[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] like Figure 1-Figure 5As shown, an embodiment of the present invention provides an umbrella-shaped supporting cable membrane structure, which includes a membrane support frame 1, a sleeve 2, a middle rod 4, a flexible membrane 6, a plurality of lower cables 3 and a plurality of upper cables 5. The membrane support frame 1 is arranged on the main structure 100, and the membrane support frame 1 is provided with a plurality of connection nodes 11 distributed around its center. The plurality of lower cables 3 are circumferentially distributed on the outer wall of the sleeve 2, and one end of each lower cable 3 is connected to the connection node 11, and the other end is connected to the sleeve 2, so that the sleeve 2 is suspended, and due to the action of gravity, the sleeve 2 is self-balanced under the action of the plurality of lower cables 3; the middle rod 4 is slidably arranged in the sleeve 2, and the plurality of upper cables 5 are circumferentially distributed on the outer wall of the middle rod 4, and one end of each upper cable 5 is connected to the connection node 11, and the other end is connected to the outer wall of the upper end of the middle rod 4; the middle part of the flexible membrane 6 is connected to the upper end of the middle rod 4, and the edge of the flexible membrane 6 is connected to the membrane support frame 1, and covered and supported on the plurality of upper cables 5. When the umbrella-shaped supported cable-membrane structure is in use, the center rod 4 moves up along the axial direction of the sleeve 2 to put the upper cable 5 and the flexible membrane 6 in a taut state; when the umbrella-shaped supported cable-membrane structure needs maintenance and repair, the center rod 4 moves down along the axial direction of the sleeve 2 to put the upper cable 5 and the flexible membrane 6 in a relaxed state, so as to facilitate the replacement of the flexible membrane 6 or the upper cable 5.

[0046] In the umbrella-shaped supported cable-membrane structure, the sleeve 2 is suspended by a plurality of lower cables 3, and the sleeve 2 achieves self-balancing under the action of gravity, so that when the center rod 4 slides in the sleeve 2, locking can be avoided. After long-term use, the overall structure may be deformed, but the sliding of the center rod 4 in the sleeve 2 can be unaffected by adjusting the lower cables 3, and the adjustment is convenient. In addition, the sliding of the center rod 4 in the sleeve 2 can realize the relaxation of the flexible membrane 6 and the upper cable 5, which can facilitate the renovation and repair, and the operation is convenient. When in use, no other cumbersome operations are required. The flexible membrane 6 and the upper cable 5 can be tightened by moving the center rod 4 upward, and the tightening force can be effectively controlled.

[0047] Optionally, the center rod 4 can be driven by a driving mechanism when moving in the sleeve 2, so as to facilitate the upward movement of the center rod 4 to push the flexible membrane 6 to make it tight; when the center rod 4 moves downward in the sleeve 2, the center rod 4 can move downward by its own weight.

[0048] Optionally, the driving mechanism may be a hand chain hoist, the fixed end of which is mounted on the sleeve 2, and the movable end is connected to the center rod 4, so that the center rod 4 can be moved upward relative to the sleeve 2 by pulling the hand chain hoist.

[0049] In order to keep the flexible membrane 6 and the upper cable 5 in a taut or relaxed state, Figure 3As shown, the umbrella-shaped supported cable-membrane structure further includes a fixing assembly 7, which is connected between the sleeve 2 and the center rod 4 to limit the center rod 4 and the sleeve 2, so as to limit the center rod 4 from sliding in the sleeve 2. That is, after the center rod 4 moves up to a set position or moves down to a set position, the fixing assembly 7 locks the center rod 4 and the sleeve 2.

[0050] The cam 72 is provided with a plurality of nuts 72 disposed on each of the screw rods 71 ​​, and the first end plate 21 is provided at least at one end of the two ends of the sleeve 2 along its axial direction. In the present embodiment, the first end plate 21 is provided at both ends of the sleeve 2, and the second end plate 41 is provided at the lower end of the middle rod 4. The plurality of screws 71 are distributed circumferentially around the axis of the sleeve 2 and pass through the two first end plates 21 and the second end plates 41, and at least two nuts 72 on each screw 71 are screwed on the first end plate 21, that is, one nut 72 is located on the upper end surface of one first end plate 21, and the other nut 72 is located on the lower end surface of the other first end plate 21, so as to limit the screw 71 and the sleeve 2, and at least two nuts 72 on each screw 71 are screwed on the second end plate 41, that is, one nut 72 is located on the upper end surface of the second end plate 41, and the other nut 72 is located on the lower end surface of the second end plate 41, so as to limit the screw 71 and the middle rod 4. This structure realizes that the fixing assembly 7 connects the sleeve 2 and the center rod 4 so that the center rod 4 and the sleeve 2 do not move relative to each other. When the position of the center rod 4 needs to be adjusted, the nut 72 can be loosened and made to move to ensure the movement of the center rod 4.

[0051] Furthermore, in order to increase the connection strength of the screw rod 71, the fixing assembly 7 further includes a reinforcing plate 73, which is disposed at the lower end of the screw rod 71 and is fixedly connected to the plurality of screw rods 71 ​​to enhance the connection strength. The screw rod 71 and the reinforcing plate 73 may be fixedly connected by two nuts 72 or by welding.

