Abstract

A repair element for a formwork board that includes a housing. The repairing element comprising a first member made of thermoplastic material and a second member made of porous material, wherein the second member acts as a support of the first member, the first member being arranged on the second member. The first member has a height that partially projects from the board once the repairing element is fixed in the housing, the first member being suitable for filling a cavity existing between the repairing element and the housing once the repairing element is placed in the housing after being at least partially melted, thus sealing the attachment between the repairing element and the board. Repairing method of the board with the repairing element.

Abstract

A self-climbing scaffold system that includes rails and shoes fixed to concrete sections of a building that are adapted for guiding the rail in a climbing direction Z. The system further includes a guide element pivotally coupled to the rail, the guide element having at least a first guide surface which, in a prior position before a threading position for threading the rail, projects with respect to the rail towards a corresponding concrete section. The first guide surface is adapted for interfacing with the shoe in said prior position and straightening the rail with respect to the shoe as said first guide surface moves in a guided manner in the shoe pivoting with respect to the rail.
