CLAMP FOR HOLDING AND DISPLACEMENT OF STRUCTURES
ES2913575. Patente Request: ES202031202
The present invention deals with a clamp for clamping and moving structures, which has a very low cost, can be used for profiled beams of different cross-sections and does not require additional energy or drive mechanism. The clamp comprises a support, a body, a cradle supported with the possibility of longitudinal sliding on a lower inner face of the body and a compressible spring provided of a first end attached to the cradle and a second end attached to the lateral face that in a rest position retains the cradle in the vicinity of the lower end and in a retention situation in which the body embraces the structure the cradle moves towards the upper end, the spring is compressed and the structure is retained.
The present invention has applications in the construction and civil engineering works sector, providing a much simpler solution and with much lower associated costs than those currently used. Devices for holding and causing the displacement of structures are known, for example in the construction of pushed bridges. Cables, hydraulic jacks, prestressing cable jacks, hydraulically actuated cleats, chains, or hydraulic jack assemblies are commonly used to push heavy structures. However, these solutions are highly complex and associated with a high cost, they can also produce local buckling effects in the structures and require additional energy to perform the wedging or retention of the structures. Our invention solves these drawbacks and provides a much simpler, cheaper and more effective solution.
