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 and not enough of the aforesaid existence, provide a pre-buried tapered thread sleeve anchor structure, 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 for the pre-embedded conic sleeve of cantilever steel beam is composed of a sleeve body consisting of a sleeve body and a sleeve core
The concrete floor slab comprises two pairs of conical threaded sleeves, connecting screws, nuts and two steel pressing plates, wherein the two pairs of conical threaded sleeves are arranged in the concrete of a floor slab, the connecting screws are matched with the conical threaded sleeves, the nuts are matched with the connecting screws, the conical threaded sleeves are in a conical shape with a small top and a large bottom, the upper ends of the conical threaded sleeves are provided with openings and internal threads, the lower ends of the connecting screws are provided with external threads matched with the internal threads of the conical threaded sleeves, the distance between the upper opening ends of each pair of conical threaded sleeves embedded in the concrete of the floor slab is larger than the width of an overhanging steel beam, and the height of the connecting screws, which are matched with the conical threaded sleeves, extending out of a floor layer is larger than the height of the overhanging steel beam; and each steel pressing plate is provided with two through holes for each pair of connecting screw rods to pass through respectively.
Further, the internal thread of the conical threaded sleeve is arranged on the upper section of the conical threaded sleeve, and the height of the internal thread is 1/5-1/2 of the height of the conical threaded sleeve. Alternatively, the length of the internal thread of the tapered threaded sleeve exceeds 1/2 the length of the tapered threaded sleeve.
Further, the upper top surface of the tapered threaded sleeve is flush with the upper surface of the floor layer. The upper top surface of the tapered threaded 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 pairs of tapered threaded sleeves in the concrete of floor, reuse connecting screw, steel clamp plate and nut and come the fixed girder steel of encorbelmenting, both improved the installation rate, also improved the security when installing, reduce the anchor component and damage, guaranteed the precision, conveniently retrieve, reduced the man-hour and the expense of maintenance.
