Here even two ways of installation of beacons:
a Fig. 42. A rejka-beacon
the First way - proveshivanie walls by means of strips of dry plaster. It is assured that on any today's building even if furnish of walls by dry plaster here is not provided, will not present work to get its waste. And benefit will be received the appreciable.
For beacons the strip of dry plaster in width 4 cut see In small premises (the area to 12... 15 m 2 ) where can be established 2... 3 beacons, we arrive as follows. From a corner on distance 20... 30 sm on a vertical put a continuous layer gipsoopilochnoj mastics (about it read in gl. " Substitutes monolithic °=ѕър=ѕЁъш"). On it impose a strip of dry plaster, press the big rule with a plumb. The second beacon puts through 2,8 m from the first, the third - between them.
Horizontal position of all three beacons under the relation to each other check a three-metre rule.
In the big premises at first check walls a cord on a diagonal. Then establish on corners beacons on distance 20... 30 sm from a corner. Put a cord on these control beacons below, near a floor and establish on a cord on mastic of mark from scraps of dry plaster in the size 3X4 the Distance between beacons of 1,5 m. see
The Same operation repeat above, about a ceiling.
After that put beacons from strips of dry plaster zapodlitso with marks, pressing their rule.
After drawing of a ground beacons remain in it. Them then together with definitive furnish of a plane will close nakryvochnyj a layer.
When impose majachnye strips on mastic, it is necessary to miss the mark with the same mastic from both parties of an edge of strips. If it not to make, there can be cracks in plaster. Performance told above the requirement guarantees integrity of a plaster layer, and beacons will be absolutely imperceptible on a wall.
The Method of installation of beacons from dry plaster accelerates this operation in 8... 10 times.
the Second a way proveski planes - use of inventory marks-beacons (fig. 43), Thus become unnecessary both nails, and beacons from dry plaster.
a Fig. 43. Inventory mark-beacon :
1 - djubel; 2 - a metal plate
Mark represents djubel, welded on a metal plate in the thickness 4... 5 mm, the size 40X30 mm.
Unlike a nail, djubel, as it is known, easily enters into any wall, even the concrete.
Having receded from a corner on 30... 40 sm, hammer in the first mark into the top part of a wall. The second mark put below and both check rejkoj with a plumb. Having checked up a cord on a diagonal a wall, two marks above and below on an opposite corner put. Further arrive the same as at beacons from dry plaster: pull for marks a cord below, at a floor, put on it intermediate marks on distance 1,5... 2 m from each other. Repeat the same operations above, at a ceiling. Pulling serially a cord for control marks, put on a plane of all wall the necessary quantity of intermediate marks.
After ground drawing the metal mark is easy for taking out and using again on other site.
Using inventory marks, having armed with a metal step-ladder and control rejkoj with a plumb, the worker can easily and quickly carry out provesku walls. Labour productivity raises three times.
At great volumes of monolithic plaster use also metal inventory beacons, they are very convenient. These beacons are made of steel or dural corners by section 20X20, 25X25 or 30X30 mm, them krepjat to a wall by means of special probes with a nut. At first put, verify and fix extreme beacons. Then between them on hardly tense cords place the intermediate.
Apply shtukatury and horizontal beacons from a solution and strips gipsokartonnogo sheet.
On fig. 39 wooden horizontal beacons are presented. By the same principle began to do and other horizontal beacons, including their more rational, progressive. Begin provesku in a following order: at first it is necessary control rejkoj with a plumb to check up walls, to define deviations on a vertical, then to prepare a solution of a dense consistence and to put marks. They need to be made in each corner only two - above and below, having receded from a corner on 30... 40 sm, and from a floor and a ceiling - on 50... 60 see For faster shvatyvanija in a solution it is possible to add 5... 10% of plaster. To throw a solution it is necessary to try so that the mark had a high cone.
On a solution put a slice of dry plaster in the size 5X4 sm, the wide party should settle down vertically.
Rejkoj with a plumb slightly press marks, establishing them it is strict on a plumb in one and other corner. Then pull a cord on angular marks above and below, put intermediate marks through 1,5... 2 m depending on length of a wall also rub the top and bottom beacons.
Horizontal beacons have the advantage at mechanised soplovanii walls. One worker with the help rejki in 2,5... 2,7 m are levelled easily by a solution on all wall. Behind it the second worker and masterkom follows or a ladle selects the fallen solution, again starting up it in business on separate sites and there and then levelling poluterkom. Only it is necessary not to forget before soplovaniem to tide up, that on a floor there was no dust.
If is not present on object of dry plaster, for marks it is possible to use slices beaten glazurovannoj tiles. The form can to be selected - if only there was a rigidity for a rule support.
As it is possible to apply and wooden marks - to use plates from boxes from under a tile. Plates here thin and nestroganye - just such what are necessary.
