Abstract
The invention relates to a method of attaching a wire mesh sunshield screen to a building in which the screen is connected to the building by at least one traction element (119, 120, 121) and the screen is tensioned by exerting a traction on the traction element. The traction on the traction element is provided by a compression spring (30) and the intensity of the traction on the traction element is evaluated by an evaluation device (500, 501, 1550) comprising an opaque mask (1550) and a movable visual indicator (500, 501) which is movable relative to the opaque mask (550) as a function of the compression of the spring (30).
Claims14
A method for attaching a metal mesh sunshield screen to a building, the method comprising:
- connecting the screen to the building by at least one traction element connected to at least one edge of the screen,
- tensioning the screen by exerting a traction on the traction element, the traction element comprising a tie rod extending through an opening in a fastening element fixed to the building, the tie rod having, at a proximal end, a head connected to said edge of the screen, and, at a distal end, a tensioning nut screwed onto the tie rod, the traction on the traction element being provided by an elastically deformable compression spring extending around the tie rod and compression loaded between the fastening element fixed to the building and the tensioning nut, along a traction axis on the traction element, and
- evaluating the intensity of the traction exerted on the traction element by means of an evaluation device comprising:
- a first evaluation device element comprising a first bottom wall having a hole through which the tie rod extends, and a first envelope wall extending around the traction axis from the first bottom wall and surrounding a portion of the elastically deformable compression spring, the first bottom wall being clamped between the fastening element fixed to the building and a proximal end of the elastically deformable compression spring,
- and
- a second evaluation device element comprising a second bottom wall having a hole through which the tie rod extends, and a second envelope wall extending around the traction axis from the second bottom wall and surrounding a portion of the elastically deformable compression spring, the second bottom wall being clamped between the tensioning nut and a distal end of the elastically deformable compression spring,
- wherein said first and second evaluation device elements form a two-part housing surrounding the elastically deformable compression spring such that the envelope wall of one of the first or second evaluation device elements slides inside the envelope wall of the other and is progressively concealed by that envelope wall as the compression exerted on the elastically deformable compression spring by the tensioning nut increases,
- the evaluation device element that is progressively concealed forming a visual indicator, while the evaluation device element that conceals the visual indicator forms an opaque mask.

A device for attaching a metal mesh screen to a building through a fastening element fixed to the building, the device comprising:
- at least one traction element comprising a tie rod configured to extend through an opening in said fastening element fixed to the building, the tie rod comprising, at a proximal end, a head configured to be connected to at least one edge of the screen, and, at a distal end, a tensioning nut screwed onto the tie rod,
- an elastically deformable compression spring extending around the tie rod and configured to be compression loaded along a traction axis between said fastening element and the tensioning nut, to exert a traction on the tie rod, and
- an evaluation device comprising:
- a first evaluation device element having a first bottom wall with a hole through which the tie rod extends, and a first envelope wall extending around the traction axis from the first bottom wall and surrounding a portion of the compression spring, the first bottom wall being configured to be clamped between said fastening element and a proximal end of the elastically deformable compression spring, and
- a second evaluation device element having a second bottom wall with a hole through which the tie rod extends, and a second envelope wall extending around the traction axis from the second bottom wall and surrounding a portion of the compression spring, the second bottom wall being configured to be clamped between the tensioning nut and a distal portion of the compression spring,
- wherein said first and second evaluation device elements from a two-part housing surrounding the compression spring such that the envelope wall of one of the first or second evaluation device elements, in use, slides inside the envelope wall of the other and is progressively concealed by that envelope wall as the compression exerted on the compression spring by the tensioning nut increases, and
- wherein the evaluation device element that is progressively concealed forms a visual indicator, while the evaluation device element that conceals the visual indicator forms an opaque mask.
