Description
Technical field
The utility model relates to a kind of morning and tears independent support band open, belongs to technical field of building construction.
Background technology
In concrete structure construction, for shortening the striking time of slab form, accelerate the turnover of the material tools such as slab form, reduce the input of building slab plate tool simultaneously, usual way is to adopt the form that early dismantling head is set to realize the early stage slab form of removing at present.Its operating principle is torn exactly plate open and is not torn supporting head open, and when floor concrete casting is after 3～4 days, concrete strength reaches 50% when above of design strength, and dismountable slab form and part support, and column is torn early head open and still kept holding state.When concrete strength reaches designing requirement, then remove whole vertical supportings.
In practical operation, early dismantling head is set and has following hidden danger at the scene:
1) because operator's technical level is uneven, often random large when early dismantling head is set, cannot guarantee that early dismantling head spacing concrete strength when form removal can meet code requirement;
2) because early dismantling head is arranged in vertical rod, with periphery vertical rod indistinction, operator often seeks convenient all vertical rods can being connected as a single entity when stripping vertical rod, remove in the lump, again support top again, so, exists serious structural safety and hidden danger of quality subsequently, do not have the effect of independent support at all, and the common existence at the construction field (site) of this phenomenon;
3) early dismantling head itself only depends on a small size iron plate to contact with concrete surface, and Area of bearing is limited.Because vertical rod is thinner, sometimes cannot become a vertical line with early dismantling head simultaneously, have a strong impact on its stressed and stability.
The utility model is based on said structure safety and hidden danger of quality, arranges early to tear independent support band open and can address the above problem.
