Description
Technical field
The present invention relates to building corridor construction technology, be specially a kind of high-altitude multilayer and dangle steel construction against way Hoisting Construction Technology.
Background technology
Current many buildings all have gallery structure, and vestibule refers generally between two or several skyscrapers by the interconnective structure of built on stilts connector, and vestibule can be used as two interface channels between building, also can be used as sight seeing and pastime purposes. Conventionally the vestibule building method adopting is first to build up two reinforced concrete structures (Ji Liangzuo building body), then between two reinforced concrete structures, from bottom to top scaffold erecting, and the structural members such as corresponding longeron, crossbeam are from bottom to top in place, finally remove again scaffold. Comparatively ripe but existing scaffold to build wastes time and energy, the larger technical problem of floor space particularly on this kind of method and technology, affect construction period, take construction site (particularly on construction ground very narrow and small time), caused construction environment severe, had a strong impact on construction efficiency.
Summary of the invention
The present invention solves scaffold in current corridor construction process to build the technical problem that floor space is large, efficiency of construction is low, provides a kind of high-altitude multilayer to dangle steel construction against way Hoisting Construction Technology.
The present invention realizes by the following technical solutions: a kind of high-altitude multilayer is dangled steel construction against way Hoisting Construction Technology, between the building body of two reinforced concrete structures in left and right of having built up, vestibule is installed, the n floor of the corresponding building of vestibule maximum layer body, the m floor of the corresponding building of the minimum one deck of vestibule body, wherein m < n; Comprise the following steps:
The first step: at n+1 floor inner side lifting first truss structure of building, left side body;
Second step: at n+1 floor inner side lifting second truss structure of building, right side body;
The 3rd step: lift main beam between already installed a pair of truss;
The 4th step: n to m layer first steel column framework is installed in suspention on main beam; Then on first steel column framework, lift n to m layer first across limit longeron; On main beam, suspention is positioned at second steel column framework after first steel column framework afterwards, between first steel column framework and second steel column framework, lifts first across a longeron; Then on main beam, suspention is positioned at the 3rd steel column framework after second steel column framework, between second steel column framework and the 3rd steel column framework, lift second across a longeron ... by that analogy, until lifted last a slice steel column framework and last across a longeron, and in the end on a slice steel column framework, lift n to m layer second across limit longeron; The both sides of all steel column frameworks are all connected with the body inner side, building of the left and right sides; All across a longeron be all connected with adjacent building body across limit longeron;
The 5th step: lift crossbeam for the first time between a pair of truss of n+1 layer;
The 6th step: n layer across a longeron between lift crossbeam for the second time; Afterwards n-1 layer across a longeron between lift crossbeam for the second time ... until complete the lifting across between a longeron crossbeam of m layer;
The 7th step: truss hoisting wind up diagonal brace and longeron;
The 8th step: lifting n+1 to m layer right side outrigger.
Vestibule steel construction of the present invention " contrary sequence method " construction is according to first top rear lower, and the construction method of first spot welding in place, the fixing rear welding of bolt location is carried out. Steel truss adopts and makes member outside the venue, and scene is assembled in advance, then uses the mode of lifting dead man and assembly pulley lifting to install; The members such as all steel columns, girder steel are all at professional produce in factory, assembled in advance, are transported to behind scene with flat truck, and truck crane is followed handling member to platform for lining. Hoisted in position adopts high-strength bolt to be connected and installed, the welding of part manual arc.
Beneficial effect of the present invention: 1, the heavy difficult point of this engineering is on-site consolidation and the hoisted in position of steel truss, analyze and in conjunction with construction experience by comprehensive study, on-the-spot Construction of Steel Structure utilization has been constructed complete and has been reached the concrete floor of label, as the platform for lining of vestibule steel member, then adopt " contrary sequence method lifting " construction method of exempting from scaffolding, first lift upper steel truss, more successively lift lower box trestle, beam and other structure are installed according to the order of " from top to bottom ". Utilize the power-equipment such as hoist engine, strand mill, the arrangement and method for construction of 2 dead man liftings completes installation.
2, in arrangement and method for construction of the present invention, the members such as steel truss, steel column framework are all at installation on ground, and the mode that adopts modular lifting to install is constructed, and has farthest reduced amount of high-altitude operation, meet the requirement of construction drawing to construction quality, reduce security protection expense and energy.
3, under the prerequisite of carrying out security protection, can ensure the continuous productive process of constructing between civil engineering and steel construction, steel construction, save working face, shorten the engineering entirety duration.
4, aspect construction costs, owing to having avoided setting up of full hall scaffold, therefore in facade, planar protective, the vertical transport of construction period, labour's input, scaffolding, close order safety net and prevent the aspects such as high falling, all can have significantly and reduce.
5, all stressed effect is clear and definite the main stressed member of steel construction and node each stage in installing engineering, meets internal force feature and the designing requirement of the steel construction that dangles.
6, without unloading operation, construction operation process simplification; Construction simultaneously finishes rear vestibule force-bearing situation and does not change, and has overcome conventional construction method and has removed the stressed technical problem that changes and cause total to deform of vestibule after the support systems such as scaffold, has ensured construction quality.
7, construction is more safe and reliable.
