Description

Flower basket bolt scaffold frame of encorbelmenting Technical Field The utility model relates to the technical field of building construction, in particular to a basket bolt overhanging scaffold. Background In the field of modern building construction, with the continuous increase of building height and the increasing complexity of building modeling, the demand for external scaffold is also increasing. The outer scaffold is used as a temporary support and operation platform structure which is indispensable in the building construction process, and the performance and the safety of the outer scaffold are directly related to the life safety of constructors and the smooth progress of engineering. The overhanging scaffold is widely applied to the construction of high-rise buildings and some special building structures because of being capable of providing a working platform for facade construction without occupying the internal space of the building. The connection mode between the cantilever beam and the main structure of the building of the traditional cantilever scaffold often has defects. For example, some adopt simple pre-buried bolt or welded connection's mode, bear construction load and perhaps the external force effect such as wind load, seismic load that receive for a long time, the connection position appears the condition of becoming flexible, deformation even fracture easily. This not only affects the overall stability of the scaffold, but may also lead to safety accidents. When building construction is carried out in strong wind areas, the wind resistance of the existing overhanging scaffold often cannot meet the requirements. Under the action of wind load, the traditional structure can generate larger shaking and deformation due to the limitation of the structure form and the connection mode. The shaking and deformation not only can influence the normal operation of constructors, but also can lead the components of the scaffold to be subjected to additional fatigue load, shorten the service life of the scaffold and increase potential safety hazards. Disclosure of utility model The utility model aims to provide a flower basket bolt overhanging scaffold, which comprises an overhanging girder, a frame body structure and a pull rod assembly, wherein one end of the overhanging girder is anchored on an overhanging layer by a high-strength bolt, the other end of the overhanging girder is provided with a lifting lug plate, the pull rod assembly is connected with a steel pull rod, the lifting lug plate and a pre-embedded lifting ring by a flower basket bolt to form an adjustable triangular stress system, the length of the pull rod can be adjusted, the load can be dispersed, one end of the frame body structure is supported on the triangular system, the other end of the frame body structure is connected with a wall body by a wall connecting piece, a double stable structure is formed, the load can be effectively transmitted, the anti-overturning capacity is enhanced, and the construction safety and the platform stability are ensured. The utility model is realized by the following technical scheme: The flower basket bolt overhanging scaffold comprises an overhanging main beam, a frame body structure and a pull rod assembly, wherein the overhanging main beam comprises I-steel, one end of the I-steel is anchored on an overhanging layer through a high-strength bolt, and the other end of the I-steel is provided with a lifting lug plate; The pull rod assembly comprises a basket bolt and a steel pull rod, and the steel pull rod is respectively connected with the lifting lug plate and the pull rod layer embedded lifting ring through the basket bolt to form an adjustable triangular stress system; one end of the frame structure is erected on the triangular stress system, and the other end of the frame structure is connected with the wall body through a wall connecting piece. In this scheme, anchor in layer major structure roof beam of encorbelmenting through encorbelmenting girder one end and utilize high-strength bolt anchor, the other end sets up the lug board and provides the pull rod connected node, ensure the anchoring strength and the stability of overhanging basis, the pull rod subassembly passes through basket bolt connection steel pull rod and lug board and the pre-buried rings in upper strata, form adjustable triangle-shaped atress system, accessible basket bolt's elasticity regulation pull rod length, realize the dynamic adjustment to the girder stress state of encorbelmenting, disperse construction load and wind load are to the effect of encorbelmenting structure, promote whole anti-overturning ability, and support body structure one end in triangle-shaped atress system, make cantilever beam and pull rod form stable fulcrum, the other end passes through even wall spare and wall body rigid connection, form "cantilever support+rigid tie"'s dual stable structure, both utilize triangle-shaped mechanics princip
