Abstract
The utility model belongs to the technical field of a telescopic device, and discloses a special-shaped steel rubber telescopic device used between railways and subway beam bodies. The special-shaped steel rubber telescopic device is characterized by comprising a pair of left and right special-shaped steel, wherein sections of the special-shaped steel are in H-shaped structures. A water-stopping mechanism formed by a rubber water-stopping band or/and a middle beam is arranged between the left special-shaped steel and the right special-shaped steel. Grooves are arranged on outer side faces or outer lower side faces of the special-shaped steel in the H-shaped structures. Water-stopping strips which expand when meeting water are embedded in the grooves. The telescopic device can effectively reduce impact of car tires to a connection face, prevents pavement water from leaking to the middle of a pavement along a connection portion, and can effectively prolong service life of a bridge pavement.
Description
Technical field
The utility model belongs to the stretching device technical field, relates in particular to a kind of for the deformed steel Telescopic rubber device between railway, the subway beam body.
Background technology
Railway, urban rail transit construction fast development need to install stretching device on the bridge.The structure of present employed stretching device is by consisting of for the deformed steel girder body that is fixed on bridge seam both sides and the rubber water-proof weather strip that is fixed in therebetween.This deformed steel Telescopic rubber device is because the lateral surface top of the deformed steel of its formation is straight flange (or right angle) structure, so that easily infiltration of the cement junction (face) at this straight flange place, structure and the intensity of road surface, junction (cement or concrete) have been reduced, so that the as easy as rolling off a log damage in the road surface of stretching device and pontic.
The utility model content
The purpose of this utility model is exactly that a kind of deformed steel Telescopic rubber device that can effectively protect stretching device and road surface, pontic junction will be provided.
For achieving the above object, the technical scheme that adopts of the utility model is:
A kind of deformed steel Telescopic rubber device comprises the deformed steel of paired setting and is arranged at therebetween the Water stop mechanism with water stopping function that the cross section of at least one deformed steel is " worker " type structure in the deformed steel of described paired setting.
The additional technical feature that consists of the deformed steel Telescopic rubber device also comprises:
---described " worker " type structure deformed steel outside or outer downside are provided with groove, and are embedded with the water-swellable sealing rod in this groove;
---the end face at described " worker " type structure deformed steel is provided with anti-slipping mechanism.
A kind of deformed steel Telescopic rubber device provided by the utility model, compared with prior art have the following advantages: one, since consist of this deformed steel Telescopic rubber device at least one deformed steel the cross section be " worker " type structure, can so that bridge pavement embed wherein, consist of with it overall structure, can effectively reduce vehicle tyre to the impact of bonding surface, be conducive to the application life on road surface; Its two, " worker " type structure deformed steel outside or outside downside be provided with groove, and in this groove, be embedded with the water-swellable sealing rod, can effectively stop road surface water along the junction to the road surface in seepage, can effectively prolong application life of bridge pavement; Its three, at the end face of " worker " type structure deformed steel anti-slipping mechanism is set, can be conducive to the driving safety of vehicle for the deformed steel end face of widening.
Description of drawings
The structural representation of the deformed steel Telescopic rubber device that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation of the second deformed steel Telescopic rubber device.
The specific embodiment
Be described further below in conjunction with the structure of accompanying drawing to a kind of deformed steel Telescopic rubber device provided by the utility model.
As shown in Figure 1, for consisting of the structural representation of deformed steel Telescopic rubber device provided by the utility model, the structure that consists of this glue stretching device comprises that left and right (a pair of) two cross sections are the deformed steel 1 and 2 of " worker " type structure, and this left and right deformed steel 1 and 2 are provided with and comprise rubber fastening band 3 or/and the Water stop mechanism that central sill 4 consists of; Downside 9(or deformed steel lateral surface 10 as shown in Figure 2 outside " worker " type structure deformed steel) be provided with groove 5, and in this groove, be embedded with water-swellable sealing rod 6.
In above-mentioned deformed steel Telescopic rubber device structure
---in order to improve the safety of Vehicle Driving Cycle, be provided with at the end face 7 of described " worker " type structure deformed steel comprise slot stick 8(or raised line) anti-slipping mechanism;
---consist of two deformed steels of stretching device, both can be two and be set to simultaneously " worker " type structure; Also can be that one of them is set to " worker " type structure, consist of stretching device applicable to only needing on the one-way traffic bridge by the deformed steel of this structure and the deformed steel of other structure.
