The present invention relates to a centring on which a formwork is supported for the construction of platforms in ports, where the centring is a movable centring, so that it makes the formwork advance without the need for other auxiliary structures.
The invention is applicable to the construction of civil works, more specifically to the construction of port platforms, which stand on piles installed in the seabed.
Formwork supporting structures where the concrete is in turn poured are employed in the construction of port platforms.
Supporting structures are currently placed hanging or held by means of a second structure placed above the supporting structure, to hang this structure it is necessary to install a series of braces and beams along the length of the platform.
In the state of the art, document GB 1509440 A is known, disclosing a mobile formwork for the construction of bridges. Said formwork is supported on jacks, during the concreting, and on rollers, which are employed to move the formwork to the next concreting position. In this document, the jacks as well as the rollers are supported on pier caps fixed to the piers of the bridge.
Likewise, in the state of the art, the document ES 2387208 A1 is known, whose holder is the same as that of the present application, and which discloses a shuttle device whose features are similar to the device disclosed in the present patent application. In this device, in order to remove the formwork, it is necessary for an operator to get under the aforementioned formwork, thus when the water level is high, this impedes carrying out said operation, or at best, makes it more difficult and slows it down.
The construction of the platforms is carried out sequentially, in such a way that once the concrete has gained resistance and has hardened, the formwork supporting the structure is moved to a new position for a new concrete pouring and to repeat this process until the construction of the platform is complete.
The invention described discloses a movable centring for platforms in ports, which comprises a mobile structure comprising in turn various formworks and that is supported on piles.
The support of the mobile structure on the piles is achieved by means of, at least, two supporting devices. Each supporting device comprises:
The two supporting beams are joined together by means of, the at least two coupling pieces, thus leaving the supporting device fixed to the pile by means of this union. Each supporting beam is joined to the mobile structure by means of, at least, two vertical latching bars.
The front supporting beam comprises supporting plates and advance rollers, and the rear supporting beam comprises fixed supporting plates, in such a way that the mobile structure is supported on the supporting plates of the two supporting beams, when the mobile structure is in the static position, and is supported on the advance rollers of the front supporting beam during the movement of said mobile structure, the rear supporting beam having been lowered in relation to the static position by means of the vertical latching bars.
In the movable centring for platforms in ports, the supporting beams comprise at least two nuts into which the vertical latching bars are screwed, in such a way that the supporting beams move in a vertical direction by means of a rotating movement of the vertical latching bars.
In the movable centring for platforms in ports, the coupling pieces reproduce at least partially the external geometry of the pile, so two opposite coupling pieces are joined together by means of tying bars, fixing the supporting beams to the piles.
In the movable centring for platforms in ports, the coupling pieces comprise threaded holes into which the tying bars are introduced, which block their relative movement by means of nuts.
In the movable centring for platforms in ports, the advance rollers comprise a height regulation mechanism. Said height regulation mechanism comprises: a track, at the end of which the advance roller is located, a threaded hole located at the front supporting beam, a threaded bar joined to the track at one of its ends and which is introduced into a threaded hole of the front supporting beam.
The track is blocked by screwing a nut onto the end of the threaded bar which passes through the threaded hole.
In the movable centring for platforms in ports, the mobile structure comprises pairs of longitudinal beams brought together by means of a group of trusses, which make the mobile structure rigid. Said longitudinal beams lean against the supporting plates, in the static position of the mobile structure, or against the advance rollers during the movement of the aforementioned mobile structure.
To complete the description and with the aim of helping to achieve a better comprehension of the characteristics of the centring, a series of figures accompany this specification, wherein with illustrative and non-limitative character, the following has been represented:
Next, a list with the numerical references used in the figures is provided, which show the centring, which is the object of the invention:

As it has already been pointed out, and as can be observed in the figures, the centring which is the object of the invention (observable in
Each supporting device (5) comprises:
Each supporting beam (6d, 6t) comprises:
The front supporting beams (6d) comprise in addition to the aforementioned elements, advance rollers (9) located next to the supporting plates (4). In the case of the front supporting beams (6d), the supporting plates (4) are removable.
The coupling pieces (18) are pieces which reproduce at least partially the external geometry of the pile (3), thus two opposite coupling pieces (18) are joined together, and fix the supporting beams (6d, 6t), of which they are part, to the pile (3), thus constituting a supporting device (5) for the various formworks (2).
Two opposite coupling pieces (18) fix their relative position by means of nuts (11b) screwed into tying bars (10), said tying bars (10) passing through threaded holes (12) comprised by the coupling pieces (18).
Therefore, by fixing the coupling pieces (18) together it is possible in each pair of piles (3) to establish a supporting device (5) made up by two supporting beams (6), on which the mobile structure (1) is supported by means of the supporting plates (4) in static position or by means of the rollers (9) during the movement of the mobile structure (1).
With the mobile structure (1) supported on the supporting plates (4) of the supporting beams (6d, 6t), that is to say in static position, the concreting of a section of the platform is carried out.
To remove the formwork, in the preferred embodiment of the movable centring, a method is employed which comprises at least:
The advance rollers (9), in the preferred embodiment of the invention, comprise a height regulation mechanism (observable in
The height regulation mechanism of the advance rollers (9) comprises:
The regulation of the height of the advance rollers (9) is carried out by blocking the relative position of the track (13) with regard to the front supporting beam (6d), by screwing a nut (11c) onto the end of the threaded bar (14) which passes through the through hole (17).
The mobile structure (1) comprises pairs of longitudinal beams (15) brought together by means of a group of trusses (16) which make the mobile structure (1) rigid, in such a way that such longitudinal beams (15) lean against either the supporting plates (4) or the advance rollers (9), as the case may be at that moment, said longitudinal beams (15) leaning against supporting devices (5) located at two adjacent alignments of piles (3).
