Tension ceilings - II
The Tension ceiling represents ideally equal surface (sagging it is not considered), received by a tension of a film of PVC of special structure. To receive a surface of such quality in the traditional ways of furnish, are required big financial and expenditures of labour. Thus old ways do not have such advantages as vlagozashchishchennost, fire safety (class М1), speed of installation (on the average two ceilings in day), durability (to 100 kg / sq., convenience in operation (absence of necessity for special leaving), durability (guarantee period to 10 years) etc. If to it to add that at tension ceilings the big colour gamut and invoices that they do not fade and demontirujutsja easily-are mounted, it becomes clear - the alternative to them simply is not present.
For the sake of justice it is necessary to note and the lacks inherent in tension ceilings: first, fear of sharp subjects and, secondly, relative dearness (the cheapest tension ceilings at the moment stand about 30 c.u. for sq. m with delivery and installation). If the first lack is trudnoustranimym concerning the second it is possible to be assured - in due course it will be essentially lowered. There is also one more lack - a little possibly that on the device of a tension ceiling you could execute works independently if with these have not been connected - let even it will be possible to get all accessories. Such work demands not only the special equipment and materials which are not present in usual shops, but also professional skills.
The Tension ceiling is one of versions of false ceilings though, strictly speaking, it cannot be carried to them as fastening to a base ceiling only as uses one rare enough variant. Usually the ceiling cloth is fixed on perimetre of walls. This way is ideally suited to hide lacks of a base ceiling, and also the engineering communications laid on it, vstrojki fixtures, air lines. It can be used for furnish of almost any premises, including medical as the cloth material is certificated on use for these purposes.
The Film of which the ceiling cloth is made, represents a usual film of PVC of different invoices (matte, semimatte (sateen), glossy (a varnish), a metallic, suede, marble, a skin etc.) Not containing cadmium, thickness of 0,17-0,22 mm, possessing certain physical properties. The ceiling is sewed of separate strips of a film of PVC a cloth found precisely in the sizes of a premise taking into account all its features. For a pattern the professional technologist as in this business, as well as in all questions connected with tension ceilings, it is a lot of subtleties which should be considered at all stages of preparation and installation should do the drawing. After a pattern the cloth is processed on perimetre by a flexible plate - "garpon" which is used subsequently at installation. On it the cloth pattern comes to an end, it carefully washes special means, develops with use of interlaminar linings and is packed into some layers teploizolirujushchej films. In such kind (parcel) the ceiling also is delivered from firm-manufacturer (usually from France) to firm-fitter.
We Will consider this process for the elementary case - ceiling installations in a direct quadrangular premise, without pipes leaving in a ceiling, with the fixture of type "chandelier". This process consists of many operations and can be clear first only to the people having experience of civil work and dialogue with the building tool.
First of all on walls on premise perimetre the baguette representing a plastic profile from rigid plastic or duralumin for which subsequently and it is hooked garponom a ceiling cloth is fixed. Forms of profiles, as well as a way of fastening, at different firms-manufacturers different, though also similar with each other. For performance of this operation the lowest corner of a base ceiling of a premise first of all is defined. It becomes by means of hydrolevel (a flexible transparent tube in length about 10 m, the filled tinted liquid). Further from a lower corner 1-2 sm are measured downwards and the mark a pencil becomes. Really this backlash is necessary only in the technological purposes that it was more convenient to steal up the tool at baguette fastening. Then by means of the same hydrolevel this label is transferred on other corners of a premise. Hydrolevel any more is not required, and it can be cleaned. With the help otbivochnogo a cord with dye the line for baguette fastening is put. For this purpose one end of a cord is established on a mark in one of corners, and another on a label in the next corner, the cord thus should be hardly tense. The cord is delayed by a free hand perpendicularly to a wall and released. Sense of operation in that the tense cord shlepnul on a wall also has left on it dye a straight line from one label of horizon to another. Having repeated this operation for all walls of a premise, we will receive a line of horizon along all its perimetre. This line also will be base for the subsequent installation of a baguette.
The Following operation - exact measurement of corners of a premise. It becomes by means of the special tool - "ganiometra" (a folding protractor) or way of selection zarezok. The second way is more exact. It is better to write at once values of the measured corners a pencil on a base ceiling. Really necessary accuracy - 0,5 angular degrees - to make difficultly as the price of division of the scale used for has washed down corners of a pendular saw more precisely, is equal to one angular degree.
Time krepit on walls a baguette Now has come. For this purpose it is necessary to prepare at first rejku a baguette. By means of a 5-metre roulette the length of a wall on which it is planned krepit rejku is precisely measured. Usually rejka has length of 3-4 m, therefore here the roulette bolshej is not meaningful lengths. If the wall has length, smaller than length rejki rejka it is strict at length zapilivaetsja a pendular saw under the corners equal to half of corners, adjoining to the measured party then it is fixed on a wall so that the baguette upper edge coincided with the marking of horizon made earlier. If walls more than length rejki, last zapilivaetsja only in one corner (the second thus is recommended zapilit at right angle as more often the baguette is cut at length not strictly at right angle), and after its fastening or with the help djubelej and samorezov (of 6 mm and 30 mm are recommended length strengthened djubeli a domestic production in diameter), or by means of a pneumatic pistol and special nails or paper clips with the frequency of fastening defined by a material of a wall. Thus it is necessary to remember that the effort of a tension of a ceiling to a baguette separation approximately is equal 60 kg/m. of the item Missing is increased by a piece of necessary length with corresponding zapilom which fastens to a wall the same or a different way. Having repeated this operation for each wall, we will receive a premise, obagechennoe it is strict in horizon level. Carrying out this operation, it is important to remember that joints of pieces of a baguette should be glued at their connection with the help of glue tsianoakrilatnoj groups.
