According to code requirement, it is 1000mm that dowel 40 calculates anchorage length, and built-in fitting 10 overall heights reach 1036mm, exceed the height of reinforced concrete beam 20.To this, the way that adds 90 degree crotches 50 with regard to adopting in dowel 40 bottoms is strengthened anchoring, wherein straight section length 600mm, crotch length 400mm.Construction stage, because of construction period contradiction between two specialties, before built-in fitting 10 is marched into the arena, the reinforcing cage of reinforced concrete beam 20 colligation completes, and job site reflects that former design built-in fitting 10 cannot construct.
Because steel work and concrete structure adhere to Liang Zhi professional construction troop separately, the built-in fitting of steel work is generally transported to on-the-spot installation again making in factory after integral manufacturing, and the construction continuity of concrete specialty is very strong.Once there is contradiction on the duration, its result often built-in fitting 10 place's reinforced concrete members reinforcing cage colligation complete, the built-in fitting 10 of steel work is marched into the arena just now, now in face of thickly dotted reinforcing bar, the crotch 50 of dowel 40 bottoms just becomes the great obstacle of installation of embedded parts, way specification, the reinforcing bar of concrete specialty is prized curved one by one, reinforcing bar gap in increase reinforcing cage is to meet dowel interpolation, time-consuming self-evident, way is nonstandard, directly the crotch of dowel bottom is cut off, and buries on the spot potential safety hazard.
Therefore, in the situation that dowel anchorage length is subject to reinforced concrete member thickness limits, the flat built-in fitting of construction steel structure specialty needs one more reasonably to construct, can rationally shorten the anchorage length of dowel, can evade again two crossed construction contradictions between specialty, reduce the construction and installation difficulty of built-in fitting, prevent barbarous construction, therefore this case produces.
Utility model content
The purpose of this utility model is a kind of flat built-in fitting, in the situation that dowel anchorage length is subject to concrete component thickness limits, can rationally shorten the anchorage length of dowel, can evade again crossed construction contradiction between steel work specialty and concrete specialty, reduce the construction and installation difficulty of built-in fitting.
In order to achieve the above object, technical solution of the present utility model is:
A kind of flat built-in fitting, comprises anchor slab, some dowels, some anchoring mechanisms; On anchor slab, weld some dowels, dowel end forms anchoring mechanism.
