- Such a formwork 4 is intended to pour concrete to obtain a reinforced concrete.
- the support comprises two housings 11, arranged between two formwork portions 4 and delimited laterally by the longitudinal members 2, and longitudinally by two end cross members 6 of the two adjacent formwork.
- the cross members 6 delimiting such a housing 11 have a U-shaped section, having a vertical wall and two horizontal flanges at the upper and lower ends of the vertical wall.
- the two crosspieces 6 delimiting the housing 11 are arranged parallel to each other and so that the horizontal flanges are oriented towards the interior of the housing 11.
- a sensor 13 is disposed in each housing 11.
- the sensor 13 is substantially cylindrical in shape. According to one variant, the sensor is of rectangular shape.
- the sensor 13 comprises a lower part and an upper part, the weighing measurement being performed by measuring the stress or the relative movement between these two parts.
- the upper part of the sensor 13 comes to bear on a plate 14 bearing against the upper horizontal edges of two cross members 6 delimiting the housing 11.
- the lower part of the sensor 13 is integral with a plate 15 which is clamped to the support by clamping means disposed under the housing 11 and constituted by screws 16 cooperating with an orifice formed in the horizontal rim of a cross member 6 delimiting the 11 of the sensor housing 13.
- the clamping means are intended to make the sensor 13 secured to the support during transport of a member 1 of the workshop to the site of the installation to avoid any degradation of its function and preserve the calibration performed.
- Each of the elements 1 illustrated in FIG. 2 comprises at least two sensors 13.
- the two sensors 13 of each element 1 are positioned in an aligned manner in the longitudinal direction of the support.
- Each element 1 comprises on the surface of the vertical wall of each spar 2 facing outwardly of the support means of attachment.
- the longitudinal members 2 comprise fixing holes 17 for screws. These holes are formed at the vertical wall of the longitudinal members 2, so as to open on their outer surface.
