Technical field
The present invention relates to a kind of construction method of membrane shell ribbed floor formwork supporting system, belong to construction engineering technical field.
Background technology
In recent years, in the design of the volumed space buildings such as shopping square, underground garage and Structure in Shared Hall, often adopt putamina close rib building roof form of structure, to realize the large space functional requirement.But there is no the job practices of the form bracing system that meets these structure construction power transmission characteristics at present both at home and abroad, usually adopt common beam slab template supporting system job practices, not only material usage is large, long in time limit, and it is excessive that the form bracing system deformation values occurs often, even cave-in accident can occur.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of safe and reliable, economical rationality, workable construction method of membrane shell ribbed floor formwork supporting system.
The present invention is that the technical scheme that its technical problem of solution adopts is: described construction method of membrane shell ribbed floor formwork supporting system is characterized in that taking following steps:
(1) location unwrapping wire: emit the close rib of superstructure centre coordinate net in length and breadth on the vertical rod ground;
(2) set up vertical rod: the close rib of superstructure in length and breadth the crossed joint dot center of centre coordinate net set up vertical rod;
(3) set up horizon bar: eject horizon in vertical rod, then set up horizon bar, horizon bar is done reliable the connection with shear wall and frame column intersection;
(4) set up bridging: set up respectively vertical bridging continuously in the vertical rod of the vertical, horizontal center line of each row between frame column, its angle with ground is definite by 45 °~60 °;
(5) build shear wall and frame column concrete;
(6) adjustable rest is installed: the adjustable rest that diameter 30mm~40mm all is installed above every vertical rod;
(7) installation is main stupefied: the two steel pipe masters that steadily place φ 48mm * 3.0mm in the supporting plate of adjustable rest are stupefied;
(8) installation is inferior stupefied: place the lumps of wood inferior stupefied on the master is stupefied;
(9) lay panel: lay the bamboo plywood panel on the lumps of wood is time stupefied, the inferior stupefied stickfast of its seam crossing and the lumps of wood;
(10) close rib and dark Vierendeel girder reinforcing bar binding: eject close rib and dark Vierendeel girder sideline, then assembling reinforcement on panel;
(11) putamina is installed: at close rib and position, dark Vierendeel girder sideline, putamina is installed;
(12) Bars In Poured Concrete Slab reinforcing bar colligation;
(13) putamina superstructure concreting: until frame column and shear wall concrete strength, reach C20 and can build the superstructure concrete when above.
The invention has the beneficial effects as follows:
(1) meet putamina close rib building roof construction power transmission characteristics, can reach the stressed centre of form accurate, the vertical rod axial force is balanced consistent, without the best stress of secondary stress.
(2) horizon bar is connected with vertical structure, and vertical bridging continuously is set respectively in the center line vertical rod between longitudinal and transverse frame column, has increased substantially two-way lateral deformation stiffness and resistance to overturning.
(3) the longitudinal and transverse spacing of vertical rod is all arranged by the close rib crossed joint of putamina dot center, and the horizon bar first step is apart from meeting constructor's requirement of walking, and construction operation space is open, workable.
(4) compare with traditional similar support system, save vertical rod 5/9 and structure rod member 1/2, shorten floor construction cycle 1/2 left and right, meet energy-efficient green construction requirement.
The accompanying drawing explanation
Fig. 1 is the present invention's layout plan of constructing.
Fig. 2 is A-A sectional drawing in Fig. 1.
In figure: 1, the close rib of superstructure time stupefied 12, the panel 13 of stupefied 11, the lumps of wood of cross central line 8 between longitudinal centre line 7, frame column between centre coordinate net 2, vertical rod 3, horizon bar 4, shear wall 5, frame column 6, frame column, bridging 9, adjustable rest 10, two steel pipe master, putamina 14, close rib 15, dark Vierendeel girder 16, vertical rod ground in length and breadth.
