Abstract
The utility model discloses a road bridge expansion joint and belongs to the technical field of expansion joints. According to the technical scheme, the road bridge expansion joint comprises a first profile steel body, a second profile steel body and a water stop mechanism, and is characterized in that the water stop mechanism is arranged between the first profile steel body and the second profile steel body. The water stop mechanism comprises a sealing strip and inserted blocks, the inserted blocks are connected to the two ends of the sealing strip respectively, inserted grooves are formed in the first profile steel body and the second profile steel body, and the inserted blocks are arranged in the corresponding inserted grooves. Compared with the prior art, the road bridge expansion joint has the advantages of being convenient to install, low in cost, little in noise and vibration, standard, easy to replace, and capable of enabling seams of road surfaces or bridge floors to be firmer and effectively prolonging the service life of a road or bridge.
Description
Technical field
The utility model relates to the stretching device technical field, relates in particular to a kind of Expansion Units for Highway Bridges.
Background technology
At the highway pavement made from concrete or bridge floor, thereby leave the slit in order to prevent because expand with heat and contract with cold to cause between highway pavement or every section 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 of seam: 1, the rubber extensible member in the stretching device is to be connected with seam by secure component, and secure component adopts metal to make usually.2, be connected with seam by bonding agent, and the common employing of bonding agent is epoxy resin.But Telescopic rubber device since rubber peel usually with the generation CONTACT WITH FRICTION such as vehicle, thereby often be in tension state, so fragile and aging, and easily come off.Therefore above-mentioned two types all can not fundamentally solve the fastness problem that highway pavement or bridge floor seam connect.
The utility model content
The purpose of this utility model is the deficiency that exists for prior art, a kind of Expansion Units for Highway Bridges is provided, this utility model has easy for installation, with low cost, noise and vibrate little, the easily changeable characteristics of standardization can make the seam of highway pavement or bridge floor more firm, effectively prolong the application life of highway or bridge.
The purpose of this utility model is achieved through the following technical solutions: a kind of Expansion Units for Highway Bridges, comprise the first shaped steel, the second shaped steel and Water stop mechanism, be provided with Water stop mechanism between described the first shaped steel and the second shaped steel, described Water stop mechanism comprises weather strip and abaculus, described weather strip two ends are connected with respectively abaculus, be provided with caulking groove on described the first shaped steel and the second shaped steel, described abaculus is arranged on corresponding caulking groove the inside.
Be provided with anti-slipping mechanism on described the first shaped steel and the second shaped steel.
Described the first shaped steel and the second shaped steel are " C " shaped steel.
Described the first shaped steel and the second shaped steel are " E " shaped steel.
Described the first shaped steel and the second shaped steel are " F " shaped steel.
The beneficial effects of the utility model are: the utlity model has easy for installation, with low cost, noise and vibrate littlely, the easily changeable characteristics of standardization can make the seam of highway pavement or bridge floor more firm, effectively prolong the application life of highway or bridge.
