Polyme rpipeline lifting support

FIELD: transportation.

SUBSTANCE: polymer pipeline lifting support is made as hollow thin-walled body with a rectangular base, inclined trapezoidal side walls and upper support surface of a saddle shape comprising technological holes. In a central part the support comprises an internal cavity with an open rectangular-shaped top formed by the inner walls and the bottom, positioned on a level with the base, and side inner and outer walls are made in the form of a subdivided stepped structure.

EFFECT: increase of the strength and stability during the mounting on a pipe support, lightweight design, providing simplicity, convenience and reliability in use, efficiency and reliability in storage and transportation.

SUBSTANCE: method to install a sleeve line along a building staircase height in gaps between stair flights and between rails of their barriers consists in the fact that additionally technical inspection of a staircase is carried out, as well as calibration calculations for strength and deformability of barrier elements of stair flights and stair platforms. Then values of gaps are measured in plan in clear between stair flights and rails of their barriers in conventional points of crossing of ascending rails of the barrier and descending stair flights, then, with account of the width of gaps between stair flights and between rails of their barriers, support and/or limiting elements are made, fixing them tightly at one end to a strip steel tape of a barrier rail and/or to a stand of a barrier grid of a ascending stair flight and at the other end - to the lower face of the descending stair flight, with support and/or limiting elements installed horizontally and/or vertically to axes stretching via conditional points of crossing of ascending rails and descending stair flights, an area is developed for free installation of a sleeve line along a building staircase height.

EFFECT: improved operational properties according to a bearing capacity, rigidity, lower instability, higher security of public in case of their forced evacuation from buildings and structures.

SUBSTANCE: transformable non-demountable folding construction gallows comprise a non-demountable four-legged metal construction consisting of two triangular braced structural elements relative to installed gallows, which are connected at the base and peaks with horizontal cross bars, of which the upper one is intended for installation of scaffolding above it.

EFFECT: simplifying and speeding up preparation of working place prior to execution of work, economy of shaped timber.

Support strut // 2268975

FIELD: building, particularly attachments to perform construction-and-assembling operations.

SUBSTANCE: support strut comprises telescopic lower pipe with threaded end, adjusting nut and fixer, as well as upper pipe with orifices for fixer receiving with stopping means. The strut also has rotary supporting unit mounted in lower part of lower pipe and arranged from outside thereof. The threaded end is made as adapter sleeve with stepped outer surface. The adapter sleeve is partly inserted in lower pipe by part thereof having lesser diameter and is fixedly secured to upper end of lower pipe, for instance by welding thereof. Adapter sleeve part having greater diameter is provided with longitudinal cuts and with thread having semicircular crests. Gap of 3-4 mm dimension is created along threads of the sleeve and the nut after application of coating having friction coefficient lesser than critical one. The gap extends along the full perimeter thereof. The adjusting nut has extension. The fixer is arranged above the adjusting nut and is made as rigid closed contour surrounding sleeve part of greater diameter. The fixer may be shaped as oval and is provided with support pin arranged inside the fixer and extending along longitudinal axis thereof. The support pin freely enters in upper pipe orifice and in sleeve cuts during connection thereof. Pin length exceeds sleeve diameter. Upper pipe have bearing installed in upper part thereof. The stop is made as collar connected to lower part of upper pipe. The pipes are prestressed.

EFFECT: increased reliability and service life.
