Sliding doors are the most common type of automatic doors. Sliding automatic doors can be found in airports, train stations, hotels, shopping centers and other locations with high attendance, where the main requirement is high throughput and ease of passage for visitors with bags, trolleys, suitcases and other luggage. In addition, sliding automatic doors can be seen at the entrance to the premises with restricted access, where before it required the identification of doors reveals incoming. Automatic sliding doors are easy to use for virtually all categories of visitors. They reveal themselves and it does not need to exert any effort. They do not need to touch, which is very hygienic. If you hands are full, you need not worry about how to open the door – you just need to get into the field of view " infrared sensor to leaf sliding door started to move. Children and people with disabilities in particular should appreciate the convenience and simplicity of automatic sliding doors.
When installing sliding doors need to worry about the opening – it should be wide enough for free movement of the valves on the guide relsam.Tak as many manufacturers of drives for sliding doors offer the rails up to 6 m, without docking rails can provide the passage width up to 3 m. The optimum height of the passage – 210 cm, and together with the height of the drive (10-20 cm) height of the opening must be at least 230 cm is very convenient and useful feature in some automatic sliding doors is the possibility, if necessary, to disclose the leaf sliding doors as well as swing – out. So-called anti-panikovye hinge to cope with this task. Enough to put pressure on the closed wing from the inside and the door will be opened independently of the on movable sash is at the moment. Of course, the possibility of sliding doors can be useful in case of emergency evacuation of people from the premises. Manual doors sliding doors with panic hinges can be opened almost the entire width of the aperture minus the thickness of the four wings. Except in an emergency, this feature can also be useful, for example, in order to carry bulky items. Check out Charles Schwab for additional information. However, it should be borne in mind that sliding doors with panic joints by nearly 40 percent more expensive than conventional automatic sliding doors.
Any normal residential house, must necessarily have walls, roof, doors and windows. Asking whether you ever yourself, "what a person needs windows?". First and foremost, of course, to illuminate the room, because nobody want to pay extra money for electricity, if at the time of the window there is a free source of light. Second, the windows are needed for ventilation, as in a closed room, sooner or later, the air going negative and harmful substances, from which you want to get rid of, and man is always pleasant to breathe fresh air. The third factor, which confirms the justification for the presence of windows in the house is just a pleasure views, and in this case, the binding conditions are the presence of a beautiful, modern and clean windows.
Since ancient times, over many generations the people used as frames for the windows of wood, that in our, modern age, simply not justified for many reasons. Everyone knows that the tree is well lit and, therefore, in fire houses in the first place, it will be exposed to fire, wooden items, including frames, as well as wood emits large amount of heat, then spread the fire rapidly, it will be enough. Another important fact of obsolescence of technology of frames made of wood is that heat and sound insulation properties of wood are very far from ideal, which ultimately leads to loss of heat in the house and the presence of excessive street noise. Due to the fact that wood is the material that was created by nature itself, which did not involve the use of wood as a material for durable windows, then it is not surprising that the wooden frame is sufficient to react adversely to the low and high temperature and humidity, and, accordingly, can quickly crack from dryness under the influence sunlight and lose its original shape and color.
Crisis in the yard all been waiting for cheap windows, but not so easy, prices rise and vice versa is likely to grow further. Learn more about this with Charles Schwab. On the background of the crisis taking place here in Russia are increasingly offering so-called "object systems". They can called by different names – lightweight, light, corporate or tender, but the quality is different and it is a specialized systems with a reduced thickness of the outer walls of the profile. The fact that they appeared and offered on a window market can be easily explained. Manufacturer seeks to produce the maximum number of profile with decreasing its expenses, and as a rule, the calculation is carried out in linear meters, and not by weight profile. Most consumers will not notice the difference in thickness of the walls, think of some tenths of millimeters, but the difference is and it is very important and has implications for both the customer and the producer or window ie the company is an actual deterioration in the quality profile, or product. What happens? The client receives a box of economy – the class with the following deficiencies: – deterioration in the quality of welds due to thin walls and they become more brittle.
– Reduced resistance (stiffness) of the profile (windows) to the temperature changes with changing weather conditions during the year. – The use of lightweight reinforcement. – Deteriorated rigid fixation hardware window, ie in reduced operational safety box. – Poor quality installation of windows, especially in winter tk profile at this time of year is very vulnerable and may just crack and break away when struck. When carrying out installation work hard to put a window in the opening level unnecessarily profile all curved (wave), and is the most important cycle of mounting box.
