Abstract
The invention discloses a box type bridge static loading test rack. The box type bridge static loading test rack comprises two box type lower transverse beams and two box type main beams; connecting end racks are arranged at the two ends of the two box type main beams; the connecting end racks are connected with the main beams through bolts; main beam pull rod fixing bases are arranged at the two ends of the main beams; lower transverse bean pull rod fixing bases are arranged at the two ends of the lower transverse beams; a double-ended thread pull rod penetrates through between the main beam pull rod fixing bases and the lower transverse bean pull rod fixing bases; the maximum distance between the main beams and the lower transverse beams is limited through nuts at the two ends of the double-ended thread pull rod; five loading beams which are vertical to the directions of the main beams are further arranged on the lower end faces of the main beams; and the length of the loading beams is not less than the distance between the outer box plates of the two main beams. The box type bridge static loading test rack has the advantages of simple structure, light self weight, small steel material consumption amount and low manufacturing cost on the premise of meeting test requirements.
Description
Technical field
The present invention 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, 32 meters long box beam 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 finished at 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 a Liang Chang of 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 mainly is comprised of girder, entablature, sill, binder, bearing beam, pull bar, bearing and oil top, 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.
Summary of the invention
The technical matters that invention 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, and is simple in structure, and 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 the girder two ends, be provided with sill pull bar holder at the two ends of sill, between girder pull bar holder and sill pull bar holder, be installed with the double thread pull bar, 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 invention: described girder is connected and composed with bolt by three sections case beams of equal length.
As a further improvement on the present invention: described link frame is divided into three sections, and two sections that are positioned at the outside are welded on the girder, and the two ends, stage casing connect and compose the link frame by two sections in bolt and the outside.
Further improve as of the present invention: 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 invention, owing to 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 the girder two ends, be provided with sill pull bar holder at the two ends of sill, between girder pull bar holder and sill pull bar holder, be installed with the double thread pull bar, the nut of double thread drawing rod via two end limits the maximum spacing of girder and sill, on the lower surface of girder, also be provided with five perpendicular to the loading beam of girder trend, the length of loading beam is not less than the technical characterictic of the outer boxboard distance of two girders, the pull bar holder is set and is not less than that the elongated loading beam of boxboard distance designs two girders outside by adopting directly at girder, improved the torque resistant ability of girder, so that still can satisfy the requirement of box bridge static test behind the entablature of box bridge static test frame of the present invention in cancellation 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 invention is satisfying under the prerequisite of testing requirements, simple in structure, from heavy and light, reduce the consumption of steel, reduced low cost of manufacture; Since adopted described girder by three sections case beams of equal length with the technical characterictic that bolt connects and composes, made things convenient for making, transportation and the on-site hoisting of girder; Owing to adopted described link frame to be divided into three sections, two sections that are positioned at the outside are welded on the girder, and the two ends, stage casing have not only made things convenient for the installation of end frame by two sections technical characterictics that connect and compose the link frame of bolt and the outside, and shortened installation work-hour, improved installation effectiveness; Owing to adopted and be provided with four groups of double thread pull bars between described girder and sill, 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 invention stronger, can stablize, finish reliably the static test of bridge.
