Abstract
The utility model relates to a floor hogging moment protective layer thickness control device. The floor hogging moment protective layer thickness control device comprises a reinforcement handle, a steel pipe lantern ring, a reinforcement shaft and a reinforcement bracket, wherein the reinforcement handle is fixedly connected with the steel pipe lantern ring; the steel pipe lantern ring is movably connected with the reinforcement shaft; and the reinforcement shaft is fixedly connected with the reinforcement bracket. The device has the advantages that the control effect on the thickness of the protective layer is good, the device is simple in production, convenient in construction and low in construction cost, and can be reused.
Description
Technical field
The utility model relates to the reinforced concrete construction field, relates in particular to a kind of floor negative bending moment rib protective layer thickness control device.
Background technology
Cast in place concrete plate class A of geometric unitA negative reinforcement for general industry and civilian construction, especially the plate face negative reinforcement of overhanging component, owing to mostly being the I grade reinforcing steel, general diameter is less, add that the rigidity of material own is low, in the work progress owing to being subjected to the impact force of fluid concrete and trampling of constructor, floor negative bending moment rib that distortion is arranged more or sinking, have in addition drop to below the natural axis.And the thickness of concrete cover belongs to concealed work; unless the serious quality accidents such as reinforcing steel bars exposed, concrete hole occur; the deviation of the off normal of reinforcing bar or protective layer thickness is difficult to be found after concreting generally speaking; also can't remedy, so the control of floor negative bending moment rib protective layer thickness is in weak link always afterwards.
At present, floor negative bending moment rib protective layer thickness control way commonly used is the cushion block that adopts the vinyl polymer material to make in the construction work, or steel bar horse-shaped bench.The cushion block that the vinyl polymer material is made is because rigidity is inadequate, and trampling during workman's concreting easily makes cushion block damage or displacement.And steel bar horse-shaped bench rigidity meets the demands, but construction cost is high.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of floor negative bending moment rib protective layer thickness control device, and the control of unit protection layer thickness is effective, makes simple, easy to operate, reusable.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of floor negative bending moment rib protective layer thickness control device comprises reinforcing bar handle, the steel pipe collar, reinforcing bar axle, Steel bar rack, and the reinforcing bar handle is fixedly connected with the steel pipe collar, and the steel pipe collar and reinforcing bar axle are flexibly connected, and the reinforcing bar axle is fixedly connected with Steel bar rack.
Compared with prior art, the beneficial effects of the utility model are:
The control of unit protection layer thickness is effective, makes simply, and easy construction, reusable, construction cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-reinforcing bar handle 2-steel pipe collar 3-reinforcing bar axle 4-Steel bar rack 5-floor negative bending moment rib
The specific embodiment
Below in conjunction with Figure of description the utility model is described in detail:
A kind of floor negative bending moment rib protective layer thickness control device; see Fig. 1, comprise reinforcing bar handle 1, the steel pipe collar 2, reinforcing bar axle 3, Steel bar rack 4, reinforcing bar handle 1 is fixedly connected with the steel pipe collar 2; the steel pipe collar 2 is flexibly connected with reinforcing bar axle 3, and reinforcing bar axle 3 is fixedly connected with Steel bar rack 4.
During making, reinforcing bar handle 1 and the steel pipe collar 2 are welded together, the steel pipe collar 2 covers are through on the reinforcing bar axle 3 of Steel bar rack 4, rotate reinforcing bar handle 1 the reinforcing bar collar 2 is rotated around reinforcing bar axle 3.
When the floor bar concrete construction, this device is placed on the slab form that has installed, be used for supporting floor negative reinforcement 5, and adjust in advance height by slab thickness and thickness of protection tier, treat that floorslab concrete pouring is complete this device is extracted.
The utility model can make protective layer thickness control effective, makes simply, and easy construction, reusable, construction cost is low.
Above described only be basic principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
