20080197278 | Device for detecting position of steel bar in structure and method thereof - Gamma rays, X-rays or ionizing irradiations from two radiation sources penetrate through a steel bar in a reinforced concrete structure. Images of the steel bar are thus projected on two films. Through geometric relationships between the images and the steel bar itself, thicknesses between the steel bar and surfaces of the reinforced concrete structure are obtained. The position of the steel bar obtained according to the present invention is reliable and accurate. And the data obtained can be used for structure safety. | 08-21-2008 |
20080198962 | Device for measuring size of steel bar in structure and method thereof - A gamma ray, an X-ray or an ionizing irradiation penetrates through a steel bar in a reinforced concrete structure. An image of the steel bar is thus projected on a film. Through geometric relationships between the image and the steel bar itself, the size of the steel bar is calculated. The size of the steel bar obtained according to the present invention is reliable and accurate. And the data obtained can be used for structure safety. | 08-21-2008 |

20140284532 | BRIDGE LIFTING SUPPORT BRACKET - A bridge lifting support bracket is disclosed, which comprises a supporting mechanism, comprising a bracket having a depressed area at a face thereof and a raising portion disposed at two sides of the bracket, respectively; and at least two jacks, disposed on a bottom face of the raising portions, respectively. As such, a space for receiving a jack properly is secured by digging out a space of a concrete protection layer of a lower structure and using a supporting mechanism cooperating therewith when only a small space or a closely tight bonding with no seam existing between a bridge and a pier, whereby a raising process of the bridge may be safely performed. | 09-25-2014 |
20140306169 | THIN JACK DEVICE FOR BRIDGE LIFTING - A thin jack device for bridge lifting is disclosed, comprising a base seat; a lifting unit, movably connected with the base seat; and a displacement sensor, disposed at a side of the base seat. In this manner, an arrangement may be applied when a gap altitude between a bridge girder and a pier is insufficient to reduce a risk possibility of violation of the bridge and pier, and a displacement sensors attached to stroke is used to monitor a raised altitude to reduce a mechanical error to promote safety and thereby sufficiently the current pier structure to save a temporarily used pier or a frame based design and construction, whereby increasing the construction safety and decreasing the construction cost. | 10-16-2014 |

20140309767 | SYCHRONOUS CONTROL INTEGRATED SYSTEM FOR BRIDGE LIFTING - A synchronous control integrated system for bridge lifting, comprising a monitor mechanism; an oil pressure control mechanism, connected to the monitor mechanism; a plurality of jacks, each connected to the oil pressure mechanism, respectively; and a sensor mechanism, connected to the monitor mechanism. As such, a shift variance generated by girders of a bridge may form a signal by using a sensor mechanism and jacks together transmitted on line to a monitor mechanism as a control parameter, so that the monitor mechanism may have an accurate adjustment and monitoring on an oil pressure control mechanism and the jacks, whereby completing the synchronous control operation for the bridge lifting course. Furthermore, the bridge lifting construction may have its improved accuracy and safety. | 10-16-2014 |
