It is fixed；Reaction frame is two or more, and bottom plate is welded on channel steel, and the two sides on each column of reaction frame is respectively welded with an iron hook, iron
It is connected between hook with iron chains；Pedestal is used to load bearing beam piece both ends, be embedded with an iron hook respectively at the centroid of two sides；Hoist engine
It is connect by cable wire with iron hook, iron chains, pulls pedestal and reaction frame.
Further, two pieces of tetrafluoro sliding bearings are set under each pedestal, are slided convenient for pedestal.
Further, track fastener is eight or more, before the channel steel under each reaction frame is blocked using two track fasteners
Afterwards.
Further, it is embedded with reinforced mesh in basis, it is continuous downwards from the one third of I-steel bottom end to arrange four layers,
Avoid reaction frame upper group power is excessive that I-steel is caused to be extracted.
Further, rail is formed by connecting by a plurality of I-steel, and the connector between I-steel is using steel plate and is bolted.
The utility model has the advantages that
1) the utility model is by being arranged tetrafluoro slide plate in pedestal bottom and reaction frame being changed to slide rail type by ground anchor type, and
It is allowed to mobile by the traction of power device, fixed experimental provision is adapted as removable experimental provision, solves trial zone
Experimental rig builds Numerous, the high problem of economic cost.
2) position of pedestal and reaction frame is moved easily, and is solved experimental field and is needed according to the beam of different beam lengths and specially
The problem of making the experimental provisions such as pedestal and reaction frame keeps the installation of test beam and load more convenient, saves manpower object
Power reduces experimentation cost.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments:
A kind of removable packaged type bridges static-load testing device as shown in Figure 1 to Figure 3, including hoist engine 1, pedestal 2, counter-force
Frame 3, channel steel 4, rail 5, basis 6, iron hook 7, iron chains 11 and track fastener 10；Wherein basis 6 is reinforced concrete structure, is buried
Under terrace surface；Rail 5 is two i shaped steels, and the half buried foundation 6 of height, distance is greater than bridge structure between two rail 5
Part width, and set there are two pedestal 2, the length of rail 5 is respectively arranged with two hoist engines 1 to both ends；4 left-hand thread of channel steel is in rail 5
On, it can be slided on rail 5 and fixed by track fastener 10；Reaction frame 3 is two or more, and bottom plate is welded on channel steel 4, instead
Two sides on each column of power frame is respectively welded with an iron hook 7, is connected between iron hook 7 with iron chains 11；Pedestal 2 is used to load bearing beam piece two