[0052] Alternatively, if Figure 4 As shown, the connection section 11 includes a vertical tube 111 and a first connection plate 112 disposed on the outer wall of the vertical tube 111. The vertical tube 111 is disposed on the main structure 100. The first connection plate 112 is provided with a first hinge hole 1121 and a second hinge hole 1122 distributed up and down. One end of the upper cable 5 is connected to the first hinge hole 1121, and one end of the lower cable 3 is connected to the second hinge hole 1122. This structure makes it more convenient to connect the upper cable 5 and the lower cable 3 to the connection section 11.

[0053] Furthermore, in order to facilitate the connection between the vertical pipe 111 and the main structure 100, a first flange 1111 is provided at the lower end of the vertical pipe 111, and a second flange 101 is provided at the upper end of the main structure 100. The first flange 1111 and the second flange 101 are connected by a first fastener to fix the connecting section 11 to the main structure 100.

[0054] Optionally, the first fastener may be a clamp or a plurality of bolts.

[0055] Optionally, refer to Figure 3 The outer wall of the sleeve 2 is provided with a plurality of second connecting plates 22 corresponding to the lower pull cables 3 one by one, and the second connecting plates 22 are provided with third hinge holes 221, and the other end of the lower pull cable 3 is connected to the third hinge hole 221. This structure makes the connection between the lower pull cable 3 and the sleeve 2 more convenient.

[0056] Alternatively, if Figure 5 As shown, the outer wall of the upper end of the middle rod 4 is provided with a plurality of third connecting plates 42 corresponding to the upper cables 5 one by one, and the third connecting plates 42 are provided with fourth hinge holes 421, and the other end of the upper cables 5 is connected to the fourth hinge holes 421. This mechanism makes it more convenient to connect the upper cables 5 to the middle rod 4.

[0057] In this embodiment, both ends of the upper cable 5 and both ends of the lower cable 3 are provided with locks, and the locks are hinged to the corresponding first hinge hole 1121, second hinge hole 1122, third hinge hole 221 or fourth hinge hole 421 through a pin shaft.

[0058] In this embodiment, both the upper cable 5 and the lower cable 3 can be selected to be flexible steel cables.

[0059] In order to further improve the stability of the flexible membrane 6 , the umbrella-shaped supported cable membrane structure also includes a top cover 8 , which is connected to the upper end of the center rod 4 , and the flexible membrane 6 is clamped between the center rod 4 and the top cover 8 to clamp the flexible membrane 6 .

[0060] Specifically, the top cover 8 and the center rod 4 are connected by a second fastener 81, and the second fastener 81 passes through the top cover 8 and the flexible membrane 6 in sequence and is connected to the upper end of the center rod 4, so that the top cover 8 and the center rod 4 clamp the flexible membrane 6 to improve the stability of the flexible membrane 6.

[0061] Optionally, the second fastener 81 may be a plurality of screws.

[0062] Alternatively, if Figure 2As shown, four lower cables 3 and connecting joints 11 are arranged one by one, and the four connecting joints 11 are arranged diagonally in pairs. One end of the four lower cables 3 is connected to the four connecting joints 11 respectively, and the other end is connected to the sleeve 2. In this structure, the four lower cables 3 simultaneously apply tension to the sleeve 2, so that the sleeve 2 is better balanced; and when the lower cables 3 cannot meet the use requirements after long-term use, the lower cables 3 can be replaced one by one, that is, when one lower cable 3 is removed, the remaining three lower cables 3 can still apply tension to the sleeve 2 to keep the sleeve 2 suspended, so that the lower cables 3 are easy to replace, and the overall structure is not affected.

[0063] Refer to Figure 1 In order to facilitate the operation and construction, the umbrella-shaped supported cable membrane structure further includes a cable platform 9, which can be connected to the lower cable 3 through a pulley. The cable platform 9 and the pulley can be connected by ropes, and at least three ropes can be selected to ensure the stability of the cable platform 9. The pulley slides on the lower cable 3 to move the cable platform 9 from the main structure 100 to the position of the sleeve 2, so that the construction personnel can operate on the cable platform 9 conveniently.

[0064] Optionally, the umbrella-shaped supported cable membrane structure further includes a hanger 10 , which can be installed on the outer wall of the sleeve 2 via a rope so that the hanger 10 is located directly below the sleeve 2 , so as to facilitate construction workers to perform construction operations through the hanger 10 .

[0065] In this embodiment, if the umbrella-shaped supported cable membrane structure needs to be renovated and repaired, the characteristic of the lower cable 3 that gravity is always in self-balance can be fully utilized, and a cable platform 9 can be set on the lower cable 3, or a hanger 10 can be set under the sleeve 2 to inspect and maintain the umbrella-shaped supported cable membrane structure, or replace the flexible membrane 6. In practice, the flexible membrane 6 is divided into multiple membranes. The operation is as follows: the flexible membrane 6 is replaced in the position of the original flexible membrane 6 by first dismantling and then replacing. During the construction process, the construction sequence of unit membranes is adopted, and the membranes on the edge are used as the construction platform. After each membrane is removed, a new membrane is replaced in situ; the above-mentioned membrane can be measured according to the actual site, and the membrane processing is carried out after the geometric dimensions of each membrane are determined. Moreover, during the above construction process, by releasing the middle rod 4, the geometrical position of the lower cable 3 remains almost unchanged, and the upper cable 5 and the flexible membrane 6 are passively tightened or relaxed as the middle rod 4 moves upward or downward, without the need to actively tension the upper cable 5 or the flexible membrane 6. The cable force of the upper cable 5 and the membrane surface stress of the flexible membrane 6 can be effectively controlled only by moving the middle rod 4 upward or downward.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
