Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a connecting device between dynamic and static structures in a cable-membrane project. Background Art

[0002] For enclosed projects in coastal and humid environments, it is most reasonable to use cable membrane structure as the enclosure structure, which is corrosion-resistant and has a long service life.

[0003] Large-scale cable-membrane projects often require overall closure. Under the action of various working loads, especially wind loads, the cable-membrane structure is always in an irregular swinging state. When the whole is required to be completely closed, the dynamic structure needs to be connected to the static structure (such as the ventilator at the bottom) and the membrane structure installed. If the external force generated by the dynamic structure is not effectively handled, it will be transmitted to the static structure and cause deformation and even damage to the static structure.

[0004] In the current cable-membrane structure enclosure project, there are difficulties in the connection between the edge-sealing cable and the lower ventilation louver. The edge-sealing cable and the membrane structure are in an irregular swinging state under various loads, especially wind loads, while the lower ventilation louvers are in a static state. If full closure is to be achieved, a connecting device must be arranged between the two to achieve the installation of the membrane. The device should avoid transmitting the force generated by the dynamic structure to the static structure, otherwise it will damage the static structure. The current practice is that the edge-sealing cable and the louver are open, which cannot meet the requirements of full closure. Second, in order to achieve full closure, the edge-sealing cable is cancelled and replaced with a large steel truss, which increases the amount of steel structure and the bearing capacity of the foundation, greatly increasing the project cost.

[0005] In summary, the connection method between the edge banding cable and the lower ventilation louver in the existing cable-membrane engineering cannot effectively handle the external force generated by the dynamic structure, resulting in the deformation and even damage of the static structure after the force is transmitted to the static structure. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that the connection method between the edge sealing cable and the lower ventilation louver in the existing cable-membrane engineering cannot effectively deal with the external force generated by the dynamic structure, resulting in deformation and even damage of the static structure after the force is transmitted to the static structure, and thus provide a connection device between the dynamic and static structures in the cable-membrane engineering.

Other components and connection relationships are the same as those of the specific embodiments one, two, three, four, five or six.

[0043] Specific implementation method eight: Combination Figures 1 to 6 To illustrate this embodiment, the center lines of the two adjacent groups of guide mechanism mounting holes in this embodiment are arranged vertically. This arrangement can ensure that the inner and outer sleeves are arranged coaxially. The other components and connection relationships are the same as those of the specific embodiments one, two, three, four, five, six or seven.

[0044] Specific implementation method nine: Combination Figures 1 to 6The present embodiment is described. The guide mechanism 3 of the present embodiment includes a guide cylinder 301, a guide ball 302, a pressure spring 303, an adjusting bolt and a locking nut 304.

After the installation is completed, in the natural state, the distance between the lower edge of the outer sleeve 202 of the telescopic mechanism 2 and the upper plate 105 of the tilting mechanism 1 is 50 mm, which is the contraction amount of the telescopic mechanism 2 in the length direction.
