Abstract
An expansion joint (1) for a concrete slab formwork system, said joint comprising first and second longitudinal elements (2, 3), arranged side-by-side in the same horizontal plane, and intended to each form an integral part with an upper and horizontal edge of a concrete slab, the first and second longitudinal elements (2, 3) comprise arrangements (5, 6, 7) opening on their upper horizontal walls and enabling at least a portion (2a, 3a) of each of the first and second longitudinal elements (2, 3) to be withdrawn for replacement thereof. The first longitudinal element (2) comprises a stack of three layers of material (2a, 2b, 2c), with an intermediate layer (2b) having a smaller width than that of the two other layers (2a, 2c) such that the first longitudinal element (2) has a U-shaped cross-section, and the second longitudinal element (3) comprises a stack of three complementary layers of material (3a, 3b, 3c), with an intermediate layer (3b) having a larger width than that of the two other layers (3a, 3c) so as to form a transverse projection that is able to fit in the recess of the U-shape of the first longitudinal element (2).

Abstract
The formwork comprises first and second horizontal support bases shaped and arranged to have a plurality of projecting forms and cut-outs capable of intermeshing by means of engagement, said support bases receiving rods forming concrete sockets. The first horizontal support base (1) receives, for attachment, first pairs of brackets (4a) (4b) arranged and spaced apart having a vertical branch allowing the height-adjustable attachment of a vertical plate (5) forming a height-adjustment system. Said second support base (2) is arranged with second pairs of brackets (8a) (8b) arranged opposite said first pairs of brackets, being arranged attached to said second support base. Said second pairs of brackets allow, by means of the vertical branches thereof, the attachment of a fixed-position vertical counterplate (9). The plate (5) is arranged on the length thereof with oblong holes (5a) established on one portion of the length thereof, and the counterplate (9) has openings (9a) for the inclusion of a means (6) in the form of a bolt for adjusting and attaching the plate in relation to the counterplate.
