Description
Technical Field
The utility model relates to a fixing bolt's protective sheath, in particular to shaped steel fixing bolt's that encorbelments protective sheath that can have enough to meet need use.
Background
With the development of building construction technology, buildings grow higher and higher. In the construction process of high-rise buildings, the overhanging scaffold is widely applied. In the process of erecting the cantilever scaffold, the fixation of the cantilever section steel is a problem which cannot be avoided.
The original fixing method of cantilever section steel generally adopts the method that a U-shaped round steel hoop is directly pre-embedded on a reinforced concrete beam slab, after concrete pouring is completed and the strength is reached, the cantilever section steel is inserted into the pre-embedded hoop, and then a wood wedge is used for smashing into a gap between the hoop and the section steel; after the cantilever scaffold is used and removed, the pre-embedded U-shaped round steel hoop is cut off, and the round steel for manufacturing the hoop is wasted due to the mode. Then, pre-embedding a sleeve on the reinforced concrete beam slab, dismantling the small block bottom die of the beam slab after concrete pouring is finished and certain strength is achieved, then inversely installing U-shaped bolts, extending into a steel pressing plate and a steel base plate on the upper plane of the overhanging section steel, and finally screwing and fixing by double nuts; after the cantilever scaffold is completely removed, the nut is loosened, the U-shaped bolt is reversely drawn out, and the U-shaped bolt, the nut, the steel pressing plate and the steel base plate can be recycled; but the defects are that the reserved fixed positions of the sleeve and the steel bar framework are influenced by the force when concrete is poured and vibrated to generate deviation so as to influence the installation of the U-shaped bolt; therefore, a convenient and practical construction method for plugging the underground structure wallboard sleeve is urgently needed in a construction site.

An object of the utility model is to provide a shaped steel fixing bolt's that encorbelments protective sheath that can have enough to meet need use.
The utility model adopts the technical proposal that:
the utility model provides a shaped steel fixing bolt's that encorbelments protective sheath that can have enough to meet need use which characterized in that: the steel reinforced concrete beam slab comprises a steel reinforced concrete beam slab, U-shaped bolts and protective caps, wherein the U-shaped bolts are arranged in an installation base, the installation base is fixed on a beam slab bottom template through iron nails, the steel reinforced concrete beam slab is fixedly provided with the installation base, the steel reinforced concrete beam slab is provided with a lower layer steel mesh sheet and an upper layer steel mesh sheet, a gap in the middle of each U-shaped bolt is provided with an overhanging I-shaped steel, the bottom of the overhanging I-shaped steel is arranged on the upper surface of the steel reinforced concrete beam slab, a double-hole steel pressing plate is sleeved at the top of each U-shaped bolt, single-hole steel base plates are respectively introduced into the top ends of the two sides of each U-shaped bolt, and the single-hole steel base plates are fixed through nuts.
And a protective cap is sleeved on the top of the U-shaped bolt.
The utility model has the advantages that: the problem of fixed difficult of fixed shaped steel U-shaped bolt of encorbelmenting, reduce the pre-buried installation degree of difficulty of U-shaped bolt and strengthened the screw thread protection of U-shaped bolt is solved to establish the basis for the used repeatedly of U-shaped bolt, fully embody the universality of green construction.
