Rolstavni
To write the article about rolstavnyah I has decided not so much on the instructions of edition, and is faster on heart command. This theme for me is especially actual, because I have lived 20 years of the hard life in apartment on the ground floor. Tortures which I and my house daily tested to transmit words it is impossible. Those who beduet, as well as I, that is tenants of the ground floors, understand, about what speech. But also more vyisokoetazhnyim to citizens I advise this article to esteem. Whether it is not enough, how the lifewill develop?
Our apartment in general is possessed extremely unsuccessfully – near to a source door in an entrance. This lax and creaking durischa served us as something like an alarm clock: every morning we amicably woke up hours per six when at tenants of our house day of work and they, loudly clapping a door began, left for work.
Not less exasperated us street noise and curious sights of passers-by. They perceived our windows as the TV screen, and ourselves – characters of a serial of "a life Trifle»., what ornament at me on an apron all the quarter long was well informed, how many buttons on a mum’s dressing gown with whom I drink tea on the kitchen, what furniture costs in a drawing room and that we make for a supper. I distinguished neighbours (and their dogs and doggies) on voices, knew their mode of day, was well informed their personal, I even would tell intimate, lives which was continuously discussed (and sometimes, excuse, occurred) literally under my windows.
And thieves, these domushniki-peredvizhniki! What did they should get to such apartment, how ours?! And the boys carefree driving a ball before our windows! How many time because of the next it is inexact the sent pass to us it was necessary to insert the broken glasses! More shortly what here to tell, and so it is clear. Not a life, and penal servitude.
And here in one fine day nerves at us have not sustained, and we have delivered iron lattices on windows. Certainly, in sense of malefactors the sensation became quieter, but, that we live in the street, and the street lives among us, did not leave. With the advent of plastic windows we have made the second attempt to solve a sore problem. With easy heart have left old wooden frames, having replaced with their nice plastic profiles with double-glazed windows. At last in apartment it became warm and silent. Daily "political information" and other disgraces behind a window did not infringe now our rest. At least, if we something also saw such then did not hear. But the mania of prosecution still remained family illness. And if not casual coincidence of circumstances, direct road to us to the psychoanalyst. Or than that is worse – in the establishment named in the people shortly, but it is capacious – in a madhouse.
Contingency is already law!
I came back somehow home, I look – outside, before a window of my neighbour (on hearings, the person rather well-to-do), any muzhik looms. The first impulse was to cry: «Sentry! Plunder!». And to cause militia. But, having looked narrowly, has understood – it is somehow unlike a robbery. But just in case has vigilantly decided to come to the neighbour and to find out, in what business. I call at a door – leaves. It is concentrated, efficient. In a suit. A tie silk, on the first impression – it is obvious not the Korean. On a hand good hours have languidly flashed. Has suggested to enter, drink tea-coffee. Have got to talking.
It has appeared, the person behind a window which I have accepted for the robber, established rolstavni. The neighbour has explained me as has managed, that this such. Then our conversation has left aside, about more personal. And behind more detailed information apropos rolstaven he has advised to address to firm "Radial". Has told, that firm solid, exists for a long time and manufactures very strong rolstavni which tests for breaking, by the way, repeatedly passed and with honour them have sustained. Probably, not casually, he has told, rolstavni "Radial" are established in large Russian banks. «Aha, it the banker!» – I have thought, – suits! Also began to estimate, as though to make more elegantly so that it there was not last our conversation … But I have distracted.
… And meanwhile, while we lovely talked, the assembler has finished the work. I have approached to the closed window and have asked to lift the owner shutters. He has offered: «And you try», – and has indicated the button near to a window. (Has forgotten to tell, we have already passed on "you".) And so, I have cautiously pressed the button – rolstavni have gone upwards. Has again pressed – have fallen. «It is amusing!» – I have thought. In general, the decision was accepted definitively and irrevocably, and I have asked a phone number of this firm. (It is not necessary to speak, as a phone number of the neighbour – too. Say, whether it is not enough, suddenly then it will be necessary to consult about my new purchase. Meant, of course, rolstavni.)
