Abstract
The utility model relates to a prestressed concrete simply supported box girder static test self balancing counterforce frame device, which comprises a conterforce frame made up by jointing eight or seven girder components, end anchor sockets disposed on both ends of the counterforce frame; a counterforce frame supporter disposed under the counterforce frame, several distributing beams disposed on the counterforce frame, and force transmitting rods passing through the end anchor sockets. The above structure in the utility model utilizes the existing eight or seven girder components and achieves the advantages of money saving, simple in jointing and little deformation in test course.
Description
Technical field
The utility model relates to a kind of railroad bridge verifying attachment, especially relates to a kind of prestressed concrete simple supported box beam static test self-equilibrating reaction frame device.
Background technology
The large-tonnage Railway Prestressed Concrete static test of case beam simply has dual mode at present: a kind of is beam body and reaction frame and unified integral body of accessory structure formation thereof, and the deadweight of beam body and reaction frame is only born on its basis, is called self-equilibrating reaction frame system; Another kind of do not reach into a unified integral body for the beam body with reaction frame and accessory structure thereof, the load that loads in the process of the test is also born in basic deadweight of not only bearing beam body and reaction frame, is called outer balance reaction frame system.These two kinds of balanced systems all have application in present beam body static test, more extensive but the former uses, the latter because to the basis requirement than higher so use less.The common way of self-equilibrating reaction frame is by the higher patented product of designing unit's specialized designs price.And the reaction frame that my unit designs voluntarily adopts eight or the seven beam assembly units member composition of more auxiliary special processing again, its characteristics can be utilized at present existing eight or seven beams (other rod member also can), saving fund, and have assembly unit simple, characteristics such as the distortion that produces in the process of the test is little.
The utility model content
The utility model mainly is to solve above-mentioned technical matters, can effectively utilize existing eight or seven beams thereby provide a kind of, economizes on the use of funds, and assembly unit is simple, the little prestressed concrete simple supported box beam static test self-equilibrating reaction frame device of distortion in the process of the test.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: include reaction frame, described reaction frame has eight or seven beams to be spliced, be provided with the termination anchoring part at the two ends of described reaction frame, below described reaction frame, be provided with the reaction frame support, on described reaction frame, be provided with some distribution crossbeams, on the anchoring part of described termination, have transmission rod to pass through.
In the utility model, form main part of the present utility model by existing eight or seven beams.Described transmission rod links together by termination anchoring part and the fining twisted steel that is embedded in the cushion cap, constitutes a self-balancing system.Described distribution crossbeam becomes the stress point that loads lifting jack in loading procedure, and the reaction frame support plays the interim supporting role of reaction frame when Liang Shangwei loads.
As preferably, described reaction frame is made up of some rod members, gusset plate and coupling bolt, and described transmission rod is made by fining twisted steel.
In the reaction frame structure, rod member can be divided into resistance to compression beam, tension beam and support bar, and the connection between them then realizes by gusset plate and coupling bolt.
In the utility model, reaction frame utilizes eight or seven beams to form, and makes the utlity model has effectively to utilize existing eight or seven beams, economizes on the use of funds, and assembly unit is simple, the little advantage of distortion in the process of the test.

Accompanying drawing 2 is the utility model side views;
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as Fig. 1, shown in Figure 2, the utility model mainly includes reaction frame 1, described reaction frame 1 has eight or seven beams to be spliced, be provided with termination anchoring part 2 at the two ends of described reaction frame 1, on each described termination anchoring part 2, be provided with six screws, below described reaction frame 1, be provided with reaction frame support 3, on described reaction frame 1, be provided with some distribution crossbeams 4, on described termination anchoring part 2, have transmission rod 5 to pass through.Reaction frame support 3 is placed on the case beam 6.
Described reaction frame 1 is made up of rod member, gusset plate and coupling bolt, and described rod member can be divided into resistance to compression beam, tension beam and support bar, and the connection between them then realizes by gusset plate and coupling bolt.Described transmission rod 5 is made by fining twisted steel, by the screw on the termination anchoring part 2, is connected with fining twisted steel in being embedded in cushion cap, constitutes a self-balancing system.Described distribution crossbeam 4 is the stress point that loads lifting jack in loading procedure, and reaction frame support 3 plays the interim supporting role of reaction frame 1 when not loading.
