<p>The closure, consisting of a laminar body (4) of cardboard or similar material, has a configuration in accordance with that of the inter-beam arch (1) to which it is to be applied, being adapted at its perimeter to the inter-beam arch, and the closure (4) having the particular feature of originally having a height greater than that of the actual inter-beam arch (1) and being provided with perimeter stamping lines (5) at different heights, allowing it to be sectioned at any of them in order to adapt the closure (4) to the height of the inter-beam arch (1), closing specific cells (3) in the actual inter-beam arch in order to prevent the ingress of concrete when the latter is poured. Furthermore, the closure (4) has lateral flanges (6) that can be folded and, when the closure is mounted on the inter-beam arch (1), fold towards the inside of the respective cells (3), thereby immobilizing the closure with respect to the inter-beam arch. Optionally, this immobilization is achieved by means of clamps (9) that pass through pairs of windows (7) made in the lateral surface of the closure (4), which clamps (9), on account of their elasticity, apply a pressure to the corresponding partition (2) of the inter-beam arch (1) when the thickness of the partitions (2) coincides with the lath originating between each pair of windows (7).</p> |
