Description

Attached lifting scaffold machine position fixing device at overhanging component

Technical Field

The utility model relates to the technical field of building construction, in particular to a lifting scaffold machine position fixing device attached to an overhanging component.

Background

The climbing frame is firmly connected to the building structure by means of attachment supports for supporting the self weight and the load generated in the construction process, and the attachment supports are firmly installed on structural components such as columns, beams, walls and the like of the building by means of connecting pieces such as screws, nuts and the like.

However, since the external profile design of the building is often complex and variable, the attachment support of the climbing frame may encounter an overhanging structure extending outwards, such as a balcony, a canopy, etc. when being installed. The climbing frame machine position is used as a key supporting point of an outer scaffold of a high-rise building, and the stability and the safety of the climbing frame machine position are directly related to the smooth progress of the whole construction process and the life safety of field operation personnel. Conventionally, as shown in fig. 5, the climbing frame machine is often directly fixed on the edge-sealing secondary beam of the overhanging component of the building by embedding a wall-penetrating bolt. However, although this mounting method is seemingly simple, there is a considerable potential safety hazard in practice.

In particular, when the climbing frame machine is only attached to the edge sealing secondary beam of the overhanging component, rather than being arranged on the more stable inner frame beam or the connecting beam, the stress mode is single and concentrated. Because the edge banding secondary beam is generally lower in design bearing capacity and shear strength compared with an inner frame beam or a connecting beam, the edge banding secondary beam is extremely easy to deform or damage under the action of bearing the climbing frame and construction load above the climbing frame.

More seriously, the stress mode can also cause structural problems such as cracking and the like at the root of the overhanging component. Because of the concentrated load generated by the climbing frame machine, the root of the overhanging component can be subjected to additional bending moment and shearing force, so that the risk of root cracking is increased. Once the root cracks, the safety of the whole structure of the building is seriously affected, and more serious safety accidents can be caused.
