Description
Technical Field
The utility model belongs to the technical field of the bridge construction, especially, relate to a large-scale tower crane attaches wall space steel truss basis.
Background
With the rapid advance of basic construction such as national traffic, the hoisting of large members by large tower cranes is increasing in bridge construction. The installation of steel arch bridge segment section is hung and is used cable and is just "the thread-lifting unification" scheme, and cable thread-lifting tower structural design adopts large-scale variable cross section steel pipe concrete structure more.
The height of the cable suspension buckle tower is influenced by factors such as span, ground elevation, structure distance, buckle tower foundation height, load and deformation, and the height of the buckle tower is different. Because of the variable cross-section structure, the installation difficulty of the buckling tower steel structure is larger. The traditional method is influenced by the structural form of a rod piece, dead weight, high-altitude installation and construction machines, and is poor in installation precision and low in efficiency. In order to improve the efficiency and the installation precision, a large tower crane is adopted for segmental and segmental integral hoisting. However, as the height of the tower is increased, the tower crane needs to be provided with an attached wall, the attached wall is generally connected with the tower, and the tower is used as an attached foundation.
The tower crane manufacturer generally designs the attached wall as a triangular truss structure formed by welding 3-limb angle steels, and the included angle between the attached wall and the foundation of the attached wall is generally 25-60 degrees. Most large-scale tower cranes attach to the wall and have the force points of permanent reinforced concrete structures such as the main tower of a cable-stayed bridge and the main tower of a suspension bridge, and the wall of a part of small-scale tower cranes attach to the wall by using steel pipe supports and the like, so that the force points are very easy to realize. When the existing variable-section steel truss buckling tower structure is encountered, the force points of the attached wall cannot necessarily meet the force structure requirements of the attached wall, the position is not suitable, the position of the force points of the attached wall of the tower crane exceeds the structure position along with the increase of the height, meanwhile, the tower crane needs to avoid the longitudinal displacement range generated in the hoisting process of the cable crane hoisting tower, and a certain safety distance is reserved, so that the position of the tower crane and the transverse axis of the buckling tower are not on the same line and are on the side edge of the longitudinal hoisting position in order to ensure the maximum hoisting weight; the tower crane attaches the wall because tower crane positional deviation, attach the wall quantity (detain the tower and set up with higher and attach the wall more), attach the wall contained angle requirement, variable cross section truss etc. factor, the tower crane attach the wall basis can be along with detaining the tower height and increase, partly basic cantilever goes out and detains the tower structure outside, and higher skew is big more, and what appeared the tower crane attaches the wall and detains the tower structure with the steel truss and be connected and can appear not satisfying and attach the wall and support the problem of biography power. If the proper triangular truss cannot bear great force, the tower buckling rod piece deforms when the force is too large, and accidents of the tower crane in the hoisting process are easily caused.
