a secure closure is produced and a suitable seal is activated when desired or required off. The door leaves (10, 12) each include horizontal upper rails (40) and lower rails (42), which may be of suitable hardwood. The passive door leaf (10) includes a central horizontal track (41, 43). Suitable hardwoods for door edges (30, 32, 34, 36) and tracks (40, 41, 42, 43, and 68) range in density from 575 to 625 kg/m ³ . The best material is "Nyatoh" hardwood. Mounted on the peripheral door leaf frames are central panels (44, 46). As shown, each panel (44, 46) has a number of decorative elements on it. The decorative elements shown and described below are not limited and may be any one or combination thereof, or possible variations of any combination may be used.

Each panel (44, 46) is preferably laminated from several plies of plywood. Preferably, there are 5 or 6 ply plywood. The panels (44, 46) may be of any desired thickness, say 23mm. To secure the plywood panels together, preferably a fire-resistant adhesive is used. An example of such a fire retardant adhesive is sodium silicate or cynshir26 E5. Each panel (44, 46) sits in a groove (86) that sits in a corresponding door lip/track (30, 32, 34, 36, 40, 41, 42, 43, 64) and has a fire seal ( 88) is preferably located in a groove (86). Not all layers have to be plywood. Some may be strandboard, hardwood, cardboard, asbestos cement, MDF (medium density fiberboard), or other materials. The layers can be a mix of the above, for example one outer layer could be plywood and hardwood or MDF (medium density fibreboard) and the middle layer could be cardboard and/or stranded board and/or plywood and/or MDF and/or or asbestos cement. Preferably, for appearance purposes, the outer layers (those layers visible to the user) are typically hardwood or plywood. Panels can be used for other purposes, for example: for interior walls, partitions, removable partitions, screens, movable walls, folding doors, etc.

Some decorations used may include:

1. Brass button (48);

2. Brass sheets (50) or sheets made of other decorative materials are connected to one or two panels (44, 46) by nails, screws or adhesives;

3. Brass strip (52), which can also be made of other suitable substances, such as plastic substances, contrasting wood (contrasting wood) and the like;

4. A plastic layer (54) secured to the panels (44, 46) by means of nails, screws and/or adhesive;

5. The kick plate (56) can be a suitable material, such as stainless steel, which is connected by nails, screws and/or adhesive;

6. The viewing panel (58) may be "Georgia" wired safety glass of suitable thickness, say 6mm, mounted inside the door frame (60), secured by screws 62 to the interior vertical rails (64) and horizontal rails (41, 43) on. The glass can be oval or round, or any other desired shape;

7. Safety peephole (66);

8. The push plate (68) can be made of any suitable material, such as stainless steel or brass, which is fixed by nails, screws and/or adhesives;

9. The tiles (70) are held in place by adhesive, which may be surrounded by a timber molding (72), which may be held in place by glue or nails;

10. The wooden mold (74) is located at the center of the panel (46), which can be connected by adhesive, nails (preferably wooden nails) or screws;

11. Safety wrought iron decorative grille, which can be installed by screws;

The trap door leaf (12) can have a chain door safety lock (76) if desired.

In addition, there may be an elongated groove in the lowermost portion of the track (42) in which there is a seal (80) to prevent smoke, fire or noise from rising/falling. The seal is used to seal with the level track (42) while providing a seal with the floor (78). In this way, the flap (12) can be opened and closed on the floor (78) together with the seal (80) without hindering or restricting its opening and closing movement.

The vertical door edge (36) may be provided with a plastic cover (82) on which may be provided a suitable leaflet or slip of paper detailing the fire rating of the fire doors (10, 12) and other required regulatory documents. Similar covers may be located at similar locations on the side frames (17a).

In Fig. 4, 8 variations of the door frame (16) are shown, in the first 7 (from A to G), the door frame (16) has a first part (84) and a second part (86). Side frames (17, 17a) are mounted or integrated on the first part (84). A slot extends the length of the door frame (14) in which the second portion (86) is movably seated. The slot 88 has a depth relative to the side frame (17, 17a), and the first portion (84) protrudes beyond the side frame (17, 17a). In this manner, the second part (86) can slideably move relative to the first part (84), assuming the inner end (90) of the second part (86) is located in the slot (88), the door frame (14) will can be used. Thus, the maximum extent to which the thickness of the wall 16 varies is the maximum depth of the slot (88). The only difference in form from A to G is the shape of the door frame (14), which is irrelevant to the invention.

In the last form shown in Figure 4, the first portion (84) extends through a solid portion of the wall (16). The second portion (86) extends over the first portion (84) to provide a larger overlapping area. Although there is no specific door stop (18), the extension of the second portion (86) over the first portion (84) actually creates a door stop (18) by means of the step (92).

In this way, a door frame can be used regardless of the thickness of the wall (16) (within certain limits). This provides a considerable margin during installation and drastically reduces the total amount of door frames the builder needs to maintain, thus greatly reducing overhead. Damage to door frames can also be reduced during construction/repair. This also allows greater flexibility in the design and allows the door to be properly aligned. If desired, the door frame (14) can use an adjustable door seal to improve operability. The concurrent progress of the construction crew/contractor will not be hindered by the installation of the door frame.

Although a preferred embodiment of the present invention has been described above, those skilled in the art should understand that various changes and modifications can be made in the detailed design and installation process without departing from the spirit of the present invention.

The invention is not limited to the specific illustrations in the description, but is intended to extend to all possible combinations and modifications of the disclosed and described features.
