Description
Technical field
The present invention relates to building zero-deformation intelligent control system in the technical field of civil engineering.
Background technology
Traditional civil engineering structure; along with the influence of variation, the increase of tenure of use and other unpredictable factor of external environment, usually can cause floor distortion even fracture, the serviceable life of influence building; and cause hidden danger to a certain extent, bring spirit panic to the user.General processing means commonly used are: transform, reinforce or push over reconstruction.And so a series of processes on the one hand will spend very high economic cost, on the other hand the strengthening reconstruction cycle longer, the occupant mostly needs resettlement, brings the inconvenience of work life thus.How just can make building structure be in controlled, best stress, and at any time distortion is adjusted into zero, be the problem that researchers are thinking deeply always.
Summary of the invention
For overcoming above-mentioned shortcoming, the invention discloses a kind of building zero-deformation intelligent control system, the key of this design concept is: with intelligence control system and drive system applications in building structure, and according to the internal force state of actual conditions regulation and control agent structure, the distortion of control agent structure makes it be in a kind of " zero distortion " state all the time.The technical scheme that adopts is: monitor is installed on building structure, the deformation, the internal force status information that record are fed back to intelligence control system, after the analyzing and processing of intelligence control system to information, send instruction in good time, commander's drive unit applies driving force to drive force source, and drive force source adopts the new-type functional material marmem.This driving material a series of except having " S " behavioral trait, as selection function (Selectivity), self-diagnosing function (Self-diagnosis), self-regulating function (Self-tuning), self-recovery function (Self-recovery), self-regeneration function (Self-repair), sensitivity (Sensitivity), outside the permanance (Survivability) etc., also has the common metal of being different from properties of materials simultaneously, as SME (Shape Memory Effect, be called for short SME), phase transformation super-elasticity (Super-Elasticity, be called for short SE) and pseudoelasticity performance (Pseudo-elasticity is called for short PE), elastic modulus temperature variation characteristic and high damping characteristic etc.By drive unit (adjustable direct supply, vapours etc.) marmem is driven excitation, and utilize temperature measuring equipment that the temperature of drive force source is monitored, when reaching design temperature, intelligence control system is initiatively closed drive unit, utilize its material behavior, mainly be SME and phase transformation super-elasticity pseudoelasticity performance, make it under limited recoil state, produce powerful restoring force, utilize the force-bearing situation of this restoring force change agent structure, and the distortion of control agent structure makes it be in a kind of " zero distortion " state all the time.
Building zero-deformation intelligent control system comprises agent structure, is connected with drive system and intelligence control system on agent structure;
Drive system comprises drive force source, drive unit, thermal resistance sheet, temperature measuring set, intelligent anchoring device; Drive force source is arranged in the external of agent structure, two ends are by intelligent anchoring device and agent structure anchoring, and drive unit forms a closed-loop path by lead and drive force source, are used to realize the driving to drive force source, the thermal resistance sheet is fixed on the drive force source, is connected with temperature measuring set;
Intelligence control system comprises stress monitor, computer control system, the stress monitor is installed in the control section of agent structure, the machine control system is connected with drive system as calculated, formation close and control loop, computing machine is by analyzing and processing and transmission to being subjected to force information, and commander's drive system is moving and non-moving.
Agent structure can be a prestressed structure, also can be non-prestressed structure.
Drive force source adopts marmem, and its shape can be straight line, broken line or curve.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in detail.
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is structural representations of the embodiment of the invention;

Embodiment
The agent structure 1 of present embodiment is the non-prestressed concrete free beam, the size of main body of beam is 2000mm * 100mm * 200mm, the shape-memory alloy wire of φ 5 is carried out prestretched to initial prestrain ε 0=(5-6) %, it is external to be arranged in beam by two steering block 10 broken lines, two ends are by intelligent anchoring device 7 and agent structure 1 anchoring, drive unit 5 adopts adjustable direct supply, and stress monitor 8 adopts intelligence sensor, and 2 colligations of thermal resistance sheet are on shape-memory alloy wire.Carry out 2 loadings at span centre at a distance of the 400mm place, intelligence sensor passes to computer control system 9 with load information, carry out the data computation analysis by computer control system 9, after the crack appears in the tensile region that is loaded on beam, stop to load and keeping load, then by computer control system 9, marmem is implemented the energising excitation, and slowly unloading, make load remain at loading level place, record the temperature of shape-memory alloy wire simultaneously by thermal resistance sheet 2 usefulness temperature measuring sets 6, make it reach phase transformation end temp A
fMore than, after this continue energising a period of time.In galvanization, the crack of distortion of the span centre of continuous detecting beam body and tensile region.The characteristics of this example are to utilize the material behavior of marmem, mainly be SME and phase transformation super-elasticity pseudoelasticity performance, make its powerful restoring force that phase transformation produces under limited recoil state, utilize the stress of this restoring force change agent structure, and the distortion of control agent structure control section makes it be in a kind of " zero distortion " state all the time.The result shows that the span centre distortion of beam reverts to zero substantially, and the crack of tensile region is also closed substantially.
The present invention is simple in structure, easy to operate, to building deformation control accurately, can prolong the serviceable life of buildings, and the repairing work that also can be building structure in the hole gains time.
