Background
In the field of building construction, a steel bar split heads is one of indispensable workpieces in a reinforced concrete structure. In cast-in-place planar structures, such as floors, the upper reinforcing bars are in a floating state, and the positions of the upper reinforcing bars determine the bearing capacity of the floors. The split heads are used for fixing the upper layer of steel bars, preventing the steel bars from deforming and shifting and playing a supporting role. The traditional steel bar split heads are made of steel bars, the shapes of the traditional steel bar split heads mainly comprise a square shape, an A shape, a cross shape, an I shape, a triangle shape and the like, the shapes are various, the square shape is most commonly used, the manufacturing is simple, the using effect is not ideal, the cross shape effect is optimal, and a stub bar is used but electric welding is needed. Traditional reinforcing bar split heads are disposable split heads, and after concrete floor poured, the split heads only must remain in the floor, extravagant material. Under the requirements of construction concepts of cost reduction, energy conservation, environmental protection, green construction and the like, a novel split heads is needed to solve the problem.
Disclosure of Invention
In order to solve the problem, the utility model discloses a reinforcing bar split heads can have enough to meet need to come up formula can have enough to meet need used repeatedly, and material saving reduces engineering cost, through establishing the scale mark on the landing leg in addition, can realize pouring the time control to floor thickness.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides an on floating can have enough to meet need reinforcing bar split heads, comprises split head support and liftable couple, and wherein the split head support comprises two "U" type landing legs and a horizontal pole of falling, and the peak of two landing legs is connected to the horizontal pole, is equipped with the scale mark of vertical direction on one of them landing leg, and horizontal pole side is equipped with the screw thread sleeve, the liftable couple comprises twist grip, threaded montant and couple, threaded montant and threaded bush connection take, twist grip sets up in threaded montant top, takes threaded montant below to set up the couple.
Preferably, the U-shaped support leg is formed by bending a steel bar with the diameter of 16-20mm, the height of the support leg is 250-350mm, and a scale mark in the vertical direction is arranged on one support leg and can be used for the elevation of a cast-in-place member during pouring. The horizontal cross bar is formed by welding a reinforcing steel bar with the diameter of 18-20mm and the length of 80-120mm with a sleeve with threads.
Preferably, the diameter of the threaded vertical rod is equal to the inner diameter of the threaded sleeve, the length of the threaded vertical rod is 180 mm and 240mm, and the hook and the threaded vertical rod can rotate relatively.
Due to the adoption of the form of the lifting hook, the split heads can be suitable for cast-in-place plane structures with different thicknesses.
The utility model provides an upper floating type steel bar split heads capable of being circulated. The using steps are as follows:
step one, determining the distance between an upper layer reinforcing mesh of a cast-in-place planar structure to be fixed and the bottom surface of the structure according to design requirements. The distance is less than or equal to 250mm, namely the fixed upper layer of reinforcing mesh is ensured to be positioned below the horizontal plane where the horizontal cross bar of the split heads bracket is positioned;
rotating a rotating handle to adjust the relative height of the liftable hook, and rotating the rotating handle to enable the distance between the hook and the bottom of the U-shaped supporting leg to be equal to the distance between an upper-layer steel bar of a cast-in-situ sheet surface structure to be fixed and the bottom surface of the structure;
thirdly, after the steel mesh sheets are bound, arranging the split heads at certain intervals;
fourthly, pouring, tamping and leveling concrete, rotating the liftable hook immediately before initial setting of the concrete to enable the hook to slightly move downwards, then slightly moving the split heads integrally in the direction far away from the fixed steel bars, and removing and lifting the split heads integrally;
and fifthly, filling and trowelling the hole formed after the split heads are removed by concrete.
The utility model has the advantages that:
a reinforcing bar split heads can have enough to meet need to come up formula, overcome the tradition split heads that is using at present and can only disposable, the shortcoming of extravagant material. The effects of turnover, repeated use, material waste avoidance, green energy conservation and engineering cost reduction are realized; the structure form of adopting the liftable can be applicable to the structure of different sizes.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention.
As shown in the figure, the floating type turnover reinforcing steel bar split heads of the utility model consists of a split head support 1 and a lifting hook 2; the steel bar split heads support 1 is composed of two U-shaped supporting legs 11 and a horizontal cross rod 12, wherein one of the supporting legs is provided with a scale mark 13 which can be used for the elevation of a cast-in-place member during pouring (the thickness of a floor slab is controlled). The U-shaped supporting leg 11 is formed by bending a steel bar with the diameter of 18mm, the height of the supporting leg is about 300mm, and the height of the supporting leg is larger than that of a cast-in-situ plane to be constructed. The horizontal cross bar 12 is formed by welding two reinforcing bars with a diameter of 18mm and a length of about 100mm with a sleeve 13 with threads. The horizontal cross bar 12 is provided with a threaded sleeve 14 along the length thereof towards the middle for connecting the liftable hook 2. Liftable couple 2 comprises twist grip 21, threaded montant 22 and couple 23, and wherein couple 23 is used for hooking column floor upper reinforcing bar net piece 3, and it can rotate relatively with threaded montant 23 to realize rotating twist grip 21, when liftable couple descends, the couple can follow the effect that the unhook was gone out of reinforcing bar net piece 3. The threaded vertical rod 22 has a diameter equal to the inner diameter of the threaded sleeve 13 and a length of about 200mm, and the hook and the threaded vertical rod 22 can rotate relatively. Due to the adoption of the form of the lifting hook 2, the split heads can be suitable for cast-in-place plane structures with different thicknesses.
The utility model has the advantages of convenient use, firmness, reliability, repeated use, material saving and engineering cost reduction.
