Abstract
The utility model discloses a kind of arc iron, comprise the arc iron body of annular, the center of described arc iron body is in frustum or columned raised support portion, the large end bending in raised support portion also stretches out, form bottom erection loop, shape a in an angle between the one side that raised support portion contacts with bottom erection loop and bottom erection loop.The invention also discloses a kind of stake reinforcement installation structure, comprise the reinforcing cage be vertically arranged in stake holes, along short transverse on reinforcing cage, be provided with some groups of arc iron bodies, often organize arc iron body circumferentially to arrange on reinforcing cage, and being at least provided with three, described arc iron body protrusions support portion is equal with the distance between reinforcing cage and stake holes hole wall with the vertical distance between erection loop upper surface, bottom.The arc iron construction that the utility model obtains is simple, and arc iron is arranged on the mounting structure in reinforcing cage circumference, can the installation thickness of effective Control protection layer, can effectively prevent again reinforcing cage from occurring offseting.
Description
Technical field
The utility model relates to a kind of construction work foundation construction technical field, and particularly a kind of reinforcing cage that can effectively prevent is in the arc iron of stake holes bias internal and the stake reinforcement installation structure adopting this arc iron.
Background technology
During the employing engineering castinplace pile of building foundation, first machine drilling or the operation of manually digging hole pore-forming is carried out according to scheme in construction, when sediment thickness at the bottom of bearing stratum, hole at the bottom of hole and the project acceptance inspection such as aperture, verticality qualified after, pile cages shaping for colligation is hung in stake holes in place.Topping scope between hole wall and stake reinforcing bar ties cushion block and after fixing sound detecting pipe, then starts continuous placing pile body concrete.
In practical operation, the topping of stake reinforcing bar in stake holes ties the safeguard measure of cushion block by various factors.1, rarefaction of air and may poisonous gas be had in part stake holes in deep hole stake, operating personnel cannot tie topping cushion block down to stake bottom; 2, underwater casting stake concrete technology operating personnel cannot operate in stake holes; 3, by the sense of responsibility of operating personnel and the impact of operating technology, tie cushion block not in place in stake holes, cause pile cages to be still partial to side in hole, topping is comparatively large, and another side is less, and even hole wall is close to by stake reinforcing bar in local.
Summary of the invention
The purpose of this utility model is to provide a kind of structure arc iron simple, easy for installation and adopts the stake reinforcement installation structure of this arc iron, solves in foundation construction, and when reinforcing cage is in stake holes, topping is installed not in place, easily causes reinforcing cage to occur skew.
To achieve these goals, the arc iron of one designed by the utility model, comprise the arc iron body of annular, the center of described arc iron body is in frustum or columned raised support portion, the large end bending in raised support portion also stretches out, form bottom erection loop, shape a in an angle between the one side that raised support portion contacts with bottom erection loop and bottom erection loop.
Further, described bottom erection loop is tabular, and described angle a, between 30 ° ~ 90 °, ensure that the installation strength of arc iron body.
A kind of stake reinforcement installation structure, it comprises the reinforcing cage be vertically arranged in stake holes, along short transverse on reinforcing cage, be provided with some groups of arc iron bodies, often organize arc iron body circumferentially to arrange on reinforcing cage, and being at least provided with three, the vertical distance between described arc iron body protrusions support portion and erection loop upper surface, bottom is not more than the distance between reinforcing cage and stake holes hole wall.
Compared with prior art, the arc iron that obtains of the utility model and the stake reinforcement installation structure tool that adopts this arc iron have the following advantages:
1, arc iron construction is simple, and cost is low.
2, arc iron is arranged on reinforcing cage, can the installation thickness of effective Control protection layer, thus overcome operation in deep hole stake and underwater casting concrete technology and artificial lower opening.
3, arc iron and stake holes are close to, and can effectively prevent reinforcing cage from occurring skew.

Fig. 2 is the schematic cross-section of arc iron in embodiment;
Fig. 3 is the installment state schematic diagram of arc iron and reinforcing cage in embodiment.
In figure: arc iron body 1, bottom erection loop 11, raised support portion 12, reinforcing cage 2, stake holes 3.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
The arc iron (as shown in Figure 1 and Figure 2) that the present embodiment provides, comprise the arc iron body 1 of annular, the center of described arc iron body 1 is in frustum or columned raised support portion 12, the large end bending in raised support portion 12 also stretches out, form bottom erection loop 11, described bottom erection loop 11 is in tabular; Between the one side that raised support portion 12 contacts with bottom erection loop 11 and bottom erection loop 11, shape a in an angle, angle a are 45 °.
As shown in Figure 3, a kind of stake reinforcement installation structure, it comprises the reinforcing cage 2 be vertically arranged in stake holes 3, along short transverse on reinforcing cage 2, is provided with some groups of arc iron bodies 1, often organizes arc iron body 1 and circumferentially arrange on reinforcing cage 2, and be at least provided with three; Described arc iron body 1 protrusions support portion 12 is (h) equal with the distance between reinforcing cage 2 and stake holes hole wall shown in figure with the vertical distance between bottom erection loop 11 upper surface.
When specifically installing, longitudinally height and diameter according to reinforcing cage 2 determine row and the number of the arc iron body 1 that will install.In the present embodiment, the vertical spacing between the arc iron body 1 of adjacent two row is 2 meters, and each row is provided with 4 arc iron bodies 1.
In order to ensure the steadiness of arc iron body 1, in the present embodiment, all arc iron bodies 1 are all welded on reinforcing cage.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, although applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
