Abstract
The utility model discloses a box-type bridge static load testing stand, which comprises two box-type lower beams and two box-type main beams, wherein connecting end frames are arranged at the ends of the two box-type amin beams, and the connecting end frames are connected with the main beams through bolts; main beam pill rod fixing bases are arranged at two ends of the main beams; lower beam pull rod fixing bases are arranged at two ends of the lower beams; a double-thread screw pull rod penetrates between each main beam pull rod fixing base and each lower beam pull rod fixing base; the maximum distance between each main beam and each lower beam is limited by each double-thread screw pull rod through nuts at two ends; four loading beams vertical to directions of the main beams are additionally arranged on the lower end faces of the main beams; and the length of each loading beam is not less than plate distance of two main beam outer boxes. The box-type bridge static load testing stand, under a precondition of satisfying testing demand, is simple in structure, light in self-weight, low in consumption of steel material and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of checkout equipment of bridge, especially a kind of static load test frame for concrete prefabricated box bridge.
Background technology
The box-shaped precast bridge that is used for high-speed railway must check its workmanship and performance parameter through static test, by the static test code requirement, the box beam of 32 meters long needs two row's loaded load, 5 load(ing) points of every row, two rows are totally 10 load(ing) points, each load(ing) point maximum load power is 140 tons, so afterburning 1400 tons of whole case beam static load, this static test need to be completed on the test stand of special use.CN201122142Y discloses a kind of prestressed concrete pre-tensioned case beam static test pedestal, this pedestal can satisfy the static test requirement of box-shaped precast bridge, but, this device need to be at the underground grade beam that huge reinforced concrete structure is set, therefore, after the Liang Chang of a place construction finished, the grade beam of building also went out of use thereupon, not only waste resource, and destroyed ecologic environment.CN201110804Y discloses a kind of Multifunctional experimental bench, this test stand is mainly pushed up by girder, entablature, sill, binder, bearing beam, pull bar, bearing and oil and forms, this test stand can move and reuse at the beam inter-plant, but, this test stand deadweight is larger, the consumption steel are more, bring inconvenience for on-the-spot handling and assembling.
The utility model content
The technical matters that utility model will solve: for above-mentioned the deficiencies in the prior art, provide a kind of box bridge static test frame, this box bridge static test frame is satisfying under the prerequisite of testing requirements, simple in structure, from heavy and light, the steel consumption amount is little, low cost of manufacture.
the technical scheme that the technical solution problem is taked: a kind of box bridge static test frame, comprise two box sills and two box type girders, be provided with the link frame in the end of two box type girders, the link frame is connected with girder by bolt, be provided with girder pull bar holder at girder two ends, be provided with sill pull bar holder at the two ends of sill, be installed with the double thread pull bar between girder pull bar holder and sill pull bar holder, the nut of double thread drawing rod via two end limits the maximum spacing of girder and sill, also be provided with five perpendicular to the loading beam of girder trend on the lower surface of girder, the length of loading beam is not less than the outer boxboard distance of two girders.
As improvement of the present utility model: described girder is connected and composed with bolt by three sections case beams of equal length.
As further improvement of the utility model: described link frame is divided into three sections, and two sections that are positioned at the outside are welded on girder, and the two ends, stage casing connect and compose the link frame by two sections, bolt and the outside.
Further improve as of the present utility model: be provided with four groups of double thread pull bars between described girder and sill, every group is made of eight double thread pull bars again.
beneficial effect: box bridge static test frame of the present utility model, owing to having adopted described two box sills and two box type girders of comprising of box bridge static test frame, be provided with the link frame in the end of two box type girders, the link frame is connected with girder by bolt, be provided with girder pull bar holder at girder two ends, be provided with sill pull bar holder at the two ends of sill, be installed with the double thread pull bar between girder pull bar holder and sill pull bar holder, the nut of double thread drawing rod via two end limits the maximum spacing of girder and sill, also be provided with five perpendicular to the loading beam of girder trend on the lower surface of girder, the length of loading beam is not less than the technical characterictic of the outer boxboard distance of two girders, by adopting the elongated loading beam design that directly the pull bar holder is set on girder and is not less than boxboard distance outside two girders, improved the torque resistant ability of girder, still can satisfy the requirement of box bridge static test after making the entablature of box bridge static test frame of the present utility model in cancelling prior art (CN201110804Y), and the every deadweight of two entablatures that reduces is wanted 10 tons at least, therefore, box bridge static test frame of the present utility model is satisfying under the prerequisite of testing requirements, simple in structure, from heavy and light, reduced the consumption of steel, reduced low cost of manufacture, due to adopted described girder by three sections case beams of equal length with the technical characterictic that bolt connects and composes, facilitated making, transportation and the on-site hoisting of girder, owing to having adopted described link frame to be divided into three sections, two sections that are positioned at the outside are welded on girder, and the two ends, stage casing have not only facilitated the installation of end frame by bolt and two sections, the outside technical characterictic that connects and composes the link frame, and shortened installation work-hour, improved installation effectiveness, be provided with four groups of double thread pull bars between described girder and sill owing to having adopted, every group of technical characterictic that is consisted of by eight double thread pull bars, make box bridge static test frame load-bearing capacity of the present utility model stronger, can stablize, complete reliably the static test of bridge.
