Abstract
The utility model discloses a ballasted railway bridge expansion device, which is mainly formed by that an upper plate and a water sealing strip are connected. The utility model is characterized in that a sliding plate is arranged between one side of the water sealing strip and the upper plate, the structure is reasonable, the utility model can effectively prevent ballast of a railway from leaking in expansion joint of beam ends, the beam bodies of the both ends of the joint are connected into a whole by the water sealing strip, and a rubber water sealing strip is pressurized and sealed to achieve the water sealing purpose by the self weight of the ballast; meanwhile, as the upper plate is fixed with one end of the water sealing strip, the other end is slid with the sliding plate stuck on the water sealing strip, and expansion effect can be achieved. In addition, as the beam body is provided with embedded channel steel, the convex fold of the bottom of the water sealing strip is directly slipped into the channel steel; when the utility model is installed, welding is not needed, bolt fixation is not needed either, the construction cost is reduced, and the operating safety is high.
Description
Technical field:
The utility model relates to a kind of bridge extension joint, particularly relate to a kind of with have the quarrel railroad bridge be connected stretching device.
Background technology:
In existing technology, there is the quarrel railroad bridge not establish stretching device, fill in the beam-ends slit for preventing ballast aggregate, only cover the iron plate quarrel that is in the way.But along with the rise of high-speed railway, the protection of beam-ends prestressing force anchor head and pot bearing makes the shrinkage joint sealing of quarrel railroad bridge, the problem that antirust problem becomes engineers and technicians.Therefore, be badly in need of a kind of quarrel that can be in the way of exploitation, again can sealing and stretch, and novel telescopic device easy for installation could satisfy its instructions for use.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, the quarrel that can be in the way and can the flexible bridge extension joint of sealing.The technical scheme that its technical problem that solves the utility model adopts is, a kind of have a quarrel railroad bridge stretching device, mainly is to be connected to form by upper plate and sealing rod, and its characteristics are: be provided with sliding panel between a side of sealing rod and upper plate.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is rational in infrastructure, be skillfully constructed, can stop effectively that the railway ballast aggregate bleeds in the beam-ends clearance of expansion rail, to stitch two end carriage bodies by sealing rod and fuse, pressurization reaches the sealing purpose to the rubber sealing rod to utilize the ballast aggregate deadweight.Simultaneously, because upper plate and sealing rod one end are fixed, the other end slides with the sliding panel that sticks on the sealing rod, reaches telescopic action.In addition, because the beam body is provided with pre-buried channel-section steel, sealing rod bottom flange is directly filled in the channel-section steel, so installation is very convenient, and site operation, neither welding also without bolt, reduces construction cost greatly, and safe and reliable, the tool promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Among the figure, a kind of have a quarrel railroad bridge stretching device, mainly be to be connected to form by upper plate 10 and sealing rod 30, a side of upper plate 10 is provided with a boss block 11, and upper plate 10 adopts the 45# steel plate zinc-plated through processing, sealing rod 30 is made by rubber, its both sides are respectively equipped with flange 31,32, and wherein, flange 32 is provided with a groove 31, groove 31 is chimeric with boss block 11, and 10 of a side of sealing rod 30 and upper plates are provided with sliding panel 20.The effect of sliding panel 20 is, the friction factor between upper plate 10 and the sealing rod 30 reduced, thereby can relatively move between the two, satisfies to use, and flexible surplus arranged when the beam body heat expands shrinkage.
