Abstract
The utility model discloses a concealed highway bridge expansion device. The concealed highway bridge expansion device comprises a first piece of shape steel, a second piece of shape steel, a rubber strip base and a water stopping mechanism. The concealed highway bridge expansion device is characterized in that the first piece of shape steel and the second piece of shape steel are respectively of an E-shaped structure, and are arranged at the left end and the right end of the rubber strip base in a vulcanization mode respectively, the water stopping mechanism is arranged between the first piece of shape steel and the second piece of shape steel, and comprises an expansion joint body, the middle of the cross section of the expansion joint body is of a W-shaped structure, the left side and the right side of the W-shaped structure respectively extend to form a side wing, first grooves are formed in the obverse sides of the two side wings, a plurality of protruding ribs are arranged on the reverse sides of the two side wings, a second groove is formed between every two adjacent protruding ribs, protrusions which are used in cooperation with the second grooves are arranged on the first piece of shape steel and the second piece of shape steel, fixing blocks are arranged at the bottom of the first piece of shape steel and the bottom of the second piece of shape steel respectively, and a spring is arranged between the fixing blocks. The concealed highway bridge expansion device is simple in structure and reasonable in design, and the degree of expansion deformation of the expansion joint is improved.
Description
Technical field
The utility model relates to stretching device technical field, relates in particular to a kind of built-in Expansion Units for Highway Bridges.
Background technology
At the highway pavement made from concrete or bridge floor, thereby leave gap in order to prevent because expand with heat and contract with cold to cause between highway pavement or every section of member of bridge floor, therefore in existing work progress, often adopt Telescopic rubber device to overcome, its structure can be divided into two types by it with the connected mode at shrinkage joint: 1, the rubber extensible member in stretching device is to be connected with shrinkage joint by secure component, and secure component adopts metal to make conventionally.2, be connected with shrinkage joint by bonding agent, and the common employing of bonding agent is epoxy resin.But Telescopic rubber device due to rubber peel conventionally with the generation CONTACT WITH FRICTION such as vehicle, thereby often in tension state, therefore fragile and aging, and easily come off; Adopt cementing agent to be connected with shrinkage joint, this shrinkage joint dilatation amount is little, and elasticity is poor.Therefore above-mentioned two types all can not fundamentally solve highway pavement or bridge floor shrinkage joint connectivity problem.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, and the built-in Expansion Units for Highway Bridges that a kind of dilatation amount is large is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of built-in Expansion Units for Highway Bridges, comprise the first shaped steel, the second shaped steel, rubber strip pedestal and Water stop mechanism, described the first shaped steel and the second shaped steel are " E " shape structure, the first shaped steel and the second shaped steel vulcanize respectively the left side at rubber strip pedestal, right two ends, the centre of the first shaped steel and the second shaped steel is provided with Water stop mechanism, described Water stop mechanism comprises shrinkage joint body, the centre of shrinkage joint body cross-section is " W " shape structure, and on the left side of " W " shape structure, right both sides are extended with two flanks, be equipped with groove I in the front of two flanks, be equipped with many convex tendons at the back side of two flanks, between adjacent convex tendon, be provided with groove II, on described the first shaped steel and the second shaped steel, be provided with the projection matching with described groove II, the bottom of the first shaped steel and the second shaped steel is equipped with fixed block, between fixed block, be provided with spring.
The beneficial effects of the utility model are: 1, the utility model the first shaped steel and the second shaped steel vulcanize respectively the left and right two ends at rubber strip pedestal, therefore there is excellent physical and mechanical properties, splendid Weather-resistant, good sealing effectiveness, product simple installation is quick; 2, the utility model is by Highway Bridge Expansion Joint being made to " W " shape structure, and extends and be provided with two flanks in the both sides of described " W " shape structure, therefore improved the dilatation amount at shrinkage joint.