On following put I has called on firm. To me have very kindly suggested to arrive on constantly acting exhibition «Rosstroyekspo» on the Frunze quay. To look, listen, choose.
Has arrived. Also has got acquainted with Sergey Nikolaevichem Sidorov and Alexander Petrovichem Ivanov, representatives of firm "Radial". Yes, has forgotten to tell, that previously I have received the editorial task to write the article about everything, that I learn.
But before I will inform with you, expensive readers, all details, I wish to tell thanks all employees of the firms, which distances to me such detailed and exhaustive information about rolstavnyah.
And if it is interesting to you, that I know now, is ready to inform with you.
So, the first. Rolstavni is not that other, as the protective jalousie which are turned off in a roll. Basically, visually they are similar to usual jalousie, but unlike them at rolstavney other, more serious functions. A basic purpose rolstavney – protection of windows and doors of offices, banks, shops, trading pavilions, garages, apartments and apartment houses. As a rule, rolstavni establish outside. So they are more difficult for beating out, and it is absolutely impossible to break glass which they urged to protect. Because they protect a premise not only from solar beams and inquisitive sights of passers-by, but also from those who does not like to go through a door. Differently, strong shutters reliably protect from thieves.
If to speak about "anatomy" rolstavney they consist from:
– Cloths which is made from lameley, or, in another way, profiles (the horizontal laths fastened among themselves by hooks);
– Directing on which the cloth moves upwards-downwards;
– A box in which shutters "leave", being turned off in a roll;
– A shaft;
– Bearings.
Appearance, functions and the price rolstavney depend on several factors: from a material of which they are made, from the sizes of details (in particular, width lameley), from weight of a cloth and from a method of management. We will try to understand with these four components.
Material
Usually rolstavni, is more exact lameli of which the cloth consists, do of aluminium or a steel. Aluminium, as is known, metal soft, but in an alloy with silicon and magnesium, for example, it becomes strong enough. With a steel and so all is clear – at it «iron character». However a steel – the person "whimsical": it needs to be preserved against scratches carefully. After all, unlike aluminium, it rusts.
Aluminium profiles (lameli): ekstrudirovannyiy and with penopoliuretanovoy "stuffing"
Lameli (profiles), aluminium and steel, happen a different thickness and density, depending on a manufacturing method.
Let’s tell, take two thin sheets of aluminium (steel) and between them lay penopoliuretan, and then all fasten it the special adaptation reminding a press. By the way, penopoliuretan use teplozvukoizolyatsii. So that rolstavni, produced in such a way, save 30 – 40 % of heat indoors.
There is also other method of manufacturing rolstavney. The profiles made on this technology, are called ekstrudirovannyimi. Process of their production reminds forcemeat preparation. The profile of the necessary form "creeps out" of the special car – ekstrudera, as meat from a meat grinder. Lameli are received thin, but more rigid, than made the last method. As I was demonstrated by experts of "Radial", the panel maintains more than 50 blows by a sledge hammer.
Service life aluminium ekstrudirovannyih rolstavney – 4 – 5 years, and steel – 2 – 3 years.
And still: rolstavni, executed from a steel, is much heavier and more expensive than the aluminium. After all more powerful electric motor is necessary for a heavy design, which, naturally, not cheap. Besides, steel rolstavni require ideal installation – the slightest warp of a design at installation will cause load on lameli. And it, in turn, will affect ease of opening and closing rolstavney. So that it is not excluded, that not once it is required to take advantage of services of technical repair service.
Not casually, on supervision of experts, for last years five in Russia mainly order aluminium rolstavni, instead of steel.
The sizes and the prices
What it is necessary to know about protective jalousie (so still name rolstavni)? Keep in mind: durability rolstavney directly depends on width lameley. The more widely lamel, the the cloth, and on the contrary is stronger. Usually width of an aluminium profile 37 – 77 mm. This characteristic too is reflected in packing. It looks thus: for example, A37 (the letter And designates aluminium, figure 37 – width lameli in mm), A40, A45, A55, A77. The price of aluminium profiles fluctuates from 70 to 150$ for 1/sq.m. depending on width. The steel profile is designated, accordingly, S40 (With – a steel, 40 – width in mm), S55, S77. The price – from 100 to 160$ for 1/sq.m.
