A composite structure apparatus for determining the interaction forces and reactions of the three pillars

摘要

The invention relates to laboratory equipment and can be used in teaching laboratories on Theoretical and Applied Mechanics of technical universities, colleges and technical schools.; The task to be solved by the proposed utility model, is to reduce the material consumption for the manufacture of a composite structure due to unification of the constituent elements.; The technical result is achieved in that in the composite constructions of devices for determining the interaction forces and reactions of three poles mounted on a frame and comprising left and right portions interconnected by an internal swivel joint, wherein one part of the composite structure is pivotally connected to the frame by means of two supports , one of which - a stationary pivot joint, the other - pivotally-movable support and the other part of the composite structure is linked to the frame by means of pivotally-movable support or weightless rod I, the left and right sides of a composite structure composed of structural elements, rods, according to the proposed utility model, the composite structure is a composite set of standardized elements adapted to build unified elements: a frame, three legs made demountable, structural elements- rods, made as a set of elements consisting of rectilinear, polygonal rotated T-shaped, U-shaped and W-shaped bars mounted on the supports, wherein unifi th e bed is provided with three removable brackets and consists of upper and lower L-shaped trough halves with support plates rigidly attached to the short sides of the L-shaped trough halves and rests against the long sides of L-shaped trough halves in rigid which bond formed rigid closed rectangular contour movable upper and lower L-shaped trough along the frame halves to one another.; Such a composite structure execution devices for determining the interaction forces and supports three reactions has greatly reduce the consumption of material for their manufacture due to unification of the constituent elements. 7 yl.
