The joint is covered with a coupling, the position of which is fixed with a support ring.EFFECT: elimination of welded joints making during assembly, reduced effect of subsidence phenomena in concrete at structure operation and elimination of longitudinal shift of concrete under load.1 dwg

ethod of stiff connection of tubular crossbar oval in section with guncrete carcass pillar oval in section // 2472905
FIELD: construction.SUBSTANCE: bent crossbar is stretched via a unit as indivisible, solid. The lower pillar cap is arranged as trough-shaped with longitudinal bent ribs. The cap follows and covers the oval surface at the bottom. The crossbar is tightly inserted into the pillar cap, matching fixing pins with responsive holes in the cap trough. The base of the upper pillar is arranged same as the cap - trough-shaped, and is equipped with fixing pins with response holes in the cap bends. The upper pillar is mounted in a non-adjusting manner, matching fixators with responsive holes, and an oval tubular cavity is formed with the cap trough. The crossbar inserted into the cavity is tightly covered. Longitudinal ribs of the upper pillar base and lower pillar cap are connected to each other, for instance, by high-strength alloyed pins. They are securely tightened with a nut setter, and a single monolithic unit of pillars and the crossbar is created.EFFECT: automation of a process of structure carcass erection, increased manufacturability of a process, reduced labour intensiveness and higher reliability of connection.12 dwg

ethod to arrange joint units "column-crossbars-column" // 2471931
FIELD: construction.SUBSTANCE: method to arrange joint units includes installation of lower columns, crossbars, ceiling slabs, upper columns and monolithing of column joints with crossbars and upper areas of crossbars. Lower and upper columns are columns of floor sectioning with holes in upper ends and reinforcement rods in lower ends. A conductor is fixed at the end of each column prior to assembly. The conductor forms between its body plane and the upper end of the column a space for a monolithic node joint and a hole for reinforcement rods in a finished joint. Precast crossbars are installed at the ends of columns, providing for contact of double-sided slopes of their support ends with setting columns of conductors. Monolithing of column joints with crossbars and upper areas of crossbars is carried out prior to removal of conductors from ends of lower columns. Conductors are removed from columns after formation of an initial structure of concrete in a ceiling. Upper columns are installed after concrete gains design strength, connecting them with the lower ones by means of a plug joint.EFFECT: reduced metal intensity, higher accuracy of performance, liquidation of welding and forming works on a construction site.5 dwg

End dowel joint of wooden beam structures // 2471930
FIELD: construction.SUBSTANCE: connection of wooden beam structures comprises a connection part attached to the surface of beam structures with holes and dowels arranged in holes of the connection part and body of beam structures. The connection part is arranged in the form of an end plate and a plate element installed perpendicularly and rigidly connected with it, attached by pads to beam structures. The end joint is equipped with a bolt tensioning device, and a dowel is rigidly connected in holes of the end connection part. Dowels may be made from reinforcement of periodical profile and are arranged in the body of wooden beam structures on glue.EFFECT: higher joint reliability.6 cl, 8 dwg

Nodal joint of spatial structure rods // 2468157
FIELD: construction.SUBSTANCE: nodal joint of spatial frame rods includes round discs, between which rods joined in a node are arranged. The nodal joint is equipped with connection bolts installed in holes along perimetre of discs, besides, there are holes made in discs, and edges for the possibility to change the horizontal angle of rods adjacency are arranged in the form of straight gears, in which in process of assembly tips are fixed, which in their turn are again equipped with straight gears for the possibility to change the vertical angle of rods adjacency.EFFECT: reduced labour intensiveness of construction and assembly works and universality for application in rod systems with various angles of rods adjacency within a single structure.5 dwg

Nodal joint of spatial structure thin-walled rods // 2467133
FIELD: construction.SUBSTANCE: invention refers to the sphere of construction, in particular, to a nodal joint of thin-walled rods of a spatial structure. The nodal joint of thin-walled rods of the spatial structure comprises a connecting element in the form of a cylinder. Cylinder dimensions provide for jointing of the necessary number of rods. Attached rods of "П"-shaped section are cut in places of crossing between walls and a shelf of a rod. Walls are bent outside along a radius corresponding to a radius of curvature of a connecting element. The shelf is bent down until full adjacency to the inner face of the connecting element.EFFECT: simplified manufacturing, assembly and reduction of node weight.2 cl, 9 dwg
