The present invention is a kind of technique carrying out bridge spraying using back-covered box beam spraying platform, the specific steps are：(1) use girder steel as platform skeleton, wooden frame and girder steel are attached by longitudinal paving with wooden frame, with buckle, then spread bamboo slab rubber on wooden frame, and scaffold tubes form safe enclosing on surrounding cloth, form single platform；(2) platform both ends are run through to wearing bolt；(3) surface that electronic form removal machine is moved on to pre-buried form removal hole is connected using to wearing cap to wearing, at the uniform velocity hoisting platform and fixation；(4) by the pre-buried form removal hole of twice steel wire penetrating, counter together to catch on girder steel, stabilized platform, another road is in half vacant state along box beam outer profile, hangs safety belt；(5) it is connected using bamboo slab rubber between multiple single platforms, platform ladder is set up in both sides；(6) staff enters job platform to bridge progress spraying operation.The present invention from personnel, machinery, material service life on complete upgrading, greatly reduce construction cost, improve construction efficiency.
Description
Technical field
The present invention relates to bridge spraying field more particularly to it is a kind of using back-covered box beam spraying platform progress bridge spraying
Technique.
Background technology
Qatar's east high-speed overpass concrete structure needs to carry out spraying operation after the completion of pouring, and ensures structure
Aesthetics and durability.Existing actual conditions are that there are about the bridge structures of half to be above 15m, and highest point reaches 32m.Site operation
It mostly uses bridge inspection vehicle and elevator carries out operation, or even need to set up landing stage of scaffold progress spraying operation, but due to spray
Painting workload is big, and bridge zone structural area is about 167000 square metres, and the step lasts time is long, using the high elevator of lease and sets up
The modes such as scaffold are both needed to pay huge cost, and it is more slow to construct.
Invention content
Present invention seek to address that the deficiencies in the prior art, and provides and a kind of back-covered box beam spraying platform is utilized to carry out bridge
The technique of spraying.
The present invention to achieve the above object, using following technical scheme：It is a kind of to be carried out using back-covered box beam spraying platform
The technique of bridge spraying, the specific steps are：
(1) it uses the girder steel of 3.6m to be used as platform skeleton, is bolted with 6 M16 between girder steel, longitudinally spread with the wood of 3m
Wooden frame and girder steel are attached with buckle, then spread bamboo slab rubber on wooden frame by beam, spacing 0.6m, scaffold tubes on surrounding cloth
Safe enclosing is formed, single platform is formed；
(2) run through to wearing bolt apart from the position of platform both ends 1.88m, the length to wearing bolt is 6m, to wearing bolt
Number be 4, and lock gasket and nut in base opening, the protruded length to wearing bolt is at least 50mm；
(3) surface that electronic form removal machine is moved on to pre-buried form removal hole, using to wearing cap connection to wearing, at the uniform velocity lifting is flat
Platform after reaching spraying position, using gasket and nut fixing bolt top opening, ensures that platform is firm；
(4) by the pre-buried form removal hole of twice steel wire penetrating, counter together to catch on girder steel, stabilized platform, another road is outside box beam
Profile is in half vacant state, hangs safety belt；
(5) it will be connected using bamboo slab rubber between the multiple single platforms fixed, frame hand cradle operation post ladder is set up in both sides；
(6) staff enters job platform to bridge progress spraying operation by platform ladder.
The size of the list platform is 14.4mx3m.
The gasket is filling pad.
The beneficial effects of the invention are as follows：The present invention is not take up large lifting equipment, and motor operation is simple and fast, reinforcing side
Formula is firm, and personnel do not have the security risk of working at height, lifting process not to need the auxiliary of personnel, can disposably provide a large amount of
Job platform relative to traditional elevator and sets up the processes such as the landing stage of scaffold, and safe, speed is fast, from personnel,
Complete upgrading in mechanical, material service life, greatly reduces construction cost, improves construction efficiency.
Specific implementation mode
