Description
Technical field
The present invention relates to building corridor construction technology, be specially a kind of high-altitude multilayer pendency steel work Counter procedure Hoisting Construction Technology.
Background technology
Current many buildings all have gallery structure, and vestibule refers generally to by the interconnective structure of built on stilts connector between two or several highrise buildings, and vestibule can be used as the interface channel between two buildings, also can be used as sight seeing and pastime purposes.The vestibule building method of usual employing first builds up two reinforced concrete structures (Ji Liangzuo building body), then from bottom to top scaffold erecting between two reinforced concrete structures, and the structural members such as corresponding longeron, crossbeam are from bottom to top in place, finally remove scaffold again.On this kind of method and technology comparatively ripe but exist scaffold build waste time and energy, technical problem that particularly floor space is larger, have impact on construction period, occupy construction plant (particularly on construction ground very narrow and small time), cause 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 pendency steel work Counter procedure Hoisting Construction Technology.
The present invention realizes by the following technical solutions: a kind of high-altitude multilayer pendency steel work Counter procedure Hoisting Construction Technology, between the building body of two reinforced concrete structures in left and right built up, vestibule is installed, the n-th layer of vestibule maximum layer corresponding building body, the m floor of the minimum one deck of vestibule corresponding building body, wherein m<n; Comprise the following steps:
The first step: at (n+1)th floor inner side lifting the first truss structure of building, left side body;
Second step: at (n+1)th floor inner side lifting the second truss structure of building, right side body;
3rd step: lift main beam between already installed a pair truss;
4th step: suspended fixing n to m layer first steel column framework on main beam; Then on first steel column framework, n to m layer first is lifted across limit longeron; On main beam, suspended fixing is positioned at second steel column framework after first steel column framework afterwards, lifts first across a longeron between first steel column framework and second steel column framework; Then on main beam, suspended fixing is positioned at the 3rd steel column framework after second steel column framework, second is lifted across a longeron between second steel column framework and the 3rd steel column framework ... by that analogy, until lifted last a slice steel column framework and last across a longeron, and in the end a slice steel column framework lifts n to m layer second across limit longeron; The both sides of all steel column frameworks all with inside the building body of the left and right sides are connected; Allly all to be connected with adjacent building body with across limit longeron across a longeron;
5th step: lifting first time crossbeam between a pair truss of (n+1)th layer;
6th step: n-th layer across a longeron between lifting second time crossbeam; Afterwards (n-1)th layer across a longeron between lifting second time crossbeam ... until complete the lifting across between a longeron crossbeam of m layer;
7th step: truss hoisting winds up diagonal brace and longeron;
8th step: outrigger on the right side of lifting n+1 to m layer.
Vestibule steel work " contrary sequence method " construction of the present invention is according to first top rear lower, and the construction method that rear welding location is fixed in first spot welding in place, bolt is carried out.Steel truss adopts and makes component outside the venue, and scene is assembled in advance, and the mode then using lifting dead man and assembly pulley to lift by crane is installed; The components such as all steel columns, girder steel all professional factory make, assembled in advance, after being transported to scene with flat truck, mobile crane follow load and unload component to platform for lining.Hoisted in position adopts high-strength bolt connection, and part manual arc welds.
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, to be analyzed by comprehensive study and in conjunction with construction experience, on-the-spot Construction of Steel Structure utilizes has constructed complete and has reached the concrete floor of label, as the platform for lining of vestibule steel beam column, then " contrary sequence method lifting " construction method exempting from scaffolding is adopted, first lift upper steel truss, more successively lift installation lower box trestle, beam and other structure according to the order of " from top to bottom ".Utilize the power-equipment such as hoist engine, strand mill, the constructure scheme of 2 dead man liftings completes installation.
2, in constructure scheme of the present invention, the components such as steel truss, steel column framework are all at installation on ground, and the mode adopting modular lifting to install is constructed, and farthest decreases amount of high-altitude operation, meet the requirement of construction drawing to workmanship, reduce security protection expense and energy.
3, under the prerequisite carrying out security protection, the continuous productive process of constructing between civil engineering and steel work, steel work can be ensured, save work plane, shorten the engineering overall duration.
4, in construction costs, owing to avoiding setting up of full hall scaffold, therefore construction period, labour's input, scaffolding, close order safety net facade, planar protective, vertical transport and prevent from, in high falling etc., all having and reduce significantly.
5, all stressed effect of the main stressed member of steel work and node each stage in installing engineering is clear and definite, meets internal force feature and the designing requirement of pendency steel work.
6, without unloading operation, construction operation process simplification; Construction simultaneously terminates rear vestibule force-bearing situation and does not change, and overcomes conventional construction method and removes the stressed technical problem causing total to deform that changes of vestibule after the support systems such as scaffold, ensure that workmanship.
7, construction is more safe and reliable.
