Abstract
The utility model discloses a positioning device of an upper reinforcement protective cover of a cast-in-place slab. The positioning device comprises a bracket, a pressing rod and a position adjusting nut, wherein the bracket is of a retractable structure; the position adjusting nut is welded on the bracket; and the pressing rod is movably connected with the position adjusting nut. According to the positioning device disclosed by the utility model, not only can the thickness of the upper reinforcement protective cover of the cast-in-place slab be guaranteed, but also reinforcement saddle iron is saved and resources are not wasted; and the positioning device of the upper reinforcement protective cover of the cast-in-place slab can be used for a plurality of times. The common fault of quality is controlled and the quality of engineering is further guaranteed. Furthermore, the bracket is of the retractable structure so that people can conveniently adjust the height in a construction process and the positioning device is convenient to store and carry.
Description
Technical field
The utility model relates to a kind of apparatus for positioning cast-in-place board upper reinforcement protective layer, belongs to technical field of building construction.
Background technology
Adopt at present common reinforcing bar horse sledge and elongated reinforcing bar horse sledge to control the upper reinforcement protective layer thickness in engineering, obtained certain safeguard measure, weak point at the construction Bars In Poured Concrete Slab: 1, the consumption of split heads is large, has wasted great deal of steel.2, in constructing operation, trampling of personnel caused the part reinforcing bar to move down and horizontal movement, destroyed the globality of reinforcing bar.3, concrete free-falling when being transported to operation layer causes top negative bending moment bar bending, greatly reduces the stress performance of reinforcing bar.Can not adjust again after fluid concrete, affect the quality of construction.
The utility model content
In order to address the above problem, the utility model provides a kind of apparatus for positioning cast-in-place board upper reinforcement protective layer, can effectively solve the problem of above-mentioned prior art deficiency.
To achieve these goals; the technical solution adopted in the utility model is: a kind of apparatus for positioning cast-in-place board upper reinforcement protective layer, comprise support, depression bar, positioning nut, and support is the extension type structure; the positioning nut-welding is on support, and depression bar is flexibly connected with the positioning nut.
As preferably, the depression bar front end is hook solid.
As preferably, the positioning nut adopts common hex nut.
The utility model has the advantage of: not only guaranteed the thickness of cast-in-place board upper reinforcement protective layer, can save the reinforcing bar stirrup again, do not wasted resource, and apparatus for positioning cast-in-place board upper reinforcement protective layer also can repeatedly use.Both control the common fault of quality, guaranteed again the quality of engineering.In addition, support is made as the extension type structure, both has been convenient to people and regulates height in the process of construction, be convenient to again take in, carry.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, support; 2, depression bar; 3, nut.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Referring to Fig. 1, a kind of apparatus for positioning cast-in-place board upper reinforcement protective layer comprises support 1, depression bar 2, positioning nut 3, and support 1 is the extension type structure, and positioning nut 3 is welded on support 1, and depression bar 2 is flexibly connected with positioning nut 3.Depression bar 2 front ends are hook solid, and positioning nut 3 adopts common hex nut 3.
After the complete cast-in-place board upper reinforcement of colligation, with being placed on template after the support 1 of apparatus for positioning cast-in-place board upper reinforcement protective layer and nut 3 welding of transposing, regulate cast-in-place board upper reinforcement identical with the reinforcing bar height of support 1 leg.Can place 2-3 support 1 for every square metre, penetrate depression bar 2 in the positioning nut 3 on support 1 top, make the leading hook of depression bar 2 hook the upper reinforcement of Bars In Poured Concrete Slab, depression bar 2 rear ends be flattened tie up on the reinforcing bar of the plane of support 1 with iron wire.Thereby be controlled at when annotating concrete, reinforcing bar does not move down.After pouring concrete, in the concrete leveling process, apparatus for positioning cast-in-place board upper reinforcement protective layer is proposed at any time in front, then be arranged on other Bars In Poured Concrete Slab reinforcing bars of not pouring into a mould.Not only guaranteed the thickness of cast-in-place board upper reinforcement protective layer, can save the reinforcing bar stirrup again, do not wasted resource, and apparatus for positioning cast-in-place board upper reinforcement protective layer also can repeatedly use.Both control the common fault of quality, guaranteed again the quality of engineering.In addition, support 1 is made as the extension type structure, both has been convenient to people and regulates height in the process of construction, be convenient to again take in, carry.
Claims (3)
1. apparatus for positioning cast-in-place board upper reinforcement protective layer, it is characterized in that: comprise support, depression bar, positioning nut, support is the extension type structure, and the positioning nut-welding is on support, and depression bar is flexibly connected with the positioning nut.
2. apparatus for positioning cast-in-place board upper reinforcement protective layer according to claim 1, it is characterized in that: the depression bar front end is hook solid.