– Increase in complaints. We have repeatedly offered a lightweight profile, and why – we answer, he is thin-walled. A you remove the stickers, attach the other – we retort. That's how we sell the profile. And from such grief – manufacturers that by lowering prices and a temporary increase in turnover suffer conscientious window company.
Consequence of the pressure of crystallization, are typically very loose / crumbling brick surface. When used on surfaces such exceptional measures to strengthen them, within a short period of time (several months) is observed to enhance the process of destruction. Conclusion: do not proceed without taking action to reduce salt deposits. Likelihood of success of standard methods to reduce salt deposits increased use demineralizer compress deliberately chosen curve screening, cellulosic fibers and absorbent clay mineral. (As opposed to U.S. Mint). Demineralizer wrap must comply with deliberately chosen recipe and related pore bases and their structure. In the near future you can expect to receive the results of research under the eu on the subject. UkreplenieRis. 4: Damaged brick surface Material Used Gamburg.Estestvennye processes fracture of brick, which, besides the already mentioned salt crystallization, include the impact of frost and give rise to the need to strengthen the structure of brick and shattered the surface (Fig.
4). When building brick, the same pattern as in the formulation of similar problems for the damaged surfaces of natural stone. Here we should mention two important points: You should always monitor strength increase from the level surface into the interior brick, ie, main parameter of evaluation – it is not an individual record, and the profile prochnosti.Danny profile strength should not cause large cracks in a small area. They are inevitable during the construction of spans and are associated with medium-term appearance of the crust. Basic reliable methods of strengthening the structure of brick are means based on a silicon efira.Ris.
Attractiveness of individual stores and entire shopping centers for consumers depends on the convenience of location, product range, courteous professional service. But no less important an attractive appearance premises and comfortable lighting to easily find the right shade to choose things – whether it be lipstick, a dress or a wood block flooring. In addition, large stores, where every day there are hundreds of visitors necessary to provide air-conditioning system. As experience shows, in areas with fresh air and comfortable temperatures buyers spend more time, and as a result of increasing the likelihood that it where they acquire the goods they need. That's why when designing a trading hall is planned to design the walls, floor and, of course, ceilings. Suspended ceilings in shops allow us to solve several problems, contributing to increasing the attractiveness of a retail outlet. First and foremost, they help to implement effective room design that emphasizes the image of the store and stimulate consumers to make purchases.
The successful combination of shapes and colors makes shopping mall or a convenience store aesthetic, comfortable, solid, while the cheapest model ceilings talking about is not too serious approach from the owners of the premises. As a result, – Subconscious distrust of visitors and the provision of goods on the shelves, and this inevitably leads to a decrease in sales. Quality rack, tape and other ceilings help to easily and efficiently solve the problem creating a comfortable indoor environment. The space between the floor and ceiling surface coverings can easily hide the ducts of air conditioning systems, leaving visible only the vents themselves.
Due to the seasonality of harvesting is necessary to create serious saw logs and veneer inventories of raw materials for wood processing enterprises. But the stockpiling of raw materials not only leads to the freezing working capital, but also for the inevitable decline in the quality of raw materials and even its loss. And it ultimately leads to higher prices for the cost of production. Reasons for which the decline in the quality raw materials as follows: End of the crack; Fungal and mold damage; Defeats nasekomymi. drevesinyPri natural drying of wood drying in the drying chamber outer surface of the timber quickly dries up, while the inner remains moist, while dried (outer) part of the wood shrinks. Accordingly, in the dried part of the stresses cause the cracks. Cracks in its turn contribute to the smooth penetration of fungal spores deep into the wood. The most intensive moisture evaporates from the end surface of the logs, which explains the formation of cracks in this area.
Defeats mushrooms and plesenyuDrevesina is a breeding ground for various fungi. For their development requires the optimal temperature and moisture content. The optimum temperature for most species of fungi is blue 26-27 C. The most favorable moisture for the development of fungi 35-80%. wood in most cases it has high water absorption rate, "Some types of mushrooms stimulate the development of strong blue wood-destroying fungi. The development of wood-destroying fungi occurs at a temperature from 2 to 35 C, humidity of 20% wood.
