Detachable overhung steel beam pre-buried fixing device with horizontal fixing assembly

Abstract

The invention discloses a detachable overhung steel beam pre-buried fixing device with a horizontal fixing assembly. The detachable overhung steel beam pre-buried fixing device comprises an overhung steel beam, a concrete structural member, the horizontal fixing assembly, a pressing plate, a bottom plate, at least two screws and first nuts matched with the screws respectively in a threaded mode. The screws are arranged on the two sides of the overhung steel beam and are vertically arranged at intervals, one end of the horizontal fixing assembly is detachably connected with the screws, the other end of the horizontal fixing assembly abuts against and is matched with the side face of the overhung steel beam in the horizontal direction, the lower portions of the screws and the bottom plate are pre-buried in the concrete structural member, the bottom ends of the screws are fixed to the bottom plate, the top ends of the screws are locked and connected with the first nuts in a threaded mode after penetrating through the pressing plate, the pressing plate abuts against and is matched with the top end of the overhung steel beam in the vertical direction, and the concrete structural member abuts against and is matched with the bottom end of the overhung steel beam in the vertical direction. The overhung steel beam is fixed in the horizontal direction and is convenient to assemble and disassemble and can be repeatedly used conveniently.

Description

Technical field [0001] The invention relates to a fixing device for a cantilevered steel beam, in particular to a detachable cantilevered steel beam pre-buried fixing device containing a horizontal fixing component. Background technique [0002] With the rapid development of modern construction industry, urban mid-to-high-rise buildings have become the main buildings. Profile steel cantilever scaffolding is one of the main types of scaffolding. With the continuous promotion of green construction concepts and the increasing importance of green construction technology, the The demand for green construction technology for scaffolding is increasing. [0003] Traditional external scaffolding cantilever steel beams are sawn into a wedge shape with wooden beams, and inserted between the cantilever steel beams and the embedded parts to prevent horizontal movement of the I-beam.

Problems solved by technology

[0003] The cantilevered steel beams of the traditional external scaffolding are sawn into wedges by wooden beams and inserted between the cantilevered steel beams and the embedded parts to prevent the horizontal movement of the I-beams. This method will cause waste of wooden beams and is not conducive to On-site civilized construction

Workers are often more casual when operating on site, and the wooden beams are not cut into wedge shapes, and the wooden beams are inserted between the cantilevered steel beams and the embedded parts and are not tapped tightly, resulting in a gap between the cantilevered steel beams and the embedded parts. The stuffed wooden beams often cannot be fixed in the horizontal direction, so that the cantilevered steel beams still have the risk of swinging in the horizontal direction, which in turn affects the stability of the entire outer frame system

In addition, in the traditional method, the U-shaped steel bar pull ring is used as the embedded part of the steel beam, which cannot be recycled repeatedly, which increases the cost investment, and has a certain pollution to the environment, which is not environmentally friendly.
