The invention discloses a monitoring cable connection device for a medical anesthesia plane monitor, which includes a mounting block, a connecting seat, a connecting rod connecting the former two, and a clamping column. A base is installed on the seat, and the hoop plate is provided with an inlet hole for the cable to enter. Both the hoop plate and the side wall of the base are provided with a connecting block and a connecting plate. Through the cooperation of the connecting block and the connecting plate , so that multiple sets of connecting devices can be assembled and installed, a clamping hole flush with the center of the cable inlet hole is provided on the connecting seat, and the clamping column is arranged in the clamping hole to clamp the cable joint. The beneficial effect of the present invention is that the clamping mode of the device is smoother and the operability is higher by means of gear driving, and the cable can be fixed at the same time as the cable is connected, avoiding a series of external fixing processes The hidden danger of cable loosening and reduce the difficulty of installation.

The invention discloses a super-large span peripheral simply-supported prestressed double-layer and three-layer combined torsional reticulated shell structure, which comprises a torsional reticulated shell (1); framework columns (2) with unequal heights are arranged on the periphery of the torsional reticulated shell (1) according to the column reticulated distance requirement, and a central framework column (3) is arranged in the center of each side of the torsional reticulated shell (1); the overhung parts of the torsional reticulated shell (1) are simply supported at the tops of the framework columns (2); and a prestressed steel cable (4) is arranged on the central framework column (3) in the center of each side of the torsional reticulated shell (1). The combined torsional reticulated shell structure has good structural integrity, the lateral rigidity resistance of the structure is greatly improved, the hidden danger caused by the super-large overhung parts is eliminated, the steel for the structure is further optimized, the consumption of the steel is greatly reduced, and the requirements of 'energy conservation and synergism' are met; and the structure is particularly suitable for a super-large span torsional reticulated shell roof with span of 120 to 180 meters, and is a safe, reasonable, advanced and economic novel structural system.
