Abstract
The utility model provides a floor elevation and roughness controlling means, pour the upper and lower atress reinforcing bar in the template including locating the concrete floor, the interval is equipped with a plurality of concrete split headss in its characterized in that template, and each concrete split heads top surface is equipped with and supports the ascending upper groove of notch of going up the atress reinforcing bar, and the bottom surface is equipped with the decurrent low groove of the notch that blocks down on the atress reinforcing bar, still is equipped with vertical sighting rod on the concrete split heads. Vertical sighting rod through on the concrete split heads carries out the height index, makes level, has solved the complex operation that welding reinforcing bar sighting rod brought, has influenced reinforcing bar quality scheduling problem, gives the operational environment of a no light pollution of constructor. With the traditional reinforcing bar split heads of concrete split heads replacement, both saved steel, can pass through its rigid support, the concrete cover thickness of atress reinforcing bar on the effective control again.
Description
Technical field
The utility model relates to a kind of control device, particularly a kind of floor absolute altitude and planeness control device, belongs to building surveying apparatus design and manufacturing technology field.
Background technology
In building engineering construction, control cast-in-situ steel reinforced concrete flooring absolute altitude is an important construction technology, and it will directly affect the qualitative problems of construction caused because slab thickness is not up to standard.Traditional construction welds vertical reinforcing rod on floor steel bar stress, then measure flooring absolute altitude with level gauge, and then on reinforcing rod, levelling draws elevation line.This practice construction is loaded down with trivial details, needs the artificial electric welding machine that uses to carry out Site Welding.And easily making floor steel bar stress occur stinging meat phenomenon during welding, the light pollution simultaneously produced during welding, also easily stimulates the eyes of constructor around.In addition; traditional steel bar horse-shaped bench is converted into " several " font with reinforcing bar; steel bar stress in floor inner support; but because " several " font steel bar horse-shaped bench rigidity is poor; easily be out of shape by External Force Acting and form surface of subsidence in concrete casting, being finally difficult to the thickness of concrete cover controlling steel bar stress.Therefore be necessary to be improved prior art.
Summary of the invention
For solve existing concrete flooring build time, use traditional Site Welding spacer bars, and bring complex operation step, and cause the problems such as harmful effect to surrounding people and reinforcing bar, the utility model provides a kind of floor absolute altitude and planeness control device.
The utility model is completed by following technical proposal: a kind of floor absolute altitude and planeness control device, comprise that to be located on concrete floor formwork for placing upper, lower stress reinforcing bar, it is characterized in that template being interval with multiple concrete split heads, each concrete split heads end face is provided with the notch upper groove upwards supporting upper steel bar stress, bottom surface is provided with the downward low groove of the notch blocked on lower stress reinforcing bar, concrete split heads is also provided with vertical marker post, to carry out concrete floor absolute altitude by the vertical marker post on concrete split heads to determine and levelling, without the need to carrying out Site Welding, simply, convenient, safety, simultaneously by the rigid support of concrete split heads, effectively can control the thickness of concrete cover of steel bar stress.
Described concrete split heads side arranges bar shaped keyway, to increase the adhesion with concrete floor, ensures concrete floor quality, prevents flooring from producing crack.
Described concrete split heads is set to the prismatoid that top is little, bottom is large, to increase stability.
Described vertical marker post is threaded rod, and the lower end of this threaded rod is placed in concrete split heads top, and upper end upwards extends, and on threaded rod, be provided with floor absolute altitude control mark, and marks with this and determine concrete building plate height.
The utility model has following advantages and effect: adopt such scheme, template easily before floor is built can place concrete split heads in interval, and support upper steel bar stress with the upper groove of concrete split heads end face, the low groove of bottom surface is stuck on lower stress reinforcing bar, and the vertical marker post upper end on concrete split heads upwards extends, to carry out the number of altitude, levelling when watering floor concrete by vertical marker post.Fundamentally solve traditional Site Welding reinforcing bar mark post to bring complex operation step, affect steel bar quality, cause reinforcing bar to sting the problems such as meat, create the working environment that does not have light pollution to constructor.Replace traditional steel bar horse-shaped bench with this concrete split heads, can not only save steel, what is more important to the rigid support of upper steel bar stress, effectively can control the thickness of concrete cover of steel bar stress by concrete split heads.The utility model is simple, convenient, safe, reliable, and saves steel, decreasing pollution, and construction civilization is a desirable mark for building in fact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A figure of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further, and the accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The floor absolute altitude that the utility model provides and planeness control device, comprise and be located at upper steel bar stress 4 on concrete floor formwork for placing 1 and lower stress reinforcing bar 3, concrete floor formwork for placing 1 is interval with multiple concrete split heads 2, the thickness of the height=slab thickness-upper steel bar stress concrete cover of each concrete split heads 2, bar shaped keyway 21 is provided with in each concrete split heads 2 two sides, to increase the adhesion with concrete floor 5, ensure concrete floor quality, prevent flooring from producing crack, each concrete split heads 2 end face is provided with the notch upper groove 23 upwards supporting upper steel bar stress 4, be used for controlling the thickness of concrete cover of steel bar stress 4, bottom surface is provided with the downward low groove 24 of the notch be stuck on lower stress reinforcing bar 3, each concrete split heads 2 is also provided with vertical marker post 22.Described concrete split heads 2 is set to the prismatoid that top is little, bottom is large, to increase stability; Described vertical marker post 22 is threaded rod, and the lower end of this threaded rod is placed in concrete split heads 2 top, and upper end upwards extends, and on threaded rod, be provided with floor absolute altitude control mark, and the height of the upper surface 6 determining concrete floor 5 is marked with this, facilitate levelling simultaneously, control flooring planeness.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all in spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