Methods of management rolstavnyami
I already said, that protective jalousie can be established anywhere: indoors (in window or a doorway), outside (in garage, on a summer residence, at windows). The Location essentially will not affect a choice of a method of management. Because it depends first of all on weight of a cloth. There are two methods of management rolstavnyami – mechanical and automatic.
Mechanical control
Most simple and inexpensive (20 – 25$), it is intended for an easy aluminium design, weight to 15 kg. A principle of work of tape management same, as at a seat belt in the car. The box with a tape is established indoors near to a window. To close or open rolstavni, the tape needs to be taken out from a box and to pull on itself (as in usual jalousie). If at you rolstavni tape management is advised to establish on bottom lameli the mechanical lock (the price 20 – 40$). To block rolstavni, them it is necessary to lower, close the lock and to take out a key.
Tape management (at the left), Trosovoe (reduktornoe) management (on the right)
This method suits heavier designs (weight from 15 to 25 kg). The tape is replaced here with stronger cable (the price 35 – 45$). The operating mechanism, as well as in a case with a tape variant, is established indoors. A difference that rolstavni podnimajutsja-fall by means of the handle which is built in in a box for a cable. Rotating the reducer handle (the wide gear cylinder in which the cable is inserted and reeled up), you force to go rolstavni there-here. To block a design it is possible and by means of the mechanical lock – it establish on bottom lameli.
It is intended for designs in weight to 35 kg (costs 60-70$). As in the previous cases, the box in which there is a control system, places at a window indoors. Rolstavni actuate, rotating the handle. But unlike trosovogo managements, this mechanism more difficult. A reducer joins kardan (a thin long metal core). Kardan connects the handle possessed below, and a reducer possessed from above. It also sets a cloth in motion.
Automatic control
The box in computer-controlled models superficially resembles a box in "mechanical" variants. And here contents of this "box" other: inside there is an electric motor thanks to which without special efforts it is possible to open and close rolstavni.
For garage, office or a country house there is a sense to order rolstavni with electric management
Correctly to choose the engine, besides it is necessary to consider cloth weight. For heavier design more powerful is required and, hence, more expensive engine. Electric drives of the German firm "Somfy", which price – from 170 to 650$ are most popular. The Average cost of the engine for a design in weight to 18 kg – 180$, to 74 kg – 260$, to 157 kg – 640$.
There are two kinds of management of an automatic design: push-button and remote. Push-button management is easier and cheaper (15 – 30$). Outwardly the management button reminds the switch, and it the same as the switch, fastens to a wall. Having pressed the button, it is possible to lower or lift rolstavni. At desire the button equip with a clamp. In this case simply enough to touch the switch that the design has gone downwards or upwards. If you have chosen the push-button switch in «bezfiksatornom» performance to lower or lift rolstavni, it needs to be kept until the cloth will not be lifted or will not fall up to the end. That it has stayed, simply clean a finger from the button.
Remote control – the most "abrupt" and convenient method of management rolstavnyami. But thus and most expensive (350 – 400$). You, probably, have already guessed, that rolstavnyam commands from the panel reminding the panel of the TV move. To press one of buttons enough – and rolstavni there and then come to movement. Remote control is reasonable for applying there where it is established a little rolstavney: to lift protective jalousie simultaneously in several rooms, on different floors. If, of course, you have not forgotten to connect them to control centre.
Automatic control (push-button or remote) apply to heavy designs in weight from 35 kg
Automatic control at will of the client can be added by emergency system with the combined electric motor. If you have a sharp requirement continuously to open and close rolstavni in the house, and the electric power disconnect very often, this system for you it will be simple a lifesaver. In this case to close or open rolstavni it is possible manually, with the help kardana which establish near to a box: simply twist the handle, and rolstavni come to movement. However, there is an emergency control in 1,5 – 2 times more expensively electric. To block system, it is necessary to be spent and deliver in addition the automatic or mechanical lock in the bottom of a cloth.
