Because the construction of concrete cover belongs to concealed work, generally the off normal of reinforcing bar or the deviation of protective layer thickness are difficult to be found after concreting, also cannot remedy afterwards.In fact; the control of thickness of concrete cover is the weak link in Construction Quality management always; cause the main cause of this present situation to have the quality of construction team lower, the level of execution control is not high, the lacking a sense of responsibility of supervisor, cloth muscle is unreasonable etc., takes in addition scientific and reasonable technical measures also very important.
In the current construction work of China, the method for conventional control topping is before construction, to make concrete pad, when construction by cushion block colligation in negative reinforcement bottom, guarantee its protective layer thickness, this method shortcoming is more, and the one, will be through the curing time of 28 days in manufacturing process; The 2nd, the intensity of cushion block is low, and trampling when each professional operating personnel constructs after installing easily causes cushion block cracked; The 3rd, because cushion block and negative reinforcement net can not form entirety, the position of a large amount of negative reinforcements can produce skew in the time building, and causes rebar spacing to differ, and causes the unbalance stress of plate.
Summary of the invention
The utility model provides a kind of negative reinforcement to hang the device of construction control topping; simple in structure light and handy; easy to use, input cost is low, the position that can effectively guarantee steel bar stress in concrete structure accurately and negative reinforcement protective layer thickness meet the requirements.
In order to achieve the above object, the utility model is realized by the following technical solutions:
A kind of negative reinforcement hangs the device of construction control topping; comprise tripod supporting seat, horizontal fixed cross beam, fixing wiring; described tripod supporting seat bottom stable support triangular in shape; one section of brace summer of welding on it; described horizontal fixed cross beam is erected on the brace summer of tripod supporting seat; on horizontal fixed cross beam, hang several fixing wirings, be used for the fixing negative reinforcement of colligation.
Described tripod supporting seat is formed by reinforcement fabrication, and its triangular support upper end is concentrated and is welded on brace summer, and three of bottoms fulcrum is along the circumferential direction uniformly distributed in same level.
Described horizontal fixed cross beam adopts steel pipe or the lumps of wood to make.
Described fixing wiring adopts iron wire to make.
The height of described tripod supporting seat is determined according to structure thickness of slab in design drawing, higher than structural slab upper surface 5mm.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model is simple in structure light and handy, utilizes General building construction material to make, and favourable reducing costs reduced auxiliary material and dropped into.
2. the utility model is easy to use, can significantly improve construction speed, guarantees workmanship.
3. the utility model has overcome the low shortcoming of conventional cushion bulk strength, makes to form an integral network structure between negative reinforcement, has greatly strengthened the resistance to overturning of bar construction.
4. the position that the utility model can effectively guarantee steel bar stress in concrete structure accurately and negative reinforcement protective layer thickness meet the requirements.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
Seeing Fig. 1, is the structural representation of device described in the utility model, comprises tripod supporting seat 1, horizontal fixed cross beam 2, fixing wiring 3.
Seeing Fig. 2, is device tripod clamping support schematic diagram described in the utility model, and described tripod supporting seat 1 is formed by reinforcement fabrication, preferably
above reinforcing bar, its triangular support upper end is concentrated and is welded on brace summer, and bottom fulcrum is along the circumferential direction uniformly distributed in same level, bottom stable support triangular in shape;
Seeing Fig. 3-Fig. 4, is device scheme of installation described in the utility model, and described horizontal fixed cross beam 2 adopts steel pipe or the lumps of wood to make, preferably
steel pipe, is erected on the brace summer of tripod supporting seat 1, hangs several fixing wirings 3 on horizontal fixed cross beam 2, is used for the fixing negative reinforcement 4 of colligation, and fixing wiring 3 adopts iron wire to make, preferably 22# line.Tripod supporting seat 1 and horizontal fixed cross beam 2 are installed respectively after negative reinforcement 4 colligations of cast in place concrete plate complete, and tripod supporting seat 1 is fixed on the soffit formwork upper surface having propped up, and horizontal fixed cross beam 2 is fixed on tripod supporting seat 1.Tripod supporting seat 1 is placed into the centre position of adjacent negative reinforcement 4 according to the spacing of 1.5-2m, adjust spacing, and should arrange continuously according to site specific.
