SK6610Y1 - Door opening between rooms - Google Patents

Abstract

Door opening between rooms, equipped on the wall (1) with door casing (2) of door (3) consisting of lining and casings, where between the lining and / or casing and the wall is formed at least one ventilation duct (4) connecting rooms.

Description

Technical field

The technical solution relates to a two opening between the rooms, equipped on the wall with a lining door frame consisting of lining and lining.

BACKGROUND OF THE INVENTION

In the interior of buildings, door frames in the door are used to pass through the apertures, and if a ventilation function is required, the ventilation grille is fitted in the two wings, placed in the door area and disrupting their design, or ventilated by leaving a larger gap. between the floor and the bottom edge of the door, which looks unesthetic, the light passes through here and the noise attenuation of the closure is substantially reduced.

The essence of the technical solution

To a large extent, these two drawbacks are eliminated by a two-hole opening between the rooms, provided on the wall with a double doorframe consisting of lining and lining according to the present invention. Its essence is that at least one ventilation duct is created between the lining, the lining and the wall, connecting the rooms.

The channel is preferably wrapped around the wall. The channel may be provided with a filter element. If necessary, a fire-fighting foam is placed in the channel. The inlet openings of the channel can be equipped with a grid or mesh.

Since the ventilation duct is located between the lining, the lining and the wall, it does not affect the door surface or the wall itself. The channel preferably follows the shape of the wall, so no drilling, punching, masonry and similar additional work is required. Since the channel is kinked and its inlet openings are located under or in the panel, light from the adjacent room does not penetrate through the channel.

If the duct is equipped with a filter element, minimal swirl of dust is ensured. Possible grilles at the inlets can form an aesthetic element and prevent unwanted blockages of these openings. If necessary, it is possible to place in the duct a fire-fighting foaming material, which in case of fire ensures that the fire resistance of the whole door and door frame - closure is maintained.

The proposed solution is also effective in terms of price, the possibility of fitting into standardized construction openings, speed of application, durability, faultlessness.

Thus, the casing frame is designed so that when installed in the building opening, ventilation ducts are created which allow free passage of air between the rooms. The channel cross-section is selectable according to the volume air flow requirement. The channel is designed in such a way that it does not allow direct passage of light and only minimally reduces the noise attenuation of the shutter. When the filter cloth is placed, it also permits filtration of the passing air stream. If the fire resistance of the door - door plus door frame - is required, it is possible to equip the ventilation duct with a foam fire-retardant so that it is sealed in case of fire and the fire resistance of the door is maintained. The double leaf remains unchanged, there is no requirement for its dimensional adjustment, such as undercutting to create a gap from the floor.

BRIEF DESCRIPTION OF THE DRAWINGS

The two opening between the rooms according to the present invention will be described in more detail with reference to a specific embodiment with reference to the accompanying drawing, in which: FIG. 1 schematically shown in plan view in section of a wall with a doorframe and a ventilation duct.

EXAMPLES

In the example of a two-room opening, provided on the wall 1 with a door lining 2 of door 3 consisting of lining, threshold, lintel and lining, two ventilation ducts 4 connecting the rooms are formed on each side of the door 3 at the bottom of the door 3. The channels 4 are wrapped around the wall 1 with the inlets and outlets under the lining or in the lining. The outlets may be provided with a grid and the channels 4 may be provided with filter elements.

In the channels 4, a fire-fighting foaming material 5 can be placed.
