Embodiment 1
[0045] Such as figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the method for carrying out the loading test on the bridge support frame by pushing the mobile prefabricated component, it includes the following steps:
[0046] 1) Place the loading special formwork 3 on the box girder formwork 2 on the bridge support frame 1 (the old formwork can be used for the loading special formwork 3);
[0047] 2) Install a plurality of rails 4 (the number of rails is 7-22) along the longitudinal direction (i.e. the length direction) of the bridge support frame 1 on the special loading template 3, and the rails 4 are fixed on the special loading template 3 with clamps The adjacent tracks are connected by special connectors (the width of the special connectors is 60mm, and the special connectors are steel belts; the tracks are equipped with double gears), and the distance between adjacent tracks is greater than the length of the prefabricated components by ...
Embodiment 2
[0067] It is basically the same as Example 1, the difference is that the bridge support frame within a certain range in the same span is subjected to a partition loading test, that is, the prefabricated components of the second floor are laid in partitions and tested in partitions, and then the bridge supports in the same span are tested. The prefabricated components in the tested area are moved to the undetected area in the same span, so as to realize the complete loading test with fewer prefabricated components.
