Description
Technical field
The present invention relates to construction of cast-in-situ box-beam equipment technical field, the whole landing mould bases of specially a kind of cast-in-situ box girder.
Background technique
With the fast development of country's urban construction and the continuous investment to infrastructure, overpass, railway light rail bridge
Largely show.Mobile formwork is gradually popularized in beam processed construction, due to mobile formwork beam both do not need to build it is huge prefabricated
Liang Chang does not need the fortune beam setting up girder of large-tonnage yet, to reduce the cost of a large amount of construction Liang Chang；Meanwhile mobile formwork system
Beam is not limited by space, can effectively ensure that the passability of construction speed and road under bridge face.But what is had to take into account that is mobile mould
The production processing cost of frame is higher, and the construction personnel of each department is needed to have higher tacit agreement degree and allotment in the construction process
Performance is high to the competency profiling of unit in charge of construction.
When carrying out beam processed construction in field or blocked road, road surface support force is encountered preferably and without considering construction location
When the passage capacity at bridge bottom, cost can be substantially reduced using frame body support.But when using raft support method construction, bracket sets up week
Phase is long, safety of structure is poor, frame pipe consumption is big, and bracket raw material are easy to appear 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 having a mobility, therefore need
Again frame body is set up, it is time-consuming and laborious.There are portion of techniques personnel to devise the supporting frame of ground mobile, but studies 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
Mold device is realized that, since the matching degree of the two system is poor, frame body extremely topples, sternly using the system that template carries
Construction safety is endangered again.
Summary of the invention
The present invention in order to solve road surface support force preferably and without consider construction location bridge bottom passage capacity in the case where,
It is time-consuming and laborious using conventional frame body, it is lower using mobile formwork sexual valence, while lacking the problem of high safety performance lands mould bases again,
Provide a kind of cast-in-situ box girder entirety landing mould bases.
