Famous bridge farm crane, consisting of the main and sub beams in the cavity of the box girder by welding reinforced elements that increase its strength against twisting and buckling (patent of Russian German N 2853658 from 27.01.1983, MPK7 B 66 C 6/00).

The existing load-bearing elements are designed for a maximum load corresponding margin of safety. This load they experience extremely rare, but the weight of the ballast are constantly.

Known bearing element structures of buildings or structures containing enclosed in a shell bearing center plate, covered side disposable plates with a positive radius of curvature, based on the elastic membrane loaded by internal pressure generated by an external pressure source (RF patent N T from 28.08.1998, MPK7 E 04 C 3/07).

Described bearing element adopted for the prototype.

Known design and are cost structure, increasing its strength, reliability and other consumer qualities.

Technical task, which directed the claimed design is further proportional increase stability of the bearing member with increasing external load static or variable.

The problem is solved in that in the multipurpose bearing element structures of buildings and structures containing enclosed in a shell bearing center plate, covered side disposable plates with a positive radius of curvature, based on the elastic membrane loaded by internal pressure generated by an external pressure source, put one, two or more active resistance mechanisms placed in the longitudinal center plane of the plate at locations of expected maximum tension and compression pivot plate when the external voltage, with active resistance mechanisms is made in the form housed in a casing with a working medium of a multiple piston (f) set with the rod, moreover, sections of the housing through the distribution pipeline, and a collector connected to the external pressure source and the piston and the rod, and each of the used liquid, powder expanding and hardening of the mass, for example, alabaster, gaseous substances or combinations thereof, depending on the type of operation (stationary object or mobile).

The connection of the piston or the piston rod and each section of the casing with metal plates made, for example, by means of locks.

The invention is illustrated by drawings, where:

in Fig. 1 - shows a cross-section of the multi-function support member structures of buildings and constructions;

in Fig. 2 is a schematic diagram of a longitudinal section of the active mechanism of resistance with symmetrical with respect to the axis of the shaft by the piston and asymmetrical;

in Fig. 3 is a longitudinal cross-section of the section of the active mechanism of resistance;

in Fig. 4, 4A - plot distribution of forces when loading multi-function support member structures of buildings and structures.

Multifunctional load-bearing element structures of buildings and constructions contains enclosed in a shell 1 metal center plate 2 covered side metal plates 3 with a positive radius of curvature, based on the elastic membrane 4, which is loaded by the internal pressure created by the outer East is Noah the plane of the center plate 2 in the expected places of tension and compression the center of the plate 2 when the external loading, this active resistance mechanisms 6 made in the form accommodated in the housing 7 with a working medium 8 multiple piston 9 with the rod 10, with the housing cavity 7 through the pipes 11 and the collector 12 is connected with external sources of pressure 13 and the piston 9 or the rod 10 and each section of the housing 7 connected with the metal plates 2, 3.

As a working body 8 can be used in liquid, powder curing and expanding mass, for example, alabaster, gaseous substances or combinations thereof, depending on the type of operation (stationary or transport).

The connection of the pistons 9 and the rod 10 and each section of the housing 7 with metal plates 2, 3 is carried out using, for example, locks 14.

The operation of the multifunctional support member structures of buildings and structures is as follows. Under the action of external loads, which may be concentrated, distributed or mixed start to deform the center plate 2, the stability of which is insured side plates 3, which in turn propped up perpendicular to the plane of the center plate 2 distributed gavlenebis body type alabaster proportional to the external load.

In turn, the elastic membrane 4 is based on the outer shell 1, which forms the outer case element multifunctional support member structures of buildings and structures.

Active mechanisms 6 resistance to axial load and, as shown in Fig. 4 schematically external load deforms the element beams so that the neutral axis of the bend radius R, without changing the linear dimensions. At the same time the shell at radius R1is compressed, and the radius R2is stretched.

To compensate for these deformations in the design of multifunctional load-bearing element structures of buildings and structures provided by the system of active mechanisms 6 resistance, in which the pressure is supplied from an external source 13 is proportional to the external load for transport systems, or permanently from mechanics enlarged powder mass under the maximum external load for stationary systems.

Work multiple piston 9 is functionally connected with the external load and, in particular, with changes in the linear dimensions of the arcs R1and R. Plot compressed and stretched fibers of Fig. 4 shows the nature of actors and fur the load (pressure of the working fluid) from external sources by collector 12 and the pipes 11 a controlling influence on the compressed and stretched part of the Central plate 2 and side plates 3.

Work MACSIS in terms of the concentration of the load closer to the middle of the span will be paired with a concentration higher voltage here, as shown in Fig. 4. In order to discharge the design of a multiple piston set 9 provides smaller step between the pistons in the area of high stress concentration or by increasing the diameter of the piston 9 or the local increase of pressure in the piston 9.

Thus, the proposed design of multifunctional load-bearing element structures of buildings and structures provides high resistance load-bearing element with increasing external load static or variable.
