[0002] The bidirectional cable-stayed lattice shell is a structural form with the advantages of light weight, strong rigidity, economy and practicality. It is widely used in public buildings such as gymnasiums, exhibition centers, subway stations and indoor sports venues. The bidirectional cable-supported support node is the focus of the design of the bidirectional cable-stayed lattice shell structure and an important factor affecting the safety of the bidirectional cable-stayed lattice shell structure. How to make the node structure meet the structural force requirements and reflect good economy, have a simple and clear force transmission path and meet the increasingly high standards of modern architecture are the main problems that must be solved in the node design. Traditional bidirectional cable-supported support connections generally use cast steel nodes, which have a long manufacturing cycle, high cost, and difficult construction. Utility Model Content

[0006] Furthermore, the support rod is a hollow circular tube, and the support rod sealing plate is a circular plate with a diameter not less than the outer diameter of the support rod.

[0007] Furthermore, the clamping plates on the upper and lower sides of the cable groove of the longitudinal cable clamp are respectively provided with a plurality of pairs of bolt holes, and the longitudinal cable passing through the cable groove is clamped by high-strength bolts.

[0008] Furthermore, the axial directions of the pin holes on the left ear plate and the right ear plate are parallel to the longitudinal cables.

[0009] Furthermore, the left ear plate and the right ear plate are symmetrical to each other, and the left ear plate, the right ear plate and the longitudinal cable clamp form a cross shape, and the center of the cross is located on the central axis of the support rod.

[0010] Furthermore, the left transverse locking clamp and the right transverse locking clamp are both composed of an ear plate end and a columnar end which are connected to each other as one body, the ear plate end is composed of two ear plates which are parallel to each other, and the columnar end has a through hole in the central axis.

[0011] Furthermore, the left ear plate is connected to the left transverse locking clip ear plate end through a pin shaft, and the left transverse locking clip columnar end is fixedly connected to the left transverse rope end head; the right ear plate is connected to the right transverse locking clip ear plate end through a pin shaft, and the right transverse locking clip columnar end is fixedly connected to the right transverse rope end head.

[0012] The utility model also provides a bidirectional tensioned lattice shell structure adopting the bidirectional cable-bearing support connection nodes.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The bidirectional cable-bearing support connection node provided by the utility model has a transverse cable disconnected at the node, and is connected to the ear plate through a pin shaft to transmit force, while the longitudinal cable is connected at the node, which avoids the difficulty of node production and construction caused by continuous pulling of both cables at the node; and because the transverse cable is disconnected, it is possible to tension the cable in sections, and the difficulty of cable construction tensioning is also reduced. The bidirectional cable-bearing support connection node structure of the utility model fits the force characteristics of the bidirectional cable-bearing support structure, and the force transmission is direct, safe and reliable. It is convenient to use for the bidirectional tensioned lattice shell structure, and the quality is controllable. It can effectively reduce the difficulty of node production and the difficulty of cable structure construction tensioning, and realize the economy and convenience of building construction.
