Description
Technical field
The present invention relates to construction of cast-in-situ box-beam equipment technical fields, are specially a kind of whole landing mould bases of cast-in-situ box girder.
Background technology
Fast development with country's urban construction and the continuous input to infrastructure, overpass, railway light rail bridge
Largely show.Mobile formwork is progressively popularized in beam processed construction, due to mobile formwork beam need not both build it is huge prefabricated
Liang Chang, it is not required that the fortune beam setting up girder of large-tonnage, so as to reduce a large amount of costs for building Liang Chang；Meanwhile mobile formwork system
Beam can effectively ensure that construction speed and the passability in road under bridge face from the limitation in space.But what is had to take into account that is mobile mould
The making processing cost of frame is higher, and the construction personnel of each department is needed to have higher tacit degree and allotment in the construction process
Performance is high to the competency profiling of unit in charge of construction.
When in the wild or when blocked road carries out beam processed construction, running into road surface support force preferably and need not consider construction location
When passing through performance of bridge bottom can substantially reduce cost using frame body support.But during using raft support method construction, stent sets up week
Phase is long, safety of structure is poor, frame pipe consumption is big, and stent raw material are susceptible to corrosion, deformation, cracking in circular flow
The problems such as, influence structure safety；When using the construction of such frame body complete one across after, due to itself not possessing mobility, therefore need
Again frame body is set up, it is time-consuming and laborious.There is the supporting frame that portion of techniques personnel devise ground mobile, but study carefully its essence
For, essence is to realize moving horizontally for frame body, but die sinking, the conjunction of box beam external mold by installing fixing bracket body additional mobile device
The system that mold device is carried using template is realized that, since the matching degree of the two system is poor, frame body extremely topples, sternly
Construction safety is endangered again.
The content of the invention
The present invention in order to solve in road surface support force preferably and in the case of construction location bridge bottom need not be considered by performance,
It is time-consuming and laborious using conventional frame body, it is relatively low using mobile formwork sexual valence, while lack the problem of high safety performance lands mould bases again,
Provide a kind of cast-in-situ box girder integrally landing mould bases.
