Abstract
The utility model discloses an assembly type bridge plate which is used in highway steel bridges. The assembly type bridge plate is characterized by comprising an underframe, wherein the underframe is fixedly connected with a panel, the underframe comprises at least two 'I'-shaped ribs which are longitudinally arranged, channel steel which is longitudinally arranged and at least two small crossbeams which are longitudinally arranged. Under the condition that an original steel bridge system and a crossbeam structure keep unchanged, an old steel bridge crossbeam is fully used and reconstructed to form a new assembly type bridge plate which is used in the highway steel bridges, which not only can fully use the old steel bridge crossbeam, which achieves that waste is fully used and reconstructed, but also has a more fixedly structure after reconstruction.
Description
[technical field]
The utility model relates to the assembly type steel bridge on highway bridge plate.
[background technology]
Existing Steel plate bridge, it comprises underframe (the said old longeron of people just), underframe is connected between worker's type rib tie-beam by three worker's type ribs of vertical setting and some to be formed, the fixing panel of being made by the wooden bridge plate of lid again on underframe.The supporting wooden bridge plate of this steel bridge is through consuming for many years, and is because of being difficult to additional wooden bridge plate again, in great short; Having is exactly to make many old longerons of making of accumulation for many years normally to use again, and idle uselessly causes waste, and has occupied parking space.
[summary of the invention]
The purpose of this utility model is can't normally use after being eliminated at the old longeron of existing steel bridge, and its transformation made a kind of new assembly type steel bridge on highway bridge plate, not only can make full use of old longeron, accomplish to make full use of the past heritage transformation, and improved structure is more firm.
The purpose of this utility model is achieved in that
The assembly type steel bridge on highway bridge plate is characterized in that bridge plate comprises underframe, is fixedly connected with panel on the underframe, and wherein underframe comprises:
Vertical at least two worker's type ribs arranging;
Vertical channel-section steel of arranging;
Vertical at least two stringers arranging.
Aforesaid assembly type steel bridge on highway bridge plate, the opening that it is characterized in that described channel-section steel be side and be provided with the curb junction plate at its lateral surface outward.
Aforesaid assembly type steel bridge on highway bridge plate, it is characterized in that described bridge plate is fixed on the highway steel bridge crossbeam by positioning and fastening arrangement, positioning and fastening arrangement comprises U-bolt, be provided with the bridge plate counterbore with the crossbeam connecting position on panel, two limbs of U-bolt link to each other with the bridge plate counterbore of both sides on the crossbeam respectively.
Aforesaid assembly type steel bridge on highway bridge plate is characterized in that being provided with above the described bridge plate several handles.
The utility model compared with prior art has following advantage:
Improve equipment, economize on resources, adopt the technical scheme of " with steel for wood ", make full use of existing old steel bridge longeron and transformed under the constant feelings portion condition of raw steel pontic system and beam structure keeping, make a kind of new assembly type steel bridge on highway bridge plate.Not only can make full use of old steel bridge longeron, accomplish to make full use of the past heritage transformation, and improved structure is more firm.Test shows, the utility model is under crawler type load and wheeled load action, its ultimate bearing capacity has all reached 2.1 times of design load, under highway-II level load, can reach fatigue life 420,000 times, satisfy the current requirement of military, civilian load fully, can improve the service time of bridge plate significantly.
