Description

A kind of morning tears independent support band open
Technical field
The present invention relates to and tear independent support band open a kind of morning, belong to technical field of building construction.
Background technology
In concrete structure construction, for shortening the striking time of slab form, accelerating the turnover of the material tools such as slab form, reducing the input of building slab plate tool simultaneously, current usual way adopts the form arranging early dismantling head to realize removing slab form in early days.Its operating principle is torn plate exactly open and is not torn supporting head open, and when floor concrete casting is after 3 ~ 4 days, when concrete strength reaches more than 50% of design strength, namely dismountable slab form and part support, and column is torn head early open and still kept holding state.When concrete strength reaches designing requirement, then remove whole vertical supporting.
Can, at the scene in practical operation, early dismantling head be set and there is following hidden danger:
1) because operator's technical level is uneven, often random large when arranging early dismantling head, cannot ensure 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 and 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 more subsequently, so, also exists serious structural safety and hidden danger of quality, 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 contacts with concrete surface by one piece of small size iron plate, and Area of bearing is limited.Simultaneously because vertical rod is comparatively thin, sometimes cannot become a vertical line with early dismantling head, have a strong impact on its stressed and stability.
The present invention is based on said structure safety and hidden danger of quality, arrange and early tear independent support band open and can solve the problem.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of spacing criterion settings, independent support, the morning of firm supporting tears independent support band open.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of morning tears independent support band open, for the early-dismantling device of several parallel arrangements, described early-dismantling device comprises: bracing members, standard keel and keelson, it is characterized in that: also comprise top plate supporting head, junction plate and connection rib, described top plate supporting head lower end is connected with described bracing members, a described top plate supporting left and right two ends by described junction plate be connected rib and be connected with described standard keel and keelson respectively.
