Abstract
The utility model relates to a floor slab reinforcing steel bar positioning device, which is characterized in that reinforcing steel bars are in cold bending to form the floor slab reinforcing steel bar positioning device which is a 'door'-shaped structure, a concave pocket I which supports upper reinforcing steel bars is arranged at the top of the floor slab reinforcing steel bar positioning device, supporting legs are arranged on two sides of the concave pocket I, concave pockets II for supporting lower reinforcing steel bars are disposed on the supporting legs, three to four projections are disposed on the bottom plane of the two supporting legs, the distance from each concave pocket II to the bottom plane of the supporting legs is equal to the thickness of a protecting layer, and antirust layers are coated on the projections. The reinforcing steel bars are cold drawn wires with diameters ranging from 4mm to 6mm. Compared with the prior art, the floor slab reinforcing steel bar positioning device has the advantages that 1), during construction of subdivisional work of formworks, the positioning device firmly contacts with a floor slab formwork, the thickness of the protecting layer of the lower reinforcing steel bars of a floor slab can be guaranteed effectively, 2), during construction of subdivisional work of the reinforcing steel bars, the positioning device can position the upper reinforcing steel bars of the floor slab, further can position the lower reinforcing steel bars of the floor slab and is convenient for construction, and 3), during construction of decoration work of a ceiling, the antirust layers are coated at contact positions of the positioning device and formworks, and accordingly the quality of the decoration work of the ceiling is guaranteed effectively.
Description
Technical field
The utility model relates to worker China Democratic National Construction Association field, relates in particular to a kind of floor bar positioner.
Background technology
In building engineering construction, run into the casting reinforced concrete floor through regular meeting; in the installation process of floor bar; in order to guarantee the thickness of floor bar concrete cover; generally the method for Cai Yonging is to use the marble cushion block between floor slab bottoms reinforcing bar and the template; cushion block is high in the thickness of topping; the reinforcing bar split heads that the floor upper reinforcement adopts field machining to make, or the cement mortar split heads supports.Be to guarantee rigidity requirement, the reinforcing bar split heads that field machining is made generally adopts the indented bars of diameter 12mm to make, and cost is very high, and the reinforcing bar stirrup directly contacts with template, and ceiling the rust phenomenon often occurs returning after scraping Da Bai.In addition, the reinforcing bar split heads that field machining is made can only be located the reinforcing bar of floor slab tops, and the reinforcing bar of floor slab bottoms can only support with the marble cushion block, and it is not firm to connect, and the marble cushion block often is shifted, and makes reinforcing bar contact template, can't guarantee the thickness of topping.Emerging cement mortar cushion block cost is low, but intensity is too low, does not far reach the intensity of floorslab concrete.
Summary of the invention
The purpose of this utility model provides a kind of floor bar positioner, overcomes the deficiencies in the prior art, can support floor upper reinforcement and lower rebar simultaneously, guarantees the floor slab bottoms protective layer thickness, and prevents that ceiling from returning rust.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The floor bar positioner; form by the reinforcing bar clod wash; " door " shape structure; the top is provided with a recessed pocket one that supports upper reinforcement; both sides are provided with supporting leg, and supporting leg is provided with recessed pocket two, the two supporting leg base plane that support lower rebar and is provided with 3～4 place's projectioies; recessed pocket two is a protective layer thickness with supporting leg base plane distance, is coated with on the described projection and is brushed with antirust coat.
Described reinforcing bar is the cold drawn wire of diameter 4mm～6mm.
Compared with prior art, the beneficial effects of the utility model are:
1) in the template the work items construction stage of reinforced concrete floor, it is firm that positioner contacts with slab form, can effectively guarantee the thickness of floor bottom reinforcement cover.
2) in the reinforcement installation subitem construction stage of reinforced concrete floor, positioner can be located the floor upper reinforcement, can locate underfloor reinforcing bar, convenient construction again.
3) at the ceiling decoration Construction stage, positioner and template contact position brushing antirust coat have guaranteed the quality of ceiling decoration engineering effectively.
Description of drawings

Fig. 2 is the lateral view of Fig. 1;
Fig. 3 is the utility model embodiment axis side view.
Among the figure: the recessed pocket two 6-supporting leg 7-projection of recessed pocket one 5-of 1-cold drawn wire 2-upper reinforcement 3-lower rebar 4-8-template
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, Fig. 3; it is the utility model floor bar positioner for building example structure schematic diagram; this positioner is formed by cold drawn wire 1 clod wash of diameter 4mm～6mm; " door " shape structure; the top is provided with a recessed pocket 1 that supports upper reinforcement 2, and both sides are provided with supporting leg 6, and supporting leg 6 is provided with the recessed pocket 25 that supports lower rebar 3; two supporting legs, 6 base plane are provided with 3～4 place's projectioies 7, and recessed pocket 25 is a protective layer thickness with supporting leg 6 base plane distance.
With building floor thickness is that 110mm is an example, and the antidetonation grade is a secondary, and seismic fortification intensity is 7 degree, and floor upper reinforcement 2 and lower rebar 3 diameters are the grade III steel of 8mm.Look into the architectural design atlas and know that reinforcement cover is 15mm, for guaranteeing the stability of positioner, positioner width and supporting leg width are chosen by 0.8 of height.
Calculate recessed pocket one 4 bottom level a=110-15-8=87 (mm), supporting leg 6 width b=0.8a=0.8 * 87=70 (mm), recessed pocket 25 bottom level c=15mm, supporting leg width d=0.8a=70 (mm).Can determine the total length of cold drawn wire 1 according to above-mentioned data, after making moulding on the forming machine, brush rustproof paint or spray plastics and get final product at projection 7 places that contacts with template 8 in supporting leg 6 bottoms again.
Claims (2)
1. floor bar positioner; it is characterized in that; form by the reinforcing bar clod wash; " door " shape structure, top are provided with a recessed pocket one that supports upper reinforcement, and both sides are provided with supporting leg; supporting leg is provided with the recessed pocket two that supports lower rebar; two supporting leg base plane are provided with 3～4 place's projectioies, and recessed pocket two is a protective layer thickness with supporting leg base plane distance, is coated with on the described projection and is brushed with antirust coat.
