Sliding doors automatic: specifications and photos

Modern office buildings, large shopping centers, stations and airports - such public places with a large flow of people can no longer be imagined without automatic sliding doors. This design greatly simplifies the entrance and exit from the building to people with a suitcase, basket or stroller. Doors open when approaching them and close after a set interval of time.

The choice of automatic doors is due to their undeniable convenience, as well as a long service life and safety. The only obstacle to their installation is the lack of space to open the doors.

If there was a question of a choice - to establish a simple door or sliding entrance doors automatic - it is better to weigh all the pluses of the second design:

• They have increased throughput;
• The entrance to the building becomes more comfortable;
• The work intensity includes millions of opening cycles;
• Maintaining a constant temperature by reducing heat loss;
• Increased safety due to the presence of special sensors;
• Increase the status of the organization.

The opening options for automatic doors are only three: swinging, sliding and rotating.

Swinging machines

This is the most economical solution. Special drive is installed on any existing door. The lever mechanism allows the door to close tightly.

Sliding option

The system of automatic sliding doors is the most popular solution. The opening can not exceed three meters, but the height is not limited. Sliding doors have different variations: they can be radial, telescopic, angled, semi-circular, folding and equipped with an anti-panic system.

Rotating

These doors are called revolving, or revolving. They are designed for a very large flow of visitors. These doors are the only ones that support the microclimate of the room, without interfering with the free passage of people. No dirt, no cold or noise from the street will not penetrate the building when installing such a system. These doors are not only reliable, but also durable: their resource is designed for 15-20 years of continuous operation.

Materials

Most often for automatic doors use two proven and reliable materials:

• Stalinite. It is a tempered glass, which in the upper layer has a modified crystal lattice, obtained by melting. This is done for safety. When breaking such a glass, the fragments will have rounded edges, which will reduce the risk of cuts.
• Triplex. With the help of polymeric compounds, several layers of glass are connected. Upon impact, such a structure will not break down into small pieces, since most of them remain stuck together.

Types of sliding doors

Installation of sliding automatic doors is determined by the project, depending on the conditions of the finished doorway.

In most cases, this is an individual order. The most popular are four types of automatic doors:

• Standard . At the same time, the valves usually leave in opposite directions. The block itself contains horizontal guides for movement.
• Semicircular . This option may interest your unusual design. Very stylish look such doors, while the interior can be selected for any design idea - all thanks to the smooth curve of the guides and canvases.
• Corner . It will become an original solution when choosing the design of both the facade of the building and the internal filling. The angle between the flaps can be straight or any other size.
• Telescopic . Sliding doors are automatic this option involves the presence of several doors in the passage. At the same time, they completely cover the space in the closed state, and in the open one go behind one another. Such doors are installed when there is no additional space for installing other, more massive cloths.

Specifications:

• The opening speed of the 2 sliding doors is about 1.5 m / s;
• The maximum total weight of the sliding door leaves is 200-260 kg;
• The resource of the geared motor - at least 3 million openings;
• The thickness of the leaves is about 10 mm;
• The response speed of the sensor is less than 1 second., While it is located at a height of 2 to 7 meters.

Elements of a design of an automatic door

There are three main door elements with automatic opening:

• Directly webs that can be made of a different material.
• Guides and rollers, which constitute the mechanism of the sliding system.
• The electric drive, which has electronic control and is equipped with additional accessories.

Fabrics are made of a triplex or stalinite, the frame for them can be steel or aluminum.

Automatic sliding glass doors are often transparent. Sometimes they can have drawings, engraving, dullness.

Sliding automatic aluminum doors have a different profile thickness, depending on the weight of the leaf. To seal the opening into the ends of the canvas, special seals of rubber and brushes are installed.

The mechanism for opening the automatic door is located in the upper part of it. This is due to the fact that the installation from below because of a large influx of visitors will soon become unusable. Installed automatic sliding doors, the instruction to which is provided by the manufacturer, only by professionals in this field. Otherwise, there is a risk of incorrect installation, which will shorten the life of the product.

Components of automatics

Sliding doors automatic have several basic elements in electronics accessories:

• Sensor (or detector) of motion. Its function is to open door leaves when a person appears in a certain zone, and then close the canvas if the object is missing in the system visibility for a given time. Modern sensors do not react to weather phenomena (precipitation or light), and are performed by infrared or microwave.

• Photocell. This device allows a person to be safe even in the doorway, the cloths do not close.
• Accumulators of trouble-free operation. Sliding doors automatic will be able to continue working even when the main power is disconnected. But the running time is limited by the battery charge.
• A selector that allows you to set different modes. Sometimes it is equipped with software.
• Locks electromechanical type. They allow you to block doors when the building is closed at night or on a non-working day.

Types of opening

Depending on the way of opening the door, automatic type doors are divided into:

• Sliding . In this design, the flaps simply move along the guides. It should be noted that such a door does not hold much heat.
• Parallel sliding . Such a system is considered the most successful, although it has a threshold, but it is quite high and does not reduce the heat-shielding qualities of the door. Cloths go along the guides in the usual mode, and for ventilating the room the sash can be thrown away.
• Sliding and sliding . Sliding doors automatic of this design imply the presence of a fixed part, into which the movable leaf leaves. In this case, the threshold of the door serves as a disadvantage, which degrades the heat-shielding properties and, at low temperatures, is subject to icing.

Modes of operation

Automatic doors are equipped with a special device - selector, which allows you to select the required opening mode. There are five modes of operation:

1. Unilateral. In this case, the door works only in one direction - to the entrance or exit.
2. Standard. Movement occurs when the object is approached from any direction.
3. Summer. Cloths work in normal mode and diverge completely.
4. Winter. The movement of the canvas occurs to a certain limit, that is, not to the end.
5. Closed. The sensors do not work at the approach of the object, the canopies open only from the signal of a special electronic key, which is usually at the guard.

Programs allow you to configure the opening of doors in the specified mode.

Their function is to determine the distance at which the person should be to trigger the opening sensor. You can also set the speed of the motion of the canvas.

Advantages of an automatic sliding door

• Greater throughput with limited time.
• Noiselessness.
• Resistance to drafts. Canvases will not swing in the gusts of the wind.
• The advantage over swinging structures is in saving space in front of the door by moving the canvas to the edges of the opening.
• Setting up the necessary modes for a different stream of customers and different seasons.
• Wide choice of design.
• There are almost no restrictions on the size of the future design.

Disadvantages of an automatic sliding door

There are two significant reasons why automatic doors are not installed:

• high price;
• The need for preventive work, which also requires additional costs.

But these disadvantages apply only to the installation in a private room, in which it will not be difficult to pull or push the door. In rooms with a large flow of visitors, such shortcomings will not become an obstacle to installation: positive properties compensate for all the shortcomings.
