Patent ID: 8511026

Claim:
Drywall construction system, comprising: a load-bearing structure, and large-surface flat construction elements which have joining pieces, and anchoring pieces fixing the joining pieces of the construction elements to the load-bearing structure; wherein the anchoring pieces comprise: fixed profiles which have female elements forming holes, said fixed profiles are fixed to the load-bearing structure, and sliding profiles equal in number to the fixed profiles, each one of the sliding profiles being longitudinally mounted on one of the fixed profiles such that the sliding profile is movable along the fixed profile and provided with openings, the openings coinciding in number and position with the holes of the fixed profiles, each one of the openings has two contours with different widths, the two contours being consecutively located in a movement direction of the sliding profiles; and wherein the joining pieces of the construction elements have male elements, the male elements coinciding in number and separation with the openings of the sliding profiles and holes of the fixed profiles, the male elements have formations which can be inserted through a wider contour of the openings and retained by a narrower contour of the openings, said male elements being accessible through a rear of the construction elements for insertion through said openings and through windows; and wherein the sliding profiles can be longitudinally slid with respect to the fixed profiles between an inactive position, in which the wider contour of the openings of the sliding profiles faces the holes of the fixed profiles, allowing passage of the male elements of the joining pieces of the construction elements through said openings and holes, and a retention position, in which the narrower contour of the openings faces the holes and covers over the formations of the male elements preventing release of said formations.
