[0022] Embodiment

[0023] The first embodiment of the present application provides a flexible membrane sunshade cable-strut grid frame, which comprises a membrane main body 8, a unidirectional or multidirectional replicated tension variable two-bar structural unit. The tension variable two-bar structural unit is a flexible base material, which has good flexibility and ductility. The tension variable two-bar structural unit comprises an upper chord bar assembly 1 and a lower chord bar assembly 2. An adjustable length connecting rod 3 is connected between the upper chord bar assembly 1 and the lower chord bar assembly 2. Figure 1 It can be known that the upper chord bar assembly 1 corresponds to the inside of the sunshade cable-strut grid frame after the length of the connecting rod 3 is adjusted for sunshade, and the lower chord bar assembly 2 corresponds to the outside of the sunshade cable-strut grid frame after the length of the connecting rod 3 is adjusted for sunshade.

[0024] Further, the membrane main body 8 is attached to the tension variable two-bar structural unit and changes with the change of the shape of the tension variable two-bar structural unit. Specifically, the tension variable two-bar structural unit is adjusted to different shapes with the change of the length of the connecting rod 3, and finally the membrane main body 8 is adjusted to various sunshade shapes. The present application innovatively combines a new type of cable-strut grid hybrid roof truss structure with the whole tension variable two-bar structural unit, unidirectional or multidirectional replication arrangement, which has rich structural expression. Not only can it realize sunshade, but also can be adjusted to various sunshade shapes without increasing materials, which improves the problem that the existing sunshade structure usually adopts truss and rigid frame as support frame, which makes the overall performance of the sunshade structure single and cannot meet the customer's demand to change into multiple shapes, and increases the amount of materials consumed.

[0025] In combination Figure 2The upper chord assembly 1 and the lower chord assembly 2 each comprise three struts, one end of the three struts is in contact to form a node 9, and the connecting rod 3 is connected between the two nodes 9. The three struts of the upper chord assembly 1 and the three struts of the lower chord assembly 2 form six edges of a parallelepiped, and the connecting rod 3 is one of the diagonal lines of the parallelepiped, which is simple in structure and convenient for installation and construction when the length of the connecting rod 3 is adjusted.

[0026] Further, the steel cable 4 is further included, and the steel cable 4 forms another six edges of the parallelepiped. The connecting rods 3 in the plurality of parallelepipeds are parallel, and the parallel arrangement of the connecting rods 3 facilitates the uniform adjustment of the shape of the plurality of tensile variable two-bar structure units.

[0027] In combination Figure 3 , each two adjacent edges of the parallelepiped are attached with a triangular membrane body 8; each face of the parallelepiped has two triangular membrane bodies 8. The two triangular membrane bodies 8 on the same face of the parallelepiped are connected by a ventilation gap 7, and the size of the ventilation gap 7 is adjustable according to the adjustment of the shape of the tensile variable two-bar structure unit, which is highly adaptive, so that the whole presents a breathing type ventilation skin. Meanwhile, the membrane body 8 can also be in other shapes and can be cut into various flower shapes according to requirements.

[0028] Further, the membrane body 8 is a flexible solar photovoltaic membrane, or is combined with a flexible sunshade membrane, and various membrane combination modes are adopted to form a comprehensive application of color and function. The use of the flexible solar photovoltaic membrane enables the integration of sunshade, photovoltaic energy storage and structure, and maximizes the low-carbon green energy-saving effect of the sunshade tensile net rack. When the length of the connecting rod 3 is adjusted, the membrane body 8 inside the sunshade tensile net rack is an upper membrane 5, and the membrane body 8 outside the sunshade tensile net rack is a lower membrane 6, so that the indoor space is maintained, and a better sunshade effect is achieved.
