Description
Technical Field
The utility model relates to a building technical field, concretely relates to pre-buried sleeve anchor structure of girder steel encorbelments.
Background
In the high-rise building engineering construction, often need set up the scaffold frame of encorbelmenting or install the platform of encorbelmenting and hang the material at the outer wall, common way is, adopts the structure of reinforcing bar closed hoop anchor to the girder steel of encorbelmenting, perhaps adopts the structure of reinforcing bar plus angle bar anchor, and these anchor node structures have a lot of shortcomings, if: the surface of the pre-buried hoop protruding structure not only affects the field operation safety, but also is easy to deform, damage and repair, the steel beam is difficult to accurately insert into the hoop during installation, safety accidents are easy to cause, the hoop anchoring force is uncertain due to the influence of various factors such as low anchoring hoop precision and the like.
Disclosure of Invention
An object of the utility model is to the problem that above-mentioned exists with not enough, provide a pre-buried sleeve anchor structure of girder steel encorbelments, can show improvement installation accuracy, efficiency and security to realize the recovery and the multiplexing of anchor component.
In order to realize the purpose, the utility model discloses a technical scheme be:
an anchoring structure of a pre-embedded sleeve of an overhanging steel beam comprises two pairs of straight thread connecting sleeves pre-embedded in concrete of a floor slab at a certain distance, a connecting screw rod matched with the upper part of the straight thread connecting sleeve for use, an anchoring reinforcing steel bar connected with the lower part of the connecting screw rod, two steel pressing plates and a nut matched with the connecting screw rod for use, the straight thread connecting sleeve is tubular in shape, an inner cavity of the straight thread connecting sleeve is provided with an inner thread, the lower end of the connecting screw rod is provided with an outer thread matched with the inner thread of the straight thread connecting sleeve, the upper end of the anchoring reinforcing steel bar is provided with an outer thread matched with the inner thread of the straight thread connecting sleeve, the distance between the upper opening ends of the straight thread connecting sleeves pre-buried in the concrete of the floor slab is larger than the width of the cantilever steel beam, the height of the connecting screw rod which is matched with the straight thread connecting sleeve and extends out of the floor layer is greater than the height of the cantilever steel beam; and each steel pressing plate is provided with two through holes for each pair of connecting screw rods to respectively penetrate through and be locked by nuts.
Further, the upper top surface of the straight thread connecting sleeve is flush with the upper surface of the floor layer. Alternatively, the upper top surface of the straight threaded connection sleeve is higher than the upper surface of the floor layer.
In order to adapt to cantilever steel beams with different heights, a wood wedge is further included.
The utility model has the advantages that:
the utility model discloses a pre-buried two are to threaded connection sleeve and anchor reinforcing bar in the concrete of floor, and the girder steel of encorbelmenting is fixed to reuse connecting screw, steel clamp plate and nut, and the field installation is dismantled portably, and the floor plane is accessible around the installation, need not to cut unnecessary reinforcing bar head again after demolising, and connecting screw and steel clamp plate can be repeated the turnover many times and use, have both improved the installation rate, have also improved the security when installing.
