Abstract

Device for the controlled opening and / or closing of an opening (6) in a building (1), in particular in a building envelope, such as in an elevator shaft (2), characterized in that this opening (6) is a slide (8, 8.1) is assigned, which is transverse to the opening (6) movable into the opening cross section.

Description

The present invention relates to a device for the controlled opening and / or closing of an opening in a building, in particular in a building envelope, such as in an elevator shaft.

State of the art

It is known that building areas, in particular those that are located in or on the building envelope, such as elevator shafts and air ducts, in the case of a gas alarm, but especially in a fire, to be kept free of the gas.

According to the current state of the art, it is assumed that both the smoke extraction and the ventilation of the elevator shaft can take place in a natural way. Therefore elevator shafts generally have an opening through which both a ventilation of the shaft and thus the elevator car, as well as in case of fire, a smoke extraction of the shaft by natural ventilation, d. H. purely passive and without active ventilation, should be guaranteed. This opening is generally located in the elevator shaft head or, if present, in an elevator machinery room above it and leads directly to outside the building envelope.

Since elevator shafts often have to be ventilated throughout the day, a cooling down of the property or even an undesirable heat input into the same via the elevator shaft would be unavoidable in such a practice and would in the worst case lead to a collapse of the energy concept of the property.

Only in case of fire, even with such energy concepts, all means, so also the supply of external fresh air into the property, regardless of the temperature of this fresh air, right to ensure the most efficient smoke extraction of the elevator shaft.

The DE 202 016 101 528 U1 describes a system for ventilating and / or de-smoking a, in particular with lying in different elevator levels, separate fire sections of a building associated elevator shaft, which is bounded by vertical shaft walls.

The following components are required for the above-mentioned invention:

• - Fans, which are arranged on opposite sides of the elevator shaft, wherein on each of the sides at least two provided at different vertical positions fan provided and at least the arranged on one of the sides fan with reversible air conveying direction are operable;
• - A supply air duct, which connects the elevator shaft with a lying outside the building outside area and having a first motor-adjustable closure element, with which it is closable;
• - An exhaust air and smoke extraction duct, which connects the elevator shaft with the outside area and has a second motor-adjustable closure element, with which it can be closed;
• A controller connected to the fans and drive motors for motor-adjusting each of the first and second shutter members, the controller for controlling the drive of the fans and the fans operable with reversible air-conveying direction also for controlling the air-conveying direction thereof; is arranged to control the drive motors of the closure elements, and
• At least one sensor connected to the controller, wherein the connection between the at least one sensor and the controller is adapted to provide the controller with sensor signals about the need to ventilate the elevator car and / or the hoistway and / or the need for hoistway smoke extraction and / or or to provide an air exchange of the air in the elevator shaft.

The above invention discloses a system which is very complicated and expensive to implement. In addition, it is costly and rather not applicable for existing buildings.

Object of the invention

The object of the present invention is to provide a simple and cost-effective alternative to the controlled opening and / or closing of an opening in a building, which can also be used in existing buildings.

Solution of the task

To achieve the object, that this opening is associated with a slide, which is movable transversely to the opening into the opening cross section.

The advantage of this is that the slide due to this property has a low construction height, accordingly takes up little space and thus can be used in existing buildings.

The movement of the slide is approximately at right angles to a central axis of the opening and can thus be used to save space in a lift shaft. It is also encompassed by the idea of the invention that the slide is movable obliquely to the central axis. But then it must be designed larger than the opening cross-section.

The slider preferably has an outer circumference which corresponds approximately to the cross section of the opening. When opening the slide thus a very large part of the opening is exposed, which means that the elevator shaft can be ventilated quickly.

The slide is guided on and / or in rails and thus ensures a smooth opening. It should be in the appropriate guides for sealing the slide brush seals.

The rails are part of a frame which is at least partially inserted into the housing opening. The slider acts as an extra component and is also because of this property perfectly suited for use in existing buildings can.

