METHOD OF BUTT JOINTING OF CEILING PLATES WITH COLUMN AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC E04B1/22 E04G21/16 

FIELD: construction.

SUBSTANCE: invention is related to the sphere of construction, in particular, to method of butt jointing of ceiling plates with column and device for its implementation. Method includes preliminary fastening of mounting tables on column facets prior to its installation into design position floor by floor. Tables are formed with four support angles with protrusions that are tightened between each other with pins. Protrusions enter into grooves in column facets. Column is installed at design elevation and fixed in design position with the help of strainers. Strainers are installed into lugs of support angles. Consoles are connected to lugs of support angles fixed to columns that are installed in places of sideboard elements and/or balcony plates installation. Prior to ceiling plates allotment on the surface of support angles, horizontal veneer strips are installed with vertical veneer strips fixed to them. End of vertical strips is pressed to column facets, and their surface - to facets of ceiling plates in their allotment. Ceiling plates allotment onto horizontal veneer strips is done with clearance between column facets and ceiling plates, which is equal to 2-3 cm. After allotment of ceiling plates surfaces to be joined are soaked with water. Column facets are connected with slots of ceiling plates by means of stressed reinforcement. Reinforcement is installed through column channels on completion of clearances embedment. Clearances are filled with cement-sand mortar along the whole disk of ceiling plates. After mortar achieves design strength, tension force is transferred to concrete.

EFFECT: improvement of erection reliability, reduction of labour and material intensity.
