Abstract

The invention discloses a self-bearing oblique cantilever safe and intelligent construction system and method. The self-bearing oblique cantilever safe and intelligent construction system comprises abuilt-up structure, an oblique cantilever structure formwork, an intelligent regulation and control inhaul cable and a top end displacement measuring point support; the oblique cantilever structure formwork is installed on the built-up structure, and a plurality of side inhaul cable penetrating holes are formed in the oblique cantilever structure formwork; a local coordinate X-direction measuringpoint, a local coordinate Y-direction measuring point and a local coordinate Z-direction measuring point are arranged at the top end of the oblique cantilever structure formwork; and one end of the intelligent regulation and control inhaul cable is connected with an embedded part on the built-up structure, and the other end of the intelligent regulation and control inhaul cable is connected with the plurality of side inhaul cable penetrating holes formed in the oblique cantilever structure formwork. According to the self-bearing oblique cantilever safe and intelligent construction system, theload variable can be obtained through the flow of a concrete pump in the construction process, three-dimensional six-degree-of-freedom deformation of the vertex is conducted according to the preset conditions, the tension of the inhaul cable is automatically adjusted, and therefore the construction safety and the construction progress are further improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a safe and intelligent construction system and method for self-supporting oblique suspension. Background technique [0002] In large public buildings, the stands of some stadiums or the special shape of the building require some inclined cantilever structures. The inclined cantilever structures are different from ordinary cantilever structures. , there is not only a huge vertical force, but also a very large horizontal load. The conventional support formwork is very troublesome in the construction process, and because the platform support structure has a high resistance to vertical loads, but the resistance to horizontal thrust Very weak, especially the conventional scaffolding system, because its foundation form is floating, it is difficult to bear such a large load, which causes unsafe construction and huge consumption of manpower and material resources. ...

Problems solved by technology

[0004] The key displacement index is generally located at the apex of the formwork. In general, it is sufficient to control the vertical and horizontal displacements. However, for inclined cantilever structures, in order to further improve construction safety and construction accuracy, it is necessary not only to control the three translational freedoms at the apex of the component degree, the remaining three rotational degrees of freedom must be measured and controlled, especially the torsional degree of freedom along the axis of the component. If the torsion is too large, it will lead to the failure of the construction formwork system and cause safety accidents.
