Background technology
At present, due to the high-ductility of steel and toughness and its excellent wind resistance anti-seismic performance.Steel construction is just widely used in the fields such as industrial premises, executive information systems, residential houses, large public building, railroad bridge, offshore platform as a kind of novel energy-conserving and environment-protective building system.But due to the anti-corrosion property the subject of knowledge and the object of knowledge limit of steel own, therefore among its Long-Time Service, especially can produce certain distortion for large for formed steel construction framework, then can cause caving in of steel structure body when deforming more than corresponding limit, causing casualties and property loss.Therefore, the deformation monitoring for early stage steel structure body seems particularly important.At present, the main flow plant quarantine that steel construction adopts is single, is generally to utilize surveying and mapping technology carry out corresponding geometric distortion monitoring or utilize information network to form the digitized monitoring system of a set of complexity.In the process come into operation the former due to its general field work amount large, be subject to operation side interference, and can not meet and dynamically wait technical requirement continuously and can not extensively be promoted.Accordingly, for the digitized monitoring system of complete set, because steel construction shortterm deflection is less, therefore, it comes into operation costly on a large scale for a long time, and economic benefit is lower, and its installation monitoring facilities is comparatively complicated, needs to be equipped with the personnel with corresponding professional knowledge and carry out monitoring management.Monitoring cost is higher.
Summary of the invention
In order to improve above-mentioned situation, a kind of steel construction stress of the utility model prior-warning device provides one and is arranged on steel structure node place, utilize lever principle by steel structure node place carry out the device of early warning by Amplification.Structure is simple, easy to use.Greatly reduce the cost of steel construction deformation monitoring.
A kind of steel construction stress of the utility model prior-warning device is achieved in that a kind of steel construction stress of the utility model prior-warning device is made up of subject support means, circuit triggers part and lever Amplification device.Subject support means is made up of pressure base plate, connecting hole, pressure survey bar, connecting bushing, double layer sleeve barrel, bearing plate and three corner steadies.The triangle place of three corner steadies is evenly placed in bottom bearing plate, and connecting hole is placed in above bearing plate.Three corner steady tops are connected with pressure survey bar one end by connecting bushing, and the other end of pressure survey bar is vertically placed in pressure base plate center, and described pressure survey bar bending can be out of shape or break after stressed, preferably bending distortion.Double layer sleeve barrel is placed on pressure base plate.Lever Amplification device is made up of limited support groove, conduction lever, metal contact piece, support conducting rod and Compress Spring.Supporting conducting rod one end is vertically placed on pressure base plate, limited support groove is placed in and supports the conducting rod other end, conduction lever one end and connecting bushing are socketed, the other end is connected with metal contact piece through limited support groove, distance between described limited support groove and connecting bushing, is less than the distance between metal contact piece.Described limited support groove conduction.Compress Spring one end is placed on pressure base plate, and the other end connects between conduction lever and metal contact piece, and circuit triggers part is made up of early-warning lamp, wire, L shape contact and accumulator.Accumulator is placed on pressure base plate, and be connected with support conducting rod by wire, L shape contact one end is vertically placed on pressure base plate, the other end is positioned at directly over the metal contact piece of conduction lever one end, early-warning lamp is placed between double layer sleeve barrel, early-warning lamp is connected with accumulator by wire, and is connected with L shape contact by wire.Preferably transparent acrylic material outside described double layer sleeve barrel.
During use, be placed in the easily deformable place in steel structure node place, particularly steel construction by device level.Then fixed by the connecting hole above bearing plate, steel structure frame produces distortion, apply pressure to bearing plate, produce toward downforce bearing plate, STRESS VARIATION is passed to pressure survey bar by three corner steadies by bearing plate, after pressure survey bar is stressed, bending distortion or stressedly to fracture, now three corner steady tops are pressed down by connecting bushing band moving conductive lever one end, utilize lever principle, the conduction lever other end is up moved, and metal contact piece produces displacement upwards.When displacement is greater than certain limit, metal contact piece and L shape contact pad, now accumulator, by the limited support groove of conductive supporting bar, conduction and metal contact piece and L shape contact, form circuit pathways, early-warning lamp lights between double layer sleeve barrel.Utilize lever principle by steel structure node place carry out the object of early warning by Amplification.
Beneficial effect
One, structure is simple, convenient and practical.
Two, with low cost, be easy to promote.
