Problems solved by technology
The main features of the existing structure are: the special section steel is used as the supporting body, although the strength is high, but the cost is also high, and it is too wasteful to use it in rail transit; the waterproof rubber strip is embedded in the section steel notch, and the waterproof effect is good, but it is troublesome to install and disassemble. The slag-retaining steel plate 14 and the track laid on the upper part must be removed when used in rail transit, which is not only a large amount of work but also difficult; when making beams according to the existing technology, it is necessary to reserve notches, and then re-cast the beams after hanging them Installation not only increases the construction cost, but more importantly, it is difficult to ensure the accuracy of casting construction

Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the structure of a kind of rail transit bridge expansion device provided by the present invention is described in further detail:
[0019] Such as figure 2 Shown is the structural representation of the rail transit bridge telescoping device provided by the invention, and its structure includes: symmetrically poured in beam body or bridge abutment prefabricated part 26 and is provided with the profile steel 23 that the structure of anchor screw 25 is angle steel; Wherein, beam body or The abutment prefabricated part 26 is a cutaway structure, and a pouring formwork 22 is provided at the cutaway; one end 28 of the section steel 23 protrudes from the notch of the beam body or the abutment prefabricated part, and the two sides are grooves 29 The "U" shaped waterproof rubber strip 24 snaps into the protruding end 28 of the profile steel; the bottom surface corresponding to the waterproof rubber strip is provided with a slag-re...

The invention belongs to the technical field of telescopic devices of bridges, and in particular discloses a telescopic device of a rail transit bridge. According to the main technical scheme, the telescopic device comprises a slag blocking steel plate, profile steel and a fixed waterproof rubber strip, wherein the profile steel has an angle steel structure and is symmetrically cast in a beam body or bridge abutment prefabricated piece, the beam body or bridge abutment prefabricated piece has an unfilled corner structure, one end of each piece of profile steel protrudes an unfilled corner of the beam body or bridge abutment prefabricated piece, and two sides of the waterproof rubber strip are respectively clamped with the protruding ends of the profile steel. The telescopic device of the rail transit bridge has the advantages of good dustproof and waterproof effect, simplicity in construction and installation and convenience in replacement.
Description
Technical field [0001] The present invention belongs to the technology field of bridge telescopic device, and it is specifically disclosed that a type of rail transit bridge telescopic device has been disclosed. Background technique [0002] The existing rail transit bridge telescopic device is basically a simple transformation of the road bridge telescopic device, and it has not improved substantial improvement. This makes the existing rail bridge telescopic device is not completely suitable for the needs of the bridge.Highway bridge bridges directly pass the car, and the rail transit bridge passes through the rail trains, so the purpose and significance of the two types of bridges to set up the telescopic device are not exactly the same.It is the first. The telescopic device of the rail transit bridge does not directly contact the train wheel. The main purpose is to prevent waterproof and dustproof, and replace it with simple and convenient. [0003] figure 1 It is shown in th...
