The article describes the basic methods of front tensioning of steel reinforcement and composite smuga behind the help of special outbuildings when folding forward stressed wooden elements and structures. For the essential advancement of the hardness of the elements from the village, which is necessary to apply to the core: increase the strength of the squeezed zone of reinforcement with accessible reinforcement with the highest modulus of springiness, that is, steel; create a buoyant wig for the front tension of the composite stitching made of carbon fiber by Sika CarboDur. The sequence of front tensioning of steel reinforcement and composite smuga without special attachments is broken down. In the new model, it was changed to change the bending of the glued-reinforced combination to the reinforcement of the beam with a track of the front tension of the string reinforcement, which is used in the splice of simple steps without the addition of additional special outbuildings. The buttstock of the front tensioning of the composite reinforcement Sika CarboDur S- 512 was placed on the wood of the stretched zone of the beam without special attachments. Shown is one of the methods of anchoring the composite strіchkovo reinforcement Sika CarboDur S-512. If such a design is put into operation, then when the cob is occupied, її cobs will be extinguished, the forward stresses will be called out, and the last thing will be more likely to bend. In this way, one and the same value of the deflection will be reached with greater equalization of tension, lower without forward tension. The advantage of this method is its simplicity, even if it is not necessary to adjuncts for tensile reinforcement. In addition, for the front tension of the reinforcement in this way, a change in the bending of the gap with the design behind the prototype is up to 30%.
