Description
Technical field
The present invention relates to technical field of bridge engineering more particularly to a kind of end template integral hoisting methods.
Background technology
Commonly used cast-in-situ box girder structure is the bridge box and beam structure within 150m, and it is prefabricated that the country mostly uses single span single-unit
The structure of installation, being influenced by region limitation, prefabricated fabricating yard limitation etc. due to, cast-in-situ box girder structure may be used,
Cast-in-situ box girder is also the structure applied to science of bridge building, especially in the case where place is limited or complex environment, cast-in-place afterward stretch box beam
Using will be more and more.
It needs to use end template during cast-in-place afterward stretch box beam, end template is the basis of cast-in-situ box girder technology, good
Bed die plate technique determines the engineering design of cast-in-situ box girder technology, working procedure, construction budget etc..So end template engineering
Construction technology is most important, it is concerning the quality to whole building engineering.
Originally, end template engineering is that concrete blinding not only expends material, also delay engineering because it cannot be recycled
The time of construction, labor intensive and material resources.Early in the twentieth century, there is assembled sizing plank sheathing, be conducive to making again for template
With, so that the development of template is had big leap, it is subsequent machine-building occur again, thus instead of handmade, greatly save
Time, in the 1960s, there is Combined type sizing template.Later, with the gradual development of end template engineering technology,
The technology of end template engineering is also more and more ripe, keeps engineering construction more flexible.
End template engineering technology mostly uses the raw materials group such as timber, steel plate and glued board and builds up panel body system and support system.
After engineering, which is then needed to be removed using long crowbar, only from project cost, the engineering is just
The 15-30% of overall cost is accounted for, which has a very important role for whole bridge construction engineering.
End template engineering technology will meet building foundation requirement, need to keep building from installation quality, when installation
Shape and position, it is ensured that sealing not spillage；From security performance, bearing capacity, rigidity and stability are taken into account；From economy
From the point of view of angle, need to meet assembly and disassembly simplicity, nonexpondable requirement.
For 33 construction of cast-in-situ box-beam, quantities is huge, if scene carries out the assembly of bed die after having set up scaffold,
Construction safety restraining factors are big, inefficiency.
