CLAMP FOR HOLDING AND DISPLACEMENT OF STRUCTURES

In the construction of roads and bridges, it is common for a large structure to be moved on several beams to a desired position, where by structure is meant any solid element or composite structure of a building or bridge, which is to be moved. Normally the displacement is done by means of hydraulic jacks or pushing and lifting machinery and the structure is supported by various devices installed on the beams using systems made up of rollers or bearings. Specifically, in the construction of launched bridges, the use of rollers for the support and movement of structures is common. However, the machining required by these systems is very expensive. Systems made up of large wheels, track systems or chains are very expensive and have many components in friction, so the net skid resistance is very high. It is also usual that, by having several support points, the support surface that contacts the structure does not contact completely and/or uniformly in all the supports and the loads are unbalanced, since the structure does not support in the same way in all props. The solutions described in the state of the art are either very expensive, since they require continuous labor and replacement of pads, or they have a very high coefficient of friction. The use of the device reduces the friction of the structures with the pillars, avoids the continuous use of labor and reduces the cost associated with the replacement of support elements such as pads.
