The structures such as power wall, framed-tube structure and building divide family corresponding form, if cast-in-place concrete floor construction thickness do not reach design will
Crack etc. can be caused when asking, influences the overall performance of building, the control of cast-in-situ floor concrete structure thickness at present is usually adopted
The methods of with " 50 line " method, insertion, increase thickness spacer bar method, but these methods have deficiency, are not to thickness and flat
Whole degree control is ineffective, exactly needs to increase cost.
In consideration of it, pour highly unmanageable, floor negative reinforcement and top bars position to improve traditional cast-in-situ floor
The technical problem such as it is difficult to ensure, it would be highly desirable to invent a kind of simple and effective cast-in-situ floor high accuracy positioning control system, cast-in-situ floor
Construction quality and construction efficiency.
Utility model content
It is difficult to control the purpose of this utility model is that improving traditional cast-in-situ floor and pouring height, floor negative reinforcement and upper strata
Reinforcement location such as is difficult to ensure at the technical problem, has preferable technical economic benefit.
To achieve the above object, the utility model employs following technical scheme：
Cast-in-situ floor high accuracy positioning control system, including cast-in-situ floor, negative reinforcement, top bars, bottom layer of the reinforcing steel, square tube branch
Frame, floor bottom mould, locating rod, concrete pad, Laser Line Marker and column；Concrete pad, institute are set under the bottom layer of the reinforcing steel
State square tube branch to be placed in cast-in-situ floor, locating rod is equipped with the supporting square tube in the middle part of it, the locating rod bottom sets positioning
Bar bottom plate, top set locating rod top plate, and the locating rod top plate top sets Laser Line Marker.
Further, the square tube branch is placed on floor bottom mould, and square tube stent is by longitudinal square tube, horizontal square tube and support
Square tube forms, and section is in stud, and the horizontal square tube of midfoot support square tube extended spot is equipped with square tube preformed hole, square tube preformed hole
Interior setting locating rod.
Preformed hole is set on the floor bottom mould, locating rod is equipped with preformed hole.
The locating rod bottom plate lower part sets rotation to shake hands.
The negative reinforcement is fixed on square tube stent by metal binding wire.
Concrete floor slab placement absolute altitude anchor point is set on the column, the laser rays alignment concrete floor slab placement absolute altitude that Laser Line Marker projects
Anchor point.
The utility model has the characteristics that following and beneficial effect：
(1) the utility model effectively controls the thickness that pours of cast-in-situ floor, floor by locating rod cooperation Laser Line Marker
The position of levels reinforcing bar and thickness of protection tier, while locating rod is dismountable reuses after the completion of constructing, and entirely applies
Work process is easy to operate, remarkable benefit.
(2) thickness of concrete cover can effectively ensure that by square tube stent and concrete pad, while can prevents upper strata
During floor concrete casting due to trampling position offset occurs for reinforcing bar and negative reinforcement.
(3) floor absolute altitude anchor point is set before floor concrete casting on floor two side columns, opens and swashs in casting process
Cursor line instrument can effectively control concrete floor slab placement absolute altitude.