Another feature is that the slider consists of at least three layers, one layer of which is made of a thermoresistant material. This ensures that the elevator shaft is insulated and no cold or hot air gets into the shaft and affects the energy efficiency of the building. Furthermore, the slide can withstand prolonged exposure to fire.

The thermoresistant material includes or preferably consists of mineral wool of calcium silicate, which has a particularly insulating property and meets today's standards of energy regulation.

Furthermore, the thermo-resistant material is covered on both sides with a metal, which also withstands a fire longer and protects the slider from possible wear and makes it durable.

The slide is to be operated by electric motor in the preferred embodiment, so that it is autonomous via a controller and to operate quickly in a possible fire.

It should also be noted that the slide remains in the opening cross section of the opening and is removed from the opening cross-section only when necessary, in particular when addressing a sensor, in particular a smoke or CO2 detector or during maintenance. This also ensures high energy efficiency.

figure description

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings; these show in:

1 a partially illustrated cross section of a hoistway with an inventive device for controlled opening and / or closing of the shaft opening in the operating position;

2 a perspective view of the inventive device according to 1 ;

3 a partially illustrated cross section of an elevator shaft with a further embodiment of an inventive device for the controlled opening and / or closing of the shaft opening.

The 1 shows a building section 1 with a lift shaft 2 and an elevator car 3 which is vertical in the elevator shaft 2 is mobile up and down. Furthermore, it can be seen that at a shaft head 5 of the elevator shaft 2 an elevator mechanic 4 is provided, which will not be explained further in the further course.

In the area of the shaft head 5 of the elevator shaft 2 opens, in the present embodiment, horizontally mounted opening 6 which acts as an exhaust air and smoke extraction duct, the elevator shaft 2 to the outside, to the ambient air outside the building. The opening 6 However, it can also be formed vertically. Over the opening 6 is a dome of light 7 be provided on the daylight in the elevator shaft 2 can come in or serve as snow and rain protection.

The opening 6 is a slider 8th associated, which transverse to the opening 6 is movable into the opening cross section. The movement of the slider 8th takes place approximately at right angles to a central axis 9 the opening 6 and is marked with an arrow a. Thus a movement of the slider 8th is possible, this is on or in rails 10 led, which in 2 will be clarified in more detail.

In 1 becomes the slider 8th shown in the closed state, but the dashed line indicates in which position the slider 8th in the opened state drives.

It should also be noted that the slider 8th has an outer circumference, which is approximately the cross section of the opening 6 equivalent.

In 2 becomes the slider 8th dormant and shown in the open state. The slider 8th is in a frame 13 let in, with the frame 13 rails 10 includes over the the slider 8th can be moved back and forth and so can be moved from an open to a closed state. The slider 8th must be kept as airtight and guided. For this purpose brush seals are provided in the preferred embodiment.

It becomes clear that the slider 8th from at least three layers 11.1 - 11.3 consists of which one layer 11.2 is made of a thermoresistant material, for example mineral wool made of calcium silicate. This results in a heat transfer value (U value) of about 1.2, while the previous values of, for example, smoke flaps are about 10.

The other two layers 11.1 and 11.3 are made in the preferred embodiment of metal and close the insulating layer 11.2 between themselves.

Furthermore, the shows 2 two L-shaped metals used to attach the slider 8th serve. In addition, the slider points 8th a very low construction height, so that it is ideal in already existing extract shafts 2 can be installed.

It should be noted that the slider 8th is intended for the sealing of shafts or skylights, wherein the building envelope is not affected. The slider 8th usually remains in the closed state and is only opened in special cases, for example, during maintenance or when the cabin could collide or for ventilation of the elevator shaft 2 if a corresponding sensor reports CO2 or smoke. Furthermore, the slider should 8th additionally be opened by hand.

The drive of the slider 8th is preferably done via a small electric motor and a chain drive, which will not be explained here.

3 shows a further embodiment of the arrangement of a slider 8.1 , this being in the open state outside the elevator shaft 2 moves and thus the complete cross section of the opening 6 releases, so that, for example, the smoke can pull off even faster.

In addition, it is conceivable that the frame 13 in itself two slides 8th includes, which are opposite openable.
