Embodiment Construction

[0049] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0050] Such as figure 1 , figure 2 , image 3 and Figure 4As shown, the connecting device of the prefabricated floating slab in this embodiment includes the floating slabs 1 which are butted and installed to form a long track bed. The middle of the track bed formed by two adjacent floating slabs 1 is a square hole 7. The side waist is an opening 8; the two sides of the floating plate 1 are provided with grooves, and a channel steel 5 is installed in the groove, and a round hole 6 is opened on the channel steel 5, and a connecting piece 3 is installed inside the channel steel 5, and through the long Bolt 4 is locked.

[0051] Such as Figure 5 As shown, the structure of a single floating slab 1 is as follows: it includes a slab body, and one end of the slab body extends two concrete arms with a rectangular cross-section, so that two ...

Abstract

The invention relates to a connection device for prefabricated floating slabs and a construction method thereof. The connection device comprises the floating slabs which are in butt joint with each other, the floating slabs are connected into a long strip track bed, a square hole is formed in the middle of the track bed formed by the two adjacent floating slabs, and openings are formed in the waist portions on two sides; grooves are formed in two side surfaces of each floating slab, channel steel is mounted in the grooves, circular holes are formed in the channel steel, and connection parts are mounted in the channel steel and are locked through long bolts. The connection device is compact and reasonable in structure and convenient to operate and adopts a side mighty shearing hinge, the shearing hinge is high in shearing force transmitting capacity and good in rail smoothness and vibration isolation effect, meanwhile the installation space problem of the adjacent floating slabs is solved, posture errors are reduced, and the positioning problem is solved.

Description

technical field [0001] The invention relates to the technical field of connecting devices, in particular to a connecting device for a prefabricated floating slab and a construction method thereof. Background technique [0002] With the rapid development of urban rail transit, the response of the rail system caused by the continuous increase of vehicle speed is gradually increasing. The simple use of fasteners or ballast bed vibration isolation pads for vibration isolation can no longer meet some special vibration reduction requirements. Floating slab track bed technology is one of the most effective rail vibration and noise reduction technologies, especially in subways and urban light rails. This technology has been widely used, and it is suitable for vibration reduction requirements of 16dB-25dB road section. [0003] However, for the convenience of installation, the prefabricated floating slab usually has a relatively small longitudinal length. If the mass of a single pl...
