Abstract
The utility model discloses a simple steel bar bracket controlling the height of a net section of a negative bar, which comprises a cross rod and vertical rods, wherein the cross rod is a long steel bar, the vertical rod comprises a steel rod, a sleeve, a hanging hook, a positioning pin and a positioning bolt, the hanging hook is a short cross rod, the short cross rod is welded on the surface of the sleeve and is perpendicular to the sleeve, the positioning pin is positioned above the hanging hook and is connected with the sleeve, the sleeve is sleeved on the steel rod in a sliding mode, the sleeve is provided with a screw hole, and the sleeve is fixed on the steel rod through the positioning bolt and the screw hole; both ends of the cross rod are respectively connected with upper ends of the two vertical rods, and the cross rod and the two vertical rods form an n-shaped structure. The distance from the hanging hook to a supporting foot is controlled through the ascending and descending of the sleeve, so the height of the net section of the negative bar is controlled, and simultaneously the thickness of a concrete protective layer is controlled through the positioning pin. The steel bar bracket has a simple structure and a low cost, is durable, can be reused, and saves materials.
Description
[technical field]
The utility model relates to the building operations apparatus, relates in particular to a kind ofly to be used to control negative muscle net section height, to control the simple and easy Steel bar rack of thickness of concrete cover simultaneously.
[background technology]
The negative muscle net section height (negative tendon protective layer) of traditional cast in place concrete plate is realized below reinforcing bar with reinforced rail foot pad or concrete pad; be easy to be trampled distortion or displacement at work progress; so that can't guarantee the thickness of plate negative tendon protective layer; it is too high that the reinforced rail foot pad is that steel product cost is also wasted in disposable use, and concrete pad is difficult to guarantee structural integrity and and strength matching etc.
[summary of the invention]
The technical problems to be solved in the utility model provides a kind of simple and easy Steel bar rack muscle that is used for the negative muscle net section of control panel height, controls thickness of concrete cover simultaneously.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is that a kind of simple and easy Steel bar rack of controlling negative muscle net section height comprises cross bar and vertical rod; Cross bar is long reinforcing bar, vertical rod comprises round steel, sleeve, hook, alignment pin and positioning bolt, hook is the hyphen bar, the hyphen bar is welded on sleeve surface and vertical with sleeve pipe, alignment pin is positioned at the top of hook and is connected with sleeve, sleeve slides on the round steel, and sleeve is provided with screw, positioning bolt with by screw sleeve is fixed on the round steel; The two ends of cross bar are connected with the upper end of 2 vertical rods respectively, and cross bar and 2 vertical rods constitute " ㄇ " shape structure.
As preferably, described vertical rod also comprises angle steel, and described angle steel is welded on the lower end of round steel, and the angle steel opening down.
As preferably, the two ends of described cross bar are welded on the upper end of 2 vertical rods respectively.
The beneficial effects of the utility model are:
The distance that hooks into leg is controlled by the sleeve lifting, and the negative muscle net section of control height is controlled thickness of concrete cover by alignment pin simultaneously thus.It is simple in structure durable, can reuse, and economical with materials, with low cost.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of simple and easy Steel bar rack embodiment front view of controlling negative muscle net section height of the utility model.
Fig. 2 is a kind of simple and easy Steel bar rack embodiment right view of controlling negative muscle net section height of the utility model.
Among the figure, 1-hook, 2-round steel, the long reinforcing bar of 3-, 4-angle steel, 5-sleeve, 6-positioning bolt, 7-pin.
[specific embodiment]
In Fig. 1 and Fig. 2, be a kind of easy Steel bar rack, form by cross bar, vertical rod.Cross bar is long reinforcing bar 3, vertical rod is made up of with hook round steel 2, sleeve 5, sleeve 5 slides on the round steel 2, hook 1 is a hyphen bar, one end of hyphen bar is welded on sleeve 5 surfaces and vertical with sleeve surface, the other end is outwards flat to be stretched, and sleeve is provided with screw, sleeve 5 is fixed on the round steel 2 by screw with positioning bolt 6.Weld with the upper end of 2 vertical rods respectively at the two ends of cross bar, and cross bar and 2 vertical rods constitute " ㄇ " shape structures.
Be to guarantee the distance (protective layer thickness) of cast back concrete upper surface, be 27 millimeters apart at the top and the hook 1 of sleeve and locate boring, insert the witness markers of pin 7 as the concrete upper surface after pouring into a mould to upper reinforcement.Concreting to the concordant thickness that can guarantee concrete cover of pin 7 soffits.
For preventing that support from laying the back and sliding, a bit of angle steel 4 is welded on the lower end of round steel, the angle steel opening forms anti-skidding spike down.
For adapting to the floor requirement of different-thickness, can slide up and down along round steel 2 by sleeve 5, and then the screwed in place bolt is fixed on sleeve on the height that needs.
When installing and using, the angle steel spike of vertical rod is placed on the plane, regulates the height of the flat hook of stretching 1 in advance,, like this plate is born the muscle edge and hang on the hook with hooking the floor upper reinforcement.After the concreting,, just can withdraw from hook, take out support then and dismounting is removed from reinforcing bar as long as vertical rod is tilted backward slightly.
