Mould for the construction of a protection and securing element of the mattress type and relevant method
A mould for constructing a protection and securing element of the mattress type comprises an upper frame ( 10 ), a lower frame ( 30 ) and a plurality of dies engaged in the lower frame and particularly suitable during use for receiving cement material. The upper and lower frames are modular structures which each comprise a plurality of carrier elements which are selectively connected to each other, the number and/or length of the carrier elements being variable, during use, so as to vary the length and/or the width of the mould.
1. A mould for constructing a protection and securing element, the mould comprising an upper frame, a lower frame and a plurality of dies engaged in the lower frame and the upper frame, wherein the upper and lower frames are modular structures which each comprise a plurality of carrier elements which are selectively connected to each other, a number and/or length of the carrier elements being selected during use so as to vary a length and/or a width of the mould and an arrangement of the dies engaged with the lower frame and the upper frame, each of the dies comprising at least one die base, a lower die member and an upper die member, the lower die member and upper die member of each of the dies being fixed to the lower frame and the upper frame of the mould, respectively.
2. A mould according to claim 1 , wherein the plurality of carrier elements for each of the upper frame and the lower frame are arranged in parallel rows in a longitudinal direction and in parallel rows in a transverse direction so as to construct a grid-like configuration, the carrier elements being engaged with each other by joint members.
3. A mould according to claim 2 , wherein each of the upper frame and the lower frame comprises four sides formed by a first set of the plurality of carrier elements which are connected to each other at ends thereof by the joint members and forming a periphery thereof and a second set of the plurality of carrier elements which are arranged transversely and internally with respect to the carrier elements forming the periphery.
4. A mould according to claim 3 , wherein each of the carrier elements comprises one or more tubes which are connected to each other by the joint members.
5. A mould according to claim 4 , further comprising supports, the joint members of the carrier elements at corners of the periphery being selectively engaged with the supports.
6. A mould according to claim 5 , wherein each of the supports comprises a selective fixing element in order to allow adjustment, during use, of a height of each of the lower frame and the upper frame with respect to a ground.
7. A mould according to claim 6 , further comprising a base frame comprising at least four peripheral carrier base elements.
8. A mould according to claim 6 , further comprising a support structure which comprises at least two longitudinal members, in which there are selectively fitted a plurality of cross-members, to which the supports are connected.
9. A mould according to claim 8 , wherein the dies further comprise engagements formed on an outer surface thereof and which are engaged with the plurality of carrier elements.
10. A mould according to claim 1 , wherein each of the dies is a unitary structure.