Then there comes the most exciting period - deployment and cloth installation. As already it has been told above, the ceiling cloth arrives to firm-fitter in the combined kind. Quality of packing can play the important role as even the slightest mechanical damage of a cloth leads to marriage in work. For this reason between cloth layers special linings from the made foam polyethylene or a thin and soft paper keep within. Cloth unpacking should be made in already partially heated-up (to 40-50ОС) a premise. Usually for some minutes the thermal gun joins, and then the cloth should be unpacked and developed cautiously, allowing to get warm in regular intervals (the thermal gun cannot be brought to a cloth more close, than on 1,5. In a ceiling cloth the firm-manufacturer drawing in which "the base" corner should be designated is always put, and there is it so that the base corner was above and the cloth since it was developed. To develop a cloth follows thus: having hanged out on premise corners on rope loops so-called crocodiles (spring clamps in the form of pincers) with the wrapped up two-three layers prokladochnogo a material sponges, we start to develop a cloth. The first the base corner which after small warming up in a thermal stream of a gun clings "crocodile" for garpon opens. Further in process of cloth deployment its new corners which cling "crocodiles" in corners of a premise corresponding to them will open. When all cloth is developed and hooked, while it gets warm to a suitability condition to installation, it is necessary to check up, whether it is correct sorientirovano - though and infrequently, but there were cases of an error to a base corner.
Level to which it is necessary to warm up a cloth, is defined only by experience of the assembler - if not dogret a cloth, he will be difficult for pulling and establishing if to overheat - it will jump out from gearing, but also, the varnish cloth can lose shine. Normally heated-up cloth should be stretched easily enough instead of with garponom and is normal keep in baguette locks. Only after achievement of this condition it is necessary to begin directly installation of a cloth in a baguette. It is possible to begin with any corner chosen by you. The chosen corner acts in film from "crocodile" who is cleaned at once that did not disturb, then the angular shovel is inserted into a groove garpona and with its help garpon cloths is hooked for a baguette. Thus it is necessary to press down garpon fingers of the left hand from above in a place where already it was possible to hook on it for a baguette so that it has not jumped out at once of gearing. Having hooked on a corner, it is necessary to replace a shovel on flat and to continue gearing garpona to the right and to the left from a corner till the moment while garpon it will not be hooked at least for two locks in each party.
Further are similarly hooked opposite and other corners. That each subsequent corner is hooked all more difficultly, it is necessary to consider normal.
When all four corners are established, it is possible to start gearing of direct sites. It becomes already by means of direct shovels and priblizitelej. At first on two-three locks sites in a place of the termination of seams of cloths - so less probability of occurrence their curvatures are hooked subsequently. Then loose sites are halved and in the centre are fixed besides on two-three locks. So until the size of loose sites will not be such that all site could be fixed with little effort (usually it to 1. Further definitive gearing on all perimetre of a premise is made. When it is made, it is necessary to check up quality of gearing of a cloth on all perimetre, having checked up density prileganija ceiling cloths to a baguette. If in any place the cloth leaky adjoins to a baguette, it is necessary to correct gearing. If all is correct, the cloth hardly enough tense on a baguette forming ideally equal surface turns out.
Last operation - the device of the fixture of external installation (chandelier). The first that it is necessary to make, it to prepare an intensifying ring. It is usually made of plastic in the thickness of 3-4 mm. Plastic should combine mutually exclusive requirements - strong and easy in processing. It is possible to recommend the made foam plastics of mark KOMATEH. External diameter of a ring should be such that the cup of its chandelier covered, internal - such that the ring was easily put on the hook of a chandelier fixed in a base ceiling. In any case the width of a ring should not be less than 5 mm. Usually this condition is easy vypolnimo. Naoshchup through a ceiling cloth find a chandelier hook, and in this place the mark a felt-tip pen becomes. Type glue is put on an intensifying ring tsianoakrilata by a continuous strip without ruptures. This condition is obligatory, differently subsequently the ceiling cloth will spread, as a stocking full of holes. After that the ring is pasted on a cloth face sheet so that the mark made a felt-tip pen was precisely in the centre of an intensifying ring. Glues of the specified type dry usually within several seconds, therefore, having sustained specified time, small obojnogo in a ring the cloth is cut out by a sharp knife of type, in the received aperture the wire is extended, connected to a chandelier, and then the chandelier is simply hung up on an old hook which, if necessary, is increased at length.
Such is sequence of operations at installation of the elementary tension ceiling - four corners and a chandelier. More difficult ceilings including pipes, the built in fixtures, circular elements, and even transitions of levels, demand the description. It is not necessary to think that it is very simple. As it was already told, if you have dared at installation of tension ceilings, charge it to professionals.