Automatic control with the gauge. At first just in case I will explain, that such the gauge. This system accepting, data of any measurements reformative and transmitting to special devices or, easier speaking, signals. In practice it looks so: on rolstavni computer-controlled put the gauge and set to it the program. Depending on this program it will submit signals and to lower rolstavni during certain time of days.
For what? For example, you long are absent at home. And the house at you quite good, and it, naturally, draws attention of robbers. And so. The gauge will create «effect of presence», lifting and lowering protective jalousie, suppose, two times a day. Besides, he can "order" it to fall, if in a window fries the sun or the strong wind was lifted. Very clever mechanism, I will report on you.
«Study to live widely»
Having listened to all this most detailed information, I, clearly, have lighted up idea to deliver on windows such "clever" rolstavni. As in firm will help both to choose, and to establish rolstavni. In general any firm before to sell protective jalousie, should calculate precisely a parity of weight of a design and a method of management (for this purpose rolstavni there pass serious tests) and, naturally, to consider desires of the buyer and its possibility. The slightest error in accounts can lead to an emergency.
I will explain on an example. One square metre of steel protective jalousie with width of a profile 40 mm weighs 9 kg. And aluminium rolstavni the same sizes 4 kg weigh. The main thing that is required from the customer, – to indicate exact dimensions of apertures where rolstavni will be established, and to choose that he wants: a material (a steel or aluminium) and the sizes lameley. Choosing a method of management, it is necessary to consider some nuances: the mechanical variant, unconditionally, is cheaper than the automatic. But if you decide to save and will start to lift and lower manually wide steel jalousie, efforts will not be gathered. Though very much can be, that your beefy bicepses will be envied shortly by Schwarzenegger.
On the other hand, all the same for garage, office or a country house there is a sense to order rolstavni with electric management. In this case it is unimportant, steel they or aluminium. More important other – they hardly will facilitate to you a life. And here in apartment it is quite possible to manage tape or trosovyim a variant.
Personally to me, a victim of the ground floor, have advised to deliver stronger rolstavni from ekstrudirovannogo aluminium with a wide profile. They strong, but not heavy, do not rust and is cheaper than the steel. Having saved thus money, I have chosen push-button automatic control.
However, before new acquisition has appeared at my windows, it was necessary to practice in the mathematician fairly. At first it was necessary to calculate the cloth price: the sizes of a window to increase by cost of square metre (2,85 sq.m. h 100$ = 285$). Then to find out, the chosen aluminium cloth how many weighs, and to be defined with method of management. It has appeared, that my jalousie have pulled on 15 kg (1 sq.m. of aluminium in width of 55 mm weighs 5 kg). Basically any method of management approaches to such shutters, beginning from most the elementary tape (I already said, that it is calculated for a cloth in weight to 15 kg). The automatic variant with push-button management will manage on the average nearby 200$. The bottom lock – 30 more $. As a result rolstavni have managed to me in 505$. To this sum, the truth, it is necessary to add still an assembly cost (indoors – 15 % from the order price, outside – 20 %) and deliveries (at each firm the quotations, but a difference small).
As a result all pleasure has managed to me approximately in 600$ for one window! And at me their three. How many it is received in the sum, count. But I do not regret. If I have not delivered protective jalousie would lose it is much more: both nerves, and health, and the acquired property. Yes, besides other pleasures I have received one more. I communicate now with ours the neighbour, the truth, purely friendly. All of us have appeared different for more close contact. And the husband I to myself absolutely other have looked after, soon wedding.
P. S. «To delegations and zhenotdelam discounts» (Ilf and Petrov).
Has forgotten to tell. As a rule, at the order of several cloths of protective jalousie of firm grant quite good discounts. Besides, discounts act in the autumn and in the winter, that is in «nesezon».
