Embodiment

[0020] This application is mainly for figure 2 In this existing commonly used cable bridge installation implementation structure, a new type of cable bridge expansion and settlement joint connection device is implemented, such as Figure 3-4 As shown, it includes two sets of connecting mechanisms. The connecting mechanism includes a joint 1 and a U-shaped steel frame 13 welded and fixed to each other. The joint adopts a U-shaped cover plate size that matches the bridge frame, which is easy to install. A pair of steel handles is welded on the joint 1. 11. It is convenient for construction personnel to carry, and four bolt holes 3 are drilled on both sides of the joint 1 for fixing with bridge bolts. The U-shaped steel frame 13 is formed by welding three trapezoidal steel plates, and the thickness is between 5-10 mm. For different bridge specifications, commonly used bridge specifications are 200×100, 100×50, and the joint size can be adjusted accordingly. The nylon cloth at t...

Abstract

The invention discloses a novel connection device for a telescopic and settlement seam of a cable bridge frame. The device includes two sets of connection mechanisms, a U-shaped telescopic mechanism is disposed between the connection mechanisms, two ends of the U-shaped telescopic mechanism are respectively connected with the corresponding connection mechanisms, a supporting mechanism is disposedinside the U-shaped telescopic mechanism, and the supporting mechanism is connected with the inside of the U-shaped telescopic mechanism. In a present bridge frame system, through a treatment manner of structure telescopic settlement seams, the bridge frame mainly utilizes a reserved butt joint seam, an expansion joint is easy to make the cable bridge frame ventilate and make dust enter, and the cable life is affected.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a novel cable bridge telescopic settlement joint connection device. Background technique [0002] Due to its compact and reasonable structure, strong bearing capacity, and convenient installation, the cable tray is widely used in electrical power engineering, computer network engineering, fire engineering and other fields. The cable tray makes the laying of cable lines and the network wiring of high-rise buildings neat, beautiful and standardized. Cable trays are generally composed of trays and ladder frames (straight sections, bends, accessories, and hangers) to support cables. However, as a steel structure, the bridge frame must undergo corresponding anti-displacement treatment when passing through the structural expansion and settlement joints. In the current bridge system, the way the bridge passes through structural expansion and settlement joints is mainly to use b...
