Form traveller for the construction of engineering works
The invention relates to a traveller (1) for the construction of engineering works, comprising two structures, namely: a securing structure (2) for securing to the already built engineering work, and a working structure (3) on which construction of the work advances. The traveller is characterized in that the securing structure (2) comprises: a first end ring (6) and a second middle ring (7), both of said rings (6, 7) being coupled to the periphery of the section (27) of the already built work; at least one transom bar (9) that joins the end ring (6) and the middle ring (7) on the side of the carriage (1); and connecting elements between the end ring (6) and the middle ring (7). The working structure (3) comprises exterior formwork (25) and floor formwork (23).
The invention relates to a self-launching falsework for platforms in ports, comprising a movable structure (1) that includes forms (2) and is supported by piles (3). The movable structure (1) rests on the piles (3) by means of at least two supporting devices (5) and each supporting device (5) comprises a front supporting girder (6d) including at least two coupling parts (18), a rear supporting girder (6t) including at least two coupling parts (18) and a lattice structure (7) below each supporting girder (6d, 6t). The two supporting girders (6d, 6t) are connected to one another by means of the at least two coupling parts (18) and this connection ensures that the supporting device (5) remains secured to the pile (3). Each supporting girder (6d, 6t) is joined to the movable structure (1) by means of at least two vertical coupling bars (8).
The wedging system for transmitting loads from formwork to the surrounding earth comprises a supporting member (3), a threaded bar (2) for the transmission of vertical load, a nut (11), and a base (1) that in turn comprises a plate (9) with a perforation (10), wherein the bar (2) for transmitting vertical load is secured to the supporting member (3), the supporting member (3) being affixed to a side wall of the formwork and the forces generated in the formwork being transmitted to the soil, thereby preventing relative movement between the base (1) and the supporting member (3), by means of the insertion of the bar (2) for transmitting vertical load into the perforation (10) in the plate (9) of the base (1) and screwing the nut (11) onto the upper end of the bar (2) for transmitting vertical load.
The invention relates to a traveller (1) for the construction of engineering works, comprising two structures, namely: a structure (2) for securing to the already formed engineering work, and a working structure (3) on which construction of the work advances. The traveller is characterised in that the securing structure (2) comprises: a first end ring (6) and a second middle ring (7), both of said rings (6, 7) being coupled to the periphery of the section (27) of the already formed work; at least one transom bar (9) that joins the end ring (6) and the middle ring (7) on the side of the carriage (1); and connecting elements between the end ring (6) and the middle ring (7). The working structure (3) comprises exterior formwork (25) and floor formwork (23), in which the securing structure (2) and the working structure (3) are joined at the lower part thereof by a main load-bearing girder (10, 10') and at the upper part thereof by the forward tracks (18, 18').
Buoyant modular device for the construction of platforms in ports, which comprises a base structure (1) receiving the concrete mass (35), a reinforcement structure (2) that supports the base structure (1), inflatable active floats (5) for raising and lowering the base structure (1)/reinforcement structure (2) assembly, passive floats (4) for maintaining the base structure (1)/reinforcement structure (2) assembly, and mechanisms (3) for anchoring the reinforcement structure (2) to a static base (6). Depending on the relative position of the base structure (1) and the reinforcement structure (2), in accordance with the configuration of the base structure (1), the configuration of the reinforcement structure (2), the number and position of the floats (both active (4) and passive (5)), and in accordance with the configuration of the mechanisms (3) for anchoring to the static base (6), there are four different embodiments of this device.
The invention relates to a clamp for handling large loads. The load to be held is a prismatic block, which may be spherical or irregular and is held by the clamp at three points. The clamp has a master arm (7) which is connected by means of at least one shaft to two free arms (3), with support elements (2) which improve grip being present at both the holding end of the master arm (7) and at the holding ends of the free arms (3).
