A retractable roof for a building having a supporting frame and a high structure extending vertically above the supporting frame. The roof has at least one structure section with first and second panels. The first panel is hingeably mounted on the supporting frame at a proximal hinge and the second panel is hingeably mounted on the first panel at a distal hinge. A distal end of the second panel is suspended to the high structure with a distal cable connected to a distal motorized winch. A tackle member connects to both first and second panels adjacent the proximal hinge and the distal end, respectively, and includes a tackle wire that forms a wire side of a triangular cross-sectional shape with the first and second panels. The tackle wire connects to a winch mechanism to control a length of the wire side.

Disclosed in the present invention is a cable dome structure using continuous ridge cables. A structure system includes n same plane trusses which are distributed in the radial direction and each consist of continuous cables and rods, the plane trusses being connected by means of k1 circles of hoop cables to form a stable whole. The cable dome structure consists of ridge cables, hoop cables and pressing rods. Each ridge cable starts from a lower joint of a pressing rod and sequentially passes through upper joints of outer side pressing rods, and all the ridge cables converge on a support joint. The ridge cables have overlaps. Upper joints of the pressing rods and inner side adjacent cables are fixedly connected, and lower joints of the pressing rods and the hoop cables are fixedly connected, the cables slidably passing through the joints.

Disclosed is a suspended ceiling system, a securing member, and process of installing a patterned suspended ceiling system. The suspended ceiling system includes a grid system having first members and second members, and at least one substrate which extends below the grid system. The at least one substrate has an exposed surface and a concealed surface, and the at least one substrate has first sides and second sides which extend between the exposed surface and the concealed surface. Securing members attach to the concealed surface proximate the first sides, and the securing members have grid engagement members which secure the at least one substrate to the grid system. The securing members cooperate with the first members and the second members of the grid system to properly position the substrate and the spacing between adjacent at least one substrates is controlled.

Removable roofing system comprising a motor inserted inside a drum (2), a cord, a compensation device (4), two rigging rails (5a, 5b), at least one guide arch (6a) and removable roofing, the at least one guide arch (6a) being connected to the cord and to the removable roofing, and being designed so that each of its ends slides in a rigging rail (5a, 5b), the cord passing along each rigging rail (5a, 5b) and through the compensation device (4) and being connected at its two ends to the drum (2) so that the rotating of the drum (2) by the motor causes the cord to move in a direction dependent on the direction of rotation of the drum (2), deploying or retracting the removable roofing by moving the at least one guide arch (6a), each rigging rail (5a, 5b) being equipped with at least one end pulley (21a, 21b) and with at least two corner-block deflecting pulleys (20a, 20b, 23a, 23b) which are designed to guide the cord from the compensation device towards the at least one end pulley (21a, 21b), and the compensation device (4) is designed to automatically compensate for variations in cord tension.

A roof construction for a canopy is disclosed. The roof construction is provided with two beams making an angle with each other, each having an inner side and an outer side; a corner piece positioned between the beams, which corner piece has an inner side and an outer side; and a LED strip light that extends substantially continuously over the outer side of said corner piece and over the outer side of at least a part of each of said beams. The provision of a LED strip light on the outer side of the roof construction offers an additional option for providing lighting for a canopy.
