Art scheme, cushion block or support member are placed in template, spacer bar, this kind of scheme existing defects, can not such as be limited on reinforcing bar
Floating, unrestricted to moving horizontally, reliability is less high.
In close rib building roof, girt strip size and bottom steel bar stress position are more important, also lack easier at present and do
Method.In addition, for the close rib building roof containing components such as filling block, permanent templates, its template system also commonly uses full hall support, full paving
The a large amount of live aerial work of the needs such as steel form or glued board, formwork and installation form or filling block, efficiency is low, and security is poor.
The content of the invention
It is an object of the present invention to provide keeper, the keeper can make girt strip size and reinforcement location accurately may be used
Lean on；
Second object of the present invention is to provide the close rib building roof using keeper, the convenient, bottom of close rib building roof construction
Smooth, low cost.
Third object of the present invention is to provide the close rib building roof construction formwork system using keeper, the construction formwork system
System is succinct reliably, aerial work is few.
Keeper of the present invention, the technical scheme adopted is that including fixed steel bars part, limiting component and self poisoning structure
Make, fixed steel bars part is buckle, the collar, fastens hole or tie up silk, and limiting component is gear leg or rib or blend stop or block, and itself is solid
Fixed construction is the lower logical screw or hole clipping set on gear leg or leg or base end face.
The features of the present invention also resides in,
Also include horizontal support, fixed steel bars part is arranged in horizontal support；Two gear legs are located at horizontal support both ends, its spacing root respectively
Determined according to girt strip size, screw or hole clipping are positioned at gear leg bottom, or leg, logical spiral shell under being set on leg are set in gear leg bottom
Hole b or nut b；Keeper is steel part.
Also include horizontal support, horizontal support is connected on base, and fixed steel bars part is arranged in horizontal support, and bottom surface of support saddle is provided with lower logical
Screw or hole clipping, block or blend stop are arranged on horizontal support both ends.
The present invention uses the close rib building roof of keeper, the technical scheme adopted is that including girt strip, top panel and permanent mould
The side wall of plate or filling block, permanent template or filling block is the side form or/and superposed surfaces of girt strip, and girt strip bottom is also containing positioning
Part, keeper limit permanent template or the spacing of filling block or position and fixed girt strip bottom and indulge muscle.
The features of the present invention also resides in,
Permanent template is gypsum hollow lath or cement light-weight aggregate hollow lath, and hollow lath is provided with multiple elongated core pullings
Hole, core pulling hole is provided with plug, or is reduced into aperture a at one end；Hollow lath contains enhancing muscle or enhancing net.
Filling block is gypsum block, air-entrained concrete building block, concrete hollow block or sintered hollow building block.
At least contain a dark outrigger at the supporting of superstructure, dark outrigger is steel part, and parts rest is in supporting superstructure
On girder steel or Prefabricated Concrete beam or wall, outside bearing near, provided with lower logical screw or nut c.
Permanent template or filling block top surface are additionally provided with depression bar, and depression bar is fixed on girt strip reinforcing bar or keeper.
The present invention uses the construction formwork system of keeper, the technical scheme adopted is that including joist and permanent template
Or filling block, in addition to keeper, multiple keepers are arranged at intervals, by can the fastener of bottom dismounting be fixed on joist top surface,
The interval of the limiting component restriction permanent template of keeper or spacing or the position of filling block, permanent template or filling block forms rib
Beam form chamber.
The features of the present invention also resides in,
Permanent template is gypsum hollow lath or cement light-weight aggregate hollow lath, and hollow lath is provided with multiple elongated core pullings
