METHOD AND DEVICE FOR FORMING GUIDE STRIPS ADAPTED FOR LEVELING UNDERLAY ARRANGEMENT Russian patent published in 2006 - IPC E04F21/20 

FIELD: building, particularly implements for floor laying.

SUBSTANCE: method involves cleaning sub floor surface so that waterproofing material may be applied on the sub floor; marking the room to determine places of guide strips arrangement; installing shaping device for mortar pouring along marking line; installing cutting device on half-formed guide strip made as pre-formed mortar structure; determining and setting horizontal plane of transversal half-formed guide strip cut with the use of bubble level and two frame adjusting screw; taking necessary vertical guide strip line determined with the use of laser level as predetermined design mark; cutting half-formed guide strip top up to necessary guide strip level; filling the shaping device with residual mortar and repeating above operations; forming leveling floor underlay with the use of above guide strips. Device for above method implementation comprises shaping device and cutting device. The shaping device comprises box-like body with at least one opened end. The body consists of upper hopper-like part and lower part having cross-section made as isosceles trapeze with enlarged lower base. The cutting device includes support wall and frame provided with guiding means arranged along both frame sides. Installed between the guiding means is blade, which is secured to slides to perform longitudinal and horizontal blade displacement. The slides are displaced along guiding means in horizontal direction. The cutting device has level arranged from both cutting device sides and adjusting screw to provide frame horizontality. The cutting device also comprises screws to adjust blade movement in vertical direction and with rotary laser level. Ruler with laser beam receiving means is installed at blade ends near adjusting screws.

EFFECT: decreased guide strip surface plane deviation from predetermined level, reduced time of guide strip forming.
