DEVICE FOR COATING SURFACES OF BUILDINGS WITH HARDENING MASS Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: device has nozzle with slot-like hole, scraper-like cross-member, two side walls, above-slot bar. All aforesaid components are in working relation relative to each other so that scraper-like cross-member is located close to outlet hole of nozzle with slot-like hole opposite to direction of application of coating. Outlet hole of nozzle with slot-like hole is against scraper-like cross-member with respective positioning of above-slot bar. Sections of walls are at both sides. They protrude from plane of surface of levelling scraper-like cross-member approximately to height of layer thickness. Thus formed space which is enclosed at three sides is filled with thick mass due to action of pressure. Device can be operated manually for applying solution or other thick mass in relatively thin layers. Penetration of air is prevented. Surfaces of building to be coated must be preferably flat and can be in any position in space. Aforesaid embodiment of device for application of hardening thick mass is easy and convenient in handling and very efficient. EFFECT: higher efficiency. 13 cl, 9 dwg
