Embodiment Construction

[0016] figure 1 The proposed method is shown, which is expected to display the building structure scheme 1, and, by operator's choice, its separated blocks (component A) with the resulting loads and their comparison with the design values. Assembly A includes struts 2 and beams 3 . Component A is equipped with autonomous devices that control the load-carrying capacity and rigidity of the structure 4 . This device is connected to the reinforcement 5 of the beam 3 and to the strain-measuring transducer 6 .

[0017] figure 2 A block diagram of a building structure monitoring system comprising a device 7 for controlling the load bearing capacity is presented. Each device has a device 8 at the stiffener for determining an electrical or magnetic parameter. It can be, for example, a voltmeter or a resistance meter and a current source, the comparison block 9 has an input for connecting a strain-measurement sensor and can be used to compare:

Abstract

The invention is used for building and construction monitoring, in particular for monitoring the stress and strain state of a building steel cable roof and floors. Each rod of the cable reinforcementis pre-calibrated for tensile stress and electric resistance. During construction and the use of the building when the roof or the floor is loaded, low-frequency electric current is supplied to each stressed rod of the cable reinforcement and the electrical resistance of the rod is checked, thereby making it possible to determine the stress state of the rod. The maximum allowable resistance of therod being reached, the roof or floor loading capability is determined and the operational hazard of a building or construction is signaled.

Description

technical field [0001] The invention relates to the field of controlling (inspecting) developed building structures. Background technique [0002] One of the problems encountered when inspecting buildings is how to obtain adequate, reliable and timely data on the condition of the overall structures as well as their discrete elements. The problem and a solution to it have been described, for example, in the article "Monitoring of buildings and structures" by S.V. Nikolaev et al., and in January 10, 2007 The IV International Scientific-Practical Conference "Modern systems and devices of the complex security and fire protection of construction" (the IV international Scientific-Practical Conference "Modern systems and devices of the complex security and fire protection of construction objects, "Stroibezopasnost-2006") are described. [0003] This type of monitoring of building structures is also known from Russian Federation Patent #2250444 dated January 10, 2004 and US Patent...
