Description

Putamina close rib building roof form bracing system job practices
Technical field
The present invention relates to a kind of putamina close rib building roof form bracing system job practices, belong to construction engineering technical field.
Background technology
In recent years, in the design of 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 the job practices of still not having 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 big, and is long in time limit; And it is excessive that the form bracing system deformation values takes place often, even cave-in accident can take place.
Summary of the invention
The technical problem that the present invention will solve is: provide a kind of safe and reliable, economical rationality, workable putamina close rib building roof form bracing system job practices.
The technical scheme that the present invention is adopted for its technical problem of solution is: described putamina close rib building roof form bracing system job practices is characterized in that taking following steps:
(1) location unwrapping wire: on the vertical rod ground, emit the close rib of superstructure centre coordinate net in length and breadth;
(2) set up vertical rod: the close rib of superstructure in length and breadth the cross node center of centre coordinate net set up vertical rod;
(3) set up horizon bar: in vertical rod, eject horizon, set up horizon bar then, horizon bar is done reliable the connection with shear wall and frame column intersection;
(4) set up bridging: in the vertical rod of the vertical, horizontal center line of each row between frame column, set up vertical bridging continuously respectively, 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 in the supporting plate of adjustable rest, steadily place φ 48mm * 3.0mm are stupefied;
(8) installation is inferior stupefied: it is inferior stupefied on the master is stupefied, to place the lumps of wood;
(9) lay panel: on the lumps of wood is time stupefied, lay the bamboo plywood panel, the inferior stupefied stickfast of its seam crossing and the lumps of wood;
(10) close rib and dark Vierendeel girder reinforcing bar binding: on panel, eject close rib and dark Vierendeel girder sideline, assembling reinforcement then;
(11) putamina is installed: putamina is installed at close rib and position, dark Vierendeel girder sideline;
(12) cast-in-place slab muscle colligation;
(13) putamina superstructure concreting: treat that 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, it is accurate to reach the stressed centre of form, and the vertical rod axial force is balanced consistent, does not have the best stress of secondary stress.
(2) horizon bar is connected with vertical structure, and in the center line vertical rod between vertical, the crossing frame post vertical bridging continuously is set respectively, has increased substantially two-way lateral deformation stiffness and resistance to overturning.
(3) vertical, the horizontal spacing of vertical rod is all arranged by the close rib cross of putamina node center, and horizon bar first step distance satisfies constructor's requirement of walking, and construction operation space is open, and is workable.
(4) compare with traditional similar support system, practice thrift vertical rod 5/9 and structure rod member 1/2, shorten the floor construction cycle about 1/2, meet energy-efficient green construction requirement.
